Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a joystick device used in a game device using a microcomputer.

[Background technology and its problems]

The joy stick device generates a signal corresponding to the operation of the stick section by selectively turning on a detection switch depending on the direction of the operation of the stick section. The conventional joy stick device has a protrusion provided at the base of the stick part that comes into contact with the pressing part of the detection switch.
It was designed to stop the operation of the stay section. Therefore, all the force applied during operation is applied to the detection switch, resulting in a shortened lifespan due to failure of the detection switch.

Therefore, a structure has been considered in which the base of the stick part is brought into contact with a part of the case to stop the movement of the stick part. However, since the detection switch is installed on the wiring board, if the case bends, the positional relationship between the case and the wiring board changes, causing excessive operating force to be applied to the detection switch, or causing the detection switch to malfunction. There was a fear that it would not be possible to do so reliably.

[Purpose of invention]

Therefore, an object of this invention is to provide a joystick device that prevents excessive operating force from being applied to the detection switch, has excellent durability, and ensures reliable operation of the detection switch.

[Summary of the idea]

This idea consists of a wiring board housed in a case, a plurality of detection switches attached to the wiring board, and a stay part protruding from the case.
It has a hemispherical base formed integrally with the stick part, and a protrusion provided inwardly on the periphery of the base corresponding to each of the plurality of detection switches, and the stick part can be tilted to a predetermined angle. When the stick part is tilted to an angle exceeding a predetermined angle, the detection switch corresponding to the direction of operation is selectively turned on by the protrusion among the plurality of detection switches. It is a joystick device that is brought into contact with the
The wiring board is used to stop the operation of the stick section.

〔Example〕

An embodiment of this invention will be described below with reference to the drawings.

FIG. 1 is a longitudinal sectional view of an embodiment of this invention, and 1 indicates a case, which is formed by combining an upper case 2 and a lower case 3 made of synthetic resin. The front end of the case 1 is opened, and a smoke plate 4 is attached to this opening, as also shown in FIG. This embodiment is a wireless joystick device, in which an infrared remote control signal modulated by a control signal is sent through a smoke plate 4 to a receiver.

A stake portion 5 is installed through a circular opening formed approximately in the center of the upper surface of the case 1. The rear upper surface of the case 1 serves as an operation receiver 6 on which a hand is placed during operation. A battery storage section 7 is provided below this operation receiving section 6. As the lower case 3 is bent upward, the battery cover 8
is slidably attached, and three AA batteries, for example, can be accommodated in the battery storage section 7.

Reference numeral 9 indicates a wiring board provided within the case 1. The wiring board 9 is screwed to the lower case 3 while being placed on ribs 10 that are integrally raised from the bottom of the lower case 3. Wiring board 9
As shown in FIG. 2, four detection switches 11, 12,
13 and 14 are attached. Further, operation switches 15 and 16 are provided symmetrically on both sides of the wiring board 9, and a slide switch 17 is provided adjacent to one of the operation switches 15. Further, an operating switch 18 is provided on the wiring board 9 at a position sandwiched between the operating switches 15 and 16.

The operation knobs 19, 20, 21 of these operation switches 15, 16, 18 and the operation knob 22 of the slide switch 17 protrude from the outside of the case 1, as shown in FIG. Operation knob 19, 20,
21 is a trigger button. Slide switch 1
7 is for switching when two wireless joystick devices are used at the same time. Furthermore, a pair of infrared light emitting diodes 23 and 24 are attached to the front end of the wiring board 9.

The stick portion 5 is made of a synthetic resin having excellent impact resistance, such as ABS, and has a hemispherical base portion 25 integrally molded with the stick portion 5, and a rubber cap 26 is fitted to the tip thereof. A bowl-shaped control disk 27 is fixed to the base 25 in the base 25 via a member 28 .
The control disk 27 is a molded product made of elastic synthetic resin. control disk 27
Four protrusions 29 project downward from the sensor, and each of the protrusions 29 is positioned above and close to the detection switches 11-14.

A fulcrum shaft 30 having a hemispherical tip protrudes from the center of the control disk 27 in the vertical direction. On the other hand, a fulcrum boss 31 projects from the bottom of the case 1 integrally with the lower case 3, and a recess is formed at the tip of the fulcrum boss 31. The base 25 and the control disk 27 are inserted into the case 1 through the opening of the upper case 2 in a fixed state, and the tip of the shaft 30 is opposed to the recess of the fulcrum boss 31. In this case, a coil spring 32 is compressed between the fulcrum boss 31 and the control disk 27, and the biasing force of the coil spring 32 slightly lifts the control disk 27 to a position where it comes into contact with the upper case 2.

A plurality of guide pins 33 protrude outward from the peripheral edge of the base 25, and guide ribs 34 of the upper case 2
This guide pin 33 is locked to. These guide pins 33 and guide ribs 34 restrict the position of the projections 29 of the control disk 27 so that they approach each of the detection switches 11-14.

As shown in FIG. 1, the base 25 is
and the controller disk 27 is the coil spring 3
2, and a gap of, for example, 1 mm exists between the protrusion 29 and the pressing portions of the detection switches 11 to 14. When the stick section 5 is operated, the base section 25 and the control disk 27 move downward, and a detection switch located in the direction in which the stick section 5 is tilted is turned on.
In this embodiment, four detection switches 11-1
The structure is such that eight directions at intervals of 45 degrees can be detected by turning on one of the four or two adjacent ones.

In this embodiment, when the stay section 5 is tilted by 2°30' from the neutral state, the detection switch corresponding to that direction is turned on, and the stay section 5 is tilted by 2°30'.
If the stick part 5 is tilted any further, the outer circumferential rib 35 of the base part 25 will come into contact with the wiring board 9, and the movement of the stick part 5 will be blocked.

The detection switches 11 to 14 are turned on with a stroke of 0.3 mm, but in order to ensure that they are turned on, it is preferable to use a slightly overstroke.

FIG. 4 shows the appearance of a receiver for receiving remote control signals sent from the wireless joystick device described above.

41 indicates the receiver case and 42 indicates case 4.
1 shows the smoke plate provided on the front side of 43,
44 indicates a fixing suction cup provided on the bottom surface of the case 41. A photodiode for receiving a remote control signal, a demodulation circuit, etc. are housed in the case 41. Cable 4 led out from the rear of case 41
Connectors 46A and 46B are attached to the tips of the connectors 5. Connectors 46A and 46B are connected to connectors of a microcomputer. Operation signals from each of the two wireless joystick devices are taken out from the two connectors 46A, 46B.

In the wireless joystick device according to this embodiment, since the battery storage section 7 is provided in the front, the center of gravity is slightly rearward, and as shown in FIG. 5, the center of gravity is supported by the palm of the left hand. The right hand is placed on the operation receiving part 6 of the case 1, and the stick part 5 is operated by holding the rubber cap 26 at the tip of the stick part 5 with the thumb and forefinger, as shown in FIG. 6A. Furthermore, since the stroke is short and the rubber cap 26 is fixed, it can also be operated with only the thumb, as shown in FIG. 6B.

[Effect of idea]

In this invention, when the stick section is further tilted after the detection switch is turned on, the outer circumferential rib of the base comes into contact with the wiring board, preventing movement of the stick section. Therefore, according to this invention, it is possible to prevent excessive operating force from being applied to the detection switch. However, since the movement of the stick section is stopped by the wiring board, the positional relationship between the base and the protrusion does not change even if the case is bent or otherwise deformed, and a highly durable joystick device can be constructed.
