Abstract

A support device, which supports a belt-shaped sheet wound around a hollow cylindrical shaft core so as to feed the belt-shaped sheet, includes a support shaft that is insertable into a hollow part of the shaft core, a frame that supports the support shaft, an antenna surface perpendicular to an axis line of the support shaft, and a loop antenna provided to the antenna surface. The shaft core includes a non-contact data carrier capable of at least one of storing and transmitting predetermined data. The loop antenna includes a loop unit coiled to define a loop surrounding the axis line. When the shaft core is seen through the loop antenna along the axis line, the loop unit is disposed in the vicinity of the shaft core.

Claims

1. A support device for a belt-shaped sheet that is configured to support a belt-shaped sheet wound around a shaft core having a hollow cylindrical shape in a manner capable of feeding the belt-shaped sheet, the support device comprising:

a support shaft configured to be inserted into a hollow part of the shaft core;

a frame that is configured to support the support shaft;

an antenna surface perpendicular to an axis line of the support shaft; and

a loop antenna provided on the antenna surface, wherein

the shaft core is provided with a non-contact data carrier capable of at least one of storing and transmitting predetermined data,

the loop antenna comprises a loop unit coiled to define a loop so as to surround the axis line, and

the loop unit of the loop antenna is disposed in the vicinity of the shaft core when the shaft core is seen through the loop antenna along the axis line.

2. The support device for a belt-shaped sheet according to claim 1, wherein

the shaft core has a first end portion provided at a first end and a second end portion provided at a second end in an axial direction of the shaft core,

the frame is provided near the first end portion, and

the antenna surface is provided near the second end portion.

3. The support device for a belt-shaped sheet according to claim 1, wherein

a profile of the shaft core overlaps a profile of the loop unit of the loop antenna when the shaft core is seen through the loop antenna along the axis line.

4. The support device for a belt-shaped sheet according to claim 1, wherein

the shaft core has a hollow cylindrical shape,

the loop unit has a circular shape, and

a diameter of a cylinder of the shaft core is the same as a diameter of the loop unit.

5. The support device for a belt-shaped sheet according to claim 1, wherein

the data carrier comprises a coiled antenna, and

a longitudinal direction of the coiled antenna extends along the axis line.

6. A method for managing a belt-shaped sheet that is supported by a supporting device in a manner capable of being fed, the supporting device comprising a support shaft configured to be inserted into a hollow part of a shaft core having a hollow cylindrical shape, a frame that is configured to support the support shaft, an antenna surface perpendicular to an axis line of the support shaft, and a loop antenna provided on the antenna surface and having a loop unit coiled to define a loop so as to surround the axis line, the method comprising:

winding the belt-shaped sheet around the shaft core;

providing the shaft core with a data carrier capable of at least one of storing and transmitting predetermined data;

disposing the loop unit of the loop antenna in the vicinity of the shaft core when the shaft core is seen through the loop antenna along the axis line; and

performing at least one of storing and transmitting of the predetermined data between the data carrier and the loop antenna.
