摘要:
An ink jet printer includes a print head having ink nozzles, which is movable in a direction across the feeding path. A supply mechanism is provided at one side of the feeding path, which supplies ink to the print head located in the ink supply station. A maintenance mechanism is provided at the other side of the feeding path, which operates a predetermined operation. The ink jet printer is further provided with a first clutch which transmits the rotation of the actuator to the supply mechanism only when the print head is located in the above-mentioned one side, and a second clutch which transmits the rotation of the actuator to the maintenance mechanism only when the print head is located in the above-mentioned the other side. With this, the supply mechanism and the maintenance mechanism are actuated by a common actuator.
摘要:
An ink jet recorder includes a recording head, a carriage for reciprocating the head, a sheet conveying roller, a motor for driving the roller, a maintenance mechanism and an ink supply mechanism. The driving force from the motor can be transmitted through a first clutch to the maintenance mechanism, and through a second clutch to the ink supply mechanism. One of the clutches is connected to a turn lever, and the other is connected to a shift lever. Each of the clutches can be switched mechanically by the carriage engaging with the associated lever. The single motive power source can drive a plurality of mechanisms. There is no need of a special switch for changing over the source.
摘要:
An elongated toner box extending in a horizontal direction has a cylindrical portion where a toner discharge port is formed. A wrapping member serving as a shutter is rotatably disposed over the cylindrical portion for selectively shutting off the toner discharge port. The wrapping member has a circular shape concentrical with the cylindrical portion. A developing case is provided to which the toner box is detachably installable. The developing case has a wall confronting the toner box, and a toner inlet port is formed at the wall. A toner inlet shutter is slidably movably supported to the partition wall. When the wrapping member opens and closes the toner discharge port, the wrapping member is positioned close to the outer surface of the toner box and does not largely protrude from the toner box. Further, the discharge port shutter and the inlet port shutter are movable in interlocking relation with each other.
