The drawing distance or position of the punch 30 is constant from the working stand 22.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper connection device, and more particularly, to a long printer paper which is connected to a long printer paper which is creased (and perforated) at a predetermined page size. Paper connection device.

[0002]

2. Description of the Related Art When printing a large amount of bills or the like, a long printer paper is connected in the longitudinal direction so that a printing apparatus can be continuously operated to make the printer paper longer. A paper connection method and apparatus for that purpose are described in, for example, JP-A-53-63118 and JP-A-2788005.

According to the invention described in the publication, the end of the old paper and the start of the new paper are placed on the electrostatic attraction plate in a state where they abut against each other, and the paper connection section where the end of the old paper and the start of the new paper abut. Then, a transparent and printable adhesive tape perforated along the center line is attached so that the perforations coincide with the paper connection portions, and the new and old papers are connected.

As a condition for paper connection, the gazette states that
(1) The property of the paper does not change significantly at the paper connection portion, (2) the fold pitch and fold direction of the paper, and the feed hole pitch of the paper are appropriate (the same is true for new and old paper. ), And (3) the connection part can be printed similarly to other parts.

[0005] The splice jig described in the above patent publication is as follows. That is, the end of the old sheet and the start of the new sheet are placed on the fixed frame 20 in a state where they abut against each other, and the new and old sheets are fixed in the butted state by the sheet pressers 40 and 50 at both ends of the fixed frame. One of the paper pressers 50 is provided with a tape press function that can temporarily press both ends of the paper at predetermined positions. A slide-type cutting mechanism 60 that cuts the adhesive tape 30 is installed in the paper presser 50, so that the adhesive 30 tape can be cut efficiently.

[0006]

All of the conventional examples are based on the premise that printing is performed on the last page of old paper and the first page of new paper in the same manner as other pages. In the case of a mere computer output, there may be no problem if the adhesive tape remains at the end. However, in the case of, for example, a direct mail and a bill, the adhesive tape remaining at the end cannot be used. Conventionally, in order to be able to recognize the page at the end of the sheet, conventionally, a punch hole indicating that the page is related to the sheet connection is formed at an appropriate position on both sides or one side of the sheet connection section. Nothing is printed on the pages on both sides, and they are discarded.

Since the punched holes are optically read in the preprocessing of printing and used to control whether or not to print, they need to be punched at a fixed position on a page. A worker had used a punch to drill holes appropriately by visual inspection. Therefore, not only the workability is poor, but also the punch hole detection range needs to be set wide.

[0008] It is an object of the present invention to provide a paper connection device which solves such a disadvantage.

[0009]

According to the present invention, there is provided a sheet connecting apparatus for connecting a starting end of a creased second sheet of a predetermined size to an end of a creased first sheet of a predetermined size. A pin member which can protrude from a fixed base, penetrates into a paper feed hole provided at an end of the first and second papers at the time of a connection operation, and terminates the first paper. And a pin member for holding the starting end of the second sheet at a position where the starting ends of the second sheet abut against each other, and a sheet holding section for temporarily holding the terminal end of the first sheet and the starting end of the second sheet on the fixed base. Means for making a hole indicating a paper seam in at least one of the last page of the first sheet and the first page of the second sheet. Movable hole making means And wherein the door.

[0010] With such a pin member and the sheet holding means, it is possible to quickly and surely connect with a simple operation in a state where the end of the first sheet and the start of the second sheet abut against each other. Further, the hole indicating the seam of the paper can be formed at a predetermined position by the perforating means. As a result, at the time of printing, printing can be reliably skipped on pages before and after the joint.

By disposing the pin member on at least one side of the first and second sheets, the first sheet and the second sheet can be easily butted, and the first sheet and the second sheet can be separated. Can be placed in a fixed position. By arranging the pin member on only one side of the first call second sheet, it is possible to directly handle sheets of different widths.

Since the pin member is automatically drawn into the fixing base and the sheet holding means automatically releases the first and second sheets, the connection operation can be promptly performed.

By making the perforating means movable in the paper width direction, the perforating means does not become a hindrance except for the paper connection operation.

By using an electrostatic attraction device as a sheet holding member and using it together with a pin member, it is very easy to temporarily hold the end of the first sheet and the end of the second sheet correctly. Paper connection work becomes very easy.
