Sheet conveyer device and inkjet recording apparatus

An inkjet recording apparatus comprising:

• a chassis defining a first conveyer path, in which a sheet is conveyed in a conveying direction, and a second conveyer path, in which the sheet is conveyed and guided to reenter the first conveyer path;
• and
• a conveyer device comprising:
• a pair of path members arranged to oppose to each other and define a part of the first conveyer path;
• a flapper disposed along the first conveyer path at a joint point, at which the first conveyer path and the second conveyer path are jointed, the flapper being configured to be pivotable among a first condition, in which the flapper blocks the first conveyer path and guides the sheet being conveyed in a reverse direction opposite from the conveying direction to the second conveyer path, a second condition, in which the flapper allows the sheet being conveyed in the conveying direction to pass thereby, and a third condition, in which the flapper is separated from an opposing member arranged to oppose to the flapper, the opposing member being arranged to contact the flapper when the flapper is in the first condition;
• an urging member configured to urge the flapper toward the first condition;
• and
• a movable member including first and second pieces spaced apart from one another and positioned such that the flapper is situated between the first and second pieces, the movable member configured to be movable between a first position, in which the flapper in the first condition is contactless from the movable member, and a second position, in which the movable member contacts the flapper and moves the flapper to pivot from the first condition to the third condition, the movable member being configured to separate one of the pair of path members from the other of the pair of path members when the movable member moves from the first position to the second position,
• wherein the pair of path members comprises:
• a platen configured to support the sheet in the first conveyer path;
• and
• a recording unit arranged along the first conveyer path to oppose to the platen, the recording unit being configured to discharge ink at the sheet supported on the platen, and
• wherein the movable member moving from the first position to the second position separates one of the platen and the recording unit from the other of the platen and the recording unit.
