Description

SYSTEM AND METHOD FOR DIRECTING AN ELECTROMIC SHUTTER OF A CHAMBER BACKGROUND OF THE INVENTION The present invention relates to a system and method for directing an electronic shutter of a camera, and more particularly, to a system and method for directing an electronic shutter of a camera, wherein the responsiveness of the electronic shutter is fast. and the structure of the electronic shutter is simple. FIELD PE? INVENTION In general, the electronic shutter of a camera is structured such that it automatically connects an automatic focus control, which controls the rapid movement of the camera of a lens for focus control, to a measured distance of a subject, and a Automatic exposure control, which adjusts and controls an iris and shutter speed, according to an appropriate amount of exposure for the subject. The above electronic shutter for cameras is proposed in US Patents. Nos. 4,918,480, 4,634,524, and 5,111,230 and Japanese Patent No. 61-9632. The prior art has in common a focus control ring, which controls the fast approaching / distancing of the lens for focus control, according to a measured distance of the subject, and an interlock device, which stops the rotation of the control ring of focus, when the focus control lens has reached the focus location. Also included are receiver opening / closing means, which open and close a sector according to the convenient amount of exposure for the subject; an exposure control ring, which operates the assemblies to open / close the sector, to its fixed location; a device for initial fixed exposure control, which returns the ring for focus control and ring for exposure control to a fixed position immediately following the exposure; and an energy source that operates the focus control ring and the interlock device. In the prior art as before, with respect to the method for fast displacement control of the lens for focus control, the focus control ring gradually moves the focus control lens from a minimum rapid displacement location to a location of maximum fast displacement and vice versa. Previously, the minimum fast scroll location indicates that the focus lens location for focus control in which the subject is in the furthest distance, and the maximum fast scroll location refers to the location of the lens focus of the subject. Focus control where a subject is in the closest distance. With reference to Figure 29, a displacement sequence of an electronic obturator of the U.S. patent. Nos. 5,111,230, illustrated. As can be seen in the drawing, lens for focus control moves quickly away from the minimum rapid displacement location (j) to the maximum rapid displacement location (k) by the focus control point. After the focus control lens quickly moves away at the measured distance (1) it is returned to the opposite direction to the minimum fast displacement location (j). Recently, in order to improve the focus control functions of the electronic shutter, the focus control steps that are employed from the minimum fast scroll location to the maximum fast scroll location are further multiplied. Resulting from this use of additional multiplied stages is the increase in focus control time, slowing down the responsiveness of the electronic shutter. That is, if the first stage of the focus control ring employs [X] more amount of time required to go from going from start to end (from the minimum fast shift control location to the maximum fast displacement control location or vice versa) is the amount [maximum stage No. X] plus time, which uses an excessive amount of time for focus control. As well, in the electronic shutter of the prior art, an interlocking device is required to stop the rotation of the ring for focus control when the focus control lens moves away rapidly according to the measured distance of the subject, resulting in a complicated structure . COMPENDIUM OF THE INVENTION The present invention has been made in an effort to solve the above problems. It is an object of the present invention to provide a method and device for electronic shutter movement for a camera which, by shortening the moving distance of a focus control lens, rapidly shifts the focus control lens outwardly in accordance with A measured distance of a subject and therefore reduce the amount of time spent for focus control, improves the responsiveness of an electronic shutter. Another object of the present invention is to provide a method and device for electronic shutter displacement for a camera that by eliminating the use of an interlock device, used to stop the rotation of a focus ring when the focus control is completed, achieves a simpler structure and operational stability. The above objects are achieved in accordance with the present invention which provides an electronic shutter displacement method in which an initial focus of a rotating member connected with a focus control lens is adjusted in a state where the lens for control of The focus is pre-adjusted in an average position between a maximum rapid displacement position and a minimum rapid displacement position. The initial position of a focus control lens is located at a middle stage between a focus position of the focus control lens with respect to a pre-adjusted fuzzy subject and a focus position of the focus control lens with respect to to the closest subject. And then, the focus is controlled by rotating the rotating member connected to a first displacement assembly from an initial position to an address in a clockwise or counterclockwise direction in order to move the lens from focus control to a set position according to a value calculated by a distance measuring circuit in which a shutter switch is operated. Finally, the exposure is carried out by a sector closing / opening means, which is operated according to an exposure value calculated by a luminescent measurement circuit that connects sectors that are derived through an elastic member, with second assemblies of displacement that rotate in both directions, depending on the application of the electrode, when the focus control of the focus control lens is terminated. According to another aspect of the present invention, a system for shifting the electronic shutter of a camera comprises a first displacement assembly including a power supply and a rotating member that engages with the displacement assemblies that rotate in the same direction as the power supply, and rapidly moving the focus control lens in response to a value calculated by a distance measurement circuit. Mounts for detecting and adjusting the initial position, adjust the rotary member to an initial position when the rotating member is not placed in an average position between the maximum rapid displacement position and the minimum rapid displacement position, when the initial power supply is Applies to the camera. Second displacement assemblies, which open / close sectors are displaced according to an exposure value calculated by the luminescent measurement circuit when an energy source is applied, while the sectors, derived by the elastic member, are kept closed.

