| PROBLEM TO BE SOLVED: To provide inexpensive equipment where an angular range of automatic tracking is extended with a simple configuration and an automatic tracking function with a fast response is provided. SOLUTION: A transmission signal is received from an input terminal 38, amplified by an amplifier 37, converted into an optical signal by a light emitting element 34, passes through an optical transmission system 33 and a polarized light beam splitter 32 and is sent to opposite equipment in the form of a light beam via a moving mirror 31 and a transmission/reception lens system 30. On the other hand, a received signal from the opposite equipment is made incident from the transmission/reception lens system 30, reflected in the moving mirror 31 and reflected in a stuck surface of the polarized light beam splitter 32 and collected by a signal light detector 36. Then the electric signal converted from the optical signal by the photodetector 36 is amplified by an amplifier 39, and outputted from an output terminal 40 as a received signal. Furthermore, the signal of a detection circuit 41 is given to a control circuit 42, where the signal is used for detecting received power, and the control circuit 42 gives a drive signal to variable mirror drivers 43a, 43b based on the signal. Simultaneously an output signal from the detection circuit 41 is used for automatic gain control of the amplifier 39. COPYRIGHT: (C)1999,JPO | ||||||

The photo detector 50 detects information received optically and the photo detector 80 detects a matching error of the transmitter-receiver. Thus, no light interference between lights received by the photo detectors 50, 80. COPYRIGHT: (C)1998,JPO | ||||||

| PROBLEM TO BE SOLVED: To attain reception independently of the direction of signal communication equipment by reflecting an IR signal passing through an IR signal reception port of a magic mirror in a reflecting board and the magic mirror and receiving the reflected signal by a signal light receiving section. SOLUTION: An IR signal 4 from the inside of a receiver 1 passes through an IR signal reception port 2 made of a magic mirror, repeats reflection at the point (a) of a reflection board 3, the point (b) at the reception port 2, the point (c) of the reflection board 3 again, and then the point (b) at the reception port 2 again and then received by an IR signal reception section 5. Even when the IR signal 4 is made incident from the part other than a side face of the receiver 1 having the light receiving section 5, the reflection board 3 formed at a corner of the receiver 1 is chamfered, then the IR signal 4 bypasses the other side faces and reaches the side face with the light receiving section 5. Thus, the IR signal is received independently of the incoming direction of the IR signal 4. COPYRIGHT: (C)1997,JPO | ||||||
