As described above, in the interchangeable lens type camera 10 of the present embodiment, the connector is provided separately for each function of the interchangeable lens, so that the function of the interchangeable lens is added later. However, since it is only necessary to provide a connector corresponding to the new function, the conventional connector can be used as it is. As a result, it is possible to easily improve the function while ensuring compatibility with the conventional one.

Even when the function of the interchangeable lens is added and the number of connectors is increased, the concave portion 60 (so-called escape) is formed in the lens mount 16 on the camera body side so that the added connector does not touch. Since it is formed, the conventional camera body can be used as it is.

As described above, in the interchangeable lens camera 10 of the present embodiment, it is possible to easily add and improve the functions while ensuring compatibility between the interchangeable lens and the camera body.

The case of expanding the function of the interchangeable lens camera 10 will be described below.

First, an AF interchangeable lens 12B having an autofocus function in a system which is initially composed of a manual focus MF interchangeable lens 12A and a manual focus MF compatible camera body 14A, an autofocus function and an auto zoom. AFZ with functions
Interchangeable lens 12C, and AFZ compatible camera body 1 having an auto focus control function and an auto zoom control function
The case of adding 4B will be described (see FIG. 4).

The interchangeable lens 12B for AF is shown in FIGS.
As shown in, an autofocus function is added to the manual focus MF interchangeable lens 12A, and an AF drive unit 70 for autofocusing the photographing lens 20 is provided. Then, in response to the autofocus function, the AF male connector 38D is attached to the connecting portion 18.
Is equipped with.

The AF interchangeable lens 12B includes
An MF / AF switching mechanism 71 for switching the taking lens 20 between manual focus and auto focus is provided so that the user can selectively use it.

As shown in FIGS. 7 and 8, the AFZ interchangeable lens 12C is obtained by further adding a zoom function to the AF interchangeable lens 12B. The zoom lens 72 and the zoom for driving the zoom lens 72 are provided. The drive unit 74 is provided. The connection portion 18 is provided with a zoom male connector 38C corresponding to the zoom function.

The AFZ interchangeable lens 12C is also provided with an MZ / AZ switching mechanism 75 for switching zooming of the zoom lens 72 between manual and automatic, so that the user can selectively use it. ing.

The AFZ compatible camera body 14B is shown in FIGS.
As shown in FIG. 8, an autofocus control function and a zoom control function are added to the manual focus MF compatible camera body 14A. The MPU 52 is a corresponding interchangeable lens 12B for AF or interchangeable lens 12 for AFZ.
When C is mounted on the lens mount 16, the AF interchangeable lens 12B or the AFZ interchangeable lens 12C loads the control program from the ROM 36 incorporated in the lens mount 16 and stores the control program in the incorporated DRAM 52a. Then, the AF driving unit 70 or the zoom driving unit 74 of the AF interchangeable lens 12B or the AFZ interchangeable lens 12C is controlled based on the control program and data stored in the DRAM 52a. An AF female connector 62D and a zoom female connector 62C for transmitting control signals to the AF driving unit 70 and the zoom driving unit 74 are provided in the recess 60 of the lens mount 16.

The AF female connector 62D and the zoom female connector 62C are the male AF connector 38D and the male zoom connector 3 provided on the interchangeable lens 12B for AF and the interchangeable lens 12C for AFZ, respectively.
The interchangeable lens for AF 12 is arranged corresponding to 8C.
When B is mounted on the lens mount 16, the AF male connector 38D provided on the AF interchangeable lens 12B is automatically connected to the AF female connector 62D. In addition, the AFZ compatible camera body 14B is attached to the lens mount 1
When it is mounted on 6, the AF male connector 38D and the zoom male connector 38C provided on the AFZ interchangeable lens 12C are connected to the AF female connector 62D and the zoom female connector 62C.

The AF interchangeable lens 12B and the AFZ interchangeable lens 12C added as described above are additionally provided with male connectors corresponding to the newly added functions.

However, in the interchangeable lens type camera of this embodiment, even if there is no female connector corresponding to the lens mount 16 on the camera body side, the male connector is provided in the recess 60 provided in the lens mount 16. Since the camera body is housed, an interchangeable lens having a new function can be attached even to a camera body that does not support the added function.

For example, as shown in FIG. 9, when an AFZ interchangeable lens 12C having an autofocus function and an autozoom function is attached to a manual focus MF compatible camera body 14A, the MF compatible camera body 14 will be described.
Since A does not support the auto focus function and the auto zoom function, the AF male connector 38D and the zoom male connector 3 provided on the AFZ interchangeable lens 12C are provided.
Although it does not have a female connector for 8C,
The AF male connector 38D and the zoom male connector 38C of the FZ interchangeable lens 12C are housed in the recess 60 formed in the lens mount 16 and do not interfere with other members. It can be attached to the MF compatible camera body 14A.