DESCRIPTION OF PREFERRED MODALITIES Preferred embodiments of the present invention are now described in detail with reference to the accompanying drawings. With the reference of Figure 1 the reference letter (a), refers to an initial portion of a lens for focus control. The initial position (a) of the focus control lens is set between a minimum rapid displacement position (b) and a maximum fast displacement position and by first displacement assemblies, a focus lens rapidly moves away according to a value of measured distance, measured by a distance measurement circuit. With reference to the above, considering that the total number of stages in the previous automatic focus control is 40 stages, the initial position is a twenty-second stage, the maximum rapid displacement position (c) is the forty-second stage and the displacement position Minimum fast (b) is the first stage. More specifically, the electronic shutter displacement method of the present invention fixes the initial position (a) of the rapid lens shift for focus control at the starting point of the auto focus position control and when rotating a rotating, connected member The lens, either in a clockwise direction (C) or counterclockwise (CCW), performs an automatic focus control of the focus control lens. As a result, the present invention reduces the fast travel time when going from the minimum fast travel position to the maximum fast travel position and vice versa, at a level of at least half of the prior art. Figures 2-8 will now be referred to to explain an electronic shutter displacement system for cameras of the present invention operating as before. In Figure 2 illustrating an integral electronic shutter displacement device for cameras according to a preferred embodiment of the present invention, the reference number 1 refers to an energy source of first displacement assemblies. This power source 1 is constituted by a motor gear 3, formed integrally with 4 permanent magnets and a pair of stators 5. When it travels, the energy source 1 can rotate 90 ° at a time in a direction of direction to the clock hands or counterclockwise by the 4 permanent magnets. The power source 1 is located on a motor base (b) and a motor cover (C) is connected to its upper side. Also, the first displacement assemblies include a gear portion for speed reduction, coupled with the power source and transmitting rotating force. The gear reduction gear portion illustrated in Figures 3, 4A, and 4B in more detail comprises a plurality of gears 7, 9 and 11 coupled together. The gear 7 engages with the gear of the motor 3 of the power source 1 and the gear 11 is coupled with a ring for focus control 13 connected to the lens for focus control. The gear portion for speed reduction is located on a plug base (S) and is connected to the bottom of the motor base (B). As illustrated in Figure 5, a helicoid (H) is formed on the inner circumference of the focus control ring 13 which is connected to the lens holder 15. The lens holder 15 integrally connects to a lens barrel 17. The focus control ring 13 is rotatably supported between the obturator base (S) and the motor base (B). As illustrated in Figure 6, a projection to prevent rotation 19 formed on the exterior of the lens holder 15, is inserted into the engine cover (C), such that it is tightly engaged with a groove to prevent rotation 21. Thus, in accordance with the direction of rotation of the focus control ring 13 connected to the power source 1, the lens holder 15 moves in an upward and downward direction on the slot to prevent rotation 21 formed on the cover motor (C) when seen in Figure 5. The coil springs 23, which act as elastic members, are sandwiched between the lens barrel 17 and the motor cover (B) and prevent free movement caused by the coupling of the ring for focus control 13 and lens holder 15 (see Figure 2). As illustrated in Figure 13, the lens barrel 17 intersperses the coil spring 23 between a slot 25 formed in a projection 29 of the lens barrel 17 and a pin 27 formed in the engine cover (C) and thus, the lens barrel 17 is structured to always receive the force in the upward direction (in the drawing). In addition, the lens shutter of the present invention includes mounts for initial position detection and regulation to adjust the focus control ring 13 to the initial position when the electronic circuit portion is activated from a deactivated state and then it is detected that the The focus control ring 13 is not in the predetermined starting position, or when the shutter starts operation after the distance of the subject and the exposure value have been calculated when the shutter switch is operated. As can be seen in Figure 4A, the initial position regulation detection assemblies comprise a projection 131, a gear position 132 (formed in the focus control ring 13) and a photo-switch 31. When the projection 131 of the ring for The focus control 13 is not in the initial position, the photo switch 31 sends the signal to the power source 1 to rotate the focus ring 13 in a clockwise direction until it reaches the initial position. In addition to having an automatic focus device, the electronic shutter displacement device of the present invention also includes an automatic exposure control device. This automatic exposure device has an automatic exposure meter 41 and a separate displacement mount which is a second displacement assembly. With reference to Figures 2, 4A and 4B, the automatic exposure meter 41 includes an elevation 43 that rotates in one direction or the other, according to the direction in a direction that applies electric current. The lug 43 engages a detent projection 47 of the clutch lever 45, which is supported by a plug base (S) in such a way that it can rotate. An electrical member 49 is fixed to the gear lever 45 and resiliently supported by the plug base (S).

As a result, the automatic exposure meter 41 always receives elastic force in the counterclockwise direction and when it is rotated in the clockwise direction, it does so by pushing against the elastic force of the member elastic 49. As can be seen in Figure 4B, elastic member 49 has elastic force in a circumferential direction and a plurality of turns ((T) forming elastic member 49 creates elastic force also in an up and down direction. elastic member 49 applies elastic force to a sector lever 51, such that a sector can always remain in a closed state, since the rebound of clutch lever 45 and sector lever 51 can be absorbed by this structure, the The sector's double opening can be avoided, and also the gear lever 45 engages with the sector lever 51 that joins the shutter base (S), so that and rotating and the sector lever 51 has a sector processor 53 and is simultaneously joined with two sectors 55 and 57. Through this structure, the sectors 55 and 57 are derived by the elastic member 49 in the closed state. While rotating in a clockwise direction, the automatic exposure meter 41 pushes against the force of the elastic member 49 and opens the sectors 57 and 59.

