PURPOSE: To obtain a device whose number of components is small, which can be constituted simply and whose cost is low.
CONSTITUTION: A cassette holder 1 for a cassette mounting device in a front loading-type VTR is moved from a horizontal position to a vertical position via a driving arm 23a. A guide pin 26 for the driving arm is fitted, so as to be freely slid and moved, into a cam groove 25 in a slide member 24 which can be moved horizontally, the slide member is driven by a driving motor, and the cassette holder is moved. The slide member 24 is provided with a spring 30, and the cassette holder 1 is moved horizontally against the spring when a cassette is inserted. Consequently, since the spring acts only when the cassette is inserted, the force of the spring can be reduced, and an operation is made easy when the cassette is inserted. In addition, since the movement speed of the cassette holder can be set properly by the shape of the cam groove, the movement speed of the cassette holder can be made slow so as to lessen a shock when the cassette holder is shifted from a horizontal movement to a vertical movement.
