Title: Slip printing paper serial number applying circuit
Inventor: IGAWA HARUO
IPC: B41J25/20
Filed: 1989-06-07
Abstract: PURPOSE:To confirm the omission of a page by applying the continuous serial number corresponding at every printing data per one page at the time of the printing of slip paper. CONSTITUTION:For example, when a power supply is cut off during a period when the image data of the third page is sent to a page memory 2 from a data processing circuit 1, the data of the third page developed on the page memory 2 disappears. When the image data of the fourth page is inputted to the data processing circuit 1 after the power source is re-closed, a count circuit 3 adds 1 to the value of '002' stored in a non-volatile memory circuit 4 to output a value of '003' to the data processing circuit 1 and a serial number is applied to printed paper like '003', '004'... on and after. Since the number of '002' having to be applied to the printed paper of the second page generated by the changeover of the power supply disappears on the outputted printed paper, it can be confirmed whether the omission of a page is generated in this page.
