Abstract
Abstract The data processing device for reading and processing visually observable information taking place on a data carrier includes a hand operated reading unit guidable in a first direction along a line of the text on the data carrier; scanning unit in the form of a column of photoelectric elements is arranged in the reading unit in a direction perpendicular to the direction of movement of the reading unit; and timing means provided in the reading unit for controlling the scanning rate of respective elements in response to the speed of movement of the reading unit.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
171 words
A data processing device for picking up and processing visually observable data present on a data carrier, comprising a hand operated reading unit guidable in a first direction over the data on said carrier; scanning means provided in said reading unit for scanning point-by-point the data on said carrier in a second direction which is perpendicular to said first direction; timing means arranged for controlling the time of successive scanning operation in said second direction in dependence on the speed of said reading unit relative to said data carrier in said first direction; said scanning means including a matrix of photoelectric elements extending in said second direction and cooperating with said timing means; said timing means including a displacement detector for measuring the displacement of said reading means relative to said data carrier; and said displacement detector includes a sectional roller supported for rotation in said reading unit and being engageable with said data carrier and means for generating a control signal proportional to the instant speed of said sectional roller.
Claim 2
Dependent Claim
171 words
A data processing device for picking up and processing visually observable data present on a data carrier, comprising a hand operated reading unit guidable in a first direction over the data on said carrier; scanning means provided in said reading unit for scanning point-by-point the data on said carrier in a second direction which is perpendicular to said first direction; timing means arranged for controlling the time of successive scanning operation in said second direction in dependence on the speed of said reading unit relative to said data carrier in said first direction; said scanning means including a matrix of photoelectric elements extending in said second direction and cooperating with said timing means; said timing means including a displacement detector for measuring the displacement of said reading means relative to said data carrier; and said displacement detector includes a sectional roller supported for rotation in said reading unit and being engageable with said data carrier and means for generating a control signal proportional to the instant speed of said sectional roller.
Claim 3
Dependent Claim
24 words
A data processing device as defined in claim 1, further including a reproduction unit coupled to said array of photodiodes by a flexible cable.
Claim 4
Dependent Claim
28 words
A data processing device as defined in claim 2, wherein said reproduction unit includes a monitor provided with a cathode ray tube display unit and/or a copying apparatus.
Claim 5
Dependent Claim
43 words
A data processing device as defined in claim 3, further including data storing means coupled between said reading unit and said reproduction device for successively storing the scanned information and for feeding the stored information at a fixed rate to said reproduction unit.
