CONSTITUTION:A storage circuit 1 stores the date data printed on the precceeding receipt and a flag 2 is set up at the issue of the receipt and reset at the printing of one line on the succeeding receipt. When a printing start signal P is inputted under the state that the flag 2 is set up, a comparing means 4 compares the date data of a clock circuit 3 with the date data of the circuit 1 to detect whether both date are coincide with each other or not. At the output of an inconsistency detecting signal S, the receipt is cut off and issued and a receipt cutting and date data printing means 5 prints out date data from the circuit 3 on the receipt to be issued successively. If the date is changed at the start of printing on the succeeding receipt, the date of the receipt to be successively issued is correctly changed. |
