  The control unit 21 includes a RAM 21a that stores various data and an EEPROM (Electronically Erasable and Programmable Read Only Memory) 21b that is a ROM that can be written and erased.

  The wireless communication unit 27 transmits and receives various signals including audio signals to and from the child device 50 by wireless communication. The wireless communication unit 27 transmits an image transmission request to the child device 50 and is stored in the image data captured by the camera 58 of the child device 50, various signals when the image data cannot be transmitted, and the EEPROM 61b of the child device 50. The slave unit name data indicating the slave unit name is received. Here, the slave unit name is a name individually set for each slave unit 50. In this embodiment, the slave unit name can be set by inputting the slave unit name by operating the operation button 54. Yes, the set handset name is stored in a predetermined area of the EEPROM 61b. As the name of the child device, a name of a room in which the child device 50 is normally used, for example, names such as “living room” and “entrance” are set.

  When the handset 50 functions as a monitoring camera, the image data received by the wireless communication unit 27 from the handset 50 or various signals when the image data cannot be transmitted, and handset name data indicating the transmission source of the image data Based on the above, the control unit 21 displays the slave unit name and the image in association with each other on the monitor 16. When an image transmission request is transmitted to a plurality of slave units 50, the control unit 21 controls the screen 16 to divide the screen and display images based on replies from the slave units 50 for all image transmission requests. FIG. 4 is a screen display example of the monitor 16 when an image transmission request is transmitted to the four slave units 50. The screen is divided into four, and the slave unit names based on the slave unit name data transmitted from each of the four slave units 50 are displayed in the respective slave unit name display fields 101b, 102b, 103b, 104b. Indications indicating that images cannot be transmitted are displayed on the respective image display screens 101a, 102a, 103a, and 104a positioned below based on the contents of various signals transmitted when the corresponding images or image data cannot be transmitted. It is displayed.

  The route switching unit 31 is used for input / output of a voice signal that is transmitted / received to / from an external partner communication terminal via the telephone line network 100 when the operation for starting a call is performed. The transmission path to be switched is switched to either the handset 12 or the wireless communication unit 27 for communication with the handset 50. Specifically, when the handset 12 is removed from the main unit 10 main body, the transmission path is switched to the handset 12, and when the connection request signal to the telephone line network 100 transmitted from the sub unit 50 is received. The transmission path is switched to the wireless communication unit 27. When a command such as a dial signal of the other party is input via the user I / F 15, the NCU 29 connects to the telephone line network 100 and inputs / outputs various signals. In the base unit 10 configured as described above, when the power is turned on, the control unit 21 executes a process of transmitting a signal to the slave unit 50 in order to confirm the presence of the slave unit 50.

  Next, the slave unit 50 includes a control unit 61 that controls the operation of the slave unit 50 as a whole, a transmitter / receiver unit 63 that includes a speaker and a microphone and a drive circuit that drives them, a display panel 53, and a user I / O that includes operation buttons 54. F57, a camera 58 for capturing an image, a reproduction unit 65 that reproduces sound based on various audio signals stored in advance, a speaker 67 that outputs sound reproduced by the reproduction unit 65, and the wireless communication unit of the parent device 10 27) a wireless communication unit 69 that transmits and receives various signals including audio signals by wireless communication, a battery 71 that operates the slave unit 50 with charged power, and a remaining amount of power stored in the battery 71. Charge remaining power monitoring unit 73 for detection, charging terminal 55 for electrical connection with charging terminal 82 of charger 80, charging supplied from charger 80 via charging terminal 55 Various information is transmitted / received to / from the charging circuit 75 for charging the battery 71 with the power supply for power, the voltage monitoring unit 77 for detecting the voltage application to the charging terminal 55 via the charging circuit 75, and the data transfer terminal 83 of the charger 80. For this purpose, a data transfer terminal 56 connected is provided.

  The control unit 61 includes a RAM 61a for storing various data and an EEPROM 61b which is a ROM that can be written and erased.

