Abstract
A hand mechanism and a library apparatus capable of performing cartridge detection at a high speed as well as reducing the production cost. The library apparatus includes an entry/exit mechanism (container shelf) having a plurality of cells (container chambers) for containing a cartridge and a hand mechanism for taking a cartridge out of the entry/exit mechanism. The cells have a reflection plate (reflector), and the hand mechanism has a sensor (cartridge detector) emitting a detection light and receiving the detection light reflected from the reflection plate. The detection light is simultaneously applied to two or more cells.
