おいて大変有効である。[0009] Shakers are used for culturing, stirring, pulverizing, etc., but various containers are used by users. Therefore, even if the same sample solution is used, the movement of the sample solution in the large Erlenmeyer flask and the small test tube or microtube will be different even if the sample solution is operated at the same shaking speed and the same amplitude, and the result will be different. Therefore, it is very effective in the above-mentioned application to be able to change and adjust the amplitude in accordance with the change of the shaking speed.

目的を達成することができないこととなる。[0010] In general, in a culture application, when a large container is used, the amplitude of the sample is increased, and even if the shaking speed is relatively slow, the movement of the sample liquid becomes intense, and aeration is actively performed. Can be achieved. Conversely, in the case of a small container, sufficient aeration is not performed unless the amplitude is reduced and the shaking speed is increased, so that the same purpose as the large container cannot be achieved.

うにしたのである。The shaking speed can be reduced by increasing or decreasing the power supply to a motor for rotating the rotary shaft 1. In this embodiment, the dial 10b of the eccentric rotary shaft is held by hand. The amount of eccentricity of the eccentric rotating shaft with respect to the rotating shaft 1 can be adjusted to be large or small by an extremely simple operation so that the amplitude of the shaking table 15 to be fitted and inserted can be changed and adjusted to be large or small.

To stop the rotation shaft 1 from rotating. Then, the bevel gear shaft 10 is rotated forward so that the bevel gear surface 10a meshes with the bevel gear surface 9a of the bevel gear 9, and then the bevel gear shaft 10 is rotated. In this case, when the amount of eccentricity of the eccentric rotary shaft 7 is increased, the eccentric rotation shaft 7 rotates to the right as shown in FIG. 3A, and when it is decreased, it rotates to the left as shown in FIG. 3B. Then, the bevel gear 9 rotates around the non-rotating rotating shaft 1 and the gear 6b,
In conjunction with the transmission gear 6a and the vertical penetrating shaft 4, the horizontal revolving plate 5 revolves while shifting the meshing position with the ball plunger 8 to move the position of the eccentric rotary shaft 7 to shift the eccentric rotary shaft 7 with the rotary shaft 1. The core amount is manually adjusted to be large or small.

At the same time, the operation of the shaker is started after the engagement of the pulley 1a by the electromagnetic clamp mechanism 13 is released. During operation of the shaker, even if the eccentricity adjustment switch is turned on, the electromagnetic lock mechanism 11 and the electromagnetic clamp mechanism are turned on.
13 does not operate, and safety control is performed so that the operation of the shaker does not start while the electromagnetic lock mechanism 11 and the electromagnetic clamp mechanism 13 are operating. FIG. 4 shows a shaking table 15 in which a long hole 15a is inserted into the eccentric rotary shaft 7 with a ball bearing 7a interposed therebetween, and the turning force of the eccentric rotary shaft 7 is converted into right and left reciprocating motion and shaken.
As shown in (1), the sample in the container (not shown) on the shaking table 15 is shaken by reciprocating shaking along the amount of eccentricity of the eccentric rotating shaft 7 with respect to the rotating shaft 1.

Does not move in the turning direction due to the reaction force to change the amount of eccentricity of the eccentric rotary shaft 7.
