If the instruction detection unit 13 detects the pressing of the hard key on which the character is displayed while displaying a character for a normal numeric keypad, the browser processing unit 14 does not determine that the selection object is a selection acceptance instruction. It is determined that the instruction to accept input of characters into the input area is made, and the input characters are displayed on the display unit 30. When the instruction detection unit 13 detects that the enter key is pressed (instruction for termination of acceptance of character input to the input area), the browser processing unit 14 terminates acceptance of character input and displays a character for a normal numeric keypad. The image displayed on the key display unit 41 before the display is displayed on the key display unit 41 again.

  When the user selects a control capable of selecting an item, such as a pull-down menu, a combo box, or a list box, the instruction detection unit 13 detects pressing of a hard key on which the control is displayed. In this case, the browser processing unit 14 may display selectable items (character strings and images) in the control on the key display unit 41. For example, when a pull-down menu capable of selecting 47 prefectures is displayed on the display unit 30, when the instruction detection unit 13 detects pressing of a key displaying the pull-down menu, the browser processing unit 14 The characters indicating the prefecture may be displayed on each key display unit 41. When the instruction detection unit 13 detects the pressing of the hard key on which the item is displayed while the item is displayed, the browser processing unit 14 determines that the item is a selection acceptance instruction. For example, when the pressing of the hard key displayed as “Hokkaido” is detected, the browser processing unit 14 accepts the selection of “Hokkaido” and changes the display of the pull-down menu of the display unit 30 to “Hokkaido”. Then, the browser processing unit 14 displays again the image displayed on the key display unit 41 before displaying the selectable items on the key display unit 41.

  When the number of selection items is larger than a predetermined number (for example, the number of hard keys), the browser processing unit 14 assigns a predetermined number of items to different key display units 41 among selectable items. It may be displayed. In this case, the browser processing unit 14 may assign a function for switching an item to be displayed to a predetermined hard key. When the instruction detection unit 13 detects pressing of the hard key, the browser processing unit 14 Items that are not displayed are displayed on the key display unit 41.

(Operation in which the selected object detection unit 15 detects the selected object)
When the browser processing unit 14 detects scrolling of the browser screen displayed on the display unit 30, the browser processing unit 14 extracts a tag of a portion displayed on the display unit 30 from the HTML document read by the browser processing unit 14. When the browser processing unit 14 detects a link tag such as an a tag or a base tag from the extracted tags, the portion surrounded by the link tag (starting anchor) is a character string that does not include the tag. The character string is displayed on the key display unit 41. For example, if a tag such as <P><Ahref=http://www.abc-xyz-inc.co.jp/products/tv/> TV recorder </A></P> is detected, The anchor “TV recorder” is displayed on the key display unit 41.

  Further, when the browser processing unit 14 detects an INDEX tag whose TYPE attribute is text in the extracted tag, the browser processing unit 14 displays an image representing a text box on the key display unit 41.

  Similarly, for other selected objects, when the browser processing unit 14 detects a tag representing the selected object, the browser processing unit 14 displays an image representing the selected object on the key display unit 41.
