Inventor: YAJIMA MASAHARU
IPC: H03M1/06
Filed: 1983-02-21
Abstract: PURPOSE:To control automatically the variation in an analog output current by detecting output fluctuation so as to control a reference current of a D/A converter. CONSTITUTION:The D/A converter 3 consists of a constant current source 4, a D/A converter circuit 5, a voltage detecting circuit 6, a holding circuit 7, and a constant current source control circuit 8. A digital signal is converted into an analog signal at the converter circuit 5 by taking an output of the constant current source 4 as a reference current. The circuit 6 samples a potential difference between terminals of a speaker 9 when a sampling signal is inputted. The circuit 7 holds this sampled voltage value. The circuit 8 consists of an error detecting circuit, detects an error between this voltage value and a preset voltage value and controls the reference current being the output of the constant current source 4 by controlling the source 4 so as to minimize the error. The D/A converter 3 controls automatically the variation in the analog output current with the said constitution.

Filed: 1980-03-06
Abstract: PURPOSE:To automatically strip a ribbon off a form by detecting the end of an ink ribbon and moving a carriage over a prearranged distance with regard to a thermal copying device using a thermal copying ink ribbon. CONSTITUTION:A head 4 is tightly pressed onto a platen 10 through the intermediary of an ink ribbon 11 and a printing form 6 under the rotary effect of a carriage 7 and then printing is performed. Following the shift of the carriage 7, the ribbon 11 is taken up by a take-up reel 15 as it is adhered to the form 6.
