  As shown in FIG. 2, the control unit 60 is supplied with power from the power cable 24c. The control unit 60 is connected to the motor 50 by a control cable 61. The control unit 60 controls the rotation speed of the rotation shaft 51 of the motor 50 to constant speed or speed change. The input / output unit 62 of the control unit 60 includes an operation dial and a display unit.

  The rotation transmission member 70 is fixed to the upper end of the rotation shaft 51 of the motor 50 provided in a biased manner on the casing 20 via a key member 74 or the like. The rotation transmission member 70 is an inner peripheral surface of the second bearing 40. 45 and / or the surface 35 (inner peripheral surface) of the first bearing 30 (inner race ring portions 31, 41) is in contact (pressure contact or meshing). Thereby, the rotation of the rotating shaft 51 is transmitted to the second bearing 40 via the rotation transmitting member 70. Note that the rotation transmitting member 70 is made of metal or formed in a substantially disc shape with resin, and is shown in FIGS. 9 and 10. Non-slip stoppers 72 and 73 made of anti-slip rubber (nitrile rubber or fluororubber), resin, or O-ring are provided on the outer periphery of the substantially disc-shaped rotation transmission member main body 71 constituting the rotation transmission member 70. Yes.

  A through-hole 71 a that penetrates in the Z-axis direction is formed at the center of the rotation transmitting member main body 71. Further, the rotation transmission member main body 71 has grooves 71c and 71d formed around the Z axis on the outer periphery.

  As shown in FIG. 5, the rotation transmission member 70 is provided with a keyway. A key member 74 is fitted in the key groove.

  The radius L1 of the rotation transmitting member 70 is the length from the center of rotation of the rotating shaft 51 to the surface 35 as shown in FIGS. The radius L2 of the first bearing 30 is a length from the center of the inner race ring portion 31 to the inner peripheral surface. The radius L1 is smaller than the radius L2. Therefore, according to the principle of leverage (in principle, it is necessary to consider the frictional force of the rolling elements 33 and 43), compared with the case where the inner race ring portion 31 is rotated by providing a rotation shaft at the center of the inner race ring portion 31. However, the inner race 31 can be rotated with a small force.

  Specifically, the radius L1 is approximately 1/3 of the radius L2. For this reason, the inner race ring portion 31 is rotated with a force of about 1/3 compared with the case where the inner race ring portion 31 is rotated by providing a rotation shaft (not shown) at the center of the inner race ring portion 31. obtain.

  Similarly, the inner race ring portion 41 is rotated with a smaller force than when the inner race ring portion 41 is rotated by providing a rotation shaft (not shown) at the center of the inner race ring portion 41 of the second bearing 40. Can do.

  Next, the operation of the turntable 1 configured as described above will be described with reference to FIG. 1, FIG. 3, FIG. 7, and FIG. As shown in FIG. 12, an exhibit set 100 that is an object to be placed is placed on the table body 10 of the turntable 1.

  The display set 100 includes a display case 101 containing sweets for display, and a fluorescent lamp 102 disposed on the top. The fluorescent lamp 102 is connected to the power connector 28, and blinks and / or lights in a predetermined pattern, for example.

  When the rotation shaft 51 of the motor 50 rotates in a predetermined direction, the rotation transmission member 70 is synchronized.

  The rotation transmitting member 70 is in contact with the inner race ring portion 31 of the first bearing 30 and / or the inner race ring portion 41 of the second bearing 40 as described above. As a result, the inner race ring portions 31 and 41 rotate, and this rotation is transmitted to the outer race ring portion 42 via the plurality of rolling elements 43 (the rolling body 43 and the outer race ring portion 42 are connected to each other). Frictional force formed between). The rotation of the outer race ring portion 42 is transmitted to the table body 10, so that the exhibit set 100 rotates as a unit. During this rotation and rotation transmission, the table body 10 rotates at the same or lower rotation speed than the rotation speeds of the inner race ring portions 31 and 41. As described above, the table main body 10 is rotated by the frictional force formed between the rolling elements 43 and the outer raceway ring portion 42, and thus changes depending on the weight of the exhibit set 100. For example, if the weight is light, the speed is substantially constant, but if the weight is heavy, the speed is low.

