Field of the Invention The present invention relates to a film magazine used when printing is performed on a negative film or the like using a printer device, and more specifically, a plurality of films are sequentially wound into a roll shape. The present invention relates to a film magazine provided with a rewinding mechanism for rewinding a roll in order to sequentially release the stored film.

[0002]

2. Description of the Related Art As an example of the above film magazine,
A photographic printing cartridge described in JP-A-56-42227 is known. In this photographic printing cartridge, as shown in FIG. 9, a roll 20 of a long storage tape 203 wound in a fixed direction by a core 201.
6, a plurality of piece films PN are sequentially sandwiched and stored, and the stored piece films PN are sequentially extracted by rewinding the wound storage tape 203 to expose the printer device. It is configured to be conveyed to a copy and printed on photographic paper.

[0003]

In the film magazine according to the above-mentioned prior art, since the axis of the core 201 for winding the storage tape 203 together with the piece film PN is fixed at a predetermined position, it is formed as described above. Roll 20
The passing path P of the piece film PN was inevitably changed as the outer diameter of 6 increased in accordance with the number and length of the film to be wound. Therefore, in order to smoothly put in and take out the piece film PN,
The position of the pressure roller 207 that presses the roll 206 from the outside also needs to be adjusted according to the change in the passage P of the piece film PN, and between the pressure roller 207 and the film transport roller 208, the piece film PN.
It is necessary to adjust the position of the guide member 209 that guides the film in the same manner, and as a result, the structure of the entire film magazine becomes complicated.

Therefore, in view of the drawbacks found in the prior art film magazines exemplified above, the object of the present invention is to increase the outer diameter of the roll to be formed according to the number and length of the film to be wound. Another object of the present invention is to provide a film magazine in which the passing path of the film moving to the roll does not change.

[0010]

In order to achieve the above-mentioned object, the contract of the present invention
The film magazine according to Requirement 3 is used to order multiple films.
Next, the winding mechanism for winding and storing in a roll

This is a basic configuration of a film magazine, which stores a plurality of spliced films, in particular, a film wound in a roll shape on the outer periphery of a shaft member is rolled and wound by a member abutting from the outer peripheral side. Can be applied to things .

In this way, in the structure in which the film wound in a roll shape on the outer periphery of the shaft member is rolled from the outer peripheral side and wound, the film released from the formed roll or stored in the roll is about to be stored. Even if a pulling force is applied to the film from the film supply roller, this pulling force always works only on the film that is located on the outermost peripheral side at that time, and is located in the inner layer near the center of the formed roll. Since it does not reach the film being wound, it is convenient because the rolls are not squeezed toward the center side and the films rub against each other, as compared with a configuration in which a core for winding the film is driven to form a roll.

Further, in such a structure in which the film wound in the form of a roll on the outer periphery of the shaft member is rolled from the outer peripheral side and wound, the speed of the film when entering the roll or being released from the roll is Since it always matches the peripheral speed of the member that rolls the film from the outer peripheral side (by friction), simply by keeping the driving speed of the rolling member constant,
Since the speed of the film when entering or releasing the roll is constant regardless of the increase or decrease in the radius of the formed roll, the film is supplied to the exposure section of the printer at a constant speed. It is convenient that the mechanism for doing so can be configured inside the film magazine.

More specifically, as in the invention of claim 4 , as a plurality of cylindrical support members, a first roller having a fixed shaft center and a relative movement with respect to the first roller are possible. , First roll formed by long film
It suffices to provide a second roller that is pressed against the roller.

In order to achieve the above object, the present invention is a contract.

It This is a basic configuration of a film magazine, which stores a plurality of spliced films, in particular, a film wound in a roll shape on the outer periphery of a shaft member is rolled and wound by a member abutting from the outer peripheral side. It can be applied as another configuration.

More specifically, as in the invention of claim 6 , means for pressing the shaft member toward the belt member is provided, and a boundary portion between the roll formed on the outer periphery of the shaft member and the belt member ( That is, the position of the portion where the film enters the roll and is released from the roll) may be unchanged regardless of the increase or decrease in the radius of the roll.

Other features and advantages of the present invention will become apparent from the following description of the embodiments with reference to the drawings.

[0018]

BEST MODE FOR CARRYING OUT THE INVENTION With regard to the film magazine according to the present invention, the attached drawings are provided on the assumption that a photograph is reprinted from a piece film using a printer processor (an example of a printer device) based on an order received from a customer. I will explain while referring to it.