  The EEPROM 61b stores a control program, an identification number for distinguishing it from other slave devices 50 that perform wireless communication with the same master device 10, and an operation button. It is detected that a charging voltage is applied to the terminal name for charging, the remaining power value for determining whether there is a required amount of the power name stored in the battery 71, and the remaining power value stored in the battery 71. Each condition such as a voltage judgment value is stored, and a storage area for storing information set by the user via the user I / F 57 is provided. The handset name is rewritten in a predetermined case, and the rewriting of the handset name will be described later.

  The wireless communication unit 69 transmits and receives various signals including audio signals to and from the parent device 10 by wireless communication. Further, in the present embodiment, when the slave unit 50 is set to function as a monitoring camera, the wireless communication unit 69 receives the image transmission request from the master unit 10, the image data captured by the camera 58, Alternatively, various signals when the image cannot be transmitted and the slave unit name data stored in the EEPROM 61b are transmitted to the master unit 10.

  The remaining power monitoring unit 73 measures the remaining power value stored in the battery 71 of the child device 50. If the remaining amount value measured by the remaining power monitoring unit 73 is less than the remaining power determination value stored in the EEPROM 61b, the control unit 61 determines that the charging amount of the slave unit 50 is insufficient. To do. When the amount of charge is insufficient, the call may be interrupted due to insufficient power, and the original function of the telephone is impaired. Therefore, if the controller 61 determines that the amount of charge is insufficient, it stops the imaging by the camera 58 to reduce power consumption, and prepares for charging as various signals instead of transmitting image data to the master unit 10. A signal indicating that “charging is insufficient” (corresponding to cause data) is transmitted.

  The voltage monitoring unit 77 measures the voltage applied to the charging terminal 55 in order to determine whether or not the child device 50 is placed on the charger 80 and is supplied with power. That is, when the charger 80 is connected to the commercial power supply 90 and receives power supply, and the handset 50 is mounted on the charger 80, the handset 50 is supplied with power via the charging terminal 55. Therefore, the voltage measured by the voltage monitoring unit 77 is equal to or higher than a predetermined value. However, when the handset 50 is not placed on the charger 80, power supply is not received, so the voltage measured by the voltage monitoring unit 77 is less than a predetermined value. In addition, even when the charger 80 is not connected to the commercial power supply 90 or the like and is not receiving power supply, the voltage measured by the voltage monitoring unit 77 is less than a predetermined value. Therefore, when the voltage measured by the voltage monitoring unit 77 is less than the voltage determination value stored in the EEPROM 61b, the control unit 61 determines whether the slave unit 50 is not placed on the charger 80 or supplies power. Judge that it has not received.

  If the handset 50 is not placed on the charger 80, it is meaningless to take an image, such as being left on the desk, and the power stored in the battery 71 when the image is continued. If the imaging is continued even when no power is supplied, the power stored in the battery 71 is consumed. If the power stored in the battery 71 is consumed without supplying power, the call may be interrupted due to insufficient power, and the original function of the telephone is impaired. Therefore, when the voltage measured by the voltage monitoring unit 77 is less than the voltage determination value, the control unit 61 stops imaging by the camera 58 and transmits various types of signals instead of transmitting image data to the parent device 10. A signal (corresponding to cause data) indicating that “charging is impossible” is transmitted.

  Even when the handset 50 is in a call, there is no point in capturing an image, and if the image capturing is continued, the power stored in the battery 71 may be consumed, and the call may be interrupted due to insufficient power. The original function of the telephone will be impaired. Therefore, even when the handset 50 is in a call, the control unit 61 stops imaging by the camera 58 and transmits a signal indicating “busy” as various signals instead of transmitting image data to the base unit 10. (Equivalent to cause data) is transmitted.

  The control unit 61 of the child device 50 configured as described above repeatedly executes the child device operation process shown in FIG. 5 when the child device 50 is powered on. In this slave unit operation process, in addition to the normal call process, the slave unit name update process, and when there is an image transmission request from the master unit 10, there is a menu display instruction from the user The menu selection process is executed.

