Description

The present invention relates to a film carrier for transporting a film in a longitudinal direction to perform a baking operation.

[Conventional technology]

A film carrier used for printing an image from a negative film onto photographic paper has a recess corresponding to the width of the film to form a film transport path.

The negative film accommodated in the film transporting path is fed in the longitudinal direction and stopped at the printing position so that the image at the printing position is printed on the printing paper.

However, the film to be printed may have a plurality of films connected in series with a splice tape.Since this splice tape is configured to connect both widthwise end portions of the film to each other, the width dimension of the film is It will be substantially increased in part. For this reason, when the film is finely adjusted in the longitudinal direction near the printing position to stop the image position accurately at the printing position, the splice tape portion causes friction with the side wall of the film conveyance path to adjust the fine movement of the film. Cause to interfere.

[Problems to be solved by the invention]

In view of the above facts, the present invention has an object to obtain a film carrier which does not hinder the fine movement adjustment at the printing position of the film even when there is a splice tape.

[Means for solving the problem]

The present invention is a film carrier in which a concave portion corresponding to a film width dimension is formed to serve as a film transport path,
It is characterized in that the width dimension of the recess is enlarged from the vicinity of the baking position to a predetermined position on the downstream side to reduce the frictional resistance when passing through the film connecting portion.

[Action]

Therefore, in the present invention, even when a plurality of films are connected by splice tapes and the width dimension is enlarged, when the image in the vicinity of the splice tapes reaches the printing position, the splice tapes are formed in the film transport path. The splice tape portion is smoothly moved corresponding to the widened portion. Therefore, the frictional resistance between the end portion of the film in the width direction of the film and the side wall of the conveying path is reduced, and the fine movement in the longitudinal direction of the film can be adjusted easily and reliably.

Example of Invention

A film carrier to which the present invention is applied is shown in FIGS.
10 is shown. In this film carrier 10, the arm 14 pivots with respect to the pedestal 12 fixedly installed at the printing position, and the negative film F is moved in the longitudinal direction (direction of arrow A) on the film transport path S to the printing optical axis P. It is possible to send in and sequentially print each image frame.
Further, the negative film F can be moved in the film width direction (the direction of arrow B) and fed into the film transport path S as required.

 The configuration of each component will be described below.

The pedestal 12 is mounted and fixed at a baking position (not shown), and an operator faces the film carrier 10 in the direction of arrow B to perform the baking work. Therefore, the pedestal 12 is provided with a plurality of operation buttons 16 on the side closer to the operator.

A guide 18 is fixed on the upper surface of the central portion of the pedestal 12, and a recess 22 formed on the top surface of the guide 18 constitutes a main part of the film transport path S.

On the other hand, the arm 14 is pivotally supported on the pedestal 12 by the shaft 24, and when the opening 26A formed in the bracket 26 fixed to the tip end is engaged with the latch 28 provided on the pedestal 12, the
As shown in the figure, the concave portion 22 is closed. A compression coil spring 32 is provided on the base 12 in a direction in which the arm 14 is separated from the base 12. In the closed state of the arm 14, the guide surface 48A of the pressing base 48 is pressed against the top surface 18A of the guide base 18,
The guide protrusions 64 of the pressing base 48 enter into the recesses 22 and guide the vicinity of both ends of the negative film F to the running surface of the recesses 22.

As shown in FIG. 5, the latch 28 is attached to the base 12 by the shaft 34.
The release button 36, which is partly exposed on the front surface of the pedestal 12, is pushed toward the optical axis P for printing and the latch 28
Is separated from the opening 26A against the urging force of the return spring 38, whereby the arm 14 can be opened (in the direction of arrow C). The release button 36 is fixed to one end of the slide plate 42, and is screwed into the long hole 42A formed in the slide plate 42.
The 4 penetrates so that it can move along the pedestal 12, and this screw 44 is screwed to the pedestal 12. One end of the slide plate 42 corresponds to the latch 28 so that the operating force applied to the release button 36 is transmitted to the latch 28.

