Definitions

  • the present invention relates to a sheet member transporting apparatus configured to transport a sheet member subjected to printing along a transporting route including a curved route portion having a level difference in the direction of gravitational force, and a recording apparatus having the sheet member transporting apparatus.
  • an ink-jet printer is widely known as a recording apparatus configured to perform recording by causing a recording material to adhere to a sheet member.
  • a printer is configured to perform printing (image formation) on a sheet as the sheet member by ejecting ink (recording material) supplied to a recording head from nozzles formed in the recording head.
  • the sheet In the curved route portion having a level difference in the direction of gravitational force in a midsection of the transporting route as the U-turn transporting path described above, the sheet is transported while curving in the direction of gravitational force. Therefore, for example, when transporting a sheet having no elasticity, the sheet may fail to be transported because the sheet collapses under its own weight. Accordingly, in the case of the printer disclosed in JP-A-2006-197179, a plurality of pairs of rollers are provided in the U-turn transporting path, which is a curved route portion of the transporting route, to pinch the sheet at a plurality of positions along the U-turn transporting path and transport the sheet.
  • An advantage of some aspects of the invention is that a sheet member transporting apparatus in which increase in number of components is restrained to reduce time and effort for assembly even when a curved route portion having a level difference in the direction of gravitational force is provided in a midsection of a transporting route, and a recording apparatus having the sheet member transporting apparatus are provided.
  • a sheet member transporting apparatus configured to transport a flexible sheet member, including: a feeding device configured to feed the sheet member toward the downstream side in the direction of transport; a supporting device having a supporting member which is capable of supporting one of the surfaces of the sheet member fed by the feeding device, the supporting member being pivotable about a pivoting shaft extending along the width direction of the sheet member intersecting the direction of transport of the sheet member, and a transporting device configured to receive the sheet member pivoted together with the supporting member in a state of being supported by the supporting member of the supporting device from the supporting device and transport the sheet member toward the downstream side in the direction of transport.
  • the sheet member by the pivotal movement of the supporting member about the pivot shaft, the sheet member also pivots together with the supporting member in a state in which one of the surfaces thereof is supported by the supporting member, and is transported so as to draw a curved trajectory having a level difference in the direction of gravitational force. Therefore, even when the sheet member is transported along the transporting route including the curved route portion having a level difference in the direction of gravitational force, the sheet member can be transported irrespective of the elasticity thereof. Therefore, the sheet member can be transported without providing a mechanism such as a roller pair for pinching the sheet member in the transporting route, and hence increase in number of components is restrained to reduce time and effort for assembly.
  • the supporting member includes an abutting portion which is capable of coming into abutment with the sheet member fed by the feeding device at a downstream side end thereof in the direction of transport from an upstream side end thereof in the direction of transport.
  • the supporting member pivots as if it is pushed by the sheet member. Accordingly, even though a pivoting device for causing the supporting member to pivot is not provided specifically, the supporting member can be pivoted using the feeding force of the feeding device which feeds the sheet member.
  • the supporting member includes a curved surface portion which is capable of coming into surface contact with one of the surfaces of the sheet member.
  • the sheet member can be transported in a stable position in a state in which the curved surface portion of the supporting member and one of the surfaces of the sheet member in a state of being in surface contact with each other.
  • the probability of separation between the supporting member and the sheet member can be reduced by increasing a frictional force acting between the supporting member and the sheet member by securing a large contact surface area between the supporting member and the sheet member.
  • the transporting device includes a transporting roller extending along the width direction, and a rotating device configured to rotate the transporting roller, the supporting member is formed with a depression at a downstream side end in the direction of transport, and the depression opposes the transporting roller when the supporting member is pivoted toward the transporting device.
  • the supporting member is formed with the depression which opposes the transporting device when the supporting member is pivoted toward the transporting device. Therefore, part of the sheet member supported by the supporting member is positioned so as to oppose the depression and hence come into abutment with the transporting roller in association with the pivotal movement of the supporting member. Then, the sheet member is transported further toward the downstream side in the direction of transport so as to be entangled with the rotating transporting roller. Since the supporting member supports the sheet member with a portion where the depression is not formed at the downstream side end in the direction of transport at this time, the supporting member can transport the sheet member so as to push the sheet member toward the transporting roller.
