PURPOSE:To enable a printing start position to be visually determined easily with the extremely accurate setting of a printing start position without generation of a parallax by providing a light emitting device which emits light to a printing start position for display. CONSTITUTION:A printing start position display device 16 consists of a light emitting diode 21, a beam case 17 for holding the light emitting diode 21 in storage and a bracket 23 for supporting the beam case 17. The beam case 17 moves with a printing head 14 in a single body, and the shaft core of the beam case 17 is arranged at a height corresponding to an almost intermediate part of the vertical width of a platen 6. If the light emitting diode 21 is energized, it emits light 33, and part of the light 33 is emitted to an area outside the beam case 17. The light is condensed into a directional flux through a photoconductive orifice 18 and a photoconductive cell 19. Subsequently, an almost circular spot light 33a is projected to a sport opposite to the platen 6 of a printing sheet 10. Printing starts at a position where a spot light 33a is emitted. |
