  • Publication number: 20250135787
    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.

  • Patent number: 8580427
    Abstract: In this assembled battery, connections between electrode terminals of electrical cells and connection members for the electrode terminal are reliably maintained for a long period of time. The electrode terminal is formed in a tapered pillar shape whose width decreases from the front end of the electrode terminal toward a battery case. Also, a groove, which is shaped from the front end toward the battery case and divides at least a portion of the front end into segmented portions, is provided to the electrode terminal. The segmented portions are elastically deformable to move close to or away from each other. The bus bar (connection member for the electrode terminals) includes a through-hole whose width decreases from the front end of the electrode terminal toward a battery case. The bus bar is fitted to the electrical terminal, by elastically deforming and moving the segmented portions close to each other.
