ELECTRONIC PEN SYSTEM
First Claim
1. An electronic pen system comprising:
- an electronic pen;
a touch panel body having a touch surface on which a touch operation is performed by the electronic pen or by a finger;
a position detecting device that detects a touch position on the touch surface of the touch panel where the touch operation is performed; and
a controller that receives position detection information on the touch position from the position detecting device and determines whether the touch operation is performed by the electronic pen or by the finger,the electronic pen comprising;
a grip portion that is grippable by a user'"'"'s hand;
a pen tip portion that is pressed onto the touch surface by a touch operation of the electronic pen;
a touch condition detector that detects a touch of the pen tip portion with the touch surface;
a pen information transmitter that transmits predetermined pen information to the controller when the touch condition detector detects the touch of the pen tip portion with the touch surface; and
a connecting switch that electrically connects the pen tip portion and the grip portion so that the user'"'"'s hand is brought into electrical continuity with the pen tip portion through the grip portion when the touch condition detector detects the touch of the pen tip portion with the touch surface;
wherein the controller determines that the touch operation is performed by the electronic pen when the controller receives the position detection information from the position detecting device after receiving the pen information from the electronic pen, while the controller determines that the touch operation is performed by the finger when the controller receives the position detection information from the position detecting device without receiving the pen information from the electronic pen.

Abstract
An electronic pen transmits pen information to a controller corresponding to detection of a touch condition, and thereafter turns ON a connecting switch that disconnects electrical connection between the tip portion and the grip portion of the pen that are provided in a state of being electrically disconnected from each other so as to cause a pen input acceptance state. The controller determines that position detection information is from the electronic pen when the position detection information is received from a position detecting device after the pen information is received from the electronic pen, while the controller determines that position detection information is from a finger when the position detection information is received from the position detecting device without receiving the pen information from the electronic pen.

11. An electronic pen system comprising:
-
an electronic pen; a touch panel body having a touch surface on which a touch operation is performed by the electronic pen or by a finger; a position detecting device that detects a touch position on the touch surface of the touch panel where the touch operation is performed; and a controller that receives position detection information on the touch position from the position detecting device and determines whether the touch operation is performed by the electronic pen or by the finger, the controller comprising; a first controller that performs predetermined pen input processing corresponding to a touch operation by the electronic pen; and a second controller that performs predetermined finger input processing corresponding to a touch operation by a finger, wherein the controller concurrently performs the pen input processing of the first controller and the finger input processing of the second controller. - View Dependent Claims (12, 13, 14, 15)

16. An electronic pen system comprising:
-
a plurality of electronic pens, each of the electronic pens has identification information; a touch panel body having a touch surface on which a touch operation is performed by at least one of the electronic pens; a position detecting device that detects a touch position of at least one of the electronic pens on the touch surface; a display device that displays a predetermined image by using the touch surface as a display screen; and a controller that causes the display device to display an image corresponding to position detection information obtained by the position detecting device, wherein each of the electronic pens has a property selector that allows a user to select property information, and pen information including the property information selected by the property selector and the identification information of the each of the electronic pens is transmitted to the controller, and wherein the controller causes the display device to display an image corresponding to the property information obtained based on the pen information received from each electronic pen. - View Dependent Claims (17, 18, 19, 20)