  Next, the charger 80 is connected to transmit and receive various types of information between the charging terminal 82 for electrical connection with the charging terminal 55 of the slave unit 50 and the data transfer terminal 56 of the slave unit 50. A data transfer terminal 83 and an EEPROM 84 which is a ROM capable of writing and erasing are provided.

  When the handset 50 is placed on the charger main body 81 and the charging terminal 82 and the charging terminal 55 of the handset 50 come into contact with each other, the charger 80 receives direct power supply from the commercial power supply 90 and A charging voltage is supplied to the battery 71.

  Further, the slave unit 50 is placed on the charger main body 81, and when the data transfer terminal 56 of the slave unit 50 and the data transfer terminal 83 of the charger 80 are connected, various information is stored in the EEPROM 84 of the charger 80. For example, charger name data can be written and read.

  In the cordless telephone apparatus 1 configured as described above, the base unit 10 can make an external line call with an external partner communication terminal via the telephone line network 100 while being connected to the commercial power supply 90. . In addition, when power is turned on, the base unit 10 sends a confirmation signal to the handset 50 in order to check the state of the handset 50 (within the range where radio waves from the base unit 10 reach or is charged) and the number of handsets. An extension call can be made with the handset 50 that has transmitted and responded to the confirmation signal. When the child device 50 functions as a monitoring camera, the parent device 10 transmits an image transmission request to the child device 50 selected by the user, and transmits the image transmission request signal from the child device 50 that has received the image transmission request signal. The received image data and handset name data are received and converted into display data, and the image and handset name are associated with each other and displayed on the monitor 16.

  On the other hand, the handset 50 can make an outside line call with an external counterpart communication terminal via the base unit 10 and can also make an extension call with the base unit 10 or another handset 50. is there. In addition, the child device 50 can display a menu screen for selecting each function of the child device 50 on the display panel 53 when the user operates the operation button 54 (for example, a menu key). In this menu screen, a “phone number registration menu” for newly registering a telephone number for telephone directory data (not shown) stored in the EEPROM 61b, and a “volume adjustment menu” for changing the setting of the incoming call volume. In this embodiment, a “slave unit name setting menu” for setting a name in the slave unit 50 by inputting characters from the operation button 54 is displayed.

  Then, when the user performs an operation for selecting, for example, the “slave device name setting menu” from the operation button 54, the control unit 61 causes the display panel 53 to display a screen waiting for character string input, and prompts the user. To prompt input from the operation button 54. When the user finishes inputting the character string, the control unit 61 writes the input character string in the EEPROM 61b as slave unit name data.

  Further, a “charger name setting menu” for setting a name on the charger 80 can be displayed on the menu screen of the handset device 50 in the present embodiment, and the user can set the “charger name setting menu”. Is selected, the controller 61 writes the charger name input via the operation button 54 of the slave unit 50 as the charger name data into the EEPROM 84 of the charger 80 via the data transfer terminals 56 and 83. .

  As described above, in the present embodiment, the name of the handset 50 (for example, the installation location or the user name) is set as the handset name by the operation from the handset 50, and the handset name storage area (not shown) of the EEPROM 61b is set. Can be memorized). In addition, although the name can be set as the charger name for the charger 80 as well, the charger itself is not provided with a configuration for directly inputting the name. Is done. First, a charger name setting menu is selected, where a charger name is set by inputting characters from the operation button 54 of the slave unit 50, and temporarily stored in the RAM 61a. Next, by placing this handset 50 on, for example, the charger 80 for which a name is desired to be set, a command for transmitting the name via the data transfer terminals 56, 83, charger name data, etc. It is transmitted to the charger 80 side, and charger name data is stored in a charger name storage area (not shown) of the EEPROM 84. Here, the charger name stored in the charger 80 is not changed unless the charger name 80 is changed again by a menu operation from the slave unit 50.

  Next, rewriting of the slave unit name will be described.

