Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to an image communication method and apparatus capable of recording an image in color and monochrome, and a memory medium to be used in the image communication method and apparatus. 
     2. Related Background Art 
     A conventional facsimile apparatus can be loaded, on an image recording means, with only one of a color ink (or toner) cartridge and a monochromatic ink (or toner) cartridge, and it has not been possible to interchange one of the color ink (or toner) cartridge and the monochromatic ink (or toner) cartridge with the other. 
     Also a communication rate has been informed to a destination of the image communication, regardless of the kind of the ink (or toner) cartridge. 
     However, in case of contemplating a facsimile apparatus with an interchangeable ink (or toner) cartridge, a recording speed varies according to the kind of the cartridge since the characteristics of the cartridge (such as the discharge amount of ink or toner) are different between the color ink (or toner) cartridge and the monochromatic ink (or toner) cartridge. 
     Consequently, in case of image reception and recording in parallel in such facsimile apparatus with an interchangeable ink cartridge, a time for reception processing has to be made longer in case the color ink cartridge is loaded on the recording means, in comparison with the case of the monochromatic ink cartridge, since the color ink cartridge has a smaller number of ink discharging nozzles than in the monochromatic ink cartridge. (It is noted that when the color ink cartridge is loaded, the image received by facsimile transmission is recorded monochromatically with the monochromatic nozzles.) 
     On the other hand, in case the received image is stored in a memory instead of the parallel reception/recording a communication time can be made shorter by means of informing a higher communication rate to the destination because the discharge of ink (or toner) is irrelevant. 
     SUMMARY OF THE INVENTION 
     An object of the present invention is to provide a communication apparatus capable of switching a communication process according to the characteristics of a printer. 
     Another object of the present invention is to provide a communication apparatus capable of switching the communication process according to the kind of the cartridge mounted on the printer. 
     Still another object of the present invention is to provide an image communication method and apparatus in which a memory reception process may be conducted in case of an auto reception mode, and in case of a direct reception mode, an image reception process may be effected with a communication rate to be informed to a partner station being variable according to the kind of a recording means (for example a color or monochromatic ink cartridge). 
     Still another object of the present invention is to provide an image communication method and apparatus in which a memory reception process may be conducted in case an image recording sheet is absent, and, in case the image recording sheet is present, an image reception process with a communication rate to be informed to the partner station being variable according to the presence or absence or the kind of the recording means (for example, a color or monochromatic ink cartridge). 
     Still another object of the present invention is to provide a memory medium storing a program for controlling the above-mentioned image communication method and apparatus.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Preferred embodiments of the present invention will be described in detail with reference to the attached drawings. 
     First embodiment 
     At first there will be explained a first embodiment of the present invention, with reference to FIGS. 1 to  6 ,  7 A and  7 B,  8 ,  9 A and  9 B,  10  to  14 ,  15 A and  15 B,  16  to  20 . FIG. 1 is a block diagram showing the configuration of a facsimile apparatus with a message telephone function, constituting an image communication apparatus of the first embodiment of the present invention. In this drawing, there are shown a CPU (central processing unit)  1  for controlling the entire apparatus according to a control program stored in a ROM (read-only memory) to be explained later, utilizing a RAM (random access memory) (not shown) as a work area; and a ROM (read-only memory) for storing the control program for controlling the present apparatus; a MODEM  3  for modulating a digital signal from the CPU  1  into an analog signal for transmission to a telephone line  19  and demodulating an analog signal received from the telephone line  19  into a digital signal for transfer to the CPU  1 . 
     There are also provided a network control unit (NCU)  4  for connection control such as issuance or reception of a call to or from the network and for reconnection or disconnection of the line; a message telephone unit (TEL)  5 ; a speaker  6 ; a base unit (cordless base unit)  7  for a cordless telephone unit (subsidiary phone, not shown) provided as an accessory to the present apparatus, the base unit being provided in a single unit or in plural units; a cross point  8  constituting switching means for selectively connecting the telephone unit  5 , the speaker  6  and the cordless base unit  7  to the telephone line  19 ; a reading unit  9  for scanning an original in case of transmission or copying thereof; a gate array  10  to which are connected the CPU  1 , the NCU  4 , the recording unit  11 , a DRAM  12 , a flash memory  13 , a cartridge sensor  14 , a recording sheet sensor  15  and a panel gate array  16 . 
     A recording unit  11  serves to record an image to be copied image or an image received from a partner apparatus in the facsimile communication, by an ink jet recording method, a laser recording method, a thermal recording method, etc. In a case of the ink jet recording or the laser recording, an ink (or toner) cartridge is interchangeable between a color cartridge and a monochromatic cartridge. In the present embodiment, the image received in the facsimile communication is monochromatically recorded even when the color ink (or toner) cartridge is utilized, while the image to be copied is recorded in color. 
     In the following description, it is assumed that the present embodiment employs the ink jet recording method. 
     The recording unit  11  is provided with a support member (not shown) for supporting the cartridge. The recording unit  11  utilizes an ink jet recording head, in which plural nozzles are aligned along sub scanning direction to form a recording face of the recording head. The arrangements of the recording nozzles of different colors of this type of recording head in a transporting direction of a recording sheet and main and sub scanning directions are shown in FIGS. 19 and 20, respectively. Referring to FIG. 19, the recording head is provided with 64 nozzles for recording the black color (K), aligned in the sub scanning direction. In case of color recording, only 24 nozzles are used among the 64 nozzles, while, in case of monochromatic recording, all the 64 K nozzles are used. In parallel with the K nozzles, there are provided 24 nozzles respectively for cyan (C) color, magenta (M) color and yellow (Y) color, in the order of C, M and Y. In case of color image recording, the recording operation is initiated after all the image data are accumulated for 24 nozzles for each of C, M, Y and K colors. A carriage supporting the recording head is reciprocated in the main scanning direction, perpendicular to the direction of the array of the nozzles, to form an image in an area corresponding to the recording width of the plural nozzles. Thereafter, the recording sheet is transported in the sub scanning direction by the recording width, and the image is formed on the recording sheet by repeating the recording operation in the above-explained manner. The recording head employed in the present embodiment is an ink cartridge incorporating therein ink tanks. A monochromatic ink jet cartridge shown in FIG. 20 is provided with 128 nozzles for recording the black (K) color. 
