Abstract

PROBLEM TO BE SOLVED: To correct synchronism between detected results even in the case of deciding that the collated results are not coincident concerning the kinds of the punched holes by executing succeeding processing after adopting the kind of the holes whose set priority is high when the kinds of the holes actually detected are not coincident. SOLUTION: A punching means 63 provided at a main printing part 13 forms the hole by every length obtained by adding length of a small margin to length equivalent to one photographic print by punching the paper 21 in the longitudinal direction of the paper. Detection means 61 provided in a back printing part 42 and an index printing part 44 detect the kind of the formed hole respectively. Furthermore, the kinds of the holes in storing order are inputted from a memory 62, and then coincidence or non-coincidence concerning them is decided by a control means 64. As a result, when they are not coincident, the succeeding processing is executed based on the kind of the hole selected by the control means 64.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic printing apparatus, and more particularly, to exposing an image on the surface of paper (photographic paper), and printing image accompanying information such as a frame number mainly on the back of the paper. The present invention relates to a photographic printing apparatus capable of printing an index image for an index.

[0002]

2. Description of the Related Art In large-scale developing laboratories, in order to carry out photographic printing efficiently, a large number of photographic films are connected to form a single film, which is wound into a roll for convenience of handling. Then, the film is handled in a roll form, developed by a film processor, and then subjected to a film test. Based on the result of the film test, printing is performed by a photographic printing apparatus (auto printer).

[0003] This photographic printing apparatus is disclosed, for example, in Japanese Patent Application Laid-Open No. 7-5585.
As disclosed in Japanese Patent Application Laid-Open No. H10-260, an exposure unit for exposing and printing an image recorded on each frame of the film in the form of a roll is provided on a long piece of paper wound in a roll form. In order to satisfactorily wind the paper that is intermittently fed in the exposure unit in the winding unit, a paper storage unit (buffer unit, buffering unit) is provided between the exposure unit and the paper winding unit. (Sometimes referred to as a reservoir section). As a result, the paper portion passing through the exposure unit is intermittently fed as in the related art, while the paper winding unit can continuously and satisfactorily wind the paper at a constant speed.

In addition to the above, the photographic printing apparatus is provided with a printing unit for printing incidental information (for example, frame number for each film) corresponding to an image to be exposed on paper and exposure conditions at the time of exposure. Is common. The printing unit is configured such that, for example, as shown in FIG. 7A, a print head is arranged in parallel with an exposure unit, and the exposure of one frame of image onto the front surface of paper is performed. When the paper is fed to the paper take-up unit for one frame for the exposure of the next frame after the completion of the printing, the print head prints the frame number etc. on the back area corresponding to the area of the paper on which the image was exposed and recorded. Is recorded (see FIG. 7 (2)).
The timing of this printing is controlled by the control means.

However, in the relationship between the exposure section and the printing section, it is necessary to perform printing within a short time in which paper is intermittently fed, so that a sufficient amount of printing cannot be ensured and the printing quality is improved. Is also difficult.

In particular, a photographic system of a new standard called a so-called advanced photo system (APS) has a particularly large influence. That is, in this new standard system, data relating to shooting conditions set on the camera side, such as exposure during shooting, shutter speed, and whether or not a strobe is used, are recorded in the magnetic recording band of the APS film, and this data is used for development. In this case, the data is read out and printed on the back of the photo print to inform the user of the camera of the data so that the user can refer to the setting of the photographing conditions at the time of the next photographing. Therefore, in APS, it is necessary to increase the print amount.

Therefore, the paper storage section is provided between the exposure section and the printing section so that the exposure section performs intermittent feeding while the printing section performs printing while feeding at a constant speed, so that the exposure time and printing time are reduced. It is conceivable to secure time at the same time.

Further, in the above-mentioned APS, the developed film is stored in a conventional cartridge like a cartridge and returned to the customer. Therefore, in addition to a normal photographic print, an index for an additional order is required. It is a principle to provide a print (hereinafter referred to as IP) to a customer. This index print is obtained by reducing all the images recorded on each film and arranging them in a matrix in the order of photographing. Therefore, in order to cope with the APS, it is necessary to provide a dedicated index exposure unit for printing an index print in the above-mentioned photographic printing apparatus. By providing the index exposure section separately from the normal exposure section, it is necessary to provide a paper storage section between the printing section and the index exposure section.

