JPH04369647A - Housing container for long-length photosensitive sheet - Google Patents

Abstract

PURPOSE:To prevent the projecting part of a long-length photosensitive sheet from being easily drawn in a housing container. CONSTITUTION:When a negative film 200 is moved in a direction that it is drawn in a negative film cartridge, a roller 251 is interposed between a guide part 250 and the film 200 and it intrudes the film 200. Thus the film 200 is prevented from being drawn in. On the other hand, the roller 251 is brought into contact with both of the guide part 250 and the film 200 when the film 200 is moved in the direction that it is drawn out from the negative film cartridge (carrying direction). However, since it does not receive force to the lower part from the surface of the guide part 250, it is only brought into contact with the film 200 by small pressure and the film 200 is not prevented from being carried.

Description

[Detailed description of the invention]

0001

[Field of Industrial Application] The present invention relates to a storage container for long photosensitive sheets used in peel-apart type instant photographic devices, etc. Concerning a seat storage container.

0002

2. Description of the Related Art A peel-apart type instant photographic device uses a combination of a photosensitive sheet (negative film) and a positive sheet. For peel-apart cameras (instant photography devices), the supplies used (
Because the photosensitive sheet and positive sheet) are small in size,
A photosensitive sheet and a positive sheet are combined in advance and used as a pack film.

However, as the size of instant photographic devices increases, when a photosensitive sheet and a positive sheet are used as a pack film, the size of the pack film increases, making it difficult to handle and impractical. be. For this reason, in an instant photographic apparatus that uses a relatively large supply, a method is adopted in which the photosensitive sheet and the positive sheet are separated and placed on the apparatus in an independent state.

[0004] The photosensitive sheet used in such an instant photographic device is generally long, and specifically, as shown in FIGS. A long piece (for example, 3 pieces) rolled into a roll with the
A special cartridge is used in which a photosensitive sheet T (capable of photographing 6 images) is loaded. Further, the long photosensitive sheet T has a front surface made of a photosensitive layer having photosensitivity, and a back surface made of light-shielding paper so that the above-mentioned photosensitive layer does not react to irradiation from the back side.

FIGS. 15(a) and 15(b) show an example of a conventional storage container for a long photosensitive sheet, and the storage container 401 is resin-molded into a cylindrical shape containing a rolled long photosensitive sheet T. In order to facilitate molding and loading of the long photosensitive sheet T, it is divided into two planes including the axis, and as shown in the figure, the divided storage container 40
A fitting part for coupling and a guide part 402 for feeding out the long photosensitive sheet T are formed in each of the divided parts.

When storing the long photosensitive sheet T in the storage container 401, a divided lower storage container is installed, and the leading end of the rolled long photosensitive sheet T is placed in the feeding portion 402. Place it so that it protrudes a few mm from the outside. Thereafter, the storage container 401 is assembled by covering the storage container on the upper side and fitting the fitting portions to connect the storage container on the lower side and the storage container on the upper side.

Therefore, in the instant photographic apparatus, the long photosensitive sheet T is pulled out from the storage container 401 using a pull-out roller.

[0008]

[Problems to be Solved by the Invention] However, according to the conventional storage container in which a long photosensitive sheet is stored in roll form, the long photosensitive sheet (i.e., the storage container) must be replaced depending on the type of positive sheet. In this case, it is necessary to remove the storage container installed in the instant photography device, and if you apply vibration to the storage container or accidentally press the tip of the long photosensitive sheet, the long photosensitive sheet may become unreliable. Since the protruding portion of the sheet is drawn into the storage container, there is a problem that the sheet may not be able to be used again in that state.

[0009] If the protruding portion of the long photosensitive sheet is drawn into the storage container, since it is photosensitive, it is impossible to open the storage container in a bright room and pull out the tip of the long photosensitive sheet. First, since the user is required to work in a completely dark room, there is also the inconvenience that the user cannot easily pull out the device.

[0010] Furthermore, with the conventional storage container storing the long photosensitive sheet in roll form, it is possible for the user to accidentally pull out the long photosensitive sheet from the storage container after it has been removed from the instant photographic device. In this case, there was also the problem that the pulled out portion could no longer be used.

Furthermore, depending on the amount pulled out, it becomes impossible to place the storage container inside the instant photographic device, so it is necessary to cut off the excess pulled out portion, but if it is not cut properly, the instant There was also the inconvenience that it could get caught in the conveyance path of the photographic device, causing a jam.

