Abstract

PURPOSE:To switch normal and panoramic photographing through a simple operation by providing a tripodal screw member which can rotate with respect to a main body, and a mechanism which selectively transmits the normal/reverse rotary outputs of motor for taking up and rewinding a film to a rewinding spool or the tripodal screw member, etc. CONSTITUTION:When a locking member 20 and a control lever 12 are moved outside locking positions, that is, out of a moving space through the operation of an operation mans 22, a rocking gear 7 is moved to a first position by the normal rotation of the motor M, and the normal rotary output is transmitted to a spool 1. When the rocking gear 7 is moved to a second position by the reverse rotation, the reverse rotary output is transmitted to the rewinding spool 11. On the other hand, when the locking member 20 and the control lever 12 are moved in non-locking positions, that is, in the moving space through the operation of the operation means 22, the same action is carried out with respect to the normal rotation of the motor 7. However, in the case of reverse rotation of the motor 7, the movement of the gear 7 to the second position is blocked by the control lever 12, so that the reverse rotary output is transmitted to the tripodal screw member 16. Thus, normal photographing or panoramic photographing is properly selected through simple switching operation.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a panoramic camera that can select between so-called panoramic photography, which continuously photographs a wide range of subjects, and normal photography, as appropriate, by a simple switching operation. It is something.

2. Description of the Related Art Various methods and cameras have been proposed or put into practical use for so-called panoramic photography, in which a wide range of subjects are continuously photographed.

For example, - You can shoot one frame at a time by attaching an ultra-wide-angle lens to an eye reflex camera or large view camera, or - You can shoot one frame at a time using an eye reflex camera or compact camera and adjust the field of view of each camera. After continuous shooting,
A method for obtaining a panoramic photograph by pasting together a desired number of completed photographs is well known.

Another well-known method is to arrange a slit in front of the film inside the camera body, synchronize the camera body with the film transport speed, and rotate it in the opposite direction to the film transport direction to take continuous photographs and obtain panoramic photographs. It is.

However, most of the cameras that use the well-known method described above are so-called panoramic-only cameras that can only perform panoramic operations, and cannot perform normal photography.

On the other hand, as a camera that takes the above-mentioned points into consideration, a panoramic photography camera disclosed in Japanese Patent Application Laid-Open No. 52-29729 has been proposed.

The panoramic photography camera disclosed in the above publication is
It consists of a stopper fixed to the winding drum, a stopper that can make both contact and release from the stopper, and a small gear for rotating the film winding spool shaft, which is installed in a normal snapshot camera. , the lower surface of the camera body is inserted into the motor shaft protruding from the upper surface of the large gear of the motor attached to the lower surface of the large gear that is fixedly supported on the stand that meshes with the small gear, and the camera body is connected via the clutch mechanism. The rotational movement of the camera and the rotation of the film winding Lisbourg are linked to take panoramic photographs.

That is, it is constructed by modifying a normal snapshot camera by adding a small gear or the like, and then attaching a motor, a large gear, or the like as an adapter to the modified camera.

Problems to be Solved by the Invention As mentioned above, most of the conventionally known panoramic cameras are dedicated to panoramic photography, so if you want to do general photography, you need to prepare a separate camera. ,
This has the disadvantage of increasing the expense burden on the photographer.

On the other hand, the panoramic photography camera disclosed in the above-mentioned proposal can take both panoramic photography and general photography, so the above-mentioned disadvantages can be overcome, but the motor, which is the drive source for panoramic photography, Since it is constructed in the form of an adapter, the installation or switching work is complicated and there is a disadvantage in that it lacks maneuverability.

Furthermore, because it was an adapter format, the overall size and cost of the device inevitably increased compared to general photography cameras.

The present invention was developed in consideration of the above-mentioned points, and uses the motor that is built into the camera body and serves as the drive source for automatically winding and rewinding the film as the drive source for panoramic photography. To provide a panoramic camera capable of appropriately selecting and performing general photography and panoramic photography with only extremely simple switching operations without using an adapter format.