     The DRAM  12  serves to temporarily store a predetermined amount of image data, in case of recording a received image or a copy image. The flash memory  13  is used for storing the received image in case of an auto-reception mode or in case the image recording sheet is absent and an user supplements recording sheets, and also for storing the message from a partner in a message telephone mode, and is therefore used in common by the facsimile apparatus and by the message telephone unit  5 . The cartridge sensor  14  detects the presence or absence of the ink (or toner) cartridge on the recording unit  11  or the kind (color or monochromatic) of the cartridge. The recording sheet sensor  15  detects the presence or absence of the recording sheet for image recording. The panel gate array  16  serves to connect the operation unit  17  and the display unit  18  with the gate array  10 . The operation unit  17  is provided with various keys to be used by the user for operating the present apparatus. The display unit  18  is used for displaying various information for the user. There is also shown a telephone line  19 . 
     FIG. 2 shows the details of the operation unit  17  and the display unit  18 . The display unit  18  is provided with a display unit  18   a , composed of for example, a liquid crystal display (LCD) unit, for displaying the date, error warnings, operation procedure, function status, etc. The display unit  18   a  may also be composed, for example of LED&#39;s (light emitting diodes) instead of the LCD. 
     Referring to FIG. 2, the operation unit  17  is provided with numeral keys  17   a , a response message key  17   b , a monochromatic copy key  17   c , a color copy key  17   d , a transfer/call key  17   e , a redial/pause key  17   f , a catch-phone/short-cut dial key  17   g , an on-hook key  17   h , a volume adjustment and selection key (volume/selection key)  17   i , an erasure key  17   j , a hold/message reproduction key  17   k , a message record/reproduction key  17   m , a function key  17   n , a mode selection key  17   o , a stop key  17   p , a FAX key  17   q  and a set key  17   r.    
     The numeral keys  17   a  are used for entering a number such as a telephone number or a number of copies to be made. The response message key  17   b  is used for recording the voice of the partner during speech communication, reproducing thus recorded voice, recording a replay message to another user in case of the user is absent, or reproducing the recorded message. The monochromatic copy key  17   c  is used in case of recording the image in monochromatic manner. The color copy key  17   d  is used in case of recording the image in color. The transfer/call key  17   e  is used for calling, from the present apparatus or from the cordless subsidiary telephone unit, another subsidiary telephone unit or transferring a channel during speech communication. The redial/pause key  17   f  is used for calling again a partner called most recently, or forming a predetermined pause (for example30 seconds) in the course of dialing. 
     The catch-phone/short-cut dial key  17   g  is used for utilizing the “catch-phone” service provided by NTT, enabling to accept an incoming call in the course of another call, or for short-cut dialing. The on-hook key  17   h  is depressed for effecting on-hook. The volume/selection key  17   i  is used for selecting a setting item or adjusting the loudness of a call tone of the message telephone unit  5  or a volume of a voice of a telephone handset. In order to use the volume/selection key  17   i  for function selection, the function key  17   n  is at first depressed, whereby the display unit  18  displays, for example, the “reception mode”. The volume/selection key  17   i  is then depressed to alter the display in the display unit  18  in succession. For example, in order to set the telephone number of the user, the volume/selection key  17   i  is repeatedly depressed until a message “Your telephone number” is displayed. On the other hand, in order to use the volume/selection key  17   i  for volume adjustment, the function key  17   n  is not depressed. The loudness of the call tone of the message telephone unit  5  varies if the volume/selection key  17   i  is depressed during telephone communication, but the volume of the voice from the headset of the message telephone unit  5  varies if the volume/selection key  17   i  is depressed during the telephone communication. 
     The erasure key  17   j  is used for shifting to a process for erasing the facsimile reception image recorded in the flash memory  13  and the messages recorded in the message telephone unit  5 . The hold/message reproduction key  17   k  is used for temporarily holding the line in communication or reproducing all the messages recorded in the message telephone unit  5 . The message record/reproduction key  17   m  is used for setting the present apparatus in the message telephone mode or resetting such mode, and for reproducing only the unreproduced message in case resetting the message telephone mode. The function key  17   n  is used for selecting various functions, in case of using the hold/message reproduction key  17   k  or the message record/reproduction key  17   m  in order to reproduce the message recorded by the message telephone unit  5 . The mode selection key  17   o  is used for selecting a standard mode or a fine mode in case of reading an original in the facsimile transmission or in the copying. The stop key  17   p  is used for stopping various operations when necessitated. The FAX key  17   q  is used in case of facsimile transmission or manual facsimile reception. The set key  17   r  is used, for example, when the data input on the operation unit  17  is completed. 
     In the following there will be explained, with reference to flow charts shown in FIGS. 3 to  18 , an operation of the above-explained image communication apparatus of the present embodiment. 
     At first there will be explained, with reference to FIGS. 3 to  6 , an operation of the image communication apparatus when a call is received from a partner. 
     At first the NCU  4  detects a CI signal (calling signal) (step S 301  in FIG.  3 ), and, when the handset of the present apparatus or the subsidiary telephone unit is off-hook (step S 302 ), a speech mode is set (step S 601  in FIG.  6 ). If the FAX key  17   q  is depressed during the speech communication, the mode is shifted to a manual reception mode (step S 603 ). When the reception is completed, the NCU  4  disconnects the line (step S 604 ) whereby a speech mode process is terminated. If the handset is on-hook (step S 605 ) without the depression of the FAX key  17   q  (step S 602 ) in the course of the speech communication, the NCU  4  disconnects the line (step S 604 ) whereby the speech mode process is terminated. 
     If the handset of the present apparatus or the subsidiary telephone unit is not off-hook in the step S 302  in FIG. 3, the CPU  1  discriminates whether the present apparatus is set at the message telephone mode (step S 303  in FIG.  3 ). The mode of the present apparatus is set by the user, utilizing the function key  17   n , the volume/selection key  17   i  and the message record/reproduction key  17   m , and the set mode is judged by the CPU  1 . 
     In case the step S 303  in FIG. 3 identifies that the present apparatus is set at the message telephone mode, if the CI signal is received twice or five times (step S 307 ), there is discriminated the capacity of the flash memory  13  (steps S 310 , S 311 , S 312 ). If the recording of the message and the memory reception in the facsimile communication are possible, there is transmitted a first OGM (outgoing message such as, in case of the message phone mode, “User is absent now. Please record your name and message by phone after a signal tone has been issued, please or transmit your message by facsimile”) thereby informing a caller that the user is absent and also that the facsimile transmission is possible (step S 313  in FIG.  3 ). Also if the memory recording alone is possible, a second OGM is transmitted to inform the caller that the message recording alone is possible and it is requested that the facsimile transmission may be tried later (step S 314 ). Also if the facsimile reception alone is possible, a third OGM is transmitted to request the facsimile transmission and to request to relay the speech communication later (step S 315 ). Also in case the message recording and the memory reception of the facsimile image are both not possible, a fourth OGM is transmitted to request to re-dial or retry the facsimile transmission (step S 316 ). 
