  • Patent number: 9529318
    Abstract: An image forming apparatus includes an opening, an openable member, and a movable member for supporting cartridges in a state in which the cartridges are arranged in an arranging direction, movable in the arranging direction while passing through the opening between an inside position and an outside position in a direction crossing the arranging direction and a longitudinal direction. When the movable member is positioned at the inside position, adjacent two cartridges of the cartridges are in an overlapping state as seen in a direction perpendicular to the arranging direction and the longitudinal direction. When the movable member is moved from the inside position to the outside position and then one of the adjacent two cartridges is dismounted from the movable member, the one of the adjacent two cartridges is moved relative to the movable member so as to be prevented from interfering with the other cartridge.

  • Patent number: 6932699
    Abstract: A method and apparatus for a game that makes it possible to freely establish a region by expanding or contracting various regions relating to a game with a simple operation. If a closed region for expansion or contraction is moved to a position adjacent to an already established expansion or contraction object region, and an expansion operation performed in a state where a boundary of the closed region for expansion or contraction and a boundary of the object region, the closed region for expansion or contraction is added to the original object region to enlarge the area of the object region. Thus, the boundary displayed overlapping on the object region and the closed region for expansion or contraction are removed, and a single linked boundary is formed on the new object region.

  • Publication number: 20010031152
    Abstract: In a conventional color printer, especially an in-line type full color image forming apparatus, an aberration of optical axes caused by distortions of structures affect a performance of an image forming as a tilt aberration in a printed image. Accordingly, in a conventional color printer, distortions have to be prevented by strengthening rigidity of machine structures or parts of the machine. However, fine adjustment or assembling to strengthen rigidity generally causes an increase in cost and requires time-consuming adjustment. An apparatus in the present invention provides advantages of high accuracy and strengthened structure without increasing cost.

  • Patent number: 5967894
    Abstract: An image display game apparatus has a display screen which displays randomly selected five cards with their faces up. Based on the player's evaluation of the cards, the player selectively presses a first group of push buttons to select unwanted cards and indicate replacement of the cards. When the player presses a push button in a second group, the selected unwanted cards are replaced with new cards. If the new combination of the cards achieves a prize-winning hand, then the player wins and is awarded a credit based on odds for the prize-winning hand. The player then pushes another push button in the second group to receive medals corresponding to the credit. The image display game apparatus has an odds display device which displays a present prize-winning hand and odds thereof, a possible prize-winning hand and odds thereof, and other prize-winning hands and odds thereof in respective display modes, e.g., color shades, different from each other.
