Abstract:
1. A liquid dispensing apparatus comprising: a head that dispenses a liquid containing a sedimentary substance; a liquid tank for storing the liquid; a liquid supply path through which the liquid is supplied from the ink tank to the head via a section having a level difference larger than a predetermined distance in a vertical direction, the section with the level difference including one or more bent portions including a bent portion of a first type where a downward flow of the liquid is turned to an upward flow; a bent shape conversion unit configured to change a shape of the liquid supply path with respect to the section with the level difference, so as to convert the bent portion of the first type in the section with the level difference before the shape conversion, into a bent portion of a second type where an upward flow of the liquid is turned to a downward flow; and a control unit configured to cause the bent shape conversion unit to perform the shape conversion and restore the initial shape of the liquid supply path by reverse conversion of the shape of the liquid supply path after the shape conversion.
