Terminal device with built-in image sensor

A terminal device with built-in image sensor comprising

• a main body incorporating a display unit for displaying information including at least one of character and picture,
• a transparent panel disposed at the front panel of said display unit,
• an image sensor disposed movably between said display unit and transparent panel for scanning the surface of said transparent panel,
• a lid unit substantially having at least the same size as the size of the display unit or substantially having at least the same size as the size of the reading area of the image sensor, and having tablet means disposed on said lid unit for writing with a writing tool including at least one of pencil and marker pen on a surface of the tablet means,
• wherein said lid unit is provided so as to be free to open or close to said main body unit, the surface of the tablet means is in contact with the transparent panel in a closed state, and said lid unit is mounted so that the surface of the tablet means coincides with the reading area of the image sensor.

An image sensor for scanning a surface of a transparent panel comprising:

• a lens member disposed so that an optical path of the lens member may be substantially parallel to said transparent panel surface,
• a prism member for bending an optical path of a light coming from a direction of the transparent panel so that one focal position of the lens member may be adjusted to the surface of said transparent panel, and that the light coming from the direction of the transparent panel may enter said lens member,
• a light sensor disposed at an other focal position of said lens member,
• said prism member made of a transparent material for lengthening the optical path to the image sensor,
• a light source for irradiating said transparent panel surface with light, and
• wherein said prism member, lens member and light sensor are arranged so that an optical path from said prism member to said light sensor is substantially parallel to said transparent panel surface.

• a transparent panel disposed at a front of said display unit,
• an image sensor disposed movably between said display unit and said transparent panel for scanning the surface of said transparent panel,
• said image sensor comprising a lens member disposed so that the optical path may be substantially parallel to said transparent panel surface, a prism member for bending the optical path so that a focal position of said lens member may be adjusted to the surface of said transparent panel and allow light coming from the direction of the transparent panel to enter said lens member, a light sensor disposed at an other focal position of said lens member, and a light source for irradiating said transparent panel surface with light, and
• roller means for moving a document, said roller means rotatably provided at one side vertical to the moving direction of the image sensor on the transparent panel surface,
• wherein said image sensor can stop at a position corresponding to the position of the roller means, and can read the moving document held between the transparent panel and roller means, and
• wherein said roller means possess rotation angle detecting means for detecting the angle of rotation of the roller, and said image sensor can read the document depending on the detected angle of rotation.
