  • Publication number: 20210008909
    Abstract: A cartridge includes: a cartridge case; a first supply portion including a heat-sensitive medium; and a second supply portion including an adhesive medium. The heat-sensitive medium includes a base material, a plurality of heat-sensitive layers, and at least one heat-insulating layer in a stacked state. The heat-sensitive layers include: a first heat-sensitive layer for producing a first color when heated above a first temperature; and a second heat-sensitive layer for producing a second color when heated above a second temperature higher than. the first temperature. The cartridge case includes: an opening for exposing the heat-sensitive medium; and a guide part positioned downstream of the opening in a conveying direction of the heat-sensitive medium for guiding the heat-sensitive medium and the adhesive medium bonded to a surface of the heat-sensitive medium opposite the base material with respect to the plurality of heat-sensitive layers.

  • Patent number: 9550381
    Abstract: A tape cassette includes a cassette case, a tape containment area, a first wall portion, a guide portion, a second wall portion, a third wall portion, and a fourth wall portion. The cassette case includes a top face, a bottom face, a front face, and a pair of side faces. The tape containment area is an area in which a tape roll is accommodated. The first wall portion is provided along a portion of an outer perimeter of the tape containment area. The guide portion is provided downstream from the first wall portion on a feed path. The second wall portion is provided between the first wall portion and the guide portion. The third wall portion is provided on an opposite side of a tape from the second wall portion. The fourth wall portion is provided between the second wall portion and the guide portion.

  • Patent number: 9073346
    Abstract: First fixed value is set as decreasing variable number C and second fixed value corresponding to measured resistance value of a thermal head is determined as constant K(R). Energization of the thermal head is started immediately after start of printing period and the energization is kept until lapse of pulse application time calculated based on chopping duty ratio determined based on thermal head voltage and the constant K(R). Engergization of the thermal head is stopped at lapse of the pulse application time and withheld until lapse of unit time. Calculation value (C(V)×K(TH)) calculated based on temperature and voltage of the thermal head is decremented from the current decreasing variable number C to obtain renewed decreasing variable number C. When the renewed decreasing variable number C is larger than 0, serial processes of calculating pulse application time, keeping and withholding energization of the thermal head are repeated.
