Abstract

PURPOSE: To print a passenger ticket and the like without losing time and dislocation in printing by a system wherein a printing start element is set preliminarily at the exothermic element of the printing head enabling to print as feeding the ticket at uniform speed instantly synchronizing with the issue command.

CONSTITUTION: On putting a fare in a slot and pushing a button, a printing command R enters into a printing control circuit 32 and a pulse motor control circuit 31, a printing pulse and a transfer pulse entering respectively into a thermal head 16 and a pulse motor 22. The rotation of the pulse motor 22 causes to drive a draw-out roller 8 and drive also the platen roller 17 of the printing element 5, allowing to feed a tape type heat sensitizing paper 1 and a ticket 4 with a uniform speed. The tape type heat sensitizing paper 1 allows to transfer in a uniform speed at the draw- out section 2. On transferring to the amount of the length L of the ticket, the transfer may be stopped to cut the tape type heat sensitizing paper 1 with a cutter 3 to make the ticket 4. At this point, the printing command R is given to allow the platen roller 17 to start a uniform rotation by interlocking with the pulse motor 22, that synchronizes with the thermal head 16 simultaneously to start printing.
