1. A handwriting input device comprising:
a display section which includes a display surface and which, in operation, displays handwritten input information that is handwritten on the display surface;
a position detection sensor which is disposed such that a position detection area of the position detection sensor is superimposed on a display area of the display surface and which, in operation, detects a position corresponding to the handwritten input information;
a memory which, in operation, stores electronic data according to the position that corresponds to the handwritten input information and that has been detected by the position detection sensor;
a transmission circuit which, in operation, transmits the electronic data stored in the memory to an external device; and
a control circuit which, in operation, controls the transmission of the electronic data stored in the memory to the external device via the transmission circuit,
wherein the display section, in response to a handwritten input operation performed on the display surface, displays the handwritten input information on the display surface, and
the control circuit, in response to receiving a predetermined operation by the user to visually erase the handwritten input information displayed on the display surface,
check whether or not the transmission to the external device via the transmission circuit is possible,
responsive to determining the transmission to the external device is possible, transmit the electronic data stored in the memory to the external device via the transmission circuit and erase the electronic data from the memory after the transmission, and
responsive to determining that the transmission to the external device is not possible, disable erasing of the electronic data from the memory.
