Abstract

PURPOSE:To execute operations including releasing a shutter and taking up film by providing a program switch means setting the timing of when data imprinting signal is transmitted in the returning step of a shutter operating member. CONSTITUTION:The program switch means 60 is composed of a contact pattern obtained by patterning the trigger timing of a data imprinting means 6 and of a slider contact which slides and moves to the contact pattern in cooperation with a shutter diaphragm operating member. When said member moves toward a rest position from a charge position together with the start of a release action, an exposure control means 4 and a focal point control means 5 are triggered, and simultaneously the program shutter means 60 drives the data imprinting means 6. Consequently, data on data and time is imprinted onto film together with the exposure of an object, and is completely imprinted to instant that a shutter closing action is completed or right after that action. As a result, after a series of photographing actions is completed, the operation can smoothly shift to a film take-up action.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a camera having a function of imprinting a subject image and data such as date, time, etc. on a film during shadowing. For more details, see the data imprinting operation! 1411.3 Automatic focusing that can be performed in one step for the series of operations necessary for shadows, such as exposure, focusing, and shutter opening/closing.
The present invention relates to an automatic camera having an automatic film winding function.

[υ is American technology] There are many cameras that are easy to operate and handle, and are equipped with a data imprint mechanism that imprints data onto the film, along with a data image of the subject such as self-blade 1 focus date 2 hours or various 1 darkest data. Some proposals have also been made for a shutter drive mechanism and an automatic focusing mechanism, which are essential components of a camera. For example, JP-A-Sho fil-! by the present inventor. No. 10123 also proposes basic cross-passing for cameras.

On the other hand, there is also a technique to imprint various data, such as time, etc. on l1kE film. For example, U.S. Pat. etc.

In order to imprint data such as the date and time on the film loaded in the camera when taking a photo, it is necessary to imprint the data between the time the shutter is released and the completion of 1Mffl. be. However, simple r1
1. Even though it may seem like data imprinting, it is actually not easy +11. Generally, the average time required for data imprinting by a data imprinting mechanism composed of electroluminescent elements such as light emitting diodes is approximately 60 milliseconds. This data imprinting time is 1760 seconds and the shutter speed is approximately 1
7 milliseconds, which is longer than the J focus! It is much longer than the 111 distance required for tIR photography, the 111 distance required to drive the lens, and the time required for automatic exposure setting. In order to meet the need to reduce the size and weight of the power source and its electric circuit required for light emission in terms of the light emitting efficiency of the light emitting diode, this is currently required. iI1 production time (6[1mi1+8)) is almost the limit.

[Problem that the invention seeks to solve]

Therefore, photo 11°a 'J3 11. Automatic metering and exposure settings, auto ih +1lll distance,
Another problem for automatic cameras with a data imprinting function is how to incorporate the data imprinting operation into a series of lens, focus setting, and shutter opening/closing operations.

Up to now, 61 data imprints were performed, and 111 steps were performed prior to the series of shooting operations consisting of photometry, distance measurement, and shutter opening/closing.
A pre-method and a post-method were considered.

1] The applicant's 11th method is the above-mentioned U.S. Patent No. 4.
There is No. 327, 979.

This method is a preliminary operation (shirt release 1) η automatic focus before the focus adjustment that starts the series of shooting mentioned above. The data imprinting operation is being executed in the early part of the work. Therefore, the preliminary movement performed at °i (before the series of shadows #1) delays the shirt release time, and 11! There was a drawback that the time required for shadows was longer.

In addition, in order to time the shirt release with this -H11ii method, if you imprint data at the same time as pressing the release button or release lever, the data will already be imprinted even if a condition such as underexposure occurs. There are also inconveniences such as not being able to shoot in the Middle East because it is imprinted on the film.

On the other hand, the latter method, that is, exposure! In the method in which the data imprinting operation is executed by the operation of the shutter, which is closed after completing the IJ image, it is not possible to automatically wind the film immediately after the shutter is released, and the film winding and L unwinding cannot be performed during the data imprinting operation. If this happens, a so-called image drift phenomenon will occur in the imprint data.

In other words, ¥1τ11; 1 system is a series of 1i11133!
Prior to the II1 work, and after the 5th car method, we ensured a relatively long time for inserting the data as explained in Section 1.
1', making it unsuitable for quick photography or quick-shot photography.

