<p>PROBLEM TO BE SOLVED: To supply an electric power signal and/or a control signal without interrupting the motion of a cartridge loading/unloading device by recovering the specific cartridge in accordance with a wireless signal receiver by a communication device and moving it to another place and also transmitting a control signal. SOLUTION: A conical device 211 is positioned such as always visible from the optical communication device even though the cartridge loading/unloading device 36 is moved around the U-shaped route. Since the conical device 211 is installed at the lower surface of the cartridge loading/unloading device 36 and constituted of the reflective material, each optical signal transmitted from the optical communication device is reflected independently of the position of the cartridge loading/unloading device along the U-shaped route. Then, each optical signal transmitted from the optical communication device is reflected to the receiver part of the optical communication device. Meanwhile, the surface of the conical device 211 opposite to a pinion driving assembly 52 each other does not oppositely face direct to the optical communication device, even in any of the positions along the U-shaped route.</p> |
