Printer

Abstract

Abstract PURPOSE: To simplify the construction of the printer and miniaturize the printer by detecting such information as the kind, the tail thereof and the like of an ink ribbon by a single detecting means. CONSTITUTION: A detector 9, for example, a reflection type photointerrupter is provided for sensing the tail end of the ink ribbon and discriminating the kind of the ink ribbon. When an ink ribbon case 4 is stationary below a printing position, the detector 9 can discriminate the kind of the ribbon through a kind-detecting part 4b, so that it controls the number of pulses fed to a pulse motor. On the other hand, during a printing operation, the case 4 is pushed upwards, so that an information source for detection is shifted to a port 4a, and the conditions of the ribbon are detected through the port 4a. When the ribbon is fed and a silver foil at the tail end part thereof appears in the port 4a, the detector 9 delivers the information to a controlling circuit, thereby stopping the printing operation swiftly.