  The handset 50 is placed on the charger 80 for charging when not in use. However, the handset 50 does not have a connection line and is moved freely, so that it is different from the charger 80 in the room in which the handset 50 was originally placed. May be placed on the charger 80 in the room. In that case, the image transmitted by the slave unit 50 is an image of a room in which the currently mounted charger 80 is installed. However, since the name of the room where the charger 80 that was initially placed is stored as the name of the child device, the child device 50 is stored in the parent device 10 together with the captured image data. When transmitted, the image displayed on the monitor 16 by the parent device 10 and its name (installation location) do not match. For example, there is a case where the name of the child device “living” is stored for a certain child device 50, and the child device 50 happens to be placed on the charger 80 installed at the entrance. In such a case, the slave unit 50 transmits the entrance image data to the master unit 10 and transmits “living” as the slave unit name data. Therefore, the master unit 10 sends the image of the entrance and the “living room” to the monitor 16. "Is displayed in association with the name. That is, the master unit 10 cannot correctly determine which installation location the received image data is based on the slave unit name of the source slave unit 50.

  On the other hand, since the charger 80 is not normally moved after being installed in each room, if the charger name, which is the name set in the charger 80, is transmitted together with the image, the master unit 10 receives it. It is possible to correctly determine which installation location the image data is and display it on the monitor 16. Therefore, in this embodiment, the charger name of the charger 80 on which the slave unit 50 is placed is transmitted together with the image data. Specifically, when the handset 50 is placed on the charger 80, the charging stored in the charger name storage area of the EEPROM 84 of the placed charger 80 via the data transfer terminal 56 is performed. The device name data is acquired, and a process of rewriting the slave device name stored in the slave device name storage area of its own EEPROM 61b with the acquired charger name is performed. As a result, the slave unit name of the slave unit 50 matches the charger name. In the above example, the slave unit name of the slave unit 50 stored as “living” is stored in the charger 80 at the entrance. As a result, the slave unit name is automatically updated to “entrance”, and when the slave unit 50 transmits image data of an image captured by the camera 58, the slave unit name “stored in the EEPROM 61 b“ "Entrance" is transmitted together as slave unit name data. As a result, the image displayed on the parent device 10 matches the name (installation location).

  Next, the procedure of the slave unit operation process executed by the control unit 61 of the slave unit 50 will be described with reference to the flowchart shown in FIG. FIG. 5 is a flowchart showing a slave unit operation process executed by the control unit 61 of the slave unit 50 according to the present embodiment. In addition, this subunit | mobile_unit operation | movement process is a process started repeatedly when the control part 61 starts with the electric power stored in the battery 71, and is repeatedly performed until there is no electric power.

  When the control unit 61 is activated, first, the presence / absence of an activation signal is determined (S1). Here, the activation signal is a call signal from the parent device 10 to the child device 50 (for example, a call when an incoming call from an external communication device is matched via the telephone line network 100), or from the child device 50 This is a transmission signal to the base unit 10. When the activation signal is not detected, that is, when neither the calling signal from the parent device 10 to the child device 50 nor the outgoing signal from the child device 50 to the parent device 10 is detected (S1: NO). The presence / absence of a wireless communication disconnection signal is determined (S2). Here, the wireless communication disconnection signal is a call end signal transmitted from the parent device 10 to the child device 50 or a call end signal transmitted from the child device 50 to the parent device 10.

  When the wireless communication disconnection signal is not detected, that is, when neither of the call end signals is detected (S2: NO), it is determined whether there is an image transmission request from the parent device 10 (S3). When an image transmission request is not detected (S3: NO), it is determined whether there is a menu display instruction (S4). A menu display instruction is input from the operation button 54 of the child device 50. When the menu display instruction is not detected (S4: NO), the slave unit name update process is performed (S5), the process returns to Step S1, and Steps S1 to S5 are repeated thereafter. The slave unit name update process will be described later.

