Press and insert the digital setting device A' into the provided mounting hole, sandwich the panel between the flange 1b' of the case body 1' and the elastic pieces 6a, 6a of the mounting plates 61, 62, and attach the digital setting device A' to the panel. A predetermined number was set by rotating the rotating piece 2b' using a method such as the above.

(c) Problems to be solved by this invention In the digital setting device A' as described above, two mounting plates 61,
62 and two digital setting device units B are required, resulting in a problem in that the manufacturing cost is high.Furthermore, after the two digital setting device units are assembled and fixed together, the mounting plate 61, 62
The problem is that the number of assembly steps increases.

(d) Means for solving the problem This invention was proposed to solve the above problem, and aims to reduce costs and simplify assembly. A flange portion is formed, a window hole and a plurality of holes attached to the window hole are formed, opening recesses are formed on the back side, and elastic pieces for panel attachment are formed on the outer walls of the opposing side walls of the base, respectively. A plurality of symbols are marked on the peripheral wall of the base that can be seen through the window hole, and a plurality of rotating pieces for rotation that are partially exposed through the hole are provided on one side of the peripheral wall in correspondence with the symbols. A recess is formed in both side walls of the base, a through hole is formed in the center of the bottom of both the recesses, and a gear portion having a plurality of teeth is formed at the peripheral edge on both sides of the through hole. A partition wall is formed on a base provided in an opening recess of the case body, and a shaft for pivotally supporting the rotating wheel on both side walls of the partition wall contacts a gear portion of the rotating wheel to prevent malfunction. This is achieved by forming a digital setting device for the panel from a bottom plate on which a prevention piece is formed.

(e) Function The digital setting device A of this invention is composed of a case body 1, a rotary wheel 2, and a bottom body 3, and since the case body 1 is formed with elastic pieces 1f and 1f for panel attachment, it is easy to use for panels. The mounting plates 61 and 62 are no longer necessary, and since two rotary wheels 2 are disposed on the partition wall of the bottom plate 3, two digits can be formed at once.

(f) Example Hereinafter, this invention will be explained based on an example shown in FIGS. 1 to 3.

Reference numeral 1 denotes a case body, in which a flange portion 1b is formed along the peripheral edge on the front side of the base 1a, and two window holes 1c are formed in the center along with a hole 1d.

A shaft hole 1h and a square hole 1i, 1 are provided on both side walls of the base 1a.
i are formed respectively, and elastic pieces 1f and 1f for panel attachment are formed on the upper and lower sides of the side walls, respectively, and these elastic pieces 1f and 1f sandwich the panel 4 with the flange part 1b to attach the case body 1 to the panel. 4
It serves the purpose of attaching it to the

An open recess 1e is formed on the rear side of the base 1a, and guide grooves 1g, 1g are formed in the center of the upper and lower walls of the inner peripheral wall of the open recess 1e.

2 is a rotary wheel, and the base 2a has 10 numbers from 0 to 9 marked at regular intervals on the peripheral wall, and on one side of the peripheral wall there is a rotary wheel for rotating the rotary wheel 2. Ten rotating pieces 2b are formed at regular intervals corresponding to the numbers, and
Recesses 2c, 2c are provided in both side walls, and a through hole 2d is provided in the center at the bottom of the recesses 2c, 2c provided in both side walls, and peripheral edges on both sides of the through hole 2d are provided. A gear portion 2e having 10 teeth is formed in correspondence with the numbers.

Reference numeral 3 denotes a bottom body, and a partition wall 3b located in the opening recess 1e of the case body 1 is formed in the center of the base 3a, and shafts 3c, 3c are formed in the same position on both side walls of the partition wall 3b. The prevention pieces 3d, 3d are formed diagonally with the protruding pieces 3e, 3e in opposite directions, and the preventing pieces 3d, 3d are formed on the gear parts 2e, 2e of the rotary wheels 2, 2. 3e
This serves to prevent the rotating wheels 2, 2 from malfunctioning by bringing them into contact with each other.

Furthermore, protrusions 3f, 3f are provided on both side walls of the base 3a, respectively.

Next, to explain the assembly, first, the rotary wheel 2 is inserted into the through holes 2 on both side walls of the partition wall 3b of the bottom body 3.
The shafts 3c, 3c are inserted into the shafts 3c, 3c, and the protruding pieces 3e, 3e of the prevention pieces 3d, 3d are inserted into the gear portion 2.
e and 2e are placed in contact with each other.

At this time, the rotating wheels 2, 2 are the rotating pieces 2b,
2b are arranged so that they are lined up in the same direction.

And a bottom body 3 on which rotating wheels 2, 2 are arranged
is inserted with the free end of the partition wall 3b corresponding to the guide grooves 1g, 1g of the opening recess 1e of the case body 1.

When the bottom body 3 is inserted into the opening recess 1e of the case body 1, the free ends of the shafts 3c, 3c of the bottom body 3 fit into the shaft holes 1h, 1h of the case body 1, respectively, and the protrusions 3f, 3f are fitted and locked into the square holes 1i, 1i, respectively, and the bottom body 3 is attached to the case body 1.
It is provided so that it does not come out from the opening recess 1e.

At this time, the rotating wheels 2, 2 are provided so that the numbers can be seen through the window holes 1c, 1c of the case body 1, and the rotating pieces 2b, 2b are partially exposed through the holes 1d, 1d.

If the bottom body 3 is provided in the opening recess 1e of the case body 1, the digital setting device A is formed, and the digital setting device A is inserted into the predetermined mounting hole 4a provided in the panel 4. Insert the panel 4 by pressing it from the front side, and attach the panel 4 to the flange part 1b and the elastic piece 1.
Attach the digital setting device A to the panel 4 by sandwiching it between the dials f and 1f, and rotate the rotary piece 2b of the rotary wheel 2 with your fingers or the like to set a predetermined number.
