2. Description of the Related Art In general, a cordless telephone uses radio communication to relieve the trouble of the cord of a conventional telephone and to move freely within a radio wave coverage area (communication area) between a master unit and a slave unit. In recent years, it has been spreading rapidly.

[0003] Such a cordless telephone has a structure of a handset, which has an earpiece and a microphone in the same manner as a handset of a wired telephone, and also removes a so-called curl cord in the wired telephone, thereby resulting in a connection with the parent machine. It has a new configuration including a wireless unit for performing wireless communication, a secondary power supply, a dial key, and the like.

[0004]

Therefore, at the time of a call, as in the case of a handset of a wired telephone, a satisfactory call cannot be made unless the child device is picked up, the earpiece is put on the ear, and the microphone is brought close to the mouth.

[0005] In particular, when dialing a call, first press the talk button (off-hook button) with the cordless handset removed from the ear, then put the earpiece on the ear once to check the dial tone, and then release the earpiece again. There was a problem that a dial operation had to be performed. If zero transmission is required, the work of touching and releasing from the ear is required again.

[0006] Also, during a call, when both hands are closed, there is a problem that the handset must be held between the shoulder and the cheek and supported, or in some cases, placed on a desk or the like. In addition, when the slave unit is supported by the shoulder and the cheek or placed on a desk or the like, there is also a problem that the hook button is accidentally hit and the call is disconnected.

The present invention has been made in view of the above-mentioned circumstances, and the object is to enable a telephone call without removing the child device from a desk or the like, and also to make an off-hook dial and a hands-free call using the child device. It is to provide a cordless telephone.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an electrical configuration of the cordless telephone according to the present invention. In the figure, the output of an antenna 8 forming a bidirectional wireless channel with an antenna of a base unit (not shown) is output by a wireless transmitting / receiving unit 9.
The output of the wireless transmission / reception unit 9 for transmitting the voice signal of the other party's party sent from the base unit is connected to one end of the earpiece switch 10 and one end of the speaker switch 11, respectively. I have. The other end of the earpiece switch 10 is connected to the built-in earpiece 2 via the earpiece amplifier 13, and the other end of the speaker switch 11 is newly connected via the speaker amplifier 14. The speaker 3 is provided. The output of the built-in microphone 4 is connected to the other end of the microphone switch 12 via the microphone amplifier 15, and one end of the microphone switch 12 is connected to the wireless transmission / reception unit 9.

On the other hand, the microcomputer 16 for controlling each section in the slave unit 1 and the wireless transmitting / receiving unit 9 are bidirectionally connected, and the wireless transmitting / receiving unit 9 is controlled by a control signal from the microcomputer 16. A predetermined operation is performed. Further, the microcomputer 16 is configured to receive, via the wireless transmission / reception unit 9, various kinds of information on establishing a communication line between the master unit and the partner terminal. The microcomputer 16 is guided by the microcomputer 16 to the output of the off-hook button 5, the output of the speakerphone button 6, and the output of the dial button 7 composed of a numeric keypad. For each switching control input of the switch 11 and the microphone switch 12, a switching control signal indicating the timing of each switching operation is transmitted.

Next, the operation of the cordless telephone having the above configuration will be described with reference to the case of on-hook dialing as an example.

In an initial operation state, the earpiece switch 10, the speaker switch 11, and the microphone switch 12 are all in the OFF state, and the wireless transmission / reception unit 9 is in a standby state for reception and transmission.

In this state, when the user presses the off-hook button 5, the microcomputer 16 detects this and sends a control signal for instructing the wireless transmission / reception unit 9 to start transmission. A line connection is made, and a switch control signal for instructing a switch ON is transmitted to a switch control input of the speaker switch 11. As a result, the speaker switch 11 is turned on, so that the wireless transmission / reception unit 9 outputs a dial tone of “two” via the speaker switch 11, the speaker amplifier 14, and the speaker 3.

Since the speaker 3 has a higher output than the earpiece 2, the tone "two" is emitted from the earpiece 2.
It is output at a level that can be heard sufficiently even when the ear is not near. Thereafter, by dialing the telephone number of the other party using the dial button 7, a call signal is transmitted from the wireless transmission / reception unit 9 to the telephone line via the antenna 8 and the base unit (not shown). At this time, if the other party is busy, a sound "two, two ..." is heard from the speaker 3 indicating that the other party is talking. Also, when the other party is being called, a sound "Toruru, Toruru ..." indicating that the other party is being called is heard.

When the other party responds to this call, the microcomputer 16 detects this via the wireless transmission / reception unit 9 and switches the microphone control switch 12 to the switch control input to indicate the switch ON. A control signal is transmitted to turn on the microphone switch 12. As a result, it is possible to automatically start a so-called hands-free call in which a call is made while the slave unit 1 is placed on a desk or the like.

When the speaker phone button 6 is pressed when the other party answers the call, the microcomputer 16 detects this and sends a switching control signal for instructing the speaker switch 11 to be turned off. , Switch on earpiece switch 10
Is transmitted. As a result, the speaker switch 11 is turned off, the earpiece switch 10 is turned on, and the earpiece 2 and the microphone 4 are turned off.
And a normal telephone call can be made. Further, when the speakerphone button 6 is pressed during a normal call, the microcomputer 16 that detects this presses the earpiece switch 10 to the OFF state and the speaker switch 11 to the ON state, thereby switching to the hands-free call again. be able to. Similarly, when the speakerphone button 6 is pressed during a hands-free call, the microcomputer 16 that has detected this presses the earpiece switch 10 to the O position.
Since the N state and the speaker switch 11 are in the OFF state, it is possible to switch to a normal call between the earpiece 2 and the microphone 4.
