Description
Technical Field
The present invention relates generally to compact disc players and radio receivers and, more particularly, to a combined multiple compact disc player and radio receiver for an automobile.
Background Art
Generally, a radio receiver for an automobile has electronic tuning preset station memory switches. A user presets the memory switches to correspond to the favorite radio stations. Accordingly, by pressing a memory switch the radio receiver automatically tunes to the radio station corresponding to the selected switch.
Automobile radio receivers are now being combined with single compact disc (CD) players. Single CD players are able to store and play one CD at a time.
In-dash multiple CD players for automobiles such as the Fujitsu Ten six disc CD player are also available. A disadvantage associated with typical multiple CD players for automobiles is that they have a confusing method of operation and are separate units from the radio receiver.
Disclosure of the Invention
A general object of the present invention is to provide a combined multiple CD player and radio receiver for an automobile.
In carrying out the above object and other objects, features, and advantages, the present invention provides a combined compact disc/radio system for an automobile. The system includes a multiple compact disc player, a radio receiver, and a controller. The multiple compact disc player is provided with a magazine having n individual slots for storing n compact discs. The controller has a bezel provided with an eject button, a load button, n memory buttons each corresponding to a respective one of the slots, an information display area, and a single compact disc slot for inserting and removing compact discs from the multiple compact disc player.
The memory buttons function as radio tuning preset station memory switches when the radio receiver is operating and function to identify slots to be loaded and unloaded when the multiple compact disc player is operating.
In accordance with the system of the present invention, methods of operating the system are also provided.
The advantages to the present invention are numerous. The present invention provides for compact disc insert, eject, auto insert, and auto eject using several different methods with only one additional button (the load button) than a standard one compact disc player and radio receiver combined system. This allows for user flexibility and an ergonomic bezel design. The present invention also provides display information to improve feedback for ease of use.
These and other features, aspects, and embodiments of the present invention will become better understood with regard to the following description, appended claims, and accompanying drawings.

Best Modes for Carrying Out the Invention
Referring now to FIG. 1, a combined multiple CD player and radio receiver system 10 for carrying out the method of the present invention is shown. System 10 is preferably an in-dash unit for an automobile. System 10 includes a multiple CD player 12, a radio receiver 14, and a controller 16.
Controller 16 includes an eject button 18, a load button 20, preferably six memory buttons 22(a-f), and a changeover button 24. Controller 16 controls system 10 via changeover button 24 to operate in either a CD or radio mode. In the CD mode, multiple CD player 12 plays a CD. In the radio mode, radio receiver 14 plays a selected radio station.
Multiple CD player 12 includes a magazine having n individual slots (not specifically shown) for storing n CDs where n is equal to the number of memory buttons. Each of memory buttons 22(a-f) correspond to a respective one of the slots. Thus, multiple CD player 12 is preferably a six disc CD player. Multiple CD player 12 is operable to play one CD on a slot at a time and to load and eject CDs from the other slots while the one CD is playing.
Referring now to FIGS. 2 and 3, with reference to FIG. 1, a bezel 30 for the combined multiple CD player and radio receiver system 10 is shown. Bezel 30 preferably sticks out of a dashboard of an automobile and provides a user with accessibility to eject button 18, load button 20, memory buttons 22(a-f), and changeover button 24. Bezel 30 also includes a single CD opening 34 for receiving and ejecting one CD at a time from multiple CD player 12. A door 35 is operable with CD opening 34 to provide and restrict access to CD opening 34.
To load a CD onto an empty slot of the magazine of multiple CD player 12, the user inserts a CD into CD opening 34. The magazine vertically moves within multiple CD player 12 to align the empty slot to be loaded with CD opening 34. The CD inserted into CD opening 34 is then pulled through the CD opening and pushed onto the empty slot to load the slot.
To eject a CD from a loaded slot, the magazine vertically moves to align the loaded slot to be emptied with CD opening 34. The CD on the loaded slot is then pulled off of the slot and pushed through CD opening 34 to empty the slot.
Bezel 30 further provides a display area 32 for the user. Display area 32 indicates to the user operating information of system 10. Display area 32 includes CD display circles 36(a-f). Inside CD display circles 36(a-f) are CD display numbers 37(a-f).
