Description

[Detailed description of the invention] The present invention relates to a certified copy authenticator.

The purpose is to provide a compact and simple configuration of a certified copy authenticator which authenticates several copies of the original paper by binding them together and punching them in place of a binding stamp, that is, a hole in place of a stamp.

Another object of the present invention is to provide a certified copy authenticator that can automatically create certified copies by being directly connected to a copying machine that copies original documents.

That is, conventionally, authentication work has been performed by inserting a group of sheets that have been copied and bound in advance into a machine, applying a binding verification stamp, and stamping an authentication stamp to authenticate the paper. This conventional authentication device can further save labor in authentication work compared to manual authentication work. On the other hand, it has been difficult to completely automate the authentication process because the work of copying the original paper and binding the copies is done manually.

Therefore, the present invention was created in order to achieve the above-mentioned purpose and completely automate the authentication work, which had been considered difficult in the past. A paper holding plate with a paper edge alignment mechanism is installed behind the drum.
A cutout is formed in this paper holding plate, and a discharge roller is arranged below the cutout to forcefully rotate the paper in order to transport the paper in the opposite direction to the transport direction when the paper passes through the stamping drum. The paper holding plate is arranged so that it can swing freely around its rear end position as a fulcrum to a position where a part of the circumferential surface of the discharge roller protrudes from the notch. A paper ejection lever is provided which swings the paper retention plate through the paper on the retention plate and discharges the paper in cooperation with the ejection roller, and the paper retention plate has a paper ejection swing position of the paper retention plate. A swinging holder is provided to hold the paper, and the swinging holder is provided with a release means for releasing the holding of the swinging position of the paper holding plate at the time of paper ejection, and the paper holding plate is provided on the side of the swinging axis of the paper holding plate. This consists in the addition of a binding device for binding the above group of sheets.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. In the figure, reference numeral 1 denotes a machine frame, and this machine frame 1 is composed of side plates 2 that stand facing each other and a paper conveyance plate 4 that is horizontally disposed between the side plates 2. In this specification, "front" refers to the side of the paper insertion slot 3 that receives paper from a copying machine, etc., and refers to the right direction in FIG. 3.

The conveyance roller 6 is disposed between the paper conveyance plate 4 and a paper guide plate 5 disposed in front of the paper conveyance plate 4. The front conveyance roller 6 is disposed by being mounted on a shaft between the side plates 2 so that the top thereof slightly protrudes beyond the paper conveyance plate 4. Further, a notch 7 is formed near the rear of the paper conveying plate 4, and the top of the platen roller 8, which is horizontally mounted on the shaft between the side plates 2, slightly protrudes from this notch 7.

A stamping drum 9 is disposed above the platen roller 8 and is mounted on a shaft between the side plates 2 and rotates oppositely to the platen roller 8 with a paper interposed therebetween to stamp a stamp. The stamping drum 9 is connected to a motor 12 via a one-turn clutch 11 disposed at the end of a drum shaft 10. Further, in front of the stamp drum 9, an ink roller 13 that contacts the stamp drum 9 and rotates in opposition to the stamp drum 9 is detachably disposed.

Further, above the front conveyance roller 6, a presser roller 14 is provided which rotates while facing and in contact with the front conveyance roller 6. This presser roller 14 is mounted between front swinging frame plates 15 that swing above the paper transport plate 4 using the stamping drum shaft 10 as a fulcrum. By disposing the presser roller 14 on the swing frame plate 15, it becomes easy to take out the paper when it becomes jammed on the transport plate 4.

A rear conveyance roller 20 similar to the front conveyance roller 6 is mounted on a shaft behind the paper conveyance plate 4 .

An upper press roller 21 and a lower press roller 22 are disposed above and below the rear conveyance roller 20, respectively, to resiliently contact the conveyance roller 20 and rotate in opposition to each other.

The upper presser roller 21 is pivoted between rear swing frames 23 which swing around the stamp drum 9 as a fulcrum above a sheet retaining plate 30, which will be described later. Therefore, like the rear swing frame plate 15 described above, when a sheet becomes jammed on the sheet retaining plate 30, it is easy to take it out.

In this way, a paper edge alignment mechanism 50 is provided at the rear of the paper transport path constituted by the transport rollers 6, 20, presser rollers 14, 21, 22, and the paper transport plate 4.

It has a protrusion 47. The swinging holder 45 is also formed to constantly swing in the direction in which the locking protrusion 47 locks on the paper retaining plate 30 due to the elastic force of the coil spring 45A. This swing holder 45 is pivotally attached to the side plate 2 via a swing shaft 49, and the other end opposite to the one end where the locking protrusion 47 is formed is connected to the stamp drum shaft 10. It is engaged with a fixed paper retaining plate return cam 48, and as the swinging holder 45 swings as the paper retaining plate return cam 48 rotates, the locking protrusion 47 is released and the paper is retained. The plate 30 swings upward again due to the elastic force of a spring body (not shown) and returns to its original position.

Therefore, when the solenoid 37 is excited by the paper discharge signal, the locking body 38 swings, and this swing releases the locking body 38 of the paper discharge lever 40, and the elastic force of the coil spring 39 causes the locking body 38 to swing downward. move. Thereby, the paper retention plate 30 and this paper retention plate 30

Bring the trailing edge of the paper into contact with the peripheral surface.

The next copy sheet is also introduced onto the paper holding plate 30 in the same manner as one copy sheet. However, certification stamp 17
Since only the last page, that is, the first sheet of copy paper, is required, the stamp drum 9 does not rotate and therefore no authentication stamp is stamped.

Note that the front and rear edges of the paper are aligned at the same time as the paper is placed on the paper holding plate 30, but after this, the motor 66 of the left and right edge alignment mechanism 50 is turned on to align the left and right edges. becomes. By performing this left and right edge alignment every time a sheet is introduced, edge alignment of the group of sheets can be easily and reliably performed. This alignment of the left and right edges is performed by measuring the elapsed time after the trailing edge of the paper passes over the rear paper detection sensor 91, which is a photo sensor provided just before the rear conveyance roller 20, using a control mechanism. It shall operate when the time is right.

When the front paper detection sensor 90 detects that the number of sheets inputted in advance has been inserted, the binding device 70 operates to drive a staple along the trailing edge of the group of sheets and use it as a counter mark. Drill the holes. Thereafter, the solenoid 37 is energized by the control mechanism, and the paper ejection lever 40 swings downward. This downward swing of the paper discharge lever 40 causes the paper holding plate 30 to swing downward via the paper, and is locked to the locking protrusion 47 of the swing holder 45 to hold this downward swing. . At the same time, the discharge press roller 42 and discharge roller 34 of the paper discharge lever 40 work together to introduce the group of sheets to the abutment area between the rear conveyance roller 20 and the lower press roller 22. The rear conveyance roller 20 and the lower presser roller 22 work together to convey the sheet group into a sheet group receiving tray 18 disposed below the sheet conveyance plate 4.

Note that paper detection sensors 90 and 91 provided close to the transport rollers 6 and 20 are used to count the number of sheets from the copying machine and also to detect paper jams in the transport path.
