Abstract

PURPOSE:To display a concerned frame number regardless of a way specified by a customer and to improve workability. CONSTITUTION:The areas of the respective frame numbers are divided into four and an overlapped area 285 is set by both end areas corresponding to adjacent image frames. Since the frame number is added to the image frame of full size by the image frame pitch of half size, there is a case that two frame numbers correspond to the image frame of the full size. In the case that the central line (an alternate long and short dash line L in a figure 7) of the image frame 16A belongs to the area 285, two frame numbers are displayed together on a display part 185. Thereafter, such failure that the frame number which is ordered and requested is not displayed is eliminated and it is good that the customer optionally selects either as in the conventional manner. Besides, the need of work that an operator takes out a negative film 16 and retrieves the ordered frame number in the case that the concerned frame number is not displayed is eliminated and working efficiency is improved.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention provides an image frame number display method for displaying a frame number assigned to each image frame, and a method for positioning a corresponding image frame to a printing position based on a designated frame number. The present invention relates to a photographic printing apparatus that performs printing processing.

2. Description of the Related Art In a photographic printing apparatus, a negative carrier is installed at a printing position in order to sequentially position developed negative films at the printing position. The negative carrier is composed of a base and a lid that can be opened and closed with respect to the base, and the base is formed with a negative film guide path in which printing openings are provided corresponding to image frames. In the guide path, rollers that are rotationally driven by the driving force of a pulse motor are arranged near both ends of the negative film in the width direction. Further, an idle roller is attached to the lid body to form a pair with these rollers and to sandwich the negative film. Therefore, when the lid is closed and the negative film is inserted from the side of the negative carrier, the negative film can be held and conveyed along the guide path.

[0003] A detection device for detecting an image frame edge is provided on the upstream side of the printing opening in the guide path. Generally, the base portion of a negative film has a low density, and the density within the image frame range is high. The image frame edge is detected from this density difference and positioned to the printing position.

By the way, in the case of reprinting, unlike simultaneous printing, only designated image frames are printed. This designation is made by frame number. The frame number is recorded on the edge of the negative film in the width direction using both numbers and a bar code, and the customer visually checks the number when making a request. The printing device reads and displays the barcode when the negative film is transported. The operator checks the displayed content, compares it with the requested frame number, positions the image frame corresponding to the frame number that matches as a result of the comparison to the printing position, and performs the printing process. Thereby, reprint processing can be performed smoothly.

[0005]

[Problem to be Solved by the Invention] However, the relative positions of the image frames recorded on the negative film and the frame numbers (numbers and barcodes) given to the ends of the negative film in the width direction are determined by the loading state in the camera. It changes with In addition, the frame numbers are assigned numbers with the code "A" appended to the end of adjacent numbers between consecutive numbers so as to be compatible with half size. i.e. 1, 1A, 2, 2A
, 3, 3A, . . . are given at a half-size image frame pitch, so two frame numbers correspond to a full-size image frame. Generally, in printing equipment,
The frame number closer to the center line of the image frame is displayed as the corresponding frame number.

However, the customer does not necessarily request the frame number closest to the center line of the image frame. For example, if frames 2 and 2A correspond to the image frames for which you are requesting reprints, and you specify frame number 2A, which is farther from the center line, the printing device will display only frame number 2, and the matching frame number will be displayed. cease to exist. In such a case, the operator has to take out the negative film and check the frame number with the image frame, which makes the work complicated.

[0007] In consideration of the above facts, the present invention aims to provide an image frame number display method that can display the corresponding frame number regardless of how the customer specifies it, and that can improve work efficiency. It is.

[0008] In addition to the above object, it is another object of the present invention to provide a photo printing device that can perform printing processing by automatically comparing the frame number specified by the customer with the frame number read by the device. .

