Hand-held copying apparatus

Claim 2

A hand-held copying apparatus comprising: reading means for reading in image information; storing means for storing and recalling image information read in by said reading means; and recording means for copying image information recalled from said storing means onto a copy paper by moving the apparatus manually so that said recording means is moved at a moving speed relative to the copy paper, said recording means including detecting means for detecting the moving speed of said recording means relative to the copy paper, a thermal head having thermal elements which are driven by driving pulses supplied thereto corresponding to said image information recalled from said storing means, and control means responsive to the moving speed detected by said detecting means for supplying said driving pulses to said thermal head which are of narrower pulse width when the moving speed is detected to be relatively higher, and of wider pulse width when the moving speed is detected to be relatively lower.

Claim 3

A hand-held copying apparatus according to claim 1, wherein said control means supplies said driving pulses having a pulse width which varies in proportion to the moving speed between an upper value and a lower value, and having a pulse width corresponding to said upper value and said lower value when the moving speed is above and below said values, respectively.

Claim 4

A hand-held copying apparatus according to claim 1, wherein said control means further controls the operation of said reading means for reading in image information, and further comprising mode transfer means for switching said control means between controlling said reading means and said recording means.

Claim 5

A hand-held copying apparatus comprising: reading means for reading in image information; storing means for storing and recalling image information read in by said reading means; and recording means for copying image information recalled from said storing means onto a copy paper by moving the apparatus manually so that said recording means is moved at a moving speed relative to the copy paper, said recording means including a recording portion and detecting means for detecting the moving speed of said recording portion relative to the copy paper; wherein said apparatus has a main body having a bottom portion provided with a pair of rollers which are spaced apart and axially in parallel with each other, said reading means includes a reading portion provided at a leading end of said bottom portion outwardly of one of said pair of rollers, said recording portion is disposed between said pair of rollers, and the one roller disposed between said reading portion and said recording portion provides a moving speed signal to said detecting means when said roller is moved over the surface of the copy paper.

Claim 6

A hand-held copying apparatus comprising: reading means for reading in image information; storing means for storing and recalling image information read in by said reading means; and recording means for copying image information recalled from said storing means onto a copy paper by moving the apparatus manually so that said recording means is moved at a moving speed relative to the copy paper, said recording means including a recording portion and detecting means for detecting the moving speed of said recording portion relative to the copy paper; wherein said apparatus has a main body having a bottom portion provided with a pair of rollers which are spaced apart and axially in parallel with each other, said reading means includes a reading portion provided at a leading end of said bottom portion outwardly of one of said pair of rollers, said recording portion is disposed between said pair of rollers, and the one roller disposed between said reading portion and said recording portion provides a moving speed signal to said detecting means when said roller is moved over the surface of the copy paper.

Claim 7

A hand-held copying apparatus according to claim 4, wherein said reading portion includes a reading window on the leading end of the bottom portion of the apparatus, said pair of rollers define a reference plane movable over an original surface to be read, and said reading means includes an image sensor having an optical axis in alignment with said reading window which is inclined at an angle to a vertical line perpendicular to the reference plane.

Claim 8

A hand-held copying apparatus according to claim 4, wherein said recording means includes means for withdrawing said recording portion into the main body of the apparatus when it is not in use.

Claim 9

A hand-held copying apparatus according to claim 4, further comprising an ink ribbon wound on supply and take-up reels and provided movably over said recording portion, wherein said take-up reel is drivingly connected to the other of said pair of rollers to wind said ink ribbon as said recording means is moved over the copy paper.

Claim 10

A hand-held copying apparatus comprising: reading means for reading in image information; storing means for storing and recalling image information read in by said reading means; and recording means for copying image information recalled from said storing means onto a copy paper by moving the apparatus manually so that said recording means is moved at a moving speed relative to the copy paper, said recording means including detecting means for detecting the moving speed of said recording means relative to the copy paper, a thermal head having thermal elements in a line which are driven by driving pulses supplied thereto to record image information recalled from said storing means on the copy paper in lines spaced at a timing interval, and control means responsive to the moving speed detected by said detecting means for supplying said driving pulses to said thermal head at a timing interval corresponding to the moving speed, wherein said driving pulses are of narrower pulse width when the timing interval is relatively narrow, and of wider pulse width when the timing interval is relatively wide.

Claim 11

A hand-held copying apparatus comprising: reading means for reading in image information; storing means for storing and recalling image information read in by said reading means; and recording means for copying image information recalled from said storing means onto a copy paper by moving the apparatus manually so that said recording means is moved at a moving speed relative to the copy paper, said recording means including detecting means for detecting the moving speed of said recording means relative to the copy paper, a thermal head having thermal elements in a line which are driven by driving pulses supplied thereto to record image information recalled from said storing means on the copy paper in lines spaced at a timing interval, and control means responsive to the moving speed detected by said detecting means for supplying said driving pulses to said thermal head at a timing interval corresponding to the moving speed, wherein said driving pulses are of narrower pulse width when the timing interval is relatively narrow, and of wider pulse width when the timing interval is relatively wide.
