An optical transceiver performing the full-duplex transmission in a plural channel is disclosed. The optical transceiver provides an optical receptacle, a semiconductor optical device, an inner fiber that optically couples the optical receptacle with the semiconductor optical device, and a fiber tray that secures an extra length of the inner fiber. The fiber tray provides an inner wall inclined toward a direction perpendicular to a direction along which the inner fiber warps. The inner fiber is set within the space as touching the inclined inner wall and sliding thereon toward the inclined direction.

An optical transceiver easily set within the cage of the host system. The optical transceiver of an embodiment provides a finger surrounding the housing of the optical transceiver. The finger has an rear edge, whose tip is bent downward so as to be received in the first groove of the housing, extending diagonally to the brim of the cage; and a reinforced portion with a U-shaped cross section tightly set within the second groove of the housing.

A facsimile receiving processing unit in a facsimile server terminal receives and stores facsimile data in a data storage unit. A receiving-end user issues a request for accessing the received facsimile data stored in the data storage unit through a received facsimile accessing unit in a client terminal to a received facsimile manager in the facsimile server terminal. At the time when the received facsimile data is accessed for the first time, a response data creating unit in the facsimile server terminal automatically creates response data which indicates that the facsimile data has been accessed at the receiving end, and then the response data is sent back to the sending-end facsimile machine by a facsimile transmission processing unit in the facsimile server terminal. This allows the sending-end user to recognize whether the facsimile data has actually been accessed by the receiving-end user.

A facsimile apparatus has a transparent plate on which a document may be located. The document is then scanned by a scanner which includes electronic solid state light generation means e.g. LEDs which illuminate the document, with the light reflected from the document being detected by a detector. An electronic signal corresponding to an image of the document may then be transmitted to a remote location. Alternately, the facsimile apparatus may be used to copy the document. Cut paper sheets are withdrawn from storage and an image printed thereon by a heat transfer system in which a film of ink is selectively heated. Paper on which an image has been printed is then received on the upper surface of the storage. The facsimile apparatus may also have a document transporter for moving a document past the scanner with the scanner fixed.
