BACKGROUND OF THE INVENTION
The present invention relates to a film image positioning method and a film carrier, and more particularly to a film image positioning method for conveying a photographic film to position a film image at a predetermined position and a film carrier to which the film image positioning method can be applied.
[0002]
[Prior art]
Conventionally, in a photographic printing apparatus for printing an image recorded on a photographic film onto a photosensitive material, a film carrier for conveying the photographic film is provided, and the photographic film on which the image to be printed is recorded is set on the film carrier. . The film carrier has a screen detection sensor for optically detecting the position of the image recorded on the photographic film. The photographic film is predetermined after the photographic film is conveyed and the screen detection sensor detects the position of the image. In addition, the images are sequentially positioned at the exposure position where the exposure light is irradiated by conveying a certain amount. However, since the distance from the screen detection sensor to the exposure position varies depending on the individual film carrier, the image may not be positioned at the exact exposure position. In this case, the amount of photographic film transported when positioning the image Need to be corrected.
[0003]
Conventionally, as a method of correcting the transport amount of photographic film, an operator directly looks at the image position when the film carrier transports a certain amount of photographic film so that the image of the photographic film is positioned at the exposure position. A method has been employed in which a positional deviation amount of the image position with respect to the image is measured, the measured positional deviation amount is numerically input as a correction amount, and the conveyance amount of the photographic film is corrected by the input correction amount.

[0025]
Next, the negative carrier 30 will be described. As shown in FIGS. 3 and 4, a cover 112 that can be opened and closed with respect to the base 31 is attached to the negative carrier 30. A negative film passage portion 30A is formed in the base 31, and a mask (also referred to as an under negative mask) 118 is attached to the vicinity of the central portion (exposure position) of the negative film passage portion 30A corresponding to the rectangular through hole. It has been.
[0026]
On the other hand, in the vicinity of the rotation axis of the cover 112, a holder 114 that is rotatably attached to the base 31 similarly to the cover 112 is provided, and a crimping plate (also referred to as an upper negative mask) 116 is attached. The mask 118 and the pressure plate 116 are formed with a window 119A and a window 119B as openings corresponding to the image frames. The above-described exposure light is applied to the masks 116 and 118 and passes through the window portion 119A and the window portion 119B.
[0027]
The upper negative mask 116 is arranged with a gap that allows the negative film N to be conveyed with respect to the under negative mask 118 when the cover 112 is closed. In this state, the solenoid 117 is energized. As a result, the upper negative mask 116 is moved in a direction approaching the under negative mask 118 by the magnetic force of the solenoid 117, and the negative film N is clamped at a predetermined clamping pressure.
[0028]
Three drive rollers 132, 134, and 136 are rotatably supported and arranged upstream of the mask 118 in the negative film passage portion 30A in the negative film conveyance direction. A driving roller 138 is rotatably disposed downstream of the mask 118 in the negative film conveyance direction. As shown in FIG. 4, the negative carrier 30 includes a motor 152, and a timing belt 156 is wound around a drive shaft of the motor 152 via a pulley 154. The timing belt 156 is also wound around a pulley 140C attached to the driving rollers 132, 134, 136, and 138, and the driving rollers 132, 134, 136, and 138 are rotated by the driving force of the motor 152. .
[0029]
Driven rollers 142, 144, 146, and 148 are rotatably attached to the cover 112 so as to correspond to the drive rollers 132, 134, 136, and 138. When the cover 112 is closed, the negative film N is The drive rollers 132, 134, 136, and 138 and the driven rollers 142, 144, 146, and 148 are sandwiched. As a result, the negative film N is conveyed along the negative film passage portion 30A.
[0030]
As shown in FIG. 3, an optical sensor 172 for detecting the leading edge and the trailing edge of the negative film N is disposed upstream of the driving roller 132 in the negative film passage portion 30A in the negative film conveyance direction. In addition, a splice sensor 174 for detecting a splicing tape used when a plurality of negative films N are vertically connected to form one negative film is disposed between the drive rollers 132 and 134. Yes. A screen detection sensor 176 is disposed downstream of the splice sensor 174 in the negative film conveyance direction.
