Abstract

A hand-held device is a portable device configured to be attached to and detached from a metal board, and includes a casing and a magnet disposed inside the casing so as to be attracted to the metal board via an attachment face of the casing. The hand-held device further includes an urging element for urging the magnet so that the magnet moves in a direction away from the attachment face when the casing is detached from the metal board.

First claim

What is claimed is:

1. A portable hand-held device configured to be attached to and detached from a metal board, comprising:
a casing including:
a front attachment surface adapted to be attached to the metal board; and
an operation panel for a machining tool, the operation panel being located on a side of the casing opposite to a side of the casing where the front attachment surface is;

a magnet disposed inside the casing, the magnet being disposed between and spaced from both the front attachment surface and the operation panel of the casing when the metal board is detached from the casing, the magnet being attracted to the metal board via the front attachment surface of the casing;
an urging element configured to urge the magnet so that the magnet moves in a direction away from the front attachment surface when the casing is detached from the metal board; and
a guide portion provided inside the casing and configured to surround a movement path of the magnet,
wherein the urging element is a spring arranged inside the guide portion.

2. The hand-held device according to claim 1 , wherein urging force of the urging element is smaller than attraction force of the magnet.

3. The hand-held device according to claim 1 , wherein the guide portion is configured to surround an entire periphery of the movement path of the magnet.

4. The hand-held device according to claim 1 , wherein the hand-held device is an operation device for operating the machining tool.

5. The hand-held device according to claim 1 , wherein the urging element exerts a resilient bias on the magnet in the direction away from the front attachment surface.

6. The hand-held device according to claim 5 , wherein the magnet is enclosed by the casing and restricted from moving forward of the front attachment surface.
