ABSTRACT:
A scanning device includes sheet a holding member provided with an arcuate support surface open to the upside and one side for holding a sheet to be scanned on the back surface of which a magnetic layer is formed, a light source for irradiating the sheet to be scanned with light, a spinner including a deflection mirror for deflecting light from the light source toward the sheet to be scanned and a converging optical system for converging light deflected by the deflection mirror onto a surface of the sheet to be scanned, a motor for rotating the spinner coaxially with a center axis of the arcuate support surface, a light detector for detecting light from the sheet to be scanned, a sub-scanning motor for translating the sheet holding member relative to the spinner in parallel with the center axis, magnetic material provided on the arcuate support surface of the sheet holding member, sheet end portion holding members provided at one end portion of the arcuate support surface of the sheet holding member and adapted for abutting against one end portion of the sheet to be scanned to hold the one end portion at a predetermined position, and sheet pressing members provided at the other end portion of the arcuate support surface of the sheet holding member and adapted for abutting against the other end portion of the sheet to be scanned to press the sheet to be scanned along the arcuate support surface toward the sheet end portion holding members. According to the thus constituted scanning device, it is possible to hold a sheet to be scanned in close contact with a predetermined position of the arcuate support surface of a sheet holding means with a simple structure.
