PURPOSE: To simplify the mechanism and reduce the cost by interlocking the rotary edge shaft of a recording paper cutter of a facsimile or the like and a paper discharge roller shaft and providing an invalid portion corresponding to the rotation angle from the standby position of a rotary edge to the cutting completion.

CONSTITUTION: A motor is rotated via a cutting command, a rotary edge 4a is rotated by an angle α, and the recording paper 2 is cut, In this case, a discharge roller shaft 8 is rotated at a double speed via a gear train. Therefore,a discharge roller 5 is rotated by an angle β twice as much as the angle α, a notched end 5a reaches a position 5b, and the recording paper 2 starts to be fed to the discharge direction via the friction force of a circular arc section 5c. The distance via the friction force of a circular arc section 5c. The distance L between the cutting position 4b and position 5c is made less than the double length of the circumferential length of the circular arc section 5c, thus the recording paper is discharged. When the rotary edge 4a is rotated once, the motor is stopped via a detection signal and is held at this position by an action of a one-turn control member. Accordingly, the structure is simplified and the cost can be reduced.
