These are connected via buffer circuits BF _a1 , BF _a2 , BF _b1 , BF _b2 , BF _c , BF _m1 , BF _m2 , and the processors CPU _a , _{CPU b ,} CPU _m responds and realizes the aforementioned comprehensive functions.

[0010] The processor CPU _c is also connected to the operation unit OPP _C via interfaces I/F _C1 and I/F _C2 , and sends out display signals and accepts operation signals, as well as transmits and collects signals to the timer TIM. The collection/distribution time period is determined by the timing operation of the timer TIM, and during this time period, the power supply section PS is turned on via the power supply control section PSC, and power supply E is supplied to each section. It is supposed to be carried out. Note that the power supply unit PS can also be turned on and off via the power supply control unit PSC using the power switch of the operation unit OPP _C.

On the other hand, the processors CPU _a and CPU _b are connected to the line via modem devices (hereinafter referred to as modems) MDM _a and MDM _b and relay parts R EP _a and REP _b having a DC loop closing function, a dialing function, etc. L _a and L _b are connected, and automatic dialing units ADI _a and ADI _b are connected to relay units REP _a and REP _b to perform a dialing function. , collects the received image signals from the other party's FAX, temporarily stores the received image signals in the buffer memories BFM _a and BFM _b , sequentially transfers them to the storage unit MEM, stores them on the floppy disk FDD, and then sends them to the destination. A dial call is made to each FAX, image signals from the floppy disk FDD are temporarily stored in buffer memories BFM _a and BFM _b , and the contents thereof are transmitted. Further, the processor CPU _m controls the floppy disk FDD via the disk control unit FDC, and records the image signals etc. transferred from the buffer memories BFM _{a and} BFM _b to the floppy disk _FDD . The contents of the floppy disk FDD are read out in response to a request from the floppy disk FDD and transferred to the buffer memories BFM _a and BFM _b .

0012 Figure 3 (Figure 3) shows the FAX/TEF₁~TEF_nThis is a block diagram of the micro A processor such as a CPU, a fixed memory ROM, and a variable memory RAM are provided. These constitute a control section, and are stored in a fixed memory ROM. The processor CPU executes the instructions and accesses the necessary data to the variable memory RAM. It is designed to be controlled while accessing the system. In addition, a modem MDM, Relay part R with DC loop closing function and calling signal branching function from exchange EX Line L is connected via switch SW that switches between EP and telephone TEL. OPP, which also has a display function, and a document detector MDT, which will be described later.₁ ,MDT ₂ , separator detection unit SDT, home position detector HDT, etc. are connected. On the other hand, the motor control unit MCT directly converts characters, figures, etc. on the document into image signals. a reading unit RED, and a recording unit that records on recording paper according to the received image signal. The motor control unit MCT and the driver DR are connected to the motor control unit MCT and the driver DR._m,DR_s,D R_rMotor M used for main scanning during transmission and reception_m, used for sub-scanning during transmission Motor M_s, and a motor M used for sub-scanning during reception._rbecomes the driving force. ing.

[0013] Furthermore, the detection output of the incoming call detection unit RDT, which detects a ringing signal such as 16H _Z given via the relay unit REP, and the output of the power switch S are transmitted via the power supply control unit PCT and the interface I/F, In response to the arrival of a call signal, the processor CPU controls the power supply unit (not shown in the figure), turns on the power supply to each unit other than the self-controller and the variable memory RAM, and turns on the power switch. According to the operation of S, the power supply is similarly turned on and off. Therefore, if the switch SW is set to the repeater REP side, the entire unit will be in operation in response to an incoming call, and in the case of receiving a call, the motors M _m and M _s will start, and the image signal from the reading unit RED will be transferred to the modem MDM and M s. It will be transmitted via the relay unit REP, and in the case of distribution, the recording unit REC will record on recording paper according to the received image signal via the relay unit REP and modem MDM. However, on the operation panel OPP, the destination, page number, number, etc. of the document are set, and these are stored in the variable memory RAM, and prior to transmitting the image signal, this document information is transmitted as numerical data. It has become something that If you do not rely on collection and distribution by the central device CE, you can make a dial call using the telephone TEL, establish a line connection with the other party's fax machine, and then perform individual transmission or reception by operating the operation panel OPP. .

