Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a light reception control device that controls transmission of light emitted from a transmitter.

2. Description of the Related Art In recent years, many electronic devices have been commercially available as receivers that are remotely controlled using infrared remote controllers as transmitters. For example, many audio devices such as video devices are remotely controlled using such infrared remote controllers. Remote control in such conventional devices is performed as follows. In other words, the light emitted from the infrared remote control is directly transmitted to the light-receiving window of the operating electronic device and received by the light-receiving element inside, and the received signal is transmitted to the light-receiving window of the operating electronic device and received by the microcontroller inside the device. Electronic devices were operated by being processed.

Problems to be Solved by the Invention In conventional electronic equipment that is operated remotely, it is difficult to control multiple devices of different models (different types of codes) at the same time.
However, it is possible to select and operate multiple devices of the same model (same code) installed in close proximity using only one infrared remote controller (for example, select and operate multiple devices of the same model (same code) with only one infrared remote controller). Even if you try to operate multiple video cameras at the same time, it will malfunction because the codes selected are the same, and as a result, it will not work properly.

Therefore, in the conventional device, when a plurality of devices of the same model having the same code were to be remotely controlled at the same time, it was necessary to use wired remote controllers for the number of devices. For this reason, the remote control becomes troublesome for the user, and the cost increases for the number of units, which is extremely uneconomical.

Means for Solving the Problems In order to solve these problems, the present invention provides a front window into which the light emitted by the selection means of the transmitter enters,
A light-receiving element is provided to receive the light that has passed through the front window, and a determining means is connected to the light-receiving element to determine whether or not the light has been received. A light transmission means is provided to control transmission to the rear,
A rear window was provided for transmitting the light transmitted rearward by the light transmission means to the light receiving window of the receiver.

Effect: Therefore, the light emitted from the selection means of the transmitter is received by the light receiving element through the front window, and the signal is sent to the determination means and internally processed to determine whether the target device has been selected or not. is determined, and if the target device is selected, the light is transmitted from the rear window using the light transmission means.

It can be sent to the light receiving window of the receiver to operate it.

In this way, by sending the light emitted from the transmitter to the light receiving window of the receiver via the light receiving control device,
Using one transmitter, it is possible to simultaneously operate a plurality of receivers of the same model with the same code, making remote control extremely easy. In addition, by simply attaching such a light receiving control device to the light receiving window of an existing receiver, it is possible to easily control such an existing receiver, which allows for a wide range of use and is economical. becomes. Furthermore, the light receiving window of conventional receivers is fixedly provided on the front of the main body, which limits the direction in which light can be received, but by using such a light receiving control device, the degree of freedom in the direction in which light is received can be increased. It becomes possible to take a wider range.

Embodiment A first embodiment of the present invention will be explained based on FIGS. 1 and 2. A front window 2 is provided on one side of the light reception control device 1, and a rear window 3 is provided on the opposite side. A light-receiving element 4 is located inside the front window 2.
is installed.

A microcomputer 5 is connected to the light receiving element 4 as a determining means. This microcomputer 5
is connected to an electronic shutter 6 as a light transmitting means, and this electronic shutter 6 is located inside the rear window 3.

Further, the infrared remote control 7 as a transmitter is provided with a plurality of selection buttons 9 as selection means in order to simultaneously operate a plurality of electronic devices 8 as receivers of the same model having the same code. . On the other hand, a light-receiving window 10 is formed on the front surface of the main body of the electronic device (video, stereo, etc.) 8, and the light-receiving control device 1 is mounted in front of the light-receiving window 10.

In such a configuration; now, the light reception control device 1
It is assumed that a plurality of electronic devices 8 are installed in close proximity to each other. Assuming that the second electronic device 8 is now selected by the selection button 9 of the infrared remote controller 7, the light emitted from the infrared remote controller 7 will be transmitted to multiple electronic devices 8 having the same code. The light enters all light reception control devices 1. However, at this time, only the light reception control device @1 attached to the light reception window 10 of the second electronic device 8 is controlled to operate.

That is, the light emitted from the infrared remote control 7 is received by the light receiving element 4 through the front window 2, and the signal is sent to the microcomputer 5. Then, the microcomputer 5 processes the signal internally, and when it is confirmed that the second electronic device 8 has been selected, the microcomputer 5 sends a signal to the electronic shutter 6 to open the door. When the electronic shutter 6 is opened, the light incident from the front window 2 passes through the rear window 3 as it is and is sent out to the outside of the light reception control device 1.

Thereafter, the emitted light enters the light receiving window 10 of the second electronic device 8 and is further received by an internal light receiving element (not shown), thereby operating the second electronic device 8. I can do it. Note that other devices are not operating due to this selection button 9.

As mentioned above, multiple electronic devices 8 with the same code
Even if the devices are placed close to each other, the microcomputer 5 inside the light receiving control device 1 can determine which device has been selected, and the electronic shutter 6 can be opened and closed based on this. Even if a plurality of electronic devices 8 having the same code are arranged in close proximity, other devices will not malfunction.

A mirror 11 serving as a light transmitting means is located between the front window 2 and the rear window 3 of the light reception control device 1 and is rotatably attached. This mirror 11 replaces the electronic shutter 6 in the first embodiment and is connected to the microcomputer 5. Note that the other configurations are slightly different from the first embodiment except for the arrangement and the connection state is the same, so a description thereof will be omitted here.

In such a configuration, light entering from the front window 2 is reflected by the mirror 11 and received by the light receiving element 4, and the signal is sent to the microcomputer 5 and internally processed. If the microcomputer 5 determines that the number of the selected electronic device 8 matches the number of the microcomputer 5 itself, it sends a signal to the mirror 11 to rotate it. As a result, the light passes through the rear rear window 3 and is sent out to the outside.
Since the light enters the light receiving window 10 of the electronic device 8 and can operate the device 8, the same effect as in the first embodiment can be obtained.

This light emitting element 12 replaces the electronic shutter 6 in the first embodiment and is connected to the microcomputer 5. Note that the other configurations are slightly different from the first embodiment except for the arrangement and the connection state is the same, so a description thereof will be omitted here.

In such a configuration, light incident through the front window 2 is received by the light receiving element 4, and its signal is sent to the microcomputer 5 for internal processing. If the microcomputer 5 determines that the number of the selected device 8 matches the number held by the microcomputer 5, a signal is sent to the light emitting element 12 to cause it to emit light. As a result, the emitted light is
The light is transmitted to the outside through the rear window 3 and is transmitted to the light receiving window 1 of the electronic device 8.
