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.
