In the following description, when the rifle scope is described as up / down, left / right, front / rear, horizontal, vertical, etc., it is observed in a state where the rifle scope is attached to the rifle (hereinafter referred to as a use state). It is based on the positional relationship when the direction toward the target object is the front direction and the direction toward the user is the rear direction.

  FIG. 1 is a perspective view of a rifle scope 1 according to the present embodiment. The rifle scope 1 includes a cylindrical housing 2. The housing 2 includes an object side portion 3 on the object side (ie, the front side), an eyepiece side portion 4 on the user side (ie, the back side), and an intermediate portion that connects the object side portion 3 and the eyepiece side portion 4. It is composed of five. FIG. 1 shows an example in which the objective side portion 3 and the eyepiece side portion 4 are configured to have a larger diameter than the intermediate portion 5. However, the diameters of the objective side portion 3 and the intermediate portion 5 may be the same.

  An objective lens 6 (schematically indicated by a dotted line in FIG. 1) directed to an object to be observed is provided inside the objective side portion 3 of the housing 2. An eyepiece 7 directed toward the user's eye is provided inside the eyepiece side portion 4 of the housing 2.

  A fixing member (not shown) for fixing the rifle scope 1 to the rifle is provided below the intermediate portion 5 of the housing 2. The rifle scope 1 is attached to the rifle through this fixing member.

  A zoom ring 8 is provided at the front end of the eyepiece side portion 4 of the housing 2. A zoom lens 19 (FIG. 2) is provided inside the housing 2, and when the zoom ring 8 is rotated, the zoom lens 19 moves in the direction of the optical axis 11 and the magnification of the rifle scope 1 changes. It is configured as follows.

  The eyepiece side portion 4 of the housing 2 has a configuration in which a cylindrical portion 9 and a convex portion 10 protruding upward from the cylindrical portion 9 are integrally formed. The convex portion 10 has an upper surface 12 that is a surface substantially parallel to a horizontal plane passing through the optical axis 11 of the rifle scope 1, and a right side surface 13 and a left side surface 14 that are surfaces substantially parallel to a vertical surface passing through the optical axis 11. . The right side surface 13 and the left side surface 14 are provided to face each other with the optical axis 11 in between. A battery accommodating part (not shown) for accommodating the battery is provided inside the convex part 10, and a lid 16 for opening and closing the battery accommodating part is provided on the upper surface 12 of the convex part 10. One push switch is provided on each of the right side surface 13 and the left side surface 14 of the convex portion 10. Hereinafter, the push switch on the right side surface 13 is called a right push switch 17, and the push switch on the left side surface 14 is called a left push switch 18. Note that the right push switch 17 and the left push switch 18 are switches that are configured to return to the initial state in which they can be newly operated by themselves immediately after being pressed, and when they are no-load again, are repeatedly pressed repeatedly. Operation is configured to be possible.

  FIG. 2 is a diagram schematically showing the internal configuration of the rifle scope 1. As shown in FIG. 2, the rifle scope 1 is provided with an objective lens 6, a zoom lens 19, a display device 20, and an eyepiece lens 7 on the optical axis 11. In order to simplify FIG. 2, the objective lens 6, the zoom lens 19, and the eyepiece lens 7 are illustrated as single lenses, but these may be configured by a plurality of lens groups. The display device 20 is configured by, for example, a transmissive liquid crystal display or an organic EL display. Incident light from the objective lens 6 passes through the zoom lens 19, forms an image on the display device 20, and is enlarged by the eyepiece lens 7. Therefore, the user can observe the image of the observation object from the objective lens 6 and the display screen of the display device 20 through the eyepiece lens 7 in an overlapping manner.

  The rifle scope 1 includes a control device 21. The control device 21 includes a CPU and other peripheral circuits. The right push switch 17 and the left push switch 18 each output a push signal to the control device 21 when pressed. The control device 21 performs display control of the display device 20 based on pressing signals from the right push switch 17 and the left push switch 18.

