Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a film carrier used for printing an image on a film onto a light-sensitive material.

[Prior art]

Generally, a film carrier (negative carrier) is used when printing an image onto photographic paper after developing a negative film.

The negative carrier is provided with a negative film transport path, and the negative film is guided and moved along this negative film transport path. An upper mask and a lower mask are disposed in the intermediate portion of the negative film conveyance path in the negative film conveyance direction, and an opening for one full-size image frame is provided. This opening is the irradiation position of the light beam from the printing light source during loading into the printing device. Therefore, the image frame of the negative film positioned in this opening is printed.

The negative film can be moved along the negative film conveyance path by separating the upper mask and the lower mask, and the image frames are successively positioned in the opening, allowing continuous printing processing.

By the way, negative film is made by transporting multiple long negative films (one roll of film) connected to the negative carrier one after another with splice tape, but all the image frames are shot at full size. However, there may be some films shot in half size. Here, since the ratio of the vertical dimension and the horizontal dimension is opposite between a full-size image frame and a half-size image frame, the photosensitive material loaded in the printing device (
Printing cannot be done with the width of photographic paper (photographic paper).

For this reason, conventionally, the negative carrier is once removed from the printing device, rotated by 90 degrees, and then loaded into the printing device again.

[Problem to be Solved by the Invention] However, it is very difficult to attach and detach the negative carrier from the printing device each time a full-size image frame and a half-size image frame are switched, and the negative film When loaded in a negative carrier, there is a risk that the image frames of the negative film may be damaged.

The present invention has been made in consideration of the above-mentioned facts, and an object of the present invention is to provide a film carrier that can change the direction of film transport in accordance with the size of image frames while the film carrier is loaded into a printing device.

[Means to solve the problem]

The film carrier according to the present invention transports the film and positions successive image frames on the film to a predetermined printing position on the photosensitive material when printing an image recorded on the film by a printing device onto a photosensitive material. The film carrier is provided with a film carrier body having a film transport path formed therein, a support plate that supports the film carrier body so as to be relatively rotatable about an optical axis, and a film carrier provided between the support plate and the printing device. positioning means for positioning the supporting plate at a predetermined position of the printing device; and a first positioning means provided between the film carrier body and the supporting plate for aligning the direction of film transport by the film transport path with the direction of transport of the photosensitive material. and a locking means for locking at a second position orthogonal to the first position, and a locking state by the locking means when the film carrier main body is rotated with a predetermined rotational force. and a canceling means for canceling the cancellation.

[Effect]

According to the present invention, the film carrier body is loaded into the printing device via the support plate, and the support plate and the film carrier body can be rotated relative to each other. The direction in which the film is transported by the transport path can be changed.

Further, since the locking means can lock the film at the first position where the film transport direction coincides with the transport direction of the photosensitive material and at the second position where the film transport direction is perpendicular to the transport direction of the photosensitive material,
For example, there is no need to remove and attach the film carrier from the printing device each time an image frame recorded in full size (standard size) and an image frame recorded in half size (smaller than the standard size) is switched, which improves work efficiency. will improve.

Furthermore, the locked state by the locking means can be released by rotating the film carrier main body with a predetermined rotational force, which facilitates the operation.

〔Example〕

FIG. 1 shows a negative carrier 10 according to this embodiment. This negative carrier IO is constructed with a pedestal 12 and an opening/closing cover 14 as main parts.

(Configuration of pedestal 12) A negative film transport path 16 is formed in the pedestal 12. The negative film transport path 16 has guide surfaces 18 at both widthwise end portions of its bottom surface that contact and guide a portion of the negative film 17 other than the image, and a recess 20 is formed in the widthwise intermediate portion. This prevents the image surface of the negative film 17 from coming into contact with the negative film transport path 16 when the negative film 17 moves on the negative film transport path. A printing opening 22 is provided in the longitudinal center of the negative film transport path 16, and serves as an opening for irradiating light from a light source provided in a photographic printing apparatus (not shown). The size of the printing opening 22 is the same as the full size image frame 17A of the negative film 17. In addition,
The recess 20 is not formed around the printing opening 22 to block light, and the printing light of only the -image frame 17A can be transmitted through a pressure bonding plate 24, which will be described later.

