The reduction gear shown in Figures 3 and 4A and more specifically in Figure 4B includes a plurality of gears 7, 9 and 11 that mesh with each other. The gear 7 meshes with the motor gear 3 of the power supply 1, and the gear 11 meshes with a The focus control ring 13 connected to the focus control lens is engaged. The reduction gear is located on a shutter base (S) and connected to the lower part of the motor base (B). As shown in FIG. 5, a spiral (H) is formed on the inner peripheral surface of the focus control ring 13 and is connected to a lens holder 15. The lens supporting member 15 is connected to a lens cylinder 17 body. The focus control ring 13 is rotatably supported between the shutter base (S) and the motor base (B). As shown in FIG. 6, a rotation preventing protrusion 19 formed outside the lens holder 15 is inserted into the motor cover (C) so as to tightly engage with a rotation preventing groove 21.

Order the A7 B7 seal of the Employee Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs. ) In addition, the electronic shutter of the present invention includes an initial position inspection adjustment device, after the electronic circuit part is switched from a power failure to a power-on state and after checking that the focus control ring U is not at the original initial position, or when the shutter switch is operated After calculating the target distance and exposure value; when the shutter starts its operation, it is used to adjust the focus control ring 13 to the initial position. As shown in FIG. 4A, the initial position adjustment device includes a protrusion 131, a gear portion 132 (formed on the focus control ring 13), and a photoresistor 31. When the protrusion Π1 of the focus control ring 13 is not at the initial position * The light-scattering resistor 31 transmits a signal to the power source 1 to rotate the focus control ring 13 clockwise until it reaches the initial position. In addition to having an automatic focus device, the electronic shutter drive device of the present invention also includes an automatic exposure control device.

As shown in FIG. 4B, the elastic element 49 has elastic force in the circumferential direction, and most of the turning portions (T) forming the elastic element 49 are also along the upper and lower sides. 11 This paper scale is applicable to China National Standard (CNS) Λ4 (210X297mm) (Please read the precautions on the back before filling in this K)-Order 3I8S34 Printed A7 B7 by the Beigong Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs. 5. Description of invention () To produce elastic force. The elastic element 49 applies elastic force to a section of lever 'so that a section can be constantly closed. Since the elastic force of the gear lever 45 and the section lever 51 can be absorbed by this structure, the section can be prevented from being double-opened. Connected to the shutter base (S) so that the rotatable gear lever 45 meshes with the section lever 51, and the section lever 51 has a section lock and at the same time is connected to two sections 55 and 57. With this configuration, section 55 The spring 57 is biased towards the closed state by the elastic element 49. When rotating clockwise, the automatic exposure meter 41 pushes against the force of the elastic element 49 and opens the sections 57 and 59. As shown in FIGS. 2 and 8, the sections 57-59 are constructed in a conventional manner, and are held and supported in the shutter seat (S), and are connected to a section cover (SC) on the lower side. -The long groove 61 is formed on at least one side of the section 57, and the long groove 61 is inspected by the photoelectric blocker 63 fixed on the shutter base (S), and the starting point of automatic exposure control is established through this inspection. That is, the segment 57′59 is opened by the clockwise rotation of the automatic exposure meter 41 as indicated by the broken line 57′′59 ”. At this point, the light reflector 63 recognizes the starting point of the opening of the section 57 and allows the control of the exposure value calculated by the photometric circuit section.

Printed by Beigong Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs A7 ____B7___ V. Description of the invention () The starting position is at the middle scale of all automatic focus control scales. At this point, the initial position-adjusting device connected to the focus control lens looks at the position of the focus control ring 13 and controls the initial position. The above operations will be explained with reference to Figures 9 and 10. After the shutter switch is operated, the distance between the measurement circuit and the photometric circuit is calculated and the exposure value is calculated. Second, the shutter is activated or electrolyzed in the electronic circuit in response to the calculated value. When turned on, as shown in FIG. 9, the power supply 1 rotates the clockwise focus control ring 13 and also rotates clockwise. At this time, if the photoelectric blocker 31 located in the gear portion 132 of the focus control ring 13 is at the initial position, the CPU (not shown) causes the calculation device that calculates the value of the drive pulse signal to be "0", and determines the photoelectric block The current state of the device 31 is "H" or "L". The above "H" represents a state where the signal of the light emitting part is cut off and does not reach a photoelectric part, and "L" represents a state where the signal of the light emitting part reaches the photoelectric part and both output signals. Next, a clockwise driving pulse is applied to the photointerrupter 31, and the optical scrambler 31 is again judged to be "H" or "L". If it is in the same state, the computing device adds "1" (S4 scale), and if the photoelectric blocker is not in the same state, the computing device is attributed to the optical scrambler 31 being located in the gear portion 132 of the focus control ring 13, even With clockwise driving pulses, the computing device will return to “〇” repeatedly. If the above driving pulse causes the photo-interrupter to be located in the protrusion 131 of the focus control ring 13, the computing device determines whether the value is higher than a preset fixed value (such as 8, S6 scale), and determines whether the photo-interceptor 31 is in "H" This paper uses the Chinese National Standard Rate (CNS) Λ4 specification (210X29 " / mm) (Please read the precautions on the back before filling this page)

