Description

  The present invention relates to an illumination mechanism of an operation panel that illuminates an operation panel provided with switches for various settings and adjustments of an imaging apparatus, and particularly recognizes the operation panel when an operator operates the switches. The present invention relates to an illumination mechanism that is easy to illuminate so that unnecessary light is not diffused around.

  In studio photography and night photography, there are many cases where the surroundings are dark or it is necessary to cut off unnecessary light depending on the shooting environment. At this time, the operation of the switches provided on the operation panel of the imaging device is dark. Tick marks, characters, switch names, etc. are sometimes difficult to see and sometimes misoperates.

  Therefore, conventionally, in order to make the scales and characters easy to see, the operation panel is made of a resin such as translucent acrylic, and printed or shaded in black on the area other than the memory and characters. A method of irradiating the scale and letters by irradiating from the whole, and a method of illuminating the operation panel by installing a plurality of light sources such as light emitting diodes so as to surround the operation panel beside the operation panel have been considered. It was.

  Further, as in Patent Document 1, a light-emitting diode that is a light source protrudes from the operation panel front surface on the upper front surface of the operation panel and is installed substantially vertically, and is irradiated in a substantially vertical direction on the operation panel. A television camera is disclosed in which the reflected light is reflected toward the operation panel below by a reflecting material to illuminate the entire operation panel.

JP 2008-96808 A

However, the method of irradiating the entire panel from the back side of the operation panel can be recognized because characters and memory shine brightly, but has a drawback that it is difficult to recognize because the switch itself does not shine.
Further, in the case of installing a light source such as a light emitting diode so as to surround the operation panel on the side of the operation panel, a plurality of light sources are required to irradiate the entire panel, resulting in an increase in manufacturing cost and power consumption of the imaging apparatus. was there.

  The television camera disclosed in Patent Document 1 can minimize the number of light-emitting diodes that serve as light sources. However, since the light-emitting diodes are installed so as to protrude from the operation panel, not only the operation panel is illuminated but also the surroundings. Light diffuses into the surface.

In studio photography, a subject is photographed from multiple directions with multiple imaging devices, but a lamp called a tally is turned on so that performers and staff can recognize which imaging device is currently capturing. Yes.
In the case of studio photography as described above, in the operation panel of Patent Document 1, since light diffuses around, the leaked light may be mistaken for tally, which is very inconvenient.

  Further, since the light emitting diode of the television camera of Patent Document 1 is installed so as to protrude from the operation panel, the light beam may directly enter the operator's eyes. There was also the possibility of hurting.

  The present invention has been made in view of the above problems, and not only illuminates the operation panel efficiently with a minimal light source but also illuminates the operation panel of the image pickup apparatus so as not to diffuse unnecessary light to the surroundings. The purpose is to provide.

The present invention has been made to solve the above-described problems, and the invention according to claim 1 is provided in the operation panel in an operation panel illumination mechanism that illuminates the operation panel provided in the imaging apparatus. In addition, a plurality of light introducing portions for introducing light from a light source provided on the back side of the operation panel to the front side, and an operation panel peripheral wall attached to the operation panel so as to surround the vicinity of the outer peripheral edge of the operation panel The operation panel peripheral wall covers the light introduction part at a position corresponding to the light introduction part provided on the operation panel, and transmits the light introduced from the light introduction part to the operation panel. A light guide portion that guides the front surface in a direction to illuminate is formed, and on the wall side of the predetermined range of the peripheral wall of the operation panel, the light guide portions are independently provided at positions corresponding to the plurality of light introduction portions. Part is shape A plurality of light sources that illuminate a predetermined range of the front surface of the operation panel as a spot light and that face the range where the light guide portion is independently formed on the peripheral wall of the operation panel. The operation is characterized in that the light guide unit communicated with the light introduction unit is formed to illuminate the introduced light so that the entire operation panel is lowered with respect to the illuminance of the spot light. It is a panel illumination mechanism.

  According to a second aspect of the present invention, in the operation panel illumination mechanism according to the first aspect, the light introducing portion has a slit shape, and light from the light source is introduced from the slit shape portion. It is characterized by.

  According to a third aspect of the present invention, in the operation panel illumination mechanism according to the first or second aspect, the light introducing portion is provided at least at an upper portion of the operation panel.

  Further, the invention according to claim 4 is the operation panel illumination mechanism according to any one of claims 1 to 3, wherein the side cross-sectional shape of the light guide portion is a bowl shape, and thus from the light source. The light can be guided in the direction of illuminating the front surface of the operation panel.

  According to a fifth aspect of the present invention, in the operation panel illumination mechanism according to any one of the first to third aspects, the light guide portion is a reflective surface having a predetermined angle with respect to the normal of the operation panel. The light reflected by the reflecting surface is guided in a direction to illuminate the front surface of the operation panel.