A pressing plate 46 is coaxially supported on the arm 14 coaxially. The pressing plate 46 is sized to enter the arm 14. The pressing plate 46 is urged by a compression coil spring 54 provided on the top surface of the pedestal 12 in the direction above the pedestal 12, that is, in the direction of entering the arm 14. Also this pressing plate
Solenoid 56 is fixed to 46.
One end of a movable shaft 58 penetrating 56 is fixed to the arm 14. Further, the other end of the movable shaft 58 has a suction plate 62, and when the solenoid 56 is energized, the suction plate 62 becomes a solenoid.
Adsorbed to 56.

Therefore, the solenoid 56 is urged together with the pressing plate 46 from the state of FIG. 5 to the state of FIG. 7, that is, in the direction of approaching the pedestal 12 away from the arm 14 against the urging force of the compression coil spring 54. It is supposed to be done.

A baking opening 12A is formed in the pedestal 12 with the baking optical axis P as an axis, and a similar baking opening 48B is formed in the pressing base 48, the pressing plate 46 and the arm 14. Corresponding to the baking opening 48B, a pair of pressing plates 66 are attached to the pressing table 48 so as to press both widthwise ends of the negative film F toward the bottom surface of the recess 22 during baking. As shown in FIG. 5 (B), these pressing plates 66 are connected to each other by a connecting piece 66A, and pins 51 standing from the pressing base 48 are penetrated therethrough, and compression coil springs are attached to these pins 51. When the pressing table 48 is closed by the urging force in the direction in which the pressing table 48 projects from the pressing table 48 and enters the film conveying path S, the concave portion is formed by the urging force of the compression coil spring 67.
The both ends of the negative film F in the width direction are clamped to the bottom surface of 22 with a weak force.

Further, the pressing plate 46 is penetrated by four pins 69 at its tip end, and the tip end of the compression coil spring 70 is urged in the direction of being pressed by the pressing plate 66. These pins 69 transmit the biasing force of the compression coil spring 70 to the pressing plate 66 when the pressing plate 66 is lowered by the exciting force of the solenoid 56 as shown in FIG.
Is strongly pressed against the bottom surface of the concave portion 22 to fix both end portions in the width direction of the negative film F.

On the pedestal 12, rectangular openings 22A and 22B are formed on the bottom surface of the recess 22 corresponding to the upstream side and the downstream side of the baking opening 12A.
A part of the feed rollers 68 and 72 axially supported inside the part 18 projects to the film transport path S through them. These feed rollers 68 and 72 are adapted to be projected into the recess 22 by the same amount as the bottom surface of the recess 22 or by a slight amount.

On the other hand, pressing rollers 78 and 82 are also axially supported inside the pressing base 48, and are pressed against the outer circumferences of the feed rollers 68 and 72 when the arm 14 is closed. These pressure rollers 78, 82
Is subjected to an urging force of a compression coil spring 86 (not shown) to be pressed against the feed rollers 68 and 72 to generate an urging force for sandwiching both ends of the negative film F in the width direction.

Similarly, on the upstream side of the feed roller 72, short-shaped openings 22C are provided in the vicinity of both ends in the film width direction.
88 is exposed. Similarly, a pressing roller 92 that is pressed against these feed rollers 88 is pivotally supported on the pressing base 48. Further, these feed rollers 68, 72, 88 are adapted to rotate within the base 12 by receiving a motor driving force (not shown).

Between the feed roller 68 and the feed roller 88, a protective glass 93 and a light source 94 (see FIG. 3) are provided in the width direction of the negative film F corresponding to the bar codes B displayed near both ends in the width direction of the negative film F. Corresponding to the vicinity of both ends, it is embedded in the bottom surface of the recess 22. A pair of sensors 96 for detecting the bar code B with the negative film F sandwiched between the light source 94 and the light source 94 are fixed to the pressing base 48 at intervals WS. Further, guide blocks 98 and 102, which are first guide portions, are arranged on the upstream side and the downstream side of these sensors 96 so as to correspond to both end portions in the width direction of the negative film F. That is, the distance between the pair of guide blocks 98 and the guide block 102.
The interval WG between them is made slightly smaller than the width dimension WF of the negative film F, and as a result, as shown in FIG. 3 (A), the cross section of the negative film F in the width direction is conveyed. It is designed to produce a curled widthwise curl.

