  In recent years, due to diversification of needs, video cameras having different specifications among one model have been demanded. For example, the cover cover color, the zoom magnification of the photographic lens, the presence or absence of a lighting device, the type of jack for interface with the outside, and so on. In imaging devices such as video cameras, the multi-focal / optical variable magnification optical system is the mainstream of the above-described photographing optical system such as a mobile phone, and the illumination system light with respect to the optical axis of the photographing optical system. An axis that is relatively distant from each other and it is necessary to match the illumination range with the photographing optical system, and it is desirable to be able to select an illumination device that can be set according to the photographing optical system. Corresponding to these differences in specifications, setting camera parts individually, configuring them with an adjustment mechanism, etc., or installing non-functional parts leads to an increase in product cost and even unnecessary functions.

  7 and 8, reference numeral 43 denotes a light shielding holder corresponding to the shape of the first light emitting diode 57. The illumination lens 41 is restricted to the first position in the optical axis direction by bringing the surface 41A into contact with the surface 11A of the exterior cover 11 and the surface 41B into contact with the surface 11B. Further, the illumination lens 41 is held at the first position in the optical axis direction by contacting the surface 41C with the surface 43C of the light shielding holder 43 and the surface 41D with the surface 43D. The first position in the optical axis direction is set with an optically calculated distance from the light emitting surface of the light emitting diode 57 as a light source.

  The light shielding holder 43 is set so that the illumination lens 41 according to the first embodiment of the present invention is incorporated in a posture in which the first position in the optical axis direction and the protruding portion facing direction are substantially vertical. The light leakage space between the light emitting diode 57 and the electric circuit board 55 is set to a minimum to improve light leakage in directions other than the light distribution direction.

For example, if the mounting land pattern of the electric circuit board 55 is set so that the first light emitting diode and the second light emitting diode can be mounted, the subject illumination lamp in the third embodiment and the fourth embodiment is configured. The different parts are the light-emitting diode and the light-shielding holder of the light source. The mounting of the light-emitting diode 57 of the third embodiment and the light-emitting diode 58 of the fourth embodiment is exchanged, and the light-shielding holder 43 and the light-shielding holder 45 corresponding to each are replaced. The subject illumination lamp can be selectively set in terms of cost, performance, etc., simply by exchanging and changing the mounting posture of the illumination lens 41.

  As shown in FIGS. 4A, 6A, 8A, and 10A, the light emitting portion center 57E of the first light emitting diode 57 and the light emitting portion of the second light emitting diode 58 are provided. The centers 58E do not coincide with the optical axis 41E of the illumination lens 41, respectively. When the optical axis of the illumination lens 41 cannot be configured to coincide with the optical axis of the photographing optical system 20, the light distribution center of the light from the light source by the subject illumination lamp 40 is kept at a constant distance from the optical axis of the photographing optical system 20. For the purpose of intersecting, the luminance center of the light source is intentionally shifted from the optical axis of the illumination lens 41. The shift amount can be arbitrarily set depending on the distance between the optical axis of the photographing optical system 20 and the optical axis of the illumination lens 41, the luminance of the subject illumination lamp 40, and the purpose of use of the camera. In the third embodiment, the shooting distance is set to about 150 cm with respect to the zoom magnification of 20 times of the photographing optical system, and in the third and fourth embodiments, the zoom magnification of the shooting optical system is set to correspond to about 75 cm. is doing. Of course, the light emitting part center 57E of the first light emitting diode 57 and the light emitting part center 58E of the second light emitting diode 58 may be configured to coincide with the optical axis 41E of the illumination lens 41 for the purpose of photographing effect. good. Such an arrangement can also be used for the light emitting unit 30 of the strobe device.

  In FIGS. 11 and 12, reference numeral 60 denotes a sheet metal for grounding with an electric circuit board or a housing sheet metal, and uses spring phosphor bronze having a thickness of about 0.2 mm in consideration of electric characteristics and thermal conductivity. ing.

