Title: Ink jet printer
Inventor: NAKA TAKAHIRO
IPC: B41J2/13
Filed: 1989-02-28
Abstract: PURPOSE:To correct a dot forming position and to realize printing of high quality by providing a driving circuit for driving nozzles, and delay means for setting a delay time of a print timing signal for driving a nozzle row, and increasing a distance between real nozzle rows as compared with a distance between the nozzle rows to be determined by the delay means. CONSTITUTION:A delay circuit 31 in which a timing signal Ts1 is input generates a pulse print signal delayed at a set time  T1 to driving circuits 21, 22. Thus, since a nozzle row N1 is driven at the delay of the time  T1, a dot forming position is altered at a distance coincident with the moving speed VX TI of a carriage. Similarly, a timing signal Ts2 for driving a nozzle row N2 is delayed at a time T2 set by a delay circuit 32 to form a dot at a reference position. When printing is conducted while moving the carriage in a direction of an arrow 7, the dot by the row N2 is laterally longer than the dot by the row N1, and the position of the center of gravity of the dot does not ride on a straight line. Then, distance l3 between the rows N1 and N2 is increased as compared with the value determined by the delay means to reduce the deviation of the position of the center of gravity, thereby obtaining the dot substantially on the straight line.

Filed: 1988-03-03
Abstract: PURPOSE:To allow a sender side to check whether or not there is any page not sent due to duplicated transmission by returning part of information as to all pages of transmission original to a facsimile equipment at the sender side after the transmission. CONSTITUTION:When the reception of original information is started, at first several tens - several hundreds lines of the information of the 1st page are written in a storage section and the information of the same line number as 2nd, 3rd... pages is written. Thus, when the reception is finished, a part of information of the original of the entire pages sent is stored in the storage section. When the reception is finished, whether or not the signal of return request is reached from the facsimile equipment at the sender side is discriminated. When it is discriminated that the return request signal is reached, the information stored in the storage section is all read and returned. Thus, since the information extracting only part of the initial original is returned to the facsimile equipment of the sender side, it is recognized immediately by checking it whether the original of all pages is reached normally to the reception, facsimile equipment or not reached normally due to duplicate transmission.
