DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera, and more particularly to an improvement of a small camera using a film cartridge.

[0002]

2. Description of the Related Art When not in use, an IX240 type film cartridge in which a photo film is entirely housed in a cartridge body to facilitate loading into a device such as a camera, and after loading, a spool is rotated to send out the photo film from the cartridge body. Is manufactured and sold by the present applicant and the like. The photo film housed in this film cartridge is one time smaller than the conventional 135 type photo film.
Since the top of the film is small and the film base is thin and hard to wind,
It is smaller than 35 types of patrone.

[0003] Cameras and film units with lenses are
Miniaturization is being promoted to improve portability, etc.
Some cameras using five types of film patrones are about the size of a cigarette box. Cameras using the IX240 type film cartridge are of the same size, but the size can be further reduced by optimizing the internal component arrangement.

[0004]

However, although a small camera is excellent in portability, it is difficult to hold the camera for actual photographing, and the photographing lens or the strobe light emitting portion is caught by a finger, and the photographing fails. May be done. In order to solve this, a projection is provided around the photographing lens and the strobe light emitting portion to warn the photographer of finger-holding, but a protrusion is provided around the photographing lens and the strobe light emitting portion. However, there is a problem that the camera design is not preferable.

In Japanese Utility Model Application Laid-Open No. 60-60731, a slide case for covering a photographing lens, a strobe light emitting portion, and a shutter button is provided on a camera body in which a photographing mechanism is incorporated, thereby exposing the photographing lens and the strobe light emitting portion. A camera has been proposed in which a slide case is used as a grip for holding a camera body when the slide case is slid in a direction in which the slide case is moved. However, such a slide case of a camera has a problem that dust and the like easily enter between the camera body and the slide case because the strobe light emitting portion is exposed by an opening provided in the center.

For this reason, a slide case is provided on the camera body, and an unused position covering the photographing mechanism and the like, a photographing position exposing the photographing mechanism and the like, and a cartridge replacement position where the film cartridge can be replaced are further provided. In between, there is a demand to slide the slide case on the camera body. However, if the slide case is simply slid to the above-mentioned positions on the camera body, the following problem arises when a IX240 type photo film cartridge is used because the light shielding cover is built in. is there.

That is, when the photographic film is not completely wound into the film cartridge, the film is present at the film entrance, so that the light blocking cover for opening and closing the film entrance is in the open position. If the slide case is slidable to the cartridge replacement position in this state, the photographic film is exposed when the light-shielding lid is opened by mistake. To prevent this,
It is necessary to regulate the movement of the slide case in the opening direction when the light shielding cover is not at the closed position. Therefore, a means for restricting the movement of the slide case in the opening direction is required.

Further, by closing the light-shielding lid in conjunction with the movement of the slide case in the opening direction, it is not necessary to separately close the light-shielding lid using a driving means such as a motor.
Therefore, the number of parts such as the motor can be reduced, and the size can be further reduced. However, simply linking the operation of moving the slide case in the opening direction with the interlocking member and the operation of closing the light-shielding lid may cause the slide case to move in the opening direction if the photo film is not completely wound into the film cartridge. The movement forcibly closes the light shielding cover to the closed position. For this reason, there is a problem that an excessive force is applied to the light-shielding lid and the light-shielding lid opening and closing mechanism, and the light-shielding lid and the light-shielding lid opening and closing mechanism are damaged.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is possible to easily and safely close a light shielding cover in conjunction with movement of a slide case.

FIG. 2 is an external perspective view showing a state when a camera 2 embodying the present invention is used. Camera 2
Is composed of a camera body 10 and a slide case 12. The camera body 10 is a thin box-shaped exterior case 2
Reference numeral 2 denotes a movable barrel 4 for holding the taking lens 3, a strobe light emitting unit 5, a finder 6, a photometric light receiving window 7, and a distance measuring light emitting window 8, a distance measuring light receiving window 9 which constitutes an active distance measuring device, Is provided. Further, the end of the outer case 22 opposite to the side to which the slide case 12 is attached has rounded front and rear corners, so that it is easy to hold. The outer case 22 is formed of plastic or a lightweight metal such as aluminum or titanium.

On the back of the camera body 10, a liquid crystal display 20 for displaying the date, the number of shots, the shooting mode, and the like,
Below the liquid crystal display 20, a panel switch 21 for changing, setting, and switching a date, a photographing mode, and the like is arranged. Note that the liquid crystal display 20 may be made larger, and a touch sensor having the same function as the panel switch 21 may be provided at an arbitrary position on the liquid crystal display 20. According to this, there is no irregularity on the back surface of the camera body 10, and the design becomes simple.

A projection 24 for electrically detecting that the slide case 12 has come off is provided on the case mounting end side of the rear surface of the camera body 10. This projection 24
Is attached to a slit 22d of the exterior case 22 by a spring plate (not shown) so as to be freely retractable. The spring plate forms a switch contact piece, and the switch contact piece electrically detects whether or not the slide case 12 is attached to the camera body 10.
This detection signal is sent to the control unit, and the power is turned off when the slide case 12 is detached from the camera body 10. Therefore, the movable cylinder 4 is collapsed by turning off the power.

The slide case 12 is slidably mounted so as to cover the outside of the camera body 10, and is formed in a thin box shape with one end opened.
Further, a shutter hole 13 in which the shutter button 11 is arranged is formed on the upper surface.

As shown in FIG. 3, a shutter button mounting plate 14 is provided on the upper back surface of the slide case 12, and the shutter button mounting plate 14
1 is attached. The shutter button mounting plate 14 has a first locking edge 15 and a second locking edge 1 as locking portions for stopping the slide case 12 at each position.
6, a first locking projection 17 and a second locking projection 18 are formed.

The slide case 12 is formed to have a length (ほ ぼ / 3L) that is approximately ／ of the total length L in the sliding movement direction of the camera body 10, and as shown in FIG.
In the non-use position, the total length L of the camera body 10 is approximately 2
/ 3. Thereby, the camera 2 when not in use is a neat design, and the camera 2 appears smaller than its actual size. In addition, since the slide case 12 does not have a large opening or the like except for the entrance opening of the camera body 10, dust and the like hardly enter between the slide case 12 and the camera body 10.

