Therefore, by rotating the first rotating shaft 11 and rotating the first rotating plate 14, the movement is transmitted to the panel 21 via the first eccentric shaft 15, and the panel 21 rotates. ing. Note that the eccentric distance between the first rotating shaft 11 and the first eccentric shaft 15 and the eccentric distance between the rotating shaft 18 and the eccentric rotating shaft 19 are adjustable.

Further, a second bearing body 23 is disposed on the other end in the width direction on the base 1, and a second rotating shaft 24 whose lower part protrudes into the base 1 is rotatable within the second bearing body 23. is supported by. A pulley 25 is fixed to the lower end of the second rotating shaft 24, and a belt 26 is stretched between the pulley 25 and the upper output pulley 8 of the electromagnetic clutch brake 5. The output is transmitted to the second rotating shaft 24. Further, the upper end of the second rotating shaft 24 protrudes above the second bearing body 23, and a second rotating disc (second rotating body) 27 is fixed at the center of the upper end of the second rotating shaft 24. Above is a second rotating shaft eccentric to the second rotating shaft 24.
An eccentric shaft 28 is rotatably provided. Furthermore,
The upper part of the eccentric shaft 28 projects upward through a through hole 29 formed in the lower frame 21, and its tip is rotatably attached to one end of the crank arm 30. Note that the eccentric distance between the second rotating shaft 24 and the second eccentric shaft 28 is adjustable. Although not shown, the upper end of the eccentric shaft 28 is rotatably supported by a movable body disposed in a long hole bored in one end of the crank arm 30 so as to be movable in the longitudinal direction. At the same time, the movable body is fixed at a predetermined position by a fixing bolt. Furthermore, the crank arm 30 is formed so that it can be separated at a separation portion 31.

Further, oil stands 32, 32 are fixed to the four corners of the panel (lower frame) 21, respectively, and as shown in FIG.
A panel (upper frame) 36 to which a culture container container 35 is attached is fixed to sliding support columns 34, 34 which are slidably attached to a sliding shaft 33 disposed in the container 2. The upper end of the pin 38 is rotatably attached to a support plate 37 fixed to the lower surface of the panel 36, and the pin 38
The lower end of the crank arm 8 is rotatably fitted into a hole provided at the other end of the crank arm 30. Therefore, by rotating the second rotating shaft 24, the second rotating plate 27
By rotating the panel 3, the movement is transmitted to the panel (upper frame) 36 via the second eccentric shaft 28, the crank arm 30, and the pin 38.
The sliding support columns 34, 34 fixed to the sliding shaft 3

Since the shaking culture apparatus of this embodiment has the above configuration, by operating the motor 2 and setting the electromagnetic clutch brake 5 so that the power input from the motor 2 is output from the lower pulley 7, the motor can be operated. The rotation of the second shaft 3 is transmitted to the first rotating shaft 11 by the electromagnetic clutch brake 5, and the first rotating plate 14 rotates together with the first rotating shaft 11. Therefore, this causes the lower panel 21 to rotate, and the oil stands 32, 32, sliding support columns 34, 34 and the upper panel 36 arranged on this panel 21 to be integrated with the lower panel 21. It rotates. In this case, the upper pulley 8 of the electromagnetic clutch brake 5 does not rotate, and therefore the second rotating disk 27 does not rotate, so the upper panel 36
Since the motion from the second rotating disk 27 is not transmitted, it only rotates together with the lower panel 21, and therefore the culture container accommodating body 35 attached to the upper panel 36 does not rotate. Then, rotational shaking culture is performed. Note that when performing rotary shaking culture, the degree of freedom of the panel 36 can be increased by separating the crank arm 30 at the separation part 31, or the upper panel 3
6 is fixed to the lower panel 21, and the stopper in the oil stand 32 stops the sliding shaft 33 in the oil stand 32, thereby preventing rotational fluctuation of the container 35. In addition,
By adjusting the rotational speed of the motor 2 and the distance between the center of the disk 14 and the eccentric shaft 15, the rotation cycle and rotation radius of the container 35 can be made as desired.

Further, by operating the motor 2 and setting the electromagnetic clutch brake 5 so that the power input from the motor 2 is output from the upper pulley 8, the rotation of the shaft 3 of the motor 2 is controlled by the electromagnetic clutch brake 5. The second rotation plate 27 rotates integrally with the second rotation shaft 24, thereby causing the upper panel 36 to reciprocate from side to side in FIG. In this case, the lower pulley 7 of the electromagnetic clutch brake 5 does not rotate and therefore the first rotating disk 14 does not rotate, so that the upper panel 36 is affected by the movement from the first rotating disk 14, i.e. the lower panel 21 is not transmitted, the upper panel 36 only reciprocates left and right by the movement of the second rotating disk 27, and therefore the culture vessel storage attached to the upper panel 36 The body 35 reciprocates from side to side to perform horizontal reciprocating shaking culture. Note that when performing reciprocating shaking, the electromagnetic brake 16 is activated to fix the armature 16b to the stator 16a to prevent the first rotation shaft 11 from rotating, thereby reducing the vibration of the reciprocating motion of the container 35. It can be prevented. Furthermore, the rotation speed of the motor 2 is adjusted, and the eccentric shaft 2 at the center of the disk 27 is adjusted.
By adjusting the distance from the container 8, the reciprocating cycle and amplitude of the container 35 can be made as desired.

Therefore, according to the above-mentioned shaking device, by operating the electromagnetic clutch brake 5, the culture container container 35 can be rotated or reciprocated with a single touch, and the culture container container 35 can be rotated and horizontally moved while the container 35 is mounted. It is possible to switch between reciprocating shaking, and the number of cycles and amplitude can be easily adjusted, so that desired shaking conditions can be set very easily. In addition, by disposing a connecting fixing member 39 and fixing the upper panel 36 to the lower panel 21, vibration in the rotational movement is prevented. By fixing the oscilloscope, it is possible to prevent fluctuations in the reciprocating motion, so that each motion is performed extremely precisely as set. Furthermore, by using not only a flask type culture container container 35 but also a test tube type type, it is also possible to carry out test tube shaking culture.

In the above-described embodiment, the oil stand 32 was used as the linear motion induction mechanism, but a linear motion induction mechanism having any other suitable structure may be used. Further, various changes may be made to other configurations without departing from the gist of the present invention.

Effects of the invention As explained above, the shaking culture apparatus according to the invention can switch between rotary shaking and horizontal reciprocating shaking very easily with one touch by simply switching the electromagnetic clutch brake, and does not require troublesome operations. It is possible to switch between rotation and reciprocating motion during culture, and it is possible to easily set various culture shaking conditions. Furthermore, the device of the present invention is capable of horizontal reciprocating shaking and rotary shaking as described above, and has multiple functions.
It also has the advantage of being relatively simple in structure and can be manufactured at low cost.
