Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a remotely controlled toy equipped with a simple remote control device that controls a drive device to operate only for a predetermined time.

2. Description of the Related Art Conventionally, many remote-controlled toys have been equipped with advanced control functions in a control section that controls the movement of a drive device, so that the user can enjoy complex and sophisticated control of the toy.

However, in order to realize complicated and sophisticated operations, the remote control device becomes complicated and large-sized, and in addition, a certain degree of skill is required in the operation technique. For this reason, it has the disadvantage that it is difficult for younger children and those who are not used to this type of toy to get used to it, and it requires a large space to play with, so it can be used indoors or on a desk. There was a problem that it was not possible to enjoy it easily. Some small toys have tried to solve this problem, but because they use sound sensors for receivers and speakers and microphones for transmitters and receivers, they tend to pick up noise and malfunction, and are expensive. It was on.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a remote control toy suitable for use as a small toy. Specifically, it has a drive device using a motor as a power source, and a transmitter that includes a piezoelectric element and transmits an impulse signal due to discharge, and operates a control circuit of the drive device when the impulse signal is received. Install a receiver,
The control circuit is provided with an electric timer means for stopping the operation of the drive device when a predetermined time has elapsed after receiving the impulse signal, and a storage section is formed in the case of the transmitter by a partition plate having a hole. , it is an object of the present invention to provide a remote control toy in which a desiccant is stored in the storage portion to prevent changes in discharge of the piezoelectric element.

Hereinafter, one embodiment of the present invention will be described based on the drawings. FIG. 1 is a circuit diagram showing an embodiment of the present invention;
FIG. 2 is a perspective view showing details of the transmitter in FIG. 1. In the embodiment of the present invention shown in FIG.
a motor 4 together forming a drive and a capacitor as timer means included in the receiver 2
It is composed of C ₁ .

The transmitter 1 includes an antenna 6 and a piezoelectric transmitter 7 disposed inside the case 5. The piezoelectric transmitter 7 has a piezoelectric element 8 therein, and a push button 9 momentarily applies an impact to the piezoelectric element 8 using the force of springs 10a and 10b to generate electric polarization. Various known piezoelectric elements can be used as the piezoelectric element 8.

The two leads 11a and 11b of the piezoelectric element 8 are
One lead 11a is connected to the antenna 6, and the other lead 11b is arranged very close to the antenna 6. Therefore, when electrical polarization occurs in the piezoelectric element 8 due to the impact of the push button 9, the lead 11b
A discharge occurs from the antenna 6 to the antenna 6.
Impulse signals are emitted from the.

Further, a storage section 5a partitioned off by a partition plate 5b having a plurality of holes 5c is provided at the lower part of the case 5.
is formed, and a desiccant 12 is stored in this storage section 5a. This desiccant 12 is provided in order to keep the humidity in the case 5 low so that the discharge of the piezoelectric element 8 can operate stably without being changed by the humidity.

The receiver 2 receives the impulse signal from the transmitter 1, and is built into the toy main body (not shown). The control circuit built into the receiver 2 is composed of transistors _TR1 to _TR6 , capacitors _C1 to _C5 , resistors _R1 to _R9 , an antenna 13, a mini switch 14, a power supply 15, etc. as shown in the figure. . Each of the transistors TR ₁ to _{TR 6} functions as a so-called gate element, and prevents energization of the motor 4 when the capacitor C ₁ is charged, and prevents energization of the motor 4 when the capacitor C ₁ is discharged. It allows for

First, turn on the mini switch 14 of the control circuit in advance.
, the capacitor C ₁ is brought into a state of storing electricity by the power supply 15 . And each transistor TR ₂ ~
TR ₃ has a high base potential and is in an OFF state, and energization of the motor 4 is blocked.

Here, the push button 8 of the transmitter 1 is made to function as a so-called control rod, and an impulse signal is generated by instantaneous pressure on the piezoelectric element 8, which is sent from the antenna 6 to the receiver 2.
is received by the antenna 13 of. transistor tr ₁
When an impulse signal is input to the base of the capacitor C1, the capacitor _C1 is momentarily discharged, and the current from the capacitor _C1 flows to the transistor _TR1 , which serves as the gate.

Then, the base potential of each of the transistors TR ₂ to TR ₆ becomes low, current flows to the motor 4 via the transistor TR ₆ , and the motor 4 starts rotating. The rotation of the motor 4 is transmitted via the gear 3 to, for example, a wheel 16, which is an operating part of the traveling toy, and rotates the wheel 16. Furthermore, at the same time as the transistors TR ₁ to TR ₆ are energized, current also flows through the capacitor C ₁ and power storage is started again. Then, when the retention time has elapsed and the storage of electricity in the capacitor C ₁ is completed, the base potential of each transistor TR ₁ to _{TR 6} becomes high again and the energization is stopped, so that the motor 4 is also stopped. still,
A rechargeable battery can be used as a power source.

Although the above explanation has been made only with respect to traveling toys, the present invention can of course be applied to any toy that has an operating part, such as a robot toy, a doll toy, or a house toy.

As described above, the remote control toy according to the present invention has a drive device using a motor as a drive source, a transmitter including a piezoelectric element and transmitting an impulse signal by electric discharge, and a transmitter that transmits an impulse signal by electric discharge. The piezoelectric element is configured to include a receiver that operates the control circuit of the drive device, and a timer provided in the control circuit to stop the operation of the drive device when a predetermined period of time has elapsed after receiving the impulse signal. The operation of the toy can be controlled by a combination of simple impulse signal transmission and reception and a timer means, and the remote control device can be small and simple, and it is very easy to operate, so it is popular among children of younger ages. It is something that even those with disabilities can enjoy. Furthermore, since the main body of the toy in which the receiver is mounted can be made smaller, there is a great effect that a small and inexpensive remote-controlled toy can be provided.

Furthermore, in the present invention, since the desiccant is stored inside the case of the transmitter, the humidity inside the case of the transmitter is kept low, and stable operation can be obtained without changing the discharge of the piezoelectric element due to humidity. .