The slide case 12 is integrally formed of, for example, a lightweight metal such as plastic or aluminum or titanium. As shown in FIG. The movable cylinder 4, the strobe light-emitting unit 5, the liquid crystal display 13, and the like, which cover the moving cylinder 4, are slidable between non-use positions as shown in FIG. During this sliding movement, as shown in FIG. 2, the shooting position at which the moving barrel 4, the strobe light emitting unit 5, the liquid crystal display 13, and the like of the camera body 10 are exposed, and as shown in FIG.

At the photographing position, the slide case 1 is moved by the photographing position lock device to be described later during the sliding movement.
2 is automatically stopped. The slide case 12 is automatically stopped at the safety lock position by a safety lock device described later when the light shielding cover 49 (see FIG. 9) of the film cartridge 39 is not closed. As is well known, the light-shielding lid 49 is provided for the photographic film 40.
Opens and closes the film doorway for entering and exiting. When the light shielding cover 49 is closed, the slide case 12 is not stopped at the safety lock position by the safety lock device. In this way, by making the slide case 12 slidable on the camera body 10, the camera 2 can be made compact when not in use to improve portability, and has an appropriate length when photographing. Can be easily held, and a finger can be prevented from being caught on the photographing lens 3, the strobe light emitting unit 5, and the like.

In the exterior case 22 of the camera body 10,
As shown in FIG. 7, a base 23 is arranged, and components are mounted on the base 23 at a high density to reduce the size. An aperture 25 for defining an exposure range to the photographic film is formed in the center of the base 23, and a cartridge chamber 26 is formed at one end so as to sandwich the aperture 25.
However, a film winding chamber 27 is formed at the other end. Further, a lens barrel unit 28 is provided in front of the aperture 25.
Is attached. The lens barrel unit 28 includes a fixed barrel 29 and the movable barrel 4. The side wall 29a of the fixed cylinder 29 on the film take-up chamber side is formed in a cylindrical shape. When the fixed cylinder 29 is attached to the base 23, the film is wound using the cylindrical side wall 29a. The chamber 27 is closed.

When the power switch of the camera body 10 is turned on, the lens barrel unit 28 extends the movable barrel 4 to the front of the camera body 10 as shown in FIG. The moving cylinder 4 is stored. As shown in FIG. 8, a lens barrel drive motor 31 for moving the movable barrel 4 forward and backward and focusing is disposed on the lower right side of the fixed barrel 29. When the taking lens 3 is a zoom lens, the drive motor 31 is also used as a zoom drive motor.

As shown in FIG. 7, a photometric light receiving window 7 and a distance measuring light emitting window 8 of the camera body 10 are provided above the fixed cylinder 29.
At a position corresponding to the distance, the photometric light receiving section 32 and the distance measuring light emitting section 3
3 is attached. Further, a distance measuring light receiving section 34 is attached to a lower portion of the fixed cylinder 29 at a position corresponding to the distance measuring light receiving window 9 of the camera body 10.

In the film winding chamber 27 of the base 23,
A winding shaft 36 is mounted via a motor holder 35, and a motor 37 is built in the winding shaft 36. Further, a finder unit 38 is mounted above the motor holder 35.

As shown in FIGS. 8 and 9, a film cartridge 39 is loaded in the cartridge chamber 26. In the film take-up chamber 27, the photographic film 40 sent out from the film cartridge 39 is taken up by the winding shaft 3.
6 to be stored.

A bar code sensor and a spool sensor are incorporated outside or inside the upper surface of the cartridge chamber 26. The bar code sensor reads the contents of a bar code plate 41b that rotates together with the spool 41 of the film cartridge 39. The spool sensor detects the position of the notch in the bar code plate 41b of the film cartridge 39 to detect the rotational position of the spool 41. Further, a cartridge sensor is provided near the cartridge chamber 26, and detects whether or not the film cartridge 39 is present. These sensors are IX240 type cameras (manufactured by FUJIFILM Corporation, trade name "Epion 250") which are already manufactured and sold.
Z, 300Z ") and the like, and a detailed description is omitted, and in order to prevent the drawing from being complicated,
These illustrations are also omitted.

As shown in FIG. 8, a micro switch 42 connected to a control circuit in the camera body 10 is incorporated in an upper portion inside the outer case 22. When the slide case 12 is set at the photographing position, the micro switch 42 is provided above the operation button 42a.
The shutter button 11 is disposed at a position where the press-down protrusion 11 a is positioned, and the button 42 a is pressed via the shutter button 11. Shutter button 11
Is mounted on the slide case 12 via the shutter button mounting plate 14 so as to be freely pressable in the vertical direction, so that the button 42a of the microswitch 42 can be pressed only when the slide case 12 is slid to the photographing position.

The button 42a of the micro switch 42 is 2
Focusing and photometry are performed in the first stage that is turned on by lightly pressing, and shutter release is performed in the second stage that is turned on by being deeply pressed. When the micro switch 42 is turned on at the first stage,
The control circuit operates the distance-measuring light projecting window 8 and the distance-measuring light-receiving window 9 to measure the distance to the subject, and moves the taking lens 3 along the optical axis direction based on the measured distance. Focus is performed. Further, the control circuit simultaneously measures the luminance of the subject via the light receiving window 7 for photometry, and determines a shutter speed and an aperture suitable for the luminance. Micro switch 42
Is turned on in the second stage, the control circuit performs a shutter release based on a shutter speed and aperture suitable for luminance.

As shown in FIG. 9, an opening 26 a through which the film cartridge 39 enters and exits is formed in the bottom of the cartridge chamber 26, and the opening 26 a is opened and closed by a bottom cover 43. The bottom lid 43 has one end 43 a pivotally supported by the camera body 10 and is openable and closable. When the bottom lid 43 is closed so as to close the cartridge chamber 26, the cartridge chamber 2 is closed.
6 locked. This bottom cover 43 is
Can be opened only when is at the cartridge replacement position removed from the camera body 10.