[0009]

[Means for Solving the Problems] The invention as set forth in claim 1 provides a method for recording full-size image frames on a photographic film in which frame numbers are assigned at a half-size image frame pitch. A frame number display method for displaying the frame number of an image frame, in which each frame number area centered on the frame number assigned position is divided into a plurality of parts, and each divided area is adjacent to the front or rear end side area. An overlapping area of two frame numbers is set by the rear edge or front edge side area of the matching frame number, and if the center line of a full-size image frame belongs to the overlapping area, both frame numbers corresponding to this overlapping area are displayed. It is characterized by

According to the second aspect of the invention, when full-size image frames are recorded on a photographic film to which frame numbers are assigned at a half-size image frame pitch, the full-size image frames can be recorded by frame numbers. A photo printing apparatus that performs printing processing according to specifications, comprising an input means for inputting the frame number of an image frame to be printed, a frame number reading means for reading the frame number of the image frame while conveying the image frame, and a frame number reading means. Each frame number area centered at the reading position of the frame number by the means is divided into a plurality of parts, and the central area is set as an independent area belonging to a single frame number, and each divided front end or rear end side area is a setting means for setting an overlapping area belonging to two frame numbers based on the rear end or front end side area of adjacent frame numbers; The apparatus includes a collation means for collating a frame number inputted by the input means, and a positioning means for positioning an image frame whose frame number matches as a result of the collation by the collation means to a printing position.

[0011]

[Operation] According to the invention as set forth in claim 1, the relative positions of the frame number position previously assigned to the photographic film and the recording position of the image frame change depending on the loading state of the photographic film in the camera. . Usually, frame numbers are assigned at half-size image frame pitches, so two frame numbers may correspond to one full-size image frame.

[0012] The frame number that a customer selects when ordering reprints is specified by one of the frame numbers.
Which frame number is specified depends on the customer's judgment. On the other hand, on the printing device side, the area corresponding to one frame number is divided into multiple areas, and the areas on the front and rear ends,
An overlapping area is set by areas on the rear end and front end sides of adjacent frame numbers. Here, if the center line of the image frame belongs to this overlapping area, both frame numbers corresponding to the overlapping area are displayed together.

[0013] As a result, there is no problem such as the frame number specified by the customer not being displayed, and the operator can select the image frame to be printed simply by comparing the displayed frame number with the frame number requested by the customer. Can be specified.

[0014] According to the second aspect of the invention, the frame number requested by the customer is inputted by the input means. On the other hand, on the apparatus side, the area of the frame number read by the frame number reading means is set by the setting means, and the frame number of the image frame is determined based on the area to which the center line of the image frame belongs. Next, it is determined whether the frame number determined by the matching means matches the input frame number, and if they match, the corresponding image frame is positioned at the printing position by the positioning means.

[0015] Since the overlapping area is provided, there is no possibility that the frame number inputted by the input means is absent, and the image frame corresponding to the inputted frame number can be reliably positioned at the printing position, thereby increasing the reprinting processing efficiency. can be improved.

The photographic paper 54 is held between a pair of rollers 82A, and the photographic paper 54 that has been dried is discharged from the drying section 80 at a constant speed. A pair of rollers 82B are disposed above the rollers 82A, and are intermittently rotated in response to processing by a cutter section 84 disposed downstream of the drying section 80. As a result, the cutter section 84 cuts the photographic paper 54.
It is composed of a cut mark sensor 86 that detects a cut mark given to a cut mark, and a cutter 88 that cuts the photographic paper 54, cuts the photographic paper 54 image by frame, and discharges the photographic paper 54 to the outside of the casing 12 of the printer processor 10.

The frame number read by 82 is displayed.

FIG. 4 shows a negative carrier 18 according to this embodiment.
It is shown. This negative carrier 18 is constructed mainly of a pedestal 200 as a base and an open/close cover 202 as a lid.

A negative film transport path 204 is formed in the pedestal 200 as a guide path. A printing opening 206 is provided at the center in the longitudinal direction of the negative film transport path 204, and serves as an irradiation opening for light from a light source 38 provided in the printer processor 10.

