Abstract
PURPOSE:To enable ejection even when a main switch is turned off, by connecting a switch, operated at the time of loading and unloading of a cassette, directly to a battery and by interposing a timer switch circuit between the switch and a motor. CONSTITUTION:When a cassette is loaded while an engine key S2 is in the ON state, a switch S1 is turned on and the transistors (TR) Q1 and Q2 of a timer switch circuit 2 turn on to supply electric power to a motor 3. At ths time, TRs Q3 and Q4 are in the off state and a plunger 4 is not driven. When the cassette is loaded while the engine key S2 in the OFF state, on the other hand, the switch S1 is turned on to charge a capacitor C2 through a capacitor C1, so the motor 3 is conducted; and a TRQ5 is in the off state while TRs Q3 and Q4 are turned on, so a plus pulse appears at the collector of the TRQ3 to turn on both TRs Q6 and Q7, then plunger 4 is conducted. Consequently, a trigger mechanism is actuated to drive an ejection mechanism by utilizing the revolution force of the mtor 3.
