The operation command buttons arranged around the panel need to be touched again with the panel operation stylus pen to switch them, and the movement range of the panel operation stylus pen is wide and the operation is complicated.

  Thus, various ideas have been made for an input operation method for an operation screen and a stylus pen for panel operation. For example, Japanese Patent Laid-Open No. 10-171586 (Patent Document 1) has been proposed.

  This patent document 1 uses a conductive material having elasticity at the contact point of the pen, changes the contact area when the contact point is pressed against the input tablet, and calculates the pen's current from the sum of the current values flowing through the contact point. This is a pen input device having a configuration for calculating writing pressure information, and can be used by changing the writing pressure information of the pen and switching the operation without using a pressure sensor or the like.

  Another proposal is JP-A-11-203034 (Patent Document 2).

  This patent document 2 is an electronic pen that inputs and inputs predetermined information to a host device. A pen tip that protrudes from the tip of the pen housing is movable along the longitudinal direction of the pen housing.

  Furthermore, Japanese Patent Application Laid-Open No. 2004-280745 (Patent Document 3) has been proposed as another configuration.

In this patent document 3, on the display screen such as a map, when an area to be enlarged is touched with a finger or a stylus pen and a circle is drawn and surrounded, the operation detection unit detects it, and based on this detection, the display control unit This is a display device that switches to enlarged display so that the area fits on the screen, and can be displayed at a desired enlargement rate in a single operation.