For these reasons, there have been expectations for the development of a device 1ff that can effectively imprint data during a series of photographic operations such as photometry, distance measurement, and shutter opening/closing.

[Object of the Invention 1] An object of the present invention is to record date, time, and date data on the film in parallel without interfering with the series of operations of photometric exposure, distance measurement focusing, and shutter pause during shutter release. surely,
To provide an automatic camera that can perform effective imprinting, thereby quickly executing everything from shirt release to film winding, and that does not require the camera to become large and heavy due to the installation of a data imprinting mechanism. be.

Another object of the present invention is to be able to perform photometry and distance measurement operations before triggering the shutter release by pressing the release lever that releases the shutter, and in the case of insufficient exposure, etc., without imprinting data. To provide an automatic camera having a data imprinting function that enables a shirt release to be arbitrarily set during IL.

[Means for solving problems]

In order to achieve the above object, the automatic camera of the present invention has an automatic focusing point II that drives the camera lens by 1.15 points.
an exposure control means for determining an aperture suitable for photoelectricity of the till Fr-stage and a two-liquid photographic object; a shutter driving means for driving the shutter to open and close; and a shutter actuating member for returning to the rest position from the charged position at the time of release; : one stage program switch that sets the timing for sending out a data imprint signal in the backward fI+1 stroke of the shutter actuating member; and data imprinting means for imprinting desired data onto the film in response to the data imprinting signal from the program switch means. The program switch means is composed of a contact pattern patterning the trigger timing of the data imprinting means, and a slider contact that slides into contact with the contact pattern by working with shutter aperture #11 and #14. It consists of At the start of the release operation, the shutter aperture operating section (I is at the charging position; from rt to rest position 1)
When moving toward n, the exposure control means and the focus/relie control means are triggered and at the same time the program switch T-
The data imprinting means is driven by 1'A. As a result, data such as date and time are imprinted onto the film along with the exposure of the subject, and data imprinting is completed at the same time or immediately after the shutter closing operation is completed, and as soon as the series of photos 1 and 1 are completed. You can move to film winding operation.

Among the pushing strokes of the shirt release lever that trigger the 4 m return movement of the shutter diaphragm making member,
By activating the exposure control and 11 means in the middle standby period and setting the trigger point of the shutter aperture operating member in the latter half, it is possible to execute the primary light regardless of the shutter release, and the f1 function is activated only when the exposure is normal. You can take a photo of the star shadow. Therefore, problems such as insufficient exposure can be detected.

(White!? JI camera's U100) Prior to explaining the data imprinting operation, which is the characteristic function of the present invention, the basic operation of the automatic camera will be explained next by referring to FIGS. 2 to 7. do.

In the present invention, film winding is not directly related, so it is omitted from the camera configuration shown in the figure, and its explanation will also be omitted. Note that Figure 2 shows a disassembled state of the parts on the back side of the board fixed in the camera body. 3 shows a disassembled state of the surface side parts of the base 111i+A.

(Shutter shutter opening/closing operation) The main movement element in the camera drive mechanism is connected to the shirt shutter release (shutter button) 11 and the shutter 37.
A release lever 1 that triggers the movement of each moving member including
The shutter operating member 20 controls the opening and closing of the 0 and 2 shutters 37, and the aperture setting mechanism determines the shutter aperture (aperture).

The release lever IO, which moves downward when the shirt release 11 is pressed down, is supported so as to be slidable in the vertical direction by fixed bottles pl and p2, and is given an upward biasing force by a spring 12. .

The main switch I is located on one side (front side) of the release lever 10.
3 is provided. The main switch 13 consists of a sliding contact piece 14 fixed to the release lever 1O and a contact pattern 15 formed on a circuit board p3 fixed to the substrate A. As shown in FIG. 5, the contact pattern 15 consists of a ground contact 16a having a length approximately equal to the movement stroke ε of the release lever 10, and a power contact 15b set in the latter half of the surface profile β. . Stroke flood +)il
Contact 1 +5c is a dummy contact. That is, when the release lever 10 is pushed down, the sliding contact piece 14 contacts the power supply contact 15.
(The section ljD I + does not turn on. This section is the idle section.The release lever
When 10 is pushed up further, the sliding contact piece +4 becomes the power contact +5
When it comes into contact with b, the main switch turns on, and the entire camera turns on.

