In detail, the groove 34 allows the motor 31 and the pinion 32 to be accommodated when the shelf 20 reaches the lowered position where the shelf 20 reaches the lower side of the inner case 10. This is to perform the function so that (32) does not interfere with the operation of the shelf.

The operation of the lathe lifting device by the configuration as described will be briefly described.

When the user wants to take out the container 15 or 16, power is applied to the motor 31 by a predetermined input signal such as a user's instruction or opening a door. When power is applied to the motor 31 to rotate, the pinion 32 rotates, and when the pinion 32 rotates, the shelf 20 rises along the rack 33 engaged with the pinion 32.

As such, when the shelf 20 is raised, the accommodation containers 15 and 16 placed on the upper side of the shelf 20 are also raised, so that the user can take out the accommodation containers 15 and 16 more conveniently. Of course.

In addition, the rack 33 is formed in the vertical direction on the side of the inner case 20 to be engaged with the pinion (32).

In addition, the lower surface of the shelf 20 is formed with a solenoid 36 and a projection 37 which is operated back and forth by the solenoid 36. The protrusion 37 is reciprocated in the front and rear direction by the solenoid 36, and the end of the protrusion 37 is fitted to the interdental space of the rack 33.

In addition, the bottom surface of the inner case 10 is provided with a groove 34 in which the motor 31 and the pinion 32 are placed, so that the motor 31 and the pinion 32 when moved to the lower end of the shelf 20. ) Is accommodated in the groove 34, so as not to obstruct the lowering of the shelf (20).

In addition, a guide rail 35 extending in a vertical direction is formed at a predetermined position on a wall surface of the inner case 10, and a protrusion having any shape in contact with the guide rail 35 is formed at one side of the shelf 20. By being provided, when the shelf 20 is moved upwards, the shelf 20 may not swing. In the drawings, the mall guide rails 35 are described as being formed on opposite sides thereof, but the present invention is not limited thereto and may be provided in various cases.

Referring to the operation of the shelf lifting device, first when the external power is applied to the motor 31 by the user's instruction or a predetermined external input signal, the shelf 20 is raised by the rotation of the pinion (32). Of course, the pinion 32 is rotated in reverse, the shelf 20 can also be moved in the downward direction. At this time, since the movement of the shelf 20 can be supported in both directions by the guide rail 35, the shelf 20 can be moved in a state where the horizontal is maintained without swinging.

After the shelf 20 reaches a predetermined position, the application of power to the motor 31 is stopped, the power is applied to the solenoid 36, and the power is applied to the solenoid 36. Pushed toward the end, the end of the protrusion 37 is fixed to the interdental space of the rack 33. In this state, the shelf 20 is not pushed downward even when the power supply of the motor 31 is cut off, so that the position of the shelf 20 is firmly fixed.

Since the position of the shelf 20 can be fixed by a device consisting of the solenoid 36, the projection 37, and the rack 33, such a device may be referred to as a shelf brake.
