Abstract
Various embodiments provide an electronic pen that ensures security of information, avoids of unnecessary transmission of information, and protects a core body. In one embodiment, the electronic pen includes a core body, a signal transmitter that transmits a signal to a sensor of a position detecting device, a protector that sets at least a tip of the core body to the state of being not exposed to an external environment, and a detector that detects whether or not at least the tip of the core body is in the state of being protected by the protector. A signal including information is allowed to be transmitted from the signal transmitter when at least the tip of the core body is not protected by the protector, and is precluded from being transmitted when at least the tip of the core body is protected by the protector.
