Abstract
Abstract A copy stand for shifting a cursor by a motor one line on a copy at a time in which a cursor holder is coupled to bend slightly and sandwich an endless belt driven by the motor. At the driving time by the motor, a coupling force works strongly by a tension of the belt to shift the cursor by the motor and when the cursor is to be returned to its upper end, the cursor can be easily shifted manually while the belt is stopped.
