  The assembly configuration and operation of the light emitting unit of the present embodiment configured as described above will be described below.

  First, the assembly configuration will be described.

  As shown in FIG. 2A, first, a front double-sided tape 107 is attached to the front side (upper surface in the drawing) of the front case 101. At this time, the microphone ad net 107a and the microphone opening 101d are arranged so that the opening 107b of the front double-sided tape 107 and the flash opening 101a coincide, and the opening 107c and the tally opening 101c coincide. The front double-sided tape 107 is attached to a predetermined position of the front case 101 so that the two match. A microphone ad net 107a is integrally fixed to the front double-sided tape 107.

  Next, as shown in FIG. 2B, the front decorative portion 105 is attached to the front case 101 to which the front double-sided tape 107 is attached. Here, the front case 101 includes a flash opening 101a and a pair of front fitting holes 101b, and the front case 101 also includes a tally opening 101c and a microphone opening 101d. On the other hand, a flash window portion 105a, a pair of front fitting claws 105b, and a microphone hole 105g are integrally formed on the front decorative portion 105, which is a decorative member. When such a front decoration part 105 is attached to the front case 101, the front decoration part 105 is moved onto the front double-sided tape 107 so that the flash window part 105a and the flash opening part 101a substantially coincide with each other. The fitting claws 105b and the pair of front fitting holes 101b are respectively engaged or fitted. At this time, the position of the microphone ad net 107a and the position of the microphone hole 105g substantially coincide.

  Next, as shown in FIG. 2C, the tally panelite 108 made of acrylic resin, which is a light transmissive material, is inserted into the tally opening 101c on the back side of the front case 101 assembled in FIG. 2B. Here, the front side of the tally opening 101 c has a substantially circular hole, but the back side has a rectangular shape that is the same shape as the end face of the tally panel light 108. Then, the front substrate 104 is put on the back surface of the front case 101 and fixed to the front case 101 with a substrate fixing screw 109.

  As shown in FIG. 2D, the front substrate 104 is preliminarily mounted with a flash main body 102 as a light emitting member and a Fresnel lens portion 103 as a light collecting member fixed thereto, together with its light emitting circuit. A microphone unit 104a and a tally LED 104b are also mounted on the front substrate 104.

  As shown in FIG. 1, the front case 101 completed in the above assembly process is mounted and fixed on the front surface of the device main body 110, and electrical wiring is applied to electric parts such as the flash main body 102 and the microphone unit 104a. The device main body 110 is completed.

  Next, the operation will be described with reference to FIGS. 1, 4A and 4B.

  FIG. 4A is a transverse sectional view of the light emitting unit of the first embodiment, and FIG. 4B is a longitudinal sectional view, respectively. In both figures, the left side is the subject side and the right side is the device main body side.

  First, as shown in FIG. 1, the device main body 110 uses a video camera as an example in the present embodiment. When the device main body 110 is operated, the power is turned on by pressing a power button (not shown) provided on the device main body 110, and then the user-desired operations such as photographing operation and recording medium reproduction operation are performed. Perform an order. At the time of shooting, a shooting button (not shown) is pressed to shift to the shooting mode. Then, an optical signal of the subject is incident from the imaging unit 111, and a circuit such as an imaging element inside the imaging unit converts the optical signal into an electrical signal. The electric signal can be displayed as a video signal on a display means (not shown) or recorded on a recording medium (not shown).

  If there is not enough light in the shooting environment, such as when the surroundings are dark at the time of shooting, it is also possible to shoot with supplementing the amount of ambient light by flashing or video light.

  When the device main body 110 is not emitting a flash, that is, when the device main body 110 is not operated or when shooting in an environment that does not require flash light emission, when the device main body 110 is viewed from the front side, Since the vicinity of the flash body 102 of 105 is made transparent, the inside of the apparatus body 110 can be seen through the transparent window 105d of the front decoration 105. However, as shown in FIGS. 4A and 4B, there is no problem because only the Fresnel lens portion 103 can be seen in the back of the transparent window portion 105d from almost the front of the flash body 102. Further, even when viewed from the direction of arrow B1 or B2 shown in the drawing, only the Fresnel lens portion 103 or the front case 101 can be seen through the transparent window portion 105d. Further, since the translucent portion 105e is provided, the flash main body 102 and the front substrate 104 are prevented from being seen, so that the quality can be maintained.

