摘要:
A contact sensor capable of inputting a character by tracing a character with user's finger is arranged in a region of a ten-key unit of a mobile telephone. When registering a password to release a key lock, a user traces a shape of a line, a character, a number, or other symbol on the contact sensor with his/her finger so that the shape is inputted and stored in a memory, thereby completing registration of a password. When releasing the key lock, the user traces the registered shape on the contact sensor with his/her finger so that the key lock is released. The input is easy. Even if the password input operation is observed by a third person, the password will not be easily known to the third person.

An input device capable of avoiding simple input of the correct password and a portable telephone device are provided. A contact sensor (56) enabling input of a line by moving a finger of the user on an area where numeric keys (48) of a portable telephone (10) are arranged is provided in the area. When password information for canceling key-lock is registered, the user moves a finger of the user on the contact sensor (56) to input a linear shape. The data on the key with which the user first comes to contact when the user tries to input the line and the data on the key from which the user separates the user's finger last are registered for each place, thus completing the registration of the password. When the user wants to cancel the key-lock, the user operates the contact sensor similarly to the registered content. Then the key-lock is canceled.

A display device includes a condition judgment unit which judges whether a received email satisfies a predetermined condition. Moreover, the display device includes a data deletion unit which deletes attached data in an email from a recording unit if the condition judgment unit detects that the email does not satisfy the predetermined condition. Moreover, the display device includes a condition registration unit which receives a condition for storing attached data. The condition registration unit receives a transmission source email address of an email which a user desires to store. When an email is received by the email reception unit, the condition judgment unit judges whether the transmission source email address coincides with a part or whole of the reception-enabled address. If yes, the attached data is stored. Otherwise, the data is deleted.
