Abstract:
1. A cartridge for use in a printing device with a printing material supply pipe, the printing material supply pipe having a filter and being formed with an elongated shape in a depth direction, the cartridge being rotated when mounted into the printing device, the cartridge comprising: a first surface and a second surface which oppose each other; a third surface and a fourth surface which intersect with the second surface and the first surface and which oppose each other; a fifth surface and a sixth surface which intersect with the first surface to the fourth surface and which oppose each other, when a distance between the first surface and the second surface is height, a distance between the third surface and the fourth surface is depth, and a distance between the fifth surface and the sixth surface is width, the depth being larger than the height and the height being larger than the width; and a printing material supply port provided in the first surface, and configured and arranged to be connected to the printing material supply pipe of the printing device, the printing material supply port including a filter that contacts the filter of the printing material supply pipe when the cartridge is mounted in the printing device, the depth of the cartridge being aligned with the depth direction of the printing material supply port when the cartridge is mounted in the printing device, an effective area of the filter of the printing material supply port being the same or more and being five times or less than an effective area of the filter of the printing material supply pipe, and effective dimension of the filter of the printing material supply port in a depth direction being greater than effective dimension of the filter of the printing material supply port in a width direction.
