发明名称 Disk cartridge and optical disk read/write device
摘要 A disk cartridge includes: a lever engagement recess for engaging with a shutter lock engagement bump of a shutter near a side face of the optical disk read/write device; a lever section which rotates around a rotation support point which is located closer to a middle front part of the cartridge in terms of the insertion direction than is the lever engagement recess; and a pressing spring, rooted at the lever section, opposite to the lever engagement recess, between the lever engagement recess and the rotation support point to extend towards and past the rotation support point, for pressing the lever section to apply thereto a rotational force in such a direction that the lever section can engage with the shutter. The arrangement keeps small the stress of the spring section of the lock member and offers a disk cartridge in which the spring section can be disposed in small space on a triangular corner of the cartridge.