[0009]

By the way, in the configuration in which the paper storage section is provided on the paper feed path as described above, the printing section only uses the feed amount in the main exposure section, which is the reference of the paper feed. It is not possible to uniquely determine the paper feed amount in the index exposure unit. For this reason, positioning for printing or index printing cannot be performed.

[0010] As a result of repeated studies, the applicant of the present invention has detected hole punches in paper formed in the main exposure section by means of hole punch detection means provided in the printing section and the index exposure section, respectively. Based on the timing, invented a photographic printing device that performs the positioning of the start position of printing in the printing unit and the index print area in the index exposure unit,
Suggest this.

However, in the proposed printing apparatus, a plurality of types of hole punches are formed in the main exposure section, and the types of the hole punches are discriminated in the printing section and the index exposure section, respectively. Since each process needs to be a reference, it is necessary to carefully determine the type.

Therefore, in the printing section and the index exposure section, the type of hole punch actually detected and
It is conceivable to determine whether or not the type of hole punch according to the order of formation in the main exposure section matches. In other words, if the two types match, it is possible to print a print content with higher accuracy, or to perform index exposure more correctly in an area where index exposure is to be performed.

However, in the photographic printing apparatus in which the control of the detection is performed as described above, the type of the hole punch actually detected in the printing unit and the index exposure unit, and the hole punch according to the order formed in the main exposure unit. May rarely match.

The present invention has been made in view of the above circumstances. As described above, even when the collation result between the actual detection result and the one based on the order in which the hole punches are formed does not match, the type of the hole punch is determined. It is an object of the present invention to provide a photographic printing apparatus capable of correcting synchronization.

[0015]

According to the photographic printing apparatus of the present invention, priorities are set in advance for the types of hole punches of the paper formed in the main exposure section, and the types of the formed hole punches and the printing section are determined. If the type of each hole punch actually detected by the index exposure unit does not match, the subsequent processing is performed after adopting the higher priority type set.

That is, the photographic printing apparatus according to the present invention comprises: a main exposure section for printing an image for each photographed frame recorded on a film onto a long paper; and reducing at least a part of an image of all photographed frames for each film. An index exposure unit for printing as an index, and a printing unit for printing incidental information for each image of each photographed frame or for each index image on a portion corresponding to each of the areas of the paper printed by these exposure units. The main exposure unit is disposed upstream of the printing unit and the index exposure unit in the paper feeding direction, and the main exposure unit exposes an image of the paper for each photographing frame. Punching means for forming a predetermined hole punch corresponding to an area or an area where the index image is exposed, wherein the printing unit and the index Scan exposure unit, the photographic printer process in which forms a corresponding to the type of the hole punch,
The printing unit and the index exposure unit each have a detection unit that detects the type of the hole punch, the type of the hole punch in the order punched by the punching unit, the printing unit and the index exposure unit Each of the detection means is compared with each detection result of the type of the hole punch, and when the comparison results do not match,
According to another feature of the present invention, there is further provided a control means for selecting one of the hole punch types according to a preset priority order between the hole punch types.

Here, the portion corresponding to each of the paper regions is, specifically, a blank portion where the image of the paper is not exposed, and the like, in addition to the blank portion on the surface where the image is exposed. Surface not exposed (back surface)
Including the whole. However, it does not include a portion that is cut for each print of each image later.

The supplementary information includes, for example, information on photographing conditions such as a shutter speed, an exposure opening value, the use of a strobe, a comment at the time of photographing, a number for specifying a customer, a film serial number, a frame number, and the like. There is information for uniquely specifying an image, and other print conditions in the main exposure section, for example.

The printing is not limited to drawing "characters" literally, but also includes drawing symbols and simple figures. This is because displaying the supplementary information as a simple symbol may make it easier for the user to recognize it.

