PURPOSE:To simplify and miniaturize a printing mechanism as well as to lessen the consumption of electric energy by providing a type selection mechanism in which a printing wheel is provided to a printing shaft in parallel, types are formed on the peripheral side, and ratchets are formed on the side, and by which a selection lever is coupled with the ratchets through an electromagnetic device. CONSTITUTION:A printing mechanism A having a type selection mechanism B is housed in an outer case 1 in a vertically movable manner. In the mechanism A, a notch 2a and a ringed positioning groove 2b are provided in the flusting direction, and plural printing wheels 3 are set in parallel on the printing shaft 2 in a frictionally following rotation manner. A rock crystal oscillating circuit 33 is used as a standard signal source, and in a time circuit 34, year, month, day, time, minute, and second are counted and supplied to a memory circuit 35. When a lever 14 is pushed down, the printing mechanism A is lowered a push-down detector E is operated and turned on, and the gate of a gate circuit 35a is closed. The types of the printing wheels 3 for each digit are selected by a type selection mechanism B, and the content of the memory circuit is printed. |
