SOLUTION: A short side 24 of a holding part 23 is arranged at a specific position so that a surface of a polyhedron 11 held on a side surface 22A being horizontal of a rotary part 21, and a side surface 11B of the polyhedron 11 held on a holding part 23 of a side surface 22B facing a supply means 13 are flush with each other. Printing treatment is simultaneously applied to the surface of the polyhedron 11 and the side surface of the next polyhedron 11. Since the polyhedron is continuously supplied to a rotary holding means thereby, and different surfaces of two pieces of polyhedrons on the rotary holding means are simultaneously treated by a treating means, treating efficiency is improved. Further, since two surfaces are treated at once by one time holding, and for example, designs for two surfaces can be formed on the same plate, mutual positional precision of the treatments can be improved.

2. Description of the Related Art Conventionally, a case or the like having a certain shape is generally subjected to printing or other various surface treatments in order to enhance the display and design required for the product. In addition, in this case and the like, there is a functional one that can perform a certain operation, not just a box-shaped one for storing. A typical example thereof is a cassette case in a video tape cassette.

Some polyhedrons such as the cassette case have various printings on two different surfaces. When these printings are performed by, for example, screen printing after the polyhedron is formed, conventionally, the printing is performed on each surface separately at different stations, or at one station, after printing on one surface of the polyhedron, the same station. It was normal to print on another side. Also, especially when printing on the lid of a relatively small part that can be opened and closed on the front side of the cassette case, it is difficult to hold and fix the lid, and scratches may occur due to the parts rubbing against each other when handling the parts after printing. There was a high risk of such problems.

This can be achieved by a carrying method characterized in that the polyhedron held in two postures is sequentially discharged from the holding / fixing position.

In this carrying method, the different surfaces of the two polyhedrons can be processed simultaneously, so that the working efficiency is improved. The above-mentioned object of the present invention is to hold two different polyhedrons with their different surfaces arranged side by side on the same plane, and to hold the polyhedron by a rotation holding means, a supply means for supplying the polyhedron to the rotation holding means, and the rotation. Processing means for simultaneously performing a predetermined process on the two surfaces of the polyhedron held by the holding means, and processing of two surfaces of the polyhedron on the rotation holding means subjected to the predetermined processing by the processing means And a discharging device for sequentially discharging the discharged products.

In this carrying device, the polyhedron is continuously supplied to the rotation holding means, and different surfaces of the two polyhedrons on the rotation holding means are simultaneously processed by the processing means, so that the processing efficiency is improved. Further, since the two surfaces are processed by holding once, the mutual accuracy of the processing is improved. The above-mentioned object of the present invention is to sequentially supply the polyhedra one by one and to supply the polyhedra one by one when performing the printing process on two different faces of the polyhedra that are sequentially supplied.
The different faces of the polyhedrons are arranged side by side on the same face, and the two faces of the arranged polyhedrons are simultaneously subjected to a predetermined printing process, and then the polyhedrons subjected to the printing process of the two faces are sequentially discharged. Further, it can be achieved by a printing method characterized in that the rearrangement of the polyhedron is performed together with the supply.

In this printing method, printing is simultaneously performed on two different surfaces of the two polyhedrons, so that the printing efficiency is improved. The above-mentioned object of the present invention is to hold the two different polyhedrons supplied by the supply means in different planes side by side on the same plane, and to rotate the polyhedron.
Printing means for simultaneously performing printing processing on the two surfaces of the polyhedron held by the rotation holding means, and printing of two surfaces of the polyhedron on the rotation holding means subjected to printing processing by the printing means.

In this printing apparatus, the polyhedron is continuously supplied to the rotation holding means and different surfaces of the two polyhedrons on the rotation holding means are simultaneously printed by the printing means, so that the printing efficiency is improved. Further, since printing is performed on two sides by holding once, mutual accuracy of printed contents is improved. Further, in the printing apparatus, by configuring the polyhedral holding portion of the rotation holding means to be adjustable according to the size of the polyhedron,
By adjusting the polyhedron holding portion, polyhedra of various sizes can be held and printing can be performed on the two surfaces of this polyhedron at the same time. Therefore, a two-sided design can be formed on one plate, and cost reduction and accuracy improvement can be achieved.
