Claims

[Scope of utility model registration request]

A lid body that has a locking part on one side and closes the tape cassette mounting part, a slide base equipped with a magnetic head and a pinch roller and arranged so as to be able to slide freely, and an elastic means that generates rotational force. is biased, and has one end facing the locking portion so that the locking portion can be locked,
It consists of a lock member whose other end faces one end of the slide base so as to be able to come into contact with the one end of the slide base, and the lock member is operated when the slide base is driven with the lid open. A small tape recorder characterized in that the body is rotated to a lockable position, but the lid body is configured to allow a closing operation of the lid body.
