摘要： PURPOSE:To prevent the tip of printing paper from becoming crimped and caught erroneously and ensure the positive catching of the tip of the paper between platen pressing rollers by controlling the positions of the paper, a carriage and the pressing roller so that these positions are moved as specified. CONSTITUTION:Prior to a normal line feed accompanied by a printing action before the tip of printing paper 15 reaches a holding position, a carriage 20 is moved to a position where a paper guide 22 is offset to the side from below a pressing roller 26. Then when the tip of the paper 15 is set to a position corresponding to the holding position in the forward line feed mode, the paper 15 is reset in the backward line feed mode by setting the pressing roller 26 to a released state. After that, the paper 15 is set back to the holding position in the forward line feed mode, and the pressing roller 26 is closed to press the paper 15 against a platen 11. Subsequently, the tip of the paper is prevented from becoming crimped and at the same time, from failing to be caught correctly. In addition, the positive holding of the paper 15 between the platen 11 and the pressing roller 26 is ensured.

摘要： PURPOSE:To easily and effectively remove the slack of a continuous sheet generated when the continuous sheet is mounted and to smoothly feed the sheet by reversibly returning the sheet from a pin tractor of a downstream side toward the pin tractor of an upstream side only by the tractor of the upstream side. CONSTITUTION:A microcomputer 41 is provided as control means for controlling the operation of a sheet feed motor 37, and stores in advance the control program of the motor 37. The microcomputer 41 reversibly drives the motor 37 at a predetermined amount to return a continuous sheet P at the predetermined amount. Thus, the rotary motion is transmitted to a pin tractor 28 of upstream side through gears 34, 35, 38. In this case, its returning distance is so determined as not to remove the sheet P from a pin tractor 12 of a downstream side and to slightly reversibly rotate the tractor 28 upon returning of the sheet P and to be larger than the positive feeding distance. As a result, tension is applied to the sheet P to remove its slack.

摘要： PROBLEM TO BE SOLVED: To provide an ink jet printer having nozzle arrays fixed to a carriage while being divided into more than one head in which positional shift of dots from nozzle arrays provided in different heads can be reduced. SOLUTION: A first set value for adjusting dot shift by software is read out from an EEPROM 11 (S2) and interlace conditions between heads for determining how much a recording sheet is shifted in the sub-scanning direction from the print position of a reference head at the time of printing with the other head is set (S5). Based on a content which is set based on the first set value, interlace is executed between heads and printing is conducted while performed normal interlace (S7-S12).

摘要： PROBLEM TO BE SOLVED: To provide a facsimile terminal that suppresses a noise caused at printing by conducting printing at a speed lower than a conventional speed under a prescribed condition. SOLUTION: When a value of a mode memory is set to '2' (S3:2), a low noise mode is set to a home mode. A 'half speed' is stored in a passive area of a home mode area other than those for 9:00-22:00. Data of RTC are read to check a current time and when the current time is other than 9:00-22:00 (S5: No), a drive speed of a carriage motor and a recording paper carrying motor is set to a half of a conventional speed in order to print out image data received by facsimile data at a low noise (S6). On the other hand, when the current time is within 9:00-22:00 (S5: Yes), since it is not required to print out the image data received as the facsimile data at a low noise, the drive speed of the carriage motor and the recording paper carrying motor is set to the usual speed (S2).

摘要： PURPOSE:To clamp the leading end of a paper between a pressure roller and a platen without damaging the leading end, by separating a pressure roller from a platen by moving a carriage upon input of a paper-feeding signal before the leading and of a printing paper reaches a position between the roller and the platen. CONSTITUTION:After the leading end of a printing paper is brought to a position between a platen 2 and a printing head 13 by feeding the paper and before the leading end reaches a position between a pressure roller 5 and the platen 2, the roller 5 is separated from the platen 2 by oving a carriage 12 to an end part of the platen 2 prior to a paper-feeding operation when a paper-feeding signal is inputted. Therefore, even when an error in the leading end position or an error is generated by a feeder in insertion of the printing paper, the leading end of the paper is securely brought to the position between the roller 5 and the platen 2, and the paper is clamped between the roller 5 and the platen 2. Accordingly, before the leading end of the paper is clamped by the pressure roller, printing on a leading end part of the paper can be performed without any trouble.

摘要： PROBLEM TO BE SOLVED: To prevent a printing dot row from exceeding a printing rear end part and at the same time utilize a printable area to a maximum, by providing a control means for changing a paper feed amount corresponding to a data development position shift and a controlling means for carrying out printing by a printing head in accordance with printing data. SOLUTION: In the case of one-pass printing, if printing data of a printing dot row D2 is detected to exceed a printing rear end position L of a paper, a data development position is shifted so that the data does not exceed the L, and also a paper feed amount is changed corresponding to the shift. In the case of two-pass printing, the data development position is shifted so that printing data of rows D5, D6 do not exceed the L, and the paper feed amount is changed corresponding to the shift. A printable area is accordingly utilized to a maximum to a position of the vicinity of the printing rear end position L to print the printing data.

摘要： PURPOSE:To reduce the number of components of an operating member and to decrease a manufacturing cost by switching switching means to a cut sheet using position and a continuous sheet using position to operate a sheet retaining roller, a power transmission mechanism and a changeover switch. CONSTITUTION:A sheet feeder can simultaneously perform switching disposition of a sheet retaining roller 5 for feeding a cut sheet or a continuous sheet, switching of setting power transmission to a platen 2 and a pin tractor 14 and further switching to set a signal output from a changeover switch 33 corresponding to cut or continuous sheet feeding relatively to each other by the operation of one switching lever 32. As a result, a sequence of switching to set the cut or continuous sheet feeding can be reduced, the number of components of an operating member, etc., required for operating another changeover switch can be decreased and a manufacturing cost can also be reduced.

摘要： PURPOSE:To prevent step-out of a step motor from occurrence, by a method wherein a signal by which reverse rotation is performed by the total of a set feed amount containing a self start-up area having followed at first a self start-up program when a return command is received and a feed indication amount from a host apparatus is outputted to a reverse rotation control part and then, a signal by which normal rotation is performed by a set feed amount is outputted to a normal rotation control part. CONSTITUTION:When a transfer indication in a return direction is received from a transfer amount input part 15, a return transfer part 20 reads each program from a memory part 16, and prepares a driving pattern of a step motor 5. At first, a setting feed amount (a constant value) is added to an indication value from the transfer amount input part 15, and a self start-up area and an accelerating area following it are set to an initial part of the total amount following a self start-up program and an accelerating program. Further, a decelerating area is set to a final part following a decelerating program. A return transfer part 20 outputs a reverse rotation signal to a reverse rotation control part 17 following the driving pattern. The return transfer part 20 successively outputs a normal rotation signal by a set feed amount to a normal rotation control part 18 containing the self start-up area having following the self start-up program in its initial part.
