Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photosensitive material conveying device, and more particularly to an automatic feeder for a photographic film.

[0002]

2. Description of the Related Art Photographic films taken by optical cameras are subjected to a chemical treatment in a photo lab, whereby a permanent image is formed on the film.

[0003]

By the way, in the prior art, when an exposed film is fed to a processing apparatus for performing a chemical treatment on a photographic film for each cartridge,
The operator had to manually set the patrone one by one at a predetermined position. Therefore, there is a problem that the processing efficiency is reduced and the operator's hand is troublesome.

To solve such a problem, an auto feeder for automatically setting a patrone in a processing apparatus has been devised. However, a problem that can be expected in setting the patrone in the processing apparatus is whether the processing apparatus can properly extract the film from the patrone. That is, the processing apparatus cannot grip the film to be processed unless the film of the regulated length has been drawn out from the patrone in advance. Also, even if a film of a regulated length is pulled out of the patrone, if the patrone is supplied to the processing device while tilted,
Similarly, the film cannot be gripped and cannot be processed.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to provide a photosensitive material transport apparatus capable of transporting a container containing a photosensitive material to a processing apparatus.

Then, a holder for holding the container containing the photosensitive material, a set position for holding the container containing the photosensitive material on the holder, and the container containing the photosensitive material are taken out of the holder. A moving means for moving the holding body between a take-out position and a moving position of the photosensitive material held by the holding body when the moving means moves the holding body to the take-out position. Taking out the container from the holding body and supplying it to the processing apparatus, the holding body is configured to hold the container in a state where the tip of the photosensitive material is pulled out, Taking Out means, from said holder, characterized in that is adapted to take out the container pulled out of the tip of the photosensitive material.

[0007]

According to the photosensitive material transport device of the present invention, the holder holds the container with the tip of the photosensitive material pulled out, and the take-out means moves the photosensitive material from the holder. The container is taken out with its tip pulled out, so if the container can be set in the processing device while maintaining such a state, the processing device can properly grasp the photosensitive material and thereby can execute the processing reliably. Becomes

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of a transport device (auto feeder) according to the present embodiment. FIG. 2 is a top view showing the patrone at the take-out position together with a part of the transport device. In FIG. 1, the transport device includes a transport unit 10 as a moving unit, an adapter 20 as a holder, and a patrone extruder 30 as a take-out unit. In FIG. 1, a processing device 40 for processing a photographic film stored in a patrone is disposed adjacent to the left side of the transport device.

The transport unit 10 includes two sprockets 11,
12 and an endless chain 13 engaged with the sprockets 11 and 12. The sprocket 11 is connected to a motor via a gear mechanism (not shown).

Around the chain 13, twelve adapters 20 are attached so as to move together with the chain 13. In FIG. 1, only the two adapters 20 on the left are shown in a sectional view. In FIG. 1, the five adapters 20 shown at the top are located at the set position, and the adapter 20 shown at the leftmost position is located at the take-out position. In the adapter 20,
A patrone Pt containing a film as a photosensitive material can be freely inserted. A sensor 50 that can determine the presence or absence of the cartridge Pt is arranged near one of the adapters 20 in the lower part of FIG. The configuration of the adapter 20 will be described later.

A patrone extruder 30 is provided in parallel with the chain 13. The cartridge extruding device 30 includes an actuator 31 and a rod (extruding member) 32 that can be extended by driving the actuator 31.

As shown in FIG. 2, an arm 32a is formed at the free end of the rod 32. The arm 32a has an inverted L-shape. When the rod 32 pushes out the patrone Pt, the left end face of the arm 32 in the drawing comes into contact with the side surface of the film F drawn from the patrone Pt. .

Next, a detailed configuration of the adapter 20 will be described. Since each of the twelve adapters 20 has the same shape, only one of them will be described. FIG.
FIG. 4 is an enlarged perspective view showing the adapter 20, and FIG. 4 is a view of the adapter 20 of FIG. In addition, in order to facilitate understanding, in FIG.
Is indicated by a two-dot chain line (virtual line). In FIG. 4, the cartridge Pt is shown in a state of being held by the adapter 20.

