Description

[Detailed Description of the Invention] This invention relates to a document cover attachment device installed on a document tray of a copying machine.

When performing copying work, the original cover that covers the original placed on the original stand placed on the top of the copier is usually made of a flexible material such as rubber, or made of a hard material such as a synthetic resin board. Although it is well known that there are some
The present invention relates to an attachment device suitable for use in, but not limited to, the following:

The original to be placed on the copying machine's original table is not just a single sheet, but may also be a three-dimensional object, and even if it is a sheet, there may be multiple sheets, and it is necessary to properly align them with each other. There may be miscellaneous cases where it is necessary to place the

In such a case, in order for the copying machine operator to be able to place the original using both hands, the original cover must be in a raised position so that it is easy to cover the original again even when the hand is removed and after the original has been placed. It is desirable to retain it.

If the document is three-dimensional, it is necessary to configure the document cover so that it is horizontal and presses the entire document uniformly, regardless of its height.

Due to these various requirements, for this type of document cover, which should originally be extremely simple, for example, in the case of a cover made of flexible material, it is necessary to hold the cover in an upright position at the desired position. It is necessary to separately install a support frame, etc., or to use a snap-action spring mechanism in the case of a hard material manuscript cover, and the configuration of the manuscript cover including these additional mechanisms is difficult. Things always get complicated.

In this way, this proposal greatly simplifies the structure of this type of manuscript cover, which is unnecessarily complicated, even though it is for the convenience of use, and yet satisfies the requirements for a manuscript cover. The present invention provides a document cover for use in copying machines that can be used.

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a sectional view showing a manuscript cover according to the present invention,
A cover member 1 made of a hard material has a negative side 1 edge and both ends 2.
It is pivotally attached to the document stand or the top of the copier body at a certain point (only one pivot point is shown in the figure).
.

As shown in the figure, a mounting piece 3 is fixed to the upper surface of the original table, etc., and one end of a rod 4 is pivotally attached to this piece by a pin 5.

The other end of the rod 4 is pivotally connected to the falling portion of the cover member 1 by a pin 6.

Although only one of the pieces 3, rod 4, etc. is shown in the figure,
It is easy to understand that they are attached to both corners of one side edge of the normally rectangular cover member.

The structure of the cover member attachment portion, including the pieces fixed to the original table or the like, is clearer from FIG. 2.

That is, as shown in FIG. 2, the mounting piece 3 consists of a block part 33 having a hole 32 into which a pin 5 for pivotally mounting the rod 4 is loosely fitted, and a single-shaped part 31 extending from the block part 33. There is.

The hole 32 of this piece is overlapped with the hole at one end of the rod 4, and the cover member is rotatably attached to the piece near one corner 12 of the cover member 1 using the pin 5 and the nut 7. It is.

Other pieces (not shown) are connected to the cover member 1 through other rods in the vicinity of the corner opposite to the corner 12 of one of the rising lines 11 of the cover member 1. shall be installed.

As is clear from FIG. 1, the falling edge 11 of the cover member is in close contact with the above-mentioned cursor-shaped portion 31 when the cover member is in close contact with the original table or the like. The lower end of the falling edge, the falling edge body, and the cover are fitted into the recess formed by one side of the block portion of the piece, and when the cover member is rotated to the fully open position shown by the chain line A in the figure, the lower end of the falling edge, the falling edge body, and the cover are rotated. The top surface of the member is configured to engage each surface of the recess, that is, one side of the block portion of the mounting piece, and the bottom surface and rising portion of the L-shaped portion to maintain the fully open position shown in the figure. It is.

Since the original cover according to the present invention has the above-mentioned structure, it can be used when copying a single-sheet original, which is often used.

The right end of FIG. 1 can be rotated upward by an appropriate angle with one hand of the operator to place the original on the surface F, and the other hand can quickly replace the original one after another without removing the cover member.

In addition, when it is necessary to use both hands to place the original on the surface F, by rotating the cover member 1 to the position of the chain MA in FIG. The cover member can be easily maintained in the open position by the cooperative action of the recessed portion and the rising edge of the cover member.

Furthermore, in the case of copying a three-dimensional object, a thick book, etc., the cover member, which is supported by pins 5, 602 points via the rod 4, can Regardless of the thickness, the cover member 1 can always be maintained parallel to the plane F and a uniform suppressing effect can be applied to the object to be copied.

As explained above, the present invention not only achieves the same effect with an extremely simple structure without using a known spring or snap action, but also allows thick originals to be placed on it. This is a useful device that can always apply a uniform force without substantially changing the pressing force depending on the position on the surface F.

Claims (1)

[Scope of Claim for Utility Model Registration] A pair of mounting pieces 3 are attached to the document placement surface side at positions corresponding to both ends of one side edge of the cover member 1 arranged so as to cover the document placement surface F. When connecting the mounting piece 3 and the cover member 1 via the rod 4, one end of the rod 4 is pivotally connected to the mounting piece 3 with a pin 5, and the other end of the rod 4 is connected to the cover member 1. The cover member 1 is pivotally connected to one member 1 by a pin 6, and the cover member 1 and the rod body 4 are rotatable together with respect to the document placement centering on the pivoted part by the pin 5, and the pins 5 and 6 are rotatable as a unit. The cover member 1 is movable at least parallel to the document placement surface by pivoting both pivot points according to A document cover for a copying machine, which is provided with a recessed portion for holding the document in that position.
