PURPOSE: To realize sure loading/unloading operation by providing a cassette taking out means to push up one end part of a cassette at a side to be protruded from the front face of a cabinet from the bottom surface of a tray by interlocking with operation to move the tray to a slot-out position.

CONSTITUTION: Selective type pop-up mechanisms 56, 57, 62, 66, 70 for taking out the cassette are provided correspondingly to the tray plate 61 of a tray assembly 59. Then, the device is constituted so that a cassette tape 200 loaded to the tray assembly 59 is inclined by pushing up one end part of its discharge side from the tray frame 61 by interlocking with the slot-out operation of the tray assembly 59. Accordingly, after the correct loading of the cassette tape 200 to the tray assembly 59 is realized, the easy taking out operation of the cassette tape 200 from the tray assembly 59 is realized. Thus, the sure loading/ unloading operation can be realized.