[0031]
These sensors 172, 174 and 176 are connected to the controller 182 together with the motor 152 described above. The controller 182 includes a CPU 182A, a ROM 182B, a RAM 182C, an input port 182D, and an output port 182E, which are connected to each other via a bus 182F. The aforementioned sensors 172, 174, 176 are connected to the input port 182D, and the motor 152 is connected to the output port 182E via the driver 184A.
[0032]
A keyboard 186 for giving various instructions by the operator is connected to the input port 182D. The keyboard 186 includes a left movement key 186A for instructing the movement of the image on the negative film N displayed on the monitor 32 in the left direction, a right movement key 186B for instructing a movement in the right direction, An adjustment end key 186C for instructing the end of image position adjustment, a numeric keypad 186D for inputting various numerical information, and other keys are provided. Further, the photometry unit 40 is connected to the input port 182D, and the monitor 32 is connected to the output port 182E via the driver 184B.
[0033]
Next, as an operation according to the present embodiment, an overall processing flow of the printer processor 10 will be described first. When the negative film N is inserted into the negative film transport unit 30A of the negative carrier 30 and the leading end of the negative film N is detected by the optical sensor 172, the motor 152 starts driving, and the driving rollers 132, 134, 136, 138 is rotated. At this time, since the negative film N is sandwiched between the driven rollers 142, 144, 146, and 148, the negative film N is conveyed along the film passage portion 30A.
[0034]
Next, when the image recorded on the negative film N is positioned at the exposure position based on the correction amount set by the correction amount setting process described later, the exposure light from the light source device 96 is applied to the positioned image. Then, the light that has passed through the image is irradiated onto the photographic paper P that has been previously positioned on the support base 46, so that the image is baked and exposed on the photographic paper P. When the printing exposure is completed, the negative film N is conveyed by one frame and the next printing paper P is positioned on the support base 46, whereby the printing process is repeated.
[0035]
The photographic paper P subjected to printing exposure passes through the conveyance path 60 and is sent to the processor unit 72. First, the photographic paper P is conveyed in a substantially U-shape in the color developing tank 74 and subjected to color development processing, and then bleach-fixing tank 76. The inside of the washing tank 78 is conveyed in a substantially U shape, bleached and fixed, washed with water, and conveyed to the drying unit 80. The photographic paper P discharged from the drying unit 80 is sandwiched between a plurality of pairs of rollers, discharged to the outside of the printer processor 10, and stacked.
[0036]
Next, the correction amount setting processing for the conveyance amount of the negative film N by the controller 182 will be described with reference to the flowchart of FIG. In step 200, it is determined whether or not the negative film N has been set on the negative carrier 30. After the negative film N is inserted into the negative film transport section 30A of the negative carrier 30 and the leading end of the negative film N is detected by the optical sensor 172, the motor 152 is slightly driven, and the negative roller N is interposed between the driving roller 132 and the driven roller 142. When the leading end of the film N is sandwiched, the determination in step 200 is affirmed.
[0037]
If the determination in step 200 is affirmed, in the next step 202, the driving of the motor 152 is continued and the negative film N is conveyed in the forward direction.
[0038]
When conveyance of the negative film N is started, in step 204, the screen detection sensor 176 waits for detection of the edge on the front side in the negative film conveyance direction of the image recorded on the negative film N. In the negative film, generally, the density of the portion where the image is exposed and recorded is clearly higher than the density of the unexposed portion (unexposed portion), so the density of the negative film N detected by the screen detection sensor 176 is rapidly increased. This can be detected as the front edge of the image.
[0039]
If the determination in step 204 is affirmative, after the edge of the image is detected in step 206, the negative film N is removed by a fixed amount MF (an image in which the front edge is located at the screen detection sensor 176 placement site). It is determined whether or not it has been transported by a transport amount for positioning to a predetermined exposure position.
[0040]
If the predetermined amount MF is transported after detecting the front edge of the image, it is determined that the image has reached the exposure position, and the transport of the negative film N is stopped at step 208.
[0041]
When the conveyance of the negative film N is stopped, in step 210, as shown in FIG. 6A, the negative film positioned at the exposure position based on the imaging data sequentially input from the CCD image sensor of the photometry unit 40. Display of the N image 122 and the positive image of the window 119A of the mask 118 on the monitor 32 is started. At this time, the portion of the window portion 119A is masked during normal image printing, and the aperture ratio of the gray frame that displays only the image to be printed on the monitor 32 is made larger than 100%. 119A is also displayed.