Means for Solving the Problems A panoramic camera according to the present invention has a motor that serves as a drive source built into the camera body, and is capable of swinging between first and second positions by transmitting forward and reverse outputs of the motor. a first swinging mechanism comprising at least one swinging gear;
A first transmission gear train that meshes with the swing gear in the first position and transmits the forward rotation output of the motor to the subroutine to wind the film, and meshes with the swing gear in the second position. , a second transmission gear train that transmits the reversing output of the motor to the rewinding shaft to rewind the film; and a tripod screw hole in the center of the main body, and a gear part that covers part of the entire circumference of the side of the main body, and a gear part that extends all the way around the other part. A plurality of locking recesses are provided around the circumference, and the bearing is fitted with a tripod screw member attached to the camera body via a mechanism so as to be rotatable relative to the camera body, and a locking position that fits into the recess. a locking member that is moved between non-locking positions where the rocking gear does not fit, and a locking member that moves the rocking gear into the movement space from the first position to the second position, thereby moving the rocking gear to the first position; a control lever that prevents movement from the oscillating gear to the second position and controls the swing gear to a third position between the first and second positions; a second rocking mechanism comprising a control gear that meshes with the rocking gear that is in the third position when the camera moves to the third position; and an intermediate gear that meshes with the control gear; and the locking member that is operated from outside the camera. and the control lever are moved in conjunction with each other to the locking position and the control lever, respectively.
An operating means positioned outside the moving space, at the unlocked position, and inside the moving space, and a reverse rotation output of the motor supplied via the second swing mechanism to the gear portion of the tripod screw member. a third transmission gear train for transmitting data, and the locking member and the control lever are positioned in the non-locking position and inside the movement space based on the operation of the operating means;
and unwinding prevention means for supplying a certain amount of load to the rotation of the spool when the rocking gear moves from the first position, and control of the tripod screw member by the locking member based on the operation of the operating means. and a motor drive circuit that detects the operating state of the camera and controls the forward and reverse operating states of the motor.

Operation Since the panoramic camera according to the present invention is configured as described above, when the locking member and the control lever are respectively moved to the locking position and outside the movement space based on the operation of the operating means,
The normal rotation of the motor moves the swing gear to the first position, so that the normal rotation output is transmitted to the spool via the swing gear and the first transmission gear train, and the reverse rotation moves the swing gear to the second position.
position, so that its reversal output is transmitted to the rewinding shaft via the rocking gear and the second transmission gear train.

That is, in the above case, by controlling the forward and reverse movements of the motor based on the normal photographing operation, the well-known film winding and rewinding operations can be performed, in other words, the conventionally well-known general photographing can be performed. become.

On the other hand, when the locking member and the control lever are respectively moved to the non-locking position and inside the movement space based on the operation of the operating means, the swing gear moves to the first position due to normal rotation of the motor, and in the above case The same operation as above is performed, but the control lever prevents the swing gear from moving to the second position due to the reversal of the motor, and the swing gear is placed in the third position, and its reverse rotation output is controlled. It will be transmitted to the tripod screw member via the gear and the third transmission gear train.

At this time, if the tripod screw hole of the tripod screw member is engaged with the tripod screw, the camera body will rotate around the tripod screw member.

Therefore, by alternately repeating the shutter operation and the forward and reverse operations of the motor, panoramic photography can be performed frame by frame.

At this time, even though the film is an intermediate frame, the swing gear moves from the first position, that is, the spool is separated from the drive system, but the film is rewound due to the elasticity of the film due to the rewind prevention means. Never.

Embodiments Below, embodiments of the panoramic camera of the present invention will be described.

FIG. 1 is a schematic plan view for explaining the general configuration of a panoramic camera according to the present invention.

A motor M shown by a broken line is built into the spool 1, and its rotational output is taken out via a pinion gear 2.

In addition, the spool 1 is provided with a rewinding prevention function to prevent the film F from being rewound due to the elasticity of the film F when a repanoramic shooting mode is set by an operating means 22 to be described later and the swing gear 7 to be described later is separated from the spool 1. It is equipped with means 1b.

