DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film storage sheet guide and a photographic processing apparatus having the same, and more particularly, to an improved technique of a film storage sheet guide which can be mounted on a photographic processing apparatus and is not easily affected by static electricity. The present invention relates to a photographic processing apparatus having the same.

[0002]

2. Description of the Related Art A photographic film that has been developed and printed (hereinafter simply referred to as "film") is cut every four or six frames and inserted and stored in a film storage sheet. This film storage sheet is cut when a film of one order unit is stored, then folded at predetermined steps, stored in a print bag together with the printed photographic print, and returned to the customer. Here, one order unit means a film unit of one photographic film housed in one patrone or cartridge.

[0003] In this case, folding of the film storage sheet storing the film of one order unit is automatically performed in the film storage sheet handling portion of the photographic processing apparatus, and the folded film storage sheet is discharged to a tray or the like. It has become. The film storage sheet has an ID printed or affixed to a predetermined portion of the film.
The code of the number or bar code is compared with the code of the photographic print that has been finished separately, and if it is confirmed that they match, the print is stored in a print bag and returned to the customer.

[0004]

However, since the film accommodating sheet is made of a thin resin, it may be charged with static electricity in the course of being conveyed. If the film accommodating sheet is conveyed by a driving force, it is forcibly moved. Has little effect on the process due to static electricity, and does not hinder transport due to static electricity.However, if the film storage sheet moves in a place where driving force does not act on the transport of the film storage sheet, the static electricity may hinder transport. May be harmful. That is, the action of static electricity causes the film accommodating sheet to adhere to peripheral device parts and bend or delay conveyance, so-called uneven feeding occurs, which sometimes hinders the conveyance process.
In particular, in the case of a sheet that stores four frames of film, the width can be narrow, but the sheet length for one order is long,
Feed unevenness is likely to occur on the way. If feed unevenness occurs,
In each case, since the operator is troubled, the work efficiency is reduced, and it has been desired to develop a photographic processing apparatus which does not cause such a problem.

Accordingly, an object of the present invention is to solve the above-mentioned problems of the prior art, and in particular, to provide a film storage sheet guide and a film storage sheet guide which are less likely to adhere to a film storage sheet conveyance portion in a place where no driving force is applied. Provided is a photographic processing apparatus having the same.

[0006]

The above object is achieved by the invention described in each claim. That is, the characteristic configuration of the film storage sheet guide according to the present invention is a film storage sheet guide that can be mounted on a photographic processing apparatus.
A first contact means is provided on a guide guide surface in contact with the film storage sheet, the first contact means being in contact with a plurality of points of the film storage sheet in a dotted or linear manner. With this configuration, even when the film storage sheet being conveyed is charged with static electricity, the film storage sheet guide only comes into contact with a plurality of points of the film storage sheet in a dotted or linear manner. Therefore, it is possible to prevent the conveyance from being delayed due to the electrostatic charge. Therefore, when transporting the film storage sheet at a transport location where the driving force does not act, since transport unevenness does not occur, it is possible to reliably prevent the occurrence of trouble due to transport unevenness as occurs in the related art,
Work efficiency can be maintained high. As a result, it was possible to provide a film storage sheet guide that is less likely to adhere to the film storage sheet transport portion due to static electricity, particularly at locations where no driving force acts.

Here, the term "point-like or linear contact" is intended to exclude a case where the contact is made in a planar manner over a certain range, such as a close contact when static electricity is generated, Strictly speaking, it is used as a concept meaning a case where the contact is substantially a point or a line even if the contact is a planar contact.

[0008] The first abutting means comprises a plurality of thin plate-like convex pieces arranged at substantially equal intervals in the width direction of the film storage sheet. It is preferable that the interval between the two is smaller than the width of the film storage sheet. Usually, 4 or 6 frames of the developed film are inserted and stored in the film storage sheet, and the distance between the end portions of the convex pieces is appropriately adjusted according to the width of the film storage sheet. By making it narrower, it is possible to reliably avoid surface contact with the film storage sheet guide, and it is possible to prevent conveyance from being delayed due to electrostatic charging.

