Apparatus for attaching and detaching ink cartridge, recorder comprising the same and liquid spraying apparatus comprising the same

An ink-cartridge attaching and detaching device for sliding an ink cartridge and mounting the ink cartridge on a main body of a recording apparatus, the ink-cartridge attaching and detaching device comprising:

• a cartridge holding unit configured to hold the ink cartridge by insertion of the ink cartridge by a first predetermined stroke;
• and
• a power transmitting and converting mechanism configured to ensure a pressing force required for mounting the ink cartridge by leverage by turning of a lever arm and to convert the turning of the lever arm into motion of a second predetermined stroke required for mounting the ink cartridge while held by the cartridge holding unit,
• wherein the cartridge holding unit includes:
• a slider configured to move in response to a power from the power transmitting and converting mechanism;
• an engagement member configured to engage with the slider, swing with respect to the slider, engage with the ink cartridge, hold the ink cartridge, and move in the mounting direction together with the slider;
• a first engagement unit configured to operate such that the slider and the engagement member directly engage with each other when the engagement member swings;
• and
• a second engagement unit configured to operate such that the slider and the engagement member directly engage with each other when the engagement member mounts the ink cartridge.

A liquid ejecting apparatus including a liquid-cartridge attaching and detaching device for sliding a liquid cartridge and mounting the liquid cartridge on a main body of the liquid ejecting apparatus, the liquid ejecting apparatus comprising:

• a cartridge holding unit configured to hold the liquid cartridge by insertion of the liquid cartridge by a first predetermined stroke;
• and
• a power transmitting and converting mechanism configured to ensure a pressing force required for mounting the liquid cartridge by leverage by turning of a lever arm and to convert the turning of the lever arm into motion of a second predetermined stroke required for mounting the liquid cartridge while held by the cartridge holding unit,
• wherein the cartridge holding unit includes an integrated engagement member configured to engage with a surface of the liquid cartridge, the surface being parallel to a mounting direction, and
• wherein, when engaging with the liquid cartridge, the engagement member lies in a central portion in a width direction with respect to the mounting direction at the surface.

A liquid ejecting apparatus including a liquid-cartridge attaching and detaching device for sliding a liquid cartridge and mounting the liquid cartridge on a main body of the liquid ejecting apparatus, the liquid ejecting apparatus comprising:

• a cartridge holding unit configured to hold the liquid cartridge by insertion of the liquid cartridge by a first predetermined stroke;
• and
• a power transmitting and converting mechanism configured to ensure a pressing force required for mounting the liquid cartridge by leverage by turning of a lever arm and to convert the turning of the lever arm into motion of a second predetermined stroke required for mounting the liquid cartridge while held by the cartridge holding unit,
• wherein the cartridge holding unit includes:
• a slider configured to move in response to a power from the power transmitting and converting mechanism;
• an engagement member configured to engage with the slider, swing with respect to the slider, engage with the liquid cartridge, hold the liquid cartridge, and move in the mounting direction together with the slider;
• a first engagement unit configured to operate such that the slider and the engagement member directly engage with each other when the engagement member swings;
• and
• a second engagement unit configured to operate such that the slider and the engagement member directly engage with each other when the engagement member mounts the liquid cartridge.
