Description

  The present invention relates to a flash device having a remote flash function that flashes in synchronization with flash emission on the camera side.

  Conventionally, in order to photograph a subject using a plurality of lights, a remote flash device installed at a position away from the camera has been developed. The remote flash device has a light receiving unit that receives the flash emission of the master flash device connected to the camera, and emits flash in synchronization with the detection of the flash emission by the light receiving unit (see, for example, Patent Document 1). Since the remote flash device operates wirelessly, the photographer can install the remote flash device at a desired position with respect to the camera and the subject. Therefore, the amount of light applied to the subject and the direction of irradiation can be freely adjusted, and various illumination effects can be obtained.

  In general, this type of remote flash device can also be used as a master flash device by switching the photographing mode. That is, a flash device that can be used for both the master flash device and the remote flash device has been commercialized for the purpose of photographing.

The flash device flashes using the energy of the electric charge charged in the built-in capacitor. If the charging is insufficient, the desired amount of light cannot be obtained even when flashing. For this reason, the flash device has a ready light that indicates to the photographer that charging has been completed. In the conventional flash device, the ready light is attached to the back surface of the flash device in consideration of use as a master flash device. The photographer recognizes that the flash device can emit light by turning on the ready light, and presses the shutter button.

There is.

In the flash device according to the first aspect, the flash light emitting unit is attached to the apparatus main body and emits flash light to irradiate the subject with illumination light. The auxiliary light emitting unit is disposed on the front surface of the apparatus main body and emits autofocus auxiliary light. The first visual light emitting unit is disposed so as to protrude from the front surface of the apparatus main body, and irradiates light for allowing the photographer to visually confirm that charging for flashing the flash light emitting unit is completed.

  In the flash device according to the second aspect, the cover member is disposed on the front surface of the apparatus main body so as to cover the auxiliary light emitting portion and the first visual light emitting portion.

  According to another aspect of the flash device of the present invention, the pair of first visible light emitting units are respectively disposed on both side surfaces of the auxiliary light emitting unit on the front surface of the apparatus main body.

  According to another aspect of the present invention, the light receiving unit is disposed on the side surface of the apparatus main body, and the main flash emission unit causes the flash emission unit to flash in synchronization with the main flash emission emitted from the camera side that captures the subject. Is received. The first visible light emitting unit is disposed on the light receiving unit side of the apparatus main body with respect to the auxiliary light emitting unit on the front surface of the apparatus main body.

  In the flash device according to the fifth aspect, the second visual light emitting unit is disposed on the back surface of the apparatus main body in order to irradiate the photographer with the light for visually confirming that the charging is completed.

  The flash device of claim 6 has a remote mode for flashing the device main body at a position away from the camera and a master mode for flashing the device main body attached to the camera. The first visual light emitting unit is turned off during the master mode.

  According to another aspect of the flash device of the present invention, the flash light emitting unit is provided in the device main body and emits flash light to irradiate the subject with illumination light. The light receiving unit is disposed on the side surface of the apparatus main body, and receives the main flash emission so that the flash emission unit flashes in synchronization with the main flash emission emitted from the camera side that captures the subject. The first visual light emitting unit is disposed on a side surface on which the light receiving unit is disposed, and irradiates light for allowing the photographer to visually confirm that charging for flashing the flash light emitting unit is completed.

  In the flash device according to the eighth aspect, the cover member is disposed on the side surface of the apparatus main body so as to cover the light receiving portion and the first visual light emitting portion.

  In the flash device according to the ninth aspect, the first visual light emitting unit is turned off during a period in which charging is not completed, and is repeatedly turned on and off in a period from when charging is completed to when the flash light emitting unit emits flash light.

  In the flash device according to the tenth aspect, the first visual light emitting unit is turned off during the period in which the charging is not completed, and continues to be lit during the period from the completion of the charging until the flash light emitting unit emits the flash.

  In the flash device according to the eleventh aspect, the first visual light-emitting section includes a light-emitting element and a diffusion member. The light emitting element emits light having directivity. The diffusion member is disposed in front of the light emitting direction of the light emitting element, and diffuses the light irradiated from the light emitting element.

