Abstract

PURPOSE:To facilitate the unloading of a film by coupling a motor for rewinding with a rewinding transmission system in the middle of blank feeding operation for automatic loading, and powering on the rewinding motor forcibly in the direction of disconnection from the rewinding transmission system in case of a failure in the automatic loading. CONSTITUTION:The rotation of a 1st motor M1 connected to a motor control circuit 660 is reduced in speed by a speed reduction transmission system 600 and a planetary clutch 610 switches the transmission system. Namely, when the motor M1 rotates forward, the clutch 610 operates the shutter charging mechanism 624 and mirror driving mechanism 622 in a mirror box driving mechanism 620 and the phases of their outputs are sent out to the circuit 660 by using a phase detecting means 630. Further, when the motor is in backward rotation, the clutch 610 operates a film rewinding driving mechanism 700 and the output of a rewinding completion detecting means 710 is sent to the circuit 660. If the loading fails during the repetition of this operation, the clutch 610 is switched to disconnect the mechanism 700 and next blank feeding operation is made ready.

It is determined that 02 is rotating and turns on and off repeatedly.
If the signal is stopped, the microcomputer MC2 is on the sprocket.
It is determined that 402 has stopped. Step 30
When lag A is 1, go to step 33; when flag 8 is 0
Then, the process branches to step 31. Immediately after the autoloading sequence starts, step 23
Since flag A is set to 0 in step 31,
branch out [Step 31] The previous state of input port P9 and the current state
Compare with the state of If it has changed, go to step 32.
If there is no change, go to step 36. [Step 32] The input state of input port P9 has changed.
Therefore, flag A is newly set to 1. [Step 33] Same as step 31, input port P9
Compare the previous state and the current state, and if there is a change, change the status.
Go to step 34, and if there is no change, go to step 36. [Step 3.1] The input state of input port P9 changes.
Therefore, flag A is newly set to O. [Step 35] Count the energization time of the second motor M2.
Then, restart the timer from the beginning. [Step 36] Since there was no change in input port P9,

If there is no change in speed, sprocket 402 is stopped.
It is determined that the time is 350 milliseconds, and the process goes to step 37.
If the time has not passed yet, go to step 38. [Step 37-1] Stop energizing the second motor M2.
Then, the empty charging sequence (step 37-2) described below is performed.

If flag C is 0, go to step 39.
Branch into. Immediately after the autoloading sequence starts
Since the flag C is set to O in step 25, the step
The process branches to step 39. [Step 39] The previous state of the input port PIO and the current state
Compare with the current state. If it has changed, step 10
If there is no change, return to step 30. [Step 10] Input state of input port PIO changes
Therefore, flag C is newly set to 1. Then step 3
Returns to 0 and continues autoloading operation.

[Step 41. ] Compare the previous state of input port PIO with the current state. If it has changed, step 4
If no change has occurred, the process returns to step 30 to continue the autoloading operation. [Step 42] Since the input state of the input port PIO has changed, the flag C is newly set to O. [Step 43] Since the input capo 1-PLO signal has been switched from off to on, it means that the -equal winding has been completed, and this is the memory that counts the number of winding frames during autoloading. Increment memory G. [Step 44] 3 empty windings during autoloading
Check if the piece is finished. If after finishing 3 frames, go to step 48; if not after finishing 3 frames AL, go to step 45
Branch into. [Step 45] Check whether 4 frames of film have been blankly wound during autoloading. If 4 frames have been completed, the process goes to step 46; if the AL4 frames have not been completed, the process returns to step 30 to continue autoloading. [Step 16] Since one frame of film has been emptied during autoloading, the second motor M2 is stopped. [Step 47] Data is transmitted to the DR of the display driving IC to display a display indicating that autoloading has been completed, and then the process branches to step 22 described above to end the process. [Step 48] Steps 48 to 53 are a sequence regarding switching of the film drive method after the completion of 3-frame winding. In step 48, the second feeding motor M2 is once stopped. [Step 49] Wait 100 milliseconds until the second motor M2 completely stops. [Step 50] To switch the film drive method, the second motor M2 is reversely rotated (the sun gear 406 rotates clockwise as shown in FIGS. 8 and 9(b)). [Step 51) Time reverse energization for 100 milliseconds (9th
energization until the state shown in Figure (c) is reached. [Step 52] Stop the reverse rotation of the second motor M2. [Step 53] Wait 100 milliseconds until the second motor M2 completely stops. Thereafter, the process returns to step 28, and empty winding is performed in the autoloading of the fourth and final frame. Specifically, the second motor M2 once again rotates in the normal direction (Fig. 8,
