Abstract
PURPOSE: To avoid occurrence of the unpleasant sound by securing the operation of the plunger with the first control signal and by the snooze function although the control signal may have the repetition of intermittence and then securing the operation continuously thereafter.
CONSTITUTION: When the control signal supplied from the timer is applied to input terminal T in case power switch S is made and then set under the stand-by state, transistors TR2 and TR3 are turned on. Thus TR5 and TR6 are turned on to give the operation to magnetic driving motor 2 and amplifier/equalizer circuit 3 each. At the same time, TR4 is turned on for the time decided with time constants C and R to actuate plunger 1. Thus the temporary release button is released to carry out the reproducing action. When the control signal pauses for a fixed time by the snooze function and after the reproduction, TR3 is turned off to stop motor 2 and circuit 3 each. Both motor 2 and circuit 3 operate again when the control signal returns to the high level each. Plunger 1, however, maintains the state under which it emerges first owing to the monostable multivibrators of TR1 and TR2 even though the control signal may pause.
