Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The invention relates to a data communicating apparatus which can store a plurality of transmission data and has a function to collectively transmit the plurality of transmission data to the same destination. 
     2. Related Background Art 
     Hitherto, as such a kind of apparatus, for example, a facsimile apparatus has been known. 
     In the conventional facsimile apparatus, when an auto-dialing process by a designated telephone number is executed, if a plurality of transmission image data with the same telephone number designated is stored in a memory, such a plurality of transmission image data is collectively transmitted by an auto-dialing process of one time. That is, there are not preformed such processes that the auto-dialing process is executed every transmission image data and each transmission image data is transmitted by an individual communication, but the plurality of transmission image data is transmitted as a series of transmission data by the auto-dialing process of one time, thereby improving a transmitting efficiency. 
     However, according to the foregoing facsimile apparatus, since the transmission image data with the same telephone number to be automatically dialed is merely selected and is collectively transmitted, the plurality of transmission image data received is merely outputted as a series of image data at the receiver end to which the image data is collectively transmitted. 
     In a facsimile apparatus of the G3 standard of the ITU-T recommendation, image data with a subaddress signal or a password signal set therefor can be transmitted. Since the subaddress signal or password signal can be individually set to each transmission image data, in case of transmitting a partner destination such that one facsimile apparatus connected to one telephone line is shared by a plurality of users, a specific user in the plurality of users can be designated by the subaddress signal to transmit image data, and an access to only specific transmission image data can be limited by the password signal. 
     If the above construction such that a plurality of transmission image data is collectively transmitted in accordance with the telephone number to be automatically dialed is also simply applied to transmission image data with the subaddress signal or password signal set, the subaddress signal or password signal set in each transmission image data is transmitted without being ulitized. 
     SUMMARY OF THE INVENTION 
     It is an object of the invention to improve a data communicating apparatus in consideration of the foregoing problems. 
     Another object of the invention is that in the case where a plurality of data to be transmitted to the same destination set, a collective transmitting function to collectively transmit the plurality of data is provided, and in the case where first information (for example, subaddress signal) to distinguish (or identify) data to be transmitted or second information (for instance, password signal) to limit an access to the data set into such data, the collective transmitting process and the transmission of the first and second information can be properly executed. 
     Still another object of the invention is to provide a data communicating apparatus with in a plurality of data to the same destination, data with the same first or second information set is used as a target of a collective transmission. 
     Further another object of the invention is to provide a data communicating apparatus with in case of collectively transmitting data with the first or second information set, consistency of the first or second information is checked, and either (1) to change a communication mode and transmit the first or second information before transmission of each data, or (2) to transmit the data without changing the communication mode, is selectively executed in accordance with a check result. 
     The above and other objects and features of the present invention will become apparent from the following detailed description and the appended claims with reference to the accompanying drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Embodiments of the invention will now be described in detail hereinbelow with reference to the drawings. A facsimile apparatus will be explained as an example in the following embodiments. 
     FIG. 1 is a block diagram showing a construction of a facsimile apparatus according to an embodiment of the invention. 
     An NCU (network control unit)  2  is connected to a terminal of a telephone line in order to use a telephone network for data communication or the like and executes a connection control of a telephone exchange network, a switching to a data communication path, and a holding of a loop. When a signal level (signal line  20   a ) from a control circuit  20  is equal to “0”, the NCU  2  connects a telephone line  2   a  to a telephone set  4  side. When the signal level is equal to “1”, the NCU  2  connects the telephone line  2   a  to the facsimile apparatus side. In the ordinary state, the telephone line  2   a  is connected to the telephone set  4  side. 
     A hybrid circuit  6  separates a signal of the transmitting system and a signal of the receiving system, transmits a transmission signal from an adder circuit  12  to the telephone line  2   a  via the NCU  2 , receives a signal from the partner side via the NCU  2 , and sends to a modem  8  via a signal line  6   a.    
     The modem  8  executes modulation and demodulation based on V.8, V.21, V.27ter, V.29, V.17, and V.34 of the ITU-T recommendation. Each transmitting mode is designated by a signal line  20   c . The modem  8  inputs a signal outputted to a signal line  20   b , outputs modulation data to a signal line  8   a , inputs a reception signal outputted to the signal line  6   a , and outputs demodulation data to a signal line  8   b.    
