Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a method of classifying a punch hole on a photographic paper formed in a photographic printing process as post-processing data and performing post-processing based on the data. Regarding improvement. (Prior Art) When printing a photo, the image of the negative film is sequentially sent on a long printing paper by image frames and printed, and the printing paper is sequentially developed, washed, dried, cut, It is completed as a print by post-processing such as sorting, but post-processing in this process, especially cutting, post-processing differs depending on each order,
In addition, it is required to be processed separately for each orderer. Conventionally, as this classification processing method, when sorting is performed according to the orderer, (1) punch holes drilled opposite to both side edges along the length direction of each printed image on photographic paper, or (2) ) The data is detected based on the presence or absence of two punch holes perforated in the direction perpendicular to the length direction of the photographic paper on one side edge of the photographic paper, and the punches within two locations using only one side edge. In some cases, holes are formed, the data is detected based on the presence or absence of the punch holes, and the distance from the reference position, and these data are used for post-printing processing. In the former method (1), a device for punching a punch hole must be installed on both side edges of the photographic paper, and similarly, a sensor for detecting the punch hole must be installed oppositely. In addition, the method (2) requires a device for punching parallel punch holes, and the arrangement and number of sensors to be detected must be devised. The latter method is limited to two punch holes. Since the data is formed only by the relative relationship, the post-processing ability is small and the efficiency is low. (Problems to be Solved by the Invention) The present invention efficiently forms data from punch holes in the printing process, thereby increasing the sorting capability for post-processing, and thus, punching only one side edge of photographic paper. An object of the present invention is to enable countless data to be formed by using punch holes. (Means for Solving the Problems) In order to achieve the above object, the present invention detects punch holes formed for each printed image on a long photographic paper in the course of a photographic printing process, and stores the data in a printing process. In the method used in the processing, on one side edge along the transport direction of the photographic paper, three or more punch holes are arranged and collected along a transport direction on a single line by changing the number or the distance between the holes. Alternatively, the present invention relates to a classification method in a photographic printing process, in which the respective data are classified and arranged and used for post-processing by punching and forming them in combination. (Operation) By punch holes drilled on the side edge of the photographic paper in a row of three or more for each printed image frame, the punch holes are not limited to one-to-one limited relative punch holes, but are sequentially related back and forth. Also, depending on the distance between holes or the number and distance between holes, various combinations can be developed and countless data can be formed, so that punch holes are formed only on one side edge of the photographic paper. It is possible to classify the prints innumerably and perform the post-processing simply by piercing them. A punch hole punching device and a detecting device are provided on a single line corresponding to one narrow side edge along the transport direction of the printing paper, so that the punch hole punching device and the detecting device can be simplified and sufficiently used. The arrangement of punch holes can be perforated and detected in the direction following the flow of the photographic paper in the transport direction. The number of three or more punch holes to be provided in series and the distance between the holes are different from each other, and numerous print information is clearly classified without duplication and confusion, and used for post-processing by countless data combined. Can be. (Example) Next, a specific example of the classification method according to the present invention will be described with reference to the drawings. FIG. 1 is an explanatory view showing print data by punch holes on photographic paper in a classification method embodying the present invention.
The figure is a similar explanatory diagram showing another embodiment. In the drawing, (1) a long photographic paper, three or more punch holes (2) and (2) on one side edge (1a) along the length direction of the photographic paper (1) during the printing process. To each image (3)
(3) The holes are drilled in parallel on the basis of the upstream part so as to proceed in the flow direction for each frame. For example, as shown in FIG. 1, three punch holes (2)
In the data based on (2), the data of each print (3) (3) is formed by changing the distance (A) (B) of each punch hole (2) (2). In the distance (A) between the first hole and the second hole, data without an edge and with an edge are formed. A small (about 1 mm) data of the distance (A) is data without a border, and a large (about 2 mm) data is an edge. There is existing data. The distance (B) between the second hole and the third hole is print number data, and print number data for each orderer is formed about every 1 mm. Also, as shown in FIG. 2, four punch holes (2) are provided.
In the data based on (2), the data is formed by the combination of the number and the position of the missing punch hole (2), and 16 types of data are formed as shown in the table below. Can be. In this way, by combining the methods based on the three and four punch holes (2) and (2) with each other from the above example, it is possible to form an infinite number of data. Is used as post-processing in the photo printing process, for example, as information for classifying by cutting or by each orderer. The punch hole (2) is formed by a punch hole punching device after printing images (3) and (3) for each frame on a long printing paper (1) during the photographic printing process.
(2) is detected by a sensor, and post-processing of each print is performed based on the information. For example, in the case of use for cutting photographic paper (1), an optical sensor provided in front of a cutting device is used for cutting marks. After detecting the punch holes (2) and (2), the cutting device operates and cuts when the distance (the distance to the cutting blade) determined by the drive motor that is transporting the printing paper (1) is fed. . When used for sorting prints by orderer, data from the punch holes (2) is detected, and prints are sorted and sorted for each orderer. The punch hole (2) is left at the white edge in the case of bordered printing, and the punched hole (2) is punched in the margin between images in the case of borderless printing, and twice the cutting blade. It is cut off by cutting. In all of these embodiments, the classification method according to the present invention has been described as an example in which the printing method is used for cutting prints in the course of photo printing processing and post-processing classified by orderer. This can also be used as print information for auto setup. (Effect of the Invention) According to the classification method of the present invention, as described above, three or more punch holes are printed on one side edge of the photographic printing paper in the conveying direction on one side edge of the photographic printing paper in a single line. The number of punch holes and their positions or distances between holes are changed, and these are combined with each other, so that the data formation can be developed to infinity. In order to classify a large number of different prints such as types printed on paper and orderers based on information obtained by detecting countless different punch holes (data) formed innumerably, and to operate a post-processing device,
The various congested prints can be sorted neatly by the punch holes (data) of abundant mass formed clearly without duplication, and post-processing can be performed accurately, quickly and efficiently. In addition, the clear and innumerable data formation by such a classification method makes it possible to classify various kinds of prints in order and to increase the data storage capacity until the data can be sufficiently digested. The formation of only the side edges becomes easier and more reliable, and the punch holes arranged on a single line can be detected quickly and easily by proceeding with the conveyance. The installation device and the detection device can also be simplified, which is advantageous in that various complicated data formation and detection on both side edges on the photographic paper can be avoided.