     The discrimination of the capacity of the flash memory  13  is achieved by the CPU  1 , which constantly monitors the state thereof. The OGM mentioned above is transmitted to the telephone line  19 . 
     In case the step S 307  in FIG. 3 identifies that the number of received CI signals is twice or less than 5, or in case the step S 303  identifies that the present apparatus is not set at the message telephone mode, the CPU  1  discriminates whether the present apparatus is set at an auto reception mode. If not, the CPU  1  discriminates whether the CI signal has been received 15 times, and, if received, the CPU  1  informs that the user is unable to respond to the call (step S 306 ), and transmits different OGM&#39;s according to whether the message recording is possible and whether the memory reception is possible (steps S 313 -S 316  in FIG.  3 ). If the step S 305  identifies that the CI signal has not been received 15 times, the sequence returns to the step S 302  in FIG.  3 . 
     In case the step S 304  in FIG. 3 identifies that the present apparatus set at the auto reception mode and the step S 308  identifies that the memory reception is possible, the CPU  1  discriminates whether the CI signal has been received at least twice (step S 309 ), and, if not received, the sequence proceeds to the step S 305  in FIG.  3 . Also if the step S 308  identifies that the memory reception is not possible, the sequence proceeds to the step S 306  in FIG.  3 . 
     In case the step S 309  identifies that the CI signal has been received twice or more, the CPU  1  discriminates whether the present apparatus is set at the auto reception mode (step S 401  in FIG.  4 ), and, if set, the CPU  1  discriminates whether the memory reception is possible (step S 402 ). If the present apparatus is not set at the auto reception mode or if the memory reception is not possible, the sequence proceeds to the step S 306  in FIG.  3 . 
     In case the above-mentioned step S 402  in FIG. 4 identifies that memory reception is possible, the apparatus is shifted from the message telephone mode to a facsimile mode (F/T conversion; step S 403 ) and an OGM is transmitted to prompt the facsimile transmission and requests that the message communication may be tried later (step S 404 ). Then, for calling for the user, the MODEM  3  transmits a pseudo CI signal to the partner through telephone line  19  (step S 405 ). 
     After the transmission of the OGM, the CPU  1  monitors a CNG signal (initial identification signal) indicating a facsimile terminal from the partner (step S 406 ). If the CNG signal is detected, the OGM transmission is terminated (step S 513  in FIG.  5 ), then the automatic reception (memory reception) is executed (step S 514 ), and the NCU  4  disconnects the line (step S 508 ). Also in case the on-hook state of the partner is detected before the CPU  1  detects the CNG signal (step S 407  in FIG.  4 ), the NCU  4  disconnects the line (step S 508  in FIG.  5 ). If the pseudo CI signal is detected 7 times (step S 408  in FIG.  4 ), the sequence proceeds to the step S 306  in FIG.  3 . Also if the step S 408  identifies that the pseudo CI signal has not been received 7 times, the sequence returns to the step S 406  in FIG.  4 . 
     After the transmission of the OGM in the steps S 313 -S 316  in FIG. 3, if the CNG signal is detected (step S 501  in FIG. 5) and if the memory reception of the facsimile image is possible (step S 512 ), the CPU  1  terminates the OGM transmission (step S 513 ), and executes the memory reception (step S 514 ), thereby storing the received image in the flash memory  13 . Upon completion of the reception, the NCU  4  disconnects the line (step S 508 ). Also in case the step S 512  in FIG. 5 identifies that the memory reception is impossible, the OGM transmission is terminated (step S 515 ) and the NCU  4  disconnects the line (step S 508 ). 
     In case the step S 501  in FIG. 5 does not detect the CNG signal, the CNG signal is monitored (step S 501 ) until the OGM transmission is completed (step S 502 ). In case the CNG signal is detected, the sequence proceeds to the step S 512  in FIG.  5 . If the CNG signal cannot be detected before the completion of the OGM transmission, the CPU  1  discriminates whether the message recording is possible, and, if possible (step S 503  in FIG.  5 ), the message recording is executed (step S 504 ). Even in the course of the message recording, the CPU  1  monitors the CNG signal (step S 505 ). 
     If the CPU  1  does not detect the CNG signal (step S 505  in FIG. 5) and does not detect the completion of the recording (step S 509 ), the sequence returns to the aforementioned step S 504 . If the completion of the recording is detected (step S 509 ), the NCU  4  disconnects the line (step S 508 ). Also if the CPU  1  detects the CNG signal, whether the memory reception is possible is discriminated (step S 506 ), and, if not possible, the NCU  4  disconnects the line (step S 508 ) after the completion of the recording (step S 509 ). 
     On the other hand, in case the step S 506  in FIG. 5 identifies that the memory reception is possible, the CPU  1  resets the message recording mode and continues the memory reception (step S 507 ), and the NCU  4  disconnects the line after the reception is completed (step S 508 ). Also in case the step S 503  in FIG. 5 identifies that the message recording is not possible, the CPU  1  discriminates whether the memory reception is possible (step S 510 ), and, if possible, the memory reception is executed (step S 511 ) and the NCU  4  disconnects the line after the completion of reception (step S 508 ). Also in case the step S 510  in FIG. 5 identifies that the memory reception is not possible, the NCU  4  disconnects the line without any process (step S 508 ). The cutting-off of the connection in the step S 508  completes the serial process in response to the call received from the partner. 
     In the following there will be explained, with reference to FIGS. 7A and 7B, a direct receiving operation for the facsimile image. In such direct reception operation, the user is assumed, in response to a call received from the partner, to off hook the handset of the message telephone unit  5  or of a cordless telephone unit (not shown). 
     In response to a call received from the partner, the CPU  1  discriminates whether the present apparatus is set at the auto reception mode (step S 701 ). If set, an ordinary facsimile procedure is executed to detect the CNG signal (step S 702 ), declare a communication speed of 900 bps by a DIS (digital identification signal) from the MODEM  3  to the partner (step S 703 ), store the received image in the flash memory  13  (step S 704 ) and disconnect the line by the NCU  4  as a post-procedure for terminating the present process. 