The order of the main exposure section, the printing section, and the index exposure section on the paper feeding path may be the order of the main exposure section, the printing section, the index exposure section, or the main exposure section, the index exposure section. , The order of the printing units. In the case of the main exposure section, the printing section, and the index exposure section, it is necessary to provide a paper storage section between the main exposure section and the printing section and between the printing section and the index exposure section. In the case of an exposure section, an index exposure section, and a printing section, it is necessary to provide a paper storage section between the main exposure section and the index exposure section and between the index exposure section and the printing section.

In the case where the main exposure section and the index exposure section are intermittently fed and the printing section is continuously fed, the intermittent feeding in the main exposure section and the index exposure section is stopped. The average feed speed is obtained based on the total time of the feed time and the feed time and the feed length of one frame, and the average feed speed of the paper in these exposure units (particularly the main exposure unit) and the substantially constant paper feed speed in the printing unit It is desirable to set the feed speed to be substantially equal. In particular, the feed speed on the downstream side in the paper feed direction should not be set higher than the feed speed on the upstream side. If the margin of the paper stored in the paper storage section decreases with the elapsed time of feeding the paper, and if the margin is exhausted before the paper is completely wound on the paper winding section, excessive pulling force acts on the paper. Then, the paper may be broken.

On the other hand, the feed speed on the downstream side in the paper feed direction should not be set extremely lower than the feed speed on the upstream side. This is because the amount of paper stored in the paper storage unit increases with the elapsed time of feeding the paper, and the paper may become jammed in the storage unit due to the weight of the paper itself, making it impossible to feed the paper.

The part corresponding to the area for exposing the image for each photographed frame or the part corresponding to the area for exposing the image for indexing, in which the hole punch is formed, is mainly used for the boundary of each print, that is, for the end user. The part to be cut off when delivered.

The detecting means includes a light emitter for projecting light from one side to the other so as to sandwich a passage portion of the paper on which the hole punch to be detected is formed, and a part for which the punch hole of the paper is not formed. And a light receiver arranged to detect the light by the projector while the portion where the punched hole is passing does not detect the light by the projector while the light passes. Preferably, it is a detection means.

The detecting means and the control means may be provided separately in both the printing section and the index exposure section, and the control means may be integrated with both the printing section and the index exposure section. The configuration may be as follows.

The perforating means must form different hole punches in accordance with the type of image to be printed on each area of the paper and the section of the film to be exposed. Here, the image type refers to a single image or an index image, and a film break refers to a break after the last one (24th) of, for example, a 24-shot film. And
It is also a subject separator.

Examples of different hole punches include a combination of two holes. One hole is formed near the upper edge of the paper, and the other hole is formed near the lower edge of the paper. Immediately after one print (referred to as a general print), only the lower hole is formed. Immediately after the index print, only the upper hole is formed. Immediately after one print (regardless of whether the print is a general print or an index print), both upper and lower holes are formed.

Further, the type of the image and the division of the film may be set based on the film information obtained by reading the image recorded on the film in advance. For example, it may be read at the time of film inspection after development processing.

The main exposure section further comprises a storage means for storing the additional information of the film and / or the printing condition in the main exposure section and the hole punch for each photographing frame in a predetermined storage medium, and The part stores the additional information corresponding to the hole punch stored in the storage medium, the additional information corresponding to the hole punch detected by the detection means, and / or
Alternatively, it is desirable to print the printing conditions on paper.

The processing according to the type of hole punch performed by the printing unit and the index exposure unit means, for the printing unit, processing for printing supplementary information for general printing or index printing according to the type of hole punch, for example. For example, there is a process such as a process for printing the additional information for printing, and a process for exposing the general print or a process for exposing the index print according to the type of the hole punch for the index exposure unit.

The priority order of the hole punch types is, from the highest priority, a hole punch indicating a film break, a hole punch indicating an index image, and the like.
It is preferable to use a hole punch representing an image of a general print.

