Patent ID: 8235498

Claim:
A head repairing apparatus for repairing a liquid ejecting head of a liquid ejecting apparatus which ejects liquid from a liquid ejecting nozzle provided on a head surface of the liquid ejecting head to a ejection object, comprising: one or two more maintenance units which are supported by an apparatus base body so as to be displaceable in a predetermined displacement direction becoming a direction intersecting the head surface of the liquid ejecting head, wherein the maintenance units have a unit base portion that is supported by the apparatus base body so as to be displaceable in the displacement direction; a seal member capable of sealing the head surface of the liquid ejecting head; a suction pump capable of sucking a suction path that communicates with the sealing surface of the seal member; an atmosphere communication path in which one side thereof communicates with the sealing surface of the seal member and the other side thereof is opened to atmosphere; an atmosphere opening valve capable of opening and closing the atmosphere communication path; a push latch mechanism for performing the opening and closing operation of the atmosphere opening valve; a push latch cam which is engaged with an operation portion of the push latch mechanism and can perform a pushing movement operation of the operation portion; a wiper support member which is supported by the unit base portion so as to be displaceable in the displacement direction; a wiper attached to the wiper support member; a wiper support member cam which is engaged with the wiper support member to displace the wiper support member in the displacement direction; and a driving force transmission mechanism for transmitting the driving force of a driving force source, wherein the driving force transmission mechanism includes a pump driving force transmission mechanism which transmits the driving force of the driving force source to the suction pump; a sun gear to which the driving force of the driving force source is transmitted so as to be rotated; a rolling arm in which a rolling range thereof is limited to a certain range and which is pivotally supported on a rotation axis of the sun gear; a planetary gear which is rotatably supported by the rolling arm and is engaged with the sun gear; and an intermittence gear which is engaged with the planetary gear in a range in which teeth are formed; wherein, the push latch cam is provided so as to be rotatable integrally with the intermittence gear, a cam driving gear for rotating the wiper support member cam rotates in connection with the rotation of the intermittence gear, and in a range in which the intermittence gear is engaged with the planetary gear, so that the intermittence gear can be rotated, a rotation range of the intermittence gear capable of opening and closing the atmosphere opening valve by the push latch mechanism and a rotation range of the intermittence gear in which the wiper is displaced by the rotation of the wiper support member cam are set in non-overlapped positions.
