Abstract

PURPOSE:To simply discriminate the normality or abnormality of a remote controller by comparing a signal sent from the remote controller with a signal from a normal remote controller stored in advance. CONSTITUTION:A remote controller check device 1 is provided with a reception circuit 2, a comparison discrimination circuit 3, a normal state display circuit 4, and an abnormal state display circuit 4a. Then, a normal remote control signal is sent to the remote control check device 1 and stored therein and a remote control signal from a remote controller 5 being an object of check is sent to the device 1. The sent signal is inputted from the reception circuit 2 to the comparison discrimination circuit 3, in which the signal is compared with the stored normal signal and when the signals are identical, it is discriminated to be normal and a lamp of the normal state display circuit 4 is lighted. On the other hand, when the signals are not identical, it is discriminated that the remote controller 5 is faulty and a lamp of the abnormal state display circuit 4a is lighted. Furthermore, a lamp or a signal tone or the like is selected optionally for the display circuits 4, 4a being the display means.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inspection device for checking the function of a remote control switch (hereinafter referred to as "remote control") of a television, a video, an air conditioner or the like.

[0002]

2. Description of the Related Art The number of electric appliances or industrial machines that can be operated by a remote controller (hereinafter referred to as "remote control device body") is increasing.

[0003]

For this reason, many troubles have occurred due to the failure of the remote controller itself, but normally, it is possible to find the failure of the remote controller itself, except for simple things such as battery exhaustion. Since it is not possible, the failure of the remote control is mistaken for the failure of the remote control device itself, and the number of cases where repair is requested is increasing.

An object of the present invention is to provide an inspection device which can easily determine whether the remote controller is normal or abnormal.

[0005]

The configuration of the remote controller judging device according to the present invention is as follows.

1. If the receiving circuit that receives the remote control signal sent from the remote control, the signal sent from the remote control that was the inspection target, and the signal from the normal remote control that was stored in advance are compared, and both signals are the same A remote controller inspector comprising: a comparison / determination circuit that determines that the comparison result is normal, and if they are not the same, an abnormality, and a display circuit that displays a determination result of the comparison determination circuit.

2. If the receiving circuit that receives the remote control signal sent from the remote control, the signal sent from the remote control that was the inspection target, and the signal from the normal remote control that was stored in advance are compared, and both signals are the same A remote controller control device main body incorporating a remote controller inspection circuit, which comprises a comparison and determination circuit that determines that the above is normal, and that is abnormal when they are not the same, and a display circuit that displays the determination result of the comparison and determination circuit.

[0008]

First, a signal is transmitted from a normal remote controller, received by the receiving circuit of the inspector, and stored in the comparison / determination circuit. Next, operate the remote controller to be inspected to emit this remote control signal, input this signal from the receiving circuit of the inspector into the comparison / determination circuit, and compare it with the normal remote control signal stored in advance, If they are the same, the remote controller determines that they are operating normally and displays normal on the display circuit, and if they are not the same, it displays an error.

The display means of the display circuit is not particularly limited. Therefore, the lamp, the signal sound, etc. can be arbitrarily selected. After the inspection, if the inspection device is a specific remote control inspection device, leave only a normal signal,
Only the signal transmitted from the remote controller to be inspected may be removed to return to the reset state, or in the case of a general-purpose device, all signals may be removed to enter the reset state each time. This removing means is optional such as automatic erasing by a switch or a timer.

[0010]

EXAMPLE FIG. 1 shows an example of the present invention. Reference numeral 1 is a remote control inspection device, 2 is a receiving circuit, 3 is a comparison / determination circuit, 4 is a normal display circuit, and 4a is an abnormal display circuit.

First, a normal remote control signal is transmitted to and stored in the remote control inspection device, and then a remote control signal is transmitted from the remote control 5 to be inspected. The transmitted signal is input from the receiving circuit 2 into the comparison / determination circuit 3 and compared with the normal signal stored therein. If the signals are the same, it is determined to be normal and the lamp of the normal display circuit 4 is illuminated. Lights up. On the other hand, if the signals are not the same, it is determined that the remote controller is out of order, and the lamp of the abnormality display circuit 4a lights up.

[0012]

As described above, according to the present invention, the normality / abnormality of the remote controller can be easily determined. Therefore, when the remote controller itself fails, there is no concern that the remote controller control device body side is judged to be defective. Also, even if there are many types of remote controls that differ for each device, or even if it is a remote controller of another manufacturer,
Each remote controller can be inspected with a single inspection device.

In the case of a television remote control, for example, it is convenient to incorporate a remote control inspection device (circuit) in advance on the television side so that the inspection device can perform a remote control inspection of the television.
