Abstract
Abstract An image input apparatus is disclosed, which comprises a running roller (26) manually rolled along an image information surface (P d ) for the scanning thereof, position detecting means (30) for detecting the position of the running roller according to the rotation thereof, a line sensor (25) for reading out image information of the image information surface, a line sensor driving circuit for driving the line sensor according to a control pulse signal having a constant cycle period, and memory means for storing the output of the line sensor. The output of the position detecting means (30) is utilized as address data of a memory to accurately store image information in the memory.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
132 words
An image input apparatus comprising : a housing (10); a light source (21) provided within said housing for illuminating an object surface; a roller (26,27) rotatably supported by said housing so as to contact with said object surface; position detecting means (30) operatively coupled with said roller for detecting a rotation thereof; a line sensor (25) provided within said housing for reading image information of said object surface according to light provided from said light source and reflected by said image information surface; a line sensor driving circuit (51) for driving said line sensor; and memory means (53) for storing a first output signal from said line sensor in accordance with a second output signal from said position detecting means representing the position of image information signal stored in said memory means.
Claim 2
Dependent Claim
24 words
The image input apparatus according to claim 1, wherein said position detecting means comprises detecting means (31,32,33) for detecting the rotation of said roller.
Claim 3
Dependent Claim
30 words
The image input apparatus according to claim 2, wherein said position detecting means includes a slit disk (31) mounted on the shaft of said roller and a rotation detector (32,33).
Claim 4
Dependent Claim
35 words
The image input apparatus according to claim 1, wherein light provided from said light source (21) and reflected by said image information surface is focused onto said line sensor (25) through a lens array (24).
Claim 5
Dependent Claim
100 words
The image input apparatus according to claim 1, wherein said line sensor driving circuit (51) is a first pulse generator for generating control pulses, said position detecting means (30) is a second pulse generator for generating pulses according to the rotation of said roller, and means are provided for selectively passing a pulse from one of said pulse generators when a plurality of pulses are provided from said one pulse generator during the pulse cycle period of the other pulse generator, the image information signal from said line sensor being thereby stored in a compressed form in said memory means.