(Issuance of Order Sticker) First, under the premise of this embodiment, when the DPE store receives a reprint order of a photograph from a customer, as shown in FIG.
At the same time as receiving the negative sheet 1 containing the
Ordering time, frame position to be reprinted and number of each reprint,
Also, an order sticker 3b is printed by printing order data including a store code and information such as an order number as a bar code, the order sticker 3b is attached to the order piece 3, and the order sticker 3b is inserted into the negative sheet 1. The order piece 3 is formed by forming an opaque layer on a transparent film material having the same shape as the piece film 2.
Only the portion corresponding to the perforation 2a of the piece film 2 is left as a transparent area, and this transparent area forms the pseudo perforation 3a. Therefore, the transport state of the order piece 3 can be monitored by detecting the pseudo perforation 3a with an optical sensor. Since the order piece 3 may have a shape and elasticity similar to those of the piece film 2, of course, an unexposed negative film or a fully exposed negative film may be cut and used. In that case, the pseudo perforation 3a is a piece. It is exactly the same as the perforation 2a of the film 2.

(Loading into Film Magazine) Next, all the order pieces 3 and each piece film 2 are stored in the film magazine 10a according to the present invention. As shown in FIGS. 2 and 3, the film magazine 10a includes a first winding core 11 (an example of a storage tape winding spool) for winding a long storage tape 13 and a first winding core 11a. Winding core 1
It has the 2nd winding core body 12 for rewinding the storage tape 13 on 1 (1st winding core body 11 and 2nd winding core body 12).
Cooperate to form a winding mechanism and a rewinding mechanism). The first winding core 11 and the second winding core 12 can be rotationally driven in arbitrary directions by the step motors M1 and M2, respectively. FIG. 2 shows a state before the winding of the storage tape 13 onto the first winding core 11 is started, and FIG.
Shows the state in which the winding of the storage tape 13 onto the first winding core 11 has advanced.

As can be seen from FIG. 2, the width of the storage tape 13 is set to a size capable of storing a piece film carrying 6 frames. As can be understood from FIGS. 2 and 3, the shaft core of the first winding core body 11 has the elongated hole 1
It is provided so as to be movable within 1a. The long hole 11a is formed of an arc centered on the rotation axis X of the pulley 15 for rotating the first winding core 11 by the step motor M1, and the first winding core 11 is driven by its own weight. Since it is always urged downward, the storage tape 13 wound on the first winding core 11 is pressed against the fixed roller 16 as a result. Therefore, when the piece film 2 is sequentially supplied onto the guide table 17 at the time of winding the storage tape 13 onto the first winding core 11, the piece film 2 is fed by the feed roller provided on the guide table 17. The roll of the storage tape 13 that is introduced onto the roll forming portion of the first winding core 11, that is, the surface of the storage tape 13 by 18 (an example of a supply mechanism) and is wound on the first winding core 11. Sequentially stored in R1. At this time, the piece film 2 is the same as the piece film 2.
Will be stored in the roll R1 of the storage tape 13 such that the longitudinal direction of the storage tape 13 intersects the winding direction of the storage tape 13.

(Mounting of Film Magazine to Piece Film Supply Device) Next, the film magazine 10a storing the plurality of piece films 2 is mounted to the piece film supply device 100 of the printer processor. After mounting,
When the roll-shaped storage tape 13 wound on the first winding core 11 is rewound on the second winding core 12, a plurality of stored piece films 2 are sequentially guided in the reverse sequence. The piece film 2 released onto the sheet 17 is sequentially collected by an extraction roller 19 (an example of a collecting mechanism) in a direction intersecting the winding direction of the storage tape 13, and the piece film supply device 1 of the print processor.
Will be transported to 00.

(Reprint Operation) FIG. 4 is a block diagram of the printer processor. The block diagram of FIG. 4 shows a state in which reprinting is performed by processing the piece film 2. The printer processor is provided with a piece film supply device 100 that feeds out a large number of stored piece films 2 one by one, and the film magazine 10a according to the present invention can be attached and detached thereto in a cassette manner. In addition, the printer processor displays the image of the piece film 2 on the photographic paper 4
It has an exposure unit 8 that projects and exposes the photographic paper 4, a development processing unit 9 that develops the exposed printing paper 4, and a controller 7 that controls the operation of each component.