As shown in FIG. 6, on the guide surface 18 of the negative film transport path 16, both widthwise ends of the negative film transport path 16,
That is, a notch 28 is formed at the corner with the negative film transport path side 26, and the corner formed by the side 26 and the guide surface 18 is an acute angle (less than 90°). This corner is the part that the widthwise end of the negative film 170 comes into contact with, and by providing the slight notch 28 in the guide surface 18 in this way, it is possible to absorb slight errors in the width dimension of the negative film 170. can. Therefore, when the negative film 17 is transported along the negative film transport path 16, the negative film 17 can be guided smoothly without being caught or the like. In addition,
As shown in FIG. 6, the depth of the notch 28 is preferably such that the widthwise end of the negative film 17 having a wall thickness of 0.022 ff1ffl does not dig into the corner.

Further, the guide surface 18 and the recess 20 are connected by an inclined slope with respect to the guide surface 18, and all corners are rounded to prevent scratches on the image surface when the negative film 17 is moved. There is.

As shown in FIG. 2, the negative film transport path 16 includes:
Conveying rollers 30, 32, and 34 are disposed on the upstream side (left side in FIG. 2) and downstream side (right side in FIG. 2) of the printing opening 22, corresponding to the back surface (lower surface) of the negative film 17. The conveyance rollers 30, 32, and 34 are each disposed within a rectangular hole 36 provided in the negative film conveyance path 16, and the tangent line thereof is equal to or slightly protrudes from the guide surface 18, and each rotation shaft 38 is arranged in a rectangular hole 36 provided in the negative film conveyance path 16. It is located below the road. Both axial ends of the rotating shaft 38 have a small diameter, and the base thereof is supported by the base 12 via a bearing (not shown). A pulley 40 is fixed to one end of the rotating shaft 38, and a timing belt 42, 44 is passed through the pulley 40, respectively.

Further, a timing belt 52 is passed between a pulley 40 of the conveying roller 34 on the downstream side of the burning opening 22 and a pulley 50 fixed to a rotating shaft 48 of a motor 46 . As a result, each conveyance roller 30 is driven by the driving force of the motor 46.
．． 32 and 34 are designed to be driven in the same rotational direction and at the same rotational speed.

A pair of partition plates 54 whose opening area can be changed are arranged on the lower surface side of the baking opening 22. Partition plate 54
are located on the same plane and parallel to each other,
It is connected to an operation section 58 disposed in the center of the operation panel 56. The operation panel 56 is disposed below the base 12 in FIG. 2, and has a recess 60 formed in its center, and the partition plate 54 is slidable along the bottom surface of the recess 60.

Both ends of the operating section 58 are fixed to the partition plate 54 via screws (not shown). The operating portion 58 is projected above the operating surface of the operating panel 56, and when the operator grasps this projected portion and moves it in the direction of the arrow in FIG.
The partition plate 54 can be moved into and out of the baking opening 22.

Here, when the partition plate 54 protrudes into the printing opening 22, both ends of the printing opening 22 are blocked from light, and the remaining opening area is a half-sized image frame of the negative film 17 (half of the image frame 17A). It is assumed that the size is the same as that of

That is, when the operating section 58 is pulled toward the front of the page as shown in FIG. 1 (first position), it is adapted to the full-size image frame 17A, and as shown in FIG.
When the operation section 58 is pushed to the back (second position), it is adapted to a half-size image frame. The longitudinal direction of this half-size image frame is perpendicular to the longitudinal direction of the standard-size image frame 17A.

Note that a circular hole is provided in the bottom of the recess 60 of the operation panel 56, and a compression coil spring and a ball (both not shown) are accommodated therein, and the partition plate 54 has an operation section as shown in FIG. When 58 is located in the first position, the corresponding circular hole 6
2, and a circular hole 64 that corresponds when the operating section 58 is located at the second position. The circular holes 62 and 64 each have a slightly smaller diameter than the balls, thereby producing a click feeling at the first and second positions of the operating portion 58, thereby facilitating the operation of switching between full-size and half-size apertures. It is certain.

Further, as shown in FIG. 2, the concave portion 60 of the operation panel 56 is provided with a rectangular hole 66, a limit switch 68 is disposed, and a contactor 70 thereof is protruded. This contact 70 interferes with the operating section 58 when the operating section 58 is located at the first position, and is pushed into the rectangular hole 66 to switch the contact of the limit switch 68. Thereby, the operating position of the operating section 58 can be detected when the limit switch 68 is in a conductive state.

The operation panel 56 is provided with operation buttons 72 for manually adjusting the negative film 17 positioned on the negative film transport path 16 and for advancing frame by frame.

Here, the upper surface of the operation panel 56 and the upper surface of the pedestal 12 are flush with each other, so that the piece negatives cut into every 6 frames can be smoothly inserted into the negative film transport path 16 from the front side of the paper in the second drawing. It is now possible to do so.