  Next, the display control of the display device 20 executed by the control device 21 will be specifically described. FIG. 3 is a diagram for explaining the display screen 30 of the display device 20. As shown in FIG. 3A, the display screen 30 of the display device 20 has a circular shape, and a reticle 40 for aiming at the observation object is displayed on the display screen 30. The reticle 40 includes a center point displayed at the center of the field of view of the rifle scope 1 (that is, on the optical axis 11), a horizontal line passing through the center and dividing the field of view in the horizontal direction, and passing through the center in the vertical direction. It consists of a crosshair consisting of vertical lines to divide.

  When one of the right push switch 17 and the left push switch 18 is pressed while the reticle 40 is not displayed, the control device 21 sets the reticle 40 at a predetermined luminance on the display device 20. Display. Therefore, in the rifle scope 1, the reticle 40 can be displayed regardless of which of the right push switch 17 and the left push switch 18 is pressed by the user. Therefore, the user does not need to consider whether the display switch of the reticle 40 is left or right, so that the reticle 40 can be displayed quickly.

  When only the right push switch 17 is pressed while the reticle 40 is displayed, the control device 21 increases the luminance of the center point of the reticle 40 by a predetermined amount. When only the right push switch 17 is pressed for a long time, the control device 21 increases the luminance at the center point of the reticle 40 by an amount corresponding to the long press time. In addition, while the right push switch 17 is pressed and the brightness of the center point of the reticle 40 is increased, the control device 21 displays “+” on the right side of the vertical line of the reticle 40 as shown in FIG. The increase mark 50 made up of “ Thereby, it can be notified to the user that the brightness of the center point of the reticle 40 is increased. Note that the control device 21 displays the increase mark 50 only while the right push switch 17 is pressed, and hides the increase mark 50 when the right push switch 17 is in a no-load state to observe the object. Do not disturb.

  When using the rifle scope 1, the user may be wearing gloves, and even if the right push switch 17 is pressed while wearing the gloves, it may be difficult to know whether the right push switch 17 has been pressed properly. . Therefore, it may be difficult to understand at a glance whether the user can increase the brightness of the center point of the reticle 40 by observing the reticle 40. However, in the rifle scope 1 of the present embodiment, by displaying the increase mark 50, the user can clearly recognize that the brightness of the center point of the reticle 40 is increased by his own pressing operation. Further, in the rifle scope 1 of the present embodiment, by displaying the increase mark 50 on the right side of the vertical line of the reticle 40, the luminance at the center point of the reticle 40 is increased by pressing the right push switch 17. It is possible to notify more clearly.

  An upper limit value is set for the luminance at the center point of the reticle 40. That is, the luminance at the center point of the reticle 40 can be increased up to the upper limit value, but cannot be larger than the upper limit value. When the brightness at the center point of the reticle 40 reaches the upper limit value, the control device 21 does not increase the brightness at the center point of the reticle 40 even if the right push switch 17 is pressed, and keeps the upper limit value. In addition, when the right push switch 17 is pressed while the brightness of the center point of the reticle 40 is the upper limit value, the control device 21 causes the increase mark 50 to blink. That is, when the brightness of the center point of the reticle 40 reaches the lower limit value while the right push switch 17 is being pressed down, the control device 21 switches the increase mark 50 from the lighting display to the blinking display. Thereby, it is possible to notify the user that the luminance of the center point of the reticle 40 is the upper limit value.

  On the other hand, when only the left push switch 18 is pressed while the reticle 40 is displayed, the control device 21 decreases the luminance at the center point of the reticle 40 by a predetermined amount. When only the left push switch 18 is pressed for a long time, the control device 21 decreases the luminance at the center point of the reticle 40 by an amount corresponding to the long press time. Further, the control device 21 “−” on the left side of the vertical line of the reticle 40 as shown in FIG. 3C while the left push switch 18 is pressed to decrease the luminance of the center point of the reticle 40. A reduction mark 60 made up of the characters is lit up. As a result, the user can clearly recognize that the brightness of the center point of the reticle 40 has decreased due to his own pressing operation. Further, in the rifle scope 1 of the present embodiment, the reduction mark 60 is displayed on the left side of the vertical line of the reticle 40, so that the luminance at the center point of the reticle 40 is reduced by the pressing operation of the left push switch 18. It is possible to notify more clearly.

  Note that the control device 21 displays the decrease mark 60 only while the left push switch 18 is pressed, and when the left push switch 18 is in an unloaded state, hides the decrease mark 60 and observes the object. Do not disturb.

