Abstract:
1. A printing material holding container for mounting detachably on a printing material holding container mounting unit in a printing device 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, and a device side terminal unit, 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; a printing material injection port provided on the case, communicating with the printing material holding portion; a recess which is provided in a corner portion at which the front surface and the first side surface intersect each other and into which the device side terminal unit is inserted in the mounted state, wherein the recess includes an opening which is an entrance when the device side terminal unit is inserted into the recess, and a first side wall, a second side wall, and a bottom wall that constitute at least a part of an inner wall of the recess, the first side wall and the second side wall oppose each other in the X axis direction, and the first side wall is positioned on the +X axis direction side and the second side wall is positioned on the −X axis direction side, the bottom wall is tilted in a direction including a −Y axis direction component and a +Z axis direction component and has a tilted surface provided with a container side terminal group having contact portions that come into contact with the device side terminal group in the mounted state, the first side wall is provided with a first restriction portion which restricts movements in the +Z axis direction and the +X axis direction of the device side terminal unit by coming into contact with the first positioning portion in the +Z axis direction and the +X axis direction in the mounted state, and the second side wall is provided with a second restriction portion which restricts movements in the +Z axis direction and the −X axis direction of the device side terminal unit by coming into contact with the second positioning portion in the +Z axis direction and the −X axis direction in the mounted state.