     An ANSam send-out circuit  10  is a circuit to send out an ANSam signal. When a signal at the signal level “1” is outputted to a signal line  20   d , the ANSam send-out circuit  10  transmits the ANSam signal to a signal line  10   a . When a signal at the signal level “0” is outputted to the signal line  20   d , the send-out circuit  10  does not output any signal to the signal line  10   a.    
     The adder circuit  12  inputs information on the signal line  8   a  and information on the signal line  10   a  and outputs an addition result to a signal line  12   a . A reading circuit  14  reads an image of an original and outputs the read image data to a signal line  14   a . A recording circuit  16  sequentially records information outputted to a signal line  20   e  every line. 
     A memory circuit  18  is used to store raw information of the read data or coded information thereof or to store received information, decoded information, or the like. 
     When a call command pulse is generated to a signal line  20   g , a calling circuit  22  inputs telephone number information outputted to a signal line  20   f  and outputs a selection signal to a signal line  2   b.    
     A console unit (or operation unit)  24  has a one-touch dial, an abbreviation dial, a ten-key, a *•# key, a set key, a start key, a subaddress signal input key, a password signal input key, and other function keys. Information corresponding to the depressed key is outputted to a signal line  24   a.    
     A registration circuit  26  is a circuit such that when a plurality of memory transmissions exist in correspondence to a call destination and the password signals or subaddress signals differ, whether or not data can be transmitted as one communication, accompanied by a mode change, or not is registered via a signal line  26   a.    
     The control circuit  20  controls the collective communicating operation in each embodiment of the invention. Particularly, in the first embodiment, the control circuit  20  executes a control in a manner such that when a plurality of memory transmissions to the same destination are in a standby state, when the subaddress signal or password signal is the same, those information is collectively transmitted and when the subaddress signals or password signals differ, those information is not collectively transmitted. 
     FIGS. 2 to  4  are flowcharts showing a flow of the control of the control circuit  20  in the first embodiment. Processes shown in the flows of FIGS. 2 to  4  are executed when a microcomputer of the control circuit  20  performs a computer program stored in an ROM (read only memory) of the control circuit  20 . 
     First in FIG. 2, the operation is started in step S 0 . In step S 2 , in the case where a plurality of memory transmissions with the subaddress signals or password signals differ exist in correspondence to the call destination, the operator registers a fact that the information is transmitted by changing the mode in a collective communication, into the registration circuit  26  through the signal line  26   a  for all of the destinations. 
     In step S 4 , the CML is turned off by outputting a signal at the signal level “0” to the signal line  20   a . In step S 6 , a signal at the signal level “0” is outputted to the signal line  20   d , thereby setting a state with the ANSam signal is not sent out. 
     In step S 8 , the signal on the signal line  24   a  is inputted and whether the memory transmission has been selected or not is discriminated. When the memory transmission is selected, step S 12  follows. When the memory transmission is not selected, step S 10  follows and the other process is executed. The processing routine is returned to step S 4 . 
     In step S 12 , the signal on the signal line  24   a  is inputted and a destination to be called, the subaddress signal, and the password signal are stored. In step S 14 , the original information is read and coded and stored into the memory. 
     In step S 16 , a check is made to see if the storage of all of the original information into the memory has been finished. When it is not yet finished, step S 14  follows. If YES, step S 18  follows and a call is generated to the designated destination in step S 12  by using the calling circuit  22 . 
     In step S 20 , a signal at the signal level “1” is outputted to the signal line  20   a  and the CML is turned on. In step S 22 , a pre-procedure is executed. In this step, the SUB signal and PWD signal designated in step S 12  are transmitted. Further, when a new memory transmission is selected, the call destination, SUB signal, and PWD signal are registered and, after that, the transmission information is read and coded and stored into the memory. 
     Step S 24  shows a memory transmission. When a new memory transmission is also selected here, the call destination, SUB signal, and PWD signal are registered and, after that, the transmission information is read, coded and stored into the memory. 
     In step S 26 , whether the reading image is the original of the last page or not is discriminated. When it is the original of the last page, step S 30  follows. If NO, step S 28  follows. 
     Step S 28  shows an intermediate procedure. Specifically speaking, a PPS-MPS signal is transmitted and an MCF signal is received. 
     In step S 30 , a check is made to see if any other memory transmissions to the same destination exist. If YES, step S 32  follows. If NO, step S 36  follows. 
