Camera for information-bearing films

The present invention relates to a camera for films on which there are information signals indicating the classification of the film or the like.

To enter information such as B. the film speed, To enter the length of the film, the classification, etc., the photographer previously had to take preparatory measures meet the z. B. consisted of the film speed dial or set the picture number notice board or part of the empty film packaging in the holder behind to be attached to the rear flap of the camera so that the photographer was informed of the number of pictures. Has this been forgotten so either too many exposures were made or possible exposures are given away if the end of the film is not reached at the right time while taking the picture was, or one no longer knew whether a color film or a black-and-white film was inserted, so that the - quality of Recordings suffered from time to time. To counter these difficulties, systems have been developed in recent years to automatically enter film information into the camera. Japanese Patent Publication No. 31539/1980 (U.S, -PS 4024557) shows, for example, a system

in which conductive sections are provided in different patterns according to the type of film in the film magazine, to short-circuit the corresponding connection on the camera side and thereby transferring the information to the camera. In another system, part of the Film magazine has a section which is detected by a detection element on the camera side, whereby the corresponding information gets into the camera. With all of these systems a signal is provided in the film magazine housing, but on the other hand you can think of it on the film itself to provide additional openings in addition to the perforations in order to "read" these openings through the camera.

The invention is based on the object of specifying a camera in which information contained on a film is reliable is transmitted prior to recording in the camera, with effective use of the transmitted information is made. ■

The solution to this problem is given in claim 1.

FIG. 1 shows a film pulled out of a film magazine FM with information openings which are shown fully extended. The film F has perforations P over its entire length on the opposite side edges, and in the film there is between the x-th perforation Px after the first perforation P ^ on one side edge of the film and the (x + i) -th perforation I ? x + 1, a film information signal H is formed up to the (x + n) -th perforation Ρ _{χ + η, which film information such.} B. the film speed, the number of pictures to be photographed (e.g. 12, 20, 24 or 36 pictures), the range of intensities (latitude), color sensitivity and so on. This information signal H is between. Perforations P and the film edge are provided, and it has openings hQ formed between adjacent perforations and portions without holes, i.e., provided between adjacent perforations, which are indicated by dashed lines in the drawing (hereinafter the latter are also referred to as non-openings ). Openings hQ are always present at the opposite ends of the information signal H. The film information described above is represented by a combination of such openings h _Q and non-openings h ^. The first single image (frame) F _{1 of} the film F begins at the η-th perforation, calculated

from the umpteenth perforation. On one side or the other of this single image F ^ a preprinted symbol "No. 1" indicates that this is the first single image. After the last frame of the film, for example after the 36th frame, calculated from the first frame F ₁ , an end-of-film signal he, which identifies the end of the film, is formed as film information similar to the information signal H.

Figure 2 shows a first _; Embodiment of the invention in a single-lens reflex camera. The shaft of a motor M is connected to a drive shaft 56 via a final reduction gear and slip mechanism 2 for excessive torque. A one-way clutch disc 3 is attached to the upper portion of the drive shaft 56; the drive shaft 56 extends through the motor M and has a one-way clutch pawl plate 88 attached thereto at its lower end form so-called one-way clutches. If the motor M rotates in the direction indicated by a solid arrow in the drawing, a pinion 5 attached to the ratchet plate 3 ″ rotates in the direction of the arrow, but this rotational movement is not transmitted to the pinion 89 . On the other hand, turns

the motor turns in the opposite direction the pinion 89 in the direction of the dashed line Arrow, this rotary movement is not transmitted to the first pinion 5. These one-way clutches can also be equipped with another, conventional mechanism, for example with a cam and a Role.

A phase clutch disk 7 is attached to a second pinion 6 constantly meshing with the first pinion 5 and has the same number of grooves 7 ¹ as a toothed drum 11 has teeth 11 '. A vertically movable phase coupling 8 is loosely seated on the upper shaft 72 of the toothed drum, and the rotation of the upper shaft 72 of the toothed drum can be transmitted by a mechanism not shown. The clutch disc 7, clutch 8 and an integral clutch pin 8 'together form a phase clutch, and when the pin engages a groove 7', a toothed drum shaft 81 and the upper shaft 72 of the toothed drum are moved together. A compression spring 34 provided between a flange 72 'of the upper shaft of the toothed drum and the clutch 8 biases the clutch 8 in one direction in order to maintain the engagement between the pin 8 ¹ and the groove 7 ^f , ie, the bias takes place after below.

This phase clutch can be released by pressing a rewind button 106 provided under the toothed drum 11 upwards, whereby a shaft (not shown) provided in the toothed drum shaft 81 is raised and the clutch 8 is pushed upward to remove the pin 8 ¹ from the To solve groove 7 '. A coupling 103 provided for multiple exposure under the second pinion 6 sits loosely on a shaft 6a fastened to the second pinion 6 and, even if this is not shown in detail, is displaceable in the vertical direction with respect to the shaft 6a and with the rotation of the shaft 6a rotatable. In the position shown, this coupling 103 transmits the rotation of the second pinion 6 to a pinion 104 due to the engagement of a pin 104 'of the pinion 104 in a groove 103 ", and when the coupling is moved upwards, there is no longer any engagement, so that even if the pinion 6 rotates, the pinion 104 does not rotate. The pinion 104 is mounted on the shaft 81. A multiple exposure setting lever 110 is movable about a shaft 121, and when an setting knob 109 is moved upward, a flange 103 'becomes the Coupling 103 is pushed upward by the central portion 110 'of the adjustment lever 110, thereby releasing the coupling 103. A retaining lever 122 is rotatable about a shaft 124 and is biased by a spring 123 so that when the coupling 103 the position shown, the lever 122 rests against the outer circumference of the flange 103, while when the coupling 103 upwards

is moved, the lever 122 comes under the flange 103 'and the coupling 103 in the released position holds. If the second pinion 6 rotates in the direction of the arrow, the holding lever 122 is due to the friction between the underside of the flange 103 'and the surface of the end 122' of the retaining lever 122 outwards in Pushed towards the outer circumference of the coupling 103 and can thereby return to the illustrated non-holding position.

On the upper portion of the toothed drum 11 are a first Film counter drive gear 78 and a generator 25 are fixed, and inside the sprocket is one not shown Rewind clutch is provided, and when the rewind button 106 is pushed up, the sprocket 11 and pinion become 104 released, so that only the toothed drum 11 is freely rotatable. Around the rewind button 106 is a rewind hold lever 107 arranged, which works very similarly to the holding lever 122 when holding and releasing. The release of lever 107, however, must be quick and therefore the underside of flange 106 'of button 106 is knurled.

A sensor 26 is arranged opposite the generator 25, and these two elements together form one Pulse generator that can generate the same number of pulses as there are teeth on the toothed drum, es namely the same number of pulses is delivered as

Go through perforations when transporting the film. If this generator 25, for example, with the same number Provided by convex portions is how teeth are provided on the toothed drum and a magnetic material is provided on the convex portions to magnetize them, and when the sensor 26 is formed as a coil is, the rotation of the gear drum can be detected as a fluctuation of an electric current. Alternatively the sensor 26 can be a Hall element, and the rotation can be detected by a change in voltage. An idler gear 19, an intermediate gear 20 and a coil gear 21 always form a gear train, which with the Toothed drum pinion 104 meshes, and a spool 10 is mounted on the spool gear 21 via a friction mechanism 22.

A second gear 29 continuously meshes with the first fi rm counter drive gear 78, and rotates in the normal or reverse direction depending on the rotation of the toothed drum a film counter transport shaft 38 moves in a corresponding direction. On the upper section of the transport shaft 38 a feed gear 39 is fixed with a V-shaped groove. Therefore, if a pawl 40 with the gear meshes, a film counter 41 formed in one piece with the pawl 40 moves with one full revolution of the toothed drum by one tooth in the normal direction and revolves in the reverse direction for one full revolution of the toothed drum one tooth back.

A permanent magnet 28 shown on the right in FIG. 2 forms together with a coil 27 a release magnet Mg1, and when the coil 27 is supplied with electric current is, the force with which the permanent magnet 28 an anchor 29 attracts, are temporarily reduced. A release lever 31 is around a shaft 36 on its left End rotatable, and the armature 29 is at one end of the lever attached. When the lever 31 is rotated to the left, it is attracted by the permanent magnet 28 and in the shown position stopped. When the coil 27 is electrical Power is supplied, the lever 31 is through the Turned by force of a spring 30 to the right. On the lower section a release button 17 shown at the top right in FIG. 1 is a main switch SW1 and a release switch SW6. When the operating button 17 is depressed, the main switch SW1 can first be closed, and then the trigger switch SW6 can be closed.

The following is a description of the preparatory measures for a photograph.

The rear flap (not shown) of the camera is opened, the front end of the film F is inserted into a groove 10 ' inserted in the spool 10, the perforations P are brought into engagement with the teeth 11 'of the toothed drum 11, and then the back door is closed. Thereafter, a part (not shown) of the rear flap presses the projection

12 · a locking lever 12, which is shown in the middle on the left of FIG. 2, in order to rotate the lever 12 to the left about a shaft 14 against the force of a spring 13. Thereafter, a protruding part 12 ″ of the lever 12 is withdrawn from the position in which it previously rested against a lever 15 so that the lever 15 can rotate to the left about a shaft 16. When the actuating button 17 is pressed, the main switch becomes SW1 is closed and the motor M starts to rotate in the direction of the arrow, and the speed _f of rotation of the motor M is reduced by the final reduction gear 2 and causes the rotation of the one-way clutch disc 3. The rotation force over-rotates the first pinion 5 the pawl 3 'and the pawl plate 3 "in the direction of the arrow and continues to rotate the second pinion 6, which in turn rotates the toothed drum 11 via the clutch 103 for multiple exposure, the pinion 104 and the toothed drum shaft 81. At the same time, the rotation of the pinion also rotates the spool gear 21 in the direction of the arrow via the idler gears 19 and 20. The gear 21 continues to rotate the spool 10 via a spool friction mechanism 22. In this way, spool 10 and toothed drum 11 are rotated, see above that the film F is transported while it is being wound on the spool 10. On the other hand, closing the main switch SW1 turns on a light source 23 when the information signal H is applied to the film F on the

Position of the sensor 24 arrives at the advancing film, the pulse counter of the circuit is started by the output signal of the sensor. In addition, the with the toothed drum 11 rotated generator 25 and the sensor 26 generates pulses, and the aforementioned pulse counter starts with the counting of these pulses as a function of the output signal of the sensor 24. After a predetermined, The number of pulses corresponding to the first frame on the film is counted, the coil 27 is supplied with an electric current supplied to weaken the attractive force of the permanent magnet 26. Thus, the lever 31 rotates by the force the spring 30 to the right. Now the pin 31 'of the lever 31 comes to rest against one end 32' of a lever 32, to overcome the force of the spring 33, whereby the lever 32 rotates to the right. Therefore the other end becomes 32 " of the lever 32 is offset to the left as shown in FIG. 2 and is released from the underside of the phase coupling 8, so that the clutch 8 by the force of the phase clutch spring 38 lowered and the pin 8 * in a groove in the clutch disc 7 comes down. Since a take-up restriction plate 60 and a restriction lever 59 are engaged with each other the clutch 8 cannot be rotated. As a result, the clutch disc 7 is stopped, and so is the toothed drum 11 and the spool 10 associated therewith are also stopped. Simultaneously with the power supply to the coil 27, the power supply for the motor M is blocked, and the phase clutch disk is stopped no excessive exposure. .

