Hereinafter, it demonstrates in order.

[1] Procedure from Start to End of Call Using Wireless Handset 50 In FIG. 4, the wireless handset 50 is initially placed on the base unit 30. In this state, the placement detection unit 38 of the base unit 30 detects that the wireless slave unit 50 is placed, and the detection signal is sent to the base unit control unit 31, and the base unit control unit 31 In response to the detection signal, the wireless slave device 50 is controlled to supply power.

  When the user of the wireless slave device 50 picks up the wireless slave device 50 from the placement unit of the master device 30 (operation P1), the wireless slave device 50 is lifted from the master device 30 in the state detection unit 54 of the wireless slave device 50. Detect that. When the wireless slave device controller 51 of the wireless slave device 50 detects that the wireless slave device 50 has been picked up from the master device 30 based on the output from the state detector 54, the wireless slave device control unit 51 wirelessly communicates with the wireless slave device 30 via the wireless line. Communication with the interface unit 33 is performed, and the detection of being picked up is determined to be off-hook, and an off-hook notification is transmitted to the parent device 30. In base unit 30, when receiving the off-hook notification from wireless handset 50, base unit control unit 31 notifies extension interface unit 13 of main apparatus 1 via extension line 2 from extension interface unit 32. The off-hook notification is detected by the control unit 11 and is called from the external line interface unit 12 to the telephone line 4. When this call reaches an exchange not shown, a dial tone is returned and sent from the main unit 1 to the wireless slave unit 50 via the master unit 30, and the dial tone is received by the voice processor 53 (not shown). ) Is output.

  Next, when the user of the wireless slave device 50 performs a dial operation (operation P2) using the operation unit 57, a dial signal is transmitted to the master device 30 via the wireless line, and the extension interface 32 and It is sent to the main apparatus 1 via the extension line 2 and dialed from the main apparatus 1 to the telephone line 4. Until the other party answers, a ringback tone is returned from the exchange, and is output from the handset of the wireless handset 50 in the same manner as the dial tone. When there is a response (operation P3) from the other party of the transmission destination, a response signal is returned, and a telephone call (operation P4) can be performed between the wireless slave device 50 and the transmission destination.

  Next, the user who has made a call using the wireless slave device 50 ends the call and places the wireless slave device 50 on the parent device 30 (operation P5). In the base unit 30, when the wireless slave unit 50 is placed, the placement detection unit 38 generates a detection signal and notifies the base unit control unit 31 of the detection signal. When the wireless slave device control unit 51 of the wireless slave device 50 detects that it is placed on the parent device 30 based on the output signal from the state detection unit 56, the detection of the placement is regarded as on-hook. , Notify base unit 30. This on-hook notification is sent from the master unit 30 to the main device 1. When receiving the on-hook notification, the main apparatus 1 controls the external line interface unit 12, the exchange processing unit 14, and the internal line interface unit 13 to disconnect the line. In addition, when the end key of the wireless slave device 50 is pressed when the call is ended, the on-hook is similarly notified and the line is disconnected.

[2] When the wireless slave device 50 is picked up from the placement unit 30-a of the master device 30 or the flash key of the master device 30 is operated (FIG. 5)
As a premise for performing the processing of this figure, when the wireless slave device 50 is picked up from the placement unit 30-a of the master device 30, the speaker, not the handset of the wireless slave device 50, is in a receiving state, and a dial tone is output. It is assumed that the button telephone apparatus of FIG.

  The control unit 11 of the main device 1 first determines whether or not any operation has been performed in the master unit 30 or the wireless slave unit 50 (step S1). If it is determined that the operation has been performed, then the operation is performed next. It is determined whether or not the wireless slave device 50 is off-hook (step S2). If it is determined that the wireless slave device 50 is off-hook, control is performed so that the dial tone is output with the speaker of the wireless slave device 50 being in a receiving state (step S3), and the process is terminated.

  If it is determined in step S2 that the wireless slave device 50 is not off-hook, it is determined whether or not the flash key is pressed on the master device 30 (step S4). It is determined whether or not the device 50 is busy on an outside line (step S5). If the wireless handset 50 determines that an external line call is in progress, the wireless handset 50 disconnects the line on which the call is being made, re-acquires the line, places the handset of the wireless handset 50 into a call state, and dials tone from the handset. (Step S6). Here, it is assumed that the external telephone call of the wireless slave device 50 is performed by the handset, not the speaker.

  If it is determined in step S4 that the flash key of the parent device 30 has not been pressed, and if it is determined in step S5 that the wireless slave device 50 is not in an external line call, other processing is performed (step S7). ).

  As described above, when the wireless slave unit 50 is picked up from the placement unit 30-a of the master unit 30, a dial tone is output from the speaker of the wireless slave unit 50 so that the dial tone can be output without having to touch the receiver. Since the dial tone is output from the handset of the wireless slave device 50 when the flash device is operated on the master device 30 during a call by the wireless slave device 50, the operability is improved. In step S4, the same processing is performed when the call is terminated and the external line key is operated immediately to capture the external line instead of the flash operation (operation for recapturing the same external line as once released). The outside line to be captured in this case may be the same as or different from the released outside line. That is, step S4 is performed in the same manner for the outside line capturing operation (operation for once releasing the outside line and capturing the same or different outside line again).

