A light therapy appliance comprises an electronic circuit including Light Emitting Diodes configured to emit light at one or more different wavelengths. In each processing cycle, a control unit executes control processing to pieces of instruction information in a predetermined sequence and outputs, as connection information, an assignment of the components thereof obtained in the control processing. Accordingly a transponder support provided with the transponder is able to be reused, after its intended first use, in a new plastic support. The deblur engine then deblurs each image segment based on the coherent motion of each different image segment and combines the resultant, deblurred image segments into a deblurred image. The controller includes circuits to detect the presence of predetermined faults and to emit an audible fault indicator in response thereto. A nut member is mounted on the outer periphery of the spool shaft, such that the retaining member is interposed and fixedly held between the annular member and the nut member.
