Abstract

PURPOSE:To simplify the constitution of a motor-driven take-up camera and to facilitate work and adjustment, by turning a motor forward after rewinding a film, and stopping the motor in the state of a frame feed switch is turned off. CONSTITUTION:When a release lever is pressed down, a shutter operates, then the frame feed switch S4 is turned on, when the film is advanced by one frame, the frame feed switch S4 is turned off. The motor M1 turns while the frame feed switch S4 is on; the film is taken up by the forward rotation of the motor 1, and rewound by the reverse rotation of the motor 1. The film is rewound during the reverse rotation of the motor without operating the frame feed switch S4 and the forward rotation circuit of the motor is formed a specific time after the feeding of the film is completed during the rewinding operation; when the frame feed switch S4 is turned off during the forward rotation of the motor, the motor 1 stops.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric winding camera that winds and rewinds film using a motor. This relates to a camera that has been improved to stop.

In an electric winding camera, the frame advance switch is turned on in succession after the 7-shot release, and while the frame advance switch is making 14 rotations, the motor rotates to advance the film 1.
By pressing the rewind button 7 after winding up a frame, or when it detects that the film has stopped running, the motor will automatically reverse 1. Fill 1 is not rewound. The frame advance switch is used to detect that the film has not been transported at a constant rate, but in order to prevent filtration, advance, and shutter setting from being carried out in a constant sequence, the shutter set button is used to 1ViI] 4-. When rewinding the film, the shutter is turned off (-), so the frame advance switch is not activated.In general, when rewinding the film, );l・``!- This is done when the film cannot be pulled out from the frame, and in most cases it occurs in the middle of the first and second rolls, so it is necessary to turn on the frame advance switch. In this case, the frame advance switch is used as the motor's single source switch, so even if the rewinding is completed and the motor is turned 1 to 1, the motor control circuit remains unchanged. It becomes energized.

To prevent the motor from reversing and stopping + l = at the same time, the inch for frame feed l) is turned on + l -, 'U', 'N.
At the end of the motor reversal period, the -1 fit mechanism of the ivy is converted to the forward rotation state, the shutter is activated ten times, and the reversal of the motor is stopped when the frame advance switch is turned off. I have a camera. This camera has a driven sprocket that engages with the film perforation and rotates at 1-7, and this driven sprocket rotates the entire set.

During the unwinding of the film 13, the tensile force of the film 13 is not applied.
The driven sprocket rewinds and slides to position 1 and 1'.
) Since the interlock with J, T/Yatsuta is cut off, the shutter G' will not be set and the frame advance 111 switch will not be activated.

When the rewinding of the film is almost completed, the filter is removed from the driven sprocket, so it returns to the neutral position and acts to transmit the rotational force of the motor to the seventh gear via one idle gear. Therefore, although the motor is in reverse rotation, the /Yatsutasenoto mechanism is in a forward rotation state and outputs 7 Yatsuta and 1 Sera. When the frame feed switch is closed, the motor stops rotating in the reverse direction]1-. Only 1
7. In this camera, in addition to using the driven shutter I3 as a power source for the shutter, it also detects the slight /r negative load on the film and detects when the film is loaded L (, -11).
-1 The winding system and the shutter are connected, and at the end of the rewinding, the rewinding system and the shutter are connected. 4-7) Is it used as a clutch? C) The structure is complicated. The present invention solves the above-mentioned four drawbacks, such as requiring high-precision processing and adjustment as well as high-precision processing and adjustment. The present invention provides an electric winding camera in which the motor is stopped and rotated when the motor is turned off.

Hereinafter, an actual M11 example of the present invention will be explained in detail with reference to the drawings.

The first “(eye)” shows the camera mechanism, and the line of fire is the officer.
The dotted line indicates forward rotation, and the dotted line indicates reverse rotation. Vol.'-gelj, +
At i, the motor 1 rotates in the forward direction, and through the friction clutch 2, the take-up reel → is rotated. The rotation of the 3-wheel drive unit 5 rotates in conjunction with the shutter center cam 6, which adjusts the gloss, and the shutter set cam 6, and moves the frame forward. The signal is transmitted to the control cam 7 that controls the on/off of the switch.
The same rotation of IT is transmitted to the film 1 and counter 8, and the scale plate is rotated by 1 bit each time the film is transferred by 1 frame.When the film is rewound, the motor 1 is reversely rotated, and the winding IJ -Q is transmitted to the counter 8. 3 in the opposite direction, the reversing clutch 9. Frixicono clutch 101 rewind shaft 1
1, the cartridge 12 can be rotated and the film can be rewound into the cartridge 12. Too bad, when rewinding, the motor 1 is disconnected and the drive slot l-
5 is reversed as the film is transferred, the shutter set cam 6, control cam 7, and film counter 8 are also reversed.

