Ink cartridge and printer

摘要

An ink cartridge is adapted to be mounted in a holder of a printer, and includes first to third surfaces and a pressing section. The first and second surfaces face each other. The third surface has first and second end sections respectively adjacent to the first and second surfaces. The pressing section presses the ink cartridge to a second surface side when the ink cartridge is mounted in the holder. The third surface has a detection section which optically detects a remaining state of ink in the ink cartridge, and an abutting section which abuts against the holder. A distance between the detection section and the second end section is shorter than a distance between the detection section and the first end section in the third surface, and the abutting section is positioned between the detection section and the second end section.

主权项

1. An ink cartridge configured to be mounted in a mounting direction into a holder of a printer, the ink cartridge comprising:
a first surface; a second surface facing the first surface; a third surface having a first end section adjacent to the first surface and a second end section adjacent to the second surface; and a pressing section provided in the first surface and pressing the ink cartridge toward a second surface side when the ink cartridge is mounted in the holder, the third surface having
a detection section configured and arranged to optically detect a remaining state of ink which is contained in the ink cartridge, andan abutting section protruding from the third surface so that a distal end surface of the abutting section abuts against the holder in the mounting direction in order to make a space between the holder and another section of the third surface other than the abutting section when the ink cartridge is mounted in the holder, wherein a distance between the detection section and the second end section is shorter than a distance between the detection section and the first end section in the third surface, and the abutting section is positioned between the detection section and the second end section.
