摘要： PURPOSE:To reduce a troublesome operation by a user when a printing ribbon is ordered by detecting a ribbon end no matter whether the trailing end of a printing ribbon is fixed to a pay-out core. CONSTITUTION:In the case of using a printing ribbon 11 not fixed to a pay out core 10 at a trailing end 11a, the trailing end 11a is separated from the pay-out core 10 when the printing ribbon 11 is used up. Thus, a tension member 13 rotates clockwise by the pressing force of a tension spring 17 and drops a shutter member 18 to a detection position under its own weight to actuate a detection sensor 26 to detect a ribbon end. On the other hand, in the case of using a printing ribbon 11 firmly fixed to the pay-out core 10 at a trailing end 11a, the trailing end 11a is not separated from the pay-out core 10 even if the printing ribbon 11 is used up. Then, the tension member 13 rotates counterclockwise against the pressing force of the tension spring 17. The detection sensor 26 is actuated by the tension member 13 to detect a ribbon end.

摘要： PURPOSE:To perform the recording capable of avoiding a possibility of of reading or misreading which may exist when a printed symbol such as a bar code or the like is read by means of an electro-optical technology and to distinguish the printed material having a defect of the recorded result in a recorder utilizing a multi-pass thermal transfer ink ribbon. CONSTITUTION:A verification device 50 inspects whether the recorded result of a symbol such as a bar code which is recorded on a label Ra by means of a thermal head 2 has a defect or not. When the defect is detected, a void indication is formed on the label Ra by means of a void stamper 70. Thereby, the void indication is formed on the label having the defect of the recorded result so that an operator can remove it by judging at a glance. As a result, it is possible to issue a label on which a symbol such as a bar coded or the like that might not cause failure of reading or misreading when being read by means of an electro-optical technology.

摘要： PURPOSE:To constitute the title method so that when a reusable multi-pass heat transfer ribbon is set up once, the device can be managed without resetting the same repeatedly. CONSTITUTION:A quantity of conveyance of a multi-pass heat transfer ribbon 27 which is used by being conveyed in a positive direction at the time of performance of a recording process by a thermal head 2 is returned in a reverse direction at a preestablished fixed rate whenever one unit recording is completed irrespective of usage of the ribbon through a quantity of a rotation of a rotating shaft of a motor 23 turning a ribbon feed shaft 21 measured by a number of pulses of an encoder 25 along with a conveyance ratio of a reverse direction of the ribbon to a used length of the ribbon 27, which is set up arbitrarily by a setting device of a transfer medium reverse conveying rate such as its measured results and a rotary switch. Since the recording is repeated by conveying the ribbon 27 again in the positive direction after that, the ribbon 27 is used up to a possible limit and made throwaway.

摘要： PURPOSE:To eliminate control of defective labels and laborious work for reprinting by a method wherein when defects such as voids and spots are detected in printed contents, the same barcode is reprinted at a printing part on the next label and the defective label is prevented from being peeled off at a peeling part. CONSTITUTION:When an inspection result of printing in a barcode is bad (such as printed contents are very likely not to be read because of voids and spots or to be misread because of too thick or too thin bar widths), the same barcode is reprinted by a thermal head 6 on the next label 3. Further, when a defective label approaches a peeling part 7, a shaft 8 is rotated to retreat a peeling point P by its edge part and change the direction of label paper 1 smoothly along a column surface to feed the label paper 1 to a base paper drawing part 9.

摘要： PURPOSE:To prevent a paper from sagging, by locating a fulcrum for a bail lever on the perpendicular bisector of a straight line connecting between a position A on a platen at which a bail roller is pressed against the platen and an intersection D of a paper in a released position (the position of the paper when the pressing of the bail roller is released) with an involute of the platen passing through the position A. CONSTITUTION:A straight line L is obtained which connects between a position A on a platen 10 and an intersection D of a paper 22 in a released position (the position of the paper when the pressing of bail rollers 16 is released) with an involute of the platen 10 passing through the position A, and the perpendicular bisector l of the straight line L is drawn. A fulcrum P for a bail lever 14 is located on the bisector l. When the lever 14 is turned with the fulcrum P as a center, the bail roller 16 comes into contact with the paper 22 in the released state at a position B on the paper 22 which position is extremely close to the intersection D, and then it is pressed against the platen 10 at the position A. Therefore, the bail roller 16 is pressed against the platen 10 while clamping there between the paper part of the position B at which the roller 16 has come into contact with the paper 22. Accordingly, the paper substantially does not sag in this operation.