In FIG. 3, the adapter 20 has a substantially L-shaped box shape, and includes a main body 21 for storing a cartridge Pt and a film holding portion 22 for storing a film F drawn from the cartridge Pt. The widest surface (mounting surface) 20a of the adapter 20 is the chain 1
3 (FIG. 1). In addition, since the adapter 20 has neither a top surface nor a bottom surface, the cartridge Pt can be relatively moved upward and downward in FIG.

A notch 21a is formed at the upper end of one corner of the main body 21. When the patrone Pt once inserted into the adapter 20 is taken out for some reason, the patrone Pt exposed from the notch 21a is easily grasped by the operator with a finger. As shown in FIG. 4, a spring member 23 is provided inside the main body 21 to urge the cartridge Pt toward the film holding portion 22.

In FIG. 3, chamfers 22a and 22b are formed on the upper edge of the opposite side wall of the film holding portion 22. When the film F drawn from the patrone Pt is inserted into the film holding portion 22, , So as not to get caught on the upper edge of the side wall.

As shown in FIG. 4, the film holder 22 has a tapered shape. The inner dimensions of the film holder 22 are width A = 45 mm, left height B = 5 mm, and right height B in FIG. Height C = 2 mm. Such a shape has an effect of regulating the position of the leading end of the film F (FIG. 3) by the film holding portion 22.

FIG. 5 shows that the adapter 20 has a small diameter cartridge used for a simple camera that can be recycled.
FIG. 5 is a view similar to FIG. FIG.
As is apparent from the figure, the patrone pt is pressed toward the film holding portion 22 by the extended spring member 23, and therefore, regardless of the diameter of the patrone, the adapter 20 can hold the patrone and draw out the film F that has been pulled out. Length can be regulated.

Next, the operation of the transfer device according to the present embodiment will be described. In the initial state, the rod 32
Is in a state of being pulled back toward the actuator 31 without being in an extended state as shown in FIG. First, when the operator turns on a switch (not shown), power is transmitted to the sprocket 11 in FIG. 1 via a motor (not shown). Thereby, the chain 13 starts moving in the direction of the arrow in the figure.

Here, the operator pulls out the film F from the patrone Pt by a predetermined length (43 to 45 mm: 2 mm is a margin) in advance. Otherwise, after being transported to the processing device 40, the film F cannot be properly gripped due to the positional relationship between the gripping rollers (not shown) of the processing device 40 and the patrone Pt loaded in the processing device 40. Because. Subsequently, the operator inserts the cartridge Pt into the empty adapter 20 that has reached the upper set position as the chain 13 moves. At this time, if the drawing length of the film F is longer than 45 mm, the adapter 2
Since the patrone Pt cannot be inserted at 0, the operator must adjust the length of the drawer and insert the patrone Pt into the adapter 20 again. With this configuration, after the patrone Pt is transported to the processing device 40, it is possible to prevent the film F from being caught due to an excessively long drawing-out length. The inserted patrone Pt is held in the adapter 20 by the spring member 23. However, auxiliary means for preventing the patrone from dropping may be provided.

When the detecting device (not shown) detects that the adapter 20 has reached the left take-out position in FIG. 1, the actuator 31 is driven, whereby the rod 32 is moved.
It extends as shown in FIG. At this time, the end of the rod 32 pushes the cartridge Pt, and at the same time, the end face of the arm 32a pushes the film F. Thereby, the patrone Pt is extruded so as to move parallel to the adapter 20 and is loaded at a predetermined position in the processing device 40. If, for some reason, the rod 32 cannot push out the cartridge Pt and the adapter 20 passes the take-out position while holding the cartridge Pt, the sensor 50 detects this and issues an alarm or The movement of the chain 13 is stopped.

