Description

[Detailed Description of the Invention] The present invention relates to a strobe operating member for a camera with a built-in strobe.

Recently, more and more cameras with built-in strobes, which anyone can easily use to take pictures, are equipped with an exposure compensation function that is effective for shooting against backlight. That's not at all a desirable thing.

Constructing the strobe operating member and the exposure compensation member from the same member and having two functions in one operating member provides the user with easy operability, but when the strobe is set, the exposure In the case of a camera that does not function due to the circuitry even after correction is applied, the user will not have any doubts about the movement of the operating member if the operating member cannot be moved from the strobe set position to the exposure compensation position. It should be.

The present invention provides the user with a fully proof operating member with simple operation.

In order to achieve the above object, the strobe operating member according to the present application includes an external operating member that can be positioned at a strobe set operating position and an exposure correction operating position by sliding in mutually opposite directions from a normal position;
a strobe member movable between a use position and a non-use position; A locking member that locks the strobe member in a non-use position at the exposure compensation operation position and releases the lock at the strobe set operation position, and a lock that biases the locking member toward the exposure compensation operation position. a stop member biasing means; an external operation member biasing means for biasing the external operation member toward the strobe set operation position with respect to the locking member;
The strobe member has a holding means for holding the locking member in the unlocked position in the use position, and when the strobe member is not in use, the locking member is provided with the locking member biasing means. The external operating member is biased toward the strobe set operating position with respect to the locking member by the external operating member biasing means. The locking member is interlocked with the movement of the external operating member to the strobe set operating position, and the locking of the strobe member to the non-use position is released, and the strobe member is not in the use position. A sliding operation of the external operating member to the exposure correction operating position is restricted by the locking member held at the unlocked position by the holding means of the strobe member, and is prohibited.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is an external view of a camera with a built-in strobe. In the figure, the operating member 1 as an external operating member is in its normal position. To enter the exposure correction state, slide the operating member 1 toward the inside of the camera. In the figure, it is at +1.5 position. To put the strobe into use, slide the operating member 1 toward the outside of the camera. In the figure, it is at the 〓 position. When the strobe light is in use, the strobe light emitting section 2 is raised from the camera body by the interlocking mechanism, and after the strobe light emission photographing is completed, the strobe light emitting section 2 is housed in the camera body.

FIG. 2 is a configuration diagram when the operating member 1 is in the normal position. The operating member 1 is held slidably in the lateral direction by a guide member on the camera body side (not shown), and an exposure compensation switch contact piece 11 is fixed to one end of the operating member 1. The tips 11a and 11b of the exposure compensation switch 11 are in contact with the exposure compensation switch circuit board 20, and when the operating member 1 is slid to the exposure compensation position, the tips 11a and 11b are in contact with the exposure compensation switch circuit board 20.
1a and 11b are exposure compensation switch circuit boards 20;
It rides on the upper lands 20a and 20b, and the exposure compensation circuit is closed. A locking plate 4 as a locking member slidably attached to the guide grooves 3a and 3b of the camera body is pushed toward the camera body wall 3c side, which is the exposure correction operation position side, by a spring 5 as a locking member biasing means. It is biased and has a stroke that allows the operating member 1 to move from the normal position to the strobe set position.

The corner convex portion 1a of the operation member 1 is connected to a spring 6 as an external operation member biasing means incorporated between the locking plate 4 and the corner convex portion 1a.
Therefore, the operating member 1 is biased toward the interlocking surface 4a, and has a stroke between the corner convex portion 1a and the locking plate 4 that allows the operating member 1 to move from the normal position to the exposure correction position.

The strobe body 7 as a strobe member is configured to be able to slide upward by a spring and a guide groove (not shown), and is moved laterally within the hook portion 4b of the locking plate 4 and the groove 7a of the strobe body 7. By doing so, the strobe body 7 is raised and retracted. In the figure, the hook portion 4b is in contact with the upper abutment surface 7b of the groove 7a, and prevents the strobe body 7 from sliding upward.

FIG. 3 is a configuration diagram when the operating member 1 is slid to the exposure correction position.

When the operating member 1 is slid from the normal position toward the exposure compensation position, the increased spring pressure of the spring 6 is applied to the locking plate 4, and the locking plate 4 attempts to move to the left in the drawing, but the locking plate 4 is in contact with the camera body wall 3c and does not move.

When the corner convex portion 1a of the operating member 1 comes into contact with the convex portion 4c of the locking plate 4, the tip portion 11 of the exposure compensation switch 11
a and 11b rest on lands 20a and 20b on the exposure compensation switch circuit board 20, and the exposure compensation circuit is closed.

In order to return the operating member 1 from the exposure correction position to the normal position, it is sufficient to release the finger from the operating member 1.

The operating member 1 is moved to the right in the drawing by the spring pressure of the spring 6, and the corner convex portion 1a abuts the interlocking surface 4a of the locking plate 4, so that it is in the normal position.

FIG. 4 is a configuration diagram when the operating member 1 is slid to the strobe set position.

When the operating member 1 is slid from the normal position toward the strobe set position, the locking plate 4 moves to the right in the drawing, which is the strobe set operating position side, and comes into contact with the camera body wall 3d to reach the strobe set position.

When the hook portion 4b of the strobe body 7 is disengaged from the upper contact surface 7b of the groove 7a, it slides upward by a spring and guide groove (not shown), and the hook portion 4b comes into contact with the lower contact surface 7c of the groove 7a. The flash will be in use. In this state, the hook portion 4b comes into contact with the side abutment surface 7d of the groove 7a as a holding means,
Movement of the locking plate 4 is prevented.

When the operating member 1 is now slid to the left in the drawing, the corner protrusion 1 a comes into contact with the protrusion 4 c of the locking plate 4 . This stroke is the distance that the operating member 1 moves from the normal position to the exposure compensation position, but the locking plate 4
Since the operating member 1 moves to the strobe set position and is fixed, the operating member 1 only moves from the strobe set position to the normal position. To store the strobe body 7, by pushing down the upper part of the strobe body, the side abutment surface 7d of the groove 7a is removed from the hook part 4b, and the locking plate 4 is moved to the left in the drawing by the spring 5. In conjunction with this movement, the operating member 1 self-returns to its normal position.

As described above, according to the present invention, even if exposure compensation is applied in the strobe set state, in the case of a camera that does not function due to the circuit, it is possible to prevent the operating member from moving from the strobe set position to the exposure compensation position.
Preventing users from having doubts regarding operation,
The operating parts are fully proof-proof.
