  ADVANTAGE OF THE INVENTION According to this invention, the camera which can close a mount opening reliably at the time of attachment or detachment of the accessory for cameras can be provided.

Hereinafter, an embodiment of a camera to which the present invention is applied will be described with reference to the drawings.
FIG. 1 is a perspective view illustrating the structure of the camera of the embodiment.
In order to facilitate understanding, a three-dimensional coordinate system composed of an X axis, a Y axis, and a Z axis is set in each drawing.
The camera 1 of the embodiment is an interchangeable lens camera body to which an interchangeable lens barrel 2 is detachably mounted.
The camera 1 includes a housing 10 formed in a substantially rectangular parallelepiped box shape and a camera-side mount 20 formed on a front surface portion of the housing. The front surface portion of the housing 10 means a surface portion that faces the subject at the time of shooting.
A mark (index) 12 is provided on the front surface of the housing 10 as a mounting index when the lens barrel is mounted. The lens barrel 2 is also provided with a mark (index) 122 corresponding to the index 12.

The camera-side mount 20 is a part to which the interchangeable lens barrel 2 is detachably attached, and constitutes a mount system (fastening mechanism) in cooperation with the barrel-side mount 120 provided in the interchangeable lens barrel 2. ing. The interchangeable lens barrel 2 shown in each drawing including FIG. 1 is an example of a camera accessory that can be attached to the camera 1, and the camera 1 has a mount having substantially the same configuration as the interchangeable lens barrel 2. Other interchangeable lens barrels and other accessories equipped with a mechanism can be selectively mounted.
The camera-side mount 20 is a bayonet-type mounting mechanism, and a plurality (for example, three in this embodiment) of claw portions 21 mechanically engage with claw portions 121 provided on the lens barrel-side mount 120. This restricts the relative movement of the camera 1 and the interchangeable lens barrel 2 in the optical axis direction.

Here, the camera-side mount 20 of the present embodiment is an electric bayonet mount. When the interchangeable lens barrel 2 is mounted, the above-described claw portion is driven by the driving force of the electric motor 60 (see FIG. 2). 21 and 121 are mechanically engaged with each other.
FIG. 2 is an exploded perspective view showing the structure of the camera-side mount provided in the camera shown in FIG.
FIG. 3 is a block diagram showing the configuration of the camera shown in FIG.
The camera-side mount 20 includes a front decoration ring 30, a mount opening defining portion 40, an engagement ring 50, an electric motor 60, a drive member 70, a control portion 80, and the like (see FIG. 3 for the control portion 80).
The front decoration ring 30 is a member formed in an annular shape, and is fixed to the peripheral edge of the circular opening 11 formed on the front surface of the housing 10. Subject light traveling from the interchangeable lens barrel 2 passes through the inner diameter side of the front ring 30 and is guided to an image sensor 83 (see FIG. 3) provided in the housing 10 of the camera 1.

The mount opening defining portion 40 is a disk-like member in which a mount opening 41 that is a circular opening is formed at the center, and is disposed closer to the imaging element 83 than the front decoration ring 30. The mount opening defining portion 40 includes a plurality of electrical contacts 42 on a surface portion facing the subject side in the optical axis direction. These electrical contacts 42 are provided so as to be in contact with electrical contacts (not shown) provided in the interchangeable lens barrel 2 in a state where the interchangeable lens barrel 2 is mounted on the camera 1.
The camera 1 uses these electrical contacts 42 to supply power to the interchangeable lens barrel 2 or to perform electrical communication with the interchangeable lens barrel 2, for example. Further, the control unit 80, which will be described later, contacts the electrical contacts with each other so that the lens barrel side mount 120 of the interchangeable lens barrel 2 is inserted into the inner diameter side of the engagement ring 50 and is disposed at a predetermined fastening position. It is detected that

The engagement ring 50 is a member disposed between the front decoration ring 30 and the mount opening defining portion 40, and a main body 51 formed in an annular shape, and an outer diameter side from the outer peripheral edge of the main body 51. And a drive lever 52 provided so as to protrude.
The main body 51 includes a claw portion 21 that protrudes from the inner peripheral edge portion toward the inner diameter side. For example, three claw portions 21 are formed at substantially equal intervals.
The drive lever 52 includes a drive groove 53 into which a protrusion 71 formed on a drive member 70 described later is inserted, and the main body 51 transmits the output of the electric motor 60 to the drive lever 52. It is supported by the housing 10 so as to rotate around the optical axis A in a plane orthogonal to the optical axis A.

The electric motor 60 is an actuator that rotates the engagement ring 50 in the forward direction and the reverse direction. For example, a stepping motor or the like is used. A pinion gear 61 is attached to the output shaft of the electric motor 60. The electric motor 60 is driven and controlled by the control unit 80 (see FIG. 3).
The drive member 70 is a disk-shaped member that transmits the output of the electric motor 60 to the engagement ring 50. The drive member 70 has a gear 72 that meshes with the pinion gear 61 described above formed on the outer peripheral edge thereof. When the electric motor 60 is operated, the drive member 70 is rotated around the shaft portion 73 that extends substantially parallel to the optical axis A accordingly. Rotate.

The drive member 70 includes a pin-like protrusion 71 provided so as to protrude from the surface facing the subject side in the optical axis direction toward the subject side in the optical axis direction. As described above, the protrusion 71 is inserted into the drive groove 53 provided in the drive lever 52.
The drive groove 53 is a linear region 53 a formed in a straight line extending in a direction parallel to the radial direction of the main body 51, and a shaft portion that is formed continuously with the linear region 53 a and supports the drive member 70. Arc region 53b formed in parallel with the arc centered at 73. The linear region 53 a is formed on the proximal end side of the drive lever 52, and the arc region 53 b is formed on the distal end side of the drive lever 52.

  The control unit 80 converts the electrical contact 42, the electric motor 60, the interchangeable lens barrel 2 described above from the camera 1, the removal button 81 that is operated, the camera 1 power switch 82, and the subject light into electrical signals. Electrically connected to an imaging device 83 to output, a display device 84 that displays an image formed based on the output of the imaging device 83, a drive device 85 (see FIG. 3) that records image data in a removable memory, and the like And control them centrally. The removal button 81 is provided on the front surface of the housing 10 as shown in FIG.

Next, the operation of the camera side mount 20 will be described.
FIG. 4 is a diagram showing the operation of the camera side mount shown in FIG.
4A shows an initial state before the interchangeable lens barrel 2 is mounted, and FIG. 4B shows a state where the camera-side mount 20 and the barrel-side mount 120 are completely fastened. c) shows a state in which the mount barrier described later is in the open position.
As shown in FIG. 4A, in the initial state, the protrusion 71 of the drive member 70 is inserted into the linear region 53a in the drive groove 53 formed in the drive lever 52. When the lens barrel side mount 120 of the interchangeable lens barrel 2 is inserted into the inner diameter side of the main body 51 of the engagement ring 50, the control unit 80 detects this using a part of the electrical contact 42, The electric motor 60 is rotated. Hereinafter, the rotation direction of the electric motor 60 at this time will be described as an attachment direction.

The drive member 70 rotates around the shaft portion 73 when the output of the electric motor 60 is transmitted (see FIG. 4B). While the drive member 70 rotates, the user of the camera 1 needs to hold the interchangeable lens barrel 2, but does not need to rotate the interchangeable lens barrel 2 with respect to the camera 1.
When the driving member 70 rotates, the protrusion 71 presses the inner surface of the driving groove 53 while moving in the linear region 53 a of the driving groove 53. As a result, the main body 51 of the engagement ring 50 rotates around the optical axis, and the latch pin 43 (see FIG. 1) provided in the mount opening defining portion 40 is a hole (not shown) formed in the lens barrel side mount 120. The camera 1 and the interchangeable lens barrel 2 are fastened. The rotation angle of the engagement ring 50 at this time is not particularly limited, and may be appropriately set according to the number of the claw portions 21 and the like. Since the engagement ring 50 of the present embodiment includes the three claw portions 21, the rotation angle of the main body 51 is preferably about 45 ° to 60 °, for example.

  In the fastening completion state shown in FIG. 4B, circumferential positions around the optical axis of the claw portion 21 of the camera side mount 20 and the claw portion 121 (not shown in FIG. 4) of the lens barrel side mount 120. This limits the relative movement of the camera 1 and the interchangeable lens barrel 2 in the optical axis direction. The relative movement in the radial direction between the camera 1 and the interchangeable lens barrel 2 is performed by a groove 44 (see FIG. 1) provided in the mount opening defining portion 40 and a not-shown projection provided in the interchangeable lens barrel 2. Are mechanically (structurally) limited by fitting. When the interchangeable lens barrel 2 is removed from the camera 1, the engagement ring 50 is rotated in the direction opposite to the mounting direction.

Further, the camera 1 of the present embodiment includes a mount barrier 90.
The mount barrier 90 substantially closes the mount opening 41 formed in the mount opening defining portion 40 described above, for example, when the interchangeable lens barrel 2 is not attached to the camera 1.
As shown in FIG. 2, the mount barrier 90 includes a main body 91 formed in a disk shape, a drive lever 92 provided to protrude from the outer peripheral edge of the main body 91 to the outer diameter side, and the mount barrier 90. A biasing spring 93 that biases to a closed position described later is provided. The drive lever 92 is formed in a substantially L shape in plan view, and is rotatably supported by the shaft portion 94 at the bent portion. The biasing spring 93 is a tension coil spring having one end fixed to the housing 10 and the other end fixed to the drive lever 92.
The mount barrier 90 rotates around the shaft portion 94 to move between a closed position where the main body portion 91 closes the mount opening 41 and an open position where the main body portion 91 opens the mount opening 41.

The mount barrier 90 is disposed on the back surface (surface facing the photographer side in the optical axis direction) side of the mount opening defining portion 40, and is in a state where the interchangeable lens barrel 2 is mounted on the camera side mount 20. Is also movable between a closed position and an open position.
In the initial state shown in FIG. 4A, the mount barrier 90 is disposed at the closed position. The tip of the drive lever 92 is disposed on the movement locus of the protrusion 71 when the drive member 70 rotates, but is not in contact with the protrusion 71.

  As shown in FIG. 4B, in the fastening completion state in which the engagement ring 50 is rotated to mount the interchangeable lens barrel 2 on the camera 1, the protrusion 71 and the drive lever 92 are in contact with each other. The position of 90 does not change. In the fastening completion state shown in FIG. 4B, it is not necessary to drive the mount barrier 90, so that the protrusion 71 and the drive lever 92 do not need to contact each other.

When the electric motor 60 is further rotated in the mounting direction in the fastening completion state shown in FIG. 4B, the drive member 70 rotates in the same direction as the direction when the interchangeable lens barrel 2 is mounted. The protrusion 71 provided on the drive member 70 presses the drive lever 92 accordingly. Thus, the mount barrier 90 rotates around the shaft portion 94 against the urging force of the urging spring 93, and the main body portion 91 retracts from the optical path of the subject light to open the mount opening.
At this time, the protrusion 71 of the drive member 70 moves within the arc region 53b in the drive groove 53 of the drive lever 52 provided on the engagement ring 50, and therefore the drive force from the drive member is applied to the engagement ring 50. Is not transmitted, and the engagement ring 50 does not rotate.

When driving the mount barrier 90 from the open position to the closed position, the electric motor 60 may be rotated in the direction opposite to the mounting direction. The protrusion 71 moves in the arc region 53b, and the drive lever 92 automatically returns to the closed position by the biasing force of the biasing spring 93.
As described above, in the camera 1 of the present embodiment, the protrusion 71 of the driving member 70 drives both the engagement ring 50 and the mount barrier 90 provided with the claw portion 21. The rotational drive and the opening / closing drive of the mount barrier 90 can be performed separately.

Next, drive control of the camera side mount 20 and the mount barrier 90 performed by the control unit 80 provided in the camera 1 of the present embodiment when the interchangeable lens 2 is attached and removed will be described.
FIG. 5 is a flowchart showing drive control of the camera side mount and the mount barrier performed by the control unit shown in FIG.
Hereinafter, each step will be described.

<With interchangeable lens barrel>
(Step S01: Interchangeable lens barrel fastening)
In an initial state before the interchangeable lens barrel 2 is attached to the camera 1 (see FIG. 4A), the mount barrier 90 is in the closed position, preventing dust and the like from entering the housing 10. .
When a user such as a photographer attaches the interchangeable lens barrel 2 to the camera 1, the user attaches the interchangeable lens barrel 2 to the body of the engagement ring 50 while aligning the index 122 on the interchangeable lens side with the index 12 on the camera side. Insert into the inner diameter side of the part 51. When the control unit 80 detects that the electrical contact 42 contacts the electrical contact of the interchangeable lens barrel 2, the control unit 80 proceeds to step S02 accordingly.

(Step S02: Motor drive)
The control unit 80 controls the electric motor 60 to rotate the drive member 70 in the mounting direction, and proceeds to step S03. The driving amount of the electric motor 60 at this time (stop position of the engagement ring 50) may be controlled by, for example, the number of driving pulses input to the electric motor 60, or (the claw portion 21 is engaged with the claw portion 121). A position detection switch for detecting the position of the drive member 70 or the engagement ring 50 (the number of drive pulses necessary for the control is previously stored in the control unit 80) is provided and controlled based on the output of the detection switch. Also good.
The engagement ring 50 rotates from the initial position (first position) shown in FIG. 4 (a) to the fastening completion position (second position) shown in FIG. 4 (b), whereby the interchangeable lens barrel 2 is rotated. The claw part 21 of the camera side mount 20 and the claw part 121 of the lens barrel side mount 120 can be mechanically engaged without rotating the camera 1 relative to the camera 1. The control unit 80 can detect that the contacts are in contact with each other even when the power switch 82 of the camera 1 is off.

(Step S03: Power switch operation detection)
If the power switch 82 is on when the interchangeable lens barrel 2 is mounted, the control unit 08 proceeds to step S04 and performs the opening control of the mount barrier 90. On the other hand, if the power switch 82 is in the OFF state, the standby state is entered, and the process is terminated while the mount barrier 90 is held in the closed position. If the power switch 82 is turned on with the interchangeable lens barrel 2 attached, the control in step S04 described below is performed to drive the mount barrier 90 to the open position.

(Step S04: Motor drive)
The controller 80 controls the electric motor 60 to rotate it by a predetermined amount in order to open the barrier in the mounting direction, and ends the process. In response to this, the drive member 70 moves from the fastening completion position shown in FIG. 4 (b) to the imageable position (third position) shown in FIG. 4 (c). The mount barrier 90 is driven to move from the closed position to the open position in conjunction with the rotational movement of the drive member 70.

Next, control when removing the interchangeable lens barrel 2 will be described.
<When removing the interchangeable lens barrel>
(Step S11: Detachable button press detection)
When the user presses the detach button 81, the control unit 80 proceeds to step S12 accordingly. When the pressing operation of the removal button 81 is not detected, the standby state is entered.
(Step S12: Mount position determination)
The control unit 80 determines the position of the mount barrier 90. When the mount barrier 90 is in the closed position, dust or the like does not enter the housing 10 even if the interchangeable lens barrel 2 is removed. Therefore, the process proceeds to step S14 and the engagement ring 50 is driven. On the other hand, when the mount barrier 90 is in the open position, the process proceeds to step S13 and the close control of the mount barrier 90 is performed.

(Step S13: Motor drive)
The control unit 80 controls the electric motor 60, drives the mount barrier 90 from the open position to the closed position, and proceeds to step S13. At this time, since the protrusion 71 of the drive member 70 moves within the arc region 53b in the drive groove 53 formed in the drive lever 52 of the engagement ring 50, the engagement ring 50 does not rotate.
(Step S14: Engagement ring rotation)
The control unit 80 controls the electric motor 60 to drive the engagement ring 50 from the fastening completion position shown in FIG. 4B to the initial position shown in FIG. Thus, the protrusion 71 of the drive member 70 is not in contact with the drive lever 92 of the mount barrier 90, but the mount barrier 90 is held in the closed position by the biasing spring 93.

According to the camera 1 of the embodiment described above, the following effects can be obtained.
(1) Since the camera-side mount 20 is an electric mount mechanism that detects the interchangeable lens barrel 2 and automatically performs the mounting operation, the mounting operation is easy. Further, since the mount barrier 90 that closes the mount opening 41 formed in the camera side mount 20 is provided, even when the interchangeable lens barrel 2 is detached from the camera 1, dust or the like enters the inside of the housing 10. Can be prevented. In the camera 1 of the present embodiment, when the interchangeable lens barrel 2 is attached / detached, the mount barrier 90 is always closed, and it is structurally impossible to open the mount opening 41. It is possible to reliably prevent dust and the like from entering.
(2) Since the rotation direction of the drive member 70 (and the electric motor 60) is the same during the transition from the initial state in which the interchangeable lens barrel 2 is not mounted to the state in which the mount opening 41 is opened and the photographing is possible, The interchangeable lens barrel 2 can be quickly shifted from the non-mounted state until it can be photographed. Moreover, the control of the electric motor 60 is easy.
(3) Since the engagement ring 50 and the mount barrier 90 of the camera side mount 20 are driven by a common (single) electric motor 60, space efficiency is good.
