Description

  The present invention relates to an opening / closing device and a portable electronic device suitable for, for example, a mobile phone terminal and a PDA (Personal Digital Assistant).

  Conventionally, various portable electronic devices, for example, prevent damage or destruction of the display, prevention of damage or destruction of the camera lens, prevention of adhesion of fingerprints, dust or dust, prevention of key misoperation, external connection, etc. In many cases, a cover mechanism is provided to protect a portion that performs an important function in the device, such as prevention of dust and dust from entering the terminal. In particular, in the case of a camera lens, scratches, fingerprints, dust, dust, and the like have a large effect on a captured image, so it is considered effective to provide the cover mechanism. In addition, the cover mechanism is also effective in the case of a portable electronic device such as a mobile phone terminal that is always carried around by a user and is expected to be used in a hard manner such as when it hits another object in a pocket or bag. It is thought that there is.

  Here, as a conventional cover mechanism used for a portable electronic device, Japanese Patent Laid-Open No. 6-273638 discloses a state in which a camera lens is protected by rotating a barrier of the camera lens. And a barrier device capable of taking a state in which the camera lens is exposed is disclosed. In addition, the barrier device is provided with a gear and a sector gear around the rotation axis of the barrier, and the sector gear is configured to be connectable to a lens barrel feeding and retracting mechanism gear as necessary. . That is, in this barrier device, for example, when the barrier is rotated by a user, the feeding and retracting mechanism gear is driven via the gear and the sector gear around the rotation axis of the barrier. The lens barrel is extended or retracted. The barrier device also includes a click mechanism or a lock mechanism for stopping the barrier at a predetermined position when the barrier is rotated. Although the details of the click mechanism or the lock mechanism are not shown in this published patent publication, in the case of the barrier device, as described above, a large number of components such as gears and sector gears are mounted around the rotation axis of the barrier. Therefore, it is considered that each part for realizing the click mechanism or the lock mechanism is separately installed in a place where the operation of the gear or sector gear is not hindered, for example, on the exterior of the housing. .

Since the first protrusion 31, the second protrusion 32, the arc 34, and the like are formed integrally with the cylindrical portion 39, there is no need to prepare them as separate parts. Therefore, according to the mobile phone terminal of the present embodiment, an increase in the number of parts when the cover mechanism is mounted can be suppressed, and an increase in size, weight, and price can be effectively suppressed.

  Further, according to the cover mechanism of the present embodiment, the cover interlocking member 10 is connected to the rotating shaft portion 14 of the cover member 2, and the first stopper portion 24, the second stopper portion 25, the holder Since the portion 26 is concentrated around the cover interlocking member 10 (that is, around the rotation shaft portion 14 of the cover member 2), space efficiency is good. That is, according to the mobile phone terminal of the present embodiment, the arrangement of components in consideration of space efficiency is realized, so that the size can be reduced.

  In addition, in the cover mechanism of this embodiment, the opening and closing of the cover mechanism can be detected by the magnet 11 provided on the cover interlocking member 10 and the MR sensor provided on the circuit board, for example. The opening / closing detection of the cover mechanism can be used for operation control of a function related to the covered member protected by the cover mechanism. That is, for example, when the cover member is the lens 3 of the camera module as in the present embodiment, the control unit 71 activates the camera function of the camera module when detecting that the cover mechanism is in the open state. Conversely, control can be performed to stop the camera function when it is detected that the cover mechanism is closed.

  The above description of the embodiment is an example of the present invention. For this reason, the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made according to the design or the like as long as the technical idea according to the present invention is not deviated.

  For example, the cover mechanism according to the present invention is not limited to a mobile phone terminal, and can be applied to various portable electronic devices such as PDAs, portable audio devices, digital cameras, and the cover mechanism of the present invention is described above. In addition to the lens 3 and the light 5, various members to be covered such as a mirror for self-taking, a key, a display unit, and an external connection terminal may be protected. Of course, the cover mechanism according to the present invention can be applied not only to the purpose of protecting the covered member but also to an opening / closing mechanism of an insertion port of an external memory or a disk medium.

  Moreover, in the cover mechanism of this embodiment, if the arrangement position of the 1st stop part 24 and the 2nd stop part 25 is changed, or the magnitude | size and installation position of the rectangular part 33 of the cover interlocking member 10 are changed. The opening / closing angle and opening / closing amount of the cover member 2 can be set to different opening / closing angles and opening / closing amounts from the example of FIG.
