Description

[Detailed description of the invention] In order to improve portability, it is related to a thin camera arranged in a thin VC configuration.The aim is to create a camera with good portability, operability, and performance. Automatic exposure control (A,
B) Cameras, which had not been previously incorporated, have become electronic, and have progressed to the point where actuators such as magnet motors are used for exposure control and film feeding, and these sequences are electronically controlled by microcomputers.

In addition, electronic display of date and time using a liquid crystal display (LCD), etc., and data recording, which is the recording of the date and time on film, are also being carried out.

As mentioned above, although the number of cameras has progressed significantly, the final outputs, such as the shutter blade operation t1 of the electronic shutter and the winding mechanism for film feeding, still achieve their purpose using mechanical parts. O Conventional cameras are generally equipped with electronic cameras.This has the advantage of being a unit with each function completed, and is compact and compact for portability. However, if the sequence control of the entire camera operation is to be centrally controlled using a single chip IC, the wiring route to the valley unit will be long.In a narrow space, signal lines through which weak currents flow, motors, magnets, etc. When a long drive line is installed, which carries a large current, it throws away noise along the route of the wiring, which often causes malfunctions and malfunctions.In particular, signal lines often pick up noise, so Some means to remove the noise is required.

In response to the demand for better portability as conventional cameras have become smaller, the present invention has been developed to provide good portability by making it thin enough to fit into a pocket, for example, and to reduce the wiring route of the signal line. This was done for the purpose of shortening the time as much as possible and eliminating malfunctions due to noise, etc., and the above purpose was to shorten the exposure system unit as much as possible and eliminate malfunctions due to noise etc. This is achieved by a thin camera in which a drive system unit including at least an exposure drive section and a film feeding section is arranged in a plane.

That is, the present invention provides a more advanced electronic camera.
This is a new control system unit that includes the 1tIJ control circuit, and has been made thinner by arranging each unit on a plane, eliminating the need for signal wiring between each unit. This is a completely new arrangement compared to the conventional camera configuration.

The present invention will be explained in detail below using the drawings.

FIG. 1 is a schematic layout diagram of a camera seen from the front, showing an embodiment of the present invention. In the figure, a film is stored in a cartridge 1, and the film in an upper film chamber 11 passes through an aperture 12 provided in the middle of the cartridge 1 and is wound into a lower film chamber 13. Aperture 1
2 has a retractable lens barrel 2 that incorporates an f-image type lens, a shutter blade, and an aperture 12.
At the edge of the screen, there is a data recording mechanism 3 for imprinting the date, time, etc. on the edge of the screen.

This cartridge 1, the lens barrel 2 provided in front of the aperture 12, and the data recording mechanism 3 together constitute the exposure system unit 100. In this embodiment, the data recording mechanism 3 is also included in the exposure system unit 100. Although it is intended to be included, it does not necessarily have to be enriched.

On the left side when viewed from the front of the camera are an exposure drive section 4 that drives the opening and closing of the shutter, and a film #1f feed section 5 that feeds the film in the cartridge I, both of which are driven by a single motor M. 1. The lens drive unit 6 that protrudes the collapsible lens barrel 2 to the photographing position is also driven by the same motor M4C, and the drive system unit 200 is driven by the OMM drive unit 4 film feeding unit 5 and lens drive unit 6. Also, on the right side when viewed from the front of the camera are the IC for controlling the drive of the camera in general and the battery B for power supply.

There is a capacitor C for the strobe, and on the front there is a light receiving element PC, a strobe light emitting part IP, and a liquid crystal display part LCD.

Light emitting diode display LID and button P
There is a finder 400 in one corner of the zero control system unit 300 constituting the control system unit 300, and a release button 500 is provided on the top surface of the camera.

Exposure system unit 100 located in the center when viewed from the front of the camera
The data recording mechanism 3 is provided on the side close to the control system unit 300, and the signal line to the data recording liquid crystal provided inside the camera for data recording is configured to be extremely short. The general arrangement of the thin camera according to the present invention is as described above.The units are arranged in a flat manner, which makes it thin and portable, and also shortens the signal wiring route. -It is now possible to eliminate activation.

Next, a detailed explanation will be given of each unit mechanism having the above-mentioned arrangement. First, a description will be given of the lens driving section 6 that moves the collapsible lens barrel 2 of the exposure unit ioo K back and forth.