The rewinding prevention means 1b may be, for example, a well-known friction spring or a ratchet pawl that acts only in the panoramic shooting mode to prevent the spool 1 from rotating in the rewinding direction and only allows rotation in the winding direction. It is conceivable to use a ratchet mechanism or the like that applies a load to the rotation of the spool 1 in the unwinding direction so that the film F does not unwind in the above-mentioned case.

The pinion gear 2 is connected to a main gear 5, which forms a first swing mechanism 4 together with a swing lever 6 and a swing gear 7, which will be described later, via an appropriate transmission gear train 3 consisting of a plurality of gears.

A swing lever 6 is frictionally connected to the rotation center 5a of the main gear 5, and a swing gear 7 that meshes with the main gear 5 is rotatably provided on the swing lever 6.

Based on the rotation of the main gear 5 by the forward and reverse rotation of the motor M, the swing gear 7 is moved between a first position shown by a dashed line in the figure, where it meshes with the gear portion 1a of the spool 1, and a second position where it meshes with a gear 9, which will be described later. 2
Can be moved between locations.

In the figure, the swing gear 7 and the gear part 1a are directly meshed, but an appropriate gear may be interposed between them, and the gear part 1a or the above-mentioned appropriate gear can be used as the first transmission. Needless to say, this corresponds to a gear train.

Further, a pin 8 is installed at the center of rotation, and this pin 8
is in contact with a control lever 12, which will be described later, to restrict movement of the swing gear 7 in the counterclockwise direction, that is, movement to the second position.

The gear 9 is connected to the gear section 11. of the unwinding shaft 11 via a second transmission gear train 10 consisting of a plurality of gears. It is connected to a.

The control lever 12 has an abbreviated shape, is frictionally coupled to the center of rotation of the intermediate gear 13, and includes a control gear 14 that meshes with the intermediate gear 13.

That is, the control lever 12, the intermediate gear 13, and the control gear 14 form a second swing mechanism 15, and the control lever 12 moves into the swing gear indicated by a solid line based on the operation of the operating means 22, which will be described later. The robot is moved between three positions: a position inside the movement space 7 and a position outside the movement space indicated by a two-dot chain line.

The intermediate gear 13 has a tripod screw hole 17 in the center of the main body, a gear part 18 covering a part of the entire circumference of the side surface of the main body, and a plurality of locking recesses 19 covering the other part of the entire circumference, and is attached to the camera main body B. A bearing, which is not shown in the drawings, is rotatably engaged with the gear portion 18 of the tripod screw member 16 attached to the main body B via a mechanism.

That is, in the illustrated configuration, the third transmission gear train described above is also used as the intermediate gear 13, and the configuration is simplified, but if necessary, an appropriate gear train can be used as an independent third transmission gear train. It goes without saying that it may be provided.

A locking member 20 having a cross-shaped shape similar to the control lever 12
is provided so as to be rotatable about a rotation center 20a, and its tip 20b is configured to be able to engage with the locking recess 19.

The spring 21 connects the control lever 12 and the locking member 20 described above.
They are constantly energized counterclockwise and clockwise, respectively.

In the figure, the operating means 22 is located on the back of the camera body B.
is approximately H which integrally includes an operation knob 23, a control bin 24, 25, and a sliding groove 26 led out from the back surface of the main body B.
It is composed of a switching lever 27 having a shape.

The sliding range of the switching lever 27 is regulated by the relationship between the sliding groove 26 and the fixed bin 28.29 provided on the camera body B, and the control bin 24.2 during the sliding operation.
5 to control the movement of the control lever 12 and the locking member 20 to switch between the general photography mode and the panoramic photography mode.

Next, the operation of the panoramic camera according to the present invention will be described with reference to the schematic diagram shown in FIG. 1 mentioned above.

First, the case of the general photography mode in which normal photography is performed will be explained.

In this case, the switching lever 27 of the operating means 22 is slid from the illustrated position to the left by a range determined by the sliding groove 26 and the fixing pins 28 and 29.

Then, the control bins 24 and 25 also slide to the left, controlling the operation of the control lever 12 and the locking member 20, respectively, together with the spring 21, so that both of them move to the positions indicated by the two-dot chain lines in the figure. Become.

