Abstract

PROBLEM TO BE SOLVED: To eliminate the need of a zoom lens which is expensive, large and heavy and to provide various kinds of projection magnification with an inexpensive, compact and light constitution by changing and controlling the length of an optical path and the position of a lens in accordance with the projection magnification. SOLUTION: A control part adjusts the position of a lens part 360 in a horizontal direction and the position of a V mirror member 355 in the horizontal direction in accordance with a projection magnification decided according to the width of a frame image recorded on a photographic film F and to the width of photosensitive material for printing P moved by a moving mechanism. Since deviation of the real position of the lens from a lens control position L has a nearly linear relationship to the projection magnification, the position of the lens is excellently controlled by an arithmetic expression to obtain a lens position correction constant. Since the deviation of the real position of the member 355 from a V mirror control position V has a nearly linear relationship to the projection magnification, the position of the member 355 is excellently controlled by an arithmetic expression to obtain a V mirror position correction constant.

When exposing a frame image recorded on the photographic film F at a predetermined magnification m ₀ onto the printing photosensitive material P conveyed at the 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, before starting the projection printing process, the optical system section 350 described below is prepared.

First, the control unit 110 controls the carriage 31

Of the frame image (the length of the frame image in the "moving direction of the film carrier 250 by the carrier moving mechanism 300" and the length in the moving width direction) are acquired. Further, print width information relating to the width of the photosensitive material P for printing is acquired from information on the magazine 410 held by the magazine holding unit 400.

The desired print width and frame size information may be input from the operation input unit 150. In this case, the control unit 110 determines whether the print width and frame size information input from the operation input unit 150 are the information acquired from the magazine 410 held by the magazine holding unit 400, the type and orientation of the film carrier 250, and the film mask. 251
Check if it matches the information in
The display requesting the replacement may be displayed on the monitor 190, and if the display matches, the process may proceed to the next stage.

Second, the control unit 110 obtains a projection magnification M from the print width WP of the print width information and the length WF of the frame image in the moving width direction of the frame size information by the following equation.

M = WP / WF A two-dimensional LUT (lookup table) in which the projection magnification M is set is set in advance for each combination of the print width and the length of the frame image in the moving width direction. The projection magnification M may be obtained from this two-dimensional LUT from the print width information and the length of the frame image in the moving width direction of the frame size information.

Third, the control section 110 obtains a lens position correction constant α by substituting the projection magnification M into a preset lens position correction constant calculation formula α (M) shown below.

Α (M) = A × M + α0 Fourth, the control unit 110 sets a predetermined V
By substituting the projection magnification M into the mirror position correction constant calculation formula β (M), a V mirror position correction constant β is obtained.

Β (M) = B × M + β0 Fifthly, the control unit 110 substitutes the projection magnification M into a preset optical path length calculation formula U (M) shown below to obtain the optical path length U
Get.

U (M) = (2 + M + 1 / M) × f Sixth, the control unit 110 calculates the projection magnification M and the optical path length U in a preset lens control position calculation formula L (M, U) shown below. To obtain the lens control position L.

L (M, U) = U / (M + 1) -La-α Seventh, the control unit 110 sets a predetermined V
Substituting the optical path length U into the mirror control position calculation formula V (U),
The V mirror control position V is obtained.

V (U) = U / 2−Va−β Eighth, the control unit 110 determines the obtained lens control position L
Then, the stepping motor 361 is controlled by a control signal so as to move and position the lens unit 360, and the control signal is used to move and position the V mirror member 355 to the obtained V mirror control position V. The stepping motor 356 is controlled.

Ninth, as shown in FIG. 7A, when the carriage 310 is stopped at the home position,
The first frame image recorded on the photographic film F is set in the opening 252 of the mask member 251 of the film carrier 250. At this time, the home position sensor SH detects that the carriage 310 is at the home position.

Then, the following steps are repeated, and projection printing is performed.