  Further, the invention according to claim 6 is the operation panel illumination mechanism according to any one of claims 1 to 5, wherein a member having translucency is provided in the vicinity of the light guide outlet in the light guide portion. It is characterized by being fitted.

According to the operation panel illumination mechanism of the present invention, the light of the light source can be efficiently illuminated in the direction of the front surface of the operation panel, so that the number of light sources can be greatly reduced, the manufacturing cost can be reduced, and the imaging device can be consumed. Electric power can be reduced. Further, since the entire operation panel is illuminated, not only characters and scales but also switches and volumes can be recognized accurately, so that operation errors can be greatly reduced. In addition, on the wall side of the predetermined range of the peripheral wall of the operation panel, a light guide unit is independently formed at a position corresponding to the plurality of light introducing units, and spot light is applied to each predetermined range of the front surface of the operation panel. On the wall side that illuminates and faces the range where the light guide part is independently formed on the operation panel peripheral wall, the light introduced by the light guide part communicating with the plurality of light introduction parts is formed. The entire operation panel is illuminated so that it is light and low with respect to the illuminance of the spot light, so that not only can the entire operation panel be illuminated efficiently, but switches that need to be recognized more reliably. In contrast, there is an advantage that operation errors can be greatly reduced by brightly illuminating with spot light.

  In addition, the operation panel peripheral wall is provided so as to surround the operation panel, so there is little leakage of light to the outside, and the operation panel can be used even when it is mistaken for a tally or when unnecessary light must be cut off. Since the surface direction can be illuminated, the switches on the operation panel can be reliably recognized and operated.

  Furthermore, when the light introduction part is configured in a slit shape, since light from the light source can be introduced from the slit shape part, the panel material of the operation panel can be produced not only with transparent resin but also with metal, There are advantages such as improved electrical shielding performance and improved strength.

  In addition, the shape of the light guide on the peripheral wall of the operation panel has a bowl shape, or has a reflective surface with a predetermined angle with respect to the normal of the operation panel, so that the light from the light source can be efficiently It can be guided, and the illumination range in the front surface direction of the operation panel and the light intensity distribution can be changed according to the design. Further, since there is no need to induce light using a conventional V-groove panel or printing panel, the manufacturing cost can be reduced.

  In addition, the number of light sources and light guides can be appropriately set according to the size of the operation panel, the amount of light to be illuminated, and the like, so that the convenience of operation is further increased.

  In addition, by fitting a translucent member near the exit of the light guide space, the amount of light illuminated in the front surface direction of the operation panel can be adjusted, and the light source portion and the inside of the apparatus can be adjusted. It is also possible to prevent contamination and moisture from entering.

  In addition, since the operation panel peripheral wall is provided so as to surround the operation panel, not only light leaks to the outside, but also when the height of the operation panel peripheral wall is set higher than the switches, the operation panel And can protect the switches from damage. For example, when replacing the lens of the imaging device, the surface on which the operation panel is placed may be placed on the ground, but since there is an operation panel peripheral wall, the probability that the switches directly contact the ground becomes extremely low. The operation panel and switches can be protected from damage.

A first embodiment of an operation panel illumination mechanism according to the present invention will be described with reference to the drawings. FIG. 1 shows a configuration of the operation panel illumination mechanism 10, FIG. 2 shows a perspective view of the operation panel illumination mechanism 10, and FIG. 3 shows an operation panel peripheral wall 15 that is one of the components of the operation panel illumination mechanism 10. Is shown.
As shown in FIG. 1, the operation panel illumination mechanism 10 includes a light introduction portion 14 that introduces light from a light source 13 provided on the back side provided in the operation panel 11 to the front side, and an operation panel peripheral wall 15. The light source 13 and switches are arranged on a substrate 12 attached to the back side of the operation panel 11.
Further, as shown in FIG. 3, the operation panel peripheral wall 15 has two light guide portions 16 formed on the upper portion of the operation panel peripheral wall 15.

  As the light source 13, a light emitting diode is usually used because of its low power consumption, compactness, long life, and the like. An incandescent bulb may be used when it is desired to adjust the illuminance of the light source 13 steplessly.

  The operation panel 11 may be made of resin or metal. In the case of a metal, the electrical shielding performance is higher than that of a resin, and malfunction of switches can be prevented. Furthermore, the strength can be increased.

  On the back side of the operation panel 11, a substrate 12 is arranged with a predetermined interval, and various switches and volumes are attached to the front surface of the substrate 12. Two light sources 13 are further attached to the upper portion of the substrate 12.

  The operation panel 11 is provided with a light introducing portion 14 at a position corresponding to the light source 13 attached to the substrate 12. Further, the operation panel 11 is provided with holes for projecting various switches and volumes attached to the substrate 12 to the front side of the operation panel 11 at corresponding positions.

