Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera provided with a barrier for protecting a lens barrel housed in a camera body.

[0002]

2. Description of the Related Art In a camera having a built-in lens barrel with a built-in photographing lens, an outer barrier (hereinafter referred to as a barrier) is provided on the front surface of the lens barrel to protect the photographing lens. There is. In such a camera, a lock mechanism is provided to lock the movement of the barrier so that the barrier does not move toward the lens barrel while the lens barrel is being extended from the camera body. The operation of the mechanism has been devised so that only one operation is required.

[0003]

However, even in a camera with a barrier, before shooting, the barrier is first retracted from the front of the lens barrel, and then the lens barrel is extended. Since the operation of returning the barrier to the front of the lens barrel is performed after the barrel is retracted into the camera body, the operation is complicated.

On the other hand, a camera is not merely a simple operation, and a camera having a strong recreational element can realize that the user is operating while grasping the state of the camera. It is also important.

[0005] In view of the above problems, an object of the present invention is to provide a camera which is provided with a barrier and a mechanism for preventing movement of the barrier when the lens barrel is being extended, and which is easy to operate. Another object of the present invention is to provide a camera which can satisfy the user's operational feeling in such a camera.

[0006]

In order to solve the above-mentioned problems, the invention according to claim 1 of the present invention is configured to be stored in a camera body and driven by a drive source in the camera body. When the lens barrel is retracted within the camera body, the lens barrel being movable between a closed position, which is the front surface of the lens barrel, and an open position retracted from the closed position. Moving to the open position before the lens barrel is extended from the camera body,
A barrier, the lens barrel is movable with the lens barrel, and when the lens barrel is stored in the camera body, the lens barrel is at a position where the movement of the barrier is not blocked, and the lens barrel is moved from the camera body. A camera provided with a blocking member that moves to a position where the barrier is prevented from moving so that the barrier cannot come into contact with the lens barrel when extended, wherein the barrier has a first conductive property. A conductive portion is provided, and the camera body is provided with a conductive second conductive portion capable of contacting with the first conductive portion, and the first conductive portion and the second conductive portion are provided. When the parts come into contact with each other, the lens barrel is extended from the camera body by the drive source, and the first conductive part and the second conductive part are in contact with each other. The lens barrel The first conductive portion and the second conductive portion are stored in the camera body, and when the barrier moves from the closed position to the open position, the barrier substantially reaches the open position. And when the barrier moves from the open position to the closed position, the barrier separates when slightly moved from the open position to the closed position side.

According to the camera of the first aspect, when the barrier in the closed position, which is the front surface of the lens barrel housed in the camera body, moves to the open position, the barrier provided on the barrier. The first conducting portion and the second conducting portion provided on the camera body come into contact with each other, and the lens barrel is extended from the camera body by a driving source in the camera body. When the barrier returns from the open position to the closed position, when the barrier moves slightly from the open position to the closed position, the first and second conducting portions are separated from each other, and the lens barrel is moved by the drive source to the camera. Stored in the main body. Moreover, if the lens barrel is extended,
The blocking member also moves to a position where it blocks movement of the barrier so that the barrier cannot contact the lens barrel. Therefore, when the barrier is moved, the lens barrel is also extended from the camera body with the blocking member or stored in reverse, so that the user only needs to open and close the barrier. Also, since the blocking member can be driven,
Operation becomes simple.

Here, the barrier may be moved manually or automatically by operating a switch or the like. In addition, the first conductive portion and the second conductive portion
Each of them is made of a material having conductivity, and a portion having no conductivity may be provided in a part thereof, or may be made of a plurality of members. Furthermore, the specific shape and structure, or the mounting position are completely arbitrary, in short, by moving the barrier, contact or separation,
What is necessary is just to be able to function as a switch for controlling the operation of the drive source. The drive source can be electrically controlled, and includes, for example, a motor and an electromagnet.

According to a second aspect of the present invention, in the camera according to the first aspect, the barrier is formed along a direction of movement of the barrier, and guides the second conductive portion.
A guide portion is provided, and when the barrier moves from the closed position to the open position, the first conductive portion moves in a direction approaching the second conductive portion, and the barrier moves from the open position. When moving to the closed position, the first conductive portion moves in a direction away from the second conductive portion.

According to the camera of the second aspect, the direction of movement of the barrier is guided by using the second conducting portion and the guide portion formed on the barrier itself, so that the operation of the barrier is smooth. It will be.

Here, the guide portion formed in the barrier is, for example, an elongated concave portion. When the barrier slides right and left, the guide portion is formed linearly and is configured to rotate. May be formed in an arc shape. Further, it may be formed to include a plurality of grooves as needed.

