RECORDING MEDIUM CUTTER

摘要

A recording medium cutter of which the cutting blade can be moved between two positions, a cutting position and a noncutting position, in a short time and which can accurately cut a recording medium. A main body (40) rotatably holding a rotary blade (32) and a driven blade (34) is positioned between the side plates (36 and 38) of the cutter (30). A main shaft (39) which is the rotating center of the blade (32) is rotatably provided between the side plates (36 and 38) and the main shaft (39) is also the rotary shaft of the main body (40). A driving motor (44) is fixed to the fitting plate (42) of the side plate (36). When the main shaft (39) is rotated by the motor (44), the blade (32) rotates, and hence the driven blade (34) pressed toward the side face of the blade (32) rotates around the shaft (39). As a result, the main body (40) also rotates round the shaft (39). When the main body (40) is moved to the cutting position from a noncutting position, the rotation of the main body (40) is stopped the moment that the stopper (41) of the main body (40) comes into contact with a stopping plate (50), while the blade (32) continuously rotates. When the main body (40) is moved to a noncutting position from the cutting position, the rotation of the main body (40) is stopped the moment that the lever (58) which is engaged with the main body (40) at the rotating time comes into contact with the hole end section (38a) of the side plate (38). When the lever (58) comes into contact with the hole end section (38a), the driving motor (44) is turned off, because the sensor bar (60) of the lever (58) turns off a sensor (62).