     In case the aforementioned step S 701  identifies that the present apparatus is not set at the auto reception mode, the CPU  1  discriminates whether the handset of the message telephone unit  5  or of the cordless telephone unit is on hook. If on hook, the NCU  4  disconnect the line as the post-procedure (step S 719 ) and the present process is terminated. If off hook, the CPU  1  discriminates whether the FAX key  17   q  is depressed (step S 706 ). If the FAX key  17   q  is not depressed for a predetermined time, an error message for requesting the depression of the FAX key  17   q , for example, is given to the user by the display unit  18  or by the speaker  6  (step S 710 ), and the sequence returns to the aforementioned step S 705 . 
     On the other hand, if the aforementioned step S 706  identifies that the FAX key  17   q  is depressed, the CPU  1  discriminates whether the present apparatus is set at the direct reception mode (step S 707 ). The direct reception mode can be set by the user through the operation unit  17 . If not set at the direct reception mode, the present apparatus shifts to the auto reception mode and declares a communication speed of 9600 bps by sending the DIS signal to the partner (step S 703 ). If set at the direct reception mode, the cartridge sensor  14  discriminates whether an ink (or toner) cartridge for image recording on the recording sheet is loaded on the recording unit  11  (step S 708 ). If the ink cartridge is not loaded, an error message indicating the absence of the ink cartridge is given to the user (step S 710 ) and the sequence returns to the aforementioned step S 705 . 
     In case the ink (or toner) cartridge is loaded in the recording unit  11 , the recording sheet sensor  15  discriminates the presence of the recording sheet (step S 709 ). If absent, an error message indicating the absence of the recording sheet is given to the user (step S 710 ) and the sequence returns to the aforementioned step S 705 . If the recording sheet is present, the cartridge sensor  14  judges the kind (color or monochromatic) of the ink (or toner) cartridge loaded in the recording unit  11  (step S 711 ). If a monochromatic ink cartridge is loaded in the recording unit  11 , the MODEM  3  declares it to the partner by the DIS as a pre-procedure of the facsimile communication protocol that the communication can be executed with a speed of 4800 bps (step S 712 ). On the other hand, if a color ink cartridge is loaded in the recording unit  11 , the MODEM  3  declares it to the partner by the DIS as the pre-procedure of the facsimile communication protocol that the communication can be executed with a speed of 2400 bps (step S 713 ). 
     In the following it will be described that the communication speed declared to the partner in the present embodiment is different depending on the mode set in the present apparatus or the kind of the ink (or toner) cartridge loaded in the recording unit  11 . 
     The number of the nozzles discharging the black ink is different between the monochromatic and color ink cartridges and is less in case of the latter. Consequently, the amount of recording at a time is also less in case of the latter. In the direct receiving operation in which the image is simultaneously received and recorded, if the communication speed is higher than the recording speed, the amount of image data transmitted per unit time from the partner becomes larger than the amount of the recorded image data to induce an overflow of the memory, whereby the receiving apparatus becomes unable to process the images transmitted in succession. On the other hand, the monochromatic cartridge can record a larger amount at a time in comparison with the color cartridge and can therefore cope with the communication speed to a certain level. 
     In the memory reception mode, the maximum communication speed of the apparatus can be utilized since the received image is stored in the memory without being recorded. 
     For this reason, the communication speed declared to the partner is varied depending on the selected mode or the kind of the ink (or toner) cartridge. 
     After the declaration of the communication speed in the aforementioned steps S 712  and S 713 , the received image is stored in the DRAM  12  (step S 714 ). 
     In case of manual reception, since there is executed direct reception where the image is recoreded while it is received, the capacity of the DRAM  12  is smaller than that of the flash memory  13 . More specifically, though the nominal capacity is 4 MB both in the DRAM  12  and the flash memory  13 , the capacity of the DRAM  12 , being only partly used, is less than that of the flash memory  13 . 
     When the received image of a predetermined amount is stored in the DRAM  12  (step S 715 ), it is transferred to the recording unit  11  and recorded on the recording sheet (step S 716 ). After the transfer of the received image to the recording unit  11 , the DRAM  12  becomes empty, and then another image is received from the partner and is stored in the DRAM  12 . These procedures are repeated until the entire image from the partner is received and recorded. After the recording of all the pages, the communication is terminated (step S 717 ), and the NCU  4  disconnects the line as the post-procedure (step S 719 ) to terminate the present sequence. In case the recording sheet sensor  15  detects that the recording sheet is exhausted in the course of recording of the received image (step S 718 ), a reception error is informed to the partner and the NCU  4  disconnects the line as the post-procedure (step S 719 ) to terminate the present process. If the aforementioned step S 718  identifies the presence of the recording sheet, the sequence returns to the aforementioned step S 714  to store the received image in the DRAM  12 . 
     The serial process for direct reception is completed in the above-explained manner. In case the aforementioned step S 708  identifies that the ink (or toner) cartridge is not loaded in the recording unit  11 , it is also possible to shift to the automatic reception if a surplus capacity is available in the flash memory  13  and to inform the user of the fact that an unrecorded portion of the image is stored in the flash memory  13 . 
     In the following there will be explained, with reference to flow chart in FIGS. 8 to  12 , recording and erasing processes for the facsimile image received in the memory reception mode. 
     If a new image is received by memory reception, the fact of such reception and the number of received facsimile cases are displayed on the display unit  18  and informed to the user, so that the user can recognize the memory reception without any particular operation. This procedure will be explained with respect to FIG.  8 . 
     The CPU  1  discriminates whether the received facsimile image is stored in the flash memory  13  (step S 801 ), and, if not stored, the present sequence is terminated without any process. If stored, the CPU  1  discriminates whether the facsimile image is still unrecorded (whether unrecorded pages still exist) (step S 802 ) The judgment whether the facsimile image is still unrecorded is made by setting a pointer corresponding to the received image at the reception thereof and checking such pointer by the CPU  1 . 
     If the aforementioned step S 802  identifies the absence of the unrecorded pages, the present sequence is terminated without any process. If an unrecorded page is identified, the CPU  1  causes the FAX key  17   q  to flicker (step S 803 ). The FAX key  17   q  is composed of a translucent key member where a light emitting member such as a light emitting diode is mounted. 
