Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a document holder that is provided on the main body of a copying machine so as to be able to swing open and close.

[Conventional technology]

The present applicant has proposed in Japanese Utility Model Application Publication No. 186841/1983 a document holder for a copying machine that simplifies the copying process when the manuscript is a book and has many pages.

The document presser of this copying machine is characterized in that at least one string-like body having a locking member at the end is provided on the document presser main body so that it can be moved in and out and can be wound up. Pull out the string-like body in the open state, wrap it around a double-page spread book document, and lock the locking device provided on the string-like body to the document presser body to hold the book document. Can be attached to the document holder.

Then, lifting the book manuscript and turning the double-page spread upward, and returning the book manuscript to its original position on the contact glass.
Since this is done by opening and closing the document holder, which is inevitably performed during copying, by turning over the pages of the book document during the opening and closing operations of the document holder, it is possible to simplify the copying work of the book document. be done.

[Problem that the invention attempts to solve]

However, with the above configuration, depending on the size of the book manuscript, the troublesome setting work of aligning two adjacent sides of the double-page spread (one side on the left and one sides of the double-page spread and one side above and below) with the document placement standard is required each time. In addition, the set position of the document tends to shift not only horizontally but also vertically each time the pages are turned, or due to the weight of the book document or the swinging of the document holder. It was difficult to make copies in the correct position.

In addition, for example, if a book document is attached with a single string-like member, the document itself will be closed while the document holder is closed, so it is necessary to place your hand on the document when closing the document holder. Furthermore, since the document is closed even when the document presser is opened, there is an inconvenience that it becomes difficult to know which page to copy next.

Alternatively, even when attaching both sides of the document to the document holder using two strings, there is a risk that the center of the double-page spread of the book document may sag and come off the strings, so the document holder must be closed. Sometimes I needed to touch up the manuscript.

In addition, if the pressing force of the book document by the string-like body is too strong, it becomes difficult to lock the locking tool provided on the string-like body to the document presser body. cannot be set too strongly, and as a result, the document tends to sag or shift position while the document holder is closed, and it is necessary to hold the document until just before the document holder is completely closed. That's what I did.

Furthermore, when attaching both sides of the document to the document holder using two string-like bodies, or when attaching the center and both sides of the document to the document holder using three string-like bodies, the original is held down by the string-like bodies. The operation of turning over a sheet of a book manuscript and inserting the manuscript under the string-like body became difficult, and it took time to turn the pages of the manuscript.

The present invention was developed in view of the above-mentioned circumstances, and aims to eliminate all of the above-mentioned inconveniences by using a method for securing documents that is different from attaching book manuscripts using a string-like body. There is.

[Means for solving problems]

The document holder for a copying machine according to the present invention has achieved the above object, and the main body of the document holder, which can swing open and close, is provided with a pair of locking tools that lock and hold the upper and lower edges of the double-page spread of a book manuscript. and a positioning tool configured to allow at least one of the locking tools to be freely changed in position in a distance direction with respect to a document placement reference, and for determining a document placement reference position at one end of the left and right ends of the double-page spread; The present invention is characterized in that the document presser main body is provided with a biasing mechanism that presses the book document toward the contact glass when the presser main body is in the closed state.

[Effect]

According to the above characteristic structure, the upper and lower edges of the double-page spread of the book manuscript are held and held by a pair of locking tools, and the left and right edges of the double-page spread are brought into contact with the positioning tool. By moving the book original to the original position, no matter what size the book original is, it is reliably held at a predetermined position on the original holder.

In addition, with the document presser released, the document is released from the document by the pair of locking tools, and after the page is changed, the document is locked by the pair of locking devices and the lock positioning tool is released. By placing the original against the paper, page turning can be easily achieved while keeping the original position constant.