The bottom surface of the recess 60 of the operation panel 56 is further recessed at the center in the width direction, and a latch 74 is housed therein. latch 74
As shown in Fig. 5, it is bent in an abbreviated shape,
Its bent portion is supported by the pedestal 12 via a shaft 76, and a substantially horizontal piece (release operation portion 78) extends to the side of the operation panel 56 (on the near side of the paper in FIG. 2) and is erected. A piece (
A latch portion 80) protrudes from the upper surface of the pedestal 12.

A compression coil spring 8 is provided between the release operation section 78 and the pedestal 12.
1 is attached, one end of which is latched to the latch 74, and the other end of which is latched to the base 12. As a result, the launch 74 is moved to the fifth position by the biasing force of the compression coil spring 81.
It is designed to be rotated clockwise in the figure. Note that this amount of rotational movement is limited because a portion of the release operation section 78 comes into contact with the operation section 58.

Here, by pushing down the release operation part 78 of the latch 74 against the biasing force of the torsion coil spring, the latch 74
is rotated counterclockwise in FIG. 5 about the shaft 76, so that the latch portion 80 can be moved. The latch portion 80 corresponds to a hook 82 attached to the opening/closing cover 14, which will be described later. By engaging the hook 82 with the latch portion 80, the opening/closing cover 14 can be held in the closed state. (See Figure 3). Note that the negative film transport path 16 of the pedestal 12
A rectangular hole 83 is provided near the rectangular hole 83, and a limit switch 85 is accommodated within this rectangular hole 83. The contact 87 of the limit switch 85 protrudes from the top surface of the pedestal.
When the opening/closing cover 14 is closed, it is pushed into the rectangular hole 83 and the contact of the limit switch 85 is switched. That is, the open/close state of the open/close cover 14 can be detected by the conduction state of the limit switch 85.

As shown in FIG. 2, the negative film transport path 16 includes:
A pair of elongated holes 84 and 86 are provided across the negative film transport path so that they are positioned slightly upstream of the optical axis P when mounted on the pedestal 12. As shown in FIG. 7, the longitudinal direction of these long holes 84 and 86 is the width direction of the negative film 17 placed in the negative film transport path 16. Notch detection pins 88 are accommodated in the elongated holes 84 and 86, respectively. The notch detection pins 88 are fixed to the intermediate portions of the levers 90, respectively.
0 is pivotally supported by the base 12 via a pin 92. The lever 90 is biased by a torsion coil spring (not shown) so that the notch detection pin 88 is disposed at one end of the elongated hole 84, 86 located on the negative film transport path. Further, a striker 94 is formed at the other end of the lever 90, and the striker 94 passes between the light emitting part and the light receiving part of the photosensor 96 attached to the pedestal 12 in accordance with the rotation of the lever 900. ing.

Here, the negative film 17 is placed in the negative film transport path 16, and the notch detection bin 88 and the negative film 17
Notch 17B (
(see FIG. 1), the notch detection pin 88 is pressed by the widthwise end of the negative film 17, and the lever 90 resists the biasing force of the torsion coil spring to open the notch 92.
The striker 94 is rotated around , so that the striker 94 retracts the light beam from the light emitting part of the photosensor 96 to the light receiving part without blocking it. Also, negative film 170
When the notch 17B and the notch detection pin 88 are matched,
The notch detection pin 88 enters into the notch 17B by the biasing force of the torsion coil spring, and as a result, the striker 94 blocks the light beam from the light projecting section to the light receiving section. That is, the movement of the notch detection pin 88 can be detected by the output of the photosensor 96.

By the way, the notch 17B is formed in a pre-processing process by a notch puncher (not shown) so as to correspond to the longitudinal center of the image if the image is suitable for printing. The notch 17B is inserted into the hole to detect the presence or absence of the notch 17B, and then exposure is performed. Since this notch detection is performed slightly upstream of the optical axis P, which is the film stop position, whether or not the image can be printed is determined before the image is aligned with the optical axis P.

Therefore, after the notch 17B is detected by the notch detection pin 88, the negative film 17 is stopped and positioned after the negative film 17 is further transported by a certain amount, so there is no need to abruptly stop the transport at the same time as the notch is detected. ,
This enables high-speed conveyance. Further, the deviation between the notch detection bin 88 and the optical axis position in the film transport direction is made larger than the maximum error of the notch 17B formed on the negative film 17 in the film longitudinal direction. Therefore, the notch 17B is always detected before the optical axis P, and there is no need to reverse feed the negative film 17 after the notch is detected.

