Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a scale display plate of a setting device for setting a physical quantity such as time, temperature, and number.

<Prior Art> There is known a timer of a timed-switching type that allows a user to select a timer setting time period, for example, 30 seconds, 1 minute, 10 minutes, 30 minutes, 1 hour, 6 hours, etc. There is.

As the structure of the display board of the timer of this type, there are prepared display boards of only the kinds of set time limits, and one of them is used.
It is known to select and replace a sheet. In such a structure, there is an inconvenience that a plurality of remaining unselected display boards must be stored.

<Problems to be solved by the invention> The problem to be solved by the invention is, for example, that the full scale is 30 seconds.
The question is whether it is possible to realize 8 series of graduations such as 1 minute, 3 minutes, 10 minutes, 30 minutes, 1 hour, 6 hours and 12 hours with only one display board. Moreover, it is possible to manufacture such a display board as thin and light as a normal one display board.

<Means for Solving the Problems> A scale display plate of the present invention has a circular hole at a symmetrical position with respect to a line of symmetry, and a scale and a transparent window which are different from each other are formed around the circular hole. Of the sheet is bent along the line of symmetry and both ends thereof are adhered to each other to form a two-fold fixed display plate, and between the fixed display plates, there are circular holes corresponding to the circular holes, A series of variable display contents, in which numerical values, characters, etc. are printed at a position corresponding to the above-mentioned transparent window, are sandwiched between a plurality of rotary display plates with a predetermined rotation angle on both front and back sides, and , The percentage of full scale displayed by the above numerical values is different for each series.

<Operation> When a series of numerical values of the rotary display plate is combined with the transparent window of the fixed display plate, one series of scale display plates is formed. When the rotary display plate is rotated by a predetermined angle, another series of scale display plates is formed. In this way, it is possible to selectively configure a plurality of series of scale display plates for the front and back surfaces independently.

<Embodiment> FIG. 1 shows an exploded front and back side view of an embodiment of the present invention.
FIG. 2 is a front and back side view of the assembled embodiment of the present invention.

The scale display plate of the present invention comprises a fixed display plate 1 and a rotating display plate 2. This fixed display plate 1 has a sheet 1a as shown in FIG. 1 (a), which is folded along a line of symmetry 3 except for the circular portion where the rotary display plate 2 is sandwiched, and the bent portion and both end portions are Are glued together. Rotation display plate 2 is front and back 2
The fixed display plate 1 is rotatably sandwiched between the fixed display plates 1, and the rotary display plate 2 is partially exposed in the left and right cutouts of the fixed display plate 1. The exposed portions 2a and 2b can be turned with a fingertip.

The shape of the sheet 1a of the fixed display plate has outer contours 4A and 4B and circular holes 5A and 5B which are symmetric with respect to the line of symmetry 3, and graduated marks 6A and 6B different from each other around the circular holes 5A and 5B. ,
A plurality of transparent windows 7A ... 7A, 7B ... 7B for displaying numerical values corresponding to the scale and transparent windows 8A, 8B for displaying units are formed. This sheet 1
By bending a along the line of symmetry 3 and adhering it,
A fixed display panel 1 having a circular hole 5 in the center and different scales and a transparent window on the front and back is obtained.

The rotary display plate 2 is a disk-shaped product having a circular hole 9 having substantially the same size as the circular hole 5 of the fixed display plate 1 in the center, and marks 10 ... Four series of numerical values and units are printed. The numerical values belonging to one series on the surface and the arrangement positions of the units 11A correspond to the transparent windows 7A ... 7A and 8A on the surface of the fixed display plate, and four series are printed at 90 ° intervals. Similarly, the numerical values belonging to one series on the rear surface and the arrangement positions of the units 11B correspond to the transparent windows 7B ... 7B and 8B on the rear surface of the fixed display plate, and are 90 °.
Four series are printed at intervals. When the rotary display plate 2 is sandwiched by the fixed display plates 1, the marks 10, 1
When 0 is aligned in the left-right direction, a series of numerical values and units appear in the front and back perspective windows as shown in FIG.

The scale display plate formed in this way is mounted by inserting the outer contour 4 of the fixed display plate 1 into a recess (not shown) provided in the peripheral portion of the front face of the case of the setting device. By fitting the mark 10 of the rotary display plate 2 to the protrusion (not shown) provided on the front peripheral portion of the case, the rotary display plate 2 is positioned and fixed. Then, when changing the setting time of the scale display plate to another type (for example, when changing the full scale from 10 minutes to 30 minutes), the scale display board is set from the front of the case of the setting device. After removing once, the exposed portion 2a of the rotary display plate 2,
2b is operated to rotate the rotary display plate 2 by a predetermined amount, thereby displaying fixed display contents indicating a desired set time limit on the transparent windows 7A and 8A of the fixed display plate 1, and then again performing the above-mentioned operation. It is positioned and fixed on the front of the case of the setting device. In that case, the transparent windows 7A, 8A on the back side of the fixed display board 1
If the fixed display content appearing in (1) has already been set to the desired setting time, it is sufficient to remove the scale display plate from the front of the case of the setter, turn it over, and then attach it again.

The configuration of the setting device using this display plate is such that a variable resistor adjusted by a knob fitted in a circular hole in the center of the display plate is provided, and a changeover switch is provided behind the display plate.
As illustrated in the drawing, the variable resistor 12 and the changeover switch 13 are connected to the integrated circuit 11.

<Effect of the Invention> According to the present invention, since all the graduations that can be selected can be realized with one graduation display plate, the manufacturer can reduce the number of types of products and the number of parts, and the mass productivity. Therefore, it is not necessary for the user to store the scale display plate unlike the conventional product.