The trigger point is set slightly before the lower limit point of the stroke of the release lever 10. Contact piece! 4 is power contact +5b
One standby section S is from when the trigger point T comes into contact with the trigger point T.

The shutter actuating member 20 is supported by a fixing pin p3.94 so as to be movable laterally relative to the substrate. This shutter actuating member 20 is biased in one direction by a spring 21, and is normally at an initial position (rest position 1'eI).
The state shown in FIG. 4 (8)) is then set (the 1). Then, the film winding operation, which is executed by operating the film winding motor (not shown) or operating the film winding lever, is performed. The shutter actuating part 20 moves against the spring 21 to the other side (2nd left direction in FIG. 4(A)).
and reaches the charging position (the state shown in FIG. 6). Made by Shatta! A resting member 22 for keeping the No. 11 member 20 in the charging position in a standby state is axially loaded onto the board with a pin p5. This locking member 22 comes into contact with the eyebrow j7123 formed on the shutter actuating member 20 to prevent the return movement of the shutter actuating member 20! 1 +I: A stopper arm 24 that is attached to the release lever 10, a hook arm 25 that hooks one end to the other end of the spring 12 attached to the release lever 10, and a trigger when the release lever 10 reaches the trigger point T by downward movement of the release lever 10. It has an actuating arm 26 that abuts the piece 16. Therefore, when the shutter actuating member 20 moves to the charging position during film winding, as shown in FIG.
3, the member 20 is prevented from being pulled back by the spring 21, and the shutter actuating member 20 is charged 117.
Moor to ftff. In this state, release lever is 1O.
When the trigger piece 16 presses down and passes the trigger point T, the trigger piece 16 suppresses the hook arm 25 in the direction opposite to the biasing direction of the flap 12, and the stopper arm 24 is pressed against the shoulder 1lls 25 of the member 20.
to allow return movement of member 20.

A cam 11-material 27 is provided at the shutter f 11 (+420).A constant speed is provided via a graph gear 31 that is connected to this cam member 27 and converts the reciprocating motion of the member 20 into rotational movement. The movement of the member 20 (M~ is transmitted to the mechanism 32. As a result, the return operation of the shutter actuating member 20!
I is dumped appropriately.

-1- The shutter opening/closing mechanism controlled by the shutter actuating member 20 includes a shutter actuating member 33 that comes into contact with the rear end of the member 20, a tap member 34 that is pivotally attached to the member 33,
The member 33 is placed in the charging position. Lock: M (1 block from the material 35 and the shutter opening/closing member 36 which opens and closes the shutter blade 37 by being pressed by the tap member 34. The movement of each element of the shutter opening/closing mechanism is shown in FIG. 4 (8). This becomes clear by comparing the rest state and the charged state shown in Fig. 6. That is, when the shutter actuator 20 moves leftward from the rest state shown in Fig. 4), the shutter actuating member 33 rotates counterclockwise. At the same time, the tap 1llr 34 pivoted on the B71 material 33 comes into contact with the bottle 31ia provided at one end of the shirt opening/closing member 36. The shirt opening/closing member 36 is biased clockwise by the spring 38, and the guide pin 36a at the other end is guided to the slot h to the board, so that the tap;

pass through. At the same time, the locking member 35, which is biased counterclockwise by the spring 38, moves the shutter actuating member 3
3rd stage ijR: engages with 13a and enters the charging state shown in FIG.

When the release lever 10 is pushed down to the trigger point T in this charged state, the trigger piece of the release lever 10! 6 is in charge! Then, push down the actuating arm 26 of the member 22 to rotate the third arm 22 counterclockwise against the spring 12. As a result, as shown in FIG. 7, the distance between the shoulder part 23 of the shutter actuating member 20 and the part 22 is removed.・The collar arm 24 comes off. When the stopper arm 24 comes off, the shutter actuating member 20
is returned to the right in the figure by the spring force of the spring 21. As the shutter actuating member 20 returns #I, the member 20
The claw 28 locks: When 11 is pressed against one end of the material 35, 3
When turned once, the stepped portion 33a of the shutter activation member 33
The locking member 35 comes off. As a result, the shutter actuator t433 rotates in the clockwise direction, and the tap member 34 pivotally supported by the member 33 taps the action pin 36a of the member 36. The guide bin 3 [ib] moves in one direction to open the shutter blade 37. After this, the shutter starts +1 s.
The tap i of the material 33, the material 34, passes through the working bin 3rIQ of the shutter opening/closing part (a 36) and comes off below the working bin 36a.

