The processing unit casing 800 is a member indicated by cross-hatching in FIG. 2 and holds the development processing unit 600 and is placed on the floor. The processing unit casing 800 includes
It has a processing unit housing base 810 and a movable housing 850 that can move the processing unit housing base 810 in the horizontal direction, ie, the front-back direction (the direction perpendicular to the paper surface of FIG. 2). The processing unit casing base 810 is formed of the processing unit casing base 81.
0, the processing unit casing legs 821 and 83 provided integrally with
1 fixed to the floor. In addition, the moving housing 850

It is supported from the floor by a separate housing. Accordingly, it is possible to prevent the vibration generated in the development processing unit 600 from being transmitted to the projection printing apparatus 200 so much that the image quality of the exposed image is not deteriorated.

Further, since each member of the optical system section 350 is fixed at the time of projection printing and the frame image recorded on the photographic film F is fixedly held by the film carrier 250, the carrier moving mechanism 300 is strong against vibration. The unevenness is also less likely to occur in the movement of the film carrier 250 due to the movement of the film carrier 250.
Since the vibration generated at 00 is not so transmitted to the projection printing apparatus 200 and the movement of the photographic film F as well as the movement of the photosensitive material P for printing by the moving mechanism 500 is less likely to occur, the quality of the exposed image is reduced. Can be suppressed from being deteriorated by vibration.

However, the start sensor SS moves so that the distance to the slit 750 can be changed according to the projection magnification. It is provided to be able to. In the present embodiment, the tip position detection sensor SP uses the moving mechanism 500.
When the photosensitive material P for printing conveyed is detected, a signal thereof is used as a trigger to start the movement of the carriage 310.

When exposing a frame image recorded on a photographic film F at a predetermined magnification m ₀ onto a photosensitive material P for printing conveyed at a speed P ₀ , the transport speed V ₀ of the carriage 310 during scanning exposure is V ₀ = P ₀ / m ₀ is constant. The start sensor SS is disposed at a position separated from the slit 750 by a distance necessary for synchronizing the frame image recorded on the photographic film F with the photosensitive material P for printing. The transfer speed V ₀ in the present embodiment is set so that the frame image recorded on the photographic film F on the printing photosensitive material P is exposed (scanning exposure is performed) in order to perform good scanning exposure. Is constant.

First, in the state shown in FIG. 8A, with the carriage 310 stopped at the home position,
The film carrier 250 sets the frame image of the first frame recorded on the photographic film F in the opening 252 of the mask member 251 of the film carrier 250 by frame advance by the pair of transport rollers 263.

The transport speed of the carriage 310 (photographic film F) during the forward movement is higher than the transport speed V ₀ during the scanning exposure as shown in FIG. At the time of this forward movement, the photometry is performed as described above. However, this photometry does not capture the frame image recorded on the photographic film F, but uses the transmitted light amount of the frame image recorded on the photographic film F as RGB. was measured every, so photographic film F for measuring the full screen density of the recorded frame image to that, no problem occurs even faster transfer rate than the transfer velocity V _0. However, at the time of this photometry, it is preferable that the transfer speed of the carriage 310 be constant in order to obtain an accurate full screen density.

When the carriage 310 reaches the start position as shown in FIG. 10C, the start sensor SS detects that the carriage 310 is at the start position. When the start sensor SS detects that the carriage 310 is at the start position, the transfer of the carriage 310 is stopped. By this stage, the start sensor SS has determined that the frame image recorded on the photographic film F and the photosensitive material P for printing have a predetermined distance from the slit portion 750 (varies according to the magnification) necessary for synchronizing the photosensitive material P for printing. ) Have completed the move. Further, the light control section 213 (FIG. 3) is controlled based on the input correction value and the full-screen density of the photometric frame image, and is in a controlled light control state. That is, at this stage, the carriage 3
The transfer is ready for scanning by 10.

When the carriage 310 is located at the start position, the waiting photosensitive material P is moved to the moving mechanism 5.
00 by begin to move at a predetermined speed P _0. If the frame image recorded on the photographic film F can be synchronized with the photosensitive material P for printing, the movement of the photosensitive material P for printing may be started before the carriage 310 is located at the start position.

Then, as shown in FIG. 11D, when the leading end position detecting sensor SP detects the leading end of the moving photosensitive material P by the moving mechanism 500, the first frame of the photographic film F is immediately received. the carriage 310 in order to perform the scanning of the image, is moved at a predetermined speed V ₀ to the right in FIG. 11, synchronized with the photosensitive material for printing P conveyed by the moving mechanism 500 is taken.