Further, the characteristic configuration of the photographic processing apparatus according to the present invention includes a transport section for transporting a film storage sheet for storing a film which has been subjected to the printing process to a winding section, and an order of one order for the transported film storage sheet. A winding unit that winds each time, an opening that allows the film storage sheet to be discharged outside the housing that constitutes the outer shell before the winding unit winds the film storage sheet, and a charging unit that is loaded into the opening. Item 1 or 2 is that the film storage sheet guide is provided.

[0010] With this configuration, even if the conveyed film storage sheet is charged with static electricity, the conveyed film storage sheet may come into contact with no driving force. Since the film storage sheet guide only abuts on a plurality of points of the film storage sheet in a dot-like or linear manner, there is no possibility that the conveyance is delayed due to the electrostatic charge. Therefore, when transporting the film storage sheet at a transport location where the driving force does not act, transport unevenness does not occur, so that it is possible to reliably prevent the occurrence of trouble due to transport unevenness as occurs in the related art, and to maintain high operation efficiency. . As a result, it has been possible to provide a photographic processing apparatus in which static electricity is less likely to adhere to the film storage sheet conveying portion particularly at a location where a driving force does not act.

Further, there is provided a second abutting means which abuts on a point or a line which can avoid a planar contact with a flat portion of the housing when the film storage sheet is discharged out of the opening. Is preferred. In this case, even if the transported film storage sheet is charged with static electricity, the film storage sheet guide that may be brought into contact with the transported film storage sheet in a state where no driving force is applied. In addition to the guide, the housing only comes into contact with a plurality of points of the film storage sheet in a dot-like or linear manner, so that there is no delay in transport due to electrostatic charging. Therefore, when transporting the film storage sheet at a transport location where the driving force does not act, since transport unevenness does not occur, it is possible to more reliably prevent the occurrence of trouble due to transport unevenness as occurs in the conventional technology,
Work efficiency can be maintained high.

The second abutting means is formed at a lower position of the housing substantially corresponding to the film storage sheet guide, and includes a plurality of thin plate-like convex pieces arranged at substantially equal intervals. In addition, it is preferable that the interval between the extreme ends of the convex pieces is smaller than the width of the film storage sheet. With such a configuration, the interval between the end portions of the convex pieces is appropriately formed to be narrower than the width of the film storage sheet in accordance with the width of the film storage sheet, so that the gap between the film storage sheet guide and the film storage sheet guide can be reliably achieved. Surface contact can be avoided, and it is convenient that conveyance is not delayed due to electrostatic charging.

[0013] It is preferable that the upper surface of the convex piece is formed to be inclined, and the inclination angle is an acute angle. With this configuration, when the descending film accommodating sheet comes into contact with the upper surface of the convex piece, it can be smoothly moved down beyond the upper surface of the convex piece without any delay. In this case, the inclination angle is preferably several degrees to less than 90 degrees, and more preferably 5 to 45 degrees.

[0014]

Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a structure of a film storage sheet handling portion 1 of a photographic processing apparatus A according to the present embodiment. The film storage sheet handling section 1 includes a transport section 3 for holding and transporting a negative sheet 2 which is a type of film storage sheet, and a transport section 3 for transporting the negative sheet 2 to the negative sheet 2.
And a winding unit 4 for winding the wound negative sheet 2 at a perforated level, and a discharging unit (not shown) for discharging the wound negative sheet 2. Here, the negative sheet 2 is structured such that strips of four or six frames, each of which has been developed and divided into several stages, are sequentially arranged in the longitudinal direction of the negative sheet 2 and inserted and stored.

The transport section 3 includes drive rollers 5 (only one roller is shown and others are not shown) for nipping and transporting the negative sheet 2 on both sides in the transport direction (perpendicular to the plane of FIG. 1). And a belt 6 is stretched between the drive roller groups 5. Since the drive roller groups 5 on both the left and right sides have the same shape, respectively, FIG.
Then only one is shown. A driven roller 7 is disposed below the driving roller 5, and the negative sheet 2 is nipped and conveyed between the driving roller 5 and the driven roller 7. However, the negative sheet 2 may be pinched and conveyed between the driving roller group and the driven roller group without using the belt that is wound around the driving roller group 5, and the belt may also be wound around the driven roller group. Negative sheet 2
Can be adopted.