That is, when the slide case 12 is slidably attached to the camera body 10,
Since the opening edge of the slide case 12 suppresses the end of the camera body 10, the opening of the bottom cover 43 is prevented. Therefore, the camera 2 does not require a lock mechanism for the bottom cover 43 that is linked to the opening of the light-shielding cover 49, so that the size of the camera body 10 can be reduced by making the bottom cover 43 thinner, and the cost can be reduced by reducing the number of components. The front and rear edges of the bottom cover 43 extend upward. By rotating the bottom cover 43 while holding the extended portion 43b between fingers, the bottom cover 43 can be easily opened.

As shown in FIG. 8, a drive gear 45 having a drive shaft 44 and a connecting gear 46
Are rotatably incorporated. The drive shaft 44 is engaged with the engagement hole 41a of the spool 41 of the film cartridge 39. The drive shaft 44 is integrated with a drive gear 45. The connection gear 46 is engaged with the drive gear 45, and is connected to the drive transmission mechanism of the camera body 10 when the bottom cover 43 is closed.

The drive transmission mechanism includes a motor 37 incorporated in the winding shaft 36 and a plurality of gear trains for selectively transmitting the rotation of the motor 37 to the winding shaft 36 or the driving gear 45 of the bottom cover 43. 47. Gear train 47
Is mounted on the bottom side of the camera body 10, and when the bottom cover 43 is closed, the connection gear 46 meshes with the final gear 48 at the end of the gear train 47.

The drive transmission mechanism includes a motor 37, a gear train 4
7, the spool 41 of the film cartridge 39 is rotated in the film feeding direction via the connecting gear 46, the driving gear 45, and the driving shaft 44, and the photographic film 40 is fed from the film cartridge 39. The photographic film 40 reaches the film winding chamber 27, and the leading end is wound around the winding shaft. At this time, the winding shaft 36 winds up the photo film 40 at a speed higher than the feeding speed of the photo film 40. Then, the gear train 47 cuts off the drive to the spool 41 and thereafter winds up the photographic film 40 only by the rotation of the winding shaft 36.

The final gear 48 of the gear train 47 is slidable in the vertical direction along the rotating shaft 48a, and is urged downward by a spring. Accordingly, when the teeth of the connecting gear 46 and the teeth of the final gear 48 collide when the bottom cover 43 is closed, the final gear 48 is pressed by the connecting gear 46 and slides upward. The bottom cover 43 can be closed without considering the gear stop position. Then, the final gear 48 is driven by the driving of the motor 37.
Is rotated, the final gear 48 slides downward by the bias of the spring and engages with the connecting gear 46.

As shown in FIG. 7, a battery storage case 50 is formed on the base 23 at a position above the aperture 25. Further, in front of the battery storage case 50, the strobe light emitting unit 5 and the battery lid 52 are attached via a mounting bracket 51.

As shown in FIG.
The slide case 12 is moved by the pop-up mechanism 55.
When is set to the shooting position, a pop-up is displayed and the camera becomes usable. The pop-up mechanism 55 is configured by disposing the strobe light emitting unit 5 on the mounting bracket 51 so as to be rotatable by a mounting shaft 56 at an angle of 90 degrees. Then, the strobe light emitting unit 5 is urged by the coil spring 57 in a direction to protrude upward. Therefore, when the slide case 12 is set at the photographing position, the pressing restriction by the upper surface of the slide case 12 is released, and the strobe light emitting unit 5 pops up by the bias of the coil spring 57. In the non-use position, it is pressed by the upper surface of the slide case 12 and is set in the retracted position.

A power switch 58 is provided so as to be linked with the pop-up of the strobe light emitting section 5. The power switch 58 is connected to a control circuit that performs various controls of the camera body 10, and is turned on when the strobe light emitting unit 5 pops up. Therefore, the strobe light emitting unit 5 pops up at the shooting position and the power is turned on,
The camera is ready for shooting at the shooting position. When the strobe light emitting unit 5 is set to the storage position, the power is turned off.

The battery cover 52 is provided with a mounting shaft 5 for the strobe light emitting section 5.
6 and is rotatably mounted on the camera body 10 as shown in FIG.
Between the upper surface and the closed position which is flush. And
As shown in FIG. 2, when the slide case 12 is in the shooting position, a part 52a of the battery lid 52 is
Is covered with the end. Therefore, the slide case 12
However, the battery cover 52 cannot be opened at the non-use position or the photographing position. Thereby, it is possible to prevent the battery from being accidentally replaced while the power of the camera 2 is turned on. When the slide case 12 is in the battery replacement position as shown in FIGS. 5 and 6 or the cartridge replacement position as shown in FIG. 3, a part 52 a of the battery lid 52 is covered by the end of the slide case 12. Because there is no such thing, it can be opened.

As shown in FIG. 8, a support shaft 60 is provided on the upper surface 26b of the inner wall of the cartridge chamber 26. The support shaft 60 is inserted into an engagement hole 41a (see FIG. 9) formed at the end of the spool 41 of the film cartridge 38.

A light-shielding lid opening / closing mechanism 6 for opening and closing the light-shielding lid 49 is provided in the mounting hole 26c at the upper part of the cartridge chamber 26.
2 are incorporated. As shown in FIG. 1, the light-shielding lid opening and closing mechanism 62 includes a light-shielding lid opening and closing lever 63 and a safety lock lever 64.

The light-shielding cover opening / closing lever 63 is
5, a first engagement shaft portion 66 and a second engagement shaft portion 67, and are integrated by a washer 68a and a mounting screw 68b. First engagement shaft portion 66 and second engagement shaft portion 67
Are integrated via the fitting portion 66b so that they do not rotate with each other. The first engagement shaft 66 has an engagement end 66a at the lower end. This engagement end 66
a is an engagement hole 49 at the end of the light-shielding lid 49 as shown in FIG.
a.

The drive lever 65 is rotatably attached to a mounting shaft 66c of the first engagement shaft 66. In the drive lever portion 65, a transmission engagement piece 65a is formed by bending. The transmission engagement piece 65a is
7 comes into contact with the engagement piece 67a, and the second engagement shaft 67 rotates clockwise. As shown in FIG. 3, when incorporated in the outer case 22, the drive lever portion 65 protrudes outside from a slit 22 a formed on the back surface of the outer case 22. Therefore, the sliding movement of the slide case 12 causes the end face of the slide case 12 to hit the drive lever portion 65 and rotate the drive lever portion 65 clockwise.

