Manufacturing method and electron for aperture mounting [Prior Art] - Generally, an aperture device for adjusting the amount of light emitted by a person in a camera optical device. In the case of an example of the configuration of the aperture device, the light amount is adjusted by the movement of the members in the right-handed/two-part. In the case of the above-mentioned optical device, it is known that the optical motor is used as a seeding light, and the electric motor is used as a squatting patent. For example, in Patent Document 2, there is a description of the driving force of the electric motor. As described above, the stepping motor is used as the pulse of the light-in stepping motor (the pulse for driving the motor, the parameter of the condition: therefore, the driving of the stepping motor is controlled by the optical shift and the sequence as a parameter) In general, the stepping motor is used for the sensor gamma. In the driving step, the county is set by using, for example, the pulse _ ^ of the input stepping motor. In this case, it is necessary to use the operation state. : 本::Feeling (4) Preparation and assembly i There is also a reading method "X", for example, referring to the example of the action peak of 疋, 3, 4).

The sub-B and the input potential state of the input dice drive the input step A to make the input terminal A twist state, so that the input terminal 2 = Urn state The input terminal B is a pulse that can be Hi-like in the shape of L〇w, and the excitation is performed by using the input B. The excitation is performed by the excitation mode corresponding to the input of the 5 Xuan pulse ^, ^$ In the second step, the input is formed so that the input terminal A is in the Hi state, the input is in the Low & state, the input terminal B is in the Hi state, and the input is made. Into the terminal B, ί-式式式冲, Xiang corresponds to the input of the pulse of the excitation type to make the stepper motor energize. In, ϊ I In the third step, the input is formed so that the input terminal L is Low state, so that 5 The pulse of the excitation mode in which the τ and & are in the H1 state, the input terminal B is in the Hi state, and the input terminal B, '', and 〇w are sinus, and the step is made by the excitation 201140229 mode corresponding to the input of the pulse. Into the motor excitation. Input ίί, f dimorph f makes the input terminal A L (four) state, b, is m makeup l, the input terminal B is L 〇 w state, so that the input terminal mode makes the step rush, fine _ _ human excitation step under the second ΐ in the state of the moving member against the stopper, between the pulse transmission, the number of input pulses in the field and the effective rotation angle of the stepping motor will produce a 3-step amplitude shift In the following, the specific thing is as follows: the actual effective rotation angle refers to the step caused by the input of the pulse. First, the premise of the description. The sequence of the pulse of the 2 motor is in the "step-up sequence" and "Step down to the secrets of the people's veins _ rail, side (four) one step for the gas: pulse At the same time, input the pulse in the order of the first step, the third step, the dj, and the subsequent cycle.

The sequence of the person's _ _ case is, for example, the following case: when the first brother is pulsed, the pulse is input in the order of the fourth step - the third step - the second step - the K is followed by the same cycle. /di brother four V When the pulse is input in descending order, the stepping motor is reversed. Moreover, in the case where the stepping motor is reversed, the direction of the shaft member _ near the age of the stepping step is positively input when the pulse is stepped, the stepping motor rotates forward, and when the motive is rotating forward, the moving member Move away from the direction of the stop age ^,, and, in other preconditions, when moving from the moving parts to the third step of the industry, a) the fourth step one > the first step pulse '< When inputting the stepping motor, 'according to the above-mentioned excitation mode (the same cycle is performed later); t In this case, the stepping motor accompanying the input of the pulse is based on the start of the rotation (the moving member abuts The angular position of the rotation direction of the 201140229 machine differs depending on the state of the carrier. The following is divided into four examples. (1) First example When the moving member abuts against the stopper, the stepping motor stops at Corresponding to the angle of the excitation mode of the first step described above, the stepping motor rotates the i-step amplitude when starting the second input. The abundance 'in the order of the third step - the fourth step - the first step When inputting a pulse, the stepper