FIG. 4 shows the mechanical configuration of the reading unit RED, in which (A) is a plan view of the main part, and (B) is a side view mainly showing the document path, and shows the width l of the document 1. The document ₁ loaded between the document guides 2 _a and 2 _b whose facing distance is set according to the document guide 1 is placed between the fixed guides 3 _{a and} 3 which are arranged facing each other according to the maximum allowable value of the document l ₂ . The document ₁ is transported in the direction of the arrow by the feed roller 4, the feed roller 5, the pinch roller 6, and the reading roller 7, which rotate in the direction of the arrow. Characters, figures, etc. are converted into electrical signals, and after undergoing predetermined processing, are given to the processor CPU as image signals. However, the document 1 can be stacked and loaded in multiple sheets, and as the transmission starts, the document is transferred sequentially starting from the lowest layer, and image signals are transmitted for each document. It has become a thing.

Further, a document detector MDT ₁ consisting of a lever, a light-emitting element, a light-receiving element, etc. is provided approximately in the middle of the fixed guides 3 _a and 3 _b on the lower surface side, and the presence or absence of the document 1 is detected by this. , the processor CPU determines whether or not to enter the transmission state according to the detection output of the photoelectric sensor RDS, and the photoelectric sensor RDS is provided with opposing sensors on the side of the feed roller 5 and approximately in the center of the document path. A document detector MDT ₂ consisting of a light-emitting element, a light-receiving element, etc. is provided, which detects the leading edge of the document 1, and in response to this detection output, the processor CPU instructs the photoelectric sensor RDS to start a reading operation. It has become a thing.

[0016] Therefore, the originals 1 are classified by destination into original groups each consisting of one or more sheets, and between the original groups, as shown by the broken line, a maximum group allowable width l ₂ made of Kent paper or the like is inserted. If the separators 8 are inserted and stacked alternately, each time the transmission of each document group is completed, the separators 8 are also transferred in the same way as the document 1, and the separators 8 are transferred to the feed roller 5 side of the photoelectric sensor RDS and the maximum allowable width l. By providing a separator detector SDT similar to the document detector MDT ₂ near the inside of the document detector ₂ , the separator 8 is detected, and in response to this detection output, the processor detects that all documents in one document group have been transmitted. The CPU can now make a judgment, and using this, when a group of documents has been sent in response to a collection, it stops the sending operation according to the detection output of the separator detector SDT and shifts to a standby state. Control will be carried out.

[0017] FIG. 5 is a front view of the main parts of the operation unit OPP, and in this example, the destination and The number of pages for each manuscript group can be set from 1 to 10. When the first group of documents is loaded into the specified position, this is the document detector MDT.₁ detected by , set indicator PL_Slights up, and the set key K is pressed accordingly._SBy operating , the number of pages Indicator light PL_nlights up, and then press the number key K accordingly.₁~K_TenNumber of pages of manuscript group from inside When you operate the corresponding one, the numeric indicator PL₁ ~PL_TenThe corresponding item inside lights up. After confirming this, press the page number key K._n When you operate, the page number value changes to variable memory RAM. At the same time, the destination indicator PL_a lights up, and number key K is pressed accordingly.₁ ~ K_TenIf you operate the items corresponding to each destination inside, the numeric indicator light PL₁ ~PL _Ten The corresponding one inside will light up, confirm this and then press the destination key K._a When you operate each Each numerical value indicating the number of each destination is stored in the variable memory RAM, and the light goes out. Set indicator light PL_S lights up again.

[0018] Therefore, place the separator above the first group of documents, and then load the next group of documents. and perform the same operation, and then place the separator and load and synchronize the document group. By repeating the above operations, the number of pages and pages for each document group up to the maximum allowable number of stacks can be Numerical data for each destination is stored in variable memory RAM in correspondence with each document group, and this For example, in addition to adding document numbers according to the loading order, document information is added to each group of documents. sent as information.

[0019] FIG. 6 is a diagram showing the transmission status of manuscript information, in which the processor CPU If it is determined that the call is for collection, it is sent from the variable memory RAM before sending the image signal. Read each data of the original document group to be processed, sequentially feed them to the modem MDM, and send the image information. The carrier wave for signal transmission is modulated by each data of the manuscript information and then transmitted. Ru.