[3] When the external line capture key or flash key of the master unit 30 is operated without the wireless slave unit 50 being placed on the master unit 30 (FIG. 6)
As a premise for performing the processing of this figure, when the external device is captured by the master device 30 when the wireless slave device 50 is not placed on the master device 30, the speaker of the master device 30 is in a receiving state and a dial tone is output. It is assumed that the button telephone apparatus of FIG.

  The control unit 11 of the main device 1 first determines whether or not any operation has been performed on the parent device 30 or the wireless slave device 50 (step S11). If it is determined that the operation has been performed, the operation is then performed. It is determined whether or not the operation of the outside line key of the parent device 30 is performed (step S12). If it is determined that the operation is an operation of the external line key of the master unit 30, it is next determined whether or not the wireless slave unit 50 is idle (standby) (step S13). Here, the idle state is a state in which the wireless handset 50 is not placed on the base unit 30 but is not off-hook. For example, after the call is finished, the line is disconnected by operating the end key of the operation unit 57. The wireless slave device 50 is not returned to the placement unit 30-a of the master device 30 later. If it is determined that the system is idle, the control is performed so that the dial tone is output by setting the speaker of the base unit 30 in the receiving state (step S14), and the process is terminated.

  If it is determined in step S32 that the operation is not an operation on the external line key of the master unit 30, it is determined whether or not the flash key is pressed on the master unit 30 (step S15). It is determined whether or not the handset 50 is in an external line call (step S16). If the wireless handset 50 determines that an external line call is in progress, the wireless handset 50 disconnects the line on which the call is being made, re-acquires the line, places the handset of the wireless handset 50 in a call state, and dials tone from the handset. Is controlled so as to be output (step S17). Here, it is assumed that the external telephone call of the wireless slave device 50 is performed not by the speaker but by the handset.

  If it is determined in step S15 that the flash key of the parent device 30 has not been pressed, and if it is determined in step S16 that the wireless slave device 50 is not in an external line call, other processing is performed (step S18). ).

  As described above, if the master unit 30 captures an outside line while the wireless slave unit 50 is idle, the master unit 30 enters a call state, and the key operation of the master unit 30 becomes effective. In addition, when a flash operation is performed on the parent device 30 during a call by the wireless slave device 50, a dial tone is output from the handset of the wireless slave device 50, so that operability is improved. In step S15, not the flash operation but the operation of once releasing the outside line and capturing the same or different outside line again is processed in the same manner.

[4] When operating the external line capture key of the main unit 30 (FIG. 7)
The control unit 11 of the main device 1 determines whether or not an outside line key provided in the operation unit 36 of the parent device 30 has been pressed (step S21). Key operation of the operation unit 36 of the base unit 30 is detected by the base unit control unit 31 and transmitted to the extension interface unit 13 of the main unit 1 via the extension interface unit 32 and the extension 2. The unit 11 can determine whether or not the outside line key of the base unit 30 has been operated by monitoring the state of the extension interface unit 13.

  If it is determined that the outside line key of the master unit 30 has been operated, it is next determined whether or not the wireless slave unit 50 is off-hook (step S22). As described with reference to FIG. 4, since the off-hook of the wireless slave unit 50 is transmitted to the extension interface unit 13 of the main apparatus 1 via the master unit 30, the control unit 11 of the main apparatus 1 By monitoring the state of 13, it is possible to determine whether or not the wireless slave device 50 is off-hook.

  If the wireless handset 50 is off-hook, control is performed so that the handset of the wireless handset 50 is in a talking state and a dial tone is output from the handset (step S23), and the wireless handset 50 is not off-hook. Controls the dial tone to be output with the speaker of the base unit 30 in the receiving state (step S24). If it is determined in step S21 that the outside line key of the parent device 30 has not been pressed, the process is terminated.

  As described above, since the handset of the wireless slave device 50 is in a talking state when the external line is captured by the master device 30 during the off-hook of the wireless slave device 50, the key operation of the wireless slave device 50 is enabled, The operability of the slave unit 50 is improved.

[5] When the flash key of the main unit 30 is operated (Fig. 8)
The control unit 11 of the main apparatus 1 first determines whether or not the flash key provided in the operation unit 36 of the master unit 30 has been pressed (step S31). It is determined whether or not the handset 50 is in an external line call (step S32). If the wireless handset 50 determines that an external line call is in progress, the wireless handset 50 disconnects the line on which the call is being made, re-acquires the line, places the handset of the wireless handset 50 into a call state, and dials the tone Is output (step S33). Here, it is assumed that the external telephone call of the wireless slave device 50 is performed by the handset, not the speaker. That is, it is a call after the outside line is captured in the process of FIG.

  If it is determined that the wireless handset 50 is not in an external line call, it is determined whether the base unit 30 is in an external line call (step S34). If the main unit 30 determines that an external line call is in progress, the main unit 30 disconnects the line on which the call is in progress, re-acquires the line, sets the speaker of the main unit 30 to the receiving state, and outputs a dial tone. Control is performed as follows (step S35). If it is determined that base unit 30 is not in an external line call, the process is terminated.

  As described above, when an external line re-acquisition operation is performed by the base unit 30 during an external line call on the wireless handset 50, the handset of the wireless handset 50 is placed in a talking state and a dial tone is output from the handset. Improves. In step S31, the same operation is performed for the operation of once releasing the outside line and capturing the same or different outside line instead of the flash operation.
