JPH04200198A - Infrared light receiving device - Google Patents

Abstract

PURPOSE:To allow mounting of a remote controller for AV apparatus, etc., at an arbitrary place and to improve operability by forming the light receiving part of an IR remote control as an independent unit contg. a power source as well. CONSTITUTION:The IR light receiving device 20 is constituted as the independent unit contg. the power source 21, such as battery. An IR signal 3 transmitted by an IR remote control transmitter is converted to an electric signal by a light receiving part 4 when the IR light receiving device 20 receives this IR signal. A light emitting part emits light to inform to a user that the IR signal is received when this part receives the above-mentioned electric signal. The IR light receiving device 20 can be freely mounted at an arbitrary place by means of a magnet, double-coated adhesive tape, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a remote control device for AV equipment, etc.

[Prior Art] Fig. 2 shows a schematic configuration diagram of a conventional infrared transmitter/receiver.
10) is an infrared remote control transmitter. The user gives commands using the key operation section (2). In response to this, the infrared signal emitter (1) transmits an infrared signal (3).

(11) is an AV device or the like that operates by receiving an infrared signal.

The infrared signal (
3) is converted into an electrical signal and decoded by a decoding unit (5) composed of a microcomputer, etc. As a result, the AV equipment operates according to the user's command. In order for the user to confirm that the signal (3) has been reliably received, the infrared signal (3)
The light emitting part (6) emits light to notify the user when it receives light.
) may also be provided.

[Problems to be Solved by the Invention] Infrared remote control transmitters generally have directivity, and the distance over which infrared signals can reach is also limited. For this reason, the user must operate the transmitter reliably by pointing it at the AV equipment, etc.
Moreover, you need to get close to it at an appropriate distance.

However, in conventional infrared remote control devices that do not have the light emitting section (6), the infrared signal transmitted when the user operates the infrared remote control transmitter is transmitted to the light receiving section of the AV device, etc. It was not immediately possible to confirm that the above-mentioned light emitting part (6) had been reached. Even though
To enable a user to confirm that an infrared signal transmitted when operating an infrared remote control transmitter has surely reached a light receiving part of an AV device, etc.

[Means for Solving the Problems] The infrared receiving device according to the present invention has a power source independent of the AV equipment etc. to be operated and can be installed at any location, and can be installed in the AV equipment etc. that does not have the light emitting section. Even if there is an infrared transmitter, by attaching it near the infrared transmitter, when the user operates the infrared transmitter and receives the infrared signal, it will emit light to notify the user that the infrared signal has been received.

[Function] The infrared light receiving device according to the present invention is an independent unit with a built-in power source such as a battery, and can be installed and used in any location.

[Example] An example of the present invention is shown in FIG. In FIG. 1, the difference from the conventional example is that there is no decoding section and that there is a built-in power supply section.

The infrared signal (3) transmitted by the infrared remote control transmitter
) is received by the infrared receiver (20) of the present invention and converted into an electrical signal by the light receiver (4). This is converted into an electrical signal. Upon receiving this electrical signal, the light emitting section emits light to notify the user that it is receiving an infrared signal. In addition, this infrared receiver has a built-in battery (21
) is supplied with power.

The infrared receiving device according to the present invention can be freely attached to any location using a magnet, double-sided adhesive tape, or the like.

In the above embodiment, the reception of an infrared signal is notified by light, but sound may be used instead of light.

[Effects of the Invention] As described above, in this invention, the light-receiving part of the infrared remote control is made into an independent unit that also has a built-in power supply, so it can be installed in any location, and when an infrared signal is received, it emits light. AV without sound notification function
Even if it is installed on equipment, etc., by installing it near it,
The user can know that infrared signals are reaching these devices, and can perform reliable remote control operations.

[Brief explanation of the drawing]

FIG. 1 is a diagram showing an infrared receiving device according to an embodiment of the present invention. FIG. 2 is a schematic diagram of a remote control transmitting/receiving section of a conventional device. In the figure, (4) is an infrared signal receiving section, (6) is a light emitting section, (2o) is an infrared receiving device according to the present invention, (21)
has a built-in battery. In addition, in the figures, the same reference numerals indicate the same or equivalent parts.

Claims (1)

[Claims] An infrared receiver that receives an infrared signal transmitted from an infrared remote control transmitter, and when receiving the infrared signal, notifies a user of the infrared remote control transmitter that the signal has been received by using light or sound, An infrared light receiving device characterized in that the light receiving device has a built-in power supply and can be installed at any location.
