摘要： PROBLEM TO BE SOLVED: To provide device and method for controlling a paper feeding device capable of coping with an abnormal case as much as possible by absorbing dispersion of paper feeding time and expanding a range for making a leading end of a sheet in order.
SOLUTION: In a control device 80 of the paper feeding device, a control circuit obtains an external signal to freely control starting/stopping, speed and acceleration of each motor. The control device 80 is provided with a function 84A to control intermediate speed of a lateral conveying roll 38 corresponding to time when a sheet reaches from a paper feeding start to the lateral conveying sensor 40, and a control function 84B to temporarily stop the lateral conveying roll 38 when time when the sheet reaches the lateral conveying sensor 40 from the paper feeding start is extremely short.

摘要： PROBLEM TO BE SOLVED: To solve the problems in a controller of a paper feeding device that a time (distance) from the arrival at a lateral transport sensor to the stop of the sheet delicately varies because of the difference in paper quality, separating pressure, application of brake and the like when the fed sheet arrives at the lateral transport sensor and stopped, which causes the variation of the time from the start of the lateral transporting operation to the arrival at a longitudinal transporting roller, and impairs the alignment at a sheet bundling position.
SOLUTION: In this controller of the paper feeding device, a paper feeding roller and a lateral feeding roller are driven by motors which are independently controlled, the excess amount (distance) from the arrival of the sheet at the lateral transport sensor to the actual stop of the sheet is determined on the basis of a position/speed pulse synthesized by a signal of a magnetic pole position detector of a brushless DC motor, a correction time of a lateral transport start timing determined by inverse calculation on the basis of a rotating speed of the lateral transporting roller is added to or subtracted from the standard start timing to determine the optimum lateral transport start timing.

摘要： PROBLEM TO BE SOLVED: To reduce the induction noise of an FG (frequency generator) and to reduce the size of it.
SOLUTION: The surface of a printed wiring board that faces an annular magnet end face is a front surface. An FG coil composed of radial line elements is disposed on the front surface, while a circular cancel coil is disposed on the rear surface of the printed wiring board. By arranging the cancel coil on such rear surface of the printed wiring board as of a diameter close to the average diameter of the inner diameter and the outer diameter of the FG coil, the disturbance inductive noise that penetrates the printed wiring board vertically is canceled while miniaturization is intended.

摘要： PROBLEM TO BE SOLVED: To install a speed sensor that detects the speed of a gear reduction shaft by an inexpensive constitution, and to reduce the irregularity of rotation, by solving the problem that, in a method for conducting speed control by installing a speed sensor to an output shaft of a gear reducer, it is expensive to employ an encoder or the like for the sensor, and an assembling man-hour is increased since a dedicated part is necessary for wiring or the like even if an inexpensive speed sensor is employed, thus allowing the use of an expensive sensor. SOLUTION: A cylindrical magnetic drum that is multipole-magnetized at its external periphery is fixed to an output shaft of the gear reducer at a side opposite to a direction wherein a printing drum is coupled. On the other hand, the MR sensor is directly mounted on a printed wiring board of an iron system base material on which a control circuit of a motor is constituted, and arranged so as to oppose the magnetic drum with an adequate air gap therebetween. The speed sensor is directly mounted on the printed wiring board that constitutes the control circuit, and thus the connection between the speed sensor and the control circuit is eliminated. Since the printed wiring board employs the iron system base material, an SN ratio with respect to disturbance noise is raised. COPYRIGHT: (C)2005,JPO&NCIPI
