Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a camera including a barrier for protecting a lens barrel stored in a camera body.
[0002]
[Prior art]
In a camera with a built-in lens barrel in which a photographing lens is incorporated, an outer barrier (hereinafter referred to as a barrier) may be provided on the front surface of the lens barrel in order to protect the photographing lens. Such a camera is provided with a locking mechanism that locks the movement of the barrier so that the barrier does not move toward the lens barrel while the lens barrel is extended from the camera body. The mechanism has been devised so that only one operation is required.
[0003]
[Problems to be solved by the invention]
However, with a camera with a barrier, before shooting, first retract the barrier from the front of the lens barrel and then extend the lens barrel. After shooting, the lens barrel is retracted into the camera body. Since the operation of returning the barrier to the front surface of the lens barrel is performed, the operation is complicated.
[0004]
On the other hand, the camera is not just easy to operate, but it is also important for a camera with a strong entertaining factor that the user can feel that he is operating while grasping the state of the camera. It is.
[0005]
In view of the above problems, an object of the present invention is to provide a camera that includes a barrier and a mechanism that prevents the movement of the barrier when the lens barrel is extended, and that is simple to operate. It is another object of the present invention to provide a camera that can satisfy the user's operational feeling.
[0006]
[Means for Solving the Problems]
  In order to solve the above-described problems, an invention according to claim 1 of the present invention includes a lens barrel stored in a camera body and configured to be driven by a driving source in the camera body, and the mirror. It is possible to move between a closed position which is the front surface of the barrel and an open position retracted from the closed position, and the lens barrel is located in the closed position when stored in the camera body, A barrier that moves to the open position before the lens barrel is unwound from the camera body, the lens barrel being movable with the lens barrel, and when the lens barrel is stored in the camera body, Provided is a blocking member that is in a position that does not prevent the movement of the barrier, and moves to a position that prevents the movement of the barrier so that the barrier cannot contact the lens barrel when the lens barrel is extended from the camera body. Tortoise The barrier is provided with a first conductive portion having conductivity, and the camera body is provided with a second conductive portion that can contact the first conductive portion and has conductivity. When the first conduction part and the second conduction part come into contact with each other, the lens barrel is drawn out from the camera body by the drive source, and the first conduction part and the second conduction part come into contact with each other. When the lens is separated from the closed state, the lens barrel is housed in the camera body by the drive source, and the first conductive portion and the second conductive portion are configured such that the barrier is opened from the closed position. When moving to a position, the barrier comes into contact when the barrier reaches approximately the open position, and when the barrier moves from the open position to the closed position, the barrier slightly moves from the open position to the position. When moved to the closed position side, it is separatedConfiguration,
  The second conducting portion includes a pair of conducting members, and the pair of conducting members are urged by a urging member so as to approach each other, and the first conducting portion is the pair of conducting members. The barrier is formed along the direction of movement of the barrier, and is provided with two rows of guide paths for guiding the pair of conducting portions, The two rows of guide paths are arranged such that the pair of conducting members are separated from each other at the beginning and end of movement of the barrier between the open position and the closed position, and then approach each other. Must be working, is a shapeIt is characterized by that.
[0007]
According to the camera of claim 1, when the barrier in the closed position, which is the front surface of the lens barrel stored in the camera body, moves to the open position, the first conduction provided in the barrier is performed. And the second conducting portion provided in the camera body come into contact with each other, and the lens barrel is drawn out from the camera body by the drive 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 to the camera by the drive source. Stored in the body.
In addition, when the lens barrel is extended, the blocking member also moves to a position where the barrier is prevented from moving so that the barrier cannot contact the lens barrel.
Therefore, when the barrier is moved, the lens barrel is also drawn out of the camera body with the blocking member or stored in reverse, so that the user only needs to open / close the barrier. However, since the blocking member can also be driven, the operation is simplified.
[0008]
Here, the movement of the barrier may be performed manually, or may be configured to be performed automatically by operating a switch or the like.
