Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To improve the rotating performance of a tape reel and the running performance of a tape in a video tape cartridge furnished with a compression coil spring for pressurizing the reel and a reel retaining member. SOLUTION: A reel retaining base 12 provided inside the upper wall 11 of a main body case 1 is inclined downward to the rear surface of the main body case 1.

Inventor: ISHIDA YASUSHI
IPC: B65H3/06
Filed: 1995-10-17
Abstract: PROBLEM TO BE SOLVED: To provide a sheet feeder which can prevent a sheet from remaining in a device main body when a sheet loading means is pulled out of the device main body. SOLUTION: A cassette bucket is housed in a device main body 1 so as to be mountable and demountable.

Title: Method for generating real time tone reproduction curve to improve copied image
Inventor: FARRELL BARBARA L
IPC: G06T5/40
Filed: 1999-09-22
Abstract: PROBLEM TO BE SOLVED: To automate a generating process of sectional linear conversion of segments by scanning part of an image, deciding an input gray value to form the image and generating a histogram of frequency distribution of the input gray values. SOLUTION: A copied image or original is scanned to decide a gray value of image pixels and a histogram distribution denoting frequency of each gray value is generated. A background gray value from the histogram distribution is set as a maximum input order represented as a maximum reflectance Rmax of the histogram distribution. Furthermore, a minimum input border represented as a minimum reflectance Rmin is decided from the histogram distribution. After the input borders Rmax, Rmin are demarcated, segment points are decided in an area between both the borders. The segment points are obtained from identified characteristics of the histogram distribution such as peak, valley and offset values. Thus, the borders and segment points are automatically decided from histogram data being a base of sectional linear conversion.