     Then the CPU  1  discriminates whether the unrecorded page has been recorded (step S 804 ), and, if not, continues the flickering of the FAX key  17   q  (step S 803 ). If recorded, the CPU  1  terminates the flickering of the FAX key  17   q  (step S 805 ) and the present sequence is terminated. 
     Though not illustrated in FIG. 8, it is also possible, in case an unreproduced message remains, to construct the message recording/reproduction key  17   m  in the same manner as the FAX key  17   q  and to cause such message recording/reproduction key  17   m  to flicker. 
     In case the user wishes to recognize the memory reception and record the image received by the memory reception, the user depresses the FAX key  17   q  on the operation unit  17 . The operations in such case will be explained in the following with reference to FIGS. 9A and 9B. 
     The CPU  1  discriminates whether the FAX key  17   q  is depressed, until such depression takes place (step S 901 ). When the FAX key  17   q  is depressed, the CPU  1  discriminates whether the facsimile image received by the memory reception is present in the flash memory (step S 902 ). If absent, the state of such absence is informed to the user by the display unit  18  or by the speaker  6  (step S 903 ), and the sequence returns to the step S 901 . On the other hand, if the aforementioned step S 902  identifies the presence of the facsimile image received by memory reception, the CPU  1  displays, on the display unit  18 , a message such as “print *all, #search” in order to cause the user to select either the collective recording of all the facsimile images stored in the flash memory  13  or the selective recording of the desired facsimile image (step S 904 ). 
     If the collective recording is selected by the user through the operation  17  in the aforementioned step S 904 , the CPU  1  discriminates whether a facsimile image remains unrecorded (whether an unrecorded page exists) (step S 905 ). If all the facsimile images stored in the flash memory  13  have been recorded at least once, the absence of a new facsimile image is transmitted to the user through the display unit  18  or the speaker  6 . Subsequently, the fact that all the facsimile images are recorded is also transmitted through the display unit  18  or the speaker  6 , and all the facsimile images are recorded on the recording sheets by the recording unit  11  (step S 906 ). 
     After the recording operation, a questioning message whether all the recorded facsimile images ought to be erased is given through the display unit  18  to the user (step S 907 ). If the user selects the erasure by the operation unit  11 , the CPU  1  erases all the facsimile images (step S 908 ) and the presence sequence is terminated. In case the user does not select the erasure in the aforementioned step S 907 , the presence sequence is terminated without any process. 
     In case the aforementioned step S 905  identifies the presence of an unrecorded facsimile image (unrecorded page), the recording of such new facsimile image is displayed on the display unit  18  and such facsimile image alone is recorded. More specifically, at first the recording sheet sensor  15  discriminates whether the recording sheet is set (step S 909 ), and, if set, the facsimile image of a first page is recorded on the recording sheet (step S 910 ). Then the CPU  1  discriminates whether a succeeding page is present (step S 911 ), and, if absent, the sequence proceeds to the aforementioned step S 907 . Upon completion of the recording operation, the completion of the recording operation is informed to the user through the display unit  18  or the speaker  6 . In case the aforementioned step S 911  identifies the presence of a succeeding page, the CPU  1  discriminates whether the recording sheet is set (step S 913 ). 
     On the other hand, in case the aforementioned step S 909  identifies the absence of the recording sheet, a message requesting the setting of the recording sheet is given to the user through the display unit  18  or the speaker  6 , and the number of pages of the unrecorded facsimile image and the size (maximum size) thereof are also informed to the user by the display unit  18  (step S 912 ). The number of pages and the size of the unrecorded facsimile image are detected by the CPU  1 . 
     As soon as the recording sheet is set by the user and such setting is detected by the recording sheet sensor  15  (step S 913 ), the unrecorded facsimile image is recorded (step S 910 ). In case the step S 913  identifies that the recording sheet is not set, a message requesting the setting of the recording sheet is informed to the user by a display on the display unit  18  (step S 914 ). Then the CPU  1  discriminates whether a predetermined time T1 (for example, one minute) elapses after the display of such message requesting the setting of the recording sheet on the display unit  18  (step S 915 ), and, if not, the sequence returns to the step S 913 . Also, if the recording sheet is not set even after the lapse of the predetermined time T1 from the display of such requesting message, it is regarded as an error and the present sequence is terminated. In case of executing the recording operation again, the sequence is started from the beginning. Also in case the recording sheet is exhausted in the course of recording operation of the facsimile images, a message requesting the supplemental of the recording sheet is-given to the user by a display on the display unit  18 . 
     The unrecorded facsimile image as mentioned above includes a facsimile image not recorded over the entire page and a facsimile image not partially recorded on a page for some reason in the course of recording. 
     In case the user does not select the collective recording in the aforementioned step S 904 , the sequence is shifted to a search recording operation in which the user selects an image or images for recording among the received facsimile images, as will be explained in the following with reference to FIG.  10 . 
     If the step S 904  selects the search recording, the CPU  1  displays, on the display unit  18 , the number of receptions, date and time of reception of the facsimile images initially stored in the flash memory  13 , for example in a form of “1 case, 10/8 10:26” (step S 1001 ). If the first facsimile image is not desired by the user, the type of the key depressed by the user is discriminated (step S 1002 ). If the set key  17   r  or the FAX key  17   q  is depressed, the sequence proceeds to a step S 1008  to be explained later. If these keys are not depressed but the volume/selection key  17   i  is depressed, a search process is executed (step S 1003 ), and the facsimile image of a next case is displayed on the display unit  18  (step S 1004 ). In order to search a desired facsimile image among the plural images stored in the flash memory  13 , the volume/selection key  17   i  is depressed in succession until the desired facsimile image is displayed on the display unit  18  (steps S 1003  to S 1005 ). 
     When the facsimile image of the desired case is searched and the set key  17   r  or the FAX key  17   q  is depressed, the display unit  18  displays a message requesting the user to select whether the facsimile message of the desired case should be recorded or erased (step S 1007 ). If the user depresses the volume/selection key  17   i  without selecting the recording or the erasure, the display unit  18  displays the number of pages and the size of such facsimile image (step S 1009 ). Then, if the user further depresses the volume/selection key  17   i  (step S 1010 ), the display unit  18  displays the telephone number of the communication partner (step S 1011 ). This telephone number is transmitted by a TSI (transmission side identification) signal (a signal for sending a telephone number of a calling side to a called side) of the facsimile communication protocol. In case the telephone number has not been transmitted from the partner by such TSI signal, a message “not transmitted” is displayed on the display unit  18 . 
