Abstract

A cartridge detachably mounted to a printing device cartridge mounting portion includes a second fixing structure including a groove guiding a first fixing structure, and a locking portion provided to the groove. The cartridge is brought from a cartridge insertion state to a cartridge mounting portion predetermined position by being moved along a horizontal direction to a mounting state in which the cartridge is mounted by being rotated and moved in a rotation mounting direction around a fulcrum which is a far side of the cartridge mounting portion in the insertion direction by receiving a force having a component in a downward direction of a gravity direction. The second fixing structure locks the first fixing structure in the mounting state and releases with the first fixing structure by receiving the force having the component in the downward direction of the gravity direction applied to the cartridge in the mounting state.

Dependent claims

A cartridge configured to be detachably mounted to a cartridge mounting portion of a printing device, the cartridge comprising:

a second fixing structure including
a groove which has a loop shape and which is configured to guide a first fixing structure of the printing device, and
a locking portion provided to the groove and configured to lock the first fixing structure, wherein
the cartridge is configured to be brought from an insertion state to a mounting state, the insertion state being a state in which the cartridge is inserted to a predetermined position of the cartridge mounting portion by being moved in an insertion direction along a horizontal direction, the mounting state being a state in which the cartridge is mounted in the cartridge mounting portion by being rotated and moved in a rotation mounting direction around a rotation fulcrum which is a far side of the cartridge mounting portion in the insertion direction by receiving a force having a component in a downward direction of a gravity direction,
the second fixing structure is configured to lock the first fixing structure in the mounting state, and
the second fixing structure is configured to release locking with the first fixing structure by receiving the force having the component in the downward direction of the gravity direction which is applied to the cartridge in the mounting state.