In the above state, when the motor M rotates forward and the counterclockwise normal rotation output shown by the solid line in the figure is taken out by the pinion gear 2, each gear of the transmission gear train 3 will be rotated as shown by the solid line. The normal rotation output is transmitted to the first swing mechanism 4, and the main gear 5 rotates in the clockwise direction shown by the solid line.

Therefore, the swing lever 6 and the swing gear 7 also move clockwise, and the state shown by the dashed line in the figure, that is, the state where the swing gear 7 is located at the first position where it meshes with the spool 1. is obtained.

The swing gear 7 also meshes with the main gear 5, and in the above case,
The counterclockwise rotation causes the spool 1 to rotate clockwise, so that the spool 1 winds up the film F.

Therefore, although not described in detail, by controlling the normal rotation operation of the motor M using a conventionally well-known motor drive system, that is, a motor drive system that partially winds up the shutter after the shutter operation,
This allows you to perform film winding operations during general photography.

Note that when the rotation of the motor M stops, the spool 1 is separated from the drive source, but the spool 1 is in mesh with a plurality of gears via the swing gear 7, and the elasticity of the film F causes the spool 1 to be disconnected from the drive source. It is needless to say in detail that rotation is substantially prevented and cannot easily occur, and therefore, in such a case, there is no need for the unwinding prevention means 1b to operate in particular.

On the other hand, when motor M is reversed, contrary to the previous case, the reverse rotation output in the clockwise direction indicated by the broken line in the figure is transmitted to pinion gear 2.
The transmission gear train 3 and the main gear 5 rotate in the directions indicated by broken lines.

When the main gear 5 rotates in the direction shown by the broken line, the swing lever 6 and the swing gear 7 also rotate in the same direction, and the above-mentioned meshing state of the swing gear 7 with the spool 1 is released. In such a case, the control lever 12 moves the swing gear 7 based on the operation of the operating means 22, as described above.
Since it is moved to the outside of the movement space of , it is moved to the second position where it meshes with the gear 9.

Therefore, the gear 9 rotates in the counterclockwise direction shown by the broken line in the figure, rotates each gear of the second transmission gear train 10 in the direction shown by the broken line, and transfers the reverse rotation output of the motor M to the rewinding shaft 11.
to communicate.

The rewinding shaft 11 rotates in the counterclockwise direction shown by the broken line by the transmission of the reversing output, thereby allowing the film F to be rewound.As a result, for example, the use of the last frame of the film F is detected and the rewinding is automatically performed. By controlling the operation of the motor M in reverse using a well-known motor drive system that performs the rewinding operation, the rewinding operation in general photography can be performed.

It is conceivable that when the engagement between the swing gear 7 and the gear portion 1a of the spool 1 is released, the spool 1 is completely separated from the drive system and rotates in the rewinding direction due to the elasticity of the film F. However, in such a case, the film F is being rewound, and even if the rewound occurs, there is no particular problem; therefore, in this case as well, the rewind prevention means 1b
It goes without saying that there is no particular need for this to work.

As described above, in the panoramic camera according to the present invention, when the switching lever 27 of the operating means 22 is slid to the left, the forward and reverse operations of the motor M are controlled based on the shutter operation, etc. This allows it to operate as a conventionally well-known electric camera with electric winding and rewinding functions.

Next, the case of performing panoramic photography will be described.

In this case, contrary to the previous case, the switching lever 27 of the operating means 22 is slid to the illustrated state.

Then, the contact between the control bin 24 and the control lever 12 is released, and the control bin 25 and the locking member 20 are brought into contact with each other, so that the control lever 12 and the locking member 20 are in the state shown by solid lines in the figure. becomes.

That is, the control lever 12 moves into the movement space of the swing gear 7 to the second position and becomes in a state where it can come into contact with the pin 8,
The locking member 20 is in a state in which the distal end portion 20b and the locking recess 19 are disengaged.

In the above state, when the motor M now rotates in the normal direction, the normal rotation output is taken out via the pinion gear 2 as an output in the counterclockwise direction shown by the solid line in the figure, as in the previous case, and is sent to the transmission gear train 3. The signal is then transmitted to the main gear 5.

