  The present invention relates to a printer that prints information on long continuous paper and performs post-processing such as cutting or peeling after printing.

  A continuous roll of labels, each of which is a plurality of labels of a predetermined length on a long mount, is held in a roll shape so that the roll can be rotated, and the label continuous is conveyed and predetermined information is given to the labels. Printers that print are known. Further, the printer is provided with a cutter device, and is configured to cut when a mount portion (scheduled cut position) between the label and the next label is conveyed to the cutter device.

FIG. 8 is an explanatory diagram for explaining the schematic configuration of the printer and the conveying operation of the label continuum after printing. As shown in FIG. 8, a printing unit 90 including a platen roller 91 and a thermal head 92, a fixed blade 93, A cutter device 95 including a movable blade 94 is provided. As shown in FIG. 8A, after the print information 96 has been printed on the first label 71, the label continuous body 97 is conveyed until the planned cut position 98 reaches the cut position (downstream). As shown in FIG. 8B, the movable blade 94 is rotated to cut the continuous label body. At this time, as shown in FIG. 8B, the leading edge of the second label (printing start position) passes through the printing position where the printing unit 90 is disposed, so that the leading edge of the second label is the printing position. As shown in FIG. 8C, the label continuum is conveyed upstream (in the reverse direction) as shown in FIG. 8C, and a head feeding conveyance operation for the next printing is performed. In such an operation, each time a single label is printed, the label continuum must be transported upstream, so there is a problem that the number of labels to be issued per unit time is small and the issuing processing capability is reduced.
As a method for solving this problem, there is known a printer control method in which when a sheet is conveyed to a cutting position, the printing and conveyance are temporarily interrupted to perform a cutting operation, and then the printing and conveyance are resumed (see Patent Document 2). . However, in this control method, there is a problem that the printing quality is deteriorated due to a cause such as the temperature of the thermal head being lowered due to the interruption of printing.
The present invention has been made in view of such circumstances, and an object of the present invention is to provide a printer that enables efficient issuance processing without degrading label issuance processing capability and print quality.

Printer according to the present invention includes a printing unit for conveying the continuous paper having a label which is more temporarily stuck in the longitudinal direction at a predetermined interval in the elongated backing sheet is subjected to printing on the label, conveyed by the printing unit A cutting unit that cuts the continuous paper at the interval position, and when the cutting unit cuts , the cutting unit is arranged so that the interval of the continuous paper is positioned at each of the cutting position and the position where printing is started. And a moving mechanism capable of moving toward the upstream side and the downstream side in the conveyance direction of the continuous paper.
Moreover, to convey the continuous paper having a label which is more temporarily stuck in the longitudinal direction at a predetermined interval in the elongated backing sheet, and a printing unit that performs printing on the label, the label is printed by the print unit mount The separation part is separated from the separation sheet and the separation part is separated from the separation sheet and the position where printing is started at the separation position and the position where printing is started. And a moving mechanism that is movable toward the head.
Further, the moving mechanism includes a rail supported by a printer casing, a guide hole that is inserted through the rail and provided in the cutting portion or the peeling portion, and a fixing portion that is positioned and fixed at an arbitrary position. The printer according to claim 1, further comprising: a printer.

  The cutting unit that cuts the printed continuous paper can be moved by the moving mechanism toward the upstream and downstream sides of the continuous paper conveyance direction, and the continuous paper is cut when the planned cut position of the continuous paper is conveyed to the position of the cutting unit. The distance between the print section and the cutting section can be set arbitrarily so that the print start position of the printer is at the position of the print section, so that continuous paper is moved upstream for the next print head after cutting at the cutting section. There is no need to convey the label, and even if the label has any pitch, the issuing process can be performed efficiently without reducing the issuing processing capability.

  FIGS. 5A and 5B are explanatory diagrams for explaining the cutting operation in the printer. FIGS. 5A and 5B are diagrams for continuous paper having labels with a pitch A having a short length in the conveyance direction of the label (hereinafter referred to as pitch). FIGS. 5C, 5D, and 5E are diagrams showing a printing cutting operation on continuous paper having a label with a pitch B longer than the pitch A. FIGS. In FIG. 5, the printing position is a position where printing starts at the position where the heat generating element of the thermal head 14 is provided. The cutting position is the position where the movable blade 17 contacts the fixed blade 16 and cuts the continuous paper 61. It is a position to do.

  When cutting the continuous paper 61 having a short pitch A label, first, based on the pitch A length information, the cutting part 5 is moved to an optimal position while looking at the scale 27, and the first cutting position is fixed by the fixing part 24. Secure to. With reference to FIG. 5A as an example, the first cut position is a state in which the leading end (interval 64b) of the label 63c with the pitch A arranged on the upstream side on the continuous paper 61 is at the printing position. The position which can be cut | disconnected by the rear end (space | interval 64a) of the label 63a arrange | positioned in the upper downstream is shown. When the cutting portion 5 is positioned at the first cut position and printing is finished on the leading label 63a and the subsequent label 63b as shown in FIG. 5A, an interval 64a is printed at the first cutting position. The space 64b is located at the position, and the movable blade 17 is operated at this position as shown in FIG. 5B to separate the label 63a. Next, the continuous paper 61 is printed on the label 63c without being conveyed upstream, and the above-described operation is repeated.

Next, in the case of cutting the continuous paper 67 having the label of the pitch B longer than the pitch A, the cutting unit 5 is moved while looking at the scale 27 based on the length information of the pitch B as shown in FIG. The first cut position is moved to the second cut position, and the fixing portion 24 fixes the second cut position. The second cut position will be described with reference to FIG. 5C as an example. In the state where the leading end (interval 69b) of the label 68c with the pitch B arranged on the upstream side on the continuous paper 67 is at the print position, the continuous paper 61 The position which can be cut | disconnected by the rear end (space | interval 69a) of the label 68a arrange | positioned in the upper downstream is shown. With the cutting part 5 positioned at the second cut position, printing is continuously performed on the label 68a and the label 68b as shown in FIG. With the conveyance temporarily stopped, the movable blade 17 is operated as shown in FIG. 5E to separate the label 68a. Next, the continuous paper 67 is printed on the label 68c without being conveyed upstream, and the above-described operation is repeated. As described above, since the cutting portion 5 can be moved to an optimal position according to the label pitch, a head-feeding reverse conveying operation for printing is not required at any pitch label. The issue processing capacity is not reduced.
In the example shown in FIG. 5, the interval 64 between the label and the next label is adjusted to the printing position and the cutting position.
