    • A stencil printing apparatus is provided, which comprises a pressure chamber the wall of which is partly constituted by a flexible sheet member, a mount which is disposed in the pressure chamber opposite to the flexible sheet member and on which an article to be printed is placed, a frame for supporting a stencil between the flexible sheet member and the mount, and a pump for reducing pressure in the pressure chamber, in which the pump for reducing pressure is an air pump which comprises a cylinder connected to the pressure chamber and a piston slidably disposed in the cylinder. Stencil printing can be quickly and readily effect by pressure reduction in the pressure chamber. The printing apparatus can be small-sized, lightweight and simplified as a whole, and is improved in operatability.
    • 提供了一种模版印刷设备,其包括压力室,其壁的一部分由柔性片状构件构成,安装件设置在与柔性片构件相对的压力室中,并且待放置物品 用于支撑柔性片状构件和安装件之间的模版的框架以及用于减小压力室中的压力的​​泵,其中用于减压的泵是包括连接到压力室的气缸和活塞 可滑动地设置在气缸中。 模版印刷可以通过压力室中的压力降低而快速而容易地实现。 打印装置整体上可以小型化,轻量化,简化,可操作性提高。

    • The disclosed stencil printing apparatus includes, a pressure chamber comprising a first place member on which a sheet to be printed is placed, an airtight elastic frame which is placed on the first plate to surround the sheet, and a second plate member which is placed on the elastic frame and supports a stencil opposite to the sheet; a resilient air chamber which is layered below the first plate member of the pressure chamber and communicates with the pressure chamber; and a check valve which allows air to be exhausted from the air chamber but inhibits the air chamber from sucking air from the apparatus outside. Stencil printing can be effected by placing a stencil printing ink on a stencil, disposing a stencil and a sheet to be printed in the pressure chamber, compressing the air chamber to exhaust air to the outside and then releasing the compression of the air chamber while the air chamber is kept sealed from the outside, so that the pressure chamber is depressurized so as to allow the pair of plate members to come close to each other and simultaneously bring the stencil into close contact with the sheet to transfer the ink to the sheet through the suction created as the air chamber restores its shape. The printing apparatus can quickly and readily depressurize the pressure chamber, is small-sized, lightweight and simplified as a whole, and is improved in operatability.
    • 所公开的模版印刷设备包括:压力室,包括放置有待印刷的片材的第一位置构件;放置在第一板上以围绕片材的气密弹性框架;以及第二板构件, 弹性框架并支撑与片材相对的模板; 弹性空气室,其层压在所述压力室的所述第一板构件的下方并与所述压力室连通; 以及止回阀,其允许空气从空气室排出,但是阻止空气室从设备外部吸入空气。 模版印刷可以通过将蜡纸印刷油墨放置在模板上,将待印刷的模板和片材设置在压力室中,压缩空气室以将空气排出到外部,然后释放空气室的压缩 空气室从外部保持密封,使得压力室被减压以允许一对板构件彼此靠近并同时使模板与片材紧密接触以将油墨转移到片材通过 作为空气室产生的吸力恢复其形状。 打印装置能够快速且容易地对压力室进行减压,整体尺寸小,重量轻,简化,可操作性提高。
