DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a developing film which is developed by a leader transport type automatic film developing apparatus.

[0002]

2. Description of the Related Art In general, when a photographed film wound in a patrone is developed by a leader transport type film developing device, a tongue portion at the leading end of the film is pulled out from the patrone and cut. After a leader is connected to the end of the film, the film is transported to the film developing section with the leader first.

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.

In general, the connection between the leader and the film is performed by attaching a splice tape. However, it takes time and effort to attach the splice tape and remove the film after the development process. Since it is necessary to accurately connect to the position, there is a disadvantage that a special work table for splice is required. Also,
Splice tapes cannot be reused, so there is a problem in economy.

In order to solve the above problems, the present applicant has already proposed a connecting structure between a reader and a film shown in FIG. 6 (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 hole h for feeding, 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]

By the way, when the film is transported to the film developing section by being pulled by the leader L, a pulling force acts on the engaging hole 4 of the film F. Therefore, when the strength of the film F is weak, The film F may be torn from the engagement hole 4.

In particular, in the case of a 135 film wound around a patrone, since the strength of the 135 film is low, the 135 film is often torn from the engagement hole 4 when the leader L pulls the film, and the 135 film is stretched along the film transport path of the film developing section. Is very poor in ensuring the reliable transfer of

Here, if the film is torn from the engagement hole during the transfer of the film, the film stops, and it is necessary to take out the film with the automatic film developing apparatus stopped. Since it is necessary to take out the film, it takes a lot of trouble to take out the film, which greatly reduces the operation rate of the automatic film developing apparatus.

An object of the present invention is to make it possible to surely transport a 135 film in a patrone along a film transport path of a film developing section by a film hooking type reader.

[0012]

In order to solve the above-mentioned problems, according to the present invention, a label having an adhesive layer on one side is attached to the leading end of a 135 film drawn from a patrone, and the label and the 135 A configuration is employed in which each of the films is provided with an engagement hole capable of engaging with a protruding piece provided on a leader for film towing.

Here, the engagement hole may be formed after the label is attached, or may be formed in advance before the label is attached, and the engagement hole formed in the 135 film and the engagement hole provided in the label may be formed. Attach the label so that matches.

The 135 film wound in the patrone has a curl, and when pulled out of the patrone,
It often curls in one direction. 13 with curl
If the film 5 is connected to a film hook-type reader and transported to the film developing section, the film may be clogged in the film transport path.

Therefore, in the case of a curled 135 film, it is preferable to remove the curl. In order to remove the curl, in the present invention, the leading end of the 135 film drawn from the cartridge is curled in the opposite direction, and a label is attached to the concave surface side.

If a heat-adhesive label is used as the label, the curl of the 135 film can be removed when the label is heat-adhered.

At the time of applying the label, a concave curved surface is provided on the upper surface of the film stand for receiving the leading end of the 135 film,
Affixing the label along with the 135 film tip along the concave curved surface enables the 135
The curl of the film can be removed.

Further, 135 is formed by the concave curved surface of the film base.
The curl of the 135 film can be more easily removed by using a hammering tool having a built-in heater in the pressure pad for holding the film and having a convex surface along the concave surface on the lower surface of the pressure pad. .
