Description

  The present technology relates to the technical field of devices. Specifically, the frame that supports the driven body is moved between the first movement position and the second movement position along a predetermined locus in accordance with the movement of the movement shaft, so that the dust adheres to the hinge mechanism with a simple structure. It relates to the technical field reduced by

  Examples of the apparatus include a recording / reproducing apparatus that records and reproduces information signals on various information recording media such as a disk-shaped recording medium and a memory card, an audio apparatus that outputs sound, and a television that displays images. Such as a display device, an information processing device such as a personal computer for processing information, a mobile terminal device represented by a mobile phone, a communication device for communicating information, an imaging device such as a video camera or a still camera, etc. There are various things.

  In such a device, for example, there is a device in which a driven body such as a lid or a display unit is rotatably supported by a hinge mechanism with respect to the main body. For example, some imaging devices such as video cameras have a display unit supported so as to be rotatable (openable and closable) with respect to a main body.

  In such a video camera, the display unit is protected at the closed position with respect to the main body to protect the display unit, and the display unit is rotated with respect to the main body and rotated (opened) to the open position. By doing so, it is possible to perform shooting and reproduction while visually recognizing images and videos displayed on the display unit.

  In a device in which the driven body is rotated with respect to the main body as described above, for example, in a video camera in which the display unit is rotated with respect to the main body, the rotation of the display unit is a pivot point of the hinge mechanism. It is connected to a dynamic shaft (open / close shaft). The hinge mechanism is covered with a cover (hinge cover), which protects the hinge mechanism and reduces dust adhesion to the hinge mechanism.

  However, if the display unit and the cover are positioned close to each other in the closed position in order to reduce the size, the display unit is rotated along an arcuate locus so that the end of the display unit on the cover side is covered. This interferes with the end of the display unit side and hinders the rotation of the display unit.

  In this case, if it is designed so that a gap is formed between the display unit and the cover at the closed position, dust enters the inside of the cover through the gap and adheres to the hinge mechanism, thereby hindering the smooth operation of the hinge mechanism. There is a fear.

  Therefore, in the conventional video camera, the movement trajectory of the display unit between the open position and the closed position is set so that the display unit does not interfere with the cover, and there is no gap between the display unit and the cover at the closed position. Or the gap is reduced (for example, see Patent Document 1).

  In the video camera described in Patent Document 1, a moving shaft (rotating shaft) that exists at a predetermined position in the closed position is moved along a predetermined route, and at this time, a display unit that is opened and closed along with the moving shaft serves as a cover. The moving trajectory is moved so as not to interfere, and the moving axis returns to the predetermined position at the open position.

[Operation of hinge mechanism]
Hereinafter, the operation of the hinge mechanism 9 when the display unit 8 is rotated between the closed position and the opened position with respect to the main body 2 will be described (see FIGS. 6, 8, 9, and 10).

  When the display unit 8 is in the closed position, the frame 12 of the hinge mechanism 9 is in the first position. First, the state of each unit when the frame 12 is in the first position will be described (see FIGS. 6 and 8). .

  When the frame 12 is in the first position, the moving shaft 11 is engaged with the first engaging portions 16 a and 16 a of the guide portions 16 and 16 formed on the base surface portion 13 of the stand 10. Accordingly, the drive cams 28, 28 through which the moving shaft 11 is inserted are on the first flat portions 27a, 27a side of the first action portions 27b, 27b of the cam guide portions 27, 27 provided on the cam bases 25, 25, respectively. The ends are pressed by pressing springs 29 and 29.

  The guides 17 and 17 are engaged with first end portions 21a and 21a of guided holes 21 and 21 formed in the frame 12, respectively.

  Further, in the state where the display unit 8 is in the closed position, as shown in FIG. 8, the rear end of the cover 7 and the front end of the display unit 8 are located in contact with or close to each other, and there is a gap between them. Does not exist, or the gap between them is very small. Therefore, the intrusion of dust into the cover 7 at the closed position is reduced.