  The light introducing portion 14 has a horizontally long slit shape as shown in the perspective view of FIG. 2, and light from the light source 13 is introduced to the front side of the operation panel 11 through the slit. The shape of the light introducing portion 14 may be a slit shape, a circular shape, or a long hole shape. The light introduction unit 14 can also adjust the amount of light introduced from the light source 13 to the operation panel 11 and the introduction direction by changing the shape.

  In addition, when the operation panel 11 is made of a transparent resin, the operation panel 11 is made transparent only by printing the portion other than the light introduction portion 14 in black or pasting a light shielding sheet so that only the light introduction portion 14 is transparent. Light can also be introduced into the light introduction part 14 from the light source 13 disposed on the back surface.

  An operation panel peripheral wall 15 is attached to the front surface side of the operation panel 11 so as to surround the outer peripheral edge of the operation panel 11. As shown in FIG. 1, the operation panel peripheral wall 15 may be attached to the operation panel 11 with screws, or may be integrally formed with the operation panel 11. The height of the operation panel peripheral wall 15 can be arbitrarily set depending on the application. For example, by making the height of the operation panel peripheral wall 15 higher than the maximum height among the switches of the operation panel 11, for example, when the lens of the imaging device 1 is replaced, the surface on which the operation panel 11 is disposed. Even if the switch is placed on the ground, since the operation panel peripheral wall 15 is present, the probability that the switches directly come into contact with the ground is extremely low, so that the operation panel 11 can be protected from damage.

  As shown in FIGS. 1 to 3, the operation panel peripheral wall 15 has a light guide portion 16 formed at a position corresponding to the light introducing portion 14 of the operation panel 11. In the embodiment of FIG. 1, the light introducing portions 14 are provided at the two upper portions of the operation panel 11, and the light guide portions 16 are also provided at two locations.

  As for the shape of the light guide part 16 of the operation panel surrounding wall 15, the cross-sectional shape is a bowl shape like FIG.1 (e). In the light guiding path, first, light emitted from the light source 13 is introduced to the front side of the operation panel 11 while adjusting the amount of light from the light introducing portion 14 provided in the operation panel 11, and secondly, the light is emitted. Advances while reflecting the wall surface of the light guide unit 16 and is finally guided to the vicinity of the exit of the light guide unit 16 and illuminated by the switches and scales in the front surface direction of the operation panel 11.

  The light guide portion 16 has a bowl shape as shown in FIG. 1E, and light emitted from the light source 13 in a direction substantially perpendicular to the surface of the operation panel 11 is substantially parallel to the operation panel 11 in the flange portion. Since the guide is directed toward the operation panel 11 by the wall portion formed in the above, there is an advantage that the possibility of light leaking out of the operation panel 11 becomes very low. Further, since the light is guided while reflecting the wall surface of the light guide unit 16, it is possible to uniformly illuminate the operation panel 11 like indirect illumination.

  Further, as shown in FIG. 1 (f), the front surface of the operation panel 11 is also formed by forming a reflection surface 17 having a predetermined angle α with respect to the normal of the operation panel 11 in the light guide unit 16. The surface direction can be illuminated. The angle α of the reflection surface 17 is designed according to the size of the operation panel 11 and the height of the operation panel peripheral wall 15, but preferably the front surface direction of the operation panel 11 is formed so that 0 degree <α ≦ 60 degrees. Can be illuminated efficiently. In the present embodiment, the reflection surface 17 is formed with the angle α being 45 degrees. In the case of the light guide unit 16 having this shape, it is possible to recognize the switches and characters as a whole by uniformly illuminating the entire front surface of the operation panel 11. In addition, since light is more actively reflected and guided in the direction of the front surface of the operation panel 11, a usage method such as a spotlight is possible. Further, the angle α of the reflecting surface 17 can be designed according to the position where the front surface of the operation panel 11 is desired to be illuminated. For example, when it is desired to guide the operation panel 11 upward, the more the reflection surface 17 is formed at a larger angle such as 60 degrees, the more it can be reflected and guided upward.

  When the decorative panel 18 having translucency is fitted in the vicinity of the light guide exit of the light guide 16 as shown in FIGS. The amount of light illuminated in the direction can be changed. In particular, when a light emitting diode is used as the light source 13, since the directivity of light is high and fine adjustment of the light amount is difficult, it is easy to adjust the light amount by changing the light transmittance of the decorative panel 18. become. Further, when a matte-finished transparent resin or glass is used for the decorative panel 18, the front surface direction of the operation panel 11 can be illuminated more lightly.

  Further, by fitting the decorative panel 18, contamination, moisture, and the like are prevented from flowing back through the light guide unit 16 and adhering to the switches and the base disposed on the back side of the light source 13 and the operation panel 11. be able to.