[0020] That is, a frequency of, for example, _2100Hz is used as a carrier wave for image signal transmission, and a phase signal PH is transmitted at a frequency separate from this, and there is no image signal between them. The number of signal pixels is inserted according to the resolution, and for example, when the pixel is white, the phase of the carrier wave is 0°, and when the pixel is black, the phase is 180°, so the phase shift modulation is performed. Each time slot corresponding to one frame of pixels between the signals PH is used as a bit for transmitting information other than the image signal, and in this case, a blank period of N ₁ bits is provided, followed by a blank period of N ₂ bits x 1. The period of 0 is defined as words W ₁ to _{W 3} , each N ₂ bit byte is assigned a numerical value from 1 to 10, and, for example, the logical value “0” is depicted as a phase of 0°, and “1” as a phase of 180°. It is modulated in the same way as the signal, and the word _W1 transmits each destination, the word _W2 transmits the page number, and the word _W3 transmits the manuscript number. Note that, for example, it is preferable to set N ₁ =40 bits and N ₂ =20 bits, but it is also possible to perform similar modulation for each single bit and transmit more various kinds of data.

FIG. 7 is a timing chart showing the collection and distribution status of the central device CE. For example, a dial call is made to FAX/TEF ₁ via line L _a , and a document is sent to this dial. If there is, the collection CC ₁ collects the original information and image signal based on the first original group, and sends the line L to multiple destinations included in the original information without collecting the next group of originals. _A and L _b are used to simultaneously make a dial call to each person, transmit an image signal in response to the response from the other party's FAX, and then perform the same operation for each other destination. After repeatedly performing distribution AC _1a and AC _1b , performing similar collection CC ₂ for the next FAX/TEF ₂ , and performing similar distribution AC _2a and AC _2b in response, Perform the same collection CC ₃ for the next FAX/TEF ₃ , perform the same distribution AC _3a and AC _3b accordingly, and repeat this until FAX/TEF _n , and go to the first FAX/TEF ₁ . Returning, the document information and image signals based on the next group of documents are collected and distributed, and this is repeated until FAX/TEF _n , and the same operation continues cyclically.

[0022] Therefore, every time a call is made for collection from the central device CE, only the first document among the groups of originals loaded in each FAX/TEF ₁ to FAX/TEF _n is sent for collection. This is repeated cyclically and sequentially for each FAX/TEF ₁ to FAX/TEF _n , so there is no opportunity for collection for each FAX/TEF ₁ to FAX/TEF _n . is equalized, and a significant delay is prevented from occurring at the time of collection for subsequent FAX. However, faxes that do not have a manuscript loaded will not be collected, but only those that have manuscripts will be collected. The processor CPU _C of the central equipment CE compares the numbers, and if there is a discrepancy, dials the fax that was collected, records a non-delivery message indicating the collection letter using the image signal, and sends the message to the handler. It is used to notify the occurrence of an abnormality. In addition, if the exchange EX is a private branch exchange, if the destination fax to which the non-delivery message should be sent is busy or does not respond due to a failure, etc., it will dial the other fax number specified in advance from the same or nearby department. In addition, a similar non-delivery message is sent in reverse black and white, and recorded by another FAX.

FIG. 8 is a general flowchart of the collection and delivery operation performed under the control of the control unit CNT in the central device CE, in which the processor CPU _C sets the "collection flag" to the variable memory RAM _C. After performing "Set", perform "Receive FAX address setting" in the address area of the same memory RAM _C , determine "Receive flag set?", and select from the address area according to YES. After performing "Receiving FAX address reading" and performing "Receiving processing" accordingly, "Receiving complete?" will be displayed as Y if the number of pages in the manuscript information matches the number of pages resulting from the reception. It is determined that the message has become ``receive flag reset'' and then returns to ``receive flag set?''.

[0024] Then, this time, since "receive flag reset?" is N (NO), "read delivery FAX address" is performed from the variable memory RAM _C that stores each destination in the manuscript information, and according to this, " After performing the "delivery processing", if "delivery completed?" is Y, it is determined whether "there are undelivered faxes?" based on the response status of the other party's fax, and depending on the N of this, the data is stored in the variable memory RAM _C. Configure the notification message settings to indicate that the delivery has been completed, perform notification processing on the notification message for the fax that received the message, and set the address area of variable memory RAM _C to ``receive fax.''"Address + 1" to update to the next one, perform "receive flag set", return to "receive flag set?", and repeat "receive processing" and "distribution process". However, in response to N for "Receive completed?" and Y for "Are there any undelivered faxes?", a "non-delivery message setting" is made in the variable memory RAM _C , and this is used to collect the faxes by "notification processing". sent to the fax that was sent.