Figure 2 shows the rotation of the motor during rewinding.By pressing the 21 rewind button and by detecting that the film transport has stopped, motor 1 is reversed to rewind the film. Then, while the first frame of the film is being rewound from the shooting position into the cartridge 12, the reverse rotation of the counter 8 is prevented. When the return is completed, the normal rotation circuit of the motor 1 is automatically changed to bψ, and the motor 1 starts rotating in the normal direction when the frame feed switch is turned off.

B) Open the back cover to avoid taking out the r+-ne 12.
For example, the 1 series city of the film counter 8 is divided by 7 and the scale plate returns to the start frame rSJ. X4? When the camera back is closed after loading the L-shaped frame, the motor 1 automatically winds up 17.3 frames of iE rotation onto the take-up reel 3, and the first frame is moved to the shooting position lK11. Motor 1 stops in the set state. After this, the shutter will rotate every time you press the 7 button and release the shutter.
Roll up the normal rrum piece by rl piece? rt Figure 3 shows the film counter and shutter setting mechanism. Gear 2 at the upper end of the tin rocket shaft 20
1 is attached, and the gear 21 rotates together with the driving seat 1j and the keg 5. This rotation of gear 21 is caused by gear 2
2 to the gear 23, and rotates the intermittent feed shaft 24 provided integrally with the gear 23. These gears 22.2
3 is supported by a counter feed lever 25 that pivots about the sprocket shaft 20 as a fulcrum.

The intermittent feed shaft 24 has a notch shaped like a 7, which meshes with the mold wheel 26 so that one rotation of the intermittent feed shaft 24 can rotate the mold wheel 26 by one tooth. When this model wheel 26 rotates by l pitches against the return spring 27, the scale plate 29 connected via the shaft 28 also rotates.
The number of frames to be photographed is displayed from the scale that matches the index 30.

Sliding brushes/32, 33 of the idle feed switch 81°S2 are attached to the lower surface of the mold wheel 26.
move with The sliding brush 32 contacts the contacts 35a and the common contacts 35b on the substrate 34, and the sliding brush 33 contacts the common contacts 35 and 350. This jump feed switch S1゜S2 starts from the start piece I-SJ.
It is turned on during the section in the middle of winding when the first frame is transferred to the shooting position (f:).

On the way to return the first piece to Patrone, Fuishin, counter 8
In order to engage 11-, an inverted 11-claw 37 is provided on the scale plate 29, and this non-return claw 37 engages with a pin 38. The reason why the film counter 8 is locked in the middle in this way is that in order to turn off the frame advance switch, it is sufficient to rotate the motor 1 in the forward direction for one frame after the rewinding is completed. In the example, air transport 11 J1
1 switch S1. Since S2 is connected in parallel with the frame advance IF switch, if the film counter 8 returns at the start frame rslt, the motor 1 will rotate forward when three frames have been transferred, and the This is because it leads to waste.

The engagement IF lever 39 to which the pinot 38 is attached comes into contact with the vertical piece 40a of the counter return lever 40, and a spring 41 is hung between them. The counter return lever 40 is linked to the back cover of the camera.
When the back cover is closed, it is pushed in the direction of the arrow, rotates counterclockwise against the spring 42, turns on the back cover switch S3, and moves the pin 38 so that it touches the outer periphery of the scale plate 29. do. Conversely, when the camera back is opened, 1η114
Rotate the locking lever 39 clockwise around 3,
Without removing the pin 38 from the check claw 37, turn off the back cover switch S3.

The counter return lever 40 and the counter feed lever 25
are connected by a spring 44, and when the back cover is closed, the counter feed relay is activated around the tin rocket shaft 20.
-25 rotates counterclockwise to engage the intermittent feed shaft 24 with the mold wheel 26.

Conversely, when the back cover is opened, the counter feed lever 25 rotates clockwise, and the engagement between the intermittent feed 1IllI24 and the mold wheel 26 is released. Note that when the check claw 37 and the pin 38 are engaged and the rotation of the scale plate 29 is prevented, the counter feed lever 25 rotates in the clock direction, and the intermittent feed shaft 24 is moved toward the mold wheel 2.
You can escape from 6.

