Description

[Detailed description of the invention]

TECHNICAL FIELD The present invention relates to a bookbinding device that binds sequentially sent printing paper into a book. Conventional technology iiL Bookbinding 1 in 5 places In A, printed paper is stacked and stacked, and 1-1-machines are used, such as a stapler (a machine that stitches with a letter-shaped needle like Bosotigis). A bookbinding device is known that binds books by using the following methods. In the conventional apparatus, a configuration is used in which the leading ends of the printing paper are aligned by an aligning means, the paper is fed into the finishing stage by a gripping means, and after finishing, it is further pulled out by the old holding stage. In conventional devices, the leading edge aligning means uses an inclined surface to drop the paper and abut it against a stopper. For this reason, it is necessary to provide a separate means for feeding the paper that has been aligned into one level into the finishing machine, and a space is also required to discharge the finished paper, making the machine large and expensive (illi). Moreover, the present invention solves the above-mentioned problems of conventional bookbinding machines, and can effectively and easily perform everything from paper alignment to bookbinding performance and discharge. The purpose of the present invention is to provide a device that has a simple structure and is inexpensive. (2) The structure of the present invention that achieves the above object will be explained based on the embodiment shown in the drawings. In this specification, the expression "printed paper" is printed from II printing press i
1E, it is used in a meaning that also includes a copy ♀IL copied by a copying machine. Furthermore, the expression "bookbinding" is used to mean not only the work of binding multiple sheets of paper together, but also the work of making holes. An example of copying ffj paper using a copying machine will be described below as a representative example. In Fig. 1, a bookbinding device 2 arranged adjacent to a copying machine 1 has a bookbinding device 2 which is arranged to have either a front cover or a back cover or both a front cover and a back cover that are overlapped alternately (hereinafter, for the sake of simplicity, the bookbinding device 2 is arranged adjacent to the copying machine 1) The back cover is indicated by the same symbol - 3). In the feeder section A, the covers 3 are stacked and accommodated on a paper feed tray 4. The paper feed table 4 is rotatably supported by a rotating shaft 5 at −θj;1. In addition to the paper feed table 4, the θ1118 is pressed by a spring 6 toward the paper feed roller rough. Therefore, the cover 3 placed on the paper feed table 4 is pressed against the paper feed roller 7. Paper feed l-1-rough is driven counterclockwise in the figure. The feed xIE roller is supported via a one-way clutch,
When the paper feed roller is placed, the paper feed roller 7 rotates freely so as not to apply any load to the cover 3. Separating means, for example a separating roller 8, is provided near the paper feed roller ruff, and a separating pad 9 is pressed against the separating roller 8 by a rib 10. Like the paper feed roller 7, the separation roller 8 is also supported via a one-way clutch. Adjacent to the separation sealer 8 is a feeding means, for example a pinch roller pair consisting of a lower pinch roller 11 and a lower pinch roller 12. The upper pinch roller 11 is driven by a control section so as to rotate in a counterclockwise direction in the figure, and the lower pinch roller 12 is driven in a clockwise direction.