(Structure of Openable/Closeable Cover 14) As shown in FIG.
2, and can be opened and closed with respect to the base 12 around this bar 102. A hook 8 corresponding to the latch portion 80 is provided on the opposite side of the cover body 100 to the side pivotally supported by the bar 102 (the upper side in FIG. 1).
2 is fixed with screws 104. As a result, when the open/close cover 14 is rotated toward the base 12 around the bar 102, the hook 82 is engaged with the latch portion 80, and the closed state is maintained.

A through hole 106 corresponding to the burning opening 22 is provided at the bottom of the cover body 100.

Further, an upper guide base 108 is attached to the cover body 100 in a closed state at a position corresponding to the negative film transport path 16. The upper guide base 108 is arranged in the width direction (
A leg plate 11O is erected in the vertical direction in FIG. 1), and the leg plate 110 comes into contact with the upper surface of the pedestal 12 when the cover body 100 is closed. A negative film guide wall 112 is integrally formed inside the leg plate 110 and protrudes from the leg plate 112. The protruding dimension of this guide wall 112 from the leg plate 110 is slightly smaller than the dimension from the upper surface of the pedestal 12 to the guide surface 18 of the negative film conveyance path 16.
A gap is created between the tip of the guide surface 18 and the guide surface 18. Further, this gap dimension is slightly larger than the wall thickness dimension of the negative film 17 to ensure a conveyance path for the ends in the width direction of the negative film. An upper base 114 for guiding the surface (upper surface) of the negative film is formed between the guide walls 112, and as a result, the negative film conveyance path covers the entire periphery of the negative film 17, as shown in FIG. can be covered. This prevents the negative film 17 from meandering or floating when the negative film 17 is conveyed, and the amount of conveyance of the negative film 17 is controlled by the drive control amount (for example, the number of drive pulses) of the conveyance rollers 30, 32, and 34. The positioning accuracy of the negative film 17 can be improved. Slope portions 116 and 118 are formed at the front and rear ends of the upper base 114 in the negative film conveyance direction to facilitate insertion and ejection of the negative film 17.

Moreover, between the guide walls 112, idle rollers 120, 122, and 124 are provided, corresponding to the conveyance rollers 30, 32, and 34, and the opening/closing cover 14 is closed. By this, this idle roller 1
The negative film 17 is sandwiched between the rollers 20, 122, 124 and the transport rollers 30, 32, and 34, so that transport force can be transmitted to the negative film 17.

The guide wall 112 is formed almost continuously along the negative film transport direction, but a notch 126 is provided in a portion corresponding to the notch detection pin 88, so that the notch detection pin 88 is formed when the opening/closing cover 14 is closed. and the guide wall 112 so as not to interfere with each other.

An upper mask 130 having an opening 128 at a position corresponding to the through hole 106 is disposed at the center of the upper base 114 in the negative film transport direction. The upper mask 130 is attached to the mask base 132 via the sloped side surface.
is fixed to.

The mask base 132 is disposed over almost the entire bottom surface of the cover body 100, and a solenoid body 134 is fixed thereto. The tip of the plunger 136, which moves axially when the solenoid body 134 is energized, is fixed to the cover body 100, and the plunger 136 and the cover body 10
The relative position with respect to 0 is not changed. Therefore, when the solenoid body 134 is energized, the plunger 136 moves axially and is drawn into the solenoid body 134, but when the opening/closing cover 14 is in the closed state,
In reality, the solenoid body 134 is moved in the axial direction of the plunger 136, and as a result, the mask base 1
32 is adapted to be moved along the side surface of the cover main body 100 from the base toward the distal end. This movement causes
The upper mask 130 can be brought into close contact with the printing opening 22 of the negative film transport path 16, and the negative film 17 positioned on the optical axis P can be held therebetween.

Here, a pair of support poles 138 are erected from the base 12. This support pole 138 is pivotally supported in a circular hole 140 provided in the pedestal 12, and its base is attached to the pedestal 12.
The diameter is enlarged at the lower side of the hole 140, and is prevented from coming out from the circular hole 140. Further, the distal end portion of the support pole 138 is also formed with an enlarged diameter portion 142 having an arcuate surface. A compression coil spring 144 is attached to each of the support poles 138, and the urging force of the compression coil spring 144 urges the support pole 138 to axially move upward in FIG. 4.

