A joint (129) includes semicircular plates (131) each integrally formed with a link part (132) having a screw hole (133). The joint (129) couples cover members (107, 117) of a flexible display (102) by means of screws (134) passing through the screw holes (133) and grooves (125, 128) of the cover members (107, 117). The link parts (132) of the semicircular plates (131) are caused to operate in sync with each other to stably perform an opening and closing operation of the cover members (107, 117).

A control part is provided independently from a keyboard and is connected to a first keyboard unit through a jointed-arm. The control part can be placed in substantially the back center of the keyboard through the use of a free turning property of the jointed-arm. A PDA connected to a connector member of the control part can be placed in a position where a keyboard user can view the most easily, with the result that the operationality of the keyboard can be enhanced.

A key switch device includes a key top whose position can be selectively changed to operative position or non operating position. In the operative position, the key top can be moved downwardly and upwardly by biasing force of a rubber spring. The key top is supported on a support plate by first and second link members pivotally connected to each other. A pivot connecting portion of the first and second link members is seated on the rubber spring when the key top is in its operative position. The rubber spring is fixed to a circuit board which is slidable with respect to the support plate. By sliding the circuit board, the position of the rubber spring is offset from the pivot connecting portion, so that the first and second link members can be folded up. The first and second link members are directly supported by the support plate.
摘要:
A key switch wherein a switching action is effected by movements of a keytop movably connected to a holder via a scissors-type support linkage which consists of first and second links connected pivotally about a common primary pivot shaft. The keytop, holder and first and second links include at least one special secondary pivot shaft each carried by a special support portion, and at least one special bearing portion each engaging the corresponding special secondary pivot shaft. The special support portion and/or the corresponding special bearing portion has/have an elastic portion which elastically yields to allow engagement of the special pivot shaft and the special bearing portion during assembling of the keytop, support linkage and holder.

A conductor pattern surface of a plastically deformable substrate of a key switch device is insulated with a resist, and a switching circuit pattern is printed on the resist layer by using conductive ink. Carbon conductor ink is applied by printing on connectors and fixed contact patterns, and a mask is printed on the other portion. Mounting portions for mounting a guide supporting member are formed on the substrate by pressing the substrate from the lower surface thereof. An object of the invention is to integrate an electrical circuit pattern with a mounting portion of actuator structure so as to provide a key switch device which can reduce the thickness and the number of parts of a keyboard for a word processor, personal computer or any other device having a keyboard or keypad.

A first key unit in a first keyboard unit is mounted on a first base plate so that the first key unit is turnable, while a second key unit in a second keyboard unit 4 is mounted on a second base plate so that the second key unit is turnable. A gear teeth part formed in a circular arc face of a first gear member placed in one side of a first support plate is engaged with a gear teeth part formed in a circular arc face of a second gear member placed in one side of a second support plate.

A foldable keyboard includes first, second, and third keyboard units U1, U2, and U3 which are rotatably connected with one another by means of main links (4) and (5) disposed on side end surfaces of each unit. The first and second units U1 and U2 are rotatably connected by means of an auxiliary link (6) parallel to the main link (4), and the second and third units U2 and U3 are rotatably connected by means of an auxiliary link (7) parallel to the main link (4). The first unit U1 is formed with recesses (38) at four corners of a peripheral wall member (12) and the second unit U2 is formed with projections (36) at four corners of an undersurface of the second unit U2 so that the projections (36) are received in the recesses (38) when the first, second, and third units U1, U2, and U3 are disposed (stacked) one upon another into a folded state.

A keyswitch device is provided in which a key top is kept at an operation position when a key operation is carried out and is locked at a non-operation position lower than the operation position, thereby keeping high key operation performance while reducing the thickness and thus improving its portability. In this keyswitch device, the key top 2 is disposed to be movably upward and downward on a holder member 4 through a guide member 3, which supports a first link member 10 and a second link member 11 to be mutually rotatable. A circuit board 6 is fixed to a rubber spring 5 on which a base portion 12 of the first link member 10 of the guide member 3 is mounted is designed to be slidable on a support plate 7 in the opening and closing direction of the first link member 10 and the second link member 11 between the operation position and the non-operation position of the key top 2 through an operation knob 27. With this construction, thinning of the keyswitch device 1 can be accomplished. When the keyswitch device 1 is carried, the circuit board 6 is slid to the non-operation position to shift the rubber spring 5 to the non-operation position where it is separated from the guide member 3. Thereby, the guide member 3 is released from being biased by the rubber spring 5, and the first link member 10 and the second link member 11 are folded, so that the height of the key top 2 can be reduced.