  In the flash device according to the first aspect, the first visual light-emitting portion is disposed so as to protrude from the front surface of the apparatus main body. The light emitted from the first visual light emitting part travels toward the front and side of the apparatus main body. For this reason, even when the main body of the apparatus is placed with the front or side facing the camera at a position away from the camera that shoots the subject, the photographer has completed charging to flash the flash light emitting unit. Can be easily recognized. In other words, regardless of the installation position of the flash device, the photographer can visually recognize the completion of charging of the flash device without leaving the camera.

  In the flash device according to the second aspect, the drip-proof property can be improved by covering the auxiliary light emitting unit and the first visual light emitting unit with the cover member.

It is often installed toward At this time, the side surface on which the first visual light emitting unit is arranged also faces the camera. Therefore, even when the apparatus main body is arranged with the side facing the camera at a position away from the camera that captures the subject, the photographer can easily visually recognize the completion of charging for flash emission.

  In the flash device according to the fifth aspect, since the second visual light emitting unit is disposed on the back surface of the apparatus main body, the completion of charging can be easily visually recognized from any direction by the first and second visual light emitting units.

  In the flash device according to the sixth aspect, during the master mode in which the apparatus main body is attached to the camera and flashes, the photographer can confirm the completion of charging by the light emitted from the second visual light emitting unit. For this reason, useless power consumption can be reduced by turning off the first visual light emitting unit during the master mode.

  In the flash device according to the seventh aspect, the first visible light emitting unit is disposed on the same side as the light receiving unit that receives the main flash emission from the camera side. As described above, when the flash device is installed at a position away from the camera, the light receiving unit is often installed facing the camera. At this time, the first visual light emitting unit also faces the camera. Therefore, even when the apparatus main body is arranged with the side facing the camera, the photographer can easily visually recognize the flash emission.

  In the flash device according to the eighth aspect, the drip-proof property can be improved by covering the light receiving unit and the first visual light emitting unit with the cover member. Since a common cover member can be arranged for the light receiving unit and the first visual light emitting unit, the component cost can be reduced and the apparatus can be downsized.

  In the flash device according to the ninth aspect, the first visual light emitting unit is caused to blink after the completion of charging, so that power consumption can be reduced as compared with the case where the first visual light emitting unit continues to be lit.

  In the flash device according to the tenth aspect, visibility can be improved by continuously lighting the first visual light emitting unit after completion of charging.

  In the flash device according to the eleventh aspect, it is possible to reliably irradiate light from the first visual light-emitting portion toward the front and the side. As a result, the visibility from the front and the side can be further improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 to 4 show a first embodiment of the flash device of the present invention. FIG. 1 shows the front surface (front surface) of the flash device 100. FIG. 2 shows the left side of the flash device 100 of FIG. FIG. 3 shows the right side surface of the flash device 100 of FIG. FIG. 4 shows the back surface (back surface) of the flash device 100.

The flash device 100 includes a remote mode for flashing light at a position away from the camera,
And a master mode for flashing directly attached to the camera. That is, the flash device 100 functions not only as a master flash device directly connected to the camera, but also as a remote flash device installed at a position away from the camera, depending on the mode setting.

  In FIG. 1, the flash device 100 has a flash body 12 that is attached to the main body 10 and an upper portion U of the main body 10 so as to be rotatable in the left-right direction and the vertical direction in FIG. The apparatus main body 10 includes a pair of auxiliary light emitting units 14 that irradiate focus auxiliary light on the flash light emitting unit 12 side of the front surface F, and a pair of ready lights 16 (first visual recognition) on both the left and right sides of the auxiliary light emitting unit 14. Light emitting part). The focus auxiliary light is emitted when the camera focuses the subject.

  Each auxiliary light emitting unit 14 includes an LED and a lens attached to the front surface of the LED. For example, a horizontal stripe irradiation pattern is formed on the lens of the left auxiliary light emitting unit 14 in FIG. 1, and a vertical stripe irradiation pattern is formed on the lens of the right auxiliary light emitting unit 14. Then, the subject is focused by the horizontal stripe pattern and the vertical stripe pattern irradiated to the subject or the like when the auxiliary light emitting unit 14 emits light. Since the LED of the auxiliary light emitting unit 14 irradiates a pattern on a subject or the like, the light emission amount and the power consumption are larger than those of the ready lights 16 and 32 described later.