FIGS. 2(a) and 2(b) are side views of the lens barrel 2, and FIG.
a) (b) are front views of the lens barrel 2, and Figure 84 is a side view of the lens barrel 2 taken from a direction perpendicular to Figure 2. Figure 0 mainly depicts the parts necessary for explanation; is omitted.The lens barrel 2 is in a sunken position when it is being carried (when not photographing), and there is a sliding door-type lens cover 101 on the front of the lens barrel 2, which protects it from dust and protects it from dust when it is being carried. Figures 2(a) and 4 show this state.When taking pictures, the cameraman slides the lens cover 101 with his finger in the direction of the arrow.
By moving the lens cover 101 in the direction of the arrow, the switch M-8W (not shown) is turned on, and the motor is driven in the opposite direction (counterclockwise direction) to extend and project the lens barrel 2. First, the operation of the lens will be explained. I do.

Is lens barrel 2 the 0 mount attached to mount 21? (2) has a structure that allows it to be moved up and down along the inner wall of the main body frame 1020. The mount 21 is provided with two pins ρ in the diametrical direction.
A pair of bins ρ fitted with 03 are provided with a pair of 5-shaped levers 104 on the outer wall of the main body frame 102, and a spring 106 is applied to the 5-shaped lever 104.
The spring 106 is always biased in a direction to push down the lens barrel 2 via the five-figure lever 104 and the pin 4.

Also, one arm of the L-shaped bar] 04 is engaged with the bottle n, and the other arm is engaged with the slide plate 107. A bottle 108 is implanted in the slide plate 107, and the bottle 108 is embedded in the slide plate 107. is engaged with a lever 109. The lever 109 pivots around a shaft 110, and is rotated by a spring 112 as shown in FIG.
The bottle 1 provided on the lever 109 is biased in one counterclockwise direction by
11 is in contact with a cam 113 in the shape of a bead.

Now slide the lens cover 101 to open it 113
As the A cam 113 rotates once in the counterclockwise direction, the lever 10 comes into contact with the cam 113 and the pin 111K.
9, it swings in the direction of the hour hand about the shaft 110 and pushes down the slide plate 107 (Fig. 3 (a)). Counter-hour hand direction I! Figure 4) Rotate K,
The mount 4 and the lens barrel 2 attached to it are made to protrude through the bottle ρ. The cam 113 rotates once and returns to the initial position, and then loses the driving force that causes the mount 21 to protrude, and the spring 106 causes the mount 21 to return to the sunken position, but the mount 21 remains at the highest point of the protrusion. It will lock just a little closer.

This lock position is the lens position where photography is possible, as shown in Figure 2 (b).
1, FIG. 3 (bl shows this state.

There are three claws 23a extending outward from the mount 21.

The one-sided frame 102K on which Z3 b and Z3 c are fixed has fixed claws 23 a and 23 b.
, 23 c, and movable claws 121 m and 121 b that slide into and out of the holes.
, 0 movable claw 1214 with 121C, 121'b
, 121a are fixed claws 23 m, 23 b,
It is designed to mesh with 23c.

The movable claws 121a and 121b are attached to a claw holder and a fitting 122, and are attached to a lever 124 with some flexibility by means of a pivot 123. The lever 124 is biased in the lower left direction K (FIG. 2(b)) by a spring 130.

On the other hand, the movable claw 121C of 1113 is fixed to the claw mounting metal fitting 125. A pin 126 is installed in the claw mounting bracket 125, and a separately provided lever 127 pivots around a shaft 128, with one end connected to the pin 126 and the other end connected to the lever 124.
The lever 127 is urged by a spring 129 in the direction I11 (FIG. 3(b)).

That is, the movable claws 121a and 121b are moved by the spring 130, and the movable claw 21o is moved by the spring 129.
The claws are biased in the direction of protruding inward from the main body frame 102.

The tips of the fixed claw and the movable claw 121 are each tapered, so the movable claw 121 is temporarily retracted by the fixed claw while the mount 21 is protruding, and is movable again after the mount 21 is protruded. The pawl 121 protrudes and engages with the fixing pawl to fix the mount 21 in a three-point supported manner.

When you finish shooting and push the sliding door type lens cover 101 in the closing direction, the lens cover 1 will open as shown in Fig. 2 (1)).
Claw 124 engaged with protrusion 1011 provided on the right end surface of 01
1 to push the lever 124 to the right. Since the lever 124 is urged diagonally downward by the spring 130, the sliding plate 1241, which is a part of the lever 124, slides on the stepped cam 1021 provided on the camera body, and the lever 12
4 moves rightward along the step cam 1021K and also moves slightly downward. When the constant/amount lever 124 moves to the right, the protrusion 101 of the lens cover 101
1 is disengaged from the claw 1241 of the lever 124, and the lever 124 is about to return to the initial position by the spring 130. The lever 124 is pressed by the lens cover 101, and returns to the initial position just before the lens cover 101 opens. Return.