According to a third aspect of the present invention, in the camera according to the second aspect, the barrier is configured to be able to manually reciprocate in one direction, and the second conductive portion is provided with a pair of conductive portions. A pair of conductive members,
The first conductive portion is urged by an urging member to approach each other, and the first conductive portion has a shape capable of simultaneously contacting each of the pair of conductive members, and the guide portion is formed of the pair of conductive members. Each of the two rows of guide paths guides each of the pair of conductive members at the start and end of the movement of the barrier between the open position and the closed position. It is characterized by a shape that must move away from each other and then approach each other.

According to the third aspect of the camera, the pair of conductive members forming the second conductive portion are urged by the urging member so as to approach each other, and are formed on the barrier. Two rows of guide paths for guiding the pair of conductive members are:
At the beginning and end of the movement of the movement of the barrier, the pair of conducting members are separated from each other, and thereafter, they must operate to approach each other.
For example, when the user attempts to manually move the barrier from the closed position to the open position, the user first operates the urging force of the urging member to move the pair of conducting members away from each other. Must be strong,
I feel some resistance. After that, however, the user may be operated so as to approach each other, and the urging force of the urging member can be used, so that the user is released from resistance. When the barrier has almost reached the open position, the user also feels resistance and then feels free from the resistance. The same applies when returning the barrier from the open position to the closed position. Therefore, when operating the barrier, unless the user applies a conscious force against the biasing member, the barrier does not start moving, and also, at the end of the movement, after feeling a little resistance, Since the user is released from the resistance, it is possible to realize that the user has reached the closed or open position. Further, when viewed from the camera side, since a force against the urging member is required at the start and end of the movement, the barrier is not easily opened and closed.

According to a fourth aspect of the present invention, in the camera according to the third aspect, when the barrier moves from the open position to the closed position, the pair of conductive members are separated from each other at the beginning of movement. Then, when they start to approach each other, the first conductive portion and the pair of conductive members are separated from each other, and the blocking member is the pair of conductive members immediately after being separated from the first conductive portion. When the lens barrel is stored in the camera body, the lens barrel moves to a position where the approach of the pair of conductive members is not prevented.

According to the camera of the fourth aspect, when trying to move the barrier from the open position to the closed position, the pair of conducting members guided by the guide path of the barrier are separated from each other, and thereafter, When you start to approach each other,
Then, the lens barrel starts to be retracted into the camera body. Immediately after that, the blocking member prevents the pair of conductive members from approaching each other, so that the barrier is also prevented from moving at a position corresponding to the position where the pair of conductive members starts to approach each other. When the lens barrel is stored in the camera body, the blocking member moves to a position where the pair of conductive members does not prevent the approach of the pair of conducting members, and therefore, the movement of the barrier in the closing position direction is not prevented. In other words, while the lens barrel is being extended, the barrier is indirectly prevented from moving through the pair of conducting members of the camera body, and the lens barrel is damaged by the barrier.
Can be prevented.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a camera according to the present invention will be described.
This will be described with reference to the drawings. 1 and 2 show an example of an embodiment of a camera according to the present invention.

This camera has a built-in photographic lens and has a lens barrel 3 incorporated in a cylindrical fixed ring 2 (FIG. 10) provided substantially at the center of the camera body 1. The lens barrel 3 is formed by overlapping a plurality of cylindrical rings such as an outer ring 4 and a moving ring 5, and has a photographing lens (not shown) attached inside, and is parallel to the optical axis direction of the photographing lens. It is possible to move to. Camera body 1
Is provided with a drive motor (drive source) (not shown). When a main switch described later is turned on, the drive motor operates, whereby the lens barrel 3 is extended from the camera body 1, and conversely, the main switch is turned on. When the drive motor is switched from ON to OFF, the drive motor operates again, so that the drive motor is moved back and stored in the camera body 1.

As shown in FIG. 1, the lens barrel 3 of the camera body 1
Is provided with a flat barrier 8 on the front surface. The barrier 8 is located at the front of the lens barrel 3 (closed position) when not photographing, and protects it. The barrier 8 is fitted into the cover 30 by a guide or the like (not shown) formed on the back surface so as to be slidable left and right. Then, by manually moving it to the right position to the position shown in FIG. 2, it is retracted from the front surface of the lens barrel 3. When the metal sides 12b, 12b, which will be described later, are pushed by the conductive pins 16 and 17 and come into contact with a part 9a of the ridge at the time of this evacuation, the barrier 8 cannot slide any further. At the position (open position).

