Abstract

PROBLEM TO BE SOLVED: To enable not only an operation value set every specified turning angle of a rotary type operation member but also the intermediate value thereof to be set by combining the rotary type operation member and a reciprocating moving type operation member. SOLUTION: When a rotary dial 10 is rotated so as to change shutter speed after the intermediate value is set, a canceling lever 17 is moved in a direction that it is separated from the dial 10 because the tip small-diameter part thereof is pressed by the projecting part 16a of a cam plate 16. By the movement of the lever 17, an interlocking projection 24 is pressed by a return tapered surface so that a slider 20 is returned to a neutral position. When the dial 10 is turned to the position of a next shutter speed value, the tip small-diameter part is engaged with a recessed part 16b and returned except the position of the projection 24. On this condition, the set and the release of the intermediate value can be freely executed again by the slider 20. Besides, the finer operation value can be set.

A brush body 31 that rotates integrally with the shaft 11 is provided on the inner surface of the support substrate 30, and the brush body 31 is in contact with a dial code plate 32 fixed in the support substrate 30. Similarly, the slider 20 is supported by the support substrate 30 so as to be able to reciprocate and rectilinearly move. A slide switch 23 that operates by sliding operation of the slider 20 is provided on the support substrate 30. Depending on the brush body 31 and the dial code plate 32, a large amount of shutter speed information can be obtained.
Information on three positions with the positions on both sides thereof is obtained.

3 shows a circuit for setting the shutter speed by the (brush body 31) and the slide switch 23. Shutter speed information set by the dial code plate 32 (brush body 31) and the slide switch 23 is input to the CPU 33, and The shutter speed of the control focal plane shutter 34 is controlled.

FIGS. 7 and 8 show an automatic return mechanism of the slider 20. FIG. The rotary dial 10 is provided with a cam plate 16 that rotates integrally. This cam plate 16
On its outer peripheral surface, a concave portion 16b corresponding to each shutter speed value 12 and a convex portion 16a corresponding to the black circle intermediate mark 14 are provided.
And a large-diameter portion 16c that disables operation of the slider 20. A cancel lever 17 is supported on the support substrate 30 so as to be movable in the radial direction of the rotary dial 10. The cancel lever 17 is biased by a compression spring 18 in a direction in which the cancel lever 17 comes into contact with the outer peripheral surface of the cam plate 16. Have been. 35 and 36 are movement guides of the cancel lever 17. The large diameter portion 16c is the rotary dial 1 of FIG.
Corresponding to a section X of 0, the click is stopped by a click stop mechanism (not shown).

The cancel lever 17 is provided at the tip small diameter portion 17.
a and a function hole 17b into which the interlocking projection 24 provided integrally with the slider 20 fits. The small-diameter portion 17a is formed by a convex portion 16a, a concave portion 16b, and a large-diameter portion 16c of the cam plate 16.
To move the cancel lever 17 to the moving guide 35,
Move along 36. The function hole 17b has a size that allows a forward / reverse sliding operation from a neutral position of the slider 20 in a state where the small-diameter portion 17a is in contact with the concave portion 16b. On the other hand, the rotary dial 1 of this function hole 17b
On the 0 side, a pair of left-right symmetric return taper surfaces 17c and a lock hole 17d provided continuously between the distal ends of the pair of return taper surfaces 17c are formed. Return taper surface 17c
After the slider 20 (interlocking projection 24) is moved from the neutral position to one of the forward and reverse operation positions, the rotary dial 10 is rotated, and as a result, the cancel lever 17 is pushed by the convex portion 16a. Then, the interlocking projection 24 is pushed to return to the neutral position. When the rotary dial 10 is rotated and the small-diameter portion 17a is pushed by the large-diameter portion 16c, the locking hole 17d is provided with the interlocking projection 24 therein.
And does not allow the slider 20 to move.

Therefore, the mechanism shown in FIGS. 7 and 8 operates as follows. When the rotary dial 10 is rotated while the slider 20 is in the neutral position, each time each shutter speed value 12 matches the position of the stop index 21, the small-diameter portion 17 a of the tip of the cancel lever 17 is moved to the concave portion of the cam plate 16. 16b. At this time, at the same time, a click stop is applied by a click stop mechanism (not shown). At this time, the set shutter speed is set to the dial code plate 32.
The data is input to the CPU 33 via the (brush body 31).

Next, when the slider 20 at the neutral position is slid forward or backward in a state where the small-diameter portion 17a is engaged with any of the concave portions 16b, the interlocking projection 24 is moved into the function hole 17b. And the stop index 21 matches any of the black circle intermediate marks 14. At this time, the set shutter speed (the intermediate shutter speed value between the adjacent shutter speed values 12) is determined by the dial code plate 32 (the brush body 31) and the slide switch 23.
Is input to the CPU 33 via the. FIG. 8A shows the position of the interlocking projection 24 of the slider 20 in the function hole 17b when the intermediate value is set. In this state, by operating the slider 20, the set intermediate value can be canceled and the intermediate value set in the reverse direction can be freely set.

After setting the intermediate value in this way, when the rotary dial 10 is rotated to change the shutter speed, the canceling lever 17 is pushed by the convex portion 16a of the cam plate 16 at the tip small diameter portion 17a, and the rotation is stopped. It moves in a direction away from the dial 10. Then, by the movement of the cancel lever 17, the return taper surface 17c pushes the interlocking projection 24 to return the slider 20 to the neutral position (FIG. 8B). Then, when the rotary dial 10 rotates to the position of the next shutter speed value 12, the tip small diameter portion 17a engages with the concave portion 16b, and returns to the state of FIG. 8A except for the position of the interlocking projection 24. . Therefore, in this state, the setting and release of the intermediate value can be freely performed by the slider 20 again.

On the other hand, when the rotary dial 10 enters the rotation section of the section X, the large-diameter portion 16c engages with the tip small-diameter portion 17a to further move the cancel lever 17 radially outward of the rotary dial 10. . Then, the interlocking protrusion 24 is fitted and locked in the lock hole 17d, and the slider 20 cannot be slid from the neutral position. In the above description, a click stop mechanism that determines the rotation stop position of the rotary dial 10 is provided separately from the cancel lever 17 and the cam plate 16, but the cancel lever 17 and the cam plate 16 also serve as a click stop mechanism. You can also.

In the above embodiment, the shutter speed value 12 of the rotary dial 10 is every 1 EV.
If it is possible (necessary) to set the value to / 2EV, an intermediate value can be set for each 1 / 4EV by operating the slider 20. In short, according to the present invention, an intermediate value of an operation value that can be set by the rotary dial 10 can be set by the slider 20.

[0023]

According to the present invention, not only the operation value displayed at the click stop of the rotary operation member but also an intermediate value thereof can be set by the reciprocating operation member. , It is possible to set more detailed operation values without increasing the click stop pitch.
