It is assumed that the refrigerator is stored at a predetermined position in the refrigerator compartment (2). When the refrigerator compartment door (4) is opened, the contact point (39)
(40) closes. Next, switch (
26), the microcomputer (42) energizes the coil (43) and closes the switch (36), causing no current to flow in the upward direction in FIG. 5 to the motors (14) and (15). As a result, the motors (14), (ts) rotate, the binions (8), (8) rotate in the direction of pulling out the shelf (5), and the shelf (5>) is pulled out to the front side.

棚(5)は冷蔵室(2)内の所定の位置に収納される。Next, when the switch (27) is operated from this state, the microcomputer (42) energizes the coil (44) and closes the switch (37). This allows the motor (14)
, (15) is supplied with a current in the downward direction in Fig. 5,
The motors (14) and (15) rotate in the opposite direction to the above and move the shelf (5).
) is retreated and stored in the refrigerator compartment (2). When the stopper (20) comes into contact with the microswitch (23), the microcomputer (42) switches to the fill (44).
Turn off the power to +I-, open the switch (37), and stop the motors (14) and (15). In this state, the shelf (5) is stored at a predetermined position within the refrigerator compartment (2).

動して衝突することはない。In the above operation, when the door (4) is closed, the contact (
38) is open, so even if you accidentally operate the switch (26), no current will flow to the motors (14) and (15).Therefore, the shelf (5) will move forward when the door (4) is open. They don't move and collide.
