Abstract
One end of a keyboard is raised or lowered for easy keying operation. By turning knobs on both sides of a keyboard, an inclination of the board can be arbitrarily adjusted as required for an operator. Additional plugs or connecting parts are not required to connect the keyboard to a data processing unit and set it in position. The keyboard can be engaged with the data processing unit by inserting a pair of leg members, each of which is respectively constructed in one unit to detachably connect the keyboard into slots of the data processing unit.

11. In combination with a data processing unit having a keyboard detachably and tiltably mounted on a body of said data processing unit, a tilt device of said keyboard comprising:
-
recesses formed at both rear corners of said keyboard; a tilting member supported in each of said recesses rotatably around and movably along a shaft attached to said keyboard and having a leg piece projectable from a base surface of said keyboard when said tilting member rotates; a resilient member activating said tilting member in the direction of said shaft, said resilient member attached at one end thereof to said tilting member and at another end thereof to said keyboard; and lock means for locking rotation of said tilting member around said shaft at a predetermined position by engaging two locking members with each other when said tilting member rotates, one of said two locking members being attached to said tilting member and the other attached to said shaft.