     The facsimile image of the desired case can be easily searched by the above-explained procedure. 
     If the volume/selection key  17   i  is depressed after the display of the telephone number in the step S 1010 , the sequence returns to the step S 1007 . 
     In case the volume/selection key  17   i  is not depressed in the aforementioned step S 1008 , the sequence proceeds to a process shown in FIG. 11, in which, in a step S 1101 , the CPU  1  discriminates whether the recording (print) is selected. If the recording is selected, the CPU  1  discriminates whether the facsimile image of the desired case contains plural pages (step S 1102 ). If the facsimile image of the desired case consists of a single page, such facsimile image is recorded (step S 1110 ) and the present sequence is terminated. If the step S 1102  identifies that the facsimile image of the desired case consists of plural pages, the user can designate the pages to be recorded among such plural pages. 
     The CPU  1  discriminates whether the user has designated the page to be recorded, and, if not, the sequence proceeds to the recording operation in the aforementioned step S 1110 . On the other hand, in case the page has been designated in the step S 1103 , the recording start page and the recording end page are entered through the operation unit  17  (step S 1104 ). Then the CPU  1  discriminates, in succession, whether the erasure key  17   i  is depressed (step S 1105 ), whether the function key  17   n  is depressed (step S 1106 ), whether the set key  17   r  or the FAX key  17   q  is depressed (step S 1107 ) and whether the page input contains an error (step S 1108 ). 
     If neither the erasure  17   j  nor the function key  17   n  is depressed, but the set key  17   r  or the FAX key  17   q  is depressed and the page input does not contain an error, the sequence proceeds to the recording operation in the step S 1110 . If the aforementioned step S 1107  identifies that the set key  17   r  or the FAX key  17   q  is depressed, the sequence returns to the step S 1105 . Also if the aforementioned step S 1108  identifies that the page input contains an error, an error sound is generated from the speaker  6  as a warning to the user when the set key  17   r  or the FAX key  17   q  is depressed (step S 1109 ) and the sequence then returns to the step S 1103 . 
     Also in case the aforementioned step S 1105  identifies that the erasure key  17   j  is depressed before the depression of the set key  17   r  or the FAX key  17   q  in the step S 1107  the sequence returns to the step S 1103 . Also in case the aforementioned step S 1106  identifies that the function key  17   n  is depressed before the depression of the set key  17   r  or the FAX key  17   q  in the step S 1107  the sequence returns to the step S 1001  in FIG.  10 . 
     In case the aforementioned step S 1101  selects the erasure, the sequence shifts to a process in FIG.  12 . More specifically, when the step S 1101  selects the erasure, the CPU  1  displays a message indicating the selection of the erasure on the display unit  18  (step S 1201 ). Then, the CPU  1  discriminates, in succession, whether the function key  17   n  is depressed (step S 1202 ) and whether the stop key  17   p  is depressed (step S 1203 ). If the step S 1202  identifies the depression of the function key  17   n , the sequence returns to the step S 1001  in FIG.  10 . If the step S 1203  identifies the depression of the stop key  17   p , the present sequence is terminated. 
     If the steps S 1202  and S 1203  identify that the function key  17   n  and the stop key  17   p  are not depressed, respectively, the CPU  1  displays, on the display unit  18 , a message requesting to confirm the user the erasure (step S 1204 ). If the user selects the erasure, the erasure is executed and a message such as “the erasure is completed” is displayed on the display unit  18  (step S 1206 ) and the sequence returns to the step S 1001  in FIG.  10 . On the other hand, if the confirmation for the erasure is not obtained in the step S 1204 , the CPU  1  discriminates the lapse of a predetermined time T2 (step S 1205 ). If the predetermined time T2 has not elapsed, the sequence returns to the step S 1202 . But, if the predetermined time T2 has elapsed, the present sequence is terminated. 
     The recording and erasure of the facsimile image received by memory reception are completed in this manner. 
     In the following there will be explained, with reference to FIGS. 13 and 14, the reproducing and erasing process for the message recorded in the message telephone unit  5 . 
     At first the CPU  1  discriminates whether the hold/message reproduction key  17   k  is depressed for reproducing the message recorded in the message telephone unit  5  (step S 1301 ). If depressed, the CPU  1  discriminates whether the recorded message is present (step S 1302 ). If present, all the messages and the recorded dates are reproduced (step S 1304 ), and the present sequence is then terminated. In case the step S 1302  identifies the absence of the recorded message, a message indicating the absence of the recorded message is given to the user by the speaker  6  or the display unit  18 , and the sequence returns to the step S 1301 . 
     In case the step S 1301  identifies that the hold/message reproduction key  17   k  is not depressed, the CPU  1  discriminates whether the message record/reproduction key  17   m  is depressed (step S 1305 ), and, if not, the sequence returns to the step S 1301 . Also in case the step S 1305  identifies the depression of the hold/message reproduction key  17   m , the CPU  1  discriminates whether the present apparatus is set at the message telephone mode (step S 1306 ), and, if not, the message telephone mode is set (step S 1310 ) and the sequence then returns to the step S 1301 . 
     On the other hand, if the aforementioned step S 1306  identifies that the present apparatus is set at the message telephone mode, the message telephone mode is released (step S 1307 ) and the CPU  1  discriminates whether the unreproduced message is present among the messages recorded in the flash memory  13  (step S 1308 ). If the unreproduced message is absent among the messages recorded in the flash memory  13 , the sequence returns to the step S 1301 . If the unreproduced message is present, the CPU  1  sets a pointer on such message (step S 1309 ) and the sequence proceeds to a process shown in FIG.  14 . 
     Referring to FIG. 14, the CPU  1  in a step S 1401  reproduces the message on which the pointer has been set, and, after the reproduction, a flag indicating the completion of reproduction is set (step S 1402 ). In the course of the reproduction, the CPU  1  discriminates whether the erasure key is depressed (step S 1403 ), and, if depressed, interrupts the reproduction of the message (step S 1404 ) and asks the user whether the message ought to be erased (step S 1405 ). If the message ought to be erased, the message of which reproduction is interrupted is erased (step S 1406 ). If the message ought not to be erased, the message is left in the flash memory  13  and the CPU  1  discriminates whether a next message is present (step S 1407 ). If the next message is present, the sequence returns to the aforementioned step S 1401 , but, if absent, the present sequence is terminated. 