A first coil spring 69 is provided between the drive lever 65 and the first engagement shaft 66. The first coil spring 69 urges the drive lever 65 in a counterclockwise direction. I have. A second coil spring 70 is provided between the first engagement shaft 66 and the upper part of the cartridge chamber 26. The second coil spring 70 moves the first engagement shaft 66 counterclockwise (light blocking cover). In the closing direction). The urging force of the first coil spring 69 is weaker than the urging force of the second coil spring 70.

Therefore, when the slide case 12 slides toward the cartridge replacement position, the drive lever 65 also rotates counterclockwise by the urging of the first coil spring 69 as the slide case 12 moves. Further, since the first engagement shaft portion 66 is biased by the second coil spring 70, the first engagement shaft portion 66 rotates counterclockwise with the rotation of the drive lever portion 65 in the counterclockwise direction. If the photo film is not completely wound in the film cartridge and the film is present at the film entrance, the second coil spring 70
The light-shielding lid 49 (see FIG. 9) is rotated in the closing direction via the first engagement shaft portion 66 by the urging, but since the film is in the passage, the light-shielding lid 49 is not further closed. . On the other hand, the drive lever portion 65 is returned counterclockwise by the bias of the first coil spring 69, and is brought to the closed position shown in FIG.

As described above, since the light shielding cover opening / closing lever 63 is doubled by the drive lever portion 65 and the second engagement shaft portion 67, even when the film is not completely wound on the cartridge, the drive lever portion is opened. 65 is in the closed position. In this closed position, the drive lever 65
Does not protrude much. In addition, since it is in the closed position, it is difficult to forcibly rotate the light blocking cover in the closing direction by an external operation by grasping the tip of the drive lever portion 65. Therefore, it is possible to prevent the light shielding lid and the light shielding lid opening / closing lever from being damaged by an erroneous external operation.

That is, if the light-shielding cover opening / closing means is not integrated with the engagement shaft portion and the drive lever portion and the light-shielding cover opening / closing means is integrated, the film is pulled out of the cartridge into the camera as in the middle of photographing. In this state, the light-blocking lid is not closed due to the presence of the film, so that the drive lever unit also stops at an intermediate position. For this reason, there is a risk that the drive lever unit may be erroneously operated in the closing direction of the light-shielding lid. In this case, an excessive force is applied to the light-shielding lid and the light-shielding lid opening / closing means, which may be damaged. This can be prevented.

The slide case 12 is connected to the camera body 1.
When the slide case 12 is set to 0 and the slide case 12 is slid from the cartridge replacement position to the non-use position side, the end face of the slide case 12 pushes the drive lever portion 65 and rotates it clockwise in the drawing. Accordingly, the first engagement shaft 66 also rotates clockwise via the transmission engagement piece 65a and the engagement piece 67a of the second engagement shaft 67, and the light-shielding lid of the film cartridge is moved from the closed position to the open position. Is set to

A brush contact piece 71 is attached to the second engagement shaft portion 67 via an attachment piece 67b. A printed circuit board 72 is disposed above the cartridge chamber 26, and includes printed patterns 72a, 72b, and 72.
The brush contact piece 71 is in contact with c. Printed circuit board 72
Has a built-in control circuit. Print pattern 7
2a detects when the second engagement shaft portion 67 is at the light shielding cover open position. The print pattern 72b detects when the second engagement shaft portion 67 is at a position other than the light shielding cover open position. The print pattern 72c is a common pattern.
The rotation position detection signal of the light-shielding lid 49 based on these patterns 72a to 72c is sent to a control circuit (not shown) and used for film winding control.

Further, a regulating engaging portion 73 is formed on the peripheral surface of the second engaging shaft portion 67. The regulating engaging portion 73 includes an engaging convex portion 73a, an engaging concave portion 73b, and a safety lock release. And the safety lock lever 64 is engaged with these.

The safety lock lever 64 is rotatably disposed on the outer case 22 in proximity to the light-shielding cover opening / closing lever 63, and the slide case 12 does not come off the camera body 10 when the light-shielding cover 49 is open. like,
The slide case 12 is locked to restrict its movement. The safety lock lever 64 includes a locking lever portion 75 and an interlocking lever portion 76.
These are integrated so that they do not rotate with each other.

As shown in FIG. 3, the locking lever portion 75 is disposed on the upper surface of the outer case 22 and has a locking claw 75a. The locking claw 75a is locked to the locking projection 17 of the shutter button mounting plate 14 when the interlocking lever portion 76 is at the rotation restricting position, as described later, so that the slide case 12 slides in the opening direction. To block. In addition,
The two-dot chain line LA in the drawing indicates the movement locus of the locking projection 17.

The interlocking lever 76 has an engagement end 76a and is urged clockwise by a coil spring 78. The coil spring 78 is provided with a stopper 79 protruding downwardly from the upper inner surface of the outer case 22 and the interlocking lever 7.
6 and urges the interlocking lever 76 in a counterclockwise direction. Thus, the interlocking lever 76 is held at the rotation restricting position (the position where the locking lever 75 is blocked).

The engaging end 76a engages with the regulating engaging portion 73 of the second engaging shaft 67. If the light-shielding cover 49 is not completely closed, the first and second engagement shaft portions 6 engaged with the light-shielding cover 49 are not closed.
Since neither 6 nor 67 is set at the closed position, as shown in FIG. 11, it stops at the position where the engagement end 76 a hits the engagement projection 73. Therefore, further rotation of the interlocking lever portion 76 is restricted, so that clockwise rotation of the locking lever portion 75 integrated therewith is also restricted. This allows
Since the locking projections 17 of the shutter button mounting plate 14 of the slide case 12 abut against the locking claws 75a of the locking lever portion 75, further sliding movement of the slide case 12 is prevented, and the slide case 12 is safety locked. Stop at the position. Therefore, when the light-shielding lid 49 is not completely closed, the slide case 12 does not come off the camera body 10, so that the bottom lid 43 is not accidentally opened.