As shown in FIG. 9(d), the sun gear 406 rotates counterclockwise again. However, in this state, Fig. 9 (d
), the rotation of the second motor M2 is not transmitted to the sprocket 402 but to the spool 401. Therefore, in such a sprocket-free state, if the film 52 is actually fed in the winding direction (by rotation of only the spool 401), and the sprocket 402 is rotated by the meshing of the film perforation 54 and the sprocket 402, If the autoloading has been successful, but the sprocket 402 is not rotating, it is determined that the autoloading has failed, for example, because the film leader portion 64 is not properly wound around the spool 401. I'll come. Next, the empty charging sequence shown in FIG. 13C will be explained. As explained in the autoloading sequence (FIG. 13B), the empty charging sequence is performed when it is determined that the sprocket 402 stops rotating during autoloading. Further, as will be described later, the program jumps from the rewinding sequence shown in FIG. 13E. [Step 37-2] In order to start mirror up, the first motor M1 is energized in the forward direction (as shown in FIG. 3(a). (b) and FIG. 5(a)). When the sun gear 104 rotates counterclockwise, the counterclockwise rotation state of the sun gear 104 is started. [Step 54] A timer for counting the energization time of the first motor M1 is started. [Step 55] When the brush starts moving, it is made to wait 15 milliseconds so as not to be affected by gearing H and 4'J. [Step 56] Check the state of the input port P11 (output signal of the operation end detection pattern 162 in FIGS. 3 and 4). The signal input to the input port pH is the third
This signal is linked to the mirror drive gear 120 and shutter charge gear 140 (mirror drive cam 121, shutter charge cam 141) explained in FIG. Completion of shutter charging and completion of mirror up can be detected as a change in potential in a sliding state between the operation completion detection pattern 162 (conducted to the ground level) and the operation completion detection pattern 162. Specifically, upon completion of shutter charging (the movable mirror 70 is in the down state), the input port pH turns on (potential changes from the initial level to the ground level), and the movable mirror 70
The ground pattern 161. The phase between the operation end detection pattern 162 and the brush 122 is set. In step 56, if the mirror-up completion state is reached, the process branches to step 60, and if the mirror-up completion state has not yet been reached, the process branches to step 57. For reference, the relationship between the input port pH and the input port P12 will be explained here. The input port P12 becomes the output signal of the overrun detection pattern 163 in FIGS. 3 and 4, and when the rotating brush 122 and the overrun detection pattern 163 are in a sliding state, the first motor is activated when the shutter charging is completed. The amount of overrun of M1 (a state in which it rotates from when it is controlled to stop until it actually stops) and the amount of overrun of the first motor M1 when mirror up is completed are within the allowable setting range. Detection of presence or absence can be determined as a change in potential. Specifically, if the input port PL2 remains off (initial level) when the shutter charge is completed, the overrun amount is within the setting range, and if it turns on (changes from the initial level to the ground level), the overrun claw is set. It can be determined that the range has been exceeded. Further, if the input port P]2 remains on when the mirror up is completed, the overrun amount is within the set range, and if it is turned off, it can be determined that the overrun amount exceeds the set range. In addition, rMI of input ports P12 and P12 (M is normally input port pH is turned on when shutter charging is completed (mirror down state), input port P12 is turned off, and input port pH is turned on when the movable mirror 70 starts to rise. , input port P12 is on, input port pH is off when mirror up is completed (shutter charge is released), input port PI
2 is on, input port pH is off during shutter charging (while movable mirror 70 is lowering), input port PL
2 is off. [Step 57] Check the timer that measures the time since the first motor M1 is energized. If 500 milliseconds have elapsed, go to step 58;
If 0 milliseconds have not elapsed, the process returns to step 56. [Step 58] Since the mirror drive was not completed within the time, it is determined that an accident has occurred and the energization of the first motor Ml is stopped. [Step 59] Display data is output to the DR of the display driving IC so as to display an accident, and the process jumps to step 22. [Step 60] Now that the mirror has been raised, the mirror is lowered (shutter charge). Therefore, timer #2 is restarted. [Step 61] As explained in step 56, the phase of the mirror down (shutter charge is completed) is adjusted.
