DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a couchtop extension device used to extend the space used on a couchtop such as a table.

[0002]

2. Description of the Related Art With the spread of computers, the number of cases in which OA equipment such as a computer is permanently installed on a table has increased.
With a table of m, the depth is insufficient and it is difficult to perform proper input work, and peripheral devices such as a keyboard and a mouse take up space on the top board, so space used for reading and writing is required. There are problems such as loss. Therefore, the development of a slide top plate that can be used with a keyboard, a mouse, and the like mounted thereon is being expanded by expanding the use space on the top plate. As a conventional technique, a keyboard is stored in a dedicated drawer provided on the lower surface of a table or the like, and the keyboard is slid forward when used to perform input work on the dedicated drawer. There is a device in which a slide-type auxiliary top plate is installed on the lower surface of the device and is slid forward during use, and then a keyboard is placed on the auxiliary top plate.

[0003]

However, in the former case, a keyboard is housed in a dedicated drawer, so that a normal center drawer cannot be used, and a thicker keyboard is used. If the depth of the special drawer is set in consideration of this, there is a problem that the working position is lowered for a thin keyboard. In addition, the connection between the keyboard and the main body cord must be detoured, and
Dos will be overwhelmed. In the latter case, there is no space to arrange the normal center drawer because the auxiliary top plate is installed on the lower surface of the top plate, and the work position can be kept constant regardless of the thickness of the keyboard. Thereafter, each time the auxiliary top board is stored on the lower surface of the top board, it is necessary to change peripheral devices such as a keyboard and a mouse on the top board.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a top plate expanding apparatus according to the present invention employs an auxiliary top plate as a tape.
The front end of the auxiliary top plate can be pulled out closer to the use edge of the top plate while maintaining the attached state while being attached to the upper surface of a top plate such as a bull.