The present invention has been made in view of the above, and its first object is to prevent the protruding portion of a long photosensitive sheet from being easily drawn into a storage container.

[0013] Furthermore, the present invention has been made in view of the above, and a second object is to prevent a long photosensitive sheet from being easily pulled out from a storage container when removed from an instant photographic device or the like. .

[0014]

[Means for Solving the Problems] In order to achieve the above-mentioned first object, the present invention provides a light-shielding storage section for storing a roll-shaped elongated photosensitive sheet, and a light-shielding storage section for storing the elongated photosensitive sheet in the form of a roll. A storage container for a long photosensitive sheet, which is used by having a guiding part and protruding the long photosensitive sheet from the guiding part, sandwiching the protruding part of the long photosensitive sheet, and pulling it out. The present invention provides a storage container for long photosensitive sheets, in which a projection holding means for preventing the projections of the long photosensitive sheets from being drawn into the storage section is provided on the guide section.

Further, in the above-described structure, when the long photosensitive sheet is pulled out from the storage section, the protrusion holding means moves in the direction of releasing the pressure on the long photosensitive sheet, and also moves in the direction of releasing the pressure on the long photosensitive sheet. When the long photosensitive sheet is drawn in, it is desirable to include a moving member that moves in a direction to press the long photosensitive sheet.

Further, in the above-described structure, the movable member storage container having a triangular cross section with a height on the conveying direction side of the long photosensitive sheet when the surface of the long photosensitive sheet is one side is used as the guiding section. It is desirable that the movable member be housed between the movable member storage container and the elongated photosensitive sheet so as to be movable in the transport direction and the opposite direction.

Further, it is preferable that the aforementioned moving member is a rolling member having a circular cross section or a wedge-shaped cross section.

[0018] Furthermore, in the above-mentioned configuration, the guiding part is
The structure is such that a long photosensitive sheet is guided using an upper guide member and a lower guide member, and the protrusion holding means is an upper portion having a bulge in the conveying direction side of the long photosensitive sheet provided on the upper guide member side. A rolling member having a circular cross section is placed in a movable member storage container formed by a slope surface and a lower slope surface provided on the lower guide member side and having a bulge in the direction opposite to the conveying direction of the long photosensitive sheet. It is desirable that the structure accommodates a moving member consisting of.

Further, the above-mentioned protrusion holding means includes an arm portion rotatably supported with respect to a fulcrum provided in the guiding portion, and a long photosensitive member that is rotatably supported with respect to the arm portion. Preferably, it consists of a rotating member that abuts the seat.

Furthermore, in order to achieve the above-mentioned second object, the present invention includes a light-shielding storage section for storing a roll-shaped long photosensitive sheet, and a guiding section for pulling out the long photosensitive sheet. A storage container for a long photosensitive sheet, which is used by protruding a long photosensitive sheet from the guiding part, sandwiching the protruding part of the long photosensitive sheet, and pulling it out. The present invention provides a storage container for a long photosensitive sheet, which is provided with a fixing means for fixing the protruding portion of the photosensitive sheet to the guiding portion.

Further, the above-mentioned fixing means fixes the protruding portion when the long photosensitive sheet storage container itself is removed from an instant photographic device, etc., so that the long photosensitive sheet storage container itself It is desirable to release the fixation of the protruding portion when it is set in the device or the like.

[0022]

[Function] In the long photosensitive sheet storage container of the present invention, the protrusion holding means prevents the protrusion of the long photosensitive sheet from being drawn into the storage portion. For example, when a long photosensitive sheet is pulled out from the storage section, the moving member of the protrusion holding means moves in a direction to release pressure on the long photosensitive sheet, allowing the long photosensitive sheet to be pulled out. When a long photosensitive sheet is drawn into the storage section,
The long photosensitive sheet is held by moving in the direction of pressurizing the long photosensitive sheet.

Furthermore, in the storage container for a long photosensitive sheet of the present invention, the fixing means fixes the protruding portion of the long photosensitive sheet to the guiding portion. For example, when the long photosensitive sheet storage container itself is removed from an instant photographic device, etc., the protruding portion is fixed, and when the long photosensitive sheet storage container itself is set in the instant photographic device, etc., the protruding portion is fixed. Release the fixation of the part.

[0024]

[Example] Hereinafter, the case where the long photosensitive sheet storage container of the present invention is used in an instant photographic device will be described as Example 1, Example 2, Example 3, Example 4, Example 5, and Example 6 and Example 7 will be described in detail in this order with reference to the drawings.