A capacitor 77 and a resistor 78 are connected in series between the connection point Q and the frame feed switch S4.The connection point between the capacitor 77 and the resistor 78 is connected to the + side input terminal of the conhaler tough 9, and the resistor A connection point between 80 and 81 is connected to one input terminal. This forward/reverse switching timer circuit is to prevent the forward rotation relay 76 and the reverse rotation relay coil (hereinafter simply referred to as the reverse rotation relay) 82 from being energized at the same time, and is used to prevent the forward rotation relay 76 and the reverse rotation relay coil (hereinafter simply referred to as the reverse rotation relay) 82 from being energized at the same time. , is activated when the frame feeding switch 84 is operated,
When the output terminal A of the comparator 79 is inverted from 1[('' to [L-1), 11JI is caused to occur for a sufficient time for the forward rotation relay switch S6 to switch from contact A to contact A. In this case, forward relay switch S
When 6 is connected to contact a, the forward/reverse switching timer circuit becomes inactive, so the output terminal r r of the conoperator 79
′ of dj is 1. It also operates when the forward H+ relay switch S6 switches nine times from contact O to contact O to rewind the film, thereby delaying the conoparator 79. After this delay, the output terminal of the comparator 79 is set to "L" and the reverse relay coil 82 is connected.
Then, switch the reverse rotation relay isobu-87 to contact a.

A transistor 83 is connected in parallel with the comparator 77, and its base is connected to the reverse relay switch S7. This transistor 83 is turned on when the reversing relay switch S7 is connected to the contact point,
The comparator 7 is turned off when it is connected to contact a, and while the motor 1 is reversing, even if the frame feed switch S4 is on.
This is to prevent the output terminal 9 from becoming F-L J.

The connection point C between the resistor 84 and the capacitor 85 is connected to the + side input terminal of the conoparator 86, and the connection point C between the resistors 87 and 88 is connected to the one side input terminal. This reversal timer circuit G is activated when the reversing relay switch S7 is connected to contact a to form a reversing circuit for the motor 1, and the capacitor 85 is continuously charged and the heavy pressure at the connection point C is connected. The comparator 8 is set only during the time that the pressure rises at point J

A transistor 89 is connected in parallel with the content 85, and the pulse signal of the differentiating circuit 9o causes the 4-7 L
, Reset the reversal timer circuit during film rewinding. For example, a lamp yacht multivibrator is used as the differentiating circuit 9o, and is activated to output a pulse signal when the filter transfer signal generated from the filter transfer detection switch s8 falls. This film transport detection switch S8 is provided with a driven subblock that engages with and rotates the bar fore rayon of the filter.
It is turned on and off by a bottle provided on this driven sprocket. A lamp 91 is connected to the output terminal of the differential circuit 90.
is connected and flashes while the film is being transferred.

The comparators 79 and 86 are open collectors, and when either one is at [-L], the reversing relay 82 is energized. Comparator number 79 is reversing relay 8
The comparator 86 is used to regulate the start of energization of the motor 2, and the comparator 86 is used thereafter to reverse the rotation of the motor 1 and rewind the film into the cartridge.

Switch S9 is a rewind switch, and is used to rewind from the middle of one film.

Turn on this rewinding switch S9 and turn on the reversing relay 8.
When 2 is energized, the reversal timer circuit is activated, so the motor 1 will continue to rotate in reverse even if it is not held down.

Switch the forward rotation relay switch S6 from contact to contact a. On the other hand, since the reversing relay 82 is disconnected, the reversing relay switch S7 is connected to the contact point S7.

When motor 1 rotates forward, 1. The rumble rocket 5 and the take-up reel 3 wind the film in one turn.

At the same time, shack set cam 6 and control 'fT
7 rotates, but since the shutter is set during normal rotation of the motor 1 for rewinding and overtaking, the shutter set lever 51 appears to swing in the direction I4.

The frame feed switch S4, which is interlocked with the control cam 7, also moves the film by one frame at 10K A, but since the jump feed switches S1 and 82 are open, the motor 1 continues to move. It rotates and winds up three flying pieces.

When the first frame is pulled out of the cartridge and transferred to the photographing position, the blank feed switch S1 is activated during this process. ．． S
However, in the middle of winding, the frame feed switch S4 is set to "/", so the motor 1 continues to rotate. When the first frame is transferred to the photographing position, the control lever 48 is rotated counterclockwise to turn off the frame advance switch S4. When this frame advance switch S4 is turned off, TliH is no longer applied to the comparator 73.

When the filter 1 is transferred, the pulse signal is sent from the differential 1 (1j path 9o) while the transfer detection switch s8 repeats the operation without interlocking with the driven sugroknoto. When the bow is output, the 9I light on the top of the camera body will flash to indicate that the film is being fed normally.

is locked to the glossy release lever 57.

