Is excited to have the same polarity (for example, N pole) repelling the polarity (for example, N pole) of the permanent magnet 16 directly facing this, so that the swinging motion of the pendulum body 12 that swings with a damped inertia swing motion Is promoted by the magnetic repulsion between the drive coil 17 and the permanent magnet 16.
Such a relaxation oscillation circuit (self-running oscillation circuit) 18 is mounted on a wiring board 29 disposed at the bottom of the second support 112 as shown in FIGS.

As shown in FIG. 8, the relaxation oscillation circuit 18 includes an NPN transistor Q1 and a PNP transistor Q2. The base of the NPN transistor Q1 is connected to the collector of the PNP transistor Q2 via a resistor R06, and the base of the PNP transistor Q2 is a period. It is connected to the collector of the NPN transistor Q1 via a setting capacitor C3 and a resistor R02.
One end of the drive coil 17 is connected to the collector of the NPN transistor Q1, and the other end of the drive coil 17 is the positive electrode of the electrolytic capacitor C1 for power supply and the positive electrode of the solar cell 30 (output voltage 2.0V to 2.2V). It is connected to the. Between the collector of the NPN transistor Q1 and the positive electrode of the electrolytic capacitor C1 and the positive electrode of the solar cell 30, a capacitor C2 for setting the time constant of the pulse current flowing through the drive coil 17 to about 0.5 msec. A series circuit with the resistor R01 is connected.
The collector of the PNP transistor Q2 is connected to the positive electrode of the electrolytic capacitor C1 and the positive electrode of the solar cell 30, a bias resistor R03 is connected between the collector and the base of the PNP transistor Q2, and the base of the PNP transistor Q2 is further connected.

The solar cell 30 converts light such as sunlight or illumination light into a current, and the current output from the solar cell 30 is configured to be charged in the power supply electrolytic capacitor C1.
The electrolytic capacitor C1 and the solar cell 30 constitute a power source that supplies power to the relaxation oscillation circuit 18 and the drive coil 17.

Next, the operation of the display rocking device shown in the first embodiment configured as described above will be described.
As shown in FIG. 7, between the permanent magnet 16 and the drive coil 17 of the pendulum body 12 when the pendulum body 12 hangs vertically as shown in FIG. 1 and the drive coil 17 is in a non-excited state. The drive coil 17 is located at a position where the vertical line L1 passing through the center of the drive coil 17 is shifted from the vertical axis L2 of the pendulum body 12 in the swing direction indicated by the arrow A2 by a distance D. In addition, when the solar cell 30 is exposed to light such as sunlight or illumination light, a voltage of 2.0 V to 2.2 V is generated from the solar cell 30. This voltage is supplied to the relaxation oscillation circuit 18 and charged to the electrolytic capacitor C1. The voltage charged in the electrolytic capacitor C1 is used to drive the relaxation oscillation circuit 18 and the drive coil 17.

In this state, when power is supplied to the relaxation oscillation circuit 18 from the solar cell 30 (or the electrolytic capacitor C1), the transistors Q1 and Q2 of the relaxation oscillation circuit 18 follow the time constant set by the capacitor C3 and the resistor R02. For example, the pendulum body 12 is held in the OFF state for a period of 3 to 4 swings back and forth. During this period, no current flows through the drive coil 17 and the drive coil 17 is not excited.
On the other hand, according to the time constant, the terminal voltage of the capacitor C3 shifts from the negative side, which is reverse biased to the base of the transistor Q2, to the positive side, which is forward biased, and the terminal voltage is 0 required to turn on the transistor Q2. When the voltage reaches about 6 V, a base current flows through the transistor Q2, and at the same time the transistor Q2 is turned on, the transistor Q1 is also turned on. At the same time as the current flows through the driving coil 17, the driving coil 17 is excited. The on-time of the transistors Q1 and Q2 at this time is set by the time constant of the capacitor C2 and the resistor R01. Incidentally, the on-time of the transistors Q1 and Q2 when the pendulum body 12 excites the drive coil 17 at a rate of once every 3 to 4 swing reciprocations is 0.5 mmsec. The timing when the drive coil 17 is excited is most preferably when the pendulum body 12 is positioned on the vertical axis L2 that is shifted from the vertical line L1 passing through the center of the drive coil 17 by the distance D.

When a current flows through the drive coil 17 by turning on the transistors Q1 and Q2, the coil end face of the drive coil 17 on the side facing the permanent magnet 16 has the same polarity as the permanent magnet 16 (for example, N pole). Since the excitation is performed so as to be polar, the pendulum body 12 including the first display body 15, the permanent magnet 16, and the weight 20 causes the pendulum support shaft 13 to move due to the magnetic repulsion between the drive coil 17 and the permanent magnet 16. It is swung in the direction of arrow A1 in FIG. The pendulum body 12 including the permanent magnet 16 and the weight 20 is reciprocally swung in the directions of arrows A1 and A2 by the inertial force due to the weight of the pendulum. It swings around a fulcrum.
When the pendulum body 12 is reciprocally swung, the third display body 25 attached to the pendulum support shaft 13 is swung in the left-right direction in conjunction with the first display body 15 as the pendulum support shaft 13 reciprocates. Is done. Further, when the pendulum body 12 is reciprocally swung, the display body support shaft 22 linked via the link mechanism 24 rolls, and therefore the second display body attached to the display body support shaft 22. 21 is swung in the left-right direction in conjunction with the first display body 15.

Oscillates continuously with a period set according to the weight of the pendulum body 12 and the length of the pendulum body 12.

  Note that the number of weights 20 provided at the lower end of the pendulum body 12 is set according to the weight of the second display body 15 attached to the upper end of the pendulum body 12, but the weight of the lower end of the pendulum body 12 is the pendulum body 12. The pendulum body 12 needs to be configured to be held in a vertical state with the pendulum support shaft 13 as a fulcrum.

  As described above, according to the swinging device for the display body shown in the first embodiment, the pendulum support shaft 13 is placed on the first and second support portions 111 and 112 by the pendulum bearing portion 14, and the pendulum support shaft 13 is placed on the pendulum. Since the structure is such that the body 12 is supported so as to be able to roll on the rolling support member 142 of the pendulum bearing 14 as the body 12 swings, the frictional resistance between the pendulum support shaft 13 and the rolling support member 142 is As a result, the capacity of the solar cell 30, the relaxation oscillation circuit 18 and the drive coil 17 can be reduced, and the pendulum bearing portion 14 has a thin metal rod-like elastic support piece 142a. Since it comprises the dynamic support member 142, a bearing mechanism for the pendulum body 12 that has no frictional resistance and can absorb the impact force applied to the pendulum support shaft 13 can be provided simply and at low cost.
