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]

By the way, the quality of fruits and vegetables differs from the fruits and vegetables in units of arrival, sales, cultivation place, cultivation time, and the like (hereinafter, may be abbreviated as different lots). And if it can be compared with the quality of fruits and vegetables that existed in the past, it will be effective in evaluating the quality of fruits and vegetables. For example, such a fruit and vegetable quality measuring device is installed near a fruit and vegetable counter in a supermarket or a fruit or vegetable display stand such as a fruit or vegetable store, and the consumer himself uses the quality measuring device to display the fruit and vegetable display stand. In some cases, it is possible to measure quality information of fruits and vegetables selected from. In such a case, if it is known how much the quality of the fruits and vegetables currently displayed is compared with the quality of the fruits and vegetables displayed in the past, for example, the day before or at the same time of the previous year, consumers can It is effective in selecting fruits and vegetables. However, in the conventional apparatus, since only the quality information measured by the measuring means is output, the quality of the measured fruits and vegetables is compared with the quality of fruits and vegetables that existed in the past in a different lot from the fruits and vegetables. It was hard to understand how big it was.

The present invention has been made in view of the above circumstances, and has as its object to compare the measured quality of fruits and vegetables with the quality of fruits and vegetables that are different from the fruits and lots and exist in the past. The purpose of the present invention is to be able to provide the information.

[0005]

According to the first aspect of the present invention, when the start is instructed by the instructing means, the representative information calculating means based on the quality information sequentially measured by the measuring means. When the representative information is obtained and the end is instructed by the command means, the representative information obtained by the representative information calculating means is stored in the storage means as past representative information. The output unit outputs the past representative information stored in the storage unit together with the quality information measured by the measurement unit. In other words, the past representative information is representative information that was obtained by the representative information calculating means when the end was commanded by the command means in the past before the measurement by the current measuring means, and the start of the command means. In addition, past end information can be obtained for fruits and vegetables whose lot is different from the fruits and vegetables to be measured by the end command.
Therefore, by comparing the quality information measured by the measuring means with the past representative information based on the output information of the output means, the quality of the measured fruits and vegetables differs from the fruits and vegetables by a lot and was present in the past. It can be compared relatively with the quality of fruits and vegetables. Moreover, not the quality information itself sequentially measured by the measuring means, but representative information of the quality information is output as past representative information, so that the quality of the measured fruits and vegetables and the fruits and vegetables differed in the lot and existed in the past. The comparison with the quality of fruits and vegetables can be made easily and clearly. In addition, since the representative information is updated based on the sequentially measured quality information, highly reliable past 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. In the past, for example,
It can be compared relatively with the quality of fruits and vegetables displayed on the previous day or the same period of the previous year.

According to the second aspect of the present invention, when the quality information measured by the measurement means and the past representative information stored in the storage means are output to the output means, The representative information obtained by the representative information calculating means at the time of output is output together as the current representative information. In other words, when the quality information is sequentially measured by the measuring means for a plurality of fruits and vegetables of the same lot, representative information is obtained based on the quality information sequentially measured in such a manner, and the quality information is output to the output means. Then, the representative information obtained by the representative information calculating means at that time is output together as the current representative information. That is, the current representative information indicates the state of the quality of the lot including the measured fruits and vegetables. Therefore, it is possible to relatively compare the measured quality of the fruits and vegetables, the quality of the fruits and vegetables existing in the lot different from the measured fruits and vegetables in the past, and the quality of the fruits and vegetables of the lot including the measured fruits and vegetables.

For example, when a quality measuring device is installed near a vegetable display stand so that the consumer can measure the quality information of the fruits and vegetables, the consumer is currently displayed on the basis of the output information of the output means. The quality of the fruits and vegetables currently displayed can be compared with the quality of the fruits and vegetables displayed in the past, for example, the day before or at the same time of the previous year, and the quality of the fruits and vegetables currently displayed Can be evaluated whether or not was selected.

According to the characteristic configuration of the third aspect, the past representative information and the current representative information are output to the representative information output means separate from the output means. In other words, 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 measurement means, the representative information output means can be used by anyone other than the consumer using the measurement means. It is possible to provide the consumer with past representative information that is representative information of the quality of the fruits and vegetables that were displayed in the past, and current representative information that is representative information of the quality of the fruits and vegetables that are currently displayed.

[0010] According to the characteristic configuration of the fourth aspect, a plurality of past representative information is output to the output means in association with the passage of time. Therefore, since the measured quality of the fruits and vegetables can be relatively compared with the quality of a plurality of past lots whose lots are different from the fruits and vegetables, the quality can be more accurately evaluated.

According to a fifth aspect 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 characteristic configuration 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. That is, the average value as the representative information indicates the average quality level of the lot of the fruits and vegetables to be measured.
Therefore, the quality information of the measured fruits and vegetables can be evaluated easily and clearly.

According to the characteristic configuration of the present invention, 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.
