Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a thin copy paper carrier for an electrophotographic copying machine.

Image transfer type electrophotographic copying machine, so-called P, P.

With C, copies can be made on plain paper without any special processing.

However, as the plain paper is transported through the machine by rollers, guide plates, etc., and undergoes transfer, separation, fixing, etc., thin or weak paper can easily bend or tear during the process. Conventionally, it is 70 to 100 because it causes clogging
Copying could only be done on paper that was relatively thick, about μ in size.

Therefore, it was not possible to make very thin copies on paper.

In view of the above points, it is an object of the present invention to provide a thin copy paper carrier that enables copying onto very thin paper and can be used repeatedly.

To explain an embodiment below, the thin copy paper carrier 1 of the present invention has a mount part 2 made of a flexible thin plate and a thin copy paper provided on one side thereof, that is, the tip end in the direction of inserting the copy paper into a copying machine. It consists of a holding section 3 for holding the leading edge of copy paper.

In the embodiment, the holding part 3 holds the tape-shaped thin plate 4 on the mount part 2.
At the same time, it is glued at the narrow adhesive part 5 at the tip thereof,
Both side parts 6, 6' are also fixed to the mount part.

Lift up the open end 4' of the tape-like thin plate 4 fixed to the mount section 2 in this way, insert a thin paper 7 to be used as copy paper between it and the mount section 2, and press it from the holding section 3 side. Insert it into the copier.

In order to fix the tape-like member as a holding part to the tip of the mount part 2, as shown in FIG. Alternatively, the back surface and the tip may be bonded together.

In this case, it is desirable that the tape-like member has such elasticity that the opening edges of the U-shaped cross section approach each other.

As the mount portion 2, a cardboard of about 300 μm or a flexible resin board such as Mylar (trademark) can be used.

Further, the tape-like thin plate 4 may be made of paper or the like.
A resin thin plate such as Mylar having a certain degree of elasticity is suitable.

In the embodiment shown in Fig. 1, the tape-like thin plate is fixed on three sides, but the point is that it is sufficient to clamp and fix the tip of the thin paper, and only the tip or both ends of the tape-like thin plate can be attached to the mount. It can also be implemented in a fixed manner.

Furthermore, holding portions may be provided on two sides of the thin copy paper carrier in consideration of its use in the vertical and horizontal directions.

If one end of the thin copy paper is sandwiched between the ends 4' of the holding part 3 of the thin copy paper carrier mentioned above and fed into the copying machine from this part, the thin copy paper will be transported inside the copying machine together with the mount part 2. Even when it passes through the feed rollers and guide plates, the flexibility and stiffness of the mount section 2 allows it to pass through without bending on the way, and it can be copied in the same way as with normal thick materials. be effective.

When copies were made on thin paper of approximately 30μ, 40μ, and 60μ using this product, the copies were made well and no paper jams occurred.
