As shown in the figure, the liquid crystal display section 171 is provided with a message display section 172 for displaying message information, and the message display section 172 has a plurality of unit areas 173 of a predetermined size (dot number). Is divided into The unit area 173 is an area in which a display unit such as one character and one number is displayed.

When the conventional individual selective call receiver having the liquid crystal display unit 171 receives a call signal including message information addressed to itself, a display unit such as one character or one number in the message information is displayed. The unit areas 173 are displayed one by one. Further, when the message information has a large number of digits and cannot be displayed on one screen, the screen is switched according to the operation of the wearer, and the message information is displayed over a plurality of screens.

[0006]

As described above, in the conventional individual selective calling receiver, the message display section for displaying the message information is divided into unit areas each having a predetermined number of dots, and each of the unit areas is displayed. Since the units are displayed one by one, there are the following problems.

That is, when the message display section is divided into a large number of unit areas, the number of characters or the like that can be displayed on one screen increases, and when long message information is displayed, the number of times screen switching is required decreases. . However, since the number of dots in the unit area is small, even when displaying short message information, characters and the like are displayed in small size, which makes the message information difficult to see.

Further, when the number of divisions of the message display section is reduced, the number of dots per display unit is increased, and the displayed message information is easy to see. However, when the message information is long, the number of screen switching times is increased. There is also a problem that you have to do.

An object of the present invention is to reduce the number of screen changes when displaying long message information by changing the size of characters or the like displayed on the message display section according to the length of the message information to be displayed. You can
An object of the present invention is to provide an individual selection call receiver that can display characters and the like in a size that is easier to see when displaying short message information.