[Example 1] First, a storage container for the long photosensitive sheet of Example 1 (hereinafter referred to as negative film cartridge 2)
01), the positive sheet, which is an image-receiving sheet, will be described.

■Configuration of positive sheet assembly In the instant photographic apparatus used in Example 1, the positive sheet (
It is used as a positive sheet assembly by attaching accessories such as a pod containing developer and a trap mask for retaining excess developer after spreading.

FIG. 1 shows a positive sheet assembly 100.
The positive sheet assembly 100 includes a black leader 102 affixed to the tip of the positive sheet 101 on the image receiving surface side, and a leader 10 containing developer.
Pod 103 pasted on 2 and positive sheet 1
A tip mask 104 arranged to improve the image at the end of the image area 01 (area a×b in FIG. 1),
It is composed of both side masks 105, a trap mask 106, and a rail member 107 pasted on both side masks 105.

Here, the developer flowing out of the pod 103 can be uniformly spread on the positive sheet 101 to a thickness that is almost the same as the thickness of the rail member 107 and both side masks 105.

The amount of developer in the pod 103 is larger than that required for image formation so that the developer is sufficiently distributed to the rear end of the image area.
It is enclosed inside. After the excess developer is uniformly spread to the rear end of the image area, it is transferred to a trap mask 106 (section D in FIG. 1) and a negative film 200 (section D' in FIG. 2), which is a long photosensitive sheet to be described later. stored between. This prevents excess developer from spilling out into the apparatus, adhering to the developing roller, conveyance path, etc., and contaminating them.

(2) Construction of Negative Film and Negative Film Cartridge The long photosensitive sheet of Example 1 uses a negative film 200 wound into a roll, as shown in FIG. The negative film 200 is made of a long photosensitive strip material (for example, 36 images can be taken), and is wound into a roll with the latent image forming surface (photosensitive surface) inside, as shown in FIG. It is stored in a negative film cartridge (container for storing the long photosensitive sheet of Example 1) 201 .

The negative film cartridge 201 is resin-molded into a cylindrical shape containing the rolled negative film 200, and is divided into two planes including the axis in order to facilitate molding and loading of the negative film 200. The configuration is as follows.

As shown in FIGS. 3(a) and 3(b), the divided portions of the divided negative film cartridge (upper container 201a and lower container 201b) have fitting portions 202 and 203 for connection, respectively. , a negative guiding section 204 and a negative feeding section 205 for feeding out the negative film 200 are formed. The fitting parts 202 and 203 are the fitting part 2
02 is formed to cover and wrap the fitting part 203, and prevents the negative film 200 from being exposed to light due to the entry of ambient light. Similarly, in order to prevent disturbance light from the negative feeding section 205, a light-shielding elastic member is attached inside the negative guiding section 204 at one end to the upper container 201a, and the other end is in contact with the negative film 200 with its own elastic force. (For example, mylar with a flocked cloth attached) 206 is provided.

[0033] Also, the negative guiding part 204 of the upper container 201a
As shown in the figure, there is a wedge-shaped guide portion 250 having a surface that widens in the direction in which the negative film 200 is conveyed.
is provided. FIG. 4 shows a cross-sectional view of the guide section 250. A cylindrical roller 251 is movably housed between the inner surface of the guide section 250 and the negative film 200. It constitutes a section holding means. When the negative film 200 moves in the direction in which it is drawn into the negative film cartridge 201, as shown in FIG. It bites in and prevents the negative film 200 from being drawn in. On the other hand, as shown in Figure (b),
Negative film 200 is negative film cartridge 201
When moving in the direction in which the rollers 251 are pulled out (conveyance direction), the rollers 251 come into contact with both the guide section 250 and the negative film 200, but do not receive any downward force from the surface of the guide section 250, so the negative film 200 They come into contact with only a slight pressure and do not interfere with the conveyance of the negative film 200.

Therefore, the negative film cartridge 201
Even if the user accidentally pushes the leading end of the negative film 200 into the negative film cartridge 201, the negative film 200 is held by the guide portion 250 and the rollers 251, so that it is pulled into the negative film cartridge 201. Negative film cartridge 2 can be used safely without any special precautions.
01 can be handled. In addition, FIGS. 4(a) and (b)
Although not shown in ), the roller 251 is the negative film 2.
00 and move together with the negative film 200, a spring member or a pressure member that presses the roller 251 against the negative film 200 with a slight force that does not hinder the movement of the negative film 200 is attached to the inner surface of the guide portion 250. If it is provided between the rollers 251 and 251, the operation can be performed more reliably.

