Title: Image reader, image reading method, and image reading program
Inventor: OSHIMA TOSHIAKI
IPC: B65H85/00
Filed: 2001-07-31
Abstract: PROBLEM TO BE SOLVED: To provide an image reader, an image reading method, and an image reading program which shorten the manuscript read time by dispensing with the operation of inverting an image after read of a manuscript. SOLUTION: In a scanner 1 which can read both sides of the manuscript using an ADF 40, the shifting direction of a carriage 20 is reversed between the time of reading the manuscript before inversion and the time of reading the manuscript after inversion. That is, if reading both sides of the manuscript, the carriage 20 reciprocates once in the direction of sub scanning. Therefore, the period required for reading both sides of the manuscript is shortened. Moreover, when it reads the manuscript after inversion, the image data of the read manuscript are outputted with the disposition of pixel in the direction of main scanning arranged in reverse order. Therefore, the image based on the outputted image data is in the same direction as the image in having read the manuscript before inversion, and the operation of inverting the image after read of the manuscript becomes needless.

The memory controller 34 outputs auxiliary data for controlling the quantity of light of the laser light at the outside of the range corresponding to pixels in the scanning range of the laser light. A change-over switch 36 switches outputs of the line memory 32 and of the memory controller 34 on the basis of the change-over signal.  A light modulation part is provided for modulating the quantity of light of the scanned laser light on the basis of an output from the change-over switch 36.

Title: Belt for continuously variable transmission
Inventor: KANEHARA SHIGERU
IPC: F16G5/16
Filed: 2001-08-10
Abstract: PROBLEM TO BE SOLVED: To increase the durability of all metal elements by increasing the toughness of a stress-concentrated portion while assuring the wear resistance of metal elements. SOLUTION: In this belt for continuously variable transmission, a large number of metal elements 32 formed of a carbon tool steel are supported on a metal ring assembly 31.
