BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to charging of a driving battery for a cordless telephone, and more particularly to a display when the input power of the charger is cut off.

[0002]

2. Description of the Related Art In recent years, cordless telephones have been widely used. Many cordless telephones have a built-in driving battery, and when not in use, the cordless telephone is placed on an externally provided charger and charged through a charging terminal of the charger for use. The cordless phone has a structure that can be easily attached to and detached from the charger. It is in a standby state when charging, it accidentally comes off the charger, the AC input power of the charger is out of power, or the charger cord -If the cord goes off, there is a case that the call is mistakenly regarded as off-hook and a call is automatically made.

[0003]

However, as described above, in the conventional cordless telephone, if the power source is accidentally disconnected during the charging of the battery or a power failure occurs, the user makes a call from the cordless telephone. There is a problem in that the operation is considered to be a malfunction, or the user does not notice that the charging has been stopped and is not charged, so that the operation may be temporarily disabled.

The present invention has been made in view of the above-mentioned problems, and eliminates the above-mentioned problems, and when a cordless telephone battery is being charged and a power outlet is disconnected or a power failure occurs, a voice message is displayed. It is an object of the present invention to provide a cordless telephone that outputs a message or an alarm.

[0005]

In order to solve the above-mentioned problems, the present invention, as shown in FIG. 1, incorporates a driving battery 1-5 and is installed outside the driving battery 1-5. In the cordless telephone 1 configured to supply the charging current from the charger 2, the charging detector 1-9 for detecting the charging current or the voltage supplied to the driving battery 1-5 for the cordless telephone 1. A determination unit 1-6-2 for determining whether or not charging is detected by the charge detector 1-9, a sound source signal generation unit 1-6-3 for outputting a message or alarm signal, - installation terminals T _13, T ₁₄ for detecting that the dress phone 1 is installed in the charger 2 is provided, co - when the dress phone 1 is installed in the charger 2, installed terminals T _13, T ₁₄ A short-circuit piece 2-2 for short-circuiting is installed in the charger 2, and the cordless telephone 1 is connected to the charger 2. When location, installed terminals T _13, T ₁₄ in the short-circuit state, and the determination unit 1-6-2 when it is determined that in a non-charging state, issues a drive signal to the sound source signal generating unit 1-6-3 said It is characterized in that the sound source signal generator 1-6-3 is driven.

According to the present invention, by adopting the above configuration,
When the cordless telephone 1 is installed in the charger 2, the installation terminals T ₁₃ and T ₁₄ are connected to the shorting piece 2 via the charging terminals T ₂₃ and T _24.
-2 and the determination unit 1-6-2 is short-circuited with the charge detector 1
When it is determined to be the non-charged state detected by -9, it is determined that the power source is abnormal (when the outlet 3 is disconnected or a power failure occurs), and the drive signal is output to the sound source signal generation unit 1-6-3 to generate the sound source signal. From the unit 1-6-3, for example, a sound such as "Taedendez" or an alarm such as "beep-beep" is issued to notify the user of the power failure. This allows the user to take appropriate measures immediately.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a diagram showing a configuration example of a cordless telephone and a charger 2 of the present invention. As shown in the figure, the cordless telephone 1 of the present invention has an antenna 1-1,
Communication circuit 1-2, handset 1-3, rectifier 1-4, battery 1-5, controller 1-6, amplifier 1-7, speaker 1-
8, charging detector 1-9, charging terminals T ₁₁ , T ₁₂ , installation detection terminals T ₁₃ , T _{14 and the} like.

Further, the charger 2 for charging the battery 1-5 of the cordless telephone 1 has a short-circuit piece (or short-circuit line) 2-2 for short-circuiting the charge control section 2-1 and the installation detection terminals T ₂₃ and T _24. comprises a power supply is AC100V is supplied through the outlet 3, the charging control unit 2-1 converts AC power to appropriate DC voltage charging terminal T _21, T _22, via the charging terminal T _11, T ₁₂ cell Supply charging current to 1-5.