An operation console 71 for inputting various control instructions and a monitor 72 for displaying an image of the piece film 2 read by the scanner 30 are connected to the controller 7. When the piece film 2 to be printed is sent to the exposure unit 8 by the piece film supply device 100, the image of the printing target frame of the piece film 2 is read by the scanner 30, and the image information is sent to the controller 7. The controller 7 determines the exposure condition based on the obtained image information. Then, an image that would be obtained by projecting and exposing the photographic printing paper 4 under the determined exposure conditions is simulated and displayed on the monitor 72.

In the exposure section 8, an exposure light source 81 and a light control filter 82 for adjusting the color balance of the irradiation light from the exposure light source 81 by moving the yellow, magenta, and cyan filters in and out of the exposure light path. A mirror tunnel 83 for uniformly mixing the light whose color balance has been adjusted by the light control filter 82,
A printing lens 84 for forming an image of a frame to be printed on the printing paper 4, a shutter 85, and an auto negative mask 86 forming a transport line for transporting the piece film 2 at an exposure point are provided. In addition to the scanner 30 described above, the auto negative mask 86 also incorporates a drive roller 87 for negative transfer and a negative detection sensor 31. The photographic printing paper 4 is pulled out from the photographic printing paper magazine 92 by the driving roller 91 for conveying the photographic printing paper, and after the exposure processing, the development processing section 9
Sent to. In the exposure process, the controller 7
The position of each filter of the dimming filter 82 and the opening time of the shutter 85, that is, the exposure time are controlled in accordance with the exposure condition determined by. If the operator of the printer processor sees the display on the monitor 72 and an appropriate image is not obtained, he / she can input a correction instruction of the exposure condition determined from the console 71, and the controller 7 performs the exposure based on the correction instruction. Modify the conditions to determine the final exposure conditions. Then, based on the determined exposure condition, the operation of each part of the exposure unit 8 is controlled to project and expose the image of the frame to be printed on the piece film 2 on the photographic paper 4 pulled out from the photographic paper magazine 92.

The piece film supply device 100 is provided with the above-mentioned detachable cassette type film magazine 10a and the negative transfer mechanism 20 for transferring the piece film 2 pulled out from the film magazine 10a to the automatic negative mask 86. The negative transport mechanism 20 includes a first transport unit 20a arranged on the film magazine side and an auto negative mask 86.
It is divided into a second transport unit 20b arranged on the side,
A loop portion 50 for storing the piece film 2 and the order piece 3 in a state where the piece film 2 and the order piece 3 are temporarily suspended from the transport line is formed between the two. Peace film feeder 1
00 has various sensors connected to the controller 7 for operation control. For example, the storage section detection sensor 32 for confirming the mounting of the removable film magazine 10a, the piece film 2 and the order piece. The first negative detection sensor 33 that detects 3 near the exit of the film magazine 10a, the second negative detection sensor 34 that detects before the loop portion 50, the piece film 2 and the order piece 3 stored in the loop portion 50 A loop sensor 35 or the like for detecting is attached at an appropriate position.

The controller 7 is provided with an order breaker recognizing means 7a substantially constructed by a program, and by processing a signal from the first negative detection sensor 33 inputted to the controller 7, the order is recognized. Is recognized and used for subsequent processing, such as sorting of finished prints. Recognition of the order break by the order break recognition means 7a
A pattern of detection signals from the first negative detection sensor 33 for the piece film 2 and the order piece 3, or
By the signal from the specific detection point of the order piece 3,
It is easily realized by a known method. Further controller 7
Similarly, a conveyance state evaluation means 7b substantially constructed by a program is provided therein, and the piece film 2 is generated by a signal from a negative conveyance check sensor 36 that detects perforation of the piece film 2 or the order piece 3. Also, it is checked whether or not the order piece 3 is conveyed, for example, whether or not a conveyance jam has occurred.

The piece film 2 and the order piece 3 sent from the piece film supply device 100 to the exposure section 8.
As shown in FIG. 5, the order piece 3 is placed at the beginning of one order, and the piece film 2 to be reprinted is added to the order piece 3.
It is an array followed by. In other words, the order piece 3 divides the order of the additional print order. Order sticker 3b attached to order piece 3
Since the data required for reprinting is recorded in the bar code on the, the bar code is read,
The controller 7 can detect information such as what image of what frame of the piece film 2 following the order piece 3 and how to print it, and controls the operation of each member of the exposure unit 8 in accordance with the information.

