(Shown), an endoscope tube (not shown), and an elastic member (not shown). Specifically, the body has a front end portion and a rear end portion, the objective lens unit is connected to the front end portion, and the eyepiece unit is connected to the rear end portion. The inner lens barrel is disposed inside the body, is located between the objective lens unit and the eyepiece unit, and includes a plurality of lenses (not shown).

The compensation device 100 is disposed on the body, extends through the body to abut the inner lens barrel, and adjusts the optical axis. The compensation device 100 may be a height compensation device or a wind deviation compensation device. The height compensation device is usually disposed above the body, and the wind deviation compensation device is usually disposed on the left or right side of the body.

As shown in FIG. 1, the compensation device 100 includes an adjustment cover 10, a conversion unit 12, an adjustment unit 14, a display unit 50 (see FIG. 3), a processing unit 40 (see FIG. 3), and One base 16. Wherein, turning the adjustment cover 10 will drive the adjustment unit 14 to rotate and move. The conversion unit 12 converts the displacement of the adjustment unit 14 into an electrical signal and outputs the electrical signal. The processing unit 40 determines the rotation circle of the adjustment cover 10 based on the electrical signal. The display unit 50 can display the number of rotations for the user to view. The assembly of these components is described in detail below: The base 16 is disposed on the body of the sight and has an adjustment hole 161, wherein the adjustment hole 161 has an internal thread (not shown). The adjusting unit 14 is disposed on the base 16 and can extend and axially pass through the adjusting hole 161 to reach the inside of the body, and the adjusting cover 10 is connected to the adjusting unit 14. Specifically, the adjustment unit 14 includes a transmission member 141 and an adjustment screw. 143, and the transmission member 141 is disposed on the base 16 and has an accommodation space 411 and a central hole 413. The adjusting screw 143 is disposed in the central hole 41 and has a first end 431, a second end 433, and an external thread (not shown). The first end 431 extends through the adjusting hole 131 and reaches the inside of the body. Abutting on the inner lens barrel, the second end 433 extends into the accommodating space 411, and the external thread is used to cooperate with the internal thread of the adjusting hole 161.

The conversion unit 12 is disposed in the accommodation space 411 and includes a first resistor 121, a circuit board 123, a socket 125, a coil 127, a wire 129, and a sleeve 131. Specifically, the sleeve 131 is disposed in the accommodating space 411, and the first resistor 121 is fixed to an inner peripheral surface of the sleeve 131. It can be understood that even if the sleeve 131 is absent, the first resistor 121 can be directly fixed in the accommodating space 411. The socket 125 is disposed on the second end 433 of the adjusting screw 143, the circuit board 123 is fixed to the socket 125 by the screw 201, and the coil 127 is fixed to the circuit board 123 by soldering, and can contact the first resistor 121 . One end of the lead wire 129 is fixed to the first resistor 121 by soldering, and the other end is also fixed to the circuit board 123 by soldering.

It should be noted that the first resistor 121 is a variable resistor, and the circuit board 123 includes a second resistor 203 (see FIG. 2). Referring to FIG. 2, after the first resistor 121, the circuit board 123, the coil 127 and the lead wire 129 are assembled as described above, a voltage dividing circuit 20 will be formed. Specifically, the second resistor 203 is connected in series with the first resistor 121 and is connected to an input voltage V _in , and the first resistor 121 is grounded. Furthermore, an output voltage V _out (that is, the electrical signal) is output from a connection node between the first resistor 121 and the second resistor 203. Among them, the output voltage V _out can be expressed by the following equation (1): V _out = V _in × R ₁₂₁ / (R ₁₂₁ + R ₂₀₃ ) ... (1)

Among them, R ₁₂₁ is the resistance value of the first resistor 121, and R ₂₀₃ is the resistance value of the second resistor 203. In this embodiment, the input voltage V _in is approximately 1.8 ± 5% volts (V), that is, approximately 1.71 to 1.89 volts (V). The resistance value R _{121 of the} first resistor 121 is approximately between 0K and 118.8K ohms (Ohm, Ω), and the resistance value R _{203 of the} second resistor 203 is approximately 22K ± 1% ohms (Ohm, Ω), that is, It is approximately 21.78K ~ 22.22K ohm (Ohm, Ω). In other words, after calculation of equation (1), it can be known that the output voltage V _out is approximately between 0 and 1.5972 volts (V).

