Abstract

In order to perform a stable key inputting operation even if the keyboard device is installed at an inclined surface, a rear surface of a main body is formed with a notch, and the notch is provided with an adjuster member. A turning centerline of the adjuster member is in an inclined angle in respect to the rear surface. The notch has a depth size from the rear surface at the rotatable supporting side of the adjuster member deeper and its depth size becomes smaller as it is farther from the rotatable supporting side. The adjuster member is turned to cause the adjuster member to be changed over between one attitude in which it is protruded out of the notch and the other attitude in which it is stored in the notch. In addition, the adjuster member is formed with a shaft, there is provided a resilient member for resiliently pressing the outer circumference of the shaft and the resilient member is fitted to a sliding notch formed at the outer circumference of the shaft.

Dependent claims

A keyboard device in which an adjuster member arranged at a rear surface of a main body having operation keys at a front surface and installed to be freely protruded from the rear surface is installed and a mounting attitude of the main body is set to a predetermined angle when said adjuster member is protruded, wherein

the rear surface of the main body is formed with a notch;
the adjuster member is rotatably supported in the notch;
the adjuster member can be turned between one attitude in which the adjuster member is stored in the notch and another attitude in which the adjuster member is protruded out of the rear surface,
a turning centerline of the adjuster member is extended from within the notch toward an opening side of the notch at an angle inclined against the rear surface of the main body,
one end of the adjuster member in a longitudinal direction of the adjuster member is a supporting side rotatably supported and an other end of the adjuster member in the longitudinal direction is a protruding end protruded out of the notch when the adjuster member is turned, and
the turning centerline of a turning operation is positioned at the one end side and crossed with a direction extending from the one end to the other end.
