PURPOSE:To enable to reduce the number of component parts, by a method wherein a type wheel for receipt printing is moved to conduct journal printing, and a selecting trigger electromagnet and the type wheel are used for both printing modes, in a printer for ECR. CONSTITUTION:The type wheels 9 waiting on the journal side are stopped when desired types at respective digit places are aligned, by the rotation of a type wheel driving shaft 11 in response to a printing command and functions of an electromagnet 13,a selecting lever 14 and a returning spring 15 of a selecting means 16. Then, the type wheels 9 are moved to a receipt printing position by moving means 17-22 while being inked by an inking roller 4, and a receipt printing recording paper 8 is pressed by a rotation of a receipt printing roller 6 effected by a driving member 7, thereby printing. Then, the type wheels 9 are returned to a journal printing position, similarly print on a journal printing recording paper 3, and are stopped at a stand-by position by a selecting means 16 through a re-rotation of the driving shaft 11. Accordingly, the number of component parts can be reduced, and reliability can be enhanced. |
