Abstract: A telephone conference system has a voice response board 6 for connecting a plurality of phone lines in a telephone conference, a voice synthesis board 8 for synthesizing voice signals for participants of a telephone conference in a designated one of a plurality of conference rooms, and a control section 18 for checking the status of a telephone conference and controlling connection of the phone lines for the conference. A host can input the phone numbers of intended participants of a telephone conference, and the system automatically calls the phone numbers of the intended participants and plays a recorded message to join the telephone conference within a scheduled time. When the participants call in to connect with the telephone conference, the caller ID numbers of their phone lines are compared to the recorded phone numbers to determine if they are true participants of the telephone conference.

Abstract: An emergency communication system connected to a plurality of user communication terminals through public lines comprises a receiver and transmitter section for receiving information from a plurality of user communication terminals and for transmitting information to a plurality of user communication terminals, an ID memory section for storing ID of each user, an ID confirmation section for confirming user ID by reference to ID data stored in the ID memory section when information is received from the each user communication terminal and permitting receipt of the information from the user in case that the received ID is compatible with the stored ID, an information accumulation section for accumulating information received from user in case that the ID confirmation section permits receipt, and an information addressee registration section for registering at least one addressees to which the information accumulated in said information accumulation section is communicated through public lines.

Abstract: Conventionally, an electrophotographic image forming apparatus by means of an electrophotographic image forming process has a process cartridge which integrates the electrophotographic photosensitive body and process means into a cartridge which can be detachably mounted on the image forming apparatus. In order to obtain a fine image in that kind of image forming apparatus, it is necessary that the process cartridge is mounted accurately at a predetermined position in the image forming apparatus and interface portions of various electrical contacts and driving transmission part are accurately connected. For improvement, process cartridges having well mountability are provided.

Abstract: An image forming apparatus has an interface portion for processing image information, a power supply device for supplying power to the interface portion, an opening/closing member capable of opening or closing relative to a main body of the apparatus, and a cover capable of opening the interface portion. In the image forming apparatus, the supply of the power from the power supply device to the interface portion is interrupted in an open state of the opening/closing member, and opening of the cover is prohibited in a close state of the opening/closing member.

Abstract: A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus which includes an openable closing member, a first main assembly guide movable in interrelation with opening and closing action of the closing member, and a second main assembly guide, the process cartridge include a photosensitive drum; a first cartridge frame portion extending in a cartridge mounting direction to the main assembly, at one axial end portion of the drum; a first cartridge guide projected from the first cartridge frame portion, the first cartridge guide moving the cartridge toward a cartridge mounting position by movement of the first main assembly guide with the cartridge being supported on first main assembly guide, upon mounting of the cartridge to the main assembly; a second cartridge frame portion extended in the mounting direction at the other axial end portion of the drum; a second cartridge guide projected from the second cartridge frame portion, the second cartridge guide movi

Abstract: A sheet-accommodating cassette includes a cassette body for accommodating sheets. The cassette body is made up of a main container and a sub container. Both the main container and the sub container have a plurality of engagement portions which enable them to be coupled to each other at one of a plurality of positions selected according to the size of the sheets to be accommodated. A sheet-accommodating cassette, which is formed by coupling the main container to the sub container in such a manner that the cassette can accommodate sheets of a large size, is housed in an image-forming apparatus body with part of the cassette protruding from the image-forming apparatus body.