Λ Λ ΙΛ Ο

In this way, the film F is transported a certain distance from the first opening IIqq of the signal H and stopped at a predetermined position with the frame number "No. 1" preprinted on the film. coincides exactly with 'the recording plane for the first single image. That is to say: the first individual image F1 according to the figure is opposite the camera aperture.

On the other hand comes another end 32 "of the holding lever '32 in contact with the pin 35' on a retaining hook in the clockwise rotation described above to the plant and overcomes the force of the spring 36, so that the hook rotates to the left about a shaft 37, thereby engaging between one end 35 "of the hook and the end 15 'of the Release lever 15 so that lever 15 is rotated to the left by the force of spring 36A and a shaft 38 in the same direction as the lever 15 is rotated by means of a hole 15 "in.dem lever 15 and the transport wheel 39 comes into engagement with the pawl plate 40 and is thus ready for the advance of the film counter 41.

Furthermore, a protruding part ^{15'fl of} the lever comes into contact with a protrusion 42 'of an O-display plate 42, which is rotated to the left about a shaft 43 against the force of a spring 44 attached to the upright part of the O-display plate, so that the "O" indicator at the top 42 "of the upright is withdrawn from a position in which it covers the top portion of the film.

- Ti-

Counter 41 covers so that the number "1" is displayed on the film counter. On the other hand, the light source 23 turned on when the main switch SW1 is closed is turned off simultaneously with the power supply to the coil 27. After the sensor 24 detects the first signal aperture hg _Q in the film F, the presence of subsequent similar signal apertures is read and the film speed, the number of film frames, the density of darkness, the color sensitivity, etc. are stored in a memory device which will be described later will. Subsequent to the supply of power to the coil 27, the motor M starts rotating in the opposite direction (in the direction of the dashed arrow) due to the operation of the circuit.

This reverse rotation of the motor M takes place as follows: a switch SW8 for detecting the left rotation of the display plate 42 may be provided to by the left rotation of the end 42 ″ of the display plate 42 to be closed and thus to reverse the direction of rotation of the motor M.

One-way clutch pawls 88, 89 'and a gear 89, the idle during the winding process come into engagement with one another around the gear wheel arranged thereon to rotate and by means of a shaft 95 via gears 96 and 97 a magnetic reset cam 98 to-rotate. As a result a roller arranged at the left end of a tensioning lever 70 is displaced from the plane of the drawing in FIG

■ - 22--

The tensioning lever 70 is rotated to the left about the shaft 46, while an overvoltage spring 71 is also rotated to the left and thus also the release lever 31, which comes to rest thereon, is rotated to the left and causes the armature 29 is attracted by the permanent magnet 28, whereupon the tensioning lever 70 by the spring 73 to the right is rotated and returns to the position shown when the roller 69 'in the small diameter Section of the reset cam 98 arrives. A pin 99 provided on gear 96 now closes one Reverse rotation stop switch SW5 to stop the engine. This is the preparation for a recording closed.

The following describes the operation when taking pictures.

If the release button 17 is pressed when the pulse count of the circuit has reached a count, which corresponds to the first frame, or when the switch SW8 is closed, is activated by closing the release switch SW6 electrical power to coil 27, and the trip lever 32 is around the shaft 36 discussed above Way turned to the right. During, the time the lever 15 is in the preparation of the recording after has been turned to the left, and the end 15 'of this lever is against a pin 49 'at one end of the change lever 49 came to the plant, which in turn by the force a spring 48 was rotated to the right. Consequently will

an end 50 'of a release pawl 50 which against a Pin 49 "rests on the other end of the change lever, pushed so that the release pawl 50 around a shaft 47 mounted on the release lever 31 against the force of a F.spring 101 is rotated to the left and the end 50 "of the release pawl advances to a position in which it is a Pin 51 'can strike at one end of a mirror hook 51. Therefore, the mirror hook 51 is wrapped around a shaft 53 due to the mentioned right pivoting of the lever 31 through the end 50 "of the release pawl 50 to the left and the pin 51 'pivoted against the force of a spring 54, whereby the engagement between the hook part 50 "and the mirror lever 52 is released, so that this lever 52 can move in the direction of the arrow and a fast-pivoting mirror by a mechanism not shown is pivoted upwards; then the shutter is released and a mirror return signal lever is triggered is pivoted to the right about a shaft 105 by a mechanism not shown. A mirror tension lever 55 is moved to the top right according to FIG. 2 in order to act on one end 59 'of a limiting lever 59, so that. the lever 59 around a shaft 56 against the force of a limiting spring 57 is rotated to the left and is released from the groove 60 'of the winding-up limiting disk 60. At the same time, the winding start switch SW2 is turned on one end 59 'of the lever 59 is closed. Continues to return

by the return of the mirror of the lever 52 back to the position shown. This creates a photography cycle closed.

A winding process will be explained below.

When the winding start switch SW2 is closed, the motor M starts rotating, and the pinions 5 and 6 rotate in the direction of the arrow, similar to the one above was described in connection with preparations for a photograph; the toothed drum 11 and the spool 10 start spinning to advance the film. On the other hand, the rotation of the pinion 6 rotates the gear via the phase clutch 8, and continues to rotate the tensioning gear 62, which meshes with the gear 61. Consequently the shaft 63 is rotated, and a magnetic clamping cam attached thereon 64 and a locking mirror clamping cam 65 shown in the lower part of FIG. 2 are rotated. The cam 64 causes the lever 70 to rotate about the shaft 46 via the roller 69 to the left. Together so that the overvoltage spring 71 is also rotated to the left in order to come into contact with the release lever 31 and turn it to the left. This causes the armature 29 to be attracted against the permanent magnet 28 whereupon the roller 69 comes to the small diameter portion of the cam 64, whereupon the tensioning lever 70 by the spring 73 to the right is rotated and returns to the position shown.

On the other hand, the rotation of the shutter mirror clamping cam 65 an arm 75 rotated to the left about a shaft 74 via a roller 67 against the force of a spring 68, a pin 76 moving to the right as shown in FIG. Consequently, the rod 77 connected thereto also becomes moved to the right according to Figure 2, and a shutter mechanism and a mirror mechanism are by a mechanism not shown stretched. With the provision of the driving force for the mirror mechanism the mirror clamping lever 55 according to FIG. 2 is moved downward to the left by a mechanism (not shown), releases moves away from the limit lever 59 and is retained by the lever 102. On the other hand, as the winding progresses the rod 77 through the small diameter portion of the cam 65 which abuts the roller 67 comes, moved to the left to return to a position ready for the slide to move and the mirror is, namely in the position shown.

The film counter advances in the following way:

With the rotation of the sprocket 11, the film counter transport shaft becomes 38 rotated via gears 78 and 79 to rotate the feed wheel 39 and the ratchet plate 40 to advance one tooth on a full revolution. While the film is wound up in this way becomes a

Position reached in which the groove 60 'of the limiting disk 60 engages with the limiting lever 59, whereby the winding is stopped. By this coming into engagement, the lever 59 is rotated to the right, and one end 59 'of the lever is withdrawn to the front left (as shown in FIG. 2) so that the winding-up start switches SW2 is opened. Even if the limiting disk 60 is held by the limiting lever 59, it takes place no excessive stress. This completes the winding process.

In this way, take-up on take-up takes place with the winding than one cycle at a time.

Stopping when the end of the film is reached is intended in the following explained.

As already described, the number is photographable Frames on the film, namely the corresponding film length in the circuit 'by the detection of the film information signal H, and therefore when the adjustment of the first frame has been made, namely when the first current supply to the coil 27 is effected, a squaring circuit is reset to perform the squaring the amount of film wound up and the quarter value is compared with the stored value of the

Film length, and if these two values are the same, a release process is prevented, so that even then, when the trigger switch SW6 is closed, no current is applied to the coil 27. The camera is now in a state in which winding is finished.

Rewinding will now be described.

When the rewind button 106 according to Figure 2 is pushed up is, the toothed drum 11 and the toothed drum gear 104 come out by a mechanism not shown Intervention, and the. Rewind hold lever 107 comes against the cylindrical part below the knurled portion 106 ″ of the button 106 due to the force of the spring 80 to rest and stays there. In response to the aforementioned pushing up "of the rewind button 106, the phase coupling becomes 8 according to Figure 2 by a mechanism not shown moves upward within the sprocket shaft 81, thereby engaging between the coupling pin 8 'and the coupling disc 7 is released and the camera is ready for the next film to be inserted. If next the rewind lever 82, which is shown at the bottom left in FIG. 2, is moved to the left by a shaft 83, becomes the rewind switch 87 closed, and the motor M begins to move in the opposite direction as when the

winding (the winding direction is shown by a dashed arrow). Now come the one-way clutch pawls 88, 89 'and the gear 89, which during of the winding process have idled, in engagement with each other, around the gears arranged thereon 90, 91 and 92, and by engaging the pin 93 in a groove 92 'in the upper portion of the gear the rewind clutch 86 is rotated. On the shaft 83 of the A control cam 84 is mounted on the rewind lever 82, and left rotation of the lever 82 causes an upward movement movement of the shaft 85 resting against the control cam 84, so that the clutch 86 assumes a position, in which it engages a slot in the spool of the film magazine. During the time in which the rewind is done in this way, there is no winding due to the operation of the Eiriwegkupplung 3, 3 'and 3 "above the Engine. During this rewinding, the toothed drum 11 is through the. The film is fed back in the reverse direction rotated, whereby both the generator 25 and the first Film counter drive gear 78 are rotated in the reverse direction and therefore from the sensor 26 pulses to the Circuit are given while the film counter 41 is also rotated in the reverse direction to that shown To decrease number. The pulses counted by the backward rotation are counted down to a number, which corresponds to the number of frames which is stored in the circuit and which is wound back into the film magazine must become; then the engine turns into a

Stopped position at which the reverse rotation stop switch SW5, which is shown in the middle on the left in FIG. 2, is closed by the pin 99.

This is to ensure that the positional relationship between the magnet cam 64 and the idler 69 is always as shown when the motor is stopped, so that the reverse rotation of the motor is stopped by closing the switch SW5 in addition to the pulse count . This ends rewinding, and the rewind lever 82 is returned to the position shown. The rewind button 106 is moved outwards because it is rotated in the initial state of the loading of the next film due to the friction between the knurled portion 106 and ^tJ the holding lever 107, and the coupling mechanism (not shown) between the pinion 104 and the toothed drum 11 takes the Engagement position.

