Abstract

PROBLEM TO BE SOLVED: To stabilize operability in a joystick and also improve its quality. SOLUTION: A button pressing part 46 (47) is provided so as to be turned while being interlocked with a rotary panel 35 of an X-axis rotary encoder 31 and a rotary panel 36 of a Y-axis rotary encoder 32 of a joystick 20 for outputting an analog coordinate signal by detecting the tilt angle of a manipulating stick 25 through the X-axis rotary encoder 31 and the Y-axis rotary encoder 32. When the tilt angle of the manipulating stick 25 reaches a maximum value, switches 48 and 49 are pressed by the button pressing part 46 (47) and a count value similar to that analog coordinate is converted to a digital signal and outputted by that pressing so that the movement control of characters or the like in a computer game is enabled.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joystick, and more particularly, to a joystick with improved stability in controlling the transfer of characters and the like.

[0002]

2. Description of the Related Art A conventional joystick will be described with reference to FIG.

In FIG. 1, reference numeral 1 denotes a joystick. The joystick 1 covers a top surface of a base frame 2 with a cover 3. A central portion of the cover 3 is concavely formed in a circular mortar shape, and a spherical bearing portion 5 is formed at a central portion of the concave portion 4.

[0004] Further, the spherical portion 7 of the operation stick 6 is fitted to the spherical bearing portion 5, and the operation stick 6 is rotatably pivoted. On the other hand, a small-diameter portion 8 protrudes downward from the spherical portion of the operation stick 6, and the small-diameter portion 8 is inserted into a crank mechanism 9 disposed below the operation stick 6.

[0005] The sector gears 10 and 11 rotate in conjunction with the inclination of the operation stick 6 via the crank mechanism 9, and the X-axis rotary encoder 12 and Y-axis rotary encoder 13
(Not shown) rotates. The amount of rotation of the turntable is detected by a photo sensor (not shown), and the detected measurement value is converted into an analog coordinate control signal and output.
Then, it is configured to be able to control the transfer of characters and the like in the computer game.

[0006]

The above-mentioned conventional joystick is configured so that the tilting and tilting of the operation stick is detected by an X-axis rotary encoder and a Y-axis rotary encoder and output as an analog signal.

However, since the joystick outputs the tilt of the operation stick as an analog signal, when controlling the transfer of a character or the like with the joystick,
When the operation stick is tilted to the maximum, a minute movement of the operation stick may be detected and the maximum value may not be output. Therefore, the operation of the character becomes unstable, causing a problem in quality.

Therefore, when the operation stick of the joystick is tilted to the maximum, the maximum value is reliably detected to control the transfer of characters and the like, and the operation is improved in order to stabilize the operation of the joystick and improve the quality. A technical problem to be solved arises, and an object of the present invention is to solve the problem.

[0009]

SUMMARY OF THE INVENTION The present invention has been proposed in order to achieve the above object, and detects the inclination angle of an X-axis by detecting the inclination angle of an operation stick erected at a central portion of a main body. A joystick that detects an X-axis rotary encoder and a Y-axis rotary encoder that detects a tilt angle of the Y-axis, converts an analog tilt angle detected by each rotary encoder into an analog coordinate control signal, and outputs the analog coordinate control signal. A button pressing portion is provided that rotates in conjunction with the rotary disk of the rotary encoder and the rotary disk of the Y-axis rotary encoder. When the tilt angle of the operation stick reaches a maximum value, the button pressing portion presses the switch. In order to provide a joystick capable of controlling the transfer of characters and the like by outputting a count value similar to the analog coordinates by a digital signal by the pressing, Is shall.

[0025]

According to the present invention, as described in the above embodiment, when the tilt angle of the joystick is tilted to the maximum, the button pressing portion connected to the rotary disk of the rotary encoder presses the switch. While reliably recognizing that the slope is at a maximum value, the output of the joystick is converted from analog to digital.

Therefore, it is possible to prevent the maximum output value from being output in an unstable manner as in the prior art, and to reliably control the transfer of the characters in the computer game, thereby stabilizing the operation of the joystick and improving the quality. It is an invention that has a remarkably significant effect, for example, it can be improved.