First, in the state shown in FIG. 7A, the light emitted from the viewer 740 passes through the frame image of the first frame recorded on the photographic film F, and the operator moves the frame of the first frame. Observe the image. Then, the operator adjusts the position accurately to the opening 252 of the mask member 251 of the first frame image, observes the first frame image, and determines whether correction such as density feria or color feria is necessary. , The correction value is input from the operation input unit 150. On the other hand, the photosensitive material P for printing is located on the upstream side in the moving direction from the position where the front end is detected by the front end position detection sensor SP, and the moving mechanism 5
00 and is in a standby state.

When the input from the operation input section 150 is completed, as shown in FIG. 7B, the film carrier 250 holds the photographic film F (the mask member 2).
With the photographic film F pressed by 51), the carriage 310 is moved leftward in FIG. 7 (forward movement). 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. The light amounts of B, G, and R of the light transmitted through the frame image are measured by the photometric member 390.

[0124] transport speed of the carriage 310 at the time of forward movement (photographic film F), as shown in FIG. 8, a fast moving speed V _H from the transfer velocity V ₀ which during scanning exposure. 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 as to measure the full screen density of the recorded frame image on the photographic film F, no problem occurs even faster transport speed V _H from 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.

Then, as shown in FIG. 7C, when the carriage 310 reaches the start position, 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 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. In other words, at this stage, the preparation for transfer for scanning by the film carrier 250 is completed.

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. 7D, when the leading end position detection sensor SP detects the leading end of the printing photosensitive material P moving by the moving mechanism 500, immediately the first frame of the photographic film F is moved. In order to scan an image, the carriage 310 is moved rightward in the drawing at a predetermined speed V ₀ , and is synchronized with the photosensitive material P for printing conveyed by the moving mechanism 500.

Then, as shown in FIG. 7E, the leading end of the frame image recorded on the photographic film F is
After passing through a position corresponding to the printing slit 752 (FIG. 5) of FIG.
Pass through. 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. Opening 252 of mask member 251 of film carrier 250
This is to avoid a loss of light quantity due to the edge of.

Thereafter, the carriage 310 moves at the 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. 7 (f), the scanning exposure ends when the rear end of the printing photosensitive material P passes through the imaging surface area a. At this time, that is, after the printing photosensitive material P passes through the imaging surface area a, the rear end of the frame image recorded on the photographic film F passes through a position corresponding to the printing slit 752 of the slit portion 750. Is to prevent the above-mentioned margin and light quantity loss.

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 FIG. Then, as shown in FIG. 7A, when the carriage 310 is at the home position, the home position sensor SH
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 transported at a transport speed V _H higher than the transport speed V ₀ during the scanning exposure as shown in FIG. .

Then, while the carriage 310 is stopped at the home position, the film carrier 250
Releases the pressure bonding of the photographic film F by the mask member 251, and the operator feeds the frame so that the second frame image recorded on the photographic film F is located in the opening 212. Then, when the operator finishes the frame feeding, the operator inputs a crimping instruction from the operation input unit 150,
With this input, the photographic film F is pressed by the mask member 251.

By repeating such a process,
A correction value is input for each frame of the photographic film F, and scanning exposure is performed.

As described above, in the present embodiment, the transport speed of the carriage 310 (photographic film F) is higher than the transport speed V ₀ during scanning exposure on the photosensitive material P for printing. The carrier moving mechanism 300 is controlled so that the transfer speed V _H when moving without scanning exposure 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 the frame image recorded on the photographic film F onto the photosensitive material 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 high speed, the photographic film is not related to the scanning exposure (in the present embodiment, the photographic film is moved from the home position to the start position ( A large amount of time is required for forward movement) and for moving to the home position after the completion of 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.

As described above, the projection printing apparatus 200 of this embodiment has a simple, small, lightweight mechanism for changing the optical path length U from the object plane area b to the image plane area a. It is inexpensive, and the mechanism for changing the position of the lens 371 is simple, small, lightweight, and inexpensive, and can adjust the projection magnification while focusing. Therefore, the optical path length U from the object plane area b to the imaging plane area a and the position of the lens can be changed in accordance with the projection magnification M, so that an expensive and large zoom lens is unnecessary, and various projection magnifications can be obtained. Can respond. Therefore, while being a projection printing apparatus capable of adjusting the focus while adjusting the projection magnification M, the projection printing apparatus can be synergistically cheaper, smaller, and lighter. Further, in the projection printing apparatus 200, the lens 371 may be a lens having a fixed focal length, and the lens can be an inexpensive, small, and lightweight lens, and the projection printing apparatus can be made cheaper, smaller, and lighter. Further, since the optical path length U from the object plane area b to the imaging plane area a is changed by changing the position of the V mirror member 355, the projection magnification is simple, small, light and inexpensive. Despite being a projection printing apparatus that can adjust the focus while adjusting the image quality, the projection printing apparatus can be made more synergistically cheaper, smaller, and lighter.

