The relationship is to do. Therefore,
In the following description, AF is described as diopter adjustment, and the description of AF is omitted.

Is a window for viewing the IC card.

The bottom view of FIG. 3 and the rear view of FIG. 4 show a light emitting portion 8 and a light receiving portion 9 which emit light for detecting that the user is looking into the binoculars 1. This is because, as will be described later, when the user's nose enters the recess 10 of the binoculars, the light from the light emitting section 8 is blocked and does not reach the light receiving section 9, making use of the user. To detect use,
As a result, the diopter adjustment and the interpupillary adjustment are started.

The switch 32 is a display ON / OFF switch driven by operating the display ON / OFF button 3 shown in FIG. A display control CPU 36 receives data from a memory 37 (in this case, an IC card) that stores constellation data and the like, and a GPS circuit 34, performs arithmetic processing on these data, and outputs the data in a dot matrix type. And the time (the time measured by the CPU 36 itself) is displayed on the display unit 38 configured as described above. At this time, the EL backlight 39 is turned on via the EL drive circuit 40 for the backlight because the display unit 38 is composed of a liquid crystal display element (LCD) in this embodiment.

The right diopter (focus) adjusting CPU 41 drives and controls the CCD line sensor 42 in the diopter detecting device 22, receives information from the CCD line sensor 42 and sends it to the main CPU 30, and at the same time, the motor. Driving the right diopter adjusting motor 24 via the driver circuit 43. The left diopter (focus) adjusting CPU 44 functions substantially in the same way as the right diopter (focus) adjusting CPU 41 except that it is related to the left diopter adjusting.

In FIG. 15, 103 and 104 are eyepiece hoods made of a soft rubber material.
Reference numerals 5 and 106 are protective glasses.

In this embodiment, the GPS circuit 34 uses the GPS
It is a circuit provided for knowing the current position of the binoculars by using. GPS is a radio navigation system using a plurality of artificial satellites, and it is possible to obtain three-dimensional position information of a GPS receiver extremely accurately. Each satellite transmits a microwave satellite signal modulated by pseudo random noise (hereinafter referred to as "PN code"). Since each satellite uses a different PN code, a GPS receiver generates a PN code corresponding to a specific satellite and the correlation with the received code is transmitted from the specific satellite. Signal can be selectively received.

The configuration of the GPS receiver used in the binoculars of this embodiment will be described below with reference to FIG. This GPS receiver is composed of components shown by reference numerals 51 to 61. Reference numeral 51 is an antenna for receiving satellite signals from each artificial satellite (not shown). The RF (radio frequency) signal input to the antenna 51 is input to the mixer 52. On the other hand, the local oscillation signal CK1 generated by the local oscillator 53 is transmitted to the modulator 54
Through the PN code output of the PN code generator 55 and then input to the mixer 52. This makes RF
The signal is converted into an IF (intermediate frequency) signal and input to the data demodulation circuit 56. The data demodulation circuit 56 demodulates the data including the signal transmission time of the satellite from the input signal, and this demodulation data is input to the data processing circuit 57 and the delay measuring circuit 58.

When the delay measuring circuit 58 receives the demodulation data, it first sends a timing signal to the PN code generator 55. The PN code generator 55 constantly generates a PN code by the clock output CK2 of the PN code clock generator 59. When the timing signal is input, the generated PN code is measured with a delay. It is designed to be sent to the circuit 58. The delay measuring circuit 58 measures the delay time of the PN code when the correlation between the received PN code and the PN code from the PN code generator 55 is obtained. This delay time is obtained by counting the highly stable clock CK3 generated by the counting clock generator 60, and the counted value is calculated by the PN
The time data required for the correlation of the data, that is, the delay data is output. This delay data is the data processing circuit 5
Sent to 7.

The data processing circuit 57 comprises a microprocessor and is driven by the clock CK4 from the data processing clock generator 61. Then, the radio wave propagation time from the satellite to the positioning device is obtained from the transmission time data and the reception time data in the demodulation data, and the distance from the satellite to the positioning device is detected by this. This distance information and the position information of the satellite itself in the demodulation data are acquired for each satellite,
The position information (longitude, latitude, altitude) of the positioner is calculated from each acquired data, and the calculation result is output to the display CPU 36.

