Abstract

An electronic apparatus includes an image display panel that includes an image display screen to display an image on a front side; a light emitting/receiving unit that is disposed at an end of a first side of the image display panel and emits and receives light to detect a position of an object proximal to or on a front surface of the image display panel; a cover that exposes the image display screen and that includes a plate covering at least the first side of the front surface of the image display panel with a gap; and a reinforcement component that contacts the plate between the image display panel and the plate.

Claims

1. An electronic apparatus comprising:

an image display panel that includes an image display screen to display an image on a front side;

a light emitter/receiver that is disposed at an end of a first side of the image display panel and emits and receives light to detect a position of an object proximal to or on a front surface of the image display panel;

a cover that exposes the image display screen and includes a plate covering at least the first side of the front surface of the image display panel with a gap and an arm, on a rear side of the plate, extending along the first side of the image display panel; and

a reinforcement component that contacts the arm between the image display panel and the plate,

wherein the cover includes a rib at a central portion in the extending direction of the first side on a surface of the plate facing the front surface of the image display panel, the rib extends to an area along the first side on the front surface of the image display panel, and

wherein the reinforcement component includes a hole through which the rib passes.

2. The electronic apparatus according to claim 1, wherein the reinforcement component includes a first plate extending along the first side and the plate, a second plate being bent from an end of the first plate and extending to the plate, and a third plate being bent from an end of the second plate, extending along a surface of the plate, and contacting the plate.

3. The electronic apparatus according to claim 1, further comprising a reflecting surface that is disposed to correspond to another side of the image display panel other than the first side and reflects light emitted from the light emitter/receiver.

4. The electronic apparatus according to claim 1, wherein the cover is a front cover, and

wherein the electronic apparatus further comprises a rear cover that extends on a rear side of the image display panel and forms an inner space to receive the image display panel in cooperation with the front cover.

5. The electronic apparatus according to claim 1, wherein the light emitter/receiver includes a first light emitter/receiver disposed at a first end portion of the first side and a second light emitter/receiver disposed at a second end portion opposite to the first end portion of the first side.

6. The electronic apparatus according to claim 1, wherein the light emitter/receiver emits an infrared ray as the light.

7. An electronic apparatus comprising:

an image display panel that includes an image display screen to display an image on a front side;

a light emitter/receiver that is disposed at an end of a first side of the image display panel and emits and receives light to detect a position of an object proximal to or on a front surface of the image display panel;

a cover that exposes the image display screen and includes a plate covering at least the first side of the front surface of the image display panel with a gap and an arm, on a rear side of the plate, extending along the first side of the image display panel; and

a reinforcement component that contacts the arm between the image display panel and the plate,

wherein the arm extends along the first side and the surface of the plate and the arm includes;

a first surface facing the plate;

a second surface opposite to the first surface; and

a plurality of positioning bosses protruding to the second surface in the extending direction of the first side, the plurality of positioning bosses including at least a first boss and a second boss, and

wherein the reinforcement component includes a plurality of positioning holes into which the plurality of bosses are respectively inserted, the plurality of positioning holes including at least a first hole into which the first boss is inserted and a second hole into which the second boss is inserted.

8. The electronic apparatus according to claim 7, further comprising a support member that is fixed to a rear side of the arm portion opposite to the front surface of the image display panel and supports an electronic component,

wherein

the arm includes a third positioning boss protruding to the second surface,

the reinforcement component includes a third positioning hole into which the third positioning boss is inserted, and

the support member includes a fourth positioning hole into which the third positioning boss passing through the third positioning hole of the reinforcement component is inserted.
