JPS6150132A - Original retaining device - Google Patents

Abstract

PURPOSE:To hold well thick originals as well as thin originals by connecting one end of a pair of links freely vertically turnably to both end faces of an original retaining cover and connecting the other end of these links freely vertically turnably to the fixed side. CONSTITUTION:When a thin original A is copied, a receiving piece 10 is attracted to a magnet 11 to fix a link 6, and an original retaining cover 5 is vertically turned around a pin 7. At this time, since the link 6 is held and the original retaining cover 5 is not turned together with the link 6, the operation is easy. When a thick original B is copied, the receiving piece 10 and the magnet are separated from each other when the original retaining cover 5 is pressed to the thick original B, and the link 6 is turned upward around a pin 9, and the original B is retained surely.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a document holding device for holding down a document set on a document holding table of a copying machine or the like.

Conventional technology A document holding device in which a document holding cover is connected to the main body of a copying machine etc. with a pin so that it can move up and down.

A document holding device in which a document holding cover is vertically movably connected to a mounting base that is removably attached to the main body of a copying machine.

Problems to be Solved by the Invention With the former device, when copying a thick original such as a book, the original cannot be pressed against it, and if it is forcibly pressed, it will be damaged.

The latter device is convenient when copying large-sized originals, but it is troublesome as it requires removing and attaching the number υ each time.

Means and Effect for Solving Problems The other end of a pair of links which are vertically movably connected to both end faces of the document holding cover is connected to the fixed side so as to be vertically movable, and a magnet is mounted opposite to this link. It is fixed on the fixed side and rotates the link upward to press thick originals, holding the link with a magnet to press thin originals, and allows the original to face between a pair of links to print large-sized documents. The original is pressed against it.

Embodiment FIG. 1 is an overall perspective view. An opening 3 is formed in the upper wall 2 of the main body 1 of the copying machine, and a document support 4 such as a platen glass is attached to the opening 3. This document holding table 4 is opened and closed by a document holding cover 5.

A pair of links 6.6 are provided on one side of both end surfaces of the document holding cover 5.
One end is supported by a pin 7 so as to be movable up and down, and the other ends of the pair of links 6 and 6 are pivotally connected to a bracket 8 by a pin 9 so as to be movable up and down. In addition to being fixed to the upper wall 2 of the copying machine main body 1, receiving pieces 10 are fixed to the pair of links 6 facing outward, and a magnet 11 is attached to the copying machine main body 1 facing each receiving piece 10. The reeds and receiving pieces 10 are fixed to the upper wall 2 respectively, and the magnets 11
When the original holding cover 5 is attracted to the original holding table 4, the original holding cover 5 moves up and down with respect to the link 6 about the pin 7 to open and close the original holding table 4.

Therefore, when copying a normal size and thin document A, as shown in Fig.
It is sufficient to fix the slider 6 by suctioning K and move the document holding cover 5 up and down around the pin 7. At this time, link 6
Since it is held, the document holding cover 5 does not rotate together with the link 6, and its operation is simple.

When copying a thick original B of normal size, when the original holding cover 5 is pressed against the thick original B as shown in FIG. rotates upward around pin 9, so
The pin 7 can be displaced upward, and the thick original B can be held securely.

In addition, when copying a large-sized, thin original C, as shown in Fig.
This allows you to copy the original without folding it.

Effects of the Invention By rotating the slider 6 upward, the connecting portion between the document holding cover 5 and the link 6 can be displaced upward, and it is possible to press a thick document without damaging it, and also to press a thin document. When pressing, the link 6 can be held by the magnet 11, so the document holding cover 5 only needs to be rotated up and down with respect to the link 6, which simplifies the operation.

Since the document can be placed between the pair of links 6 and 6, a large size M4ii can be pressed onto it without having to remove it.

[Brief explanation of the drawing]

The drawings show an embodiment of the present invention, and FIG. 1 is an overall perspective view, and FIGS. 2, 3, and 4 are operation explanatory views. 5 is a document holding cover, 6 is a link, and 11 is a magnet.