As shown in FIG. 3 (a), two guide grooves (guide paths) 11, 11 defined by ridges 9 and 10 are formed on the back surface of the barrier 8. The guide grooves 11, 11 are formed substantially parallel to each other, but have left and right ends separated from each other. FIG.
In the vicinity of the left ends of the ridges 10 and 10,
a and 10a are formed. As shown in FIG. 4, the right ends of the ridges 10 and 10 have two corners 1 respectively.
0b and 10c are formed.

In addition, at the right end of the guide grooves 11, 11,
The section 12 (first conductive portion) is attached. The section 12 includes a support portion 12a and metal pieces 12b and 12b.
It is attached to the barrier 8 while being fixed by 13 (FIG. 3B). The metal pieces 12b, 12b, which have a thin plate shape, extend vertically from one end of the support portion 12a and substantially abut on the right corners 10c, 10c of the ridges 10, 10. The metal pieces 12b, 12b can be bent rightward until they come into contact with a part 9a of the ridge 9, as shown by the phantom line in FIG.

As shown in FIGS. 5 and 6, a first movable lever 14 and a second movable lever 15
(A pair of conducting members) are attached so as to be vertically arranged. FIG. 5 shows these levers 14 and 15 with the cover 30 removed. The first movable lever 14 and the second movable lever 15 are both formed of a conductive material, and their side portions are electrically connected to each other by press-fitting or caulking as shown in FIGS. Conductive pins 16 and 17 having a property are attached. Both the first movable lever 14 and the second movable lever 15 are electrically connected to a single circuit board (not shown), and are provided on the circuit board when the conduction between the conduction pins 16 and 17 becomes conductive. The main switch is turned on. When the conduction between the conduction pins 16 and 17 is changed from the conduction state to the non-conduction state, the main switch is turned off. The conduction pins 16 and 17 are inserted through substantially rectangular holes 30 a and 30 a formed in the cover 30, and the movement of the first movable lever 14 and the second movable lever 15 is controlled by the movement of the pins 16 and 17.
Is regulated along the holes 30a, 30a so that it is only in the vertical direction.

As shown in FIGS. 7 and 8, on the back surfaces of the first movable lever 14 and the second movable lever 15, spring hooks 14a and 15a are provided. A lever spring 18 is hung on these spring hooks 14a and 15a, and the levers 14 and 15 are urged by the lever spring 18 in a direction approaching each other. By the way, the spring hooks 14a and 15a are connected to the levers 14 and 1 via the lever spring 18.
5 does not conduct. In this embodiment, the spring hook 14a of the first movable lever 14 is formed from an insulating material, while the spring hook 15a of the second movable lever 15 has a standing bent portion formed on the lever 15 itself. Spring hook 15a was used.

The conductive pins 16 and 17 are fitted in the two guide grooves 11 and 11 described above. The sliding movement of the barrier 8 causes the guide grooves 11 and 11 to move up and down.
11 relatively move. The vertical movement of the conductive pins 16 and 17 is caused by the lever spring 1 in the direction approaching each other.
By the urging force of No. 8, the operation is performed smoothly without any external force, but a force opposing the urging force of the lever spring 18 must be applied in the separating direction. That is, the user who moves the barrier 8 makes a movement such that the conduction pins 16 and 17 fitted on the back surface of the barrier 8 are separated from each other.
In this case, a force against the lever spring 18 must be applied.

When the barrier 8 is at the closed position, the conductive pins 16 and 17 are fitted into the right ends (FIG. 5) of the guide grooves 11 and 11. If the positions of the conduction pins 16 and 17 at this time are described with reference to FIG. 3, they are outside the protrusions 10a and 10a. At this time, as shown in FIG. 9A, the conduction between the pins 16 and 17 is non-conductive, and the main switch is OFF.

When the barrier 8 moves from the closed position to the vicinity of the open position, the conduction pins 16 and 17 first move to the ridges 10 and
It comes into contact with the outer corners 10b, 10b of 10 (position C in FIG. 4) and comes into contact with the metal pieces 12b, 12b of the section 12. At this time, the conduction between the conduction pins 16 and 17 becomes conductive, and the main switch is turned ON (FIG. 9).
(B)). When the pins 16 and 17 reach the position D where the metal sides 12b and 12b abut on the part 9a of the ridge 9,
The barrier 8 cannot move any further.
When the barrier 8 returns from the open position to the closed position, the pins 16, 1
When the metal piece 7 is separated from the metal pieces 12b, the main switch is turned off, and the lens barrel 3 is retracted into the camera body 1. The pins 16 and 17 can approach to the position B by the urging force of the lever spring 18, but the lock member 6 is completely moved from between the first movable lever 14 and the second movable lever 15 as described later. If it does not come off, it will not be accessible anymore, ie
In a state where 17 is at the position B, the movement of the barrier 3 is prevented.