  When an activation signal is detected, that is, when a calling signal from the parent device 10 to the child device 50 is detected, or when a transmission signal from the child device 50 to the parent device 10 is detected (S1: YES). ), The master unit 10 and the slave unit 50 are connected via wireless communication (S6), and the process returns to step S1. By this connection, the handset 50 can perform an extension call with the base unit 10 and an external line call via the base unit 10. The slave unit operation process is repeatedly executed even during a period in which the extension call or the outside line call is performed. Subsequently, when the wireless communication disconnection signal is detected, that is, when one of the call end signals is detected (S2: YES), the connection between the parent device 10 and the child device 50 via the wireless communication is disconnected. (S7), the process returns to step S1.

  If an image transmission request is detected (S3: YES), transmission processing is performed (S8), and the process returns to step S1. This transmission process will be described later. If a menu display instruction is detected (S4: YES), menu selection processing is started (S9), and the process returns to step S1. The menu selection process is executed in parallel with the slave unit operation process, and the slave unit operation process is continued. Therefore, even when the menu selection process is being executed, it is possible to detect the activation signal from the parent device 10.

  In this menu selection process, as described above, the slave unit menu screen is displayed on the display panel 53 of the slave unit 50. When the user selects various menus by operating the operation buttons 54, processing of the selected menu is executed. In the slave unit selection menu, as described above, the “slave unit name setting menu” for setting the slave unit name in the slave unit 50 and the charger name in the charger 80 on which the slave unit 50 is placed are set. "Charger name setting menu" is included.

  FIG. 6 is a flowchart showing the slave unit name update process. By this processing, the slave unit name of the slave unit 50 always matches the charger name of the installed charger 80.

  First, it is determined whether or not the child device 50 is placed on the charger 80 (S11). This determination is made based on whether or not the data transfer terminal 56 of the slave unit 50 is connected to the data transfer terminal 82 of the charger 80. Even if the handset 50 is not supplied with power from the charger 80, when receiving an image transmission request from the base unit 10, the handset name is returned, so the handset name is updated with the name of the charger. There is a need. Therefore, the determination based on the voltage measured by the voltage monitoring unit 77 that is determined not to be mounted even when the slave unit 50 is mounted on the charger 80 but not receiving power supply is inappropriate. .

  When it is determined that the handset 50 is placed on the charger 80 (S11: YES), the charger name is read from the EEPROM 84 of the charger 80 (S12), and the charger name is set. It is determined whether or not there is (S13). When the charger name is set (S13: YES), the charger name read from the EEPROM 84 of the charger 80 is compared with the slave unit name read from the EEPROM 61b of the slave unit 50 (S14). ), It is determined whether the charger name and the slave unit name are the same (S15). When the charger name and the slave unit name are different (S15: NO), the slave unit name in the EEPROM 61b is rewritten with the charger name in the EEPROM 84 (S16), and the slave unit name update process is terminated. If the charger name is set (S13: YES), the comparison of the charger name and the slave unit name in steps S14 and S15 is performed, and the slave unit name is rewritten with the charger name. Good.

  If the charger name and the slave unit name are the same (S15: YES), the slave unit name is not rewritten, and the slave unit name update process is terminated. When the charger name is not set (S13: NO), the display panel 53 displays “No charger name is set for the charger” (S17). The data is rewritten to character string data indicating "None" (S18), and the slave unit name update process is terminated. If it is determined that the child device 50 is not placed on the charger 80 (S11: NO), the child device name cannot be updated, and the child device name update process is terminated.

  FIG. 7 is a flowchart showing the transmission process. This process is a process executed by the control unit 61 of the slave unit 50 in order to send a reply when there is an image transmission request from the master unit 10.

  First, it is determined whether or not the child device 50 is placed on the charger 80 and is supplied with power (S21). This determination is made based on the voltage measured by the voltage monitoring unit 77. That is, when the voltage is equal to or higher than the voltage determination value stored in the EEPROM 61b, it is determined that the handset 50 is placed on the charger 80 and is supplied with power, and is less than the voltage determination value. In some cases, it is determined that the handset 50 is not placed on the charger 80 or is not receiving power supply.