When the compensation device 100 is operated to perform spring compensation, the ring-shaped rotation adjustment cover 10 will drive the adjustment unit 14 to rotate relative to the base 16, and further cause the adjustment screw 143 to move up and down relative to the base 16 along the axial direction. At the same time, the circuit board 123 indirectly carried on the adjusting screw 143 also moves up and down along the axial direction, thereby changing the contact position of the coil 127 and the first resistor 121. After the contact position of the coil 127 and the first resistor 121 is changed, the resistance value R _{121 of the} first resistor ₁₂₁ also changes between 0 and 118.8K ohms (Ohm, Ω), and the scoring circuit 20 is changed. The output voltage V _out changes.

Referring to FIG. 3, the output voltage V _out is converted into a conversion value V _C by an analog-to-digital converter (A / D converter) 30. Among them, the conversion value V _C can be expressed by the following equation (2): V _C = V _out × 2 ⁿ / V _Ref … (2)

Wherein, n is the resolution of the analog-to-digital converter 30, and V _Ref is the reference voltage of the analog-to-digital converter 30. Assume that the resolution n is 10 and the reference voltage V _Ref is approximately 1.5 ± 5% volts (V), that is, approximately 1.425 to 1.575 volts (V). The analog-to-digital converter 30 uses the equation (2) to output the voltage V _{Out is} converted into a converted value V _C and transmitted to the processing unit 40. After several conversions, a correspondence table of the output voltage V _out , the conversion value V _C and the number of rotations can be obtained (see Table 1). As can be seen from Table 1, Table 1 is a comparison table that records a plurality of rotations and the corresponding analog-to-digital converter output value V _C and can be stored in the processing unit 40. The processing unit 40 receives the conversion value V _C Then, the number of rotations of the compensation device 100 (that is, the number of rotations of the ring in the adjustment direction of the cover 10 or the axial movement distance of the adjustment screw 143 can be determined by looking up a table or the like according to the magnitude of the conversion value V _C (that is, the output voltage V _out ). ), And control the display unit 50 to display the number of rotations. Wherein, when the conversion value V _C received by the processing unit 40 cannot correspond to a preset value range on the lookup table, the processing unit 40 may use interpolation to determine the number of rotations of the compensation device 100.

In another embodiment, in order to prevent the processing unit 40 from generating an error during the judgment, the resistance value R _{121 of the} first resistor 121 corresponding to the number of rotations of the adjustment cover 10 may be selectively set, where the number of adjacent rotations is setting the resistance value R ₁₂₁ is non-continuous value, for example, assumed that the resistance of the first resistance adjustment 121 at the time of the second ring 10 is rotated to cover the value of R ₁₂₁ ohms to 0.1K ± 20% (ohm, Ω), That is, approximately 0.08K to 0.12K ohm (Ohm, Ω), and the resistance value R _{121 of} the first resistor 121 when the adjustment cover 10 is rotated to the third turn is set to 1K ± 20% ohm (Ohm, Ω), That is, approximately 0.8K ~ 1.2K ohms (Ohm, Ω), because the resistance value R ₁₂₁ of the first resistor 121 when the cover 10 is rotated to the second turn is the same as that of the first resistor 121 when the cover 10 is rotated to the third. There is no overlap in the range of the resistance value R ₁₂₁ during the turn. After calculation, the output voltage V _out does not overlap when the adjustment cover 10 is rotated to different turns, so the possibility of misjudgment of the processing unit 40 can be reduced.

Among them, the so-called axial direction refers to the displacement direction of the adjustment screw 143 of the adjustment unit 14 driven by the adjustment cover 10, and the axial direction is also the direction in which the adjustment screw 143 pushes against the endoscope barrel; and the circumferential direction refers to the rotation. Act.

Generally, when the compensation device is not powered on, if the adjustment cover is turned by mistake for more than one turn, even if the compensation device is powered on again, the user cannot detect the change in the number of rotations. It is worth noting that the compensation device 100 of the present invention utilizes the axial variation of the adjustment screw 143 to avoid a blind spot that generally only adjusts the variation in the hoop (angle) of the cover 10. In this embodiment, when the compensation device 100 is not powered on (that is, when the input voltage V _in is 0), although the processing unit 40 cannot determine the number of rotations of the compensation device 100, the rotation of the adjustment cover 10 will still change the coil 127 and the first An axial contact position of the resistor 121. Therefore, after the compensation device 100 is powered on again, the conversion unit 12 can still generate the output voltage V _out again according to the resistance values of the first resistor 121 and the second resistor 203, and the processing unit 40 still judges the compensation according to the magnitude of the output voltage V _out . Number of rotations of the device 100. In other words, even if the user accidentally touches the adjustment cover 10 when the compensation device 100 is not powered on, the rotation number of the adjustment cover 10 can be displayed after the compensation device 100 is powered on again. For the user, It will be more intuitive and convenient.