Moreover, both the 1st conduction | electrical_connection part and the 2nd conduction | electrical_connection part consist of a material which has electroconductivity, and the part which does not have electroconductivity may be provided in part, and from several members It may be. Furthermore, these specific shapes, structures, or mounting positions are completely arbitrary, and in short, it is only necessary to function as a switch that controls the operation of the drive source by moving or moving away from the barrier. .
The drive source can be electrically controlled, and examples thereof include a motor and an electromagnet.
[0010]
  Also,Claim1According to the camera described in (1), since the direction of movement of the barrier is guided using the second conducting portion and the guide portion formed in the barrier itself, the operation of the barrier becomes smooth.
[0011]
Here, the guide portion formed on the barrier is, for example, an elongated concave portion, and when the barrier slides to the left and right, it is formed linearly and is configured to rotate. What is necessary is just to form in arc shape. Moreover, you may form so that it may consist of a some groove | channel as needed.
[0013]
  Furthermore,Claim1According to the camera described in (2), the pair of conducting members constituting the second conducting portion are urged by the urging members so as to approach each other, are formed in the barrier, and guide the pair of conducting members. The two rows of guide paths are shaped so that at the beginning and end of the movement of the barrier movement, the pair of conducting members must move away from each other and then approach each other. For example, when the user tries to manually move the barrier from the closed position toward the open position, the user first applies the biasing member so as to move the pair of conducting members away from each other. You have to put power against the power and feel some resistance. However, after that, since it is only necessary to operate so as to approach each other, the urging force of the urging member can be used, so that the user is relieved from resistance. Similarly, when the barrier reaches the almost open position, the user feels resistance and then feels free from that resistance. The same applies when returning the barrier from the open position to the closed position. Therefore, unless the user applies a conscious force against the biasing member during the operation of the barrier, the barrier does not start to move, and after feeling a little resistance about the end of the movement, Because you are free from the resistance, you can feel that you have reached the closed or open position. Further, when viewed from the camera side, a force against the urging member is required at the beginning and end of movement, and therefore the barrier is not easily opened and closed.
[0014]
  Claim2The invention described in claim1In the camera according to claim 1, when the barrier moves from the open position to the closed position, the first pair of conducting members are separated from each other at the start of movement, and then when the barriers start to approach each other, the first The conducting portion and the pair of conducting members are separated from each other, and the blocking member is in a position where the pair of conducting members can be prevented from approaching immediately after being separated from the first conducting portion. When stored in the main body, it moves to a position that does not prevent the pair of conductive members from approaching.
[0015]
  Claim2When the barrier is moved from the open position to the closed position, the pair of conducting members guided by the barrier guide path first move away from each other and then approach each other. In addition, since the first conducting portion and the pair of conducting members are separated from each other, the lens barrel starts to be retracted into the camera body at this time. Immediately after that, the blocking member prevents the pair of conducting members from approaching each other, so that the movement of the barrier is also blocked at a position corresponding to the position where the pair of conducting members start to approach each other. If the lens barrel is housed in the camera body, the blocking member moves to a position that does not block the approach of the pair of conducting members, so that the movement of the barrier in the closed position direction is not blocked. In other words, while the lens barrel is extended, the barrier is indirectly prevented from moving through the pair of conductive members of the camera body, and the lens barrel can be prevented from being damaged by the barrier. .
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the camera of the present invention will be described with reference to the drawings.
1 and 2 show an example of an embodiment of a camera of the present invention.
[0017]
This camera is a type of camera with a built-in photographic lens, and a lens barrel 3 is incorporated in a cylindrical fixed ring 2 (FIG. 10) provided almost at the center in 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. A photographing lens (not shown) is attached on the inside of the lens barrel 3. It is possible to move to. The 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 is operated, whereby the lens barrel 3 is drawn out from the camera body 1. When the main switch is turned from ON to OFF, the drive motor is actuated again so that it is retracted and stored in the camera body 1.