  Next, FIG. 5 is a diagram showing a state in which the operation panel illumination mechanism 10 of the present invention is attached to the imaging apparatus 1, and an operation panel illumination mechanism having an operation panel 11 and an operation panel peripheral wall 14 on the back of the imaging apparatus 1. 10 is arranged. A tally 2 is provided on the upper back of the imaging apparatus 1. Although the operation panel 11 is normally disposed on the back surface of the imaging apparatus 1 as shown in FIG. 1, it may be disposed on the side surface.

As shown in FIG. 5, when the operation panel 11 and the tally 2 are arranged close to each other, the conventional illumination method often causes light to diffuse to the surroundings. Is difficult to distinguish.
However, in the case of the operation panel illumination mechanism 10 of the present invention, the light guide 16 provided on the operation panel peripheral wall 15 is configured to illuminate the front surface direction of the operation panel 11, so that light leaks to the surroundings. It has become difficult. Further, since the operation panel peripheral wall 15 surrounds the operation panel 11, the front surface direction of the operation panel 11 can be illuminated, and light leakage to the surroundings can be minimized. Therefore, there is an advantage that the possibility of being mistaken for tally 2 light or being difficult to discriminate becomes very low.

Next, a second embodiment of the operation panel illumination mechanism 10 will be described with reference to FIGS. 6 shows a configuration of the operation panel illumination mechanism 10 in a perspective view, and FIG. 7 shows a diagram of the operation panel peripheral wall 15 which is one of the components of the operation panel illumination mechanism 10.
As shown in FIG. 6, the operation panel illumination mechanism 10 includes a light introduction unit 14 that introduces light from a light source 13 provided on the back side provided on the operation panel 11 to the front side, an operation panel peripheral wall 15, and a light guide unit. The light source 13 and the switches are arranged on the substrate 12 attached to the back side of the operation panel 11.
Further, as shown in FIG. 7, the operation panel peripheral wall 15 has two light guide portions 16 formed on the upper portion of the operation panel peripheral wall 15 and one light guide portion 16 formed on the lower portion.

  On the back side of the operation panel 11, the substrate 12 is arranged with a predetermined interval, and various switches and volumes are attached to the substrate 12. Further, two light sources 13 are attached to the upper part of the substrate 12 and two parts are also attached to the lower part.

  The operation panel 11 is provided with a light introducing portion 14 at a position corresponding to the light source 13 attached to the substrate 12. In the embodiment of FIG. 6, the light source 13 is attached at two locations at the upper portion of the operation panel 11 and at two locations at the lower portion, so that the light introducing portions 14 are also provided at the upper two locations and the lower two locations correspondingly. ing.

  An operation panel peripheral wall 15 is attached to the front surface of the operation panel 11 so as to surround the outer peripheral edge of the operation panel 11. The height of the operation panel peripheral wall 15 can be arbitrarily set depending on the application. For example, when the lens of the imaging device 1 is replaced by setting the height of the operation panel peripheral wall 15 higher than the maximum height among the attached switches, the surface on which the operation panel 11 is disposed is grounded. Even if placed, the operation panel 11 can be protected from damage since the probability of the switches directly contacting the ground is extremely low because of the operation panel peripheral wall 15.

  As shown in FIGS. 6 and 7, the operation panel peripheral wall 15 has a light guide portion 16 formed at a position corresponding to the light introducing portion 14 of the operation panel 11. Light guides 16 are respectively formed in the upper two light introduction parts 14, and the light introduced from the two light introduction parts 14 is collected in the lower two light introduction parts 14. One light guide 16 having a shape that can be guided in the direction of illuminating the front surface is provided.

When the light guide 16 is provided with one light guide 16 with respect to one light introducing part 14 like the upper light guide 16, an effect like spot light can be obtained. Further, like the lower light guide unit 16, the light guide has a shape that can guide the light introduced from the two light introduction units 14 together in the direction of illuminating the front surface of the operation panel 11. If it is set as the part 16, it is also possible to illuminate the whole operation panel 11 thinly so that it may become low with respect to the illumination intensity of spotlight .

  The operation panel illumination mechanism 10 according to the present invention has the light source 13 and the light introduction part 14 arranged at two upper positions like the operation panel illumination mechanism 10 of the first embodiment, or the operation panel illumination of the second embodiment. The number of the light sources 13 can be increased or decreased according to the size of the operation panel 11 as well as the light source 13 and the light introduction unit 14 are arranged at two positions above and below like the mechanism 10. For example, the operation panel 11 The light source 13 and the light introduction part 14 can be arranged along the left and right sides as well as the upper and lower sides of the light, and the light guide part 16 can illuminate the operation panel 11 in the front surface direction.

  The operation panel illumination mechanism according to the present invention can be used not only to illuminate the operation panel but also to illuminate other display monitors and the like.
