<Embodiment 5>
Next, a fifth embodiment of the present invention will be described with reference to FIG. FIG. 10 is a diagram showing another configuration of the vibration feeder.

FIG. 10 shows a front view of the vibration feeder according to the present embodiment. The vibration feeder in the present embodiment is different from the above-described fourth embodiment in the configuration in which the chute 10 is supported.

It will rotate at the desired position.

In the present embodiment, the second connecting members 232 and 233 are second on one side and the other side, respectively, with the first connecting member 231 sandwiched along the longitudinal direction of the chute 210 arranged as described later. It includes connecting members 232 and 233. First, one second connecting member 232 located on the right side of FIG. 13A will be described.

On the other hand, the second connecting member 232 has a substantially square plate-shaped side surface portion located along the side surface of the housing 100.

The other end side of the side surface portion of the motor 220 rotates eccentrically from the rotation shaft 221 of the motor 220. Then, since one end side of the side surface portion of one of the second connecting members 232 is supported by the spring plate member 234, it can reciprocate in the substantially horizontal direction as shown by arrow Y112. As a result, the side surface portion of one of the second connecting members 232 undergoes an elliptical motion close to the reciprocating motion in the diagonal direction as shown by the arrow Y113 in FIG. 13 (a).

In addition to this, both side surface portions of the other second connecting member 233 are connected via the spring plate member 235 on the end surface side of the housing 100. That is, one end side of the side surface portion of the other second connecting member 233 is supported by the spring plate member 235 on the base. The spring plate member 235 has the same configuration as the spring plate member 234 provided on one of the second connecting members 232 described above.

Since the spring plate member 235 has the same configuration as that provided on one of the second connecting members 232, one end side of the side surface portion of the other second connecting member 233 is indicated by the arrow in FIG. 13 (a). As shown in Y112, it is movable in a substantially horizontal direction with respect to the base portion B, that is, the base. However, in the present embodiment, the spring plate member 235 is slightly tilted from the direction perpendicular to the base.

Then, since one end side of the side surface portion of the other second connecting member 233 is supported by the spring plate member 235, it reciprocates in the substantially horizontal direction as shown by arrow Y112. As a result, the side surface portion of the other second connecting member 233 undergoes an elliptical motion close to the reciprocating motion in the diagonal direction as shown by the arrow Y113 in FIG. 13 (a).

Then, as described above, since one second connecting member 232 and the other second connecting member 233 are connected to the same first connecting member 231, it is connected to one end side of one second connecting member 232. The other end side of the second connecting member 233 moves in the same direction in the horizontal direction, that is, in the left-right direction of FIG. 13A.

Further, as shown in FIG. 14, a table 350 is provided in the vibration applying device having the above-described configuration by inserting it between the upper part of the second connecting member 232 and 233 and the chute 210. The table 250 has a connecting hole 232b formed on one end side of both side surface portions of one second connecting member 232 and a connecting hole 233b formed on one end side of both side surface portions of the other second connecting member 233, respectively. Supports 251,252 extending upward are pivotally supported, and a table 250 is provided at the upper end of the supports 251,252. Then, the chute 210 is fixedly provided on the upper surface of the table 250.

One end side of the connecting member 232 can be reciprocated in the substantially horizontal direction. At this time, similarly, one end side of the other second connecting member 233 and the base portion B of the housing 100 are illustrated with reference to FIG. 1 in the above-described first embodiment instead of the above-mentioned spring plate member 235. It may be connected via a link member (link mechanism) as shown by reference numeral 14 or a link mechanism composed of a plurality of link members. In this case, the link member having a predetermined length is rotatably connected to one end side of the other second connecting member 233 and the base portion B of the housing 100, respectively, so that the other second connecting member 233 is rotatably connected to the other second connecting member 233 as described above. One end side of the connecting member 233 can be reciprocated in the substantially horizontal direction. And even with the above configuration, the chute 210 can be moved as shown by the arrow 114 in FIG.