Next, the back door of the camera is through a Mechanism not shown is opened and the film magazine is removed from the camera. Now the pressure is on of the locking lever 12 against the .Projection 12 'zero, and therefore, due to the action of the spring 13, the lever 12 is pivoted to the right, and; "the switch control pin 131 is moved "upwards" according to FIG

Back door open / close switches SW3 and SW4 are opened and the information stored in the circuit is cleared. When the lever 12 is pivoted to the right, the lever 15, which up to then has pressed against the upstanding part 12 ", is pivoted to the right, and the hole 15" moves the transport shaft 38 out of the plane of the drawing according to FIG Engagement between the transport wheel 39 and the ratchet plate 40 is released. Furthermore, the O-display plate 42, which has come to rest against the protruding section 15 ' ^f ', is pivoted to the right by the force of the spring 44 until it hits the limiting pin 94, whereby an "O" is displayed again on the outside. On the other hand, in preparation for the insertion of a new film, the end 15 'of the lever 15 is brought into engagement with an end 35 "of the holding hook 35. Furthermore, the pin 49', which until then had come to rest against the end 15 ', rotates the Change lever 49 against the force of the spring 48 to the left, so that the pin 49 ″ is moved to the left according to FIG. 2; the release pawl 50 is moved to the right and the end 50 ″ assumes a position in which it cannot press against the pin 51 'at one end of the mirror hook 51. The above description relates to the explanation of the operation between film loading and exclude film-her.

FIG. 3 shows an embodiment of the electrical circuit corresponding to the first embodiment according to FIG. In Figure 3, elements are shown which correspond to the elements of Figure 2, namely the main switch SW1, the winding start switch SW2, the flap open / close switches SW3 and SW4, the reverse rotation stop switch SW5, the release switch SV / 6, the rewind switch SW ?, the release magnet Mg1 with the coil 27 and the permanent magnet 28, and the motor M. Details of the film information reading circuit 1000 and a digital circuit 1001 are shown in FIG. An exposure setting circuit 1004 sets exposure factors such as exposure control. The aperture value, the exposure time, etc., and it brings the values to an exposure control circuit 1003. A voltage source timer is constituted by transistors Q1, Q2, a resistor R1 and a capacitor C1. A transistor Q3 controls the power supply for the film information reading circuit 1000. A transistor 0.4 is used to secure the power supply for the exposure control circuit during the time when the shutter of the exposure control circuit 1003 is open. A MOS transistor 03 is switched on when its gate connected to the output η of the digital circuit 1001 assumes the Η level. A first voltage source ET supplies

■ '? ■, voltage to all circuit components including the motor, and a second voltage source E2 supplies power only to _a digital circuit 1001, -if the first voltage source is exhausted or when the first voltage source is replaced. The voltage sources E1 and E2 are connected together via back tr oniT blocking diodes D2 and D3 and are connected to the voltage supply connection f of the digital circuit 1001 via the flap open / close switch SW4. A transistor Q6 is controlled by the output g of the digital circuit 1001. When transistor 0.6 is on, voltage is applied to warning circuit 1002 and transistor Q7 is turned on while transistor Q8 is turned off; therefore, when the release switch SW6 is closed, no release signal is applied to the exposure control circuit 1003. When voltage is applied to the warning circuit 1002, a piezoelectric tone generator CV is supplied to emit a tone while simultaneously a light emitting diode LED. flickers to issue a warning.

A transistor Q9 drives a magnet Mg2 to hold of the rear shutter curtain. Transistors Q11 - Q20 together form a motor drive circuit. A MOS transistor Q10 has its gate connected to the terminal k

of the digital circuit 1001 and controls the automatic stop during the Rewind as explained below. The motor driver circuit is designed such that, when transistor Q15 is turned on, transistors Q16 and Q13 are switched on and the motor M rotated in the normal direction to drive the mechanism of the film take-up drive system, and if so a transistor Q11 is turned on, transistors Q14, Q18, Q17 and Q12 are turned on, and the motor M. rotates in the reverse direction to drive the rewind drive system mechanism. When transistor Q15 or Q18 is on, transistor Q19 is turned on, to discharge a capacitor C2 and turn on a transistor Q20, and if both transistors Q15 and Q18 are in the non-conductive state, becomes transistor Q19 is turned off and transistor Q20 remains for a predetermined time determined by a resistor R2 and the capacitor C2, conductive, whereby the transistors Q16 and Q17 are switched on, to energize an electromagnetic brake for the motor M and thereby stop the motor M quickly.

The operation of the circuit shown in Figure 3 ^ is described below:

When the back door of the camera is opened to a To load film into the camera, the flap open / close switches are used SW3 and SW4 open, and there is no more voltage to the digital circuit 1001 given, and even if the main switch SW1 is closed the transistor Q1 is not turned on. Now the take-up start switch SW2 is in its The OFF position and transistor Q3 is also in the OFF state. As a result, no electricity gets to the Film information reading circuit 1000 and exposure control circuit 1003. Rewind switch SW7 is located is now in the OFF position and therefore transistor Q11 is off because of the take-up start switch SW2 is off and the flap open / close switch SW3 is also off, transistor Q15 is also in the OFF state and all of the transistors in the motor driver circuit are in the OFF state. The MOS transistor Q5 is also in the OFF state because no power is being supplied to digital circuit 1001 will. When in this state the back door of the camera is closed after the film and the magazine are set in the predetermined position ", the back door open / close switches SW3 and SW4 closed so that voltage can reach digital circuit 1001.

Details of the digital circuit 1001 are explained below with reference to FIG.

When the digital circuit is closed by closing the back cover open / close switch SW4 voltage is supplied through the resistor R10, a capacitor and ClO a buffer amplifier A1 generates a reset pulse of L level for a certain time. Flip-flops FF1, FF2, Counters C01, C02, Q03 and a data register RG1 become reset by the reset pulse, and the output of FF1 goes low, while the outputs of FF2, C01 and C03 assume Η levels. On the other hand, the Main switch SW1 is not yet closed, and therefore transistor Q1 is not turned on, and the voltage at the connection S is at the L level, so that the outputs of the AND gates AND3 and AND4 are at the L level. Because the output of the AND gate AND4 is at L level, is the MOS transistor Q5 derived from this output is driven in the OFF state.

A digital comparator CP3 provides an output signal Η level decreases when the output signal of the counter C02 matches the output signal of the data register RG1, However, it emits a signal in its initial state. L level, and consequently the output of a NOR gate N0R1 is at Η level, so that the transistor 0.6 is in the OFF state. All of the transistors Q10-Q20 of the motor driver circuit are in the OFF state.

When the release button 17 is next pressed halfway, the main switch SW1 is closed and the transistor Q1 is switched on, so that the terminal S of the digital circuit 1001 assumes Η level, the outputs of the AND gates AND3 and AND4 assume Η levels, the MOS -Transistors Q5 are turned on and transistor Q3 and transistor Q15 of the motor drive circuit are turned on so that power is supplied to the film information reading circuit 1000 while the motor is rotating to start winding the film. At the same time, the output of the NOR gate N0R1 goes low, so that the transistor Q6 is turned on to supply the warning circuit 1002 with voltage, whereby the LED1 flickers and CV generates a tone to indicate that an empty feed of the Films takes place. At this time, the transistor Q8 is in the OFF state, and therefore even if the release switch SW6 is closed, the release magnet MG1 is not energized. _: <

When the film starts to be fed backwards, a film transport pulse for moving the film by a distance corresponding to a perforation through a Magnetic flux change detection coil L1 (see FIG. 4) generated corresponding to the sensor 26 in FIG. 2; this signal will amplified by an amplifier 0P1 and a comparator CP1

and shaped and given to the AND gate UND1. However, the information signal H is not in the beginning portion of the film and therefore no film information pulses are generated and the flip-flop FF1 is in the same state as if it were reset and the AND gate AND1 is closed. The film information detection parts 23 and 24 shown in FIG. 2 comprise a light emitting diode LED2 and a photodiode Ph2 opposed thereto, and when the information opening h _Q in the film passes the film information detection parts, a photocurrent generated in the photodiode Ph2 from an amplifier 0P2 and a Comparator CP2 is amplified or shaped, and a _{pulse corresponding to the film information opening h Q} is transmitted to the digital circuit 1001. When the film advances and the first film information opening passes the detector section LED2, Ph2, a film information pulse is generated and the flip-flop FF1 changes its state so that its output becomes Η level, and the AND gate AND1 is opened. This state is maintained until the rear lid of the camera is opened thereafter, so that the lid open / close switch SW4 is opened.

A film transport pulse generated according to the movement of the film by a piece corresponding to a perforation Open the AND element UND1. is taken from the counters C01, C02

- THU - ■. »......» Z

and C03 counted. The pilm information holes are provided "that a position of a film information hole is determined for a perforation in the film, and therefore the register RG1 stores successive film information consisting of a combination of openings 9Bq and non-openings 9B ^. If the area in which the film information openings are provided, namely a predetermined number N2 of perforations, are counted by the counter C01, the output of the counter C01 assumes the L level, and the AND gate AND2 is closed, and when all of the film information is stored in the shift register RG1, the input operation becomes for the information storage signal ended. However, the counter C03 maintains its high level output signal, up to a predetermined number of perforations accordingly the position at which the first marked recording frame F1 of the film is aligned with the opening of the camera is achieved. As a result, the film continues to be idly fed. When the number of perforations corresponding to the position in which the first individual image plane F1 is aligned with the opening part of the camera, has been counted, the output of the counter C03 assumes the L level, and the output of the AND gate AND4 assumes also at L level, so that that of the output signal of the AND gate AND4 driven MOS transistor Q5 is turned off. By turning off transistor Q5

the transistor Q3 is turned off to the film information reading circuit 1000 disable, and also transistor 015 in the motor driver circuit is turned off so that the transistors Q16 and Q13 are also turned off.

