JPS5852207B2 - A plate-making camera that can also be used as a contact printer - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a plate-making camera machine that can also be used as a contact printer for reversing the negative or positive of photographed film, and more specifically, the film clamping mechanism of the contact printer can be attached to the photographing section of the plate-making camera machine for printing film for the printer. Installed as a mounting board,
This invention also relates to a plate-making camera machine that can be used as a contact printer by making a condenser lens for a printer compatible with a plate-making lens.

To create a printing plate using photoengraving, it is first necessary to prepare a variety of equipment, including a plate-making camera to photograph the manuscript, a contact printer to reverse the film negative and positive, and a printing frame to print the film onto the printing plate. There were problems in terms of cost and securing installation space.

The present application was developed in view of the above-mentioned circumstances, and aims to make a plate-making camera machine also function as a contact printer (by devising a structure, it aims to save labor in terms of equipment for photolithography).

The plate-making camera machine according to the present application will be described in detail below. Its configuration includes a cover plate 1A on which a sponge 1a or a similar material is laid, and a transparent glass plate 1B in which a film can be inserted freely between the surface of the sponge 1a. A film mounting board 1 for a printer is constructed, and the board 1 is hinged to a frame 2 surrounding it, and the frame 2 is hinged to face the film suction cup 11 of the photographing unit main body 10. A further feature is that the light source 3 with a condenser lens for a printer is interchangeable with the lens 13 for plate making.

The drawing shows an embodiment of the present invention in a floor-type plate-making camera machine, in which the mounting plate 1 is hinged to the lower side of the frame 2, and the frame 2 is hinged to the photographing unit main body 10 of the camera machine at its side. (See Figures 1 and 2).

Therefore, when using the plate making camera of the present invention as a contact printer, rotate the film suction cup 11 of the photographing section outward to remove it from the optical axis, flip up the focusing glass 12, and then move the mounting plate 1 into the frame. Rotate it by 2 and place it on the optical axis.

At this time, the window hole 10A of the photographing section main body 10 is closed.

Then, tilt the mounting plate 1 90 degrees toward you so that it is in a horizontal state.
Next, the glass plate 1B is flipped up and a negative or positive film 4, which is inverted, is overlapped with the printing film 5 and inserted between the glass plate 1B and the sponge surface 1a of the lid plate 1A and pressed together.

Further, at this time, the lens portion is in a fixed state, and the power supply 3 with a printing capacitor is compatible with the plate-making lens 13.

For example, a compatible method is to attach them to the same board and slide them (see Fig. 3).

The embodiment shown in FIGS. 4 and 5 shows a floor-type plate-making camera machine that combines the present invention with another invention in which the original plate 21 also serves as a printing frame.

The structure of the plate-making camera that also serves as a printing frame consists of a vacuum plate 21A on which a sponge 21a or a similar material is laid, and a transparent glass plate 21B into which manuscripts, printing plates, etc. can be inserted freely between the sponge 21a and the vacuum plate 21A. In addition to configuring the original placing plate 21, the iron plate 21 is pivotally supported on a frame 22 that slides on the bed 14, and a printing light source 23 is provided on the frame 22 separately from the photographing light source 15. It is characterized by

The printing light source 23 can be adjusted by vertically sliding a lamp 23B on a support 23A erected on a frame 23, as shown in FIG.

Additionally, 22A is a clamp for holding the original platen 21 in a horizontal state when used as a frame.

In this embodiment, in order to insert an original, a printing plate, etc. onto the original placing plate 21, one side of the glass plate 21B is hinged to the vacuum plate 21A so that the glass plate 21B can be rotated. and sponge 21 of vacuum plate 21A
Insert the manuscript, etc. between side A and side A.

At this time, in order to sandwich the negative 24 and the printing plate 25 as a printing frame, an appropriate vacuum device is further installed on the vacuum plate 21A.
Connect to and apply suction crimping.

FIG. 5 shows the state when used as a baking frame.

The configuration and embodiments of the plate-making camera according to the present application have been described in detail, and the configuration produces the following effects unique to the present invention.

The camera body 10 is provided with a film mounting board 1 for a printer in addition to a film suction cup 11 for photographing, and the light source 3 with a condenser lens for printers is made interchangeable with the plate-making lens 13. In addition to its functions, it also has the function of a contact printer for reversing negatives or positives, so it is highly functional.

Therefore, the present invention is extremely economical in terms of equipment costs and required space, compared to the previous case in which photographing and printing were performed using separate devices.
