When the number of the lighted bar display elements 10 exceeds 10 pieces and the 11th bar display element 10-11 is turned ON. the 10th bar display element 10-10 is turned OFF. Thereafter. when the number of the lighted bar display elements is increased and the 11th bar display element 10-21 from the bar display element 10-10 is turned ON, the bar display element 10-20 is likewise turned OFF. Thus, the every 10th bar display element becomes the marking display.

Description

Detailed Description of the Invention The present invention provides analog display of integrated values and other values by sequentially lighting up a plurality of adjacent bar display elements in a fixed direction. This invention relates to improvements to bar display devices, and in particular, to simpler and easier-to-understand division displays that serve as the scales of the bar display elements. , a plurality of square display elements as shown in Figs. 1 and 2 are used in a display device in which the values to be displayed change very quickly and the user only needs to be able to visually read the relatively rough values. A display device is used in which display elements arranged adjacent to each other are sequentially turned on to display values in an analog manner.

However, such a square display device must display scale divisions in order to let the user know the displayed value to a certain extent. For this reason, conventionally, as shown in FIG.
b, 2c, 2d, etc. are made larger than other bar display elements to form a scale, or number display elements 4a for scale are placed above the bar display elements at regular intervals as shown in FIG.
4b', 4c.

4d=='5 was set up. However, such a method is not ideal because the segment shape becomes complicated and difficult to manufacture, and the display area must be correspondingly large.

Furthermore, conventional methods have been used in which scale numerical elements are printed on the cover glass that covers the display surface, thereby eliminating the need for separate display element shapes and numerical elements. It was difficult to align the display element and the printed scale, and there was a risk of position IW misalignment.

The present invention has been developed in view of the above-mentioned conventional problems.The purpose of the present invention is to change the shape of the display element for the division display for the scale in a bar display device that displays display values in an analog manner, and to create a new display. This can be done easily without the need to provide any elements.

In order to achieve the above object, the present invention determines a certain number of bar display elements for separation, and turns off only those bar display elements in which both bar surface thread elements adjacent on both sides are lit. It is characterized by being displayed in sections.

The present invention will be described in detail below based on the drawings.

FIGS. 3(a) and 3(b) are display mode diagrams showing display modes of a bar display device according to an embodiment of the present invention. In this embodiment, the entire feature of the delimited display is that the bar display is set every 10 lines.

First, as shown in FIG. 3(a), a bar display device is made up of a plurality of bar display elements arranged in a column, and as the display value becomes larger, the bar display element 10 arranged at the left end -1 to the right, elements 10-2, 10-3. '
10-4. ...and it lights up.

However, as shown in FIG. 3(b), when the number of lit bar display elements exceeds 10 and the 11th bar display element 10-11 lights up, the 10 bar display elements 10
-10 goes out. After this, the number of lit bar display elements increases, and the bar elements 10-20 go out.

In this way, when the number of bar display elements that are sequentially illuminated increases, every 10th bar display element among the bar display elements that are illuminated is turned off, and the display value becomes a divided display of "1o".

FIG. 4 is a circuit diagram of the bar display device according to FIG. 3.

Bar display element 10-1. 10-2. ...1O-10
-=10-(H-1), 10-n are each driver 1
2, the display element extinguishing circuit 14-1, 14-2.・
14-10. ...14-(n-1).

14-n. This display element extinguishing circuit is a circuit that extinguishes the connected bar display element when the bar display elements adjacent on both sides of the connected bar display element are both turned on. -1～
14-(n-1) has the same circuit configuration, and is a flip-flop (hereinafter referred to as FF) 16. And gate 18. Consists of or gate 2°. In addition, the display element extinguishing circuit 14-n
It consists of only 1dFF22.

The set inputs S of the FF group 16 and FF 22 constituting the display element light-off circuit group 14 are inputted with outputs Q, -Qn of the shift register 24 that generates display signals. This shift register 24 counts the constant periodic signal φ1 from the reference signal generator 26, and has an FF 28 at its D input.
The Q output of is input. A constant period signal φ from the reference signal generator 26 is input to the clock input of this FF 28, and the L input is input to the D input.
signal is input. Similarly to the reset input R of the shift register 24, the output of the detection signal generation circuit 30 is input to the set input S thereof. Detection signal generation circuit 3
0 outputs a pulse that sets the period during which the shift register 24 continuously counts. Therefore, if the interval between the generated pulsed pulses is short, the count value of the shift register 24 will be small, and if the interval is long, the count value of the shift register 24 will be small. The count value of the shift register 24 becomes sharper. The output of this detection signal generation circuit 30 is also input to the reset input R of the FF group 16 and FF 22 via the ORG1 group 20.

On the other hand, the outputs Q1 to Qn of the shift register 24 are 0FF1 in the corresponding display element turn-off circuits 14-1 to 14-n.
．． 6-1 to 16-(n-1), input to the set input S of 22, and exit. If the outputs Q2 to Qn are switched, the AND gate group 18- of the display element light-off circuits 14-1 to 14-(n-1)
1 to 18-(n-1) are inputted one by one, respectively. This AND gate group 18-1 to 18-(n-1
), the Q output of FF32 is input to all other inputs. The constant periodic signal φ2 of the reference signal generator 526 is input to the clock input φ of the FF 32, and the input and reset input R is the output from the delimiter display setting circuit 34 that sets the bar display element for delimiter display. A signal is being input.

Separator display setting circuit 34b, external switches 36a, 3
6b, 36c and 36d, counter 38° exclusive noate 40, 42, 44° 46, and further Nante gate 48. Consists of AND gate 50°52. FF
The outputs of exclusive NOR gates 40°42.44 and 46 via an AND gate 52 are input to the D input of 32. The switch 36a and the output Q7n of the counter 38 are input to the exclusive NOR gate 40, and the external switch 3 is input to the exclusive NOR gate 42.
6b and the output Q15 of the counter 38 are input. And the exclusive Noah gate 44 has an external switch 3.
6c and the outputs Q and +o of the counter 38 are input to the AND gate 46, and the switch 36d and the output Q5 of the counter 38 are input to the AND gate 46. The constant periodic signal φ from the reference signal generator 26 is input to the clock input φ of the counter 38, and the output of the AND gate 52 is input to the reset input R. Also, the output Q5 + QI of the counter 38
OI Q, +51 Q21+ is input to the Nant gate 50, and the output of the Nant gate 50 is input to the AND gate 48 together with the constant period signal φ1. The output of this AND gate 48 is input to the reset input R of the FF 32.

The operation of this circuit will be explained below using the time chart of FIG.

When only 36b and 36d of the external switch group 36 are closed, the shift register 24 is temporarily reset by a pulse signal from the detection signal generation circuit 30, and at the same time, the FF
28 is set and the Q output becomes H. In response to this Q output signal, the shift register 24 only outputs Q1 and becomes H.
Thereafter, in synchronization with the constant periodic signal φ1 from the reference signal generator 26, the H signal transitions from output Q+-+Q2→Q3→. Also, the Q output of FF28 is the first constant period signal φ
, 'Niri' changes from H to L. Then, the output Q of the shift register 24, II Q21 Q3+ ・ sequentially becomes H, and at the same time the FF 16-1.16-2.16-3
．． The Q outputs of the bar display elements 10-1 and 10-1 also become H in sequence. 10-2. 10-3.・ is turned on after ItF as shown in FIG. 3(a).

At the same time that the shift register 24 starts counting the constant period signal φ1 and an H signal is transferred from the output Q to the output Q2, the counter 38 in the delimiter display setting circuit 34 also starts counting the constant period signal φ1. And counter 38
The outputs Qa, Qb, Q, c, Qd are rloloj(10
10), that is, the output Q of the shift register 24. When the signal of ■1 moves from to the output Qu,
The outputs of exclusive NOR gates 40 to 46 all become H, and accordingly, the output of AND gate 52 also becomes ■
(Then, after this, when the constant period signal φ2 input to the clock input φ of FF32 falls, the FF32
The Q output of becomes H. Further, the counter 38 is reset by the H output of the AND gate 52. As a result, the outputs Qa+ Qbl QCI Qa+ are all low, the output of the Nant gate 48 is high, and the AND gate 50 is fully opened. Therefore, after this, when the constant periodic signal φ1 becomes ■(, the FF32 is reset and the output Q changes from H to L.The pulse from this FF32 is in the open state because the output Qn is in the state of ■) at this time. F' through an AND gate 18-10 and an OR gate 20-10
Let F16-10 be the temporary set L and Q output tL. Even in this state, the H signal is sequentially transferred to the Q output of the shift register 24 until the detection signal generating circuit 30 also generates a pulse signal and the shift register 24 and the FF group 16 are reset. Therefore, as a result, bar display elements 10-11. 10-12. . . , only the bar display element 10-10 goes out.

Thereafter, when the bar display elements 10 to 21 light up, the value of the counter 38 becomes rloloJ again9, and the output of the AND gate 52 becomes H. As a result, a pulse signal is output from the Q output of the FF 32 again.

At this time, only the AND gate 18-20 is open, and the AND gate 18-20. A pulse signal is input to the input R of the FF 16-20 via the OR gate 2°-20i. As a result, the Q output of the FF 16-20 becomes L, and the bar display element 10-20 turns off. This is further 1
The same thing is done for every O bar display elements 10-30.

According to this embodiment, as the bar display elements are sequentially lit, every 10 bar display elements 10-10-1
(O is a natural number) is turned off when the bar display elements adjacent on both sides are lit, and can be recognized more accurately and easily as a division display of every 10 lines. In addition, there is no need to use special segment shapes as in the past, and there is no need for a new display element for displaying scales, making it easy to manufacture and requiring less display area. Furthermore, in this example,
By using the external switch group 36, the segment shape can be freely changed from the segment shape part that is displayed as the 9th section. For example, Sui/Chi36
If you close a, 36c'i and open the other switches, every fifth segment will turn off. Since the delimiter display can be changed freely in this way, versatility is widened.

In this embodiment, a display device including bar display elements arranged in columns has been described, but the present invention may also be implemented in a display device in which bar display elements are arranged circumferentially.

As described above, according to the present invention, in a bar display device consisting of a plurality of bar display elements, all of the bar display elements for separation are determined for every certain number of bar display elements, and among these bar display elements,
By extinguishing only the bar display elements that are lit up on the bar display elements adjacent to both sides, it is possible to clearly divide the display, and the user can more easily know the magnitude of the displayed value.

Furthermore, there is no need to make the bar display element a special shape for displaying scales or to provide a special scale display, which facilitates manufacturing and eliminates the need to increase the display area.