As a result, the shutter opening/closing member 36 returns clockwise to close the shutter blade 37. Once the shutter blades open and close, it's all luck! The IJ element returns to the rest state shown in FIG. 4 (8), but at this time, the automatic winding function is activated and the film winds up and moves to the charge state shown in FIG. 6.

(Automatic aperture operation - exposure control means) Between shutters! j
The opening formed by the shutter blade 37 during the II operation is set in the following manner, and the exposure of the light m from the object passing therethrough is reduced by 1.

The light intensity of the subject is photoelectrically converted by the photoelectric conversion element 41, and the light m signal Se is sent to the aperture control circuit 4.
When given, the appropriate exposure (No. A St) programmed in the aperture control circuit 4 is created. (inversely proportional relationship) is supplied as an excitation current to the electromagnet 42, which is fixed at 2!?ffA.

Exposure that determines the size of the shutter opening 12
The aperture setting mechanism with 11 means includes an aperture control circuit 4, an electromagnet 4
2, a shutter actuating member 2 that can reciprocate laterally.
The spring 4 has a reverse Il claw 44 set at 0 and 1 and -11-.
The aperture setting member 43 is biased in the return movement direction by 5.
And, the l1tl of the electromagnet 42 + the suction attracted by the magnetism
It has a plate 47 that engages with the non-return claw 44 to stop the movement of the diaphragm setting member 43.
(The material 46 and the aperture setting 1 Hayabusa material 43 have an inclined S'1 edge 411.
It consists of an aperture regulating member 48 with a and a of 1.

At the time of the above-mentioned shirt release (FIG. 6), the shutter actuating part 20 in the charge position is triggered and moves to the rest position; at the same time, the aperture setting iM screen 43 is also moved towards the rest position by the handle 45. Movement - As mentioned above, a current is applied to the electromagnet 42 for a period of time determined by the amount of light of the subject starting from the trigger point, so the braking member 46 is set to the aperture setting as shown in FIG. Member 43
from! JaL is there. I determined by the light of the subject
)! After 3 seconds, the current supply to the electromagnet 42 is stopped, and the braking member 46 is moved toward the rest position 16 by the spring force of the spring 46a.
Reverse 11 of T-tei 443 - engages with pawl 44 and aperture setting member 4
As is clear from the above, the return movement of 3 is completed after a length of time determined by the light of the subject (Fig. 7). Since the IiI member 46 engages with the non-return pawl 44, the number of teeth of the non-return pawl 44 to be engaged is determined by the amount of light. This, as shown in FIG. 7, limits the upward movement of the guide bin 3fi of the shutter opening/closing part 36 that comes into contact with the inclined edge 48a of the aperture regulating member 48. That is, as described above, the shutter blade 37 is opened and closed by the counterclockwise movement of the shutter opening/closing member 36, but the guide bin 3 [i
Since the upward movement of lens b is regulated by the inclined edge 411a of the diaphragm regulating member 48, the aperture diameter of the shutter blade becomes a size corresponding to the subject light 1. Therefore, proper exposure can be obtained by controlling the exposure signal from the aperture control 211 circuit 4.

After the shutter is opened and closed, the shutter operating member 20
returns to the rest position; rt, but the aperture setting member 43 does not return to the rest position (FIG. 4(^)) and shifts to the charging state (FIG. 6) at the time of the next film winding.

(Auto-focus operation - by focus control means) The camera of this embodiment has a two-focal type auto-focus function that is commonly used in compact cameras, but the present invention is particularly limited to this type of auto-focus function. isn't it.

As shown in Figure 3.4 (b), focal point III is where the lens is moved back and forth for one shot! The Jj means is a lens drive device which is screwed onto the lens holder 53 fixed to the substrate and the lens 51 while holding the lens 51, and moves the lens 51 back and forth along the optical axis by rotation with respect to the holder 53. A lens drive #ltRhM consisting of a member 54 and a locking member 55 that stops the lens drive unit 54 at a constant angle.
The main (1 has as a child.