  In addition, a lower limit value is set for the luminance at the center point of the reticle 40. That is, the luminance at the center point of the reticle 40 can be reduced to the lower limit value, but cannot be made smaller than the lower limit value. When the brightness at the center point of the reticle 40 reaches the lower limit value, the control device 21 does not decrease the brightness at the center point of the reticle 40 even if the left push switch 18 is pressed, and keeps the lower limit value. Further, when the left push switch 18 is pressed while the brightness of the center point of the reticle 40 is at the lower limit value, the control device 21 causes the decrease mark 60 to blink. That is, when the brightness of the center point of the reticle 40 reaches the lower limit value while the left push switch 18 is being pressed down, the control device 21 switches the decrease mark 60 from the lighting display to the blinking display. Thereby, it is possible to notify the user that the luminance at the center point of the reticle 40 is the lower limit value.

  Further, when the right push switch 17 and the left push switch 18 are simultaneously pressed while the reticle 40 is displayed, the control device 21 hides the reticle 40. Since the right push switch 17 and the left push switch 18 are provided in the vicinity of the zoom ring 8, there is a possibility of erroneous operation when the zoom ring 8 is operated. However, since the right push switch 17 and the left push switch 18 are provided on the right side surface 13 and the left side surface 14 of the convex portion 10, respectively, the possibility that both switches are unintentionally pressed is very low. Therefore, the possibility that the user accidentally hides the reticle 40 is very low.

According to the embodiment described above, the following operational effects can be obtained.
(1) The rifle scope 1 includes an objective lens 6 directed to an object to be observed, a display device 20 on which a reticle 40 for aiming the object is displayed, and an image of the object from the objective lens 6. And the eyepiece 7 that can be observed by superimposing the reticle 40 and the right push switch 17 that can be operated continuously and repeatedly, and instructing an increase in the brightness of the center point of the reticle 40, and repeatedly. Left push switch 18 that can be operated and instructed to decrease the brightness of the center point of reticle 40, and that the brightness of the center point of reticle 40 is increased in response to an operation signal from right push switch 17, and left push switch The control device 21 reduces the luminance at the center point of the reticle 40 in response to an operation signal from 18, and the luminance at the center point of the reticle 40 is the upper limit value. When the push switch 17 is operated, and when the left push switch 18 is operated in a state where the brightness of the center point of the reticle 40 is the lower limit value, the brightness of the center point of the reticle 40 is the limit value. And a control device 21 that causes the display device 20 to display information indicating that the increase mark 50 or the decrease mark 60 is blinking. Accordingly, when the luminance at the center point of the reticle 40 reaches the limit value, the user can recognize that the luminance at the center point of the reticle 40 is the limit value.

(2) In the rifle scope 1 of (1) above, the control device 21 increases the brightness of the center point of the reticle 40 while the right push switch 17 is operated to increase the brightness of the center point of the reticle 40. While the information (increase mark 50) indicating that the image is being displayed is displayed on the display device 20 and the left push switch 18 is operated to decrease the brightness at the center point of the reticle 40, the brightness at the center point of the reticle 40 is displayed. Since the information (decrease mark 60) indicating that the brightness is reduced is displayed on the display device 20, the user can clearly recognize the increase or decrease in the luminance of the center point of the reticle 40.

(3) In the rifle scope 1 of (2) above, the housing 2 in which the objective lens 6, the display device 20, and the eyepiece lens 7 are accommodated, and the right side provided in the housing 2 and provided with the right push switch 17. A reticle 13 is provided at the center of the field of view of the rifle scope 1 and the luminance is increased or decreased. And a horizontal line that divides the field of view in the horizontal direction through the center and a cross line that consists of a vertical line that divides the field of view in the vertical direction through the center. The control device 21 is operated by the right push switch 17. While the brightness of the center point of the reticle 40 is being increased, the increase mark 50 is displayed on the right side surface 13 side of the vertical line of the reticle 40, and the brightness is the upper limit value. When the push switch 17 is operated, the display mode of the increase mark 50 is changed (switching from the lighting display state to the blinking display state) to indicate that the luminance is the limit value, and the left push switch 18 is operated. While the brightness of the center point of the reticle 40 is being reduced, the decrease mark 60 is displayed on the left side 14 side of the vertical line of the reticle 40, and the left push switch 18 is operated in a state where the brightness is the lower limit value. In such a case, the display mode of the reduction mark 60 is changed (switched from the lighting display state to the blinking display state) to indicate that the luminance is a limit value. As described above, the correspondence between the position of the right push switch 17 and the display position of the increase mark 50 indicates that the brightness of the center point of the reticle 40 is increased by pressing the right push switch 17. It can be clearly recognized. Similarly, the correspondence between the position of the left push switch 18 and the display position of the decrease mark 60 indicates that the brightness of the center point of the reticle 40 is decreased by the pressing operation of the left push switch 18. Can be clearly recognized.