  When the display unit 8 is rotated from the closed position to the open position with respect to the main body 2, the moving shaft 11 is guided to the guide unit 16 and the first engagement unit 16a to the second engagement unit 16b. Moved towards.

  Accordingly, the drive cam 28 is moved from the first action portion 27b of the cam guide portion 27 to the intermediate portion 27c (see FIG. 9). When the drive cam 28 is moved along the first action part 27b, the one inclined surface 31a of the annular part 31 is slid by the first action part 27b. A move is made.

  When the drive cam 28 is moved from the first acting portion 27b to the intermediate portion 27c side, the compression state of the pressing spring 29 is increased, and the pressing force of the driving cam 28 against the cam guide portion is increased.

  At this time, the guide 17 is moved relative to the guided hole 21 from the first end 21a and engaged with the second end 21b. Accordingly, the frame 12 and the display unit 8 are rotated so as to be pushed rearward and leftward (in the direction of arrow P shown in FIG. 9), and the contact of the display unit 8 with the cover 7 is avoided.

  Subsequently, when the display unit 8 is rotated toward the open position with respect to the main body 2, the moving shaft 11 is guided to the guide unit 16 and moved to the second engagement unit 16b.

  Accordingly, the drive cam 28 is moved from the intermediate portion 27c of the cam guide portion 27 to the end portion on the second plane portion 27e side of the second action portion 27d (see FIG. 10). When the drive cam 28 is moved along the second action portion 27d, the other inclined surface 31a of the annular portion 31 is slid by the second action portion 27d, so that the drive cam 27 can be smoothly moved relative to the cam guide portion 27. A move is made.

  When the drive cam 28 is moved along the second action portion 27d, the compression state of the pressing spring 29 is reduced, and the drive cam 28 is moved from the second action portion 27d toward the second plane portion 27e. A biasing force in the direction is applied.

  When a biasing force is applied to the drive cam 28 in a direction in which the drive cam 28 is moved from the second action portion 27d toward the second flat portion 27e, the movement shaft 11 and the movement shaft 11 inserted through the drive cam 28 are applied. A biasing force in the direction toward the open position is applied to the display unit 8 through the supported frame 12.

When the drive cam 28 is moved along the first action part 27b, the other inclined surface 31a of the annular part 31 is slid by the first action part 27b, so that the drive cam 27 can be smoothly moved relative to the cam guide part 27. A move is made. When the drive cam 28 is moved along the first action part 27b, the compression state of the pressing spring 29 is reduced, and the drive cam 28 is moved from the first action part 27b toward the first flat part 27a. A biasing force in the direction is applied.

  When the driving cam 28 is applied with a biasing force in the direction of moving from the first acting portion 27b toward the first flat surface portion 27a, the moving shaft 11 and the moving shaft 11 inserted through the driving cam 28 are applied. The urging force in the direction toward the closing position is applied to the display unit 8 through the supported frame 12. Therefore, even if the user releases the hand from the display unit 8 immediately before the display unit 8 is rotated to the closed position, the display unit 8 is reliably rotated to the closed position by the urging force of the pressing spring 29.

  At this time, the guide 17 is moved relative to the guided hole 21 from the second end 21b and is engaged with the first end 21a again.

  The frame 12 is moved again to the first position because the display unit 8 is rotated to the closed position.

  As described above, in the apparatus 1, when the frame 12 is moved from the first position toward the second position, the frame 12 is urged toward the second position and the frame 12 is moved to the second position. An urging mechanism 33 is provided for urging the frame 12 toward the first position when the frame 12 is moved from the second position toward the first position.

  Therefore, the frame 12 can be reliably moved to the second position and the first position, and the display unit 8 connected to the frame 12 can be reliably moved to the open position and the closed position.

  The urging mechanism 33 includes a cam base 25 having a cam guide portion 27, a drive cam 28 guided by the cam guide portion 27, and a pressing spring 26 that presses the drive cam 28 against the cam guide portion 27. ing.
