As described above, even in the conventional key telephone device with a voice storage function, it is possible to know whether or not the contents of the call are stored by observing the lighting of the lamp.

[0008]

However, in the conventional button telephone apparatus with a voice storage function, the time elapsed after the content of the call is stored cannot be determined only by turning on the lamp. Therefore, there is a problem that the call contents are likely to be left for a long time without being heard.

The present invention solves such a conventional problem by notifying the elapsed time after the storage of the call contents from the change of the display state and leaving the stored call contents for a long time. It is an object of the present invention to provide an excellent button telephone device that can prevent the above.

[0010]

In order to achieve this object, the key telephone apparatus of the present invention has a storage unit for storing the contents of a call after an incoming call and a storage unit for storing the contents of the call. Display means for indicating that the call content is stored, elapsed time counting means for measuring the time after the call content is stored in the storage means, and display means according to the elapsed time after the call content is stored This is a configuration including control means for performing control for changing the display method of.

Further, the display means is composed of a lamp and a synthesized voice output means, and the blinking of the lamp and / or the synthesized voice output is performed according to the elapsed time from the storage of the call contents.

[0012]

With such a configuration, the key telephone apparatus of the present invention measures the time after storing the call content and displays the display method of the display means according to the elapsed time from the storage of the call content. Since it is changed, it is possible to prevent the stored call contents from being left for a long time.