As illustrated in Figures 2 and 8, sectors 57 and 59 are structured in the conventional manner, secured and supported on the shutter base (S) and joined with a sector cover (SC) on their lower sides. A slot 61 is formed at least on one side of the sector 57 and the slot 61 is detected by a fixed photoreflector 63 in the shutter base (S) and through this detection, a starting point of the automatic exposure control is established. That is, sectors 57 and 59 open as illustrated on dotted lines 57 'and 59' by the clockwise rotation of automatic exposure meter 41. At this point, photoreflector 63 recognizes the open starting point of sector 57 and allows control of exposure value calculated by the light measurement circuit portion. Based on the electronic shutter displacement device as explained above, the method of moving the electronic shutter and the operation of this mode will now be explained. First, an initial position is established such that the initial fast-moving / approaching position of the focus control lens is located at the central stage of all the automatic focus control stages. At this point, the mounts for regulation and initial position detection detect the position of the focus control ring 13 connected to the lens for focus control and control the initial position. The above operation will now be described with reference to Figures 9 and 10. After the shutter switch is operated, the circuit portion for distance measurement and the circuit portion for light measurement calculate the distance and exposure values of the subject. Then, when either of the shutter starts in response to the calculated values or the energy is activated in the electronic circuit position, the power source 1 rotates clockwise and as illustrated in Figure 9, the Focus control ring 13 also moves in the clockwise direction. At this time, if it is assumed that the placement of the photo-switch 31 in the gear portion 132 of the focus control ring 13 is in an initial position, the UPC (not shown) releases a counting assembly, which counts the number of signals of shift pulse to "O" and determines whether the present state of photo switch 31 is at? 'or' L '. In the above, it represents a state when the signal of a luminescent portion is interrupted and does not reach a photoelectric portion, and 'L' represents a state where the signals of the luminescent portion reach the photoelectric portion and when both are output signals.

Next, a clockwise processing pulse is applied to the photo switch 31 and again determined whether the photo switch 31 is in? 'Or' L '. If it is in the same state, the counter mounts are added by "1" (step S4), and if the photo switch 31 is not in the same state, the counter is released to O '. Here, because the photo-switch 31 is placed in the gear position 132 of the focus control ring 13, even a displacement pulse is applied in a clockwise direction, the counter assembly is repeatedly released at '0' . If the photo switch is placed on the projection 131 of the focus control ring 13 by the displacement pulse in the clockwise direction, the counter assemblies determine whether the value is above a predetermined fixed value (for example, 8) (step S6) and it is determined whether the state of the photo-switch 31 is in an 'H' state. At this time, if it is determined that the status of the photo switch is at 'H', it is recognized that the present location of the ring for focus control 13 is on its projection 131, a displacement pulse clockwise is applies, and the time when the state of photo switch 31 is changed from 'H' to 'L' is detected (steps S8 and S9).

Finally, a circuit (not shown) verifies whether the energy application state of the displacement energy source in steps 1 is in the initial position, as illustrated in Figure 11, and the power is interrupted in this state. However, if the state of the phased displacement energy source l is not identical to that illustrated in Figure 11, a clockwise displacement pulse is applied continuously, the power is interrupted after reaching a state of that illustrated in Figure 11, and the focus control ring 13 is controlled to the initial position. Next, the stepped power source 1 illustrated in Figure 11 determines whether the first and second coils are in the 'H' state (step S 10) and if they are, the power is interrupted or turned off. As a step of the energy source for displacement in steps 1 is composed of two displacement pulses, the determination of two 'H' or two 'L' is possible during displacement by one stage. When the photo-switch 31 is located in an open portion 133 of the focus control ring 13, the circuit (not shown) releases the assemblies, which count the number of displacement pulse signals at '0' operated by the photo-switch 31, and determines if his present state is in 'H' or 'L'.

If it is detected to be in 'L' the above counter assemblies rotate the energy source of displacement in steps 1 in the direction clockwise until it exceeds a fixed value (for example 8). In the above, the rotation of the energy source of displacement in steps 1 by the counter assemblies until a fixed value passes, is for an accurate determination of the position of the focus control ring when the initial position of the power source Step 1 is not in a position as illustrated in Figure 11. The circuit (not shown) detects the present location of the focus control ring 13 in the upper portion 133 by continuous rotation in the clockwise direction clock of the counter assemblies until the fixed value has passed, and the displacement pulse is reversed, such that the energy source of displacement in steps 1 rotates in the counterclockwise direction (stage S) eleven). By the reverse displacement pulse, the focus control ring rotates in the counterclockwise direction, and it is determined whether the initial state of photo switch 13 has changed from 'L' to 'H' and if it has done so , the control of the previous stage (S 10) is carried out. After the circuit (not shown) detects the change point, converts the shift pulse to a normal pulse, rotates the focus control ring 13 clockwise and the focus control ring 13 is controlled to its initial position as in the first method above. After the initial position of the lens for focus control and focus control ring 13 is established, in accordance with the shutter-switch operation, and the focus control lens is quickly moved away to an automatic focus location, determined by the distance measuring circuit, thus realizing automatic focus. At this point, the focus control lens 13 moves to the maximum or minimum fast displacement location according to the direction in which the power source 1 rotates the focus control ring 13. The focus control lens integrally joins the lens holder 15 and because the lens holder 15 is prevented from rotating by the motor cover member 20, the rotary operation of the focus control ring 13 moves the focus control lens into a linear direction. That is, the focus control ring 13 is rotated in the clockwise direction (see Figure 4) through the use of the gear portion for speed reduction by the power source 1, the lens The focus control is rapidly moved to the sector side (towards the bottom of Figure 5) and moves rapidly towards the subject when the focus control ring 13 is rotated in the counterclockwise direction.

Here, the power source 1 is rotated by 90 ° when it moves in one step and the focus control ring 13 is also rotated by the same amount. In addition, the focus control ring 13 has many focus control stages. At the time when the focus control is completed, as the power source 1 has at least a stabilization interval of 20 ms, an overflow phenomenon is prevented. Also, at the time the focus control is completed, automatic exposure is performed according to the exposure value calculated in the light measurement circuit portion by the second displacement assembly. Here, the automatic exposure meter 41 as the second displacement assembly rotates in the clockwise direction (in Figure 4A) while overcoming the elastic force of the elastic member 49 in accordance with the application of an electric current, and by the rotation of the gear lever 45 and the sector lever 51 connected to the automatic exposure meter 41, the sectors 57 and 59 are opened. At this time, to precisely control the opening time (exposure amount) of sectors 57 and 59, the present invention detects the starting point of exposure. That detection is made through the photoreflector 63, recognizing the location of the slot 61 of sector 57. This output signal is illustrated in Figure 12.

