[Third embodiment]
  FIG. 17 is a diagram for explaining a connection relationship between the facsimile apparatus main body (master unit) 20 and the slave units 120A and 120B according to the third embodiment. In the third embodiment, as in the first embodiment, the facsimile apparatus main body (master unit) 20 is connected to the L mode gateway 16 via the public telephone line 15 and an exchange (not shown), and information retrieval on the L mode is performed. It is possible. There are two types of slave devices, a slave device 120A capable of displaying only text-based images and a slave device 120B capable of displaying images and text-based data. When the search information transfer is requested from the slave unit 120A that can display only the text-based image, the base unit 20 transmits the text-based image data and can display the image and the text-based image. When transfer of search information is requested from the slave unit 120B, an image and text-based image data are transmitted.
[0057]
  For this reason, in the third embodiment, information acquired from the L mode gateway 16 (server) can be browsed even by the slave unit 120A that cannot display image base data. On the other hand, text and image base data are transmitted to the slave unit 120B capable of displaying image base data. For this reason, it becomes possible to comfortably browse the full image of the text and image base data acquired from the L mode gateway 16.
[0058]
  Further, in the third embodiment, the slave unit 120B capable of displaying image base data can be configured to select either image base data or text base data as an image to be displayed on the display 21 by setting. Has been. For this reason, a user's request for a fast image transfer speed and a user's request for a full image transfer can be satisfied.
[0059]
  Next, processing on the base unit 20 side of the third embodiment will be described.
  The CPU 57 first determines whether or not the key (L button) 22b for starting communication with the L mode gateway 16 has been operated (S12). When the L button 22b is operated (S12: Yes), Communication with the L mode gateway 16 in the parent device 20, that is, a GW communication process for the parent device for performing a simple Internet search is performed (S100). On the other hand, unless the L button 22b is operated (S12: No), it is determined whether or not the slave unit 120 is operated and a GW communication start slave unit command for starting L mode gateway communication is transmitted from the slave unit side (S14). ). Here, when the GW communication start slave device command is received (S14: Yes), the slave device 120 performs a slave device GW communication process for performing a simple Internet search (S200). Then, unless a GW communication start slave device command is received (S14: No), the process is terminated.
[0060]
  The master unit GW communication process (S100) of the third embodiment is the same as that of the first embodiment described above with reference to FIG. 8, and thus illustration and description thereof are omitted, and the slave unit GW communication process (S200). Will be described with reference to FIGS. 19 and 20.
  First, the CPU 57 determines whether or not the image base data of the slave unit requested to acquire data can be displayed, that is, whether or not the slave unit 120B (S306). When the image base data can be displayed (S306: Yes), it is determined whether a text base request is made from the slave unit 120B (S308). Here, when the slave unit that has requested data acquisition cannot display the image base data (S306: No), or the image base data can be displayed but the text base image data from the slave unit 120B. Is made (S308: No), the process proceeds to S210 shown in FIG. The processing of S210 to S242 in FIG. 20 is the same as the procedure described above with reference to FIG. 8 in which the text-based image is displayed on the handset side of the first embodiment, and thus description thereof is omitted.
[0061]
  On the other hand, if a request for image-based image data is made in the slave unit 120B that can display image-based data (S308: Yes), the process proceeds to S310 and acquisition of the image data corresponding to the command is completed. Determine whether or not. When the acquisition of the image data is completed (S310: Yes), the HTML file constituting the image data is interpreted, and new image data for displaying the image and the external device of the text-based slave unit 120B is created (S312). New image data is transmitted to the slave unit (S313). Thereby, an image and a text-based image are displayed on the display device 121 of the slave unit 120B.
[0062]
  And it waits until the command corresponding to the key input of the subunit | mobile_unit 120B is received (S314). If a command is received (S314: Yes), after converting the received command into a GW communication command (S316), it is determined whether or not the command is sent to the L-mode gateway (GW) (S318). If the command is to be sent to the GW (S318: Yes), the command is sent to the GW (S320).
[0063]
  On the other hand, if the command is not to be sent to the GW (S318: No), it is determined whether or not the command is an instruction to end the GW communication, that is, to end the simple Internet search (S330). If it is not an instruction to end the GW communication (S330: No), image data corresponding to the command is created and transmitted to the slave unit (S332). Processing according to the command is performed (S334). Then, the process returns to S310 and continues.
