Abstract

PURPOSE:To improve the operability and the work efficiency by always displaying a cursor in a position of a field which is designated in advance first, even in case when a screen is changed due to a change of a record. CONSTITUTION:When a record which is displayed on a display part 3 is changed by operating an input means 1, a control part 2 allows a data reader 6 to read data of a record corresponding to a record number stored in a record register 5, from a main memory, and allows the reader to write said data in a data memory 4. Also, the control part 2 sends a field number stored in a field start register 9 to a field register 10 and allows it to store said field number, and moreover, allows a coordinate reader 7 to read a position coordinate corresponding to the field number stored in the field register 10, from the main memory. Subsequently, the control part 2 sends the position coordinate which has been read by the coordinate reader 7 to a cursor generating device 8, and displays a cursor in a position on a screen of the corresponding display part 3. In such a way, the cursor is displayed in a position of a field which is designated in advance.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data processing device, particularly a data processing device called a database.

[Conventional technology]

Although databases using data processing devices such as word processors and personal computers 8 have been put into practical use, so-called card-type databases aimed at more personal use have become widespread. This card-type database displays a card-like display on the screen of a display means such as a CRT display, in the same way that information was previously organized by writing various data on paper cards. , a collection of one unit of data, that is, records created by inputting various data into this, is stored as a large number of databases.

By the way, in such conventional card-type databases, as shown in Figure 3(a), one record (for example, a collection of data for one person in a directory) has multiple fields (for example, in a directory, a collection of data for one person). If available, the information for one person consists of name, age, address, and other individual data).

Conventionally, when a record is displayed and another record is displayed, as shown in FIGS. In other words, the configuration that appears in the name field (in the example in Figure 3) is common.Because of q, new data must be entered in fields other than the first field, for example in the age or address format in the example in Figure 3. You need to move the cursor if you want to change it.

On the other hand, there are also known card-type databases in which the field in which the cursor is located does not change even when a record is changed. However, in general, when data is entered in a certain field in a certain record, the cursor automatically moves to the next field.

[Problem to be solved by the invention]

Therefore, for example, if you want to input new information or change only the same field in multiple records one after another, as shown in Figure 4 (al), if you position the cursor on the age field in a certain record and input changes to it, ,
As shown in Figure 4 (C), the cursor moves to the next address field, so if you change the record here, the cursor moves from the address field to the age field as shown in Figure 4 (C). I need to bring it back. After W, it is necessary to repeat the operation of moving the cursor to the next higher field each time the record is changed.

The present invention was made in view of these circumstances, and
An object of the present invention is to provide a data processing device configured such that if a field is designated in advance, a cursor is automatically positioned at the designated field each time a record is changed.

[Means to solve the problem]

The data processing device of the present invention is configured to store a designated field inputted from an input means and to automatically position a cursor at the position of this field each time a record is changed.

The present invention provides a data memory that stores data in units of records made up of a plurality of fields, a display means that displays the data stored in the data memory,
A cursor position generating means for displaying a cursor on the display means, a coordinate reading means for giving the cursor position generating means a coordinate position at which the cursor on the display means should be displayed, and an input means for inputting data. a first field number storage means for storing a field number that is input from the input means and designates a field; second field number storage means that reads a field number stored in the storage means and provides the coordinate position of the field number to the coordinate reading means; and field data reading means for storing field data in a storage position of the data memory corresponding to the field number stored in the field number storage means.

[Operation] In the data processing device of the present invention, each time a record is changed, a cursor is displayed at a prespecified field position.

[Embodiments of the invention]

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 showing the configuration of a data processing apparatus according to the present invention.

In the figure, reference numeral 1 denotes input means such as a keyboard for inputting data, control signals, etc. Character codes, control signals, etc. generated by the operation of this input means 1 are given to a control section 2. The keyboard 1 also includes a field designation key for designating the position where the cursor is displayed and a record movement key for moving records.

The control section 2 is composed of a microprocessor, and operates as a control center for the entire apparatus of the present invention.

3 is a display section, for example a CRT display.

Alternatively, a liquid crystal panel or the like is used.

A data memory 4 stores data to be displayed on the display section 3. Data is supplied to this data memory 4 from a record data reader 6 and a field data reader 11, which will be described later.