  The ready light 16 is attached to a position close to the left side surface L and the right side surface R of the apparatus main body 10, and the photographer has confirmed that charging of a capacitor (not shown) has been completed in order to flash the flash light emitting unit 12. Irradiate light to make it visible. Specifically, the ready light 16 is turned off during a period when charging is not completed, and is repeatedly turned on and off during a period from when charging is completed until the flash light emitting unit 12 emits flash light. The ready light 16 is always turned off when the flash device 100 is set to the master mode. During the master mode in which the apparatus main body 10 is attached to the camera and flashes, the photographer can confirm the completion of charging with the ready light 32 (see FIG. 4) attached to the back B of the apparatus main body 10. For this reason, useless power consumption can be reduced by turning off the ready light 16 during the master mode.

  As shown in FIGS. 2 and 3, each ready light 16 includes an LED 16 a (light emitting element) and a diffusion member 16 b attached to the front surface of the LED 16 a in the light irradiation direction. The LED 16a has directivity for irradiating light toward the front F. The diffusion member 16b has a substantially hemispherical shape, and is disposed so as to protrude from the front surface F (excluding a cover member 18 described later) of the apparatus main body 10. The diffusing member 16b diffuses light with high directivity emitted from the LED 16a to the front F, the left side L, and the right side R. That is, the light from the ready light 16 is irradiated radially toward the direction excluding the back surface B side of the apparatus main body 10. For this reason, the visibility from the front F, the left side L, and the right side R of the ready light 16 can be improved.

  A cover member 18 is bonded to the front surface F of the apparatus body 10 so as to cover the auxiliary light emitting unit 14 and the ready light 16. The cover member 18 is formed of a red transparent resin. As shown in FIGS. 2 and 3, the cover member 18 has a substantially U-shaped cross section. For this reason, the light diffused toward the left side L and the right side R by the diffusion member 16 b is transmitted through the cover member 18 and travels radially from the apparatus main body 10. By making the cover member 18 common to the auxiliary light emitting section 14 and the ready light 16, the component cost can be reduced. In addition, since it is not necessary to add a cover member dedicated to the ready light 16, it is possible to minimize the adhesion portion of the apparatus main body and prevent the drip-proof property from being lowered. In FIG. 1, the left side of the cover member 18 is cut out for easy understanding.

As shown in FIG. 2, a light receiving unit 20 (photosensor) is formed on the left side surface L of the apparatus body 10. The light receiving unit 20 receives flash emission of a master flash device connected to a camera (not shown) during the remote mode. A cover member 22 is bonded to the left side surface L of the apparatus main body 10 so as to cover the light receiving unit 20. The cover member 22 is formed of a red transparent resin.

  A battery cover 24 for inserting and removing the battery is detachably attached to the left side surface L of the apparatus main body 10. The battery is exchanged by releasing the lock by removing the battery lid 24 from the apparatus body 10 by sliding the battery lid 24 toward the lower part D of the apparatus body 10. Further, the lower part D of the apparatus main body 10 has an attachment leg 26 and a lock lever 28 for attaching the apparatus main body 10 to a dedicated stand, a tripod attachment adapter, or an accessory shoe of a camera.

  As shown in FIG. 2, a push button PUSH is formed on the left side surface L of the flash light emitting unit 12. While the push button PUSH is being pressed, the flash light emitting unit 12 can be rotated in the left-right direction and the up-down direction with respect to the apparatus main body 10. That is, the flash device 100 has a left / right bounce function and an up / down bounce function.

  As shown in FIG. 4, the back surface B of the apparatus body 10 includes a liquid crystal display unit 30, a ready light 32 (second visual light emitting unit), a flash button 34, a power key 36, and a cross key 38. Further, a scale indicating the bounce angle in the vertical direction is engraved on the back surface of the flash light emitting unit 12.

