Title: Scanner for photographic film
Inventor: MATSUMOTO FUMIO
IPC: G03B27/73
Filed: 1981-02-18
Abstract: PURPOSE:To scan the entire surface of a negative by color separation by a simple structure wherein a rotary disk having fitted filters, slit masks of various sizes, line sensor photodetectors, etc., corresponding to them are incorporated. CONSTITUTION:Light from a light source for lighting consisting of a lamp 8 and optical fibers 7 passes through one of filters 11 fitted to a rotary disk 10 rotated by a motor 9 to light up the screen 2 of a negative 1, and further passes through a scanning slit mask 3 to form a slit-shaped negative image 6 on an array of line sensor photodetectors 5 through a lens 4. The outputs of the line sensor photodetectors 5 are sampled every time the light passed through each filter 11 reaches the slit mask 3, and led out successively by a multiplexer, thus scanning the neagtive 1 at right angles to its advancing direction.

Title: Image reader
Inventor: TOYOMURA YUJI
IPC: B65H5/06
Filed: 1995-02-10
Abstract: PURPOSE: To prevent deterioration in read performance when an ADF is in use by using a brush roller and a brush energizing member to carry an original while being carried with the brush thereby eliminating the need for a glass window exclusively for the ADF. CONSTITUTION: An original 37 reaching a brush roller 34 of an automatic original feeder (ADF) unit enters a gap formed by rush energizing members 36a, 36b. Then the original overrides on a brush 35 implanted onto the brush roller 34 and is carried while being on the brush 35 and guided by the brush 35 under the original 37. Through the constitution above, the entire size of the image reader is made small by not providing a glass window for the ADF but extending the original glass 2a up to the image read position of the ADF. Furthermore, since the original 37 is carried while being in close contact with the original glass 2a, an image is read sharply. Moreover, the use of white brush 35 implanted on the brush roller 34 is preferred.
