Abstract

PURPOSE:To simply and quickly conduct dialing to an extension and an external line by using a detection signal representing the absence of charging state from a charger in place of a calling key operation signal. CONSTITUTION:When a radio telephone set 2a is placed on a charger 3a and an extension key for calling an extension is depressed, whether or not the radio telephone set 2a is removed from the charger 3a is discriminated. When the detection output of a charge detection circuit does not represent the charging state, it is regarded as the depression of the calling key, the extension number dial procedure is followed and when the extension number key is depressed, the signal of the extension number is sent. Thus, in the case of extension call, the extension key is depressed and then the radio telephone set 2a is removed from the charger 3a and the extension dialing is simplified quickly.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a wireless telephone device typified by a cordless telephone device.

(Prior Art) Conventionally, a parent device is connected to a wired telephone line, a wireless telephone is connected to the parent device via a wireless line, and the wireless telephone can be charged by being placed thereon. A wireless telephone device is known that includes a charger for charging a battery.

In such a wireless telephone device, a plurality of wireless telephones are arranged for one master device, and each wireless telephone can make external calls to the wired telephone line as well as make internal calls to the Ike's wireless telephone. There is something.

Conventionally, when making such an extension call, the following procedure is used to make an extension call.

(1) Remove the wireless telephone from the charger.

(2) Press the extension key on the wireless telephone to set it to extension mode.

(3) Press the call key on the wireless telephone to set it to call mode.

(4) Perform a dialing operation for the extension number of the other party's wireless telephone.

(Problem to be Solved by the Invention) However, in the above-described operation procedure for making an extension call, at least three steps must be completed before making an operation to make a call to an extension number, making the operation for making an extension call a hassle and time consuming. There was a problem that it took a while.

SUMMARY OF THE INVENTION An object of the present invention is to provide a wireless telephone device that can easily make extension calls.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides detection means for detecting whether or not the wireless telephone is in a charging state from a charger, and detects that the wireless telephone is no longer in a charging state. The feature is that the signal is used in place of the operation signal of the call key.

(Function) In the present invention, since the detection signal of the detection means indicating the charging state is used instead of the operation signal of the call key,
There is no need to operate the call key, making operation that much easier.

(Embodiment) FIG. 1 is a schematic system configuration diagram showing an embodiment of the present invention.
2n are arranged, and each of the wireless telephones 2a to 2n is provided with a charger 3a to 3n. The parent device 1 is connected to a wired telephone line 4.

FIG. 2 is a flowchart showing the extension calling operation in each of the radio telephones 2a to 2n. In step 10), when the button is pressed, the wireless telephone 2a connects to the charger 3a.
It is determined whether or not it has been removed from (step 11).

This is a charging detection circuit (not shown) inside the wireless telephone 2a that detects whether or not it is being charged from the charger 3a.
Judgment is made based on the detection output. If the detection output of this charging detection circuit does not indicate the charging state, it is assumed that the call key has been pressed, and the next step 1 is performed.
2 and subsequent extension number calling procedures, and if the extension number key is pressed in step 12, a signal for that extension number is transmitted (step 13).

Therefore, when making an extension call, it is only necessary to press the extension key and then remove the wireless telephone 2a from the charger 3a, making it possible to easily and quickly perform the extension call operation.

Note that if the extension key is not pressed, it is assumed that the system is in the outside line mode, and the dialed number input thereafter is treated as an outside line number, thereby making it possible to make an outside call with a simple operation.

[Effects of the Invention] As explained above, in the present invention, since the detection signal from the charger indicating that the charging state is no longer used is substituted for the operation signal of the call key, it is easy to make calls to internal and external lines. It can be done easily and quickly. Furthermore, by simplifying the calling procedure, it is possible to prevent mistakes in calling operations for internal and external lines.

Claims (1)

[Scope of Claims] The present invention consists of a parent device connected to a wired line, a wireless telephone connected to the parent device via a wireless line, and a charger for charging a battery built into the wireless telephone. , the radio telephone is equipped with a key for making a call, and the radio telephone device is configured such that operation of the key moves to a call control procedure for an extension number or an external number, the radio telephone being charged from a charger within the radio telephone. What is claimed is: 1. A wireless telephone device comprising: a detection means for detecting whether the battery is in a charged state; and a detection signal indicating that the battery is no longer in a charging state is used in place of the key operation signal.
