Abstract: PURPOSE:To quickly decide a communication method and to perform smooth and quick communication by adding the transmission function of plural tones and a function for detecting signals coming from a transmission side while the plural tones are transmitted to a reception side. CONSTITUTION:First, when an incoming call from a telephone circuit is present, a relay 2 is energized, a MODEM 3 is closedly connected to the telephone circuit 1 and the plural tones including CED signals are transmitted. Then, when a command from an opposite party is confirmed while the plural tones are transmitted, mutual communication is immediately started. When no command signal from the opposite party is present, after the plural tones are continuously transmitted until time-out, initial identification signals are transmitted and transmission is repeated with a fixed interval until the command arrives from the opposite party. Then, the transmission side connects the MODEM to the telephone circuit, performs automatic dialling and then, waits for a response from the reception side while transmitting CNG signals. During the time, the tone other than the CED is received, the transmission of the CNG signals is stopped when it is one of the object plural tones and the command signals are transmitted. Also, when the object plural tones are not received, the initial identification signal is waited for when the CED signals are received and the command is transmitted when the initial identification signal is present even when no CED signal is present.

Abstract: PURPOSE:To attain the automatic evolution and output of the document data in the form of a specified layout and according to a layout rule corresponding to the logic structure, by obtaining the logic structures of the chapters, paragraphs, itemization, the ends of paragraphs, etc., from the data of inputted sentences. CONSTITUTION:The document data supplied from an input part is stored in an original memory part 3 via a document control part 1. At the same time, a segmenting code, e.g., a renewing row code is detected out of the document data and a group of sentences which are segmented by the segmenting codes are successively extracted. Here the length of a single sentence is also measured. A header extracting part 6 decides whether or not an extracted sentence is possibly used as a header based on the length information of the single sentence and with reference to a headword dictionary 6a. Thus a header candidate is obtained if said sentence complies with a standard. This header candidate is compared with the header rule stored in a header rule dictionary 7a through a header deciding part 7. Then a header sentence is decided if the header candidate is coincident with the header rule. While a document text, like the end of a paragraph, etc., is decided if no header sentence is confirmed.

Abstract: PURPOSE:To obtain an optical scanner which has a semi-permanent life, is small in size and low in cost by bending both sides of a mirror mounting part of a leaf spring to directions opposite from each other so that both ends of the leaf spring are approximately paralleled and increasing and decreasing the distance between both ends of the leaf spring by an expanding and contracting mechanism thereby rotationally driving a mirror. CONSTITUTION:The mirror 2 for scanning light is mounted to approximately the central part of the leaf spring 1 and both sides of the mirror mounting part of the leaf spring 1 are bent in the directions opposite from each other so that both ends of the leaf spring are approximately paralleled. The expanding and contracting mechanism 3 to increase or decrease the distance between the two ends of the leaf spring 1 is provided so as to generate the motion in the rotating direction in the mirror 2. The leaf spring 1 is deformed and the mirror 2 rotates when compressive force is exerted to both ends of the buckled leaf spring 1 in the direction shown by arrows. The need for providing a sliding part is thereby eliminated and the life is semipermanent since there are no wearing parts. In addition; the scanner is reduced in size and is produced at the lower cost.
