IPC: B41J19/18
Filed: 1989-05-10
Abstract: PURPOSE:To inexpensively and accurately feed a sheet by controlling to eliminate abrupt variation in a recording speed in a recording speed determining unit when varying a recording speed in response to an output from a black record counter for counting the number of coloring data of record data. CONSTITUTION:A black record counter 105 counts the number of black or white data to obtain the ratio of the recording part to nonrecording part of record data 101 processed by record data processor 102. If the black data is multilevel data, the multilevel data are added and counted. A recording speed determining unit 106 determines the speed of next record from the data from the counter 105 and the speed of present recording. That is, if there is large difference between the speed of the present recording and the recording speed determined by the data from the counter 105, the speed of the next recording is once set to a value having no large difference from the present recording speed, and the speed is gradually varied. Thus, control in which no abrupt variation in the recording speed occurs is executed to provide an inexpensive and small-sized stepping motor.

Abstract: PURPOSE:To attain writing in blocks and to reduce the access frequencies as well as the processing time of an image memory which is used to a picture processor, etc., by writing a face painting pattern, an oblique line pattern, etc. for each block to a screen memory of (nXn) bits. CONSTITUTION:A pattern data conversion circuit 1 ignores the lower 2 bits of an X address supplied from a terminal A and the lower 2 bits of a Y address supplied from a terminal B in case the block signal of a terminal E is on and the read/write signal of a terminal D indicates a writing mode and transmits the chip selection signal of an image memory 2 which is designated by the high- order 2 bits of the X address supplied to a control line CS from the terminal A. The memory 2 writes the data on a data line WD by the X and Y addresses supplied from a terminal K and a chip selection signal indicated by the line CS. For the chip selection signal of the line CS, the writing position is indicated for every 4 bits in the X direction and also for every 4 bits in the Y direction since the low-order 2 bits are ignored for address in the Y direction. Thus the data on the line WD is written in every block of (4X4) bits.
