Abstract: An image forming system includes: an MFP switchable between a standby state and a power-saving state; a plurality of client computers outputting a print instruction to the MFP; and a server computer managing the MFP and the client computers. To the plurality of client computers, schedule information is input by the users of respective client computers. The server computer obtains the schedule information from the client computers and analyzes the schedule information. Based on the information resulting from the analysis, the server computer outputs an instruction to switch the MFP from the standby state to the power-saving state, to the MFP.

Abstract: To provide a control unit including a touch panel display capable of presenting preview display of multiple pages of document images on the display panel, the touch panel display includes: a binding position indicating controller; a binding process preview displaying controller that displays preview images of recording paper bound at the specified position; a paper binding position-linked scrolling display switching controller that, when the binding position in the printed paper is modified, switches the direction of scrolling preview display so as to be suited to the recording paper bound at the modified binding position.

Abstract: An embroidery stitch data producing device is disclosed, which is superior in its operating efficiency and is effectively operated to produce the stitch data for forming the stitches of an image to be embroidered, wherein the device is adapted to designate the parts of the image in accordance with the embroidering conditions including thread colors and other elements and being optionally determined. The designated parts of the image may be divided into a plurality of groups in dependence upon the determined embroidering conditions, and each of the groups are dealt with as a single unit. The stitch data are produced for each of the units in accordance with the determined embroidering conditions.

Abstract: Disclosed is a device for producing embroidery data on the basis of image data, wherein jump threads extended between unit images are effectively prevented from being stitched into the embroidery stitches by using particular stitch data produced by successively searching the image data from above to set a stitch starting point of each unit image. The stitch data forms the stitches starting from the stitch starting point and terminating at the stitch starting point. Although the jump threads are produced between the stitch starting points, these jump threads will not be stitched into the embroidery stitches.

Abstract: Disclosed is a device for producing embroidery stitch data on the basis of image data, wherein an image is read in by use of an image scanner and is divided into a plurality of latticed sections. The latticed sections are all searched through one after another and discriminated if each of the sections is stitched or not. Unit stitch patterns are selected to be stitched in the sections respectively which have been discriminated to be stitched, the selected unit stitch patterns including at most two patterns which have different initial stitch points and different end stitch points and are located in predetermined sections respectively.

Abstract: An embroidery stitch data producing device is disclosed, which is designed to display an embroidery pattern in a manner that the pattern is closest to the one that is to be embroidered. The device is provided with a scanner 51 or an image input means 2 for inputting colors therethrough. The color indicating data thus obtained and/or color indicating data stored in an image data memory 41 are registered to a color indication data registering means 22. More particularly the area of a display may be set for the background of an image to be embroidered before or after the image is displayed, or before or after the stitch conditions including thread colors are set.

Abstract: Disclosed is a device for producing embroidery pattern stitch data, wherein a pattern or patterns may be entered or selected from a memory (3) and the like and optionally positioned. It is discriminated if the selected pattern or patterns may be wholly received in a predetermined stitch area. If the selected pattern or patterns may not be wholly received in the stitch area and partly extend beyond the stitch area, print data may be produced for printing the selected pattern or patterns, and simultaneously for printing reference marks defining the positions and angles of the patterns relative to the work holding frame for holding the work to be stitched.

Abstract: An electronic zigzag sewing machine is provided with a presser foot including a switch lever pivotable between a first and second position. During buttonhole stitching operation the switch lever remains in the first position, but it is shifted to the second position when either one of longitudinal ends of a buttonhole is detected. A photo-sensor is mounted to the presser foot to output a detection signal when the switch lever is in the second position. A pattern number designating a specific stitch pattern of the buttonhole stitches is renewed to the next in response to the detection signal from the photo-sensor. A control system is provided to nullify operation of the photo-sensor during production of bar tacks of the buttonhole stitches so that the pattern number is not renewed in areas of the bar tacks irrespective of output of the detection signal.

Abstract: A selected pattern display device of a sewing machine is disclosed wherein pattern selecting means is selectively operated to select stitch data for a pattern from a plurality of patterns including a straight stitch pattern stored in pattern storage means, amplitude selecting means is selectively operated to select a numeral value for determining the amplitude of the selected pattern, and display means is provided to display the selected pattern and the numeral value of the selected pattern, discriminating means is responsive to operation of the pattern selecting means to discriminate if the selected pattern is the straight stitch pattern, the discriminating means producing a signal, if the selected pattern is the straight stitch pattern, straight display data storage means is responsive to the signal from the straight stitch pattern discriminating means and a numeral value selected by operation of the amplitude selecting means to produce graphic data representing the straight stitch pattern of a determined n
