The heat radiating unit 90 is, for example, a finder case unit 3a. Further, the heat radiating portion 90 may have a structure arranged inside the finder case portion 3a, for example. The heat radiating portion 90 is a portion arranged in a fixed state, and it is desirable that the heat radiating portion 90 is formed of a material having high heat radiating properties, for example, a metal material.

In a state where the second connecting portion 55 is pressed against the heat radiating portion 90 from behind, the second connecting portion 55 of the heat transfer portion 11 is attached to the sticking plate 45 via the cushion 49, and a part of the cushion 49 is attached. Since it protrudes forward from the sticking plate 45, the second connecting portion 55 is pressed against the heat radiating portion 90 by the elasticity of the cushion 49, and the second connecting portion 55 is connected in a state of being in surface contact with the heat radiating portion 90. ..

As described above, the elasticity of the cushion 49 presses the second connecting portion 55 against the heat radiating portion 90, and the second connecting portion 55 comes into contact with the heat radiating portion 90 without passing through the adhesive sheet, whereby the second connecting portion 55 is brought into contact with the heat radiating portion 90. It is possible to secure high conduction efficiency of heat conducted from the connecting portion 55 to the heat radiating portion 90.

However, the second connecting portion 55 may be attached to the heat radiating portion 90 by an adhesive sheet.

As described above, in the finder 6, the first connection portion 52 of the heat transfer unit 11 is connected to the display unit 32b of the display panel 32, and the second connection portion 55 of the heat transfer unit 11 is connected to the heat dissipation unit 90. Therefore, the heat generated in the display unit 32b is conducted to the heat radiating unit 90 by the heat transfer unit 11.

<Operation in the viewfinder>
The operation of the finder 6 configured as described above will be described below (see FIGS. 8 to 10).

In the finder 6, the movable block 9 is moved in the optical axis direction with respect to the optical block 8, the relay unit 10, and the heat radiating unit 90. The movement of the movable block 9 with respect to the optical block 8 is performed by rotating the rotary cam 25 with the operation of the diopter adjustment dial 29, and the display panel 32 moves with the movement of the movable block 9. It is moved in the direction of the optical axis. Therefore, by moving the display panel 32 in the optical axis direction with respect to the optical block 8, the position of the display panel 32 with respect to the lens 13 of the optical block 8 in the optical axis direction is changed, and the diopter adjustment is performed.

The display panel 32 is located between the first moving position, which is the rear moving end located closest to the lens 13, and the second moving position, which is the front moving end located farthest from the lens 13. It is movable in the optical axis direction.

In the state where the display panel 32 is in the first moving position, the amount of deformation of the first portion 53a in the first deformed portion 53 with respect to the first connecting portion 52 and the first deformed portion with respect to the second connecting portion 55. The amount of deformation (bending amount) of the second portion 53b in 53 is minimized, and the distance between the first connecting portion 52 and the second connecting portion 55 is maximized (see FIG. 8). Therefore, the distance between the bent portion 57 of the first deformed portion 53 and the bent portion 60 of the second deformed portion 54 is maximized in the vertical direction.

When the display panel 32 is moved from the first moving position to the second moving position, the amount of deformation of the first deformed portion 53 and the second deformed portion 54 is increased, and the first connecting portion is formed. The distance between the 52 and the second connecting portion 55 becomes smaller (see FIG. 9).

When the display panel 32 is moved to the second moving position, the amount of deformation of the first deformed portion 53 and the second deformed portion 54 becomes the largest, and the first connecting portion 52 and the second connecting portion 55 The distance is minimized (see FIG. 10). Therefore, the distance between the bent portion 57 of the first deformed portion 53 and the bent portion 60 of the second deformed portion 54 is the smallest in the vertical direction.

On the contrary, when the display panel 32 is moved from the second moving position to the first moving position, the amount of deformation of the first deformed portion 53 and the second deformed portion 54 becomes the smallest, and the first connecting portion The distance between the 52 and the second connecting portion 55 is maximized (see FIG. 8).

When the display panel 32 is moved between the first moving position and the second moving position in this way, the deformation amounts of the first deformed portion 53 and the second deformed portion 54 are changed to expand and contract, and the first deformed portion 53 and the second deformed portion 54 are expanded and contracted. A load is hardly applied to the display panel 32 from the deformed portion 53 of 1 and the second deformed portion 54.