Further, in the negative film F having the widthwise curl, the notch escape portion 104 corresponding to the center portion of the film is formed in the concave portion 22 and the pressing base 48 so that the central portion in the width direction does not contact the concave portion 22 and the pressing base 48. 106 are provided. Further, as shown in FIG. 3, the bottom surface of the concave portion 22 and the tip end portion of the guide protrusion 64 are inclined by an angle θ with respect to a plane perpendicular to the optical axis P, corresponding to the vicinity of both ends in the width direction of the negative film F. In order to guide both ends of the negative film F, inclined surfaces 104A and 106A which are parallel to each other when the arm 14 is closed constitute a second guide portion.

As a result, the negative film F is forcibly imparted with a curl in the width direction as shown in FIG. 3, and the intermediate portion in the width direction, which is the image forming surface, is not in contact with the guide surface, so that the image surface is scratched. There is no such thing. Further, the photo sensor 96A and the light source 94 of the sensor 96 for reading the bar code B are read.
Can reliably correspond to the barcode B. That is, the bar code B is formed in advance at a predetermined position from the end face in the width direction of the negative film F, so that the sensor 96 does not follow the film width end but the film width end follows the guide blocks 98 and 102. Becomes the light source 9
4. The bar code B can be read accurately by arranging the sensor 96 at a predetermined relative position with the facing surfaces of the guide blocks 98 and 102.

FIG. 4 shows a structure for arranging the guide blocks 98 and 102 at precise intervals and appropriately arranging the relative position between the sensor 96 and the guide blocks 98 and 102.

Positioning block 1 is attached to the press base 48 by the mounting screw 112.
14 is fixed. Guide blocks 98 and 102, which are integrally connected to each other on both sides 114A of the positioning block 114 in advance through a connecting portion 116, are fixed by screws 118, and a sensor 96 is provided in a recess 114B formed in the positioning block 114. Are fixed with screws 122.

For this reason, by accurately forming the distance between the side surfaces 114A and WG and the distance between the concave portions 114B in WS, these can be surely fixed by simply fixing the sensor 96 and the guide blocks 98 and 102 with screws. It will be installed at intervals. The guide blocks 98 and 102 are formed with arc portions 98A and 102A for accurately guiding the edges of the negative film F, and the negative film F is not curled in the width direction near the upstream end of the film transport path S. Narrow guide block 98,
It smoothly guides to the space between 102 to facilitate curling in the width direction.

As an example, the width dimension is 35 mm and the dimensional tolerance is +0 mm and -0.1 mm.
When transporting a 35mm film, set the spacing WG to 34.7mm ± 0.
It can be 1 mm. If this dimension WG is set to 34.5 mm or less, it becomes impossible to convey when the width dimension of the negative film F is substantially increased by the splice SP for connecting a plurality of negative films F as shown in FIG. .

As shown in FIG. 1, a deep groove 124 is formed in the recess 22 on the upstream side and the downstream side of the light source 94 so that the tips of the guide blocks 98 and 102 enter when the arm 14 is closed.

A pair of positioning plates 134 are fixed to the top surface 18A of the guide stand by screws 132. The circular holes 136 formed in the positioning plates 134 are for inserting the positioning pins 138 protruding from the pressing base 4.

The positioning plate 134 and the positioning pin 138 are provided to accurately attach the pressing base 48 to the guide base 18 at a predetermined relative position. That is, since the pressing base 48 is pivotally supported on the pedestal 12 via the pressing plate 46 and the support shaft 24, it is difficult to accurately position the concave 22 of the guide base 18, and the pressing plate 46 with respect to the pedestal 12. The relative position may shift by opening and closing multiple times, which causes the negative film F
It is conceivable that the accurate conveyance of the bar code B becomes impossible and the bar code B cannot be detected by the sensor 96. Therefore, at the time of assembly, the screw 52 is lightly screwed into the pressing plate 46 so that the pressing base 48 is temporarily fixed to the pressing plate 46, and the pressing base 48 is fixed to the pressing plate 46.
As shown in the drawing, the guide protrusion 64 of the pressing base 48 and the concave portion 22 are accurately made to correspond in a state where the pressing base 48 is made to correspond to the concave portion 22 of the guide base 18, and thereafter the arm 14 is moved as shown in FIG. Open and screw the screw 52 firmly together, and position plate
Fix 134 with screws 132. By this positioning work, the pressing base 48 is accurately positioned and fixed to the guide base 18, and even when the supporting position of the pressing base 48 is slightly different due to the deformation of each part due to the multiple use, the pressing base 48 is changed as shown in FIGS. By aligning the arm 14 and the pressing base 48 with the guide base 18 as shown in FIG. 3, the positioning pin 138 is inserted into the circular hole 136, so that reliable positioning can be performed.

