Abstract: PURPOSE:To prevent ink from coming off an ink sheet by transporting the ink sheet and a recording medium at the same speed and in the same direction during the discharge or insertion of the recording medium, when both the recording medium and the ink sheet are transported in the same direction for recording using the recording medium. CONSTITUTION:Recording paper 11 is inserted inbetween a thermal head 13 and a platen roller 12 by the rotation of the latter 12, and the recording paper 11 is transported to a discharge roller 16 at a speed Vp. At that time, an ink sheet transport motor 25 and an ink sheet winding motor 38 are driven simultaneously to transport an ink sheet 14 at a speed V1. In this case, the recording sheet 11 and the ink sheet 14 are transported in close contact with each other, and the speeds Vp and V1 are almost equal with each other. Image data of a single line is transferred to the thermal head 13 to record an image. If the image recording of a single page is completed, the ink sheet 14 is transported at the same speed as the recording paper 11 by the rotations of the motors 25, 38 during the discharge of the recording paper 11, as long as the roller 12 rotates. Thus it is possible to prevent ink from coming off the ink sheet and prevent the deformation of the ink sheet.

Abstract: PURPOSE:To automatically start communication by providing a means selecting automatically a data communication mode in responses to the presence of the dialing operation depending on the state of a prescribed member of data communication and on a prescribed dialing means. CONSTITUTION:An operator uses a ten-key or one-touch key 31 of a telephone set to apply voice communication or facsimile communication. In this case, a dial signal (pulse or DTMF) in response to the mode setting is outputted. In this case, a dialer 30 outputs PMUT, TMUTE signals being control signals to a speech network and the TMUTE signal goes to a low level synchronously with the dialing signal, then it is detected by a CPU 1 via a photocoupler. The CPU 1 detects the dialing and when an original to be sent is loaded to a read section 7, a CML relay 22 is turned to the position of the facsimile equipment.

Abstract: PURPOSE:To prevent a void between lines at the time of receiving data without adding a special hardware by recording the same data in the same position twice at the time of receiving the data having low subscanning density in a thermal recording system of a facsimile equipment. CONSTITUTION:At the time of starting to receive a G2 picture one byte of the decoded data from a modem 14 is received and written in a line buffer 1 for picture data on a memory 15. Next, when the following line begins to be received and pulse is outputted from a pulse generator 7 which is at 10 msec interval, an interruption occurs in a CPU. The picture data begins to be transferred and the picture data transferred in a record head is recorded in a 10 msec by the control of a slave CPU. A main CPU executes the increment of a COUNT and 10 msec after the process of interruption is completed, the interruption occurs again. And one line of record is made to start and the same data is made to be recorded in the same position of the recording paper twice.

Abstract: PURPOSE:To perform connection to an opposite bypassing a circuit by a forward-transfer means when a circuit traffic is busy, and to utilize a transmission line with superior transmission picture quality, by performing a forward- transfer requesting a short connection when the connection to the opposite is not detected by a supervisory means in clocking by a timepiece means. CONSTITUTION:A control unit 100 in a data communication equipment starts up a trunk line start up circuit 200, and calls trunk lines L1 and L2 by forming a DC loop on the trunk lines L1 and L2. Also, at the time of detecting a dial signal from a station side, an automatic dialing set 300 is started up, and the FM signal of a telephone number corresponding to a call opposite, is sent to the trunk lines L1 and L2. Afterwards, a line supervisory means 400 supervises the completion of the sending of the FM signal, and a timepiece means 500 is started up, then a start signal is outputted. The inversion of the polarity in the signal of a telephone set responding previously is supervised, and the clocking by the means 500 is stopped by the inversion of the polarity. And the control device 100 performs the connection to the opposite bypassing the circuit when the traffic is busy.

Abstract: PURPOSE:To attain the easiness of confirmation and transmission for all picture informations at the reception side by adding a prescribed picture information expressing a final original to the picture information of the final original at the detection of a final page original so as to send the result. CONSTITUTION:When the original is lost in a loading position, a control section 11 reads a graphic pattern such as a character or symbol representing the final original, adds it to the end of picture information of the final original and sends the result. Thus, the character and symbol representing the final original are recorded at the final end of the recording paper reproduced at the reception side and it is confirmed that all the information to be received is recorded by visual recognition and the job classifying plural communications of recording paper is facilitate. The confirmation of communicating operation is facilitated by combining this system with the system sending automatically the image such as the page number of a sender.

Abstract: PURPOSE:To attain conversation regardless of communication modes, by providing a means which detects that a transmitting side wants to make ordinary conversation when receiving side facsimile equipment is set to an automatic reception mode. CONSTITUTION:When facsimile equipment receives a call signal from a telephone circuit (W) under a condition where the equipment is set to an automatic reception mode, a main power supply device 27 is actuated and a CPU 2 starts control. Then the circuit is switched from the telephone set to the facsimile and a called station discriminating signal is sent from a MODEM 14 to the circuit (W). Thereafter, sending of G2 discriminating signal and detecting operation of the G2 instruction signal of the calling side are repeated. While the G2 instruction signal is detected, a loudspeaker 19 is connected so that it can be driven by the circuit W. Therefore, talking becomes possible when the switch is changed to a telephone set 28 on the receiving side, since the voices are outputted from the loudspeaker 19 if the calling side wants to make talking with the receiving side.

Abstract: PROBLEM TO BE SOLVED: To fast execute information processing by utilizing a microprocessor by simultaneously performing operation processing of plural unit data with operation processing of one time. SOLUTION: A distribution pixel that occurs at the time of binarizing an attentional pixel A is added to a distribution error which is distributed to pixels D to G by binarization processing up to the preceding pixel by one (S1). Data that is preliminarily stored in a register 4 and data register stored in a register 3 are subjected to an AND operation in every bit by an 'AND instruction' and are stored in a register 2 (S2). D' is stored in an error buffer 52 (S3). The data of the register 2 is shifted to the right by eight bits through a '8-bit logic right shift instruction' and high order 8 bits are compensated (S4). That is, it is possible to simultaneously process (n) pieces of m-bit unit data by performing operation processing of word data which is divided by connection data of unit data.

Abstract: PROBLEM TO BE SOLVED: To provide a color scanner capable of high speed processing with high color reproducibility at low cost. SOLUTION: The reader is provided with an arithmetic section 106 that uses image data (a) of a current input line and image data (n) of one line- preceding read from a memory 104 in the same color as that of the input line to conduct a weight mean arithmetic operation and that outputs the arithmetic result. The reader is also provided with a parameter setting means (CPU 108) that sets a parameter (c) for the arithmetic operation to each reading of each color. The weighting means arithmetic operation is conducted by using the parameter (c) different from each color. Thus, an image without color slurring is obtained through a moving readway.

Abstract: PURPOSE: To provide an inexpensive facsimile equipment with high reliability and its decoding method without reducing recording speed by executing a decoding processing at a line unit in a time-division manner. CONSTITUTION: When the address of data given to CODEC 108 is first in a page, a page head is set in a DMA controller 104. But after another decoding is executed by a time division processing in the midst of the page, the address is set based on position information (that is, the word address of data and the bit position of the word) of data which is preserved at the point of time when preceding decoding is completed and decoding is started. Thus, two decoding processings are executed by time division.
