5 are inserted through the corresponding openings 30 and 30 of the upper housing 21 so as to project to the outside.

FIGS. 2 and 3 show the operation stick support portion 35. In the drawings, reference numeral 37 denotes a case. The case 37 is formed in a box shape.
7, terminals 38 and 39, and variable resistors 64,
65 volume terminals 40, 41, 42 are soldered.

As shown in FIG. 1, both ends of a first shaft (lower shaft) 45 are rotated by a pair of shaft support holes 43 and 44 opened to face left and right side walls 37A and 37B of the case 37. The shaft portions 46 and 47 are fitted and supported, and as shown in FIG. 2, a pair of shaft support holes 48 and 49 formed in the front and rear side walls 37C and 37D of the case 37. Shaft (upper shaft) 5
The rotation shafts 51 and 52 at both ends of the “0” are fitted and supported.

[0010] At the center of the first shaft 45, a concave portion 54 into which the circular lower end 53 of the operation stick 36 is fitted from above is formed by being depressed in the radial direction. A long hole 55 that allows the operation stick 36 to be inserted from the second shaft 50 side to the recessed portion 54 side of the first shaft 45 at the center and allows the operation stick 36 to rotate in the inserted state in the radial direction. And formed through.

The partition walls 54 before and after the concave portion 54
A, a support shaft 56 is fixed to 54B, and the operation stick 3
6 has a pivot hole 57 at the center thereof, which is fitted to the support shaft 56, a width the same as the diameter of the pivot hole 57, and the outer peripheral surface side of the lower end 53 and the pivot hole 57 side. And a concave portion 58 extending in both directions and having both ends opened to the outer peripheral surface and the pivot support hole 57 is provided.

Therefore, when attaching the operation stick 36, the operation stick 36 is inserted into the long hole 55 of the second shaft 45.
After the lower end 53 of the operation stick 36 is inserted into the recess 54 of the first shaft 45,
With the concave portion 58 facing the support shaft 56, the lower end 53 of the operation stick 36 is pushed toward the support shaft 56 in this state, and the pivot hole 5 is formed.
7, the fitting property of the concave portion 58 to the support shaft 56 is deteriorated depending on the position and the orientation of the operation stick 36, and the operation stick 36 after fitting is deteriorated. It is assumed that the concave portion 58 is detached from the support shaft 56 by the rotation.

Therefore, in the present embodiment, as shown in FIG. 4, the left and right partition walls 54C, 54D of the recess 54 are provided.
When the upper side of the operation stick 36 abuts on the upper opening edge 60 and the lower end of the lower end 53 of the operation stick 36 fits into the entrance of the recess 54, the center line O1 of the recess 58 is pivoted. So as to be substantially orthogonal to the 56 axis O2,
The intersection angle θ ₁ between the axis O 3 of the operation stick 36 and the center line O 1 of the recess is determined to enhance the fitting of the lower end of the operation stick 36 to the support shaft 56, and is further concentric with the opening hole 59. When the operation stick 36 contacts the opening 30 formed in the upper surface of the operation stick 36 at the maximum rotation, the lower side of the operation stick 36 and the recess 5
The apertures of the openings 30, 30 are set so that a predetermined gap is set between the left and right partition walls 54C, 54D and the upper opening edges 60 of the partition walls 54C, 54D. The lower end 53 of the operation stick 36 is prevented from coming off.

As shown in FIGS. 2 to 4, a seat plate 63 is provided between the inner bottom surface 61 of the case and the first shaft 45, supported by a return spring (coil spring) 62. As shown in FIG.
Is a variable resistor 6 for detecting the operation angle in the X-axis direction.

Therefore, as shown in FIG. 1, the knob 66 is fitted and fixed to the upper end of the operation stick 36 projecting from the opening 59 and the opening 30, and in this state, the knob 66 is moved by the thumb. When pressed in the front-rear direction (X-axis direction), as shown in FIGS. 1 and 2, the operation stick 36 rotates along the long hole 55 of the second shaft 50, and the first shaft 45 becomes the shaft support hole 43. , 44 as a fulcrum. When the knob 66 is pressed in the left-right direction (Y-axis direction), since the operation stick 36 is in contact with the long hole 55, the operation stick 36 is supported by the shaft support holes 48 and 49 of the case 37 as the fulcrum. The shaft 50 is rotated left and right. Therefore, a signal corresponding to the swing direction of the operation stick 36 is input from the variable resistance machines 64 and 65 to the game machine.

The seat 63 is provided with the operation stick 3.
When the return spring 62 is pressed in accordance with the amount of rotation of the lever 6, the desired resistance is urged against the operation of the operation stick 36. When the downward force is released by the operation of the operation stick 36, The return force of the return spring 62 is urged against the first shaft 45 to press the operation stick 36, thereby returning the operation stick 36 to the approximate center position of the long hole 55.

As shown in FIGS. 1 and 2, the central portions of the first shaft 45 and the second shaft 50 are formed in a crank shape, and the first shaft 45 and the second shaft 50 are connected to the side wall 37 of the case 37.
A to 37D, the axis of the first shaft 45 and the support shaft 5
6 so as to be orthogonal to the axis of the first shaft 45.
When the central portion is used as a spring retainer for the return spring 62, the height of the case 37 can be significantly reduced, and the height of the joystick can be significantly reduced.

Thus, the present invention can be variously modified without departing from the spirit of the present invention, and the present invention naturally extends to the modified one.

[0019]
