摘要： An optical distributor includes an optical-signal input port, a light receiving device, a light emitting device, a light splitter, and optical signal output ports. The light receiving device converts an optical light signal input to the optical-signal input port into an electric signal. The light emitting device converts the electric signal into an optical signal. The optical splitter 14 splits the converted optical signal into two optical signals. The optical-signal output ports output the split optical signals. The light receiving device includes a light receiving element, a pre-amplifier, and a limiting amplifier. The light emitting device includes a light-source drive element and a light emitting element.

摘要： An image reading device of the type in which a display panel is laid over a document table and an image on an original document is input through the display panel. In the image reading device, the display panel is a liquid crystal panel of the transmission type in which liquid crystal/polymer composite material is sandwiched by electrodes, and at least one of the electrodes sandwiching the liquid crystal/polymer composite material consists of a plurality of divided electrodes. Further, a gap between the adjacent divided electrodes is shorter than a minimum resolution distance in a location of the display panel of the image reading device. Alternatively, an electrode layer may be provided covering the gap between the adjacent divided electrodes in a state that an insulating layer is layered between the electrode layer and the gap. The ends of the divided electrodes may overlap with each other, with an insulating layer being layered therebetween. In this case, no gap is present between the adjacent divided electrodes. A distance t between the display panel and the document table is preferably 3 mm.ltoreq.t.ltoreq.30 mm.

摘要： Deletion of a particular message in a file unit is accomplished for those messages with deletion set code in a file directory displayed on a screen. Operation of the deletion of a message includes (a) depression of a "deletion" key for indicating a file directory on a screen, (b) designating messages to be deleted by depression of a deletion set/reset key to change a deletion set/reset code to a set code, and (c) execution of deletion by the depression of a "deletion execution" key to delete a message with said deletion set code. A file directory indicated on a screen includes a deletion set/reset code, a message number, nature of a message, length of a message, and first 60 characters of a message, which simplifies identification of a message to be deleted.
