Ink-supply control device and stencil printing machine having the same

摘要

In a stencil printing machine, when quantity of ink supplied into an ink supplying section in a rotary cylindrical drum is smaller than a predetermine value, ink complementing means is driven to supply ink from an ink storing container into the ink supplying section, and when the quantity of ink in the ink supplying section does not reach the predetermined value within an ink-complementing-means operation time, a determination is made that no ink is left in the ink storing container, and a warning signal is produced. The stencil printing machine comprises: a quantity-of-ink detector for detecting whether or not the quantity of ink in the ink supplying section has reached the predetermined value; a kind-of-ink detector for detecting the kind of ink supplied into the ink supplying section in the rotary cylindrical drum; and controller which operates to change, according to the kind of ink detected by the kind-of-ink detector, the ink-complementing-operation time which elapses until a determination is made that no ink is left in the ink storing container.