[0018]
As shown in FIG. 1, a flat barrier 8 is provided on the front surface of the lens barrel 3 of the camera body 1. The barrier 8 is in front of the lens barrel 3 (closed position) when it is not photographed, and protects it. The barrier 8 is fitted in the cover 30 so as to be slidable left and right by a guide or the like (not shown) formed on the back surface thereof. And it is made to evacuate from the front surface of the lens barrel 3 by moving to the position shown in FIG.
When the barrier 8 is retracted, when the metal sides 12b and 12b, which will be described later, are pressed by the conduction pins 16 and 17 and come into contact with the protruding portion 9a, the barrier 8 cannot slide any more. It stops at the position (open position).
[0019]
As shown in FIG. 3A, two guide grooves (guide paths) 11 and 11 defined by the protrusions 9 and 10 are formed on the back surface of the barrier 8. The guide grooves 11 and 11 are formed substantially parallel to each other, but the left and right ends are shaped to be separated from each other.
In FIG. 3, protrusions 10 a and 10 a are formed in the vicinity of the left ends of the protrusions 10 and 10. Further, as shown in FIG. 4, the right end portions of the protrusions 10 and 10 are shaped so that two corners 10b and 10c are formed, respectively.
[0020]
Further, a slice 12 (first conduction portion) is attached to the right end portion of the guide grooves 11 and 11. The section 12 includes a support portion 12a and metal pieces 12b and 12b, and is attached to the barrier 8 with the support portion 12a being fixed between the protrusions 10 and 10 by screws 13 and 13. (FIG. 3B). The thin metal plates 12b and 12b extend vertically from one end of the support portion 12a and are substantially in contact with the right corners 10c and 10c of the protrusions 10 and 10, respectively. The metal pieces 12b and 12b can be bent rightward until they abut against a part 9a of the protrusion 9, as indicated by phantom lines in FIG.
[0021]
As shown in FIGS. 5 and 6, the first movable lever 14 and the second movable lever 15 (a pair of conducting members) are attached to the back surface of the cover 30 so as to be lined up and down. FIG. 5 shows the levers 14 and 15 with the cover 30 removed.
Both the first movable lever 14 and the second movable lever 15 are made of a conductive material. As shown in FIGS. 7 and 8, the first movable lever 14 and the second movable lever 15 are electrically conductive by press-fitting or caulking. Conductive pins 16 and 17 are attached. Both the first movable lever 14 and the second movable lever 15 are electrically connected to one circuit board (not shown). When the conductive pin 16 and the conductive pin 17 are in a conductive state, the first movable lever 14 and the second movable lever 15 are provided on the circuit board. The main switch is turned on. The main switch is turned off when the conductive pins 16 and 17 are switched from the conductive state to the non-conductive state.
The conducting pins 16 and 17 are inserted through substantially rectangular holes 30a and 30a formed in the cover 30, and the movement of the first movable lever 14 and the second movable lever 15 is performed when the pins 16 and 17 are holes. By being along 30a, 30a, it is regulated so that it is only in the up-and-down direction.
[0022]
Further, as shown in FIGS. 7 and 8, spring hooks 14 a and 15 a are provided on the back surfaces of the first movable lever 14 and the second movable lever 15. A lever spring 18 is hooked on the 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 14 a and 15 a are configured such that the levers 14 and 15 are not electrically connected via the lever spring 18. In this embodiment, the spring hook 14a of the first movable lever 14 is formed of an insulating material, while the spring hook 15a of the second movable lever 15 is formed with a standing bent portion on the lever 15 itself, The spring hook 15a was used.
[0023]
The conduction pins 16 and 17 are fitted in the two guide grooves 11 and 11 described above, and move in the guide grooves 11 and 11 while moving in the vertical direction by sliding the barrier 8. The vertical movement of the conduction pins 16 and 17 is smoothly performed by the biasing force of the lever spring 18 in the direction close to each other without any external force, but resists the biasing force of the lever spring 18 in the separating direction. You must be able to apply power.