Then, as shown in FIG. 12E, the leading end of the frame image recorded on the photographic film F is
After passing through a position corresponding to 50 printing slits 752 (FIG. 5), the leading end of the photosensitive material P for printing passes through the image forming area a. This is because the frame image recorded on the photographic film F has a margin for recording an image that cannot be observed with the viewfinder of an ordinary camera, and that portion is not exposed on the photosensitive material for printing. ,
This is to avoid a light amount loss due to the edge of the opening 252 of the mask member 251 (FIG. 5) of the film carrier 250.

Thereafter, the carriage 310 moves at a predetermined speed V
₀ , a linear image corresponding to the frame image transmitted through the frame image recorded on the photographic film F being transported together with the carriage 310 is projected on the imaging surface area a,
Photosensitive material for printing P is conveyed at a predetermined speed P ₀ by the moving mechanism 500, photosensitive material for printing P passes through the image plane region a.

Then, as shown in FIG. 13 (f), when the rear end of the printing photosensitive material P passes through the image forming area a, the scanning exposure is completed. At this time, that is, after the printing photosensitive material P has passed through the imaging surface area a, the rear end of the frame image recorded on the photographic film F is located at a position corresponding to the printing slit 752 of the slit portion 750 (FIG. 5). Is passed to prevent the above-mentioned margin and light amount loss. In addition, the leading end side of the photosensitive material P for printing is guided to the dead end 590 through the transport path switching unit 560 of the switchback mechanism 550.

Thereafter, when the scanning exposure of the first frame image recorded on the photographic film F is completed, the carriage 310
Is the carriage 31 by the home position sensor SH.
Until it is detected that 0 is at the home position, it continues to move rightward in the figure. And FIG.
As shown in FIG. 4G, when the carriage 310 is at the home position, the home position sensor S
H detects that the carriage 310 is at the home position, and stops the transfer of the carriage 310. After the scanning exposure of the first frame image recorded on the photographic film F is completed, the carriage 310 is moved as shown in FIG.
As shown in (5), the transfer speed is higher than the transfer speed V ₀ during scanning exposure. At this time, the photosensitive material P for printing is once completely stored in the dead end 590. Further, a new photosensitive material P for printing is fed to the standby position.

Then, as shown in FIG. 15 (h), the conveying direction of the printing photosensitive material P is reversed, and the printing photosensitive material P is transferred from the dead end 590 to the developing section 600.
The transport speed VH which is higher than the transport speed VD of the developing unit 600
Start transporting. When the leading end of the photosensitive material P for printing whose transport direction is reversed reaches the transport path switching unit 560 of the switchback mechanism 550, the first roller 568 of the transport path switching unit 560 of the switchback mechanism 550 is rotated clockwise. Then, the position of the second roller 561 is switched to a position where the photosensitive material P for printing is guided from the dead end 590 to the developing unit 600. At this time, the solenoid 565 (FIG. 7) not shown in FIG. 15 also moves so as to bias the solenoid 565 as described above.

The carriage 310 is stopped at the home position during the states shown in FIGS. During this time, the film carrier 250
Releases the pressure bonding of the photographic film F by the mask member 251 (FIG. 5).
Is advanced so that the second frame image recorded in the frame is located in the opening 212. Then, when the frame feed by the operator is completed, the operator inputs a pressure bonding instruction from the operation input unit 150, and the mask member 251 (FIG. 5) presses the photographic film F by this input.

When the input from the operation input unit 150 (FIG. 1) is completed, as shown in FIG.
In the state where the film carrier 250 holds the photographic film F, the carriage 310 is moved leftward in FIG. During the transfer, the opening 252 provided in the mask member 251 of the film carrier 250 passes over the slit 750, and thus the first frame recorded on the photographic film F uniformly illuminated by the illumination unit 210. B of the light transmitted through the frame image,
The light amounts of G and R are measured by the photometric member 390.

At this time, the leading end of the printing photosensitive material P is transported at a transport speed VH higher than the transport speed VD of the developing section 600, and reaches the entrance transport roller pair 611 at the entrance of the developing section 600. The entrance conveying roller pair 611 at the entrance of the developing section 600 conveys the photosensitive material P for printing at the conveying speed VD of the developing section 600.

Note that the state shown in FIG.
Until the state (i) shown in FIG. 6 is reached, the rocking member 582 of the accumulating mechanism 580 is separated from the guide 585 by the force from the pair of conveying rollers of the switchback mechanism 550 pressing the printing photosensitive material P from behind. Then, the leading end of the photosensitive material for printing reaches the entrance conveying roller pair 611 at the entrance of the development processing section 600.

