Title: Filter drive mechanism for image reading device
Inventor: SUZUKI MINORU
IPC: G03G15/04
Filed: 1990-11-20
Abstract: PURPOSE:To quickly and surely exchange filters and miniaturize a drive mechanism by moving the color filters from a retreat position to an insertion position by the oscillation of an oscillation arm, and returning them to the retreat position with a spring means. CONSTITUTION:A filter drive mechanism 31 includes color filters 33 of R, G, B, and M, four holding frames 35 retaining them, and four oscillating arms 37 corresponding to the frames 35. The engaging of a gear 553 of a drive gear 55 with a gear 571 of an output shaft of a stepping motor 57 and the rotation of the gear 55 by the actuation of a motor 57, causes the engaging of the gear 553 with a gear 377 of the arm 37 to oscillate the arm 37. This forwards the filters 33 to an insertion position I to be inserted in an image-formation optical path 41. The releasing of the engagement of the gears 553 and 377 causes the oscillation of the arm 37 to a retreat position Ro side with a coil spring 53 and the return of the filters 33 to the position Ro.
