[Detailed Description of the Invention] The present invention relates to a data input display device, and more specifically, the present invention has a function of reliably identifying display elements waiting for data input.

Conventionally, as shown in FIG. 1, this type of data input display device includes a numeric keypad 1 for data input and LEDs 2a ₁ , 2a ₂ , 2a ₃ , 2 for decimal point display.
7 segment 4 digit time display with a ₄
LED (hereinafter abbreviated as LED with decimal point) 2b ₁ , 2
A display 2 consisting of b ₂ , 2b ₃ and 2b ₄ , a driver 3 that drives this display 2, control of this driver 3, management of the numeric keypad 1 for data input, and other controls via a control line 4. A device is known that is composed of a control device 5 that controls a controlled device. In addition, the first
In the figure, 6 is a decimal point drive line that connects the decimal point display LED 2a and the control device 5.

According to the above device, for example, the time data “φ1 hour
When inputting "23 minutes" using the data input numeric keypad 1, first, as shown in Figure 2a, the decimal point display LED _{2a 1} of the 1st digit LED 2b ₁ lights up and the LED 2b ₁ is waiting for data input. When data “φ” is input, LED2b ₁ displays “φ” as shown in Figure b, and LED2a ₁
disappears, and the decimal point display LED 2a ₂ of the second decimal point LED 2b ₂ lights up to indicate that the LED 2b ₂ is waiting for data input. Thereafter, when data "1", "2", "3" are input, c, d,
As shown in e, the LEDs 2b ₂ , 2b 3 , 2b ₄ with decimal points in the 2nd, _3rd , and 4th digits display these data sequentially, and the decimal points in the 2nd, 3rd, and 4th digits The display LEDs 2a ₂ , 2a ₃ , and 2a ₄ light up in sequence.

In other words, the decimal point display LEDs 2a ₁ , 2a ₂ , 2
A ₃ and 2a ₄ are lit, allowing you to determine which digit is waiting for data input. However, it requires LEDs _{2a 1} to 2a ₄ for decimal point display for each digit, which increases the cost, and even if these decimal point display LEDs _{2a 1} to 2a ₄ light up, there are problems such as difficulty in determining which digit is waiting for data input. It was hot.

This invention was developed in view of the above circumstances, and its purpose is to display the digit position of the next data to be input and the type of data that can be input at that digit position every time data is input. To provide a data input/display device capable of simultaneously providing guidance on elements and sequentially and correctly inputting target data into input-waiting digit positions without error and without increasing costs.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 3 is a block diagram of the data input display device of the present invention, and FIG. 4 is a specific circuit diagram of the same block diagram. Reference numeral 7 in the figure denotes a key device for data input, which is composed of a key matrix such as a numeric keypad or an input mode start key.

In addition, 8 is a display unit, which is a 7-segment time display LED that does not have a decimal point display LED.
Four display elements 9, 10, formed by a
11 and 12 are equipped. Time data “00 hours”
00 minutes (24:00)” to “23:59”.
The display element 9 displays the first digit number, the display element 10 displays the second digit number, and the display element 11 displays the third digit number,
The display element 12 also displays the fourth digit number.

Reference numeral 14 denotes a driver for driving the display 8, which includes seven segment driver transistors Tr ₁ provided corresponding to the seven segment time display LED 8a, and each display element 9, 10, 1.
It consists of four grid driver transistors Tr ₂ provided corresponding to transistors Tr 1 and Tr 12, and a decoder 15 that supplies signals to the bases of these transistors Tr ₁ and Tr ₂ .

Reference numeral 16 denotes a control device consisting of a microcomputer, which controls the driver 14, manages the data input key device 7, and outputs input data to the outside or controls a controlled device (not shown) using the input data. control. The control contents of the driver 14 are as follows: display elements 9, 10, 11,
12 is to operate the driver 14 so as to periodically display (cycle lighting) the numbers that can be input. In detail, when inputting data (at the start of operation), the first digit display element 9 lights up the inputtable data “φ, 1, 2” in cycles (φ → 1 → 2 → φ)
The driver 14 is controlled to do so. Next, when the display element 9 displays, for example, input data "φ", the second digit display element 10 lights up the input data "φ, 1...8, 9" in cycles (φ→
1...9→φ).
After this, when the display element 10 displays, for example, input data "1", the third digit display element 1
The driver 1 lights up the data "φ, 1...4, 5" that can be inputted in cycles (φ→1...5→φ).
Control 4. After that, when the display element 11 displays input data "2", for example, the fourth digit display element 12 displays inputtable data "φ, 1...
The driver 14 is controlled so as to light up the input data "8, 9" in cycles (φ→1...9→φ).The data input mode in which the fourth digit display element 12 displays, for example, input data "3" is completed; The cycle light stops.