  When it is determined that the child device 50 is placed on the charger 80 and is supplied with power (S21: YES), it is determined whether or not the charge amount of the child device 50 is sufficient (S21: YES). S22). This determination is made on the basis of the remaining power value stored in the battery 71 of the slave unit 50 measured by the remaining power monitoring unit 73. That is, when the remaining power value measured by the remaining power monitoring unit 73 is equal to or larger than the remaining power determination value stored in the EEPROM 61b, it is determined that the charging amount of the slave unit 50 is sufficient, and the remaining power is determined. When it is less than the amount determination value, it is determined that the charging amount of the slave unit 50 is insufficient.

  When it is determined that the charging amount of the slave unit 50 is sufficient (S22: YES), an image of the installation location is taken by the camera 58 (S23), and the image data and the slave unit name data are stored in the master unit 10. The transmission process is terminated (S24). Specifically, the captured image data is temporarily stored in the RAM 61a of the slave unit 50. The accumulated image data and the slave device name data stored in the EEPROM 61b are transmitted from the wireless communication unit 69 to the master device 10 by wireless communication.

  When it is determined that the charging amount of the slave unit 50 is insufficient (S22: NO), the camera 58 does not perform imaging, and a signal indicating that “charge is insufficient” and the slave unit name data are 10 (S25), and the transmission process is terminated.

  When it is determined that the handset 50 is not placed on the charger 80 or not supplied with power (S21: NO), it is determined whether the handset 50 is in a call (S26). When a call is in progress (S26: YES), the camera 58 does not capture an image, but a signal indicating "busy" and the slave unit name data are transmitted to the master unit 10 (S27), and the transmission process ends. Is done. When the telephone call is not in progress (S26: NO), the handset 50 is left without being placed on the charger 80, or the placed charger 80 is not connected to the commercial power source 90, or a failure occurs. The power supply is not being received. Therefore, in this case as well, imaging by the camera 58 is not performed, and a signal indicating that “charging is not possible” and the slave unit name data are transmitted to the master unit 10 (S28), and the transmission process is terminated.

  Next, the procedure of the master unit operation process executed by the control unit 21 of the master unit 10 will be described with reference to the flowchart shown in FIG. FIG. 8 is a flowchart showing a base unit operation process executed by the control unit 21 of the base unit 10 according to the present embodiment. Note that this base unit operation process is a process that is started when the base unit 10 is connected to the commercial power supply 90 and receives power supply and the control unit 21 is activated, and is repeatedly executed until no power supply is received.

  When the control unit 21 is activated, it is first determined whether or not there is an activation signal (S31). Here, the activation signal is a transmission signal from the parent device 10 to the child device 50 or a call signal from the child device 50 to the parent device 10. When the activation signal is not detected, that is, when neither the transmission signal from the parent device 10 to the child device 50 nor the calling signal from the child device 50 to the parent device 10 is detected (S31: NO). The presence / absence of a wireless communication disconnection signal is determined (S32). Here, the wireless communication disconnection signal is a call end signal transmitted from the parent device 10 to the child device 50 or a call end signal transmitted from the child device 50 to the parent device 10.

  When no wireless communication disconnection signal is detected, that is, when neither call end signal is detected (S32: NO), the presence / absence of a line connection signal is determined (S33). Here, the line connection signal is an outgoing call signal transmitted from the base unit 10 to the telephone communication network 100 and an incoming call signal transmitted from the telephone communication network 100 to the base unit 10. When the line connection signal is not detected, that is, both the call signal transmitted from the base unit 10 to the telephone communication network 100 and the incoming call signal transmitted from the telephone communication network 100 to the base unit 10 are detected. If not (S33: NO), the presence / absence of a line disconnection signal is determined (S34). Here, the line disconnection signal is a call end signal transmitted from the base unit 10 to the telephone communication network 100 and a call end signal transmitted from the telephone communication network 100 to the base unit 10.

