Further, as shown in No. 3 of TABLE V, after either of the function keys such as the product key ".times." and the division key ".div." is operated, the input of a numeral enables the symbol of "K cal" to be erased.
FIG. 3 is a block diagram of the calorie calculator of FIG. 1.
The circuit of this calorie calculator comprises two Large Scale Integrated Circuits (LSIs). A central processing unit (CPU) 40 is a single chip microprocessor of 4 bits. This CPU 40 is provided for storing a system program, the menu item data, and the calorie data. The CPU 40 serves to control the display and key input. A display 20 relates to the display 2 of FIG. 1. A driver 21 is provided for driving the display 20.
FIG. 4 is a flow chart of the algorithm of the calorie calculation mode.
The first data as the calorie data are stored into an X register. After one of the four function keys for the four fundamental rules of the arithmetics is operated and before the second data of the calorie data are inputted, the contents of the X register are forwarded into a Y register. The second data are loaded into the X register. To obtain the calculation results, the results which are obtained by adding the contents of the Y register to the contents of the X register (or, either of subtracting, producting, and dividing) are forwarded into the X register.
With reference to FIG. 4, the calorie calculation mode is conducted by storing, in place of the first numeral data, the calorie data equivalent to the menu item retrieved by the menu item name searching operation.
Steps n1 and n2: Upon inputting the key operation of the keyboard 3, the type of the operated key is detected to detect whether it is the menu item retrieval keys 32 through 34 or not.
Step n3: In accordance with the type of the operated key, the name of the menu item and its corresponding calorie data are inputted into the X register.
In connection with the retrieval or search operation of the menu items, the operations in steps n1 through n7 are equal to the input of operated values in the four fundamental rules of the arithmetics or the input in the numeral in the arithmetic calculation mode with a memory.
Step n5: This step is executed to directly input the numeral by key input operation rather than inputting the numeral by the menu retrieval.
Steps n10 and n11: These are executed to input an operation value.
Steps n12 and n13: These are executed to detect whether to operate the equal key 37 =" and the corresponding calculation.
Steps n2 through n7: These are executed to input the first data in the calorie calculation mode.
Steps n10 through n13: These are executed to input the second data in the calorie calculation mode.
Step n6: This is selected to store the character data pattern in the CPU. The character pattern is displayed.
Step n11: This is selected to add the symbol of "K cal" after the addition key "+" or the subtraction key "-" is operated.
FIG. 5 is a flow chart showing the operation of the memory in the arithmetic calculation mode and the calorie calculation mode.
Step S5: Because the different memories are used depending on the type of the arithmetic calculation mode and the calorie calculation mode, either memory cannot be destroyed even when the mode switching and the memory contents are enabled.
FIG. 6 is a schematic illustration of retrieving the menu item name using the CPU 40.
The CPU 40 comprises an address pointer 401, a menu address table 402 composed of a read only memory (ROM), a read only memory (ROM) 403 for storing the menu and the corresponding calorie data, and random access memory (RAM) 404 for storing address data, and a character generator 405.
The menu items are retrieved as related to the numerals representative of retrieval procedures in FIG. 6 as follows:
.circle.1 Upon the operation of the menu item retrieval keys 32 through 34, the data in the address table 402 directed by the relating address pointer 401 are loaded into the RAM 404.
.circle.2 Because the location of the RAM 403 equivalent to the address data stored in the RAM 404 contains the menu item data, the menu item data are written-in from the RAM 403 to the RAM 404.
.circle.3 Because the data stored in the RAM 404 are represented in the respective character data, the character data are translated into the corresponding display patterns with reference to the character generator 405. The display patterns are forwarded into the driver 21.
According to the calorie calculator of the present invention, the calorie data of the retrieved menu items can be summed up in the memory. The calorie data retrieved by the operation of the menu item retrieval keys 32 through 34 are summed up in the memory by operating the "CALORIE" key 35. The total data can be retrieved and displayed by operating the key 37 once. The contents of the memory can be canceled by operating the key 37 twice in succession. Because the calorie calculation mode is independent on the arithmetic calculation mode, two memories are peculiar to the two modes. Even when either memory is used in either of the two calculation modes, the contents of the other memory for the other calculation mode are unchanged.
In response to the key input of the numeral after the actuation of the product key ".times." and the division key ".div.", the symbol of "K cal" is erased while the numeral input after the actuation of the addition key "+" and the subtraction key "-" enables the illumination of the symbol of "K cal" as shown in FIG. 4.
It may be further possible that it is announced automatically whether the contents of the memory exceed a predetermined value or not. In the flow chart of FIG. 4, in steps n7 and n8, in response to the actuation of the key 36 "M+", the sum of the calorie data are transferred into the memory in step n8. The contents of the memory are compared with the predetermined value. Depending on the results of the comparison, it can be announced that the sum of the calorie data exceeds the predetermined value. An announcement means for this purpose comprises a display or an voice synthesizer.
As described above, according to the present invention, the calorie memory is provided for storing a plurality of menu items, particular foods and the corresponding calorie data. The calorie data relating to the menu items and the particular foods can be retrieved.
While only certain embodiments of the present invention have been described, it will be apparent to those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of the present invention as claimed.
