Definitions

  • the present disclosure relates to a cartridge accommodating device to which a cartridge is attachable, and also to a system including the cartridge accommodating device and the cartridge.
  • the conventional cartridge accommodating device includes a connector, and the cartridge is provided with a circuit board.
  • an electrical interface formed on the circuit board of the cartridge comes into contact with an electrical contact provided at the connector of the cartridge accommodating device. With this contact between the electrical interface and the electrical contact, information stored in an IC mounted on the circuit board of the cartridge can be transmitted to the cartridge accommodating device.
  • the electrical interface of the cartridge keeps slidingly moving against the electrical contact of the connector until completion of the attachment of the cartridge to the cartridge accommodating device once the electrical interface of the cartridge is brought into contact with the electrical contact of the connector. As a result, resistance applied to the cartridge during the insertion thereof may become greater than otherwise.
  • the connector of the cartridge accommodating device may be designed to be movable, as disclosed in Japanese Patent Application Publication No. 2017-052220 , for example.
  • the connector is allowed to move to a position where the electrical contact thereof is separated from the electrical interface of the cartridge during insertion of the cartridge into the cartridge accommodating device, and then to a position where the electrical contact makes contact with the electrical interface of the cartridge upon completion of the attachment of the cartridge to the cartridge accommodating device.
  • a connecting member such as a flexible flat cable, is necessary to connect the connector to the cartridge accommodating device.
  • a complicated structure is therefore required for the cartridge accommodating device.
  • the position of the electrical contact belonging to the movable connector may become unstable.
  • EP 3 386 759 A1 discloses a cartridge accommodating device comprising a holder, a connector, the connector comprising a housing and a conductive member which comprises a leaf spring.
  • a cartridge accommodating device that can stabilize a position of an electrical contact provided at a movable connector, without necessitating a complicated structure; and a system including the cartridge accommodating device and a cartridge attachable thereto.

  • a direction opposite to the frontward direction 51, i.e., a direction in which the ink cartridge 30 is removed from the cartridge attachment section 110 is defined as a rearward direction 52.
  • Th frontward direction 51 and rearward direction 52 are parallel to a horizontal direction orthogonal to the gravitational direction and parallel to the insertion direction of the ink cartridge 30 in the present embodiment. Hence, the frontward direction 51 and rearward direction 52 cross the gravitational direction.
  • the gravitational direction is defined as a downward direction 53
  • a direction opposite to the gravitational direction is defined as an upward direction 54.
  • directions orthogonal to the frontward direction 51 and rearward direction 52 are defined as a rightward direction 55 and a leftward direction 56, respectively.

  • frontward direction 51 and rearward direction 52 may also be collectively referred to as a front-rear direction;
  • the upward direction 54 and downward direction 53 may also be collectively referred to as an up-down direction;
  • the rightward direction 55 and leftward direction 56 may also be collectively referred to as a left-right direction, whenever appropriate.