  When the line disconnection signal is not detected, that is, when neither call end signal is detected (S34: NO), the presence / absence of a menu display instruction is determined (S35). A menu display instruction is input from the operation button 14 of the parent device 10. When the menu display instruction is not detected (S35: NO), image display processing is performed (S36), the process returns to step S31, and thereafter, steps S31 to S36 are repeated. The image display process will be described later.

  When an activation signal is detected, that is, when a transmission signal from the parent device 10 to the child device 50 is detected, or when a call signal from the child device 50 to the parent device 10 is detected (S31: YES). ), Base unit 10 and handset 50 are connected via wireless communication (S37), and the process returns to step S31. With this connection, the parent device 10 can make an extension call with the child device 50. When the wireless communication disconnection signal is detected, that is, when one of the call end signals is detected (S32: YES), the connection between the parent device 10 and the child device 50 via the wireless communication is disconnected (S38). ), The process returns to step S31.

  When a line connection signal is detected, that is, when a call signal transmitted from the base unit 10 to the telephone communication network 100 is detected, or when an incoming call signal transmitted from the telephone communication network 100 to the base unit 10 is detected. If detected (S33: YES), base unit 10 is connected to telephone communication network 100 (S39), and the process returns to step S31. With this connection, base unit 10 can make an outside line call via telephone communication network 100. When a line disconnection signal is detected, that is, when one of the call end signals is detected (S34: YES), the connection of the base unit 10 to the telephone communication network 100 is disconnected (S40), and the process goes to step S31. Return.

  If a menu display instruction is detected (S35: YES), menu selection processing is started (S41), and the process returns to step S31. The menu selection process is executed in parallel with the parent machine operation process, and the parent machine operation process is continued. Accordingly, it is possible to detect an incoming signal from the telephone line network 100 even during execution of the menu selection process.

  In the menu selection process, a master menu screen is displayed on the display panel 13 of the master 10. When the user selects a desired menu by operating the operation buttons 14 on this screen, processing of the selected menu is executed. In this menu screen, for example, a new telephone number is registered with respect to telephone directory data (not shown) stored in the EEPOM 21b, and details regarding the telephone / fax function such as setting of a ring tone or a holding tone are provided. In addition to being able to make settings, in the present embodiment, a “slave unit selection menu” for setting when the slave unit 50 functions as a monitoring camera (slave unit camera mode) is displayed.

  When the “slave unit selection menu” is selected, the control unit 21 of the base unit 10 sends a confirmation signal to each slave unit 50 and receives a response signal thereto, whereby each slave unit 50 is operating. And the identification number and slave unit name of the slave unit 50 in operation are displayed on the display panel 13. Here, the identification number of the slave unit 50 selected by the user by operating the operation button 14 is stored in the RAM 21a. The control unit 21 makes a transmission request for the captured image data to the selected slave unit 50 stored in the RAM 21a. In addition, control is performed to divide the screen of the monitor 16 in accordance with the number of selected handset 50, and an image based on the image data returned in response to the transmission request is displayed on each screen (FIG. 4).

  In some cases, the active child device 50 includes two or more child devices 50 having the same child device name. For example, the slave unit 1 that has been placed on the charger “A” but is not currently placed on any charger and is left unattended, and the slave unit 2 that is currently placed on the charger “A” are: In both cases, the name of the handset becomes “A”. At this time, in “child device selection”, two child devices “A” are displayed on the display panel 13, and even if the user selects both child devices “A”, they are placed on the charger “A”. The other handset 1 does not perform imaging by the camera 58 (see step S28 in FIG. 7), and performs imaging for the first time when placed on any charger.

  FIG. 9 is a flowchart showing image display processing. This process is a process of displaying an image on the monitor 16.

