SHEET CARRYING DEVICE AND IMAGE FORMING DEVICE ATTACHED WITH THE SHEET CARRYING DEVICE

摘要

PROBLEM TO BE SOLVED: To accurately detect a rear end position of a sheet material by a sensor even if a rotational position of a carrying passage switching member is switched when the sheet material passes. SOLUTION: The sensor 43 is integrally installed on an upper surface of the carrying passage switching member 34 via a support plate 46 so that the sensor 43 integrally rotates with the carrying passage switching member 34. Thus, even if a switching position of the carrying passage switching member 34 is switched to a switching position rotated in the arrow B direction from a position indicated in Fig. 1 in the middle when the sheet material P passes through the carrying passage switching member 34, a distance between the passing sheet material 1 and the sensor 43 can be kept almost constant. Thus, the rear end position of the sheet material P can be accurately detected by the sensor 43.
