BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film splicing apparatus for connecting a film to a reader used when developing a film.

[0002]

2. Description of the Related Art Generally, when a film is developed by an automatic film developing apparatus of a leader transport type, the film is connected to a flexible leader, and the film is transported to a film developing section in advance of the leader. ing.

Here, the leader is made of a synthetic resin sheet and has flexibility, and feed holes that can be engaged with sprockets provided in the film developing section are provided at equal intervals.

[0004] In general, the connection between the leader and the film is made by attaching a splice tape.
It takes time and effort to attach the splice tape and remove it after the development processing, and it is necessary to connect the film to the leader at a predetermined position with high accuracy. Therefore, there is a disadvantage that a special work table for splicing is required. Also, the splice tape cannot be reused, and therefore has a problem in economy.

In order to solve the above problems, the present applicant has already proposed a connecting structure between a leader and a film shown in FIG. 9 (Japanese Patent Application No. 7-230253).

In the connection structure, a first insertion hole 1 and a second insertion hole 2 are formed in a leader L having a feed hole a, and a protruding piece 3 crossing the first insertion hole 1 in the reader transfer direction is provided. The leading end of the projecting piece 3 is integrated with the leader L, the rear end is supported by the peripheral edge of the first insertion hole 1, and the leading end of the film F is moved from the second insertion hole 2 to the first insertion hole 1. And the projecting piece 3 is engaged with an engaging hole 4 provided at the front end of the film F.

The connection structure between the reader and the film is characterized in that the film can be easily and reliably connected to the reader, and that the film can be connected to a predetermined position of the reader.

[0008]

SUMMARY OF THE INVENTION An object of the present invention is to provide a film splicing apparatus which can automatically connect a film to a reader in the above-described structure for connecting a reader and a film.

[0009]

In order to solve the above-mentioned problems, according to the present invention, a leading end of a film is inserted from a second insertion hole provided in a reader into a first insertion hole close to the second insertion hole. In a film splicing device in which the projecting piece crossing the first insertion hole is elastically deformed by the film and the film is pulled back and the projecting piece is engaged with the engaging hole at the leading end of the film, the leader is placed on the film. An opening for inserting a long film in the front-rear direction is formed in the table, and a support portion for a film cartridge wound with a film is provided on the opening. A fixed guide is provided below the table, and a width of the table is set on the fixed guide. A movable guide that forms a film reversing passage whose entrance and exit face the opening between the fixed guide at a position facing the fixed guide, A feed roller that is moved in the width direction of the table together with the movable guide at the entrance of the film reversing path, and a pressing roller that sandwiches the film with the feed roller are provided, and the film pulled out from the film cartridge on the support portion. Is provided from the second insertion hole of the reader placed on the table to the entrance of the film reversing passage.

Here, as the retraction means, an arc-shaped plate is attached to the tip of a swing arm that swings from below the table toward the table, and the tip of the arc-shaped plate can be engaged with the engagement hole of the film. The swing arm is pivoted upward to engage the hook of the arcuate plate with the engaging hole of the film to draw the film into the entrance of the film reversing passage. be able to.
