ことが可能となるものである。Means for Solving the Problems In order to achieve the above object, the cassette loading device of the present invention provides a cassette having an insertion hole through which a brake release pin for releasing engagement between at least a reel for winding a recording medium and a brake is inserted. A cassette mounting device for mounting a cassette, the brake being inserted into a height regulating portion having a diameter larger than the insertion hole that abuts one end surface of the cassette, and the passer formed coaxially with the height regulating portion. a first pin having a release pin portion; and an end surface that abuts one end surface of the cassette;
and second and third pins set at the same height as the height regulating part of the pin, and the first to third pins are arranged on the same plane on which the cassette is placed. With the above configuration, the height position of the cassette is regulated by the height regulating portion of the first pin and the end surface regulating the height of the second and third pins. Since the height position of the end face of the cassette is set by the three pins of the mud, there is no rattling or damage to the exterior due to the presence of the fourth pin, and the number of pins regulating the height is also reduced. This makes it easier to perform the positioning work, improving work efficiency, and further improving the accuracy.