Next, the operation of the piece film supply device 100 will be described. When the film magazine 10a in which the order piece 3 and each piece film 2 are wound is mounted on the piece film supply device 100, the storage section detection sensor 32 senses the mounting and mounts the film magazine 10a on the controller 7. Inform. Auto negative mask 8
If 6 is in the negative receiving state, step motor M1,
When M2 is actuated to start rewinding the storage tape 13 wound on the first winding core body 11 to the roll R2 side on the second winding core body 12, first, the order piece 3 causes the extraction roller 19 to move.
Sent out from. When the order seal 3b is detected by the first negative detection sensor 33, the order piece 3 is stopped at a position where the barcode can be read by the barcode reader 40. When the reprint information of this order is sent to the controller 7 through the bar code reader 40, the solenoid of the loop section 50 is activated and the passage of the order piece 3 is permitted.

The order piece 3 remains as it is in the second transfer section 2.
0b, it passes through the auto negative mask 86 and is discharged to the outside, but then the piece film 2 is sent out from the extraction roller 19 and sent to the auto negative mask 86 by the first transport unit 20a and the second transport unit 20b. However, at that time, the negative detection sensor 3 indicates that the tip of the piece film 2 reaches the first driving roller 87 of the auto negative mask 86.
When detected by 1, the drive roller 87 of the auto negative mask 86 conveys the piece film 2. This avoids the inconvenience caused by the difference in the transport speed between the second transport unit 20b and the auto negative mask 86. The piece film 2 sent to the auto negative mask 86 is aligned so that the frame to be exposed comes to the exposure point, is exposed in a predetermined step, and is discharged after the processing is completed. In this way, the piece films 2 are sequentially exposed,
The conveyance status of the piece film 2 and the order piece 3 is monitored by the negative conveyance check sensor 36 that detects the perforations 2a and the pseudo perforations 3a. If the conveyance clogging occurs in the auto negative mask 86, the loop lid (shown in the figure). Not opened) allowing the subsequent piece film 2 to loop upwards.

Until the exposure processing of all the piece films 2 belonging to one order is completed, the order piece 3 of the next order waits at the reading position of the bar code reader 40. Instead of pasting the order sticker 3b in which the additional printing information is recorded as a bar code on the order piece 3, the bar code may be directly recorded on the order piece 3. Furthermore, instead of the bar code method, the order piece 3 itself can be used as a mark sheet. In this case, the barcode reader 40 is replaced with a mark sheet reader. Other recording methods are magnetic,
Various methods such as optical can be used.

[Other Embodiments] <1> In the above embodiment, the winding mechanism is provided with a drive roller that is rotationally driven to wind the long storage tape into a roll shape, and is separated from each other during the winding. I explained about a film magazine that stores multiple films (piece films) in the above state by sequentially sandwiching them between storage tapes, but in addition, splicing multiple films in the longitudinal direction to form a long film shape. Targeting the integrated one, rather than sandwiching it between storage tapes,
The roll may be formed by winding only the film on the shaft member or the like. The integrated long film may be a piece film connected, a film of 24 frames or 36 frames connected, or a combination of a piece film and a film.
An order piece in which exposure information and the like are written may be inserted between these films.

As an example of a concrete structure for realizing this, a structure such as the film magazine 10b shown in FIG. 6 as the second embodiment may be used. Here, the winding mechanism is, as shown in FIG.
A cylindrical shaft member 21 capable of winding F on the outer circumference, and a drive belt 22 for rotating the shaft member 21 (an example of a drive unit).
Is equipped with. The drive belt 22 is wound around the shaft member 21 and pulleys 24b and 24c having a fixed shaft center, and a tension pulley 25 having a movable shaft center,
The pulley 24c is a drive pulley that is driven to rotate by the motor M. When one end of the long film LF is fixed to the shaft member 21 and the pulley 24c is driven in a predetermined direction, the drive belt 22 makes a revolving motion and the shaft member 21 is rotationally operated. The roll R3 of film is formed by being wound around the outer periphery of the shaft member 21. The outermost layer of the roll R3 is constantly pressed against the fixed idler roller 24a by the action of the drive belt 22 and the tension pulley 25 and the action of the weight of the shaft member 21, and the shaft member 21
Is movably supported in the long hole 23, so that the shaft member 21 moves upward in the long hole 23 in accordance with the increase in the radius of the roll R3. As a result, as shown in FIG. 6B, the passage P of the long film LF that moves to the roll R3 becomes constant regardless of the increase in the radius of the roll R3.

