  • Publication number: 20230012060
    Abstract: A non-transitory computer-readable storage medium stores an editing program including a set of program instructions for an information processing apparatus comprising a controller and an input interface. The set of program instructions, when executed by the controller, causes the information processing apparatus to perform: acquiring a plurality of strokes inputted via the input interface; calculating a distance between two strokes of the acquired plurality of strokes; in response to determining that the calculated distance is shorter than a distance threshold, recognizing the two strokes as a same item; in response to determining that the calculated distance is longer than or equal to the distance threshold, recognizing the two strokes as separate items; and changing the distance threshold based on input via the input interface.

  • Publication number: 20160209797
    Abstract: An image forming apparatus has an image forming device, a sheet discharge tray, a switchback mechanism configured to reverse a conveying direction of the printing sheet to re-convey the printing sheet toward the image forming device, and a casing accommodating the image forming device. The casing has a discharge opening and a switchback discharge opening through which a part of the printing sheet is projected toward the sheet discharge tray. The image forming apparatus further has a first projection-forming device configured to form a corrugation on at least one of a first printing sheet a part of which is projected toward the sheet discharge tray through the switchback discharge opening and a second printing sheet which is to be discharged onto the sheet discharge tray through the discharge opening, the corrugation having at least one deflection which projects in a direction of thickness of the printing sheet.

  • Patent number: 9305247
    Abstract: In an image forming device, a processor acquires a reference value set for the color combination of two different colors; determines whether the reference value meets an execution condition for correcting misregistration between the two different colors in two image pieces to be superposed one on the other, the determination being performed before forming a finished image including at least a color image portion formed by superposing one of the color image pieces on at least one of remaining color image pieces by using a plurality of image-forming units; forms registration marks for the two different colors in response to determination that the reference value meets the execution condition; and adjusts image-forming positions corresponding to the two different colors subject to correction of misregistration based on outputs of an light-receiving element providing detection results of the position of each of the registration marks.
