Abstract

PURPOSE: To prevent the detachment of a lid member from a main body case by providing a support member supporting the end part of an arm under the opening edge part of the main body case in a freely rotatable manner in the vicinity of the inside of the wall of the main body case. CONSTITUTION: A lid member 10 is rotated centering around a fitting part up to the vicinity of a vertical position, that is, a position where a stopper 10c is fitted to a main body case 1 so as to come into contact therewith while elastically deformed and certainly held at this position. In this case, it is characteristic to form the stopper 10c. The leading end of the stopper 10c elastically comes into contact with the recessed part provided to the upper outer surface of an upper case 3 accompanied by the opening operation of the lid member 10 and the lid member 10 is certainly held to the case 3 by the recovery force due to the bending of the stopper 10c. When the lid member 10 is used, the opening height of the lid member 10 is reduced by a distance L and the replacing work of an ink ribbon 8 is easily performed without blocking the visual field of an operator.
