Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a locking device for a filmset box in a film feeding device.

[Conventional technology]

Generally, when developing film using an automatic film processing machine, a leader is connected to the tip of the film pulled out from a film storage container such as a cartridge, and the leader is sent to the developing section first. Square holes are provided at equal intervals in the center in the feeding direction.

By the way, in conventional automatic film processing machines, only one leader can be set in the insertion box provided adjacent to the developing section, so each time the film is fed into the developing section together with the leader, the insertion box is It is necessary to open the upper cover and set the next reader and the film to which that reader is connected.

For this reason, when a large number of films are to be developed, the operator is forced to work with the automatic film developing machine all the time, resulting in extremely poor work efficiency.

In order to eliminate this inconvenience, the applicant connected the film set box 5 to the upper cover 3 of the insertion box 2 provided adjacent to the developing section 1, as shown in FIG. An automatic film developing machine having a film feeding device which sequentially feeds a large number of films F set inside the film into the developing section 1 one by one from an insertion box 2 with a leader L connected to the tip of the film in advance. (Refer to the specification of Utility Model Application No. 63-6277).

[The problem that the idea aims to solve]

Incidentally, in the above-mentioned automatic film developing machine having a film feeding device, the film set box 5 is provided on the upper cover 3 so as to be able to rise and fall freely around the pin 6, and when the film set box 5 is laid down, as shown by the chain line, , a large number of films with readers connected therein are set in a horizontal state, and when the film set box 5 is laid down, the tip of the film set box 5 and the upper cover 3
An opening is formed between the connecting port 8 and the connecting port 8 formed in the connecting port 8 .

Therefore, if the film set box 5 is accidentally tipped over when the film set box 5 is raised and the film F inside is fed into the developing section 1, there is a risk that the film F will be exposed.

The problem with this invention is to create a locking device for the filmset box that can reliably prevent the filmset box from being accidentally knocked over during the developing process when the films in the film set box are fed into the insertion box. The goal is to provide the following.

[Means to solve the problem]

In order to solve the above problems, in this invention, an engaging pawl having a hook portion at the tip is attached to the tip opening of the filmset box, which is connected to the upper cover of the insertion box so as to be able to rise and fall, and the upper cover A guide plate provided inwardly has an insertion hole for the engagement claw, and an engagement plate slidably provided along the inner surface of the guide plate has an insertion hole for the engagement claw inserted in the insertion hole. An engagement hole capable of engaging with the hook portion of the plate and a lock hole are provided, and the slide operation portion of the engagement plate is provided so as to be movable along a guide hole formed in the upper cover, and the engagement hole engages with the slide operation portion of the engagement plate. A spring is provided on the back of the engagement plate to deflect the lock plate in a direction in which it engages with the hook of the mating pawl, and the lock pawl, which is moved by a solenoid, is attached to the back of the engagement plate. A structure was adopted in which the lock can be freely engaged and detached from the lock hole.

[Effect]
