Abstract: A color image processing device uses a dither pattern of blocks, each including a plurality of dots representing the gradations of each pixel of an image in a prescribed print region. The dots including one block are arranged in a growth sequence in the ascending order of gradation, and print data is written sequentially at the dots the number of which corresponds to the gradation associated with the block. An extracting unit extracts a data region holding the color components from the print data. A dither processing unit generates dither patterns for the color components extracted by the extracting unit. The dither processing unit detects whether one or more of the dots including each of the pixels forming the image are outside the data region, and moves any dot outside the data region to a certain dot including the same pixel and existing in the data region.

Abstract: In bookmaking, a sheet bundle is held in a substantially vertical posture. At first an adhesive is applied to a bottom edge of the sheet bundle in a condition that the bottom edge of the sheet bundle and an adhesive application member are pressed together with a first contact pressure to apply the adhesive between the sheets. Then, the adhesive is applied to the bottom edge in a condition that the bottom edge of the sheet bundle and adhesive application member are pressed together with a second contact pressure weaker than the first contact pressure, or are in a non-contact situation.

A counter counts the number of times an unused region in the ink ribbon 41 located in a predetermined position between the supply spool 43 and the wind-up spool 44 reciprocates and shifts between the supply spool 43 and the wind-up spool 44, and when the number of times reaches the predetermined number, the wind-up spool 44 is driven to shift the region in the wind-up direction from the printing position.

Abstract: A sheet feeder includes a delivery roller that contacts a sheet on a sheet supply tray to deliver the sheet; a first detection sensor disposed upstream of the delivery roller so as to detect the sheet on the sheet supply tray; and a second detection sensor disposed downstream of the delivery roller so as to detect a leading end portion of the sheet on the sheet supply tray. The delivery roller is activated in a state where the first detection sensor detects the sheet on the sheet supply tray while the second detection sensor does not detect the leading end portion of the sheet on the sheet supply tray. Thus, all the actually feedable sheets placed on the sheet supply tray can be fed, thereby reducing a sheet setting failure on the sheet supply tray, which reduces trouble of performing a re-set operation.
