Hereinafter, a remote control mode using a handset according to the present invention will be described in detail with reference to the operation procedures of FIGS. 3 to 5.

First, the CPU 13 of the handset 10 shown in FIG. 1 performs initialization of the handset 10 in step S31 of FIG. 3A. Then, in step S32, is the handset 10 in charge mode? If it is determined that the charging mode is completed, the charging waits to be completed and returns to the initial stage when the charging is completed while the charging mode in step S33 determines whether the handset 10 is in the remote control mode.

If the result of the determination is NO, after scanning the key input unit from the keypad 12 in step S34 to perform call processing, it is determined whether the remote control key 11 is turned on in step S35. On the other hand, if YES, the remote control flag is set (SET) in step S36, and then the process returns to the initial stage, and the control procedure proceeds to step S37 according to the remote control mode setting judgment of step S33. That is, if the remote control flag is set in step S36 and then returned, and the setting of the remote control mode is determined in step S33 through steps S31 and S32, the control procedure proceeds to the process of FIG. In step S37, it is determined that the transmission of the remote control mode data to the fixing device 20 is completed. If the transmission is completed, the automatic response-related remote function (e.g., play and rewind) set in the key of the keypad 12 in step S38. By setting the key input enable state to enable the rewind, eject, and control input, the function control input is modulated by the RF modulator 14 to wirelessly transmit through the antenna ANT. Subsequently, in step S39, the CPU 13 of the handset 10 turns on the "CHARGE" and "TALK" buttons of the handset 10 or the "REMOTE KEY". It is determined whether there is a remote control mode OFF input according to the re-input, and when there is such a key input, the remote control completion data is sent to the fixing device 20 in step S40.

On the other hand, when the transmission of the remote control mode signal is not completed in step S37, the signal is repeatedly transmitted and received over a predetermined number of times (for example, three times) in step S41, and a response is returned from the fixing device 20. Next, the transmission completion flag of the fixing device 20 is set, and then the process returns to step S37. If the response from the fixing device 20 is not returned in step S42, all operations in step S44 are completed and then a standby state is reached.

In this regard, the main controller CPU 23 of the fixing device 20 performs the initialization in step S51 and then determines whether the wireless telephone is in the charging mode in step S52, and performs the corresponding mode until the charging mode is completed in the charging mode. If it is not in the charging mode, it is determined whether or not the remote control mode setting data (step S37) is input from the handset 10 in step S53. If no input is made, the automatic response cassette deck mechanism 27 Scan the auto answer function key to determine whether there is an auto answer function key input in step S55. If there is no key input, determine whether remote control mode setting data is received from the handset 10 in step S56. On the other hand, when there is an auto answer function key input in step S55 or when the remote control mode setting data is received in step S56, step S5. Proceeding to step 7 sets the fixing device 20 to the remote control mode, and then transmits the confirmation data in step S58 to return to the initial state.

Subsequently, after setting the remote control mode in steps S54 to S58, it is determined whether the remote control mode is set from the handset 10 again in step S53. In this case, the remote control mode in step S57. In step S59, it is determined whether the remote control auto response initialization state is completed. If NO, the enable signal is applied to the sub-control CP U 26 in step S60. Then, the remote control auto response initialization state is completed in step S61. Set the flag and return to the initial state. If it is determined in step S59 that the remote control auto-response initialization state is completed, it is determined whether the remote control termination data is received from the step S62 handset 10, and if received, the confirmation data is sent to the handset 10 in step S63, but not received. Otherwise, it is determined in the step S64 whether it is in the charged state and returns to the initial state if it is not in the charged state. On the other hand, if the confirmation data is sent in the step S63 or in the charged state in the step S64, the process proceeds to the steps S65 and S66 and the sub-control CPU 26 After the disable signal is sent to all the steps, all operations return to the initial state.

On the other hand, the sub-control CPU 26, in relation to the operations of the handset 10 and the main control CPU 23 shown in Figs. 3 and 4, first performs an initialization operation in step S71 and then the handset (in step S72). 10) It is determined whether the remote control auto answer control mode is set. If NO, it is determined whether there is an auto answer control key input of the auto answering mechanism 27. If the result is NO, the remote control is enabled by the handset. If it is determined that it is not in the enable state and returns to the initial state, while the auto-response control key input in step S63 or the remote control enable state is made in step S64, the remote control auto-response mode is set in step S65. In step S66, the remote control auto response flag is set and then returned to the initial state.

On the other hand, if the remote control automatic response mode is determined in step S62 as the remote control automatic response mode is set, the flow advances to step S77 to determine whether or not the remote control mode is set and the validity of the DTMF signal in step S78. If it is determined that NO is determined whether the remote control mode by the handset 10 is OFF in step S79, and if the determination result is NO, it is determined whether the charging mode is in step S80, and if NO, the initial state is returned, whereas in step S79 When the remote control mode OFF and the charging mode are determined in step S80, the process returns to the initial state after completing all operations in step S81.

On the other hand, if the invalidity of the DTMF signal is determined in step S78, it is determined in step S82 whether the key input from the keypad 12 of the handset 10 is FF, RWD, or PLAY in the remote control mode, and the corresponding step is performed in step S73. After performing the operation according to the key input, the process proceeds to step S78 to continue the subsequent operation. If NO in step S67, it is determined in step S74 whether or not a function key input such as PLAY, FF, RWD, etc. provided in the auto-response mechanism 27 is returned to its initial state. It determines and performs the same step after the said step S72.

As described above, according to the control apparatus of the wireless answering telephone using the handset according to the present invention, by applying a remote control function to the handset, it is possible to remotely control the fixing device of the wireless telephone, and also receive a message performed in the remote control mode. Since the user can listen to the result of the answering machine through the handset, the convenience in operating the radio answering machine can be further increased.
