Tele-male unit

PURPOSE:To enable tansmission and reception with one unit and to avoid the performance of writing tools from being lost. CONSTITUTION:The selection switches 38 and 39 are connected to the transmission side contacts 40 and 41, and letters are writtin on the lower sheet 13 with the writing tool 11. The signal from the signal radiator 12 is detected with the detection heads 16 and 16', and control is made with the signal following circuits 46 and 47 so that the outputs of the both heads 16,16' are made equal. The motors 24, 26 are driven with the drive circuits 44 and 45, the recording head 17 of the detector 15 is followed beneath the radiating body 12, and the head 17 draws letters on the recording paper 14. The signal detected with the head 16 is A-D converted with the circuit 48, and each output of the X,Y axis position detectors 28 and 32 is wave shaped at the circuits 36 and 37, is coded at the transmission signal control circuit 49 and is transmitted to the telemale unit at a remote location. At reception, the motors 24, 26 are driven with the reception signal control circuit 50 and circuits 44 and 45, the signal is transmitted to the head 17 and the output is controlled. The output of the detectors 28,32 is fed back to the motors via the circuits 36 and 37, allowing correct following.
