[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a film stocker in an automatic film developing machine, and more specifically, it may be appropriately washed with water during continuous processing such as development, bleaching, fixing, and stabilizing. The present invention relates to a film stocker arranged on the carry-out port side of a drying chamber, in which a strip-shaped photographic film subjected to so-called development processing is dried and carried out in a drying chamber as a final finishing step.

(Prior Art) Generally, a box-type film stocker in an automatic film developing machine is arranged on the film outlet side of a drying chamber, and a strip-shaped film with a film leader attached to the leading end of this film leader is the leading role. As a result, the film stockers naturally fall into the stocker from the ceiling opening, and the strip-shaped films are folded in a meandering shape and sequentially stocked.

(Problems to be solved by the invention) A film leader in which a strip-shaped film is continuously attached to the rear part is used as a guide when the strip-shaped film is being conveyed, and when the film is taken out from the stocker, Play a role.

When folding the above-mentioned strip-shaped film with the attached film leader into the film stocker, the film leader is at the bottom of the stocker, and the meandering film is located above the film leader. It is difficult for the operator to take out the film from the stocker with the film leader, and the film leader is caught, the film surface is damaged due to the contact between the leader and the film, and the entire area inside the film stocker is made effective. The stock property of the strip-shaped film used and the smooth transportability of the strip-shaped film could not be sufficiently satisfied by the free fall of this film.

The present invention solves the above problems inherent in the conventional stocker, separates the stock portion of the film reader and the strip film, effectively uses the entire film stocker, simplifies the removal of the strip film, and further The purpose is to provide a film stocker that can realize a smooth transition to a stock location.

(Means for Solving Problems) In order to achieve this object, the present invention has the following configuration. That is, the film stocker in the automatic film developing machine according to the present invention is a box-type film stocker arranged on the side of the film transport port of the drying chamber. A pair of guides / conveying means for the film leader extending from the drying chamber side toward the front side of the stocker is installed, and at least one of the side wall side means supports the lower surface of the conveying side portion with a support roller group and the upper surface. Is composed of an endless belt in which a weight roller group is arranged, and of these pair of guide / conveying means, only one side particularly extends to the film leader drop zone provided at the front end of the stocker and A film reader cradle is arranged at the bottom of the drop zone.

(Function) After the drying process is completed in the drying chamber, the film leader with multiple strips of film attached to the rear enters the film stocker, and both side edges of the film leader are used as the conveyor side of the endless belt and the strip-shaped guide, respectively. Or a pair of endless belts. The leader is placed on the belt and is gradually moved to the front part of the stocker along with the circulation movement toward the front part (anti-drying chamber side) of the film stocker on the endless belt conveyance side.

When the leader moves, and reaches the leader drop zone formed in the front part of the endless belt, the leader is supported by the belt guide or the endless belt only on one side edge of the leader, and the leader is a film leader. It falls naturally on the cradle. The strip-shaped film still sent out from the drying chamber is housed in the bottom of the stocker in a meandering manner, and the storage places of the film leader on the leader cradle and the strip-shaped film on the bottom of the stocker are divided. Further new film leaders that follow are similarly stacked on the leader pedestal, and the film portion is also stored in a meandering shape on the existing film at the bottom of the stocker.

(Effect of the Invention) The present invention is a film in which a belt for conveyance is arranged on at least one side wall portion near the inner wall surface of both left and right side walls constituting a stocker, and the belt is introduced into the film stocker, and a belt-like film is attached to the rear. By forcibly transporting the leader in the forward direction of the stocker and moving the leader surely to the forward part of the stocker, the entire interior of the stocker can be used effectively, and the film leader is placed on the leader cradle. However, by separating the storage portions of the film leader and the strip-shaped film from each other, it is possible to prevent the risk of damage to the film by the film leader.

The conveyor belt, which is erected toward the inner wall surface of the side wall of the film stocker so as to descend, is assisted by forced conveyance by a plurality of weight rollers arranged above the conveyor-side portion of the belt, and the lower surface is supported by the support roller group. The belt leader on the conveyor side always maintains a tension state without slack, and the film leader moves by being pressed by the conveyor belt surface, so even a single conveyor belt can achieve its intended purpose. It is possible to reduce the cost and weight of the product by this amount, and when a strip-shaped guide is used as a guide / conveying means of the film leader that supports the other side edge of the film leader, the other side of the film leader is used. The side edges are supported by the triangular edge pieces of the strip-shaped leader guide in a state close to line contact, so the leader guide and the fill It allowed reduce the contact resistance with the reader, thereby it is assumed the travel of the leader smooth. Further, of the film guide / conveying means erected along the pair of side walls constituting the stocker, only one means particularly extends to the leader drop zone area formed at the leading end of the film stocker, and conveys the conveying belt. Be sure to support the film leader that is out of the area,
When the trailing edge of the film leader is completely separated from the sandwiched state between the weight roller located at the end of the conveyor belt and the conveyor belt, the film leader can be surely dropped onto the leader cradle. It can be placed on the pedestal smoothly and systematically, and by forming the tip part of this leader guide in a plan view with a taper shape with a particularly wide tip, it can be partially supported from the conveyor belt. It is possible to secure the support of the film leader that is in the unstable state in which it is detached.