[0025] FIG. 9 is a flowchart of "collection processing", and the processor CPU _a or processor CPU_b Under the control of the relay section REP_a or REP_b but" After making the line connection, the automatic dialing section ADI_a or ADI_b Due to the operation of A “dial call” is made, then the modem MDM_a or MDM_b specific laps from "Receive signal transmission" of the wave number is performed, and "receive confirmation signal received?" from the other party's fax is displayed. If it is Y, modem MDM according to the phase signal from the other party's FAX._a or MDM_b performs phase matching, and when "Phase matching complete?" becomes Y, the modem MDM_a or MD M_b "Phase matching completion signal is sent" from the fax machine, and in response, the other party's fax machine receives the document information. When the information is sent, assuming that the received image signal is Y for "1st page?" ``Receive manuscript information'', then press Y of ``Receive manuscript information?''_a or MDM_b ``Send confirmation signal'' from

[0026] Next, move to "Image signal reception", and in response to "Y" of "Document end signal received?", modem MDM_a or MDM_b ``Send document end response signal'' from ``Receive phase signal''. ? ” is Y, the steps after “Phase matching complete?” are repeated, and “Phase signal received?” is N. If the “Timeout?” becomes Y after a certain waiting time has elapsed, the relay unit REP _a or REP_b performs a “line disconnection”. In addition, if "Phase matching complete?" is displayed for a certain period of time within N, "Timeout?" is displayed. Even if the result is Y, "line disconnection" is performed.

FIG. 10 (FIG. 10) is a flowchart of the "concentration transmission process" based on the control of the processor CPU of FIG. 3, which is performed in correspondence with FIG. When this is done, the power is turned on to each part, the line connection is made by the relay unit REP, and the modem MDM sends a voiceless terminal response signal, followed by the message ``Receive a concentrating signal?'' If this is Y, the modem MDM sends a reception confirmation signal, and if the separator detector _SDT detects a separator? After that, the modem MDM sends out a phase signal, and then the motor M _m is further driven to feed the document to the reading position.

Next, if "Phase matching completion signal received?" becomes Y, "manuscript information transmission" is performed assuming "Y" of "1st page?", and "Sends manuscript information" in response to "Y of confirmation signal received?" If "1 page complete?" is Y, "Send original end signal" is performed, and according to "Receive original end response signal?" (Y), detect separator detector SDT. "Separator detected?" is determined according to the output, and if this is N, "Send phase signal" and subsequent steps are repeated assuming "Y" of "Document detected?" by document detector MDT ₁ , and "Separator detected?"'' becomes Y, it is assumed that all of one document group has been transmitted, and the line is disconnected and the power is turned off, and the process shifts to a standby state. In addition, when "Concentration signal received?" is set to N, "Distribution reception processing" described later is performed, while "Phase matching completion signal received?" is set to N, a certain amount of time passes and "Timeout?" becomes Y. If so, the status changes to "line disconnected".

FIG _. 11 (FIG. 11) is a flowchart of the "distribution process _" in _{FIG .} After a "dial call" is made to each individual, "distribution signal transmission" of a specific frequency is performed by modems MDM _a , MDM _b , and if "distribution confirmation signal received?" is Y, modems MDM _a , MDM _b "Phase signal transmission" is performed, and when "Phase matching completion signal received?" becomes Y, "image signal reading" is performed from the floppy disk FDD, "image signal transmission" is performed, and "1 page In response to Y of ``End?'', ``Send original end signal'' is performed, and in accordance with Y of ``Receive original end response signal?'', if ``Send all pages?'' becomes Y, ``line disconnection'' is performed. In addition, if a certain period of time has elapsed for "Delivery confirmation signal received?", "Phase matching completion signal received?" and "Manuscript end response signal received?" within N, and "Timeout?" becomes Y, "Line disconnection" occurs. ”.

[0030] FIG. 12 (FIG. 12) is based on the control of the processor CPU in FIG. 3, which corresponds to FIG. 11. This is a flowchart of the ``distribution reception process'' in which the ``incoming call'' is detected by the incoming call detection unit RDT. When "detection" is performed, "power is turned on" to each part, and the relay part RE A “line connection” was made by P, and a “voiceless terminal response signal was sent from the modem MDM. If "Send" is done and "Distribution signal received?" is Y, the modem MDM will transmit "Distribution signal". After the “confirmation signal transmission” is performed, the “phase matching complete?” with the incoming phase signal becomes Y. Then, after the modem MDM “sends the phase matching completion signal”, the “image signal The modem enters the "Receive" state, recording is performed, and the modem In addition to the "manuscript end response signal sent" from the MDM, "phase signal received?" If it is Y, repeat the steps after "Phase matching complete?" and "Phase signal received?" becomes N. If the “Timeout?” becomes Y after a certain period of time, “Line disconnected” and “Power off” will be displayed. ” is performed, and the device enters the standby state. In addition, if "Phase matching complete?" remains N and "Timeout?" becomes Y, immediately While the state changes to "Line disconnection", if "Distribution signal received?" is N, "Receive signal" in Figure 10 "Transmission processing" is performed.

