Title: Clipping control system
Inventor: NAGAI YASUO
IPC: B41J5/30
Filed: 1984-08-31
Abstract: PURPOSE:To prevent the area interference and to attain the effective processing with a printer having the buffer capacity equal to only one line, by setting just a single area to be compared when the pattern information is developed in terms of an image and absorbing the information into said area in a pre- processing mode. CONSTITUTION:A main memory 8 contains a clipping register and a buffer clipping register. A host CPU1 reads out the stored firmware and controls it to develop the image data into the memory 8. This data is sent to a line buffer in a printer unit 12 under the control of the CPU1 and a micro CPU3. The clipping register is set again in response to the designated value of the software, and the comparison is carried out between said designated value and the present print head area to obtain the optimum value. This value is set to the buffer clipping register and then compared with the coordinate value to be written when an image is developed into the line buffer. In other words, a paper surface area is absorbed by a clipping area and the clipping area is absorbed by a buffer clipping area through the pre-processing. This simplifies a high-speed flow of processing.

Abstract: PURPOSE:To protect the locking of a motor by suitably setting the output pulse width of a monostable multivibrator which inputs the logic product output of a motor drive command and a pulse width control signal, thereby enabling normal and reverse rotation without control of the motor drive command. CONSTITUTION:When a motor drive command MS and a pulse width control signal PS become ''H'' at the starting time, the output Q of a monostable multivibrator 21 becomes ''H'', and a drive pulse OP becomes equal to the signal PS.
