A mouse for a computer has a small touch panel to realize improved functions. The mouse (40) has a lower case (41) and an upper case (42) that covers an upper part of the lower case. A front part of the upper case has an integrated support. The touch panel is installed on the support, and a key top (43) is fitted to the upper case to fix the touch panel. An instruction is generated according to a finger touching period or the movement of a finger on the touch panel, and the instruction is transmitted to the computer, to thereby realize the improved functions. The touch panel may be divided into sections, and some of the sections may be used as switches, to thereby eliminate click switches from the mouse.

The keyboard includes a rubber sheet fixed on key tops of a set of key-switch devices. The rubber sheet elastically urges the key tops upward so that they are borne away from the base of the key-switch devices. The rubber sheet is arranged so as to cover the key-switch devices from outside. According to the invention, the cost of a keyboard covered with a dustproof and watertight rubber sheet can be reduced.

A push button-type switch device includes a pair of fixed contacts, an operable member to be pushed, an actuating member elastically deformable upon the operable member being pushed, a movable contact which short-circuits the pair of fixed contacts due to elastic deformation of the actuating member, and a limiting part arranged to limit a direction in which the operable member moves and making the operable member move in a fixed orientation. The limiting part includes a pair of link members that engage with each other, one ends of the link members rotatably supported by the base portion, and the other ends thereof slidably supported by the operable member. This produces a good click irrespective of a position where the operable member is operated.

A pointing device including a base part, an operating part supported on the base part in a rockable manner about a fulcrum, a magnet carried on the operating part, a magneto-electro transducer carried on the base part, and an elastic member arranged between the base part and the operating part to elastically push the operating part toward an initial balanced position on the base part. The elastic member is formed as a plate spring provided with a first section engageable with the base part and a second section engageable with the operating part. The second section is integrally joined to the first section and located to extend around the fulcrum. The first section of the plate spring extends annularly around the fulcrum and is fixedly supported on the base part, and the second section extends arcuately along the first section to exert a spring action.

A key switch including a base section, a key top, a pair of link members and a switching mechanism. Each link member is provided, at one end region thereof, with a toothed portion meshable with a toothed portion of another link member in a gearing manner and a pivot axle pivotably joined to the base section, and at another end region, with a slide portion slidably engaged with the key top. The base section includes a support plate and a frame member, the frame member being fixedly attached to the upper surface of the support plate. The frame member is provided with a bearing portion pivotably receiving and supporting the pivot axle of each link member. The first end region of each link member is disposed on a lateral side of the frame member and closely to the upper surface of the support plate.
