IPC: G03B27/46
Filed: 2002-09-24
Abstract: <P>PROBLEM TO BE SOLVED: To provide a film carrier excellent in operability and in light shielding property.  <P>SOLUTION: Image reading is performed by the film carrier provided with a masking mechanism set in an image reader. On this occasion, an upper guide 108 is opened in order to set a film F on a mask 106. As a result, a second light shielding member 114 on an upper surface of the upper guide 108 is attracted by a magnetic force to a lower surface 44A of a reading part casing 44. Moreover, an upper member 162 of the second light shielding member 114 is not separated from the lower surface 44A even when the upper guide 108 is blocked in order to fix the film F positioned on the mask 106, because the light shielding curtain 164 of the second light shielding member 114 is elastic. Accordingly, in the film carrier, light shielding is performed automatically by opening and closing operation of the upper guide 108 for setting the film F. Special operation for light shielding is not necessary and operability is improved, and simultaneously light shielding is completely achieved.  <P>COPYRIGHT: (C)2004,JPO
