ABSTRACT:
A method for controlling information recognizing operation in which detecting an object, scanning the information recorded on the object and recognizing the scanned information are accomplished sequentially during the transfer of the object. While the object recorded with a code information thereon is transferred to face a scanning device, a detecting device detects existence of the object first and then the scanning device repeats to scan the code of the object. A data control device, rendered operative during object detecting operation of the detecting device, generates a timer signal having a constant time period within which a data processing device is allowed to recognize the input data applied from the scanning device. Setting the constant time period of the timer signal to be nearly equal to or shorter than the time period in which the object faces the scanning device, information recognizing operation is attained correctly per each object even when a plurality of objects are transferred with the tail of one object contacting with the head of the other object.
