Is stopped at the upper part of the pressure receiving surface 58 by being prevented from further ascending by the upper end of the elongated hole 78.
The clockwise rotation of No. 2 is further prevented, and the lower protrusion 48 can support the second-stage fine can C2.

In the sales state of the return state, when the suction force of the solenoid 62 is lost, the holding member 66 moves downward by the urging force of the spring 82, and the moving shaft 76 that has entered the recess 52 of the temporary fixing piece 42. Moves downward. The support piece 24 rotates counterclockwise by the urging force of the spring 38 after dropping the lowermost can C2. Then, the moving shaft 76 is located on the front surface of the protruding portion 30 of the support piece 24, and prevents the clockwise rotation, thereby fixing the support piece 24.

The temporary fixing piece 42 that has lost support of the moving shaft 76 is rotated clockwise by the pressing force of the second-stage fine can C2 to drop the second-stage fine can C2 from the support portion 28. Thus, the system returns to the sales standby state.

In the sold-out state (see the state indicated by the two-dot chain line in FIG. 13), when the sold-out lever 84 is sold out except for the lowermost thin can C 2, the sold-out lever 84 is rotated by the urging force of the spring 102. Then, the switch unit 100 of the microswitch 98 is pressed to output a sold-out signal.

In the commodity discharging apparatus 10 having the above-described structure, the temporary fixing piece 42 is used for both the thick can C1 and the thin can C2.
, The switching can be performed automatically, and the administrator does not need to switch. Further, even if the thick can C1 or the thin can C2 is put in and sold out, the sold-out detecting lever 8 can be used.
No. 4 can always detect the sold out.

In the above-described embodiment, the moving shaft 76 that moves upward is used in the above-described embodiment in order to promote the rotation of the temporary fixing piece 42 in the selling state. Instead, the urging force of the spring is used. You may. That is, the rear part of the temporary fixing piece 42 and the lower part of the frame body 14 are connected by a spring so that the upper projection 46 is always rotated upward. Thereby, the can can be supported in the sales state.
