Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an original of a trimming instruction device that performs the work of determining the composition of a necessary part of a photographic original when the composition is determined and printed. Relating to mobile devices.

[Conventional technology]

When a portion of a photographic original plate is stretched and printed, trimming is performed in which the excess portion around the portion is cut off and removed. For example, when trimming a desired portion 2 shown by a dotted chain line at the top of the figure from a photographic original plate 1 shown by a solid line in FIG. 13, a portion around the desired portion 2 is removed.

When performing such trimming, move the photographic original plate 1 so that the center ○ of the desired area 2 coincides with the center of the printing photosensitive material such as photographic paper (the center of the printer), and mark the periphery of the desired area 2. Then, the enlargement magnification is determined so that the peripheral portion has a size corresponding to the print size.

This trimming operation is performed in a conventional manner.

An operator sets a photographic original plate 1 in a printer, captures the photographic original plate 1 with a television camera equipped with a zoom lens, and displays the image on a display. Then, while visually checking the image displayed on the display, the operator rotates or moves the photographic original plate 1 to align the center O of the desired portion 2 with the center of the display, so that the desired portion 2 is The image is enlarged to the print size and the enlargement magnification is determined. It is then printed by the printer.

[Problem that the invention seeks to solve]

However, conventional trimming operations have the following problems.

The trimming work is performed by moving or rotating the photographic original plate 1 vertically and horizontally, and requires skill because this work is done by hand. For this reason, when printing while trimming, at least one skilled person must be present at the printer stand.

On the other hand, printing work is almost automatically performed by the printer, and is completed by operating the printer's start switch.

Therefore, the time required to obtain a print of the desired portion 2 from the photographic original 1 is almost determined by the trimming operation, and since this operation requires skill, trimming and printing take a considerable amount of time.

Furthermore, if you perform trimming and printing multiple times and remove the photographic original 1 set at -degree from the printer, you will have to move or rotate the photographic original 1 again. The trimming operation takes a considerable amount of time and is extremely troublesome. Such reprinting occurs when the currently obtained print is inappropriate or when there is a request for additional printing at a later date. Furthermore, when printing multiple times, it is difficult even for an expert in trimming to obtain the same print as the previous print.

Therefore, the trimming work and the printing work are performed using separate devices, and the trimming instruction device that performs the trimming is
By acquiring trimming data regarding the movement, rotation, and enlargement magnification of the photographic original and operating the printer based on the trimming data, efficient trimming and
Can perform printing work.

Therefore, this invention improves the efficiency of printing work by performing trimming work and printing work using separate devices, so that a person skilled in trimming work can operate multiple printers. Another object of the present invention is to provide an original plate moving device for a trimming instruction device that improves the operability of the trimming instruction device for performing trimming operations.

[Means for solving problems]

In order to achieve the above object, an original plate moving device according to the present invention provides a printer that extracts a part of an image recorded on a photographic original plate, enlarges it to a desired print size, and prints it. a first moving means for moving the photographic original in a first direction; and a second moving means for moving the photographic original in a second direction intersecting the first direction.
The original plate moving means includes a moving means and a rotating means for rotating the photographic original plate in a plane including the first direction and the second direction, and the photographic original plate is moved at a predetermined position of the original plate moving means. The present invention is characterized in that it is provided with an original plate holding means for holding the original plate.

[For production]

The photographic original plate requested to be trimmed is held by the original plate moving means by the original plate holding means. and,
The photographic original is moved by operating the first moving means and the second moving means so that the desired portion for which trimming is requested is at a predetermined position for trimming. At this time, what is the moving direction of the first moving means and the moving direction of the second moving means?

Since they intersect, the photographic original plate can be moved to a predetermined position by adjusting the amount of movement by the first moving means and the second moving means. Then, the photographic original plate is appropriately rotated by the rotating means to determine the printing direction of the desired portion.

The thus obtained movement amounts of the first and second moving means and the rotation amount of the rotation means may be recorded, and based on the records, the printer may be operated to print.

However, for example, the θ table 25 may be placed on top of the , and the X-direction table 24 may be disposed thereon. In this case, the moving directions of the first moving means and the second moving means can be in a relationship other than at right angles, and the original holding means is arranged on the X-direction table 24.

Furthermore, although an IC card is used as the recording medium of the external storage device, a magnetic disk, an LSI card, or the like may also be used.

Furthermore, in this embodiment, the method for determining the trimming data of the movement of the photographic original plate 1 and the enlargement magnification has been described, but at the same time as determining the trimming data, color correction and exposure are performed while visually checking the image displayed on the display device 30. It is also possible to determine print data for over-exposure, under-exposure correction, etc., and to store these print data together with the trimming data in an external storage device. In this case, when the image is sent to a printer, there is no need to perform color correction or the like, making the printing process easier.

〔Effect of the invention〕

As explained above, the original moving device of the trimming instruction device according to the present invention includes an original moving means for appropriately moving the photographic original in the vertical and horizontal directions and rotating the photographic original as appropriate. can be easily adopted. Moreover, since the photographic original plate can be moved regularly, trimming data can be easily obtained.

Further, since the trimming instruction device is separated from the printer and only determines trimming data, only the operator who operates this instruction device needs to be skilled. Moreover, since the trimming data can be stored in an external storage device and read out by the printer and automatically trimmed and printed, anyone can operate the printer. Therefore, trimming data can be determined using one trimming instruction device and printing can be performed using a plurality of printers, so that trimming and printing operations can be performed efficiently and a large amount of photographic originals can be processed in a short time.

Furthermore, since the printer can be operated at full capacity, running costs can be reduced.

In addition, by using this trimming instruction device to determine print data related to color correction, correction of overexposure, underexposure, etc. together with the determination of trimming data, more efficient trimming and printing work can be performed.
