Inkjet recording apparatus and ink cartridge
First Claim
1. An inkjet recording apparatus having a recording head that receives supply of ink from an ink cartridge installed in a cartridge accommodation region, the ink cartridge having a first member constituting a one-push type fixing member formed on the ink cartridge, the inkjet recording apparatus comprising:
- a second member that constitutes another one-push type fixing member cooperating with the first member, and that is formed in a position facing a plane that is substantially parallel to an insertion direction in which the ink cartridge is inserted into the cartridge accommodation region, whereby the ink cartridge is held by the first and members in a predetermined position in a state in which the ink cartridge is resiliently urged by a resiliently urging member in a direction opposite to the insertion direction,wherein the first member constituting the one-push type fixing member includes a protrusion whose range of motion is restricted, andwherein the second member includes a combination of a guide path for guiding the protrusion in one direction, and a holding portion engaging the protrusion.

Abstract
There is disclosed an ink cartridge capable of being removably held in an ink cartridge accommodation portion simply by pushing in the cartridge in an insertion direction. The ink cartridge (5) is mounted on a carriage (4) having a cartridge accommodation region. A one-push type fixing member (30) in a position facing a surface parallel to an insertion direction in which the cartridge is inserted into the cartridge accommodation region is engaged with a fixing protrusion (12a) forming another one-push type fixing member and cooperating with the first-mentioned one-push type fixing member, so that the cartridge (5) is held in a predetermined position in a state in which the cartridge is resiliently urged by a spring (24) in a direction opposite to the insertion direction.