When the carriage 310 reaches the start position as shown in FIG. 17 (j), the start sensor SS detects that the carriage 310 is at the start position. Then, when the start sensor SS detects that the carriage 310 is at the start position, the transfer of the carriage 310 is stopped as described in (c) shown in FIG. In the meantime, the leading photosensitive material P is transported by the developing unit 600 at the transport speed VD of the developing unit 600, and the trailing edge of the preceding photosensitive material P is transported at a transport speed VH higher than the transport speed VD of the developing unit 600.
As a result, the swinging member 582 of the accumulating mechanism 580 is further moved away from the guide 585 by the bending of the photosensitive material P for printing by the accumulating mechanism 580.

Further, from the state of (h) shown in FIG.
Until the state (j) shown in FIG. 7 is reached, the printing unit 570 performs printing on the back surface opposite to the photosensitive surface of the photosensitive material P for printing. In the state (j) shown in FIG. 17, the rear end of the photosensitive material P for printing is located in the printing unit 570 and not in the transport path switching unit 560, so that the first roller 568 of the transport path switching unit 560 is moved to the left. By rotating, the position of the second roller 561 is switched to a position where the photosensitive material P for printing is conveyed from the projection printing apparatus 200 to the dead end 590. At this time,
As described above, the solenoid 565 not shown in FIG.

The control unit 110 controls the current exposure start time of the printing photosensitive material P in accordance with the exposure start time and exposure time of the printing photosensitive material immediately before the exposure of the printing photosensitive material. The exposure time TP of the immediately preceding printing photosensitive material and the time T required for switchback from the last exposure start time of the printing photosensitive material.
The time after the exposure time of the photosensitive material for printing is subtracted from the sum of S and the exposure time of the photosensitive material for printing is set to be the time after the exposure time. The last exposure time TP of the photosensitive material for printing and the time T required for switchback
S is the length of the photosensitive material for printing in the transport direction LP, the length L1 in the transport direction from the position detected by the leading end position detection sensor SP to the entrance of the dead end 590, and the printing of the printing unit 570 from the entrance of the dead end 590 is completed. The length L2 in the longer transport direction to the rear end position of the photosensitive material P for printing or the exit of the transport path switching unit 560, the transport speed P ₀ of the photosensitive material P for exposure at the time of exposure, and the switchback mechanism 550 It is calculated from the transport speed VH after switchback according to the following equation.

TP = (LP + L1) / P ₀ TS = (LP + L2) / VH
After the current exposure start time of the printing photosensitive material P obtained by the above calculation, the printing photosensitive material P is transported to a position where the printing of the printing unit 570 ends, and the carriage 310 is positioned at the start position. are the begin to move at a predetermined speed P ₀ by the moving mechanism 500 for the next photosensitive material for printing P on standby. In addition, photographic film F
As long as the frame image recorded in the printer can be synchronized with the next photosensitive material P for printing, the movement of the photosensitive material P for printing may be started before the carriage 310 is located at the start position.

Then, as shown in (k) of FIG. 18, the carriage 310 is used to immediately perform scanning exposure of the second frame image of the photographic film F, as in (d) of FIG.
Is moved rightward at a predetermined speed V ₀ in FIG. 18, and is synchronized with the next photosensitive material P for printing conveyed by the moving mechanism 500. Also, by the time (k) shown in FIG. 18, the trailing end of the preceding photosensitive material P for printing is sent to the developing section 600, and at the same time, the swing guide 582 of the accumulation mechanism 580 is moved by gravity. By rotating, it comes into contact with the guide 585 and shields between the switchback mechanism 550 side and the development processing unit 600 side.

The printer processor of this embodiment repeats the steps from (e) shown in FIG. 12 to (k) shown in FIG. 18, ie, feeds the frame every frame of the photographic film F. , A correction value is received, and scanning exposure is performed according to the input correction value.
Transport.

The switchback mechanism 550 is provided with an accumulation mechanism 580 for accumulating the photosensitive material P for printing between the transport path switching section 560 and the development processing section 600. The material P is transferred from the dead end section 590 to the development processing section 600.
Can be conveyed at a conveying speed VH higher than the conveying speed VD of the developing section 600, so that the photosensitive material P for printing can be transferred to the developing section while the occurrence of jams is suppressed by the accumulation mechanism 580. Since the transfer can be performed at a high transfer speed VH to the entrance of 600, the time until switchback is completed can be shortened, and the total processing capacity can be increased.

As described above, in this embodiment, the film carrier 250 releases the fixing of the photographic film F and feeds the photographic film F by the time the exposure of one frame is completed and the exposure of the next frame is started. Then, since the photographic film F is fixed, the frame image recorded on the photographic film F can be satisfactorily fed and fixed, and the exposure can be performed while maintaining the flatness of the photographic film F. And prints of good image quality can be obtained.

