Abstract

PROBLEM TO BE SOLVED: To provide a printing stamper inspection machine with improved working efficiency and less occupation space of a floor surface. SOLUTION: An oblique and solid frame 2 is buried on a substrate 1, a movable plate 4 which is slid and displaced in upper and lower directions on the front surface of the frame 2 is provided, guide rails 5A and 5B for crossing the front surface of the movable plate 4 in left and right directions are provided, a small magnifier guide 5 whose both edges are supported by the frame 2 and which is slid and displaced in upper and lower directions is provided, and a small magnifier 6 which is slid and displaced left and right along the small magnifier guide 5 is provided. A printing stamper to be inspected is applied to the movable plate 4, for example, by a magnet.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a printing original plate inspection machine for visually inspecting stains and the like on a printing original plate such as offset printing.

[0002]

2. Description of the Related Art A printing original plate is usually 1200 mm × 900
It is about the size of a whole sheet of paper, but in the past it was spread on a horizontal table and held with a magnifying glass in hand for inspection.
Depending on the inspection location, it is necessary to perform the inspection in a bad posture, such as leaning out of the body on the table, and the horizontal table requires a large space.

[0003]

Therefore, according to the present invention, it is possible to continue the work in a standing posture or a comfortable posture in which the user sits down on a work chair, and the diagonal rigid shape occupies a small space on the floor surface. We provide a printing plate inspection machine (which can also be used as a correction workbench) that can work in a small space along the wall surface, constantly inspects the area to be inspected, and has a magnifying glass attached to it to reduce eye strain. .

[0004]

Means for Solving the Problems A printing plate inspection machine of the present invention is a diagonal rigid type frame that can move on the floor and has a size of about the size of all sheets, and is slidably displaced in the vertical direction on the frame. A loupe having a movable plate on which a printing original plate to be inspected is attached, and guide rails that cross the front surface of the movable plate in the left-right direction, and both ends of which are supported on the left and right sides of the frame and are slidably displaced in the vertical direction It is characterized by having a guide and an enlarged loupe that is slidably displaced in the left-right direction along the loupe guide.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a front view of an embodiment of the present invention, and FIG. 2 shows a side view. The base 1 is, for example, 1200 m
It is a rectangle of about mx 600 mm, and is located at the four corners of the floor.
Casters or legs are provided and can be installed on the floor. An oblique rigid frame 2 is planted on the base 1. The frame 2 is inclined toward the rear toward the upper side, for example, at an angle of 75 ° with respect to the horizontal, and double guide rails 3A and 3B are provided on both left and right sides.

The movable plate 4 on which the printing original plate to be inspected is attached is, for example, 1300 mm wide and 900 m vertically.
It is a square plate of m and is embedded with a very thin iron plate for attracting magnets on the entire surface, and it can be manually displaced in the vertical direction along the guide rails 3A and 3B, Since it is connected to the provided balance weight, it can be stably stopped at a position displaced arbitrarily. A printing original plate to be inspected can be attached to the surface of the movable plate 4 and fixed by using a magnet. In the loupe guide 5, two guide rails 5A and 5B traverse the front surface of the movable plate 4 in the left-right direction, and both ends of the loupe guide 5 are engaged with the guide rails 3A and 3B, so that the entire loupe guide can be manually displaced in the vertical direction. it can. The loupe 6 can be manually displaced to an arbitrary position in the left-right direction along the guide rails 5A and 5B and stopped. A lamp 7 for illuminating the printing original plate is built in the guide rail 5A on the upper side of the loupe guide.

When using this inspection machine, a printing original plate to be inspected is attached onto the movable plate 4, and the loupe is moved by operating the vertical displacement of the movable plate 4, the vertical displacement of the loupe guide 5, and the horizontal displacement of the loupe 6. If 6 is aligned with the position to be inspected on the original plate, that part can be magnified and viewed,
By sequentially moving the inspection position, the entire printing original plate can be inspected. Then, when a spot, a missing page, a typographical error, etc. are found, the correction can be made on the spot.

As a modified embodiment of the present invention, a correction liquid ejecting device may be additionally provided in the vicinity of the loupe, and a loupe having a different focal length may be selected and replaced, or two kinds of loupes may be rotated to be selected. It may be configured to be able to do so. Also, the base 1
The tilt angle of the frame 2 with respect to may be adjustable.

[0009]

EFFECTS OF THE INVENTION According to the present invention, it is possible to continue the work in a comfortable posture without leaning or bending over, while standing or sitting on a chair, and use the loupe by hand. Since you can always see a magnified image in front of you without holding it, eye fatigue is reduced and work efficiency is improved. Moreover, since the whole is solid, the floor area is small.