Next, regarding the calculation flow of the control information of the present embodiment, the relationship between the lens control position L, the V mirror control position V, and the like of FIG. FIG. 10 is a schematic diagram illustrating the relationship between the lens control position Lw, the V mirror control position Vw, and the like at the first projection magnification of the present embodiment.

Then, the control unit 110 obtains a print size from the information from the set magazine 410 and the information of the set film carrier 250, its orientation and the mask 252, and obtains a print size from the obtained print size and the information of the mask 252. One projection magnification is obtained. Therefore, the V-mirror member 355 moves to and is located at the V-mirror control position Vw corresponding to the first projection magnification under the control of the control unit 110.

Then, when the operator inputs the focus adjustment mode from the operation input unit 150, that is, the control unit 110
When the operation input of the focus adjustment mode is input from the operation input unit 150, the process proceeds to S1, the lens control position L is slightly shifted, the projection exposure is performed many times, and the printing unit 570 prints the lens control position L on the back surface. Output many prints. Then, the lens control position Lw is input from the operation input unit 150.
Wait for input. Then, the operator observes the focus charts of a large number of obtained prints and inputs the lens control position Lw of the print with the best focus. Then, it waits for the input of the actual projection magnification Mw of the print with the best focus from the operation input unit 150. Then, the operator measures the actual length Cw of the index of the focus chart on the print with the best focus, and from the length Cf of the index of the focus chart recorded on a predetermined photographic film, obtains the following equation. Calculates and inputs the actual projection magnification Mw.

Mw = Cw / Cf The input lens control position Lw and the projection magnification M
w is stored in the memory of the control unit 110.

Then, the 135-size photographic film carrier 250 is set in the horizontal direction (the direction in which the film lane 260 extends in the left-right direction), and the focus chart recorded on the 135-size photographic film is applied to the mask 252. The position is set at this position (the length of the frame image in the moving width direction becomes approximately 23 mm), and the projection magnification is set to a second projection magnification as shown in FIG. ) Magazine (eg, 203 mm
A magazine containing a printing photosensitive material having a width is set. Then, the control unit 110 reads the information from the set magazine 410 and the set film carrier 2.
The print size is obtained from the information about the mask 252 and the print size, and the second projection magnification is obtained from the obtained print size and the information about the mask 252. Therefore, the control unit 110
, The V mirror member 355 moves to the V mirror control position Vt corresponding to the second projection magnification and is located there.

When the operator inputs the focus adjustment mode from the operation input unit 150, that is, the control unit 110
When the operation input of the focus adjustment mode is input from the operation input unit 150, the process proceeds to S2, in which the lens control position L is slightly shifted, the projection exposure is performed many times, and the printing unit 570 prints the lens control position L on the back surface. Output many prints. Then, the lens control position Lt is input from the operation input unit 150.
Wait for input. Then, the operator observes the focus charts of a large number of obtained prints and inputs the lens control position Lt of the print with the best focus. Then, input of the actual projection magnification Mt from the operation input unit 150 is waited. Then, the operator measures the length Ct of the index of the focus chart on the print with the best focus, and calculates the length Cf of the index of the focus chart recorded on the photographic film in advance by the following formula. Calculate the actual projection magnification Mw,
input.

Mt = Ct / Cf Then, the control section 110 stores the actual projection magnification Mt and the lens control position Lt in the memory of the control section 110.

Then, the flow proceeds to S3, where the control section 110 calculates the focal length f unique to each lens 371 of each projection printing apparatus 200 as follows. First, the V mirror member 35 in the case of the first projection magnification and the case of the second projection magnification
The difference ΔV between the position of No. 5 and the difference ΔL between the positions of the lens 371 is calculated by the following equation.

