Title: Image forming apparatus
Inventor: MORI HIROSHI
IPC: B41J13/00
Filed: 1988-08-20
Abstract: PURPOSE:To maintain a printing speed at an initial state by correcting a sheet feed starting timing and the rotating speed of a sheet feed roller in response to a time in which a recording sheet arrives at a recorder. CONSTITUTION:With the rear end position of a recording sheet P1 as a position D the feeding of next recording sheet P2 is started with the position D as a reference. Thus, if the time in which the sheet P2 arrives at registration sensor pair 12 is delayed 10msec from the initial value, it is so corrected as to set the sheet feed starting timing earlier by 10msec. In the sheet feeding motor rotation controlling process based on a correction value (t), the rotating speed R of a sheet feeding motor 35 is set to a value obtained by multiplying the value of (initial value T1 + correction value t)/T1 by the rotating speed R1 of the initial state, thereby accelerating the rotating speed of the motor 35 corresponding to the delay amount of the sheet feeding speed. Here, in order to determined the correction value based on the decrease in the sheet feeding speed, the total number of printed sheets is first counted, and the correction value is determined on the basis of the counted value. Secondly, a registration sensor 11 is used to measure a time from the start of the sheet feed starting point to the sensor detecting point, and the delay from the initial value is used as the correction value.

Title: Device for detecting double feed of paper sheet
Inventor: ARATA TATSUO
IPC: B41J11/42
Filed: 1985-09-19
Abstract: PURPOSE:To detect a double feed of paper sheets with a high degree of accuracy at a low cost, by providing a parallel-plate capacitor in which two capacitors having the equal capacity are formed. CONSTITUTION:When one paper sheet 2 passes through a gap in a detecting capacitor C2, the electrostatic capacities of both capacitors C1, C2 become equal together, and therefore, the absolute values of both negative and positive output currents are equal together. Accordingly, d.c. voltages applied to a differential amplifier circuit 46 also becomes equal together so that the output voltage of the circuit 46 is zero. However, when more than two of paper sheets 2 pass through the gap, the dielectric constant varies greatly so that d.c. voltages applied to the differential amplifier circuit 46 are shifted to the negative side so that the output voltage of the circuit 46 becomes more than one. A comparator circuit 47 determines that more than two of paper sheets are fed, in accordance with the output voltage of the differential amplifier circuit 46, and then energizes a magnet 5 to open a selector valve 52 so that more than two of paper sheets are discharged, thereby it is possible to prevent such sheets from being fed into a printing process section 6.

Abstract: PROBLEM TO BE SOLVED: To improve precision in discriminating the quality of an AID converter, by reducing an error resulting from the initial value deviation of a resistive potential dividing circuit which generates checking voltage. SOLUTION: A DC voltage where the output of a DC/DC converter 7 is subjected to resistive potential division is taken as checking voltage.