When the arm 14 is opened to the state shown in FIG. 8 by operating the release button 36, the hook 144 pivotally supported by the pin 142 on the pedestal 12 is engaged with the side surface of the pressing base 48 by the urging force of the compression coil spring 146. In addition, the opening angle of the pressing base 48 is limited. Therefore, if the worker grips the tip of the hook 144 and rotates it in the clockwise direction in FIG. 8 against the biasing force of the compression coil spring 146, the hook 144 is disengaged from the pressing base 48 and the pressing plate 46 and the arm 14 are removed. As shown in Figs. 1 and 10, it can be opened greatly. An intermediate portion of the hook 144 is inserted into a short opening 46A formed in the pressing plate 46 and a short opening 14A formed in the arm 14. Further, the tip end of the compression coil spring 32 is in contact with the arm 14 through a circular hole 46B formed in the pressing plate 46.

As shown in FIGS. 2, 5, and 6, a pair of notch detection pins 162 are provided slightly upstream of the optical axis P so as to correspond to both ends of the negative film F in the width direction. The notch detecting pin 162 has a substantially cylindrical shape as shown in FIG.
The ends are hemispherical. Further, the support pin 164 is inserted into the notch detection pin 162 from the large-diameter side end portion, so that the notch detection pin 162 can freely rotate around the support pin 164. Further, the notch detecting pin 162 has a large-diameter side end portion supported by the enlarged diameter portion 164A of the support pin 164. A base portion 164B of the support pin 164 is pivotally supported on a middle portion of the swing plate 166 in the longitudinal direction.

A pin 168 protruding from one end of the swing plate 166 is pivotally supported on the guide base 18, and a limit switch 172 corresponds to the tip end thereof. Further, these swing plates 166 are designed so that the notch detecting pins 162 are pressed in the negative film F direction by a torsion coil spring 174.

Notches 22D are formed on the side surface and the bottom surface of the concave portion 22 of the guide base 18, so that the notch detection pin 162 projects toward the film transport path S and is pressed against the side surface of the negative film F. As shown in FIG. 9, a thin portion 18B is formed on the guide base 18 by the notch portion 22D so as to cover the notch detecting pin 162 and prevent the notch detecting pin 162 from being pulled out from the support pin 164. Therefore, the first
The negative film F is moved in the direction of arrow B in FIG.
Even when the negative film F is inserted into the concave portion 22, the end portion in the width direction of the negative film F can be dropped into the concave portion 22 without interfering with the notch detecting pin 162.

Further, when the negative film F is inserted into the recess 22 in the direction of arrow B in the state of FIG. 8 and the pressing base 48 approaches the pedestal 12 in the state of FIG. 5, both ends of the negative film F in the width direction are approached. Even if the negative film F remains on the notch detecting pin 162 or the peripheral surface as shown in FIG. 8, the notch detecting pin 162 has a spherical upper end. Therefore, the negative film F receiving the pressing force of the pressing table 48 twists the notch detection pin 162 and the coil spring 174.
The negative film F can be easily moved in the direction away from the widthwise end of the negative film F against the urging force of the negative film F, and the widthwise end of the negative film F is located between the pressing base 48 and the notch detection pin 162. There is no problem of pinching and bending.

Since these notch detecting pins 162 are arranged on the upstream side by a slight amount from the optical axis P, they enter the notch NT formed at the center of the image surface of the negative film F to detect the image surface, This image plane can be accurately stopped at the optical axis P.

