Therefore, each mode can be easily switched by simply moving the left reflecting mirror 23 and the right reflecting mirror 24.

  FIG. 4 is a control block diagram of the binoculars 1. As shown in FIG. 4, the control unit 35 detects the states of operation members such as the power button 2, the focus button 3, the select button 4, the start button 5, the switching lever 7, and the memory button 8, and The state is also detected. Further, the control unit 35 controls a mirror driving unit (not shown) of the information display unit 6, the focus lens moving unit 15, the left display unit 19 and the right display unit 20, the left reflection mirror 23 and the right reflection mirror 24. The binoculars 1 further include a storage unit 25 that stores the positions of the left focus lens 13 and the right focus lens 14 described above.

  The left eyepiece lens 9 and the right eyepiece lens 10 correspond to the “eyepiece lens” in the claims, and the left objective lens 11 and the right objective lens 12 correspond to the “objective lens” in the claims. The left focus lens 13 and the right focus lens 14 correspond to the “focus lens” in the claims, and the focus lens moving unit 15, the left display unit 19, the right display unit 20, the left reflection mirror 23, the right reflection mirror 24, The control unit 35 corresponds to a “recovery operation unit” in the claims. The detection unit 16 and the control unit 35 correspond to “detection unit” in the claims, and the control unit 35 corresponds to “control unit” and “accepting unit” in the claims. The storage unit 25 and the control unit 35 correspond to a “storage unit” in the claims.

In the binoculars 1 configured as described above, when the power button 2 is turned on, the control unit 35 detects this, and waits until the mode and menu are set and the start button 5 is pressed. The mode set here is one of the above-described “binocular mode” and “eye fatigue recovery mode”, and is set by the switching lever 7.
When the start button 5 is pressed, the control unit 35 controls each unit as follows according to the set mode.

  First, when the binocular mode is set, the control unit 35 controls the focus lens moving unit 15 to set the left focus lens 13 and the right focus lens 14 to an initial state. Then, as described in FIG. 3B, the left reflecting mirror 23 and the right reflecting mirror 24 are retracted from the optical axes of the left eyepiece lens 9 and the right eyepiece lens 10, and the left objective lens 11 and the right objective lens 12 are moved to the left eyepiece. They are arranged on the optical axes of the lens 9 and the right eyepiece 10. By arranging in this way, the light flux is guided between the left objective lens 11 and the right objective lens 12 and the left eyepiece lens 9 and the right eyepiece lens 10, and the observer uses the left eyepiece lens 9 and the right eyepiece lens 10. Through this, a distant object can be observed.

In the binocular mode, the observer can perform the desired observation by operating the focus button 3 to adjust the focus. At this time, when the memory button 8 is operated by the observer, the control unit 35 detects the positions of the left focus lens 13 and the right focus lens 14 when the focus adjustment is performed via the detection unit 16, and Store in the storage unit 25.
On the other hand, when the eye fatigue recovery mode is set, the control unit 35 first prompts the observer to adjust the focus. Specifically, a message such as “Please operate the focus button 3 to adjust the focus” is displayed on the information display unit 6. Then, the observer looks into the left display unit 19 and the right display unit 20 from the eyepiece lens side, and when the focus is adjusted by the observer, the control unit 35 passes the detection unit 16 through the left focus lens 13 and the right display unit. The position of the focus lens 14 is detected. Then, the focus lens moving unit 15 is controlled to determine the position of the focus lens before the eye fatigue recovery operation. At this time, when the memory button 8 is operated by the observer, the control unit 35 detects the positions of the left focus lens 13 and the right focus lens 14 when the focus adjustment is performed via the detection unit 16, and Store in the storage unit 25.

Next, the control unit 35 inserts the left reflection mirror 23 and the right reflection mirror 24 on the optical axes of the left eyepiece lens 9 and the right eyepiece lens 10 as described with reference to FIG. 3C. By arranging in this way, the light flux is guided between the left display unit 19 and the right display unit 20 and the left eyepiece lens 7 and the right eyepiece lens 8.
Then, the control unit 35 displays an image for restoring eye fatigue on the left display unit 19 and the right display unit 20. The image for eye fatigue recovery is a pattern (for example, an airplane, a car, etc.) that becomes a target (object to collect the observer's line of sight) at a position (near the center) where the observer can easily recognize the line of sight. It is an image including a pictorial diagram of what can be moved back and forth. Such an image is recorded in advance in a memory (not shown) in the control unit 35.

  Then, the control unit 35 controls the focus lens moving unit 15 to reciprocate the left focus lens 13 and the right focus lens 14 for a predetermined time. By reciprocating the left focus lens 13 and the right focus lens 14 in this way, the position of the image observed by the observer is changed in the optical axis direction of the observer's eyes. Therefore, it is possible to promote the movement of the ciliary muscles of the observer's eyes. Note that when performing such an eye fatigue recovery operation, the left focus lens 13 and the right focus lens 14 are moved in a wider range than when performing focus adjustment. Each movement range may be overlapped or separated. Then, when the predetermined operation is finished, the control unit 35 returns each unit to the initial state.

