  • Patent number: 7582015
    Abstract: A game system includes: a direction mark storage section which stores image data of a direction mark which directs an operation of a player; a display control section which performs display control of a plurality of display objects including the direction mark; a timing acquisition section which acquires an operation timing; and an evaluation section which compares the acquired operation timing with a reference timing and evaluates the operation of the player. The display control section performs control of displaying the direction mark which directs the player to operate a plurality of operation regions by one mark. When the player operates the plurality of the operation regions of the operation section, the evaluation section evaluates the operation of the player by comparing the operation timing for the plurality of operation regions and the reference timing.

  • Patent number: 7574148
    Abstract: A light traveling permissible portion and a light traveling blocking portion are alternately disposed in a specification detecting and agitator driving gear such that a detection portion detects information corresponding to the maximum image formation sheet number. When the developer cartridge is new, a new/used cartridge detecting gear restricts transmission of the aforementioned information from the specification detecting and agitator driving gear to the detection portion for a predetermined time t, thereby detecting whether the developer cartridge is new or used. The detection portion detects whether the developer cartridge is mounted based on whether the detection light reflects from the light traveling permissible portion.

  • Patent number: 7555238
    Abstract: In an image-forming device, a belt unit is detachably mounted in the housing. The belt unit moves to an installation position along a linear insertion/removal path in an insertion direction when the belt unit is mounted in the housing. The belt unit includes: a plurality of rollers; and an endless belt that is supported by the plurality of rollers and is capable of moving circumferentially around the plurality of rollers. A surface of the endless belt contacts a surface of the at least one photosensitive member when the belt unit is located in the installation position. The endless belt moves in a belt-moving direction that is angularly shifted from the removal direction to allow the surface of the endless belt to separate from each photosensitive member when the belt unit starts moving in the removal direction from the installation position.

  • Publication number: 20090152791
    Abstract: A first guide member includes a concave-shaped guide surface. A recording medium such as a sheet fed by register rollers takes a curved position while being fed in a sheet feeding direction such that the leading edge of the sheet slides on the guide surface. A space is defined between the sheet and the guide surface due to the stiffness of the sheet. Thus, the sheet smoothly curves. When a speed of conveying the sheet by the register rollers is faster than a speed of conveying the sheet by a conveying belt, slack in the sheet is allowed in the space defined between the sheet and the guide surface. Therefore, the sheet can be stably conveyed without applying excessive load to the sheet or a sheet conveying device.

  • Patent number: 7537425
    Abstract: The wafer processing apparatus includes a chamber that is pressurized to a pressure that is higher than the pressure of the exterior thereof, an opening portion through which the interior and the exterior of the chamber are in communication with each other, and a door that closes the opening portion. When the opening portion is closed by the door, a portion of the opening remains as an aperture uncovered by the door. In conventional semiconductor wafer processing apparatus, the interior of the apparatus is sealed and pressurized in order to keep a high degree of cleanness in the wafer processing portion, and therefore airflow is generated due to a pressure difference between the interior and the exterior of the apparatus. With the above feature of the invention, it is possible to suppress creation of such airflow and prevent dust from entering the wafer processing apparatus to eliminate wafer contamination.

  • Patent number: 7496317
    Abstract: A feeding unit is disposed near the lower edge of an access opening formed in a front cover of a main casing. The feeding unit includes a pair of registration rollers and a pair of guide parts. One of the registration rollers and one of the guide parts are retained on the front cover. Thus, when the front cover is pulled to an open position, the registration roller and the guide part retained on the front cover displace together with the front cover, exposing a paper conveying path.

  • Patent number: 7493062
    Abstract: An image-forming device includes: a main device body; a plurality of process cartridges; a fixing unit; a tray; a switchback conveying path; and a reverse conveying unit. The plurality of process cartridges are detachably mounted in the main device body. The process cartridges are arranged in a row in the main device body when the process cartridges are mounted in the main device body. Each process cartridge has an image-carrying member that transfers a developer image carried thereon to a sheet by opposing the sheet. The fixing unit is provided in the main device body and fixes the developer image to the sheet after the image has been transferred thereto. The tray is provided in the main device body and supports the sheet after the developer image has been fixed thereon. The switchback conveying path is provided in the main device body and guides the sheet from the fixing unit to the tray, while switching a conveying direction of the sheet.

  • Patent number: 7479064
    Abstract: An operating apparatus for game machine includes a depressing member, and a main body of the depressing member is provided with three engaging protrusions and two depressing protrusions that downwardly protrude. For example, the two depressing protrusions are provided between the three engaging protrusions. In response to a beating operation by a player, the right side of the depressing member is depressed, and then, an engaging portion of the engaging protrusion at the left side is engaged with a rear surface of an upper surface panel. Accordingly, the depressing member is sure to be depressed at the right side without being upwardly actuated, and a rubber switch depressed by the depressing protrusion is brought into contact with a board. At this time, a contact provided on the board and a contact provided on the rubber switch are brought into contact with each other, and an operation signal according to the beating operation is output to the game machine.

  • Patent number: 7457553
    Abstract: A blocking disk formed with a notched part is disposed between a density sensor and a belt. The exposure/blocking of the density sensor relative to the belt is switched by rotating the blocking disk. In one example, a disk-supporting axel gear is formed on a disk-supporting axel that is the axis of rotation of the blocking disk, where the disk-driving gear is supported on a sensor frame so as to be able to rotate and so as to mesh with this disk-supporting axel gear. In one example, the disk-driving gear is connected to a driving force transmission mechanism for rotationally driving a belt-driving roller, where, when the belt-driving roller is driven rotationally, the blocking disk is constantly rotated by a disk-driving gear.

  • Patent number: 7454158
    Abstract: A laser printer is detachably provided with a carrier belt, support rollers for supporting the carrier belt, and a belt unit provided with a belt frame. A unit support portion for supporting a bearing portion of the support roller and a unit support portion for supporting a bearing portion of the support roller are provided at a side of the main body of the apparatus. Urging by a coil spring allows the bearing portion to press the unit support portion against the support roller. An image forming unit that contains four process cartridges is detachably provided above the belt unit opposite to the belt. The belt unit may be removed from the main body by detaching the image forming unit.