Since the pH is turned on, in step 61 the input port p
H is checked, and if the mirror down (shutter charge) is completed, the process branches to step 63, and if the mirror down (shutter charge) is not completed, the process branches to step 62. [Step 62] Check the timer that measures the time since the first motor Ml is energized. If one second has elapsed, the process branches to step 58; if one second has not elapsed, the process branches to step 61. [Step 63] Mirror down (shutter charge)
Since this has been completed normally, the first motor Ml is de-energized and jumps to step 22. This completes the empty charging sequence. Next, the rewinding sequence shown in FIG. 13D will be explained. The rewind sequence is performed when the rewind button 14 is pressed, as described in the processing flow after power supply. Furthermore, as will be described later, the film jumps when the film ends during normal winding and the winding tension state is reached. [Step 64], [Step 65] Flags A and C used for subsequent processing are cleared to O. [Step 66] Check the battery voltage FAT. The method is the same as step 26 of the autoloading sequence, so we will omit the details (If the battery is sufficient, go to step 68; if the voltage is low, go to step 67. [Step 67] To the DR of the display driving IC data to display a warning that the voltage has dropped,
After that, the process branches to step 22 and the process ends. [Step 68] It is checked whether the movable mirror is in the phase where it is down (shutter charging completed), and if the mirror is correctly down (shutter charging completed), the process branches to step 76. If the movable mirror is not in the correct down state but has stopped midway (shutter charging has stopped midway), the process branches to step 69. [Step 69] The first motor M1 is rotated forward to lower the movable mirror to the correct position (to complete shutter charging). [Step 70] Start a timer for counting the energization time of the first motor M1. [Step 71] As explained in step 56, the input port p
Since the H switch is turned off, the input port pH is checked in step 71, and if the mirror down (shutter charge) is completed, the process proceeds to step 75, and if the mirror down (shutter charge) is not completed, the process branches to step 72. do. [Step 72] Check the timer that measures the time since the first motor M1 is energized. If one second has elapsed, the process returns to step 73; if one second has not elapsed, the process returns to step 71. [Step 72] Since the mirror drive has not been completed within the second second, it is determined that an accident has occurred and the energization of the motor M1 is stopped. [Step 74] Display data is output to the DR of the display driving IC so as to display an accident, and the process branches to step 22 to end the process. [Step 75] Mirror down (shutter charge)
Since this has been completed normally, the energization of the first motor Ml is stopped. Thereafter, the process proceeds to step 76. [Step 76] In order to release the spool-side planetary gear 411 in the state shown in FIG. 9(d) from the spool-side transmission gear 409 (fleet the spool 401 as non-meshing), start reverse rotation of the second motor M2. . [Step 77] Wait 100 milliseconds to ensure that the spool-side planetary gear 411 is released. [Step 78] First motor M for rewinding
Start reversing l. That is, as shown in FIG. 5(b), the sun gear 104 is rotated clockwise to engage the planetary gear 105 and the rewind gear 201, and then the rewind gear 201 is rotated. [Step 79] Start a timer that counts the energization time of the first motor Ml. [Step 80] Check flag A, which is a flag for storing the previous state of input port P9. When flag A is 0, the previous state of input port P9 is memorized as the switch-on state, and the flag is When A is 1, the previous state of input port P9 is memorized as the switch-off state.As mentioned above, the signal input to input port P9 is a signal linked to sprocket 402, and winds the film evenly. During the return, a signal that turns on and off multiple times (for example, 12 times) is input, and if the on and off signal is input repeatedly, the microcomputer MC2 determines that the sprocket 402 is rotating, and turns on and off. If the off (return signal) has stopped, the microcomputer MC2 determines that the sprocket 402 has stopped. In step 80, if flag A is 1, the process branches to step 83; if flag A is O, the process branches to step 81. [Step 81] Compare the previous state and current state of input port P9. If there has been a change, proceed to step 82; if not, proceed to step 86. [Step 82] Input state of input port P9 has changed, so the flag A is set to 1. [Step 83] Similar to step 81, compare the previous state and current state of input port P9, and if it has changed, proceed to step 84; if not, proceed to step The process branches to 86. [Step 84] Since the input state of the input port P9 has changed, the flag A is newly set to 0. [Step 85] The timer for counting the energization time of the first motor Ml is restarted. [Step 86] Check the timer that counts the energization time of the first motor Ml, and if there is no change in the power port for 350 milliseconds, it is determined that the sprocket 402 is stopped, and step If the time of 350 milliseconds has not yet elapsed, the process branches to step 90. [Step 87] Stops energizing both motors M1 and M2. Then, the process proceeds to step 88. [Step 88] Winding Check whether the return is completely completed. If the frame counter is O, the process branches to the above-mentioned empty charge sequence, and if the counter remains, the process branches to step 89. [Step 89] DR, which is a display driving IC. Display data indicating that rewinding has stopped midway is sent out, and the process branches to step 22 to end the process. [Step 90] Check flag C, which is a flag that stores the previous state of input port PIO. do. When the flag C is 0, the previous state of the input port PIO is stored as a switch-on state, and when the flag C is 1, the previous state of the input port PIO is stored as a switch-off state. Note that the signal input to input port I) 1.0 is a signal linked to the sprocket 402 as described above, and is
The switch is turned on when rewinding corresponding to the equal portion is completed. Also, if you continue rewinding the next frame of the film, it will turn off immediately, and it will turn on again when the rewinding of the next frame is completed. Therefore, by detecting this signal, MA-132MC2 can control the winding of film frames. In step 90, when flag C is 1, the process branches to step 93, and when flag C is O, the process branches to step 91. [Step 91] The previous state of the input port P10 and the current state are compared. If it has changed, the process advances to step 92; if it has not changed, the process returns to step 80 and continues rewinding. [Step 92] Since the input state of the input port P10 has changed, the flag C is newly set to 1. Then step 80