At this time, if it is determined that the photo interrupter 31 is in the "H" state, it can be confirmed that the current position of the focus control ring 3 is at the protrusion 131, a clockwise driving pulse is applied, and the photo interrupter 31 changes from "H" The time to "L" state can also be checked (scales S8 and S9). Finally; as shown in Figure 11, a circuit (not shown) checks whether the power supply state of the stepping drive power supply 1 is at the initial position, and in this state, turns off the power supply. However, if the state of the step driving power supply 1 is different from that shown in FIG. Π, it will continue to apply a clockwise driving pulse, turn off the power after reaching the state shown in FIG. H, and control the focus control ring 13 To the initial position. Secondly, the stepping drive power supply 1 as shown in FIG. Π determines whether the first and third coils are in the “H” state (S10 scale). If it is', the power supply 8 is turned off. The two-drive pulsation is composed, so during one-scale drive, the determination of two "H" or two "L" is possible. When the photo interrupter 31 is located in one of the opening portions 133 of the focus control ring Π, a circuit (not shown) causes the device that counts the number of driving pulse signals to operate the photo interrupter 31, and determines that the state is at or “L”. If the inspection is at "L", the above-mentioned computing device rotates the stepping power supply 1 clockwise until it exceeds a fixed value (such as 8). The above-mentioned rotation of the stepping power supply 1 by the computing device until it exceeds a fixed value depends on When the stepping drive power supply 1 is not in the position shown in figure u, it is used to accurately determine the position of the focus control ring π. The circuit (not shown) is continuously rotated clockwise by the computing device until it exceeds 14 paper music standard universal Chinese stock house standard rate (CNS) Λ4 specifications (210X 297mm) (please read the precautions on the back before filling this page ) Order Γ—Printed by the Employees ’Consumer Cooperative of the Central Prototype Bureau of the Ministry of Economic Affairs ^ 834 A7 B7 5. Description of the invention () Fix the value to check the current position of the focus control ring 13 and reverse the driving pulse to step the driving power supply 1 Counterclockwise rotation (S11 scale). By reverse driving the pulse, the focus control ring 13 rotates counterclockwise, and it is determined whether the initial position of the photo interrupter Π changes from "L" to "H". If it is, the control of the above scale (S10) is completed. After the circuit (not shown) examines the change point, it converts the driving pulse into a normal pulse, rotates the focus control ring 13 clockwise, and controls the focus control ring 13 to its initial position as in the first method. After the initial positions of the focus control lens and the focus control ring Π are set, the focus control lens is moved to an automatic focus position determined by a distance measurement circuit according to the operation of the shutter switch, thereby completing the automatic adjustment. At this time, the focus control lens Π moves to the maximum or minimum zoom position in the direction in which the power supply 1 rotates the focus control ring 13. The focus control lens is integrally connected to the lens holder 15, and since the motor cover member 20 prevents the lens holder 15 from rotating, the rotation operation of the focus control ring 13 causes the focus control lens to move in a straight line. That is, the focus control ring 13 uses a reduction gear part, and rotates clockwise by the power supply 1 (please refer to FIG. 4), the focus control lens zooms toward the section side (toward the bottom shown in FIG. 5), and the focus control ring 13 Zooms toward the target when rotating anticlockwise. Driving a scale, the power supply 1 rotates by 90 °, and the focus control ring 13 also rotates by the same amount. In addition, the focus control ring 13 has most focus control scales. 0 The paper scale is applicable to the Chinese standard (CNS) Λ4 specification (210X297 mm) (please read the precautions on the back before filling this page). Beigong Consumer Cooperative Institution A7 B7 V. Description of the invention () When the focus control is completed, since the power supply 1 has a stable interval of at least 20 ms, the phenomenon of over-rotation can be prevented. In addition, when the focus control is completed, the automatic exposure is performed by the second driving device based on the exposure value calculated by the photometric circuit unit. At this time, the automatic exposure meter 41 as the second driving device rotates clockwise (as shown in FIG. 4A) when overcoming the elastic force of the elastic element 9 according to the applied current, and by connecting to the automatic exposure meter 41 The rotation of the gear lever 45 and the section lever 51 causes the sections 57 and 59 to open. At this time, in order to precisely control the opening time (exposure amount) of the sections 57 and 59, the present invention examines the starting point of exposure. This inspection is realized through the photo reflector 63 to confirm the position of the long groove 61 of the section 57. This output signal is shown in Figure 12. That is, since the photo reflector 63 generates two high pulse signals and two low pulse signals corresponding to the long grooves 61 of the section 57, one of them is used as the starting point of exposure, by which the precise amount of exposure can be controlled . The error signal of the light reflector 63 is shown in Figs. 13A, 13B, 13C and 13D. As shown in the figure, when one of the signals (I), (Π), (melon) and (IV) of the light reflector 63 appears in the signal of the light reflector 63, a control circuit (not shown) judges it as an error state And indicate this error message to a designated device. On the other hand, when the automatic exposure meter 41 receives an opposite current and closes the sections 57 and 59, the elastic member 49 rotates the gear lever 45 counterclockwise by its elastic force.