     On the other hand, in case the step S 1403  identifies that the erasure key is not depressed, the CPU  1  discriminates whether the reproduction of the message is completed. If not, the sequence returns to the step S 1403 , but, if completed, the sequence proceeds to the step S 1407  in which the CPU  1  discriminates whether a next message is present. 
     In the above-explained configuration, the unreproduced message is reproduced in case the message record/reproduction key  17   m  is depressed while all the messages are reproduced in case the hold/message reproduction key  17   k  is depressed. But, it is also possible to reproduce the unreproduced message in response to the depression of the hold/message reproduction key  17   k  and to reproduce all the messages in response to the depression of the message record/reproduction key  17   m.    
     As explained in the foregoing, the reproduction of the messages can be achieved in two manners, so that it is possible to select the reproducing method such as collective reproduction of all the messages or selective reproduction of the unreproduced message only, according to the purpose of the user, and it is furthermore possible to cope with the error in the operation of the user. 
     In the foregoing, there have been explained the erasure process in the search of the facsimile image received by memory reception and the erasure process in the course of reproduction of the messages. In the following there will be explained, with reference to FIGS. 15A,  15 B and  16 , the collective erasure of the received facsimile image and the recorded message. 
     At first the state of use of the flash memory  13  is checked. In the same manner as the OGM transmission pattern varies according to the empty capacity of the flash memory  13 , the operation of the collective erasing mode of the flash memory  13  varies according to the empty capacity thereof. 
     At first, in a step S 1501  in FIG. 15A, the CPU  1  discriminates whether the erasure key  17   j  on the operation unit  17  is depressed. If the erasure key is depressed, the CPU  1  discriminates whether a message or a facsimile image is present in the flash memory  13  (S 1502 ). If the message or the facsimile image is absent in the flash memory  13 , the present sequence is terminated. If the step S 1502  identifies the presence of the message or the facsimile image in the flash memory  13 , the CPU  1  discriminates whether both the message and the facsimile image are present in the flash memory  13  (step S 1503 ). If both are present, a message requesting the selection of the erasure of either one is given to the user by a display on the display unit  18 , and, according to the key input by the user, whether the collective erasure mode for the messages or the collective erasure mode for the facsimile images is determined (step S 1504 ). If the collective message erasure mode is selected, the CPU  1  discriminates whether the collective message erasure mode has been selected consecutively throughout the serial operations of this sequence (step S 1505 ). Such consecutive selections have not been made in this stage since it is the first step in the serial operation. Then, confirmation is made to the user whether the messages ought to be collectively erased (step S 1506 ). On the display unit  18 , there is displayed a message requesting the confirmation that the messages ought to be collectively erased, and, in response to an input that the messages ought to be collectively erased, entered by the user through the operation unit  17 , the messages are collectively erased (step S 1507 ) and the sequence proceeds to a step S 1508 . On the other hand, if the user enters an input for canceling the collective erasure of the messages through the operation unit  17 , the collective message erasure mode is canceled and the sequence proceeds to a step S 1508 . If the messages are collectively erased, the display unit  18  displays a message indicating the completion of the collective erasure of the messages, for the user. 
     In the step S 1508 , the CPU  1  discriminates whether the facsimile image is present in the flash memory  13 , and, if not, the present sequence is terminated. If the step S 1508  identifies the presence of the facsimile image in the flash memory  13 , the sequence returns to the step S 1504 . 
     In case the user makes the same selection as in the foregoing step S 1505  in the serial operation of the collective message erasure mode, namely, for example, if the collective message erasure mode is selected again after the messages have been collectively erased, a message that the messages have already been collectively erased is given to the user by the display unit  18  or by the speaker  6  (step S 1509 ) and the sequence returns to the step S 1504 . 
     Also in case the collective erasure mode for the facsimile images is selected in the foregoing step S 1504 , there is executed a process similar to that of the collective message erasure mode explained above. More specifically, if the collective facsimile image erasure mode is selected in the step S 1504 , the CPU  1  discriminates whether the collective facsimile image erasure mode has been selected consecutively throughout the serial operations of this sequence (step S 1510 ). Such consecutive selections have not been made in this stage since it is the first step in the serial operations. Then confirmation is made to the user whether the facsimile images ought to be collectively erased (step S 1511 ). On the display unit  18 , there is displayed a message requesting the confirmation that the facsimile images ought to be collectively erased, and, in response to an input that the facsimile images ought to be collectively erased, entered by the user through the operation unit  17 , the facsimile images are collectively erased (step S 1512 ) and the sequence proceeds to a step S 1513 . On the other hand, if the user enters an input for canceling the collective erasure of the facsimile images through the operation unit  17 , the collective facsimile image erasure mode is canceled and the sequence proceeds to a step S 1513 . If the facsimile images are collectively erased, the display unit  18  displays a message indicating the completion of the collective erasure of the facsimile images. 
     In a step S 1513 , the CPU  1  discriminates whether the message is stored in the flash memory  13 , and, if not, the present sequence is terminated. If the step S 1513  identifies that the message is stored in the flash memory  13 , the sequence returns to the foregoing step S 1504 . 
     In case the user makes the same selection as in the foregoing step S 1510  in the serial operations of the collective facsimile image erasure mode, namely, for example, if the collective facsimile image erasure mode is again selected after the facsimile images have been collectively erased, a message that the facsimile images have already been collectively erased is given to the user by the display unit  18  or by the speaker  6  (step S 1514 ) and the sequence returns to the step S 1504 . 
     If the aforementioned step S 1502  identifies the absence of both the message and the facsimile image in the flash memory  13 , the present sequence is terminated. On the other hand, if the step S 1503  identifies that the flash memory  13  stores either the message or the facsimile image, there is assumed a collective erasure mode for the messages or the facsimile images and the sequence proceeds to a process shown in FIG.  16 . 
     In FIG. 16, the CPU  1  discriminates the message erasure mode or the facsimile image erasure mode (step S 1601 ), and, in case of the message erasure mode, a confirmation is made to the user whether the messages ought to be erased (step S 1602 ), and, if the messages ought to be erased, the messages are collectively erased (step S 1603 ) and the present sequence is terminated. On the other hand, if the step S 1602  identifies that the messages ought not to be erased, the collective message erasure mode is canceled and the present sequence is terminated. 
