<p><P>PROBLEM TO BE SOLVED: To provide a quality evaluation device of fruits and vegetables capable of avoiding error generation in internal quality information of a measuring object by acquiring light receiving information for quality evaluation in the proper state to the utmost by reducing the remaining charge in a light receiving sensor. <P>SOLUTION: This device is constituted so that the internal quality information of the measuring object M is acquired based on the light receiving information for quality evaluation acquired by receiving transmitted light from the measuring object M by the charge accumulation type light receiving sensor 23. The charge is accumulated in the light receiving sensor 23 from accumulation start timing until elapse of an accumulation setting time, and then a charge accumulation discharge processing for discharging the charge accumulated in the light receiving sensor 23 is executed repeatedly until elapse of a discharge setting time. When the measuring object M reaches a measuring spot, the accumulated charge is discharged, and then a measuring charge accumulation processing for accumulating the charge used for the light receiving information for quality evaluation is executed. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
