While moving away from to the position opposite the article exit 3,
The push rod 133 pushes up the lid-shaped bottom plate 103, and the lid-shaped bottom plate 103 is inclined.

Therefore, if it is desired to avoid the inclination of the lid-like bottom plate 103 depending on the type of the article, it is recommended that a small motor be attached to the arm 58 and the push rod 133 be moved in and out by the operation of the motor.

In this embodiment, the guide pins 107 and 108
The shape of a square pyramid was adopted. The quadrangular pyramid guide pins 107 and 108 as in the present embodiment have excellent stability against lateral sway, and are particularly suitable for a configuration in which a cam is used in a transport apparatus outside the warehouse as in the present embodiment.

In this embodiment, the door 12 of the microwave 20
A part of the tray rack 121 provided at 0 is cut out to form an arm passage portion 123. The size of the arm passage portion 123 is desirably designed to be as small as possible in order to prevent the article 2 on the tray 100 from falling, but it is necessary to pay attention to the position of the notch. is there.

That is, the position of the notch is
It is desirable to provide it around the corner at the farthest position from the swing center of the door 120.

The reason is that the tray 100 is
When the microwave oven 20 is inserted into and removed from the microwave oven 20, an inertial force in the opening and closing direction of the door 120 acts on the article 2 on the tray 100, and the inertia force often causes the article 2 to move. is there. Of course, door 120
The article 2 may move in the direction away from the center of swing due to the centrifugal force generated when opening and closing the unit, but the frequency of occurrence is far less than that due to the inertial force and can be ignored in practical use.

In the embodiment described above, a refrigerator is illustrated as an example of the storage. However, the present invention is not limited to this embodiment, and the storage may be a simple box having no refrigeration capacity.

The processing device is not limited to the microwave oven as in the present embodiment, but may be a device using an open flame or a device for pouring hot water.
