Patent ID: 8099065

Claim:
A transmitting apparatus comprising a control section and an antenna driving section connecting to the control section, and transmitting an LF signal from the antenna by controlling the antenna driving section by the control section, the control section comprising: voltage control means for outputting a control signal based on a signal to be transmitted; and voltage supplying means for supplying a predetermined voltage to the antenna driving section for a predetermined period of time based on a control signal output from the voltage control means, the antenna driving section comprising: a transistor that outputs driving current to the antenna; and transistor driving control means for controlling the driving of the transistor based on the value of the voltage supplied from the voltage supplying means, wherein the control section is connected to the antenna driving section only by a first harness and a second harness, wherein the first harness connects the voltage supplying means and the transistor driving control means, and wherein the second harness connects a ground side of the voltage supplying means and a ground side of the transistor.