  The sheet metal 60 has electrical connection portions 60A, 60B, and 60C with the circuit board 55, and the connection portion 60D is electrically connected to the housing sheet metal. The connection portion 60A is in contact with the GND pattern of the substrate 55, and is brought into pressure contact with the GND pattern of the substrate 55 by the spring property of the sheet metal 60, and in contact with the connection portion 60A on the GND pattern for the purpose of improving adhesion. The area is finely grained with solder. A GND pattern is also provided on the opposite side of the GND pattern substrate surface, and is electrically connected by means such as through-hole plating, covering the projection range of the light emitting diode 57 and surrounding the periphery of the mounting pattern of the light emitting diode. It has been. Further, a USB jack 51 and a DV jack 52 having a metal shield frame are arranged near the side, and the shield frame is soldered to the GND pattern of the substrate 55 and mounted on the substrate 55. For example, when the light emitting diode 57 is selected and used with a high luminance, there is a problem that the luminance of the light emitting diode itself is reduced due to heat generation of the light emitting diode. Can be efficiently radiated to the outside of the camera body.

  To explain the heat dissipation path, heat from the light emitting diode is transmitted to the GND pattern that covers the projection range of the light emitting diode 57 and surrounds the mounting pattern of the light emitting diode, and the GND pattern is provided in the vicinity. Since it is connected to the metal shield frame of the USB jack 51 and the DV jack 52, the heat generated by the light emitting diode is radiated to the outside of the camera through a metal shield frame partially exposed outside the camera body. In order to increase the heat radiation efficiency, a hole in consideration of the appearance design may be formed in the jack cover 50, or a gap may be formed in a place that is not conspicuous on the appearance.

  Further, the heat from the light emitting diode is transmitted to the GND pattern provided so as to cover the projection range of the light emitting diode 57 and surrounding the mounting pattern of the light emitting diode, and the heat is transmitted to the GND pattern on the opposite surface through the through hole. It is transmitted to the sheet metal 60 and is radiated to the outside from the radiation fin portion 60F of the sheet metal 60.

  Furthermore, since the contact portion 60E of the sheet metal 60 is in contact with the contact portion 13E of the plastic-plated microphone cover 13 described later, heat is also radiated from the microphone cover 13 exposed outside the camera body.

  13 and 14, reference numeral 13 denotes a microphone cover that constitutes a part of the exterior cover, which has a sound insertion hole for the microphone, is molded from a resin material, and is plastic-plated on the entire surface. 70 is a microphone, 71 is a damper rubber for isolating the microphone from external vibration, 72 is a metal having a lid function for closing the microphone 70 held by the damper rubber 71 in the box portion 13B of the microphone cover 13 The microphone plate is made of a resin containing metal and has a function of shielding the microphone portion from external noise such as electromagnetic waves. 73 is a fine sheet composed of a multi-hole material, and 74 is a shield sheet metal conventionally used for the microphone part (FIG. 11).

  The microphone part has become very delicate with recent improvements in microphone element sensitivity, and the influence of electromagnetic waves etc. can no longer be ignored. Materials such as metal plates were used. Alternatively, when the cover having the sound insertion hole is made of resin or the like, it is necessary to wrap the microphone 70 with a shield metal plate 74 or the like as shown by a two-dot chain line in FIG.

  Further, when the cover having the sound insertion hole is made of resin or the like, the area of the end surface of the sound insertion hole is increased in consideration of the strength and flowability of molding. Since the influence of wind noise increases when the area of the end surface of the sound insertion hole is large, a fine sheet 73 as shown by a two-dot chain line in FIG. 11 is inserted between the microphone and the wall having the sound insertion hole. As shown in FIG. 14, since the microphone is moved away from the wall having the sound hole and parts and space are required for this purpose, it is difficult to reduce the number of parts and reduce the size. Even if it is composed of a metal plate, the number of parts is not reduced simply by replacing the plate parts and the fine sheet 73.

  However, the microphone cover 13 is formed by forming a conductive film such as plastic plating on the entire surface of the microphone cover 13 made of a material such as a resin, and connecting the conductive film to the GND of the electric circuit board or the housing sheet metal. Thus, the shield plate 74 that has been conventionally required is reduced. Further, since the plating is performed on the entire surface, the plating layer has a structure in which the resin is sandwiched, and the wall thickness having the microphone sound insertion hole can be reduced, and the plating layer is thicker than the other surface at the edge portion 13A around the hole. Due to the nature of sticking, the R at the edge portion of the sound insertion hole is increased, and there is an effect of reducing wind noise. This eliminates the need to insert the fine sheet 73 between the microphone and the wall having the sound insertion hole, making it possible to bring the microphone closer to the wall having the sound insertion hole, thereby reducing the number of parts and reducing the size. It becomes possible.