  The liquid crystal display unit 30 displays a setting screen and the like when setting the shooting mode. The ready light 32 (second visual light emitting unit) emits light to make the photographer visually recognize that charging of a capacitor (not shown) has been completed in order to cause the flash light emitting unit 12 to flash light. Specifically, the ready light 32 is turned off during a period in which charging is not completed, and is continuously turned on in a period from when charging is completed until the flash light emitting unit 12 flashes.

  The flash button 34 functions as a test light emission button. When the flash button 34 is pressed, the flash light emitting unit 12 flashes using the charge charged in the capacitor at that time. The power key 36 is pressed when the power is turned on while the flash device 100 is turned off, and is pressed when the power is turned off while the flash device 100 is turned on.

  The cross key 38 has both a function for selecting setting items displayed on the liquid crystal display unit 30 and a function for directly controlling the state of the flash device 100. For example, the four keys of the cross key 38 simultaneously press the zoom key “ZOOM” and the minus key “−”, and after the setting screen is displayed on the liquid crystal display unit 30 (in the setting mode), the zoom key “ZOOM” is again displayed. The key functions as an up / down / left / right key for selecting a setting item until the minus key “−” is pressed simultaneously. In addition to the setting mode, the zoom key “ZOOM” of the cross key 38 functions as a key for adjusting the irradiation angle of the light emitted from the flash light emitting unit 12, and the plus key “+” and the minus key of the cross key 38. “−” Functions as a key for adjusting the light emission amount of the flash light emitting unit 12, and the mode key “MODE” of the cross key 38 functions as a key for selecting a dimming mode.

FIG. 5 and FIG. 6 show an example of wireless multiple flash photography using the flash device of the first embodiment. In this example, the flash device 100 is installed on the left side of the subject when viewed from the camera 200. The flash device 100 is set to the remote mode, and functions as a remote flash device. A master flash device 300 is directly attached to the camera 200. Usually, the photographer stands on the back side of the camera 200 and photographs the subject. At this time, the photographer cannot visually recognize the ready light 32 on the back surface B of the flash device 100 but can easily visually recognize the ready light 16 on the left side surface L side of the flash device 100. The photographer recognizes the completion of charging of the flash device 100 by blinking the ready light 16, and then presses the shutter button of the camera 200. The master flash device 300 flashes in synchronization with the pressing of the shutter button. In the flash device 100, the light receiving unit 20 detects the flash emission of the master flash device 300, and flashes in synchronization with this detection. That is, wireless multiple-flash photography is performed.

  FIG. 7 shows another example of wireless multiple-flash photography using the flash device of the first embodiment. In this example, the flash device 100 is installed on the left rear side of the subject when viewed from the camera 200. As described above, when photographing with the flash device 100 in the backlight state, the photographer cannot visually recognize the ready light 32 on the back surface B of the apparatus main body 10. However, the completion of charging can be easily visually recognized by the two ready lights 16 on the front surface F of the apparatus main body 10. When it is difficult for the light receiving unit 20 to detect the flash emission of the master flash device 300, the light receiving unit 20 can be opposed to the camera 200 by turning only the device body 10 counterclockwise in the figure. At this time, similarly to FIG. 6, the photographer can visually recognize at least the ready light 16 on the left side L side of the flash device 100.

  FIGS. 8 and 9 show another example of wireless multiple flash photography using the flash device of the first embodiment. In this example, the flash device 100 is installed on the right rear side of the subject when viewed from the camera 200. The apparatus main body 10 is installed with the front surface F facing the right side of the drawing in order to point the light receiving unit 20 toward the camera 200. The flash light emitting unit 12 directs the light irradiation direction (arrow in the figure) to the subject. In this case, the photographer visually recognizes the completion of charging with the ready light 32 on the back surface B of the apparatus main body 10 instead of the ready light 16 on the front surface F of the apparatus main body 10 and shoots the subject. When the ready light 32 is poorly visible, as shown in FIG. 9, the photographer can rotate the device main body 10 only in the clockwise direction in the drawing so that the photographer can embed the ready light 32 embedded in the back surface B of the device main body 10. Instead, the ready light 16 protruding from the front surface F of the apparatus main body 10 can be visually recognized. That is, the visibility of the ready light is greatly improved by slightly adjusting the orientation of the apparatus body 10 with respect to the camera 200.