     In case the step S 1601  identifies that the message erasure mode is not selected, the CPU  1  discriminates whether the facsimile image erasure mode is selected (step S 1604 ), and, if selected, there is confirmed to the user whether the facsimile image ought to be erased (step S 1605 ). If the facsimile image ought to be erased, the facsimile images are collectively erased (step S 1603 ), and the present sequence is terminated. On the other hand, if the step S 1605  identifies that the facsimile images ought not to be erased, the collective facsimile image erasure mode is canceled and the present sequence is terminated. Also the present sequence is terminated in case the foregoing step S 1604  identifies that the facsimile image erasure mode is not selected. 
     If the messages or the facsimile images are collectively erased, a message indicating such erasure is displayed on the display unit  18 . 
     In the present invention, the state of use of the flash memory  13  is constantly monitored as explained in the foregoing, and such monitoring may be utilized for always informing the user of the state of use of the flash memory  13 . 
     In the following there will be explained, with reference to FIG. 17, a process of monitoring the state of use of the flash memory  13 . 
     There are determined, in advance, the number of the messages recordable in the flash memory  13  (assumed to be 20 cases in the present embodiment), the number of the facsimile images receivable by the memory reception (assumed to be 20 cases in the present embodiment), and the number of pages of such image (assumed to be 20 pages in the present embodiment). On the other hand, the physical capacity of the flash memory  13  is determined in advance (assumed to be 20 blocks in the present embodiment), regardless of the number of message recordings or the number of receptions of the facsimile images or the number of pages thereof (assumed to be 32 blocks in the present embodiment). 
     The CPU  1  monitors the remaining capacity of the flash memory  13  from four factors, namely the number of recordable messages, the number of receivable facsimile images, the number of receivable pages of the facsimile images and the number of remaining blocks of the flash memory  13 . 
     The CPU  1  discriminates, in succession, whether the number of recordable messages does not exceed 3 in a step S 1701  in FIG. 17, then whether the number of receivable facsimile images does not exceed 3 in a step S 1702 , whether the number of receivable facsimile image pages does not exceed 3 in a step S 1703 , and whether the number of remaining blocks of the flash memory  13  does not exceed 6 in a step S 1704 . In case the number of recordable messages does not exceed 3, in case the number of receivable facsimile images does not exceed 3, in case the number of receivable facsimile image pages does not exceed 3, or in case the number of remaining blocks of the flash memory  13  does not exceed 6, a warning message indicating a small remaining capacity of the flash memory  13  is given to the user either through the display unit  18  or the speaker  6  (step S 1706 ). 
     Then the CPU  1  discriminates whether the message or the facsimile image in the flash memory  13  has been erased (step S 1707 ), and, if erased, the sequence returns to the foregoing step S 1701 . If the message or the facsimile image has not been erased, the sequence returns to the step S 1706 . On the other hand, if the aforementioned step S 1704  identifies that the number of the remaining blocks of the flash memory  13  exceeds 6 blocks, the warning is not given to the user (step S 1705 ) and the present sequence is terminated. 
     In the following there will be explained, with reference to FIG. 18, a warning process by releasing messages according to the state of use of the flash memory  13 , in case the present apparatus is set at the message telephone mode. 
     In a step S 1801  in FIG. 18, the CPU  1  discriminates whether the message record/message setting key  17   m  is depressed for setting the present apparatus at the message telephone mode, and continues discrimination until such depression takes place. When the depression takes place, the CPU  1  discriminates whether the flash memory  13  is capable of recording the message (step S 1802 ). If the flash memory  13  is capable of recording the message, the CPU  1  discriminates whether at least four messages can be recorded (step S 1803 ). If at least four messages can be recorded, there is issued a first voice message, indicating that the message telephone mode has been set, to the user through the speaker  6  (step S 1805 ). 
     In case the aforementioned step S 1803  identifies that the number of recordable messages is less than 4, there is issued a second message to warn the user of a state that the capacity of the flash memory  13  soon becomes full and the unnecessary message or image should be erased (step S 1804 ). Also in case the aforementioned step S 1802  identifies that the message recording is not possible, there is issued a third warning message indicating that new message cannot be recorded and the unnecessary message or image should be erased. 
     After the issuance of the message to the user in the step S 1804 , S 1805  or S 1806 , the response message which is transmitted to the partner of communication in the message telephone mode is reproduced from the speaker  6 , then the message telephone mode is set (step S 1808 ), whereupon the present sequence is terminated. 
     Second Embodiment 
     In the following there will be explained, with reference to FIG. 21, a computer-readable memory medium to be employed in the image communication method and apparatus of the present invention. By reading the program stored in the memory medium, the computer executes the same processes as those of the first embodiment. In such operation, a printer, a facsimile apparatus and a modem are connected to the computer. The modem may be incorporated in an expansion board. Also a color copying is possible by connecting a scanner. The printer is equipped with a color cartridge or a monochromatic cartridge interchangeably. 
     The memory medium storing the program for controlling the image communication apparatus capable of color and monochromatic image recording stores certain program modules, including at least an “image reception module”, an “image storage module”, a “first detection module”, a first recording module”, a “second recording module”, a “second detection module” and a “control module” as shown in FIG.  21 . 
     The “image reception module” is used for receiving the image. The “image storage module” is used for storing the image. The “first detection module” is used for detecting which of the auto reception mode and the direct reception mode is set. The “first recording module” is used for monochromatic recording of the image with the color recording means. The “second recording module” is used for monochromatic recording of the image with the monochromatic recording means. The “second detection module” is used for detecting the presence/absence and the kind of the recording module supported on the support means. The “control module” is used for effecting the image receiving process according to the results of detection by the first detection module and the second detection module. 
     As explained in the foregoing, the first and second embodiments of the present invention allow to effect the memory reception in case the auto reception mode is selected, and to inform the partner of communication with a communication speed variably according to the kind of the recording means in case the direction reception mode is selected. More specifically, a high communication speed can be informed to the partner in case of employing recording means peculiar to monochromatic recording which can achieve faster recording than the recording means capable of color recording and but lessens the recording speed, whereby the image reception process can be achieved in securer manner and the error in reception can be avoided. 
     Also the memory medium of the second embodiment of the present invention allows to smoothly control the image communication apparatus of the present invention. 
     Furthermore, the first and second embodiments of the present invention allow to execute the memory reception in case the recording sheet is absent and to inform the partner of communication with a variable communication speed according to the kind of the recording means in case the recording sheet is present. More specifically, a faster communication speed can be informed to the partner in case of employing recording means peculiar to monochromatic recording which can achieve faster recording than the recording means capable of color recording but lessens in the recording speed, whereby the image reception process can be achieved in securer manner and the error in reception can be avoided.