Printed by the Ministry of Economic Affairs Central Bureau of Accreditation Consumer Cooperative A7 B7 V. Description of invention () There is a magnetized rotor R (please refer to Figure 22A '22B, 22C and 22D). The stepping motor M applies a power of at least 20 m / s to obtain a stable magnetic field before the power is turned off. The electronic shutter drive system of the present embodiment described above performs automatic focus control of the lens according to the drive flow shown in FIG. First, after the initial position of the focus control lens is set to an intermediate scale between the farthest zoom position and the closest zoom position, a distance measurement circuit calculates the distance value of the target, and, in response to this measured value, the focus is controlled by the driving device The lens moves away / close. Assuming that the total number of automatic focus control scales is 40 scales, the initial position of the focus control lens is the 20th scale, the farthest zoom position (b) is the first scale, and the closest zoom position (c) is the 40th scale. The initial position of the lens (a) by positioning the cam surface F chamber of the lens cylinder 4 at the horizontal portion 10 of the cam 8, or by controlling a focus control disclosed in the Korean application 95-33888 filed by the licensee in this case Ring method to set. Since the initial position is set as the starting point of automatic focus control, and the focus control ring connected to the lens is driven clockwise or counterclockwise, the focus control time can be shortened. This will be explained in more detail below. When the shutter starts to operate after the light measurement and the distance measurement are completed, power is applied to the magnet 68 and the restricting element 72 is attached to the magnet 68. The section closing lever 46 in the groove 74 is restricted by the section closing lock 70. In this state, the stepping motor continues to rotate * and the section opening lever 48 is released from the protrusion 23 '. In this way, the elastic element 56 is used to make the section open 20. The paper size is in accordance with the Chinese standard (CNTS) A4 specification (210_X297mm) (please read the precautions on the back before filling this page). A7 _B7_ printed by the quasi-bureau employee consumer cooperative. V. Description of the invention () The lever 48 deviates clockwise as shown (please refer to Figure 19). The clockwise rotation force transmitted to the section opening lever 48 is further transmitted to the worm wheel 58 of the adjustment device, and the helical gear 60 and the adjustment gear 62 are rotated together. The adjustment operation can be realized by an anchor portion 64. That is, although the worm gear 58 is intended to be rotated by receiving the rotational force from the section opening lever 48 via the helical gear 60, since the opposite end of the anchor portion 64 is in mesh with the adjustment gear 62, the rotation of the worm gear 58 is restricted. Therefore, as shown in FIG. 22, the rotation speed of the sector opening lever 48 is slower than the speed of the exposure control ring 28. At this time, as shown in the 22A, 22B, 22C, and 22D, the stepping motor rotates 90 ° at a time. With this rotation, the focus control ring 18 rotates a predetermined angle at a time, and the exposure control ring 28 rotates a tilt (22.5 degrees) at a time. However, since it takes time for the section opening lever 48 to be released from the protrusion 23 'of the focus control ring 18, focus control should not be performed during this period. Therefore, in this embodiment, the cam portion 8 is provided with a horizontal portion 10, so that focus control cannot be performed during this period. The driving method of an electronic shutter during the clockwise rotation of the stepping motor is explained with reference to FIGS. 23 to 28. Immediately after the section opening lever 48 is released from the focus control ring U and the exposure control ring rotates clockwise and the stepping motor rotates in four steps, a normal exposure method is as follows: At the initial position (step 100), the determination step The driving direction of the input motor M is clockwise or counterclockwise (step 110). If the driving direction is clockwise, it is then determined whether the driving step of the stepping motor is odd or even (step 120).

