Title: Sheet conveying abnormality detecting method
Inventor: OGATA HIDEICHIRO
IPC: B65H26/02
Filed: 1990-02-05
Abstract: PURPOSE:To detect conveying abnormality without using a sensor by mounting a diode on each of the drive circuits of motors for rollers to convey a sheet in a way that the rollers are alternately the drive side and the follower side, and comparing a voltage between the diode on the follower side and a motor coil with a reference voltage. CONSTITUTION:A sheet 1 is conveyed through alternative drive of rollers 3 and 5 through the medium of guide rollers 2 and 4. When the roller 3 drives, the roller 4 is driven, and the rollers 3,4 are alternately drive or driven side. A diode 13 is mounted on a drive control circuit 10 for each of the motors 7 and 8. When the motor 8 is on the follower side, motor drivers 10b are all brought into an OFF-state, and a generated back electromotive current I0 flows through the diode 13 to a power source (d) after the flow of it through an earth point (a). The waveform of a voltage at a point (b) is changed when the conveying speed of the sheet 1 is disturbed, and the voltage is compared with a reference voltage by a comparator 14 and it is decided that conveying abnormality occurs. Thus, easy monitoring is carried out without using a sensor.

Filed: 1992-01-14
Abstract: PURPOSE:To cancel an increase in an integrated linearity error caused by dispersion in a current of a constant current source cell by switching the constant current source cell discretely in response to a digital input signal. CONSTITUTION:Corresponding to 8-bits, 64 sets of constant current source cells 1 are arranged in a matrix, a high-order 6-bit of a digital input signal is decoded by 3-bit each at decoders 2, 3, and its decode output is latched by latch circuits 4, 5, to apply switching of the 64-sets of the constant current source cells 1. A low-order 2-bit is latched by a latch circuit 6 and a cell subject to 1/2, 1/4 weighting of a current of the constant current source cell 1 is directly switched. In the case of taking a cell subject to 4-bit matrix processing (high-order 2-bit and low-order 2-bit) into account, since a component of the dispersion in the manufacture is observed to be a high-degree component through discrete switching, the integrated linearity error caused by the dispersion in the current of the constant current source cell 1 is suppressed.
