摘要:
A set pattern image with no displacement is recorded onto recording paper. In this set pattern image, the centers of auxiliary patterns are displaced in an auxiliary scan direction off a referential straight line passing through the centers of primary patterns. The image forming apparatus causes the set pattern image to be read, measures the displacements of the auxiliary patterns in the auxiliary scan direction off the referential straight line, and compensates for the displacements, such as by adjusting writing timings in the auxiliary scan direction so that the displacements become zero.

The image forming apparatus includes: an image data input section for reading a document as image data; a target value memory section for storing a target value of an input/output characteristic value when a reference document is read; a comparator for comparing the image data of the reference document and the target value so as to create a new input/output characteristic value; a fixed value memory section for storing a difference in input/output characteristic values as a fixed value between an original document and a copy document; and an adder for adding the fixed value to the image data of the reference document so as to output a resultant value to the comparator. By the provision of the fixed value memory section and the adder, the image forming apparatus can set a plurality of input/output characteristic values by reading the reference document once, thus reducing time for the procedure of setting the respective input/output characteristic values.

A control unit inputs a control signal depending on whether reading at a high resolution is selected or reading at a low resolution is selected in an image reading unit. A first delay circuit and a second delay circuit output image data that is captured by a first CCD line sensor and a second CCD line sensor to an adder after retaining the image data for a time in accordance with the input control signal. The adder generates color image data by adding the image data that is captured by the first CCD line sensor to the image data that is captured by the second CCD line sensor.

An image scanning device includes a CCD pair provided with two rows of photodiode arrays for scanning an image on a paper, a motor drive circuit for causing the CCD pair to sub-scan the image on the paper, and an adder for superimposedly combining two outputs of the CCD pair with a predetermined time lag therebetween. A control unit controls the adder to add the two outputs of the CCD pair without the time lag when received an instruction of a low resolution that corresponds to ½ of a high resolution by a resolution switch and thereby doubles a speed of the sub-scan by the motor drive circuit.

Reference images on the respective surfaces of a reference document transported on a transportation path are read out by a first image reading section and a second image reading section, respectively. As a result a first reference readout image and a second reference readout image are acquired. in accordance with the difference between the changes in the sub-scanning direction in the first reference readout image and the changes in the sub-scanning direction in the second reference readout image, the reading cycle of the first image reading section X1 and the reading cycle of the second image reading section X2 are set. This makes it possible to equalize the magnifications of the respective images on the front and back sides of the document, even if the speeds of the document at the times of passing through readout positions for the front and back sides change over time, on account of the wear of a transportation roller.

A display system has a display device, a display control device, and a laser emitting device. The display device has a display part that displays information on a display screen and a laser detection part having a plurality of optical sensors arranged in the vicinity of the display screen of the display part to detect a laser beam that has reached the display screen. The laser emitting device has an instruction input part that inputs an instruction with respect to the displayed information and a laser output part that outputs the laser beam including output information corresponding to the inputted instruction. The display control device has a position calculation part that calculates a position of the display screen irradiated with the laser beam based on positions of the optical sensors that have detected the laser beam, a received information acquiring part that acquires the output information included in the laser beam detected by the optical sensors and a display control part that controls a display of the information displayed on the display part, based on the position calculated by the position calculation part and the acquired output information.
