Title: Shutter opening/closing mechanism for recording medium driving device
Inventor: KURITA SATOSHI
IPC: G11B17/043
Filed: 2000-11-20
Abstract: PROBLEM TO BE SOLVED: To provide a stutter opening/closing mechanism of a recording medium driving device, which prevents the deformation of an opening/closing member constituted of a flat spring and realizes a stable opening/closing operation. SOLUTION: A restriction part 6d is arranged in a holding member 6 reciprocating a cartridge case 2 between a standby position and a play position in a holder 5. The flat spring (closing member) 7 having a projection part 7a is fixed to the outer face of the holder 5 in a cantilever shape and the restriction part 6d is brought into contact with and is detached from the projection part 7a of the leaf spring 7 with the movement of the holding member 6. At the time of inserting the cartridge case 2, the projecting part 7a is made abut on the restriction part 6d and it is bent outward. The projecting part 7a can be press-contacted to the side of the opening/closing shutter without making the projecting part 7a pass through the guide groove 2b of the cartridge case 2.  Thus, the projecting part 7a is prevented from being caught by the inner wall of the guide groove 2b and from being deformed and the stable opening/ closing operation of the opening/closing shutter 3 can be realized.