FIG. 5 shows an input routine flowchart for the first digit display element 9, and the control device 16 controls the driver 14 in accordance with this flowchart. That is, when the input routine of the first digit display element 9 starts, the display element 9 displays "φ", and then the data input key device 7
It is determined whether or not there is a key input. When there is no key input, the data “φ×
1000", "1" is added. This results in "φ+1", which is smaller than "2", so the decoder 15 sends the transistor Tr ₂ provided corresponding to the display element 9. A signal is sent to the base of a predetermined transistor _Tr1 , and the display element 9 displays "1".Then, it is determined again whether or not there is a key input, and if there is no key input, the data "(φ+1)" is sent to the decoder 15. ×1000”
After sending, "1" is added. This allows “φ
+2", which is equal to "2", so the display element 9 similarly displays "2", and it is determined whether or not there is a key input again. If there is no key input, the data is sent to the decoder 15. “(φ+2)
×1000", "1" is added, but since this value is larger than 2, display element 9 displays "0". In other words, while there is no key input, display element 9 displays "0". → These numbers are displayed repeatedly in the order of 1 → 2 → 0. When there is a key input, it is determined whether the input data is "3" or more,
When the input data is "φ", the input is confirmed and the input data is stored in the first digit memory (not shown). As a result, the display element 9 does not cycle and displays the data "φ". and,
The input routine for the second digit display element 10 starts. When the input data is "3" or more, it is not displayed on the display element 9.

Note that 17 in FIG. 3 is a control line that connects the control device 16 with another controlled device (not shown).

Next, the operation of the above device will be explained.

For example, when inputting the time 1:23, that is, φ123, into the data input key device 7, first, as shown in FIG.
As shown in the figure, the first digit display element 9 displays inputtable data "φ, 1, 2" in cycles to indicate that it is waiting for input. When data "φ" is input using the data input key device 7, this is displayed on the display element 9, and the second digit display element 10 lights up cycle of inputtable data "φ, 1,...9" and waits for input. It represents something (see b in the same figure). When data "1" is input, it is displayed on the display element 10, and the third digit display element 11 lights up cycle of inputtable data "φ, 1...5" to indicate that it is waiting for input (c
reference). When data “2” is input, it is displayed on display element 11, and the fourth digit is displayed on display element 12.
The inputtable data "φ, 1 . . . 9" is displayed in cycles to indicate that it is waiting for input (see d in the same figure). When data "3" is input, it is displayed on the display element 12, thereby ending the input mode and stopping the cycle lighting.

In the above embodiment, a display using a 7-segment time display LED 8a is shown, but other displays such as an FL display may be used, and the number of digits may also be 4.
Not limited to digits.

Further, in addition to time data, data such as year, month, and day may also be input.

Furthermore, the display is not limited to numbers, and characters such as alphanumeric characters may be displayed.

As explained above, according to the present invention, the display element waiting for input itself periodically displays symbols such as numbers that can be entered (cycle lighting), so that the display element waiting for input is reliably displayed. In addition to being easy to distinguish, there is no need for an LED for displaying the decimal point, which does not increase costs. In addition, symbols such as numbers that can be entered at that digit position are periodically displayed on the display element of the digit position that is waiting for input, and the digit position of the data to be input at that time and the type of data to be input are indicated. Since the guidance is displayed on the display elements at the same time,
Even an inexperienced user can accurately input target data at a target position, there is no risk of inputting incorrect data, and the operability of key input can be improved.

Furthermore, as long as the data entered from the data input key device is one of the symbols that can be entered in the display digit at that time, the input data is immediately taken in and displayed as valid data, which speeds up the input operation. is not affected by the display cycle of symbols such as numbers, and the input operation speed will not be slowed down.

Therefore, the data input display device of the present invention has the following features:
Function keys for audio equipment, etc.
For example, it can be used to great effect as a numeric keypad for timer selection, station memory keys for FM tuners, channel keys, day of the week keys for setting timers, etc.
