Description

[Detailed Description of the Invention] [Object of the Invention] <Industrial field of application> The present invention relates to an operation switch and a transmission means for transmitting a remote operation signal to an external receiver a plurality of times each time the operation switch is pressed. Relates to a transmitter of a remote control device received in a portable casing, in particular to a transmitter suitable for use in a remote control device for a vehicle door lock device.

<Prior Art> Conventionally, for example, there is a remote control device that remotely controls lock / unlock of a door of an automobile from a remote position outside. In such a device, an operation signal is transmitted from a portable transmitter to a receiver on the side of the device (door lock device) to be operated to operate the device (for example, the actual device). (See Kaihei 2-89160). At this time, in order to inform the operator that the signal was transmitted, the transmitter was provided at the same time as the signal was transmitted, or before or after the signal was transmitted.
There is one that blinks an LED or the like (for example, actual exploitation Sho 63-86264
(See the official gazette).

However, in this type of remote control device, in order to ensure that the signal from the transmitter is received by the receiver, the signal is output multiple times every time the operation switch on the transmitter side is operated once. The power consumption tends to increase because the notification means such as the LED is activated each time, and the transmitter is portable, and the power supply capacity is small, so the transmitter can be used. There was a problem that time tended to be shortened.

<Problems to be Solved by the Invention> In view of the above problems of the conventional technology, the main object of the present invention is to reduce the power consumption and extend the usable time of a transmitter of a remote control device. To provide.

[Object of the Invention] <Means for Solving the Problems> According to the present invention, such an object is directed to a receiver that can be carried by a battery as a power source and is separated from the battery each time the operation switch is pressed. A transmitter of a remote control device for transmitting a remote control signal a plurality of times over a predetermined time, wherein the signal is transmitted once when the operation switch is pressed, and is shorter than the predetermined time only once. The present invention is achieved by providing a transmitter of a remote control device, which is provided with an informing means for informing the outside over time.

<Operation> In this way, the operating time of the notification means for transmission confirmation is reduced, and the ease of operation confirmation by the operator is not impaired.

<Embodiment> Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 schematically shows the construction of a vehicle keyless door lock device to which the present invention is applied. The transmission part 4 and the rechargeable battery 5 are built in the grip part 3 of the keyed transmitter 2 having the mechanical key part 2a for the vehicle 1. A pair of light emitting elements 7 and 8 formed of an infrared LED element covered with an infrared transmissive cover 6 are provided on the end surface of the grip portion 3 from which the mechanical key portion 2a projects. A push button type operation switch 9 connected to the transmission circuit 4 is provided on one surface of the grip portion 3. Further, at a position adjacent to the operation switch 9 on the surface of the grip portion 3, a light emitting element 10 composed of a visible light LED element for informing the operator that a signal has been transmitted is provided as described later. Has been.

On the other hand, a control device 12 which also functions as a receiver is provided at an appropriate position on the vehicle 1 side. The control device 12 includes a pair of light receiving elements including photodiode elements attached to the left and right doors.
It is connected to 13 and 14. Further, the control device 12 is connected to actuators 17 and 18 that drive the left and right door lock devices 15 and 16.

FIG. 2 is a schematic circuit diagram of the transmission circuit 4. The CPU 20 that actually generates a predetermined signal is supplied with power from the battery 5 via the pin P12. Further, the battery 5 is also connected to the pin P13 of the CPU 20 via the operation switch 9, and every time the operation switch 9 is turned on, a reset signal is sent to the CPU 2
It is supposed to be input to 0. CPU20 pins P1-P6,
P14 to P21 are respectively connected in parallel to the pin P7, and by cutting some of these connecting lines, a desired code can be generated.

The pin P23 of the CPU 20 is connected to the base of the transistor T1. The transistor T1 has an emitter connected to the battery 5 and a collector connected to the light emitting elements 7 and 8.
Then, the transistor T1 is turned on according to the output from the pin P23, power is supplied from the battery 5 to the light emitting elements 7 and 8, and light is emitted.

The pin P22 of the CPU 20 is connected to one end of the light emitting element 10.
The other end of the light emitting element 10 is connected to the battery 5 and the pin P2
Power is supplied to the light emitting element 10 in accordance with the output from 2 to emit light.

The operation procedure of this embodiment will be described below with reference to the time chart of FIG.

First, when the operator turns on the operation switch 9 of the key transmitter 2, the reset signal is input to the pin P13 of the CPU 20 and the time
After t1 has elapsed, the pulse signal corresponding to the above code at the first time t2 based on the connection state of pins P1 to P6 and P14 to P21
It is output from P23 and the battery 5 passes through the transistor T1.
The light-emitting elements 7 and 8 are supplied with electric power to emit light. Then, after a lapse of time t3 after the end of the first pulse signal output, the second pulse signal similar to the first pulse signal is output from the pin P23, and the output of the second pulse signal is completed. Then, after the lapse of time t3, the third pulse signal
It is output from P23, and the light emitting elements 7 and 8 emit light according to the signal. Here, at the same time that the third pulse signal is output, the signal is output from the pin P22 only once and for the time t2, and the light emitting element 10 actually emits light for the time t2.

Needless to say, the present invention is not limited to the above-described embodiment and can be applied in various ways. For example, in the present embodiment, the signal was transmitted using infrared rays as a medium, but radio wave ultrasonic waves or the like may be used as a medium. Further, sound may be generated as a notification means for a predetermined time. Furthermore, in this embodiment, at the same time when the third pulse signal is output (transmitted), the light emitting element is emitted for the time t2.
Although 10 is made to emit light, it may be made to emit light at the same time when the operation switch 8 is pressed, or may be made to emit at the same time as the first pulse signal is output.

[Effects of the Invention] As described above, according to the present invention, each time the operation switch is pressed, the fact that a signal is transmitted is notified once and for a time shorter than the signal transmission time to the outside. The operation time of the notification means for transmission confirmation can be suppressed, the power consumption can be reduced, and the ease of operation confirmation by the operator is not impaired. From the above, the effect of the present invention is extremely large.