That is, since the photoreceptor 63 generates two high pulse signals and two low pulse signals corresponding to the slot 61 of sector 57, one of both is used as an exposure starting point and by doing so, a precise amount can be controlled. of exposition. Error signals from the photo reflector 63 appear in Figures 13A, 13B, 13C and 13D. As illustrated, when the signal of the photoreflector 63 appears as one of the signals (III) and (IV) of the photoreflector 63, a control circuit (not shown) determines that the state is an error state and indicates an error message to an indication device. On the other hand, as sectors 57 and 59 close when the automatic exposure meter 41 receives an opposite electrical current, the elastic member 49 rotates the gear lever 45 in the counterclockwise direction by its elastic force. [Second Mode] The following description comprises a system and method of displacement for electronic shutter according to a second embodiment of the present invention with reference to Figures 14 and 29. First with reference to Figures 16 and 17, a lens barrel 4 is located on the inside of a plug base 2 and also on a cam barrel for focus control 6, and is structured such that it can be subjected to fast moving away in the direction of the barrel axis of the cam cam. according to the amount of rotation and direction of the cam barrel for focus control 6. This rapid lens shift is generally achieved by the movement of the lens barrel in response to the cam curvature. The cam barrel for focus control 6 of the preferred embodiment includes a cam position 8. The cam portion 8 includes a horizontal portion 10, which corresponds to the initial position; a first cam portion 2, which extends towards the front of the horizontal portion 10 following the inside face of the cam barrel for focus control 6; and a second cam portion 14 extending towards the rear of the horizontal portion 10 following the inner face of the cam barrel for focus control 6. A fork 16 is formed on one side of the cam barrel for focus control 6. The fork 16 is a mounting for receiving the rotational force of the focus control ring 18, fixed able to rotate on the outer circumference of the shutter base 2. The focus control ring 18 includes a pin 20 attached to the fork 16, and teeth 22 are formed around approximately half the outer circumference of the ring for focus control 18. also, the projection 23 is formed extending outwardly on the outer circumference of the ring for control of focus 18. The final gear of the portion for speed reduction 24 engages with the teeth 22 and is structured to allow the reception of the rotational force by a stepper motor (M). The portion for speed reduction 24 receives rotational force from a single power source and comprises a gear train for first dividing and transmitting this rotational force to the ring for control of focus 18 and ring for control of exposure 28. As a result, the portion for speed reduction 24 has a gear for speed reduction 30 for exposure control and a plurality of gears for speed reduction 32A, 32B, 32C, 32d and 32e for focus control. A motor gear 34 is also provided which is a two-level gear. Due to its structure, the motor gear 34 is attached to both the reduction gear 30 and the plurality of reduction gears 32A-32C. Through the previous assembly of gears, the teeth 22 engage with the gear for speed reduction 32E which is the final gear of the portion for speed reduction 24 and receives the rotational force. The first gear for speed reduction 32A is constituted by a gear of upper portion 32a-l of a gear of lower portion 32a-2 and as illustrated in Figure 1, are fixed with a range of one arrow (S) and are able to rotate. The anterior arrow (S) is rotationally structured to have a fixed interval with the upper and lower gears 32a-1 and 32a-2. Projections with time difference 36 and 38 are formed in the lower gear 32a-2 at an angle corresponding to a stage. A sliding projection 40 is formed in the upper gear 32a-l and disposes between the time difference projections 36 and 38. The upper gear 32a-l of the speed reduction gear 32A engages with a gear for adjacent speed reduction 32b of way that is able to transmit energy to him. The lower gear 32a-2 engages with the motor gear 33 in order to receive the rotational force of the stepper motor. The exposure control ring 28 is provided on its outer circumference as a plurality of projections 29 'and a plurality of projection 31' which are disposed between the projections 29 '. The projections 29 'and 31' are arranged at an angle of 22.5 °. The projections 31 'are provided respectively with extension ends 35' extending outwardly.

The exposure control ring 28 and the focus control ring 18 are arranged concentrically and are relatively rotatable. In a periphery portion of the rings 28 and 18, a sector opening / closing assembly is provided to open and close the sectors. The sector opening / closing assemblies according to this embodiment comprise a sector closing lever 46 rotatably coupled to the plug base 2 by a pin 50, an open sector lever 48 rotatably engaged in the plug base 2 by a pin 52 and elastic members 54 and 56 for respectively applying rotational force in a clockwise direction to sector locking lever 46 and sector opening lever 48. One end of each of elastic members 54 and 56 it engages the shutter feed 2, and each of the other ends is respectively engaged in the sector lock lever 46 and the sector opening lever 48. A regulator assembly is provided on one side of the open sector lever 48 to control exposure. In this embodiment, the regulating assemblies comprise a helical gear 58 formed integrally to one end of the lever 48, a helical wheel 60 which engages with the helical gear 58, a regulator gear 62 arranged on a common axis with the helical wheel 60 for rotate with it and an anchor 64 that will be hooked on the regulating gear 62.