ΔV = Vt−Vw ΔL = Lt−Lw Then, based on the obtained difference ΔV between the position of the V mirror member 355, the difference ΔL between the positions of the lens 371, the first projection magnification Mw, and the second projection magnification Mt. The focal length f unique to each lens 371 of each projection printing apparatus 200 is calculated by the following equation.

F = (2 × ΔV + ΔL) / (Mt−Mw) From the obtained focal length f, an optical path length calculation formula U (M) shown below is also calculated.

U (M) = (2 + M + 1 / M) × f Then, the process proceeds to S4, where the control unit 110 sets the lens at the actual position Lcw, Lct of the lens at the first projection magnification Mw and the second projection magnification Mt. The deviation from the control positions Lw and Lt is calculated by the following equation. Note that the deviation amounts αw, α
t is a value unique to each lens 371 of each projection printing apparatus 200.

Αw = Lcw−Lw = f × (1 + 1 / M

6-Lt H1: Distance from the object plane area b to the center of the optical path of the first mirror 351 H6: Distance from the center of the optical path of the first mirror 351 to the origin position (L = 0) of the lens
The control unit 110 obtains a lens position correction constant calculation expression α (M) of the following expression from the shift amounts αw and αt at the first projection magnification Mw and the second projection magnification Mt.

Α (M) = A × M + α0 This is calculated by the following equation.

A = (αw−αt) / (Mw−Mt) α0 = αw−A × Mw Then, the process proceeds to S6, where the control unit 110 sets the V mirror at the first projection magnification Mw and the second projection magnification Mt. Member 35

55 to the origin position (V = 0) of H55: the distance from the imaging plane area a to the center of the optical path of the fourth mirror 354. Then, proceeding to S7, the control unit 110 determines the first projection magnification Mw and the second Shift amounts βw, βt at the projection magnification Mt
From the V mirror position correction constant calculation formula β
(M) is obtained.

Β (M) = B × M + β0 This is calculated by the following equation.

B = (βw−βt) / (Mw−Mt) β0 = βw−B × Mw Then, the process proceeds to S8, where the control unit 110 determines the obtained optical path length calculation formula U (M) and the lens position correction constant calculation formula. α (M) and V mirror position correction constant calculation formula β (M) are set.

As described above, according to the projection magnification M,
The control information for controlling the position of the lens and the position of the V mirror can be obtained and set.

Accordingly, the actual position L of the lens 371 is determined.
The shift amount α of the lens c from the lens control position L can be approximated by a straight line with the projection magnification M. Therefore, the position of the lens 371 can be favorably controlled by the lens position correction constant calculation expression α (M). Also, V at the actual position Vc of the V mirror member 355
Since the deviation amount β from the mirror control position V is in a linear approximation with the projection magnification M, the position of the V mirror member 355 can be favorably controlled by the V mirror position correction constant calculation formula β (M).

As described above, in the present embodiment, the first information (for example, Lw, Cw), which is information relating to the in-focus condition at the first projection magnification Mw, is larger than the first projection magnification Mw. Second information (for example, information on the in-focus condition at the second projection magnification Mt)
Lt, Ct) and control information (eg, α (M), β
(M), U (M)), it is possible to obtain control information capable of achieving good focus and good projection printing at various projection magnifications M.

In particular, a V mirror member 355 that reflects the optical path from the object plane area b to the image plane area a by 180 ° by combining two mirrors (second mirror 352 and third mirror 353) is provided. By changing the position of the mirror member 355, the optical path length can be changed.
Since the change amount of the optical path length U corresponds to twice the change amount of the position of the V mirror member 355, the change amount of the optical path length U corresponds to twice the change amount of the position of the V mirror member 355.
Since the projection printing apparatus 200 can easily obtain control information, it is possible to easily obtain control information capable of performing favorable projection printing in focus at various projection magnifications.

The lens 371 of the lens unit 370 set in the projection printing apparatus 200 of this embodiment is
Since the focal length cannot be adjusted, the lens has a fixed focal length. Therefore, as long as the device is not deformed or deteriorated, it is possible to perform good projection printing with focus on various projection magnifications using the control information obtained once.