The data memory 4 stores data given from the record data reader 6 and the field data reader 11, and this is displayed on the display section 3.

5 is a record register, to which data specifying a record, such as a record number, is given from the control unit 2;
Remember this.

Reference numeral 6 denotes a record data reader which, when given a predetermined command from the control unit 2, reads out the record number stored in the record register 5 and reads out the data of the corresponding record from the main memory (not shown). , is stored in the data memory 4.

Reference numeral 7 denotes a coordinate reader, which, when given the position coordinates of the cursor on the display screen of the display section 3, supplies them to the cursor generator. Further, when a predetermined signal is given from the control section 2, the position coordinates of the cursor are read out from a field register 1O, which will be described later, and given to the cursor generation device 8.

The cursor generator 8 displays a cursor at a position on the screen of the display unit 3 corresponding to the coordinate position given from the coordinate reader 7.

A field start register 9 serves as a first field number storage means, and when a field is designated by the operation of the input means 1, it stores data specifying the designated field, that is, the field number.

A field register 10 serves as a second field number storage means, and when a predetermined signal is given from the control section 2, the field number stored in the field start register 9 is read out and the field number is read out from the coordinate reader 7 and will be described later. The data is given to the field data reader 11 to be used.

The field data reader 11 reads data input or changed by operating the input means 1 and provides it to the data memory 4 . Therefore, the data memory 4 stores record data read from a main memory (not shown) by the record data reader 6 and displays it on the display section 3, and also when new data is given from the field data reader 11. Then, this is rewritten with the already stored data and displayed on the display section 3.

The operation of the data processing apparatus of the present invention having such a configuration will be explained with reference to the flowchart of FIG. 2 showing its processing procedure.

First, a field is specified by operating the input means 1, that is, a field in which the cursor should be positioned is specified by pressing a field specifying key (not shown) provided in the input means 1 (step l ), the control unit 2 stores the corresponding field number in the field start register 9 (step S2).

Next, input the record displayed on the display section 3 into the input means 1.
Change by operating. m+, when the next record to be displayed on the display unit 3 is specified by pressing a record movement key (not shown) provided in the input means 1, (
Step 3), the control unit 2 stores the corresponding record number in the record register 5 (step S4).

Then, the control unit 2 causes the record data reader 6 to read data of the record corresponding to the record number stored in the record register 5 from the main memory (not shown) and writes it into the data memory 4 (step S5).

Further, the control unit 2 sends the field number stored in the field start register 9 to the field register 10 for storage (step S6), and further sends the position coordinates stored in the field register IO to the coordinate reader 7 corresponding to the field number. is read from the main memory (step S7).

Then, the control unit 2 sends the position coordinates read by the coordinate reader 7 to the cursor generator 8, and displays a cursor at the corresponding position on the screen of the display unit 3 (step S8).

Through the above processing, regardless of the cursor position before the record was changed, if the record is changed and a new screen is displayed on the display unit 3, the cursor will be moved to the pre-specified field position. is displayed.

Next, when new or changed data is input by operating the input means I (step 9), the control unit 2 causes the field data reader 11 to read the data input from the input means 1 (step 31G). ), and further writes to the storage location of the data memory 4 corresponding to the field number stored in the field register 10, that is, the address of the data memory 4 where the data of the specified field is stored (step 5ll). The data is displayed on the display section 3.

Then, when the field movement key of the input means 1 is operated again, steps SL2 to S3. The process proceeds in the order of S4, and the same process as described above is repeated.

Therefore, after data is input into the specified field in step Sll, the cursor moves to the next field, but the record movement key is operated again and step 34. As the process progresses in the order of S5..., the field number stored in the field start register 9 is read again by the coordinate reader 7 and the corresponding position on the screen of the display section 3, that is, the field number that is specified, is read. The cursor reappears at the location.

〔Effect of the invention〕

As described in detail above, according to the data processing apparatus of the present invention, even when the screen is changed due to a change in a record, the cursor is always displayed at the position of the initially specified field. Therefore, when entering new data or changing data in the same field of multiple records, there is no need to move the cursor every time the record is changed and the screen changes (this improves operability and work efficiency. will improve.