The worm wheel 60, the regulating gear 62 and the anchor 64 all rotatably engage the plug base 2. As illustrated in Figure 19, the other end of the sector open lever 48 is connected by a pin 66 to the pair of sectors SI and S2 in such a way that it can open and close sectors SI and S2. The sector locking lever 46 is restricted or not restricted by a magnet 68. That is, when electrical power is applied to the magnet 68, the lever 46 is restricted, and when it is not applied to the magnet 68, the lever 46 is not restrict This operation is achieved by providing a sector closure pin 70 in the sector closure lever 46 such that the pin 70 can be located in a slot 74 of a restriction member 72, which is reciprocated by the magnet. 68. In this embodiment, the stepper motor M employed as a pulse source to displace the motor gear 34, in a positive or negative direction, is divided into four sections at an angle of 90 ° and has a magnetized rotor R (see Figs. 22A, 22B, 22C and 22D). The stepper motor M is applied with electric power at a speed of at least M / S in order to obtain magnetic field stabilization before the electric power is interrupted or turned off. The electronic shutter displacement system described above according to this embodiment performs automatic lens focus control in accordance with the pulse process as illustrated in Figure 9. First, after an initial position of the focus control lens is it establishes in the middle stage between the farthest fast displacement position (B) and the closest fast displacement position (C), a distance measurement circuit calculates the distance value object and in response to the measured value, the lens Focus control is fast approaching / moving away within the displacement assembly. Here, considering that the total number of steps or stages of the automatic focus control is 40 stages, the initial position of the focus control lens becomes the twenty-second stage, the farthest forward position is returned to the first stage, and the nearest fast-moving position (c) the fortieth stage. The initial position (a) of the lens is established by placing a cam floor F of the lens barrel 4 in the horizontal portion 10 of the cam portion 8, or alternatively, by a method of controlling a focus control ring described in FIG. Korean patent application No. 95-33888 filed by the present assignee.

Therefore, since the initial position (a) is set as a starting point of the automatic focus control and the focus control ring connected to the lens, it moves in a clockwise or counterclockwise direction clockwise, the focus control time can be shortened. This will be described in more detail below. When the shutter starts to operate after finishing the light measurement and distance measurement, electrical energy is applied to the magnet 68 and the restriction member 72 is connected to the magnet 68, such that the sector closing lever 46 located in the the slot 74 is restricted by the sector closure processor 70. In this state, the stepper motor continues its rotation and the sector opening closure lever is released from the projection 23 '. By this operation, the sector opening lever 48 is derived by the elastic member 56 in a clockwise direction in the drawing (see Figure 19). The rotational force clockwise transmitted to the lever for sector opening 48 is further transmitted to the helical gear 58 of the regulator assembly and rotates the worm wheel 60 together with the regulating gear 62, so that the operation of governed can be achieved by the anchor 64.

That is, although the worm gear 58 is intended to rotate upon receipt of the rotary force from the sector opening lever 48 by the worm wheel 60, since opposite ends of the anchor 64 reciprocate with the regulating gear, the rotation of the worm gear 58 It is restricted. As a result, the rotary speed of the sector opening lever 48 becomes slower than that of the exposure control ring 28 as illustrated in a graph of Figure 22. At this point, the stepper motor, as illustrated in Figures 22A, 22B, 22C and 22D, it rotates through an angle of 90 ° at a time. By this rotation, the focus control ring 18 rotates at a pre-determined angle to time, and the exposure control ring 28 rotates by one step (22.5 °) at a time. However, since it takes time for the sector opening lever 48 to be released from the projection 23 'of the focus control ring 18, the focus control will not be performed during this period. Therefore, in this embodiment, the horizontal portion 10 is provided on the cam portion 8 such that the focus control can not be performed during this time. Now, an electronic shutter displacement method during the clockwise rotation of the stepper motor will be described with reference to Figures 23 to 28, immediately after the sector opening lever 48 is released from the projection 23 of the focus control ring 18 and when the focus control ring and the exposure control ring rotate clockwise and the stepper motor rotates in four stages, a normal exposure method is like follows: In the initial position (step 100), it is determined whether the direction of travel of the stepper motor M is one direction in the clockwise direction or one direction in the counterclockwise direction (step 110) . If the direction of travel is the direction of the clockwise direction, then it is determined whether the step step of the stepper motor is a non number or an even number (step 120). If the displacement step is an even number, such as a step 130, the initial position starts as a position where the time difference projection 36 of the lower gear 32a-2 contacts the sliding projection 40 of the upper gear 32a-l. Since the time difference projection 36 is in a contact state with the time difference projection 40, the rotational force of the stepper motor is transmitted to the focus control ring, thus rotating the focus control ring as much as the measured distance amount (4 stages). At this point, the clamping ring 28 connected to the gear for reduction of exposure speed 30 receives a rotational force in the clockwise direction and moves in four stages. Although the sector opening lever 48 receives a rotational force clockwise relative to the pin 52 while receiving the rotational force from the step motor M and performs focus control, since the anchor 64 engages the Regulating gear 62, projections 29 'and 31' of the exposure control ring 28 restrict rotation of the lever for sector opening 48 before the sectors pivot to the open position. That is, the sectors are prevented from opening during the focus control time. This is done by restricting the movement of the sector opening lever to the open position since the angular velocity of the exposure control ring 28 is greater than that of the sector opening lever 48. When the focus control is completed by the above operation, the step motor M rotates in the counterclockwise direction by a step to allow exposure control while the sector closure lever 46 is in a state where it can not rotate since contacts the 35 'end of the exposure control ring 28 (step 150). That is, the counterclockwise rotation of the stepper motor M in one stage rotates the lower gear 32a-l clockwise by one stage, such that the exposure control ring 28 can rotate counterclockwise by a stage, in a state where the focus control ring 18 does not rotate, thereby releasing the restriction of the lever for sector closure 46. At this point , although the sector closing lever 46 is maintained in a state connected to the magnet 68, the sector opening lever 48 rotates to the open position by the elastic force of the elastic member 56 to open the sectors. After completing the exposure as described above, the magnet for exposure control is interrupted such that the sector closure lever 46 can be closed by the bypass force of the elastic member. During this operation, the lower gear 32a-2 performs the focus control by turning counterclockwise by four stages through the step motor M in response to the initial measurement distance and then turns in the direction of the clock hands by a stage for exposure control. Therefore, the resulting number of rotary stages of the lower gear 32a-2 becomes three stages in the counter-clockwise direction. In addition, the time difference 36 of the gear for speed reduction is shifted to the right from the initial left position. That is, in a state where the focus control ring 18 rotates clockwise by four stages even when the lower gear 32a-2 rotates clockwise by one stage, the ring The focus control 18 does not rotate since the time difference projection 36 and the slide 40 are in a detached state. In addition, the exposure control ring 28 rotates clockwise by four stages and then rotates counterclockwise by a stage for exposure control. Subsequently, the resulting number of ring rotation stages for exposure control 28 is turned three steps in the clockwise direction. After completing the exposure operation as described above, a shutter initialization starts according to a command from a control process unit (not shown). The stepper motor rotates clockwise by a step to allow the exposure control ring 28 to rotate freely by turning the sector closure lever 46 counterclockwise (step 160). ). In this point, since the time difference projection 38 of the lower gear 32a-2 contacts the sliding projection of the upper gear 32a-l, the focus control ring 18 does not rotate while the exposure control ring 28 rotates in the direction of the hands of the clock for a stage.

