Description

  The present invention relates to a portable device such as a digital video camera, a digital still camera, and a mobile phone.

  FIG. 6 is a perspective view showing a configuration of a conventional video camera. A portable device such as a digital video camera includes an imaging unit 101 having a lens 100 for imaging a subject, a support unit 102 that supports the imaging unit 101, and a monitor unit for visually confirming an imaging state of the imaging unit 101. 103, and the monitor unit 103 is attached to a support unit 102 on which the imaging unit 101 is supported by a hinge 104 so that the monitor unit 103 can be opened and closed with respect to the support unit 102 and can be rotated in an open state. It is configured (for example, FIG. 6).

  In addition, the lens protector that covers and protects the lens is configured to be suspended from the support portion by a string body, and when not imaging, the lens protector is externally fitted to the lens portion to protect the lens, There is also known a digital video camera configured to remove the lens protector from the lens unit at the time of imaging.

In addition, a lens protection unit having a mirror body facing the lens is pivotally supported on a support unit that supports an imaging unit having a lens, and the lens protection unit protects the lens when the image is not captured. When taking an image of the imager himself, the lens protector is swung to a position orthogonal to the optical axis of the lens, and whether or not the imager who is the subject is within the image pickup range of the image pickup unit is visually confirmed by the mirror A portable device configured to be able to do this is also known (for example, Patent Document 1).
Japanese Patent Laid-Open No. 2002-365697

  However, in the portable device configured as shown in FIG. 6, the monitor unit and the support unit are separated and independent from each other, and the monitor unit can be opened and closed and pivoted so that the monitor unit can be opened and rotated. This requires a pivot mechanism and a flat signal line that electrically connects the monitor unit to the image pickup unit, so that the number of parts is relatively large and the structure is complicated. In addition, since a monitor unit casing is required separately from the support unit casing, there is a problem in that downsizing of the portable device is restricted, and the entire portable device becomes relatively large.

  In addition, in a video camera in which the lens protector is suspended by a string body, it is necessary to manually remove and attach the lens protector suspended by the string body. Therefore, an improvement plan was requested. Further, since the lens protector is suspended by the string body, the string body is an obstacle.

  Moreover, in the portable apparatus of patent document 1, the imaging condition when the imaging person himself / herself is imaged face-to-face can only be visually confirmed by the lens protection unit.

  The present invention has been made in view of such circumstances, and a main object of the present invention is to make the lens protection portion stop swinging at a lens open position where light reflected by the mirror body is on the optical axis of the lens. Accordingly, an object of the present invention is to provide a portable device in which a monitor unit can be fixedly arranged at a position in the same direction as a direction in which a mirror captures a subject.

  Another object is to set the lens opening position of the lens protection unit at a position where the angle formed by the mirror surface of the mirror body is 45 ° with respect to the optical axis of the lens, and the monitor unit at a position orthogonal to the optical axis of the support unit. It is an object of the present invention to provide a portable device that can eliminate the housing for the monitor unit and the flat signal line for the monitor unit by fixing the frame.

  Another object is to provide a locking means for locking the lens protection part at the lens open position, so that the lens protection part can be easily placed at the correct lens open position, and the lens protection part is placed at the lens open position. An object of the present invention is to provide a portable device that can be maintained.

  Another object of the present invention is to provide a portable device that can capture and image a subject at an arbitrary imaging angle by making the lens protection section rotatable about the optical axis of the lens.

  In addition, another object is to provide a rotating body that is rotatable about the optical axis of the lens in the support section, and by supporting the lens protection section on the rotating body, the subject can be captured at an arbitrary imaging angle. An object of the present invention is to provide a portable device capable of rotating a rotating body while holding a support portion.

  Another object of the present invention is to provide a rotating body having a ring part that is rotatably fitted to the support part, and a flange projecting radially inward from the ring part. The lens protection part is pivoted on the flange. By providing the support structure, it is an object of the present invention to provide a portable device that can operate the ring portion without being disturbed by the lens protection portion while holding the support portion.
