Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a pressure printing device, and more particularly to a pressure printing device equipped with a print positioning device.

BACKGROUND OF THE INVENTION A press-type printing device includes a base having a pressure-receiving surface, a pressing position in which the pressing surface is pressed against the pressure-receiving surface, and an open position in which the pressing surface is separated from the pressure-receiving surface. A pressing type printing device including a pressing plate movable with respect to the base in between, and configured such that a printing original plate is attached to the pressing plate is disclosed in Utility Application No. 50-94408 filed by the same applicant as the present applicant.

No. 51-114253 (Jikko No. 57-15814), patent application No. 59-
It has already been proposed in the issue.

In the above-mentioned type of press-type printing device, the printing original plate attached to the pressing surface portion of the pressing plate is placed on the pressure-receiving surface portion of the base by the pressing plate. Printing is performed by pressing the paper against the paper.

In printing with the above-mentioned pressure-type printing device, the printing position is determined by the placement position of the printing paper on the pressure-receiving surface of the base, and therefore, the printing paper is placed at the correct position on the pressure-receiving surface. If not,
The print position on the print paper fluctuates. Particularly in the case of business cards, which have a relatively small printing position and are strictly required to be printed in the correct position, the work of placing and positioning the printing paper on the pressure-receiving surface becomes troublesome. Therefore, especially in such printing, it is required that the printing apparatus be provided with a print positioning device for positioning the placement position of the printing paper.

The above-mentioned printing positioning device is required to be able to adjust not only the translational movement of the printing paper placement position along the pressure-receiving surface, but also the tilting movement adjustment around the axis perpendicular to the pressure-receiving surface. A print positioning device having such an adjustment function has a complicated structure and is large-scale, and is often unsuitable for small-sized press-type printing devices.

OBJECTS OF THE INVENTION An object of the present invention is to provide a press-type printing device that is equipped with a parallel movement adjustment function and a tilt movement adjustment function, and is equipped with a printing positioning device that is simple in structure, compact, and easy to handle. .

Structure of the Invention According to the present invention, in the press type printing device of the type described above, the base has a pair of guide end surfaces extending parallel to each other on both sides of the pressure receiving surface. The base is provided with a stopper-type printing positioning element extending across the pressure receiving surface and press-engaging with the guide end surface at both ends, and the printing positioning element is provided at both ends. The base is slidable relative to the base in the direction in which the guide surface extends in substantially point contact with the guide end surface at the guide end, and is tiltable relative to the base with the end as a pivot point. This is achieved by a press type printing device which is configured to be fixed to the base at any sliding or moving position due to frictional resistance with the base.

Effects of the Invention According to the above-described configuration, the parallel movement adjustment and the tilt movement adjustment of the printing paper placement position are performed by only one member called the print positioning element, and the base of the print positioning element Fixation to the stand is performed without requiring special fastening operations.