  First, it is determined whether or not “child device camera mode” for causing the child device 50 to function as a monitoring camera is set to ON (S50). This mode setting may be configured such that, for example, one button among the operation buttons 14 is assigned and set by pressing the button, or set to ON from the menu screen of the parent device 10. The setting contents are stored in a predetermined area of the RAM 21a. If it is not set to ON (S50: NO), the image display process is terminated. If it is set to ON (S50: YES), whether an image transmission request has been transmitted to all the slave units 50 that are selected to display images on the monitor 16 in the “slave unit selection menu”. It is determined whether or not (S51). The handset 50 displayed on the monitor 16 is selected by the “handset selection menu” and stored in the RAM 21a. When an image transmission request is issued to all selected slave devices 50 (S51: YES), the image display process is terminated. If there is a slave unit 50 that has not yet requested an image transmission (S51: NO), an image transmission request is transmitted to the slave unit 50 (S52).

  Next, it is determined whether or not a reply from the slave unit 50 that has requested the image transmission has been received (S53). If no reply is received (S53: NO), the process returns to step S53. That is, it waits until a reply is received from the handset 50 that has requested the image transmission. If the predetermined time has elapsed, it is determined that the handset 50 is out of order or is in a state where wireless communication is not possible, for example, so that it is not possible to send a reply. "Is displayed (S54).

  When a reply is received (S53: YES), an image based on the reply from the slave unit 50 is displayed on the monitor (S54), and the process returns to step S50. Specifically, when there is a reply from the slave unit 50 and the contents are captured image data and slave unit name data, the image and the slave unit name are displayed on the monitor 16 (the upper right image in FIG. 4). Refer to the lower left image). When a signal indicating that “charge is insufficient” and the slave unit name data are transmitted from the slave unit 50, a character string “slow battery level” and the slave unit name are displayed on the monitor 16 (FIG. 4). When a signal indicating “busy” and the slave device name data are transmitted from the slave device 50, the character string “speaking” and the slave device name are displayed on the monitor 16 (FIG. 4). (See upper left image). If the cordless handset 50 signal and the cordless handset name data are sent from the cordless handset 50, “The cordless handset is not set in the charger or the charger outlet is disconnected. "And the name of the slave unit are displayed on the monitor 16.

  In the above embodiment, the name is stored in the EEPROM of the slave unit and the charger. However, the identification number is set in the charger, and for example, as shown in FIG. A table of charger names may be set, and the identification number of the charger on which the slave unit is placed may be transmitted together with the image. In this case, the parent device may refer to the charger name from the table based on the charger identification number transmitted by the child device, and display the image and the charger name in association with each other on the monitor.

  In the above-described embodiment, the slave unit determines its own call state. However, the master unit may determine the call state of each slave unit. In this case, since the parent device can determine the call state of the child device without waiting for a reply from the child device, the image of the child device is transmitted without transmitting an image transmission request to the child device during the call. The character string “During a call” may be displayed on the monitor. In addition, the charging state and placement state of each child device and the child device name may be periodically transmitted to the parent device so that the parent device can perform centralized management. In this case, the parent device only needs to receive the image of the child device that can be displayed, and only needs to transmit an image transmission request to the child device.

  Moreover, although the said embodiment demonstrated the case where the control part of a subunit | mobile_unit performed writing and reading of the charger name to EEPROM of a charger, the control part was provided in the charger and the instruction | command of the control part of a subunit | mobile_unit was carried out. Accordingly, the controller of the charger may perform writing to and reading from the EEPROM.

  Furthermore, in the above embodiment, assuming that the slave unit moves to another installation location and the image transmitted from the slave unit does not match the slave unit name, the charger has a low possibility of movement. The name that can identify the installation location is memorized, and the slave unit is placed on the charger, so that the slave unit acquires the location of the slave unit from the charger as the slave unit name, and the slave unit's own slave unit name is stored. However, it is not always necessary to set a name for the charger if the usage is very unlikely to be moved. The name may be set and stored, and the slave unit name data and the captured image data may be always transmitted to the master unit. In that case, S5 (the process of FIG. 6) in the flowchart of FIG. 5 can be omitted.

  In that case, the name of the slave unit is not necessarily set from the operation button of the slave unit and need not be stored in the slave unit itself. The slave unit stores only identification information for identifying each slave unit. Alternatively, the parent device may be configured to manage the identification information of the child device and the name of the child device in association with each other.