In the process of moving the lever 124 to the right, the movable claw 121
Both are retracted from the inside of the main body frame 102, and the mount 21 and the lens barrel, which are biased by the spring 106, move to a sunken position, and the lens cover 101 is positioned in front of the mount 21 and the lens barrel. It will be maintained.

What has been explained above is the retractable barrel, but next we will discuss the data recording mechanism 3, which is also located in the exposure system unit 100.
I will explain about this. The data recording mechanism 3, which is an optical system that records data such as date and time on one corner of the film screen, has a short length in a thin camera, making it difficult to increase the optical path length, and it also requires a collapsible lens barrel. In the camera used, there is a lens barrel or a lens barrel guide until the lens barrel is submerged and before the film is inserted, making it even more difficult to assemble the lens barrel.

Fig. 5 shows an enlarged cross-sectional view of the data distribution part, and the book is designed to be printed diagonally through the gap in the main body frame 102, which is positioned so as to cover the front surface of the film P.
The liquid crystal LCD (1) is illuminated from behind by a lamp B, which is bound by a transparent resin member blade such as acrylic and a lens 31. In general, the back side of the film or KL, and if it is included, the lens 31 is used. The liquid crystal x, cD(I) plane is provided perpendicularly to the optical axis of the
Since this camera imprints phrases from the film emulsion side, a considerable slope α is provided, and at the same time, a corresponding slope β is provided for the first side of the film. If the general busyness is α and β, the conditions for normal shooting will hold, and the conditions for conclusion will be good, but the magnification will be different.
In this camera, each point 101 on the surface of the liquid crystal LCD (1) is approximated on the surface of the film 2 by approximately converging α-β and covering the depth of focus. Also, by doing this, the liquid crystal LCD (11
The projection magnification of each point on the surface is different, so the liquid crystal
(1) Since the image of the surface will be transformed and projected,
The character shape on the liquid crystal LCD (I) surface was deformed in advance so that an appropriate image of FIG. 1IiigII was formed on one surface of the film.

In addition, a supporting portion 325 is provided to properly support the lens 31 by protruding a portion of the resin member 32Fi provided with the surfaces 322 and 323, and the lens 31 is fixed in the correct position using no-komi or adhesive. 0 resin parts (
A diaphragm plate is provided on the exit surface 324 facing the lens 31 to improve resolution and increase the depth of focus to obtain a good focal length.This data recording mechanism is installed in a three-piece camera dark box. Therefore, a liquid crystal display (LCD) is provided on the surface of the control system unit 300 on the outside of the camera, so that the cameraman can read the same information as the information being photographed.

The liquid crystal LCD (1) and the U/P L were connected to the adjacent control system unit (300) by extremely short wiring.

Next, the mechanism of the drive system unit 200 will be explained.

This camera uses a single motor M that rotates forward and backward, and when the motor M rotates in the reverse direction, the collapsible lens barrel is extended and the shutter is wound up, and when the motor M rotates in the forward direction, the film is wound. , first the film feeding section 5
I will explain about this. FIG. 6 shows a front view of the film feeding section, and FIG. 7 shows a side view (cross section of main parts) thereof.

The rotation of gear G1 attached to the motor M shaft is caused by gear train G2,
The gear 04 portion, which is transmitted to the gear G4 via the gear G3, serves as a clutch portion that switches the power transmission depending on the direction of rotation. A movable gear mounting plate 20 is provided on the G4 axis, and a spring member 202, which is a biased leaf spring, is provided between the -wheel G4 and the gear mounting plate 201. Gear mounting plate 20
1 K has gear shafts 203 and 204 fixedly installed, and gears G5 and G6, which are in a meshing relationship with gear G4, are rotatably engaged with the gear shafts 203 and 204, respectively.0 Now, the motor M is reversed. When the gear 04 rotates in the counterclockwise direction (Fig. 6) 1, the friction of the spring member 202 causes the gear mounting plate 201 to swing counterclockwise around the axis of the gear G4, and meshes with the gear G4. Gear G6 is now gear G
The rotation of the motor M is transmitted to the gear 08 via the gear G6. Also, when the motor lock rotates forward, the rotation of the motor M is transmitted to the gear G4. The plate 201 also swings in one direction, and the gear G5 is replaced by the gear G7.
The rotation of motor M is caused by gear G via gear G5.
In the state where the 0 gear G5 transmitted to the gear 7 is engaged with the gear G7, the engagement between the previous gear G6 and gear G8 is broken.

