Abstract: An arrangement for mounting a joystick wherein a ball having a spherical portion and a frustoconical portion is mounted in a cylindrical socket within a housing. A cap having a frustoconical surface complementing the frustoconical surface of the ball is mounted on the housing. An O-ring engages the spherical surface of the ball and urges the frustoconical surfaces into engagement. When the joystick is tilted relatively far, the spherical surface of the ball engages the frustoconical surface of the cap and retains the joystick in its tilted position; however, when the joystick is in a near-center position and is released, the frustoconical surfaces on the ball and on the cap are in engagement and cause the ball to snap back to the center position. This provides tactile feedback centering for the joystick.

Thus, it is not necessary to provide accommodation space for other members between the adjacent selecting stationary contact points. Also, it is possible to reduce the spacing interval between adjacent selecting stationary contact points in the arrangement circle, so that the diameter of the arrangement circle can be reduced and the entire lever switch can be reduced in size.

Abstract: A switching device is provided which comprises a casing, a printed wiring board disposed inside the casing, a plurality of fixed contacts formed on the casing, and a plurality of moving contacts for making an electrical connection or disconnection between said plurality of fixed contacts.

Also the plurality of fixed contacts disposed on the casing has such a form of a terminal as to be electrically connectable to motors and a power source as well as to a connector extended to the switching device. Therefore, the number of places to be soldered for electrical connection between many fixed contacts, motors and power source can be reduced.

Abstract: A recess portion 14a is formed in the underside of the flange 14 of a tilting holder 13 at a position corresponding to, for example, an "upper right" select switch 4. As a result, the operating pin 10 of the "upper right" select switch 4 has a fixed gap with the flange 14. Consequently, the operating pin 10 of the "upper right" select switch is pressed when an operating lever 15 is tilted. However, the operating range B of, for example, the "upper right" select switch 4 is set narrower than the operating range A of, for example, the "upper" select switch 4 since the pressing of the operating pin 10 of, for example, the "upper right" select switch 4 is delayed by the gap resulting from the recess portion 14a.

Abstract: A multidirection input apparatus including a housing, a driving member movably positioned within the housing, and an operation member fixedly attached to the driving member and extending from the housing for manual manipulation. The driving body is supported by an elastic member over an input switch. The elastic member includes six protrusions (two rotation protrusions and four tilt protrusions), each protrusion having a movable contact formed on a lower surface of the elastic member, and each movable contact is positioned over an associated fixed contact located on a lower substrate of the housing. Manual rotation of the operation member causes rotation of the driving member which, in turn, presses against one of the two rotation protrusions, thereby causing the movable contact associated with the rotation protrusion to contact its associated fixed contact on the lower substrate.

Abstract: A pressing operation while an operation lever is tilted is inhibited by causing an enlarged portion of the operation lever to butt against a stopper. A tilting operation while an operation lever is pressed is inhibited by causing the enlarged portion to butt against the stopper. Therefore, the two operations can not be concurrently performed so that a set switch and a select switch are inhibited from being simultaneously turned on. Furthermore, the operation lever is supported in a tiltable manner by forming support shafts and rotation shafts whose axes perpendicularly intersect each other. Even when foreign substances are trapped in rotation portions of the support shafts and the rotation shafts, therefore, there is little fear that the foreign substances will remain trapped between the mating or contacting portions, thereby ensuring that the operation lever can be tilted smoothly and returned to the neutral position.

Abstract: A tilt and telescopic switch 10 includes a main body 19 received and accommodated in the space defined by a first hemispherical recess 38 of an upper casing member 12 and a second hemispherical recess 60 of a lower casing member 14. The main body 19 accommodated in the space continuously receives the pressing force of a spring 44 and allows a first hemispherical member 28 of the main body 19 to come into contact with the first hemispherical recess 38 along the substantially whole surface thereof. The first hemispherical member 28 of the main body 19 is thus guided by the hemispherical inner surface of the first hemispherical recess 38, so that the main body 19 rocks from its neutral position in the direction shown by the double-headed arrow X or in the direction shown by the double-headed arrow Y.

Abstract: A collapsible pointing stick structure is mounted on the top side of the keyboard of a notebook computer and is manually pivotable, about a selected axis parallel to the top side of the keyboard, to controllably reposition a cursor being displayed on the lid portion of the computer. When the computer lid is opened, the top end of the pointing stick structure projects upwardly beyond the top sides of the keyboard key cap members to facilitate its manual engagement and manipulation by the user of the computer. However, in response to closing of the computer lid, the top end of the pointing stick structure is automatically collapsed to an elevation generally aligned with the top sides of the key cap members. Due to the collapsible operation of the pointing stick structure its incorporation into the computer does not require that the vertical thickness of the closed computer be increased. A mechanism prevents the pointing stick structure from collapsing when the lid portion is open.

The device includes an automatic reset function using a pair of sensors respectively installed on the yoke components. The joystick handle can be automatically reset to the zero position of each when the sensors are not aligned with respective light blocking members.
