Publication number: 20020194085Abstract: A store apparatus determines the number of points given to a customer who has purchased a commodity using a customer apparatus via the Internet, in which the number of points are determined based on a roulette game. Since the point value given to the customer who purchases the commodity is determined by the roulette game regardless of the cost of the commodity purchased, the specific time period when purchased or the specific commodity purchased, it is possible to keep the willingness of the customer to purchase commodities and to direct that willingness to all commodities. In addition, since the customer can acquire higher points than the points usually given depending on the result of the roulette game, it is possible to further rouse the willingness of the customer to purchase commodities. Further, the customer is capable of shopping with more fun.Type: ApplicationFiled: June 6, 2002Publication date: December 19, 2002Applicant: Sony Computer Entertainment Inc.Inventors: Hitoshi Kageyama, Toru Kuwahara, Koji Kishi, Tetsuya Iida

Patent number: 5561743Abstract: A copying machine for forming an image by scanning a laser beam which is emitted from an optical system on a photosensitive member. Photosensors are provided at optically equivalent positions to a beginning portion and an end portion of a scanning line on a photosensitive member. A scanning time of a laser beam in the main scanning direction is measured by these photosensors. The measured time and a standard time for a copy magnification set by an operator are compared, and a correction value is calculated, and at the same time, magnification in the main scanning direction is corrected using the correcting value. Also, focusing (adjusting of the beam diameter) is carried out using the photosensors. Each of the photosensors contains a photoelectric transfer element, and a beam which comes through a slit is incident to the element. Each photosensor is provided with two slits. One is perpendicular to the main scanning direction, and the other is inclined to the main scanning direction.Type: GrantFiled: June 7, 1995Date of Patent: October 1, 1996Assignee: Minolta Camera Kabushiki KaishaInventors: Nobuo Kanai, Hitoshi Kageyama, Kenji Takeshita

A desired color in an original image is designated by a designated color input portion and thereby designated color data for separated colors are obtained. Thereafter, the original image is scanned and image data for separated colors are obtained. The thus input image data are electrically edited in the selected edit mode based on the designated color data and the edited image data are output to an image forming unit and thereby an edited color image is obtained.Type: GrantFiled: May 21, 1992Date of Patent: August 2, 1994Assignee: Minolta Camera Kabushiki KaishaInventors: Hitoshi Kageyama, Osamu Yamada, Shinichi Mori