[0032]

According to the photographic printing apparatus of the present invention, priorities are set in advance for the types of the hole punches of the paper formed in the main exposure section, and the types of the formed hole punches, the printing section and the index are set. If the type of each hole punch actually detected by the exposure unit does not match, the control means performs control so as to select the type having the higher priority set. By following the type of punch, it is possible to smoothly shift to the subsequent processing.

From the portion of the transport path of the paper 21 facing the index print section 44, the paper winding sections 19, 20
The portion up to this point is referred to as an index paper transport section 43. The index paper transport section 43 is provided with a pair of feed rollers 35 and 36, a pair of feed rollers 37, and a paper sorting section 38.

With the above-described paper drive unit and feed roller, the paper 21 is converted into a paper splicer unit 39, a paper cutter unit 40, an XY variable mask unit 41, a back print unit 42, and an index print paper transport unit.
After passing through 43, the paper is selectively sent to the first paper winding unit 19 or the second paper winding unit 20 by the paper sorting unit 38.

At the upstream side in the feed direction of the paper splicer section 39, the speed difference between the paper intermittent feed for printing exposure and the paper withdrawal feed from the paper supply section 18 is absorbed, and the paper 21 is joined. A first reservoir (paper storage section) R1 for forming a first loop 45 for increasing the processing time for cutting or cutting is provided. Also, between the main print position and the back print section 42,

The perforating means 43 provided in the main print unit 13 has a length obtained by adding the length of one photographic print and the length of a slight margin to the paper 21 along the longitudinal direction. Each time, a hole punch is punched, and there are three types of patterns different from each other. That is, as shown in FIG. 2, a cut punch (mark) C (formed on the lower end side of the paper 21) indicating an area for printing a general print (however, after the appearance of a sort mark, an area for printing an index print), an index A sort punch (mark) S (formed on the upper end side of the paper 21) indicating an area to print a print, a cut / sort punch CS indicating a break of a film (a break of a connected film, that is, a subject) (Formation).

The instruction of the type of the hole punch is made based on image data obtained by reading the film in advance by another digital reading apparatus described above. Further, the memory 62 associates the type of the hole punch punched for each exposure, the incidental information for each photographed frame read by the other digital reading device, and the exposure conditions for the paper 21 in the main print unit 13 in association with each other. To memorize. The detailed algorithm will be described later.

The back print section 42 and the index print section 44 each have a detecting means 61 for detecting hole punches punched in this way, and detect the type of hole punch. The types of the hole punches in the order (that is, the order formed in the main printing unit 13) are input, and the match or mismatch is determined by the control unit 64. If the holes do not match, the hole selected by the control unit 64 is selected. Subsequent processing is developed based on the type of punch. The detecting means 61 mainly includes a light emitter and a light receiver.

Next, the operation of the photographic printing apparatus 100 according to this embodiment will be described.

The paper 21 is pulled out from the roll paper 25 set in the paper supply unit 18, and a pair of feed rollers 27 provided in the first paper drive unit D1 and a pair of feed rollers provided in the second paper drive unit D2. FIG. 3 shows the algorithm of the operation in the main printing unit 13 which is sent by the printers 29 and 30 and set at the printing position.

First, the film carrier 19 of the negative transport section 11
For the negative 17 set in the main printing unit 13, that is, for the negative 17 to be exposed by the main printing unit 13 from now on, the control unit 64 sets the main printing unit based on the image data previously read by the other digital reading device described above. Department
It is determined whether the photographing frame set in 13 is to be printed in general (# 1). In the present embodiment,
A single print (general print) is sequentially performed for all the shot frames, and control is performed such that an index print is performed as needed after the single print is completed.

If it is determined that general printing is to be performed, control is performed to feed the paper 21 by a length corresponding to the size of the general print (# 2). The light source unit 22 illuminates the print target frame set at 16, and the image recorded on that frame is formed on the paper 21 via the shutter 23 by the zoom lens 24 (# 3).

Next, it is determined whether or not the exposed frame is the last photographed frame of the negative 17 ("Is it the end of one image?") (# 4). Here, since it is still the first sheet (P1 in FIG. 2), it is determined to be “N (No)”. Then, a cut punch C indicating a general print is formed by the punching means 63 immediately after the exposed print P1 on the lower end side of the paper 21 (# 5).

