Abstract: A colorimetry device having a light source for irradiating light to a measured object, a cover part provided with a take-out port for taking out light diffused from the measured object, and a placing part on which the measured object is placed, the measured object being put between the cover part and the placing part, so as to effect the color measurement of the measured object. A hinge mechanism is provided, so that when the measured object is placed on the placing part and the cover part is in a closed state, a measurement space dividing section for defining a measurement space between the cover part and the placing part is provided. A measuring light may also be arranged to irradiate the rear face of the measured object.

Abstract: According to the present invention, there is provided a colorimetry device which when measuring color of a leaf of a plant, makes it possible to perform the measurement while leaving the plant as it is, without cutting off the leaf and damaging the plant. The colorimetry device comprises a light source for irradiating light to a measured object, a cover part provided with a take-out port for taking out light diffused from the measured object, and a placing part on which the measured object is placed, in which colorimetry device the measured object is put between the cover part and the placing part, so as to effect the color measurement of the measured object. In this case, the placing part and the cover part are connected with each other by a hinge mechanism in an openable and closable manner, so that when the measured object is placed on the placing part and the cover part is made to be in a closed state, a measurement space dividing section for defining a measurement space between the cover part and the placing part is provided. At this time, since a gap is formed between the measurement space dividing section and the measured object, inevitably causing light to leak from the outside, a function of correcting the effect of the external light is also provided. Moreover, measuring ligth is also arranged to be irradiated from the rear face of the measured object. Thereby, light transmitted through the measured object can be detected, enabling a more exact color measurement to be performed in consideration of transmission property of the measured object.
