Image Number 5 for United States Patent #5649248.
In order that data indicating the allocation of ports for controlling light-emitting devices or the start year and the end year of a calendar can be arbitrarily rewritten, an imprinting control unit includes a calendar control unit for calculating the time and date, an imprinting output control unit for outputting imprinting patterns to an imprinting unit in order to perform data recording, and a memory. The calendar start year and end year data and the imprinting output patterns stored in the memory can be rewritten into arbitrary data through a communication line. This allows easy changes in the wiring to the imprinting unit and in the calendar specifications.