The long film LF is supplied by the supply roller 26.
If the drive belt 22 is reversed while pulling the film outside the film magazine (on the right hand side in the figure), the long film L
F is released from the roll R3 and is conveyed to the exposure unit of the printer apparatus. At this time, the passing path P of the long film LF pulled out from the roll R3 is irrelevant to the decrease in the radius of the roll R3 by the same principle. Will be constant.

<2> In the above second embodiment, a roll is formed by splicing a plurality of films and integrating them into a long film, and winding them around a shaft member or the like without using a storage tape. As a specific configuration for making the roll, the roll is formed by the rotating force of the shaft member around which the long film is wound. Instead of this, the third roll shown in FIG.
A film magazine 10c for storing a long film by rolling a roll of a film formed on a shaft member from the outside in the radial direction as in the embodiment may be adopted. Here, as shown in FIG. 7A, the winding mechanism has a cylindrical shaft member 27 capable of winding the long film LF around the outer periphery, and the shaft member 27 has a fixed shaft core. And a long hole 29a for the first roller 28
It is tightly surrounded by the second rollers 29, 29 that are relatively movable inside. Therefore, a compression spring (not shown) for urging the second rollers 29, 29 toward the first roller 28 is provided between the elongated holes 29a, 29a and the second rollers 29, 29. . As a result, the second rollers 29, 2
9 is the roll R4 of the long film LF, the first roller 2
It will be pressed toward 8.

The first roller 28 is a drive roller that is rotated by a motor M, and the drive belt 22 is wound around the first roller 28, the second rollers 29 and 29, and the tension pulley 25. . Therefore, one end of the long film LF is fixed to the shaft member 27,
When the first roller 28 is driven in a predetermined direction, the drive belt 2
2 makes an orbital movement in the direction of the arrow, the second roller 2
9, 29 also rotate in the same direction and speed as the first roller 28,
The long film LF is wound around the outer periphery of the shaft member 27, and the roll R4 as shown in FIG. 7B is formed.
As shown in FIG. 7-B, the second rollers 29, 29 move upward in the long hole 29a in accordance with the increase in the radius of the roll R4, so that the lower outer periphery of the roll R4 has a fixed axis. It is always pressed against the first roller 28 that has been pressed. Therefore, the passage P of the long film LF that moves to the roll R4 is constant regardless of the increase or decrease in the radius of the roll R4. In this configuration, the roll to be formed rolls from the outside rather than being wound by the driving force of the shaft member 27,
Unlike the second embodiment, the long film LF has a roll R4.
The moving speed at the time of shifting to and the moving speed at the time of being released from the roll R4 are constant regardless of the change in the radius of the roll R4.

<3> In the third embodiment, the shaft member is used as a specific structure for storing the long film by rolling the roll of the film formed on the shaft member from the outside in the radial direction. The roll of the long film formed on the outer periphery of is rolled and stored while being supported from the outer peripheral direction by a plurality of cylindrical members. In addition, the fourth embodiment shown in FIG. As in the embodiment, the film magazine 10d may be configured to roll and store a roll of a long film from the outer peripheral direction while being supported by a belt member. Here, the winding mechanism includes a cylindrical shaft member 37 capable of winding the long film LF around its outer circumference, and a roll R5 formed by the long film LF wound around the outer circumference of the shaft member 37, in the outer circumferential direction thereof. It has a belt member 22 for supporting from. The belt member 22 includes rollers 38a, 38b, which have fixed axes.
38c and the tension roller 25, which is supported by a tension spring, and is wound around the shaft member 37. The roller 38a is a drive roller that is driven to rotate by the motor M. Further, the shaft member 37 is movably supported in an elongated hole 37a extending in the vertical direction, and is directed toward the fixed roller 39 by a tension spring 42 (an example of a means for pressing the shaft member toward the belt member). It is pulled and urged.

Therefore, the long film L is attached to the shaft member 37.
If one end of F is fixed and the roller 38a is rotated in a predetermined direction, the shaft member 37 is rotated by the belt member 22 and the long film LF is wound around the outer periphery of the shaft member 37. As shown in FIG. 8B, even if the radius of the roll R5 of the long film LF formed on the shaft member 37 increases, the position of the boundary portion between the roll R5 and the belt member 22 does not change, in other words, The passing path P of the long film LF that moves to the roll R5 is constant regardless of the increase or decrease in the radius of the roll R5.
