Description

  The present invention relates to a video camera, and more particularly to a video camera including a light receiver of a remote controller (hereinafter simply referred to as “remote controller”).

In recent years, the demand for downsizing of mobile products has become stronger, and downsizing is also essential for video cameras. In general, the technical elements required for downsizing are downsizing of internal components and efficient component placement. Since the set surface area is reduced by downsizing, the arrangement of various operation buttons and connection terminals is also important. The configuration of a conventional video camera includes a front side including a camera lens unit and a microphone unit, a display side including a liquid crystal display unit that can be opened and closed, a drive side including a case surrounding a recording device, and a rear unit including a viewfinder and a battery mounting unit. The operation buttons and connection terminals are arranged at positions that do not interfere with the main components. For example, in the arrangement on the front side, a camera lens, a microphone, a remote control light receiver, a tally lamp for displaying that shooting is being performed, and jack terminals are arranged in order from the top and stacked in the height direction. . (For example, see Patent Document 1 and FIG. 8)
Here, the camera lens, microphone, remote control light receiving, and tally lamp must be directed to the subject side, and should be disposed on the front side in order to satisfy the functions. In addition, it is desirable to arrange the jack terminals from the front side or the drive side front side or the bottom side in order to reduce the size and ease of use. In addition, since the reduction in size in the height direction of the product has a greater visual effect than the width and length, efficient component placement on the front side is more important for downsizing the product.

  However, the video camera described above has a configuration in which the camera lens, microphone, remote control receiver, tally lamp, and jack terminals, which are front side components, are arranged in order from the top and stacked in the height direction. Therefore, the height of the product is naturally determined, and there is a problem that the height of the product cannot be reduced. Further, in order to further reduce the size of the product, it is conceivable to reduce the size of each component. However, this method has its limitations because it originally uses small components.

  In the prior art as means for solving this problem, not all the above-described front side components are stacked in the height direction, but one or more of them, for example, a remote control receiver is provided. By removing the components stacked in the height direction and placing them next to other components, the height occupied by the remote control receiver is reduced, thereby reducing the product height and size. (For example, see Non-Patent Documents 1 and 2)

  However, in the prior art described in Non-Patent Document 1, the remote control light receiver is disposed in the lateral vicinity (drive side) of the microphone unit, but is disposed at a position recessed from the arrangement surface of the microphone unit. For this reason, when trying to operate the remote control from the display side, the microphone part and the exterior housing are configured to block the remote control signal, so the remote control operation from the display side may be difficult or impossible, There was a problem that usability deteriorated.

  In the prior art described in Non-Patent Document 2, the remote control light receiver is disposed in the lateral vicinity (drive side) of the camera lens unit, and when trying to operate the remote control from the display side, the lens barrel of the camera lens unit Since the part blocks the remote control signal, the remote control operation from the display side may be difficult or impossible, and there is a problem that usability deteriorates.

  An object of the present invention is to provide a video camera that can be miniaturized while improving usability of remote control operation.

  In order to achieve the above object, in the present invention, in a video camera that records video and audio, a photoreceiver that receives irradiation light from a remote controller, a camera lens that captures video, and a microphone that collects audio. The camera lens is disposed in front of the video camera, the microphone is disposed in front of the video camera and below the camera lens, and the camera lens and microphone are disposed in front of the video camera. The light receiver is disposed on the side, and the light receiver is disposed on substantially the same surface as the microphone.

  According to the present invention, it is possible to reduce the size of the video camera while improving the usability of the remote control operation.

  Hereinafter, an embodiment of a video camera according to the present invention will be described with reference to FIGS.

  As an embodiment to which the present invention is applied, the configuration of a video camera will be described with reference to the drawings. FIG. 1 is a diagram illustrating a front side, a drive side, and a display side of a video camera. FIG. 2 is a front perspective view of the video camera. FIG. 3 is a rear perspective view of the video camera. FIG. 4 is a perspective view of the video camera when an LCD (Liquid Crystal Display) for displaying an image or the like is opened. In the following description, the height direction, the width direction, the length direction, the upper side, the lower side, the drive side, the display side, the front side, and the rear side are as shown in FIG.

  1 to 4, the video camera according to this embodiment includes a front side including a camera lens unit 1, a microphone 2, a remote control light receiver 3, a tally lamp 4, and jack terminals 5, an LCD 6, and an LCD fulcrum. It is composed of a display side composed of a part 7, a body case 8 and the like, a drive side composed of a drive part 9, a drive cover 10 and the like, and a rear side composed of an EVF (Electric View Finder) 11 and the like. Yes. The camera lens unit 1 includes a lens and a CCD (Charge Coupled Device). In this embodiment, it is assumed that the lens diameter is 37 mm and the CCD has a number of pixels exceeding 1 million pixels.

