<p>PURPOSE:To simplify an eject operation and prevent a wasteful power consumption by providing a feeder system path for the eject independent of the feeder system path to an electric circuit including a recording and reproducing circuit. CONSTITUTION:A CPU 11 is disposed in a power source device and a power source battery 10 is connected between its power source impressing terminal VDD and an earth. By connecting the power source battery 10, a rest pulse is outputted from a power ON reset circuit 12 and the rest is applied to the CPU 11. To the power source battery 10, the first feeder switch 14 inserted into the first feeder system path for feeding to a whole electric circuit including a recording and reproducing circuit and excluding an eject mechanism and the second feeder switch 16 inserted into the second feeder system path for feeding to an electric circuit 15 for the eject mechanism is connected. The first and the second feeder switches 14, 16 are respectively independently ON and OFF controlled according to levels of outputs terminals O1, O2 of the CPU 11.</p> |
