Abstract
An automatic code reading device, which is adaptable to use in object storage and retrieval apparatus, can read out the code mark affixed on an axial end surface of an object having a circular section. The device includes a housing defining a chamber in which the object should be loaded. In the housing, a read head unit for reading out the code mark and a holder for holding the drawn object are mounted. The read head unit or the holder is rotated by motor drive to scan the code mark affixed on the drawn object by the read head unit. The rotational angular extent is controlled (360°+α°), where α° is at least an angular extent over which the code mark extends.
The reading device is provided with a pick-up device for drawing object into the chamber and pushing out the object therefrom.