On the other hand, the output of the inverter changes INV2, which is connected to the output of the counter ^ C03, from L to Η level, and the output of the inverter INV3 changes to L level while passing through a resistor R11 and a capacitor C11 is delayed. Consequently takes the output of AND gate AND7 for one predetermined by the resistor R11 and the capacitor C11 set time Η level, and that by the output signal of the AND gate AND7 driven MOS transistor Q21 remains conductive for this specific time to the Release magnet Mg1 of exposure control circuit 1003 to to drive. When the magnet Mg1 is excited as already described, the mechanism of the exposure control system, namely the mirror drive system, does not become operated, but only the clutch mechanism 8 for the film winding system, namely after the release of the film while the movie is loading. The output of the flip-flop FF2 has Η level, the output signal of the inverter INV2 changes from L to Η level, causing the output of AND gate AND6 to operate simultaneously

of the clutch mechanism 8 assumes Η level, and, the transistor Q11 driven by the output of the AND gate AND6 is turned on, and the transistors Q14, Q18, Q17 and QI2 are turned on, so that a current flows in the motor M in the reverse direction, which causes the motor to rotate in reverse. Reverse rotation of the motor M has no effect on the pilm take-up mechanism, but operates the film rewind mechanism, and the rotation of the idler gear in the rewind gear assembly resets the release magnet mechanism in the manner previously discussed. "' ^: ' - ^H *

When the trip magnet mechanism is reset, the reverse rotation stop switch SW5 is closed, and at the output of the AND gate AND5 is a through the resistor R12, the capacitor C12 and the inverter INV1 Set pulse generated, whereby the flip-flop FF2 set and is tilted so that its output signal is now at L level changes. This state is maintained until the flap open / close switch SW4 is opened. Because the output signal of the flip-flop FF2 changes to the L level, the output signal of the AND gate AND6 changes to L level, transistor Q11 is turned off, so that transistors 0.18 and Q12 are turned off, and transistor Q19 will turn off and therefore the transistor will Q20 switched on for a certain time, which is determined by the resistor R2 and the capacitor C2. Therefore, the transistors Q16 and Q17 become for one

switched on for a certain time, whereby an automatic braking acts on the motor M to stop it quickly. In addition, the output signal of the AND gate increases UND3 is now at L level, the output of the digital comparator CP3 remains low and therefore the output goes down of the NOR gate NOR1 Η level, and the transistor Q6 becomes turned off to disable the warning circuit 1002, transistor Q7 is turned off.

Turning transistor Q7 off turns the transistor Q8 on when the transistor controlling the power supply for the exposure control circuit Q1 is in the ON state and hence becomes the trigger switch SW6 closed, whereupon this leads to the case control circuit 1003 is transmitted to enable the shutter release. When the rewind switch SW7 is off is, which is the case in the "photographing" mode, the counter contents of the counter C02, for example in the case of eight perforations, an individual image plane adds eight pulses as a unit, and this counter reading is compared with the frame information 0UT2 stored in the data register RG1 Movie information. The comparison is made by the digital comparator CP3. If the count of the counter C02 is greater than the number of frames, the digital comparator CP3 outputs a signal of Η level. If besides

the rewind switch pSW? is turned on, namely then, when the PiIm is rewound, it switches Counter C02 switches to subtraction mode and effects a subtraction with the value added up to that point as, reference value, and when the count reaches a predetermined value which is determined to be at least the first frame is completely drawn into the magazine and the leading portion of the film is not completely drawn into the magazine, a signal will be generated output with Η level (OUT3).

As described above, after the Film has automatically become exposable at the first frame, the release lock condition is lifted, and a photograph can take place. When the release button is depressed, the main switch SW1 and the release switch Closing SW6 puts power into exposure control circuit 1003 and continues to the release magnet Mg1, and the mechanical sequence in the The camera starts, whereupon from the film information stored in the data register RG1 of the digital circuit 1001 digital signals such as B. Film sensitivity, density, film type, etc., which are necessary for setting of the exposure level is transmitted to the exposure control circuit 1003 to perform exposure control based on of the setting section 1004 for exposure setting factors that differ from the film information

and the light receiving element Ph1. When power is supplied to the shutter magnet Mg2, namely, when the film is exposed, the transistor Q4 is turned on to ensure the power supply to the exposure control circuit 1003. The state of the transistor Q3, which takes over control of the power supply for the film information reading circuit 1000, hangs. only from the state of the transistor Q5 and the winding start switch SW2 due to the presence of the reverse current blocking diode D1. As a result, when the magnet Mg2 is energized, the transistor Q5 is in the OFF state and the winding start switch SW2 is also in the OFF position, so that the transistor Q3 is turned off and the film information reading circuit 1000 is not energized .

If the shutter magnet Mg2 is de-energized, the rear shutter curtain of the shutter is closed, the mirror moves down, and the take-up start switch SW2 is closed. By closing the take-up start switch SW2, power is supplied to the film information reading circuit 1000, and the transistors Q15, Q16 and Q13 are turned on; by normal turning of the motor M take place the winding of the film, the cocking of the shutter, the resetting of the release magnet Mg1, etc. When the winding is finished, the winding start switch becomes SV / 2 opened to stop the motor M,

"", 313359 T

\ ind the power supply to the film information reading circuit 1000 is stopped. The above process is continued until the last one suitable for recording Frame Ff on the film. During film winding, the winding start switch SW2 becomes ON

to the trigger circuit for operating the magnet Mg1 in the exposure control circuit 1003 to thereby preventing the release circuit from operating while the film is being taken up; this will cause a malfunction the release magnet mechanism for the reset process prevented. , ".

When the last frame suitable for an exposure is exposed on the film, the film is wound up and the release magnet is reset and tensioning the closure, however, as described above

tr. ■

was, when winding up the film after shooting of the last image takes place, the counter reading of the counter C02 via the signal of the photographable number of individual images (0UT3) out / increases, and the output signal (0UT3) of the digital comparator CP3, which the signal of the number of images to be recorded (0UT2), which is stored in the data register RG1, with the count of the counter C02 compares, assumes Η level, and the output signal the NOR gate N0R1 assumes the L level; the transistor 0.6 is turned on so that the warning circuit 1002 is operated will indicate that no further photography

can be done while at the same time the transistor Q8 is turned off and therefore even when the trigger switch SW6 is closed, no tripping takes place. After the last picture is exposed on the film has been, the motor M is stopped in a state in which the winding of the film is completed.

Next, when the rewind lever (82 in Figure 2) is moved to the rewind position, the rewind switch becomes SW7 closed, and the counter C02 changes to subtraction mode, the digital comparator CP3 outputs a signal with the L level to OUT3 until the count of the counter C02 has been subtracted to such an extent that it is below a predetermined value which corresponds to that described above Way is determined. As a result, the output signal increases of the NOR gate N0R1 Η level, and the warning circuit 1002 stops working. Since the MOS transistor Q10 is in the OFF state, the transistor Q11 is turned on, and also the transistors Q14, Q18, Ö17 and Q12 are turned on so that the motor M is in the reverse direction rotates to rewind the movie. When the rewind switch SW7 is in the ON state, is transistor Q7 on and transistor Q8 off, and therefore triggering is prevented '. In addition, when the transistor Q11 is on, namely in the rewind state, the transistor Q3 is turned on through the reverse current blocking diode D4 to supply power to the

Bdehreltet and the count of the counter C02 is subtracted up to a certain value, the output signal of the digital comparator CP3 assumes the H level, and the MOS transistor Q10 driven by this output signal is turned on while the transistor Q11 is turned off, thereby stopping the reverse rotation of the motor M. In addition, the output of the NOR gate NOR1 becomes L level, "" and ". _f . Warning circuit is operated to indicate that the. Rewind is complete. The warning display is maintained until the rewind switch SW7. is opened even if the rear door of the camera is opened to open the rear cover open / close switch SW4. After the rewind is complete, the film magazine can be removed from the camera, with the front section of the film looking out of the magazine because the motor is not rotating, "even if the rear door of the camera is opened after the rewind lever is returned to its initial position , or even if the rewind lever has returned to its initial position after the

The camera cover has been opened. This is an advantage when using an automatic developing machine when developing films is used. If the first voltage source E1 is changed in the course of the photographing, arrives Voltage to the digital circuit 1001 from the second Voltage source E2, and therefore those in the data register RG1 stored film information and the counts of counters COt, C02 and C03 are all retained. When a CMOS logic circuit is used for the digital circuit 1001, that of the digital circuit 1001 consumed electricity will be lowered below the self-consumption of the battery, and its stand-by electricity consumption can be assumed to be essentially zero.

The method of multiple exposure will now be described. When an adjusting button 109 "'■■■ is pushed up according to FIG to interrupt the operative connection between the toothed wheel 6 and the toothed drum pinion 104. Now the end 122 'of the holding lever 122, which until then has been in contact with the flange 103, comes under the flange 103'.

Next, after the first image has been taken, a winding process is carried out, and since the Toothed drum 11 and the sink are not rotated at the time, only the shutter and mirror become tense. During the winding process, the holding lever 122 is due to the friction between the flange 103 ' the coupling 103 and the end portion 122 'of the holding lever pushed outward in the direction of the circumference, and the hold is released} but there is only one groove 103 'in the Coupling 103 is provided, the retaining lever slides on the pin part 104 'in the upper part of the toothed drum gear 104 and just makes one full turn, engaging groove 103 "and pin 104 ' come. If this is followed by a second exposure, a winding process then takes place, and the film is now being transported.

The following describes how to stop at the end of the film. The embodiment described above is designed so that the number of frames to be exposed on the film is stored in advance in the circuit is, the number of pulses generated by the toothed drum generator 25 is used to set a predetermined Transport number of individual images, and after the last individual image is exposed ^ a winding process takes place. At that time the circuit changes and it does

no voltage reaches the coil 27, namely itself then not when the trigger switch SW6 is closed, thereby completing the photographing process. However, this can also terminate the photographing process done that the opening of the take-up start switch SW2 after the completion of the first winding process after the sensor 24 has closed the film end signal opening (see Fig. 1) has detected, determined in order to then make triggering impossible. .

If the film, as shown in Figure 1, has the signal H between the perforations P and the film edge, the signal detectors 23 and 24 will be placed between an inner film guide rail 151 and an outer guide rail 152, as shown in Figures 5A and 5B is shown. Therefore, if the above-mentioned method of stopping the film is used, namely the method in which the detection of the film rear end is carried out through the end signal opening h _e on the film F and then triggering is prevented or * the film advance is automatically stopped, can, if the limit of the remaining film length is taken into account, the detectors between the inner guide rail and the outer guide rail and between the exposure port 153 and the film magazine chamber 154 _{quickly detect the signal hole h Q} coming from the magazine, so that in this detection process a relatively long one

Piece of film in the magazine remains in order for the next one Winding process to be available. This is effective when the delay in the stopping process of the film transport mechanism is taken into account, or if, as in the present embodiment, the last frame Ff is automatically wound around a piece even after the last exposure ", which one corresponds to another single image.

In the following another embodiment of the Toothed drum generator 25 and the sensor 26 explained.

FIG. 6 shows an embodiment in which light emitted by a light source 327 passes through the surface a generator 325 is reflected and received by a sensor, whereby the rotation is photoelectrically detected will. Figure 7 shows an arrangement in which a perforation detector light source 427 and a sensor are provided separately from the light source 23 and the sensor 24 for signal openings, so that the number of Perforations are counted photoelectrically when the perforations are moving.

Figure 8 shows a second embodiment of the present invention. In the following, only the differences with respect to the exemplary embodiment according to FIG. 2 are to be described .

