PURPOSE:To automatically collect a foreign matter which drops between a device main body and a unit. CONSTITUTION:The unit 30 is moved in a direction shown by an arrow A to be adjacent to the device main body 10. A gutter member 51 existing at a receiving position where the dropping foreign matter B is received inclines backward and exist at a discharge position K2, and discharges the foreign matter B to a guiding member 52 existing a receiving position. One end of the member 52 is pressed upward by a tension spring 52e and connected to the unit 30 through a wire 52h. When the unit 30 is separated from the device main body 10, the member 52 is inclined by a wire 52e and takes a collecting position, so that the foreign matter B is guided to a collecting member. At such a time, the member 51 is restored to a bearing position and receives the foreign matter B dropping from the above. Thus, since the members 51 and 52 properly change the positions corresponding to the movement of the unit 30, the foreign matter B is automatically collected in the collecting member. |
