Abstract
Abstract This invention relates to a handy sketching apparatus which has an image information reading function and a sketching function to draw an image on the basis of the image information read by the image information reading function, and which is easy to operate and easy to be miniaturized for smaller size. The handy sketching apparatus comprises a base block containing a progressive scanning image information reading mechanism through the bottom face, a sheet carrying path provided on the top side of the base block so as to carry a sheet in a specified direction substantially parallel to the bottom face of the base block, and an upper block integrally formed on the top side of the base block, straddling the sheet carrying path. The image information reading mechanism reads image information placed under the base block sequentially as the apparatus is moved in a sub-scanning direction. The upper block houses a traveling mechanism which is run back and forth in a main scanning direction across the sheet carrying path, thereby moving a drawing utensil to draw an image on the sheet on the sheet carrying path, on the basis of the image information read by the image information reading mechanism.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
145 words
A handy sketching apparatus comprising: (a) a base block which contains an image information reading mechanism for reading, through a bottom face, image information, placed under the base block, sequentially as the apparatus is moved in a sub-scanning direction; and (b) an upper block which is integrally formed on the top side of the base block, straddling a sheet carrying path provided on a top surface of the base block, the upper block containing a traveling mechanism which is run back and forth in a main scanning direction across the sheet carrying path, thereby moving a drawing utensil to draw an image on a sheet on the basis of the image information read by the image information reading mechanism, said sheet being carried back and forth on the sheet carrying path in a specified direction substantially parallel to the bottom face of the base block.
Claim 2
Dependent Claim
145 words
A handy sketching apparatus comprising: (a) a base block which contains an image information reading mechanism for reading, through a bottom face, image information, placed under the base block, sequentially as the apparatus is moved in a sub-scanning direction; and (b) an upper block which is integrally formed on the top side of the base block, straddling a sheet carrying path provided on a top surface of the base block, the upper block containing a traveling mechanism which is run back and forth in a main scanning direction across the sheet carrying path, thereby moving a drawing utensil to draw an image on a sheet on the basis of the image information read by the image information reading mechanism, said sheet being carried back and forth on the sheet carrying path in a specified direction substantially parallel to the bottom face of the base block.
Claim 3
Dependent Claim
110 words
A handy sketching apparatus as described in claim 1 wherein said image information reading mechanism comprises: (a) an optical system for projecting the image information read through the bottom face of the base block, (b) an image sensor for temporarily storing the image information projected by the optical system sequentially as the apparatus is moved in the sub-scanning direction, and (c) a moving amount detector for detecting the moving length of the apparatus in the sub-scanning direction, thus permitting the image information reading mechanism to write in a memory the image information which is temporarily stored in the image sensor sequentially in proportion to the moving length of the apparatus.
Claim 4
Dependent Claim
80 words
A handy sketching apparatus as described in claim 1 or 2 wherein said traveling mechanism comprises: (a) a carriage for holding the drawing utensil so as to enable a move up and down, (b) a guide shaft means for guiding the carriage in the main scanning direction, and (c) a belt engaged with the carriage and driven by a motive power so as to move the carriage back and forth along the guide shaft means in the main scanning direction.
Claim 5
Dependent Claim
55 words
A handy sketching apparatus as described in claim 3, further comprising: (a) a driving wheel rotated by means of a motive power, and (b) a driven wheel facing said driving wheel(s), so that the sheet is carried back and forth in a specified direction as it is clamped between said driving wheel and driven wheel(s).
Claim 6
Dependent Claim
24 words
A handy sketching apparatus as described in claim 4 wherein said specified direction is the direction in which the apparatus reads the image information.
Claim 7
Dependent Claim
52 words
A handy sketching apparatus as described in claim 5 wherein said motive power for driving the belt is a first motor and said motive power for rotating the driving wheel is a second motor, the first and second motors being arranged on a right and left side across the sheet carrying path.
Claim 8
Dependent Claim
36 words
A handy sketching apparatus as described in claim 1, 2, 4, 5 or 6 wherein a slit is formed between said base block and said upper block at a position corresponding to said sheet carrying path.
Claim 9
Dependent Claim
38 words
A handy sketching apparatus as described in claim 1, 2, 4, 5 or 6 wherein said base block is provided with an inspection window through which to view the image information placed under the base block from above.
Claim 10
Dependent Claim
33 words
A handy sketching apparatus as described in claim 1, 2, 4, 5 or 6 wherein said upper block is provided with a grip by which to move the apparatus in the sub-scanning direction.
Claim 11
Dependent Claim
26 words
A handy sketching apparatus as described in claim 1, 2, 4, 5 or 6 wherein said drawing utensil is a cutting pen or a writing pen.
