A keyswitch includes a keyboard base , a guide support member disposed on the keyboard base , a flexible circuit board disposed on both sides of the guide support member on the keyboard base , an elongated key top , and a pressing member for pressing the flexible circuit board toward the keyboard base . The pressing member is disposed on both sides of the guide support member directly beneath the elongated key top near lengthwise ends of the elongated key top . When the elongated key top is pressed down the guide support member and the pressing member are housed within the elongated key top

Keyswitch for keyboard

A data processing device including a keyboard with a key; a lid provided to an edge of the keyboard so as to be pivotable from a closed position, to a predetermined angle, and further to an open position; a key support mechanism movable between a first position for supporting the key in an operation condition and a second position wherein the key is not supported; a follower in connection with the key support mechanism so that the follower and the key support move in association; and a driver connected with the lid so as to operate in association with pivotal movement of the lid, the driver driving the follower only when the lid is pivoted between the closed position and the predetermined angle so that the key support mechanism moves from the first position into the second position when the lid is pivoted open between the closed position to the predetermined angle and the key support mechanism remains in the second position when the lid is pivoted open to the predetermined angle or greater.

Data processing device with a keyboard having pop-up keys

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.

Key switch having elastic portions for facilitating attachment of

A key switch of the invention includes a key top having a face on which various characters are displayed and a back face having an engaging portion, a guide support member having two hinge members and a holder plate. The holder plate is provided with support portions which are elastically moved when pushed down by the lower portion of the guide support member to pinch and support the lower portion, and further the engaging portions of the key top can also pinch and support the upper portion of the guide support member by pushing the upper portion. Accordingly, according to the key switch, the fabrication of the guide support member and the holder plate and the fabrication of the guide support member and the key top can be extremely easily performed, and the operating performance of the key top is improved.