Hereinafter, the operation of each part when using the binoculars 1 after the second time, which is a feature of the present invention, will be described.
When the observer uses the binoculars 1 after the second time, when the mode or menu is set and the start button 5 is pressed, the control unit 35 first adjusts the focus in the storage unit 25 in each mode. It is determined whether or not the positions of the left focus lens 13 and the right focus lens 14 are stored. When the positions of the left focus lens 13 and the right focus lens 14 are stored, the stored positions are read from the storage unit 25 and the focus lens moving unit 15 is controlled to control the left focus lens 13 and the right focus lens. 14 is moved to that position. That is, the observer adjusts the focus once in the binocular mode and the eye fatigue recovery mode, stores the positions of the left focus lens 13 and the right focus lens 14, and uses the stored information to focus on subsequent use. It is possible to save the trouble of adjusting. That is, in the eye fatigue recovery mode, the left focus lens 13 and the right focus lens 14 are moved greatly, so that the focal position in the binocular mode is greatly changed. When switching from the eye fatigue recovery mode to the binoculars mode and trying to adjust the focus, the left focus lens 13 and the right focus lens 14 must be moved greatly, and the operation may be complicated. Accordingly, it is not necessary to perform such a complicated operation, and the operability is improved.

  When the positions of the left focus lens 13 and the right focus lens 14 are stored, it is preferable to store the date and time and user identification information together. If a plurality of data is stored, the data to be read out can be selected via the select button 4 or the like. Further, it is not determined automatically whether the positions of the left focus lens 13 and the right focus lens 14 when the focus adjustment is performed, but only when there is an instruction from the observer. Also good.

  As described above, according to the present embodiment, the position of the focus lens detected by the detection unit when performing the focus adjustment when using the binoculars and performing the eye fatigue recovery operation is stored, and the stored focus When an instruction to read the lens position is received, the position of the focus lens is read from the storage unit, and the focus lens is moved to the read position. Therefore, it is possible to provide binoculars that can recover eye fatigue and have high operability. In addition, according to the present embodiment, since the lens for adjusting the focus of the binoculars and the lens for changing the position of the image when performing the eye fatigue recovery operation are combined, the apparatus can be reduced in size.

  In this embodiment, in order to realize the eye fatigue recovery mode, the left focus lens 13 and the right focus lens 14 are moved so that the position of the image observed by the observer is in the optical axis direction of the observer's eye. Although an example of changing is shown, other configurations may be used. For example, a shift lens may be provided on the left and right in addition to the left focus lens 13 and the right focus lens 14, and this lens may be changed in the direction of convergence. At this time, the movement in the optical axis direction and the movement in the convergence direction are preferably synchronized. Further, the eye fatigue recovery operation may be performed by changing the position and size of the visual target in the images displayed on the left display unit 19 and the right display unit 20 that display images for recovery from eye fatigue. In the present embodiment, the fatigue recovery operation is realized by observing the images displayed on the left display unit 19 and the right display unit 20 via the left objective lens 11 and the right objective lens 12. The fatigue recovery operation may be realized by observing the images displayed on the left display unit 19 and the right display unit 20 through the left eyepiece lens 9 and the right eyepiece lens 10.

In this embodiment, the left and right focus lenses (the left focus lens 13 and the right focus lens 14) are moved in conjunction with each other, but may be moved separately on the left and right.
Further, as the left display unit 19 and the right display unit 20, a holder 50 and a backlight 51 containing a slide film may be used instead of a display such as a small liquid crystal display. For example, as shown in FIG. 5, the holder 50 may be detachable from the binoculars 1. With such a configuration, it is possible to save power, and the observer can perform the eye fatigue recovery operation using a favorite slide film.

  In the present embodiment, an example in which the left reflecting mirror 23 and the right reflecting mirror 24 are used to switch between the binocular mode and the fatigue recovery mode has been described. However, a half mirror is provided at the position of the left reflecting mirror 23 and the right reflecting mirror 24. In addition, the shutter may be provided outside or inside the left and right objective lenses. As another configuration, for example, a transmissive display such as EL (Electric Luminance) or transmissive liquid crystal may be provided at the positions of the left reflecting mirror 23 and the right reflecting mirror 24, and may be combined with a shutter.

  In the present embodiment, the binoculars 1 have been described. However, the present invention may be applied to a telescope including one eyepiece lens and one objective lens. In the telescope, since the observer observes with one eye, the position of the image observed by the observer may be changed only in the optical axis direction.

It is an upper surface external view of the binoculars 1 of this embodiment. It is an internal block diagram of the binoculars 1 of this embodiment. It is an internal sectional view of binoculars 1 of this embodiment. It is a control block diagram of the binoculars 1 of this embodiment. It is another internal sectional drawing of the binoculars 1 of this embodiment.