On the other hand, the mask body 100 of the opening/closing cover 14 has a long hole 1.
46 is provided and corresponds to the support pole 138. As a result, when the opening/closing cover 14 is moved in the closing direction (rotated around the bar 102), the hook 8
2 engages with the latch portion 80, the enlarged diameter portion 142 of the support pole 138 enters the elongated hole 146, and the cover body 100
It will come into contact with the bottom of the Since the biasing force of the compression coil spring 144 attached to the support pole 138 is stronger than the pressing force due to the own weight of the openable cover 14, the openable cover 14 is held in a state supported by the support pole 138 ( (See Figure 4).

In this state, the angle between the pedestal 12 and the opening/closing cover 14 is
The angle is about 10°, and this position is used for manual operations such as insertion and replacement of the piece negative. In addition, when the opening/closing cover 14 is to be completely closed, the operator presses the opening/closing cover 14 and engages the hook 82 with the latch portion 80 .

(Configuration of Barcode Detection Mechanism, etc.) By the way, in the negative carrier 10 according to the present embodiment, when conveying the negative film 17, the conveyance rollers 30, 32.
34 pulse control, and at this time it is necessary to detect the first image frame 17A of the negative film 17.

Further, the negative film 17 is made up of a plurality of rolls connected by splice tape, and it is necessary to detect the image frame 17A again when passing through the connected portion. Furthermore, it is necessary to detect the frame number and the bar code indicating the film type attached to a portion of the negative film 17 other than the image frame 17A to obtain the presence or absence of printing and exposure correction information. The negative carrier of this embodiment incorporates the detection mechanism described above, and its configuration will be explained below.

As shown in FIG. 1, on the upstream side of the printing opening 22 of the negative film transport path 16, a light projecting section 148 of the density detection sensor and a light projecting section 150 of the splice detection sensor are arranged in order from the front side in the direction of transport of the negative film 17. is installed. These light projecting sections 148 and 150 are flush with the negative film transport path 16.

A green light beam is emitted from the light emitting section 148 of the density detection sensor and is transmitted through the negative film 17 being conveyed.
This transmitted light can be detected by a light-receiving section 152 of the concentration detection sensor, which is opposed to the sensor 8. Here, since the image frame 17A has a higher density than parts other than the image frame, the edge of the image frame 17A can be detected by the detection value by the density detection sensor. The distance between this detection position and the optical axis P is predetermined, and the image frame 17A of the negative film 17 is reliably positioned at the printing position by driving the conveying rollers 30, 32, and 34 a predetermined number of pulses from the time of edge detection. can do.

On the other hand, infrared light is emitted from the light projecting section 150 of the splice detection sensor and is transmitted through the negative film 17 being conveyed, and is opposed to the light projecting section 150 when the opening/closing cover 14 is closed. This transmitted light can be detected by the light receiving section 154 of the splice detection sensor. Here, when the splice tape passes, the detected value at the light receiving section 154 is different, and the connected portion of the negative film 17 can be detected by this detection.

Cutout portions 156 are provided at both ends in the width direction of the negative film transport path 16 in the light projecting portion 152 of the splice detection sensor so that the width dimension is expanded. The notch 156 has a rectangular hole 158 penetrating to the lower part of the pedestal 12.
are provided with two each, and each notch 1
A light source 160 is embedded between the 56 rectangular holes 158.

A movable block 162 is housed in each of the rectangular holes 158, and can be moved slightly toward the center of the negative film 17 in the width direction by the biasing force of a biasing means (not shown).

A circular hole 164 is provided in the upper end surface of the moving block 162, and corresponds to a pin 168 attached to a driven block 166 provided on the mask base 132 of the opening/closing cover 14. The driven block 166 is disposed in the cutout portion of the guide wall 112, and its side surface serves as a guide wall. The driven block 166 is also similar to the moving block 16.
2, it is movable in the width direction of the negative film 17, and when the opening/closing cover 14 is closed and the pin 168 is inserted into the circular hole 164, the moving block 162 and the driven block 166 are integrated. It is said that it is possible to move to Here, if a slight meandering occurs during conveyance of the negative film 17, it is possible to always support the widthwise ends of the negative film 17 by following the movement locus of the widthwise ends of the negative film 17. ing.

A barcode detection sensor 170 is embedded between the pins 168 of each driven block 166.

This barcode detection sensor 170 is arranged in correspondence with the light source 160, and the light 1160 passes through the negative film 1.
The barcode attached to 7 (the barcode on the top of the page in Figure 1 indicates the frame number, and the barcode on the bottom indicates the film type)
can be reliably read.

