ABSTRACT:
In an information transmitting device, a variable capacitor which is charged to have a predetermined voltage discharges through a predetermined resistor. Until the voltage becomes lower than a predetermined threshold voltage, the number of AC signals having a predetermined frequency is counted. Accordingly, first continuous amount information of a binary code corresponding to a writing pressure is obtained and is converted to a Gray code, which is regarded as second continuous amount information. A resonant circuit is opened or shorted in accordance with ‘0’ or ‘1’ in the second continuous amount information, so as to transmit the second continuous amount information.
