Reading device, computer program product and reading system
First Claim
1. A reading device for repeatedly reading data, which is stored in a recording medium existing in an area where communication between the recording medium and the reading device can be established, in a noncontact method, comprising:
- a first generation unit for generating time series data which shows a result of reading in chronologic order;
a second generation unit for generating feature data indicative of a feature of the result of reading based on the time series data generated by the first generation unit;
a first sorting unit for sorting read data as necessary data or unnecessary data based on the feature data generated by the second generation unit,wherein the second generation unit extracts continuous reading numbers of successful continuous reading in chronologic order per recording medium, extracts a maximum continuous reading number from the extracted continuous reading numbers, and generates a continuous reading ratio by dividing the continuous reading numbers per recording medium according to the maximum continuous reading number, andthe first sorting unit sorts the data read from the recording medium as necessary data when the continuous reading ratio is within a range of threshold, and sorts the data read from the recording medium as unnecessary data when the continuous reading ratio is less than the threshold.

Abstract
The reader/writer repeatedly reads data, which is stored in an IC tag existing in an area where communication with the reader/writer can be established, from the IC tag in a noncontact method. The reader/writer transmits the read data to the administrative device. The administrative device generates read data which shows the result of reading in chronologic order and generates feature data indicative of the feature of the result of reading on the basis of the generated time series data. An IC tag is sorted as a target tag or an unnecessary tag by sorting the read data as necessary data or unnecessary data on the basis of the generated feature data.

7. A non-transitory computer program product for causing a computer to repeatedly read data, which is stored in a recording medium existing in an area where communication between the recording medium and the computer can be established, in a noncontact method, comprising:
-
a first generation step of generating time series data which shows a result of reading in chronologic order; a second generation step of generating feature data indicative of a feature of the result of reading based on the time series data generated in the first generation step; and a first sorting step of sorting read data as necessary data or unnecessary data based on the feature data generated in the second generation step; wherein the second generation step extracts continuous reading numbers of successful continuous reading in chronologic order per recording medium, extracts a maximum continuous reading number from the extracted continuous reading numbers, and generates a continuous reading ratio by dividing the continuous reading numbers per recording medium according to the maximum continuous reading number, and the first sorting step sorts the data read from the recording medium as necessary data when the continuous reading ratio is within a range of threshold, and sorts the data read from the recording medium as unnecessary data when the continuous reading ratio is less than the threshold. - View Dependent Claims (8, 9)
