That is, in FIG. 1, reference numeral 100 is a master unit having a facsimile function with a built-in facsimile, and 200 is a slave unit that can communicate with the master unit 100 wirelessly.

  In the base unit 100, L is a telephone line, 110 is a base unit control unit, 120 is a connection switching unit, 130 is an incoming call detection unit, 140 is a base unit wireless communication unit, 150 is a base unit call unit, 160 is a facsimile communication unit, 161 is a facsimile printing unit, 162 is a facsimile document reading unit, 170 is a master unit input unit having various buttons and keys, 171 is a communication start button as a communication start unit in the master unit input unit 170, and 180 is a master unit. It is a display means.

  The base unit control unit 110 includes a facsimile switching unit 111, and the facsimile switching unit 111 includes an incoming flag 112 and a remote reception control unit 113. Is start determination means. In the base unit 100, when the incoming call detection unit 130 detects an incoming call, the base unit control unit 110 sets the incoming flag 112 in the facsimile switching unit 111 to ON.

  On the other hand, in the slave unit 200, 210 is a slave unit control unit, 240 is a slave unit wireless communication unit, 250 is a slave unit call unit, 270 is a slave unit input unit having various buttons and keys, and the slave unit input unit 270. Is provided with a remote reception key 271 for instructing the parent machine to receive a facsimile. 260 is a communication start means, and 280 is a slave display means. When a call is made from the slave unit 200, a numeric keypad and various function keys (not shown) provided on the slave unit input unit 270 are operated to make a call via the slave unit control unit 210 and the slave unit call unit 250. You can make a call by making an incoming call.

  The base unit control means 110 is composed of a microprocessor, and controls each unit described below based on, for example, a system program stored in a ROM (Read Only Memory). Further, the base unit control means 110 transmits and receives data such as facsimile control signals and mails, or receives a call notification signal indicating that a mail has arrived at the server, a modem having a DSP (Digital Signal Processor), connection switching Conversion means for mutually converting an analog signal and a digital signal with the means 120 is also incorporated. The incoming call detection means 130 is connected to the telephone line L, detects an incoming signal of 16 Hz from the telephone line L, sends it to the parent device control means 110, and detects a facsimile incoming call. Under the control of the base unit control unit 110, the connection switching unit 120 communicates voice signals with the base unit call unit 150, facsimile data with the facsimile communication unit 160, and a mailer in the base unit control unit. In the meantime, the switching control is performed to sort the data such as the mail contents.

  The parent device 100 and the child device 200 are connected wirelessly, and the parent device wireless communication means 140 wirelessly outputs a call or control signal from the telephone line L to the child device 200 via the parent device wireless communication means 140. Then, the slave unit wireless communication means 240 receives this. The slave unit wireless communication unit 240 of the slave unit 200 wirelessly outputs a call or facsimile reception instruction or the like to the master unit 100 via the slave unit wireless communication unit 240, and the master unit wireless communication unit 140 receives this. . The base unit call unit 150 of the base unit 100 and the slave unit call unit 250 of the slave unit 200 have a hook detection unit that detects an on-hook or an off-hook of the handset or the handset, and can make a phone call.

  When there is an incoming call on the telephone line L in the base unit 100, the incoming call detecting means 130 detects the incoming call. Subsequently, the incoming call detection means 130 sends an incoming call detection signal to the facsimile switching means 111 in the base unit control means 110, and the facsimile switching means 111 sets the flag of the incoming call flag 112 to the “on” state. The incoming flag 112 is reset to the “off” state when the telephone call or facsimile communication is completed.

  In the facsimile switching means 111, when the flag of the incoming flag 112 is set to the “on” state, the remote reception control means 113 receives a remote reception signal for instructing facsimile reception from the slave unit 200 (the slave unit 200 described later). The signal transmitted to the base unit 100 by operating the remote reception key is validated. When the flag of the incoming flag 112 is in the “off” state (when no incoming call is detected), the remote reception control means 113 invalidates the remote reception signal received from the slave unit 200.

  As a result, even if the remote reception key of the slave unit 200 is erroneously operated during a call after the call is made and the master unit 100 receives a remote reception signal from the slave unit 200, the remote reception control unit 113 does not receive the remote reception key. Since the received signal is invalidated, it is not switched to facsimile reception, and the call is not disconnected in the middle.

  The facsimile communication means 160 controls the facsimile communication procedure with the partner machine through the telephone line L based on the signal from the facsimile switching means 111, transmits the image data from the document reading means 162, and the image from the partner machine. Data is output to the printing means 161.

  The operation procedure of the above cordless telephone will be described with reference to the flowcharts of FIGS. FIG. 2 shows an operation procedure of the parent device 200, and FIG. 3 is a flowchart showing an operation procedure of the child device 100. In FIG. 2, when the operation of base unit 100 is started, it is determined whether there is an incoming call in the process of step S10. If it is not an incoming call, it is determined whether or not a call is made in the process of step S13. If it is not a call, other processing is performed in step S14, and the process returns to step S10. If it is a call in step S13, the process proceeds to step S15.

  In step S15, base unit control means 110 turns off the incoming call flag, and proceeds to step S12.