When the light shielding cover 49 is completely closed,
Since the first and second engagement shaft portions 66 and 67 are also set to the closed position by the urging of the coil spring 70 shown in FIG. 1, as shown in FIG. The part 76a faces. Therefore, since the clockwise rotation of the safety lock lever 64 is allowed, when the slide case 12 is slid in the opening direction, the locking projection 17 of the shutter button mounting plate 14 causes the locking claw 75a to move during this movement. Rotate to move to the unlock position. Thus, the slide case 12 is not locked at the safety lock position, and the slide case 12 is detached from the camera body 10.

A pushing portion 74 is formed between the engaging concave portion 73a and the engaging convex portion 73b of the regulating engaging portion 73. When the light shielding cover 49 is not completely closed and is stopped in a slightly opened state, the pushing portion 74 forcibly rotates the light shielding cover 49 to the closed position side. Are provided so as to obliquely intersect the insertion path of the engagement end portion 76a. Therefore, as shown in FIG. 13 (A), when the film is completely wound in the film cartridge, and there is no film at the film entrance, and the light shielding cover 49 is not completely closed for some reason. In addition, as shown in FIG. 2B, when the slide case 12 is moved toward the cartridge replacement position in the opening direction, the locking lever 75 is rotated clockwise by the locking projection 17,
By this rotation, the second engagement shaft 67 (see FIG. 1) is rotated counterclockwise via the engagement end 76a of the interlocking lever 76. Thereby, the light-shielding lid can be reliably closed via the first engagement shaft portion 66. When the film is present at the film doorway, as shown in FIG.
Since the engagement end portion 76a is positioned so as to face the engagement projection 73a, the interlocking lever portion 76 of the safety lock lever 64 is prevented from rotating, so that the above-described forced closing operation is performed. There is no.

In the present embodiment, as shown in FIG. 13B, the turning angle θ1 of the light shielding cover is set to about 90 degrees, and the closed position area θ2 is set to about 4 degrees. .
In addition, the forcibly closed region θ3 by the pushing portion 74 is set to about 10 degrees.

When repairing a failure or the like, it may be necessary to release the safety lock and forcibly remove the slide case. At this time, as shown in FIG. 14, the drive lever 65 is rotated by a finger or the like so as to enter the safety lock release area θ4. In this state, the engagement projection 73a of the regulating engagement portion 73 is disengaged from the engagement end 76a of the interlocking lever portion 76, and the safety lock release engagement recess 7 is released.
3c, the interlocking lever 76 can be rotated clockwise. Therefore, since the rotation of the locking lever portion 75 in the unlocking direction is allowed, the slide case 12
Can be moved in the opening direction, and the slide case 12 can be removed from the camera body 10.

A photographing position lock device for stopping the slide case 12 at the photographing position is provided. This photographing position lock device includes a first lock mechanism 81 shown in FIG. 15 and a second lock mechanism 82 shown in FIG. 16 to reliably stop the slide case 12 at the photographing position.

As shown in FIG. 15, the first lock mechanism 81
When the slide case 12 is slid in the opening direction, the slide case 12 is stopped at the photographing position. The first lock formed on the photographing position locking lever 83, the lock release plate 85, and the shutter button mounting plate 14 It is composed of an edge 15.

The photographing position locking lever 83 moves the slide case 1 toward the cartridge replacement position (case opening direction (arrow B direction)) of the slide case 12 in the photographing position.
The first locking claw 8 is provided at one end.
3a is provided with an engaging portion 83b at the other end. The photographing position locking lever 83 is rotatably attached to a partition plate 50a (see FIG. 7) constituting the battery chamber storage case 50 of the camera body 10 via an attachment shaft 86. Then, the first locking claw 83a shifts between a locking position where it protrudes from the camera body 10 through the slit 22b and a locking release position where the first locking claw 83a sinks into the camera body 10. The locking lever 83 is provided with a coil spring 87, and the coil spring 87 biases the locking lever 83 toward the locking position.

In the locking position, the first locking claw 83a protrudes from the slit 22b of the camera body 10, so that when the slide case 12 is slid in the opening direction, it is disposed on the upper inner surface of the slide case 12. The first locking edge 15 of the shutter button mounting plate 14 is locked to the first locking claw 83a, and further movement of the slide case 12 is prevented, and the slide case 12 is stopped at the photographing position.

The lock release plate 85 is disposed inside the corner of the battery lid 52 bent in an L-shape to achieve compactness. The lock release plate 85 is slidably mounted in the slide direction of the slide case 12 and is slidable between an unlocked position that projects laterally from the battery lid 52 and a storage position that does not project. Has been. The lock release plate 85 is provided with an operation protrusion 85a through the slide opening 52b of the battery cover 52. The operation protrusion 85a is arranged in a slide opening 52b formed at a corner of the battery cover 52 so as not to protrude from the surface of the battery cover 52 to the outside.

When the unlocking plate 85 is slid in the unlocking direction, the locking lever 8 is moved through the tapered surface 85a.
3 is moved from the locked position to the unlocked position. Lock lever 8
When the lock 3 is in the unlocked position, the slide case 12 can slide in the opening direction, and as shown in FIG.
The slide case 12 can be set at the cartridge replacement position removed from the camera body 10.

As shown in FIG. 16, the second lock mechanism 82
When the slide case 12 slides in the closing direction (the direction of arrow C), the slide case 12 is stopped at the photographing position, and is formed on the photographing position locking plate 90, the interlocking arm 91, and the shutter button mounting plate 14. The second locking edge 16 is formed.

The photographing position locking plate 90 is formed of a spring plate and has a second locking claw 90a. This photographing position locking plate 90 is attached via an attachment portion 90b provided at one end.
It is arranged at the upper front side of the outer case 22 and inside. The second locking claw 90a protrudes from the slit 22c of the outer case 22.

At the other end of the photographing position locking plate 90, an engaging piece 90c is formed by bending. This engagement piece 90c
, The interlocking arm 91 is engaged. The interlocking arm 91 is
The flash unit 5 is fixed to the end of the mounting shaft 56 of the flash unit 5, and when the flash unit 5 is in the storage position, the engaging piece 90c is pushed down as shown in FIG. Therefore, the second locking claw 90a enters the unlocked state in which it is immersed in the slit 22c. Also, as shown in FIG. 16, when the strobe light emitting unit 5 pops up, the interlocking arm 91 rotates upward to release the downward pushing of the engaging piece 90c. Therefore, the photographing position locking plate 90 returns to the original locking position by its own elasticity, and the second locking claw 9
0a is projected from the slit 22c.

