摘要： When a print line is printed on a printing paper by supplying a print current to a thermal head, heating elements within the thermal head and a transfer ribbon are easily adhered together due to melted ink on surface of the transfer ribbon. Due to such adhering between the heating elements and the transfer ribbon, a white line is easily formed on a printing paper. In order to prevent such white line from being formed, the heating elements must be prevented from being cooled down after printing each print line. More specifically, in a period between a first time when each print line is completely printed and a second time when a printing paper is to be transported forward to a next print line, the heating elements are heated by relatively small heating value which is sufficient to melt a adhering portion formed between the heating elements and the transfer ribbon but which is insufficient to perform the printing. Thus, the heating elements are prevented from being adhered to the transfer ribbon, so that each print line can be printed with accuracy and without forming the white line.

摘要： A thermal printing system of this type is able to obviate loosening of the paper sheet stock during its feeding step prior to printing, and thereby to prevent crumpling of the paper and information of misaligned print from occuring. A thermal printing system capable of performing aforesaid function can be achieved by making the printing system as such one comprising, a platen, a pair of pinch rollers one end of each of which is rotaably supported by each one of a pair of pinch roller levers and is resiliently biased by a pinch roller lever tensioning spring so that each pinch roller can be brought into tight contact with aforesaid platen, and a paper stock holding cassette case attached with a paper feed roller for feeding paper stock for printing, in which the peripheral speed of the platen is set higher than that of the paper feed roller of the paper holding cassette. By virtue of this improved construction, the feed roller attached to the paper holding cassette is utilized as a type of brake means for imparting back tension for the purpose of stretching the sheet of paper being fed.

摘要： Each of the parts or components constitutes the thermal head holder is designed to be small in size, thin thickness and having such a shape as can be readily fabricated by press forming of metal sheet or by moulding plastic material, in addition, the thermal head supporting means as a sub-assembly is attached to the central part of the rotary shaft so that it can be supported in a manner of one point central support type suspension.Depression of the thermal head utilizing this supporting means against a platen roller is performed by urging, relying on cam action, a thermal head urging lever having a length considerably shorter in axial direction and very light weight, thereby the depression can be applied to the platen of a thermal printing system via a depression spring disposed at the central part of the thermal head holder and normal to the aforesaid rotary shaft and in a central support type manner.

摘要： In a thermal printing system having an automatic paper feeding mechanism paper may be misfed and become crumpled between one of a pair of spring biased pinch rollers and the platen of the printing machine. A mechanism is provided for automatically releasing pressure between the rollers and the platen, wherein a depression/release lever is provided with a cam disposed between supporting members of the pinch rollers, and the lever is actuated when a frame of the printing machine is raised to provide access to the machine, causing the cam to widen the space between the pinch rollers and the platen so that the crumpled paper can be easily removed.

摘要： A printing system for a boarding pass and/or a baggage tag comprises an operating unit; a housing; a control unit in the housing receiving instructions from the operating unit; and two printing units in the housing controlled with the control unit. One printing unit includes: a roll of printing paper strip; a feeding mechanism for drawing out the paper strip; guide members for the strip; a dotting printer for printing characters on the strip; a cutting unit for cutting the strip after being printed; and an ejecting mechanism for ejecting the printed and cut printing paper strip as a boarding pass or a baggage tag from the housing. The other printing unit includes: a roll of a second printing paper strip, and a similar feeding mechanism, guide members, dotting printer, cutting unit, and an ejecting mechanism for ejecting the printed and cut second printing paper strip as a baggage tag from the housing. In addition, the other unit includes: a roll or an adhesive tape consisting of a tape base, and double-sided adhesive pieces and cover pieces, which are substantially equal to each other in size, and constituting adhesive members, and the adhesive members being attached at regular intervals on the tape base; a stripping member for stripping the adhesive members; a take-up mechanism for taking up the tape base from the tape roll; and an attaching mechanism. One of the adhesive members is stripped from the tape base by the stripping member, to be attached at the adhesive surface of the adhesive member to the back of the printed and cut printing strip as the baggage tage by the attaching mechanism when the tape base is intermittently taken up by the take-up mechanism.
