Loading device for a cassette tape recorder

摘要

A loading device for a magnetic cassette tape recorder includes a ring gear to load and unload a magnetic tape from a tape cassette onto a drum. A guide rail including a fixing groove on the guide rail is provided for mounting the ring gear and includes a rib provided with projections and single stepped portions formed by a certain gap. The construction simplifies the assembly process and prevents the ring gear from deviating outwardly while rotating without any additional fixing means.