and then continue rewinding. [Step 93] The previous state of input port PIO is compared with the current state. If it has changed, the process advances to step 94; if it has not changed, the process returns to step 80 and continues rewinding. [Step 94] Since the input state of input capo-1-PIO has changed, the flag C is newly set to O. [Step 95] Since the signal at the input port PIO has been switched from off to on, it means that l-equal rewinding has been completed, and the memory counting the number of frames is subtracted. Thereafter, the process returns to step 80 to continue returning. Next, the release sequence shown in FIG. 13E will be explained. As explained in the processing flow after power supply, the release sequence performs processing when the release enable button 12 is pressed. [Step 96] Communicates with the AD converter AD2 and reads the photometric AD conversion value. [Step 97. lit! Based on the II optical AD conversion value, the shutter speed and aperture value are transmitted to the display driving IC and DR. [Step 98] Perform a voltage check. The voltage is checked, and if the voltage has dropped, the process branches to step 99, and if the voltage is such that it can be released, the process branches to step 100. The voltage check here only checks whether the release can be performed. For example, when the voltage value Vo is less than 3 volts, the process branches to step 99, and when V O > 3 volts, the process branches to step 99. [Step 99] Display data is sent to the DR of the display driving IC to display a warning that the voltage has decreased. (Step 100) Check the voltage again. Check the voltage, and if the voltage is quite high, go to step 101, and if the voltage is not so high, go to step 102. The voltage check here will allow you to release the shutter, but the subsequent It is determined whether or not superimposed current can be applied to the motor during operation. For example, when the voltage value V is 4 volts, the process branches to step 102, and when the voltage value V is 4 volts, the process branches to step 102. Branch to 101. [Step 101] Set the flag E, which is a flag indicating that the voltage is high, to 1. [Step 102] Set the flag E, which is a flag that indicates that the voltage is low, to 0. [Step 103] Mirror In order to improve
The normal rotation of the motor Ml is started. [Step 104] Start timer #2, which is a timer that counts the energization time of the first motor M1. [Step 105] Wait 15 milliseconds until the ratunyu current at the start of energization subsides. [Step 106] The flag E, which is a flag storing the high/low voltage state, is checked. If the voltage is high, the process branches to step 108, and if the voltage is low, the process branches to step 107. [Step 107] If the voltage is slightly low, wait an additional 15 milliseconds for the rush current to recover. [Step 108] A high level signal is output from the output capo P23, and power is supplied so that the third motor M3 for driving the aperture blades on the lens side can be driven. after that,
The microcomputer MC3 on the lens side is commanded to narrow down the aperture blades of the lens to the position of the calculated aperture value. [Step 109] Check the input port pH,
If the mirror up is completed, the process branches to step 111; if the mirror up is not completed, the process branches to step 110. [Step 110] Check the timer that measures the time since the first motor Ml is energized. If 500 milliseconds have elapsed, go to step 112; 5
If 00 milliseconds have not elapsed, the process returns to step 109 and waits until the mirror up is completed. [Since the mirror-up operation did not end during step 1123500 milliseconds, it was determined that this was an accident, and the first motor
Stop energizing l. [Step 113] Display data is output to the DR of the display driving IC so as to indicate an accident, and the process branches to step 22 to end the process. [Step 111] Since the input port pH is turned off and mirror up is completed (shutter charge is released), the power supply to the first motor Ml is stopped. Next, in steps 200 to 203, a case will be described in which the amount of overrun of the first motor M1 at the time of mirror up completion exceeds a predetermined amount. [Step 200] Wait 3 milliseconds to allow time for overrun. [Step 201] Check the input port P12. As described in detail in the explanation of the empty charge sequence (Fig. 13c) above, if the overrun amount when mirror up is completed is within the set range, input port P12 is turned on and the process branches to step 114 to perform normal operation. However, when the overrun amount exceeds the set range, the input port P12 is turned off and the process branches to step 202 as an abnormal state avoidance sequence. Here, we will explain the problem when the overrun amount exceeds the set range (that is, the mirror drive gear 1
20 may further rotate clockwise, and in the worst case, 12
1b and one end 131 of the mirror drive lever 130 come out of sliding contact, and the one end 131 comes into sliding contact with the downward cam surface 121c, causing the movable mirror 70 to rotate in the downward direction (direction of the viewfinder observation position). A problem arises in that the film 52 cannot be properly exposed. [Step 202] The first motor Ml is energized again in the normal rotation direction. As a result, the mirror drive gear 120 rotates clockwise again, and is movable by sliding between the mirror drive cam 121 and the mirror drive lever 130. mirror 70
mirrors down once - and then continuously mirrors up again. In addition, the shatter chain gear 140 also rotates counterclockwise again, causing the shack charge lever 150 to rotate for charging and for charging release. However, even if the shutter charge lever 150 rotates again in this state, the shutter unit 300 will only be charged empty and will not be adversely affected in any way. [Step 203] Wait for 50 milliseconds, which is the time required for the brush 122 shown in FIG. 4 to slide at least on the operation completion detection pattern 162, before the first motor Ml is operated again. Then, return to step 109 again and when mirror up is completed (input port pH is off),
In step 111, the rotation of the first motor M1 is stopped. In this state, the overrun amount is within the set range, and the process proceeds to step 11/I. [Step 114] Communicate with lens microcomputer MC3,
Check whether the aperture has been stopped down to a predetermined position, and if the aperture blades 530 have been stopped down to the predetermined position, step 115
If the aperture has not been completed, the process returns to step 114 and waits until the aperture blades 530 are apertured. [Step 115] A high level signal is output from the output port P13 for 10 milliseconds to energize the coil 383 of the electromagnet for controlling the front curtain of the shutter to run the front curtain of the shutter. This starts the film exposure operation. [Step 116] Waiting for film exposure time. [Step 117] A low level signal is output from the output port P14 for 10 milliseconds to energize the coil 389 of the electromagnet for controlling the shutter trailing curtain to run the shutter trailing curtain. This completes the film exposure operation. [Step 118] Switch S linked to completion of trailing curtain travel
Determine whether CN 2 is on or off. If it is off, the process remains at step 118 and waits until the switch is turned on. If it is on, it means that the trailing curtain has completed running, so the process branches to step 119. [Step 119] The flag E, which is a flag that stores the high/low voltage state, is checked. If the voltage is high, the process branches to step 123, and if the voltage is slightly low, the process branches to step 123. [Step I20] Check the voltage again. This voltage check has the same meaning as the voltage check in step 100, and as a result, when the voltage is high (for example, V.
