Title: Disk drive device
Inventor: AOYAMA TAKASHI
IPC: G11B17/043
Filed: 1994-05-12
Abstract: PURPOSE:To prevent a detecting switch from being broken by providing a cassette (DK) corner part entering preventing part in a hole of a cassette guide part on the side of a chassis at an entrance of a DK housing room and narrowing a hole in width on the inserting side. CONSTITUTION:The detecting switch SW and a cassette holder 10 are disposed on a main chassis 3a to constitute the DK housing room 19. One pair of cassette guides 20a and 20b on the right and left are provided on the chassis 3a at the entrance of the housing room, and a guide 20a on one side is provided with the hole 21 to allow the detecting switch SW to enter this hole. Then, the hole 21 on the cassette inserting side is narrowed in width to prevent entering of a corner part 1a of the DK. By this constitution, when the DK is inserted under the standing state of the corner part, the corner part of the DK are not inserted into the hole due to the entering preventing part or the narrowed width of the hole 21 on the inserting side, and hence a detecting rod of the detecting switch SW is not damaged by the corner part of the DK.