As shown in FIG. 2, a widened portion 182 is formed in a portion slightly downstream of the notch detection pin 162, in which the interval between the facing surfaces of the recess 22 is enlarged. The widened portion 182 is formed over the range of the length L toward the downstream side of the film transport path S, and the splice tape SP is connected to the connection portion of the negative film F.
Even if a negative film is provided, the negative film F can be easily
Can be transported. That is, when the splice tape NT is located in this range, the resistance to the operation of finely adjusting the image surface in the transport direction and accurately arranging it on the optical axis P becomes large, but the resistance is increased by providing the widening portion 182. Smaller size makes fine movement adjustment easier.

Further, since the pressing plates 66 correspond to both ends in the width direction of the negative film F arranged on the optical axis P to press the negative film F to the bottom surface of the recess 22, the curl of the negative film F is eliminated. Although the tip of the negative film F does not catch on the end surface of the baking opening 12A, the width of the recess 22 is further expanded by the widening portion 182, so that the splice tape is formed.
Even if there is a connection part of the negative film F by SP, the curl of the negative film F can be eliminated.

Since the thickness of the widened portion 182 is 0.1 mm or less, the splice tape SP is preferably enlarged by 0.2 mm or more on one side of the film as compared with other portions. If the width is 0.1 mm, the amount of widening is insufficient and the resistance of the negative film F to conveyance is great. Also,
The length L, which is the range in which the widened portion 182 is formed, has an upstream end downstream of the center of the notch detection pin 162 and a downstream end between the end of the printing opening 12A and the feed roller 72. It is preferable. That is, if the downstream end of the widened portion 182 is located upstream of the end of the baking opening 12A, the tip of the negative film F may interfere with the edge of the baking opening 12A. When the driving force is applied at 72 and 82, the attitude of the negative film is unstable and the film is likely to meander.

A film carrier 188 is attached at a position on the downstream side of the film transport path S, which the pressing table 48 does not support. This film carrier 188 reverses the negative film F conveyed past the optical axis P in the direction of arrow A so as to turn it over, and at the same time in the plane state shown in FIG.
The negative film F is conveyed in the direction of 45 ° and is sent back toward the worker in the direction of arrow D.

As shown in FIGS. 11 to 13, this film carrier
Reference numeral 188 denotes a pair of screws 19 projecting to the bottom surface on the downstream side of the guide 18.
The short mounting portion 202 is locked to the guide base 18 by the reference numerals 2 and 194. From this mounting part 202 to the lower guide plate 196
Also, the upper guide plate 198 arranged in the recess 22 of the guide base 18 is extended. The side surface 202A of the mounting portion 202 is formed with a notch 204 for receiving the screw 192.
A notch 206 is formed on the side surface 202B adjacent to A and a screw 194 is formed.
It is for acceptance of. The entrance of the notch 204 is wide so that the screw 192 will come out of the notch 204 when the mounting part 202 is rotated around the screw 194. A circular recess 204A is formed. The slit 20 is formed on the portion where the concave portion 204A is formed.
It is easily elastically deformed by 4, and the mounting portion 202 is locked to the screw 192 of the guide 18 by this elasticity.

The vicinity of the side surface 202C on the opposite side of the side surface 202A is made thick in the mounting portion 202, and the lower guide plate 196 is integrally projected. The lower guide plate 196 is arranged in parallel with the downstream side of the upper guide plate 198 to form a groove-shaped guide portion 208 on one side in the width direction of the negative film F, and at the same time as the lower guide plate 196 and the upper guide plate 196. The widthwise end portions of the guide plate 198 are connected to each other by the connecting portion 212 so as to prevent the widthwise end portion of the negative film F from coming off. The guide portion 208 has a widened portion 208A on the opening side of the lower guide plate 196 and the upper guide plate 198 and a narrowed portion 2 on the bottom of the groove.
It is said to be 08B. Therefore, the narrow portion 208B is the negative film F.
The widened portion 208A is provided for contact guidance with the side portion of the negative film F, and a gap is provided between the widened portion 208A and the central portion in the width direction of the negative film F, thereby preventing damage to the image.