     In step S 32 , a check is made to see if the SUB signal and PWD signal set by the other memory transmission are the same as the SUB signal and PWD signal transmitted by the pre-procedure of the original information which has been transmitted so far. When they are the same, step S 34  follows. The new memory transmission is also set to a mode for perform the collective transmission and the processing routine advances to step S 28  mentioned above. 
     When either one of the SUB signal and the PWD signal differs, step S 36  follows. Step S 36  shows a post-procedure. Specifically speaking, a PPS-EOP signal is transmitted and an MCF signal is received. 
     The second embodiment of the invention will now be described. 
     In the second embodiment, when a plurality of memory transmissions to the same destination are in a standby state, if the subaddress signal or password signal is the same, those information is transmitted without changing the mode. When the subaddress signals or password signals differ, the mode is changed and the information is transmitted. 
     FIG. 5 is a flowchart showing a portion different from the first embodiment (FIGS. 2 to  4 ) in the control of the second embodiment as mentioned above. 
     In FIG. 5, step S 40  shows NO in step S 32 . In step S 42 , the intermediate procedure is executed. Specifically speaking, a PPS-EOP signal is transmitted, an MCF signal and a DIS signal are received, the subaddress signal and password signal set by the new memory transmission are transmitted as SUB, PWD, and DCS signals, and subsequently, a Tr•TCF signal is transmitted and a CFR signal is received. In step S 44 , the apparatus is set into a mode for performing the new memory transmission. In step S 46 , the processing routine advances to step S 28 . 
     The third embodiment of the invention will now be described. 
     In the third embodiment, the communication in the second embodiment mentioned above is executed and in the case where the subaddress signals or password signals differ and a communication error occurs by transmitting after the mode was changed, the collective transmission is executed for the subsequent same destination on the basis of the foregoing first embodiment. 
     FIG. 6 is a flowchart showing a portion different from the first and second embodiments (FIGS. 2 to  5 ) in the control of the third embodiment as mentioned above. 
     In FIG. 6, step S 60  shows step S 42  mentioned above. In step S 52 , since the PWD signal or SUB signal differs, the mode change by the operation in the second embodiment has been performed. However, a check is made to see if a communication error due to the mode change has occurred. If no communication error occurs, step S 54  (S 44 ) follows. When a communication error occurs, step S 56  follows. 
     In step S 56 , in the case where a plurality of memory transmissions to the relevant destination are in the standby state through the signal line  26   a  and their subaddress signals or password signals differ, it is stored in the registrative circuit  26  that not transmission as a collective communication accompanied by a mode change but re-calling after disconnection is executed. 
     In step S 58 , the processing routine advances to step S 4  mentioned above. After that, step S 60  shows NO in step S 32 . In step S 62 , the information on the signal line  26   a  is inputted and whether or not regarding the destination connected at present, such a mode is set that in the case where a plurality of memory transmissions exist and the password signals or subaddress signals differ, the information is transmitted as a collective communication with a mode change is discriminated on the basis of the contents registered in the registration circuit  26 . When the mode is set for the destination, step S 64  (S 42 ) follows. If NO, step S 66  (S 36 ) follows. 
     When an error occurs by the control of the second embodiment, the apparatus is switched to the control of the first embodiment, thereby enabling a certain communicating operation to be obtained. 
     In the above embodiments, although the facsimile apparatus of the stand-alone type has been described as an example, the invention is not limited to it. It will be obviously understood that the invention can be applied to a data communication control in an integrated data processing system in which, for example, a copying function, an electronic filing function, and further, a data processing function are combined with a communicating function. 
     As described above, so long as the same subaddress signal or password signal, since the mode is the same and the password is the same, the collective transmission can be performed. Therefore, by executing the collective transmission with respect to those memory transmission information, a covering range of the collective transmission can be widened. 
     In the communication to the same destination, even if the subaddress signals or password signals differ, the information can be transmitted as a collective communication and the communication costs can be reduced. 
     When a plurality of memory transmissions to the same destination are selected, so long as the same subaddress signal or password signal, the collective transmission is performed. Further, when the transmission of the different subaddress signal or password signal is selected, if possible, the mode is changed and the information is transmitted as a collective communication. If impossible, another communication can be carried out. The memory transmitting function can be flexibly operated. 
     The present invention is not limited to the foregoing embodiments but many modifications and variations are possible within the spirit and scope of the appended claims of the invention.
