  • Patent number: 5791218
    Abstract: In a cutting device having a moving (disc) cutter and a fixed cutter which extends in a cutting direction, wherein the moving cutter moves along the fixed cutter, thereby cutting a medium which is interposed therebetween, a presser member which is movable together with a medium pressing interlocking plate is lowered to press on the medium to fix the same at a portion close to a cutting position since a bearing attached to the moving cutter engages with the medium pressing interlocking plate to press down the same as the moving cutter moves. Since the moving cutter cuts the medium at this state, the cut edge of the medium can be excellent in linearity even if it has low rigidity in the outward-surface direction at right angles to the surface thereof. While the moving cutter does not cut the medium, the presser member is retracted to a standby position.

  • Patent number: 5700096
    Abstract: In a printer for printing on a recording medium using a transfer medium, a transfer medium capable of being repeatedly used at the same portion thereof (e.g., a multi-pass thermal transfer ribbon) is conveyed in the normal direction in performing the printing process by a recording means such as a thermal head etc. and the conveying amount of the transfer medium which is used for printing is measured at that time. The transfer medium is conveyed in the reverse direction by a given amount based on the result of the measurement and the reverse direction conveying ratio of the transfer medium to the used length of the transfer medium which is arbitrarily set by a transfer medium reverse direction conveying ratio setting means irrespective of the used amount of the transfer medium every time a unit of printing is completed. Thereafter the transfer medium is conveyed in the normal direction for printing.

  • Patent number: 5678938
    Abstract: A thermal printer that prints on a recording sheet by holding the recording sheet between a thermal print head and a platen, driving the thermal print head to generate heat and driving the platen to feed the recording sheet comprises an approach limiting means that limits the approach of the thermal print head to the platen and determines a minimum distance between the thermal print head and the platen. The approach limiting means is provided with a stopping member for stopping the thermal print head or a print head holding member holding the thermal print head moving toward the platen to limit the approach of the thermal print head to the platen and to determine a minimum distance between the thermal print head and the platen. The thermal printer reduces the bias of distribution of the pressure of the thermal print head on the recording sheet along the width of the same and is capable of printing characters and the like clearly over the entire width of the recording sheet.

  • Patent number: 5531530
    Abstract: In a printer comprising a printing means for performing printing on a continuous paper in response to a print data and a cutter unit for cutting the continuous paper in the paper width direction upon completion of printing, a printed paper needs to be sorted out easily and clearly depending on jobs. To meet the demand, the printer is provided with a rotary blade and a fixed blade which cut the continuous paper in the paper width direction which crosses perpendicularly to the paper feed direction and it is further provided with a carriage for holding the rotary blade so as to be movable in the paper width direction. The carriage has a shading piece. Sensors are disposed at the position corresponding to the position where the cutting amount of the paper in the paper width direction is set to be smaller than the entire paper width. When the sensors detect the shading piece, the rotary blade stops moving to thereby stop the cutting operation.
