A support device, which supports a belt-shaped sheet wound around a hollow cylindrical shaft core (24) so as to feed the belt-shaped sheet, includes a support shaft (221) that is insertable into a hollow part of the shaft core (24), a frame that supports the support shaft (221), an antenna surface (273) perpendicular to an axis line (C) of the support shaft (221), and a loop antenna (274) provided to the antenna surface (273). The shaft core (24) includes a non-contact data carrier (26) capable of at least one of storing and transmitting predetermined data. The loop antenna (274) includes a loop unit (274a) coiled to define a loop surrounding the axis line (C). When the shaft core (24) is seen through the loop antenna (274) along the axis line (C), the loop unit (274a) is disposed in the vicinity of the shaft core (24). |
