Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
70 words
A coordinates input device comprising: vibration generation means for generating vibration; a vibration pen adapted to vibrate at an end thereof in response to the vibration generated by said vibration generation means and transmitted to the pen; and a vibration transmission plate having a roughened abutment surface presented to the vibration pen for reducing a surface wave component in order to eliminate the surface wave component of the transmitted vibration.
Claim 2
Dependent Claim
70 words
A coordinates input device comprising: vibration generation means for generating vibration; a vibration pen adapted to vibrate at an end thereof in response to the vibration generated by said vibration generation means and transmitted to the pen; and a vibration transmission plate having a roughened abutment surface presented to the vibration pen for reducing a surface wave component in order to eliminate the surface wave component of the transmitted vibration.
Claim 3
Dependent Claim
32 words
A coordinates input device according to claim 1 further comprising a sensor arranged on the roughened surface of the vibration transmission plate for detecting the vibration transmitted through said vibration transmission plate.
Claim 4
Dependent Claim
33 words
A coordinates input device according to claim 2 further comprising operation means for calculating an abutment position of said vibration pen based on a detection time of the vibration detected by said sensor.
Claim 5
Dependent Claim
21 words
A coordinates input device according to claim 1 further comprising a display provided on an underside of said vibration transmission plate.
Claim 6
Dependent Claim
71 words
A coordinates input device comprising: vibration generation means for generating vibration; a vibration pen adapted to vibrate at an end thereof in response to the vibration generated by said vibration generation means and transmitted to the pen; and a vibration transmission plate having a resin layer formed on a pen abutment surface thereof for absorbing a surface wave component in order to eliminate the surface wave component of the transmitted vibration.
Claim 7
Dependent Claim
71 words
A coordinates input device comprising: vibration generation means for generating vibration; a vibration pen adapted to vibrate at an end thereof in response to the vibration generated by said vibration generation means and transmitted to the pen; and a vibration transmission plate having a resin layer formed on a pen abutment surface thereof for absorbing a surface wave component in order to eliminate the surface wave component of the transmitted vibration.
Claim 8
Dependent Claim
27 words
A coordinates input device according to claim 5 further comprising a sensor arranged on the surface having the resin layer formed thereon of said vibration transmission plate.
Claim 9
Dependent Claim
33 words
A coordinates input device according to claim 6 further comprising operation means for calculating an abutment position of said vibration pen based on a detection time of the vibration detected by said sensor.
Claim 10
Dependent Claim
21 words
A coordinates input device according to claim 5 further comprising a display provided on an underside of said vibration transmission plate.
