<p><P>PROBLEM TO BE SOLVED: To provide a detecting device of the degree of ripeness and the sugar content of fruits, which can prevent a light receiving sensor from detecting light in the outside world and can enhance the detection accuracy. <P>SOLUTION: The device detects the degree of ripeness and sugar content o fruits by projecting light from a light emitter 5 to a fruit A and detecting reflected light scattered and reflected in the fruit A using a light receiving sensor 6. The device supports the fruit A while closely contacting the fruit A onto its lower surface, is provided with an elastic receiving table 4 formed in its central portion an aperture 13, is mounted with the light receiving sensor 6 which faces to the aperture 13 of the elastic receiving table 4 and is enclosed on its periphery by a light shielding cylinder 16. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