The display CPU 36 has a clocking function, performs arithmetic processing based on the clocked time, the coordinate data of the stars fetched from the memory 37 and the position information from the GPS circuit, and at that time. The state of each constellation visible from the position is displayed on the display unit 2. At this time, time and position information are also displayed at the same time. 19 to 21 show examples of the display, in which the date is shown in the upper left corner of the display unit 2, the time is in the upper right corner, the current position is in the lower right corner, and the altitude (above sea level) is in the lower left corner. Here, NL represents north latitude, EL represents east longitude, and WL represents west longitude.

Next, FIG. 11 shows a schematic diagram of the diopter detection device 21 and the pupil distance detection device 19 incorporated in the eyepiece part of the left optical system of the binoculars 1. The light emitted from the light source 70 is condensed on the slit 72 by the elliptical mirror 71, and the slit 7
After passing through the half mirror 73 from 2, the half mirror 1
7 and go through the eyepiece lens 15 from left to right,
On the other hand, the light is projected from the eyepiece lens 15 substantially in parallel. Eyeball 7
The slit 72 for projecting 5 is at a position optically equal to the image plane 76 of the objective lens of the binoculars 1.

A light projecting portion comprising a light source 70, an elliptical reflection mirror 71, and a slit 72 is common to the diopter detecting device 21 and the pupil distance detecting device 19, and of the light hitting the eyeball 75, the light entering the pupil 77 is the diopter. It is used by the detection device 21 for diopter detection. Pupil 7
The light entering 7 is projected on the retina 78 by the refractive power of the eye. This light is reflected by the retina 78 and travels in the opposite direction along the incident optical path, is reflected by the half mirror 17 and the half mirror 73, and forms an image near the diaphragm 79.

The diaphragm 79 cuts off stray light reflected by the cornea other than the above light and has a width wider than that of the slit 72. A re-imaging lens 80 is arranged further downstream, and the light passing through the re-imaging lens 80 is split into two optical paths by the split prism 81 and reaches the CCD line sensor 45. CCD
The image on the line sensor 45 is located at different positions in the two optical paths when viewed optically. The one reflected on the left side of the drawing is located far from the image point of the re-imaging lens 80, and the one on the right side is located near. ..

The light projected and reflected on the retina 78 forms an image near the diaphragm 79 through the eye refractive power and the eyepiece lens 15. This image forming position is at a predetermined position if the diopter is matched with the image plane of the objective lens due to the refractive power of the eye, and the image forming position is displaced due to the deviation of the diopter. As a result, the spread of the two light fluxes reaching the CCD line sensor 45 changes.
By comparing the intensity distributions of the two light fluxes on the CCD line sensor, it can be seen whether or not the diopter is matched, and which is deviated. By moving the eyepiece lenses 15 and 16 in the optical axis direction, the diopter is determined. Can be matched. Since the diopter detection device of this embodiment is basically the same as the contrast method in AF of the camera, for example, Japanese Patent Publication No. 63-442.
A circuit such as No. 05 may be used.

The diopter may be detected by a phase difference method instead of the contrast method. in this case,
The configuration of 45, 79, 80, 81 in FIG. 11 may be replaced with that in FIG. FIG. 21 is a diagram showing another embodiment of the optical system of the diopter detection device. The alternate long and short dash line Z indicates the optical axis of the eyepiece lens 15, and the dotted line F indicates the planned focal positions of the eyepiece lens 15 and the eye 75. The condenser lens LC is arranged at a position slightly behind the planned focus position F. Condenser lens L
Behind C, the imaging lenses L1 and L with the optical axis Z as the axis of symmetry
2 is arranged, and a mask plate MK having openings A1 and A2 is provided in front of the imaging lenses L1 and L2. C near the image plane of each of the imaging lenses L1 and L2
A line sensor 45 composed of a CD is arranged. The images If, Io, and Ib on the optical axis are the eyepieces 1 respectively.
5 shows the images in the front focus, in-focus and rear focus states for the image on the anterior retina of FIG. The re-formed images I1o and I2o of the focused image Io are formed at positions substantially coincident with the line sensor-45, and the re-formed images I1f and I2f of the front-focus image If are focused re-formed images I1o and I2o, respectively. A re-formed image I1 of the image Ib of the rear focus, which is formed at a position in front of I2o and close to the optical axis Z.
b and I2b are formed at positions behind the focused re-formed images I1o and I2o and away from the optical axis Z. Line sensor
The amount of focus deviation is detected by 45 depending on whether the distance between the two re-formed images is longer or shorter than the distance between the two re-formed images at the time of focusing.