First, how to load a film will be described. As in the previous embodiment, the pulse counter in the circuit is determined by the output signal of the Sensor started when the signal H arrives on the film at the point of the sensor 24 during film transport. An impulse is generated by the generator 25 rotated with the toothed drum 11 and the sensor 26, and after the aforementioned Counter counts a predetermined number of pulses corresponding to the frame before the first frame as if it were the zeroth frame or the zeroth single image, the coil 27 is supplied with current fed to weaken the attraction of the permanent magnet 28. Therefore, the armature tightened up to then becomes 29 released and the release lever 111 rotates to the right. Now the pin 111 'on the lever 111 comes into contact with a End 32 'of the holding lever 32 and causes the lever 32 to move counter to the force of the spring 33 to the right. Therefore the phase clutch 8 lowers and the pin 8 ' comes down into a groove on the phase clutch disc 7 »Since the winding-up limiting disc'60 and the limit lever 59 are engaged with each other, the clutch 8 cannot rotate. Consequently, the clutch disc 7 stopped, and also the gear drum 11 and spool connected to the clutch disc 7 are turned off 10 stopped. After that, the engine M starts idling through the slip mechanism 2. In this way the film F becomes a certain piece from the first signal

of the signals H transported and stopped at a certain point, namely a single image or frame in front of the image recording plane of the first single image with the number of frames preprinted on the film. On the other hand, when the holding lever is turned to the right, it rotates 32 der.Rückhaltehaken 35 to the left, and the lever 15 is pivoted to the left, so that the transport wheel 39 comes into engagement with the pawl plate 40 via the transport shaft 38 and thereby the preparation to advance the film counter 41 completes. To this At this point in time, the film counter 41 displays a "D".

Another end 111 "of the trip lever 111 moves to the right in FIG. 8 when the lever 111 rotates to the right. This places the pin 51 'at one end of the mirror hook 51 is moved to the right according to Figure 8, and the mirror hook 51 is pivoted to the left to enable the movement of the lever 52 in the direction of the arrow. The mirror is operated by a mechanism not shown pivoted up, then the shutter is operated, but before the circuit the amount of film advance detected by the pulse count of the pulses coming from the toothed drum generator, the shutter timing is detected is set to zero milliseconds in the shutter control circuit and the shutter curtain moves without being opened so that the film is not exposed.

When the shutter is operated, the mirror return signal lever 102 pivots to the right about the shaft 105 so that the limit lever 59 pivots to the left due to the mirror clamping lever 55 and causes the limit lever to disengage from the groove 60 ^! to come in the limiting disk 60. In this way, the upper sprocket shaft 72 becomes rotatable. In addition, the return of the mirror returns the lever 52 to its illustrated position. By making the upper sprocket shaft 72 rotatable, the motor which has been idling up to then due to the slip mechanism 2 causes the first gear 5 and the second gear to rotate, so that in the manner described in the first embodiment above, the sprocket 11 and the The spool 10 begins to rotate and the film is thus transported. The slip mechanism 2 works only during the film loading or insertion, and furthermore only for a short time, so that the life of the parts concerned does not suffer particularly.

The rotation of the gear 6 rotates the trip lever 111 via the phase clutch 8, the gear 61 and the shaft on the one hand and via the control cam 64, the roller 69, the lever 70 and the spring 71 on the other hand to the left, so that the armature 29 is attracted by the permanent magnet 28 will. Then, when the roller 69 comes to the portion of the control cam 64 having a small diameter,

the lever 70 is pivoted to the right by the force of the spring 73 and returns to the position shown. The rotation of the shaft 63 tensions the shutter mechanism and the mirror mechanism via the shutter mirror clamping cam 65 and the roller 67 on the one hand and via the arm 75, the pin 76 and the rod 77 on the other hand. The tension lever 33 returns to its illustrated position under tension of the driving force of the mirror mechanism, and the rod 77 returns to the illustrated position as the winding progresses. The film counter is advanced in the same manner as described above for the first embodiment.

In the following, the operation during a recording will be explained. This operation corresponds to the operation in the first Embodiment, but after the piece of the transported film corresponding to the first frame by the Circuit has been detected, the shutter control is performed with a predetermined shutter speed. Since the release pawl 50 In the first exemplary embodiment, however, the mirror is not triggered by the mirror retaining hook 51 is moved directly by means of the release lever 111.

The winding of the film and the stopping of the film occur in this embodiment as well as in the first embodiment, so that no further explanations are necessary.

As far as rewinding is concerned, the rewinding process is stopped as in the first embodiment, however, with the exception that the motor M is stopped immediately after the reverse rotation the toothed drum 11 generated pulses were counted up to a number that is necessary, thus the amount of film corresponding to the number of individual images to be exposed, which is stored in the circuit is wound up in the film magazine.

The second embodiment described above is intended will now be compared with the first embodiment. In the first embodiment, during preparation for photography the film is idle transported to the first frame on the film, and when a predetermined number of pulses corresponding to the first frame have been counted, power is applied the coil 27 in order to thereby loosen the armature 29 and to allow the phase coupling 8 to engage. The film advance mechanism is at the first frame of the film by the engagement between the take-up limit plate 60 and limit lever 59 are retained, and the release lever 31 is switched over by the change lever 49 into a mirror release state; furthermore, the motor M is rotated in the reverse direction to release the release lever 31 in FIG to reset its attracted position to allow for

to get ready to start recording. Also, while finishing rewinding, is in preparation for the next following insertion of a film and the empty transport, a detection of the phase of the solenoid reset cam 98 by the reverse rotation stop switch SW5 acts to stop the motor M in a position from which the release lever 31 can be actuated. In contrast, in the second embodiment, the film is shot up during preparation for photography transported idle to the zeroth frame of the film, whereupon the spool 27 for loosening the armature 29 Current is supplied to engage the phase clutch 8, thereby stopping the film and releasing the mirror , whereby the shutter is moved without forming an exposure slit, for one blank photographing cycle to obtain. Then the winding takes place to reset the armature 29, so that the readiness for the recording of the first single image is achieved.

Thus, the first embodiment of the invention can be effectively applied to a camera having a shutter with a mechanical limiter, namely with a safety device that prevents the The shutter speed becomes shorter than a predetermined shutter speed. This has the advantage that if the release button is pressed once while loading the film, preparation for taking the first

Individual image can then be done without superfluous Working noises are caused by the closure.

On the other hand, significantly fewer switches and switching levers are used in the second embodiment, and this design enables the transport up to the first single image through a simpler construction.

Furthermore, according to FIG. 2, the coil 27 is supplied with current, so that the film is stopped when the image recording plane of the first frame or, as shown in FIG. 8, the zeroth Frame has reached the position of the sensor, but taking into account the operational delay of each component, the coil 27 can also match such the count corresponding time current are supplied to the lies somewhat earlier than the pulses coming from the sensor 26 reach a predetermined value. In order to ensure in this case that the film at the zeroth frame or at first frame is stopped so that the pin 8 'does not get into a groove before or after the target groove 7' for the purpose of reliable engagement of the phase clutch 8, an adjustment of the forces of the springs 34, 30, 33 etc. would be effective, so that a timing control takes place according to which the pin 8 'passes down into the section between the target groove and the groove just in front of it.

After the sensor 24 has further detected the first signal opening Hq ₀ , the subsequent information signal H is read, the times of the pulses generated by the generator 25 and the sensor 26 and the pulses generated by the light source 23 and the sensor 24 possibly coincide, and they may not coincide if each time a pulse is generated by the sensor 26, the presence of the output of the sensor 24 is checked and stored in the circuit. In the two embodiments described above, the release magnet MgI works during the empty transport location of the film as part of a device for stopping the film transport mechanism to ensure that the first frame (in the first embodiment) or the zeroth frame (in the second embodiment) of the film exposure aperture opposite; Specifically, the magnet serves as a drive device for moving the phase clutch 8 and works in the subsequent photograph as the usual magnet for the release of the shutter. However, if the space and cost allows, discrete magnets can be used for these functions. Furthermore, the mirror lift-up lever 52 is shown as being retained by the mirror release hook 51, but the camera to which the present invention is applied is not a single-lens reflex camera,

thus the shutter can be suddenly started by the lever 52, and then the mirror return signal lever 55 provides a signal to the rear curtain and serves as a lever for detecting the movement of the rear curtain, for example, to detect the completion of the movement of the rear curtain . Even if the camera to which the present invention is applied is a single lens reflex camera, the shutter control mechanism can first be started by the movement of the lever 52, and then the lever can be swung up. Again in this case the signal lever ^ can be the signal for the rear shutter curtain.

According to FIG. 2, the main switch SW1 functions when it is inserted of the film as a start switch for the empty transport of the film (as a start switch for the motor M), and the main switch works while the first frame is being taken and then only as the main power supply switch, and changing the switch takes place in the Switching through the pulse counting of the toothed drum generator when a number corresponding to the first frame is reached while this can also be achieved by using the switch SWS already described.

Furthermore, in FIG. 8, for example, a film counter operationally assigned ßchaH-er SW9 must be provided, and while this is in the OFF state, the switch can

SW1 the function of the start switch for the motor M take over, and the shutter speed of the shutter control circuit can be set to a shutter speed in which the slot of the shutter is not opened (e.g. zero milliseconds), and during ON state of switch SW9 can switch SW1 to a mere main switch, and the circuit can be constructed so that the shutter control circuit works at the desired shutter speed.

The following is intended to provide further details regarding the addressed two embodiments described above will.

In Figures 2 and 8, the light source 23 is on the the side facing the camera cover, and the sensor is on the lens side, but of course you can these elements are arranged in reverse. The light source can be an incandescent lamp, a light emitting diode or the like. The sensor 24 can be a photodiode, a phototransistor, a photocell or the like. The release magnet Mg1 for moving the phase clutch 8 with such a timing that the clutch 8 in the engaged state is brought, can be replaced by a conventional electromagnet that, when he

is fed with electricity, attracts, and the im not er. excited state the armature 29 releases.

Figures 9 and 10 show examples of the circuit corresponding to the embodiment of Figure 8. In Figures 9 and 10 'are those components that have a similar mode of operation as the corresponding components in Figures 3 and 4, corresponding reference numerals and names given. How these circuits work shall be described below. As already explained above, the motor M rotates when the film is inserted into the camera and the cover of the camera is closed to close the main switch SW1 wind up the film, and the film information will be in the RGI data register stored. At this point in time, the output of the AND gate AND4 is at Η level, and therefore, the output of the NOR gate NOR2 goes to the L level, and the warning circuit 1002 operates. The output signal of the initial trip counter C04 becomes L when the counter is reset and when the counter is has counted a predetermined value, it outputs a signal with Η level. If the counter C04 emits the Η signal, gives the AND gate AND8 for a certain time, which is determined by R13 and C13 by the resistor R13, the capacitor C13 and the inverter INV4 from a Η signal, whereby the MOS transistor 021 is turned on and the

Trigger magnet Mg is actuated. The initial trip counter C04 is designed so that its output signal changes to Η level when he has counted the number of perforations that the time after The opening of the AND gate AND1 corresponds to, namely the time that has elapsed after the first opening Iiqq of the film information signal has been detected until a point in time has elapsed in which the image plane that was just before the first The single image to be exposed is located with the opening the camera is aligned, and this state does not change afterwards, even if pulses are input will.