o<4 volts) branches to step 122. To check the voltage, as described above, the leading curtain coil MG31 and the trailing curtain coil MG32 are energized at the same time for 10 milliseconds, and the voltage during the energization is checked. [Step 121] Flag E is set to 1 to indicate that the voltage is high. [Step +223' To indicate that the TX pressure is slightly low, rub the flag O (Step 123) Lower the mirror and start energizing the first motor Ml in the normal direction to churn the gloss. [Step I24] Start timer #2, which is a timer that counts the energization time of the first motor M. [Step 125] Start the timer #2, which is a timer that counts the energization time of the first motor M. Wait for milliseconds. [Step 126] Check flag E, which is a flag that stores the high/low state of the voltage. If the voltage is high, the process branches to step 128; if the voltage is slightly low, the process branches to step 1.27. [Step 127] If the voltage is a little low, wait an additional 15 milliseconds for the rush current to recover. [Step 128] Command the lens side microcomputer MC3 to return the lens aperture blade 530 to the open position. [Step 127] 129] Communicates with the lens microcomputer MC3 and checks whether the aperture has been returned to the open position. If the aperture blades 530 are open, the process goes to step 130; if the aperture is not open, the process returns to step 129, and the aperture is returned to the open position. Wait until it is released. [Step 130] Energize the second motor M2 in the forward rotation direction to wind the film evenly. [Step 131] Timer #l that counts the energization time of the second motor M2. [Step 132] to [Step 135] Clear the discrimination flags used in the following processing, and set A=O, B=O, C2O, F=O. [Step 136] At the input port P11. Check the input status.If the manual status is on, it means that the mirror has finished lowering and the gloss has been charged, so step 1
If it is off, the process branches to step 142 because the mirror has not been completely down. [Step 137] Since the mirror down (shutter charge) has been completed, the first motor Ni 1 is stopped. [Step 138] Check the flag B that stores whether only the first motor M1 for mirror drive (shutter charge) is operating or whether the second motor M2 for winding is also operating at the same time. If the flag B is 0, the process branches to step 151, and if the flag B is 1, the process branches to step 139. [Step 139] Set the status flag B to O. [Step 140] The fact that the status flag B is 1 means that the second hoisting motor M2 is temporarily stopped. In step 140, the second winding motor M2 is energized again. [Step 14I] Restart the timer #l that counts the energization time of the second winding motor M2. Thereafter, the process branches to step 151. [Step 142] First motor Ml for driving the mirror
Check timer #2, which counts the energization time, and set 1.
If a second has elapsed, the process branches to step 143; if one second has elapsed, the process branches to step 145. [Step 143] First motor M1 for driving the mirror
Since one second has passed without the mirror down or shutter charging being completed, the first motor M1 for winding and rewinding is stopped, and only the first motor M1 is operated independently, and the mirror down and shutter charging are completed. Only the shutter charge is performed first. At this time, if the second winding motor M2 has already stopped, the process branches to step 146. [Step 144] A flag E storing the high/low state of the battery voltage BAT is checked, and if the voltage is high, the process branches to 146. [Step 145] If the status flag B for determining status flag B is 1, that is, the first motor M1 for driving the mirror is in operation, the process returns to step 136 and waits until the mirror down is completed. When the status flag B is O, that is, when the second winding motor M2 is also operating at the same time, the process branches to step 204. [Step 146] The second winding motor M2 and the mirror driving first motor M1 are de-energized. [Step 147] Since charging has stopped midway through the DR of the display driving IC, display data is sent to display an accident display. [Step 148] A second winding motor M2;
Since simultaneous driving with the first motor M1 for driving the mirror could not be performed, the second motor M2 for sweeping up the mirror is stopped. [Step 149] First motor Ml for driving the mirror
Restart timer #2, which counts the energization time. [Step 150] Set status flag B to 1, and motor M
1. Since it was not possible to energize M2 simultaneously, it is remembered that the energization of the second hoisting motor M2 was stopped. Thereafter, the process returns to step 136 and continues to detect the completion of mirror down (shutter charging). [Step 204] Check whether the first motor Ml for driving the mirror (for shutter charging) is in operation, and if it is in the stopped state, the process branches to step 151, and if it is in the operating state, the process branches to step 154. This step 204 is performed in the abnormal state avoidance sequence in subsequent steps 205 to 208.
