The input unit 40 can input part information such as a part name, a part number, a unit weight of a part, an address (IP) of a part storage drawer, and an appropriate weight by an operator.

The part information stored in the input unit 40 is stored in the memory unit 50. The memory unit 50 stores part information stored by an operator and is connected to the main controller 30 to transmit part information.

The main controller 30 is connected to the manager screen 60. The manager screen 60 is a general display, and a detailed description thereof will be omitted. When the status of all parts is displayed on the manager screen 60, the quantity of goods received or shipped is displayed at the time of goods receipt or shipment, and the current price of the parts is displayed.

4 is a front view showing a parts storage box constituting another embodiment of the present invention.

As shown in FIG. 4, the parts storage box 10 has a rectangular parallelepiped shape, and a plurality of insertion grooves 12 are formed in the front portion thereof. The parts storage box 10 is generally a storage unit capable of storing a plurality of parts for each type, and a detailed description thereof will be omitted. The part storage box 10 serves to store a plurality of parts.

A parts storage box 15 is provided inside the parts storage box 10. The component storage box 15 has a hollow hexahedron shape, and is formed in a box-shaped open top.

The component storage box 15 is mounted inside the insertion groove 12 of the component storage box 10. The insertion groove 12 has a longer vertical length than the component storage box 15. The component storage box 15 is inserted into the insertion groove 12 and a component can be loaded or unloaded through the upper space of the component storage box 15.

That is, when the worker takes the part out of the part storage box 15, the inside part can be put in or out through the space above the part storage box 15 as shown in FIG.