The size of the printing opening 206 is the same as the full-size image frame 16A of the negative film 16. In the negative film transport path 204, transport rollers 208, 210, and 212 are provided on the upstream side (to the left in FIG. 4) and the downstream side (to the right in FIG. 4) of the printing opening 206, corresponding to the back surface (lower surface) of the negative film 16. It is arranged as follows. As shown in FIG. 5, each conveyance roller 208, 210, 21
2, 213 has a sprocket 214 attached to one axial end of its rotating shaft, and an endless timing belt 216.
It meshes with the teeth formed on the

The timing belt 216 is wound around a sprocket 214 attached to the most upstream conveyance roller 208 and a sprocket 214 attached to the rotating shaft of a pulse motor 218. The pulse motor 218 is connected to the driver 2 to the control device 220 (see FIG. 8).
22 and is configured to be driven in steps in response to a drive signal from a control device 220. Accordingly, when the pulse motor 218 rotates, each of the conveyance rollers 208, 210, 212, and 213 is driven in the same rotation direction and at the same rotation speed.

The opening/closing cover 202 has a housing-like cover main body 224 whose lower end is pivotally supported by a bar 226 fixed to the pedestal 200, and can be opened and closed with respect to the pedestal 200 around this bar 226. ing.

A through hole 228 corresponding to the burning opening 206 is provided at the bottom of the cover body 224. The cover body 224 also has an upper guide base 230 at a position corresponding to the negative film transport path 204 in the closed state.
is attached, and a negative film guide wall 232 is integrally formed so that a gap is created between the tip of the negative film guide wall 232 and the bottom surface of the negative film transport path 204. Further, this gap size is slightly larger than the wall thickness of the negative film 16 to ensure a conveyance path for the ends in the width direction of the negative film.

Furthermore, the conveying rollers 208, 210, 212 and 21 are provided between the guide walls 232.
3, idle rollers 234, 236, 238
and 239, and when the opening/closing cover 202 is closed, the idle rollers 234, 23
6, 238 and 239 and conveyance rollers 208, 210, 2
12 and 213 sandwich the negative film 16, so that conveyance force can be transmitted to the negative film 16.

An upper mask 240 is disposed at the center of the upper guide base 230 in the negative film transport direction, and is movable relative to the upper guide base 230 and has an opening at a position corresponding to the through hole 228. . Upper mask 240 is detachably attached to mask base 242.

[0039] The mask base 242 has a cover main body 224.
The solenoid main body 250 is supported via a shaft near the rotation center of the solenoid main body 250 when the cover main body 224 is closed. When the solenoid main body 250 is energized, the mask base 242 is attracted by magnetic force, and the upper mask 240 can be brought into close contact with the printing opening 206 of the negative film transport path 204, thereby sandwiching the negative film 16 positioned on the optical axis P. It is now possible to do so.

As shown in FIG. 6, a rectangular groove 252 is formed in the bottom of the negative film transport path 204 on the upstream side of the printing opening 206, and a transparent glass plate 254 is fitted into the bottom surface of the negative film conveying path 204. It is said to be the same. This groove 252
A slit hole 256 that penetrates to the back surface of the negative film transport path 204 is formed at the bottom of the negative film transport path 204 . Slit hole 25
The longitudinal direction of 6 is provided along the width direction of the negative film transport path 204. On the back side of the negative film transport path 204 corresponding to this slit hole 256, a light emitting diode (hereinafter referred to as an LED chip) 258 serving as a light projecting section is installed in the width direction of the negative film transport path 204, that is, in the width direction of the negative film 16. Multiple pieces are arranged along the

The slit hole 256 corresponds to the screen detection sensor 264 provided on the upper guide base 230 of the cover body 224 when the cover body 224 is closed. Therefore, the amount of light transmitted through the negative film 16 is detected by the screen detection sensor 264. Four screen detection sensors 264 are arranged along the width direction of the negative film 16 and are connected to the control device 220. The control device 220 obtains the photographic film transmission density distribution based on the output signal from the screen detection sensor 264, and detects the boundary between the image frame 16A and the base portion, that is, the image frame edge.