In the event of an abnormality, the first motor Ml for driving the mirror is rotated one more rotation, and as a result, the operation of the first motor Ml for driving the mirror (shutter charge) ends before the second motor M2 for winding ends. This step was inserted because there are cases where this step is later. [Step 1511 Check whether the second winding motor M2 is in operation or stopped. If it is in operation, the process branches to step 154; if it is stopped, the process branches to step 152. [Step 152] Check the memory F that stores how many times the input signal of the input port P9 is switched on and off while winding one frame. If the film is switched only four times or less while winding one frame, the film will be switched immediately (or at the same time) after the second motor M2 was stopped by the signal (input port PIO) indicating completion of winding one frame during the previous winding. is pushing forward,
When the driving force of the second motor M2 is lost, it is determined that the sprocket 402 has returned a little in the rewinding direction, and jumps to the above-mentioned rewind mode (step 64).On the other hand, the on/off switching signal When input more than 4 times, the process branches to step 205.The meaning of step 152 will be explained in more detail.The length of the film 52 varies depending on each manufacturer and winter film. Although it is called film, it is well known that it can actually take 25 images.Also, this is also caused by variations in the number of stones used during autoloading.Furthermore, the film 52 itself also has a base. Because it is a synthetic resin sheet,
It is also known that it can be slightly elongated by stretching. Therefore, even if it is possible to wind one frame of the film 52 near the final photographable frame of the film 52, the film 52 is actually stretched slightly before the winding of one frame is completed (the cartridge shaft of the film cartridge 50 All of the film 52 wound around the cartridge 51 is fed in the direction of the spool 401, and even if an attempt is made to wind up the film 52 by the rotation of the spool 401, the film 52 cannot be pulled out from the cartridge 50. However, there are cases in which the winding of one frame is possible because the film 52 has been stretched. In such a case, the second motor M
When the winding driving force of the spool 401 is lost at the stop of step 2, the film 52 contracts due to its own return force, and the sprocket 402 rotates slightly in the unwinding direction due to engagement with the film perforation yon 54. Put it away. Therefore, the next time the winding for the next piece is carried out,
■Before winding evenly, a 1-frame winding completion signal is input to input port P], 0, and even though the proper 1-frame winding has not actually been performed, the output signal is In some cases, a signal indicating that one frame of winding was completed was generated. In the conventional sequence, shooting is OK even in such a case, but there are cases where the exposure is the next equal amount, resulting in double exposure that the photographer did not intend, and no matter how many times the film is wound, the film is This caused a problem in which it was not possible to detect tension (end of film). Step 152 of this embodiment is a step inserted in order to solve the above-mentioned conventional problem. The on/off switching signal to port P9 is output a predetermined number of times (in the example, this predetermined number is set to 4 times, but theoretically, the on/off switching signal that is output when winding one frame under normal conditions) If the film 52 does not reach the predetermined number (it is sufficient to set a number smaller than
) solved the conventional problem by making the step hen jump. Next, a case will be described in which the overrun ratio of the first motors P and 11 reaches a predetermined value of -42 when the shutter charging (mirror down) is completed in steps 205 to 208. [Step 205] Check input capo-1-PI3. As described in detail in the above explanation of the blank firing sequence (FIG. 13C), if the overrun (■) at the completion of the shutter charge (mirror down) is within a predetermined range, the input port P12 is turned off and the process proceeds to step 153. The routine branches to Step 206, but when the overrun amount exceeds the set range, the input port P12 is turned on, and the routine branches to Step 206, which is an abnormal condition avoidance sequence. Here, to explain the problem when the overrun amount exceeds the set range, that is, the mirror drive gear 120 may rotate further clockwise than the state shown in FIG. 3(a). In the worst case, mirror drive cam 1
21 and one end 131 of the mirror drive lever 130, the movable mirror 70 rotates in the upward direction (toward the exposure retracted position), making it impossible to obtain a proper viewfinder observation state. This also causes problems such as the inability of the subject light to properly enter the AF light-receiving element (not shown). Also, of course Nyatsuta Charge Gear 1
40 may also rotate further counterclockwise,
In the worst case, the flat cam surface 141b of the shutter charge cam 141 and the roller 15 of the shutter charge lever 150
The sliding contact with 1 is removed, and the cam 151 descends to the cam surface 141c.
Correspondingly, the shutter charge lever 150 rotates in the charge release direction (clockwise), and the charge lever 302 of the shutter unit 300 becomes disconnected from the tension before the vehicle travels, reducing the impact resistance performance of the shutter unit 300. This may cause problems. [Step 206] The first motor Ml is energized again in the normal rotation direction. As a result, the mirror drive gear 120 rotates clockwise again, and the movable mirror 70 rotates by sliding between the mirror drive cam 12+ and the mirror drive lever 130.
mirrors up once and then continuously mirrors down again. Further, the shutter churn gear 140 also rotates counterclockwise again, causing the shutter charge lever 150 to rotate in the charge release direction and charge rotation. However, even if the shutter charge lever 150 is rotated again in this state, the shutter unit 300 will not be adversely affected at all. [Step 207] With the re-operation of the first motor N11,
Wait for at least 15 milliseconds, which is the time required for the brush 122 shown in FIG. 4 to deviate from the motion end detection pattern 162 (non-sliding). [Step 208] Mirror drive (shutter charge)
The timer #2, which counts the energization time of the first motor Ml, is restarted. Then, go back to step 136 and step 13.
