Filed: 1990-07-30
Abstract: PURPOSE:To realize the access time of a high speed by providing a second N-ch L data output transistor between an output terminal and a ground, and suppressing the ringing caused by undershoot of an L data output signal. CONSTITUTION:When L data is outputted, main amplifier output data B2 becomes L, and when main amplifier output data C2 is H, an output control signal A3 becomes H from L, a one-shot pulse A2 becomes H from L by a one-shot pulse generating circuit 5. Subsequently, a second N-ch L data output TR3 is turned on, and the output is varied to an L level from an Hi-z state. Thereafter, when a delay signal A1 of the output control signal A3 becomes H from L, a control signal C1 of an H-ch L data output TR2 becomes H from L, and a first N-ch L data output TR2 is turned on. Accordingly, when L data is outputted, the undershoot quantity becomes small, and ringing can be suppressed.

Title: Original reading device
Inventor: OKADA TAKANAO
IPC: H04N1/04
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To fix an original reading end position in spite of the reading precision of an original by adjusting a time from the detection of the rear end part of the original by means of an original position sensor till the stop of a reading operation by means of a reading part in accordance with feeding speed at the time of feeding the original through the use of an original feeding mechanism. SOLUTION: When the rear end part of the original is detected by the original position sensor 12, CPU 21 reads the corresponding time (pulse number) by present original feeding speed from a memory area where the time (pulse number) till the stop of the reading operation &f8 previously stored, and sets it as the initial value of a step number counter. The step number counter executes count-down whenever a stepping motor 9 executes one step rotation and the original reading operation is ended when the count value becomes zero. The set pulse number is decided by considering a time lag from the removal of the original from the operator of the original position sensor 12 till the actual turning-off of the sensor 12. Thus, the original reading end position is fixed so that reliability is improved.