(Configuration of rotational movement mechanism for negative carrier 10) The negative carrier 10 configured as described above is loaded into a printing position of a printing device (not shown).As shown in FIG. At the negative carrier loading position, a pair of positioning pins 172 are provided in the longitudinal direction of the apparatus with the optical axis as the center. Further, as shown in FIG. 10, a disk 174 serving as a support plate is attached to the back side of the negative carrier 10 and is centered on the optical axis P. On the disk 174,
A circular hole 176 serving as positioning means is provided corresponding to the positioning pin 172.

Therefore, when loading the negative carrier 10 into the printing apparatus, the positioning pin 172 is inserted into the circular hole 176 to determine the relative position.

The disc 174 is housed in a receptacle 180 of the member 178 provided on the back side of the negative carrier 10, and supports the outer periphery of the disc 174. As shown in FIG. 11, the receiver of the disc 174 has a plurality of locations (
In this embodiment, circular recesses 182 are provided at four locations.
A ball 184 is accommodated. A portion of the ball 184 protrudes from the recess 182, and the receiver is attached to the bottom surface 1 of the member 178.
86. As a result, the receiver member 178 is supported by the ball 184, and the receiver member 178 and the disc 176 can rotate relative to each other about the optical axis P.

Here, the receiver has a rib 188 oriented toward the optical axis P at the opening corner of the member 178, and a rib 190 projecting in the radial direction at the upper end of the disk 174 in FIG. There is. As a result, the member 178 and the disc 174 are prevented from being pulled out, and at the same time, the receiver can be slightly moved in the direction of the optical axis P. The receiver has the ball 1 on the member 178.
A circular hole 192 serving as a locking means is provided corresponding to 84, and when the disc 174 is fixed and the member 178 rotates and the ball 184 is brought into correspondence with the circular hole 192, the receiver is inserted into the member 178. The ball 184 enters the circular hole 192 under its own weight. The circular hole 192 is formed with a sloped surface 193 which is a releasing means and has a tapered shape whose diameter gradually becomes smaller from the side where the ball 184 enters, and the receiver applies a rotational force to the member 178 with a predetermined force or more. Accordingly, ball 1
84 can be pulled out again along the slope portion 193 of the circular hole 192.

When the ball 184 enters the circular hole 192, the member 178 of the receiver and the disk 174 come into surface contact, so the coefficient of friction increases, and the member 1780 of the receiver is prevented from rotating. This rotation blocking position is located at the photographic paper (
A position where the conveying direction of the negative film 17 (not shown) matches the conveying direction (first position), and a position where the conveying direction of the negative film 17 (not shown) is perpendicular to each other (second position). That is, the negative film 17
If the image frame 17A photographed in is full size, it may be parallel to the transport direction of the photographic paper, but if the image frame size is half size, the orientation of the image frame is tilted 90 degrees with respect to the full size. Therefore, the negative carrier IO itself is rotated 90 degrees so that it can be used in common with full-size photographic paper.

Incidentally, since the spacing between the positioning pins 172 of the printing device differs depending on the model, in this embodiment, two pairs of circular holes 194 and 196 are provided in addition to the circular hole 176 to accommodate three types of spacing. ing. In this case, the circular hole 19
4.196 is provided at a position shifted by 90° around the axis, taking advantage of the fact that the negative carrier 10 is rotatable.

This prevents the circular holes from interfering with each other and allows three types of positioning pins to be accommodated.

The tip of a diffusion plate 198 installed in the printing device is inserted into the center of the disc 174 and the receiver member 178. Therefore, when the negative carrier 10 is loaded into the printing device, the opening at the tip of the diffuser plate 198 is shielded from light, making it possible to perform the printing process. In this embodiment, completion of loading of the negative carrier IO is detected by the presence or absence of the diffuser plate 198. That is, the receiver member 178 includes the diffusion plate 19g.
A light projecting section 200 and a light receiving section 202 of the photosensor are installed with an arrangement space in between, and normally the light beam from the light projecting section 200 reaches the light receiving section 202. Here, the diffusion plate 198 due to the loading of the negative carrier 10 into the printing device
In the arrangement state in the arrangement space, the light beam from the light projecting section 200 is blocked by the diffuser plate 198 and does not reach the light receiving section. As a result, negative carrier 1
The loaded state of the 0 can be confirmed at the detection location of the photosensor.

Further, the receiver member 178 is provided with a square groove 204 on the surface facing the disc 174, and a limit switch 206 is housed in the square groove 204. A contact 208 of the limit switch 206 is projected toward the disk 174. As a result, the receiver is in a state in which the member 178 is supported by the ball 184 (in the middle of rotation), and in a state in which the member 178 and the disc 174 are in surface contact (positioned for baking). state), the contactor 208 is activated and the contact of the limit switch 206 can be switched. Therefore, by detecting the conduction state of the limit switch 206, it is possible to determine whether the negative carrier 10 is positioned at a proper printing position.

