PURPOSE:To reduce the size of a controller by supplying a drive current to a motor which is to be driven next through a switch for detecting the moving ends of a plurality of articles. CONSTITUTION:When a pushbutton switch 115 is closed in the state a tray 2 is conveyed so that that switches 16, 18, are ON and switches 17, 19 are OFF, a current flowed in a path of the output terminal OUT7 of a driver 22, a motor 24 and an output 8, and the tray 2 starts moving to convey in a direction of an arrow A. Thus, the switch 16 is opened. When the tray 2 arrives at the moving end, switch 17 is closed, a motor 25 is normally rotated, and a clamper 3 starts moving down in a direction of an arrow C. Thus, the switch 18 is opened. When the clamper 3 arrives at the moving end, the switch 19 is closed. A controller 21 detects it to stop the output of the driver 22. |
