Flow path opening/closing device and inkjet recording apparatus provided with the flow path opening/closing device

摘要

A flow path opening/closing device includes a tube through which a recording liquid flows, a tube support member on which the tube is mounted, an opening/closing member configured to rotate between a closing position and an opening position, and an elastic support member. In the closing position, the opening/closing member crushes the tube mounted on the tube support member, thereby cutting off a flow path defined within the tube. In the opening position, the opening/closing member allows the cutoff of the flow path to be cancelled by a restoring force of the tube. The elastic support member elastically supports the tube support member so as to move the tube support member toward and away from the opening/closing member.

主权项

1. A flow path opening/closing device comprising:
a tube through which a recording liquid flows; a tube support member on which the tube is mounted; an opening/closing member configured to move between a closing position in which the opening/closing member crushes the tube mounted on the tube support member and cuts off a flow path defined within the tube and an opening position in which the cutoff of the flow path is cancelled by a restoring force of the tube; wherein the tube support member and the opening/closing member have the tube therebetween and are arranged to oppose to each other in a radial direction of the tube; an elastic support member configured to elastically support the tube support member in the radial direction so as to move toward and away from the opening/closing member; and a drive unit configured to drive the opening/closing member, the drive unit including a rotary cam member, the opening/closing member being linearly driven by the rotary cam member so as to move toward and away from the tube support member.
