Embodiment An embodiment of the present invention will be described with reference to the drawings. First, as shown in FIG. 1, a label printer 1 which is a cutter device of the present embodiment has a structure in which an optical sensor 2, a thermal head 3 which is a printing mechanism, and a cutter mechanism 4 are sequentially arranged on a paper conveyance path 5. As illustrated in FIG. 2, the members 2 to 4 and the pulse motor 6 which is a part of the paper transport mechanism are the detecting means, the calculating means, and the CPU (cutting position control means). Central Processing Unit) 7. The CPU 7 has a ROM (Read Only Memory) 8 in which various information such as programs is recorded and a RAM (Rand).
om Access Memory) 9 is connected.

In such a configuration, the label printer 1
When the label sheet 12 in which the labels 11 are attached at a predetermined interval on the backing paper 10 made of continuous paper is issued without cutting, it functions similarly to the conventional label printer.

Therefore, here, the label sheet 1 is used for the label printer 12
The operation when the label sheet 13 in the form of a cut sheet is issued by cutting the sheet will be described below with reference to the flowchart illustrated in FIG. First, the label printer 1 starts its operation based on whether or not the label sheet 12 is printed or cut. Here, in this label printer 1, as illustrated in FIG. 1A, the distance L between the optical sensor 2 and the cutter mechanism 4 is recorded as known information in the ROM 8 or the like,
When the label sheet 12 passes under the optical sensor 2, the label 11
When the front and rear edges of the label are detected, the CPU 7 detects the distance x of 11 rolls of label based on the detection timing and the number of steps of the pulse motor 6. Therefore, the CPU 7 performs the calculation C = L−x / 2 based on the distance L between the optical sensor 2 and the cutter mechanism 4 and the distance x between the labels 11, as illustrated in FIG. 1 (b). To
The distance C between the center position between the labels 11 and the cutter mechanism 4 is calculated. Here, the data of this distance C is actually the number of steps of the pulse motor 6, and this number of steps is subtracted together with the driving of the pulse motor 6 to obtain the number of steps as illustrated in FIG. 1 (c). When the cutter mechanism 4 is driven at the same time that becomes 0, the mount 10 of the label sheet 12 is cut at the central position between the labels 11 as shown in FIG. 13 will be issued.

By doing this, in the label printer 1,
Since the center of the label sheet 12 between the labels 11 is detected and the backing sheet 10 is cut, the cut edge of the backing sheet 10 coincides with the leading end of the label 11 and the label 11 is difficult to peel off. The tip of 11 is prevented from being cut. Moreover, in this label printer 1, the central position between the labels 11 of the label sheet 12 is detected according to known information and the actual measurement of the optical sensor 2, and it is not necessary for the operator to set a numerical value. The operation is extremely simple and can contribute to the improvement of work efficiency, and at the same time, the occurrence of defects due to an erroneous operation by the operator can be prevented.

When the label printer 1 issues a tag (not shown) by cutting a continuous paper (not shown) in which black marks are continuously provided at predetermined intervals, the label sheet 12 described above is used.
Similar to the detection of the center position of 11 labels, the position of the boundary portion of the tag is detected and cut to issue a tag with good shape accuracy.

And a detection means for detecting the center position between the labels on the label sheet based on the distance between the labels calculated by the calculation means and the distance from the optical sensor to the cutter mechanism,
By providing the cutting position control means for cutting the backing sheet at the center position between the labels by controlling the drive of the cutter mechanism and the transport mechanism, the cut end of the backing sheet of the label sheet cut into a single-cut sheet is set at the leading end of the label. Since it will not be difficult to peel off and the leading edge of the label will not be cut together with the backing sheet, it is possible to prevent defects when issuing a single-cut label sheet. Since the center position between the labels on the label sheet is detected according to the actual measurement of the optical sensor, it is not necessary for the operator to set the numerical value.