  FIGS. 10 and 11 show another example of wireless multiple flash photography using the flash device of the first embodiment. In this example, the flash device 100 is installed on the right side of the subject when viewed from the camera 200. The apparatus main body 10 is rotated so that the light receiving unit 20 faces the camera 200, and the ready light 16 faces in the direction opposite to the light irradiation direction of the flash light emitting unit 12. In this case, the photographer visually recognizes the completion of charging with the ready light 32 on the back surface B of the apparatus main body 10 and photographs the subject.

  When the ready light 32 is poorly visible, as in FIG. 9 described above, by rotating only the apparatus main body 10 in the clockwise direction in the drawing, the photographer can use the ready light 32 embedded in the back surface B of the apparatus main body 10. The ready light 16 protruding from the front surface F of the apparatus main body 10 is visible. Further, when the light receiving unit 20 can detect the flash emission of the master flash device 300 attached to the camera 200 by reflection from the wall surface behind the subject, as shown in FIG. You may aim. In this case, the photographer can visually recognize the ready light 16 protruding from the front surface F of the apparatus main body 10.

  FIG. 12 shows another example of wireless multiple-flash photography using the flash device of the first embodiment. In this example, the flash device 100 is installed in front of the subject as viewed from the camera 200. The apparatus main body 10 is rotated so that the light receiving unit 20 faces the camera 200, and the ready light 16 faces in the direction opposite to the light irradiation direction of the flash light emitting unit 12. In this case, the photographer can visually recognize the completion of charging with the ready light 16 on the front surface F of the apparatus main body 10.

As described above, in the present embodiment, by attaching the ready light 16 protruding to the front surface F to the apparatus main body 10, the apparatus main body 10 places the front F or the side surfaces L and R on the camera at a position away from the camera that captures the subject. Even in the case where the camera is disposed, the photographer can easily visually recognize that the charging for flashing the flash light emitting unit 12 is completed. In particular, by arranging the pair of ready lights 16 on both the left and right sides of the front surface F of the apparatus main body 10, the completion of charging can be reliably recognized from either the left side L or the right side R of the apparatus main body 10. Furthermore, the photographer can also visually recognize the completion of charging by the ready light 32 arranged on the back surface B of the apparatus main body 10. As a result, regardless of the installation position of the flash device 100, the photographer can visually recognize the completion of charging of the flash device 100 without leaving the camera.

  The cover member 18 can improve the drip-proof property of the auxiliary light emitting unit 14 and the ready light 16. Since the cover member 18 can be shared by the auxiliary light emitting unit 14 and the ready light 16, the component cost can be reduced, and the flash device 100 can be downsized.

  By making the ready light 16 blink after completion of charging, the power consumption can be reduced compared to the case where the ready light 16 continues to be lit. By turning off the ready light 16 during the master mode, wasteful power consumption can be reduced.

  FIG. 13 shows a second embodiment of the flash device of the present invention. The same elements as those described in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted. In this embodiment, an apparatus main body 10A is formed instead of the apparatus main body 10 of the first embodiment. The apparatus main body 10 </ b> A has one ready light 16 in the cover member 18. The ready light 16 is disposed on the light receiving unit 20 side with respect to the auxiliary light emitting unit 14. Other configurations are the same as those of the first embodiment.

  When the apparatus main body 10A is arranged at a position away from the camera, the light receiving unit 20 is often arranged facing the camera side in order to reliably flash the flash light emitting unit 12 in synchronization with the main flash light emission. At this time, the left side surface L on which the ready light 16 is arranged also faces the camera. The photographer can visually recognize the flashing of the ready light 16 protruding from the front surface F from the left side surface L side. Therefore, even when the apparatus main body 10A is arranged with the side face L facing the camera at a position away from the camera that captures the subject, the photographer can easily visually recognize the completion of charging for flash emission.

  As described above, also in this embodiment, the same effect as in the first embodiment can be obtained.