[0031] FIG. 13 (FIG. 13) is a flowchart of the "notification process" in FIG. Correspondingly, the ``delivery reception process'' shown in Figure 12 is performed at the other party's fax machine. It becomes. That is, in FIG. 13, the relay section REP<sub>a</sub> or REP<sub>b</sub> "Line connection" by and automatic dialing section ADI<sub>a</sub> or ADI<sub>b</sub> A "dial call" was made by Yeah, modem MDM<sub>a</sub> or MDM<sub>b</sub> ``Delivery signal transmission'' is performed, and the other party F If “Delivery confirmation signal received?” from AX is Y, modem MDM_a or MDM _b "Send phase signal" from "Phase matching completion signal received" from the other party's fax machine. According to Y, the corresponding “Non-delivery message setting” in Figure 8 is displayed. ”, and if this is Y, “send non-delivery message” as an image signal, When “Is there a non-delivery message?” is N, it corresponds to “Notification message” in Figure 8. After sending the notification message using the image signal, the modem MDM_a or M DM_b ``Send original end signal'' and select Y for ``Receive original end response signal?'' Therefore, "line disconnection" is performed.

[0032] In addition, each message is sent with the characters ``futatsu'' or ``tsuutatsu,'' as well as the month, day, hour, minute, manuscript number, and fax number, etc. Recorded by FAX. Also, if the other party's fax machine is busy or has a problem, there is no proper response signal, and one of the "Delivery confirmation signal received?", "Phase matching completion signal received?", and "Document end response signal received?" remains N. If a certain period of time has passed and "Timeout?" becomes Y, "message black and white is reversed", "line disconnection", "line connection" is performed again, and the predetermined "dialing for another fax" is performed. After making a call, send a black and white inverted message. Therefore, for each FAX/TEF ₁ to FAX/TEF _n , the collection/delivery status can be checked by recording on the recording paper without adding any special configuration, and if the documents are not delivered, the document group can be reloaded. This makes it easier to take measures such as Additionally, if your own fax does not respond, a black and white message will be recorded on the other fax machine, making it easy for the person handling the other fax to identify the problem and report it to the person handling the unresponsive fax. This is particularly effective when using a private branch exchange.

In addition, according to the configuration of FIG. 1, FAX・TEF ₁ to FAX・TEF _n are used for both distribution reception and collection transmission, and have a broadcast transmission function via the central device CE. Therefore, the same document can be sent quickly and easily to multiple destinations, and depending on the configuration shown in FIGS. 3 to 5, groups of documents for different destinations can be loaded at the same time, making handling extremely easy. In addition, according to the information transmission system of FIG. 6, a large amount of data can be freely transmitted without adding special circuits to FAX-TEF ₁ to FAX-TEF _n .

[0034] However, in Figure 1, multiple exchanges EX are connected via relay lines, etc., and each FAX/TEF₁ ~FAX・TEF_n May accommodate sending only or receiving Mix dedicated faxes, include those that are only for sending in the target of receiving, and those that are only for receiving. It is the same even if the document is included in the distribution target, and the separator 8 in FIG. 4 has the same size as the document 1. A through-hole notch or marking is formed in a specific area using a standard tool, and this is inspected. The output is also the same, and the arrangement and arrangement of the separator detector SDT is changed accordingly. This can be done not only when transmitting concentrators, but also when using general one-to-one communication. The present invention can also be applied to direct transmission, or to a center FAX of a broadcasting device. In addition, the configurations shown in FIGS. 2 to 5 can be selected arbitrarily depending on the conditions, and the configurations shown in FIGS. In some cases, each bit or byte may constitute a binary code, etc. However, the same result can be obtained even if multiple frames over multiple periods of the phase signal PH are used for information transmission. Moreover, in FIG. 7, the line L_a ,L_b be used for collecting messages at the same time, or Continuously collect CC₁ ~CC₃ etc., and then start the distribution AC._1a, AC_1b~AC_3a, AC _3b etc. may be performed continuously, and the line L_a ,L_b Not only that, but also many more lines. The same applies when used for collection and distribution. In addition, in FIGS. 8 to 13, steps may be replaced or changed depending on the situation. The embodiments can be modified in various ways, such as omitting unnecessary steps.

[0035]