When storing the negative film 200 in the negative film cartridge 201, the lower container 201b is installed, and the tip of the roll-shaped negative film 200 is placed in the lower container 201b so that it protrudes from the negative feeder 205 by a few mm. Place it. Thereafter, the upper container 201a is placed on the upper container 201a, and the fitting portions 202 and 203 are fitted to connect the upper and lower containers 201a and 201b.

[0036] The upper and lower containers 201a and 201b are not limited to the above-mentioned method, but may also be connected using screws, heat seals, or the like. Note that a foot 207 is provided at the bottom of the lower container 201b to ensure that the negative film cartridge 201 is mounted in a fixed position in the main body of the apparatus. Also, container 2
On the side of 01a, there are marks M4, M5, M6 indicating the type of negative film 200 (details are omitted, but
(forming a predetermined negative film type identification code) is provided.

As shown in FIG. 3(b), the negative guiding section 204 is provided with a notch 210 that fits into a pair of pull-out rollers 312 for pulling out the negative film 200.
When the negative film cartridge 201 is installed in the main body of the apparatus, the negative film 20 is pulled out by the pull-out roller pair 312.
The structure is such that 0 is reliably nipped.

■ Overall structure and operation of the device FIG. 5 shows the overall structure of an instant photographic device in which the negative film cartridge 201 of Embodiment 1 is placed. An optical system unit 301 that forms an image at a predetermined position (exposure surface), a negative film 200 that is transported and exposed to the predetermined position, and further aligned and overlapped with a positive sheet assembly 100, and a developer is spread between them. The transport unit 302 is configured to transfer and form an image onto the positive sheet assembly 100.

The optical system unit 301 includes a contact glass 303, a first traveling body 3 consisting of a first mirror and a light source.
04, a second traveling body 305 consisting of a second mirror and a third mirror, a third traveling body 307 consisting of a lens 306, a fourth mirror, and a fifth mirror, and a sixth mirror 308.

[0040] Here, a fluorescent lamp is used as a light source included in the first traveling body 304, and illuminates the document placed face down on the contact glass 303 while scanning it parallel to the contact glass 303. At this time, the second traveling body 305
By scanning in the same direction at 1/2 the speed of the traveling body 304, the optical path length is kept constant. Also, lens 3
06 and the third traveling body 307 to adjust the magnification and conjugate length during zooming.

As shown in the figure, the reflected light from the original is transmitted to the first, second, and
The light is then reflected by the third mirror, and further passes through the lens 306, fourth, fifth, and sixth mirrors, and is subjected to slit exposure at the exposure position A.

The conveyance unit 302 includes a negative film feed section that feeds out the photosensitive negative film 200, a negative film cutter section that cuts the fed negative film 200, and a negative film feed/exposure section that feeds and exposes the negative film 200. It consists of a positive sheet assembly conveying section, a developing section, and a developing section.

The transport operation of the negative film 200 (not shown) will be explained below, and the configurations of the negative roll film feed section, the negative film cutter section, and the negative film transport/exposure section will be shown in detail. The negative film 200 stored in a roll in the negative film cartridge 201 is conveyed onto a guide plate 314 by a pair of pull-out rollers 312a and 312b, passing between a rotary blade 313a and a fixed blade 313b, and then conveyed onto a guide plate 314 by a pair of intermediate rollers 315a. , 315b. When the leading edge of the conveyed negative film 200 is detected by the sensor S1 at the exposure position A (or after a predetermined period of time after the detection), the first traveling body 304 and the second traveling body 305 start scanning, and the negative film is The film 200 is attached to the intermediate roller pair 315
After being nipped at a and 315b, exposure and latent image formation are performed at an exposure position A on the guide plate 314.

Here, assuming that the conveying speed of the negative film 200 during exposure and latent image formation is VN, the traveling speed of the first traveling body 304 is V1, and the copy magnification is m, the conveying speed of the negative film 200 is VN. It is controlled according to the relationship: V1 = VN x 1/m.

The exposure position A is a flat surface over the slit area, and the drawing roller pair 312a, 312
b, and the nip height of the pair of intermediate rollers 315a, 315b, or higher than that. Furthermore, intermediate roller pairs 315a, 315b and pull-out roller pair 31
The peripheral speeds of 2a and 312b are almost the same, and the negative film 20
0 is detected by the sensor S1 (after being nipped by the intermediate roller pair 315a, 315b, or at the timing when exposure is started), the driving of the pull-out roller pair 312a, 312b is stopped, and an appropriate load is applied. Become free with . As a result, the negative film 200 is slightly stretched over the exposure position A, and the guide plate 314
The optical path length up to the negative film 200 surface and the transport speed can be kept constant.

