<p>PURPOSE:To make unnecessary all of a solenoid, a backup capacitor and a driving circuit and to attain the miniaturization, the lightening and the cost down of a device by engaging a member that supplies a power to a magnetic recording and reproducing device with a braking device. CONSTITUTION:A battery 11 is moved along with a guide provided at the magnetic recording and reproducing device in arrow head D direction. At such a time, when a trigger 12 provided at the battery 11 arrives at a position 12'', it is engaged and connected with one end right side of a one-way arm 8. Furthermore, while the trigger advances to a position 12', it makes rotate the one-way arm in a clockwise direction, moving to the left side of the one-way arm 8 and finally returns to a position shown in continuous line, completing the loading of the battery 11. When the battery 11 is moved in arrow head F' direction and a state is no more the loading state of a cassette, the supplying of the power to the magnetic recording and reproducing device is terminated. At such a time, since a sliding plate 3, etc. is impossible to be driven, the sliding plate is situated at a prescribed position.</p> |
