Abstract

Provided is an image display apparatus that has: a case distinguished into a plurality of regions and has a projection port; an image display apparatus main body that projects an image from the projection port; and a controller that electrically connects to the image display apparatus main body and to an external electronic device, and is positioned so as to straddle on the plurality of regions. The case has: a first region that houses a first portion of the controller and is held by the electronic device at least at one portion of the region; a second region positioned away from the electronic device so as to sandwich the first region and houses the image display apparatus main body; and a third region positioned away from the projection port and away from the electronic device so as to sandwich the first region, and houses a second portion of the controller. Therefore, the image display apparatus can be made compact to be installed within an electronic device.

Claims

1. An image display apparatus comprising:

a case that is distinguished into a plurality of regions and has a projection port;

an image display apparatus main body that projects an image from the projection port; and

a controller that electrically connects to the image display apparatus main body and to an external electronic device, and is positioned so as to straddle on the plurality of regions, the case comprising;

a first region that houses a first portion of the controller and is held by the electronic device at least at one portion of the region;

a second region that is positioned away from the electronic device so as to sandwich the first region and houses the image display apparatus main body; and

a third region that is positioned away from the projection port and away from the electronic device so as to sandwich the first region, and houses a second portion of the controller.

2. The image display apparatus according to claim 1, wherein the second region of the case rotates in a direction perpendicular to a direction to which the image display apparatus projects an image.

3. The image display apparatus according to claim 1, wherein the projection port is provided in the second region close to a surface opposite to an electric device side of the case, away from the first region.

4. The image display apparatus according to claim 1, wherein the case comprises:

an air inlet port;

an exhaust port; and

a cooling air passage formed by connecting the air inlet port and the exhaust port within the case, and wherein at least one portion of a heat dissipating portion of the image display apparatus main body is positioned in the cooling air passage.

5. The image display apparatus according to claim 4, comprising:

an air blower provided in the cooling air passage and is housed in the third region, and wherein the air inlet port is provided in a direction perpendicular to a surface direction of the air blower.

6. The image display apparatus according to claim 5, wherein the air blower is provided in the third region close to a surface opposite to an electric device side of the case, away from the first region.

7. An image display apparatus comprising:

a case that is distinguished into a plurality of regions and has a projection port, an air inlet port, and an exhaust port;

an image display apparatus main body that projects an image from the projection port;

a cooling air passage that is formed by connecting the air inlet port and the exhaust port in the case;

a heat dissipating portion at least a portion of which is positioned in the cooling air passage and dissipates heat of the image display apparatus main body and;

a controller that electrically connects to the image display apparatus main body and to an external electronic device, and is positioned so as to straddle on the plurality of regions, the case comprising;

a first region that houses a first portion of the controller and is held by the electronic device at least at one portion of the region;

a second region that is positioned away from the electronic device so as to sandwich the first region, rotates in a direction perpendicular to a direction to which an image is projected, houses the image display apparatus main body, and has the projection port close to a surface opposite to an electric device side of the case, away from the first region; and

a third region that is positioned to form a key shape together with the first region so as to cover one corner of the second region, and houses a second portion of the controller.

8. The image display apparatus according to claim 7, comprising:

an air blower provided in the cooling air passage and is housed in the third region, and wherein the air inlet port is provided in a direction perpendicular to a surface direction of the air blower.

9. The image display apparatus according to claim 8, wherein the air blower is provided in the third region close to a surface opposite to an electric device side of the case, away from the first region.

10. An image display apparatus comprising:

a case that is distinguished into a plurality of regions and has a projection port, an air inlet port, and an exhaust port;

an image display apparatus main body that projects an image from the projection port; and

a controller that electrically connects to the image display apparatus main body and to an external electronic device, and is positioned so as to straddle on the plurality of regions, the case comprising;

a first region that houses a first portion of the controller and is held by the electronic device at least at one portion of the region;

a second region that is positioned away from the electronic device so as to sandwich the first region, and houses the image display apparatus main body; and

a third region that is positioned to form a key shape together with the first region so as to cover one corner of the second region, and houses a second portion of the controller.
