Title: Image reader
Inventor: KUWAMOTO SHIGEKI
IPC: H04N1/04
Filed: 1996-02-06
Abstract: PROBLEM TO BE SOLVED: To easily read an image by a size suitable for screen resolution in a display, to set a fixing point in the positional coordinate desired by a user at the time of changing a reading range and also to definitely set the reading range in the display with a different range measure. SOLUTION: When the reading range of 100dpi in resolution, 600×400 dot fixing in dot numbers and 6×4 inches in length is set, a point P(Xp, Yp) in a figure is the optional logical coordinate when the upper left angle of the whole range is adopted as an original point. Since the reading range is the pattern of a mountain and the moon in the figure, the user changes resolution to be 200dpi being one-fifth. By the resolution change, the dot numbers of the reading range is fixed and resolution is linked so that length is changed to be the five-fold one, that is, 30×20 inches with the P point as the fixing point and the reading range is changed.

Filed: 1982-03-19
Abstract: PURPOSE:To obtain a compact zoom lens which has short overall length and excellently compensated aberrations, by allowing the lens system consisting of a negative, a positive, a positive, and a negative lens group from an object side to meet specific requirements. CONSTITUTION:In the zoom lens system consisting of the negative lens groupI, positive lens group II, positive lens group III, and negative lens group IV successively from the object side, the 1st-the 3rd groups are moved independently of one another for zooming. The 1st groupIand the 2nd group II are put closest at a telephoto side zooming position and thus its rear open aperture is reduced to make the constitution compact, compensating the aberrations at the telephoto side. The 3rd group III and the 4th group IV are put closest at a wide angle side zooming position to obtain a sufficient back focus. The focal lengths of the 1st groupIand the 4th group IV are made less and greater than the focal length of the zoom lens system to suppress aberrations from the front group. Consequently, the compact zoom lens having the aberrations compensated excellently is obtained.
