Printer and sheet support device
According to an embodiment, a printer includes: a pair of support shafts that are supported by the casing, inserted into an inner periphery of an ink ribbon wound into a cylinder, and support the ink ribbon hung around a printing device. The printer further includes a driven shaft that is connected to one end of each of the support shafts so as to be movable along a longitudinal direction of the corresponding support shaft. The printer further includes a transmitter that is driven to rotate to transmits rotation to the driven shaft pressed by biasing of the biasing member.
1 . A printer, comprising:
a holding device that holds a wound strip of paper;
a printing device that prints paper pulled from the holding device;
a casing that contains the holding device and the printing device;
a pair of support shafts that are supported by the casing, inserted into an inner periphery of an ink ribbon wound into a cylinder, and support the ink ribbon hung around the printing device;
a driven shaft that is connected to one end of each of the support shafts so as to be movable along a longitudinal direction of the corresponding support shaft;
a biasing member that biases the driven shaft in a direction away from the support shaft;
a transmitter that is provided to the casing and driven to rotate to transmit rotation to the driven shaft pressed by biasing of the biasing member; and
an attachment that is attachable/detachable to/from the support shaft, is long in the longitudinal direction of the support shaft, and covers an outer periphery of the support shaft.
2 . The printer according to claim 1 , wherein
the attachment includes a bent portion whose cross section orthogonal to the longitudinal direction is substantially U-shaped.
3 . The printer according to claim 2 , wherein
the attachment includes a compression contact member that is provided on an outer periphery of the bent portion and is in compression contact with the inner periphery of the ink ribbon.
4 . The printer according to claim 3 , wherein
the support shaft includes a compression contact member that is in compression contact with the inner periphery of the ink ribbon, and
the attachment covers the support shaft from a side where the compression contact member of the support shaft is not present.
5 . The printer according to claim 1 , wherein
the support shaft includes a compression contact member that is in compression contact with the inner periphery of the ink ribbon, and
the attachment covers the support shaft from a side where the compression contact member is not present.
6 . The printer according to claim 5 , wherein
the attachment includes a compression contact member that is in compression contact with the inner periphery of the ink ribbon.
7 . A sheet support device, comprising:
a support shaft that is inserted into an inner periphery of a strip of sheet wound into a cylinder and supports the sheet; and
an attachment that is attachable/detachable to/from the support shaft, long in a longitudinal direction of the support shaft, and covers an outer periphery of the support shaft.
8 . The sheet support device according to claim 7 , wherein
the support shaft includes a compression contact member that is in compression contact with the inner periphery of the sheet, and
the attachment covers the support shaft from a side where the compression contact member is not present.
9 . The sheet support device according to claim 8 , wherein
the attachment includes a bent portion whose cross section orthogonal to the longitudinal direction is substantially U-shaped and a compression contact member that is provided on an outer periphery of the bent portion and is in compression contact with an inner periphery of an ink ribbon.
