TRANSMISSION APPARATUS FOR REMOTELY INDICATING POSITION AND RECEPTION APPARATUS
First Claim
1. A transmitting apparatus for remotely indicating a position of a plane provided in a receiving apparatus, comprising:
- a button switch input unit including a button switch;
a slope sensor measuring a slope of the transmitting apparatus with respect to a gravity axis; and
two or more transmitters transmitting waveforms for transmitting positional information signals having different phases and the same frequency to the receiving apparatus so as to acquire positional information from the shift of the phase which is received by the receiving apparatus and shifted from a reference signal,wherein slope value information measured by the slope sensor is included in the waveform.

Abstract
A transmitting apparatus and receiving apparatus for indicating a position can be remotely controlled. The transmitting apparatus includes a means for measuring an inclined angle of a transmitter with respect to a gravity axis of the earth to measure and transmit the inclined value of the transmitter in addition to transmitting waveforms having different phase angles and the same frequency simultaneously and the receiving apparatus is configured by a receiving apparatus that receives and ultimately amplifies the transmitted signal and processes the amplified signal so as to acquire positional information regarding a shift of a phase which is shifted from a reference signal.

6. A receiving apparatus for remotely indicating a position which receives waveforms for transmitting positional information from a transmitting apparatus to indicate a position on a plane,
wherein the receiving apparatus receives waveforms for transmitting positional information signals having different phases and the same frequency from the transmitting apparatus and acquires positional information from a shift of a phase shifted from a reference signal and then displays the position on the plane, and wherein the receiving apparatus extracts a slope value of the transmitting apparatus with respect to a gravity axis included in the waveforms for transmitting the positional information signals and thereafter, and corrects a coordinate of the positional information depending on a slope.