Repeat steps 6 and below. [Step 153] Display data is sent to the DR of the display driving IC to indicate that one frame has been wound and the normal operation of the gloss charge has been completed, and the process branches to step 22 to end the process. [Step 154] Flag A, which is a flag for storing the previous state of input port P9, is checked. When flag A is 0, the state of the previous input port P9 is memorized as the switch-on state, and when flag A is 1, the state of the previous input port P9 is memorized.
The state of 9 is memorized as the switch-off state. As mentioned above, the signal input to the input port P9 is a signal that is linked to the sprocket 402, and is a signal that is turned on and off multiple times (for example, 12 times) while winding a uniform amount of film. If the OFF signal is repeatedly input, the microcomputer MC2 determines that the sprocket 402 is rotating, and if the repeated ON/OFF signal is stopped, the microcomputer MC2 determines that the sprocket 402 has stopped. In step 154, when the flag A is 1, the process branches to step 157, and when the flag A is O, the process branches to step 155. Immediately after the feeding sequence operation, flag A is set to 0 in step 132, so the process branches to step 155. [Step 155] The previous state and current state of input port P9 are compared. If there is a change, the process proceeds to step 156; if not, the process branches to step 161-\. [Step 156] Since the input state of input port P9 has changed, flag A is newly set to 1. [Step 157] Similar to step 156, compare the previous state and current state of input port P9. If there is a change, proceed to step 158; if not, proceed to step 16.
Branch to 1. [Step 158] Since the input state of input port P9 has changed, flag A is newly set to O. [Step 159] Count the energization time of the second motor M2 and restart the timer #l from the beginning. [Step 161] Since there is no change in the input port P9, the energization of the second motor M2 is started. Check the timer that is counting the time, and if there is no change in the large capacity for 350 milliseconds, it is determined that the sprocket 402 has stopped, and the process proceeds to step 167, where the time of 350 milliseconds has not yet elapsed. The time goes to step 162. [Step 160] Since the input state of the input port P9 has changed, the memory F storing the number of times the on/off switching signal of the input port P9 has been switched is incremented. [Step 162] The previous state of the input port PIO is memorized (check the flag C). When the flag C is 00, the previous state of the input port PIO is memorized as the switch-on state, and the flag C is When it is 1, the previous state of the manual port PIO is memorized as the switch-off state.The signal input to the input port PIO is a signal linked to the sprocket 402, and indicates that the winding corresponding to the film uniformity has been completed. The switch is turned on at this point.The switch is turned off immediately when winding of the next film frame starts, and it is turned on again when winding is completed.Therefore, by detecting this signal, the microcomputer MC2 turns on the film frame. Winding control is possible.In step 162, when flag C is 1, the process advances to step 165.
When flag C is O, the process branches to step 163. Immediately after the winding operation, the flag c-t- is set in step 134.
Since it is set to o, the process branches to step 163. [Step 163] The previous state of input port PIO and
Compare with the current state. If it has changed, step 16
If there is no change, the process returns to step 136 to continue detecting mirror down and winding completion. [Step 164] Since the input state of the input port PIO has changed, the flag C is newly set to 1. After that, return to step 136, mirror down (shutter charge completed)
and continues to detect the completion of winding. [Step 165] The previous state of input port P10 and
Compare with the current state. If it has changed, step 16
6, and if there is no change, return to step 136. [Step 166] Since the signal of the manual port PIO has been switched from OFF to ON, it means that uniform winding has been completed, the second motor M2 is de-energized, and the film counter is incremented. [Step 167] When the first motor M1 is energized, the process branches to step 1.68, and when it is stopped, the process branches to step 169. [Step 168] Check the flag E, which is a flag that stores the voltage level. If the voltage is high, proceed to step 169; if the voltage is slightly low, the motors Ml, M2
The process returns to step 148 in order to stop the simultaneous energization of . [Step 169] Stop energizing motors Ml and M2,
Proceed to the rewind sequence described above. [Step 175] Flag Z of E''FROM is checked to determine whether automatic rewinding is to be performed or prohibited. If flag Z is 1, automatic rewinding is performed, so the process branches to the rewinding sequence described above. On the other hand, if flag Z is O, automatic rewinding is prohibited, so the process branches to step 22. The above is the sequence flow for simultaneously performing release, film feeding, shutter charging, and mirror drive.Next, the lens microcomputer MC3 Flowchart 1 will be explained. FIG. 14 is a flowchart of the lens side microcomputer MC3. [Step 170] Communicate with the camera side microcomputer MC2. [Step 171] The communication result with the camera side microcomputer MC2 is sent to the camera. It is determined whether or not it is an aperture drive command from the side, and if it is determined that it is an aperture drive command, the process branches to step 172; otherwise, the process branches to step 173. [Step 172] The third aperture blade drive command motor M3
