First, data of the page length L of the continuous paper 10 is input by, for example, a ten-key (not shown) of the operation / display unit 4 (S1). The input information of the page length L is stored in the storage unit 2 (S2). Then the actual continuous paper 1
0 is mounted on the tractor unit 12 (S3), the operation unit 4 is operated and started, and the transport unit 8 feeds out the continuous paper 10 by the tractor unit 12 and transports the continuous paper 10 by the transport roller 14 (S4).

The leading end detection signal is taken into the control device 3, and based on the data of the page length L stored in the storage section 2, the control device 3 obtains L2 (= L-L1).
A command is output to the transport roller 14 so that the continuous paper 10 is further transported by the amount and then stopped (S6). Continuous paper 1
0 is stopped, and the continuous paper 10 actually set
If the page length is L, the perforation is located at the detection point of the fold sensor 5, that is, between the opposed openings 13a, 13a (a slight reverse feed is ignored).

Here, if the perforation of the continuous paper 10 is at the detection point position, the upper surface or lower surface is not blocked by the guide plates 13, 13, so that the fold 10 a or 10
The protrusion b is formed and detected by the fold sensor 5 (ON in S8). Based on the ON output of the fold sensor 5,
The control device 3 can confirm that the input information of the page length L is correct, and the printer shifts to a normal printing operation.

（Ｓ１０）。On the other hand, if the page length L is different from the page length of the continuous paper 10 actually used, the perforation is not at the detection point position of the fold sensor 5 as a matter of course (before and after). Position), even if the continuous paper 10 is
In the continuous paper 10 between the openings 13a, 13a, only the bending shown by the dashed line is formed, and the folds 10a, 1
0b is not formed. Therefore, no detection signal is output from the fold sensor 5 (ON in S8). As a result, it is possible to confirm that the data of the page length L has been erroneously input. In order to prevent erroneous operation control of the apparatus, a paper discharging operation is performed (S9), and the operation A warning is displayed on the display unit 4 to prompt re-input of the page length (S10).

The distance from the fold detection point, which is the center of the fold sensor 5, to the tip sensor 6 is the minimum page length A and the reverse feed distance α for the fold detection. , That is, (A + α)
It is as follows. First, when detecting the page length A, FIG.
As shown in (a), when the leading edge of the continuous paper 10 is detected by the leading edge sensor 6, the transport roller 14 is stopped, and the paper is fed backward by α as shown in (b). At this point, the fold 10a is formed at the detection position of the fold sensor 5, and the page length A can be automatically detected by detecting this at the fold sensor 5. In this case, the distance from the fold detection point to the leading edge sensor 6 is made equal to A, not A + α, and the paper is further transported forward by α from the leading edge detection point, and then reversely fed by α, the fold detection The fold 10a can be formed at the point position.

Similarly, when the page length C is detected, as shown in (a) of FIG.
Then, as shown in (b), the page length C can be automatically detected by performing reverse feed by α and forming a fold 10a at the fold detection point position and detecting this.

It is stored in the storage unit 2 in advance so as to operate. Control can be performed such that the detecting operation is performed until a fold is detected for a page having a smaller page length and a page having a larger page length sequentially used in the printer.

1, a leading edge sensor for detecting the leading edge of the continuous paper, a fold sensor for detecting a fold formed at the perforation of the continuous paper, and a predetermined distance from the time when the leading edge of the continuous paper is detected by the leading edge sensor. L2 (= L-L1
Control means for controlling the transport unit so as to form a fold by slightly feeding back the continuous paper while the tractor on the upstream side is stopped after transporting the continuous paper by the amount corresponding to the length of the continuous paper. Page length detector for continuous paper printers.