When the output signal of the counter C04 assumes Η level, a trigger pulse is issued to turn on transistor Q21 and the camera is activated by initiating the Exposure control sequence triggered, but at this time the output of counter C03 is high, and therefore the AND gate AND4 also emits an output signal with Η level, and the transistor Q22 is switched on, so that without transistor Q9 on, the rear curtain is not held but is moved with the front curtain so that no exposure the film level takes place. Therefore, the mirror goes down immediately and the winding start switch SW2 is closed. When the first frame F1 coincides with the camera opening, the switch SW2 is opened, while at the same time the output signal of the counter C03 assumes the L level and the transistors Q5 and Q22 to

keep the motor M turned off so that the Readiness for normal recording is achieved. ■ In this case, the counter does not need to be reversed always take place synchronously with the opening of switch SW2, but the counter C03 can be inverted during the time between the closing of the switch SW2 after inversion of counter C04 and the renewed Open the switch SW2 by turning the Motor M is located. .

In the above description, the film information signal has been given in the form of openings or a combination of Openings and non-openings are shown, but this signal can also be of a different type.

Figure 11 shows a third embodiment of the invention, and specifically another embodiment of the engagement ^{mechanism 1 of} the phase clutch.

The operation of this arrangement will now be described. In this exemplary embodiment, too, takes place during When the film is loaded, the film is idly fed, but the motor M is rotated in the reverse direction during idle feeding. Then the gear 90 is through the One-way clutches 88 and 89 'rotated in the direction of the arrow. Then one is attached to the gear 90

Crankshaft 152 is rotated, and the end 155 'of a crank lever 155 is moved substantially to the left and right (as shown in FIG. 11) by the crank 153, a crank pin 154 and the crank pawl 155. Therefore, at a full. Rotation of the crankshaft 152, a feed ratchet wheel 157 is rotated further by one tooth. The number of teeth and the pitch of the feed ratchet correspond to the number of teeth of the toothed drum 11 and the grooves 7 'of the phase clutch disc 7, and therefore the teeth of the toothed drum are fed intermittently one by one by the reverse rotation of the motor M. If the transport pawl 155 is moved fully to the right according to FIG. 11, a so-called right center of death results, and the feed ratchet wheel 157 almost stops. By designing the grooves 7 'such that the then present position of a groove 7 ^{1 is} exactly below the pin 8' of the phase clutch 8, as shown in FIG. 12, and by suitably setting the timing according to that of the coil 27 is supplied with current by the signals coming from the generator 25 and the sensor 26, the pin 8 * can get smoothly into the groove 7 ¹ .

As shown in FIG. 13, the grooves 7 ^{1 can} alternatively be designed in such a way that the pin 8 'comes to lie just above a groove 7' when a stop pawl 158 stops the VorsGhüb ratchet wheel 157. In this

- 65 - ' ' ■ '- · ■ - ■ "■

In this case, a time zone is created within which the feed ratchet wheel 157 is completely stationary, while the transport pawl 155 begins to retreat to the left in FIG. 13 and begins to transport the next pawl 157 over the left center of death. If the coil 27 is supplied with current in synchronism with this time zone, the pin 8 ^{f will} smoothly engage with the groove 7 'in this case too. Specifically, in Fig. 12, the phase clutch 8 is reliably engaged regardless of the irregularity of the angle of reverse rotation of the toothed drum caused by the winding force of the film.

During the winding process, after each release the closure takes place after the idle feed has ended the motor M is rotated in the normal direction (this direction is indicated by a dashed arrow indicated). During rewinding, the motor M is rotated again in the reverse direction, and in this If the rewind button 167 is pushed up, before rewinding, the lever 165 is pushed to the right pivoted, and the plug rod 163 is moved against the force of a spring 164 upwards. By turning to the right of the lever 160 displaces a pin fastened thereon 161 the transport pawl 155, so that the end 155 * the Transport pawl 155 from the feed ratchet wheel 157

is withdrawn. In this way, the gear 90 becomes rotatable.

As in the first embodiment, then a rewind clutch, not shown, by the reverse rotation of the motor M via the gears 89, 90 and 91 driven to rewind the film.

According to the above description, the Fhasenkupplüng 8 is operated in this embodiment while it is in. stationary or almost stationary state, so that too far running between the grooves 7 ¹ and the pin 8 can be prevented. In addition, during the photographing, the winding is not intermittent but continuous, and this leads to a high winding efficiency and faster winding, with no undesirable noise being generated.

In the first two embodiments, the detected Filminformatipn and the amount of film transported are stored in the circuit, and this circuit is designed so that with regard to the time when the power source circuit was opened or the battery is used up and has only a small capacity, or when the power source is removed from the camera, a second voltage source is provided separately in order to prevent the contents of the memory circuit from being lost

goes. As a result, the first voltage source can be exchanged while the same film is being exposed. In this regard, the in Fig. 14 Second voltage source shown with safety device ensures absolute protection. Here is a safety hook 204 is provided on the flange 203 'of the lid 203 of the battery case of the second Voltage source E2 intervenes, and the arrangement is designed so that when the cassette 204 of the first Voltage source E1 is pressed into a position in which electrical conduction is ensured, the safety hook 204 by means of a locking lever 206 comes loose, and only in such a case can the second voltage source E2 be exchanged. In this way the camera can be prevented from being without a voltage source at any point in time.

If the memory contents of the circuit of the camera on this Is secured in a simple manner, an alarm sound or a warning lamp can be generated when the end of the film is reached can be turned on and the information obtained from the film can be in or outside the viewfinder the camera. For example, the film length of the film used or the film speed be brought to the display.

In contrast to the electrical storage of the recorded information explained above, is moreover the mechanical memory *, which will be presented in the following, is an effective tool.

The following describes an embodiment of the mechanical memory that is contained within the camera is arranged.

According to FIG. 15, the film F has the above-mentioned information opening h _{Q assigned to the perforations P.} The transport direction of the film F is indicated by an arrow. A light emitting element 523 or a light receiving element 524 is arranged on opposite sides of the information opening hg in order to photoelectrically detect _{the presence of the opening h Q.} A light emitting element 527 or a light receiving element 526 is arranged on opposite sides of the perforations P in order to detect the presence of the perforations P photoelectrically.

An information reading circuit 503 extracts information from the relationship between the photoelectric output of the light receiving element generated when the film F is transported, and the photoelectric Output of the light receiving element 524.

The circuit 503 provides film speed information in the form of an electrical signal to a pulse generator 504th

After receiving this information, the circuit 504 delivers to an electromagnet Mg3 a number of pulses corresponding to the film speed. A transport pawl lever 505, a stop pawl lever 506, a ratchet wheel 507, a resistance plate 508, which are coaxial and Is formed in one piece with the ratchet wheel 507, and a reset lever 509 together form the mechanical. Storage.

The electromagnet Mg3 pulls an armature 505a, which is attached to the Transport pawl lever 505 is provided against the force of a spring 505b each time it receives a pulse receives. By attraction, the lever 505 is pivoted to the left about a shaft 505c, and a transport pawl 5O5d at the end of the lever, the ratchet wheel 507 rotates one tooth width to the right against the force of a Spring 507a, which biases the ratchet wheel 507 to the left. The stop ratchet lever 5Ö6 prevents the ratchet wheel .507 is rotated to the left by the spring 507a when the attraction of the transport pawl is released by the electromagnet Mg3. In this way, the resistance disk 508 is in accordance with the from the pulse generator 504 generated number of pulses rotated. The domestic

ό '\ jjby ι

film sensitivity information obtained from the formation opening is stored mechanically as an angular rotation of the resistance disk 508.

An exposure circuit 510 receives the film speed information stored in the form of an angular rotation, which is in the form of a resistance between brushes 510a and 510b, which form a ground strip 508a or a resistive strip 508b on the resistive disk 508 * and the exposure circuit controls the exposure based on this Film speed. ".

When the camera lid is opened, the exposed To remove the film, a pawl 511 assigned to the cover releases the holding force of the reset lever 509. The lever 509 is pivoted to the right about a shaft 509b by a spring 509a, and the upright portion 509c of the lever releases the transport pawl 505 and the stop pawl 506 from the ratchet wheel 507. As a result, become the ratchet wheel 507 and drag washer 508 by the pretensioning force the spring 507a is rotated to the left and returned to its initial state. With the resistance disk 508 is connected via a rod 512a to a manual setting plate 512 which has the value indicated by the resistance value Information by means of a scale on the setting screen

indicates. If a film is used that does not have an information opening, the manual dial is used from Hand rotated to adjust the film speed. It is also possible to use the information provided by the Resistance value is indicated by means of an electrical display element via the circuit 510 for display bring to.

Figure 16 shows a modified embodiment. The detector arrangement includes circuit boards 623 and 624, which are arranged on opposite sides of the information opening hg in order to detect the presence of the information opening h _Q in an electrostatic-capacitive manner, and circuit boards 627 and 626 are provided on opposite sides of the perforations P to their Detect presence of electrostatic-capacitive.

The number of pulses output from the pulse generator 504 corresponding to the film speed becomes on given a pulse motor PM. The pulse motor PM rotates "according to the number of pulses supplied to it, and the rotation is transmitted to a toothed wheel 606 through a gear arrangement.

The gear 606 is activated by the pulse number input rotates the motor PM and rotates the ratchet 507 which meshes with it. A reset lever 609 releases the meshing engagement between the wheel 606 and the ratchet wheel 507 against the force of a leaf spring 613 by any Signal that occurs during the completion of the film exposure. The information reading circuit 503 provides the film speed information in the form of a digital one Signal also to volatile memory 605. Exposure circuit 510 normally receives the output signal of the memory 605, which has advantageous accuracy. The film speed information of the resistance value from the resistor disk 508 becomes used when the film speed information stored in the memory 605 has been lost for some reason, for example because the backup voltage source is used up.

FIG. 17 shows a further modified embodiment. The detector arrangement contains contact pieces 723, 724 and 726 and 727 for detecting the information opening 11q and ' of the perforations P by making contact. The resistance disk 508 has been replaced by a digital coding disk 708, and the film speed information becomes in the form of a digital signal is obtained by a plurality of brushes 710.

