Abstract

PURPOSE: To facilitate the confirmation of the tab position, margin position and the like and prevent errors in the format by providing an indicating means for indicating the tab position, margin position and the like in accordance with a printing pitch.
CONSTITUTION: An indicating device 5 provided for a serial printer comprised light emitting diodes LED placed in all the positions corresponding to the printing pitch of the printer, and lighted intermittently by a driving circuit. In this case, only those light emitting diodes indicated by thick vertical lines are allowed to emit light, LM indicating the left margin position, RM the right margin position and TAB the tab position. To distinguish between the tab position and the margin positions, two-color light emitting diodes are used or different intensities of light are utilized. Other than the light emitting diodes, liquid crystal indicating devices, electrochromic devices, and switch panels or the like may be used as the indicating means.
