For example, it is electrically connected to the secondary spiral coil 3 disposed on the peripheral wall of the paper cassette 1 on the copying machine insertion side. Also, on the copying machine main body side, a primary spiral coil 4 (not shown) is installed at a position facing the secondary spiral coil 3 when the paper cassette 1 is loaded into the copying machine main body 16. It is provided. Therefore, when the paper cassette 1 is loaded into the copying machine main body, the

される。 Here, the operating principle of this embodiment will be explained with reference to FIG. One end of the primary spiral coil 4 is connected to a power source 7 of the main body of the copying machine, and the other end is connected to the collector of a transistor 5. The oscillation output of the oscillation circuit 6 is supplied to the base of the transistor 5, and drives the transistor 5 in a pulse manner. Therefore, the current Q 1 flowing through the primary spiral coil 4 is controlled by the transistor 5 and becomes a pulse (the third
Diagram a). Therefore, an induced electromotive force V 2 is generated in the primary spiral coil 4 and the secondary spiral coil 3 disposed opposite to each other due to mutual induction (FIG. 3b). The induced electromotive force V 2 generated in the secondary spiral coil 3 is rectified by diodes 8 and 9 and smoothed by a capacitor 10. Furthermore, since the induced electromotive force V 2 changes depending on the proximity between the primary spiral coil 4 and the secondary spiral coil 3, the voltage stabilizing circuit 12 adjusts it to the desired voltage Vcc (the third Figure c). The stable voltage Vcc is then smoothed by a capacitor 11 and then supplied to the electronic circuit 2.

In place of the primary spiral coil 4 described above, the copying machine main body 16 is provided with a primary solenoid 15 in which an insulated winding is wound around a cylindrical magnetic body 13 having a cylindrical cavity. Further, the insertion end of the paper cassette 1 is provided with a secondary solenoid 25, which is a cylindrical magnetic body 14 and an insulated winding, instead of the secondary spiral coil 3 described above. When the paper cassette 1 is loaded into the main body of the copying machine, the secondary solenoid 25 is inserted into the cylindrical cavity of the primary solenoid 15 without contacting it. Here, a pulse current is passed through the primary solenoid 15 to generate an induced electromotive force in the secondary solenoid 25 due to mutual induction, thereby supplying power to the electronic circuit 2. By using a solenoid instead of a spiral coil in this way, a stronger induced electromotive force can be generated.

The copying machine main body 16 is equipped with a primary solenoid 19 having an insulated winding wound around a cylindrical magnetic body 17 having a circular cavity. Furthermore, a cylindrical magnetic body 18 is placed at the insertion end of the paper cassette 1.
A secondary solenoid 26 having an insulated winding wound around the base thereof is provided. In this case, the secondary solenoid 2 inserted into the cavity of the primary solenoid 19
Since no insulated winding is wound around the tip of the primary solenoid 19, the primary solenoid 19 can be easily inserted into the cavity and positioned.
