Abstract: A vibration-generating device having a weight that is formed semicircular in section and has a recess near an insertion hole of a shaft. The weight, after being inserted onto the shaft, is supported in an inclined position by a support member. A pressing member applies a pressure to the recess. Preferably, the pressure is offset from the rotational axis of the shaft.

Abstract: An input device for a game machine for inputting signals to a game machine using a computer, including: at least one control member projecting to the outside of a casing; a movement-transmitting member formed around the control member and operatively associated with the movement of an operating point of the control member, the movement-transmitting member being provided with a plurality of conductive elastic members; and a board provided in the casing and having formed thereon resistors corresponding to the conductive elastic members, the conductive elastic members changing the area of contact between the conductive elastic members and the resistors according to a direction of movement and a tilt angle of the operating point of the control member so as to vary the amount of resistance; wherein, by moving the operating point of the control member, analog signals corresponding to the movement are input to the game machine.

Abstract: In an operating unit, push buttons are integrally formed via a connecting section, and the top face of the connecting section abuts the bottom face of a panel. On side-faces of the push buttons, an outwardly protruding flange is integrally formed. The top face of the flange is set to be at a position higher than that of the top face of the connecting section. When one of the push buttons is pressed down, the operating unit is rotated about a point in the inside of another of the push buttons as a fulcrum so as to turn on the output of a switch member. Because the operating unit is rotated about the inside point as the fulcrum, other switch members cannot be switched.

Abstract: A first resistive element and a second resistive element are serially connected to each other, and a contact element having a lower resistivity than the first resistive element elastically contacts the first resistive element. The resistance between both ends of the first resistive element varies with the contact area between the first resistive element and the contact element. When a predetermined voltage is applied to the first and the second resistive elements, an output voltage, which corresponds to the resistance ratio of the first resistive element to the second resistive element, is obtained from a conductive pattern. When the resistance ratio of the first resistive element to the second resistive element is set in the range of 1 to 3, the linearity is improved and a wide variation range of the output voltage is obtained.

Abstract: A vibration generating device having a weight which is formed semicircular in section and provided with a recess in the vicinity of an insertion hole of a shaft. The weight, after insertion on the shaft, is supported in an inclined position on a support block. Then, a tapered pressing member is moved downwardly to apply the pressure to the recess. In this case, the direction of pressure application of the pressing member is deviated from the axis of the shaft.
