DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film connector used for connecting a photographed film to a reader.

[0002]

2. Description of the Related Art In general, when a photographed film is processed by an automatic film developing machine, the film is connected to a reader, and the reader is moved forward to transport the film to a developing section of the automatic film developing machine. I have.

In connecting a film to a leader, conventionally, as shown in FIG. 7, the leading end of a film F drawn from a patrone P is cut at a right angle to a side edge, and the leading end is connected to the edge of the leader L. They are connected by butting and attaching a splice tape piece T.

Incidentally, the film F has a base surface and an emulsion surface, and the base surface has a weaker adhesive force than the emulsion surface. Therefore, a splice tape piece T is usually attached to the emulsion surface.

[0005]

Since the base surface and the emulsion surface of the film F have different colors, the emulsion surface can be identified by the color. However, if the operator has little experience, a splice tape piece T is attached to the base surface. Was often affixed.

Here, if the splice tape piece T is incorrectly attached, the film F may come off from the reader L during the development processing of the film F, and it is extremely difficult to remove the film F. There is.

Therefore, as shown in FIG. 8, if the inclined edge C is provided at the front end of the film F in advance, the base surface and the emulsion surface of the film F can be determined from the inclination direction of the inclined edge C. By attaching the film F to the leader L such that the inclination direction of the inclined edge C is always constant, the splice tape piece T can be securely attached to the emulsion surface of the film F, which is caused by an incorrect attachment. Troubles can be prevented from occurring.

If the inclined edge C is provided at the leading end of the film F, when the film is loaded into a camera having a film auto-loading function, the film F is guided with respect to a guide for guiding the film F between the film feed rollers. There is also an advantage that the tip can be easily inserted and the film can be easily loaded.

By the way, in the case of the film F having the inclined edge C, the leader L and the film F cannot be relatively positioned, so that the film F can be accurately positioned so that the leader L and the film F are linearly arranged. The problem that connection is difficult arises.

An object of the present invention is to provide a film connector which can easily and firmly connect a film having an inclined edge at a tip thereof to a reader with high precision.

[0011]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a bulging portion on one side of a connecting piece, and the bulging portion has two bulging portions located in both ends of the connecting piece. One side is provided with a leader positioning section, and the other side is formed with a film positioning section. The film positioning section is inclined with respect to the leader positioning section at an inclination substantially equal to the inclination angle of the inclined edge of the leading end of the film. Thus, a configuration in which an adhesive layer was provided in the portion was adopted.

Here, the bulging portion may be formed by bending a positioning piece connected to a side edge of the connecting piece through a fold line on the connecting piece and fixing the positioning piece to the connecting piece.

[0013]

When connecting the film to the reader, the leader positioning portion of the connecting piece is brought into contact with one side of the trailing side in the transport direction of the reader being transported to the developing section, and the connecting piece is adhered to the reader. The inclined edge of the leading end of the film is brought into contact with the film positioning portion to adhere the film to the connecting piece.

In order to further increase the adhesive strength of the film, a film holding piece is connected to the side edge of the end of the connecting piece to which the film is bonded via a fold line, and the film holding piece is held by the film holding piece. An adhesive layer may be provided on the surface, and the film sandwiching piece may be bent toward the connecting piece and affixed on the film adhered to the connecting piece.

Further, in order to further increase the connecting force between the leader and the film connecting member, a leader holding piece is connected to the leader positioning side of the positioning piece via a fold line, and an adhesive layer is provided on the leader holding face of the leader holding piece. May be provided, and the leader holding piece may be bent toward the connecting piece and adhered to the leader adhered to the connecting piece.
