SHUTTER OPENING/CLOSING MECHANISM AND INFORMATION REGENERATIVE DEVICE

摘要

A shutter opening/closing mechanism capable of automatically opening/closing a shutter by inserting a cartridge and preventing noise and rattling from occurring in loading and unloading the cartridge. The shutter opening/closing mechanism comprises a driven body (18) engaged, at the opening part (11) of the cartridge, with a part of a drive body (13) opening/closing the shutter (15) installed in the cartridge (10) by driving in the cartridge (10) and a cam mechanism (7, 7a) restricting the movement of the driven body (18) so that the contact of the driven body (18) with the opening part (11) of the cartridge (10) can be avoided when the engagement of the driven body (18) with the part of the drive body (13) is released.
