Description

  The present invention relates to an operation device provided in a device such as a camera.

  Conventionally, an operation member such as a dial for setting a power switch of the camera and a shooting mode, or a lid member for inserting a recording medium, a battery, or the like is made of mold resin or metal, and on the surface or the periphery of these members, Indicators such as letters and pictograms are displayed by printing or the like. The user can operate the desired member with certainty by looking at these indices and perform appropriate camera photography.

  By the way, when using the camera in the dark, for example when shooting stars, night scenes, fireworks, etc. There has been proposed a camera that displays a set photographing mode on a liquid crystal display panel with a backlight.

In addition, the operation unit component is formed of a transparent or translucent material so that the operation indicator can be confirmed without turning on the backlight switch, and a phosphorescent material is disposed on the back side of the operation unit component. Some cameras display indicators. (For example, see Patent Document 1)
JP-A-10-091264

  However, when a fluorescent material is used for printing the operation index, it does not emit light if there is no light source around it. Further, when the phosphorescent material is disposed on the back side of the operation member, there is a problem that the phosphorescent material does not emit light if left in the dark for a long time. In addition, when using a liquid crystal display panel with a backlight, the backlight switch must be operated each time the liquid crystal display is viewed, which is cumbersome and requires a power source to turn on the backlight. Therefore, there is a problem in that the indicator of the indicator that needs to be illuminated (for example, the battery lid) cannot be illuminated even when the battery is not inserted.

  Accordingly, an object of the present invention is to provide an operation device capable of reliably confirming an operation index in the dark without requiring a power source and preventing erroneous operation of the operation member, and a device such as a camera equipped with the operation device. It is.

  In order to achieve the above object, the structure for realizing the object of the invention according to the present application is a transparent or translucent material in an operation device having an operation unit component on which an operation index is displayed. The impact light emitting LED is disposed on the back surface side of the operation unit constituent member, and the phosphorescent member is disposed around the impact light emitting LED.

  According to the present invention, in an operating device having an operation unit constituent member having an operation index displayed on the surface, the operation unit constituent member is formed of a transparent or translucent material, and a shock emission is generated on the back side of the operation unit constituent member. By illuminating the impact light emitting LED by the impact of operating the operation member with the LED, the operation indicator can be confirmed reliably in the dark without the need for a power source, and a phosphorescent member is arranged around the impact light emitting LED. By doing so, it is possible to provide an operating device and a device such as a camera equipped with the operating device that allow the operation index to be confirmed even after the impact light-emitting LED is turned off, thereby preventing erroneous operation of the operating member.

Example 1
A first embodiment of the present invention will be described below with reference to FIGS.

  1 to 3 show an embodiment according to the present invention. FIG. 1 is a sectional view showing a state in which the mode dial is attached to the camera body, FIG. 2 is a front view of the mode dial, and FIG. It is a reverse view of a dial.

  1 to 3, the mode dial 1 is rotatably attached to the main body 4 with a mode dial rotating shaft 1c. Reference numeral 1a denotes an index made of a transparent material having various modes printed on the surface, and is attached to the mode dial 1 by bonding or the like. The impact light emitting LED 2 is built in the mode dial 1 so that the light from the LED light emitting portion 2a passes through the indicator 1a. A phosphorescent member 3 is arranged around the LED light emitting unit 2a at a portion other than the index 1a. The spring 4 b is attached to the main body 4 and biases the ball 4 a toward the mode dial 1. The sphere 4 a is in contact with the impact light emitting LED 2 from the LED contact hole 1 b of the mode dial 1.

  When the mode dial 1 is operated (rotated) by the photographer's hand, the ball 4a that has been in contact with the impact light emitting LED 2 from the LED contact hole 1b is once pushed into the main body 4 side. When the mode dial 1 further rotates and rotates to another index position, the ball 4a contacts the impact light emitting LED 2 for displaying the index from the LED contact hole 1b opposed to the index by the force of the spring 4b. Due to this impact, the LED light emitting portion 2a of the impact light emitting LED 2 emits light. A part of the emitted light illuminates the indicator 1a as it is to let the operator know where the mode dial is located. Moreover, the light which did not permeate | transmit the parameter | index 1a as it is among emitted light is absorbed by the luminous member 3, and the luminous component 3 shines, and the parameter | index 1a will be illuminated for a while.

(Example 2)
Next, a second embodiment of the present invention will be described with reference to FIGS.

  4 to 7 show a second embodiment according to the present invention, FIG. 4 is a perspective view showing a state in which the battery cover is open, and FIG. 5 is a cross-sectional view showing a state in which the battery cover is closed, FIG. 6 is a cross-sectional view showing a state where the battery cover is being opened, and FIG. 7 is a cross-sectional view showing a state where the battery cover is being opened.

  4 to 7, the battery lid 5 is rotatably attached to the main body 8 with a rotation shaft (not shown). 5a is an index made of a transparent material, and is attached to the battery lid 5 by adhesion or the like. The impact light emitting LED 6 is built in the battery cover 5 so that the light from the LED light emitting portion 6a passes through the indicator 5a. A phosphorescent member 7 is disposed around the LED light emitting portion 6a in a portion other than the index 5a. The spring 8b is attached to the main body 8, and urges the ball 8a in a direction perpendicular to the surface on which the battery cover 5 is attached. When the battery cover 5 is closed, the sphere 8 a is pushed into the main body 8 by a sphere holding part 5 b that is a part of the battery cover 5.

  When the battery lid 5 is opened by the photographer's hand and changes from the state shown in FIG. 6 to the state shown in FIG. 7, the ball 8a starts to move in a direction perpendicular to the surface to which the battery lid 5 is attached by the force of the spring 8b. When 5 is opened to the vertical, the impact light emitting LED 6 is contacted. Due to this impact, the LED light emitting portion 6a of the impact light emitting LED 6 emits light. A part of the emitted light illuminates the indicator 5a as it is to inform the operator of the battery insertion direction. Further, the light that does not pass through the indicator 5a as it is is absorbed by the phosphorescent member 7, and the indicator 5a is illuminated for a while when the phosphorescent member 7 shines.