  Furthermore, for example, when a predetermined load or more is applied to the table body 10 (when the user of the turntable 1 presses the exhibit set 100 with the finger F), the rolling elements 43 provided on the second bearing 40 The frictional force formed between the outer race ring portion 40 and the outer raceway ring portion 40 is canceled, and the rotational force of the rotation transmitting member 70 is not transmitted to the table body 10 (the transmission of the rotational force of the rotation transmitting member 70 is blocked). ). The table body 10 idles. It is possible to prevent failure of the user or the like and damage to the motor 50 due to the load applied to the motor 50.

  As described above, the rotation transmission member 70, the motor 50, and the rotation shaft 51 are provided with a structure that is offset (eccentric) with respect to the center of the casing 20 (table body 10) (drive source), and is small. The table body 10 can be rotated by torque. By adopting a small motor as the motor 50, it is possible to achieve power saving, cost reduction, and size reduction.

  Further, the top plate 22 of the casing 20 is a power source for pulling out a rotary shaft through-hole 22b through which the rotary shaft 51 of the motor 50 is inserted and a power cable 24a for supplying power to the placing object placed on the table body. A cable through hole 22a is formed. Thus, the through-hole through which the rotating shaft 51 passes and the through-hole through which the power cable 24a passes are formed separately. As the table body 10 rotates, the power cable 24 a does not get entangled with the rotating shaft 51.

  Further, one end of the power cable 24 a is fixed to the casing 20, and a cable fixing portion 27 having a connection terminal 26 is provided. The power cord 24d is electrically connected to the power cable 24a via the connection terminal 26. For this reason, when the object to be placed rotates together with the table body 10, the power cord 24d can rotate with respect to the power cable 24a. As a result, the power cable 24a and the power cord 24d can be prevented from being twisted with the rotation of the table body 10. Thereby, disconnection of the power cable 24a and the power cord 24d can be suppressed.

<< Second Embodiment >>
Hereinafter, a turntable 1A according to a second embodiment of the present invention will be described with reference to FIGS. For easy understanding, XYZ coordinates are set and referred to as appropriate.

  As shown in FIG. 13, the turntable 1 </ b> A does not include the above-described second bearing 40 and has a structure including a single rotation transmission member 70 </ b> A that includes a slip stopper 72 a (described later). This is different from the turntable 1 according to the first embodiment described above. This difference will be mainly described.

  The first bearing 30 </ b> A is a radial ball bearing similar to the first bearing 30. The table main body 10 is installed on the upper surface of the inner race ring portion 31 of the first bearing 30A so that the centers of the inner race ring portion 31 and the table main body 10 coincide.

  As shown in FIGS. 14 and 15, the rotation transmission member 70A includes a rotation transmission member main body 71A and a slip stopper 72A. The anti-slip 72A is provided in a groove 71c formed around the Z axis along the outer periphery of the rotation transmitting member main body 71A.

  The anti-slip 72A of the rotation transmitting member 70A is in contact with the surface 35 of the first bearing 30A (inner race ring portion 31). Furthermore, the anti-slip 72A is formed at substantially the same height in the center of the surface 35 in the Z-axis direction, and the rotational force of the rotation transmitting member 70A is efficiently applied to the inner race ring portion 31 of the first bearing 30A. introduce.

  In principle, the turntable 1 </ b> A does not idle, but it is considered that idling in a state in which the frictional force between the anti-slip 72 </ b> A and the surface 35 of the inner race ring portion 3 is eliminated is possible. Other configurations and features are basically the same as those of the first embodiment.

  As mentioned above, although embodiment of this invention was described, this invention is not limited by each said embodiment etc.

  For example, the first bearings 30 and 30A and the second bearing 40 are constituted by radial ball bearings. It is not limited to this. For example, you may be comprised from the thrust ball bearing. For example, not a ball bearing but a roller bearing or a slide bearing may be used.

  Further, the outer race ring portion 42 and the table body 10 are fixed by a stopper 44. It is not limited to this. For example, if the frictional force between the table body 10 and the outer race ring portion 42 is equal to or greater than a predetermined value, fixing means such as an adhesive or a screw may not be provided.

  Further, the rotation transmission member 70 has antiskids 72 and 73. It is not limited to this. For example, as long as the frictional force is generated between the rotation transmission member main body 71 or the rotation transmission member 70A and the first bearing 30 and / or the second bearing 40, the slip stoppers 72 and 73 are not required. Good.

  It should be noted that the present invention can be variously modified and modified without departing from the broad spirit and scope of the present invention. Further, the above-described embodiment is for explaining the present invention, and does not limit the scope of the present invention.