The heat generated in the display panel 32 is conducted to the heat radiating section 90 by the heat transfer section 11, and is discharged from the heat radiating section 90 toward the outside of the outer casing 3. Therefore, the temperature rise of the display panel 32 is suppressed, and a good driving state of the display panel 32 is ensured.

As described above, the heat transfer unit 11 is provided with a first connection unit 52 connected to the display panel 32 and a second connection unit 55 connected to the heat radiation unit 90, and the heat transfer unit 11 is provided with a second connection unit 55. A first deformed portion 53 and a second deformed portion 54 are provided between the connecting portion 52 of 1 and the second connecting portion 55.

Therefore, the first deformed portion 53 and the second deformed portion 54 are deformed between the first connecting portion 52 and the second connecting portion 55 according to the moving position of the display panel 32 with respect to the heat radiating portion 90. While ensuring miniaturization, the heat generated in the display panel 32 can be efficiently released regardless of the relative moving position of the display panel 32 with respect to the heat radiating portion 90.

Further, when the display panel 32 is moved, the first deformed portion 53 and the second deformed portion 54 are expanded and contracted according to the movement of the display panel 32 with respect to the heat radiating portion 90.

Therefore, since the first deformed portion 53 and the second deformed portion 54 are deformed by being expanded and contracted according to the movement of the display panel 32 with respect to the heat radiating portion 90, the first deformed portion 53 and the second deformed portion 53 and the second deformed portion 54 are deformed in a small space. The deformed portion 54 can be deformed, and the heat generated in the display panel 32 can be efficiently released without increasing the size of the finder 6.

Further, since the first deformed portion 53 and the second deformed portion 54 are deformed in a state of being positioned in the space 200 formed between the display panel 32 and the heat radiating portion 90, the first deformed portion 53 and the second deformed portion 54 are deformed. The deformed portion 54 of 2 is not positioned outside the display panel 32 in the direction orthogonal to the optical axis direction. Therefore, the proper moving state of the display panel 32 and the first deformed portion 53 and the second deformed portion 54 are secured by avoiding the interference between the heat transfer portion 11 and other members located outside the display panel 32. be able to.

Furthermore, since the first deformed portion 53 and the second deformed portion 54 are located in the space 200, the existing region of the heat transfer portion 11 becomes smaller, and the display panel 32 is displayed after ensuring the miniaturization of the finder 6. The generated heat can be efficiently released.

Further, the first deformed portion 53 and the second deformed portion 54 are provided apart from each other in the direction orthogonal to the optical axis direction, and the heat generated in the display panel 32 is generated in the plurality of first deformed portions 53 and the second deformed portion 53. It is transmitted to the heat radiating section 90 via the deforming section 54.

Therefore, there are a plurality of heat transfer paths from the display panel 32 to the heat radiating unit 90, and the heat radiating efficiency of the heat generated in the display panel 32 can be improved.

In the above, the heat transfer portion 11 having two heat transfer paths of the first deformed portion 53 and the second deformed portion 54 is shown as an example, but the heat transfer portion 11 is referred to as the first deformed portion 53. Only one of the second deformed portions 54 may be provided.

Further, the first deformed portion 53 and the second deformed portion 54 are positioned substantially symmetrically with respect to the reference axis J extending in the optical axis direction through the central point in the direction orthogonal to the optical axis direction of the heat transfer portion 11. There is.

Therefore, since the first deformed portion 53 and the second deformed portion 54 located at positions substantially symmetrical with respect to the display panel 32 are deformed, the display panel 32 is deformed from the first deformed portion 53 and the second deformed portion 54. It is difficult to apply a load in a biased direction, and the display panel 32 can be moved with respect to the heat radiating unit 90 in a stable state.

Furthermore, three

bent portions

56, 57, 58 and

bent portions

59, 60, 61 are formed in the first deformed portion 53 and the second deformed portion 54, respectively.

Therefore, since the first deformed portion 53 and the second deformed portion 54 are deformed with reference to the

bent portions

56, 57, 58 and the

bent portions

59, 60, 61, the first deformed portion 53 and the second deformed portion 53 and the second deformed portion 54 are deformed. The configuration and operation of the deformed portion 54 of the above are simple, and the configuration of the heat transfer portion 11 can be simplified.