By the way, if the camera body does not support the function of the interchangeable lens as in the above case, the interchangeable lens cannot be operated by the camera body.

Therefore, in such a case, the operation of the mechanism is switched to manual on the interchangeable lens side. That is, for example, as shown in FIG. 9, an AFZ interchangeable lens 12 having an autofocus function and an autozoom function in a manual focus MF compatible camera body 14A.
When C is attached, the autofocus and autozoom functions cannot be used. Therefore, the focus operation of the taking lens 20 and the zoom operation of the zoom lens 72 on the AFZ interchangeable lens 12C side are performed by the MF / AF switching mechanism 71 and MZ / AZ. Switching is performed by the switching mechanism 75. This allows the AFZ interchangeable lens 12C to function effectively.

The MF / AF switching mechanism 71 and the MZ / A
The switching by the Z switching mechanism 75 may be automatically performed, or may be manually performed by a switch or the like. When it is automatically performed, the connection state of the connector is automatically detected, and switching is automatically performed based on the detection result.

On the other hand, in some cases, the camera body side does not support the function of the interchangeable lens side as described above, but the interchangeable lens side may not support the function of the camera body side.

For example, as shown in FIG. 10, an AF having an autofocus control function and an autozoom control function is provided.
When the MF interchangeable lens 12A for manual focusing is attached to the Z-compatible camera body 14B, the attachment itself can be performed without any problem, but since there is no function corresponding to the MF interchangeable lens 12A side, it is possible to control the autofocus. Unable to control auto zoom.

Therefore, when the interchangeable lens side does not support the function on the camera body side as described above, the camera body detects the connection state of the connector and activates only the function of the connected connector. For example, in the case of FIG. 10, the MPU 52 of the AFZ compatible camera body 14B detects the connection state of the female connectors 62A to 62D and sets only the function corresponding to the connected female connector to be operable. That is, in this case, the video signal female connector 62A and the aperture / shutter control female connector 62
Since only B is connected, only the diaphragm device 22 and the shutter device 24 can be controlled.

It should be noted that such information regarding the control of the interchangeable lens may be stored in the EEPROM 34 incorporated in the interchangeable lens, and this information may be read to set the functions on the camera body side.

FIG. 11 is an overall system view of an interchangeable lens type camera in which an interchangeable lens 12D with a camera shake correction function and a camera body 14C compatible with a camera shake correction are newly added.

The interchangeable lens 12D with a camera shake correction function is
As shown in FIGS. 12 and 13, a camera shake correction unit 76 for performing camera shake correction is added to an AFZ interchangeable lens 12C having an autofocus function and a zoom function. Driver 78
Drive to correct image blur of the subject image due to camera shake or the like. Then, the connection portion 18 is provided corresponding to the camera shake correction function.
In addition, an image stabilization male connector 38E is provided.

On the other hand, a camera body 14C for image stabilization
As shown in FIGS. 12 and 13, the AFZ-compatible camera body 14B is provided with a camera shake correction control function, and is provided with a camera shake prevention circuit 80. The camera shake prevention circuit 80 outputs a drive signal to the unit driver 78 based on the amount of vibration detected by an angular velocity sensor (not shown) provided in the interchangeable lens 12D with a camera shake correction function, and drives the camera shake correction unit 76. To correct image blur. The lens mount 16 is provided with a female connector 62E for camera shake correction corresponding to the control function of the camera shake correction.

Even when the interchangeable lens 12D with a camera shake correction function and the camera body 14C compatible with a camera shake compensation function are added to the system as described above, all the interchangeable lenses should be mounted on all the camera bodies as described above. You can That is, even if there is no corresponding female connector on the camera body side, the male connector is housed in the recess 60 formed in the lens mount 16, so that it cannot be connected by hitting another member on the lens mount side. It can be used effectively without any trouble.

When there is no function corresponding to the camera body side, the interchangeable lens side is switched to manual operation and used as in the above. In the case of the camera shake correction unit 76, use of camera shake correction is disabled.

Similarly, when there is no function corresponding to the interchangeable lens side, the function on the camera body side is set to match the function on the interchangeable lens side.

The correspondence between the function of the interchangeable lens and the function of the camera body in the system shown in FIG. 11 is shown in FIG.
It becomes like the table shown in.