In this camera, a locking member (blocking member) 6 that locks the operation of the barrier 8 to prevent the barrier 8 from being closed when the lens barrel 3 is extended from the camera body 1 includes: As shown in FIG. 10, it is provided near the outer surface of the fixed ring 2.

The lock member 6 is a long plate member whose front portion is bent in a crank shape and whose width in the vertical direction is such that the conductive pins 16 and 17 are at the position B in FIG. Of the first movable lever 14 and the second movable lever 15
The length is approximately the same as the distance between the side portions, and if the tip portion 6a enters between the levers 14 and 15, it is possible to prevent them from approaching each other.

An L-shaped locking portion 6b is formed on the lock member 6, and one end of a spring 7 is hung on the locking portion 6b. The other end of the spring 7 is hung on a locking pin (not shown) of the camera body 1, whereby the lock member 6 is urged forward by the spring 7.

At the rear end of the lock member 6, there is formed a contact portion 6c which is bent toward the lens barrel 3 side.
When the lens barrel 3 is stored in the camera body 1, the contact portion 6 c is in contact with the rear end of the movable ring 5 of the lens barrel 3. Thus, the lock member 6 is fixed at a position retracted from between the levers 14 and 15 against the urging force of the spring 7. Further, when the lens barrel 3 is extended from the camera body 1 and the moving ring 5 moves forward, the lock member 6 cannot be prevented from moving forward, and moves forward by the urging force of the spring 7, Lever 1
It enters between 4 and 15, contacts the cover 30,
It stops (the state of FIG. 6B). When the lens barrel 3 is stored in the camera body 1 again, the abutting portion 6c is abutted by the rear end of the movable ring 5, and the locking member 6 is pushed rearward against the urging force of the spring 7. And return to the original position.

The operation of the camera having the above configuration will be described. (1) When moving the barrier to the open position When the user applies a rightward force from the state shown in FIGS. 1 and 5 to open the barrier 8, the conductive pins 16 and 17 are brought into contact with the protrusions 10a, I feel a little resistance in contact with 10a. However, when further force is applied, the levers 14 and 15 move up and down in a direction away from each other, and the conductive pins 16 and 17
a, get over 10a. At this time, the user feels as if he / she is released from the resistance and the operation of the barrier 8 is lightened. The conduction pins 16 and 17 are temporarily connected to the projections 10a and 10a.
Is exceeded, by the urging force of the lever spring 18,
Naturally, the conductive pins 16 and 17 move up and down along the guide grooves 11 and 11 in a direction approaching each other, and the barrier 8 naturally moves rightward. Further, if the user presses the barrier 8 lightly to the right, the barrier 8 slides as it is. The conductive pins 16 and 17 relatively pass through the guide grooves 11 and 11 and approach the direction in which the section 12 is attached.

When the positions of the conductive pins 16 and 17 reach the position A in FIG. 4, the guide grooves 11 and 11 are separated from each other, so that the user can resist the urging force of the lever spring 18. When a little force is applied to the
6 and 17 move away from each other and the barrier 8 slides further to the right. The conductive pins 16 and 17 are connected to the corners 1 of the ridges 10 and 10.
0b, 10b, it comes into contact with the metal pieces 12b, 12b, and at this time, the main switch is turned on via the first movable lever 14 and the second movable lever 15, the drive motor operates, and the lens barrel 3 Is fed out of the camera body 1.
When the lens barrel 3 is extended, the lock member 6 moves forward by the urging force of the spring 7, and the tip portion 6a enters between the first movable lever 14 and the second movable lever 15 (FIG. 6).
(B)). Since the tips of the ridges 10, 10 are inclined obliquely to the right, if the barrier 8 is lightly pushed to the right, the levers 14, 15 can easily approach by the urging force of the lever spring 18, and the conduction pins 16, 17 The metal pieces 12b, 12b are further pushed while exceeding the corners 10b, 10b,
When b and 12b come into contact with a portion 9a of the ridge 9, the barrier 8 stops, reaches the open position, and is in the state of FIG.