A gear 11 is provided coaxially with the gear G7.
The zero gears 11 and 12 meshing with the gear 12 are helical gears or worm wheels, and bend the rotating shaft by 90 degrees. A pin 52 is embedded in the gear G12 shaft 51,
The zero-force pull member 53, which has a couple member 53 that loosely fits on the shaft 51 and moves back and forth along the pin 52, is pushed leftward by the spring 54, which pushes the end of the film take-up shaft 14 of the film cartridge 1. A coupling connection is made with a joint part 15 provided in the section.

Further, the opening/closing shaft 144 of the rear cover 143 of the camera body is
A cam plate 145 is provided at the end of the 0-opening/closing shaft 144 which integrally rotates with the opening/closing of the progeny, and a lever 147 whose rotation axis is the shaft 146 is provided separately. Lever 14
One end of 7 engages with the cam end surface of the cam plate 145, and L//<
The other end of -147 engages with the flange 531 of the couple member 53. The lever 147 is a tensioned spring 148
It is biased in the direction of the hour hand (Fig. 7) #.

If the rear cover 143 is now -1, the cam plate 145. rotates [
Accordingly, the lever 147 rotates to the right, and when the rear cover 143 is opened, the lever 147 can be easily removed and installed. Also cartridge 1
After loading, when the rear lid 143 is closed, the cam plate 145 rotates, the lever 147 rotates in one direction counterclockwise, and the joint 15 of the cartridge l is coupled to the couple member 53, The rotation of the motor M in the forward direction is performed by the gear train G1.
The signal is transmitted via G2, G3, G4, G5, G7, Gll, and G12, and the film is wound.

Next, the exposure drive unit 4 will be explained. @Figure 8 is a schematic layout diagram for explaining the mechanism. In the figure, the lens barrel 2 is of a collapsible type, so the exposure drive unit 4 and the lens barrel 2 are mechanically separated, and the power for opening and closing the shutter is transmitted only when the lens barrel 2 is protruded. It is a mechanism.

The diameter portion 5 of the lens barrel 2 is normally covered by a shutter blade, and the shutter blade 26 a is symmetrical.
The shutter, which also serves as an aperture, is opened and closed by the symmetrical movement of the shutters 26b and 26b. That is, the shutter blade 26a.

26b rotates around rotational shafts 261m and 261b, and is biased by springs 27a and 27b in a direction to close the shutter blade. Shutter blade 26
There are elongated holes 262a and 262b in the shape of a cam for power transmission in a and 26b, respectively, and a pin provided in a part of the lever of a separately provided shutter blade drive member.
81 is loosely fitted. The shutter blade drive member Z is biased counterclockwise around the center axis 282, and the protrusion 28 is attached to a part of the other lever.
3 is provided. An intermediate member 4 is provided on the outer wall of the lens barrel 2 so as to be in contact with the protrusion 283 and to be movable up and down. Now, when the intermediate member 4 is pushed upward from the outside of the lens barrel 2, the shutter blade drive member 28 rotates in the rainbow direction about the central axis 282 [7. As the shutter blades 281 move to the right, the shutter blades 26a and 26b rotate symmetrically against the springs 27a and 27btC to open the shutter diameter portion 6. The exposure drive section 4 performs shutter exposure by pushing the intermediate member 4 with the lens barrel section 2 protruding, and controls the amount and duration of the push to control the aperture diameter and opening time. .

The exposure drive unit 4 is designed to control the opening time using two magnets. The combination magnet Mag 1 is a magnet for opening the shutter, and the magnet Mag 2 is a magnet for closing the shutter. In other words, the shutter setting is completed.

The intermediate member 4 of the lens barrel portion 2 is in a position where it is in relative contact with the plunger 41 of the exposure drive portion 4a with the lens barrel protruding. The plunger 41 can be moved up and down by the guide 14 children. A tip 421 of a lever 42 is engaged with a flange 411 provided on the plunger 41 . Lever 42
The pivot shaft core 142 is used as a swing shaft, and the pivot protrusion 423 is attached to the other end of the lever.
is the provision. There are also two levers 43 and 44 with the axis 143 as a swing axis. The lever 43 has a groove 431 that holds the protrusion 423 between them.

Further, the lever 44 is provided with a rotating shaft 441 and a rising portion 442, and a claw member 46 is provided on the rotating shaft 441, and the tip claw portion 461 of the claw member 46 engages with the rising portion 432 of the lever 43. , is biased in the direction of the hour hand about the rotating shaft 441, and one end of the claw member is in contact with the rising portion 442. The lever 43 has a spring 43a, and the lever 44 has a spring 45.
, the lever 43 is biased in the hour direction, the lever 44 is biased in the counterclockwise direction, and the spring 45 is biased against the springs 43a and 27.
It has the power to overcome a, 27 b, and 28 m.