As described above, in the lens interchangeable camera of the present embodiment, the connector for signal transmission is separately provided for each function of the interchangeable lens, and the concave portion 60 (which can accommodate the male connector added later on the camera body side) So-called,
Since the escape is formed, the system can be easily expanded while ensuring compatibility.

On the camera body side, only the function to which the connector is connected is valid, and the function to which the connector is not connected is disabled. Therefore, the functions are the same on the interchangeable lens side and the camera body side. Even if not
Only common features can be used.

On the side of the interchangeable lens, only the function to which the connector is connected can be operated on the camera body side, and the function to which the connector is not connected is the manual operation on the side of the interchangeable lens. Can be used effectively.

In the present embodiment, the male connector is installed on the interchangeable lens side and the female connector is installed on the camera body side, but this relationship may be reversed. In this case, as shown in FIG. 15, a recess 61 is formed in the connecting portion 18 of the interchangeable lens, and the female connectors 39a to 39e are installed in the recess 61. Further, the male connectors 63a to 63e are installed on the end surface of the lens mount 16, and the lens mount 16 is fitted into the recess 61 formed in the connecting portion 18 of the interchangeable lens, whereby the interchangeable lens is mounted on the lens mount 16. .

In the present embodiment, the female connector is provided so as to project into the recess 60 so that the added male connector can be accommodated in the recess 60.
It is also possible to predetermine a position where a male connector will be added in the future and to form a housing portion for housing the male connector on the female connector side, so that the female connector can be embedded in the recess 60. For example, as shown in FIG. 16, a recess 60 formed in the lens mount 16
Male connector 38 installed inside the interchangeable lens 12A
Female connectors 62A and 62B are embedded corresponding to A and 38B. At the same time, male connectors 38C to 3C to be added in the future on the end face of the connecting portion 18 of the MF interchangeable lens 12A.
The position of 8E is determined in advance, and the lens mount 16 is formed with accommodating portions 65C to 65E corresponding to the installation positions of the male connectors 38C to 38E. As a result, even if a male connector is added in the future, the conventional camera body can be effectively used, and the system can be expanded while ensuring compatibility.

Further, in the present embodiment, the connector is installed separately for each function of the interchangeable lens.
The connectors may be installed separately for different types having the same function. For example, the interchangeable lens of the present embodiment has a built-in CCD as an image pickup element. The image pickup element has a honeycomb CCD in which light receiving sensors corresponding to photosensitive pixels are two-dimensionally arranged in a honeycomb shape, There are Bayer CCDs, CMOSs, etc. in a Bayer array, and connectors may be installed separately for each type of this image pickup device.

In this case, for example, an interchangeable lens 12F incorporating a honeycomb CCD, an interchangeable lens 12G incorporating a Bayer CCD, and an interchangeable lens 12 incorporating a CMOS.
In order to allow H and H to be attached to one camera body, as shown in FIG.
The female connectors 66F, 66G, 66H corresponding to the image pickup elements built in the interchangeable lenses 12F, 12G, 12H are embedded in the recess 61 formed in the G, 12H connecting portion 18, and the lens mount 16 of the camera body is also mounted. Then, male connectors 68F, 68G, 68H corresponding to the female connectors 66F, 66G, 66H of the respective image pickup devices are installed.
Further, the interchangeable lenses 12F, 12G, and 12H are formed with accommodating portions 67F, 67G, and 67H that accommodate male connectors other than the corresponding male connectors. For example, the interchangeable lens 12F having a built-in honeycomb CCD has a Bayer C
Housing portions 67G and 67H for housing the male connector 68G for CD and the male connector 68H for CMOS are formed corresponding to the installation positions of the male connector 68G for Bayer CCD and the male connector 68H for CMOS.

In the case of the above configuration, the camera body is set so that the image pickup device corresponding to the connected connector is processed. For example, when the interchangeable lens 12F including the honeycomb CCD is mounted on the lens mount 16, the processing corresponding to the honeycomb CCD is set. In this case, the male connector 68G for Bayer CCD and the male connector 68H for CMOS are
An accommodating portion 70 provided in the connecting portion 18 of the interchangeable lens 12F
G, 70H.

As described above, by separately installing the connectors for each type of the image pickup device, it is possible to make the camera bodies common and to expand the system with compatibility.

[0078]

As described above, according to the present invention,
Even if a male connector is added to the interchangeable lens due to the addition of functions in the future, the camera body already has a space to accommodate the added male connector, so compatibility with conventional products is maintained. The system can be expanded as it is.
