Abstract

PURPOSE:To simplify the structure and to attain ease of handling by providing a base station connected to a telephone line, a hand set operated in cooperation with the said base station, a response switch as an operation switch of the base station and a call switch. CONSTITUTION:A call tone from a telephone line inputted by a telephone cord 2 and an INTERCOM call tone from the handset inputted from an antenna 5 are outputted from a speaker 4 and when a response switch 11 is depressed, the set is connected to a telephone line or the handset, the voice of the opposite party is listened to from the speaker 4, the own voice is inputted from a microphone 3 and the voice is transmitted as the signal. When the talking is finished, the response switch 11 is depressed once again and the base station is restored to the initial state. When the handset is desired to be called, the call switch 12 is depressed regardless of distinguishment of the INTERCOM or transfer, the handset produces a call tone. When the handset responds thereto, the base station and the handset are communicated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a cordless telephone having a handset device.

[Conventional technology]

FIG. 5 is a perspective view of a conventional cordless telephone.

In the figure, (1) is a base station connected to the telephone line by cord (2), and a microphone (31 and speaker (4) is installed on the top, as well as an anti-95 for transmitting to the handset). , and a speakerphone switch (6), 1-line hold switch (7), intercom switch +81191, and transfer switch (11) on the top.
It is equipped with.

A conventional cordless telephone is constructed as described above and has 1I
If you receive a call from the telephone line C, press the speakerphone switch (6) t-, and the audio from the telephone line will be sent to the speaker +4.
The voice played at 1 and spoken at 9 is input from the microphone (3).

When you want to transfer the telephone line to the handset, first press the line hold switch (7), then use the intercom switch (8) to call the handset, and after the other party responds on the handset.

Just press the transfer switch H. Also, when communicating between the base station and handset, use the intercom switch (
91t-Press. Communication with the handset naturally takes place via the antenna (5).

[Problem that the invention seeks to solve]

Conventional cordless telephones such as those mentioned above have many functions that allow transmission from a base station to a handset and communication between the two.

Each function requires an operation switch, which increases the number of parts, complicates the structure, and makes handling difficult.

The present invention was made to solve these problems, and an object of the present invention is to provide a cordless telephone that is easy to handle by reducing the number of operation switches.

[Means for solving problems]

The cordless telephone according to the present invention is intended to combine the base 4-degree operations into two functions, a response function and a call function, and to provide a response switch and a call switch for each function.

[Effect]

In this invention, it is possible to switch the telephone line reception cutoff function, intercom call response function, transfer function, etc. by appropriately operating the response switch and the call switch.

〔Example〕

Fig. 1 is a perspective view showing an embodiment of the present invention, where the mountain is connected to a telephone line by a cord (2), and a microphone (3) and a speaker (41'ii) are placed on the upper surface of the station, as well as a handset. IJD is a response switch placed on the top of pace station III, and u3 is a call switch.

The ringing tone from the telephone line input from the telephone cord (2) and the intercom ringing tone from the wireless receiver inputted from the antenna (5) are emitted from the speaker (4), and responses to them are made by pressing the response switch α11.
When you press , you are connected to a telephone line or handset, and you hear the other party's voice from the speaker (4), and your own voice is input to the microphone (3) and the voice is sent as a signal. When the call is finished, pressing the response switch again returns the base station to its initial state. Also, when you want to call the handset, regardless of whether you are using an intercom or for transfer, press the ring switch 112f and the handset will emit a ring tone.If the handset responds, the base station will You can make calls between the and handset. Handset tl - If the call is for transfer purposes, the telephone line is held.

The handset response is 69. The operation of transferring the telephone line has the same meaning as ending a call, so pressing the response switch a3 completes the transfer.

FIG. 2 shows the general flow of software that enables the functions described above. After the power is turned on, the program waits in the initial state, and when a call is received, it only accepts processing for response switches. on the other hand,
When making a handset call, only the call switch is accepted. When each switch is pressed, either the response switch processing routine or the call switch processing routine is jumped to. If the switch is not pressed (in the case of a call switch, it will of course return to the initial setting), but only when a call is received.
A routine is required, and the switch is checked for turning on within one hour of the timer, but once the one hour timer has elapsed, it is necessary to return to the initial state. The purpose of inserting this timer is to omit the operation of holding down the call switch when calling a pace station from the handset.

The object of the present invention is to return to an initial state when a response switch is not turned on from a call reception state, and to set the operation of the call switch to a state where the response is turned on.

FIG. 3 shows the response switch processing routine.

It makes judgments based on the state before the response switch is pressed and moves to each operation. If the answer switch is pressed while receiving a ring tone from the telephone line, the base station will connect to the telephone line as a speaker horn, and if the answer switch is pressed while operating as a speaker horn, the base station will connect to the telephone line. Please cut off the connection to the line to end the call. When receiving an intercom call, the intercom responds by allowing conversation with the handset. After the call to the line is held and acts as an intercom, it acts as a transfer of the line to the node set.

FIG. 4 shows the processing routine of the call switch. When making a call, if the call switch is pressed in the initial state, the handset is called as an intercom. If you press the call switch while talking to the 1!21 line, the first line will be put on hold and the handset will become an intercom call for the purpose of transfer.

If you process the program as shown below, you can install two operation switches, an answer switch and a ring switch, on the base station, and you can use the function to interrupt calls from the telephone line, and the function to temporarily connect the telephone line to the handset using an intercom. Ability to transfer after.

It should be possible to perform multiple functions such as intercom response and calling functions with easy-to-understand and simple operations.

〔Effect of the invention〕

As described above, according to the present invention, by providing two operation switches, an answering switch and a calling switch, in the base station, functions such as disconnection of telephone lines, intercom, and even transfer can be performed, and the structure is simplified. This has the effect of making handling easier.