The bottom surface of the negative film conveyance path 204 on the upstream side of the slit hole 256 is slightly deeper in the center so that it does not come into contact with the negative film 16 when the negative film 16 is conveyed. That is, since only both ends of the negative film 16 in the width direction are in contact with each other, the image surface is not damaged. In this deep bottom surface, two circular holes 266 and 268 are provided along the longitudinal direction at the center in the width direction of the negative film transport path 204, and the LED elements 27
0 and 272 are buried respectively. These LEDs
The elements 270 and 272 are each connected to the control device 220 and emit light in response to a signal from the control device 220.

LED element 270 near slit hole 256
is used to detect the splice tape used for joining when a plurality of negative films 16 are connected to form a roll, or the management tape affixed to each negative film 16, and is used to detect the negative film insertion in the negative film transport path 204. The LED element 272 on the opening side is used to detect the presence or absence of the negative film 16, and corresponds to a tape sensor 274 and a negative presence/absence sensor 276, respectively, which are attached to the upper guide base 230 side. The tape sensor 274 and the negative presence/absence sensor 276 are each connected to the control device 220.

[0044] The LED element 270 and the LED element 272
LED elements 280 are embedded in both widthwise ends of the negative film transport path 204 between the negative film transport path 204 and the negative film transport path 204 . This LE
The D element 280 is connected to the control device 220 and corresponds to barcode sensors 282 provided at both ends of the upper guide base 230 in the width direction. Barcode sensor 282
is connected to the control device 220. Negative film 1
The barcode 283 given to 6 is an encoded representation of the ID and the frame number given corresponding to each image frame 16A. The frame number and the frame number barcode 283 are each assigned at a half-size image frame pitch. That is, as shown in FIG.
Two frame numbers (
For example, image frame B has "21" as the frame number.
21A”) is supported.

Here, in the control device 220, each frame number area is divided into four areas to provide four areas. An overlapping region 285 is set in the regions at both ends, with regions at both ends corresponding to adjacent image frames, respectively. In other words, each area has an area enlarged by 1/4 on the left and right sides.

In the case of reprint processing, the control device 220 uses the area to which the center line of the image frame 16A (for example, the dashed line L for image frame B) belongs as the frame number of this image frame 16A, and displays it on the display section 185. However, if the center line belongs to the overlapping area, two frame numbers are displayed together (for image frame B, frame numbers "21" and "21A").

The operator compares the displayed frame number with the frame number requested for reprinting, and if they match, instructs the printing process.

Note that the barcode 283 is the LED element 2
80, detected by the barcode sensor 282, and decoded by the control device 220.

The barcode sensor 282 is attached to a frame member 284 that is swingable with respect to the upper guide base 230, so that it can follow the meandering movement of the negative film 16 during transportation. Therefore, the barcode attached to the narrow end portion of the negative film 16 in the width direction can be read regardless of the meandering of the negative film 16.

As shown in FIG. 8, the control device 220
It includes a CPU 286, a RAM 288, a ROM 290, an input port 292, an output port 294, and a bus 296. The output port 294 is connected to the pulse motor 218 via the driver 222 and the solenoid body 250 via the driver 298, respectively.

[0051] Also, each output port 294 has an L

screen detection sensors 264 are connected to amplifiers 306 and A, respectively.
/D converter 308. Furthermore, the input port 292 has four key switches 310A, 310B, 3 provided on the pedestal 200 of the negative carrier 18.
10C and 310D are connected. By operating this key, the stop position of the negative film 16 can be forwarded, reversed, and finely adjusted.

This control device 220 is connected to the controller 162 on the printer processor 10 side.

The operation of this embodiment will be explained below. first,
The normal printing process procedure will be explained.