Description of the invention () The dynamic step is an even number, that is, the initial position at step 130 'is the position where the time difference protrusion 36 of the lower gear 32a-2 starts to contact the sliding protrusion 40 of the upper gear 32a-1. Since the time difference protrusion 36 is located in contact with the time difference protrusion 40 ', the rotational force of the stepping motor is transmitted to the focus control ring 18, thereby rotating the focus control ring 18 to the measured distance amount (4 scales). At this time, the exposure control ring 28 connected to the exposure reduction gear 30 receives a clockwise rotation force and moves 4 scales. Although the section opening lever 48 receives the rotation force from the stepping motor M and a rotation force around the lock 52 when performing the focus control, since the anchor 64 and the adjustment gear 62 snap together, the protrusion and 31 'of the exposure control ring 28 are in the area Before the segment pivots to the open position, the rotation of the segment opening lever 48 is restricted. That is, it can prevent the zone from being opened during the focus control. This can be accomplished by restricting the movement of the section opening lever to the open position. The reason is that the speed of the exposure control ring 28 is higher than the speed of the section opening lever 48. When the focus control is completed by the above operation, the stepper motor M is reversed. The clock rotates by 1 scale to perform exposure control, and the section closed lever 46 is in a non-rotatable state because it contacts the end 35 'of the exposure control ring 28 (step 150). That is, the stepping motor M rotates 1 scale counterclockwise so that the lower gear 32a-1 rotates 1 scale clockwise, so that the exposure control ring 28 can rotate 1 scale counterclockwise without the focus control ring 18 rotating, thereby releasing the section Limitation of closed lever 46. 22 This paper scale is applicable to the Chinese National Standard {CNS) Λ4 specification (2 丨 0X297 Gongqing) (Please read the precautions on the back before filling this page)

Description of invention () At this time, although the section closing lever 46 is maintained in a state of being attached to the magnet 68, the section opening lever 48 is flexible The elastic force of the element 56 rotates to the opening position to open the sections. After the exposure is completed as described above, the magnet for exposure control is turned off, and the closing lever 46 can be closed by the biasing force of the elastic element. During this operation, the lower gear 32a-2 rotates 4 scales counterclockwise in response to the initially measured distance in response to the initial measured distance and thereby performs focus control, and then rotates 1 scale clockwise for exposure control. Therefore, the sum of the rotation scales of the lower gear 32a-2 becomes the counterclockwise 3 scales. In addition, the time difference protrusion 36 of the reduction gear is displaced to the right from the initial left position. That is, in the state where the focus control ring 18 rotates 4 scales clockwise, even if the lower gear 32a-2 rotates 1 scale clockwise, the time difference protrusion 36 is The sliding protrusion 40 is in a disengaged state, so the focus control ring 18 does not rotate. Further, the exposure control ring 28 is rotated clockwise by 4 ticks, and then counterclockwise by 1 tick for exposure control. Therefore, the sum of the rotation scales of the exposure control ring 28 becomes 3 scales clockwise. As described above, after the exposure operation is completed, the start of the shutter starts according to a control program unit (not shown). The stepping motor rotates one scale clockwise, so that the exposure control ring 28 can rotate freely by turning the counter-clockwise rotation section closing lever 46 (step 160). At this time, since the time difference protrusion 38 of the lower gear 32a-2 contacts the sliding protrusion of the upper gear 32a-1, the focus control ring 18 rotates when the exposure control ring 28 rotates one scale clockwise. Therefore, from the initial position, the sum of the rotations of the focus control ring 18 and the exposure control ring 28 becomes 4 scales. 23 This paper scale is applicable to China National Standard (CNS) Λ4 specification (210Χ297mm) (please read the notes on the back first and then fill in this page)

At this time, since the magnet 68 is controlled to be energized, the section closing and closing lever 46 is restricted, and the section opening lever 48 is rotated by the biasing force of the elastic member 56 to open the sections. After the exposure operation is completed, the magnet 68 is turned off, and the lever 46 can be rotated to the closed position by the biasing force of the elastic element 54. By rotating the stepping motor M clockwise, 1 scale, the section closed lever 46 then rotates counterclockwise, allowing the exposure control ring 28 to rotate freely to start this initialization operation. At this time, when the magnet 68 is energized and the lower gear 32a-2 is rotated by two steps counterclockwise by rotating the stepping motor, the focus control ring 18 and the exposure control ring 28 are simultaneously retracted to the initial positions, and the time difference protrusion 36 is in contact with the sliding protrusion 40 By this, the initialization operation is completed, and the magnet 68 is turned off.

