Transmission device

The invention discloses a transmission device using a non-contact short distance wireless transmission mode, which is not affected by the size and the position of the terminal device. The transmission device comprises a display unit, a support unit and a communication unit. The display unit receives the display and indication input from the operator. The support unit supports and retains the device. At least one communication unit is positioned in proximity to the support unit, and the communication unit outputs electric wave for performing non-contact communication with the device on the transmission destination in a orthogonal direction and transmits the above content through the non-contact communication among the devices on the transmission destination.