[0055] When the process is started, the light source 38 is turned on,
The negative carrier 18 is driven to position the negative film 16. The L of the negative film 16 is determined by the density measuring device 56.
The ATD (average transmission density) is measured, an exposure correction value is set from this measurement data and data manually input by key, and the exposure amount (exposure time) is calculated to obtain optimal printing conditions.

Next, the photographic paper 54 is transported to the exposure chamber 52 and positioned, and the shutter 50 is opened. This results in
The light beam emitted by the light source 38 passes through the filter unit 40 and the negative film 16 and reaches the exposure chamber 52, and the photographic paper 54 positioned in the exposure chamber 52 starts printing an image on the negative film 16 according to the exposure conditions. The C, M, and Y filters located on the optical axis of the light beam are moved. After the predetermined exposure time has elapsed, the shutter 50 is closed. With this, the printing process for one frame of the negative film 16 is completed. By repeating this, the printed portions of the photographic paper 54 are sequentially conveyed to the reservoir section 18.

The photographic paper 54 conveyed to the reservoir section 70 is conveyed to the color developing section 74, where it is immersed in a developer and subjected to development processing. The developed photographic paper 54 is transferred to a bleach-fixing section 76.
The image is transported to and subjected to fixing processing. Photographic paper 54 that has been fixed
is transported to the rinsing section 78 and washed with water. The photographic paper 54 that has been washed with water is conveyed to a drying section 80 and is dried.

The photographic paper 54 that has been dried is transferred to the cutter section 8.
A cut mark is detected in step 4, and each image is cut.

In this embodiment, the negative carrier 18 automatically positions each image frame 16A (16B) of the negative film 16 to the printing position, and the screen detection sensor 264 detects the edge of each image frame. Then, conveyance control is performed by making this image frame edge correspond to the number of feed pulses of the pulse motor 218.

The image frame positioning procedure will be explained below with reference to the flowchart shown in FIG. First, in step 400, the negative film 1 is detected by the negative presence/absence sensor 276.
6 is inserted into the negative carrier 18, and if the determination is negative, the process moves to step 402 and the LED chip 258 is turned off. If the determination is affirmative, the process moves to step 404 and the LED chip 258 is
lights up.

In the next step 406, the negative film 1
When it is determined that the conveyance for positioning the slit hole 2 to the printing position has started, the process moves to step 408 and the slit hole 2 is moved to the printing position.
56 and the amount of transmitted light transmitted through the negative film 16 is detected, and then A/D conversion is performed in step 410.
Each piece of data is stored in correspondence with the number of sending pulses (step 412).

The steps 408, 410, and 41 are repeated until it is determined in the next step 414 that the conveyance has been stopped.
2 is repeated, and when it is determined in step 414 that the conveyance has been stopped, the process proceeds to step 416, where a transmission density distribution for one conveyance is created based on the stored data. Next, in step 418, a maximum point (maximum density value) is selected from the created transmission density distribution, and the number of sending pulses PMAX corresponding to this maximum point is set. In the next step 420, the number of sending pulses PA' for the density value that is 92% of the maximum point is determined and set as a temporary edge.Next, in step 422, a predetermined number of pulses (12 pulses in this embodiment) is set from this temporary edge PA'. The minimum point (minimum density value) within the range is selected, and the number of sending pulses PMIN corresponding to this minimum point is set. In the next step 424, the position of 50% of the maximum point feed pulse PMAX and the minimum point feed pulse PMIN, that is, (PMAX
+PMIN)/2 is calculated and image frame 16A (16B
) is determined.

The image frame edge pulse PA determined in this manner applies not only to the normally exposed negative film 16 but also to the normal exposure negative film 16.
Even with respect to underexposed or overexposed negative film 16, the position is approximately constant, and detection errors can be suppressed within a range that does not impede positioning.

In the next step 426, it is determined whether or not there is a positioning instruction from the controller 262 of the printer processor 10, and if it is determined that there is an instruction,
The process moves to step 428 to read the current number of feed pulses PX, and then, in step 430, the feed amount PDRIVE is calculated from this current feed pulse PX and the number of image frame edge pulses PA (PDRIVE=PA).
-PX).

