  • Patent number: 10173364
    Abstract: A blade of a cutting tool is stuck into a medium adhered on a support member and is stopped in a state in which a blade edge is positioned between upper and lower surfaces of the medium. A cut line is formed in the medium by the support member and the cutting tool being moved. The blade is pulled out from the medium. An embossing tool is pressed against a position along the cut line of the medium. A continuous recess extending along the cut line is formed in the medium by the support member and the embossing tool being moved.

  • Patent number: 10011034
    Abstract: A cutting plotter includes a driving roller, a rotating shaft, pinch rollers, a cutter, and a press roller. The driving roller extends in a direction of a first axis and rotates around the first axis. The rotating shaft extends in a direction of a second axis parallel to the first axis, and is configured to be rotatable around the second axis. A passage through which a cutting target passes is formed between the driving roller and the rotating shaft. The pinch rollers are provided on the rotating shaft. The cutter is selectively pressed to the cutting target. The press roller is provided on the rotating shaft between the pinch rollers, and presses the cutting target against the driving roller. The press roller is formed by a coil spring into which the rotating shaft is inserted.

  • Patent number: 9694507
    Abstract: There are provided a shape data generation apparatus and shape data generation program capable of arranging, on one sheet-like medium, parts obtained by slicing one cutting shape. A shape data generation apparatus includes a slicing unit (11) configured to slice a cutting shape represented by supplied shape data into a plurality of parts in accordance with a closed shape prepared in advance, an arrangement unit (12) configured to arrange, of the cutting shape, a part protruding from the closed shape to fit in a free space within the closed shape, and a generation unit (13) configured to generate shape data representing a plurality of parts fitted in the closed shape.

  • Patent number: 9574998
    Abstract: A line segment detection apparatus includes a head that supports a sensor configured to detect light reflected by a surface of a cutting target medium, a driving unit configured to move the head in two-dimensional directions relatively to the medium, and a processing unit configured to drive the driving unit and perform arithmetic processing on an output of the sensor. The processing unit includes a region detection unit configured to detect a region different in reflectance from surroundings based on a change of a signal output from the sensor when the sensor was moved in a first direction, and a determination unit configured to determine whether the region is a line segment, based on the change of the signal output from the sensor when the sensor passed a point in the region and was moved in a second direction perpendicular to the first direction.

  • Patent number: 9519255
    Abstract: The provided is an electrographic type label printer to properly supply a roll paper to the printer, having a transfer portion of a toner image, a fixing portion, an unwinder that feeds a roll paper, a rewinder that takes up the roll paper, a conveyance mechanism, and slack detection sensors that detect a slack degree of a medium between the transfer portion and the fixing portion. The conveyance mechanism has a conveyance belt to be rotated while mounting the medium on an upper surface facing the upper side, and an intake mechanism for tightly fitting the medium to the upper surface of the conveyance mechanism. When selecting a mode to convey the roll paper, a paper feed unit controller controls passing speed at which the medium passes through a pass-through portion provided in the fixing portion in accordance with output signals from the slack detection sensors.