The operation of this embodiment will be explained below.

First, a circular hole corresponding to a positioning pin is selected depending on the type of printing apparatus into which the negative carrier 10 of this embodiment is loaded.

In this example, circular holes 176.194.1 with three types of spacing dimensions are used.
96 is provided and is applicable to all printing devices currently in use.

After a circular hole is selected (one of the circular holes 176, 194, and 196), the circular hole is matched with the positioning pin 172, and the positioning pin 172 is inserted into the circular hole.

Here, it is determined whether the negative film 17 to be printed is full size or half size, and whether the applied circular hole is in the normal position or in a position shifted around the 90° axis is selected. This selection allows the following four positions.

(2) When the circular hole is in the normal position for full size: In this case, the negative film transport path 16 and the transport direction of the photographic paper are aligned, so the negative carrier 10 is loaded in the same manner as before, and positioning is completed.

■When the circular hole is rotated 90 degrees around the axis in a full size case In this case, when loading the negative carrier 10, the negative film transport path and the photographic paper transport direction are perpendicular to each other, so the negative carrier 10 is loaded. First, the negative carrier 10 is placed on a table having a large friction coefficient, such as a rubber plate, and the negative carrier 10 is rotated by an operator. Due to this rotational force, the ball 184 on the disc 174 is guided to the slope part 193, and the receiver is moved to the member 1.
The receiving member 178 that comes out from the circular hole 192 of 78 is supported by the disc 174 via the ball 184. Thereby, the coefficient of friction becomes extremely small, and the negative carrier 10 can be rotated smoothly. Since the balls 184 and the circular holes 192 are provided at every four locations around the axis, when the negative carrier 10 rotates 90 degrees, the balls 184 and the circular holes 192
84 corresponds to the circular hole 192. Here, the ball 184 enters the circular hole 192 due to the weight of the negative carrier 10, and the member 178 and the disc 174 come into surface contact with each other, increasing the coefficient of friction and being fixed. In this state, the positioning pin 172
Positioning is completed by inserting the selected circular hole into.

(2) When the circular hole is in the normal position for half size First, load the negative carrier 10 in the normal state. Next, negative film 1
Since the image frame photographed at No. 7 is half size, the operator rotates the negative carrier 10 by 90 degrees to match the conveyance direction of the photographic paper. In this case, since the position of the disc 174 is fixed by the positioning pin 172, it can be easily rotated as explained in the above (2).

(2) When the circular hole is rotated 90 degrees around the axis in a half size case In this case, it is sufficient to rotate the negative carrier 10 by 90 degrees before loading it into the printing device.

In addition, when the negative film 17 is a mixture of full size and half size, conventionally the negative carrier had to be removed from the printing device and changed direction, but this embodiment In this case, the orientation of the positioning pin 172 can be changed while it is inserted into any of the circular holes 176, 194, and 196, improving work efficiency.

When the loading of the negative carrier IO to the proper position is completed, the negative film 17 is supplied. As shown in FIG. 3, the leading end of the negative film 17 is inserted from the back side of the page (left side in FIG. 2) with the openable cover 14 closed. As a result, the negative film 17 is held between the transport rollers 30, 32, 34 and the idle rollers 120, 122, 124, and is guided and transported along the negative film transport path 16 by applying transport force.

In the negative film transport path 16, the negative film 17 first passes between the light projecting section 148 and the light receiving section B152 of the density detection sensor. Here, since the density of the image frame 17A is significantly different from the other densities, the edge of the image frame 17A can be detected.

The first image frame 17A can be properly positioned on the optical axis P by driving the conveying rollers 30, 32, 34 for a predetermined number of pulses from the time when this frame edge is detected. Thereafter, by conveying the negative film 17 every predetermined number of pulses, the image frames 17A can be successively positioned on the optical axis P.

A light projecting section 150 and a light receiving section 154 of the splice sensor are provided downstream of the density detection sensor, and the negative film 17
passes between them. Thereby, the connected portion of the negative film 17 can be detected, and if the connected portion is detected, a new signal of the different gender of the orderer is communicated to the main body of the printing apparatus.

Further, the barcode detection sensor 170 can read the barcode indicating the frame number and the barcode indicating the film type of the negative film 17 during transportation, so whether the image frame 1'? A can be specified, and furthermore, exposure can be corrected depending on the difference in film type.

