Claims

[Scope of utility model registration request]

A tape that has an opening/closing lid that covers the top surface of a stored small tape cassette, and that operates a tape loading mechanism using a built-in motor to pull out the tape from the small tape cassette and is compatible with the front tape path of a standard tape cassette. In an adapter for a small tape cassette used in a magnetic recording and/or reproducing device for a standard tape cassette by forming a path, the opening/closing lid is locked in a closed state in connection with the tape loading operation of the tape loading mechanism. , the tape loading mechanism remains locked until the tape unloading operation is substantially completed;
An automatic lock/unlock mechanism that releases the lock upon completion of the tape unloading operation is provided, and an operating section that is operated when changing the operating direction of the tape loading mechanism during operation, and an operating section of the operating section. A small tape cassette adapter comprising a motor drive circuit that reverses the polarity of the power supply to the motor and reverses the motor by operation.
