The sheet separation apparatus for separating a transfer sheet from a toner image bearing photoconductor for use in an electrophotographic copying machine comprises a plurality of separators which are rotatably mounted on a shaft arranged parallel to the photoconductor, and each of the separators is independently urged into pressure contact with the surface of the photoconductor by a spring member through a control member which is substantially integral with the shaft. In one embodiment of the sheet separation apparatus, the control member serves as a protector for preventing toner particles from being scattered from the surface of the photoconductor and in another embodiment of the sheet separation apparatus, the shaft can be turned about a predetermined point of one end portion of the shaft in the direction that the other end portion of the shaft can be moved away from the photoconductor for easy maintenance of the sheet separation apparatus.

A browsing data creation system of an information searching apparatus includes a data storage for storing plural kinds of data that are to be searched for. Each of the data having a data format corresponding to the kind of data that it is. Instructions can be input into the information searching apparatus and browsing data can be created from the data stored in the data storage according to a data format input into the information searching apparatus. Data that is to be searched for has a time based access and is divided into page units. An instruction is input to the information searching apparatus to search in page units.

A communication network system comprising a communication line network, a plurality of terminals connected to the communication line network, and a fuzzy control unit for allocating a right to access the communication network according to a fuzzy deduction process taking into account an operating condition of the system. This communication network system may consist of a local area network involving a polling process or a token passing process, a computer terminals systems, or a telephone exchange system. By using a fuzzy control process, an efficient utilization of available resources is made possible by taking into account operating conditions of the network as a whole, or each of the terminals.

A variable focus objective lens having a magnification range in the order of 1 : 30 and greater and having two pairs of relatively movable members which objective consists of a front assembly and a rear assembly which includes one of the two pairs of movable members to which consecutive zooming movement is imparted. This is done in order to add a varifocal range to a varifocal range of zooming movement of the movable members of the front assembly, in association with a control mechanism of simple structure incorporated in barrels of the lens mount therefor.

A tape cassette having a head-receiving housing region provided with an independent guide block which contains a plurality of tape guides, further comprises a pair of thick spacer plate members disposed, respectively, between the guide block and the upper and lower half housing sections of the cassette. The spacer plate members are made of a material suitably chosen from among metals, metal-plastics composites, carbon fibers, glass fibers, composite reinforced plastics containing mica or other reinforcements, and the like. They have a plurality of irregularly shaped apertures or positioning apertures each which receive posts formed in one piece with the upper and lower half housing sections of the cassette and are fixed in position with the posts by caulking. The guide block has portions with which to press the thick spacer plate members securely against the respective half housing sections of the cassette.

A disc cartridge and a casing therefore capable of carrying out insertion and removal of a disc with respect to the casing without separating a shutter from the disc cartridge and adversely affecting the disc, with simple operation. The casing includes a casing body constituted by an upper cover member and a lower cover member joined together to form an inner space therein which is adapted to rotatably receive therein a disc having a non-recording section formed at its outer periphery and be separable at rear ends thereof from each other. The casing also includes a pair of guides arranged on both side of a rear portion of an interior of the casing body so as to be opposite to each other. The guides permit insertion and removal of the disc with respect to the casing body to be safely accomplished along the guides through the opened rear end of the casing. The disc cartridge uses such a casing.

Browsing data in the format selected by a user can be created by using the existing art. Video and audio can be browsed by designating only the portion to be browsed. A system for creating a compound document is used so as to create browsing data from application data. When audio data and videa data are played, a concept of a virtual page is introduced so that they can be browsed in page units.
摘要:
A magnetic tape cassette has in the front portion of the housing two pairs of fixed tape guide ribs protruding the same length frontwardly of the housing to define a guide path for the magnetic tape and also protruding so as to form linear front edges of a height greater than the width of the tape, the fixed tape guide ribs in at least one pair being formed adjacent to each other, with the upper and lower ends of the protruding front edges being integrally joined by bridges of the same material. The bridges are formed to have a given, constant width and a given, constant height upwardly and downwardly.

A disc cartridge capable of readily accomplishing centering of a disc. The disc cartridge includes a casing which has a front end through which the disc cartridge is inserted into a disc player and a rear end which is opposite to the front end. At least the rear end is provided on an inner end surface thereof with an elastic means which acts to force the disc toward the front end to correctly position the disc in the casing when the disc cartridge is charged in a disc player.
