System for consuming consumable material stored in cartridge

A system comprising:

• a cartridge configured to accommodate a consumable material;
• a cartridge attachment section, the cartridge being inserted into and attached to the cartridge attachment section in a first direction, the cartridge being removed from the cartridge attachment section in a second direction opposite to the first direction;
• and
• a consuming section including a recording head and configured to consume the consumable material stored in the cartridge completely attached to the cartridge attachment section,
• the cartridge comprising:
• a board supporting portion;
• a board supported by the board supporting portion, the board having a mount surface and a supported surface opposite to the mount surface, the mount surface facing in a third direction perpendicular to the first direction and the second direction, the supported surface facing in a fourth direction opposite to the third direction and supported by the board supporting portion, the board and a portion of the board supporting portion defining a moving trajectory during insertion and removal of the cartridge relative to the cartridge attachment section;
• and
• an electrical interface mounted on the mount surface of the board,
• the cartridge attachment section comprising:
• a slider configured to contact at least one of the board and the board supporting portion of the cartridge, the slider being movable between a first position and a second position and between a first posture and a second posture in accordance with insertion and removal of the cartridge relative to the cartridge attachment section, the second position being displaced in the third direction relative to the first position, the slider at the first position being in the first posture and the slider at the second position being in the second posture;
• an electrical contact provided on the slider and configured to contact the electrical interface of the cartridge, the electrical contact being movable between a contact position and a non-contact position in accordance with the movement of the slider between the first posture and the second posture;
• a first wall provided on the slider at a position offset in the first direction relative to the electrical contact, the first wall having a portion that overlaps the moving trajectory of the board and the portion of the board supporting portion during insertion and removal of the cartridge relative to the cartridge attachment section;
• a second wall provided on the slider at a position offset in the second direction relative to the electrical contact;
• and
• a biasing member configured to apply a biasing force to the slider in the second direction,
• wherein:
• when the slider is at the first position and in the first posture,
• the electrical contact is in the contact position and overlaps the electrical interface of the cartridge completely attached to the cartridge attachment section, the second wall having a portion overlapping the moving trajectory;
• when the slider is in the second posture,
• the electrical contact is in the non-contact position displaced in the third direction relative to the contact position, the second wall being displaced in the third direction relative to the moving trajectory;
• and
• when the cartridge has been completely attached to the cartridge attachment section,
• the cartridge and the cartridge attachment section define a first space therebetween at a position offset in the first direction relative to the board and the portion of the board supporting portion, the first wall being received in the first space;
• and
• the cartridge and the cartridge attachment section define a second space therebetween at a position offset in the second direction relative to the board and the portion of the board supporting portion, the second wall of the slider at the first position and in the first posture being received in the second space.
