For example, a number is read at a position on the short distance side, and then a number plate is read at a position on the long distance side. Then, the second drive unit is operated to recognize the number plate, and the third and fourth drive are performed. This is a third license plate reading unit that performs the same operation on the unit.
[0023]
Next, the operation will be described. The first drive unit 43 electrically moves the neck of the first imaging unit 18 every one second, for example, so that the imaging area 19 and the second imaging area 39 are alternately and repeatedly photographed. The focus also operates so as to have a predetermined appropriate value. The same operation is performed for the second to fourth driving units.
[0024]