motor responds This is gradually rotated. #Result'In the state of the moving member against the stopper, in total, 4 pulses are input into the stepping motor in the order of the second step to the third step. The stepping motor is rotated by 4 steps in total. The ^ of the money (2) The second case is in the state of the moving piece, and the stepping electric age is stopped at the angle of the corresponding pulse mode. In the case, even if the second input is started, the stepping motor stops and does not rotate because the V input motor originally stops at the angle corresponding to the excitation mode of the second step. Three steps - the fourth step - the first step of the sequence when the pulse is input, the motor is gradually rotated according to this. The state of the carrier is stepped in the third step, the second step, the electric motor is stepped; The step of the stepping motor (3) The third case " in the upper case and the stepping motor stops at the corresponding = pulse 'stepping motor; the traveling machine stops without rotating. (4) It is also blocked by the social pull. Therefore, stepping Electric in the S is also due to the stepping motor originally stopped. Therefore, the stepping motor stops and does not rotate. When the pulse is rounded in the order of the fourth step, the stepping motor 201140229 is rotated according to this step. Step-fourth step according to the second step 5 third stage two = motivation total rotation _ = the fourth step of the stepping motor stops at the corresponding rush, according to the stepping motor, the start input of the second step of the pulse into the three movements The difference is that the step starts to input the angular position of the pulse excitation mode of the second step and the motor exceeds the second step corresponding to the first step, when according to the third step "second again: the stepping motor is adapted to Therefore, when the order of the step-by-step rotation of the plant 4 is stepwise, in the segment, the stepping motor totals s pulses to input the step of the stepping motor (4b), and the second action mode is Putian again. (When the pulse of the first step is input, the angular position of the excitation mode of the bull's life and the returning motor are intended to exceed the third step. But the angle of the excitation mode of the stepping motor is stopped without rotating ^ The lifting block is blocked. Therefore, the stepping motor is second, when the pulse of the third step is input, the angular position corresponding to the excitation mode of the step is reversed: the motor is intended to return to the third element H. Therefore, the step When the motor is stopped, the rotation of the motor is stopped, and even if the input of the fourth step is in the excitation mode corresponding to the fourth step, the stepping motor is stopped and does not rotate. Therefore, the stepping motor is stopped. As a result, the stepping motor is rotated by 1 step amplitude - the state of the minus piece is in accordance with the second step - the third step 201140229 paragraph Ϊ ί; ΐ :: input with miscellaneous The third action mode of the stepping motor (4c) is Tian (the magnetic force acting on the rotor of the stepping motor is three steps of magnetic 32; the pulse stepping motor is required to return corresponding to the first piece to block. Therefore, the face is stopped. In the right = the first ===rw_ machine will stop turning * Shoulder-type purchase angle, so the stepper motor stops without rotating, when the first step pulse is input, the step f motor rotates and the step is produced. Step; II iji depends on the stopper In the state according to the second step 4 three-stage, 4-input pulse input stepping motor: pulse between the moving part against the stopper butterfly ^ organic condition 'pulse input quantity and stepping electric - interesting angle between the maximum The offset of the three-step amplitude is generated. The driving source for reading the rotation angle of the stepping motor of the motive causes the moving member to move, and causes the following motor to be the state when the moving member abuts against the stopper. When a number of two motors are to be specified, the stepping electric & second drama eight based on the pulse input is finally stopped, and the main purpose of the largest meeting is to provide a structure to go); (4) The age-type driving step The first aspect of the invention relates to an aperture skirt, the aperture skirting package 201140229 includes ., ίif forms an opening for light to pass through; the action member causes the light to illuminate the opening, Direction of change in opening diameter Movement: limiting the movement range of the unit to say that the movement mechanism is assembled to: when the restriction of the soap element is used to restrict the rotation of the rotation direction: the above-mentioned opening portion is formed, and the light emitted by the person is converted into an electrical signal. μ - (4) ring member 2 of the above stepping motor: 2, 5, _ for a camera 'The camera comprises: the above-mentioned photoelectric conversion element, which will pass through the third aspect of the invention Difficult manufacturing method, the above light

