[Operation and Action of First Embodiment]
When it is detected that the customer has approached the slide doors 3A and 3B, the electric motor is driven to open the slide doors 3A and 3B. With the opening of the slide door 3A, the rotating bodies 41 and 53 rotate. When the rotators 41 and 53 rotate, the rotors of the generators 39 and 51 rotate. Since both the generators 39 and 51 have the same configuration, the power generation operation will be described using the generator 39 as an example.

  When the rotor 101 of the generator 39 rotates, a large number of claw poles 109A and 119A are magnetized to face one of the N and S poles of the rotor 101, and the large number of claw poles 111A and 117A rotate. It is magnetized opposite to the other magnetic pole of the N pole and S pole of the child 101. An alternating counter electromotive force is generated in each of the first and second power generation coils L1 and L2 by the magnetic field generated from the magnetized claw pole. The AC counter electromotive force generated in the first power generation coil L1 has the same phase as the counter electromotive force generated in the second power generation coil L2.

  In the positive cycle of the AC counter electromotive force generated in both the power generation coils L1, L2, the potential V1 of the first coil terminals T11, T21 of each power generation coil is higher than the potential V2 of the second coil terminals T12, T22. Further, the potential V3 of the third coil terminals T13 and T23 of each power generation coil is higher than the potential V2 of the second coil terminals T12 and T22 by [(V1−V2) / 2]. On the contrary, in the negative cycle of the AC counter electromotive force, the potential V2 of the second coil terminals T12 and T22 of each power generation coil is higher than the potential V1 of the first coil terminals T11 and T21. Further, the potential V3 of the third coil terminals T13 and T23 of each power generation coil is higher than the potential V1 of the first coil terminals T11 and T21 by [(V2−V1) / 2].

Capacitor C3 is charged through diode RD3 by back electromotive force generated in first coil portion PL21 and second coil portion PL22 of second power generation coil L2 in the forward cycle.

  Capacitor C2 is charged through diode RD2 by back electromotive force generated in the opposite polarity to the positive cycle in first coil portion PL11 and second coil portion PL12 of first power generation coil L1 in the negative cycle. In addition, the capacitor C4 is charged via the diode RD4 in the negative cycle by the back electromotive force generated in the first coil part PL21 and the second coil part PL22 of the second power generation coil L2 with the opposite polarity to the positive cycle. The

  The series circuit of the capacitors C1 to C4 is charged to a voltage higher than the voltage of the absolute value of (V1-V2) in all cycles of the AC counter electromotive force generated in both the power generation coils L1, L2. This high charging voltage is supplied from the output connector 81 to the input connector 211 via the connection line.

  The high charging voltage is supplied to the ten light emitting diodes D1 to D10 of the light source substrate 203 via the resistor RT. Since the high charging voltage is sufficiently higher than the total value of the forward drop voltages of the ten light emitting diodes D1 to D10, all the light emitting diodes on the light source substrate 203 are turned on. Similarly, the high charging voltages charged in the four capacitors by the AC counter electromotive force generated in both the power generation coils of the generator 51 are also supplied to the ten light emitting diodes of the light source substrate 205, and the light emitting diodes of the light source substrate 205 All lights up.

As the slide door 3A is closed, the rotating bodies 41 and 53 rotate. When the rotators 41 and 53 rotate, the rotors of the generators 39 and 51 rotate. Similar to the time when the sliding door 3A is opened, the four capacitors are charged by the back electromotive force of the alternating current generated in the power generation coils of the generators 39 and 51. The capacitance of the capacitor is set to a large enough capacity to light up the light emitting diodes of both light source boards 203 and 205 for a long time. As a result, even while the sliding doors 3A and 3B are not opened and closed, the light emitting diodes of both the light source boards 203 and 205 are turned on, and the display panel 201 can display the store name “BEP”.

Supply to the diode. As a result, the amount of current supplied to each light emitting diode does not vary greatly due to variations in the characteristics of each light emitting diode, compared to a configuration in which charging voltage is supplied to many light emitting diodes connected in parallel. By supplying the same amount of current to the diodes, each light emitting diode can be lit with substantially the same amount of light emission. As a result, the display panel 201 of the image display unit 9 can clearly display an image such as a store name.

Be forced. As a result, the rotation of the rotating body can be reliably transmitted to the rotating shaft of the generator as compared with the configuration in which the rotating body is supported by a member separate from the generator. Moreover, since the gear transmission mechanism of each power generation unit is set with the number of teeth of the gears 43 and 47 and the gears 55 and 59 so that the rotation of the rotating body is accelerated and transmitted to the rotation shaft, The amount of power generation can be increased.
