JPS5953352A - Conveyor for the original - Google Patents

Abstract

PURPOSE:To eliminate the contamination or damaging of a sheet and prevent its wrong conveyance, by providing a turner for turning an original holder, and a mover for moving the holder and the turner. CONSTITUTION:As soon as the turning of an arm 11 is started by a motor 15 for turning holding plates 1, 2 these plates are opened from each other. A conveyor for the original P then starts moving forward as a whole. The original P pinched between the holding plates 1, 2 is conveyed in a direction E and then stopped in a position for reading the original. After the reading, the arm 11 is turned up and the original P is conveyed again in the direction E and reaches a position for discharging the original. In the discharging position, the arm 11 is turned by a prescribed angle and the holding plates 1, 2 are opened from each other to drop the original into a tray 60.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a device for conveying notes such as copy paper, transfer paper, and C-copied originals, and particularly to a device for conveying notes such as copy paper, transfer paper, and C-copied manuscripts, and in particular for conveying notes in copying machines, electronic files, facsimile machines, printing machines, etc. In order to reliably transport one sheet at a time, hold the sheet 1.42 and press 1.
Regarding the device f that transmits 1G.

<Prior art> Conventionally, as a device for conveying sheet-shaped paper or document paper material one by one to a predetermined position, there is a device that conveys sheets of paper or manuscript materials one by one to a predetermined position. It is common and widely used to transport sheet materials one by one by sandwiching them between a pair of rollers.

Devices using this pair of rollers utilize the friction of the rollers to carry out conveyance. Therefore, it is easy to damage the document material (original) and stain the surface of the document. It is easy to slip against the paper, and it is also easy to cause slippage during conveyance due to a decrease in the coefficient of friction caused by changes in paper dust and roller particles over time.Meandering caused by unbalanced roller shapes during the conveyance process It has many disadvantages such as easy occurrence.

Therefore, in order to eliminate these drawbacks, air suction q(-
A variety of devices have been proposed that utilize air suction to absorb all of the sheet material and transport the adsorbed sheet material. Adsorption ↑11! I is connected to a suction air goose song that has a negative pressure chamber inside, and one side of the sheet material is sucked and spread by the bottom surface of the sheet material adsorption section, and a belt provided on the bottom surface or (-i roller, etc.) is used to absorb friction. It is configured to convey the material while being in contact with one side of the material that has been attracted by the rotation of the part. For example, if the suction force is too strong, it will be easy to damage the particles, and if it is too weak, it will be easy to make a mistake in suctioning the particles. Even if thick sheets, IJ, etc. are used (
Not only is general feeding difficult (ξ11), but even compared to the case where a pair of rollers is used, there is a high risk of meandering because the sheet material is not pressed from both sides like a pair of rollers.

On the other hand, sheet conveyance devices in which driving parts such as chains are directly connected near both sides of the document gripping part have also been provided, but due to constraints from the driving devices such as chains, they are small and have high precision. It is difficult to provide such equipment.

<Object of the Invention> In view of the above-mentioned drawbacks, the present invention aims to provide a compact and highly reliable document conveying device that does not stain or damage the notebook, and does not cause conveyance errors. There is.

<Embodiment> The document conveying device of the present invention will be described in detail below with reference to the drawings showing an embodiment of the present invention.

FIG.
The f view and FIG. 2 are explanatory diagrams for explaining the operation of the present invention. Identical parts have the same symbol '(r= (=Jshi).

Reference numeral 12 in the figure indicates a base plate of the document conveying device, and this base plate 1
Two frames 13 are provided on top of the frame 13 to support the grip plate rotating shaft 14 via a bearing material (not shown).

A worm wheel 19 for driving is attached to the gripping plate co-moving 'l'llll + 4, and this foil 19
1 is attached to the output 41+ of the grip plate rotating motor ■5, which is mounted on the motor mounting plate 25.
8 is engaged. On the other hand, the grip plate rotation shaft 14 is provided with an arm 11 for fixing the main support column 3 that supports the grip plates 1 and 2ff, and the position of the ground 11 is the rotation axis of the grip plate in AiJ. It is determined based on the iris number from the sensor (not shown) by the swimming ring 16 attached to the arm 11 on the opposite side to the worm 18 and the worm foil 19. ! The rotation and stop of the 11 old/ν part in the direction of the arrow in the figure, which is locked at fL, is based on the signal from the sensor by the tide/geslit 16 of the motor 15 for rotating the coffin plate. (Patency 1) Performed by driving fL. Then, the main column 3 attached to the arm 11 is connected to the V-shaped gripping plate 11W ("J BO, 7, the document gripping plate 1 is inserted through the 4") block 5 and the block. One gripping plate 2 is provided on the original side through a bearing 4'A26 provided on 7L-C.

This is done by the operation of the solenoid 10 attached to the plate 27, and its rotation angle is constant. Reference numerals 7 and 8 in the figure indicate the original to be held. This is a sensor for detecting end noise.The entire device constructed as described above is connected to the slider 20 provided at the bottom of the plywood 12 and the slider 20 provided inside the slider 20 via the bearing +7128 provided at t1. 171.
On the opposite side, two sets of rollers 21 attached to legs 22 or a rail 24 (not shown) are moved on the opposite side.
It is configured to run in the direction of arrow E in the figure by means of a drive transmission wire 23 due to the action of a seven-movement motor.

Next, the operation of the document conveying apparatus V of the present invention constructed as described above will be explained with reference to FIG.

FIG. 2 shows the steps of a document reading device as an embodiment using the document conveying device [6(r) according to the present invention.

In Figure 2, reference numeral 50 indicates the upper surface of the platen glass, reference numeral 55 indicates a document suction device that pulls up the document I' to a predetermined paper feeding position by, for example, air suction. ≠ indicates a tray, P indicates a sheet-like original to be conveyed, and P' indicates original+7:f, the original accommodated in the accommodation tray 60.

When an instruction is given to start reading the original, the original suction device 55 pulls the original I) to the fixed paper pickup position F9r shown in FIG. 2(a). At this time, the document suction device 5 is in the standby position and is not in operation.
After confirming that the document P to be conveyed has been lifted up by the arm 1, as shown in FIG.
