[0003]

In this conventional desk with shelves, the upper shelf removed according to the change from the first use mode to the second use mode or the third use state is directly used as the knee of the desk body. By supporting it in the horizontal position on the back side of the insertion space,
Because the upper shelf can be reused as a storage shelf,
There is no need to discard the upper shelf removed from the desk with the change of the use form, and there is an advantage that wasteful use of resources can be suppressed. However, since the upper shelf is directly laid in the kneeling space of the desk main body, the maximum left and right length of the upper shelf is slightly smaller than the distance between the opposing surfaces in the left and right direction of both side plates of the desk main body forming the kneeling space. It must be configured to be small, and the left and right maximum length of the lower shelf must be configured to be smaller than the distance between the opposing surfaces in the left and right direction of both side plates of the desk body by the same dimension. As a result, it becomes a big restriction on the form of the desk body and the lower shelf and the upper shelf,
Since the form of reuse of the upper shelf is only one form used for the storage shelf in the knee space of the desk body, there is no room for the user to select.

Further, as a method of solving the above-mentioned conventional inconvenience, the present inventor has developed a desk with a shelf as shown in FIGS. The upper shelf C of this desk with shelves,
