Description

[Detailed description of the invention] The present invention relates to a remote control toy that is remotely controlled by infrared rays, and in particular, depending on the presence or absence of a control signal, the traveling motor is driven in forward or reverse rotation, and if necessary, a manual The present invention relates to a traveling toy in which driving of a traveling motor is stopped by operating an operation switch.

The present invention will be described with reference to an embodiment shown in the figure below. Reference numeral 1 denotes a transmitter, and the transmitter 1 side is equipped with a light emitting element 2 such as an infrared light emitting diode. A control circuit 3 including an oscillation circuit for controlling the switch is provided, and the control circuit 3 is controlled by, for example, a push button switch 4, and when the push button switch 4 is pressed, a control signal is sent from the light emitting element 2, and the control circuit 3 is controlled by a push button switch 4. It is configured to stop sending signals when released.

Reference numeral 5 denotes a controlled circuit mounted on a traveling toy or the like, and this circuit 5 is connected to a receiver 6 equipped with a light receiving element for receiving an infrared signal from the transmitter 1 and converting it into an electric signal. A drive circuit 7 is provided for amplifying the output signal to an appropriate signal level and operating a motor control circuit 8 using a semiconductor switch circuit.

The drive circuit 7 and motor control circuit 8 are configured as shown in FIG. 1, for example. That is, transistors Q3 and Q4 are connected to a drive circuit 7 consisting of transistors Q1 and Q2, respectively, and a battery E2 is connected so that current flows to the motor M in the positive direction.
and transistor Q4, and battery E1 and transistor Q3 are connected so that the current flows in the opposite direction. Therefore, transistors Q2 and Q4 and battery E2 function as a forward rotation drive circuit for motor M, and transistors Q1 and Q3 and battery E1 function as a reverse rotation drive circuit.

Further, a manually operated switch S1 is provided on the base side of a transistor Q3 constituting a reverse drive circuit that causes current to flow in the opposite direction to the motor M, or a switch S2 is provided between the base of the transistor Q3 and ground.

With the above configuration, when the push button switch 4 on the transmitter 1 side is turned on, a square wave pulse voltage is applied to the light emitting element 2 through the control circuit 3 during that period, and the light emitting element 2 outputs a transmission signal of a predetermined level. be done. When there is no output signal, it is set as 0, and when there is an output signal, it is set as 1. On the other hand, in the controlled circuit 5, when the signal from the transmitting side is 0, the collector and emitter of the transistor Q1 of the drive circuit 7 are in a non-conducting state.If this is 0, the transistor Q2 is 1, and the switch S1 is When the switch S1 is closed, conduction is established between the collector and emitter of the transistor Q3 of the control circuit 8 via the switch S1, which is set to 1. Similarly, the transistor Q4 is 0, so that the motor M is set to the same transistor Q3.
The reverse operation is performed by the battery E1. Next, when the signal from the transmitting side is 1, the transistor Q1 of the drive circuit 7 is 1, and the transistor Q2 is also 1.
becomes 0, the transistor Q3 of the control circuit 8 becomes 0, and the transistor Q4 becomes 1. When the push button switch 4 on the transmitting side is pressed to output an output signal, the controlled circuit 5 causes the motor M to rotate in the normal direction by the battery E2 through the transistor Q4.

Next, when the switch S1 is opened to open the reverse rotation drive circuit, the transistor Q3 becomes 0 and the motor M remains stopped, and only when there is a signal from the transmitting side, the transistor Q4 becomes 1 and the motor M is driven in the forward direction.

FIG. 2 shows another embodiment, which forms a drive circuit 7' for amplifying the output signal from the receiver 6 to operate the relay RY, and a motor control circuit 8 provided with the contacts of the relay RY. The motor M is configured to be controlled in forward and reverse directions through the motor M.

The contacts of the relay RY of the motor control circuit 8' are, for example, a normally open contact a and a normally closed contact b, as shown in FIG.
These normally open contacts a,
Connect the positive side of the power supply battery E2 and the negative side of the battery E1 to the normally closed contact b side, and connect the common contact c
One end of the motor M is connected to the side. In addition, the motor M and the other end, the positive side of the battery E1, and the battery E
On the other hand, a switch S1 that can be turned on and off manually is inserted between the connection line connecting the negative side of the battery E1 and the normally closed contact b of the relay RY.

With the above configuration, when the push button switch 4 on the transmitter 1 side is turned on, a rectangular wave pulse voltage is applied to the light emitting element 2 through the control circuit 3 during that period, and the light emitting element 2 outputs a signal at a predetermined level. . On the other hand, when the controlled circuit 5, for example, the manual operation switch S1 of a traveling toy, is closed, a negative voltage is normally applied from the motor M battery E1 through the normally closed contact b side, and at this applied voltage, for example, the If it is set to reverse the
The traveling toy can be made to travel in the opposite direction when there is no signal from the transmitter 1 side. Next, the above transmitter 1
When a light emitting signal is emitted from the side, the relay RY is activated through the receiver 6 and the drive circuit 7', and the above contact switches from the normally closed contact B side to the normally open contact A side, and the motor M is switched from the battery E2 side to the positive side. The running toy can be moved forward during the period when the signal from the transmitter 1 side is being applied. Next, the controlled circuit 5, that is, the operation switch S1 of the traveling toy
If it is open, the power supply from the battery E1 side is cut off, and the traveling toy remains in a stopped state when there is no signal from the transmitter 1 side. Next, when a light emission signal is issued from the transmitter 1 side, the relay RY is activated in the same way as above, and the motor M is connected to the battery E2.
A positive voltage is applied to the toy to move it forward.

Therefore, the battery E2 acts as a forward rotation drive circuit for the motor M through the normally open contact a of the relay RY in FIG. 2, and the battery E1 and switch S1 act as a reverse rotation drive circuit through the normally closed contact b of the relay RY. It has the following functions.

As explained above, according to the present invention, the motor M
Since a forward rotation driving circuit for rotating in the forward direction and a reverse rotation driving circuit for rotating in the opposite direction are provided, the semiconductor switch circuit in the controlled circuit 5 is controlled by the presence or absence of a transmission signal from the transmitter 1 side. Alternatively, switching control is performed on the relay RY contact point, and in connection with these controls, the motor M is rotated in the forward and reverse directions, so that, for example, the traveling toy can be switched between forward and backward operation.

Furthermore, since a manually operated switch S1 for opening and closing this circuit is provided in the above-mentioned reverse drive circuit, by opening this switch S1 as necessary,
For example, a running toy that is moving backwards can be stopped.

Therefore, the traveling toy according to the present invention has one on the transmitter side.
With an extremely simple configuration that only requires one operation button and one manual operation switch on the receiver side, it is possible to make the traveling toy take on multiple running modes such as forward, backward, and stop.
