Claims

[Scope of utility model registration request]

(1) It has an opening/closing lid that covers the top surface of the small tape cassette stored with the lid closed, and a locking mechanism that locks the opening/closing lid in the closed lid position, and the tape loading mechanism is operated to load the small tape cassette. The tape is pulled out and a tape path corresponding to the front tape bus of the standard tape cassette is formed to perform magnetic recording and/or recording for the standard tape cassette.
Or, in an adapter for a small tape cassette used in a playback device, a mechanism for releasing the lock of the opening/closing lid in the closed lid position by the locking mechanism in connection with the tape unloading operation of the tape loading mechanism, and the locking mechanism. A small-sized tape cassette adapter comprising a mechanism for opening the opening/closing lid which is unlocked by the mechanism.

(2) The lock release mechanism is configured to operate at a stage before the tape unloading operation of the tape loading mechanism is completed, and the lid opening mechanism opens the lid to an incompletely opened state. An adapter for a small tennip cassette as set forth in claim (1) of the utility model registration, which comprises:
