The elastic member 1081 is in contact with the boss portion 1080a and the biasing portion 1081a regardless of whether the anti-theft switch 1080 is in the "enabled" or "disabled" position. When the anti-theft switch 1080 is at the "effective" position, the biasing portion 1081a biases the boss portion 1080a forward/+Z direction, and when the anti-theft switch 1080 is at the "disabled" position, the biasing portion 1081a biases the boss portion 1080a in the -Z direction.

FIG. 13(a) shows the positional relationship between the second bolt mechanism 1400 and the front sub cover 1040 when the anti-theft switch 1080 is in the "disabled" position. The state of FIG. 13(a) corresponds to the initial state of S1 of FIG. The holding member 1402 moves rearward/−Z direction, the end face 1402c1 of the elongated hole 1402c abuts against the protrusion 1401e, and the second bolt member 1401 moves rearward/−Z direction to engage the second engaging member. Joint portion 1401a and front sub cover 1040 are not in contact with each other.

FIG. 13(b) shows the positional relationship between the second bolt mechanism 1400 and the front sub-cover 1040 when the anti-theft switch 1080 is in the "effective" position. The state of FIG. 13(b) corresponds to the states from S2 to S4 of FIG. The holding member 1402 moves forward/+Z direction, and the end face 1402c1 of the long hole 1402c also moves forward/+Z direction, but the front sub-cover 1040 is in the first position shown in FIGS. 9(a) and 10(a). (initial state of S1 in FIG. 14). Therefore, the second engaging portion 1401a contacts the end surface 1045a of the cylindrical portion 1046 of the front sub cover 1040 before the protrusion 1401e contacts the end surface 1402c1 of the long hole 1402c.

FIG. 13(c) shows the positional relationship between the second bolt mechanism 1400 and the front sub-cover 1040 when the front sub-cover 1040 is rotated counterclockwise by .theta..degree. from the state shown in FIG. 13(b). The state of FIG. 13(c) corresponds to the state in which the anti-theft function is set in S6 of FIG. The second engaging portion 1401 a is pushed forward/+Z direction by the spring force of the compression coil spring 1403 and engages with the second notch portion 1045 of the front sub cover 1040 .

<Releasing the anti-theft function>
FIG. 13(c) shows the first cutout portion 1044 of the front sub-cover 1040 and the first bolt member 1303 when the fixing device 800 is removed from the state in which the anti-theft function is set in S6 of FIG. It shows the positional relationship of the engaging portion 1303d.

When the screw portion 801 of the fixing device 800 is pulled out from the screw hole 1072, the first bolt member 1303 is urged upward/-Y direction by the compression coil spring 1306, but the front sub-cover 1040 is in the state shown in FIG. 13(c). It remains in the second position. Therefore, the positions of the first cutout portion 1044 and the second engaging portion 1303d do not match, and the end portion of the first engaging portion 1303d contacts the inner diameter portion of the cylindrical portion 1046 of the front sub cover 1040. and stops while being urged downward/-Y direction.

When the anti-theft switch 1080 is switched to the "disabled" position from this state, the second bolt member 1401 retreats rearward/-Z direction from the state of FIG. 13(c). Then, the second engaging portion 1401a is separated from the second cutout portion 1045 of the front sub-cover 1040 and the engagement is released.

From this state, when the front sub cover 1040 is rotated clockwise by θ° (from the second position to the first position), the spring force of the compression coil spring 1306 pushes the first engagement portion 1303 d to the first notch portion 1044 . , the initial state of S1 in FIGS. 10(a) and 14 is reached.

According to this embodiment, for example, when shooting at a stadium or a concert venue where an unspecified number of people are present, the user leaves the scene while leaving the camera 1000 attached with the fixing device 800 such as a tripod or pan head. In this case, the anti-theft effect of the lens unit 900 can be improved. In such a case, the anti-theft switch 1080 is "enabled", the fixing device 800 is attached to the camera 1000, and the front sub-cover 1040 is rotated counterclockwise by θ° (to the second position). You can set the prevention function.
In order to remove the lens unit 900 from the camera main body 1001 in this state, the fixing device 800 is first removed from the camera main body 1001 . Furthermore, it is necessary to "disable" the anti-theft switch 1080 and rotate the front sub-cover 1040 clockwise θ° (to the first position). Therefore, it is possible to prevent a third party from taking out the lens unit 900 from the camera 1000 when the user is absent.

Also, even if the user accidentally activates the anti-theft switch 1080, the front sub-cover 1040 can be rotated counterclockwise by θ° (to the second position) unless the fixing device 800 is attached. , the possibility of erroneous operation is also reduced.

Various changes and modifications can be made to the present embodiment without departing from the gist of the present invention.

The bolt mechanism of the present embodiment uses a spring force, but is not limited to this, and detects the attachment of a fixture or the position of an anti-theft switch, and operates the bolt mechanism using the power of a motor or the like. You may let

Further, in this embodiment, by rotating the front sub-cover 1040, even if the lens release button 1050 is pressed, the engagement of the lock pin 1020 is not released. On the other hand, the engagement of the lock pin may be prevented by moving only the lens release button 1050 .

Further, a switch (not shown) detects that the front sub cover 1040 is in the second position, and at that time, a special operation such as a long press of a specific button is performed, so that at least a part of the camera 1000 is turned on. It is also possible to disable the operation buttons. By doing so, it is possible to prevent a third party from arbitrarily changing the settings or operations while the user is away from the place where the camera 1000 is placed. Further, if remote control of the camera 1000 is enabled using a wireless function (not shown), multiple cameras can be independently remotely controlled in a large area such as a stadium while being anti-theft.

[Embodiment 2] Next, Embodiment 2 will be described.

In the second embodiment, the same reference numerals are assigned to the same configurations as in the first embodiment, and the corresponding or different configurations are assigned reference numerals in the 2000s.

An imaging apparatus 2000 of this embodiment is a lens-interchangeable camera, as in the first embodiment.

FIG. 15(a) is a perspective view showing a simplified configuration of the imaging apparatus 2000 of Embodiment 2 with the front part 2002 facing upward, and FIG. 15(b) is a P2 portion of FIG. It is an enlarged view. FIG. 15 shows the configuration of a front surface portion 2002 and a bottom surface portion 2005 of a camera main body portion 2001 that constitutes the housing of the camera 2000 .

The lens unit 900 is attached by rotating the camera-side mount section 2010 relative to the lens-side mount section 901, as in the first embodiment. The lock pin 2020 engages with the lens unit 900 attached to the lens side mount section 901 to prevent rotation. The lock lever 2050 has an anti-theft function that disables the operation of a lens release button 2051, which will be described later.

The lock pin 2020 is interlocked with the lens release button 2051, and when the lens release button 2051 is pushed, the lock pin 2020 is disengaged from the lens unit 900. As shown in FIG. The user can remove the lens unit 900 from the camera body 2001 by rotating the lens unit 900 while pressing the lens release button 2051 . The operation of attaching and fixing the lens unit 900 to the camera body 2001 and the operation of releasing the lock pin 2020 by using the lens release button 2051 to remove the lens unit 900 are the same as in the first embodiment.

A bottom surface portion 2005 of the camera main body portion 2001 is provided with a device mounting portion 2070 for mounting a tripod or a pan head, and an anti-theft switch 2080 . The device mounting portion 2070 has a screw hole 2070a into which a threaded portion of a fixing device is screwed, and a detent hole 2070b into which a protrusion provided on the fixing device is inserted to prevent rotation of the fixing device.

The anti-theft switch 2080 is an operating member that permits or restricts rotation of a lock lever 2050 to a second position (a position where the lens lock state cannot be released), which will be described later.

Next, the configuration of the lock lever 2050 of this embodiment will be described with reference to FIG. 15(b).

A lock lever 2050 is a rotary operation member having a lens release button 2051 . The lens release button 2051 moves the lock pin 2020 from the lens locked state to the unlocked state. The lens release button 2051 is set to a state in which operation of the lens release button 2051 is permitted and a state in which the lens release button 2051 cannot be operated, depending on the rotational position of the lock lever 2051 .

The lock lever 2050 has a disc-shaped lever body portion 2052A, a first lever portion 2052B extending in opposite directions from the lever body portion 2052A, and a second lever portion 2052C. A lock claw 2053 is rotatably supported by a hinge portion 2055 at the end of the second lever portion 2052C. The lock claw 2053 is supported so as to allow rotation in the direction r1 with respect to the second lever portion 2052C, but prohibit rotation in the direction r2 opposite to r1. In addition, the lock claw 2053 is constantly urged by the plate spring 2054 so that it returns in the direction r2 when rotated in the direction r1.

Anti-theft switch 2080 has a slider 2081 and restricts or releases rotation of lock lever 2050 to the second position. The slider 2081 is slidably accommodated in a notch portion 2084 of the bottom portion 2005 . The notch portion 2084 is a rectangular groove formed adjacent to the boundary between the camera body portion 2001 and the front portion 2002 in which the lock lever 2050 is arranged. The slider 2081 is provided with a slide lock button 2082 substantially in the center in the longitudinal direction, and the slider 2081 can be slid by pressing the slide lock button 2082 . A slide lever portion 2083 is provided on the slider 2081 , and the slide lever portion 2083 moves in conjunction with the slider 2081 to restrict or allow rotation of the lock lever 2050 .

When the lock lever 2050 is rotated to a second position, which will be described later, the lens release button 2051 cannot be operated, and the lens unit 900 cannot be removed. Further, the slider 2081 cannot be slid unless the slide lock button 2082 is pressed. A specific configuration is described, for example, in Japanese Unexamined Patent Application Publication No. 2004-119282. However, in the present embodiment, the slider 2081 is locked so as not to be slidable at both ends (valid position and invalid position) of the movable range.

Next, referring to FIG. 16, the operation of setting or canceling the anti-theft function with the lock lever 2050 of this embodiment will be described.

FIG. 16(a) is a view of the P2 portion viewed from the front portion 2002 with the fixture 800 attached to the bottom portion 2005 of the camera body portion 2001, and shows the operation for setting the anti-theft function. . FIG. 16(b) shows the operation when the fixing device 800 is removed from the camera body 2001 and the anti-theft function of FIG. 16(a) is released. 16 are denoted by the same reference numerals as in FIG. 15, except for the fixing device 800. FIG.

In FIG. 16(a), first, the slider 2081 is slid to the effective position, and the slide lever portion 2083 is moved to position t6. It is configured such that the lens release button 2051 can be pushed when the lock lever 2050 is at the position t3. When the lock lever 2050 is rotated from the position t2 to the position t1 in the direction t4, the lock claw 2053 rotates and bends in the direction r1 about the hinge portion 2055 while contacting the fixing device 800. Thus, lock lever 2050 can be rotated to position t1. Then, when the lock lever 2050 reaches the position t1, it is no longer in contact with the fixture 800, and the lock claw 2053 returns to a state in which it is aligned with the second lever portion 2052C by the biasing force of the plate spring 2054. FIG. Even if an attempt is made to rotate the lock lever 2050 in the direction t5 opposite to t4 from this state, the lock claw 2053 cannot bend and rotate while in contact with the fixture 800, resulting in a locked state. Note that when the lock lever 2050 is at the position t1, the mechanism inside the lock lever 2050 disables the operation of the lens release button 2051 and prevents the lens unit from being removed.

Next, the fixing device 800 is removed from the camera body 2001 from the state shown in FIG. 16(a), and the slider 2081 is slid from the effective position to the ineffective position in the direction t7 as shown in FIG. 16(b). 2083 is moved to position t8. In this case, the slide lever portion 2083 pushes the second lever portion 2052C of the lock lever 2050 to rotate the lock lever 2050 in the direction of t5. When the fixing device 800 is not attached, the lock claw 2053 does not contact the fixing device 800 while the lock lever 2050 rotates from position t1 to position t3. As a result, the lock lever 2050 becomes rotatable in the direction of t5 and is fixed at the position t3. In addition, since the slider 2081 is locked at the invalid position, the lock lever 2050 is prevented from accidentally moving.

Next, referring to FIG. 19, the procedure for setting the anti-theft function of the second and third embodiments will be described.

In S21, the anti-theft switch 2080 is slid to the effective position to enable the setting of the anti-theft function. In this embodiment, when the anti-theft switch 2080 (slider 2081) is slid leftward in FIG. 16B, it is effective, and when it is slid rightward, it is ineffective. If it is valid, the process proceeds to S22, and if it is invalid, the lens can be attached and detached in S27, and the lens release button 2051 can be pressed.

In S22, the fixing device 800 is attached to the device mounting portion 2070 of the bottom surface portion 2005 of the camera body portion 2001. FIG. If the fixing device 800 is attached in S22, the process proceeds to S23, and if the fixing device 800 is not attached, the lens becomes detachable in S27.

In S23, the lens unit 900 is attached to the camera body 2001 and the camera 2000 is set. In this state, since the lock lever 2051 has not yet been rotated to the second position, the lens unit 900 can be removed from the camera body 2001 and replaced by pressing the lens release button 2051 .

By rotating the lock lever 2050 to the second position in S24, the anti-theft function is set in S25. In FIG. 16(a), the anti-theft function is set by rotating the lock lever 2050 from position t3 to position t1. When the anti-theft function is set in S25, the lens release button 2051 cannot be pressed. Also, if the lock levers 2050 and 2150 are not rotated from the position t3 to the position t1 in S24, the lens release button 2051 can be pushed in S27 and the lens can be attached/detached.

In S26, when the fixing device 800 is removed from the camera main body 2001 and the anti-theft switch 2080 on the bottom surface 2005 is set to the disabled position, the lens can be attached/detached. Also, if the anti-theft switch 2080 remains in the effective position, the anti-theft state is maintained.

In this embodiment, even when the anti-theft function is enabled by the anti-theft switch 2080 and the fixing device 800 is attached to the camera body 2001, the lens unit 100 can be locked when the lock lever 2050 is not rotated to the second position. can be attached and detached. Then, by rotating the lock lever 2050 to the second position, the anti-theft state is set in which the lens release button 2051 cannot be pushed, and the operation of the lens release button 2051 is disabled.

Also, when canceling the setting of the anti-theft function, it is necessary to remove the fixing device 800 from the camera body 2001 and set the anti-theft switch 2080 to the disabled position. Therefore, it is possible to prevent a third party from taking out the lens from the camera when the user is absent.

[Embodiment 3] Next, Embodiment 3 will be described.

When the cover portion 3052 of the lock lever 3050 is moved to the closed position (t21) from this state, the connecting member 3054 pushes the first link member 3301 clockwise at t23, and the first link member 3301 rotates clockwise. . The first link member 3301 moves along the guide surface 3309a of the lock member 3309 and eventually engages with the stepped surface 3309b. As a result, the first link member 3301 is locked by the step surface 3309b so that it cannot rotate counterclockwise, and the cover portion 3052 of the lock lever 3050 cannot move from the closed position (t21) to the open position (t22) ( after setting up the anti-theft function). In the anti-theft state, unless the anti-theft switch 2080 is switched to the disabled position, the cover portion 3052 of the lock lever 3050 cannot be opened (t22) and the lens release button 3051 cannot be operated. It cannot be removed.

To cancel the setting of the anti-theft function, that is, to allow the cover portion 3052 of the lock lever 3050 to move to the open position (t22), the slider 2081 of the anti-theft switch 2080 is slid to the disabled position (t26). When the slider 2081 of the anti-theft switch 2080 is at the disabled position (t26), the lock member 3309 is pushed down in the direction of t25 against the spring force of the compression coil spring 3313 in the direction of t28 and is held at the dotted line position. Therefore, the first link member 3301 is separated from the stepped surface 3309b of the lock member 3309, and the lock is released. In this state, the first link member 3301 is pulled by the spring force of the tension coil spring 3306 in the direction of t31 and rotates counterclockwise at t23, thereby moving the cover portion 3052 of the lock lever 3050 to the open position (t22). do. When the anti-theft function is released, the cover portion 3052 of the lock lever 3050 is at the open position (t22) and the lens release button 3051 can be pushed, so that the lens unit 900 can be removed.

When the lens release button 3051 is pushed in the direction of t29, the lock pin 3020 sinks in the direction of t30 through the arm portion 3021, and the lens unit 900 can be removed.

Next, referring to FIG. 22, a procedure for setting or canceling the anti-theft function using the lock lever 3050 of this embodiment will be described.

S31 to S33 and S35 to S37 of FIG. 22 are the same as S21 to S23 and S25 to S27 of FIG. 19, and only S34 is different.

In S34, the anti-theft function is set by moving the cover portion 3052 of the lock lever 3050 to the closed position (t21).

In this embodiment, even when the anti-theft switch 3050 is set to the effective position (t27) and the fixture 800 is attached to the bottom surface 3005 of the camera 3000, the lock lever 3050 is not moved to the closed position (t21). The lens unit can be attached and detached. After that, by setting the cover portion 3052 of the lock lever 3050 to the closed position (t21), the lens release button 3051 cannot be operated, and the anti-theft function can be set. In order to cancel the anti-theft function, it is necessary to remove the fixing device 800 from the camera body 3001 and set the anti-theft switch 3080 to the disabled position (t26). Therefore, it is possible to prevent a third person from taking out the lens from the camera when the user is absent.