The negative film 200 that has been exposed to light over a certain length and has a latent image formed thereon is once stopped, and then the rotary blade 313
By rotating a while contacting the fixed blade 313b, the sheet is cut into sheets. The stop timing of the negative film 200 is determined by counting the time t after the sensor S1 detects the leading edge of the negative film 200.

Therefore, the rear end portion of the cut negative film 200 is not exposed to light and no latent image is formed (in other words, exposure to light and latent image formation cannot be performed). Specifically, the rear end portion of the negative film 200 corresponding to at least the distance from the exposure position A to the tip of the fixed blade 313b (this distance is G) is unused, that is, a portion that is unnecessarily wasted. becomes. Therefore, the exposure position A and the cutter ( By arranging the rotary blade 313a and the fixed blade 313b, it is possible to reduce wastage of an unnecessary portion (rear end portion) of the negative film 200 that is not used for image formation.

Similarly, the leading end of the cut negative film 200 is also moved from at least the exposure position A to the intermediate roller pair 31.
Exposure and latent image formation cannot be performed over a distance longer than the distance to 5a and 315b (this distance is defined as H), but at a distance H
However, from the tip of the negative film 200, the negative film 20
The distance between the exposure position A and the intermediate roller pair 3 is set so that the distance C' (see FIG. 2) to the tip of the latent image formed on the
By arranging 15a and 315b, waste of the negative film 200 can be reduced.

Furthermore, as described above, by cutting the negative film 200 after the exposure is completely completed, changes in the transport speed due to the impact of cutting can be avoided, as compared to, for example, cutting during exposure. This allows for stable transportation. After the cut negative film 200 is turned by about 180 degrees by roller pairs 316a, 316b and guide member 317, guide plates 318a, 318
b, and is further conveyed by rollers 320 until its leading end abuts against a pair of rollers 321 (here, in a stopped state).

Next, the conveying operation of the positive sheet assembly 100 will be explained, and the configuration of the positive sheet assembly conveying section will be shown in detail. Actually, the conveyance operation of this positive sheet assembly 100 is the same as that of the above-mentioned negative film 20.
This is carried out before the conveyance, exposure, and cutting operations of 0. Unlike the negative film 200, the positive sheet assembly 100 is not photosensitive, so it can be inserted from outside the apparatus. In the instant photography apparatus of Example 1, the positive sheet assembly 100 is moved along the guide plate 311 at the lower right of the apparatus main body.
The configuration is such that the sheets are manually inserted one by one to the left side in the figure. Therefore, there is no need for a paper feeding/separating device, a paper feeding cassette, etc., and the apparatus can be made compact and inexpensive.

When the positive sheet assembly 100 is inserted along the guide plate 311 and both side guides (not shown) and its tip is detected by the sensor S5,
The insertion roller pair 322 rotates. The rollers of the insertion roller pair 322 are arranged so as to grip only the outer ends of the developer pod 103 (see FIG. 1) attached to the tip of the positive sheet assembly 100 so as not to crush the developer pod 103 (see FIG. 1). The positive sheet assembly 100 is inserted into the guide plates 323a and 323b by the insertion roller pair 322.
conveyed between the two and then stopped. This stop timing is determined by counting the time t' after the sensor S6 detects the leading edge of the positive sheet assembly 100.

Further, as shown in the figure, the conveyance path of the positive sheet assembly 100 is bent at at least one point, and external light directly enters the machine from the insertion opening of the positive sheet assembly 100 and exposes the negative film 200. We are preventing this from happening. The inserted positive sheet assembly 100 stops at a predetermined position and enters a standby state, allowing printing operation.

[0053] Here, when a predetermined print switch is pressed, the above-described transporting, exposing, and cutting operations of the negative film 200 are executed. The negative film 200 that has come into contact with the stopped roller pair 321 is bent by a certain amount by the conveying force of the roller pair 320 between the guide plate 319 and the guide plate 318b. After a predetermined amount of the negative film 200 is bent, the guide plates 324a and 324 are rotated by the rotation of the roller pair 321.
It is transported between b. The start of rotation of the roller pair 321 is determined by counting the time from when the sensor S3 detects the leading edge of the negative film 200.

