よう(こなっている。The eddy current plate type timer has permanent magnets arranged on both sides of an eddy current plate made of copper or aluminum, and either the eddy current plate or the permanent magnet is a rotating body, and the rotation of this rotating body generates eddy currents in the eddy current plate. This occurs so that a braking force is applied to the rotation of the rotating body.

以下、本発明の一実施例を第1図Oこより説明する。平

A vortex disk mounting shaft portion 3b is formed to protrude from the magnet mounting shaft portion 3a toward the base plate 2 side. The inner diameter portion of the magnetic induction plate 5 to which the permanent magnet 4 is fixed is fixed to the magnet mounting shaft portion 3al. A non-magnetic pipe shaft 7 to which an eddy current disk 6 is fixed is rotatably inserted into the eddy current disk mounting shaft portion 3b.
The pipe shaft 7 is vertically positioned by a collar 81 fixed to the tip of the vortex disk mounting shaft portion 3b. A gear portion is provided on the outer periphery of the vortex disk 6I, and a gear 9 rotated by a drive source (not shown) meshes with this gear portion. A magnetic induction plate 11 to which a permanent magnet 10 disposed opposite to the permanent magnet 4 is fixed is rotatably inserted into the other base plate 2, and a speed nut or the like is attached to a portion protruding outward from the base plate 2. A fixing spring 12 is engaged to fix the base plate 21. Also, the ground plate 2 of the magnetic induction plate 11
Outer end of (This is the groove 1 for engaging a screwdriver etc.)
1a is formed. In addition, the two permanent magnets 4.1
For example, in Figure 2, ζ
As shown, the opposing surfaces are multipole magnetized.

一定の回転数で回転する。Now, the opposing magnetic poles of the permanent magnets 4.10 arranged opposite to each other are arranged so that the opposite poles N and S face each other as shown in FIG.
A drive source (not shown) is started to rotate the gear 9. This causes the vortex disk 6 to rotate and therefore the vortex disk 6
Due to the magnetic flux of the permanent magnets 4.10, eddy currents are generated and a braking force is applied to the eddy current disk 6, so that the eddy current disk 6 is controlled and rotates at a constant rotational speed.

る。Next, the $11a# driver of the magnetic guide plate 11 is engaged to rotate the magnetic guide plate 11. This causes the permanent magnet 10 to also rotate. Then, the opposing poles of the two permanent magnets 4.10 are the same, that is, N and N, and S and 8. Even when the eddy current disk 6 rotates, almost no eddy current is generated in the eddy current disk 6, and the eddy current disk 6 rotates at high speed without being braked.

By making the opposing magnetic poles the same polarity, the braking can be adjusted to the minimum level, so that the desired rotational speed can be adjusted freely within the braking range by arranging the opposing permanent magnets 4.10. Permanent magnets 4.10 on both sides of the rounded vortex disk 6
Since it has a very simple structure in which one permanent magnet is configured to be rotatably adjustable, it can be made inexpensive and thin.

い咎の効果を有する。As is clear from the above description, according to the present invention, a rotatable vortex disk is provided, and four permanent magnets are arranged concentrically with the vortex disk, facing each other on both sides of the vortex disk. Since at least one of the permanent magnets is rotatably adjusted concentrically with the eddy current disk, the speed can be easily adjusted to a desired rotational speed.Also, the structure is extremely simplified, It can be made inexpensive and thin.Since it is a completely magnetic circuit, there is no leakage flux, and it has the advantage that there is no effect even if a magnetic body is brought close to it from the outside.