The lever 44 has a protrusion 443, which is in contact with a cam plate 470 and a stepped cam portion 471.

47 cam plates that can be moved left and right, 14 tension springs
The protrusions 472, 473, and 474 on the n-cam plate 47, which is biased leftward by the n-cam plate 4, are not fixed. Button 4
The lever 473 contacts the governor 145 including the pallet and ankle gear, and the protrusion 473 contacts the lever 146 for shutter charging.
The cam 148 in the shape of a mag-ball is rotated in the opposite direction of the motor M that comes into contact with the cam 148 when the shutter is charged.
When the lever 146 rotates once in the counterclockwise direction, the lever 146 moves toward the shaft 147.
The structure is such that the lever 47 is set by reciprocating once with respect to the swing center at 17, and then pushing up the lever 47 to the right via the protrusion 472.

Now, when the camera's release button 500 is pressed, the shutter opening magnet Mag 1 receives a signal from the control system unit 300 and moves the plunger of the magnet Mag 1 to the left, making the center shaft 149 the center of rotation. The 5-shaped lever 48 swings in the direction of the hour hand, and the L-shaped lever 48 disengages from the protrusion 474 of the cam plate 47. When the lock is released, the cam plate 47 urged leftward by the tension spring 144 moves slowly to the left since the governor 145 is operating.

The lever 44 is rotated counterclockwise in the direction of the hour hand by the protrusion 448 that comes into contact with the cam 471 accompanying the moving cam plate 47, and the lever 43 engaged by the claw member 46 on the lever 44 is also rotated counterclockwise in the direction of the hour hand. do. The rotation of the lever 43 in the counterclockwise direction causes the lever 42 to move in the counterclockwise direction (2).Then, the plunger 41 engaged with the tip 421 of the lever 42 is pushed upward, and the shutter opens.

The relationship between the elapsed time for exposure and the shutter opening area is determined by the shape of the cam portion 471, the shape of the shutter blade, the moving speed of the cam plate 47, etc. A switch SSW or other detection member is provided near the zoom plate 47, and is structured to emit a signal corresponding to the aperture diameter of the shutter.

Next, when the control system unit 3000m2 control unit IC issues a signal to close the shirt, the magnet Mag2 is activated and the plunger is pushed upward.
The 5-shaped lever 49, which is biased in the direction of the hour hand with 50 as the center of swing, rotates in the direction of the hour hand with the movement of the plunger,
The rising end portion 491 of the lever 49 kicks the claw member 46 in the counterclockwise direction. As a result, the tip claw portion 4 of the claw member 46
61 and the rising portion 432 of the lever 43 are disengaged, the lever 43 is rotated by the spring 45 in the direction of the hour β↑, and the lever 42 is rotated in the direction of the hour hand via the protrusion 423, causing the plunger 41 to rotate. Push down - “close” the shirt.

After the shutter is opened and closed, the motor M rotates in reverse according to the sequence described later, and the lever 146 swings back and forth once around the shaft 147 to push up the cam plate 47 to the right, forming an L-shape, and the bar 474 The lever members 42, 43, 44 and the claw member 41, which are engaged and return to the state shown in the figure, are also connected to the operation of the lever 146 by a return member (not shown), which restores the shirt to the charged state before opening. to return to.

Next, a description will be given of the program automatic exposure control adopted in this camera for exposure by the exposure drive section 4 described above. Figure 9 is a graph of this aperture and time in seconds □ Time tJ
The diaphragm/shutter blade that started opening is A at time t.
Following the n-line, the aperture diameter is equivalent to, for example, V8. Then, at times t and t, the IC line maintains the aperture diameter of r8, and after the time tell, the aperture is again sharpened and follows the CD line, resulting in the aperture diameter corresponding to, for example, P4. Here, the DB line again maintains the aperture diameter of F4. The diaphragm/shutter blades operate as described above to expose the film surface.
Based on information from a photoelectric element such as a separately provided C4S, the seven blades are closed during the opening of the shutter blade. Figure 10(a) corresponds to the shutter blade operation in Figure 9. The 0 photodetector, which is a photometric circuit, is shown in Figure 10 (
bl K Two light receiving elements P C (B, ), P C (R1) with different γ; 1.0 and γ = 0,5
Use.

