摘要

The device is for operating a computer mouse and comprises an under arm support, elongated, fixable to a chair back with a movement surface for a computer mouse at its outer end. The mouse conductor (1) comprises an under plate (2) fixable with stirrups (3,4) ot the back of a chair. Alternatively, the mouse conductor can be fixed directly with the stirrups to the chair. Above the under plate is an upper plate (5), which is movable in relation to the under plate. Three ball bearings (6,7,8) are connected with the upper plate, the balls of which can roll over the under plate. At the upper plate outer end is a through recess (9), the contours of which coincide with those of the mouse (10). Between the edges of the recess and the mouse is some clearance space. On the rear side of the mouse on the upper plate is a foam coating (12) lined with leather (13). For the rolling manipulation of the mouse over the under plate the complete upper plate is rolled over the ball bearings along the under plate.