is energized in the normal rotation direction (counterclockwise in FIG. 10) to narrow the aperture to a predetermined position. Since the aperture value is sent from the camera during communication, it is only necessary to turn on the power for a period corresponding to the aperture value. Alternatively, a stepping motor or the like may be used as the third motor M3 to output a predetermined number of drive pulses. [Step 173] Determine whether the communication result with the camera side microcomputer is an aperture open command from the camera side. If it is determined that it is an aperture open command, proceed to step 174; otherwise, return to step 170. , camera side microcomputer M
Waits for the next command from C2. [Step 174] Third motor M3 for driving aperture blades
is energized in the reverse direction (clockwise in FIG. 10) for a predetermined period of time, and the aperture is opened. Thereafter, the process returns to step 170 and waits for an instruction from the camera side microcomputer MC2. The above is the flowchart of the lens microcomputer MC3. Here, an outline of the camera sequence in the case of normal operation in this embodiment will be described. Load a new film cartridge 50 into the camera,
Autoloading starts by closing the back cover 430. That is, first, the second motor M for winding
In this state, both the spool 401 and the sprocket 1102 are rotated using the second motor M2 as a driving source, and the film league portion 56 is sent to the spool 401 and wound. Thereafter, the second motor M2 is once reversed, the clutch is switched, the sprocket 402 is freed, and the drive is switched to the spool drive. Then, the second motor M2 is rotated in the normal direction again for about one frame, and it is checked whether the autoloading is successful. That is, if the sprocket 402 is rotated by the film 52 by rotating the spool 401 in a sprocket-free state, it can be confirmed that the leader portion 56 of the film 52 is wound around the spool 401, and autoloading is successful. I can judge what happened. Up to this point, the film feeding operation for autoloading has been completed, the rotation of the second winding motor M2 has stopped, and the camera is in a standby state for the next release operation. By operating the release button 12, the first motor M1 for mirror drive and shutter charging rotates forward by a predetermined amount, moves the movable mirror 70 up (to the exposure retracted position), and puts the camera unit 300 into a charging release state. The charge lever 30 inside the unit, which until now had a tensioning function to prevent the shutter from moving incorrectly,
2 to release the tension. At the same time, the third motor M3 for driving the aperture is rotated forward by a predetermined amount to perform the aperture narrowing operation to the set value. and,
The leading blade group 3 is energized by energizing the coil 383 of the leading blade control electromagnet.
52 is run to start exposure, and after a set number of seconds, the coil 389 of the trailing blade control electromagnet is energized to run the trailing blade group 351 to end the exposure. After the completion of exposure is confirmed, the first motor M1 is rotated by a predetermined amount again in the same direction as the mirror up, the movable mirror 70 is moved down (to the viewfinder observation position), and the shutter unit 300 is closed. Charge is driven, and at the same time, the charge lever 302 for preventing erroneous shutter movement is held at the tension position. Also, at about the same time, the second winding motor M2 is rotated in the forward direction by one frame. Furthermore, the third motor M3 for driving the fringes is reversed to return the diaphragm to the open state. In this state, wait for the next release operation. Then, when the exposure operation based on the above-mentioned release operation is repeated and all the frames of the film have been photographed, the film 52 is stretched when the film 52 is wound, and in this state, the rotating board 420, which rotates in conjunction with the sprocket 402, stops rotating. If detected, the first motor M1 for driving the mirror and charging the shutter is rotated in the normal rotation direction until the mirror is down and the shutter charging is completed. Then, after the second motor M2 for hoisting is stopped,
The rotation is reversed to disconnect the transmission system between the second motor M2 and the spool 401, freeing the spool 401 and reducing the unwinding load. The first motor Ml used for the mirror drive and shutter charge will now be reversed, and the transmission system of the first motor M1 will be changed from the conventional mirror drive and shutter charge transmission system to the rewind transmission system. Then, the rewind gear 201 of the rewind transmission system is rotated in the rewind direction. At the end of rewinding, film 5
When only a portion of the film leader 56 is slightly protruding from the film cartridge 50 in order for all of the film 2 to return to the film cartridge 50, the driven rotation of the sprocket 402 by the film 52 stops, and based on this detection, the first motor The camera sequence ends by stopping all operations including M1. A characteristic feature of the above-mentioned embodiment is that when the blank feed for autoloading is not performed normally, that is, when failure is detected (branching from step 36 to step 37-1), the film is rewound. Since the first motor Ml, which also performs
Even if the planetary gear 105 (see FIG. 5) meshes with the rewinding gear 201 as a rewinding transmission system due to a shock or the like, and the empty feed fails due to this, the film 52 (
The film cartridge 50) can be easily removed, and there is no problem in empty feeding for the next autoloading. (Effects of the Invention) As explained above, the present invention has the following features: An autoloading failure may result in the planetary clutch incorrectly switching to the first
To provide an electrically driven camera that allows film removal even if the problem occurs due to a connection between the motor and the film rewind transmission system, and that does not interfere with the next automatic loading. can be provided.
