Etc., the two operating members are not provided close to each other. The display unit is provided near the second operation member.

However, it is not ergonomically preferable that the first and second operation members are not arranged close to each other, and in this type of imaging information setting device, while visually recognizing the display on the display unit. Since the first and second operation members are operated to change to desired setting values, it is preferable that the operation member and the display unit are close to each other in order to prevent erroneous operation. Has a problem that the first operation member is separated from the display unit. Further, since the first and second operation members and the display section are not positionalally associated with each other, it is easy to make an erroneous operation, and in particular, confusion occurs when the shooting position of the camera is changed from portrait to landscape. Cheap.

(Object of the Invention) An object of the present invention is to solve the above problems, and to provide a photographing information setting device for a camera, which prevents erroneous operations and improves usability.

Next, the switches 10 and 20 will be described in detail with reference to FIG.

The anchor-shaped switch body 101 is rotatably attached to a shaft 102 provided in the upper cover 4, and its operation protrusion 101a is provided.
However, it is projected from the opening 421 of the rear surface 42 of the upper cover. Axis 1
A torsion coil spring 103 made of a conductive material is attached to 02, and its fixed arm 103a is connected to the camera body 1,
The working arm 103b at the other end is the two protrusions 101b of the switch body 101.
And 101c, the operating projection 101a is naturally held at the intermediate position of the opening 421 as shown in FIG. In the switch body 101, the operation protrusion 101a has an opening 421.
5 is rotatable in the upward direction (arrow Up direction) against the spring force of the spring 103 until it abuts the upper end 421a of the spring 103, and the spring of the spring 103 abuts the lower end 421b of the opening 421. It is rotatable in the downward direction (arrow Dn direction) in FIG. 5 against the force.

Further, the contact pins 104 and 105 are sandwiched by the splashing arm 103b.
Is fixed to the camera body 1 in an electrically insulated state, and the contact pins 104 and 105 have leads 106 respectively.
And 107 are connected. Each lead 106, 107 is connected to an electric circuit (not shown), and when the switch body 101 is operated in the Up direction and the working arm 103b comes into contact with the contact pin 104, the lead 106 → contact pin 104 → working arm 103b → fixed arm 103a → camera A current flows through the path of the main body, and it is detected that the switch 10 has been operated in the Up direction. When the switch body 101 is operated in the Dn direction and the working arm 103b comes into contact with the contact pin 105, the lead 107 → the contact pin 105 → the working arm 103b → the fixed arm 103a.
→ An electric current flows in the path of the camera body 1 and it is detected that the switch 10 is operated in the Dn direction. When the operation in the Up direction or the Dn direction is detected in this way, the aperture value and the shutter speed displayed on the display units 61 and 62 are changed by the control circuit (not shown). Since the switch body 101 is rotated until it comes into contact with the open ends 421a and 421b even after the working arm 103b comes into contact with the contact pins 104 and 105, the working arm 103b bends, and the spring 103 and the contact pins 104 and 105 A certain contact pressure is obtained in between. Switch body 101 in that state
If is released, the spring force of the spring 103 causes the spring 103 to return to the intermediate position shown in FIG. The switch 20 has the same structure.

When the camera including the photographing information setting device configured as described above is provided, the lower part of the photographing lens is supported by the left hand, and the thumb of the right hand is applied to the flat surface portion 71 of the finger rest 7 while the grip portion is being held.
1a and the back cover grip 2a are supported by the entire right hand, and the index finger of the right hand is lightly placed on the release button 5. At this time, the guards 72 and 73 of the finger rest 7 prevent the thumb from accidentally touching the switches 10 and 20. Then, in order to change the aperture value while shooting in this shooting position, the thumb of the right hand may be moved away from the finger rest 7 and placed on the switch 10 and operated in the Up direction or the Dn direction. The same applies to the change in shutter speed.

The following effects can be obtained in the embodiment described above.

That is, in the case where the operation member operated to change the aperture value and the shutter speed is provided on the upper surface of the camera upper cover, that is, in the vicinity of the release button, the operation member applied with the index finger of the right hand is used. Each time the setting is changed, the index finger on the release button must be carried to the operation member, but as in this embodiment, the right thumb can be used to change the aperture value and shutter speed. By operating the operation members 10 and 20, it is not necessary to release the index finger from the release button every time the photographing information is changed, and the photographing information changing operation can be performed quickly. The left side of the finger rest 7 is the operation member 1 for changing the aperture value.
0 and the right side are the operation members 20 for changing the shutter speed, and even if the shooting position changes, the thumb of the right hand is applied to the finger rest, so that the desired operation member can be easily viewed while looking through the finder 3. It is possible to carry the right thumb on the desired operating member without confusion.

In addition, regardless of the shooting state of the camera, in other words, regardless of whether the camera is held vertically or horizontally, operating the operation members 10 and 20 in the direction of the top surface of the camera upper cover will increase the aperture value (close down), Since the shutter speed is configured to be fast (shift to the high speed side), if the operating direction of each operating member is different, for example, the operating member for changing the aperture value should be placed in the vertical direction of the camera, Compared with the case where the operation member for time change is operated in the left-right direction of the camera, confusion in operation is reduced and usability is improved.

Further, if the two operating members 10 and 20 are not arranged on the upper cover upper surface as in the embodiment, it is possible to arrange a larger and multifunctional display portion on the upper cover upper surface.

(Effect of the Invention) According to the present invention, when viewed from the side of a photographer who holds the camera, the first display section and the first display section are arranged so that they are arranged in the same manner as the first operation member and the second operation member. Since the second display unit is arranged next to each other, the first operation member and the first operation member
The corresponding relationship between the display section, the second operation member and the second display section is clarified. Therefore, the aperture value and the shutter speed are changed while checking the first display section and the second display section. In this case, there is no fear of deciding which of the first operation member and the second operation member should be operated. Moreover, since the first operating member and the second operating member are located in opposite directions to the finger rest, the first operating member and the second operating unit are in other words, while checking the display contents of the first and second display units. Even without visually confirming the positions of the operation member and the second operation member, the operation member on the desired side of the first operation member and the second operation member can be swiftly and quickly operated by the photographer's specific finger. The operation can be reliably performed, and there is no possibility that the photographing information is changed undesirably by operating the operation member on the opposite side. As a result, operability is improved and erroneous operation is prevented, and in particular, operational confusion that occurs when the camera is changed from portrait to landscape, and the like is prevented.