When the second locking claw 90a is in the locking position,
The second of the shutter button mounting plate 14 of the slide case 12
It locks to the locking edge 16. Therefore, when the slide case 12 slides in the closing direction (the direction of arrow C),
The second locking claw 90a is locked to the second locking edge 16 to prevent the slide case 12 from moving in the closing direction. This prevents the end face of the slide case 12 from hitting the side face of the slide light emitting unit 5 that has popped up.

When the slide case 12 is to be further slid in the closing direction, the strobe light emitting section 5 is pushed downward and set to the storage position as shown in FIG. Due to the shift to the storage position, the interlocking arm 91 pushes down the photographing position locking plate 90 via the engaging piece 90c, and the second locking claw 90a is set to the unlocking position. Thereby, the restriction on the movement of the slide case 12 in the closing direction is released, and the slide case 12 can be moved in the closing direction. In this unlocked state, the strobe light emitting unit 5 is set at the storage position. Further, since the power switch 58 is turned off, the movable barrel 4 is stored in the fixed barrel 29. Accordingly, the slide case 12 is slid to the unused position as shown in FIG.

As shown in FIG. 15, the first and second locking claws 83a and 90a are formed on the inclined surface opposite to the locking direction, and allow the slide case 12 to move in this direction. It has become.

As shown in FIG. 17, the slide case 12
A non-use position locking mechanism 93 is provided in order to prevent the opening at the non-use position. The non-use position locking mechanism 93 includes a second locking projection 18 of the shutter button mounting plate 14 and a safety lock lever 64, and the second locking projection 18 is provided on a locking claw 75 a of the safety lock lever 64. Is click-locked.

When the slide case 12 is in the photographing position and the non-use position, the slide case 12 sets the engaging shaft 66 of the light-shielding lid opening / closing lever 63 to the light-shielding lid closed position. Therefore, the safety lock lever 64
The engaging end 76a does not face the engaging projection 73a of the restricting engaging portion 73, and the clockwise rotation (lock release position) of the safety lock lever 64 is allowed. Thereby, the locking claw 75 of the safety lock lever 64
As a result, the locking projection 18 of the shutter button mounting plate 14 can be click-locked at the unused position. As described above, by using the locking lever portion 75 of the safety lock lever 64, the slide case 12 can be click-locked at the unused position without newly providing a locking lever or the like.

Next, the operation of the above embodiment will be described. When the camera 2 is not used, as shown in FIG. 4, the slide case 12 is set at an unused position covering the photographing lens 3, the strobe light emitting unit 5, and the liquid crystal display 13. In this state, the slide case 12 is
Since the camera 2 covers almost two-thirds of 0, the camera 2 is almost the same size as the camera body 10, and the portability is improved. Further, since the slide case 12 covers the photographing lens and the strobe light emitting portion of the camera body 10, dust and the like are prevented from entering between the camera body 10 and the slide case 12.

As shown in FIG. 17, when the slide case 12 is in the non-use position, the shutter button 1
1 is an operation button 4 of a micro switch of the camera body 10
Since the shutter button 11 is located at a position distant from 2a, photographing is not performed even if the shutter button 11 is erroneously pressed. Further, since the power switch 58 (see FIG. 10) is turned on in conjunction with the pop-up of the strobe light emitting unit 5, when the slide case 12 is in the non-use position, the power of the camera 2 is turned off. It is kept as it is.

The camera 2 has a film cartridge 39
Is loaded, the slide case 12 is moved in the opening direction. Due to the movement in the opening direction, the slide case 12 is first stopped at the photographing position shown in FIG. 2 by the photographing position lock device. At this photographing position, since the slide case 12 does not press the strobe light-emitting unit 5, the strobe light-emitting unit 5 pops up due to the bias of the spring. The power switch 58 is turned on in conjunction with the pop-up of the strobe light emitting unit 5.

Further, in order to slide the slide case 12 in the opening direction, as shown in FIG. 13, the operation projection 85a of the battery cover 52 is operated to release the locking of the photographing position lock device. Thereby, the locking between the first locking claw 83a and the first locking edge 15 on the slide case 12 side is released, and the slide case 12 can be moved in the opening direction. When the end of the slide case 12 passes through the light shielding cover opening / closing lever 63 due to the movement in the opening direction, the light shielding cover opening / closing lever 63 is closed by the bias of the coil spring 69 as shown in FIG. To rotate. In a state where the cartridge is not loaded, as shown in FIG. 12, the engagement end portion 76a of the safety lock lever 64 enters the engagement concave portion 73b of the light shielding cover opening / closing lever 63, so that the rotation of the safety lock lever 64 does not rotate. Permissible. For this reason, the locking projection 17 is not locked by the locking claw 75 a of the safety lock lever 64 during the movement of the slide case 12. Therefore, the slide case 12 is not safety-locked, and the slide case 12 is at the cartridge replacement position where the slide case 12 is detached from the camera body 10.

When the slide case 12 is detached from the camera body 10 and set at the cartridge replacement position, the restriction on the opening of the bottom cover 43 by the slide case 12 is released.
As shown in FIG. 9, the bottom cover 43 can be opened. When the bottom cover 43 is opened and the film cartridge 39 is loaded into the cartridge chamber 26, the support shaft 60 is inserted into the engagement hole 41a of the spool 41 of the film cartridge 39 as shown in FIG. The engagement end 66a of the light shielding cover opening / closing lever 63 engages with 49a. When the bottom cover 43 is closed, the drive shaft 44 of the bottom cover 43 is engaged with the engagement hole 41a of the spool 41.

After the bottom cover 43 is closed and the slide case 12 is set on the camera body 10, as shown in FIG.
When the slide case 12 is slid to the photographing position, the edge of the slide case 12 hits the drive lever 65 of the light-shielding cover opening / closing lever 63 in the middle, and the drive lever 65
Is rotated approximately 90 degrees clockwise. As a result, the light shielding cover 49 is set from the closed position to the open position via the first and second engagement shaft portions 66 and 67. Then, the second locking edge 16 on the slide case side is locked to the second locking claw 90a, so that the slide case 12 is stopped at the photographing position. When the slide case 12 is set on the camera body 10, the bottom cover 43 is at least partially covered by the slide case 12, so that the bottom cover 43 cannot be opened.

