Title:
INKJET RECORDING APPARATUS
Document Type and Number:
Japanese Patent JP2010052253
Kind Code:
A
Abstract:

To certainly make a fixed volume of ink move to a recording head side from the inside of a supply pipe.

An inkjet printer makes a sphere 35, capable of moving only in the space 34 of a tube 31b by having it move from the movement starting position to the movement ending position, by making a magnet 37 move, which is arranged near the exterior of the tube 31b. Then, since the ink hardly flows from the minute clearance between the sphere 35 and the inner wall of the tube 31b, the inkjet printer is able to move the fixed volume of ink existing between the movement starting position and the movement ending position to the inkjet head side. When open cells pile up in the downstream side of the sphere 35, the inkjet printer makes the magnet 37 face the sphere 35 move two or more times in the right and left sides, and then makes the open cells which have been piled up in the downstream of the sphere 35 emerge in the upper part of the space 34 and eject it by purging operation, or the like.