Therefore, from the initial position, each resulting rotation of both the focus control ring 18 and the exposure ring 28 becomes four stages. In this state, the magnet connected to the sector closing lever 46 is activated (step 170) and in this way the stepper motor rotates in the counterclockwise direction by 5 steps, to return the control ring from focus 18 to the initial position. In addition, when the stepper motor is rotated, the exposure control ring 28 which has been passed counterclockwise by 1 stage rotates clockwise by one step to return to the second stage. initial position, and the time difference projection 36 comes into contact with the sliding projection 40, thereby completing the mechanical initialization of the shutter. Since the exposure control ring 28 is in a state where it is rotated by a further step, the stepper motor is rotated in an opposite direction by a step to return the exposure control ring 28 to the initial position, completing the initialization of the exposure control ring 28 (step 180) and when the magnet is interrupted (step 190), the control operation is completed (step 200). When the focus control ring and the exposure control ring rotate clockwise simultaneously and the stepper motor rotates 7 stages, a normal exposure method is as follows: The speed reduction gear 32a in the counterclockwise direction by seven stages (step 130-1) wherein the rotation of the focus control ring 18 is the same as that of the exposure control ring 28 and the lever for closure of sector 46 is frees from the exposure control ring. At this point, since the magnet 68 restricts the sector locking lever 46, the sector closing lever does not operate. According to this, the sectors maintain their open state. The sectors close when the exposure is complete and the magnet 68 goes off or interrupts. The operation for initialization of the sectors after completing the exposure will be described below. An initialization of the shutter starts according to a command of a control process unit (not shown). The stepper motor rotates clockwise by a step to allow the exposure control ring 28 to rotate freely by turning the sector lock lever 46 counterclockwise (step 160). At this point, since the time difference projection 38 of the lower gear 32a-2 contacts the sliding projection of the upper gear 32a-l, both the focus control ring 18 and the exposure control ring 28 rotate in the direction of the hands of the clock for a stage. Therefore, from the initial position, each resulting number of rotating stages of both the focus control ring 18 and the exposure control ring 28 is returned to eight stages. In this state, when the magnet connected to the sector closing lever 46 is activated, in this way the stepper motor rotates to rotate the lower gear 32a-1 in the counterclockwise direction in 9 stages, the focus control ring 18 is returned to the initial position. However, since the exposure control ring 28 is in a state where it is rotated by a further stage, the stepper motor is rotated in an opposite direction by a step in order to return the exposure control ring 28 to the initial position, and at the same time the time difference projection 36 comes into contact with the sliding projection, thus completing the initialization and shutdown of the magnet. When the focus control ring and the exposure control ring rotate counterclockwise simultaneously and the stepper motor rotates 4 stages, a normal exposure method is as follows: In step 125, it is determines whether the offset number of the step motor M is an even number stage or a non number stage.

If the determined number is an even number stage, in step 135, the step motor M rotates with the even number stage and in step 145, the step motor rotates in the opposite direction by a step. As previously, since the time difference projection 36 of the speed reduction gear 32a contacts the sliding projection 40, the rotational force is subsequently transmitted to the focus control ring 18 by a step, thereby rotating the Focus control 18 in the counterclockwise direction by three stages. At this point, the exposure control ring 28 connected to the reduction gear 30 rotates clockwise by four stages while receiving rotational force in the clockwise direction. At this stage, to perform the exposure operation, when the lower gear 32a-2 rotates counterclockwise by one stage, the sliding projection of the upper gear 32a-l comes to contact the difference projection of the second gear. time 36, such that the focus control ring does not rotate while the exposure control ring 28 rotates clockwise by a step to allow the sectors to be capable of an open state.