  On the other hand, when the device main body 110 emits the flash, the light emitted from the flash main body 102 is irradiated to the outside (subject side) via the Fresnel lens portion 103 and the flash window portion 105a. More specifically, the light emitted from the Fresnel lens unit 103 is irradiated through the transparent window 105d and the semi-transparent part 105e of the flash window 105. At this time, as shown in FIG. 4A and FIG. 4B, the flash light emitted from the Fresnel lens unit 103 defines a predetermined performance and defines a light emission angle A1 or A2.

  The translucent part 105e formed around the transparent window part 105d interferes with a predetermined light emission angle A1 or A2 in the interference range C1 or interference range C2 shown in the figure, but has a translucent structure. For this reason, the surface roughness and the fine shape are set so that a predetermined amount of light can be transmitted and the performance can be secured without being completely shielded from light.

  As described above, according to the present embodiment, the flash main body 102 that is a light emitting member, the Fresnel lens portion 103 that is a light condensing member that condenses the light emitted from the flash main body 102 to approximately one side, and the light transmitting property. And a front decoration part 105 that is a decorative member that covers the flash body 102, and the front decoration part 105 is integrally formed with a translucent part that covers other than the Fresnel lens part 103. Thus, there is an excellent effect that it is possible to provide a light emitting unit that can reduce the number of parts and reduce the size of the device while suppressing the cost.

  That is, as shown in FIGS. 5A and 5B, in the prior art, it was necessary to provide the shielding member 6, and therefore the distance from the front surface of the flash body 2 to the front surface of the front decorative portion 5 must have the dimensions indicated by L3 and L4. It was. However, in the present embodiment, since the shielding member 6 is not required, the front decoration part 105 and the light emitting unit 102 can be arranged closer to each other accordingly. Specifically, as shown in FIGS. 4A and 4B, the distance from the front surface of the flash body 102 to the front surface of the front decorative portion 105 can be set to the dimensions indicated by L1 and L2. Note that L1 <L3 and L2 <L4.

  Further, by eliminating the conventionally required shielding member 6, it is possible to reduce the number of assembling steps and to eliminate the need for an adhesive or the like necessary for fixing the shielding member 6, thereby realizing a reduction in cost. .

  The semi-transparent portion 105e can be reduced in size by being formed by painting or printing.

  Further, in order to obtain the maximum shielding effect and maintain the quality while maintaining the predetermined performance in the minimum interference range C1 or C2 in FIGS. 4A and 4B, the translucent part 105e is used as the flash body of the front decoration part 105. By forming it on the surface on the 102 side, it is possible to prevent the semi-transparent portion 105e from being touched from the outside after the light emitting unit is assembled, so that deterioration of performance due to dirt or damage to the semi-transparent portion 105e is prevented. effective.

  Further, since the translucent portion 105e is formed with a satin finish (texture processing), even if the translucent portion 105e interferes with the light emission angle of the flash body 102, a predetermined amount of light is transmitted without being completely shielded from light. Ensuring sufficient performance. Furthermore, processing costs can be reduced.

  The above is the first embodiment of the present invention, but the surface roughness and fine shape of the translucent portion 105e are arbitrarily set depending on the performance to be secured and the appearance of the inside, and the first embodiment is not necessarily limited. It is not limited to the specifications.

  For example, the translucent portion 105e in the first embodiment is formed by integrally overlapping a finer satin on a rough satin for the purpose of more effective shielding effect, but is not necessarily limited to this configuration. Not what you want.

  In Embodiment 1, the semi-transparent portion 105e is used to reduce the processing cost. However, even if the semi-transparent portion 105e is configured by painting or printing, it can be shielded and reduced in size. The effect is obtained.

  Furthermore, the material of the front decoration part 105 does not necessarily need to be polycarbonate resin, if it has a light transmittance. For example, it may be acrylic resin or glass.
