Abstract: A housing device 100 for plural components that can be arrayed one on top of another includes a support 101 for housing the components on introducing the latter into the support, and a locking unit 102 configured for preventing the components housed in the support 101 from being moved out of the support 101. The housing device 100 also includes a base member 103 having an unlocking support 101 which is adapted to release the state of the locking unit 102 prohibiting the movement of the components housed in the support 101. The components to be housed are usually locked by the locking unit 102. The locked state of the components is established by simply placing the components into the support and is released by the unlocking support 101. A larger number of the components can be housed on top of each other if so desired.
