The contact pen 1 has a size and shape similar to those of, for example, a pencil, a ballpoint pen and a fountain pen, and its tip 2 is rounded and therefore not sharply pointed. Therefore, the input area 5 is not damaged by the tip 2. The contact pen 1 may be made of a material such as metal or synthetic resin.

A character input area 5 is provided in a flat plate-shaped casing 4 of the character input means 3, that is, a card-shaped or sheet-shaped casing 4. The character input switch 7 for each of the many characters provided in the character input area 5 is selectively

Output means 15 such as a liquid crystal display means for visual display
And a fist of a hand holding a contact pen is placed on a table such as a table 31 on which the casing 4 is placed. For example, horizontal l1 = 8.5 cm, vertical l2 = 5.4 cm
And the planar shape is almost equal to the size of a credit card.

FIG. 3 is an enlarged plan view of the character input area 5. Vowels of English characters are vertically arranged near the upper part of the character input area 5. This makes it easier to search for English letters, and it is also easier to input Japanese in Roman letters. Character input switches for inputting numbers and symbols are also arranged. Characters with a high frequency of use of each character are arranged to the left of FIG. 3, and characters with a low frequency of use are arranged to the right of FIG.
The vertical length g of such a character input area 5a is, for example, about 3 to 5 cm, and the horizontal length h may be the same. In the character input area 5, there are also function keys 22 for selecting uppercase or lowercase English letters.