In this example, Lens Drive! Jl+'+T5 material 54 is such that when the shutter release is performed, the backward motion of the shutter actuating member 20 causes the claw 28 of the member 20 and the arm protruding from the member 54 to
4a and rotates. Lens drive member 54
Lens 5 by rotation! moves from the front to the rear, or vice versa. Therefore, depending on the distance to the subject, stop the lens drive #J member 54 immediately after starting rotation! ! Either the far distance one star shadow or the near distance one star shadow can be set by rotating the nl (1454) to the limit.The means to achieve this is by using the lens drive unit It is a stepped portion 54b formed on a part of the periphery of the lens drive!Start rotation of the i11 member 54!In the 1.7th period, activate the +li+I function 55.
By setting the second stage jFB 54 b to 1, the lens drive #I is set to 1111. On the other hand, if the projecting portion t455 is not operated, the lens driving portion 54 rotates to its limit. Therefore, depending on whether or not the member 55 is actuated in relation 1, it is possible to set whether the focus is near or far. 1E for this person
IlIi 55 is the stem 4 provided in the braking member 46 mentioned above.
As described in lj7, the braking member 46 needs to remain engaged with the non-return claw 44 of the aperture setting member 43 when the shirt taller is released. 43 is executed after the release trigger is performed until the shutter blade 37 is opened. In reality, as shown in the timing chart of FIG. 8, i+111 immediately after the release trigger T.
The distance fAF'l is executed, then the lens drive for focus setting [8Fl is carried out, and then the aperture setting (
Since AF and l are executed, the movements of the electromagnet 42 and the non-return claw 45 do not conflict and are restricted to the execution of two different functions.
+31 (these works including +446 j elements) (can be rivered).

(1 piece of data imprinting) Data imprinting on the film in the present invention is performed at the time of aperture setting) υl as shown in the timing chart of FIG.
By executing fAl, l and the shutter opening/closing timing (S+t+) in parallel, the time required for the darkest shadow in Photo 1 can be shortened.

As described above, when the program switch means 60 is turned on, data printing is performed from the imprinting circuit 6 by sending a predetermined data signal to the means 61 to print 011 on the film.
Data such as 1 hour is imprinted.

The start of the data imprinting Jh operation is determined at the same time as the lens driving operation fAFl for setting the focus, or immediately thereafter (in the case of FIG. 8). As shown in FIG. 9, the program switch means 60 for executing this includes a contact portion 62 having a slider contact 63 attached to the shutter actuating member 20 movably held relative to the substrate, and a base. ! &A
It consists of a contact pattern 64 formed on a temporary print 65 fixed to the contact point pattern 64.

The slider contact 63 here has a bifurcated shape! It has a configuration consisting of a pair of conductor pieces 63a and 63b, and correspondingly, the contact pattern 64 is connected to the input column +1i and the output column R.
The signal from the input column 11i is output to the output column rlo via the slider contact 63 at j:A. In addition, the contact pattern 64 is formed to be able to send out control outputs (C1 to C31) of at least three toys. That is, as shown in FIG. At the output point C2, 11 signals representing data imprinting timing are sent out, and at the output point C3, a signal IIW is sent out when the lid shadow is completed.

The pattern contacts between the power points C2 and C5 are ground contacts for ensuring stable operation of the electronic circuit, and are not directly related here, and the present invention does not define such patterns.

As can be seen from the timing chart in FIG. The operating time required for this can be reduced.

However, the shutter actuating member 20 is triggered to release the shutter, and the luck is restored! At tII, the data imprinting operation is started when the slider contact 53 moves from the output point C1 to the output point C2. After that, self
j The slider contact 6 indicates that the aperture operation and shutter opening/closing will be performed, and a series of shooting operations and data imprinting will be performed.
3 reaches the output point c3, and the 1st shadow operation is completed. In reality, since the slider contact 63 sends out the film winding signal RW at the output point C3, the film continuously shifts to the charging state for the next photographing operation.

In the above embodiment, since the bifurcated slider contact 63 is adopted, the contact pattern 64 is connected to the input column +1i and the output column +1i.
1o, but a single row contact pattern is also possible, as shown in FIG. 1O. That is, li! is applied to the shutter actuating member 20. 1! ! While providing a slider contact 63', a contact pattern 114' on the fixed side is also created! It is formed of a plurality of conductors at intervals corresponding to the 1j timing. In this case, an equivalent function can be obtained by applying a signal current directly to the shutter actuating member 20 or the slider contact 63', outputting a signal from each contact pattern conductor, and applying it to the jrll+ control circuit to discriminate the signal. can.

