Title: Image reader
Inventor: IKEDA YASUHIKO
IPC: H04N1/04
Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To reduce the size and cost of an image reader by reading an image with low resolution when it's pre-scanned and saving an original to a saving path when it's carried in the negative direction. SOLUTION: A fed original 4 is carried to an original reading part 11 after passing between an original scooping sheet 22 and a lower original guide 13. Then the image of the original 4 is read at the part 11 in a read (pre-scan) mode where the image is roughly read and the image outline is grasped. A user designates an image read range and sets the density and resolution based on the image shown on the screen of a PC(personal computer) 14. Thus, every roll motor revolves reversely. Then the rear end part of the original 4 is scooped by the sheet 22 and carried to an original saving path 20 that is separated from other originals 4 set on an original board 3a.

Title: Fertilizing and sowing apparatus
Inventor: NAKAMURA SHOICHI
IPC: A01C15/00
Filed: 1988-06-21
Abstract: PURPOSE:To surely release granular material in high efficiency by setting the circumferential rotational speed of a furrowing rotor to be larger than the running speed of the apparatus and providing a pushing tool to push out the granular material. CONSTITUTION:Granular material delivered from a fertilizer-storage hopper 7 is received by a receiving part 23a. The receiving part 23a contains a pushing tool 27 for pushing out the granular material. The granular material is forcedly released with the pushing tool 27 by the rotation of the furrowing rotor 22. Since the rotational speed of the furrowing rotor 22 is larger than the running speed of the apparatus, the furrowing rotor 22 can be driven while cutting mud soil by protruding a side plate 24 of the furrowing rotor 22 beyond a circular cover 30. Accordingly, the mud-pushing action can be decreased to prevent the falling of the already transplanted seedling. The granular material pushed out with the pushing tool 27 is scraped off with the mud moving relative to the granular material. There is no adhesion of soil to the pushing tool 27.
