BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transmitter for remotely locking and unlocking a vehicle door lock or the like, and more particularly to a transmitter using an infrared signal.

[0002]

2. Description of the Related Art Conventionally, as an apparatus of this type, Japanese Patent Laid-Open No.
It has been proposed in Japanese Laid-Open Patent Publication No. 2-41878, etc. and is already known. Usually, this type of transmitting device is provided with a monitor light emitting element so that the transmitting state of the infrared signal can be confirmed.

[0003]

By the way, in the above-mentioned conventional transmitter, the infrared light emitting element is usually provided on the front surface of the device in consideration of directivity, while the monitor light emitting element is provided with visibility. In consideration of this, it is provided on the upper surface of the device, for example, the surface provided with the push button. Therefore, it is necessary to separately provide a lens body for each light emitting element, and as a result, there is a problem that the number of parts increases and the cost increases.

[0004]

SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned problems in the prior art, and as a means thereof, a transmitter for transmitting a locking / unlocking signal by infrared rays is provided. A lens body having a laterally wide outer surface formed in a curved surface is provided in front of the transmitting device, and an infrared light emitting body and a monitor light emitting body are arranged side by side inside the lens body. It is a thing.

Embodiments of the present invention will be described below with reference to the drawings. 1 is a plan view of a transmitter according to the present invention, FIG. 2 is a cross-sectional view taken along the line AA of FIG. 1, and FIG. 3 is a bottom view showing the transmitter according to the present invention with a lower case removed.

As shown in FIGS. 1 to 3, a transmitter 1
Is composed of an upper case 2 made of resin and a lower case 3 made of resin which are adhesively fixed to each other. A translucent resin lens (hereinafter, referred to as a lens) 9 is adhesively fixed to the front of the transmitter 1. A printed board 4 is housed in the upper case 2, and circuit elements such as an IC chip 5 and a switch 6 in which a transmission circuit and the like are incorporated are mounted on the upper surface of the printed board 4. Here, a flexible rubber push button 10 is provided on the surface of the upper case 2, and the switch 6 is turned on by the pushing operation force applied to the push button 10. Has been made possible. On the other hand, on the lower surface of the printed circuit board 4, a plus terminal 13 and a minus terminal 14 are provided.
Is provided, and the plus terminal 13 and the minus terminal 1 are provided.
4 is in a state of being in contact with each electrode of the battery 15 housed in the lower case 3. A cover 12 is detachably attached to the lower case 3 with a screw 11 so that the battery 15 can be easily replaced.

On the lower surface of the printed circuit board 4, an infrared light emitting element 7 for transmitting a locking / unlocking signal and a monitor visible light element 8 for confirming the transmission state of this signal.
Are arranged side by side facing the lens 9, and the infrared light emitting element 7 and the monitor visible light element 8 are electrically connected to the transmitting circuit. As a result, the push button 10
If is pressed, the transmission circuit operates via the switch 6,
Since an infrared code signal is transmitted from the infrared light emitting element 7 by the output signal of the transmission circuit, the vehicle side door lock can be locked and unlocked remotely. Where lens 9
Is wide in the lateral direction, and the outer surface is formed in a curved shape in the vertical and horizontal directions. Therefore, the directivity of the infrared light emitting element 7 can be increased vertically and horizontally, and the push button 1
When 0 is pressed and the monitor visible light element 8 is operated, the entire lens 9 shines, and thus the visibility is good. Since the infrared light emitting element 7 and the monitor visible light element 8 are provided close to each other as described above, the infrared light emitting element 7 and the monitor visible light element 8 can be shared by one lens 9, and thus the cost can be reduced.

[0008]

As described above, according to the present invention, in the transmitting device for transmitting the locking / unlocking signal by infrared rays, the lens body having the laterally wide outer surface formed in the curved surface is provided in front of the transmitting device. By providing the infrared light emitting body and the monitor light emitting body side by side inside the lens body,
Unlike the conventional case, it is not necessary to provide a lens body for each light emitting element, and since one lens body can be used in common, there is an excellent effect that the cost can be reduced.