A retracting plate 8 is supported below the driven roller 7 so as to be rotatable around a support shaft 8a. This escape plate 8
Normally retracts below the transport path of the negative sheet 2 as shown by the two-dot chain line in FIG.
Is transported to the take-up section 4 and is rotated to the position facing the transport path as shown by the solid line in FIG. This rotation is performed by a motor or the like arranged outside the figure. At this time, the rotation can be automatically performed by detecting that the negative sheet 2 has been conveyed.

The take-up section 4 includes a pair of take-up rods 4a, 4a constituting a take-up member for taking up the negative sheet 2 step by step.
It has. Each of the winding rods 4a has a rectangular cross section, and has a prismatic shape having a sufficient length for winding the negative sheet 2. And winding rod 4
a and 4a are arranged at positions slightly eccentric from the winding center, and draw a circular locus indicated by a two-dot chain line in FIG. It is designed to rotate. And winding rod 4
When the negative sheet 2 is wound, a pair of holding plates 9, which hold the negative sheet 2 in response to the clockwise or counterclockwise rotation of the winding rods 4 a, 4 a above the negative sheet 2.
9 are provided. The holding plate 9 is rotatable around an axis 9a, and is not shown in the drawings.
Is biased to the position shown in FIG.

After the negative sheet 2 is once discharged from the opening 10 of the housing 1a constituting the outer shell of the photographic processing apparatus A, the negative sheet 2 advances in the reverse direction by the rotation of the winding section 4, as described later. Then, it is wound by the winding rods 4a, 4a. When the negative sheet 2 starts to be wound by the winding rods 4a, 4a, the pressing plate 9 presses the negative sheet 2 so that the negative sheet 2 cannot be unwound. In addition, the winding rod 4a,
Various materials such as metal and resin can be used for 4a, but it is preferable that the surface is coated with a material having a high coefficient of friction such as rubber, because slippage can be prevented when winding up the negative sheet 2.

Further, an opening 10 for temporarily discharging the negative sheet 2 is formed in a portion of the housing 1a corresponding to the traveling direction in which the negative sheet 2 is conveyed. 2 can wait outside the apparatus. That is, before the negative sheet 2 is wound up by the winding rods 4a of the winding section 4, the negative sheet 2 is temporarily ejected outside the apparatus in order to turn the negative sheet 2 back and forth. This reversal is performed because the ID code or bar code for specifying the customer is printed or affixed to the film inserted and stored in the negative sheet 2 so that the ID code or the like is wound up so that the operator can directly see it. To do.

When the negative sheet 2 is temporarily discharged from the opening 10, the negative sheet 2 is held at the upper and lower positions of the opening 10 by the film storage sheet guides 11 and 12.
(Hereinafter, referred to as a “guide guide”) in a predetermined direction. The negative sheet 2 first includes the upper guide 11
And is guided downward, but the upper guide 1
As shown in FIG. 3, a plurality of thin plate-shaped convex pieces 11 are provided.
c, the negative sheet 2 abuts on the convex piece 11c in a linear or dot-like manner. Therefore, even if the negative sheet 2 is charged with static electricity, the negative sheet 2 There is no possibility that the guide guide 11 comes into contact with and adheres to the guide guide 11 in a planar manner and hinders the subsequent progress. That is, the upper guide guide 11 is contacted with the advancing negative sheet 2 to guide the negative sheet 2 downward. It is composed of two sets of convex members 11a having a U-shaped cross section and having a pair of convex pieces 11c, 11c, which are joined to each of the bifurcated portions. It is installed so as to be inclined as a whole, is inserted into the inside of the photographic processing apparatus A through the opening 10, and is mounted using a conventional fixing means.

The main body 11b and the two sets of convex members 11a are made of a metal such as a thin steel plate or an aluminum plate, are formed by press working or the like, and are joined together by welding or the like to be integrated. However, the joining of both may be performed using an adhesive. Further, the main body 11b and the two sets of convex members 11a may be integrally formed. In other words, both edges of the forked tip portion of the main body 11b may be formed by bending in one direction. Here, the convex member 11a and the convex piece 11c correspond to a first contact unit.