[0042]
Since the distance from the screen detection sensor 176 to the exposure position varies depending on the individual negative carrier, as shown in FIG. 6A as an example, the image 122 is located at the center in the horizontal direction of the window 119A. However, there may be a negative film N base 123 having a different width between the outer left and right ends of the image 122 and the window 119A. Hereinafter, a case where the negative film N is positioned as shown in FIG. 6A by the conveyance of the negative film N until the determination in step 206 is positive will be described as an example. Thereafter, based on the imaging data sequentially input from the CCD image sensor of the photometry unit 40, the image 122 and the positive image of the window portion 119A are displayed on the monitor 32 in real time. Therefore, the operator can check the state of the image 122 and the window 119A at the reference time by referring to the monitor 32. This step 210 corresponds to the imaging display control means of the present invention.
[0043]
In the next step 214, the operator waits for input of any one of the left movement key 186A, the right movement key 186B, and the adjustment end key 186C on the keyboard 186. At this time, the operator refers to the monitor 32, and when the left end of the image 122 is located on the right side of the left end of the window portion 119A, the left move key 186A is displayed. If they substantially match, the adjustment end key 186C is pressed. The controller 182 monitors the pressed state of the keyboard 186, and the determination in step 214 is affirmed only when the pressed key is one of the left movement key 186A, the right movement key 186B, and the adjustment end key 186C. The process proceeds to step 216.
[0044]
In the next step 216, it is determined whether or not the key pressed in step 214 is the adjustment end key 186C. If the key is not the adjustment end key 186C, one of the left movement key 186A and the right movement key 186B is determined. The process proceeds to step 218.
[0045]
In step 218, if the key pressed in step 214 is the left movement key 186A, the motor 152 is driven and pressed so that the image 122 displayed on the monitor 32 moves to the left by a predetermined amount MX. When the key thus moved is the right movement key 186B, the motor 152 is driven so that the image 122 displayed on the monitor 32 moves rightward by a predetermined amount MX. At this time, every time the controller 182 moves the negative film N to the left by a predetermined amount MX, the controller 182 counts down a counter (not shown) that is cleared in advance by the number of pulses of the drive signal of the motor 152 required for the movement. Each time a predetermined amount MX is moved in the right direction, the counter is counted up by the number of pulses of the drive signal of the motor 152 required for the movement. Therefore, the value of the counter increases or decreases in conjunction with the movement of the image 122. The predetermined amount MX when moving the image 122 is a minimum distance at which the movement of the image 122 displayed on the monitor 32 can be visually confirmed by the operator.
[0046]
On the other hand, if the key input at step 214 is the adjustment end key 186C, the left end of the image 122 is substantially coincident with the left end of the window portion 119A. At this time, the determination at step 216 is affirmed and the routine proceeds to step 220. Then, the transport amount LM (see FIG. 6B) of the image 122 when the left end position L1 of the image 122 at the time of positioning in step 208 moves to the left end position L1 ′ of the current image 122 is determined in the RAM 182C. Store in the area. The transport amount LM at this time is obtained by multiplying the counter value (number of pulses of the drive signal of the motor 152) increased or decreased in conjunction with the movement of the image 122 in step 218 by the transport distance in unit pulses. be able to.
[0047]
When the transport amount LM is stored, in the next step 222, the operator waits for input of any one of the left movement key 186A, the right movement key 186B, and the adjustment end key 186C of the keyboard 186. At this time, the operator refers to the monitor 32, and when the right end of the image 122 is located on the right side of the right end of the window portion 119A, the operator moves the left move key 186A, and when located on the left side, the right move key 186B. If they substantially match, the adjustment end key 186C is pressed. The controller 182 monitors the pressed state of the keyboard 186, and the determination in step 222 is affirmed only when the pressed key is one of the left movement key 186A, the right movement key 186B, and the adjustment end key 186C. The process proceeds to step 224.
[0048]
In the next step 224, it is determined whether or not the key pressed in step 222 is the adjustment end key 186C. If the key is not the adjustment end key 186C, one of the left movement key 186A and the right movement key 186B is determined. The process proceeds to step 226.