The upper guide plate 198 extends to the upstream side in the transport direction of the negative film F and enters the recess 22, and forms a guide portion 214 with the bottom surface of the recess 22. Similar to the guide portion 208, the guide portion 214 has a width dimension of about 1/2 of the negative film width dimension so as to correspond to only one side of the negative film F. A slope 198A is formed at the upstream end of the upper guide plate 198, and a slope 64 formed at the downstream end of the guide protrusion 64.
Corresponding to A, and as shown in FIG. 12, the upper guide plate 198 is conveyed in the direction of arrow A by being arranged farther from the bottom surface of the concave portion 22 than the guide protrusion 64 in the conveying state of the negative film F. The negative film F can be smoothly guided between the upper guide plate 198 and the recess 22.

As shown in FIGS. 12 and 13, the narrow portion 208B of the guide portion 208 communicates with the base recess 22 so that the negative film F can be smoothly received from the recess 22.

As described above, the film carrier 188 of this embodiment has an arrow A.
Even when the negative film F conveyed in the direction past the optical axis P is curled in the longitudinal direction, this negative film F
Can be reliably sent in the direction of the arrow C toward the operator, and the curled negative film F can be carelessly moved to the optical axis P.
It does not move in the direction. Further, since the film carrier 188 corresponds to only one side of the negative film F, the work of loading the negative film F in the direction of arrow B onto the optical axis P is not limited to the case of inserting the negative film F in the direction of arrow A. Does not hinder.

The film carrier 188 sends out the negative film F in the direction of arrow D, and about 90 degrees around the direction of arrow D.
It may be delivered in the range of °. Further, since the film carrier 188 can be easily removed by rotating the mounting portion 202 around the screw 194, it can be easily removed when it interferes with the work such as when continuously feeding a long film. Can be removed. In this embodiment, the upper guide plate 198 of the film carrier 188 is about 1/2 of the film width dimension, but in the present invention, it is preferably 1/3 or less of the film width dimension. Also lower guide plate 1
96 is a widening extension portion 19 as shown in phantom lines in FIGS.
6A may be extended to cover the entire area of the negative film F.

 Next, the operation of this embodiment will be described.

When the operator brings the arm 14 closer to the pedestal 12 from the state shown in FIG. 1, the hook 144 engages with the pressing base 48 and the state shown in FIG. In this state, the negative film F can be inserted in the direction of arrow B in FIGS. The negative film F inserted in the direction of the arrow B is accommodated in the recess 22. At this time, the notch detecting pin 162 is covered with the thin portion 18B, so that the widthwise end face of the negative film F is not covered. The notch detection pin 162 does not hinder the movement, and can be inserted smoothly.

Also, when the pressing base 48 is closed with the end face of the negative film F riding on the notch detecting pin 162 exposed to the recess 22 through the notch 22D, the notch detecting pin 16
Since the upper end surface of 2 has a spherical shape, the negative film F separates the notch detection pins 162 from each other by the pushing-down operation of the pressing base 48 and the riding state is eliminated, so that the negative film F is not scratched or damaged. There is no problem such as breakage. Further, since the upper guide plate 198 of the film carrier 188 is arranged only on the far side of the film transport path S far from the operator, the negative film F can be easily inserted into the film transport path S. In this state, since the guide blocks 98 and 102 are not inserted into the deep groove 124 of the pedestal 18, the negative film F is in the recess 22 wider than its width dimension, and no curl in the width direction is generated.

Further, when the pressing base 48 is pushed down from the state shown in FIG.
In the state shown in the figure, the latch 28 engages with the opening 26A. In this state, the upper part of the recess 22 is closed by the pressing base 48, so that the next negative film F can be inserted into the film transport path S from the direction of arrow A in FIG. In the vicinity of the printing optical axis P, the pressing plate 66 is lightly pressed to the bottom surface of the recess 22 by the urging force of the compression coil spring 67, but this urging force is weak, so that the conveyance of the negative film F sent in the direction of arrow A is prevented. There is no.