The arrangement of the convex members 11a may be such that the interval between the endmost convex pieces 11c, 11c is smaller than the width of the negative sheet 2 for 4 frames or 6 frames. Various shapes can be considered as the shape of the convex member 11a, but it is essential that the negative sheet 2 to be sent does not exactly come into surface contact with the flat portion of the main body 11b by the action of static electricity.
In particular, in the case of the upper guide 11 of the present embodiment, four convex pieces 11c of two sets of convex members 11a having a U-shaped cross section are implanted in the main body 11b at substantially equal intervals. The negative sheet 2 is configured so that the surface of the negative sheet 2 abuts substantially linearly or at a point at four places of the thin plate-like convex pieces 11c, so that the negative sheet 2 itself contacts the convex member 11a. Not only does it not adhere, but also the left and right ends of the negative sheet 2 do not make surface contact with the main body 11b, and the negative sheet 2 is guided smoothly and reliably downward.

Next, the negative sheet 2 is a lower guide 1
2 and descends downward, while contacting with the lower guide guide 12 at the bent convex portion. In this case, too, the contact is only at most linear. Even if the negative sheet 2 is charged with static electricity, there is no hindrance to the subsequent progress. Furthermore, when the negative sheet 2 descends downward, since the plurality of thin plate-shaped convex pieces 1b are also formed on the housing 1a of the photographic processing apparatus A, the negative sheet 2 is similarly charged with static electricity. Even if the negative sheet 2 is the upper guide 1
It does not adhere to 1 and hinder subsequent progress. Here, the convex piece 1b corresponds to a second contact means.

The convex piece 1b is also connected to the upper guide 1
The two sets of the convex member portions 11a are formed so as to be implanted at four positions of the housing 1a at lower positions substantially corresponding to the four convex pieces 11c. Therefore, the convex piece 1
The interval of b is two sets of the convex members 1 of the upper guide 11.
Although it may be substantially the same as the four convex pieces 11c at 1a, the length is preferably formed to be longer than the two sets of convex members 11a of the upper guide 11 and the negative sheet 2 is inadvertently formed in the housing 1a. It is preferably formed to such an extent that it does not come into contact with the flat portion of the substrate and is not attached by the action of static electricity. Here, the convex piece 1b constitutes a separating means for preventing the negative sheet 2 from contacting and adhering to the flat portion of the housing 1a.

The convex piece 1b may be integrally formed by being raised from the housing 1a by press molding or the like,
It may be separate and joined to the housing 1a by welding or an adhesive. The edge 1c on the upper surface side of the convex piece 1b is finished in an inclined shape, and the tip of the descending negative sheet 2 is smoothly and reliably formed in the housing 1a.
In this case, the negative sheet 2 descends in a direction in which the negative sheet 2 is further separated from the housing 1a. The inclination angle の of the edge 1c on the upper surface side of the convex piece 1b is preferably an acute angle from several degrees to less than 90 °. The projecting height of the convex piece 1b may be at least about 10 mm in order to separate the negative sheet 2 from the housing 1a. A cover that covers the entire guide may be attached.

[Another Embodiment] (1) Housing 1a
5 may be used as the shape of the convex piece 1b. That is, the convex pieces 1b 'have a substantially triangular shape in a side view, and are formed in large numbers with an acute upper surface rising angle に on the surface of the housing 1a. Since the negative sheet 2 only comes into contact with or comes into contact with the descending negative sheet 2 in a point-like or linear manner, the negative sheet 2 is
Can be reliably prevented from being in contact with and adhering to the flat surface portion.
Also in this case, these convex pieces 1b 'may be integrally formed by press working, or may be joined to the surface of the housing 1a as a separate member.

(2) As a modified example of the convex piece 1b formed on the housing 1a, as shown in FIG. 6, the surface of the housing 1a on which the negative sheet 2 descends is a corrugated plate-like surface 1.
It may be a '. Even with such a shape, the same operation and effect as the above-described embodiment can be exhibited. It is preferable that the upper surface of the corrugated plate-like surface 1a 'has an inclined shape rising at an acute angle, as in the above-described embodiment. The corrugated plate-like surface 1a 'may be formed over the entire surface of the housing 1a, or may be formed only at a position where the negative sheet 2 descends. In this case, the corrugated plate-like surface 1a 'of the housing 1a corresponds to the second contact means.

(3) As the photographic film, either a negative film or a positive film can be used.

(4) The cross-sectional shape of the film sheet winding rod is not particularly limited, and may be not only the square rod shape shown in the above embodiment but also a round rod shape or another shape.

(5) The guide guide and the convex piece are preferably made of a conductive metal, but other materials may be used. In the case of a resin, the surface may be coated with a conductive paint. preferable.