Therefore, the swing lever 6, the swing gear 7, etc. operate as described above, and the film F can be wound by controlling the operation of the motor M using an appropriate motor drive system.

That is, the operation when the motor M rotates in the normal direction is no different in the case of panoramic photography than in the case of general photography described above.

Next, when the motor M reverses, the clockwise reverse rotation output shown by the broken line in the figure is taken out from the pinion gear 2 and transmitted to the main gear 5 of the first swing mechanism 4 via the transmission gear train 3.
The process until the swing lever 6 and the swing gear 7 are moved counterclockwise is the same as in the normal photographing process described above.

However, in the above case, since the control lever 12 has moved inside the movement space of the swing gear 7, the pin 8 comes into contact with the tip 12a of the control lever 12, preventing further reaction of the swing gear 7. Movement in a clockwise direction will be blocked.

On the other hand, when the control lever 12 is moved as described above, the control gear 14
has moved to the illustrated position indicated by the solid line where it can mesh with the swing gear 7. Therefore, the swing gear 7 will mesh with the control gear 14 if its movement is prevented as described above.

Therefore, the reverse rotation output of the motor M is transmitted to the intermediate gear 13 via the control gear 14 and further to the tripod screw member 16 via the gear portion 18.

The tripod screw member 16 has a locking recess 19 and a locking member 2.
As mentioned above, the engagement with the tip portion 20b of the motor M is disengaged, and therefore, the control gear 14, the intermediate gear 13, and the tripod screw member 16 are It will rotate in the direction shown by the broken line.

At this time, if the tripod screw hole 17 of the tripod screw member 16 is fitted with a tripod screw (not shown), the tripod screw member 16 cannot rotate. is provided via a mechanism, and therefore, in this case, the intermediate gear 13 revolves around the gear portion 18 of the tripod screw member 16.

That is, the camera body B rotates around the tripod screw member 16.

As a result, the panoramic camera according to the present invention can operate the shutter when mounted on a tripod, perform a partial winding operation by the forward rotation of the motor M, and rotate the camera body B corresponding to the photographing angle of view of the photographing lens R by the reverse rotation of the motor M. By performing the operations several times in the above order, for example, panoramic photography can be performed.

Furthermore, as is clear from the above procedure, when performing panoramic photography, it is necessary to reverse the motor M in order to rotate the camera body B even when using the intermediate frame of the film F.
Therefore, the spool L is completely separated from the drive system, and there is a risk that the shooting ranges will overlap due to the occurrence of rewinding due to the elasticity of the film F. However, in the case of the present invention,
As mentioned above, there is provided an unwinding prevention means 1b, which is a ratchet mechanism, for example, which applies a certain amount of load to the rotation of the spool 1 in the unwinding direction in the above state, and the operation of this means 1b prevents the above-mentioned disadvantages. There is no need to explain in detail that this is prevented.

Moreover, regarding the rewinding operation of the film F in the above case, the switching lever 27 of the operating means 22 is slid to the left,
Needless to say, this can be done by moving the control lever 12 and the control gear 14 clockwise and then rotating the motor M in the reverse direction.

As briefly described above, the panoramic camera of the present invention can switch between general photography and panoramic photography simply by switching the operating means.

In addition, the well-known film winding built into the spool,
The rewind motor is used as a rotational drive source for the camera body during panoramic shooting using the first and second swing mechanisms, which simplifies the structure and does not significantly increase the size of the device.
There is no cost increase.

FIG. 2 is a plan view including a partial cross section showing the main parts of a specific embodiment of a panoramic camera that has yet to be invented. In the figure, the same reference numerals and numbers as in FIG. 1 indicate the same functional configuration. , detailed explanation will be omitted.

As is clear from FIG. 2, this specific embodiment has almost the same general configuration as the panoramic camera according to the present invention explained in FIG. Let's talk about its structure.

