Abstract: In a paper feed and eject control apparatus for a printer, a printing paper sheet is automatically fed by a paper feed roller through a paper feed guide and is ejected by a paper eject roller through a paper eject guide, both the rollers being driven by a single roller drive motor at predetermined timing. Since the paper feed and eject passages are arranged separately, the paper feed operation will not be disturbed by the paper sheet being ejected, thus realizing a high speed printing operation. Further, the paper feed roller is securely located at the stand-by position without use of an additional control sensor.

Abstract: A paper roll for a thermal printer in which a colouring paper having a thermal colouring layer and a peeling paper on which the colouring paper with the colouring layer is stuck by an adhesive material are wound up into a roll shape is comprised of first cuts for defining a picture forming region of one frame on the colouring paper in order for the picture forming region to be peeled off from the peeling paper and second cuts formed to completely cross the entire width of the paper roll, in which the first and second cuts are repeatedly along the length of the paper of the roll to provide a plurality of picture forming regions.

Abstract: PROBLEM TO BE SOLVED: To provide a meandering preventive device capable of achieving a high meandering preventive effect and a printer capable of printing an image of high quality. SOLUTION: The meandering preventive device and the printer have a guide means for guiding the direction of carrying a belt body, first and second drive rollers mounted in the carrying passage of the belt body, rotating for applying the driving force in the carrying direction to the belt body which is mounted with pressure, a first presser roller with a rotation axis perpendicular to the carrying direction of the belt body, mounted movably in the directions of coming close to/parting from the first drive roller via the belt body, a second presser roller with a rotation axis perpendicular to the carrying direction of the belt body, mounted movably in the direction of coming close to/parting from the second drive roller via the belt body, and a pressure-contact means for pressing the first and second presser rollers to be in contact with the corresponding first or second drive roller alternately.

Abstract: PURPOSE:To prevent printing paper from receiving remaining heat at the time of non-printing upon the contact with a thermal head in a printer wherein the thermal head is displaced to a standby position separated from a platen at the time of non-printing. CONSTITUTION:In a printer wherein a thermal head 12 is displaced to the pressure contact position with a platen 8 at the time of printing and displaced to a standby position separated from the platen 8 at the time of non-printing, a paper bail plate 75 protruding below the thermal head 12 at the standby position is provided on the paper discharge side of the thermal head 12.