  14 and 15 show a third embodiment of the flash device of the present invention. The same elements as those described in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted. In this embodiment, an apparatus main body 10B is formed instead of the apparatus main body 10 of the first embodiment. The apparatus main body 10 </ b> B has one ready light 17 at a position close to the light receiving unit 20. A ready light is not arranged in the cover member 18 that covers the auxiliary light emitting unit 14. Other configurations are the same as those of the first embodiment except for the structure of the left side surface L.

  The ready light 17 is attached to a position protruding from the left side surface L of the apparatus main body 10B, so that the photographer can visually recognize that charging of a capacitor (not shown) has been completed in order to flash the flash light emitting unit 12. Irradiate light. Specifically, the ready light 17 is turned off during a period when charging is not completed, and is repeatedly turned on and off during a period from when charging is completed until the flash light emitting unit 12 emits flash light. Similar to the ready light 16 of the first embodiment, the ready light 17 includes an LED (light emitting element) and a diffusing member attached to the front surface of the LED in the light irradiation direction. The same parts as those in the first embodiment are used for the LED and the diffusing member. That is, the diffusing member diffuses the light having a high directivity emitted from the LED to the left side L, the front F, and the rear B.

A cover member 23 is bonded to the side surface L of the apparatus main body 10B so as to cover the ready light 17 and the light receiving unit 20. The cover member 23 has a substantially U-shaped cross section so as to cover the ready light 17 protruding from the side surface L. The material of the cover member 23 is the same as that of the cover member 22 of the first embodiment. For this reason, the light diffused by the diffusing member 16b passes through the cover member 23 and travels radially toward the left side L, the front F, and the rear B of the apparatus main body 10B.

  When the apparatus main body 10A is arranged at a position away from the camera, the light receiving unit 20 is often arranged facing the camera side in order to reliably flash the flash light emitting unit 12 in synchronization with the main flash light emission. At this time, the left side surface L on which the ready light 17 is arranged also faces the camera. For this reason, by arranging the ready light 17 on the same surface as the light receiving unit 20, when the apparatus main body 10B is disposed with the side face L facing the camera at a position away from the camera that captures the subject, The completion of charging for flash emission can be easily recognized.

  Since the flash light emitting unit 12 can be rotated in the left-right direction with respect to the apparatus main body 10B, the flash light emitting unit 12 can be directed to an arbitrary position with the light receiving unit 20 and the ready light 17 facing the camera side. In other words, the light emission of the ready light 17 can always be recognized and the light receiving unit 20 can receive the master flash emission from the camera side in a state where the camera and the flash device are arranged at arbitrary positions with respect to the subject. .

  As described above, also in this embodiment, the same effect as in the first embodiment can be obtained.

  In the above-described embodiment, an example has been described in which the ready light 16 (or 17) is repeatedly turned on and off during the period from when the charging is completed to when the flash light emitting unit 12 flashes. The present invention is not limited to such an embodiment. For example, the ready light 16 or 17 may continue to be lit during a period from when the charging is completed until the flash light emitting unit 12 flashes. In this case, the visibility of the ready lights 16, 17 can be improved.

  In the first and second embodiments described above, the example in which the cover member 18 is shaped to cover a part of the front surface F of the apparatus main bodies 10 and 10A has been described. The present invention is not limited to such an embodiment. For example, the cover member may have a shape that covers a part of the side surfaces L and R from the front surface F of the apparatus main body 10A. In this case, the visibility from the side surfaces L and R of the ready light 16 can be further improved.

  In the above-described embodiment, an example in which the ready light 16 (or 17) is configured by an LED that emits light having directivity and a diffusion member that is disposed in front of the light irradiation direction of the LED has been described. The present invention is not limited to such an embodiment. For example, the ready light may be formed using only an LED that does not have directivity in the light irradiation direction, and the LED may be attached so as to protrude from the apparatus main body.

  In the above-described embodiment, an example in which the present invention is applied to a flash device having a light receiving unit that receives master flash light emission and used for wireless multiple flash photography has been described. The present invention is not limited to such an embodiment. For example, the present invention may be applied to a flash device having a connector that receives a master flash emission synchronization signal via a signal line.
