Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cylinder for mounting paper such as recording paper or a manuscript in a cylindrical scanning type recording and reading device.

Conventional technology Conventionally, for example, in order to attach recording paper to a cylinder, a second
As shown in the figure, one paper edge 103a of the recording paper 103 is aligned with the score line 102 displayed on the cylinder 101, and the adhesive tape 105 pulled out from the tape holder (not shown) via the guide roll 104 is attached to the recording paper. The end of 103 is attached to the cylinder 101.
After pasting, the adhesive tape 105 is cut on the side of the cylinder 101 by a tape cutter 106 attached to the tape holder. Next, the cylinder 101 is rotated in the direction of the arrow, and the other paper end 1 of the recording paper 103 is
03b to the cylinder 101 in the same manner as above.
05 (this pasting operation is carried out by rotating the cylinder 101 at the pasting work position of the paper edge 103a), and the adhesive tape 105 is cut with a tape cutter 106.

Problems to be Solved by the Invention However, with such a structure, it is difficult to align the paper edge 103a of the recording paper 103 with the marking line 102 on the cylinder 101, and moreover, Therefore, the position of the paper edge 103a is unstable, and the paper edge 103a may also have a wavy shape along that line. Therefore adhesive tape 105
Therefore, it was difficult to attach the recording paper 103, and it was difficult to position the edge of the paper approximately at the center of the adhesive tape 105 in the width direction. Furthermore, even during the rotation of the cylinder 101, the recording paper 103, which is highly rigid, is attached to the adhesive tape 10.
The paper tends to rise from the cylinder 101 against the adhesion force of No. 5, and air tends to enter the paper end 103a facing the rotation direction, which tends to cause the paper to rise. Also cylinder 1
An unnecessary part is generated in the adhesive tape 105 by the length between the end face of the tape 01 and the tape cutter 106, which is not only uneconomical, but also requires cutting off the unnecessary part again with scissors or fingers, or removing the unnecessary part. Adhesive tape 1 is attached to the end face of the cylinder 101 and when rotated.
05 had to be prevented from protruding laterally beyond the end face of the cylinder 101. Furthermore, adhesive tape 10
5 is cut by pressing the tape cutter 106 with a finger when cutting, so a space must be provided between the end face of the cylinder 101 and the tape cutter 106 for the finger to enter, and the pasting work and cutting work must be performed separately. Poor work efficiency.

Therefore, the present invention makes it possible to easily and reliably attach recording paper, etc. to a fixed position on a cylinder, and also eliminates unnecessary parts of adhesive tape, thereby preventing malfunctions and improving economic efficiency. It is an object of the present invention to provide a cylinder for attaching paper, which can be easily cut and tape-cutted, and which can improve work efficiency.

Means for Solving the Problems The technical means of the present invention for solving the above problems is that a groove for positioning the edge of the paper is formed on the outer peripheral surface of the cylinder along the axial direction of the cylinder. is,
one or more tape cutters for cutting an adhesive tape for pasting the edge of paper positioned in the positioning groove in a recess formed in the end on at least one side of the cylinder; The paper is positioned approximately on the central axis of the tape cutter by abutting against the positioning groove in the rotational direction of the cylinder.

Effects According to the present invention, one end of the paper is inserted into the positioning groove, the end is pasted to the cylinder with an adhesive tape, and then the adhesive tape is cut with a tape cutter. After cutting, the cylinder is rotated to wrap the paper around the cylinder, and the other end of the paper is adhered to the cylinder with an adhesive tape in the same manner as above, and then the adhesive tape is cut with a tape cutter. In this way, it is possible to determine the paper edge position and the adhesive tape application position and apply the adhesive tape under optimal conditions. Furthermore, since the adhesive tape is cut at the side end of the cylinder, it is possible to prevent unnecessary parts from protruding, and it is also possible to perform the cutting operation of the connecting tape immediately after the adhesion operation.

Embodiment Hereinafter, an embodiment of the present invention will be described in detail based on the drawings. In FIG. 1, reference numeral 1 denotes a cylinder, and a positioning groove 3 is formed along the axial direction on the outer surface of the cylinder 1, into which one end 2a of the recording paper 2 is inserted. Two sets of notched recesses 4a, 4b and 5a, 5b are formed at both ends of the cylinder 1 in correspondence with each other. One set of recesses 4a, 4b are formed on both sides of the positioning groove 3, and the other set of recesses 5a, 5b are formed slightly downstream in the rotational direction (arrow direction) of the cylinder 1. ing. At least one of the recesses 4a, 4b and 5a, 5b of each set
Tape cutters 6 and 7 are housed in a to prevent danger. These tape cutters 6,
7 is arranged so that its blade portion almost coincides with the edge of the cylinder 1. The positioning groove 3 is located approximately on the center line of the recesses 4a, 4b, that is, approximately on the center line of the tape cutter 6, and the other paper end 2b of the recording paper 2 mounted on the cylinder 1 is located in the recesses 5a, 5b.
, that is, approximately on the center line of the tape cutter 7. Therefore, the recesses 4a, 4b and 5a, 5b also have the function of specifying the tape attachment position.

In addition, the reference numeral 8 in the figure is an adhesive tape supported by a tape holder (not shown), and 9 is an adhesive tape 8.
This is a roller for guiding the drawer.

Next, the operation of the above embodiment will be explained. First, one end 2a of the recording paper 2 is inserted into the positioning groove 3 to completely prevent the end 2a from lifting up and to reliably determine the position of the cylinder 1 and adhesive tape 8. Next, the adhesive tape 8 is pulled out and the paper end 2a side of the recording paper 2 is stuck to the cylinder 1.
At this time, since the grooves 4a, 4b and the tape cutter 6 clearly indicate the optimal position for adhering the adhesive tape 8 to the recording paper 2, the adhesion work can be carried out reliably without requiring any skill. Since the cutter 6 is provided in the recess 4a of the cylinder 1, the adhesive tape 8 can be cut almost at the same time as the pasting operation, and there is no risk of unnecessary parts of the adhesive tape 8 protruding. Next, rotate the cylinder 1 in the direction of the arrow, wrap the recording paper 2 around the cylinder 1,
The paper end 2b is pasted to the cylinder 1 with adhesive tape 8 in the same manner as the paper end 2a side (this pasting work is done at the pasting work position on the paper end 2a side), and the adhesive tape 8 is attached to the tape cutter 7. By cutting the recording paper 2, the work of attaching the recording paper 2 to the cylinder 1 is completed.

Note that tape cutters can also be provided on the grooves 4b and 5b sides.

Effects of the Invention As is clear from the above description, according to the present invention, a groove for positioning the end of the paper is formed along the axial direction on the outer peripheral surface of the cylinder, and a positioning groove is formed on at least one end of the cylinder. A tape cutter is provided for cutting the adhesive tape for pasting the edges of the paper. Therefore, it is possible to prevent the edge of the paper from lifting up, etc., and to securely position it in the cylinder, and the edge of the paper can be easily and reliably attached to the cylinder at a fixed position using the adhesive tape. Further, since unnecessary protruding portions of the adhesive tape can be eliminated, malfunctions can be prevented, and moreover, the adhesive tape can be saved and economical efficiency can be improved. Furthermore, since the adhesive tape can be cut continuously during the pasting operation, work efficiency can be improved.