Next, the type of the hole punch for the print P1, that is, the cut punch C, and the supplementary information about the photographed frame corresponding to the print are associated with each other and sequentially stored in the memory 62 (# 6). The supplementary information is shown as "general print information" in the figure, but as described above, information on shooting conditions such as shutter speed, exposure opening value, use of strobe, comments at the time of shooting, and a number for identifying a customer Information mainly recorded in the magnetic recording band (recording layer) for each photographing frame of the APS film, such as information uniquely identifying an image such as a film serial number and a frame number, and other printing conditions in the main printing unit 31 Is included.

When the storage in the memory 62 is completed, the printing operation for one photo print is completed (# 7).

Similarly, the printing operation of the second, third,... Is sequentially performed, and the printing of the last sheet is completed (#
3) Then, when the index print is not used (#
At “N” at 1), the printing operation for one film is completed (“Y” at # 4), and this general print (P2 in the figure) is completed.
Immediately after 5), a cut / sort punch CS is formed (# 8). Note that the negative supply unit 14 sends the negative 17 photograph frames to the negative winding unit 15 one by one in synchronization with the feeding of the paper 21.

As described above, the cut / sort punch CS and the supplementary information are stored in the memory 62 in association with each other as a print corresponding to the print (# 9).

If the index print is to be printed after the general print ("N" in # 1), the length of the paper 21 corresponding to the size of the index print is changed.
Is transmitted (# 10). After the transmission, the index print (I) is performed without any printing action.
Whether P1) is the last print or not ("Is one piece finished?")
Is determined (# 11). Here, since it is necessary to print another index print (IP2), "N (No)" is determined. Then, a sort punch S indicating the index print is formed on the lower end side of the paper 21 and immediately after the unprinted area by the length of the index print IP1 (# 12). Then, as described above, the sort punch S and the accompanying information are stored in the memory 62 in association with each other as the one corresponding to the index print (# 13). Note that, as the supplementary information corresponding to the index print, information useful for the index print is cited among the supplementary information of the individual general prints constituting the index print.

Second index print (IP2)
Is the last print, "Is it one print? (# 11), the cut / sort punch CS is formed at the lower end of the paper 21 and immediately after the unprinted area by the length of the index print IP2 (# 14). ). As described above, the cut / sort punch CS and the supplementary information are stored in the memory 62 in association with the index print in the memory 62 (# 15), and the processing of one film in the main print unit 13 is performed. finish.

As described above, since the printing operation and the feeding operation are alternately performed in the main printing unit 13, the paper 21
Is intermittent.

The paper 21 sent from the main print unit 13 to the back print unit 42 through the second reservoir R2 is processed by the algorithm of the back print unit 42 shown in FIG.

First, the paper 21 is sent from the second reservoir R2 to the back print unit 42 (# 31), and a hole punch (C, S or CS) is detected by the detecting means 61 (# 32). On the other hand, the contents of the memory 62 are
That is, they are read out in the order in which they were formed by the main print unit 13 (# 33). The type of hole punch detected and the type of hole punch read from the memory 62 are collated by the control means 64 (# 34). If the collation result (# 35) matches (“Y” in # 35), the control means 64 determines that there is no hole punch detection error. If not (“N” in # 35), It is determined that a hole punch detection error has occurred.

If it is determined that there is no hole punch detection error, the control means 64 further determines whether or not the print type is a general print according to the contents stored in the memory 62 (#). 36). In the present embodiment, the print type cannot be determined from only the type of hole punch detected by the detection unit 61, and therefore the determination is made from the contents of this memory. In other words, if the hole punch is CS, it cannot be used alone to determine whether it is a general print or an index print, and even if the history of all prints included in one section of the negative is considered, all other cut punches are cut. If there is, it cannot be determined.

Next, if it is determined that the print is "general print", the step 33 is printed on the back of the printing area of the paper 21.
In (# 33), the additional information portion of the content read from the memory 62 is printed by the print head (# 3).
7) On the other hand, if it is determined that the print is an index print, step 3
3 (# 33), the additional information portion of the contents read from the memory 62 is printed by the print head (# 3).
9), the processing in the back print unit 42 ends (#
38).