CD display circles 36(a-f) are continuously lighted except when the magazine is moving or when a CD is being loaded or unloaded from a slot. When the magazine is moving or when a CD is being loaded or unloaded, CD display circles 36(a-f) flash on and off in sequential order.
CD display numbers 37(a-f) correspond to respective slots of the magazine of multiple CD player 12. CD display numbers 37 corresponding to slots loaded with CDs are lighted to indicate to the user which slots of multiple CD player 12 are loaded. Correspondingly, CD display numbers 37 corresponding to empty slots are not lighted thereby indicating to the user which slots of multiple CD player 12 are empty.
Display area 32 further includes an information display area 38 for displaying to the user alphanumeric information regarding operation information of system 10. An FM display 40 on display area 32 lights up when system 10 is operating in the radio mode with FM reception. Similarly, an AM display 42 lights up when system 10 is operating in the radio mode with AM reception.
Controller 16 controls multiple CD player 12 and radio receiver 14 in accordance with selections made by a user by pressing the aforementioned buttons. Controller 16 allows the user to insert CDs into selected empty slots, eject CDs from selected loaded slots, automatically insert CDs into all of the empty slots, and automatically eject CDs from all of the loaded slots. The user can perform all of these functions by pressing eject button 18, load button 20, and memory buttons 22(a-e) in accordance with methods illustrated in FIGS. 4-8.
Referring now to FIG. 4, with continual reference to FIGS. 1-3, a flow diagram 50 illustrating operation for ejecting a single CD from multiple CD player 12 when system 10 is operating in either of the CD or radio modes is shown. Flow diagram 50 begins with the user pressing eject button 18 as shown by block 52. Decision block 54 then determines if all of the slots of the magazine of multiple CD player 12 are empty. If all of the slots are empty, then information display area 38 displays information such as "NO CD" as shown by block 56 to indicate to the user that all of the slots are empty. CD display circles 36(a-f) then continuously light as shown by block 58 to notify the user that the magazine is not moving and that multiple CD player 12 is not loading or unloading a CD from a slot.
If decision block 54 determines that at least one of the slots is loaded with a CD, then information display area 38 displays information such as "SELECT CD" as shown by block 60 to indicate to the user to select a slot in which the user wishes to eject a CD from. CD display numbers 37(a-f) corresponding to the loaded slots then flash as shown by block 62 to indicate to the user which slots are loaded. CD display circles 36(a-f) then continuously light as shown by block 64.
Decision block 66 then determines if a first time period has expired before the user has pushed a memory button 22(a-f). If the user pushes a memory button 22(a-f) before the first time period has expired, then decision block 68 determines if the slot corresponding to the pushed memory button is loaded with a CD. If the slot corresponding to the pushed memory button is empty, then information display area 38 displays information such as "NO CD" as shown by block 70 to indicate to the user that the selected slot is empty.
If decision block 68 determines that the selected slot is loaded with a CD, or if decision block 66 determines that the first time period has expired before the user has pushed a memory button 22(a-f), then the magazine moves to align the selected slot with CD opening 34. If a slot has not been selected by the user by pushing a memory button 22(a-f), then the selected slot is automatically the loaded slot corresponding to the last CD played by multiple CD player 12. The CD on the selected slot is then pulled off of the slot and pushed through CD opening 34. Information display area 38 then displays information such as "EJECTING CD" as shown by block 72 to notify the user that the selected slot is being emptied. CD display circles 36(a-f) then continuously light as shown by block 74. The CD display number 37(a-f) corresponding to the selected slot to be emptied then flashes as shown by block 76 as the ejected CD is pushed part way through CD opening 34 and hangs out of the CD opening. CD display number 37(a-f) corresponding to the selected slot then turns off as shown by block 80.
Decision block 82 then determines if a second time period has expired prior to the user removing the CD from CD opening 34. Decision block 82 makes this determination using sensors operable with CD opening 34 (not specifically shown). If the second time out period has expired, meaning that the CD has not been removed from CD opening 34, then the CD is automatically pulled back through the CD opening and pushed onto the selected slot to reload that slot.