If the driving direction is clockwise, it is then determined whether the driving scale of the stepping motor is odd or even (step 230). If it is determined that the driving scale rotates 4 clockwise, since the time difference projection 36 contacts the sliding projection 40, the rotational force of the stepping motor is transmitted to the focus control ring 18, thereby rotating the focus control ring by the measured distance (step 240). At this time, the exposure control ring 28 connected to the reduction gear 30 receives a clockwise rotation force and rotates by 4 scales.

At this time, since the segment closing and closing lever 46 cannot be moved by the end 35 'of the exposure control ring 28, the lamp exposure can be achieved. Since exposure in this state The control ring further rotates 〖scale, so the total rotation becomes 6 scales, and the time difference protrusion 38 contacts the sliding protrusion 40.

DESCRIPTION OF THE INVENTION (1) A light bulb exposure method when the focus control ring and the exposure control ring rotate counterclockwise and the stepping motor rotates by 4 scales is described as follows. If the driving direction is counterclockwise (step 220), it is then determined whether the driving scale of the stepping motor is odd or even (step 230). If it is determined that the driving scale is a counterclockwise 4 scale (step 245), since the 4 scale of the lower gear 32a-2 rotates clockwise after its 1 scale rotation, the upper gear and the time difference protrusion 40 are rotated, so the focus control ring 18 rotates 3 counterclockwise Scale. Since the time difference protrusion 38 is in contact with the sliding protrusion 40, in order to maintain the predetermined section opening time equal to the preset lamp opening time, once the magnet 68 is turned off, the section opening lever 48 rotates and completely opens Section. This open state is maintained for a period of time equivalent to the bulb. With the magnet turned off, once the counterclockwise rotation of the lower gear 32a-2 1 scales to release the exposure control ring 28 from the sector closing lever 46, and the magnet 68 is turned off, the sector closing lever 46 pushes the sector open The lever 48 thereby closes all sections and completes bulb photography. In this state, initialization is started by energizing the magnet 68 after rotating the lower gear 32a · 2 counterclockwise. With this control, the total rotation of the lower gear 32a-2 becomes 2 scales clockwise. When the focus control ring and the exposure control ring rotate counterclockwise and the stepping motor rotates by 7 scales, one lamp exposure method is as follows. If it is determined in step 235 'that the driving scale of the stepping motor M is an odd number (7 scales), the time difference protrusion 36 leaving the reduction gear 32a contacts the initial position of the sliding protrusion 40, and the focus control ring 18 rotates after the motor is driven by 1 scale. 31 The size of the paper is applicable to the Chinese threshold family standard (CNS) Λ4 specification (210X297mm) (please read the precautions on the back before filling this page)

Description of invention () Therefore, the total rotation scale of the focus control ring 18 becomes 6 scales. At this time, since the exposure control ring 28 rotates 7 scales counterclockwise, in terms of lamp exposure, the exposure control ring 28 rotates 1 scale clockwise to the state where the focus control ring 18 does not rotate, and the lever 46 can be closed with the exposure control The end 35 'of the ring 28 is engaged. By this operation, the lower gear 32a-2 rotates by 1 scale, and the time difference protrusion 38 comes into contact with the slide protrusion 40. Thereafter, in order to maintain the section opening time equal to the preset lamp time, the magnet 68 is energized, and the section opening lever 48 rotates, thereby completing the opening of the section opening lever 48. After the lamp has been turned on for a predetermined time, the magnet 68 is energized, the lower gear 32a-2 rotates one scale counterclockwise, the section closing and closing lever 46 is released from the exposure control ring 28, and the magnet 68 is turned off again. By this operation, when the section closing lever 46 rotates, the sections are closed, thereby completing the lamp exposure. In this state, initialization is started by controlling the magnet 68 to an energized state after the reduction gear 32a rotates one scale counterclockwise. At this time, the reduction gear 32a is rotated clockwise by 7 scales to control the focus, counterclockwise by 1 scale to maintain the segments in the bulb state, counterclockwise rotated to close the segments, and counterclockwise by 1 scale to initialize.
