摘要： PURPOSE:To make the photoelectric conversion output signal uniform by a method wherein the arrangement of a diode array is made coarse to dense from the center to the end. CONSTITUTION:The arrangement of light emitting diodes is so performed that the array end becomes in dense pitch, the center in coarse one, and the medium part in the intermediate one between dense and coarse, thus making the amount of image-forming light in an optical image forming plane uniform at a necessary part. As a result, the photoelectric conversion output signal becomes uniform because of obtaining the amount of uniform image forming light in said plane, therefore a uniform reproduced picture image can be obtained. Accordingly, the shading as conventional that the amount of image forming light by the uniform amount of light becomes large at the center of said plane and smaller toward the periphery can be corrected.

摘要： PURPOSE:To secure the receiving operation of a modem against a fault such as the momentary breaking of a circuit, by sending a training control signal to the modem if a received signal is interrupted momentarily, and then stopping training operation. CONSTITUTION:If a signal being received is interrupted momentarily, a carrier detection signal CDi is also interrupted immediately in response to that, but a carrier detection signal CD is stopped a prescribed delay time later. Consequently, the AND circuit in the training control signal generating circuit of a control part ANDs the inverted signal of the CDi obtained by an inverter 11 and the signal CD in said delay time to start a timer 10 with the AND output, and then the timer 10 generates a prescribed-time output. In this case, the control part when discriminating the momentary interruption as real one generates a training control indication signal TCE. Consequently, the output of the timer 10 is used as a training control signal TC as it is. A modem receiing the signal TC is inhibited from performing training operation during the reception.

摘要： PURPOSE:To perform a condensation of information, by dividing equally both the synchronous signal and the section of picture information, coding the presence or absence of the picture information in each block as well as the total number of the present or absent block of picture information and then transmitting the picture information of the block having the picture information. CONSTITUTION:The transmitted original 1 is read by a line by the reading part 2 and then supplied to the coding part 3. The part 3 codes the synchronous signal and the section of picture information that are divided equally and sends them to the modulating part 4. The modulated signal is transmitted to the transmission line 7 from the transmission network control unit 5. The part 4 gives a coding to the presence or absence of the picture information within a block to turn it into a control signal, and also gives a coding to the total number of the blocks having information or no information to turn it into a check signal. Thus a condensation is given to the facsimile signal and at the same time the detection is facilitated for the synchronous signal. In such a way, a detection is made possible for an error.

摘要： PURPOSE:To record a date, telephotography time and communication time on an original after transmission, by providing a facsimile equipment with a time clocking method and printing method. CONSTITUTION:When the terminal point of transmitted original 4 passes by original read point 12, form feed roller 11 and form discharge roller 14 are temporarily stopped by the command of signal processing part 6, which receives a confirmation signal for excellent reception at a reception at a reception side. At this time, the output signal of data generator 15 is printed out by printing mechanism 17 through print control circuit 16, thereby recording the date of transmission on original 4. Telephotography time recording is performed in the same way as the data recording with the exception that data generator 15 operates as a telephotography time counter. Count operation starts from read point 12 until the transmission end. As for communication time recording, the count operation starts when the communication circuit is connected to exchange 28 and ends at the point in time of a facsimile end. Then system mentioned above is extremely profitable in terms of the control of facsimile transmission and that of the use cost of the communication circuit.
