Description
Background of the Invention
1. Field of the Invention
The present invention relates to an input device for three-dimensional input to an information processing device, particularly a multi-way input device for operating the moving direction, etc. of characters in a television game or the like.
2. Description of the Related Art
FIG. 12 is a sectional view of a conventional multi-way input device. On a substrate 31 there are arranged push-button switches 33 in four directions around a support rod 32. On a top portion 32a of the support rod 32 is mounted an operating lever 34 so as to be tiltable in the four directions in which the push-button switches 33 are arranged. The operating lever 34 has four overhang portions 34a overhanging in the four directions of push-button switches 33.
When the operating lever 34 is tilted about the top portion 32a of the support rod 32, its overhang portion 34a positioned in the inclined direction depresses the push-button switch 33 located in the same direction. In this way it is possible to make input in four directions.
According to the above multi-way input device, however, only a planar operation such as cursor movement can be done by operation in two-axis directions, namely in the right and left direction and the direction perpendicular to the paper surface in FIG. 12, and it has been impossible to make input in three-dimensional directions. There has also been the drawback that the operating portion is difficult to grasp because it is stick-like and that therefore it is difficult to perform a quick operation.
Summary of the Invention
Accordingly, it is the object of the present invention to provide a multi-way input device capable of making input in three-dimensional directions and easy to operate in conformity with the human's operating sense.
In order to achieve the above-mentioned object, in one aspect of the present invention there is provided a multi-way input device including:
an upper housing having a first recess formed in the bottom thereof;
a lower housing having a second recess opposed to the first recess;
an actuator supported rotatably within the first and second recesses and provided with a vertically extending rotatable shaft;
an operating member engaged with the rotatable shaft and adapted to rotate in three-dimensional directions of X, Y and Z axes together with rotation of the actuator;
a first switch for detecting the rotation in the X-axis direction of the operating member;
a second switch for detecting the rotation in the Y-axis direction of the operating member; and
a third switch for detecting the rotation in the Z-axis direction of the operating member.
In the second aspect of the present invention there is provided a multi-way input device characterized in that an actuator is provided rotatably within a housing, an operating member which is interlocked with the actuator is provided rotatably in the directions of X, Y and Z axes, a circuit board is in engagement with the actuator, a plurality of switches are mounted on the circuit board, and the rotations in the X, Y and Z directions of the operating member are detected by the operation of the said switches.
On a substrate there are provided, in addition to first and second switches, a third switch disposed in a direction in which it can be pushed in the surface direction of the substrate, and a slide-contact surface of the actuator is part of a predetermined spherical surface, while the housing interior is provided with a slide-contact surface for sliding contact with the slide-contact surface of the actuator. Therefore, it is possible to perform operation in six three-dimensional directions. Besides, since the operating member has a shape bridging the upper and lower ends of the stick, the device is easy to carry with both hands and it is possible to perform operation matching the human's operating sense.
Further, by providing a fourth switch capable of being pushed axially of a shaft, it is made possible to perform a sliding operation along a uniaxial direction, in addition to the tilting operation in three-axis directions.

As best shown in FIG. 5(a), the upper housing 6 has a stepped portion 6a and a hole 6b, while the lower housing 7 has a stepped portion 7a and a hole 7b. As shown in FIGS. 2 and 5(a), the lower housing 7 includes a recess 7c formed in a top surface thereof, and FIG. 5(a) shows that the upper housing 6 includes a (second) recess 6c formed in a bottom surface thereof, the first recess 6c and the second recess 7c forming a chamber for rotatably receiving the actuator 3.

FIGS. 7(a) and 7(b) are sectional views of FIGS. 6(a) and 6(b), respectively. In the interior of the upper housing, as shown in FIG. 7(b), pushing projections 19a and 19b are formed so as to come into abutment with to-be-pushed portions of the push-button switches 2a and 2b, respectively.

On the substrate 1 are mounted push-button switches 2e and 2f in parallel with the substrate surface, while on the upper housing 6 side there are provided pushing pins 19e and 19f for abutment with to-be-pushed portions of the push-button switches 2e and 2f, respectively. When the operating member 17 is tilted and the actuator 3 rotates as in FIG. 9(b), the push-button switch 2f moves and is pushed by the pushing pin 19f.

FIGS. 11(a) and 11(b) are sectional views of FIGS. 10(a) and 10(b), respectively. In FIG. 11(b), the slide pin 16 moves down through the slide hole 3b with downward movement of the stick 5 and depresses the push-button switch 4a.
Conversely, upon upward operation of the operating member 17 relative to the housing 18, a pusher pin 20 is provided in the lower component 9 of the operating member 17 to push the push-button switch 4b.
Although in this embodiment the push-button switches 4a and 4b are provided on the substrate 1 and actuator 3 side, both switches may be provided on the upper and lower housing 6, 7 side and a member corresponding to the pusher pin 20 may be provided in the actuator 3.