Switching of the light receiving elements p c (R,) and P c (Rs) is performed by the detection section 88 of the exposure drive section 4 shown in FIG.
First, at time t0 when the shutter starts opening, the switch P on the light receiving element PC(B-v) side is activated by W1.
8W2 (IN L6) Then at time t, the light receiving element P C
At time t, the switch P8W 1 on the (R, ) side is turned ON, and the switch P8W 2 is turned OFF, and at time t, the switch P8W 1 is turned OFF, and the light receiving element pc(~)@
At time 0 1, when the side A edge 1iIs is ON, the switch p8W 1 on the light receiving element PC (R, ) side is ON.
'Then, the switch P8W2 turns OFF. Since such switching is not performed, the capacitor C for storing optical information is charged. One terminal of the comparator COMF is divided and set according to the ASA sensitivity of the film, etc., and the other terminal is charged with the above-mentioned capacitor. A charging voltage is input to C, and at time t4 when both voltages become equal, a closing instruction is issued and the shutter closes. In the conventional automatic exposure control method, the aperture of the shutter that also serves as an aperture continuously expands, and photometry is performed. When a signal is output from the device, it closes, and generally, the r value of the 04-photoelectric element of the photometric circuit is set to 0.5, and the amount of incident light from the subject is 1.
When mv changes, the shutter speed changes by 0.51V and the aperture changes by 0.5BY. Therefore, even when photographing a bright subject, it is not possible to take pictures with emphasis on the aperture effect.
/T is 5. This method requires a higher accuracy of focus adjustment since the focal length ranges from 6/250 to 8/125 and photographing is not performed with emphasis on the aperture effect.

The program automatic exposure control method adopted for this camera is (
1) Take into account camera shake and use a linkage range that is as wide as possible. 0. (2) When using the conventional automatic exposure control method to fire a strobe, the flash was fired immediately after the shutter began to close. Therefore, the drawback of electrical control, which is that it is difficult to capture this moment, is overcome, and the time of light emission can be determined relatively easily, making it suitable for cameras with built-in strobes, which is a new feature. FIG. 11 shows a photometric circuit which has been further improved to correspond to the shutter blade operation shown in FIG. In the photometric circuit shown in FIG. 10, two light receiving elements with different r values are used, whereas one light receiving element P with r-0.5 is used.
C (R2) is used as the circuit shown in FIG. 11(a), and the switching circuit P88 for charging the capacitor C for photometric information storage performs switching as shown in FIG. 11(b). Fine pulse-like ON-OFF alternating switching is performed between times 1 and 1 and between times 1 and 1, and r = as explained in Fig. 10.
1. It is designed to have the same photoelectric effect as the photodetector P C (R1) of No. 0.

Finally, I will explain the control, warning, and display circuits of this camera. Figure 12 shows an outline of the control circuit of this camera, which is controlled and driven by an IC unit with one or more chips, and is capable of discharging large currents as a power source for motors and strobes. Battery BAT 1 The battery BAT 2, which is suitable for long-term discharge of minute currents as a power source for timers, memory, etc., is used as a power source to control and operate processes such as auto-loading, film feeding, lens barrel protrusion, and photography. . Note that although this camera has two power supplies depending on the application, it is also possible to share battery BAT1. The control, operation, display, etc. of these will be explained in sequence below using time charts and the like.

First, the shooting sequence will be explained. Photographing is possible after the lens barrel is advanced and protruded as will be described later, and FIG. 13(a) shows the photographing seek/stimechard. The release button has two steps and has two built-in switches 81 and 82.

First, by pressing the first stage release and turning on the switch 81, the power supply switch (B, C) of battery BA〒1 is turned on.
When it is detected that the battery BAT 1 is exhausted, a warning is issued by the light emitting diode LBD K. Also,
After the above power check, the light receiving element Cds performs a subject brightness check (t, , C), and if the brightness is below a preset brightness, a light emitting diode LED issues a warning. Battery BA'l' 1 performs subsequent operations such as film feeding, etc. When battery capacity is insufficient, the release is electrically locked and photographing is prohibited. A flowchart of this warning display is shown in FIG. 13(b), and a display map of the warning display is shown in FIG. 13 1cl. In order to make effective use of the limited camera space, a battery drain warning, low brightness warning, and self-timer display (described later) are integrated into a single LR.
Do this by sharing D. Below are Figure 13 C11) and 13
The battery exhaustion warning and low brightness warning will be explained according to the diagram (Q).

