A control outlet 1 which can be turned on and off by the switch 3 is provided on the back of the box body 1.
0 is provided, and the lighting fixture 11 is connected to the control outlet 10.
The power supply is connected to a plug 12 so that the switch 3 can turn on and off the lighting fixture 11.
Here, the breaker 9 is for limiting the total power supplied to all the outlets 5 and 5 and the control outlet 10 provided in the box body 1.

The desk shelf B is a lower shelf 1 in this embodiment.
Although the stack 3 and the upper shelf 14 can be connected and separated from each other, they may be integrated. The lower shelf 13 is provided with a back plate 16 between the rear portions of both side plates 15, 15, and with a middle partition plate 17 attached to an intermediate portion between the both side plates 15, 15, and one side plate 15 and the middle partition plate 17.
And a shelf plate 19 is detachably mounted between the other side plate 15 and the middle partition plate 17. The upper shelf 14 is provided with both side plates 20 and 2.
0, a back plate 21 is provided between the rear portions,
The upper shelf plate 22 is fixed between 20, and the upper shelf plate 22 is
When the main stand 18 is separated from the lower shelf 13 and used independently, a support member 23 which is attached to the main stand 18 and serves as a back contact and a side contact is detachably attached.

The luminaire 11 has a main body 11A attached to the back side of the desk shelf B, and an arm extending from the main body 11A and extending forward from a notch (not shown) of the back plate 21 of the upper shelf 14. The lamp 11C is supported by 11B, and the lamp 11C is disposed along the lower front edge of the upper shelf 22. The lighting fixture 11 can be used independently of the desk shelf B separately. The plug 12 of the lighting fixture 11 is connected to the control outlet 10 of the power supply device C as described above.

In this embodiment, the power supply device C is mounted on a side surface of the partition plate 17 of the lower shelf 13 and at a position along the lower surface of the shelf plate 19.
The partition 17 is provided with a space between the partition 24 and the top plate 24 of the learning desk A. Even when the power supply device C is attached to the partition 17, the space between the box 1 and the box 1 of the power supply device C is maintained.

In a state in which a plug 7 for supplying power to an electric device used on the top plate 24 of the learning desk A or on the desk shelf B is connected to A, a cord 7A extending from the plug 7 is forwardly connected to the desk shelf B from the desk shelf B. To the top plate 2
4 can be used widely. For example, when a personal computer is installed on the top plate 24 of the learning desk A, there is no fear that the code 7A hits the monitor, and there is no restriction on the position where the personal computer is installed. Also, the shelf 19 of the lower shelf 13 is removed, and the space of the PC
Even when a monitor such as an RT is installed, since the plug 7 is oriented in the direction of the normal to the inclined surface 4, a sufficient installation space can be secured between the partitioning plate 17 and the side plate 15. Further, since the outlet 5A of the outlet 5 is formed on the inclined surface 4, there is an advantage that the plug 7 can be easily inserted and removed.

In the above-described embodiment, the power supply device C is mounted on the partition plate 17 which is a vertical plate surface of the desk shelf B. However, it is also possible to mount the power supply device C on the inner surface of the side plate 15.
It is also possible to attach the contact surface 6 to the horizontal plate surface such as the lower surface of the panel 9 and detachably attach the operation panel surface 2 to the front.

Further, as shown in FIG. 6, the desk shelf B is removed from the top plate 24 of the learning desk A, and the book 18 and the lighting equipment 11 are separated and installed on the top plate 24 for use. , The power supply device C is also removed from the desk shelf B,
It is also possible to use the contact surface 6 mounted on it. Here, it is preferable to attach the book 18 and the power supply device C to the top plate 24 by using the fixtures 26 that fixed the desk shelf B to the top plate 24 of the learning desk A. The fixing tool 26 includes a clamp portion 26 </ b> A for clamping an edge of the top plate 24.
And a mounting plate 26B perpendicular to the
Is attached to the edge of the top plate 24, and the back of the box body 1 of the main stand 18 or the power feeding device C is screwed to the attachment plate 26B.

The power supply device C according to another embodiment shown in FIGS. 7 and 8 has the box body 1 without the step 8.
The switch panel 3 and the breaker 9 are provided on the operation panel surface 2, and the insertion surface 5 A of one or more outlets 5 is provided on the inclination surface 4.
Is provided. In this case, the mounting position of the box body 1 is set further rearward than in the above-described embodiment so that the cord 7A of the plug 7 connected to the outlet 5A of the outlet 5 does not interfere. .

In this embodiment, an example is shown in which the power supply device C according to the present invention is applied to a learning desk A with a desk shelf as learning furniture. However, the present invention can also be applied to a writing desk upper shelf or the like. Of course, it is also possible to apply to other learning furniture and general furniture.