The switchback mechanism 550 switches back the photosensitive material P for printing from the completion of exposure of one frame to the start of exposure of the next frame. Before exposing the photosensitive material P, the transport path switching unit 560 can be brought into a state where the photosensitive material P can be transported from the projection printing apparatus 200 to the blind alley 590, and is sent to the switchback mechanism 550 while exposing the next photosensitive material P for printing. The size of the print can be reduced, and the efficiency of obtaining a print can be improved.

The printing section 570 prints on the switched back photosensitive material P after the exposure of one frame is completed and the exposure of the next frame is started. While preventing the quality of exposure from deteriorating due to vibration as in the case of printing, the printing unit 570 is provided between the completion of exposure of one frame and the start of exposure of the next frame.
Prints on the photosensitive material P for printing.
Can be prevented from adversely affecting the next exposure of the photosensitive material P for printing, and a print of good image quality can be obtained.

The accumulating mechanism 580 is provided with a swing guide 582 for guiding the photosensitive material P for printing, and the swing guide 582 is provided with the photosensitive material P for printing.
Is flexibly held so as to be able to swing away from a position along the conveyance path of the photosensitive material P for printing, so that the leading end of the photosensitive material P for printing is developed by the swing guide 582 in the developing processing unit. The swing guide 582 can function as an accumulator because the swinging guide 582 moves away from a position along the conveyance path of the printing photosensitive material P due to the bending of the printing photosensitive material P while being guided well to the entrance of 600. . Then, while suppressing the occurrence of jam by the accumulation mechanism 580, the photosensitive material P for printing is removed from the developing processing unit 6
Since the transfer can be performed at the high transfer speed VH to the entrance of 00, the time until the switchback is completed can be shortened, and the total processing capacity can be increased.

Also, the shielding member 583 of the swing guide 582
However, the photosensitive material P for printing uses the switchback mechanism 550.
While the sheet is not conveyed to the developing unit 600, the switchback mechanism 550 and the developing unit 600 are shielded. As a result, the photosensitive material P for printing can be switched back mechanism 550 without any special power source.
While the sheet is not conveyed to the development processing unit 600, the switchback mechanism 5
Since the space between the 50 side and the development processing unit 600 side is shielded,
Corrosive gas, water vapor, and the like, which are likely to be generated in the development processing unit 600, may cause the switchback mechanism 550 and the projection printing apparatus 200
Hardly leaks to the outside, and can suppress the occurrence of troubles such as corrosion and dew condensation. And especially, the switchback mechanism 550
Transports the photosensitive material P for printing from the dead end 590 to the entrance of the developing section 600 at the transport speed V of the developing section 600.
When transported at a transport speed VH faster than D, the shielding member 583
Since the opening time of the opening is shortened, corrosive gas, water vapor, and the like, which are likely to be generated in the development processing unit 600, are hardly leaked by the switchback mechanism 550, the projection printing apparatus 200, and the like, so that troubles such as corrosion and dew condensation are more likely to occur. Can be suppressed.

The transport path switching unit 560 of the switchback mechanism 550 includes a first roller 5 rotatable in both forward and reverse directions.
68, and a second roller 561 that forms a roller pair with the first roller 568 and swings depending on the rotation direction of the first roller 568 and has a different position. No special drive source is required for switching
Just urge with an inexpensive member such as solenoid 565,
The transport path can be switched reliably and stably.

The projection printing apparatus 200 exposes the photosensitive material P for printing while moving the printing material P in the horizontal direction, and conveys the photosensitive material P for printing from the projection printing apparatus 200 to a half of the entrance side of the dead end 590. Since the road is substantially horizontal, stable movement can be easily performed, and good exposure can be performed.

The transport speed of the carriage 310 (photographic film F) is higher than the transport speed at the time of scanning exposure on the printing photosensitive material P, and the carriage 310 (photographic film F) is moved without scanning exposure on the printing photosensitive material P. The carrier moving mechanism 300 is controlled so that the transfer speed at the time of movement is higher. Accordingly, when scanning exposure is performed by moving the photographic film F, the time required for the movement of the carriage 310 (photographic film F), which is not related to the scanning exposure, in the reciprocating motion necessarily provided, is reduced. The ability can be improved.

In particular, when exposing a frame image recorded on the photographic film F onto the photosensitive material P for printing, the transfer speed of the carriage 310 (photographic film F) is also varied in order to correspond to a wide range of magnifications. For example, if the carriage 310 is always moved at a high magnification when the carriage 310 is moved at a low speed, the movement of the photographic film unrelated to the scanning exposure (in this embodiment, the movement from the home position to the start position). A large amount of time is required when moving forward (and when moving to the home position after the completion of the scanning exposure on the printing photosensitive material P), resulting in a reduction in processing speed. However, according to the present embodiment, such a problem is solved by the above-described configuration.