(Modification 1)
As shown in FIG. 4, a bright line 70 indicating the luminance level of the center point of the reticle 40 may be displayed on the display screen 30 of the display device 20. The bright line 70 is a vertical line, and is displayed above the center point of the reticle 40 and the horizontal line, for example. In addition, the control device 21 causes the display screen 30 to display a frame indicating the moving area 71 along which the bright line 70 moves together with the bright line 70. The moving area 71 is a rectangular area extending in the left-right direction across the vertical line of the reticle 40, and the right end of the moving area 71 corresponds to the upper limit value (MAX) of the luminance of the center point of the reticle 40. The left end portion of the moving area 71 corresponds to the lower limit value (MIN) of the luminance at the center point of the reticle 40.

  When only the right push switch 17 is pressed while the reticle 40 is displayed, the control device 21 increases the luminance of the center point of the reticle 40 and causes the display device 20 to display the bright line 70, thereby increasing the luminance. Accordingly, the bright line 70 is moved in the right direction within the movement region 71. Thereby, it can be notified to the user that the brightness of the center point of the reticle 40 is increased. Further, by moving the bright line 70 in the right direction, it is possible to notify that the brightness of the center point of the reticle 40 is increased by pressing the right push switch 17 in a more easily understandable manner.

  In addition, when the right push switch 17 is pressed while the brightness of the center point of the reticle 40 is the upper limit value, the control device 21 displays the bright line 70 but does not change the brightness of the center point of the reticle 40. The bright line 70 is kept stationary at the right end of the moving area 71. That is, when the luminance of the center point of the reticle 40 reaches the upper limit value while the right push switch 17 is continuously pressed, the control device 21 stops the movement of the bright line 70 in the right direction. Thereby, it is possible to notify the user that the luminance of the center point of the reticle 40 is the upper limit value.

  On the other hand, when only the left push switch 18 is pressed in a state where the reticle 40 is displayed, the control device 21 decreases the luminance of the center point of the reticle 40 and causes the display device 20 to display the bright line 70, and the luminance. The bright line 70 is moved in the left direction within the moving area 71 in accordance with the decrease in the amount of the light. Thereby, it can be notified to the user that the brightness of the center point of the reticle 40 is reduced. Further, by moving the bright line 70 in the left direction, it is possible to more easily notify that the luminance at the center point of the reticle 40 has been reduced by pressing the left push switch 18.

  Further, when the left push switch 18 is pressed while the brightness of the center point of the reticle 40 is at the lower limit value, the control device 21 displays the bright line 70 but does not change the brightness of the center point of the reticle 40. The bright line 70 is kept stationary at the left end of the moving area 71. That is, when the brightness of the center point of the reticle 40 reaches the lower limit value while the left push switch 18 is being pressed down, the control device 21 stops moving the bright line 70 in the left direction. Thereby, it is possible to notify the user that the luminance at the center point of the reticle 40 is the lower limit value.

  The control device 21 displays the bright line 70 only while the right push switch 17 or the left push switch 18 is pressed, and does not display the bright line 70 when the right push switch 17 and the left push switch 18 are in an unloaded state. Thus, the observation of the object is not disturbed.

(Modification 2)
As shown in FIG. 5, a luminance indicator 80 indicating the luminance level of the center point of the reticle 40 may be displayed on the display device 20. The luminance indicator 80 has a configuration in which a plurality of rectangles are arranged in the horizontal direction across the vertical line of the reticle 40, and the right end portion of the luminance indicator 80 corresponds to the upper limit value (MAX) of the luminance at the center point of the reticle 40. The left end of the luminance indicator 80 corresponds to the lower limit value (MIN) of the luminance at the center point of the reticle 40.

