<p>PURPOSE:To prevent a defect caused by the pulling of a sheet material and to cope with a wide range of functions of an image recording device by driving a DC motor for driving the conveyance of a sorter by means of a power source with high impedance. CONSTITUTION:Due to a power source with high impedance which is obtained by outputting a pulse having a defined on time at a defined period from an unshown microcomputer, since a current which flows in a DC motor M for the conveyance of a sorter S is small at a low load, the voltage of the motor M becomes high causing a high speed rotation. When the convayance of a sheet material 1 is started, the load becomes high lowering the voltage of the motor M, and the conveying speed of the copying machine body C is followed. Thus, by controlling the DC motor M, the sheet material 1 can be securely received from a copying machine body C by utilizing the difference in the sheet conveying speeds between the copying machine body C and the sorter S.</p> |