A reset lever 709 is used in place of the pawl 511 actuated by the impulse, which after the end of the photography all individual frames of the film accordingly the input of the information reading circuit 503 is generated will; the pulse arrives at a combination magnet Mg4, which has a similar structure to the magnet Mg1 according to FIG. 2. The magnet Mg4 attracts the lever 709 in the normal state by means of a permanent magnet and causes that the gear 606 and the ratchet wheel 507 mesh with each other. When the said pulse hits the magnet Mg4 is given, the lever 709 is released from the magnet and pivoted to the left by the force of the spring 709a, whereby the wheel 606 disengages from the ratchet wheel 507.

This pulse is generated when the detector arrangement 723, 724 has detected the information opening (h _Q in FIG. T) which represents the end of the film and which is provided in the vicinity of the end of the film F.

Fig. 18 shows an example of an arrangement by means of which the information contained in the information aperture of the film Detects information by some detector array, extracts the information and only the information regarding the number of film frames from the information

Reading circuit selected and not stored in the circuit, but directly mechanically in the film counter saved in the camera. In this way, from the extracting or reading circuit a single Bit or more information bits can be selected, and the information signal can be replaced directly are due to the extent of a mechanical displacement without storage in the circuit, so only a mechanical Storage takes place.

FIG. 18 corresponds to the state that it has been determined from the information aperture that the number of frames of the film is "36" and a mechanical down counter is set to "36".

When the lid is opened, one part of the ' Lid forming projection 850 moved in the direction of the arrow. After that, a sector lever 851 is turned clockwise rotated about a shaft 853 by the force of a spring 852. A gear 851a is provided on the sector lever 851, and by the rotation of this gear 851a is about a Gear assembly rotated a tensioning plate 858 counterclockwise. A roll pin is on the clamping plate 858 provided, the one surface 861a one at the lower end of the shaft 860, which is provided coaxially but separately from the clamping plate 858, located element 861

applied. As a result, shaft 860 becomes counterclockwise rotated against the force of a spring 862, and accordingly one becomes coaxial and integral therewith formed ratchet disc 863, a gear 864 and a film counter 865 rotated counterclockwise. Now will the scale provided on the film counter 865 to a position slightly behind the "36" with respect to an Iridex mark Turned 866. The scale on the film counter 865 is biased clockwise by a spring 862, and it tries to turn in the direction of "36" to "0".

If the lid is now closed with the film inserted, the projection 850 is moved in the opposite direction of the arrow to close the switch SW80 of the lid. Thereafter, a combination magnet Mg5 is energized, and a retainer lever 869 is counterclockwise by one Shaft 870 is rotated by the force of a spring 871 and enters the pawl portion 863a of the ratchet wheel 863. In addition, a conventional magnet Mg6 is excited, and.ein Lever 873 is rotated clockwise against the force of a spring 874 to a control cam 876, which is in one piece is formed with a shaft 875 to be released from the gear 864.

^ t> «W TW N. I '- b4.

When the lid is closed further, the sector lever 851 is urged by the projection 850 and rotated counterclockwise against the force of spring 852. By this rotation and by a gear arrangement the clamping plate 858 is rotated counterclockwise. Now the shaft 860 is activated by the action of the Retaining lever 869 is retained, and therefore the dowel pin 859 disengages from the surface 86la and reverses on its own back to its original position.

Then the information of the film counter is selected by the information reading circuit, and one for the information of the frame number on the film becomes a representative signal such as a period of time transferred to the magnet Mg5. The magnet Mg5 pulls the Retention lever 869 within a very short time by this signal is set, and allows the rotation of the pawl disc 863 due to the spring 862 im Clockwise. After the lapse of a predetermined time, the end 869a of the retaining lever 869 comes in Engage with the pawl portion 863b of the pawl disc 863 so that the rotation of the shaft 860 is stopped. Now the scale of the film counter shows 865 at "36". the Pawl sections 63c, 63d and 63e of the pawl plate correspond to the subdivisions "24", "20" and "12" of the scale, respectively.

When the film counter is set according to the number of frames, the magnet Mg6 in Dependency of the attraction release signal of the magnet Mg5 de-energized. Therefore, the lever 873 becomes counterclockwise rotated, and the control cam 876 comes into contact with the gear 864. In addition, dependent on the de-excitation of the magnet Mg6 is supplied with current to the coil of the magnet Mg5, thereby retaining the pawl plate by lever 869 to release. A gear 877 formed integrally with the shaft 875 is defined by the gear 878 rotated to transmit the rotation of the toothed drum, a similarity with respect to the gear 79 according to FIG Figure 2 is given. When the film has advanced by a distance corresponding to a frame, do so the shaft 875 and the control cam 876 one full revolution, so that the gearwheel 864 is transported by one piece, which corresponds to one tooth, and the film counter 865 is shifted by an amount corresponding to one division. In this way, the scale of the film counter is subtracted frame by frame to "0".

The arrangement according to FIG. 18 also has a manually operable frame number setting mechanism, by means of which it it is possible to set the number of frames manually if the film used does not have the corresponding information wearing. If the adjusting washer 882 against the forces of the

When springs 880 and 081 are depressed, it becomes a gear 883 placed in a position where it comes into engagement with the gear 864, and in dependence on this displacement the power supply for the magnet Mg5 is blocked, and the retention of the pawl disc 863 by the rear. holding lever 869 is canceled. Since the gears 883 and and 864 mesh with each other, the rotation of the dial 882 is transmitted to the film counter 865 via the gear 864. If the frame number scale to any desired If the number is set and the hand releases the disk 882, the disk 882 moves up into its original position. Then the magnet Mg6 is de-energized, the control cam 876 moves into a position in which it comes into engagement with the gearwheel 864, the engagement between the gearwheels 863 and 864 is released, the control cam 876 continues to mesh with gear 864, and film counter 865 rotates in a direction for subtracting as the film is transported.

FIG. 19 shows a further embodiment of the mechanical store. ■. ■

As in the embodiment described above, light emitting and light receiving elements are 904 and 905, respectively are provided to detect the film information signal H and are light emitting and light receiving elements 906 and 907 for determining the perforations P provided.

When the camera lid is opened, there will be a protrusion 911, which is part of the cover, is moved in the direction of the arrow, and a sector lever 910, which is similar to the corresponding lever from FIG. 18, is wrapped around a shaft 913 is rotated clockwise and a tensioning plate 919 is rotated counterclockwise via a gear arrangement. A projection 919a is provided on the clamping plate, and this projection 919a acts on one Surface 921a of an element 921 at the lower end of a shaft 920, which is coaxial but separate with respect to the clamping plate 919 is provided. Consequently, the shaft 920 becomes counter-ulcerated against the force of a spring 925 turned. As a result of this rotation, the spring 925 is tensioned with a biasing force which strives to be a one-piece to rotate the pawl plate formed with the shaft 920 clockwise. Now comes the end of 944a of the retaining lever 944 against the toothed portion of the pawl plate 922 to abut, whereby the pawl plate can only be rotated counterclockwise.

The pawl plate 922, a balance gear 926, a Resistance disk 927 and the graduated disk 928 are also formed in one piece with the shaft 920 and are turned counterclockwise when the lid is opened. The resistance disk 927 has a resistance and a ground track to provide the film sensitivity information. This arrangement is similar

of the resistance disk 508 according to FIG. 15, those mentioned Lanes are in contact with brushes 952 and 953, respectively. Brushes 952 and 953 are on brush plate 954 attached and are connected to the conductor tracks 955 and 956, respectively. Brushes 957 and 958 are in contact with the track 955 or 956 to find the "resistance value of the To transmit resistance to a circuit 2000.

The value of the resistance fluctuates with the rotation of the Resistance disks 927. Furthermore, the resistance value corresponds to the number of the index mark 954 on the Dials 928.

When the clockwise rotation of the sector gear 910, caused by opening the camera cover, is finished, the shaft 920 has been rotated counterclockwise so far that the end 944a of a retaining lever 944 comes to rest against the toothless smooth section 922a of the pawl disk 922.

The differential gear 926 forms together with the gears 929, 930, 931, the gear wheel 932 and the armature 933 one Regulation or compensation mechanism.

The reciprocating shaft 934 of the armature 933 is on attached to the lever 935, which tries to counterclockwise by means of the force of a spring 936 around a shaft 937

to turn. This rotation is restricted by a Pin 938 »and then the anchor 933 comes with the gear wheel 932 is engaged and fulfills a control function.

Responding to. the clockwise rotation of the sector lever 910 by opening the cover, the lever 940 rotates counterclockwise around the shaft 941 until it comes to rest against pin 943. now a pin 944 provided on the lever 940 rotates the lever 935 clockwise. Therefore, the armature 933 trips the gear wheel 932 and ends its control function. As a result, the rotation of the shaft 920 is stopped by opening the Lid independent of the control mechanism, and is not delayed.

This will complete the process of opening the lid of the Camera and tensioning of spring 935 completed. Now a film is inserted into the camera. If then When the lid is closed, the protrusion 911 causes the sector lever 910 to rotate counterclockwise.

This in turn rotates the clamping plate 919 clockwise. When the clamping plate 919 rotated a bit is, the toothed portion 922b of the pawl 922 comes into engagement with the end 944a of the retaining lever 944, and thereby the rotation of the shaft 920

313359Ί

restricted. The protrusion 919a, which continues to rotate in the clockwise direction, comes off the surface 921a of element 921. Now the control surface closes 927a of the resistance disk 927 den. Switch SW11. In addition, dial 928 points with respect to the index mark 949 the "Start" position. Towards the end of the im Counterclockwise rotation of the sector lever 911 by closing the cover causes the sector lever 910 the closing of the switch SW12. Furthermore, the sector lever 910 caused by the clockwise direction ensuing rotation of the lever 940 and counterclockwise the lever 935 is rotated so that the armature 933 approaches the gear wheel 932 to a position, in which the regular function is exercised.

After the rear door of the camera is completely is closed, the detection of the information signal by the blank advance of the film and the preparation for mechanical storage by the above described process completed. Figure 19 shows the state at this point in time.

When the information signal is detected, the electromagnet Mg7 by the signal from the circuit 2000. Electrically excited, and the retaining lever 944 rotates clockwise around shaft 951. Therefore, loosens

the engagement between the pawl washer 922 and the Retention lever 944, and the shaft 920 begins to rotate clockwise, taking advantage of the movement provided by the Tension spring 925 applied biasing force. The one above The regulating or compensating mechanism described causes the shaft 920 to move at a substantially constant lower Turning speed. With this rotation of the shaft, the resistance disk 927 is also rotated, and the change in resistance between brushes 957 and 958 is transmitted to circuit 2000. At a point in time when the film information previously acquired by the circuit x 2000 relating to the If the film speed and the information transmitted by the brushes 957 and 957 match, the power supply to the electromagnet Mg7 is cut off. Then turns the retaining lever 944 turns counterclockwise, and then end 944a prevents rotation of the pawl disc 922, namely the rotation of the shaft 920. Now the ASA scale of the dial 928 shows the ASA number of the inserted Films with respect to the index mark 945.

In the above manner, the film speed information was obtained mechanically stored.

