Printing fluid supply device and printing fluid cartridge

A printing fluid cartridge configured to be inserted into a cartridge mounting portion in an insertion direction which is aligned with a first direction, the cartridge mounting portion comprising a connection portion, a first sandwiching piece supporting a contact, and a second sandwiching piece, the cartridge comprising:

• a cartridge body comprising a printing fluid chamber configured to store printing fluid therein;
• a printing fluid supply portion provided at the cartridge body and extending along the first direction, wherein the printing fluid supply portion is configured to be connected to the connection portion, such that the printing fluid is allowed to flow out of the printing fluid chamber through the printing fluid supply portion;
• an electric interface configured to contact the contact supported by the first sandwiching piece;
• and
• a support member comprising a support surface facing in a first sub direction and a rear surface positioned opposite the support surface and facing in a second sub direction opposite the first sub direction, wherein the first sub direction and the second sub direction constitute a second direction which is perpendicular to the first direction, wherein the electric interface is provided at the support surface,
• wherein the cartridge body has a first space and a second space formed therein, wherein the first space is opened in the insertion direction so as to receive the first sandwiching piece therein, and the second space is opened in the insertion direction so as to receiver the second sandwiching piece therein, wherein the support surface of the support member faces the first space and the rear surface of the support member faces the second space, wherein the cartridge body is configured to hold the support member such that the support member is movable relative to the cartridge body in the second direction.