When the film is transferred by one frame, the control cam 7 and the control lever 48 turn off the frame feed switch S4, and the normal rotation of the motor 1 is stopped.

At this time, the number "2" on the scale plate 29 matches the index 3 degrees (σ), and the shooting is completed by performing a 7-way release.・Roll up one frame and press the shutter on Nb゛)・1ro.

Since the rotation is stopped by 7σ, the frame advance switch S4 is opened for one moment, and the capacitor 72 is charged during that time. And the time it takes to wind up one piece is T'' = the time it takes to wind up one piece t1
When the voltage at point A exceeds the voltage at point B, the comparator 73 is reversed and its output terminal becomes "I", the forward rotation relay 76 is cut off, and the motor 1 stops.
Ru. In this case, since the frame feed switch S4 is on, when the forward rotation instep relay switch S7 leaves contact point a, the potential at point Q becomes ten. L to this, comparator 7
9 is in the operating state, and after a sufficient time has elapsed to connect the forward rotation relay switch S6 to the contact point, its output terminal becomes rLJ. When the output terminal of the comparator 79 becomes rLJ, the reversing relay 82 is turned on, and the reversing relay switch 87 is switched from the contact a to the contact. Since a reversing circuit is formed, the motor 1 automatically starts reversing, and at the same time 11N, the comparator 86 becomes operational and its output terminal becomes "Ll".

In addition, since the transistor 83 is connected to the terminal R connected to the contact point of the reversing relay switch S7, the capacitor 77 is discharged S1, and the output terminal of the comparator 79 is connected to the terminal R.
11 J. However, since it is an open collector connection, the reversing relay 82 is maintained in the energized state by the comparator 86.

When the motor 1 reverses, the spool of the cartridge 12 is rotated by the rewind shaft 11, and the film is rewound onto the cartridge 12. During this rewinding, a pulse signal is output from the differentiating circuit 90, turning on the transistor 89,
The capacitor 85 is discharged at regular intervals, and the lamp 91 is blinked to indicate that the film is being rewound. It's time to rewind. As the drive sprocket 5 is reversed as the film is transferred, the shutter set cam 6 and control cam 7 are reversed, and the film counter 8 is also reversed.
, J-ru. This shutter set cam 6 is reversed and
Due to the clutch function of the lever 52, the shutter set lever 51 does not follow the shutter set cam 6. Therefore, since the shutter drive lever 54 is in the charge release position and pushes the control lever 48, the frame advance switch S4 remains on, and the control cam 7 simply rotates in the reverse direction.

When the first frame is rewound from the photographing position into the cartridge 12 and reaches the culm A, the bin 38 engages with the check claw 37 and the film counter 8 is prevented from returning.

A scale plate 29 is located between the numbers "1" and "・" on this 11, and a jump switch 81. S2 is on. Note that after the scale plate 29 is locked, the counter feed lever 25 can rotate clockwise against the spring 44, so the intermittent feed shaft 24 rotates while escaping from the pawl width 26.

Even after the film and counter 8 are locked, the motor 1 rotates in reverse to rewind the film. Then, when the film σ rewinding is almost completed, the -7 oration is removed from the driven sprocket. Since the differential circuit 90ii no longer outputs the pulse signal, the lamp 91 stops blinking, and
Transistor 89 turns off. Capacitor 85 is charged with an approximately constant current, and when the pressure at point C exceeds the voltage at point D, the output terminal of comparator 86 becomes r.
The state becomes HJ, and the reversal relay 82 is cut off.

When the reverse rotation relay 82 is cut off, the reverse rotation relay 87 is switched to the contact side, and the reverse rotation of the motor 1 is stopped. However, since the frame feed switch S4 is on, the output terminal of the comparator 73 becomes "L", energizing the forward rotation relay 76 and switching the city rotation relay switch S6 to contact a. As a result, the motor 1 rotates in the forward direction, rotating the shutter set cam 6 and the control cam 7, and also operating the film counter 8. The shutter is set by the normal rotation of the motor 1, and when the frame advance switch S4 is turned off, the motor 1 stops.
The number "1" on the scale plate 29 appears.

In the present invention having the configuration described in (1), after the film has been rewound, a forward rotation circuit for Tanabata is formed so that the motor is rotated in the forward direction at the time when the switch for frame advance 1) is turned off. C), Utilizing the film load of the driven sprocket) 11 Switch the rotation direction of the control/rm using the conventional 4ε position,
(19 formations are in the cylinder and 4C.) There are advantages such as the need for advanced machining to obtain delicate movement of the secondary sub-block, and the need for nl and 1 adjustment.
