Amendment 3/4/12 The scope of claims for utility model registration is amended as follows.

[Claim for Utility Model Registration] A small chassis having a small cassette positioning pin provided on the main chassis side of the front of the main body is raised to a predetermined position so as to be mounted on the positioning pin when a small cassette is inserted, and when a standard cassette is inserted. A small cassette mounting mechanism is configured to lower the standard cassette so as not to interfere with the installation of the standard cassette into a predetermined mounting position, and the cassette is selectively inserted into a holder movably supported by a bracket through the cassette insertion opening of the VTR body. In a magnetic recording/reproducing apparatus equipped with a cassette mounting device that moves a standard cassette and a small cassette to respective predetermined mounting positions by moving the holder, the small cassette is placed on the small chassis when the small cassette is inserted. A magnetic recording/reproducing apparatus characterized in that a holder support part is provided which abuts the bottom surface of the holder which has moved to a predetermined mounting position when the chassis is raised and supports the holder at a predetermined mounting position of a small cassette.

Claims (1)

[Scope of utility model registration request] A small chassis having a small cassette positioning pin provided on the main chassis side of the front side of the VTR body is raised to a predetermined position so as to be mounted on the positioning pin when a small cassette is inserted, and moved to a predetermined mounting position for a standard cassette when a standard cassette is inserted. A small cassette mounting mechanism is configured to lower the cassette so as not to interfere with the mounting of the cassette, and a standard cassette and a small cassette are selectively inserted into a holder movably supported by a bracket from the cassette insertion opening of the VTR main body. A magnetic recording/reproducing device comprising a cassette mounting device that moves the holder and mounts each holder in a predetermined mounting position,
A holder support part is provided on the small chassis to abut on the bottom surface of the holder that has moved to a predetermined mounting position when the small chassis is raised when inserting the small cassette, and to support the holder at the predetermined mounting position of the small cassette. A magnetic recording/reproducing device characterized by:
