Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a display device that displays the amount of light, gas, liquid, viscous material, granular material, etc. that passes within a unit time.

(Prior art) Conventionally, in order to control the physical quantity that passes within a unit time, a plurality of passage holes are provided in a disk that prevents the physical quantity from passing through, corresponding to the physical quantities to be controlled, and the circular plate is is rotated and the corresponding passage hole is inserted into the flow path to control the physical quantity passing through.

In such a device, in order to display the size of the passage hole corresponding to the physical quantity inserted into the flow path, a long hole 2 is opened in the display board 1 as shown in FIG. Multiple displays 2.8 near the long side 2b of
4, . . . 16, and one index 3a was provided on the outer periphery of the disk 3, and the indication indicated by the index 3a was visually recognized as the size of the passage hole. Also, Figure 3a,
As shown in b, an indicator 4 is provided on one of the long sides of the elongated hole 2, and markings 2.8, 4,...16 are placed on the outer periphery of the disc 3.
was installed, and the display indicated by indicator 4 was visually recognized as the size of the passage hole.

(Problem to be solved by the invention) However, in the former case, the necessary rotation angle is regulated by the area of the passage hole, so if the orthogonal diameter of the disk is small, a large rotation angle is required, and as shown in Figure 3 a. This has the disadvantage that the hole cannot fit inside the hole, and the necessary area for the passage hole cannot be obtained unless the diameter is increased in order to fit the hole. Furthermore, the latter has the disadvantage that the numbers are provided on the outer periphery of the circle, which makes the disk thicker, and furthermore, when manufacturing the disk, it becomes difficult to construct a cutting die.

The present invention has been made in view of the above-mentioned circumstances, and aims to provide a compact display device with a simple configuration.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a plurality of indicators on the outer peripheral surface of a rotatable disk that regulates the physical quantity passing through the disk. The outer peripheral surface of the disk protrudes from the elongated hole and rotates to make the indicator visible, and a display corresponding to a physical quantity is provided along the longitudinal direction of the elongated hole, and the indicator points to the display. The disc is configured to hold the disc in position.

With this configuration, the object of the invention is fully achieved.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, and FIG. 2 shows the display section of FIG. 1 viewed from the left side.

In FIG. 1, the disk 3 that prevents the passage of physical quantities has passage holes 5a...5 that allow the passage of physical quantities.
f is opened so that the diameter gradually becomes smaller in the counterclockwise direction at 60 degree pitches with 5a as the maximum diameter. Click holes 6a...6f are opened at a pitch of 60 degrees from the passage hole to the outer periphery thereof, corresponding to the passage hole.

Marker 7a is located at a position α degree counterclockwise from the line connecting the passage hole 5d and the center of the disk 3, leaving a step on the back surface of the disk 3 on the outer periphery of the disk 3 as a slit-shaped recess extending to the surface. is formed. Markers 7b and 7c are formed counterclockwise from the mark 7a at a pitch of 2α degrees.

A mark 8a is formed on the outer periphery of the disc 3 at 180 degrees from the mark 7a as a slit-like recessed part leaving a step on the front surface of the disc 3 and extending to the back surface. Markers 8b and 8c are formed counterclockwise from the mark 8a at a pitch of 2α degrees.

The disc 3 is rotatably supported by a shaft 10 installed in the box 9, and is click-stopped by a spring 11 fixed to the box 9 and click holes 6a to 6f.

A part of the outer periphery of the disc 3 protrudes outward from the elongated hole 2 of the display board 1 glued to the side wall 9a of the box body 9, and indicators 7, 7a, 7b, 7c and 8 provided on the outer periphery
8a, 8b, and 8c are configured so that they can be visually recognized as shown in FIG. 2a and b.

As shown in Fig. 2, the indicators 7 and 8 indicate 2.8, 4, 5.6 on the right side of the elongated hole 2 and 8, 11, 11 on the left side of the elongated hole 2 along the longitudinal direction of the elongated hole 2. It is marked 16.

Along the longitudinal direction of the elongated hole 2, 2.8 is displayed at the position corresponding to the index 7a in FIG. ing. Indications on the left side of the elongated hole 2 are provided at positions corresponding to the indicators 8a, 8b, and 8c on the disc 3.

Next, the operation shown in FIG. 1 will be explained.

Now if α degree is 20 degrees, disk 3 will move clockwise.
When rotated by 60 degrees, the indicator 7a enters the elongated hole 2 and becomes invisible, but the indicator 7b appears and shows the display 4 in FIG. 2b. Further, when rotated by 60 degrees, the index 7c shows a reading of 5.6.

Now rotate another 60 degrees clockwise to index 7c.
enters the elongated hole 2, but the index 8a appears and the second
8 is shown on the left side of the elongated hole 2 in the figure.

In this way, it is possible to display twice as many numbers within a certain visible interval, and while providing an index in the means of directly controlling the physical quantity, displays can be made at intervals shorter than the control movement amount. It can be carried out.

(Effects of the present invention) In the present invention, a plurality of indicators are provided on a disk that directly controls physical quantities, and display means are provided along both long sides of a long hole from which the outer periphery of the disk protrudes. The number of change steps can be displayed at short intervals, and a compact display device can be obtained, which has been used prominently to display the aperture of a camera, the display of a flow meter, etc.

Note that the present invention can be modified and implemented as appropriate within the scope of its gist.

For example, the display provided on both sides of the elongated hole can be shifted to the left or right, or the left and right colors can be changed, and the indicators 7 and 8 on the outer circumference of the disk can be made to match the color of the display to improve visual recognition. It becomes easier. The display may be a suitable mark or figure.
