Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fruit and vegetable quality measuring device provided with measuring means for measuring quality information of fruits and vegetables and output means for outputting the quality information measured by the measuring means.

[0002]

2. Description of the Related Art In such an apparatus for measuring the quality of fruits and vegetables,
Conventionally, only the quality information measured by the measuring means is output to the output means.

[0003]

However, if only the quality information measured by the measuring means is output only,
It is difficult to understand how much the output quality information is, and there is room for improvement in providing information that can relatively compare the measured quality information. For example, such a fruit and vegetable quality measuring device is installed near a fruit and vegetable counter in a supermarket, a display stand for fruits and vegetables such as a fruit and vegetable store, and the consumer himself uses the quality measuring device.
In some cases, it is possible to measure quality information of fruits and vegetables selected from a vegetable and vegetable display stand. In such a case, if only the quality information of the selected fruits and vegetables is output only, how much quality can be selected from the displayed fruits and vegetables, or how much the taste was according to one's own preference It's hard to tell if you can choose one.

The present invention has been made in view of such circumstances, and has as its object to provide information for relatively comparing the measured quality of fruits and vegetables with the quality of fruits and vegetables measured before the measurement. The object of the present invention is to provide an apparatus for measuring the quality of fruits and vegetables which can provide the following.

[0005]

According to the first aspect of the present invention, the representative information is obtained by the representative information calculating means based on the quality information sequentially measured by the measuring means. The representative information calculated by the representative information calculating means is output together with the quality information measured by the measuring means. Therefore, by comparing the quality information measured by the measuring means and the representative information based on the output information of the output means, the quality of the measured fruits and vegetables and the quality of the fruits and vegetables measured before the measurement are compared. Can be relatively compared. Moreover, instead of outputting the quality information itself sequentially measured by the measuring means, representative information of the quality information is output, so that the quality of the measured fruits and vegetables and the quality of the fruits and vegetables measured before the measurement are obtained. Comparison with
It can be done easily and clearly. Further, since the representative information is updated based on the sequentially measured quality information, highly reliable representative information can be provided.

[0006] For example, when a quality measuring device is installed near a display stand for fruits and vegetables so that the consumer can measure the quality information of the fruits and vegetables, the consumer selects the quality measurement device based on the output information of the output means. By comparing the quality information of the fruits and vegetables with the representative information, it is possible to select the quality of the fruits and vegetables displayed on the display, or the quality of the selections that match the taste of the user. Can be evaluated. Therefore, when a consumer purchases fruits and vegetables, it is possible to provide effective information for selecting fruits and vegetables having a desired quality. Moreover, since the representative information is calculated by the representative information calculating means based on the quality information sequentially measured by the consumer using the measuring means, the representative information can be obtained or updated by the seller. Or troublesome.

According to a second feature of the present invention, a plurality of measuring means are provided for measuring quality information of one kind of fruits and vegetables, and one output means is associated with each measuring means. Are provided, and the representative information calculation means is configured to obtain the representative information based on the measurement information of the plurality of measurement means, so that each output means has a measurement means corresponding to each output means. The same representative information is output together with the measured quality information. Therefore, since the representative information is obtained based on a larger number of quality information, the reliability of the representative information is further improved. In addition, it is possible to prevent a problem that the representative information output to each output unit is different despite the fact that the representative information is provided for fruits and vegetables of the same kind.

According to the third aspect of the present invention, an average value is obtained as representative information by the representative information calculating means based on the quality information sequentially measured by the measuring means, and the average value is output to the output means. Is output. For example, if the quality measuring device is installed near the display stand of fruits and vegetables so that consumers can measure the quality information of fruits and vegetables, the average value output to the output means is the average quality of the fruits and vegetables displayed. Will show the level. Therefore, the consumer can evaluate the quality information of the fruits and vegetables selected by himself / herself by comparing it with the average quality level of the fruits and vegetables displayed, so that it is easy to determine whether or not a high-quality one has been selected. Can be determined.

According to the characteristic configuration of the present invention, among the quality information sequentially measured by the measuring means, the representative information calculating means sequentially sets, as representative information, a set number of pieces of information indicating that the quality is good. The quality information is obtained, and the quality information of the upper set number having a good quality thus obtained is output to the output means. Therefore, for example, if the quality measuring device is installed near the display stand of fruits and vegetables so that the consumer can measure the quality information of the fruits and vegetables, the consumer can select the top-ranking high-quality fruits and vegetables. It can be easily determined whether or not.

According to the characteristic configuration of the present invention, the representative information is also output to the representative information output means separate from the output means. Therefore, if the representative information output means is installed at a place where the output information can be distinguished from consumers other than the consumer using the measuring means, the representative information output means can be used for consumers other than the consumers using the measuring means. The consumer can be provided with representative information on the quality of the fruits and vegetables being displayed.

[0011] According to the characteristic configuration of the sixth aspect, the measuring means irradiates the measuring light beam to the fruits and vegetables to obtain a spectrum of light reflected or transmitted from the fruits and vegetables and obtains a spectrum based on the obtained spectrum. And a spectrometer for obtaining quality information. When a measuring light beam is irradiated on fruits and vegetables,
The emitted light is absorbed according to the quality information of each component in a wavelength range specific to each component of the fruit or vegetable, so that a spectrum of reflected light or transmitted light from the fruit or vegetable is obtained, and based on the obtained spectrum. In addition, quality information can be obtained for each component of fruits and vegetables. Therefore, since the quality information based on the components of the fruits and vegetables can be measured by a non-destructive and simple operation, if the spectroscopic analyzer is applied as a specific configuration of the measuring means, it is intended for the operation by the consumer, and It is effective in providing effective quality information for selection.