In the next step 432, the negative film is transported by the calculated transport amount PDRIVE. This conveyance is determined to be the conveyance in step 406. That is, during conveyance for positioning, the edge of the image frame 16A (16B) two frames before is detected on the upstream side.

When the predetermined image frame 16A (16B) is positioned at the printing position, a positioning completion signal is output to the controller 162 of the printer processor 10 in step 434, and in response, the printer processor 10 performs the above-mentioned process. A baking process is performed.

In the next step 436, it is determined whether or not there has been an instruction to end the burning process. If the determination is negative, the process continues and the process moves to step 400; if the determination is affirmative, the process moves to step 438. LED chip 258
Turn off the light and exit.

The above is the normal printing process, and in the case of simultaneous printing, the printing process can be performed by sequentially positioning the image frames to the printing position.

By the way, when there is an order for reprinting, only the ordered image frames are searched and printed, but this reprint order is specified by the customer using the frame number attached to the negative film 16. It looks like this.

Therefore, the operator compares the frame number read when the negative film 16 is conveyed and displayed on the display section 185 with the frame number written on the order sheet, etc., and instructs the printing process only for those that match. .

Here, since the frame numbers are assigned at half-size image frame pitches, two frame numbers may correspond to a full-size image frame. The customer arbitrarily selects one of these two frame numbers and specifies it at the time of ordering. On the other hand, in the printer processor 10,
Conventionally, the frame number closest to the center line of the image frame was selected and displayed on the display section 185, so if the customer selected a frame number that was not selected by the device, the corresponding frame number would be displayed on the display section 185. In some cases, the number was not displayed. However, in this embodiment, the area of each frame number is expanded left and right,
An overlapping area 285 that overlaps with the adjacent frame number area is provided, and if the center line of the image frame 16A (in image frame B in FIG. 7, the dashed line L) belongs to this overlapping area, the two frame numbers are written together. (In image frame B in FIG. 7, the displayed frame number is "21").
” and “21A”).

[0072] Therefore, there is no problem such as the frame number for which an order has been requested not being displayed, and the customer can simply select one of them arbitrarily as before. Also, if the corresponding frame number is not displayed, the operator can
This eliminates the need to retrieve the ordered frame number and search for the ordered frame number, improving work efficiency.

In this embodiment, the image frame to be printed is specified by displaying the read frame number on the display section 185 and comparing the displayed content with the ordered frame number. As described above, by providing the overlapping area 285, it is possible to eliminate the possibility that a corresponding frame number does not exist. Therefore, the matching operation may be automated, the corresponding image frame may be positioned at the printing position, and the printing process may be performed. That is, before detecting the frame edge, the frame number may be read, and the frame edge of only the corresponding image frame may be detected and positioned. The image frame positioning and printing process is
Since the simultaneous printing process described above is the same, the explanation will be omitted.

Further, in this embodiment, the frame number area is divided into four, but the number of divisions is not limited.

Furthermore, when printing frame numbers on the back side of photographic paper during simultaneous printing, if you print only the frame number closest to the center line of the image frame as before, the customer will not be able to see the back side of the photographic paper. If you order additional prints, there is no need to apply this example and the frame numbers will match, but if the machines used for simultaneous printing and those used for printing the reprint order are different, in rare cases the printed frame numbers may not be read. There may be no. Even in such a case, in this embodiment, the requested frame number is reliably displayed. In other words, the effects of the present invention are most noticeable when the user specifies the frame number of the image frame to be reprinted while looking at the negative film 16.

[0076]

Effects of the Invention As explained above, the image frame number display method according to the present invention has the advantage of being able to display the corresponding frame number regardless of how the customer specifies it, thereby improving work efficiency. It has a great effect.

In addition to the above effects, the photo printing apparatus according to the present invention can automatically compare the frame number specified by the customer with the frame number read by the apparatus and perform the printing process. Has excellent effects.
