報を得ることができる。FIG. 10 is a view showing a conventional remote control device for an electronic device for transmitting a light beam to space. 10 (a) to 10 (c) show a light receiving section A and a light transmitting section B as a remote controller in one-way communication, and a communication area thereof. The light receiving section A is, for example, an audio or the like. FIG. 10 (a) shows a case in which the light receiving unit A is in the communication area of the light transmitting unit B and communication is possible. FIG. 10 (b) shows that the direction of the light transmitting section B is deviated, and the light receiving section B is shifted from the communication area because infrared rays have a higher directivity and a narrower communication area than radio waves.
Indicates that communication is not possible due to the disconnection. FIG. 10 (c) shows a case where the direction of the light transmitting section B is changed so that the light receiving section A enters the communication area even when the communication area is narrow as in the case of (b). Thus, one-way communication is possible, but the light transmitting unit B may need the information of the light receiving unit A in some cases. Tenth
(D) to (f) show the light transmitting and receiving units A and B in two-way communication and their communication areas. FIG. 10 (d) shows a case where a main body light transmitting / receiving section A for audio or the like and a light transmitting / receiving section B as a remote controller face each other and are mutually communicable areas and can communicate. The light transmitting / receiving section B, which is a remote control, can obtain information on the light transmitting / receiving section A of the main body.

FIG. 10 (f) shows a case where the light transmitting / receiving unit B is directed to the main body transmitting / receiving unit in (e). In this case, the main body light transmitting / receiving section A is located within the communication area of the light transmitting / receiving section B, and the light transmitting / receiving section B can transmit to the main body light transmitting / receiving section A.

域内にないので、本体送受光部Ａから受信できない。受
信可能にするためには送受光部Ｂを本体送受光部Ａに入

領域が狭くなるという問題が生ずる。However, since the light transmitting / receiving section B is not within the communication area of the main body light transmitting / receiving section A, it cannot receive from the main body light transmitting / receiving section A. In order to enable reception, the light transmitting and receiving unit B must be moved so as to enter the main body light transmitting and receiving unit A, which causes a problem that the communication area becomes narrower than the conventional radio wave.

As shown in this figure, the main body light transmitting / receiving sections 3-1, 3-2, 3-
Each of 3 and 3-4 has a communication area within a dotted line shown in the figure. This communication area is formed by concentrating them at one place and arranging them on a horizontal plane so as to form a certain angle with each other in consideration of the directional characteristics thereof. Each main body light transmitting and receiving unit 3-1
3-2, 3-3 and infrared by the light emitting diode D 2 from 3-4 to dotted areas shown respectively progresses. Each of the main body light transmitting / receiving sections 3-1, 3-2, 3-3, and 3-4 receives the light only when the light of the remote light transmitting / receiving section 7 travels from the area indicated by the dotted line toward each. In addition, a slit (not shown) is provided so that the light from the remote transmitting / receiving unit 7 traveling from another dotted line region cannot be received. Therefore, even if the remote transmission / reception unit 7 moves in the horizontal plane, the remote transmission / reception unit 7 communicates with any one of them by directing it to the main body transmission / reception units 3-1, 3-2, 3-3, and 3-4 of the electronic device 1.

As shown in the figure, the remote transmitting / receiving section 7 can communicate only with the main body transmitting / receiving section 3-2 in the communication area within the solid line. However, the remote transmission / reception section 7 can communicate with the main body transmission / reception sections 3-1 and 3-2 if it moves to a portion where the communication area overlaps. In this case, priorities are determined in advance. Communication with one or the other. Thus, the remote transmitting / receiving section 7 and the main body transmitting / receiving section 3

In the figure, a main body light transmitting / receiving unit 3-1, 3-2, 3 is provided in an electronic device 1.
-3 and 3-4 are arranged at regular intervals, and their directions are adjusted so that the respective communication areas overlap. In the overlapping communication area, the remote transmission / reception unit 7 can perform bidirectional communication with any one of the main body transmission / reception units 3-1, 3-2, 3-3 and 3-4 even if the direction is slightly shifted. Thus, the example of FIG.

In this figure, the main body light transmitting / receiving sections 3-1, 3-2, 3-3 and 3-4 arranged centrally in the electronic device 1 in FIG. 12,13 and 14,3-21,3-22,3
-23 and 3-24 and 3-31,3-32,3-33 and 3

For this reason, even if the remote transmitting / receiving section 7 is deviated or moved further, bidirectional communication with one of the main body transmitting / receiving sections becomes possible. Therefore, since a plurality of the light transmitting / receiving sections having a narrow communication area are arranged as described above, the communication area can be widened.

