LIBRARY DEVICE, METHOD OF TAKING OUT DATA CARTRIDGE, AND METHOD OF RECEIVING THE DATA CARTRIDGE

摘要

A cell (300) has at its opening a cartridge lock (306) for locking a data cartridge (100) to hold it within the cell. A picker mechanism (500) has a picker arm (521) and a discharge release section (522) for releasing lock effected by the cartridge lock (306). When the data cartridge (100) becomes inserted into the cell (300), a tapered surface (101) provided on the data cartridge (100) makes the cartridge lock (306) recede up to a position where lock is released. When the data cartridge (100) becomes discharged from the cell (300), at the same time when the picker arm (521) engages with an engagement hole (102), the cartridge lock is released by the discharge release section (522).