  Video and audio are captured and collected through the camera lens unit 1 and the microphone 2. The hood 12 mounted in front of the camera lens unit 1 can be attached by a screw type with the front case 13, and when changing the optical performance, the hood 12 can be removed and the conversion lens can be mounted. It is possible. In this embodiment, the lens diameter is 37 mm.

  The EVF 11 and the LCD 6 display images during shooting and playback. The LCD 6 can be opened / closed and rotated with the LCD fulcrum portion 7 as a fulcrum, and can be adjusted to an arbitrary angle suitable for the state of use. When the LCD 6 is closed, a playback operation button 14 mainly used at the time of playback is arranged on the adjacent surface, and a shooting operation button 15 mainly operated at the time of shooting is arranged on the surface that appears when the LCD 6 is opened. . Switching the power on / off and switching between the moving image mode and the still image mode are performed by operating the mode switching knob 16. Shooting is started / stopped by operating the shooting button 17. It is also possible to operate shooting start / stop with the remote control. By irradiating the remote control light receiver 3 with light instructing start / stop of shooting from the remote control, the remote control light receiver 3 detects the light and performs shooting.

  The drive unit 9 has a drive (not shown) for recording the captured video on the recording medium. When exchanging the recording medium, the drive cover 10 is rotated and opened with the lower side as a fulcrum (not shown) by operating the take-out knob 18, and the recording medium can be taken out and exchanged from the upper side. It is like that.

  Next, the arrangement of the remote control light receiver 3 will be described. The front side has a configuration in which the camera lens unit 1, the microphone 2, and the jack terminals 5 are arranged in order from the top and stacked in the height direction. Further, the remote control light receiver 3 is disposed beside the camera lens unit 1 and the microphone 2 and is disposed on substantially the same plane as the front-side microphone 2 is disposed. Since the lens barrel of the camera lens unit 1 and the microphone 2 and the front case 13 which is an exterior housing of the front part do not block the irradiation light from the remote control, the remote control light receiving performance from the display side can be improved. The usability can be improved and the product can be downsized.

  Further, the remote control light receiver 3 and the tally lamp 4 are arranged side by side in the height direction. With this arrangement, the tally lamp 4 is arranged beside the camera lens unit 1 and the microphone 2, so that further product size reduction can be achieved.

  Further, the width of the remote control light receiver 9 is made smaller than the width of the drive unit 9. Therefore, the remote control light receiver 9 does not protrude in the width direction with respect to the drive unit 9, and the aesthetic appearance of the video camera is not impaired.

  Further, the vertical position of the remote control light receiver 3 is disposed between the camera lens unit 1 and the microphone 2. With this arrangement, it is possible to prevent the camera lens unit 1 and the microphone 2 from blocking the light emitted from the remote control, thereby further improving the usability of the remote control operation.

  Further, the camera lens unit 1 is disposed on the front side, the microphone 2 is disposed below the camera lens unit 1, and the remote control light receiver 3 is disposed so as to be shifted from the camera lens unit 1 and the microphone 2 toward the drive unit 9. Even if the CCD of the unit 1 exceeds 1 million pixels and the lens diameter increases, the upper part of the camera lens unit 1 can be arranged lower than the upper part of the drive unit 9.

  Details of the configuration of the remote control light receiver 3 will be described with reference to FIG. FIG. 4 shows an exploded view of the remote control receiver. The remote control light receiver 3 includes a remote control sensor substrate 20 on which an IR filter 19 that transmits infrared rays and blocks visible light and a light receiving sensor 21 are mounted. The signal transmitted from the remote control passes through the IR filter 19 and reaches the light receiving sensor 21 on the remote control sensor substrate 20. In order to secure the light receiving angle, which is one of the remote control light receiving performances, the specification of the light receiving sensor 21 itself also affects, but the aperture size of the IR filter 19 also affects. In order to increase the left-right angle as the light receiving angle, a width in the left-right direction is required. Since the IR filter 19 according to the present invention is disposed on the drive side from the camera lens unit 1 and the microphone unit 2, if the width in the left-right direction is widened, the IR filter 19 protrudes from the drive unit and the product width is increased. In order to avoid this, the IR filter 19 is secured not only on the front surface of the IR filter 19 but also on the side surfaces thereof, so that a sufficient width in the left-right direction is secured.

  The remote control light receiver is composed of a substrate on which an IR (infrared) filter that transmits infrared rays and blocks visible light and a light receiving sensor is mounted, and the side surface or both side surfaces of the IR filter are exposed to the outside. Since the IR filter is arranged on the drive side from the camera lens unit and the microphone unit, if the width in the left-right direction is widened to satisfy the light receiving angle, it will protrude from the drive unit, increasing the product width. With this configuration, this problem can be avoided, and not only the front surface but also the side surface of the IR filter is exposed to the outside, and a sufficient width in the left-right direction can be secured.
