ことが出来ない欠点があった。(b) Problems to be Solved by the Prior Art and the Present Invention Currently, in a screen printing machine, a printing table equipped with suction means for a printing material is attached to the upper surface of a suction case linked to a vacuum device. The vacuum device is operated to suck the air inside the suction case, thereby suctioning the printed materials stacked on the top surface of the suction case. In order to achieve good performance, the suction holes that are not blocked by the printing material must be sealed in advance using adhesive tape, etc., which requires time and effort to prepare before starting the printing machine, and also prevents the use of adhesive tape, etc. It has the disadvantage that printing work cannot be done efficiently because it is expendable.

を行うことが出来るものである。(c) Means for Solving the Problems In view of the problems of the conventional printing table as described above, the present invention provides a large number of suction holes for sucking the printing material on the top surface of the suction case linked to the vacuum device. A large number of valve chambers are provided in the lower part of the suction hole in communication with the suction hole, each valve chamber is supported by a spring and contains a ball valve, and the lower part of the valve chamber is opened in the suction case. When the vacuum device is operated and printing materials of any size are piled up on the top surface of the suction case, the suction force of the vacuum device is applied to the opening of the valve chamber corresponding to the suction hole that is not blocked by the printing materials. The ball valve that descends automatically seals and isolates it from the atmosphere, and the valve chamber corresponding to the suction hole that is blocked by the printing material is lowered to below atmospheric pressure by the suction force of the vacuum device, and the three valves are placed in the valve chamber. Because it is in a floating state, the suction hole that is not blocked by the printing material as in the past does not need to be blocked with adhesive tape, etc., without reducing the suction power of the vacuum device.
The printing material can be adsorbed onto the upper surface of the suction case and printing can be performed efficiently.

発揮するものである。(E) Effects of the Invention The present invention provides that when the vacuum device is operated as described above and printing materials are piled up on the top surface of the suction case, some of the many suction holes provided on the top surface of the suction case are blocked by the printing materials. The three valves in the valve chamber corresponding to the suction holes that are not covered are automatically brought into close contact with the lowered openings to block the inflow of air into the suction case. For the three valves, the opening of the valve chamber is not sealed by the suction force of the vacuum device, so there is no need to use adhesive tape or the like to cover the suction hole in the area that is not covered by the printing material as in the conventional method. Even if the printing material is strongly attracted to the top surface of the suction case without reducing the suction power of the vacuum device, it is possible to improve the efficiency of middle column work and eliminate wasted labor. It has great effects such as being able to.
