Definitions

  • FIG. 1 is a schematic diagram for explaining a main configuration related to printing of the thermal printer 100 according to the first embodiment.
  • the X, Y, Z coordinate axes shown in FIG. 1 correspond to the X, Y, Z coordinate axes of FIGS. 3, 4, and 5.
  • the ink sheet 1 shown in FIG. 1, the paper 2, and the paper roll 2a in which the paper 2 is wound in a roll shape are not included in the thermal printer 100.
  • the thermal printer 100 mounts the ink sheet 1 and the paper roll 2a, and uses the ink sheet 1 to print on the paper 2 drawn from the paper roll 2a.
  • the ink sheet 1 is obtained by applying an ink material made of a dye to a heat-resistant plastic film.
  • the heights of the left and right head pressures shown in FIG. 6 are by design, and with such a configuration, when the head pressure deviates from the design in the actual thermal printer 100, the head pressures are made uniform on the left and right. It is possible to make adjustments.

Abstract

L'invention concerne une imprimante thermique qui détecte sans contact l'état d'une feuille d'encre. Dans une imprimante thermique selon la présente invention, une unité d'émission de lumière et une unité de réception de lumière d'au moins un capteur optique sont placées de telle façon que l'unité de réception de lumière reçoit une lumière de signal qui a été émise par l'unité d'émission de lumière et a traversé la feuille d'encre.
