Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention enables the observation and determination of an original image, such as a color negative film, for example, and inputting appropriate exposure conditions using the keyboard based on the correction value, and printing. Concerns the improvement of photographic printers that expose and print light-sensitive materials such as paper.

[Prior Art] When printing an original image such as a color negative film onto a photosensitive material such as photographic paper, the printing conditions are not the same depending on the original image (frame). Prior to printing, the amount of transmitted light (generally the amount of light separated into three colors) and color balance of the original image are automatically measured for each frame of color negative film, and the printing conditions are then set. The printing conditions obtained are not valid for all original images.

In other words, the original image on a color negative film varies depending on factors such as overexposure or underexposure, differences in light sources, subject environment, light distribution, etc. There are differences in negative density over this wide range.

On the other hand, images printed on printed photographic paper are required to have high image quality with good color tone and density. For this reason, the burn-in is performed by so-called manual determination, in which the operator makes corrections based on the burn-in condition determined by the above-mentioned automatic measurement. That is, an operator visually observes the original image every frame and corrects the measured value.

This correction is performed using a keyboard for setting printing conditions connected to the color printer. The keyboard is B,
It consists of a plurality of color step Y keys, M keys, and C keys for correcting G and R color lights, and a plurality of density step D keys for correcting overall light.

Conventional keyboards are either integrally fixed to the color printer body or placed on an operation table.

When performing printing using the above color printer, the operator faces the printer main body and attaches a roll or strip of negative color film to the printing optical system position, operates the control 1 display, etc., and prints the image. The original image of the negative film inside the front observation window is visually determined to be zero, and the Y key, M key, C key, D key, etc. on the keyboard are operated.

[Problems to be solved by the invention] There are two types of workers who perform the above operations: left-handed and right-handed.
It would be convenient if the keyboard could be moved freely to either the left, right, or center position so that it can be operated with both hands by any worker.

However, the conventional integrated keyboard fixed to the printer main body is difficult to use because some operators have to use both hands or one hand during the operation. - The detachable keyboard that is placed freely on the printer's operating table can be moved freely during the above operations, but because there are too many degrees of freedom, it is difficult to handle the keyboard each time to place it in a predetermined position. Otherwise, troubles may occur such as accidentally hitting the keyboard or dropping it on the floor and damaging it. Furthermore, when the separated type keyboard is placed on an operation table, it protrudes from the table and becomes high, making key operations difficult.

[Means for Solving the Problems] The present invention aims to improve the operability of the keyboard of a photo printer, and to provide a printer that is easy to use regardless of whether the left or right hand is using the work sound. be.

The above object is to provide a photographic printer for printing an image on a photographic film onto a photosensitive material, and to provide an operation console having at least the photographic film (1) and a keyboard section for inputting printing conditions for printing the image on the photosensitive material (2). This is achieved by a photographic printer, characterized in that the keyboard section is movably installed at an arbitrary location on the operation desk.
