Abstract: PURPOSE:To increase the function, by mixing the voice signal and the text code signal together and recording them on a recording medium. CONSTITUTION:The input signal given from a keyboard 1 is coded through a process circuit 12 and stored in a memory 15 through a circuit 14. While the voice signal supplied from a microphone 7 is supplied to a recorder 3 in the record mode. This voice signal is then supplied to the circuit 12 when the record switch of a switch 4 is pushed. Then a command given from the circuit 12 is supplied to a control circuit 19 to obtain a record mode. The signal is supplied to the circuit 12 with push of a reproduction switch of the switch 4. Then a reproduction mode is set to the recorder 3 via the circuit 19 and by a command from the circuit 12. Thereafter, the voice signal is announced from a speaker 6 and through an amplifier 18.

Abstract: PURPOSE:To reproduce data by digital processing entirely by detecting a digital data signal rising by a window pulse which corresponds to a rise to a level H. CONSTITUTION:A window pulse 39 and a synchronous detection signal from a detecting circuit 38 are supplied to an AND circuit 40 to extract the window pulse 39 while the synchronous detection signal is at a high potential. Then, the extracted pulse 39 and an input signal 44 are supplied to a data detecting circuit 41, which detects data 1 when the input signal rises within the range of the window pulse 39 or data 0 when not, thereby obtaining data at an output terminal 42. Since this is performed entirely by digital processing, noise resistance characterstics are improved, the influence of temperature drift, etc., is lessened, and the variance due to temperature characteristics is reduced.

Abstract: PURPOSE:Any correct position on the television screen pointed by a light pen will be detected even though some time lag may be caused by the light pen and each detecting circuit.