By bending the negative film 200 in this way, the leading edge of the negative film 200 can be bent by the roller pair 3.
Skew correction is performed in accordance with the nip of No. 21. Negative film 20 conveyed by rotation of roller pair 321
0, the leading edge is detected by the sensor S4, and the developing roller 32
It is conveyed to the nip of 5a and 325b. Depending on the timing from the detection of sensor S4, first the insertion roller pair 322
rotates and abuts the positive sheet assembly 100 against the stopped developing rollers 325a and 325b, and skew correction is performed in the same manner as the negative film 200. after that,
The developing rollers 325a and 325b start rotating.

Next, the positive sheet assembly 100 waiting at a predetermined position is conveyed first, and then the leading edge of the negative film 200 reaches the nip between the developing rollers 325a and 325b by the rotation of the roller pair 321, and both It is transported at the circumferential speed of developing rollers 325a and 325b. At this time, a misalignment J occurs between the positive sheet assembly 100 and the negative film 200, but this misalignment J is
It is controlled to be at least smaller than C in FIG. This makes it possible to shorten the length of the negative film 200 that is cut by the amount of this deviation J, compared to a type in which the leading edge of the negative film 200 and the leading edge of the positive sheet assembly 100 are aligned and conveyed. can.

When the developing rollers 325a and 325b rotate and the spreading of the developer is completed, the developing roller 325a is separated from the developing roller 325b, creating a gap between the rollers necessary for storing the excess developer. The negative film 200 and the positive sheet assembly 100 are spread with developer by developing rollers 325a and 325b.
Tray 32 provided with a light-shielding lid 327 shown in FIG.
6 is discharged on top. The lid 327 is rotatably supported upward by a support shaft 328 provided on the tray 326.

Here, a light-shielding lid 32 is placed on the tray 326.
7 is provided because, for example, when the positive sheet 101 is transparent for OHP use or thin like paper, the time from the developer spreading until the latent image on the negative film 200 is fixed is set on the back side of the positive sheet 101. This is to avoid unnecessary exposure due to the transmitted light since the negative film 200 is exposed by the transmitted light and a good image cannot be obtained. The lid 327 is rotatably and removably engaged with a support shaft 328 fixed to the tray 326, and the tray 326 is rotatable around a shaft provided coaxially with the support shaft 328 on the apparatus main body side. , and are removably engaged.

After the developer has finished spreading, a predetermined timer starts to count the fixing time (approximately 30 to 40 seconds), and displays a prohibition of opening the lid 327 within the fixing time, and a dark box after the fixing time has elapsed. Inside (tray 326 and lid 32
A message indicating that the negative/positive bonded body (the bonded body of the negative film 200 and the positive sheet assembly 100) can be taken out from the dark box according to No. 7 is displayed. Here, when the negative/positive bonded body is taken out from the tray 326, the rear end is detected by the sensor S7. Next, the printer becomes ready for printing. Furthermore, while the developing rollers 325a and 325b are separated, printing operation is prohibited, and negative and
Prevents forgetting to remove positive conjugate.

After the development is completed, the user can obtain an image by peeling off the positive sheet 101 from the negative/positive bonded body. The leader 102, tip mask 104, both side masks 105, and trap mask 106 of the positive sheet assembly 100 shown in FIG. It is adhered to the film 200 side and easily separated by peeling off the positive sheet 101 from the negative/positive bonded body.

As shown in FIG. 1, the length L in the width direction of the pod 103 on the positive sheet assembly 100 is equal to or shorter than the width b of the image area so that it does not break due to pressure contact with rollers etc. during conveyance. It has become. For this reason, after the pod 103 is cleaved at the F portion, a certain distance (distance indicated by E in the figure) is required until the pod 103 is spread to the image area width b. Further, as described above, the deviation J when aligning the negative film 200 and the positive sheet assembly 100 should be shorter than the distance C from the tip of the positive sheet assembly 100 to the cleavage part F of the pod 103, and therefore, as shown in FIG. Distance C' from the tip of the negative film 200 to the tip of the latent image area
should be at least longer than the distance E from the cleavage part of the pod 103 to the tip of the image forming part in FIG.

As mentioned above, in the first embodiment, the problem that the negative film 200 in use is drawn into the negative film cartridge 201 is solved by a very simple and inexpensive means as shown in FIGS. 3 and 4. It can be solved. Therefore, when handling the negative film cartridge 201, the user should avoid applying vibrations,
The negative film cartridge 201 can be easily used without taking extra precautions such as not to accidentally push the leading end of the negative film 200 into the negative film cartridge 201.
