Abstract

PURPOSE:To shorten a time to detect the overlap of data by providing the number of recording areas which corresponds to the type of registering data, in advance and recording registration overlap information such as the number of times of registering of the respective registering data to these recording areas when the data are registered. CONSTITUTION:When the same data as the registered data are registered, an overlap information writing circuit 8 writes the information to show overlapped registration to the recording area of a memory which corresponds to the data. When detecting data are inputted to detect the overlap, an overlap information reading circuit 10 reads the information concerning the overlapped registration from the recording area of the memory to correspond to the detecting data. Thus, since the overlap count table reading circuit 10 which is activated when the overlap of the registering data is detected, only reads the data from the said area of an overlap count table 9, the time from the activation of the overlap detection for the registering data after the detecting data are inputted to the end of the detection for the number of times of overlapping is extremely shortened.

[Problem to be solved by the invention]

As described above, when detecting duplication of registered data in a conventional data processing device, it is necessary to read out all the data in the data table in which the registered data has been written and compare it point by point with the data for duplicate detection. There is a problem in that as the number of duplicates increases, it takes a long time to detect duplicates.

The present invention has been made to solve such problems, and an object of the present invention is to provide a data processing device that can detect duplicate registration of data in a short time.

[Means to solve the problem]

The data processing device of the present invention includes a memory defining a recording area for recording information regarding duplicate registration of each data corresponding to each piece of data to be registered; a duplicate information writing circuit that writes information indicating duplicate registration of the same data to a memory recording area corresponding to the memory, and a duplicate information writing circuit that reads information regarding duplicate registration from the memory recording area corresponding to the detected data input to detect duplication. It is characterized by comprising a readout circuit.

[Effect]

In the data processing device of the present invention, when the same data as already registered data is registered, the duplicate information writing circuit writes information indicating duplicate registration to the memory storage area corresponding to the data, and also detects the duplicate. When the detected data is input, the duplicate information reading circuit reads out information regarding duplicate registration from the memory storage area corresponding to the detected data.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on drawings showing embodiments thereof. FIG. 1 is a block diagram schematically showing the configuration of main parts of a data processing device according to the present invention, in which 1 is a registered data input having a buffer function for temporarily storing data inputted with a keyboard, etc. The circuit transfers the registration data stored by the registration data input circuit 1 to the registration data writing circuit 2.
Registered data table 3 prepared in advance in a predetermined area of memory
Write in the order of registration.

On the other hand, the memory is divided into a predetermined number of recording areas, and a duplication count table 9 for recording the number of duplications in each recording area is provided in advance in a predetermined area in the memory. The data is sent to the duplicate count table writing circuit 8, and every time data is registered, the duplicate count table writing circuit 8 searches the registered data table 3 to determine whether there is any overlap with registered data, and according to the determination result. Then, the number of registrations in the recording area of the duplication count table 9 corresponding to the data is updated.

In addition, data input using a keyboard or the like to detect duplication of registered data is temporarily stored in the buffer of the check data input circuit 7, and the check data input circuit 7 outputs this detected data to the duplication count table reading circuit 10. However, the duplication count table reading circuit 10 reads out the number of duplications recorded in the recording area of the duplication count table 9 corresponding to the given detection data, and returns the read count of duplications to the check data input circuit @7.

Next, a procedure for data registration and duplicate detection of registered data by the data processing apparatus configured as described above will be explained. In addition, the duplicate count table 9 has 100 registered data 0.
,1,2. . . , 99 are divided into 100 recording areas. Registration data input using a keyboard or the like is temporarily stored in the registration data input circuit 1, and the registration data writing circuit 2 sequentially registers it in the registration data table 3, while the duplicate count table writing circuit 8 registers the data each time the data is registered. , the registered data table 3 is searched to determine whether there is any overlap with registered data, and if there is no overlap, an initial value "0" is set in the recording area of the overlap count table 9 provided corresponding to this registered data. The number of duplicates recorded as "1" is set as "1", and if there is a duplicate, the number of duplicates in the recording area of the corresponding duplicate count table 9 is set as "1".
1" is added and updated. After the input of the registered data is completed, when detection data for detecting duplication of registered data is entered manually using a keyboard etc., the check data input circuit 7 temporarily checks the input detection data. Record, send this to the duplicate count table reading circuit IO, duplicate count 1
- The table reading circuit 10 reads the number of duplicates from the recording area of the duplicate count table 9 corresponding to the detected data, and returns the read number of duplicates as an answer signal to the check data input circuit 7, and the check data input circuit 7 receives the returned data. Notify the operator by displaying the number of duplicates.

Therefore, the duplicate count table reading circuit activated when detecting duplication of registered data only reads data from the corresponding recording area of the duplicate count table.
The time from when detection data is input and registration data duplication detection is activated until the detection of the number of duplications is completed is significantly shortened.

In addition, in this embodiment, the number of duplications is recorded in each recording area of the duplication count table, but when detecting the presence or absence of duplicate registration of each registered data, the presence or absence of duplication is set to "1" and "
It may also be recorded using two values: 0''.

〔Effect of the invention〕

The data processing device of the present invention provides a number of recording areas in advance according to the types of registered data, and records registration duplication information such as the number of registrations of each registered data in these recording areas at the time of data registration. Therefore, when detecting duplicate registration of data, it is only necessary to read out the duplicate information recorded in the corresponding recording area, which has the excellent effect of significantly shortening the time required to detect duplicates.
