Ink cartridge and ink jet recorder using ink cartridge

Abstract

Abstract PURPOSE:To prevent erroneous mounting of a ink cartridge by providing a protrusion on part of a cartridge crossing at right angles with the latter's mounting direction and forming a groove in which said protrusion is fitted in freely slidable fashion inward from the open edge of an opening. CONSTITUTION:If an ink cartridge 3 is held by hand with a power supply switch set ON and fitted in an opening 15 without considering its lateral or vertical position, CPU decides whether the switch 16 is set ON. If an embossed ribbon 3a is fitted in a groove 15a in correct position, the former is set ON contacting the switch 16, then in 'standby position' for recording. In the meantime, if the embossed ribbon 3a is not fitted into the groove 15a, the switch 16 is not set ON, turning an alarm lamp ON. After this, if the ink cartridge 3 is correctly attached again, the switch 16 is to be set ON, turning the alarm lamp OFF.
