A vibration generating device has a vibration generating member that causes vibration in a vibration direction, a vibration transmitting member, and a base body. The vibration generating member has a first yoke and a second yoke spaced in the vibration direction so as to face each other, a coil that generates magnetism, and a support body that supports the first yoke. A first gap is formed between the first vibration-side opposite surface of the first yoke and the second vibration-side opposite surface of the second yoke; these surfaces face each other in the vibration direction. A second gap is formed between the first orthogonal-side opposite surface of the first yoke and the second orthogonal-side opposite surface of the second yoke; these surfaces face each other in an orthogonal direction orthogonal to the vibration direction. The first gap is narrower than the second gap.

Through positioning between a first mark portion of a first substrate body and a second mark portion of a second substrate body, a first connection terminal portion and a second connection terminal portion are superimposed on each other simultaneously with the superimposition of the second substrate body on the first substrate body. In addition, a first substrate cut-off portion and a second substrate cut-off portion are also superimposed on each other. The first connection terminal portion of a first row and the second connection terminal portion of the first row are electrically bonded to each other by thermo-compression bonding or the like.

A key-switch device includes a key-top having retainers formed on the back surface of the key-top, first and second levers disposed under the key-top, each lever including a base-end part and a pair of arms opposing each other and extending from both ends of the base-end part, the first and second levers being connected together rotatably about the substantial center of the pair of arms as an intersecting point, a lever-holding plate capable of retaining each lower end of the first and second levers, and an actuator member attached to and spanned between both the base-end parts of the first and second levers. Further, the actuator member has a concave slide-retainer-receiving part with the open top, and the base-end part of the second lever is slidably retained in the slide-retainer-receiving part.

Key-switch device corresponding to miniaturized notebook-size personal computer with reduced-thickness

A keyswitch including a lever mounting plate with which the bottom ends of a pair of levers can engage, and an actuator with which the top ends of the pair of levers can engage. The lever mounting plate is mounted to a holding plate, and is placed on a membrane switch. The actuator is mounted to the keytop. The lever mounting plate and the actuator each include a rotation engaging section and a slide engaging section. The rotation engaging section has an open portion and allows a rotating pin of one of lever members to rotatably engage therewith. The slide engaging section has an open portion, and allows a slide pin of the other lever member to engage therewith. The open portion of the rotation engaging section and that of the slide engaging section open in the same direction so that the pair of lever members can be mounted to the lever mounting plate and to the actuator by only moving the pair of lever members from one side to the other.

Keyswitch having a keytop that is upwardly and downwardly movable and method of assembling the same

A keyboard device includes a lever-mounting plate which mates with a pair of levers at lower ends thereof and a holding plate for mounting the lever-mounting plate. The lever-mounting plate is provided with a mating unit to mate with the holding plate by snapping. The lever-mounting plate provided with the mating unit can be mounted to the holding plate through one-touch operation, whereby mounting becomes simple and manufacturing processes are easily automated.

A co-ordinates input device having a transparent substrate member is composed of: a transparent substrate; an ITO film formed on a surface of the transparent substrate; a pair of electrodes formed at a given distance from each other on the ITO film; an operation region formed between the pair of electrodes; and lead electrodes, extending from the pair of electrodes, formed on the ITO film; in which at least one of the lead electrodes extending from the pair of electrodes is formed on the ITO film on a side of the operation region, and between the lead electrode and the operation region, a groove is formed in the ITO film alone or in the ITO film and continuously extending into the transparent substrate.

A tablet that hardly causes the fluctuation in the sheet resistance on a film substrate despite the small size of the tablet. The edge of one side of the film substrate requiring a notch for connector insertion are provided with other notches having the same depth as that of the notch for connector insertion, thereby notching most of the edge to the same depth.