  When only the right push switch 17 is pressed in a state where the reticle 40 is displayed, the control device 21 increases the luminance of the center point of the reticle 40 and causes the display device 20 to display the luminance indicator 80. In accordance with the increase, the rectangle of the luminance indicator 80 is painted in order from left to right. In other words, the control device 21 moves the right end of the luminance indicator 80 in the right direction without moving the left end in accordance with the increase in the luminance, thereby moving the fill area to the right. Spread in the direction. Therefore, the position of the right end of the filled area indicates the luminance level of the center point of the reticle 40. With such a display, the rifle scope 1 can notify the user that the brightness of the center point of the reticle 40 is increased. In addition, by sequentially painting the rectangle of the luminance indicator 80 from left to right, it is possible to more easily notify that the luminance of the center point of the reticle 40 is increased by pressing the right push switch 17. it can.

  Further, when the right push switch 17 is pressed while the luminance at the center point of the reticle 40 is the upper limit value, the control device 21 displays the luminance indicator 80, but does not change the luminance at the center point of the reticle 40. The rectangle of the luminance indicator 80 is not changed from the filled state. That is, when the brightness of the center point of the reticle 40 reaches the upper limit value while the right push switch 17 is being pressed down, the control device 21 changes the movement of the right end of the painted area of the brightness indicator 80 to the brightness indicator 80. Keep it stationary at the right end. With such a display, the rifle scope 1 can notify the user that the brightness of the center point of the reticle 40 is the upper limit value.

  On the other hand, when only the left push switch 18 is pressed while the reticle 40 is displayed, the control device 21 decreases the luminance of the center point of the reticle 40 and causes the display device 20 to display the luminance indicator 80. As the luminance decreases, the filled rectangle of the luminance indicator 80 is blanked in order from right to left. In other words, the control device 21 moves the right end portion to the left without moving the left end portion in accordance with the decrease in luminance, thereby moving the fill region to the left. Narrow in the direction. With such a display, the rifle scope 1 can notify the user that the brightness of the center point of the reticle 40 is being reduced. In addition, by making the filled rectangle of the luminance indicator 80 blank in order from the right to the left, it is easier to understand that the luminance of the center point of the reticle 40 is reduced by pressing the left push switch 18. Can be notified.

  Further, when the left push switch 18 is pressed while the luminance at the center point of the reticle 40 is at the lower limit value, the control device 21 displays the luminance indicator 80, but does not change the luminance at the center point of the reticle 40. The luminance indicator 80 is not changed from a state in which all the rectangles are blank (not filled). That is, when the luminance of the center point of the reticle 40 reaches the lower limit value while the left push switch 18 is being pressed down, the control device 21 changes the movement of the right end of the painted area of the luminance indicator 80 to the luminance indicator 80. The filled area is not displayed by making it stand still at the left end of. Thereby, it is possible to notify the user that the luminance at the center point of the reticle 40 is the lower limit value.

  Note that the control device 21 displays the luminance indicator 80 only while the right push switch 17 or the left push switch 18 is pressed, and displays the luminance indicator 80 when the right push switch 17 and the left push switch 18 are in an unloaded state. Hide it so that it does not interfere with the observation of the object.

(Modification 3)
As shown in FIG. 6, a luminance counter 90 indicating the luminance level of the center point of the reticle 40 may be displayed on the display device 20. The luminance counter 90 is displayed above the center point of the reticle 40 and the horizontal line, for example. The luminance counter 90 displays the luminance level at the center point of the reticle 40 as a numerical value from “−50” to “+50” with a predetermined luminance value as a reference value “0”.

  When only the right push switch 17 is pressed while the reticle 40 is displayed, the control device 21 increases the luminance of the center point of the reticle 40 and displays the luminance counter 90, and according to the increase in the luminance. The numerical value of the brightness counter 90 is increased. Thereby, it can be notified to the user that the brightness of the center point of the reticle 40 is increased. Further, when the right push switch 17 is pressed while the brightness of the center point of the reticle 40 is the upper limit value, the control device 21 displays the brightness counter 90, but does not change the brightness of the center point of the reticle 40. The numerical value of the luminance counter 90 is not changed. That is, when the brightness of the center point of the reticle 40 reaches the upper limit value while the right push switch 17 is being pressed down, the control device 21 stops increasing the value of the brightness counter 90. Thereby, it is possible to notify the user that the luminance of the center point of the reticle 40 is the upper limit value.