  If there is an incoming call in step S10, base unit control means 110 turns on incoming flag 112 in step S11 and advances the process to step S12.

In step S12, the parent device control means 110 starts a call between the outside line and the parent device (or child device). Specifically, for example, when a call is started between an outside line and a slave unit, when the incoming call detection unit 130 detects an incoming call, the master unit control unit 110 controls the master unit wireless communication unit 140 to When a signal indicating that there is an incoming call is sent to the unit, the ringer of the slave unit rings and the user of the slave unit responds to the incoming call, a signal indicating that the slave unit responds to the incoming call is transmitted. The base unit wireless communication means 140 receives the signal. Thereafter, under the control of the master unit control unit 110, the connection switching unit 120 connects the line L and the master unit wireless communication unit 140, and the slave unit is connected via the connection switch unit 120 and the master unit wireless communication unit 140. The line L is connected.
In this embodiment, since the operation of the slave unit to be described later is also related, the communication start in step S12 is, for example, a call between the slave unit and the external line via the master unit.

  If the base unit wireless communication unit 140 determines in step S16 that the base unit wireless communication unit 140 has received a signal indicating a facsimile remote reception instruction from the slave unit, the base unit control unit 110 proceeds to step S17. Proceed with the process.

  In step S17, if the incoming flag 112 is not "ON", the facsimile switching means 111 transmits an END signal to the handset 200 in the process of step S18. As will be described later, when receiving the END signal from the parent device 100, the child device 200 ends the signal transmission of the remote reception instruction of the facsimile using the remote reception key. On the other hand, if the incoming flag 112 is “OFF” in step S17, the process proceeds to step S22.

  If there is no remote reception instruction from the slave unit 200 in the process of step S16, the facsimile switching unit 111 performs facsimile operation by operating the facsimile reception key of the master unit 100 (communication start button of the master unit input unit 170) in the process of step S19. It is determined whether there is a reception instruction. If there is no facsimile reception instruction signal from base unit 100, the process proceeds to step S23, and if there is a facsimile reception instruction signal, it is determined in step S20 whether the incoming flag 112 is "ON". If the incoming flag is “ON”, the process proceeds to step S22. In step S22, the base unit control unit 110 controls the connection switching unit 120 so that the connection switching unit 120 is connected to the line L and the base unit wireless communication unit. The state is switched from the state where 140 or the base unit call means 150 is connected to the state where the line L and the facsimile communication means are connected. Thereafter, reception of the facsimile is started.

  If the incoming flag 112 is not “ON”, the facsimile switching means 111 does not accept a facsimile reception instruction by operating the facsimile reception key (communication start button of the parent machine input means 170) in the parent machine 100 in the process of step S21. Proceed to the process.

  In the process of step S23, it is determined whether or not the communication is finished. If the communication is not finished, the process returns to the process of step S16. If the communication is finished, the line is disconnected in the process of step S24. The process ends.

  Next, the operation of the slave unit will be described. The flowchart of FIG. 3 shows an operation when the parent device and the child device are connected wirelessly and the child device is in an external line call state.

  In the flowchart of FIG. 3, in step S30, a call between the slave unit and the outside line is started. In the subsequent step S31, the handset controller 210 determines whether or not the remote reception key 271 has been operated. If the remote reception key 271 has not been operated, it is determined in step S33 whether or not the call has ended. If communication has not ended, the process returns to step S30, and if communication has ended, the process returns to step S37. Proceed to processing.

  If the remote reception key 271 is operated in the determination process of step S31, the slave unit 200 transmits a facsimile reception instruction signal to the master unit 100 in the process of step S32. Then, it is determined whether or not an END signal has been received from base unit 100 in the process of step S34. If it is determined in this determination process that the END signal has been received, transmission of the facsimile reception instruction signal is terminated in step S36, and the process proceeds to step S37.

  If it is determined in step S34 that the END signal has not been received from the parent device 100, it is determined in step S35 whether communication has ended. If communication has not ended, the process proceeds to step S32. Returning, if communication is completed, the process proceeds to step S37. In the process of step S37, since the communication is terminated, the line is disconnected and the process of the slave unit 200 is terminated.

  Although the present embodiment has been described with respect to an incoming call, the incoming call in step S10 may be an incoming facsimile control signal.

  In the embodiment described above, the example in which the slave unit 200 is provided with the remote reception key 271 has been described. However, a facsimile transmission for setting a document to be transmitted by facsimile to the master unit 100 and transmitting the facsimile from the slave unit 200 is performed. It is also possible to provide a facsimile transmission key on the slave unit so that a signal can be transmitted to the master unit 100 for transmission operation.

  As described above in detail, according to the cordless telephone having the facsimile function according to the present invention, when the incoming call detecting means does not detect the incoming call, the remote reception control means invalidates the remote reception command and When the detection means detects an incoming call, the remote reception control means validates the remote reception command. As a result, if the remote reception key of the slave unit is accidentally operated during a call after the master unit or the slave unit has made a call, the remote reception control means invalidates the remote reception command. There is no switching to the facsimile reception mode, and there is no problem that the line during a call after a call is disconnected is disconnected.
