Abstract: PURPOSE: To detect the position of a portable transceiver (slave unit) in a radio wave coverage area of a base station for a radio communication device which registers the slave unit kept in the radio wave arrival range in a prescribed procedure and performs the transmission/reception of information. CONSTITUTION: This communication equipment registers a portable transceiver kept in a radio wave coverage area of a base station CS in a prescribed procedure and performs the transmission/reception of information.

If a slave unit exists in the radio wave coverage area, the unit transmits the radio wave to start a registering operation regardless of the operation of a user through the intermittent transmission of radio waves of the station CS. Thereby, the station CS detects the radio wave transmitted from the slave unit by a slave unit detection circuit 110 and knows the position of the slave unit in the radio wave coverage area.

Abstract: PURPOSE:To eliminate a noise bar during high-speed reproduction by providing a switching means which selectively leads out a video signal extracted by a reproducing head or a video signal generated by a pattern generating means in response to the output from a pattern generating means. CONSTITUTION:A second level-detector circuit 255 detects the deterioration of a signal at a prescribed level a little higher than the deterioration level of a signal detected by a level detector circuit 252. The control pulse generator 256 operates in response to the detection by the circuit 255. The generator 256 generates a pulse whose width is a little wider than the part to be regarded as noise. By the signal of such width generated by the generator 256, the second switching switch 257 is switched to a contacting point 257a for the period of said pulse width. Accordingly, the fixed pattern from the pattern generator 254 is outputted to an output terminal 253 during the duration of said pulse width. But during periods other than the above, the output signal from a reproduced video signal switching switch 251 is outputted to a terminal 253.