A switch SW13 that is only active during the winding process is closed is provided in the winding lever portion. When the take-up lever 983 counterclockwise is rotated, a one-piece with a tooth

rad 967 formed shaft 988 counterclockwise rotated by a noiseless clutch, which consists of a clutch cam 984, control roller 985a, 985b, 985c and the gear 987. An annular spring 981 sits on the shaft 988. Corresponding to the counterclockwise rotation of the shaft 988 rotates the ring spring 981 due to the friction until the bent portion 981a of the ring spring comes to rest against a pin 989 and the spring 981 comes into contact comes with a wire 982; when the take-up lever returns to its initial position, the ring spring 981 disengages from the wire. The 981 spring and the wire together form the switch SWI3.

FIG. 20 shows the electrical circuit 2000 according to FIG. 19. In FIG. 20, a resistor 2119 is used for setting the film sensitivity is formed by the resistance disk 927 according to FIG. The output signal the photodiode. 905 is amplified and shaped by an amplifier circuit 2104 and becomes a flip-flop 2106 as well a data register 2110 transferred. The output signal the photodiode 907 is amplified and shaped by an amplifier circuit 2105 and transmitted to a gate 2107. The output of flip-flop 2106 is applied to the gate 2107 to control the opening and closing of this gate. The output of the gate 2107 arrives

to a counter 2108 and a gate 2109. The counter 2108 is used to count the number η between the perforations P according to Figure 1 and the perforation ρ + η and for recording the area occupied by the information signal H on the film. The output signal of the Counter 2108 is transmitted to control the opening and closing of gates 2109 and 2116. In the case of the data recorder 2110 is a memory circuit that the Output signals of the circuit 2104 are inputted, namely the information signal H and the output signal of gate 2109; the register stores the states of the openings hg and the non-openings hu of the information signal H by a "1" or "O" signal in successive Memory addresses which are identified each time a detection pulse is received from the Circuit 2105 comes through gate 2109.

In the data register 2110, there are various kinds of information relating to the film, which are specified by a combination of film information signals stored, e.g. B. the information regarding the film speed, the information regarding the type of film, the information about the number of frames to be recorded, the information concerning the density, etc. Of these different types of information, the digital signal, that reflects the film speed, to a D / A converter

setter 2114 issued. The D / A converter 2114 converts the digital signal of the film sensitivity into a Analog voltage and transmits it to the analog comparator 2115. The resistance value reading circuit 2118 converts the resistance value of the resistor 2119 into a voltage and outputs it to the analog comparator 2115. The analog comparator compares the output voltage of the D / A converter 2114 with the output voltage of the resistance value reading circuit 2118 and toggles a signal to gate 2116 which indicates the difference between the two Tensions based. A driver circuit 2117 controls the magnet Mg7 by the signal coming from the gate 2116. An exposure control circuit 2121 is set by the resistor 2119 in a known manner Film speed, the information provided by a photodiode 2120 provided in the measuring device of the camera controlled via the object brightness and other illumination setting factors. A power supply circuit 2113 controls the power supply through a voltage source, not shown, for the LED 904, 906, the circuit elements 2104-2112, the circuits 2114-2118 and the circuit 2122. A reset circuit 2111 generated simultaneously with the start of power supply by the power supply control circuit for a short time Time a reset pulse to reset the Flip-flops 2106, counter 2108 and data register 2110 to set. A warning circuit 2122 leaves one

Light-emitting diode 2123 flickers when the power supply circuit 2113 outputs power and generates it at the same time a piezoelectric tone generator 2124 a tone to thereby display and "warn that the following to be explained film information input is continued. The power supply circuit 2113 supplies to each Circuit current when both the switch 'S-Wl2 at Closing the lid of the camera is closed as also the switch SW13 is closed when the film is transported by the take-up lever and the ON signal of the switch SWIl from the delay circuit 2112 is transmitted delayed by a predetermined time; if one of the conditions is that there is a power supply, so this state remains independent of the position of the switch SW3, and after a certain time after opening the switch SW12 the power supply circuit 2113 independent of the switch SW3 switched off so that the power supply for each circuit is not affected. The condition continues of the power supply circuit 2113 to the exposure control circuit.

If the rear cover of the When the camera is closed, the switch SW12 is closed, and when the take-up lever is used to transport the

When the film is moved, the switch SW13 is closed. The switch SWI1 is also closed, since it is in was reset and held in the manner already described. As a result, the power supply circuit operates and this state is maintained.

The LEDs 904 and 906 are switched on, and each circuit part operates and when a perforation passes the detector section the circuit gives 2105 outputs an output to gate 2107 for each perforation; but there the movie information signal H does not exist in the predetermined area of the film corresponding to the perforations P ^ - P, that remains Flip-flop reset. The gate 2107 is closed by the output of the flip-flop 2106, and that The output of gate 2107 does not change. That The output of the counter 2108 is through the reset circuit 2111 is reset and gate 2109 is opened by the output of counter 2108; the Gate 2107 is closed, however, and therefore no pulse is passed from circuit 2105 to data register 2110, so that it does not save. Gate 2116, which works opposite of gate 2107, is closed, and the output of the analog comparator 2115 is not transmitted to circuit 2117, and no current flows to magnet Mg7.

Venn the first opening Iiqq of the film information signal H passes the detector section, the flip-flop 2106 is set, and therefore an output signal is inverted, to open gate 2107. Thereafter, every time a perforation passes the detector section, a pulse is output from the gate 2107 and counted by the counter 2108. Gate 2109 remains open, until the counter has reached a predetermined count, and the pulse for each perforation is in the Data register 2110 entered to successively shift the memory addresses of the data register, whereby the data register the presence of the film information opening, namely, the film information for each perforation simpuls stores. The warning circuit 2122 is operated by the power supply circuit 2113 so that the light emitting diode 2123 flickers and the piezoelectric Tone generator 2124 generates a tone to thereby issue the warning that the film information input continues takes place. This prevents the film transport for information acquisition during this Operation is interrupted. .

When the counter 2108 has counted η perforations, the counting is ended and the output of the counter is stopped is inverted; gate 2109 is closed and the film information is stored in the data register.

The film speed information in the data register is converted into one of the film speed information by the D / A converter 2114 corresponding voltage converted and given to the analog comparator 2115. In addition, the output of the resistance reading circuit 2118, when the resistor 2119 is reset to the starting position, in a relationship is selected, at which for each value of the film speed the analog comparator 2115 a signal with a Polarity for energizing the magnet Mg? and therefore the output of the analog comparator 2115 inputs Signal to excite magnet Mg7.

As described above, when the output signal is of the counter is inverted, gate 2116 is opened and the magnet energize signal energizes the magnet Mg7 through the magnet drive circuit 2117. As a result, the holding of the pawl 922 is shown in FIG Figure 19 is released by the retaining lever 944, and the shaft 920 is at a certain speed rotated by the driving force of the spring 925, and analogously with this, the resistance value of the resistor changes 2119} and also the output of the reading circuit 2118 changes. When the amplitude relationship between the output of the circuit 2118 and the output of the D / A converter 2114 is reversed, the output is

of the! Comparator 2115 a signal with a non-exciting Polarity decreases, so that the magnet Mg7 is de-energized and the retaining lever 944 returns to its initial position according to FIG. 19 in order to hold the pawl disk 922 in place. That is, it becomes a certain resistance value according to the film sensitivity information stored in data register 2110. In addition, when the resistor 2119 is changed, the switch SWIl is opened and this is transmitted to the power supply circuit 2113 by a predetermined time delayed by delay circuit 2112; these Time is necessary for the pawl disc 922 to rotate according to a maximum angle of rotation. Consequently Then, when the setting of the film speed in the resistor 2119 is completed, the hold becomes the power supply through the power supply circuit 2113 is reliably ensured. After a loading, At a certain time, the power supply circuit stops operating. Stopping the power supply prevents the warning operation of the warning circuit 2122, and thereafter the exposure control circuit operates in a known manner Manner based on the film speed information mechanically stored in the resistor 2119 is.

Figure 21 shows the power supply circuit 2113 and the delay circuit 2112 in detail.

In the power supply circuit 2113, which is connected in positive feedback, and a voltage source EB in common with the exposure control circuit 2121, transistors Q31, Q32 and resistors, such as it was described above, start when the switch SW11 is closed once while the switch is on SW12 is in the ON position, transistors Q31 and Q32 are in the feedforward mode, and thereafter the ON state of the transistor Q31 regardless of the Maintain the ON or OFF position of switch SW13. A circuit 3000 to be fed by the power supply circuit 2113 receives power from the Voltage source EB. Circuit 3000 includes the above mentioned light-emitting diodes 2100, 2102, as well as the circuits 2104-2111, 2114-2118 and 2122.

When the magnet Mg7 by the inversion of the output signal of the counter 2108 is energized, the switch SWi1 is opened, but the delay capacitor C31 of the delay circuit 2112 maintains the conductive state of the transistors Q31 and 0.32 for a certain period of time and thus ensures the continued Power supply. Then the OFF position of the Switch SV / 11 the reverse current through the diode D31 itself

then blocked when switch SW13 is closed becomes, and therefore the transistor Q31 is not turned on. .

As described above, the film speed information stored in the information signal provided on the film becomes film speed information automatically stored in the memory, which has a mechanical mechanism, and the information is held until the back cover of the camera is opened to remove the film will.

It can be seen that the film information signal is also different May include information, namely information regarding the type of film, the density, the number of pictures, the distinction between black / white and color, etc. Also this information is after a similar procedures are transferred to the mechanical memory. Furthermore, the device according to FIG. 19 equipped with an exposure correction mechanism. An exposure compensation button 959 is toward the Arrow movable and brought to a standstill by a snap device at certain intervals. One Rod 960 engaging a U-shaped groove 954a within brush plate 954 is on the underside of the Button 959 arranged. Thus, when the knob 959 is rotated, the brush plate 954 is rotated, and the brushes 952 and 953 are offset so that the

significant ASA film speed is changed and the exposure level varies. If the number of steps at this relative displacement and the The position of the exposure correction number on the button 959 with respect to the index mark 945 is prescribed Exposure correction possible.

If the lid of the camera is opened and closed once. is closed, button 959 is reset and retained by a snap device, not shown, in a position where it is with respect to the Index mark 954 indicates a "0". This reset is accomplished through the operation of levers 961, 962 and 963. This means that when the lid is opened, part 911 'of the lid moves in the direction of the arrow will. The lever 961 is then moved in the same direction, the lever 962, by the force of a spring 964 is rotated clockwise about shaft 967, and the lever 963 is rotated about the shaft 969 counterclockwise.

As a result, the up to then becomes exposure correction angularly displaced rod 960 returned to the initial position by one of levers 962 and 963. This exposure correction mechanism can be designed so that the Photographer does not move button 659 or immobilize the button by any means until

the ■ film information has been read and the brush plate 954 remains in its regular position during operation of the memory.