(2) When returning the barrier to the closed position When the user applies a leftward force to the barrier 8 in order to close the barrier 8 from the state shown in FIG. Return to position C of FIG. At this time, the user moves the first movable lever 1 against the urging force of the lever spring 18.
Since a force is applied so that the distance between the fourth movable lever 15 and the second movable lever 15 is increased, a little resistance is felt.
Beyond that, since the shape of the guide grooves 11, 11 is such that the levers 14 and 15 approach each other, the lever spring 18
The user can be released from resistance. When the conduction pins 16 and 17 start to descend from the position C, they are separated from the metal pieces 12b and 12b, whereby the main switch is turned off. When the main switch is turned off, the drive motor operates and the lens barrel 3 starts to be retracted into the camera body 1. The barrier 8 advances to the left by the urging force of the lever spring 18, but the conduction pin 1
When the members 6 and 17 reach the position B, while the lock member 6 prevents the first movable lever 14 and the second movable lever 15 from approaching each other, they are stopped, and the lens barrel 3 is retracted. The lock member 6 also moves backward by being pushed by the movable ring 5, and moves to the left by the urging force of the lever spring 18 when it is displaced from between the first movable lever 14 and the second movable lever 15. Furthermore, if the user pushes lightly to the left,
The barrier 8 slides while the conduction pins 16 and 17 relatively move along the guide grooves 11 and 11. When the barrier 8 approaches the closed position, the guide grooves 11, 11 are shaped to move away from each other.
The barrier 8 moves further to the left by applying a force that opposes the urging force of. Pins 16 and 17 are projections 10a,
If it exceeds 10a, by the urging force of the lever spring 18,
The user is released from the resistance, the conduction pins 16 and 17 return to their original positions, and the barrier 8 is in the state shown in FIG.

According to the above-described camera, when the barrier 8 moves, the lens barrel 3 is pulled out from the camera body 1 with the lock member 6 or stored in the opposite direction with the lock member 6. If the user only opens and closes the barrier 3, the lens barrel 3 also locks the movement of the barrier 8 with the locking member 6.
Can also be driven, so that the operation is simplified. In addition, since the direction of movement of the barrier 8 is guided by using the conductive pins 16 and 17 and the grooves 11 formed in the barrier 8 itself, the operation of the barrier 8 is smooth.

When the user attempts to manually move the barrier 8 from the closed position to the open position, first, the first movable lever 14 and the second movable lever 15 are moved.
In order for the user to move away from each other, the user must apply force against the urging force of the lever spring 18,
I feel some resistance. However, after that, the lever spring 18
The user can be released from resistance because the urging force can be used. When the barrier 8 has almost reached the open position, the user also feels resistance and is then released from the resistance. The same applies when the barrier 8 is moved from the open position to the closed position. Therefore, the barrier 8 does not start to move unless a conscious force against the lever spring 18 is applied when the barrier 8 is operated. It is possible to feel that the closed or open position has been reached. Therefore, it is possible to satisfy the user's feeling that the user is operating while checking the state of the camera. Also, when viewed from the camera side, since a force against the lever spring 18 is required at the start and end of the movement, the barrier 8 is not easily opened and closed, and the photographing lens may be damaged due to carelessness or the like. I will not do it.

In addition, while the lens barrel 3 is being extended,
The barrier 8 is indirectly prevented from moving through the conduction pins 16 and 17 of the camera body 1, and can prevent the lens barrel 3 from being damaged by the barrier 8.

In the above embodiment, the size, shape, and the like of each part of the camera can be appropriately changed, and the specific detailed structure is of course arbitrary. For example, the barrier is retracted from the front surface of the lens barrel by sliding, but may be configured to rotate and the lock member controls the operation of the first movable lever and the second movable lever. Although the operation of the barrier is prevented by blocking, the operation of the barrier may be directly prevented.

[0037]

According to the first aspect of the present invention, when the barrier moves, the lens barrel is also extended from the camera body or stored in reverse, so that the user can only open and close the barrier. All you have to do is to simplify the operation.

According to the invention described in claim 2, according to claim 1
In addition to the effects of the invention described in the above, since the direction of movement of the barrier is guided by using the second conductive portion and the guide portion formed on the barrier itself, the operation of the barrier is
It will be even smoother.

According to the invention set forth in claim 3, according to claim 2
In addition to the effects of the invention described in the above, when operating the barrier, unless the user applies a conscious force against the urging member, the barrier does not start moving, and the end of the movement is slightly You can feel the resistance, and then you can feel that you have been released from the resistance and reached the closed or open position,
While grasping the state of the camera of the user, it is possible to satisfy the feeling of operation.

According to the invention described in claim 4, according to claim 3,
In addition to the effects of the invention described in (1), the movement of the barrier is locked by the blocking member when the lens barrel is extended, and the lens barrel can be prevented from being damaged by the barrier.