The diopter detection by the phase difference method and the contrast method as described above have the following advantages and disadvantages, respectively. The pupil diameter changes depending on the brightness of the visual field. In the phase difference method, since the luminous flux used for detection is constant, the accuracy of diopter detection can be kept constant even if the pupil diameter changes depending on the brightness of the visual field. However, if it is very bright, the pupil may become too small and the light flux for detection may be vignetting, and at this time diopter detection becomes impossible. If a light flux that is as close to the center of the pupil as possible is used to eliminate vignetting, the detection accuracy will deteriorate.
Further, when the pupil position deviates slightly from the eyepiece optical axis, vignetting occurs in only one light beam, and diopter detection is also impossible.

In the contrast method, the accuracy changes depending on the pupil diameter, but it is unlikely that diopter detection cannot be completely disabled due to vignetting such as a phase difference. However, when the field of view becomes dark and the pupil diameter increases, the detection accuracy increases, and conversely, when it becomes bright and the pupil diameter decreases, the detection accuracy decreases. Further, the diopter shift amount with respect to the output of the detection unit changes depending on the pupil diameter. With this, the amount of movement of the eyepiece lens is not uniquely determined by the output of the detection unit.
This can be corrected by the following method. Not shown. Another light receiving element is provided to measure the brightness of the visual field. If this is AF binoculars, it may also serve as a sensor for AF. The pupil diameter may be assumed based on the brightness of the visual field, and the coefficient of the amount of movement of the eyepiece lens with respect to the output of the detection unit may be changed accordingly.

Next, the light receiving portion of the pupil distance detecting device will be described. This detects the shift between the eyepiece optical axis and the pupil position using the principle of detecting the eye movement. The embodiment utilizes a detection system for the left and right pupil positions. The light hitting the pupil from the light projecting portion passes through the pupil position detection lenses 82 and 84, and is received by the SPCs 83 and 85. These are arranged so as to gaze near the boundary between the black eye and the white eye in the horizontal plane including the optical axis with the pupil position aligned with the optical axis.

If the pupil is displaced to the R side, for example, SPC8
In the glare area of 3, since the proportion of black eyes is increased and the projected light absorbs a large amount by the eye and the reflected amount decreases, the SPC8
The output of No. 3 is small, while the SPC 85 has a large proportion of the white eyes in the gaze portion, so the output is large. Therefore, if the difference (VL-VR) between the output VL of the SPC 85 and the output VR of the SPC 83 is taken, the output becomes positive. Conversely, if the pupil is shifted to the L side, the output will be negative. Interpupillary distance detection is performed based on the outputs of these SPCs 83 and 85. FIG. 12 shows a circuit block of the pupil distance detecting device.

Although FIG. 11 described above shows only the left eye, a similar pupil distance detecting device is provided for the right eye. In FIG. 12, the SPC 8 of the interpupillary distance detection device for the right eye
6, 87 are also shown. In FIG. 12, the SP of the left eye
The differential amplifier 88 takes the output difference of C83 and 85, and the differential amplifier 89 takes the difference of the outputs of the right-side SPCs 86 and 87.
These differences are taken as linearity correction devices 90 and 9 respectively.
Through 1, the left and right eye misalignment amounts are obtained. Next, the difference between the outputs of the left eye and the right eye (left eye-right eye) is taken by the differential amplifier 92. When this value is 0, that is, when the shift amount of the left eye is the same as the shift amount of the right eye as shown in FIG. 13, the interpupillary distances match, so the interpupillary movement device 9 including the motor 25.
3 does not work.

However, if the output value of the differential amplifier 92 is positive, it means that the optical axis interval of the binoculars is wider than the pupil interval of the right eye and the left eye as shown in FIG. Lens barrel 11, 1 so that the optical axis interval is narrowed by
2 (eyepieces 15 and 16) is moved. On the contrary, if the output value of the differential amplifier 92 is negative, the optical axis interval of the binoculars is narrowed, and therefore the lens barrels 11 and 12 are moved so as to widen them.

