摘要： A sheet obliquely conveying apparatus is provided with a pair of sheet conveying rollers including a forwardly and reversely rotatable drive roller and a follower roller rotatable in contact with the drive roller, and bearing structure for rotatably supporting the shaft of the follower roller. The dimension of the bearing portion of the bearing structure which supports one end of the shaft of the follower roller is greater generally along the direction of conveyance of a sheet material than the dimension of the bearing portion of the bearing structure which supports the other end of the shaft of the follower roller. The apparatus is further provided with a resilient device generally parallel to the direction of conveyance of the sheet material for pressing the shaft of the follower roller.

摘要： In a disk device, a focus servo activating circuit causes an RF amplifier 3 to amplify a focus error signal within a predetermined gain adjusting range, causes a control circuit 4 to multiply the amplitude of the focus error signal obtained by the RF amplifier 3 by two coefficients to calculate two threshold values, and starts up a focus servo upon the amplified focus error signal passing the two threshold values. The focus servo can be started up normally even for optical disks of extremely low reflectivity.

摘要： A safety device for use in a recording apparatus controls the on/off operation and prevents the malfunction of motors for driving a gear flange to rotate a light sensitive drum and for driving an actuating gear and other driving members in accordance with a signal indicative of the reference rotational frequency received from an oscillator and a signal indicative of the rotational frequency of each motor. A motor control circuit is used including motor drivers for controlling the operation of said motors and a fault detection circuit for detecting the malfunction of said motors by comparing an adder output indicative of said motors' rotational frequencies with threshold values in a comparator, thereby ascertaining the long-term use of the light sensitive drum.
