[Problem that the invention seeks to solve]

In the conventional button telephone device configured as described above, since the number of display pixels and the number of characters displayed on the LCD provided in the button telephone device are small, the displayed contents are limited to numbers, alphabetic characters, or specific pictograms. therefore,
For example, it is difficult to respond to requests such as displaying the contents of a message such as a message to an absent person or convening a meeting, or transferring the message contents to another telephone. This is not only due to the small number of characters displayed on the LCD provided on the key telephone, but also because the group of numeric buttons provided on the key telephone are unsuitable for inputting characters such as the content of messages. This is also because the key telephone device does not have a processing function to process this information.

The present invention has been made to solve the above-mentioned problems, and aims to enable character input and display of character information such as messages.

[Means for solving problems]

In the button telephone device according to the present invention, the display device provided on the button telephone is composed of a display device capable of displaying text information such as messages, and the main device CPU is provided with text information that stores text information and text information processing commands.
