摘要： An image forming apparatus has an image scanner, a sensor for determining that the image sensor has scanned the front edge of a document, and a controller using main scanning line synchronizing signals and an output signal of the sensor as reference signals. In response to the reference signals, the controller causes at least a writing unit to start writing each image data of particular color and causes a transfer medium driving circuit to start driving a transfer medium. The apparatus allows image components of different colors to be transferred to the transfer medium one above the other in accurate registration.

摘要： An improved image plate scanner (10) for scanning a circular videodisk (12) exposed by X-rays, with image elements (40) spaced a distance (radius R) away from the image plate central point. The image plate is scanned with laser beams. A videodisk carrier (13) on which the image plate is detachably mounted, is drivable with the aid of an electromotor (11), with adjustable rotation speeds. An image element scanning unit (15;115) is radially displaceable across the image plate by means of a drive assembly (14,18) with presettable speed of advance. A laser light supply (42) and an optical image element scanning facility (30a) are parts of an optoelectronic measured value transmission unit, as are a photomultiplier (36) and a signal conditioner. During the light scanning for recording the image stored on the image plate maximum light yield is obtained for the emitted light. The image plate scanner is constructed in a compact manner so as to facilitate operation. The image element scanning unit (15;115) can be guided across the image plate while scanning each image element ( 40) at the same tangential speed, provision being preferably made for the laser light supply (42) to include a collector lens (44), two laser light sources (43a,43b), and an optical filter (46) by means of which the laser light is focussed. The drive shaft (18) of the electromotor (11) is connected by a gear drive to a power spindle (26). The image element scanning unit (15) is translatorily displaceable radially over the image plate (12).

摘要： An image forming apparatus for forming an image by deflecting a light beam signal modulated by an image signal onto a photoconductive element by a polygonal mirror to electrostatically form a latent image and developing the latent image. A main scanning synchronization detector is located in the vicinity of the photoconductive element for setting up synchronization in the main scanning direction. A displacement detector detects a distance over which the photoconductive element has been displaced over a period of time associated with a subscanning pitch. Correcting control is driven in response to the output signals of the main scanning synchronization detector and displacement detector. The light beam signal is so deflected in the subscanning direction as to correct an error in the subscanning pitch.
