This application is based on Japanese Patent Application Nos. 2000-118564 filed Apr. 19, 2000 and 2000-123295 filed Apr. 24, 2000, the content of which is incorporated hereinto by reference.
1. Field of the Invention
The present invention relates to a joint device, an ink jet apparatus having the joint device, and an ink supplying device and method.
FIG. 1 is a sectional view of a recording apparatus according an embodiment of the present invention;
FIG. 2 is a sectional view taken along line II—II in FIG. 1;
FIG. 3 is an enlarged front view of a storage ink tank section in FIG. 2;
Embodiments of the present invention will be described below in detail with reference to the drawings.
FIGS. 1 and 2 are views useful in explaining the entire ink jet recording apparatus in which a joint device according to the present invention is used. In this application, the ink jet recording apparatus operates based on a serial scan method with which a recording head moves in a main scan direction.
In FIG. 1, the ink jet recording apparatus of the present invention principally comprises a feeding device section 1 for feeding recorded media S, a recording device section 2 performing a recording operation, an ink refilling device section 3 for executing ink refilling, a cap device section 30 (see FIG. 6) or the like, as shown in the drawing. The configurations of the feeding device section 1, the recording device section 2, and the ink refilling device 3 will be separately explained below.
