Description

  The present invention relates to an imaging device having a pivotable display device, and more particularly to a holding configuration of the display device.

  Conventionally, in an imaging apparatus such as a digital camera, it has a live view function capable of displaying a signal output from an imaging element on a display device provided on the appearance of the imaging apparatus and confirming composition and exposure before shooting. There is something. Among such imaging devices, there are some in which the display device is rotatably held relative to the imaging device main body in order to ensure visibility of the display device at extremely low angles and high angles. In order to rotatably hold the display device, a configuration has been proposed in which the display device and the hinge mechanism are fastened and the hinge mechanism is fixed to the imaging device main body.

  However, in the prior art disclosed in the above-mentioned Patent Document 1, since the metal holding member is required, the imaging device becomes heavy, and the cost of the holding member is increased. In addition, since the hinge mechanism and the holding member are not in direct contact with each other but only connected via screws, the electrical connection between the hinge mechanism and the ground of the chassis portion is weak. Therefore, the configuration is weak against a malfunction such as display disorder due to static electricity. Furthermore, since the holding member is L-shaped and is also present on the side surface portion of the imaging device, the dimension in the side direction of the imaging device is increased by the thickness of the holding member.

  On the other hand, also in the prior art disclosed in the above-mentioned Patent Document 2, as in the case of Patent Document 1, since the metal member is required, the electronic device becomes heavy. However, since the metal member and the hinge mechanism are in direct contact, the configuration is more advantageous to static electricity than the prior art disclosed in Patent Document 1. However, since the hinge mechanism is fixed to the chassis member, the positional variation between the exterior member and the display unit becomes large, and the appearance quality is degraded.

  Therefore, it is an object of the present invention to provide an imaging device having a holding structure of a hinge mechanism that can achieve improvement in the anti-electrostatic characteristics, while securing the holding strength of the hinge mechanism and realizing low cost, weight reduction, and miniaturization. It is to do.