Alternatively, as shown in FIG. 11, a three-pronged slider contact 63
It is also possible to make the contact pattern conductor 64, which sends out the data imprinting timing signal, independent and create a 3-terminal configuration using ".This configuration may be necessary due to the design, and although it may complicate the sideways, , reliable operation can be expected.

Furthermore, in the illustrated embodiment, the slider contact 63 is moved;
Although the contact pattern 64 is fixed, the contact pattern may be formed on the Mt material 20 for movable shutter operation, and the slider contact may be provided on the substrate side.

FIG. 12 is a schematic configuration circuit diagram for explaining the operation of an electronic control section including an aperture control circuit 4, a focus control circuit 5, a switching section 7, a sensitivity setting circuit 8, and an underexposure warning circuit 9. The operation of the circuit and the data imprinting operation will be summarized according to this circuit diagram.

The automatic focus operation by the focus control circuit 5 is performed using the release lever.
When the main switch 13 is turned on by pressing 10, the infrared light emitting element LIED I emits infrared light toward the subject, the reflected infrared light from the subject is received by the light receiving element pn, and the two outputs of the light receiving element PO amplifier a1. a2 to the difference #lIJ amplifier a3 to extract the difference component between both outputs,
The comparator a4 compares the difference component from the differential amplifier a3 with a preset reference level to determine whether the distance to the subject is long or short. On the other hand! Switching the transistor Trl in the power state 0 For example, when the subject is close, the transistor Trl is turned off, the state is determined by the first latch circuit Ll for autofocus, and the transistor Tr2 and the transistor Tr3 are turned off. The L transistor Tr3 is made conductive. This conductive state is maintained by the first latch circuit L1 for a predetermined period of time, and the Tr1 magnet 112 is
B. The lens member 11: brings the member 55 into the non-engaging IL state to allow the lens to be rotated for the set time. With this, it is possible to give the lens a focal length corresponding to the above settings ++ and '1.

Aperture setting is executed as follows. The sensitivity identification means normally provided in the film cartridge stored in the camera is detected by the sensitivity setting port 1llll17. 16 is determined based on the sensitivity standard by detecting the target to n range, and the light m of the subject is measured by the photoelectric conversion element 41 of the underexposure warning circuit 9. Do.Light m
If there is a shortage, the warning elements 11-132 are driven to emit light to issue a two-tone alarm. Aperture system (sensitivity above with comparator a6 of wholesale circuit 4) On the other hand, the main switch 13 is turned on and the transistor Tr of the jIII+ 1211 circuit 4 is stopped by the second latch circuit L2 which performs a latch operation under the control of the oscillator OSC and the counter CC.
'+, Tr4. Switching Tr3 and electromagnet 4
2 is once excited and demagnetized after a certain period of time. Therefore, the aperture setting returns to -111 with the return of the shutter part J↑A 20. After returning the A 43 for a certain period of time, the control member 46 is properly stopped +L and engaged with the non-return pawl 44 of the member 43. This allows the aperture setting operation described above to be performed.

The data imprinting operation is performed while the first latch circuit L1 of the focus control circuit 5 is controlling the transistor Tr2.
When the program switch means 60 reaches the output point C2 in cooperation with the return movement of the shutter actuating member 20, a data imprinting command signal is outputted from the terminal V to the data imprinting circuit 6 (FIG. 1). As a result, data is imprinted onto the film at an early timing.

Above: 1III i1 The circuit of the people in section 22 is not limited to the configuration shown in the figure. Any circuit configuration may be used as long as it achieves the operation, and the present invention does not particularly limit the circuit configuration.

Furthermore, although the above embodiments have been disclosed as being applied to a compact camera as an example, the data imprinting 'Al! 2 can of course be applied to various automatic cameras such as single-lens reflex cameras.

〔Effect of the invention〕

As explained above, according to the present invention, data such as date and time can be effectively transferred to film without shortening the time required for one set of shadows including automatic exposure, automatic focus, and shutter opening/closing. Imprinting can be done reliably, and the process from shirt release to film winding can be carried out quickly. Moreover, since the program switch means that defines the timing of data imprinting is a simple l (l + 4) added to the shutter actuating member, it is suitable for reducing the size and weight of the camera. Since light metering and distance measurement are performed without imprinting data, it is possible to stop shooting after confirming the lack of light, etc., thereby avoiding inconveniences such as failure of the closest shadow. I can do it.