In this state, the guide block 9 is inserted into the deep groove 124 of the pedestal 18.
Since 8 and 102 are inserted, the negative film F accommodated in the recess 22 in the direction of arrow B is moved in the width direction by the insertion operation of the guide blocks 98 and 102 into the deep groove 124. Then, the width end of the film is accurately inserted between the guide blocks 98 and 201 to generate a curl in the width direction as shown in FIG. 3 (A). Further, when the negative film F is inserted in the direction of arrow A after the guide projection 64 is inserted into the recess 22 as shown in FIG. 5, the longitudinal end of the negative film F is guided to the circular arc portions 98A and 102A. Then, it is inserted between the guide blocks 98 and 102, and a curl in the width direction similarly occurs.

The negative film F is rotated by the rotation of the feed rollers 68, 72, 88.
Is conveyed by an arbitrary amount, and a desired image frame is arranged on the optical axis P. In this case, by reading the bar code B of the negative film F, an arbitrary image frame can be stopped on the optical axis P, or the printing condition of the image frame stopped on the optical axis P can be corrected. Here, the negative film F is a guide block 98,
Since the width direction curls are forcibly generated by the pressing force in the direction in which the width direction both ends approach each other by 102, the front and back surfaces of the width direction both ends are inclined as shown in FIG.
Since it is held by the 4A and 106A, the barcode B surely corresponds to the light source 94 and the sensor 96, and is accurately read by the sensor 96. Further, the image portion in the widthwise intermediate portion of the negative film F in the conveyed state is not in contact with the guide surface by the notch escape portions 104 and 106, so that the image is not scratched.

Further, as shown in FIG. 2, since the notch detecting pin 162 is urged in the direction in which the notch detecting pin 162 enters into the notch NT of the negative film F by the urging force of the torsion coil spring 174, before the center of the image frame reaches the optical axis P. , The notch NT of the film is detected by the limit switch 172, and the feed amount of the feed rollers 68, 72, 88 is controlled thereafter, so that the image surface is surely aligned with the optical axis P and stopped.

In particular, since the widened portion 182 is formed on the downstream side of the optical axis P, it is accurate even when the negative film F is automatically stopped at the optical axis P position or when the moving amount is corrected by manual feeding. Positioning is possible. That is, negative film F
If the splice tape SP is present at the connection part of the, the image frame immediately after the splice tape SP is attached
When stopping upward, the frictional force between the splice tape SP and the side surface of the recessed portion 22 hinders fine adjustment of conveyance, but this widened portion 182 causes a substantial width dimension increased portion by the splice tape SP. Also guides smoothly so that the optical axis P
The image can be stopped at the top.

At the time of printing, the attraction plate 62 is attracted by the excitation of the solenoid 56, so that the pressing plate 46 is recessed as shown in FIG.
When pressed inward, the pressing plate 66 is recessed at both ends in the width direction of the negative film F on the optical axis P by the strong biasing force of the compression coil spring 70.
Press on the bottom of 22. Here, the image is printed on a printing paper (not shown) with a printing destination from a light source (not shown).

During the pressing operation of the pressing plate 46 at the time of printing, since the negative film F is already arranged in a flat plate shape on the bottom surface of the concave portion 22, the negative film F is not scratched or bent.

When the printing is finished, the power supply to the solenoid 56 is stopped,
The pressing plate 46 is raised to the state shown in FIG. 5 and the pressing force by the pressing plate 66 is weakened, so that the negative film F is again fed by the feed roller 6.
It is sent out in the direction of arrow A by the driving force of 8, 72.
For this reason, the negative film F enters the film carrier 188, is inverted and passed through between the lower guide plate 196 and the upper guide plate 198, and is turned in the direction of arrow D to the operator's hand. The film F does not inadvertently return to the vicinity of the optical axis P due to the curl in the longitudinal direction,
The operator can quickly take out the negative film F and prevent scratches. The inside of this film carrier 188 is a negative film F
When the guide portion 208 passes, the narrow width portion 208B of the guide portion 208 comes into contact with the film edge, so that the intermediate portion in the width direction of the film is separated from the widening portion 208A, and the scratches on the image forming surface of the negative film F are prevented. ing.

In the above embodiment, the notches NT are formed at both ends of the negative film F in the width direction.
The NT can be applied even if it is provided only on one end of the negative film F in the width direction.

〔The invention's effect〕

Since the present invention has the above-described structure, it has an excellent effect that fine adjustment can be easily and surely performed even with a film provided with a splice tape.