Here, the barcode detection sensor 170 is tracked by the moving block 162 via the pin 168, so even if the negative film 17 meanderes slightly and the barcode deviates from its normal position, the barcode detection sensor 170 also responds accordingly. This prevents barcode reading errors.

The notch detection pin 88 enters the notch 17B of the negative film 17 for the image frame 17A that has moved near the optical axis P, and the presence or absence of the notch 17B can be detected, thereby determining whether or not the image frame 17A is properly printed. can do. In particular, since the notch detection pin 88 is disposed slightly upstream of the optical axis position, the negative film 17 only needs to be further advanced by a slightly further distance and stopped at the optical axis position, allowing rapid conveyance. Further, since the notch 17B is detected slightly upstream of the printing stop position, the notch 17B can be reliably detected even in the case of a piece negative having six or four image frames.

Next, when the printing of one negative film 17 is completed and the next negative film 17 connected by splice tape is being photographed in half size, the printing aperture 22 is changed. This change is made because the operating section 58 is currently in the first position.
Grip this and slide it to the second position in the direction of the burning opening 22. By this sliding operation, the partition plate 54 is exposed from the lower surface of the opening, and both ends of the printing opening 22 in the negative film transport direction are closed, thereby forming a half-size opening. That is, the opening can be easily changed between the full-size opening and the half-size opening by simply sliding the operating section 58, and the change can be made even when the negative film 17 is on the negative film transport path 16. In this case, the movement trajectory of the partition plate 54 and the notch detection pin 88 do not interfere with each other.

Since both widthwise ends of the negative film conveyance path 16 are substantially flush from the insertion side to the discharge side of the negative film 17, there is no possibility that the negative film 170 may be caught on the conveyance holder of the negative film 17 during conveyance. There will be no hindrance. Therefore, the meandering during conveyance of the negative film 17 is significantly reduced compared to the conventional structure, and bar codes can be read accurately.

In addition, since the negative film 17 is entirely covered, there is no bending in the thickness direction of the negative film 17, and the number of feeding pulses by the conveying rollers 30, 32, and 34 and the actual feeding amount of the negative film 17 are ensured. matches, image frame 17
The positioning accuracy of A is improved.

Next, when printing is performed using a piece negative, the release operation section 78 provided at the center of the operation panel 56 is pushed down.

As a result, the latch 74 rotates about the shaft 76, and the engagement of the latch portion 80 with the hook 82 of the opening/closing cover 14 is released.

When the engagement between the latch portion 80 and the hook 82 is released, the opening/closing cover 14 rotates in the direction of opening around the bar 102 due to the biasing force of the compression coil spring, and the enlarged diameter portion 14 at the tip of the support ball 138 The angle formed with the pedestal 12 is approximately 10
It is held in the ° position. As a result, the sides of the negative film transport path 16 are opened when viewed from the operation panel 56, and the negative film 17 can be taken in and out. At this time, the operation panel 5
Since the surfaces of the film 6 and the pedestal 12 are substantially flush, the negative film 17 can be smoothly taken in and taken out without damaging it.

After inserting the piece negative, the opening/closing cover 14 is pushed down against the biasing force of the compression coil spring 144, and the hook 82 is engaged with the latch portion 80. Next, by operating the operation button 72 on the operation panel 56, a predetermined image frame of the negative film 17 is positioned at the printing position.

Next, when performing maintenance on the negative carrier 10, after releasing the engagement between the latch section 80 and the hook 82, the operator grasps the opening/closing cover 14 and lifts it in the direction of opening. Pedestal 1 as shown in
2 and the opening/closing cover 14 can be opened until the angle formed by the opening/closing cover 14 becomes approximately a right angle. Thereby, the negative film transport path 16, the area around the printing opening 22, the area around the upper mask 130, etc. can be easily replaced, cleaned, and the like.

In particular, since the solenoid main body 134 and the plunger 136 are attached to the opening/closing cover 14 side, the opening/closing cover 1
It does not interfere with the case of opening No. 4.

In this embodiment, the member 178 is rotatably supported by the ball 184 with respect to the disc 174, but the ball 184 is
The number of rollers not limited to 84 may also be used. Also, ball 1
84 enters the circular hole 192, the negative carrier 1
0 was positioned, but a toothed portion is provided at a place other than the ball 184, for example, on the outer periphery of the disc 174, and a claw portion with elastic force is attached to the member of the receiver corresponding to this toothed portion, and the toothed portion and The positioning may be performed by engaging the claw portion.

〔Effect of the invention〕

As explained above, the film carrier according to the present invention has the excellent effect that the film transport direction can be changed in accordance with the size of the image frame while the film carrier is loaded into the printing device.