In the algorithm of the back print unit 42, the process of feeding paper is adopted in step 31 (# 31). However, since the paper is always fed at a constant speed, it can be excluded from this algorithm.

If it is determined in step 35 (# 35) that there is a hole punch detection error, it is determined whether the data has been read from the memory according to the algorithm preset by the control means 64. Alternatively, a synchronization process (# 40) for matching one of the detected ones with the other is performed.

Here, the synchronization processing in step 40 (# 40) will be described. The table shown in FIG. 5A shows the types of hole punches (C, S, C) read from the memory 62.
S) and a process corresponding to a combination of the type of hole punch (C, S, CS) detected by the detection means 61, and a specific application case of each process is indicated by a corresponding circle numeral in FIG. ). In addition, in the table of FIG.
This synchronization processing is not applied to S marks and CS marks. In this case, step 35 (# 35)
This is because "matches".

The contents of this processing will be described. The priority order of these hole punch types is set in advance in the order of CS mark, S mark, and C mark, and the type of hole punch read from the memory 62 and the actual If the type of hole punch detected does not match the type of hole punch detected, the control unit 64 performs a process of selecting the type of hole punch having a higher priority among these two hole punches. Specifically, if the actually detected hole punch has a higher priority than the hole punch read from the memory (case,,), the memory punch is read from the memory until a hole punch that matches the detected hole punch is read. If the read data is skipped and the subsequent processing is performed, while the hole punch read from the memory has a higher priority than the detected hole punch (case,),
After the detected hole punch is invalidated, the subsequent processing is performed based on the hole punch read from the memory.

From the back print section 42 to the third reservoir R
The paper 21 sent to the index print unit 44 through 3 is processed by the algorithm of the index print unit 44 shown in FIG.

First, the paper 21 is sent from the third reservoir R3 to the index print section 44 (# 21), and the hole punch (C, S or CS) is detected by the detecting means 61 (# 22). On the other hand, the contents of the memory 62 are read out by the control means 64 in the order of storage (# 23). Then, the type of the detected hole punch and the type of the hole punch read from the memory 62 are collated by the control means 64 (# 24). If the collation results (# 25) match ("Y" in # 25), it is determined that there is no hole punch detection error. If they do not match ("N" in # 25), a hole punch detection error has occurred. Is determined to have occurred. The synchronization processing (# 29) by the control means 64 when it is determined that there is a hole punch detection error is the same processing as the synchronization processing (# 40) shown in FIG. 5 described above.

If it is determined that there is no hole punch detection error, it is further determined whether the print type is an index print according to the contents stored in the memory 62 (# 26). It should be noted that the type of print is not determined from the type of hole punch detected by the detection means 61 but is determined from the contents of the memory, as in the determination process (# 36) in the back print unit 42 described above.

Next, when it is determined to be "index print", the area of the paper 21 corresponding to the hole punch is an unprinted area which has not been printed by the main print unit 13, and The index print is printed (# 27) by irradiating the digital signal read from the hard disk for the index print with the light emitted from the LCD of the index print unit 44 (# 27), and the process ends (# 28).

If it is determined that it is not "index print", the process is terminated (# 28).

The speed difference of the paper 21 at each instant between the intermittent-feed main print section 13 and the continuous-feed back print section 42 is absorbed by the second loop 46 of the second reservoir R2. The speed difference of the paper 21 between the printing unit 42 and the index printing unit 44 of the intermittent feed at each moment is absorbed by the third loop 47 of the third reservoir R3. This allows the back print unit 42
In this case, the feed speed of the paper 21 can always be kept constant, so that high-quality printing can be performed, and the printing amount can be increased.

The photographic printing apparatus according to the present embodiment
Although the main print section, the back print section, and the index print section are arranged in this order with respect to the paper feeding direction, the photoprinting apparatus of the present invention is not limited to this configuration. For example, the configuration may be such that the order of the back print unit and the index print unit is reversed.
