0e or receiver 77 switch 91a, 91
Transmitter 8 by operating b, 91c, 91d, and 91e.
When the channel on the 8 side and the channel on the receiver 77 side are matched and the control switch 89 of the wireless transmitter 88 is pressed in this state, the wireless transmitter 88
The on _/ off signal sent from
a ₀ turns on. As a result, relay R ₁ is energized, contact a ₁ is turned on, relay R ₃ is energized, and
Timer TR ₀ is activated. When the a contact a ₃₁ is turned on, the relay R ₃ is self-held, and when the a contact a ₃₂ is turned on, the motor 32 is driven.

At this time, if the intermittent rotation contact S ₄ is turned on, the timer TR ₁ is activated at the same time as the motor 32 is activated. When timer TR ₁ times up, contact Ta ₁ is turned on, timer TR ₂ is activated, and relay R ₄ is activated to self-hold by turning on contact A ₄ and turning off the motor by turning contact B ₄ . 32 stops. Next, when the timer _TR2 times up, the contact _Tb2 is turned off and the relay _R4 is demagnetized, and when the b contact _b4 is turned on, the motor 32 is driven and the timer _TR1 is activated. Repeat the same operation below. The motor 32 is intermittently driven each time the timers TR ₁ and TR ₂ are up, and the top plate 6 is intermittently rotated by a constant angle in response to the adjustment time of the timers TR ₁ and TR ₂ .

If the touch switch contact _S5 is turned on, the timer _TR1 will not operate, the motor 32 will continue to drive, and the top plate 6 will continue to rotate. However, when a human body such as a hand comes into contact with the conductor 82, the touch switch TS is grounded through the conductor 82 and the human body, so the switch (TS) is turned on and the relay _R5 is turned on.
is activated, relay R ₄ is energized by turning on contact A ₅ , contact A ₄ is turned on and relay R ₄ is self-holding, timer TR ₂ is activated, and at the same time, contact B is turned on.
_b4 is turned off, the motor 32 stops, and the top plate 6 stops rotating. Next, due to the time-up of timer TR ₂ , contact Tb ₂ is turned off, relay R ₄ is demagnetized, and a
Contact _A4 turns off and B contact _B4 turns on, returning to the circuit state before the touch switch TS was turned on.
The motor 32 is driven and the top plate 6 is rotated.

As long as the activated timer TR ₀ has not timed up, even if the control switch 89 of the radio transmitter 88 is pressed again, the single relay R ₀
operates, and the other circuit conditions do not change at all. When the timer TR ₀ times up, the contact Ta ₀ turns on and the contact Tb ₀ turns off, so the relay R ₅ is energized, and the a contact a ₆₂ turns on, causing the relay R ₆ to self-hold, and the a contact a ₆₁ is turned on, and the b contact _b6 is turned off. When control switch 89 is pressed in this state, relay _R0
Relay R ₂ is energized by turning on contact a ₀ of , and b
Since relay R ₃ is demagnetized by turning off contact b ₂ ,
A contact a ₃₂ is turned off and the motor 32 stops. At the same time, when the b contact _b2 is turned off, the timer _TR0 is reset, the contact _Ta0 is turned off, and the contact _Tb0 is turned on, so that the timer _TR3 is activated. In this state, even if the control switch 89 of the transmitter 88 is pressed, the relays R ₀ and R ₂ are only energized during that time, and the circuit state does not change. When timer TR ₃ times up, relay R ₆ is demagnetized by turning off contact Tb ₃ , turning on contact B ₆ and turning on contacts a ₆₁ and a ₆₂ .
is turned off and the circuit returns to its initial state.

When the snap switch 92 is set to the upper position and the manual contact S ₃ is turned on, if the intermittent rotation contact S ₄ is turned on as in the case of the radio described above, each time the timers TR ₁ and TR ₂ time up. motor 32
is driven intermittently, and the top plate 6 is intermittently rotated by a constant angle in accordance with the adjustment time of the timers TR ₁ and TR ₂ . Furthermore, if the touch switch contact S ₅ is turned on, the top plate 6 continues to rotate, and the top plate 6 continues to rotate until the adjustment time of the timer TR ₂ elapses after the human body comes into contact with the conductor 82. stops.

As shown in FIG. 4, the base of the decorative body 17 is
The movable body 18 is moved toward the holding tube 8 side so that the colored transparent plate 19 and the light bulb 22 are inserted into the lower part of the holding tube 8. In this state, the light bulb 22 is turned on, and the motor 21 is turned on. When the colored transparent plate 19 is rotated around the vertical axis 20, the light from the light bulb 22 is incident on the optical fibers of the decorative body 17 through the colored transparent plate 19, and as a result, the decorative body 17 is rotated as the colored transparent plate 19 rotates. Shining brightly as the colors change,
It can give a very beautiful and luxurious impression. Furthermore, the decorative body 17 can be removed from the holding cylinder 8 and a chandelier, fresh flowers, or other decorative body can be fitted and held in the holding cylinder 8. In this case, the movable body 18 can be moved as shown by chain lines in FIGS. 3 and 4.
