Document Type and Number:
Japanese Patent JP2744968
Kind Code:
B2
Abstract:
An image sensing apparatus comprises: electro-optical conversion elements (11, 12, ..., 1n) arranged integrally in a row to constitute a line image sensor for effecting electro-optical conversion to produce respective bit image signals; switching elements (21, 22, ..., 2n) connected to the corresponding conversion elements and switchable between ON and OFF states to read out the corresponding respective bit image signals; a scanning circuit (3) for scanning sequentially the switching elements (21, 22, ..., 2n) sequentially to turn them ON thereby to effect the sequential reading of the bit image signals; an initiating signal generating circuit (4) connected to the scanning circuit (3) for generating an initiating signal effective to initiate the scanning circuit; an ending signal generating circuit (5) connected to the scanning circuit (3) and operative after the last switching element is turned OFF for generating an ending signal indicative of the ending of scanning operation; a control circuit (6) receptive of the initiating and ending signals to produce a control signal; and a switching circuit (7) switched according to the control signal to output the bit image signals.