In this embodiment, the lens barrels 11 and 12 are common to the objective lenses 13 and 14 and the eyepieces 15 and 16, respectively. However, the objective lens barrel and the eyepiece lens barrel are formed separately. It is also possible to move only the lens barrel of the eyepiece when adjusting the interpupillary distance. In this embodiment, the binoculars do not move the optical axes of the right eye and the left eye individually so that the amount of pupil misalignment becomes zero, and move only the optical axis interval after taking the difference between the right eye and the left eye. The subtle movements of the whole eye and the eyes, or when the field of view deviates from the center of the field of view temporarily,
This is because the same amount of pupil misalignment occurs in the same direction for both left eyes, and the type of moving individually causes frequent movements and is troublesome. In this respect, the present embodiment does not move with respect to such a temporary thing. Further, since no moving device is required individually, it can be achieved at low cost.

In this embodiment, as described above, the diopter detecting device and the pupil distance detecting device can be used in common, so that compactness and low cost can be achieved. If a near-infrared LED or the like is used as the light source, a hot mirror or a dichroic mirror can be used as the half mirror, and the brightness of the visual field will not be darkened. In addition, even if the light is projected, it is invisible.

Next, the flow chart will be described. In the main flow shown in FIG. 16, when the main flow starts, the main CPU 30 first resets the ED flag indicating that the interpupillary distance adjustment has been completed in step # 5. Subsequently, in step # 10, the light emitting element 47 (FIG. 9) is momentarily turned on, and then in step # 15, it is determined whether or not a detection signal is output from the detection circuit 49. If the detection signal is output, it means that the user is looking into the binoculars 1. Therefore, the process proceeds to step # 20 and the display unit 2
Is turned off. This is because the display unit 2 cannot be seen when looking through the binoculars 1, and it is useless to set the display unit 2 in the display state. For the same reason, the GPS circuit 34 is also turned off (step # 2).
5).

Next, at step # 30, the light source 70 which emits light to the eyes is turned on. And step # 3
In step 5, it is determined whether or not the ED flag is set. If it is set, the process directly proceeds to step # 50, but if it is not set, the eye width adjustment subroutine is executed in step # 40, and the ED is set in step # 45. Step # 5 after setting flags
Go to 0. Here, the ED flag is set because it is only necessary to adjust the pupil distance once as long as the binoculars are continuously used (the detection signal is output in step # 15).
Step # 50 performs binocular diopter adjustment, and when this is done,
Return to step # 10.

When the detection signal is not output in the determination of step # 15, the process proceeds to step # 55 to turn off the light source. This is to remove the nose from the binoculars 1 (hence the eyes) and to stop looking into it. Therefore, the light source is turned off in order to prevent unnecessary battery consumption.
And After turning off the light source, the ED flag is reset in step # 60. That is, this is to ensure that the interpupillary distance adjustment is performed when the eyes are once removed and they are not used and then they are used again. Next, in step # 65, it is determined whether the display switch is ON. If the display switch is OFF, the display of the display unit 2 is turned OFF in step # 90, and the GPS circuit 34 is turned off.
After setting to FF (step # 95), the process returns to step # 10.

If the display switch is ON in the determination in step # 65, it is determined in the next step # 70 whether the IC card is mounted. Here, if the IC card is attached, the display of the display unit 2 is turned on and the GPS circuit 34 is also turned on (steps # 75, 8).
0) and then execute the card function (step # 8).
5) Return to step # 10. If the IC card is not mounted in the determination in step # 70, the process returns to step # 10 through steps # 90 and 95.

FIG. 17 shows a subroutine for the interpupillary distance adjustment in step # 40 of FIG. 16. When entering this routine, first in step # 100, it is judged whether the left and right pupil deviation amounts are the same. If they are the same, it means that the interpupillary distance is correct. Therefore, the process proceeds to step # 135 and returns. If they are not the same, it is determined in the next step # 105 whether or not the shift amount of the left eye is larger than the shift amount of the right eye. If the shift amount of the left eye is large, the eye width adjustment mode is moved in the direction of narrowing the pupil distance. The motor (M3 motor) 25 is driven, and this is repeated until the left and right eye displacement amounts are the same (step # 11).
0, # 115). If the left and right eyes are displaced in the same amount, the motor is stopped in step # 130, and then the rotation is repeated.

When the shift amount of the left eye is equal to or smaller than the shift amount of the right eye in step # 120, the motor is driven in the direction of widening the pupil width, and this is repeated until the shift amounts of the left and right eyes become the same ( Steps # 120, # 125). When the amounts of deviation are the same, the motor is stopped in step # 130, and then the routine returns.