Drive method of device 1 ( Description of the matter First, in the embodiment of the present invention, as described above, the stepping motor 8 is utilized, and the first step, the second step, the third step, and the r are used. The step (excitation mode) drives the stepping motor 8T to specifically drive the stepping motor 8 in the excitation mode corresponding to the four steps. In this case, the "phase drive" is taken as an example. ϋ, in the first step In the input, the input terminal A is in the state, the input terminal is #; the sorrow is made, the input terminal B is in the L〇W state, and the input terminal B is made to be pulsed (four) in the excitation mode of the input of the pulse. Into the motor excitation. Into the second step towel 'input shape button terminal A is Hi state, to make the transition state W state, the input terminal B is Hi state, the input terminal B, the pulse mode of the excitation mode is utilized The oscillating input of the pulse yoke enters the motor excitation. In the three steps, the input is formed such that the input terminal Α is in the L (four) state, the ^ Low H1 state is made, the input terminal B is twisted, and the input terminal B is made. Mode makes stepping \ pulse, shed against _Input excitation input ΐ Π吏 Input terminal A is in the L (10) state, so that the mode makes the pulse, _ corresponds to the excitation of the pulse_ input, and the motor is less energized. When the servo is entered into the machine 8, the armor The driving circuit 72 advances the stepping motor movement f8 according to the predetermined step. The case where the pulse driving step is the first: the input f is rushed from the motor driving circuit 72, for example, the following case: when the second step t is taken to the second step The fourth step, as a cycle of one cycle, in the order of the cycle, the third step, the fourth step, the fourth step, one step later, the same refers to the following situation ^. And the case of the 'M miscellaneous person's pulse is for example 丨The number of steps of the week is four to four steps: the same cycle) the order ^i step - the first step to descend: ?,; pulse, the stepper motor 8 forward, the motor 8 Positive "=, brother 0J machine 8 reversed. And, in the step (4) fWF, the tilting member 15 is rotated counterclockwise in a plan view, 27 20 Π 40229, and the diaphragm blades 5 and the cymbal are moved toward the contraction tamping. Further, in the stepping motor, a few turns 8 = a direction in which the aperture diameter is reduced, and a clockwise * direction is rotated, and when the motion n is made, the operating member 15 moves in a direction in which the aperture diameter increases. The solid webs 5, 6 are oriented in the direction in which the aperture is opened (so that the stepping motor 8 is positively ft!! from the phantom state (restricted state) of the operating member 15; The direction of 4B is rotated, and the state in which the H member 15 is moved away from the hanging portion toward the hook portion 43B causes the hook portion 4 of the stepping electric member 15 to be reversed when the hook portion 4 is reversed toward the stopper portion 4B, and the action member 15 is turned toward the hook. The rotation is "forward rotation" or "reverse rotation; = about the stepping motor 8 rotation direction as "forward rotation", "reverse rotation"" is the concept in the book, which is the hook of the hinge member When the 43B magnetic mode is stepped up and the pulse is pressed into ^^^, the angle of the white pavilion according to the above-mentioned illustration is determined as follows: when the motor 8 is excited by the above-mentioned motor 8, the angle of the pavilion is produced again. ^Using the excitation mode of the step to make the three-step stop angle of the excitation mode in the third step as the step stop "i", the step stop angle when the excitation is excited, "the fourth step is to stop the paste (four) the excitation mode to make the step When the remaining machine 8 is excited (description of the driving method), the driving diagram of the diaphragm device 1 according to the embodiment of the present invention The driving method shown in the figure is executed by the control unit 7〇. No, at least p, ^, please enter the lamp. Yes, the initial setting is required, and the operation performed in steps S2 and S3 will be described later. "Initial setting action" is judged.