The pinion gear 2 provided on the output shaft of the motor M in the spool 1 is a stepped gear: 9 a N 3 b N 3 C
meshing with the gear 3a of the transmission gear train 3 consisting of %3d;
Further, the gear 3a of the gear train 3 meshes with a main gear 5 forming a part of the first swing mechanism 4.

At the lower part of the spool 1, an unwinding prevention means 1b is formed, which is a friction mechanism or a ratchet mechanism as shown in FIG. 4, FIG. 5, and FIGS. 6(a) and (b), for example.

The friction mechanism example shown in FIG. 4 is a schematic cross-sectional view, and shows an operating member 22 for switching between the general shooting mode and the panoramic shooting mode.
A control lever 44 that moves in conjunction with the switching lever 27 and has step portions 44a and 44b of different heights, a tip portion 46a that comes into contact with the step portions 44a and 44b, and a gear portion that meshes with the gear portion 1a of the spool 1. 46b and a friction gear member 46 having a storage recess 46c for a spring 45 to be described later;
The surface 47a of the fixed base 47 and the lower surface 46 of the storage recess 46c
d and a spring 45 that is provided in contact with both of the friction gear members 46 and always biases the friction gear member 46 downward.

Therefore, the load supply state with respect to the rotation of the spool 1 is controlled by the contact state between the stepped portions 44a, 44b of the control lever 44 and the tip end portion 46a of the friction gear member 46.

That is, the distal end portion 46a is the stepped portion 44 with a low height.
b, the spring 45 is extended and almost no friction occurs between the lower surface 46d and the surface 47a, and the spool 1 meshing with the friction gear member 46 is easily moved. It is controlled so that it can rotate.

Further, when the illustrated tip portion 46a is in contact with the tall step portion 44a, the spring 45 is compressed, and the lower surface 46d and the surface 47a are brought into contact based on the elastic force of the spring 45. As a result, friction is generated between the two surfaces, and the spool 1 meshing with the friction gear member 46 is controlled to be in a state where it cannot easily rotate.

Therefore, when the switching lever 27 of the operating means 22 is switched to the panoramic shooting mode, the state shown in the figure is obtained, and when the switching lever 27 is switched to the general shooting mode, the state in which the tip portion 46a is in contact with the low step portion 44b is obtained. By interlocking the switching lever 27 and the control lever 44, it is possible to prevent the film F from rewinding, which causes problems due to its elasticity.

As is clear from the figures, the ratchet mechanism shown in a schematic side view in FIG. 5 and in a bottom view and partially schematic side view in FIGS. The ratchet gear 48.51 is provided on the lower side surface 1d different from the formation position of the portion 1a, and the ratchet gear 48.51 is rotated in the direction of the arrow X1 or Y.
The relationship between the ratchet gear 4 and the ratchet gear 4 is controlled.
8.51 and a ratchet pawl 49.52 which is rotatably controlled between the illustrated position where it can act and a position where it cannot act, and which moves in conjunction with the movement of the switching lever 27 of the operating means 22. and a pawl control lever 50.53 that controls the rotation of the lever.

Therefore, when the switching lever 27 is switched to the panoramic shooting mode, the ratchet pawls 49 and 52 are connected to the ratchet gear 4.
The interlocking relationship between the pawl control lever 50.53 and the switching lever 27 is controlled so that the lever 50. By doing so, it is possible to prevent unwinding, which would cause problems due to the elasticity of the film F, as with the previous friction mechanism.

Now, the swinging lever 6 in this embodiment, which forms the first swinging mechanism 4 together with the main gear 5, has first and second swinging gears 7a and 'yb that mesh with and rotate with the main gear 5. There is.

tJl, the second swing gears 7a, 7b are fitted so that the bins 8a, 8b provided on their rotating shafts can slide into long grooves 30, 31 provided in a fixed base (not shown). and its range of movement is regulated.

The first swing gear 7a is configured to mesh with a gear portion 1a provided integrally or fixedly on the outer periphery of the spool 1 in the illustrated state in which the pin 8a is located at the left end of the long groove 30.

The second swing gear 7b meshes with the gear 9 when the bin 8b is moved from the illustrated state at the left end of the long groove 31 to the right end.