First, when the switch '1 is turned on, a power supply check is performed. Compare the preset voltage * (setting value 1 and setting value 2) with the voltage of battery BAT 1, and set the range H,
Check and memorize where it is located between M and L. At this time, if the voltage of battery BAT 1 is L, it is assumed that it does not have the ability to execute the following sequence, and photography is prohibited. If the voltage is Hl or thin, then a brightness check (t, , C) is performed. If the brightness value is less than the preset value (setting value 3) (NG), the LID
lights up to issue a low luminance warning. If the result of the battery check is M and the test result is a set value of 3 or more (OK), the LBD flashes and a low battery warning is given to notify the photographer that it is almost time to replace the battery. The low brightness check is repeated until the second stage release is pressed and the switch 82 is turned on. Low brightness [1! ' warning is displayed with priority over the low battery warning.

As mentioned above, the low brightness warning and the low battery warning can be
It can be displayed by ID. Note that when the voltage of battery BAT 1 is Hf1 brightness is equal to or higher than the set value 3, and when the voltage of battery BAT 1 is L regardless of the brightness, 3D remains off, but the first By pressing the shutter release button and pointing the light receiving part toward a dark place, or by covering it with your hand,
Since the camera enters the low brightness warning mode, it can be easily determined whether the voltage of the battery BAT 1 is equal to or higher than the set value 2 (that is, photographing is possible).

The shutter is released by pressing the second stage release and turning on the switch S2. At this time, when the self-timer switch 8T is ON, the light emitting diode LR, which is shared with the low brightness/battery warning, is activated for about 10 seconds (tIg).
The shutter is released after D is in the self-mode AL state. The blade opening of the n-shutter is performed by a magnet Mag. When in data recording mode, from the shirt open
After e seconds, the illumination lamp LAMP is preheated tp and then 1
．． , lights up for seconds.

The closing blade of the shutter is moved by the magnet Mag 2, and when data recording is completed, the motor M is first reversed (cc
w) When the shutter is charged and the shutter charge completion detection switch 8C-2 changes from ON to OFPK, the film is wound forward (cw) and the perforation detection unit (pw), which will be described later, is activated. When one frame is detected, the motor M changes from normal rotation (CW) to reverse rotation (CCW) which applies a brake, and the correct one frame is fed.

FIG. 14 shows an autoloading chart. Load film on the back of the camera! This is done by opening 143 and loading cartridge 1. The switch back cover switch 8B is activated by opening and closing the camera back cover 143, and when the back cover 143 is opened, the switch liB is turned on.As with the 141-step release 81 ON in the shooting sequence, the battery 11 is activated. Perform a battery check for BAT1. While the back cover 143 is open, the battery BAT
When 1 is set to M, the light emitting diode LID warns of low battery power.Similar to the Ota photography sequence, a battery check using 1 low brightness warning can also be performed.

When the cartridge 1 is loaded into the camera and the back cover 143 is closed, the winding drive system of the motor M is power-coupled with the film winding shaft 14 of the cartridge 1 as described above, and the switch 88 turns FiOFF and the 0 battery BAT1 is turned off. voltage is L
In this case, the film winding motor N will not operate. If battery BAT 1 is Mpa or H, motor M will rotate forward (t4) approximately 100m5 after closing cover 1.
CW) Start film feeding.

At the opening of the cartridge 1, there is a perforation detection section consisting of a microswitch that detects perforations at the end of the film, and detects the amount of film conveyance. In general cameras, the amount of film advance for one frame is detected or regulated by one or half a turn of the sprocket that engages with the perforation, but this camera directly detects and controls the number of perforations.↓ The amount of feed is regulated. This camera counts the number of perforations, stops feeding after 3 frames, and finishes autoloading. That is, immediately after the forward rotation (CW) of the winding motor M stops, Ktl-1, the reverse rotation (caw) of the motor M is performed for a short time of about 20 m5 (tb), and the inertia of the motor M prevents an inaccurate film feed amount. 〇In addition, when the back 11i 143 is closed without loading cartridge 1, the motor M rotates forward (CW) for about 2 seconds and then stops even if the bar foration signal is closed.
During autoloading, which is 0, photographing, extending and protruding the lens barrel, and switching the liquid crystal display mode are prohibited.

Next, the operation of the lens barrel will be explained. As already mentioned, opening and closing of the lens cover 101 causes the two lens barrels to protrude or retract. FIG. 15 shows a time chart for this. Shiy, r cover 101
vm< and main switch M-8W ON l,, BAT
] When it is detected that the voltage of the battery BAT is L as a result of the 0 battery check,
Motor M does not operate.