At this point, since the magnet 68 is controlled to an on state, the sector closure lever 46 is restricted, and the sector opening lever 48 is rotated by the bypass force of the elastic member 56, thereby opening the sectors. After finishing the exposure operation, the magnet 68 is turned off so that the sector opening lever 46 can rotate to the closed position by the bypass force of the elastic member 54. By turning the stepper motor M in the direction clockwise by one step, the sector lock lever 46 then rotates counterclockwise to rotate the exposure control ring 28 free, thereby starting the initialization operation. At this point, since the time difference projection 36 of the lower gear 32a-2 contacts the sliding projection 40 of the upper gear 32a-l, both the focus control ring 18 and the exposure control ring 28 rotate in the clockwise by one stage. Therefore, each resulting number of rotating stages of the rings 18 and 28 become two stages from the initial position. At this stage, when the magnet 2068 is activated and the lower gear 32a-2 rotates in the counterclockwise direction by two stages when the stepper motor is turned, both the focus control ring 18 and the ring exposure control 28 are simultaneously returned to the initial position and the time difference projection 36 comes to contact the sliding projection 40, thereby completing the initialization operation and turning off the magnet 68. When both the focus control ring and the exposure control ring rotates counterclockwise and the stepper motor rotates 7 stages, a normal exposure method is as follows: In step 125, it is determined whether the motor shift number of the steps M is an even-numbered stage or a non-numbered stage. If the determined number is a non-numbered stage, in step 135, the stepper motor M rotates 7 stages. As previously, since the time difference projection 36 of the speed reduction gear 32a contacts the sliding projection 40, the rotational force is subsequently transmitted to the focus control ring 18 by a step, thereby rotating the Focus control 18 in the counterclockwise direction by six stages. As a result, the time difference projection 40 comes to contact the time difference projection of the lower gear 32a-2., and the sector closing lever 46 reaches a state where it can rotate. At this point, since the magnet 68 is controlled to an on state, the sector closure lever 46 is restricted, and the sector closure lever 48 is rotated by the bypass force of the elastic member 56, thereby opening the sectors. After finishing the exposure operation, the magnet 68 is turned off so that the sector closure lever 46 can rotate to the closed position by the bypass force of the elastic member 54. By turning the stepper motor M in the direction counterclockwise by one stage, the sector lock lever 46 then rotates counterclockwise to rotate the exposure control ring 28 free, thereby beginning the operation of initialization. That is, in a state where the time difference projection 38 in the lower gear 32a-2 contacts the time difference projection 40 of the upper gear. 32-1, by the rotation in the stepper motor stage M, the time difference projection 36 comes to contact the sliding projection 40 and the exposure control ring 28 rotates in the clockwise direction by a step . Therefore, each resulting number of pivoting steps of the focus control ring 18 and the exposure control ring 28 becomes 5 stages. At this point, by controlling the magnet 68 to an on state and rotation of six stages of the step motor M in the counterclockwise direction, both the focus control ring 18 and the exposure control ring 28 they are simultaneously returned to the starting position, and the magnet 68 is turned off. A semi-exposure method will be described below with reference to Figures 24, 27 and 28, when the focus control ring and the position control ring rotate clockwise and the stepper motor rotates 4 steps . The semi-exposure differs from the normal exposure since the magnet 68 for adjusting the sector opening time can not remain in an on state. Therefore, in a state in which the sector closure lever 46 engages the end 35 'of the exposure control ring 28, after turning off the magnet and exposing as much as the bulb time, the operation of Initialization In the initial position, the time difference 36 that is provided in the lower gear 32a-2 of the speed reduction gear 32a contacts the sliding projection 40 that is provided in the upper gear 32a-l (step 210).

It is determined whether the direction of travel of the stepper motor M is an address in the clockwise direction or a counterclockwise direction (step 220). If the direction of travel ee in the direction in a clockwise direction, then it is determined whether the step step of the stepper motor is a non number or an even number (step 230). If it is determined that the displacement step rotates clockwise by four stages, since the time difference projection 36 is in a state of contact with the difference projection of time 40, the rotational force of the stepper motor is transmitted to the focus control ring, thereby rotating the focus control ring as much as the measured distance amount (step 240). At this point, the exposure ring connected to the gear for reduction of exposure speed 30 receives rotational force in the clockwise direction and rotates four stages. By the above operation, as the focus control is completed, the magnet 68 is controlled to a disconnected state to maintain the sector opening state as well as the preset bulb time (step 250). Therefore, the sector opening lever 48 rotates to open the sectors and in that state, after a predetermined amount of time passes, the magnet 68 turns off.

To close the sectors, when the stepper motor M is turned clockwise by one step after completing the semi-exposure to close the sectors (step 260), the sector closing lever 46 becomes free of the end 35 'of the focus control control ring 28. In this state, when the magnet 68 is controlled to a disconnected state (step 270), the sectors are closed by the bypass force of the elastic member 54 of the closing lever of sector 46. And then, for the initialization operation, the lower gear 32a-l is rotated in the counterclockwise direction by one step (step 280) and the magnet 68 is activated (step 290). By this operation, since the resulting number of rotating stages of the gear for speed reduction becomes six stages in the clockwise direction, the gear for speed reduction will rotate in the counterclockwise direction by six stages for initialization. However, since the sliding projection 40 of the upper gear 32a-l contacts the time difference projection 36 of the lower gear 32a-2, when it is rotated in the counterclockwise direction by six stages, there is an error by a stage when the focus control ring 18 is moved.

