Title: Color original reader
Inventor: FUKUSHIMA YOSHIO
IPC: H04N1/028
Filed: 1985-12-03
Abstract: PURPOSE:To stably reciprocate a filter without displacing it in the direction of optical axis by supporting a filter frame by a free end of two plate springs deflected within a plane in parallel with a filter plane. CONSTITUTION:A color separation filter 7 consists of a filter frame 8 fitted with 3 color R, G, B filters, two leaf springs 10 whose one end is fixed to a fixed member 9 and whose free end opposite to the fixed end is fitted to the upper and lower part of the filter frame respectively, a drive system 11 reciprocating the filter frame 8 vertically and a connecting member 12 connecting the filter frame 8 and the drive system 11. When the filter frame 8 is driven reciprocatedly vertically by the drive system 11, the leaf springs 10 are deflected, but the length of the two leaf springs 10 is equal and the spring constant is made equally, then the filter frame 8 is moved in parallel without being tilted. When the connecting member 12 is a link 12b having a pivot 12a at both ends, if the filter frame is deviated laterally, the pivot 12a is turned slightly and the link 12b is tilted to absorb the lateral deviation. Thus, the color information with fidelity to the original is read and the titled reader is made compact.