In other words, the user who moves the barrier 8 must apply a force against the lever spring 18 when the barrier 8 is caused to move away from the conductive pins 16 and 17 fitted on the back surface of the barrier 8. It has become necessary.
[0024]
When the barrier 8 is in the closed position, the conduction pins 16 and 17 are fitted into the right ends (FIG. 5) of the guide grooves 11 and 11. If the positions of the conductive 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 pins 16 and 17 are in a non-conductive state, and the main switch is OFF.
[0025]
When the barrier 8 moves from the closed position to the vicinity of the open position, the conduction pins 16 and 17 first come into contact with the outer corners 10b and 10b of the ridges 10 and 10 (position C in FIG. 4), and the section. The twelve metal pieces 12b and 12b are brought into contact with each other. At this time, the conducting pins 16 and 17 are in a conducting state, and the main switch is turned on (FIG. 9B).
When the pins 16 and 17 reach the position D where the metal sides 12b and 12b come into contact with the portion 9a of the protrusion 9, the barrier 8 cannot move any further.
When the barrier 8 returns from the open position to the closed position, when the pins 16 and 17 are separated from the metal pieces 12b and 12b, the main switch is turned off and the lens barrel 3 is drawn into the camera body 1. . The pins 16 and 17 can approach the position B by the urging force of the lever spring 18, but the lock member 6 is completely inserted between the first movable lever 14 and the second movable lever 15 as will be described later. Otherwise, the barrier 3 cannot be moved any more, that is, the movement of the barrier 3 is prevented with the pins 16 and 17 in the position B.
[0026]
In this camera, in order to prevent the barrier 8 from being closed when the lens barrel 3 is extended from the camera body 1, a lock member (blocking member) 6 for locking the operation of the barrier 8 is shown in FIG. As shown, it is provided near the outer surface of the stationary ring 2.
[0027]
The locking member 6 is a long plate member, and the front portion is bent in a crank shape, and the vertical width thereof is the first when the conduction pins 16 and 17 are at the position B in FIG. The distance between the side portions of the first movable lever 14 and the second movable lever 15 is substantially the same, and if the front end portion 6a enters between the levers 14 and 15, they can be prevented from approaching each other. It has become.
[0028]
The lock member 6 is formed with an L-shaped locking portion 6b, and one end of a spring 7 is hung on the locking portion 6b. The other end of the spring 7 is hooked on a locking pin (not shown) of the camera body 1, whereby the lock member 6 is urged forward by the spring 7.
[0029]
At the rear end of the lock member 6, an abutting portion 6 c that is bent toward the lens barrel 3 side is formed, and the abutting portion 6 c is stored in the camera body 1. In some cases, the rear end of the movable ring 5 of the lens barrel 3 is brought into contact. As a result, the lock member 6 is fixed at a position retracted from between the levers 14 and 15 against the biasing force of the spring 7. Further, when the lens barrel 3 is extended from the camera body 1 and the movable ring 5 moves forward, the lock member 6 is prevented from moving forward, so that it is moved forward by the biasing force of the spring 7, It enters between the levers 14 and 15 and comes into contact with the cover 30 to stop (state of FIG. 6B).
Again, when the lens barrel 3 is stored in the camera body 1, the lock member 6 is pressed against the urging force of the spring 7 against the urging force of the spring 7 with the contact portion 6 c being contacted by the rear end of the moving ring 5. And return to the original position.
[0030]
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 force in the right direction to open the barrier 8 from the state of FIGS. 1 and 5, the conduction pins 16 and 17 come into contact with the protrusions 10 a and 10 a and feel a little resistance. However, when further force is applied, the levers 14 and 15 move up and down in a direction away from each other, and the conduction pins 16 and 17 get over the protrusions 10a and 10a. At this time, the user feels as if the operation of the barrier 8 is lightened by being released from the resistance.
