摘要:
A suction recovery device of ink jet recording apparatus comprises a cap which can contact with or separate from a face formed with discharge ports for recording by discharging the ink, the cap communicating to a suction system for performing the suction recovery through the discharge ports via the cap, said cap having a groove portion for guiding ink, and formed of an elastic material integrally with an ink communication member for communicating to the suction system via a suction port provided on an inner wall of the cap, and said suction system having a cylinder and a piston reciprocating within the cylinder, and having disposed ink absorbing member in an ink exhaust portion within the cylinder.

A pump mechanism of an ink jet recording apparatus comprises a pump having a suction portion for sucking from a sucked member, said pump switching between the suction and non-suction operation of the suction portion by a reciprocating motion of a piston within a cylinder, without having a valve, a carrying member connected to said pump for carrying waste ink from said pump said carrying member opening to the atmosphere and a prevention mechanism for preventing a backflow of ink within said pump from the suction portion of said pump, to the outside of said pump which is caused by the reciprocating motion of the piston said prevention mechanism being an internal pump mechanism.

Ink jet recording apparatus including a carriage having a mounting portion for an ink jet recording head for performing recording on a recording medium by ejecting ink from the ink discharging ports to allow the ink jet recording head to travel in given directions, and a recovery mechanism for preventing disabled ejection of the ink jet recording head, which is provided with a driving force transmission mechanism capable of performing positional displacement to a first position for transmitting a driving force from a driving power source to the carriage and to a second position for transmitting the driving force from the driving power source to the recovery mechanism. The recovery mechanism includes a pump mechanism having a piston shaft within a cylinder with a pistion and a sealing member slidably fitted on the piston, where the cylinder, pistion and sealing member define a space for generating a pressure change in a cap.

In an image forming apparatus, a driving force transmitting member includes a protruding portion that can be removably attached to a concave portion of a toner bottle in a shaft line direction of a rotation shaft. The concave portion and the protruding portion can transmit a rotation driving force of the rotation shaft to the toner bottle by being connected with each other such that the concave portion and the protruding portion cannot be rotated relative to each other. A phase detection member includes a pin inserting hole that can select an attachment phase relative to the rotation shaft and can be fixed such that the phase detection member cannot be rotated relative to the rotation shaft.

In an image forming apparatus, a driving force transmitting member includes a protruding portion that can be removably attached to a concave portion of a toner bottle in a shaft line direction of a rotation shaft. The concave portion and the protruding portion can transmit a rotation driving force of the rotation shaft to the toner bottle by being connected with each other such that the concave portion and the protruding portion cannot be rotated relative to each other. A phase detection member includes a pin inserting hole that can select an attachment phase relative to the rotation shaft and can be fixed such that the phase detection member cannot be rotated relative to the rotation shaft. When attaching the protruding portion to the concave portion and removing the protruding portion from the concave portion, a control unit controls a motor to stop a rotation phase of the phase detection member at a prescribed phase. When attaching the protruding portion to the concave portion and removing the protruding portion from the concave portion, a bottle upper surface cover regulates the toner bottle such that a rotation phase of the toner bottle is located at a prescribed phase.