  On the other hand, when only the left push switch 18 is pressed while the reticle 40 is displayed, the control device 21 reduces the luminance at the center point of the reticle 40 and displays the luminance counter 90 to reduce the luminance. Accordingly, the numerical value of the luminance counter 90 is decreased. Thereby, it can be notified to the user that the brightness of the center point of the reticle 40 is reduced. Further, when the left push switch 18 is pressed while the brightness of the center point of the reticle 40 is the lower limit value, the control device 21 displays the brightness counter 90, but does not change the brightness of the center point of the reticle 40. The numerical value of the luminance counter 90 is not changed. That is, when the brightness of the center point of the reticle 40 reaches the lower limit value while the left push switch 18 is continuously pressed, the control device 21 stops the numerical value of the brightness counter 90 from being lowered. Thereby, it is possible to notify the user that the luminance at the center point of the reticle 40 is the lower limit value.

(Modification 4)
In the rifle scope 1, it may be notified by sound that the luminance at the center point of the reticle 40 is a limit value (upper limit value or lower limit value). The rifle scope 1 in this case is provided with sound emitting means such as a speaker. When the right push switch 17 or the left push switch 18 is operated in a state where the brightness of the center point of the reticle 40 reaches a limit value, the control device 21 outputs a predetermined sound signal (for example, a warning sound) to the speaker. . As a result, a predetermined sound is emitted from the speaker, and the user can recognize that the luminance at the center point of the reticle 40 is the limit value.

(Modification 5)
In the rifle scope 1, the fact that the luminance at the center point of the reticle 40 is a limit value (upper limit value or lower limit value) may be notified by vibration. In this case, the rifle scope 1 is provided with vibration means such as a vibrator. The control device 21 vibrates the vibrator when the right push switch 17 or the left push switch 18 is operated in a state where the luminance at the center point of the reticle 40 reaches a limit value. This allows the user to recognize that the luminance at the center point of the reticle 40 is the limit value.

(Modification 6)
In the above-described embodiment, an example has been described in which the increase mark 50 or the decrease mark 60 is switched from lighting display to blinking display to notify that the luminance at the center point of the reticle 40 has reached the limit value. However, the control device 21 blinks the increase mark 50 or the decrease mark 60 while increasing or decreasing the luminance at the center point of the reticle 40, and starts blinking when the luminance at the center point of the reticle 40 reaches a limit value. By switching to the lighting display, it may be notified that the luminance at the center point of the reticle 40 has reached the limit value. Further, the control device 21 may notify that the luminance at the center point of the reticle 40 has reached the limit value due to the change in the other display mode of the increase mark 50 or the decrease mark 60. For example, by changing the color of the increase mark 50 or the decrease mark 60, it may be notified that the brightness of the center point of the reticle 40 has reached a limit value.

(Modification 7)
In the above-described embodiment, the example in which the fact is notified when the luminance at the center point of the reticle 40 reaches the upper limit value and the lower limit value has been described. However, the notification may be made only when the brightness of the center point of the reticle 40 reaches the upper limit value, or may be notified only when the brightness of the center point of the reticle 40 becomes the lower limit value. .

(Modification 8)
In the above-described embodiment, the example in which only the luminance at the center point of the reticle 40 is increased or decreased has been described. However, the luminance of the entire reticle 40 (that is, including the cross line in addition to the center point) may be increased or decreased. .

(Modification 9)
In the above-described embodiment, the example in which the right push switch 17 and the left push switch 18 are provided as the operation means for instructing the increase / decrease of the luminance at the center point of the reticle 40 has been described. However, other operation means such as a rotary switch and a lever switch may be provided as operation means for instructing increase / decrease in luminance at the center point of the reticle 40.

(Modification 10)
In the above-described embodiment, an example has been described in which the luminance at the center point of the reticle 40 is increased when the right push switch 17 is pressed, and the luminance at the center point of the reticle 40 is decreased when the left push switch 18 is pressed. However, the functions of these switches may be interchanged.
