From the left light emitting section 24b to the left light deflecting section 15b
Of the light beam BL2 projected toward the light beam BL2a emitted from the left-side light deflector 15b (prism p2).
Is a focus plate upper surface 15 in a direction substantially orthogonal to the focus plate 15.
The light exits from x and goes to the pentaprism 17. On the other hand, of the light beam BL2, the light beam BL2b emitted from the vicinity of the left light deflection portion 15b on the focus plate upper surface 15x is emitted from the focus plate upper surface 15x at an emission angle substantially similar to the incident angle on the focus plate lower surface 15w. It does not go to the pentaprism 17. In other words, the left light deflector 15 from the focus plate lower surface 15 w side.
The light beam BL2 projected toward the left light deflector 1
Only the light beam emitted from 5b reaches the eyepiece lens 19.
Similarly, of the light beam BL3 projected from the right light emitting unit 24c toward the right light deflecting unit 15c, the right light deflecting unit 1
The light beam BL3a emitted from 5c (prism p3) is emitted from the focus plate upper surface 15x in a direction substantially orthogonal to the focus plate 15, and travels to the pentaprism 17.

The light beam BL3b emitted from the periphery of the focus plate 5c
At the same exit angle as the incident angle to 5w, the focus plate upper surface 15x
Therefore, the light does not go to the pentaprism 17 because the light exits from the pentaprism. In other words, as for the light beam BL3 projected from the focus plate lower surface 15w toward the right light deflection unit 15c, only the light beam emitted from the right light deflection unit 15c reaches the eyepiece lens 19. Even if a part of the light beam from the central light emitting unit 24a enters the left light deflecting unit 15b or the right light deflecting unit 15c, it does not go to the pentaprism 17 by the prism (p2 or p3).

FIG. 3 shows a cross section of the central light deflection section 15a. The central light deflecting unit 15a includes a plurality of prisms p1. The plurality of prisms p <b> 1 are configured as reflection prisms that reflect the incident light from the corresponding central light emitting unit 24 a on the outer surface thereof and guide the incident light to the pentaprism 17.

Among them, the light beam incident on the central light deflecting unit 15a is reflected on the surface of the prism p1, and becomes a reflected light beam BL1a traveling toward the pentaprism 17 in a direction substantially orthogonal to the focus plate 15. On the other hand, of the light beam BL1, the focus plate upper surface 15
The light beam incident on the periphery of the central light deflection unit 15a of x is reflected by the focus plate upper surface 15x to become a reflected light beam BL1b, so that it does not go to the pentaprism 17. That is, as for the light beam BL1 projected from the focus plate upper surface 15x side toward the central light emitting portion 24a, only the light beam reflected by the central light emitting portion 24a (prism p1) reaches the eyepiece lens 19. The central light deflector 15a is provided with a left light deflector 15b or a right light deflector 15
Even if a part of the light beam from c enters, the prism p1
Is not deflected toward the pentaprism 17. Therefore, any of the light emitting units (24a, 24b or 2
4c) irradiates the corresponding light deflectors (15a, 15b).
Alternatively, when the light is incident on 15c), the light deflector is displayed in a light-emitting manner in the finder visual field FV. The display device in the viewfinder of the single-lens reflex camera according to the present embodiment includes a light deflecting unit 15
a, 15b, 15c, each light emitting section 24a, 24b, 24c
And the reflection surface 36a of the prism 36 and the like.

The structure of each light deflecting unit 15a, 15b, 15c formed on the focus plate 15 as described above, and each light emitting unit 2
Due to the arrangement structure of the prisms 36a, 24b, and 24c, when any one of the selected light deflecting units receives and emits light from the corresponding light emitting unit, the peripheral light of the irradiated light is adjacent to the adjacent light deflection unit. Even when the light deflecting unit hits, it is possible to cause only the selected light deflecting unit to emit light without displaying part of the light deflecting unit. That is, for example, as shown in FIG. 10, when the irradiation range of the irradiation light from the right light emitting unit 24c that illuminates the right light deflecting unit 15c is within the range of the circle indicated by the two-dot chain line in the figure, that is, the right light emitting unit 24
Even if a part of the central light deflecting unit 15a is illuminated by the peripheral light of the irradiation light from c, only the right light deflecting unit 15c emits light as shown in FIG. In FIG. 11, a plurality of lines drawn radially around the right light deflection unit 15c indicate that the right light deflection unit 15c is emitting light.