The direction of the limit is driven by the stepping motor = except for the load-bearing portion 4B ^ receiving the control motor from the motor: ί 2 two-circuit circuit port MB. In this case, the input start pulse is used, for example, by the use of the armpit, that is, the stop of the movement of the aperture device, the movement of the diaphragm unit 5, and the movement of the diaphragm blades 5 and 6 Part 4B Limit - Step stop The step from the next step is set to the first round of the start pulse ί. , ^, with '~, the pulse of the excitation mode in the second step and 'in the state where the stop portion 4 is used to 丨 φ _ very μ: the end of the step stop angle paste 5, = should be Lose.3. In the case where the movement range of the i-state T-stops 5, 6 is in the step of the excitation mode, the pulse having the step-stop angle set as the fourth step = degree is used as the input start pulse. In the third driving period, the signal 3 is sprinkled. In the manner of the number of control commands, the step-up sequence of the stepping current, the descending order, and the driving of the stepping motor 8 in the second driving period are continuous. Then, the transition rectification step is stopped temporarily, 30 201140229 in the second driving period, the value of the electric aperture, and the control command signal: 1 circuit 71 receives the 'motor driving circuit 72 according to the target aperture motor driving circuit 72. .

When the stepping motor 8 is used, the count value of the number of input pulses and the value of the aperture diameter are 1:1::2, if the experiment is taken in advance, the corresponding _ of the two is grasped, and according to each / material (such as table surface, computing program _ incorporation = whole in In the third driving period, the light and the aperture can be adjusted by the pre-administration control. The following is specifically described. Although the target value of the aperture aperture to be specified by the control command signal is set to =, the control circuit 71 controls from the above. The target data of the number of input pulses of the aperture σ path is read by the data used, and the specified value is generated by the value of the number of pulses and the target value of the number of input pulses "D1" - 31 201140229 And the number of control command signals are output to the motor drive circuit 72. Thus, the machine drive circuit 72 uses the number of pulses specified by the control command signal to illuminate the sequence (upward or descending order) specified by the command signal. For example, the target value "D1" with respect to the number of input pulses is equivalent to the input of the stepping motor 8 in descending order in the case where the count value of the number of rounded pulses is greater than D1 "Da". The pulse of the number of the difference "Da-Dl". Conversely, with respect to the target value "D1" of the number of input pulses, when the count value of the number of input pulses is smaller than DD / Db", In the step-up sequence, a pulse corresponding to the difference "D1_Db" is input to the stepping motor 8. Then, in the case where the target value &amp; "D1" of the input pulse number is switched to, the count value and the value of the thief, the gambling thief are responded to. The pulse of the field thief is input to the stepping motor 8 in such a manner that the pulse value is equal to the target value. <Equation of the present embodiment> The following describes the effect of the present invention. In the case where the diaphragm device is driven by the above-described driving method, the input is started when the hook portion 43B of the member 15 abuts against the stop portion 4B (restricted state). When the pulse is input to the stepping motor 8, the stepping operation is performed in response to the input of the pulse. Red, the rotation operation of the stepping motor 8 can be obtained for all of the aperture devices 1 to which the second embodiment of the present invention is applied. ^ Therefore, in the case of the limit g, each of the determined number of pulses (10) of the aperture device 1 is stepped in all the light sets by one step by the same amount of rotation. Therefore, in the case where the stepping motor 8 is driven by the same number and order from the restricted state, the stop position of the diaphragm blade 〜 does not cause an offset (deviation). Therefore, when the motor 8 is used, it is possible to prevent the position of the diaphragm 5 blades 5 and Ο from being shifted. As a result, in the case where the stepping motor 8 is used as the m-iris device 1, the accuracy of the aperture adjustment can be improved without using a sensor or the like. 32 201140229 The aperture mount if circle used in the method is the same as the opening π diameter of the third embodiment. According to the aperture of the aperture member, it is expected that the high precision of the aperture lamp is set to the next step in the ascending order corresponding to the pulse input. The excitation mode) corresponds to the pulse. Therefore, when the T ^ degree (the next step relative to the input of the pulse and no action, and the phase of the phase _ 敝 敝 的 的 参考 Σ tt tt tt tt tt tt ( ( ( ( ( ( ( ( ( ( ( ( When the white end is adjusted, the stepping motor stops at the end corresponding to the ift = the end of the pulse input stepping electric = 圏 = the stop is called "the initial stop angle r : ΐ : ί ^ after the same The sequence of the input pulse is input in the order of the cycle.
