<p>PURPOSE:To discharge a cassette although the power supply is cut off in the cassette loading mode, by forming stepped parts to a cassette shifting member so that the hook between the cassette shifting member and a cam part can be released. CONSTITUTION:A cassette 5 is loaded into a cassette holder 3 toward an arrow mark, and a cassette shifting plate 6 moves. Thus the driving force is applied to a cam rotor 13 from a motor, and the rotor 13 is turned. The cassette 5 is loaded in the first half of a turn of the rotor 13 to the second position where the reproduction, etc. is possible. In the discharging mode of the cassette 5, the rotor 13 has the latter half of a turn to be reset to its original position. Then the cassette 5 is sent back to the first position where the cassette can be set and unset from the second position. A stage part 12h shown by oblique lines is formed to a cassette shifting arm 12 so as to not to touch the arm 12 to a pin 13a of the rotor 13 in the direction of height. In such constitution, the cassette can be sent back to the first position and then dicharged with a push of a discharge arm for emergency use in case the driving force of the motor is not available.</p> |