[0064]
  On the other hand, when the end of the GW communication is instructed (S330: Yes), after the end of the GW communication such as closing the line with the L mode gateway (S340), the image of the display 121 of the slave unit After transmitting a command to display the standby state to the slave unit (S342), all the processes are terminated.
[0065]
  Next, processing executed by CPU 157 of slave unit 120A and slave unit 120B will be described. FIG. 21 is a flowchart showing a flow of main control processing executed by the CPU 157 of the slave unit 120A capable of displaying only text-based images in the third embodiment, and FIG. 22 is a child capable of displaying image-based data. It is a flowchart which shows the process in the machine 120B. Here, the process in the slave unit 120A that can display only the text-based image shown in FIG. 21 is the same as the process in the slave unit 120 of the first embodiment with reference to FIG. Processing in slave unit 120B capable of displaying image base data will be described with reference to FIG.
[0066]
  The CPU 157 stands by until a key input is made (S412). If there is a key input (S412: Yes), it is determined whether or not the key specifies transfer data (S413). Here, when the text-based image display is designated by the user and when the image base data is designated (S413: Yes), a command designated by the transfer data is transmitted to the parent device side ( S415).
[0067]
  If the key is not designated as transfer data (S413: No), it is determined whether or not a key for starting L-mode gateway communication (GW communication), that is, a key for performing a simple Internet search is input. If it is determined (S414) and it is not the start key (S414: No), processing other than L-mode gateway communication is performed (S420). On the other hand, when the start key is operated (S414: Yes), a command for starting the L mode gateway communication is transmitted to the parent device 20 (S430). Correspondingly, when new image data is created and sent from the base unit side (S432: Yes), the received image and text-based image or text-based image are displayed on the display 121. To display. Since the subsequent processes in S440 to S450 are the same as those in the first embodiment described above, the description thereof is omitted.

[0069]
  In the fourth embodiment, the base unit 20 acquires text data and at least any one of a still image, a moving image, and audio from the L mode gateway 16 via the public telephone line 15. Then, when transmitting the acquired data from the parent device 20 to the PDA 220 via the child device 120, the type of data that can be expanded on the child device 20 side is identified, and only data that can be expanded on the child device side is transmitted. For this reason, on the side of the slave unit, it is possible to properly browse the expandable data among the data acquired from the L mode gateway 16 (server).
[0070]
  The main processing (the master unit GW communication process of S12 and S100, the slave unit GW communication process of S14 and S200) in the CPU 57 on the base unit 20 side of the fourth embodiment is the same as that described above with reference to FIG. Since the master unit GW communication process in S100 during the main process is the same as that in the first embodiment, the slave unit GW communication process in S200 is shown in FIGS.

Therefore, the process of transmitting data in S500 to the slave unit 120 will be described with reference to FIG. 25 showing a subroutine of the process.
[0072]
  In the subroutine, first, the type of data that can be processed by the slave unit 120 is identified (S510). Then, it is determined whether there is untransferred data (S512). If there is untransferred data (S512: Yes), it is determined whether the untransferred data is a text-based image (S514). In the case of a base image (S514: Yes), the text-based image is transferred to the handset side (S516). Further, it is determined whether or not the untransferred data is an image-based image (S524). If the untransferred data is image-based (S524: Yes), the image base data is transferred to the slave unit (S526). If the untransferred data is a moving image, based on the identification in S510, it is determined whether or not it can be displayed on the slave unit side, that is, on the PDA 220 connected to the slave unit (S534). (S534: Yes), the moving image is transferred to the slave unit (S536). Further, when the untransferred data is voice, it is determined whether or not the data can be output from the slave device side, that is, the PDA 220 connected to the slave device (S538). If the data can be output (S538: Yes), The voice data is transferred to the handset side (S540).
[0073]
  Processing on the handset side of the fourth embodiment will be described with reference to FIG. Since the slave unit side processing of the fourth embodiment is the same as that of the second embodiment described above with reference to FIG. 16 except for the processing in S424, only the processing in S424 will be described. In S424, a command for identifying the external device (PDA) that detected the connection is transmitted to the parent device 20. Thereby, the master unit 20 identifies the type of data that can be processed by the slave unit 120 (S510), and identifies the type of data that can be processed by the external device (PDA) and the slave unit 120 as described above (S512). ), Only processable data is transferred (S514 to S540).
