Abstract: In an image reading apparatus, a retreat control device moves a conveyance target through a conveyance mechanism, when a stop operation is performed by a stop control device, in an opposite direction to an image reading direction to a position further from a restart reference position set by a position setting unit. A reading control device again moves the conveyance target, which has been moved by the retreat control device, at a constant speed in the image reading direction under a predetermined condition; inputs a line start signal to a reading unit when an offset time set by a time setting unit has elapsed from a time point when the conveyance target reaches the restart reference position; and periodically inputs a line start signal to thereby cause the reading unit to perform a reading operation from a point; where the reading unit is located when the offset time has elapsed.

Abstract: A longitudinally displacable roll apparatus supporting a web (16) of record material is designed to maintain the roll (18) in proper alignment with associated processing equipment as the web is paid from, or wound onto, the roll. The apparatus comprises a pair of frame members supporting the roll. The roll is rotated by a drive shaft (195) having an interengageable coupler on the drive shaft and one end of the roll, to permit the roll to be rotatably driven by the roll drive shaft while not being directly secured thereto. The other end of the roll is engaged by means for displacing it longitudinally in accordance with signals derived from the actual path of the web so as to keep the web accurately on its intended path. The longitudinal and rotational drive system are able to operate independently of each other.

Abstract: A method and apparatus for reducing image unevenness due to light emission of a transfer element. Namely, when a printing speed is changed to 1/2n (n is a positive integer), a SLED head controller repeats a cycle to perform exposure control for one line and then stops the exposure control for the lines corresponding to 1/2n speed. For example, in the 1/2 speed (i.e., n=1), transfer and light emission driving are performed at an initially set maximum speed, and the cycle when the exposure control for one line is stopped after the one-line exposure control is repeated. The printing speed is changed on the basis of the type or kind of recording medium used.

Abstract: An image reading apparatus prevents degradation of image quality and a delay in the image reading time which are caused by interruption of reading of image data. A speed at which a host computer reads image data from an image reading apparatus and temporarily stores it therein is examined. If the resulting speed is lower than a reference value which has been set so that an operation to avoid an overflow of a buffer RAM in the image reading apparatus may not be caused, the sub-scanning speed of the image reading apparatus is set lower, and the image is read at the lower speed.
