Filed: 1998-07-01
Abstract: PROBLEM TO BE SOLVED: To reduce a capacity required for a waveform memory by applying an address generated by an address generator to the waveform memory and outputting the filtered result corresponding to an input data stream from a digital/analog(D/A) converter. SOLUTION: The 32-bit data of input data are converted into parallel data by a serial/parallel(S/P) converter 11a. The respective converted data of preceding 16 bits and following 16 bits become high-order addresses corresponding to waveform memories 21b and 21a. As low-order addresses, both the 2-bit outputs of a counter 12a are applied. The previously found filtered result is written in the waveform memories 21b and 21a. Every time the input data are converted by the S/P converter 11a, the counter 12a counts four clocks and values 0 to 3 are outputted. The outputs of the waveform memories 21a and 21b are added by an adder, the least significant bit is cut and the most significant bit is applied to a D/A converter 30 as a carry output.

Abstract: PURPOSE:To enable favorable correction to be achieved through elimination of an ink present in minute recessed parts by causing a recording head to press against an image-receiving medium with a head pressure approximately equal to that for recording, at the time of correcting a recorded image. CONSTITUTION:At the time of correcting an image, correction data is inputted, upon which a recording head 7 is shifted down, a correcting roller 13 is set down, and a take-up motor 3a and a carriage motor 4d are driven to move a carriage 3 in the direction of an arrow A. A head pressure in this case is set in the range of 800-3,500gf/cm so that a ribbon 2 and a recording paper 9 are pressed against a platen 8 with the head pressure approximately equal to that for recording. With the head 7 brought to the position of an image 14 to be corrected, the head 7 is operated to generate heat selectively, thereby heating the ribbon 2 superposed on the image 14 and adhering the image 14 to the ribbon 2. Thus, at the time of correction, the ribbon 2 pressed is against the paper 9 with a high head pressure approximately equal to that for recording, whereby fibers of the paper 9 are elastically deformed in the same manner as in the case of recording, and a transferred ink present in recessed parts of the fibers is adhered to the ribbon 2, and is released from the paper 9.