To compensate for the error, after turning the lower gear 32a-2 clockwise, it locates the focus control ring 18 to the initial position by turning it counterclockwise by six stages, when the reduction gear 32a is rotated in the counterclockwise direction by a step to return both the speed reduction gear 32a and the exposure control ring 28 to the starting position, the difference projection of time 36 and the sliding projection 40 are moved to the initial position and in this way the exposure control ring 28 is also returned to the initial position (step 300). In this state, the electrical energy that has been applied to the magnet 68 is interrupted, thereby completing the exposure control (step 310). When the focus control ring and the exposure control ring rotate clockwise and the stepper motor rotates seven stages, a semi-exposure method as follows: In the initial position where the time difference 36 which is provided in the lower gear 32a-2 of the speed reduction gear 32a, contacts the sliding projection 40 that is provided in the upper gear 32a-l if it is determined that the stage of displacement of the stepper motor M is seven stages in the clockwise direction (step 240-1), the lower gear 32a-2 rotates counterclockwise by 7 stages, and both the focus control ring 18 and the control ring of exposure 28 rotate clockwise 7 steps. For semi-exposure, the focus control ring 18 does not rotate and the reduction gear 32a rotates clockwise by one stage, such that the sector closure lever 46 can engage the end 35 'of the exposure control ring 28. By this operation, the focus control ring 18 does not rotate, and the exposure control ring 28 rotates counterclockwise by one stage so that the sectors can open and the time difference projection 38 comes to contact the sliding projection 40. In this state, to maintain the sector opening time as well as the predetermined bulb time when the deactivated or disconnected magnet 68 is rotated, the opening lever sector 48 rotates to fully open the sectors. At this point, since the sector locking lever 46 can not be moved by engaging the end 35 'of the exposure control ring 28, semi-exposure is performed. Since this state is that the exposure control ring rotates additionally clockwise by one stage, the resulting rotation becomes six stages and the time difference projection 38 comes into contact with the sliding projection 40. After to complete the semi-exposure, the magnet 68 is controlled to an activated state. In this state, in order to close the sectors, the lower gear 32a-2 rotates in a counterclockwise direction by one stage, so that the sector locking lever 46 can be detached with the end 35 'of the ring exposure control 28. When the magnet 68 is then deactivated, the sector closing lever rotates to close the sectors. If this state, when the lower gear 32a-2 is rotated in the counterclockwise direction by one stage, and activates the magnet 68, the resulting rotation of the lower gear 32a-2 becomes 8 stages. Here, when turning the gear for speed reduction 32a clockwise by 8 stages, initialization is achieved. However, when the gear for speed reduction rotates clockwise in a state in which the time difference projection 36 of the gear for speed reduction 32a, contacts the sliding projection 40, an error occurs for a step when the ring is moved for focus control 18. To compensate for the error, after turning the lower gear 32a-2 clockwise in 9 stages and returning the ring with focus light 18 to the initial position, when the lower gear 32a-2 is rotated counterclockwise by a step to return both the speed reduction gear 32a and the control ring of exposure 28 to the initial position (step 300), the time projection 36 rotates to the initial position when contacting the sliding projection 40 and the exposure control ring 28 is also returned to the initial position. When the focus control ring and the exposure control ring rotate counterclockwise and the step motor rotates 4 steps, a semi-exposure method will be described below. If the direction of travel is the opposite direction to the clockwise direction (step 220). Next, it is determined whether the step-up step of the stepper motor is a non-number or an even number (step 230). If it is determined that the step of displacement is 4 stages in the counterclockwise direction (step 245), since the clockwise rotation of 4 stages of the lower gear 32a-2 rotates the gear 32a-2 and the time difference projection 40 after its rotation of one stage, the focus control ring 18 rotates counterclockwise by 3 stages.

Since the time difference projection 38 is in a contact state, with the sliding projection 40 to maintain the predetermined sector opening time as well as the predetermined bulb opening time, when the magnet 68 is deactivated, the Sector opening 48 rotates to fully open the sectors. This open state remains as long as the bulb time. In a state in which the magnet 68 is activated, when the lower gear 32a-2 is rotated in the counterclockwise direction by a step to release the exposure control ring 28 from the sector lock lever 46 and when the magnet 68 is deactivated, the sector closing lever 46 pushes the sector opening lever 48, thus closing the sectors and completing the bulb photograph. In this state, the initialization starts by activating the magnet 68 after rotation in the counterclockwise direction of the lower gear 32a-2. By this control, the resulting rotation of the lower gear 32a-2 is returned in the clockwise, two-step direction. When the focus control ring and the exposure control ring rotate counterclockwise and the stepper motor rotates to 7 stages, a semi-exposure method is as follows: In step 235 ', it is determined that the displacement step of the step motor M is a non number (7 stages), from the initial position where the time difference projection 36 of the gear for speed reduction 32a contacts the projection 40, the focus control ring 18 rotates after a motor stage. Accordingly, the resulting number of pivoting steps of the focus control ring 18 becomes 6 stages. At this point, since the exposure control ring 28 rotates in the counterclockwise direction by 7 stages, for semi-exposure, the exposure control ring 28 rotates clockwise by one step. in a state where the focus control ring 18 does not rotate, such that the closing lever 146 can engage the end 35 'of the exposure control ring 28. By this operation, the lower gear 32a-2 arrives to rotate a stage, and the time difference projection 38 comes into contact with the sliding projection 40. After this, to maintain the sector opening time as well as the preset bulb time, the magnet 68 is deactivated and the lever sector opening 48 rotates, thereby completing the opening of the closing opening lever 48.

After opening the bulb for a predetermined time, the magnet 68 is activated, the lower gear 32a-2 rotates counterclockwise by a step to release the sector closing lever 46 from the end 35 'of the exposure control ring 28 and the magnet 68 is deactivated again. By this operation, since the sectors are closed while the sector closing lever 46 rotates, the semi-exposure is completed. In this state, the initialization starts by controlling the magnet 68 to an on state after the speed reduction gear 32a rotates in the counterclockwise direction by one stage. At this point, the gear for speed reduction 32a rotates clockwise in 7 stages for focus control, counterclockwise by one stage, to keep the sectors in a state of bulb, in the counterclockwise direction by a stage to close the sectors and in the counterclockwise direction by a stage for initialization. Therefore, the resulting rotation of the gear for speed reduction 32a becomes four stages from the starting position. The control ring 18 rotates by the gear for speed reduction 32a in the counterclockwise direction by six stages, turn clockwise by one stage, to close the sectors and turn clockwise by a stage for initialization. Therefore, the resulting rotation of the ring for focus control becomes four stages. The exposure control ring 28 rotates counterclockwise by 7 stages for focus control, clockwise by one stage for exposure, clockwise by one stage to close the sectors and in the counterclockwise direction by a stage for initialization. Therefore, the resulting number of rotating steps of the exposure control ring 28 becomes 4 stages. At this point, since the time difference projection of the speed reduction gear 32a contacts the sliding projection 40, for initialization, the stepper motor M rotates clockwise by 4 stages, to rotate the lower gear 32a-2 in the counterclockwise direction by 4 stages, completing the initialization. Finally, the magnet 68 is controlled to a disconnected state.
