A cassette loading/unloading apparatus for a tape recorder employs a motor driven pinion driving a rack for moving a cassette guided by guide members between a loading/ejection position and an operational position. A single switch senses the insertion of the cassette to begin the loading sequence and also stops the motor when the cassette reaches the operational position. In addition, the switch stops the motor at the conclusion of the ejection sequence when the cassette reaches the ejection position.

DETAILED DESCRIPTION Accordingly, it is an object of this invention to provide a tape recorder having a cassette loading apparatus whic overcomes the above defects.
Another object of this invention is to provide a tape recorder having a cassette loading apparatus in which a cassette holder is quietly and smoothly moved between a cassette insertion position and a cassette operating position.
A further object of this invention is to provide a tape recorder having a cassette loading apparatus which is suitable for front operation.
A still further object of this invention is to provide a tape recorder having a cassette loading apparatus which is easier to operate.
A still further object of this invention is to provide a tape recorder having a cassette loading apparatus operable by an electric motor and in which insertion of the cassette into the cassette holder, cassette loading and return of the cassette to the cassette ejecting position are all detected and/or controlled by a single switch.
According to an aspect of the invention, a cassette loading apparatus for a tape recorder comprises cassette holding means, means for guiding the cassette holding means between a cassette insertion/ejection position and an operative position in a guiding path consisting of a first path portion extending in a first direction and a second path portion extending in a second direction, drive means for moving the cassette holding means between the cassette insertion and operative positions along the guiding path, and electrical means for powering said drive means.
According to a feature of the invention, the cassette loading apparatus is provided for a front-loading video tape recorder with the cassette holding means being effective to accept the cassette inserted from a front of the video tape recorder when in the insertion/ejection position, and the drive means includes a rack extending parallel to the guiding path and a pinion meshing with the rack and being reversibly driven by an electric motor, with one of the rack and pinion being mounted on the cassette holding means, and the other of said rack and pinion being fixedly supported
