Abstract

PURPOSE:To improve the operability of a keyboard device by producing plural pieces of the same data through operations of keys. CONSTITUTION:A keyboard device main body 1 contains key switches 3-1, ten- key 3-3, etc. together with a definition key 3-2 used when the number of zeros generated with operation of a zero input key 3-4 and a display device for zero number. This keyboard device produces the key code operated through a key data generating part 4 with operation of keys 3. This produced key code is stored in a memory part 7 and at the same time the number which prescribes the number of produced zeros in a counter area 6-1 of a RAM6. The display data on the number of generated zeros is stored in a display part 8. Thus zeros are produced in the number equal to those stored in the counter area within the RAM6 with operation of a zero key 3-2. These generated zeros are stored in a key code memory part 7. It is also available to set data other than zero.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a keyboard device for inputting data into an electronic A1 calculator or data processing device through key operations.

[Prior Art] Conventionally, in electronic computers and data processing devices, in order to input multiple zero data with one key operation, the 2-zero key (lIEln key) and the 3-in-zero key (1-cho η key) have been used to input multiple zero data with one key operation. It was located in the department.

Although there are various requirements for setting the number of zeros in a multiple zero key depending on the environment in which this type of device is used, only a 2-zero key or a 3-zero key is fixedly provided.

It had become an inconvenience.

[Objective] The present invention eliminates the above-mentioned drawbacks by providing a keyboard device that allows a user to generate the same number of data as desired.

[Example] The present invention will be described in detail below with reference to the drawings.

FIG. 1 is a top view of the keyboard device to which the present invention is applied, l is the main body of the keyboard device, a part of which is
S key switch 3-1 and numeric keypad 3-3 from 0 to 9
is provided. 3-4 is a zero input key, and by operating this key once, a preset number of zeros is generated.

3-2 is a definition key operated to set the number of zeros generated when input key 3-4 is operated, and 2 is the number of zeros generated when zero input key 3-4 is operated. This is a zero indicator that displays .

FIG. 2 is a block diagram of the keyboard device shown in FIG. 1, and 3 indicates the key switches 3-1 to 3-4 in FIG. As a result, the key data generating section 4 generates a key code corresponding to the operated key. Reference numeral 6 denotes a random access memory (RAM), and a counter area 6-1 provided in a part thereof stores numbers from O to 9 that define the number of O's to be generated. A key code storage section 7 stores key data generated by operating the key switch 3. Control unit 5
are the RAM 6 and the key data generating section 4. This is a control section that performs control as shown in FIG. 4 using the key code storage section 7 and the key code storage section 7. Reference numeral 8 denotes a display section that stores display data for the display 2 that displays the number of zeros generated by operating the zero input key 3-4.

FIG. 3 shows the control section 5 of FIG. 2 in more detail, and this control section 5 consists of a microprocessor 5-1 and a read-only memory (ROM) 5-2.
The microprocessor 5-1 is controlled based on the program shown in FIG. 4 stored in the microprocessor 5-1, and other components are controlled using the data bus DB and address bus AB.

In addition, in the figures, elements given the same numbers as in other figures indicate the same elements in each figure.

Next, the operation of the keyboard device according to the present invention will be explained using FIG.

When the power is turned on, the RAM 6 is cleared in step 31 and the process proceeds to step S2, where the content "°0'° of the counter area 6-1 of the RAM 6 is transferred to the display unit 8, and the display 2 displays θ'. Step S3 waits for key power from key 3, and when key power is applied, step S4
Then, it is determined whether the key human power is zero definition key human power. When it is determined that the key is a zero definition key, the process advances to step S5 and waits for the next key force, and if there is a key force, it is determined in step S6 whether or not the key force is a zero definition key. If it is determined that it is not a zero definition key, step S7
Proceed to , determine whether it is a numeric keypad, and if it is determined to be a numeric keypad, the one digit number from 1 to 9 entered by the numeric keypad is 5
After the data is written in the counter area 6-1 of the RAM 6 in step S9 and the data in the counter area 6-1 is stored in the display section 8 in step S9, the process returns to step S5. If it is determined in step S4 that the key is not a zero definition key, the process proceeds to step SLO, where it is checked whether or not it is a zero input key.If it is a zero input key, the key is stored in the counter area 6-1 in the RAM 6 in step 311. The number of keys is stored in the key code storage section 7, and the process returns to step S3. If it is determined that the key is not a zero-input key, the process proceeds to step 312, where the key data generation section 4 converts the code into a code corresponding to the input key, writes it in the key code storage section 7, and returns to step S3.

Next, the actual operation will be explained using the drawings.

First, by turning on the power switch, step Sl
The counter area 6-1 in the RAM 6 is cleared, the 0 in the counter area 6-1 is stored in the display 8 in step S2, and O''° is displayed on the display 2, and the key 3 is operated in step S3. If the zero definition key 3-2 is operated here, the process advances to step S5 via step S4, and waits for the next key operation.0 If the numeric keypad (for example, "2P") is operated next. , step S6,
After proceeding to step S8 via S7 and writing the input data "2" to the counter area 6-1 of the RAM 6, proceeding further to step S9 and storing the data in the counter area 6-1 in the display section 8. According to indicator 2, °゛2°
" is displayed, and the process advances to step S5 to wait for the next key input. 6. Next, when the operator operates the zero definition key 3-2,
Proceed to step S3 via step S5.36 and wait for the next key power. When the operator inputs 2° to input the numerical value 200°, step S4, SIO
After proceeding to step 312 and writing the code signal corresponding to the input numerical value "2" into the key code storage section 7, the process returns to step s3 and waits for the next key input. When you operate step 34. In step Sll, which proceeds to step 311 via SIO, O's are generated as many as the number stored in the counter area 6-1 in the RAM 6. In this case, it is 2゛°, so °゛0
By generating 0'' and writing it into the key code storage section 7, 200'' is written into the key code storage section 7.

In addition, in the embodiment described in L, a case where multiple zeros are set is shown, but it is also possible to set other data other than zero, and furthermore, without providing a separate numeric keypad 3-3. Of course, keys in the JIS keys 3-1 may also be used.

[Effects] As described above, according to the present invention, the user can generate a plurality of pieces of the same data by key operation as necessary, so the operability is greatly improved.