When the patrone Pt is supplied to the processing unit 40, the actuator 31 pulls back the rod 32, and the light-shielding shutter 41 of the processing unit 40 moves downward to close the patrone entrance. As a result, external light is
To prevent the exposed film F from being further exposed to light. In the processing device 40,
A roller (not shown) grips and rotates the leading end of the film F pulled out from the cartridge by 43 to 45 mm and delivers it to a developing unit (not shown). After the processing of the first patrone Pt is completed, the light shielding shutter 41 is moved upward to receive the next patrone Pt.

According to the present embodiment, since the rod 32 is provided with the arm 32a, the posture of the cartridge 32 when pushing out the cartridge Pt from the adapter 20 can be regulated. The patrone Pt can be loaded in the posture. In addition, since the length of the film F drawn out is regulated by the film holding portion 22, it is possible to prevent a problem such that the leading end of the film F is caught on the gripping roller when the cartridge Pt is extruded.

FIG. 6 is a view similar to FIG. 5, showing a modification of the adapter. In FIG. 6, instead of providing a spring member, the adapter 120 has a magnet 123 disposed near the film holding section 122 on the mounting surface 120a. Since the patrone is made of iron, the magnet 123
The cartridge pt can be sucked and urged toward the film holding portion 122 side. Thereby, patrone p
Regardless of the diameter of t, the length of the film (not shown in FIG. 6) drawn from the cartridge pt can be regulated.

FIG. 7 is a diagram showing a modification of the configuration for controlling the attitude of the cartridge Pt when it is pushed out.
In such a modification, the rod 132 has no arm. Instead, in the modification of FIG.
The light-shielding shutter 141 of the processing device 140 has a convex portion 141a.
Are formed. The convex portion 141a has an inclined portion 141b facing obliquely downward inside the processing device 140, and an inclined portion 14a.
1b connected to a base 141c.

After the cartridge Pt has been pushed out of the adapter 20, the light-shielding shutter 141 moves vertically upward from below. At this time, if the patrone Pt does not move in parallel with the adapter 20 and its posture is disturbed, as the light-shielding shutter 141 moves, the inclined portion 1 moves.
41b presses the side edge of the pulled-out film F to move the cartridge Pt to an appropriate position.
Thereby, the gripping roller (not shown) of the processing device 140
Means that the leading end of the film F can be firmly grasped.

FIG. 8 is a diagram showing a leading end of a film according to another embodiment. In FIG. 8, a round notch C1 is formed at the tip of the film F1. In the above-described embodiment, a so-called 135 type film is set in the processing apparatus without using a short reader described later. However, when the front end of the film is formed so that the center protrudes or is formed with a straight edge
When the film is wound with a small curvature in the processing device, the center of the leading edge of the film abuts on a transport roller (not shown) due to the strong stiffness, causing the roller to wear or causing the film to jam. Might be.
Therefore, if the notch C1 is formed at the leading end of the film F1 as in the present embodiment, it is possible to prevent contact with the transport roller as much as possible even if the film F1 is wound around with a small curvature.

On the other hand, a so-called APS film or 1
Small films called type 10 are set in a processing apparatus using a short reader. The short leader is an elongated resin plate attached to the tip of an APS film or a 110-type film, and has a function of improving transportability in a processing apparatus.

FIG. 9 is a diagram showing a tip of a short leader according to another embodiment. In FIG. 9, a round notch C2 is formed at the tip of the short leader S1. Since the short leader S1 itself is relatively strong, a notch C2 is provided so that even when the short leader S1 is routed with a small curvature, contact with the transport roller is prevented as much as possible.

FIG. 10 is a view showing a modification of the leading end of the film. In FIG. 10, a notch C3 having an isosceles triangle shape is formed at the tip of the film F2. As in the embodiment of FIGS. 8 and 9, by forming the notch C3 at the leading end of the film F2, it is possible to prevent contact with the transport roller and the like as much as possible even when the film F has a small curvature.

Although the present invention has been described with reference to the embodiments, it should be understood that the present invention should not be construed as being limited to the above embodiments, and that modifications and improvements can be made as appropriate. is there. For example, the means for urging the patrone in the adapter is not limited to a spring member or a magnet, and it is also possible to use a sponge or the like.
