Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a manuscript table that is provided opposite to a camera in a micro-photographing device, and more specifically, for example, when photographing a book or the like on a microfilm, the present invention is applied to The present invention relates to an improvement in a document holder provided for pressing against a document.

BACKGROUND TECHNOLOGY In general, a micro-photographing device is equipped with a camera placed above a manuscript table facing each other, and is arranged to photograph an object while it is placed on the manuscript table. Booklets (especially thick books like encyclopedias) as subjects
When photographing a double-page spread, there is a difference in level on the left and right sides of the double-page spread, and curls occur near the binding margin, making it impossible to photograph the left and right sides of the double-page spread at the same time (double-sided shooting) with one microfilm. This will occur. Conventionally, in order to solve the above-mentioned problems, the document table on which the subject is placed is divided into left and right parts, and both document plates are moved up and down relative to each other to absorb the level difference between the left and right sides, thereby making the left and right sides of the double-page spread the same. A method has been proposed for correcting curls in the portion near the binding margin by aligning the height of the sheets and pressing the double-page spread portion with a glass presser plate.

Problems that the invention aims to solve: However, when the subject is bound in a binder, such as a tax ledger or land register, the binding metal fittings protrude above the double-page spread to hold down the double-page spread. The problem is that it cannot be pressed with a plate, that is, the above method cannot be used. In other words, the problem is that the subject must be removed from the binder and photographed one by one, resulting in a significant loss of work efficiency.

This invention is an attempt to improve the above-mentioned problems, and the purpose of this invention is to take a single photo of the left and right sides of a double-page spread when the subject is bound in a binder. The reason is that it is possible to take pictures at the same time.

The specific means and effects for solving the above problems are as follows.

Means for solving the problem: A presser plate fitted into a rectangular presser frame is divided into a pair of left and right presser pieces, and both presser pieces are slidable along the side edges of the presser frame so that the interval between them can be adjusted. Provided for.

Function: By sliding the left and right presser pieces in opposite directions and adjusting their spacing, it is possible to press the left and right sides of the double-page spread without hitting the binding fittings.

The present invention will be explained below using examples.

Embodiment 1 is a pedestal, and the pedestal 1 is provided with a document table 2 located at the front thereof, and a camera control box 3 located at the rear thereof. A post 4 is erected in the control box 3, and a camera 5 is provided at the tip of the post 4 facing downward, facing the document holder 1. Further, a pair of left and right brackets 4a, 4a are extended in a V-shape with an appropriate downward slope on the post 4, and a pair of left and right illumination lights 6, 6 are mounted facing each other at the tips of the brackets 4a, 4a. .

On the other hand, the document table 2 has a pair of left and right document trays 7,
7 is provided so as to be movable up and down so as to be able to move up and down relative to each other, and a document presser 11 is covered with a document holder 11 so as to be expandable. More specifically, the document table 2 is provided with a screw rod 8 extending in the vertical direction.The screw rod 8 is supported so as to be rotatable via a handle 16. A slider 9 is provided in such a manner that it can be moved up and down through the rotation of the screw rod 8. A pair of upper and lower link rods 10, 10 are pivotally attached to the slider 9 so as to extend in the left and right width directions, and a pair of left and right link rods 10, 10 are pivotally attached to the slider 9, and at both ends of the link rods 10, 10. The document mounting tables 7, 7 are rotatably pivoted.

Further, the document presser 11 includes a presser frame 12 formed in a rectangular shape in correspondence with the document table 2, and a pair of presser pieces 13a, 13a formed using transparent glass as a material.
A pair of support frames 14, 14 each having a U-shaped cross section are attached to the presser frame 12 at both its front and rear edges so as to face each other. More specifically, both support frames 14, 14 are attached by screws 15, 15 that are screwed into both front and rear edges of presser frame 12. Then, when the pair of right and left presser pieces 13a, 13a are inserted into both the support frames 14, 14, both presser pieces 13a,
13a can be slid in both left and right width directions,
Moreover, it is provided so that it can be fixed in any position by tightening the screws 15, 15.

Operation When photographing a document bound in a binder as a subject, the handle 16 is rotated when the document is placed on the document mounting tables 7, 7 in a facing state with an appropriate difference in level. While the document mounting tables 7, 7 are lowered through the operation to absorb the thickness, the screws 15, 15 are tightened in the document presser 11.
Loosen the document presser 11 and slide the presser pieces 13a, 13a in both width directions, adjusting the distance between the presser pieces 13a, 13a appropriately, and place the original presser 11 on the document mounting tables 7, 7. By doing so, a state is obtained in which both facing sides of the document are pressed by both presser pieces 13a, 13a. More specifically, by covering the document presser 11 and pressing the document platforms 7, 7, the document platforms 7, 7 can be moved up and down relative to each other. And the same manuscript table 7,
Through the relative vertical movement of 7, an effect of absorbing the level difference formed between the double-page spreads of the document is obtained, and through this action, both presser pieces 13a, 13a are brought into close contact with the double-page spreads. A state of pressure contact is obtained.

Effects of the invention The invention is constructed as described above.
As mentioned above, the presser plate fitted into the presser frame of the original presser is divided into a pair of left and right presser pieces, and both presser pieces are provided so as to be slidable along the side edges of the presser frame so that the interval can be adjusted. When photographing documents bound in a binder as a subject, it has become possible to press both double-page spreads of the documents bound in the binder with a document presser without being obstructed by the binding metal fittings of the binder.
