Title: Document producer
Inventor: SAKAKIBARA ATSUSHI
IPC: B41J21/00
Filed: 1985-07-05
Abstract: PURPOSE:To reduce an operational load on a document producer by changing and setting formats just with a single key operation. CONSTITUTION:A keyboard KB includes format setting keys K1-K3, an input/ editing key group K4 and a print key K5. When one of keys K1-K3 is operated, a CPU sets a flag F on a RAM to another flag showing the corresponding format together with a document storing area 4 set to the corresponding formats 33-31. Then the set format is displayed on a display device DIS via a display register DR. The areas 33-31 start at the same address with the maximum number of digits (42 characters) of a A4 size defined as a block. When the format displayed on the device DIS is changed, the corresponding keys K1-K3 to be changed are operated to perform the similar setting procedure. Thus the format can be changed and set just with a single key operation. In such a way, the load on an operator is reduced.