FIG. 8 shows an example of the light deflection section light emission display processing by the body microcomputer 34. AF of this embodiment
In a single-lens reflex camera, when a release button (not shown) is half-pressed, a defocus amount is calculated at each of the center ranging point C, the left ranging point L, and the right ranging point R, and the calculated defocus amount is calculated. When the subject is focused on and the release button is fully pressed, a release operation is performed. When the release button is half-pressed, the process enters the flow chart shown in FIG.

When the release button is half-pressed, first, a defocus amount is calculated at each of the center ranging point C, the left ranging point L, and the right ranging point R (S101). Next, the defocus amount at the distance measuring point at which the minimum defocus amount is calculated is stored in a RAM or the like, and a drive amount for driving the AF lens group of the photographing optical system 41 is obtained based on the defocus amount. Then, the AF lens group is driven by this driving amount (S10).

07, and if it is determined that the subject is in focus, the next step S
The process proceeds to the process of S111 (S109).

In the process of step S111, step S111

The light source 24 of the left light emitting portion 24b or the right light emitting portion 24c)
d is emitted. Subsequently, the timer is started, and then a release permission is issued and a return is made (S113, S11).
5). The timer process in step S113 is performed in step S113.
This is a process of turning off the light source 24d that was turned on in the process of 111 after a predetermined time (for example, 5 seconds) has elapsed from the start of the timer.

As described above, according to the AF single-lens reflex camera of the present embodiment to which the present invention is applied, one of a plurality of focus frames (light deflecting units) provided in the finder field is displayed by light emission. In this case, only the selected focus frame can be illuminated without displaying part of the adjacent focus frame,
Therefore, it is possible to make the photographer visually recognize which focus frame is currently selected.

Further, since the reflecting surface 36a formed on the prism 36 is used to allow the light beam from the central light emitting portion 24a to enter the central light deflecting portion 15a from the focus plate upper surface 15x side, the number of parts is increased. Is suppressed.
A reflecting surface having the same function as the reflecting surface 36a may be formed on a camera component other than the prism 36.

In this embodiment, three light deflecting sections 15a, 15b and 15 functioning as focus frames are provided.
Although c is formed on the focus plate 15, each light deflector may be formed on a transparent plate or the like provided near the focus plate 15 instead of this structure.

In the present embodiment, three light deflecting units functioning as focus frames are provided, and the number of light emitting units corresponding to the three light deflecting units is provided. However, two or four light deflecting units are provided. One or more light-emitting units may be provided, and the number of light-emitting units corresponding to the number of the light deflection units may be provided.

In the present embodiment, the plurality of light deflecting units are configured as focus frames, but may be configured as indices used for other purposes than the focus frame.

In this embodiment, one of the plurality of light deflection units selected by the light deflection unit light emission display processing shown in FIG.
One of the light deflecting units is controlled to emit light. However, the present invention is not limited to this control mode.
A configuration may be employed in which one or more light deflecting units simultaneously emit and display light.

In this embodiment, the central light deflecting section 15a
Is provided as a reflective prism, and the left light deflecting unit 15b and the right light deflecting unit 15c are provided as refracting prisms. Instead of this configuration, the central light deflecting unit 15a is provided as a refracting prism, and the left light deflecting unit 15b is provided. The same effect can be obtained by providing the right light deflecting unit 15c as a reflective prism. In this case, the light beam from the central light emitting portion 24a is directly incident on the central light deflecting portion 15a, and the light beams from the left light emitting portion 24b and the right light emitting portion 24c are respectively deflected through the reflecting surface 36a of the prism 36. What is necessary is just to make it the structure which makes it inject | pour into a part (15b or 15c).

In the present embodiment, the present invention is applied to an AF single-lens reflex camera. However, the present invention can be applied to a lens shutter camera.
