様のトラブルが発生し７ている。On the other hand, many copying machines use transparent or translucent films as copy paper for purposes such as overhead projectors, but the optical method described above is not suitable for these films. There was a stalemate that it did not work effectively. In other words, when an optical method is used in a copying machine that uses a conventional transparent or translucent film, light passes through the film and becomes undetectable, resulting in paper jams due to poor paper feeding timing. There was a problem in which the copying machine did not stop quickly in response to a paper jam. In order to solve this problem,
There are some transparent and translucent films with white bands on the market, but even when these commercially available films are used, the optical detection method does not always work effectively and similar problems occur. There are 7.

ムを提供することにある。SUMMARY OF THE INVENTION Therefore, an object of the present invention is to eliminate the above-mentioned drawbacks of the prior art, and to provide excellent running characteristics when used in a copying machine having an optical detection method, and to eliminate the occurrence of paper stickiness. The object of the present invention is to provide an electrophotographic film that can be easily detected and easily removed.

る東予写真用フィルムが提供さね、る。As a result of stacking ωl frames to achieve the above object, the present inventor discovered that in order for the optical detection method to operate effectively, an opaque area for detection that has an opacity above a certain value is required for the optical detection method to work effectively. I found out that there should be. Thus,
According to the present invention, there is provided a Toyo photographic film in which a coating layer is provided on a part of a transparent or translucent film, and the opacity of the coated part is 60 or more.

ルムを簡単に除去することがで六る。When copying operations are carried out using the photocopy film of the present invention, the presence of a coating layer with an opacity of 6 degrees or more ensures that the optical detection system operates reliably, thereby ensuring that the paper feed timing is adjusted to a predetermined time. It also ensures that the occurrence of a paper jam is detected and the jammed film can be easily removed.

Liimi P1 is manufactured by applying a coating material to a portion of a transparent or translucent film made of a polymer compound such as polyethylene or polyzolopyrene. The type of coating material is not particularly limited, and it must be durable and have excellent adhesion to the film used, and can provide an opacity of 60 inches or more without making the coating film too thick. Any paint or ink can be used as the coating material, if any. In addition, the opacity used in this specification, JIS P-8138
The measurements were taken according to the test method for measuring the opacity of paper.

For example, as shown in FIGS. 1 and 4, a coating layer 2 having an opacity of 60% or more is provided along one side of a transparent or translucent film 1. Alternatively, the coating layer 2 may be provided as shown in FIG. 2 or FIG. 3. Next, embodiments of the present invention will be shown.
