Abstract

PURPOSE:To obtain a carrier sheet free of deviation of an inserted article by providing a separable sheet which has enough friction or fine adhesive strength to prevent an inserted film, sheet, or form from deviating. CONSTITUTION:A sheet 3 for base paper is placed on an elastic sheet 2, and a sheet 1 for covering is put thereupon to form the carrier sheet. An inserted form, sheet, document, or original, etc., is placed on the elastic sheet 2, and the sheet 1 for covering covers the sheet 2 to set the carrier sheet on automatic equipment, e.g. facsimile equipment. The inserted body neither deviates nor moves and equipment operation is carried out smoothly. Thus, the elastic sheet 2 itself is uasble as base paper and the sheet 3 for base paper is unnecessary in this case.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a carrier sheet into which paper is inserted and held or protected. The carrier sheet into which manuscripts, original papers, documents, picture sheets, leaflets, pamphlets, photographs, printed matter and other similar articles are inserted usually consists of a receiving sheet and a backing sheet, with one end of both sheets, e.g. After the upper end is glued or stapled by an appropriate means, the covering sheet is turned over and the inserted sheet is inserted. Alternatively, the upper ends and side ends of both sheets may be adhered or stapled by appropriate means, and the inserted sheet may be inserted through the gap between the open ends. However, if the surfaces of the covering sheet and the mount sheet are both smooth, non-frictional, or non-adhesive, the inserted item is likely to shift or escape.

Office automation equipment, copiers, fax machines (
facsimile) and similar equipment for copying and (
Or) When transferring originals, they are usually inserted into a carrier sheet to protect their surfaces, and then hung on the device in this state.

In this case, the original may slip or move during feeding, which can be a problem. Furthermore, if the original is inserted incorrectly, only the transparent covering sheet of the carrier sheet may slide up, creating wrinkles. The wrinkles may get caught in the roll from the sheet inlet of the equipment, causing damage to the equipment. In the prior art, in order to prevent such troubles, an adhesive substance was applied or attached to one part or the edge of the mount sheet to prevent the base paper or manuscript (inserted sheet) from shifting, but it was difficult to use the mount sheet many times. After that, the adhesive substance is consumed and cannot prevent slippage. Alternatively, even if an attempt is made to prevent the base paper from shifting by inserting a hard plastic film or sheet between the receiving sheet and the base paper or between the base paper and the backing sheet, the base paper may move during feeding, and in some cases may damage the base paper.

Therefore, an object of the present invention is to provide a carrier sheet that prevents the above-mentioned inserted items from shifting. This objective is achieved by providing a peelable sheet, preferably an elastic plastic sheet, with abrasive or slightly adhesive properties.

The elastic plastic sheet preferably used in the present invention is, for example, a polyester elastomer product available from Hytrel Division of Toyo Products Co., Ltd. The product is a resilient, soft, abrasive or slightly adhesive peelable sheet that is transparent or translucent, but may optionally be colored or opaque. This elastic sheet is placed on a mount sheet, and a test sheet is placed on top of this to obtain a carrier sheet (see FIG. 1). The paper or sheet, document, manuscript, etc. to be inserted is placed on an elastic plastic sheet, covered with a covering sheet, and placed in an automation device, such as a fax machine. The device can be operated comfortably and smoothly without the inserted object shifting or moving. It is also possible to use this elastic plastic sheet itself as a mount, and in this case, the mount sheet becomes unnecessary (see FIG. 2). When the elastic plastic sheet is placed between the test sheet and the mount sheet, it can be easily inserted and removed, but one end of the elastic plastic sheet, e.g. the upper end, is adhered to one end, e.g. It is convenient to keep it or bind it. When using a mount sheet (Fig. 1), it is convenient to glue or bind the covering sheet, elastic plastic sheet, and mount sheet by appropriate means at one end, for example, at the top. It is. Depending on the purpose of use,
It is also possible to form a bag-shaped carrier sheet by binding not only the top edge but also the side edges or both sides.

When using the carrier sheet of the invention for office automation equipment, it is advantageous to impart flexibility to the entire carrier sheet.

The covering sheet is usually transparent, but may be made translucent, opaque, or colored depending on the purpose of use. The mount sheet is usually opaque or colored (for example, white), but may be transparent or colorless, and can be changed as appropriate depending on the purpose of use.

Although the elastic plastic sheet is usually a single item, it may also be a composite sheet obtained by combining an elastic plastic sheet on one side of a soft, semi-hard, or hard glass sheet (see Figure 3), or a soft, semi-hard, or hard glass sheet. It may also be a friction sheet obtained by surface-treating one side of a semi-rigid or hard plastic sheet to impart friction properties to the surface.

A carrier sheet (FIG. 1) was obtained by overlapping the sheets (0 cm, horizontal direction Oα) and binding the upper end pieces. This product is suitable for use in fax machines.

EXAMPLE A carrier sheet (Fig. 2) was obtained by stacking a transparent covering plastic sheet and the above-mentioned Hytrel and binding the upper end pieces.

Example 3 A semi-rigid plastic sheet (thickness 0./Ryu) was surface-treated by a sandblasting method to obtain a frictional plastic sheet. Note that frictional plastics can also be obtained by surface treatment using a matting agent coating method instead of the sandblasting method. This abrasive plastic sheet was used as a mount, and a transparent plastic sheet was placed on top of it, and the upper end pieces were glued together to form a sheet with a length of 30 cm.

This product is suitable for use in copying equipment.
