Abstract
Abstract A portable graphic computer apparatus is comprised of a tablet for inputting coordinates data, a detecting circuit for detecting the coordinates data inputted by the tablet, a video image data forming circuit for forming video image data corresponding to input coordinates based on the coordinates data by an output signal from the detecting circuit, a memory for storing the video image data, a video signal generating circuit for generating a video signal from the video image data, a sound source, a speaker connected to the sound source, an output circuit connected to the video signal generating circuit for outputting the video signal, and a cabinet for accommodating therein elements from the tablet to the speaker, wherein musical scale or sound volume of the sound source is varied by an output signal of the coordinates data detecting circuit.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
280 words
A portable graphic computer apparatus comprising: (a) a tablet for inputting coordinate data; (b) tracing means for performing a tracing motion on said tablet; (c) detecting means for detecting coordinate data inputted by tracing motion of said tracing means on said tablet; (d) video image data forming means connected to receive an output signal from said detecting means for forming video image data corresponding to input coordinates based on said coordinate data; (e) a memory connected to said video image data forming means for storing said video image data; (f) video signal generating means connected to said memory for generating a video signal from said video image data; (g) a sound source; (h) a speaker connected to said sound source; (i) output means connected to said video signal generating means for outputting said video signal; (j) a cabinet for enclosing at least said tablet and said detecting means, and said cabinet having an aperture aligned with a tracing area of said tablet for tracing said tracing area of said tablet, wherein a musical scale of said sound source is varied by a changing first output signal of said coordinate data detecting means, said changing first output signal being generated in response to movement of said tracing means in one direction relative to said tablet, and a sound volume of said sound source is varied by a changing second output signal of said coordinate data detecting means, said changing second output signal being generated in response to movement of said tracing means in a different direction from said one direction relative to said tablet; and (k) an executing switch for fixing video image data corresponding to movement of said tracing means.
Claim 2
Dependent Claim
280 words
A portable graphic computer apparatus comprising: (a) a tablet for inputting coordinate data; (b) tracing means for performing a tracing motion on said tablet; (c) detecting means for detecting coordinate data inputted by tracing motion of said tracing means on said tablet; (d) video image data forming means connected to receive an output signal from said detecting means for forming video image data corresponding to input coordinates based on said coordinate data; (e) a memory connected to said video image data forming means for storing said video image data; (f) video signal generating means connected to said memory for generating a video signal from said video image data; (g) a sound source; (h) a speaker connected to said sound source; (i) output means connected to said video signal generating means for outputting said video signal; (j) a cabinet for enclosing at least said tablet and said detecting means, and said cabinet having an aperture aligned with a tracing area of said tablet for tracing said tracing area of said tablet, wherein a musical scale of said sound source is varied by a changing first output signal of said coordinate data detecting means, said changing first output signal being generated in response to movement of said tracing means in one direction relative to said tablet, and a sound volume of said sound source is varied by a changing second output signal of said coordinate data detecting means, said changing second output signal being generated in response to movement of said tracing means in a different direction from said one direction relative to said tablet; and (k) an executing switch for fixing video image data corresponding to movement of said tracing means.
Claim 3
Dependent Claim
122 words
A portable graphic computer apparatus according to claim 1, wherein the sound volume of said sound source is successively changed in accordance with a change of input coordinates on said tablet in one axial direction, while the musical scale of said sound source is successively changed in accordance with a change of said input coordinates in the other axial direction, whereby said sound volume increases from a low volume to a high volume as said input coordinates change from one end to the opposite end in said one axial direction and the pitch of said sound increases from a low pitch to a high pitch as said input coordinates change from one end to the opposite end in said other axial direction.
Claim 4
Dependent Claim
39 words
A portable graphic computer apparatus according to claim 1 or 2, further comprising a sound button for selectively controlling said coordinate detecting means so that said sound source is driven by an output signal of said coordinate detecting means.
Claim 5
Dependent Claim
18 words
A portable graphic computer apparatus according to claim 3, wherein said sound button is provided on said cabinet.
Claim 6
Dependent Claim
30 words
A portable graphic computer apparatus according to claim 1, wherein said cabinet has formed at peripheral portions thereof on said cabinet means for mounting a tracing sheet on said tablet.
