Abstract:
1. A printing material holding container for mounting detachably on a printing material holding container mounting unit that comprises a printing material supply tube fixed to a device side front wall part, and having a central axis extending in a designated direction, a rod shaped member having an axis parallel to the central axis, that is movable along the axis direction, provided on the device side front wall part, and a sensor for detecting displacement of the rod shaped member, the printing material holding container comprising: a case for which when three mutually orthogonal spatial axes are the X axis, the Y axis, and the Z axis, the directions along the X axis, the Y axis and the Z axis are the X axis direction, the Y axis direction, and the Z axis direction, the direction for which the printing material holding container is inserted in the printing material holding container mounting unit is the −Y axis direction, and the direction for which the printing material holding container is removed from the printing material holding container mounting unit is the +Y axis direction, the case comprises: two surfaces facing opposite in the Y axis direction, being a front surface positioned at the −Y axis direction side, and roughly rectangular in shape with the Z axis direction dimension larger than the X axis direction dimension, and a back surface positioned at the +Y axis direction side, two surfaces that intersect with the front surface and the back surface and face opposite in the Z axis direction, being a first side surface positioned at the +Z axis direction side, and a second side surface positioned at the −Z axis direction side, and two surfaces that intersect with the front surface, the back surface, the first side surface, and the second side surface, facing opposite in the X axis direction, being a third side surface positioned at the +X axis direction side, and a fourth side surface positioned at the −X axis direction side, a printing material holding portion provided inside the case, a first insertion hole provided on the front surface, for which a printing material supply port in which the printing material supply tube is inserted is arranged in the interior, and also in which the printing material supply tube is inserted, a second insertion hole provided on the front surface in which the rod shaped member is inserted, a printing material flow path having the printing material supply port at one end, and for which the other end is connected to the printing material holding portion, and a printing material injection flow path having a printing material injection port that opens to another surface excluding the front surface at one end, and for which the other end is connected to the printing material holding portion, wherein of the front surface, the second insertion hole is provided at an intermediate position between the first side surface and the second side surface.