FIG. 8B shows a noise signal of a fluorescent lamp, for example. The fluorescent lamp blinks at 120 Hz, that is, approximately every 8 msec, and emits light with a high cycle of blinking at the time of discharge at A and B in the figure. This light overlaps with the infrared signal of FIG. 8 (a) and becomes electrical noise. After converting the infrared signal into an electric signal, other light is removed through a band-pass filter of signal processing A9, but an electric noise signal of the fluorescent lamp remains. Each light transmitting unit 13-2 of the electrical noise signal strength of the light emitting diode D 2 is the main data processing unit 6, distinguishes the ordinary light by the signal processing unit B10 an electric signal based on the data of the remote data processing unit since flashes the light emitting diode D 2, for example, 38kHz pulse is converted into an infrared signal. The respective light receiving portions 13-1 receives an infrared signal formed by pulses of the 38kHz by the light receiving diode D 1, and amplified by transistor Q 1, the signal processing section A9 from the normal light 38kHz for extracting infrared After passing through a band filter, a rectangular wave is formed by a waveform shaping circuit and converted into an electric signal. FIG. 7 is a diagram showing infrared signals transmitted and received by the light transmitting and receiving unit. FIG. 3A shows an infrared signal of 100 msec transmitted from the light transmitting unit 9 of the remote transmitting / receiving unit 7 to the light receiving unit 13-1 of the main body transmitting / receiving unit through a space at one time. The infrared signal has an identification code at the beginning. This identification code is composed of an A section and a B section as shown. Part A has an infrared signal of 38 kHz at 10 msec, and part B is a blank signal of 20 msec. The time interval is determined so that the data signal can be distinguished from the electrical noise of the fluorescent lamp. After that, for example, data of 8 bits × 5 follows. This data is 0 .0 after a 38 kHz pulse with a width of 0.5 msec.
If there is a blank signal of 5 msec, it is set to “0”, and if it is a blank signal of 1 msec, it is set to “1”. FIG. 4B shows data to be transmitted by the remote data processing unit 8, which is converted into a pulsed infrared signal as described above, and the infrared signal is again converted into an electric signal to process the main body data. 6 indicates the data to be received. Light receiving diode
Reduce the sensitivity of the D 1 but it is also somewhat removed beforehand to improve the S / N in the harsh conditions of varying environmental changes the data as shown in Figure No. 8 (c). Part A in FIG. 8 (c) corresponds to part A in FIG. 8 (b). In this case, since there is a pulsed infrared signal, the electric signal maintains the L signal state and is affected by this noise. Absent. On the other hand, in part B ', the eighth
The portion without the pulsed infrared signal corresponding to the portion B in FIG. 7B must be an H signal. Due to the noise, a part of the H signal becomes an L signal, and the data “1” may become “0” and “0” due to the noise.

イッチ５をオフにする（S6）。FIG. 9 is a flowchart of transmission / reception between the main body light transmitting / receiving section and the remote light transmitting / receiving section. The remote transmission / reception unit 7 converts the data of the remote data processing unit into an infrared signal and transmits the infrared signal (S1). The main body light transmitting / receiving sections 3-1, 3-2, 3-3 and 3-4 receive the infrared signal and convert it into an electric signal. The identification code detection / switch control section 4 monitors the output of the signal processing section A9 of each of the main body light transmission / reception sections 3-1, 3-2, 3-3 and 3-4.
It is determined whether there is a light receiving unit that generates an L signal for 10 msec (S2). When there is no transmission from the remote transmitter / receiver 7, all of its outputs are H signals. When a signal is transmitted from the remote transmitter / receiver 7, one of the output signals changes from the H signal to the L signal according to the A portion of the identification code of the output signal. t 1 = 10 ms
Measure ec. If t 1 <10 msec, this change in output is not due to the transmitted data signal, but to a noise signal. That is indicated on the alarm display section 12 (S7). The identification code detection / switch control unit 4 sets the identification code B to H for 20 msec.
It is determined whether a signal is generated (S3). On the other hand, even when the transmission data signal and the noise overlap, t 1 = 10 msec.
The transmission data signal may include a noise signal. Next, in the case of t 1 = 10 msec, the L signal becomes the H signal by the B portion of the next identification code, so the duration of the H signal t 2 =
Measure 20msec. If t 2 = 20 msec, it is determined that the transmission data signal does not include a noise signal. In this case, the light transmitting / receiving unit and the processing unit 6 are connected via the analog switch 5 (S4). If t 2 <20 msec, it is determined that a noise signal is included. That is indicated on the alarm display section 12 (S7).
Therefore, the processing of the data signal including the noise signal is excluded by the identification code, so that the reliability is improved. The main body data processing unit 6 reads and processes the received data (S
Five). Further, the main body data processing unit 6 includes a remote data processing unit 8
The data is transmitted via the analog switch 5, the main body light transmitting / receiving section 3 and the remote light transmitting / receiving section 7, and after the transmission is completed, the analog switch 5 is turned off (S6).