[0049]
In step 226, if the key pressed in step 222 is the left movement key 186A, the motor 152 is driven and pressed so that the image 122 displayed on the monitor 32 moves to the left by a predetermined amount MX. When the key thus moved is the right movement key 186B, the motor 152 is driven so that the image 122 displayed on the monitor 32 moves rightward by a predetermined amount MX. At this time, every time the controller 182 moves the negative film N to the left by a predetermined amount MX, the controller 182 counts down a counter (not shown) that is cleared in advance by the number of pulses of the drive signal of the motor 152 required for the movement. Each time a predetermined amount MX is moved in the right direction, the counter is counted up by the number of pulses of the drive signal of the motor 152 required for the movement. Therefore, the value of the counter increases or decreases in conjunction with the movement of the image 122.
[0050]
On the other hand, when the key input in step 222 is the adjustment end key 186C, the right end of the image 122 substantially coincides with the right end of the window portion 119A. At this time, the determination in step 224 is affirmed and the routine proceeds to step 228. Then, the transport amount RM of the image 122 (see FIG. 6 (FIG. 6) when the right end position R1 (see FIG. 6A) of the image 122 at the time of positioning in step 208 moves to the right end position R1 ′ of the current image 122. C) is stored in a predetermined area of the RAM 182C.
[0051]
The transport amount RM at this time is obtained by multiplying the counter value (number of pulses of the drive signal of the motor 152) increased or decreased in conjunction with the movement of the image 122 in step 226 by the transport distance in unit pulses. It can be obtained by subtracting the carry amount LM from the obtained value (the carry amount from the position of the image 122 in a state in which the left end of the image 122 is aligned with the left end of the window portion 119A). Note that steps 214 to 218 and steps 222 to 226 described above correspond to the adjusting means of the present invention.
[0052]
In the next step 230, the correction amount of the conveyance amount at the time of a certain amount MF conveyance of the negative film N by the negative carrier 30 is calculated. At this time, first, the center position C of the image 122 after the conveyance amount correction is obtained using the equation (1), and then the conveyance amount correction amount Adj is derived using the equation (2) (see FIG. 6C). ).
[0053]
C = {(C0 + LM) + (C0 + RM)} / 2 (1)
Adj = C0-C (2)
Here, LM is the transport amount stored in step 220, RM is the transport amount stored in step 228, and C0 is the image 122 when the negative film N is transported and positioned by a predetermined amount MF in steps 204 to 208. Center position (see also FIG. 6A). The center position C0 can be obtained as a distance from the position where the screen detection sensor 176 is disposed by subtracting half the length in the transport direction of the image 122 from the fixed amount MF in step 206, and is stored in the ROM 182B. It is stored in advance.
[0054]
Since the center position C obtained by the equation (1) is a position substantially coincident with the center position of the window portion 119A, the correction amount Adj obtained by the equation (2) is positioned by carrying a certain amount MF of the negative carrier 30. The difference between the center position C0 of the image 122 and the center position C of the window portion 119A of the actual mask 118 is obtained. This step 230 corresponds to the carry amount determining means of the present invention.
[0055]

In this embodiment, the case where the size of the window portion 119A is larger than the size of the image 122 has been described. However, the present invention is not limited to this, and the size of the window portion 119A is larger than the size of the image 122. The present invention can also be applied to a small case. In this case, the image printed on the photographic paper P is not the entire image 122 but a predetermined area in the central portion.
[0062]
In the present embodiment, the case where it is finally determined whether or not to correct the conveyance amount of the negative film N based on the judgment of the operator has been described. However, the present invention is not limited to this. Further, the conveyance amount may be automatically corrected without making a determination by the operator.
[0063]
Moreover, although this Embodiment demonstrated the case where a film was a negative film, this invention is not limited to this, A positive film may be sufficient.
[0064]
Furthermore, in the present embodiment, the case where only the image 122, the window portion 119A, and the correction amount Adj are displayed on the monitor 32 has been described. However, the present invention is not limited to this, and for example, as shown in FIG. Various information may be displayed in the empty area of the monitor 32. As shown in the figure, the work content display unit 100 displays the operator's work content, and the work procedure display unit 102 displays the operator's work procedure. Thus, when the work content and work procedure are displayed as various information on the monitor 32, the work to be performed by the operator can be clarified, so that the work time can be shortened and erroneous work can be prevented. Can do.
