PURPOSE:To draw a tape out securely, by providing an interlocking means which allows the 1st and the 2nd holders to move in associated relation with regard to a drawing-out means. CONSTITUTION:Drawing-out pins 44 and 48 as tape drawing-out members and a motor 56 for driving a drawing-out mechanism are provided in an adapter device, and consequently the need for a mechanism for transmitting power for the movement of the drawing-out members from a small-sized VTR side is eliminated, thereby simplifying the structure of the portable VTR having essential conditions of portability. A large-sized cassette insertion switch 58 is closed by lowering a plate 59 by the bottom surface of a large-sized cassette when the large-sized cassette is set in a holder 26 is pressed. A lowering completion switch 60 for the A holder 26, on the other hand, is closed by being pressed by a pin 61 which moves as the holder 26 is lowered. The lock lever 62 of the A holder 26 is energized in such a direction that it is locked by a spring 63, and is unlocked only when a solenoid is drawn, thereby ejecting the holder 26. |