When the light blocking cover opening / closing lever 63 is switched from the closed position to the open position by moving the slide case 12 in the closing direction, the brush contact piece 71 and the print pattern 72 are switched.
The open position of the light-shielding lid 49 is detected via a to 72c.
Also, since the power switch has already been turned on in conjunction with the pop-up of the strobe light emitting unit 5, an AND signal between the open position detection signal and the cartridge detection signal of the cartridge sensor or the spool position detection signal of the spool sensor is output. Then, the leading end of the film is fed.

That is, when the power of the camera body 10 is turned on, the control circuit detects the presence of the film cartridge 39 in the cartridge chamber 26 by the cartridge sensor. Further, the rotational position of the spool 41 is detected by the spool sensor, and it is determined from the rotational position whether the loaded film cartridge 39 is unused.

The presence of the film cartridge 39 is detected, and if the film cartridge 39 is not yet used, the motor 37 and the gear train 4 are used as shown in FIG.
7. The spool 41 is rotated in the film sending direction via the connecting gear 46, the driving gear 45, and the driving shaft 44, and the photographic film 40 is sent out from the film entrance. The control circuit reads the bar code on the bar code plate 41b by the bar code sensor at the time of feeding the film.
The contents of the barcode are the sensitivity of the photo film 40, the number of shots, and the like. This data is stored in a memory in the control circuit and used for various controls during shooting.

The photographic film 40 sent out from the film entrance passes behind the aperture 25 and reaches the film winding chamber 27, and the leading end is wound around the winding shaft 36. The take-up shaft 36 takes up the photographic film 40 at a speed higher than the feeding speed of the photographic film 40.
Then, the gear train 47 cuts off the drive to the spool 41,
Thereafter, the photographic film 40 is wound up only by the rotation of the winding shaft 36. The perforation of the photographic film is detected by a perforation sensor (not shown), and the first frame of the photographic film 40 is set behind the aperture 25 based on this detection signal.

At the time of photographing, the slide case 12 is used as a grip, and the composition is confirmed by looking into the eyepiece side of the viewfinder 6. Thereby, it is possible to prevent the photographing lens 3 and the strobe light emitting unit 5 from being fingered. FIG.
As shown in (2), when the slide case 12 is at the shooting position, the shutter button 11 is disposed above the operation button 42a of the micro switch 42, so that the shutter button 11 can be pressed. When the shutter button 11 is lightly pressed, the micro switch 42 is turned on at the first stage.

When an ON signal is input at the first stage of the microswitch 42, the control circuit operates the distance measuring light projecting window 8 and the distance measuring light receiving window 9 to measure the distance to the object. ,
The photographing lens 3 is focused. At the same time, the brightness of the subject is measured through the photometric window 7. If the brightness of the subject is low, or if the strobe forced light emission mode is selected by operating the panel switch 21, the power of the strobe light emitting unit 5 is turned on, and charging of the main capacitor is started.

When the shutter button 11 is depressed deeply, the micro switch 42 is turned on at the second stage. The control circuit is
When an ON signal at the second stage of the microswitch 42 is input, the shutter device disposed behind the photographing lens 3 performs shutter release, and at the same time, causes the strobe light emitting unit 5 to emit strobe light toward the subject. . When the shutter release is completed, the control circuit rotates the take-up shaft 36 to transfer one frame of the photographic film 40 to the film take-up chamber 2.
Roll up to 7.

After the photographing is completed, the slide case 12
Slide from the shooting position to the unused position. In this case, as shown in FIG. 15, the strobe light-emitting unit 5 that is popping up is pressed from above to bring it into the storage position. As a result, the second locking claw 90a of the photographing position lock device is retracted into the outer case 22 by the interlocking arm 91 attached to the strobe light emitting unit 5, and the lock to the photographing position is released, and the non-use position side The slide case 12 is allowed to move. When the interlocking arm 91 is lowered, the power switch 58 is turned off, and the movable barrel 4 is collapsed in the fixed barrel 29. When the slide case 12 is slid in the closing direction in this state, the second locking projection 1 of the shutter button mounting plate 14 is moved.
8 pushes the locking claw 75a of the safety lock lever 64 and stops at a position where the locking claw 75a has passed over the locking claw 75a. As a result, the slide case 12 is click-locked at the unused position, and the slide case does not accidentally move to the photographing position side at the unused position.

When the capacity of the battery 19 decreases, an indication to that effect is displayed on the liquid crystal display 20. In this case, as shown in FIG. 15, the operating projection 85a of the battery cover 52 is operated to release the lock of the first locking claw 83a with the first locking edge 15, and the slide case 12 is moved. Slide in the opening direction from the shooting position. When the film is wound around the winding shaft 36, the light shielding cover 49 is not closed because the film is in the film passage where the light shielding cover 49 is located. Thereby, as shown in FIG. 11, the safety lock lever 64 is prevented from rotating at the safety lock position. Therefore, slide case 1
Since the locking projection 17 on the second side is locked to the locking claw 75a of the safety lock lever 64, the slide case 12 stops at the safety lock position.

In this safety lock position, as shown in FIG. 5, the battery cover 52 is no longer covered by the slide case 12, and the battery cover 52 can be opened upward. Thereafter, the consumed battery 19 is removed from the battery storage case 50, a new battery 19 is set in the battery storage case 50,
The battery cover 52 is closed. Next, if the slide case 12 is slid to the shooting position again, shooting can be continuously performed. The battery may be replaced by stopping the battery cover 52 at a position where the battery cover 52 is completely exposed from the slide case 12 without pulling out the slide case 12 to the safety lock position.

When the photographing of all the frames of the photo film 40 is completed, the control circuit drives the drive transmission mechanism to rewind the photo film 40 into the film cartridge 39.
Further, during the rewinding, the rotation position of the spool 41 is detected by the spool sensor, and the film cartridge 39 is detected.
The spool 41 is positioned so as to indicate that shooting has been completed. After the rewinding of the photo film 40 is completed, the slide case 12 is slid to the cartridge replacement position.

