Abstract

An electronic device of the present invention is an electronic device including a box-shaped casing, a liquid crystal monitor 2 that is disposed on a front face 1a of the casing and on which visual information converted from an information signal can be displayed, and operation buttons 3 disposed near the liquid crystal monitor 2. A peripheral projection 11 projecting in the direction perpendicular to the front face 1a is provided on a peripheral edge portion of the front face 1a. The height of the peripheral projection 11 in the perpendicular direction is formed so as to be greater than the height of the operation buttons 3 with respect to the front face 1a. With this configuration, erroneous operation of the operating portion caused by the self-weight of the device can be prevented.

Claims

1. An electronic device comprising:

a casing that has been formed to be box-shaped comprising a front casing and a back casing;

a display unit that is disposed on a front main face of the front casing and on which visual information converted from an information signal can be displayed;

a main operating unit that is disposed on the front main face provided with the display unit;

a sub-operating unit that is disposed on the back casing; and

a surrounding projection that is formed around the sub-operating unit in a projecting manner in a direction perpendicular to a back main face of the back casing parallel to the front main face,

wherein two said sub-operating units are respectively disposed as a pair close to a pair of end sides facing each other on the back main face.

2. The electronic device according to claim 1,

wherein the sub-operating unit comprises a projecting portion near a central portion of an operating surface for operating the sub-operating unit, the projecting portion being formed higher than the operating surface.

3. The electronic device according to claim 1,

wherein the surrounding projection comprises a top portion formed so as to be higher than the operating surface of the sub-operating unit with respect to the back main face.

4. The electronic device according to claim 2,

wherein the surrounding projection comprises a top portion formed so as to be higher than the projecting portion.

5. The electronic device according to claim 1,

wherein a same function is assigned to the sub-operating units disposed as a pair.

6. The electronic device according to claim 1,

wherein the back casing comprises a recessed surface portion sunken in a depressed manner with respect to the back main face that is formed on a substantially central portion of the back main face facing the front main face.
