Abstract

An electronic device of the present invention includes a plate-shaped stand member rotatably attached to a back surface of the housing, and a holding member capable of holding the stand member at a predetermined upright support angle with respect to the back surface of the housing, wherein the holding member regulates the rotation of the stand member at a predetermined rotation angle exceeding the upright support angle from a stored position with respect to the housing. With such a configuration, an electronic device such as a portable television can be provided, in which a stand is unlikely to be broken even when the electronic device topples over and a pressing force further is applied thereto.

Claims

1. An electronic device, comprising:

a housing;

a stand member rotatably attached to a back surface of the housing by a spindle, the stand member having a lower surface which is inclined with respect to a line orthogonal to the front surface of the housing; and

a holding member configured to hold the stand member at a first protruding position where the stand member has been rotated a first angle of approximately 90 degrees from the housing and a second protruding position where the stand member has been rotated a second angle greater than the first angle from the housing,

wherein when the holding member holds the stand member at the first protruding position, the housing is placed in an upright posture by the lower surface of the stand member,

the holding member includes a regulating portion configured to regulate further rotation of the stand member at angles exceeding the second angle associated with the second protruding position; and

wherein an end portion of the stand member abuts on the regulating portion of the holding member and is rotated between a plate spring portion and the regulating portion of the holding member in said second protruding position, such that the end portion of said stand member presses and elastically deforms said plate spring portion of the holding member.

2. The electronic device according to claim 1, wherein the stand member is formed of a flexible material.

3. The electronic device according to claim 1, wherein the holding member is configured to provide a force to the spindle when the holding member holds the stand member at the first and second protruding positions while a pressing force is applied to the housing in a direction from the front surface to the back surface, wherein the force provided by the holding member to the spindle is greater at the first protruding position than at the second protruding position.

4. The electronic device according to claim 1, wherein the second angle associated with the second protruding position is approximately 135 degrees from the housing.

5. An electronic device, comprising:

a housing;

a stand member rotatably attached to a spindle on the back surface of the housing, the stand member having a lower surface which is inclined with respect to a line orthogonal to the front surface of the housing; and

a holding member including;

a plate spring portion configured to engage with an end portion of the stand member and hold the stand member at a first protruding position where the stand member has been rotated a first angle of approximately 90 degrees from the housing; and

a regulating portion configured to engage with the end portion of the stand member and hold the stand member at a second protruding position where the stand member has been rotated a second angle greater than the first angle from the housing and prevent further rotation greater than the second angle,

wherein when the holding member holds the stand member at the first protruding position, the housing is placed in an upright posture by the lower surface of the stand member; and

wherein the end portion of said stand member presses and elastically deforms the plate spring portion of the holding member when the stand member is at the second protruding position.

6. The electronic device according to claim 5, wherein the second angle associated with the second protruding position is approximately 135 degrees from the housing.

7. The electronic device according to claim 5, wherein the holding member is configured to provide a force to the spindle when the holding member holds the stand member at the first and second protruding positions while a pressing force is applied to the housing in a direction from the front surface to the back surface, wherein the force provided by the holding member to the spindle is greater at the first protruding position than at the second protruding position.
