Description

[Detailed Description of the Invention] The present invention relates to a collator for classifying paper such as copy paper or printed paper produced by a copying machine or a printing machine.

Conventional collators have the disadvantage that the operator cannot determine the density of the image on the paper while sorting the paper.

SUMMARY OF THE INVENTION An object of the present invention is to provide a collator that allows an operator to easily determine the density of a paper image during paper classification.

The present invention is characterized by having means for illuminating the image surface of the paper in the paper conveyance path, and a light-transmitting member that transmits light from the image surface of the paper to the outside of the exterior plate of the collator.

The present invention will be explained in detail based on the illustrated embodiments below.

In FIG. 1, numeral 1 indicates an exterior plate,
A paper inlet 2 and a paper outlet 3 are provided at the upper part of the exterior plate 1. A plurality of transport rollers 4 are arranged between the paper inlet 2 and the paper outlet 3, and a guide plate 5 is arranged between the transport rollers 4. The paper 6 entering the exterior plate 1 from the paper entrance 2 is conveyed by the conveyor rollers 4 while being guided by the guide plate 5 with the image side facing up. A branch plate 7 is rotatably arranged so as to be located in a part of the conveyance path formed by these conveyance rollers 4 and guide plates 5.

Below the branch plate 7 are two belt rollers 8.
(The lower belt rollers are not shown) are arranged, and a conveyor belt 9 is attached to these belt rollers 8. This conveyor belt 9 is
The paper guided by the branch plate 7 is conveyed downward.

Near the conveyor belt 9, a plurality of paper storage bins 10 are arranged vertically at predetermined intervals. A deflection means 11 is disposed near the conveyance belt 9 so as to be movable up and down for guiding the sheets conveyed by the belt to a sheet storage bin 10. This deflection means 11 includes two side plates 11a arranged to be movable up and down, a deflection guide plate 11b fixed to a connecting plate provided between these side plates 11a, and a sheet guided by the deflection guide plate 11b. It consists of a paper discharge roller 11c that sends the paper to the paper storage bin 10, etc. A sprocket 12 is provided coaxially with the belt roller 8, and this sprocket 12
A sprocket (not shown) is also arranged below the sprocket, and the chain 13 is attached to these sprockets. A rising sprocket 14 and a descending sprocket 15 are provided on the side plate 11a via a clutch so as to engage with the chain 13.
The driving force of the chain 13 is transmitted to the sprocket 14,
15 and the clutch to the side plate 11a to raise or lower the deflection means 11.

A transparent hole 16 is formed in the upper guide plate 5 located between the paper inlet 2 and the branch plate 7.
A lamp 17 is arranged above this transparent hole 16. This lamp 17 passes through the transparent hole 16 and illuminates the image surface of the paper. A light-transmitting member 18 is arranged near this lamp 17. The light-transmitting member 18 has a lower end facing the image surface of the paper and an upper end located outside the exterior plate 1, and transmits light from the image surface of the paper to the outside of the exterior plate 1. The operator can determine the density of the image surface of the paper through the light-transmitting member 18. The above transparent member 1
8 is made of optical fiber, transparent synthetic resin, etc.

Other embodiments of the invention are shown in FIGS. 2 and 3 and will now be described.

As shown in FIG. 2, light transmitting members 18 may be provided in the holes formed in the exterior plate 1 and the upper guide plate 5, respectively, and the lens 18 may be arranged between them. In this way, the operator can see an enlarged version of the paper image.

The embodiment shown in FIG. 3 includes a light-transmitting member 18 provided in the hole of the upper guide plate 5, and a light-receiving element 20 that receives light from the image surface of the paper through the light-transmitting member 18.
, a density determination circuit 21 that determines the density of the image on the paper based on the output of the light receiving element 20, and a display means 22 that displays the density of the image on the paper based on the output of the density determination circuit 21. In the embodiment shown in FIG. 3, the lamp 17 is
A light shielding plate 23 is provided between the light receiving element 20 and the light receiving element 20 .

Note that instead of the lamp 17, light from outside the exterior plate 1 may be guided into the guide plate 5 to illuminate the image surface of the paper.

The collator of the present invention allows an operator to easily determine the density of a paper image during paper sorting.