The gear 9 is a second gear consisting of gears 1oa11ob11oc.
It is connected to a gear portion 11a of the rewinding shaft 11 via a transmission gear train 1o.

The control gear 14 is the long arm portion 12 of the abbreviated control lever 12.
a, and revolves around the intermediate gear 13 as the control lever 12 rotates.

Note that the revolution range of the control gear 14 is regulated by a bin 14a provided on its rotating shaft and a long groove 32 formed in a fixed base (not shown), similar to the first swing gear 7a and the like. .

The short arm portion 12b of the control lever 12 is provided with a spring member 21a corresponding to the spring 21, which was shown as a single member in the above schematic configuration, and constantly biases the control lever 12 in the counterclockwise direction.

Incidentally, the state shown in the drawing obtained by this urging is a state in which the tip of the long arm portion 12a is moved into the movement space of the bin 8b of the second swing gear 7b, as described above. .

Therefore, the second swing gear 7b is the gear 9 in the illustrated state.
The pin 8b cannot be moved to a position where it engages with the control gear 14, and the pin 8b is positioned in the middle of the long groove 31 as shown by the dashed line in the figure, and is engaged with the control gear 14.

Tip part 2 that engages with the locking recess 19 of the tripod screw member 16
The locking member 2o having a diameter of 0b is rod-shaped in this embodiment, and is always biased counterclockwise by a spring member 21b corresponding to the spring 21 shown as a single member in the above schematic configuration. has been done.

A switch member 33 that opens and closes in response to the rotation of the locking member 20 is provided on the right side of the locking member 20 in the drawing.

This switch member 33 is opened when the distal end 20b of the locking member 20 and the locking recess 19 are disengaged,
Further, it is closed when the above-mentioned fitting is performed, and both of the above-mentioned states are inputted to a motor drive circuit C that controls forward and reverse operations of the motor based on the operating state of the camera and the like.

The intermediate gear 13 that meshes with the gear portion 18 of the tripod screw member 16 forms a photo interrupter 35 for detecting the rotational state of the intermediate gear 13 via an appropriate transmission gear train 34 consisting of gears 34a, 34b, and 34c. It is also connected to the gear portion 36a of the slit member 36.

The photocoupler 37, which together with the slit member 36 forms the photoink converter 35, detects the plurality of slits 36b provided in the slit member 36.

The switching lever 27 constituting the operating means 22 has an oval shape in this embodiment, and is provided between support stands 39 and 40 so as to be able to slide in the left and right directions in the drawings. and is connected to an operating member 38 provided between the support base 40 and the external mold 41 of the camera.

Next, an example of the operation of the specific embodiment described above will be explained based on the operation flowchart shown in FIG.

The basic operation is the same as the schematic configuration explained in FIG. , the first rocking gear 7a meshes with the gear portion 1a of the spool 1 and becomes in a state where it can wind up the film, and conversely, the motor M reverses and the clockwise rotational output shown by the broken line in the figure is taken out from the pinion gear 2. Then, the second swing gear 7b is engaged with the gear 9 or the control gear 14 based on the state of the operating means 22, and is brought into a state where it can rewind the film or transmit a reverse rotation output to the tripod screw member 16. Become. There is no need to explain in detail that the load supply state for the rotation of the spool 1 is controlled by the rewind prevention means 1b based on the state of the operating means 22. When it is closed, the motor M is rotated in the normal direction by the motor drive circuit C as is well known, and an initial winding operation of, for example, three frames is performed.
The camera is put into a shooting ready state.

Next, the switching lever 27 of the operating means 22 is moved to the operating member 38.
When the general photography mode is set by sliding the control lever 12 to the left in the drawing up to the dashed line state, the control lever 12 is moved out of the movement space of the second swing gear 7b and the locking member 20
moves to a position where the tripod screw member 16 is locked.

When the shirt release button is fully pressed in this state, the focus of the photographing lens R is adjusted (AF stage setting is followed by the shutter operation), and then the open/close motor of the switch member 33 determines whether or not the panorama mode is selected. This is confirmed by detection in the drive circuit C.