When the photographic film 40 is completely wound into the film cartridge 39 and the slide case 12 is slid toward the cartridge replacement position, the light-shielding cover opening / closing lever 63 moves from the open position to the closed position as the slide case 12 moves. Urged by a coil spring 69. Therefore, the light shielding cover 49 is also set to the closed position by rotating the light shielding cover opening / closing lever 63 to the closed position. When the light-shielding cover opening / closing lever 63 is set to the closed position, as shown in FIG. 12, the engaging concave portion 73b allowing the rotation of the safety lock lever 64 is located at the position facing the engaging end portion 76a. 64 is allowed to rotate in the unlocking direction. Thereby, the safety case is not locked, and the slide case 12 is set at the cartridge replacement position removed from the camera body 10.

When the slide case 12 is slid toward the cartridge replacement position while the photographic film 40 is being wound on the take-up shaft 36, as shown in FIG. Part 76a
Are not located in the engagement concave portions 73b, and the engagement convex portions 73a
, The rotation of the safety lock lever 64 in the unlocking direction is restricted. Therefore, the slide case 12 cannot slide from the safety lock position to the opening direction. Therefore, since it is impossible to open the bottom cover 43, the exposure of the photographic film due to the accidental opening of the bottom cover 43 is prevented.

Further, the photographic film is completely wound up in the cartridge. If the light-shielding cover 49 is not completely closed for some reason even though there is no film in the film passage where the light-shielding cover 49 is located, As shown in FIG. 13, the pushing portion 74 of the light-shielding cover opening / closing lever 63 is located at a position facing the engaging end 76 a of the safety lock lever 64. Therefore, when the slide case 12 is moved in the opening direction, the safety lock lever 64 rotates clockwise via the locking projection 17, and as shown in FIG.
Since the pushing portion 74 is pushed by the engagement end portion 76a, the light shielding cover opening / closing lever 63 is forcibly rotated counterclockwise, and the light shielding cover 49 is forcibly set to the closed position.

When it is necessary to release the safety lock due to a failure repair or the like, as shown in FIG.
4 to allow the safety lock lever 64 to rotate clockwise. Thus, the locking projection 17 is not locked by the locking lever portion 75 of the safety lock lever 64, and the slide case 12 can be removed from the camera body 10.

In the above-described embodiment, the regulating engagement portion 73 is constituted by the engagement projection 73a, the engagement recess 73b, and the safety lock release engagement recess 73c. However, in some cases, the safety lock release engagement recess 73c is provided. May be omitted.
In addition, although the pushing portion 74 is provided between the engaging convex portion 73a and the engaging concave portion 73b, this may be omitted.

In the above-described embodiment, the photographing position lock device is constituted by the first and second lock mechanisms 81 and 82 provided separately. However, these lock devices may be constituted by one lock mechanism. .

In the above embodiment, when the slide case 12 is slid to the unused position, the camera body 10
The liquid crystal display 13 on the back side of the liquid crystal display 13 is concealed. Alternatively, the liquid crystal display 13 may be provided at a position not covered by the slide case 12. In this case, the remaining number of photo films, the type of film, and the like are displayed on the liquid crystal display even at the non-use position, so that these can be confirmed without setting the photograph position.

In the above-described embodiment, the power switch 58 is provided so as to interlock with the pop-up of the strobe light emitting unit 5. However, a power switch may be provided so that the slide case 12 is turned on when the slide case 12 is in the photographing position. In the above embodiment, a micro switch is used as the power switch 58 as shown in FIG.
The power switch 58 is provided by a switch piece contacted by
, And in this case, the size and cost can be further reduced.

According to the present invention, the light-shielding lid opening / closing means is provided, and the light-shielding lid opening / closing means engages with the slide case when the slide case moves in the closing direction from the cartridge exchange position to the photographing position, thereby shielding the film cartridge from light. Since the lid is moved from the closed position to the open position, when the film is loaded and the slide case is slid on the camera body, the light shielding lid can be automatically set from the closed position to the open position. Further, since the light shielding cover opening / closing means is urged to the closed position by the first urging means, when the slide case is slid to the cartridge replacement position, the light shielding lid opening / closing means can automatically close the light shielding lid. In addition, since the film is not completely wound into the film cartridge and there is a film in the film passage having the light-shielding lid, the light-shielding lid is forcibly moved to the closed position because the bias is set to the closed position by the bias. There is no damage to the light-shielding lid and the light-shielding lid opening / closing means.

The light blocking cover opening / closing means has a double structure with an engagement shaft portion and a drive lever portion, and these are linked by the second urging means and the transmission engagement portion. In the disengaged state, the drive lever is always closed by the second biasing means irrespective of the position of the light shielding cover, so that the drive lever is not erroneously operated.

When the slide case is moved from the photographing position to the cartridge replacement position in the opening direction, the safety lock means engages with the light blocking cover opening / closing means to regulate the movement of the slide case in the opening direction when the light blocking cover is opened. Since the movement of the slide case in the opening direction is restricted when the light shielding cover is open, the slide case does not come off from the camera body. This prevents the light-shielding cover of the cartridge chamber such as the bottom cover from being opened by mistake and prevents the film from being exposed to light.

The safety lock means includes a first locking portion formed on the slide case, a safety lock lever,
The safety lock lever restricts the movement of the safety lock lever to the blocking release position when the light-shielding lid is open. Can be reliably restricted from moving in the opening direction. Therefore, the movement of the slide case in the opening direction is restricted, so that the cartridge cannot be replaced, and the film cartridge is not taken out with the light-shielding cover opened.

The restricting engagement portion is provided with an engagement concave portion which allows the interlocking lever to rotate when the light shielding cover is at the closed position, and a rotation of the interlocking lever portion when the light shielding cover is at a position other than the closed position. , The safety lock can be reliably performed. Further, by providing a pushing portion for rotating the light-shielding lid toward the closed position via the light-shielding lid opening / closing means by rotating the interlocking lever when the light-shielding lid is near the closed position, the light-shielding lid is positioned near the closed position. If it is not completely closed, it can be reliably closed. In addition, by providing a safety lock release engagement concave portion that allows the interlocking lever portion to rotate when the light blocking cover is near the open position including the open position, the safety lock is released in the case of a failure repair, etc. Can be removed from the camera body.
