Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a printer called an automatic printer or the like, and is particularly characterized in that it is improved so that its width can be shortened.

Currently, printers, which are called automatic printing machines, are equipped with a roll of long photosensitive paper, that is, a long photographic paper, mounted on one side of a horizontally long dark box, and then transferred to the other winding section, etc. Because the dark box is fed out intermittently, and when it stops, the printing is done in the center of the dark box, there is a certain limit to how much the width can be shortened, and this is due to the floor space required for installation. There was a problem. This tendency becomes especially noticeable when processing equipment and printers are installed in a series, from developing photographic materials to exposing and printing onto photographic paper, and from developing to drying the photographic paper. Downsizing of equipment and printers was considered an urgent need in this industry.

In view of the above-mentioned current situation, the present invention makes the feeding direction of the photographic paper that is intermittently fed out for printing exposure in the dark box of the printer to be vertical, similar to the optical path for printing exposure, and By directing the light path toward the photographic paper using a mirror placed in the middle, not only does this eliminate the need for a long width as in conventional printers of this type, but it also eliminates the need for the long width of conventional printers of this type. By retracting the printer out of the optical path for printing exposure, it is possible to provide a printer that can perform trimming operations extremely easily. This will be explained below.

First, the external configuration of the printer according to the present invention will be explained with reference to an external perspective view in FIG. 1 and a partially enlarged external oblique view in FIG. The upper plate part 1 includes a negative mask stand part 2 equipped with stoppers 207, 207' for the negative mask 15, and a hood for determining the density and color area of the negative film (not shown). A window section 3, a trimming window section 4 whose hood and the like are not shown, a control panel 5 equipped with printer operation control dials, a keyboard 6 equipped with a large number of keys for operating the printer, and a negative mask etc. In addition to forming an accessory case 7 for storing small items, a light source box with a mirror tunnel part 104 suspended above the negative mask stand part 2 is provided on the support 8 established on the upper plate part 1. 10 is supported. 11 is a trimming dark box of which the upper plate part 1 is a component; 12 is a dark box for exposing and printing photographic paper connected to the rear of the trimming dark box 11; 13 is behind the upper plate part 1; This is a dark box for loading long photographic paper which is connected above the dark box 12 for exposure and printing. Reference numeral 14 denotes a control box that is connected to the left side of the trimming dark box 11 below the upper plate part 1, and a part of the control box is a switch panel 1 to which the printer's main switch etc. are attached.
41, and a main electric circuit used for starting, operating, and stopping the printer is built inside.

In particular, the upper plate part 1 and the outer plates for forming the trimming dark box 11, the exposure and printing dark box 12, the photographic paper loading dark box 13, etc. are arranged in a series so as to be able to block light. As will be described later, the space between the dark box 11 and the dark box 12 for exposure and printing can be shielded from light during trimming.

It will be done. In this way, the sheet-like photographic paper P, which has been made into one photo, is passed through the photographic paper suction fan 1205.
It is suctioned and held at an accurate printing exposure position on the vertical guide plate 1202.

Exposure printing is performed in the above state, and after the printing exposure, the reversible motor 1237 is reversely rotated, the reciprocating rotary disk 1233 is rotated counterclockwise in FIG. 11, the opening/closing guide plates 1206 and 1207 are closed, and the The state shown in FIG. 12 is restored.

Therefore, while the photographic paper suction fan 1205 is stopped, each driving roller 1218 is driven, and with the cooperation of each driven roller 1221, 1222, the photographic paper is sent to a high-speed conveying device section 1250, and then passed through a low-speed conveying device section 1260 (not shown). It sends it to the processor.

After that, the above operation will be repeated.

Further, the cutter 1306 in the dark box 13 for loading long photographic paper is installed at the feeding section of the processor, etc.
The vertical guide plate 1202 for supporting photographic paper in the exposure device section 1201 inside the dark box 12 is accurately moved from inside the dark box 13 by a length corresponding to one photograph. It is also possible to feed out the long photographic paper P in a continuous manner from the printing exposure position to the point where the photographic paper is cut.
Further, it is a design problem that a person skilled in the art can easily solve, such as allowing the photographic paper suction fan 1205 to rotate continuously without stopping.

As is clear from the above description, the printer according to the present invention has a trimming dark box disposed below the light source box, an exposure and baking dark box behind the trimming dark box, and a trimming dark box behind the trimming dark box.
