Input system including position-detecting device

An electronic device for drawing a picture, comprising:

• an operation panel configured to receive electromagnetic waves from a resonant circuit in an electronic position-pointing instrument having a pen-shaped housing manipulated on the operation panel by a user performing a drawing operation, the drawing operation comprising drawing a picture;
• a touch pad located at an interior and/or exterior of the operation panel and configured to detect a user's finger for performing a setting operation;
• and
• a control unit configured to detect the drawing operation performed by a first manipulation of location pointed to by the position-pointing instrument, the control unit further configured to detect the setting operation performed by a second manipulation by the user's finger using the touch pad and to distinguish the setting operation from the first manipulation of location pointed to by the position-pointing instrument, wherein the second manipulation using the touch pad is detectable to invoke the setting operation while the drawing operation using the position-pointing instrument is performed,
• wherein the control unit is configured to permit simultaneous implementation of the drawing operation and the setting operation,
• wherein the setting operation comprises at least zooming in and/or out.
