IPC: G03G15/00
Filed: 1985-12-24
Abstract: PURPOSE:To recover a normal operating state without giving any troublesome works to an operator even when plural sheets of copying paper are fed at the time of double- face copying, by controlling an original feeding means and picture recording means so that the picture recording can be returned to the original corresponding to the 1st face of the recording material which causes the double-feeding. CONSTITUTION:At the time of double-face copying, a sheet of copied paper is led to a pedestal 200 side by lifting up the flapper 31 of the main body and stored in an intermediate tray 47 through the carrying path of the pedestal 200. When the copying operation is started from the main body 100, an original is fed by a paper feeding roller 51 and led to a carrying belt 54 by a carrying roller 53 and separation roller 52 for preventing double feeding. After the original is set to the prescribed position of the glass surface 26 of the main body 100, the copying operation is started. This recording device is constituted to prevent the double feeding of copying paper in such a way that, when the double feeding is detected, the recording operation is temporarily stopped and a copying key is turned on. When the copying key is turned on, the recording operation is returned to the original corresponding to the 1st face of the transfer paper which causes the double-feeding and the set number of copying sheets is reset.

Filed: 1989-11-10
Abstract: PURPOSE:To guarantee the consecutive recording by detecting a control signal changed in its duty ratio, controlling a capstan motor in order to make a new recording part recorded from the end of the previous recording part and controlling the recording position on a tape. CONSTITUTION:When the tape is rewound into a cassette, a control signal control circuit 8 is controlled by a system control circuit 1, and the duty ratio at the end part of the tape is changed. That is, the change is made for the control signal in such a way that + time(t1   t3) and - time(t2 t4). At the time of reproducing, the capstan motor is controlled by timing for rising + signal in an output of a control signal waveform shaping circuit 10. At this time, when the tape is wound to come under the recording standby state again, the timing for rising one side control signal changed in the duty ratio is detected by the circuit 1 to control a capstan motor control circuit 11, and then the tape is stopped to be under the recording standby state. By this method, the occurrence of a nonrecording part between the previous recording part and the new recording part is prevented.
