Title: Picture coder
Inventor: KATAYAMA AKIHIRO
IPC: H04N1/415
Filed: 1989-12-21
Abstract: PURPOSE:To reproduce a character part with high quality, to prevent production of ringing and to save a high frequency component by applying BTC coding to the character part including much high frequency component and taking a difference between the BTC decoding picture and an input picture. CONSTITUTION:An input picture data inputted from a picture input section 1 is discriminated as to whether it is a character part or not for each block by a classification section 2 and the block discriminated to be a character is given to a BTC(Block Truncation coding) section 3, where the pattern is expressed as one bit and a difference P1-P2 being a difference between mean values P1 and P2 is coded. A BTC decoding section 4 uses signals 101, 102 to reconstitute the picture and only the character block is reproduced. A differential device 5 takes a difference between the reproduced picture and the input picture and its output is coded at a DCT(discrete cosine transformation) coding section 6. Thus, a character part including much high frequency component is coded by the BTC to eliminate the high frequency component thereby preventing production of ringing.

Abstract: PURPOSE:To enable high-speed and high-quality printing by simultaneously driving a plurality of printing blocks with the aid of a driving means according to a simultaneous current feed pattern preset on the basis of the distribution of electric heating elements per dot. CONSTITUTION:In the case where an MPU 1 receives a printing command from a host computer through an interface circuit 5, printing data of a one-dot line unit are expanded on an RAM 7. If the latch operation of the preceding dot line in a thermal head 9 is completed, signals of the printing data expanded on the RAM 7 are sequentially transmitted to a printing rate measuring circuit 3. In the printing rate measuring circuit 3, the number of heating resistance elements to which a current is fed are counted in a printing block unit and the printing data are temporarily retracted on the RAM 7 while the printing data synchronized with a transfer clock are transferred to a shift register in the thermal head 9. When the transfer and the like of all the printing data on the one dot line are finished, the following operation starting trigger TRO is issued from the printing rate measuring circuit to a printing block determining circuit 4 to which a current is fed.

Since this nip point R is installed in the opposite direction of the paper feed roller 41 with a tangent A at the paper feeding forefront end of a surface slidingly contacting with the paper feed roller 41 of the pad 46, the sheet G held and tensed by the nip point R acts so as to separate the pad body 45 from the paper feed roller 41, but the pad body 45 has some play and is supported by a supporter, so that it acts so as to strongly narrow the sheet admission side. Thus, a separation property of the sheet is improvable.
