Abstract: PROBLEM TO BE SOLVED: To omit a pre-scan operation that must insert to twice an original into the carrier part of a printer by designating a prescribed range within the original and reading only the image of the designated range when the original size or a sheet type serial color reader is already known. SOLUTION: When a reading range no is designated within an original 9 of a regular size, the position of the range 90 is measured by a user. Based on this measured position, a host computer designates the moving direction of a carriage and the reading direction together with the starting positions S1 S2 and reading length L1 and L2 of both directions respectively. If the original size is not fixed and also it's desired to read a limited range of this original, a reading range is designated by a pre-scan function. In this case, only an LED of G (green) is turned on among three colors R (red), G and B (blue). In other words, the reading time can be shortened down to about 1/3 when a pre-scan is carried out with reduction of moving frequency of the carriage.

Abstract: PURPOSE:To obtain a read picture excellent at all times by applying subscanning to an original at a prescribed speed when a width of a visual field of a cell of a line sensor is a half of one line pitch in the subscanning or below. CONSTITUTION:When the line density is set to the usual character mode, a subscanning control section 4 applies subscanning to an original intermittently by each of one-line pitch 65mum based on a stepwise moving characteristic for a prescribed period T3. In this case, after movement of one-line pitch, the movement of the original is almost at a standstill for a prescribed period T4. Then a control section 5 extracts a picture signal one by one line each from a CCD line sensor 1 for a prescribed period T3. When the width of the visual field of the cell of the line sensor is a half of one line pitch in the subscanning or below, the one-line pitch block of an original picture is uniformly read by applying subscanning to the original at a prescribed speed. Thus, the picture quality of the read picture is improved.

Filed: 1987-05-21
Abstract: PURPOSE:To prepare an accurate fluorescent screen pattern by allowing a linear light source to perform an elliptical motion with longer dia. in the direction perpendicular to the longitudinal direction. CONSTITUTION:When a drive motor 16 is started to rotate a crank arm 25 through a reduction gear 17 and output shaft 17a, an actuator 25 of an arm 25 moves while sliding on an elliptical ring-shaped groove of a drive plate 23. Thereby a linear light source 5 of an exposure device 4 makes elliptical motion while drawing the same elliptic locus as the elliptic shape of the elliptical ring-shaped groove without rotation and performs a specified exposing action to a photo-sensitive film 12 of a face panel 11. By this exposing action the exposures to the photo-sensitive film 12 will be overlapped concentrically wherein the elliptical exposure by the light source 5 itself and that by elliptical motion of the same are intersecting in right angle to each other. As a result correction is made into exposure with nearly genuine circle, and thus accurate fluorescent pattern is prepared.