Once the conducting pins 16 and 17 exceed the protrusions 10a and 10a, the conducting pins 16 and 17 naturally move up and down in the direction approaching each other along the guide grooves 11 and 11 by the biasing force of the lever spring 18. The barrier 8 naturally moves to the right.
Furthermore, if the user lightly pushes the barrier 8 in the right direction, 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.
[0031]
When the positions of the conductive pins 16 and 17 reach the position of A in FIG. 4, the guide grooves 11 and 11 are separated from each other. Therefore, the user needs a little force to resist the biasing force of the lever spring 18. Then, the conducting pins 16 and 17 move away from each other, and the barrier 8 slides further to the right.
When the conduction pins 16 and 17 reach the corners 10b and 10b of the protrusions 10 and 10, they contact the metal pieces 12b and 12b. At this time, the main switch is connected via the first movable lever 14 and the second movable lever 15. Is turned ON, the drive motor is operated, and the lens barrel 3 is fed out from 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 6a enters between the first movable lever 14 and the second movable lever 15 (FIG. 6B). .
Since the tips of the ridges 10 and 10 are inclined to the right, the levers 14 and 15 are easily moved by the urging force of the lever spring 18 when the barrier 8 is lightly pushed to the right. The metal pieces 12b and 12b are further pushed while exceeding the corners 10b and 10b, and when the metal pieces 12b and 12b come into contact with a part 9a of the protrusion 9, the barrier 8 stops and reaches the open position, FIG. It becomes the state of.
[0032]
(2) When returning the barrier to the closed position
When the user applies a leftward force to the barrier 8 to close the barrier 8 from the state of FIG. 2, the conduction pins 16 and 17 return to the position of C in FIG. At this time, the user applies a force so that the first movable lever 14 and the second movable lever 15 are separated from the urging force of the lever spring 18, and thus feels a little resistance, but reaches the position C. For example, since the shape of the guide grooves 11 and 11 is such that the levers 14 and 15 approach each other, the urging force of the lever spring 18 can be used, and the user is released from the sense of resistance.
When the conduction pins 16 and 17 start to descend from the C position, the conduction pins 16 and 17 are separated from the metal pieces 12b and 12b, thereby turning off the main switch.
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 moves leftward by the urging force of the lever spring 18, but when the conduction pins 16 and 17 reach the B position, the lock member 6 prevents the first movable lever 14 and the second movable lever 15 from approaching. In the meantime, the lens barrel 3 is retracted, and at the same time, the lock member 6 is also pushed by the moving ring 5 and moves backward, and from between the first movable lever 14 and the second movable lever 15. If it is disengaged, it moves to the left by the biasing force of the lever spring 18. Furthermore, when the user pushes lightly in the left direction, the barrier 8 slides while the conduction pins 16 and 17 move relatively along the guide grooves 11 and 11.
When the barrier 8 approaches the closed position, the guide grooves 11 and 11 are shaped so as to be separated from each other. Therefore, when the user applies a force against the urging force of the lever spring 18, the barrier 8 is further leftward. Move to. When the pins 16 and 17 exceed the protrusions 10a and 10a, the user is released from the resistance by the biasing force of the lever spring 18, the conduction pins 16 and 17 return to their original positions, and the barrier 8 is in the state shown in FIG.
[0033]
According to the above camera, when the barrier 8 moves, the lens barrel 3 is also moved out of the camera body 1 with the lock member 6 and stored in the opposite direction. If only opening and closing 3 is performed, the lens barrel 3 and the lock member 6 that prevents the movement of the barrier 8 can be driven, so that the operation is simplified.
Further, since the direction of movement of the barrier 8 is guided using the conductive pins 16 and 17 and the grooves 11 and 11 formed in the barrier 8 itself, the operation of the barrier 8 becomes smooth.
