A hand-held game machine (10) includes a horizontally-long rectangular housing (12), and the housing is covered with a cover (14) almost entirely. Each of top main surfaces of the housing and the cover has a plane shape of pincushion, and thus, the top main surface of the housing forms a lower inclined surface (26) connecting a lower side surface (22) and the top main surface of the housing. On the top main surface of the housing, a cross key (16) and an A button (18a), and a B button (18b) are provided, and on the lower inclined surface (26), a start switch (28) and a select switch (30) are arranged. On left and right edges of an upper side surface (20) of the housing, a left switch (32L) and a right switch (32R) are arranged. As to each of the left switch and the right switch, a switch portion is formed at one end nearer to a center of the housing in the horizontal direction, and a pin is provided at the other end opposite thereto. The pin is inserted into a bearing formed on the housing to function as a pivot at the other end of each of the left switch and the right switch.

A gaming device comprises a cabinet with a hinged door, a gaming unit housed within the cabinet for playing a game, and a button panel system. The button panel system includes a printed circuit board mounted to the door and disposed inside the cabinet; a plurality of switches removably mounted to the printed circuit board; a button panel detachably mounted to the door in proximity to the printed circuit board and exposed to a player; a plurality of buttons mounted to the button panel in a preselected arrangement; and a plurality of actuators coupled to the respective buttons and disposed to actuate a group of the plurality of switches in response to pressing the respective buttons, the group of the plurality of switches cooperating with the game played by the gaming unit.

An operating device to be used, for example, as an input portion for a game controller. The operating device comprises a housing, a push button, and a switch base comprising a switch portion and a support base. The housing is provided with a support member for supporting the switch base and is also provided with an anti-dislodgment retaining portion for preventing the push button from coming off to the exterior from the housing. The push button is provided with a retaining lug for engagement with the anti-dislodgment retaining portion of the housing and is also provided with a retaining lug for engagement with the support base in the switch base. The support base is provided with an anti-dislodgment retaining portion for engagement with the retaining lug of the push button and is also provided with a guide portion. With this guide portion, the movement of the push button is guided in its pushing direction and is prevented from wobbling in the vertical direction.

A controller unit for controlling an electronic device such as a video game. The controller unit comprises a housing with a pair of handles diverging toward a user and gripped by the palms of the user, first and second control sections arranged on the top of the housing and each including a plurality of key elements, and third and fourth control sections arranged on the front side of the housing and each including upper and lower key elements. The first control section comprises a key body having a first semispherical recess on its bottom and a second semispherical recess on its top, a spherical fulcrum member located below the key body and engageable with the first recess, a base plate mounted in the housing and including fixed contacts, a resilient body disposed between the key body and the base plate and including movable contacts, and a key support centrally located at the key body and having a semispherical projection engageable with the second recess.
