摘要： PURPOSE:To prevent the device from being left in a facsimile reception state as it is by providing a specific facsimile signal monitoring device to make an accurate detection even when a facsimile signal from a communication satellite is stopped to be switched to a music and voice signals. CONSTITUTION:When EOP signals showing the end of a facsimile transmission are transmitted from a communication satellite, they are detected by a facsimile monitoring circuit 30. A node r11 is restored by turning off a relay RL 1 after the lapse of a time t1. When the flag pattern of DCS signals showing the transmission start is detected again within the time t1, it is taken as the transmission of a new facsimile signal, continuing the reception mode. In the case the turning on and off of the carrier signal is repeated on the way, the timer for two hours is started when changing from turning 'on' to 'off' or from 'off' to 'on'. If the timer is timed up, or if the number of times of repeating turning on and off becomes more than the prescribed value, the carrier of the facsimile signal is judged to be disconnected.

摘要： PURPOSE:To detect a control signal by the time-up output of a time control means, by detecting change of a transmission signal to generate a pulse signal and by starting the time control means by this pulse signal. CONSTITUTION:Picture signal Sv is transmitted as transmission signal St from hybrid circuit HTB to transmission line L. Meanwhile, control signal Sc from the other party side is converted to pulses, which repeat H and L levels, through HYB by a BPF and waveform shaping circuit WF. Reset pulse generating circuit RPG detects change of the transmission signal to generate a reset pulse. The reset pulse resets FF1, and exclusive OR gate G3 becomes H only during the reset pulse period, and counter CT as a time control means is reset and is simultaneously started. Sc is detected by FF1 reset and FF3 set from the count start of CT. As a result, Sc is not detected during the transient response period of the BPF, and Sc is detected stably only when the transmission signal is not changed.

摘要： PURPOSE:To prevent the malfunction caused by the detouring signal, by inhibiting the output of the analog filter for the facsimile or the like for the period during which from transmission start of the transmission signal to the transient answer end of the analog filter after completion. CONSTITUTION:Phase signal (a) sent from transmission part 2 of transmission system T is transmitted to the telephone circuit from control part 10 via hybrid 1. Phase matching end signal (b) sent from the partner side is piled on signal (a) through circuit 1 and supplied to analog filter 3 of reception system R to extract signal (b). In this case, signal (d) is deliverd due to the effect of signal (a) and sliced via comparator 8 to be turned to signal (e) which is suppled to counter 9. In this instant, signal (f) is supplied to counter 9. In this instant, signal (f) is supplied to counter 9 from circuit 10 to inhibit the counting action then. Counter 9 delivers overflow signal (g) when the counting reaches the prescribed value.

摘要： PURPOSE:To surely deliver a message even if a called party is absent by providing a discrimination means discriminating whether or not a communication protocol is established with a caller facsimile transmitter after the automatic reply to an incoming call and a control means driving and recording a recording/reproducing means based on the result of discrimination. CONSTITUTION:When the operation is started at first, a ringer detector 2 discriminates whether or not an incoming call is a ringer incoming call through a line protection circuit 1. In the absence of the ringer incoming call, the equipment is in standby till the arrival of an incoming call and DC closing is applied in the presence of the incoming call. Then whether or not the 'absence mode' is discriminated. When a switch S1 is turned on (in the case of the absence mode), a timer (set to, e.g. 3sec) is started. Whether or not a remote signal is detected is discriminated. When no remote signal is detected, the equipment is in standby till the timer expires and after the expiration of the timer, the facsimile reception is transited. Whether or not the procedure attended with the reception, that is, the communication protocol is established is discriminated. When the communication protocol is established, a facsimile picture signal reaching a telephone line is recorded.

摘要： PURPOSE:To automatically execute the retransmission of an original even when any communication error is generated. CONSTITUTION:In this facsimile equipment, an original is read for each page, coded and afterwards stored in a memory 13, and a stored original information is transmitted for each page by originating a call to the opposite side facsimile equipment based on a phone number set in advance. When any communication error is detected while transmitting original information, a page of the original information under transmitting is stored and after the lapse of fixed time, header information is transmitted. Afterwards, the untransmitted original is automatically transmitted successively from the information of the original which page is stored. As the result, the burden of an operator is reduced.

摘要： PURPOSE:To get rid of any requirement to use any recording paper on which a residual quantity is marked by detecting the residual quantity of the recording paper through a relationship between the preset initial value and the counted value. CONSTITUTION:At time of setting a recording paper unit, a recording paper case is opened, and after installation, whether this case is closed or not is judged. When opening or closing of this recording paper case is carried out hereat, a recording paper residual quantity counter and a recording paper residual quantity detected value are set to zero each. Next, whether it is of feed of recording paper or not is judged, and if it is the recording paper feed, the recording paper residual counter is increased as much as 1, but if it is not the recording paper feed, the count is put back to the outset. Then, whether the recording paper residual counter's value is more than an optional number N or not is judged, and if the counter value is not more than the N, it is so judged that residual quantity is abundant, and thereby the count is put back to the outset, but if it is more than the N, the recording paper residual quantity detected value is set to 1, whereby such an alarm display as informing that there is no residual quantity, thus operation is over.

摘要： PURPOSE:To take up a slack in the recording paper, by exciting a predetermined phase of stator windings of a stepping motor by a predetermined number of pulses for fixation, then sequentially exciting different phases of the stator windings, and again exciting the predetermined phase for fixation, in a facsimile device or the like. CONSTITUTION:In response to an instruction 17 received, a controlling part 22 excites stator windings 26A, 26D of a stepping motor 15 by one pulse through a motor driving circuit 16. Next, by sequentially shifting the phase, the controlling part 22 excites stator windings 26A and 26B, 26B and 26C... 26C and 26D by one pulse each, thereby rotating a rotor 25 by one revolution. By this, an initial position of the rotor 25 is reset, and the first printing position of a recording paper is set, at the time of starting printing. At the same time, a slack in the recording paper is taken up, and accurate printing can be performed.

摘要： PURPOSE:To easily cut recording paper by recording a partition line distinguishing a received picture from a remaining recording picture onto the recording paper when an original whose size is smaller than the size of the set recording paper is received. CONSTITUTION:When a preliminary processing is finished (step 100), a recording paper size is discriminated (step 101), and suppose that a paper sheet of B4 size is loaded, a size of a received picture is discriminated (step 102). When it is discriminated that the received picture has a size A4, transfer of space (319-bit) and a black level (1-bit) is implemented (step 106). That is, in the case of the size B4, in total 2048 bits are required and since the size A4 needs 1728 bits in total, a space by the difference 320 bits is formed, and one bit in the space bits is allocated to a black level and the remaining bits are allocated to white levels to print out the space. When the transfer of data is finished, data transmission for one-line decoding processing is implemented (step 108) and whether or not the processing by one page is finished is discriminated (step 109), and when the processing is finished, a cut command line is recorded (step 110) and then a post processing (step 111) is implemented, Thus, the discrimination of the paper is made clear and the size of the paper is easily arranged.
