  In the above-described desk apparatus 1 with a lift top plate, since the connector 16 is provided with an outlet capable of inserting a plug of an electric appliance from the outside of the connector 16, for example, a personal computer placed on the lift shelf 15 And so on can be plugged into an outlet provided on the connector 16 so that an appliance such as a PC placed on the elevating rack 15 can be made available at any time. it can.

  In the desk apparatus 1 with the lift top plate, when the motor 36 is driven, the lift body 5 is lifted. Therefore, the elevating body can be easily moved up and down.

  In the desk apparatus 1 with the lift top plate, since the lift body 5 is arranged to lift and lower the through hole 4a surrounded by the top plate 4, when the lift body 5 is at the retracted position, The table-top 4 makes it difficult for the user to see the placed electric appliances such as a personal computer and a telephone. Therefore, the user can easily obtain a feeling of use as a normal desk device without the elevating body 5 when the elevating body 5 is lowered to the retracted position. Furthermore, when the user is seated around the top 4, the elevator 5 does not exist at the foot of the user, so it is easy to provide a seat so as to surround the top 4.

  The lift top-equipped desk apparatus 1 described above is an embodiment of the present invention, and the specific configuration thereof can be appropriately changed without departing from the scope of the present invention. Hereinafter, the modification of the above-mentioned embodiment is explained.

  Although the said desk apparatus 1 with a lift top plate was equipped with the raising / lowering mechanism 6 which raises / lowers the raising / lowering body 5, the raising / lowering mechanism 6 may be abbreviate | omitted. In this case, the user can manually adjust the height of the elevator 5. For example, the elevator rack 15 can be fixed to the leg 2 at the position where the elevator body 5 is at the retracted position and the raised position.

  Furthermore, the motor 36 of the lifting mechanism 6 may be omitted. In this case, for example, an operation member for manually rotating the shaft 24 is provided, and the elevating rack 15 can be fixed to the leg 2 at the position where the elevating body 5 is at the retracted position and the raised position.
