Printing apparatus and cartridge

摘要

The printing fluid supply apparatus comprises the printing fluid cartridge and a cartridge accommodating portion. The cartridge accommodating portion comprises a casing, and an engage member. The printing fluid cartridge comprises a main body including a chamber, an ink outlet portion, an engage portion, a contact portion, and a biasing member. The contact portion allows the engage member to rotate toward the first position by contacting with the engage member and allows the biasing member to make elastic deformation while the printing fluid cartridge installing to the casing. The engage member in the first position engages the engage portion, and the printing fluid cartridge is held in an accommodated position against the biasing portion when the printing fluid cartridge is achieved to the accommodated position in the casing. The biasing portion allows the printing fluid cartridge being held in the casing to move opposite to the insertion direction when the engage member rotates to the second position.

1. A printing apparatus, comprising:
a casing configured to accept a cartridge; an engage member configured to rotate between a first position and a second position; and a biasing member attached to the cartridge, and configured to provide a biasing force against the engage member, wherein when the engage member is in the first position, the biasing force locks the cartridge in the casing in a first direction, and wherein when the engage member is in the second position, the biasing force urges the engage member in the first direction and the cartridge in a second direction, opposite the first direction, to eject the cartridge from the casing.
