Abstract: A fuser includes a fusing roll unit having a fusing roll, a pressurizing roll unit having a pressurizing roll and a coil spring resiliently biasing the pressurizing roll. The units are secured by a pair of engagements. One engagement includes a hook provided at the fusing roll unit and an eye provided at the pressurizing roll unit and capable of guiding and thus moving the units pivotably relative to each other when said hook is engaged therein. The fuser can thus have a simple structure formed of a reduced number of components and enhancing workability and facilitating its fabrication.

Abstract: A game apparatus and a method of replaying a game display a moving entity which moves in a given area on a display screen. The game apparatus has a memory for storing, for a predetermined period of time, absolute coordinates in the predetermined area of a moving entity which moves in the predetermined area in response to a control signal entered by an operator while a game is in progress, and a display data generating unit or reading the absolute coordinates from the memory in response to a replay request from the operator and processing the absolute coordinates into display data depending on processing information supplied from an input unit by the operator.

Abstract: An image processing apparatus capable of displaying guidance and of setting the operating environment for an application program when the capability of a computer system is different from the operating environment expected by the application program. The image processing apparatus comprises: a CD-ROM drive 8 for loading an application program; a main processing unit 2 for forming graphic signals by executing the application program; and a display 3 for displaying the graphic signals. The main processing unit comprises: a determining unit 211 for determining whether or not the main processing unit 2 has provided the operating environment expected by the application program; a display control unit 212 for displaying guidance on the display 3 based on the results of the determination of the determining unit 211; and a setting unit 213 for allowing the operating environment of the application program to be set by the main processing unit 2.

Abstract: A data reading and image processing system for a video entertainment system with a CD-ROM capability is disclosed with a pair of separate computer systems that are controlled through a controller for accessing data from a memory unit. A first computer system can control the reading of data and the storing of the data in the memory unit in coordination with a first synchronization time period while the second computer system can control the processing of video data signals in an image processing circuit during a second synchronization time period. The data can be appropriately enabled to a position within the memory unit to assist in parallel processing by both computer systems.

Abstract: A program operating apparatus comprises a body unit and a memory unit, attachable to and detachable from the body unit, for storing an application program. The memory unit stores sales area data indicating sales areas of the memory unit. The body unit stores sales area data indicating sales areas of the body unit. When executing software of the memory unit, there are checked the sales area data of this memory unit and the sales area data of the body unit. Thus, the memory unit sold in areas exclusive of the sales areas of the body unit is prevented from operating on that body unit. Similarly, the body unit sold in areas exclusive of the sales areas of the memory unit prevents an execution of the memory unit.

Abstract: A data security apparatus and method permits programmed data stored in a replaceable external storage medium to be processed by the data processor when it is determined that a security code is stored on the external storage medium and a replacement second external storage medium is available. The data can then be transferred under a controlled process without performing a security check on the second external storage medium. A hardware security apparatus can therefore be disabled to permit authorized game developers to test their games on an actual game system.