[0034]
Further, when the user tries to manually move the barrier 8 from the closed position toward the open position, first, the first movable lever 14 and the second movable lever 15 should be moved away from each other. The user must apply a force against the urging force of the lever spring 18 and feels a little resistance. However, after that, since the urging force of the lever spring 18 can be used, the user is released from the sense of resistance. Similarly, when the barrier 8 reaches the nearly open position, the user feels resistance and is then released from that resistance. The same applies when the barrier 8 is moved from the open position to the closed position.
Therefore, when the barrier 8 is operated, unless the conscious force against the lever spring 18 is applied, the barrier 8 does not start to move, and the resistance is released after feeling a little resistance at the end of the movement. Therefore, it can be realized that the closed or open position has been reached. Therefore, it is possible to satisfy the user's actual feeling that the user is operating while confirming the state of the camera.
Further, when viewed from the camera side, a force against the lever spring 18 is required at the beginning and end of movement, so that the barrier 8 is not easily opened and closed, and the photographing lens may be damaged by carelessness. Never do.
[0035]
In addition, while the lens barrel 3 is extended, the barrier 8 is indirectly prevented from moving via the conduction pins 16 and 17 of the camera body 1, and the lens barrel 3 is damaged by the barrier 8. Can be prevented.
[0036]
In the above embodiment, the size, shape, etc. of each part of the camera can be changed as appropriate, and it is needless to say that the specific detailed structure is also arbitrary.
For example, the barrier is slid from the front surface of the lens barrel by sliding, but may be configured to rotate, and the lock member may operate the first movable lever and the second movable lever. Although it was configured to prevent the operation of the barrier by blocking, it may be configured to block the operation of the barrier directly.
[0037]
【The invention's effect】
According to the first aspect of the present invention, when the barrier moves, the lens barrel is also drawn out from the camera body or retracted accordingly, so that the user only has to open and close the barrier. Becomes easier.
[0038]
  Also,Claim1According to the invention described in,Since the direction of movement of the barrier is guided using the second conductive portion and the guide portion formed in the barrier itself, the operation of the barrier becomes even smoother.
[0039]
  Furthermore,Claim1According to the invention described in,During the operation of the barrier, unless the user applies a conscious force against the urging member, the barrier does not move, and a little resistance is felt at the end of the movement, and then the resistance is felt. Since the user can actually feel that the camera has been released and has reached the closed or open position, it is possible to satisfy the user's feeling that the camera is operating while grasping the state of the camera.
[0040]
  Claim2According to the invention described in claim1In addition to the effects of the invention described above, the blocking member can prevent the movement of the barrier from being locked when the lens barrel is extended and prevent the lens barrel from being damaged by the barrier.

When separated from the state, the lens barrel is housed in the camera body by the drive source, and the first conducting portion and the second conducting portion are configured such that the barrier is moved from the closed position to the open position. When moving, the barrier comes into contact when it almost reaches the open position, and when the barrier moves from the open position to the closed position, the barrier moves slightly from the open position to the closed position. when it moved to the side, a configuration of separating ,
The second conducting portion includes a pair of conducting members, and the pair of conducting members are urged by a urging member so as to approach each other, and the first conducting portion is the pair of conducting members. The barrier is formed along the direction of movement of the barrier, and is provided with two rows of guide paths for guiding the pair of conducting portions, The two rows of guide paths are arranged such that the pair of conducting members are separated from each other at the beginning and end of movement of the barrier between the open position and the closed position, and then approach each other. A camera characterized by a shape that must work . When the barrier moves from the open position to the closed position, when the pair of conducting members move away from each other and then begin to approach each other, the first conducting portion and the pair of conducting members are separated. The conducting member is separated, and the blocking member is in a position where the pair of conducting members can be prevented from approaching immediately after being separated from the first conducting portion, and the lens barrel is stored in the camera body. The camera according to claim 1 , wherein the camera moves to a position that does not prevent the pair of conducting members from approaching.