The switch member 33 is in the closed state indicating the general shooting mode, and therefore, in this case, the camera's motor drive circuit C
The motor M is rotated in the forward direction, and the first swing gear 7b and the gear portion 1a of the spool 1 are engaged to wind up one frame of the film F.

When the winding of one frame is completed, the mode is checked again by the switch member 33, and since it is the general photography mode, the camera returns to the previous photography preparation state.

Incidentally, when the last frame of the film F is detected during the winding operation, the motor M is reversely rotated by the motor drive circuit C, and the second
The film F
will be automatically rewound.

Next, regarding the case of performing panoramic photography, in this case, the switching lever 27 of the operating means 22 is switched to the state shown in FIG. 2, that is, the solid line state in the camera that is in the photography preparation state. Note that the above camera has a tripod screw member 16.
It is assumed that the tripod screw hole 17 of is engaged with a tripod (not shown).

By switching the switching lever 27 to the illustrated state, the long arm portion 12a of the control lever 12 moves into the movement space of the second swing gear 7b, and the locking member 20 releases the locking of the tripod screw member 16. do.

At the same time, the switch member 33 is opened by the movement of the locking member 20, and inputs information to the motor drive circuit C that it is the panoramic mode.

Next, although it was not mentioned in the previous explanation, manually select the shooting angle and the number of frames to be shot, taking into account the shooting angle of view of the shooting lens R, that is, the range to be shot, or By detecting the focal length of the lens R, it is automatically input to the motor drive circuit C.

When the shirt release button is fully pressed in this state, the focus adjustment and shutter operation are performed as in the previous case, and then whether or not the panoramic mode is set is confirmed by detecting the state of the switch member 33.

In this case, the switch member 33 is in an open state indicating the panorama mode, and therefore the motor drive circuit C of the camera reverses the motor M through the meshing of the second swing gear 7b and the control gear 14. Thus, the reverse rotation output of the motor M is transmitted to the intermediate gear 13 and the tripod screw member 16.

As a result, the camera body B rotates around the tripod screw member 16, and the rotation of the motor M is stopped by the motor drive circuit C when the rotation angle reaches the previously set shooting angle. This will cause it to stop.

Next, the camera's motor drive circuit C causes the motor M to rotate forward in order to wind the film F, and as in the previous case, the first swing gear 7a and the gear portion 1a of the spool 1 are engaged with each other. One frame winding operation of the film F is performed.

When the above-mentioned winding operation is completed, the camera is confirmed to be in panorama mode again, and after confirming whether the number of shots taken so far has reached the number of shots set earlier, if it has not reached the number of shots set earlier, the camera starts focusing again Repeat this operation, and if it reaches the target, return to the shooting preparation state.

When the final frame is detected during the winding operation of the film F, the motor drive circuit C stops the normal rotation of the motor M, thereby stopping the winding operation, and further closes the switch member 33 in this state. That is, when the switching lever 27 is switched to the general photographing mode, the motor drive circuit C reverses the motor M, and as a result, the film F is automatically rewound as in the previous case.

In addition, in this embodiment where the film is forcibly rewound, the motor M
By providing a conventionally well-known rewinding member for instructing the camera body B in this embodiment as well, for example, the switching lever 27 can be switched to the general shooting mode at an appropriate time and the switch member 33 can be placed in the closed state. It goes without saying that the film F can be rewound at the appropriate time by operating the rewinding member at the same time.

With the operation described above, the embodiment shown in FIG.
You can switch between general photography and panoramic photography.

Effects of the Invention The panoramic camera according to the present invention is provided with a tripod screw member that can be rotated with respect to the main body, and the forward and reverse rotation outputs of the well-known film winding and rewinding motors built into the spool can be controlled based on the operation of the operating means. Since it is equipped with a first swing mechanism, a second swing mechanism, etc. that selectively transmits information to the spool, unwinding shaft, and the tripod screw member, general shooting and panoramic shooting can be performed by simply operating the operating means. It has an effect that can be performed by switching.

Furthermore, since there is no need to provide a special drive source for panoramic photography, the configuration can be simplified and miniaturized, and the cost can therefore be reduced.