Shooting is prohibited with the lens barrel 2 retracted - If the voltage of battery BAT 1 is M or H, the lens barrel 2 is extended forward (CW), and the lens barrel 2 is extended. 2 protrudes to a predetermined position, the lens position switch 8C-1 provided on the lens barrel 2 part is turned OFF, and the motor M is stopped by applying a dibrake during tb in the same way as for film feeding, and the lens barrel 2 is no longer extended. The lens is now in a position where it can take pictures. When the lens cover 101 is closed after photographing, the lens barrel 2 is collapsed by a spring 106.

Next, the liquid crystal display will be explained. There is a liquid crystal display board LCD (II) for monitoring on the outside of the camera. There is also a main liquid crystal LCD (1) in the data recording section. A liquid crystal LCD (11) for recording in the data recording section, so that the mode can be determined from the outside. LCD monitor I, CD (connected electrically in parallel with It). There are 3 display modes: calendar, clock, and film counter. Button PB!
The relationship between 9C, 8D and mode display is as shown in Figure 16 of the FIFM, and the display mode changes as shown in the figure by operating the button PB. The explanation will be given below according to FIG. 16.

First, each time you turn on the SD, the display mode switches in the following order: Calendar 1 → Hour hand → Counter → Calendar J. In addition, in this embodiment, when in the calendar/hour hand mode, the display mode switches automatically. The camera automatically enters data/recording mode, and each time a photo is taken, the LAMP lights up and the data at that time is recorded. When the counter/display says "0", the camera enters data recording prohibition mode and no data is recorded.Data In order to clearly indicate that the camera is in recording mode, the letters RPC are displayed on the monitor liquid crystal panel.

You can switch the display mode by turning on 8D, but you can also switch to a counter display while turning on 8C in calendar/clock mode. While selecting a mode, you can check the counter directly without going through the hour hand mode.Turn off O20 to return to the original display mode.Turn on 08B. data can be corrected. I will omit the detailed explanation here, but in the same way as a general digital watch,
The combination of the 8D and 8C switches allows the date and time to be corrected.

Next, I will explain the relationship between one shooting sequence and the counter.Unlike conventional general mechanical counters, the 0-shot counter is designed to actively notify the photographer of the cartridge and film feeding status. can. In this embodiment, a case is shown in which a film capable of photographing 24 frames is placed inside the car storage I P3.

First, when you open the back cover, the counter is automatically set to the initial value (O in this case), just like a conventional mechanical counter.0 Next, when you close the back cover and autoloading is performed, the counter is set to l. Display [2, the following shooting is possible 0
Below, the counter increases by one each time one shot is taken. When the last frame in the row is taken, the film is fed until the perforation signal disappears, and the shot film is completely wound. 0 At this time, in order to clearly indicate the end of the film, change the color/re indication to m.
- to prohibit shooting (release lock).

The above is the counter display when normal photographing is performed, but the display in a special case will be explained next.

First, if auto error is performed without a cartridge loaded, the motor will rotate forward for 2 seconds and stop as described above, but at this time, the counter will display 00.
Therefore, it is possible to easily know whether a cartridge is present without installing a switch on the @ to detect the presence or absence of a cartridge or opening a window for confirmation on the back cover. If you take a picture in this condition, the motor will operate for a certain period of time and then stop.
This allows you to take so-called aerial shots. No matter how many times I empty the machine, the counter display remains OO, indicating that there is no cartridge. ◎Next, even if I close the back cover when the voltage of battery BAT1 is L, the motor does not operate, At this time, the counter remains at 0, indicating that AL has not been performed. At the same time, photography in this situation is prohibited.

Furthermore, if the film is not fed due to some minor reason during normal shooting, that is, if there is no perforation signal for a certain period of time, the counter display will change to m.
-, and further photography is prohibited. Here, the display when Sae-frame shooting ends and when a feeding error occurs during shooting are the same, but it is also possible to display this separately (for example, it is possible to display characters such as B or END at the end of Sae-frame shooting. ).

In addition, in this embodiment, since the monitor liquid crystal panel is used in common with the calendar and clock, the characters ``ixp'' are displayed when the counter is displayed to make it clear that the counter is displayed. Control, warning, and display of this camera are performed by the circuit shown in FIG. 12, which constitutes the control system unit 300. As already shown in FIG. 1, the control system unit 300 includes an IC for drive control. Electrical components such as batteries and capacitors are centrally located l1, and a display and operation panel is provided on the front. Therefore, the wiring for this camera that is connected to other isolated units is limited to the motor M that is the power source for various operations, the magnets Mag 1 and 2 for opening and closing the shutter, and several switches for detection. .

Therefore, with a new arrangement like this camera, it is easy to detect and repair faults, and it is possible to escape from the various problems caused by the complicated units, mechanisms, and wiring of conventional cameras! Ta0
