Problems solved by technology

[0006] The above-mentioned conventional hinge device also sufficiently has the functions of opening and closing, stopping, and holding of the display device (cover body), but the conventional hinge device has a problem that the number of parts is large and the structure is complicated.
Therefore, a lot of time and effort will be spent in manufacturing, and the manufacturing cost will be high, and the cost will increase. In addition, since it is necessary to provide cam parts that are fitted with each other on the cam member and the slide cam member (the above two cams), it is necessary to reduce ( miniaturization) axial size (length) is limited

Abstract

A hinge device for connecting one member and the other member in an openable and closable manner. The hinge device has a movable shaft, a first bracket non-rotatably fixed to the movable shaft and fixed to the one member, a second bracket rotatably and axially movably installed on the movable shaft and fixed to the other member, and a plate spring member formed in a curved shape, having on the top section of the curved a projection whose surface in contact with the second bracket is flat, and non-rotatably and axially movably installed on the movable shaft. The second bracket and the plate spring member are pressed to be in contact with each other and relatively rotated.

Description

technical field [0001] The present invention relates to a hinge device that connects two parts, such as a main body and a cover body of a small OA device such as a notebook personal computer and a mobile phone, a portable terminal device, and a lid of a toilet, so as to be openable and closable. Background technique [0002] In information equipment such as notebook personal computers and mobile phones, the keyboard is provided on the main body, and the display device is provided on the cover body, and the cover body provided with the display device is connected by a hinge device so that it can be opened and closed. Stop and hold at an easy viewing angle. [0003] This hinge device in the past generally has the following structure, so that the mutual axes are consistent, relatively rotatable, and a pair of cams can be approached and separated from each other. The cams rotate relative to each other, and the two cams move relative to each other along their axes to change the ...