Further, since the heat transfer portion 11 is formed in a sheet shape and the sheet-shaped heat transfer portion 11 is deformed according to the movement of the display panel 32 with respect to the heat radiation portion 90, the heat transfer portion 11 is deformed in a small space. At the same time, the heat transfer unit 11 becomes lighter, and the heat generated in the display panel 32 can be efficiently discharged without increasing the size and weight of the finder 6.

Further, since the heat transfer unit 11 is formed in an annular shape by one sheet-like member, the heat generated in the display panel 32 by the annular heat transfer unit 11 is conducted to the heat radiation unit 90, so that the heat transfer unit 11 Can be efficiently released to the display panel 32 without increasing the number of parts by forming the above with one member.

Furthermore, since graphite sheet is used as the heat transfer unit 11 and graphite is a material having high thermal conductivity and flexibility, the heat transfer efficiency from the display panel 32 to the heat dissipation unit 90 can be improved. At the same time, it is possible to reduce the load applied to the display panel 32 by the heat transfer unit 11.

Further, the finder 6 is provided with an optical block 8 arranged in a fixed state and a movable block 9 to which a display panel 32 is attached, and the movable block 9 is moved in the optical axis direction with respect to the optical block 8. As a result, the display panel 32 is moved with respect to the heat radiating unit 90.

Therefore, the optical block 8 and the movable block 9 can be provided with a structure for moving in the optical axis direction, and the display panel 32 can be moved in the optical axis direction regardless of the shape, size, and type of the display panel 32. It is possible to improve the degree of freedom in design.

Further, a relay unit 10 attached to the optical block 8 is provided, and a second connection portion 55 of the heat transfer unit 11 is attached to the relay unit 10.

Therefore, since the heat transfer unit 11 is connected to the heat dissipation unit 90 with the heat transfer unit 11 attached to the relay unit 10 attached to the optical block 8 arranged in a fixed state, the heat transfer unit 11 of the heat transfer unit 11 The position accuracy with respect to the heat radiating unit 90 is improved, and the heat transfer unit 11 can be connected to the heat radiating unit 90 in a stable state.

In addition, since the second connecting portion 55 is pressed against the heat radiating portion 90 by the elasticity of the cushion 49 and the second connecting portion 55 is connected to the heat radiating portion 90 in a surface contact state, the heat transfer portion 11 is second. A stable contact state with the heat radiating portion 90 of the connecting portion 55 is ensured, and the heat transfer efficiency of the heat generated in the display panel 32 to the heat radiating portion 90 can be improved.

<Modification example of heat transfer part>

bent portions

The heat transfer portion 11B according to the second modification is bent so that the first deformation portion 53 is located outside (upper side) of the space 200 (see FIG. 12). However, the heat transfer portion 11B according to the second modification may be bent so that the second deformation portion 54 is located outside (lower side) of the space 200.

The heat transfer portion 11C according to the third modification is bent so that the first deformation portion 53 and the second deformation portion 54 are located outside the space 200 (see FIG. 13).

It becomes possible to improve the workability in. Further, in order to reduce the size of the heat dissipation structure, it is effective to make the first deformed portion 53 and the second deformed portion 54 inwardly folded so as to be located in the space 200. At least a part of the first deformed portion 53 and the second deformed portion 54 may be configured to be outwardly folded due to an increase in transmission paths and convenience of assembly workability.

The heat transfer portion 11D according to the fourth modification is provided with a third deformation portion 67 in addition to the first deformation portion 53 and the second deformation portion 54 (see FIG. 14).

The number of bent portions of the third deformed portion 67 is arbitrary, and the bent portions may be either mountain-folded or valley-folded.

Since the heat transfer portion 11D has a third deformed portion 67 in addition to the first deformed portion 53 and the second deformed portion 54, there are three heat transfer paths from the display panel 32 to the heat radiating portion 90. Therefore, it is possible to further improve the heat dissipation efficiency of the heat generated in the display panel 32.

They are separated in the direction. The number of bent portions of the fourth deformed portion 68 is arbitrary, and the bent portions may be either mountain-folded or valley-folded.

Since the heat transfer portion 11E has a fourth deformed portion 68 in addition to the first deformed portion 53, the second deformed portion 54, and the third deformed portion 67, the heat transfer portion 11E is transferred from the display panel 32 to the heat radiating portion 90. The number of heat transfer paths is four, and the heat dissipation efficiency of the heat generated in the display panel 32 can be further improved.

Further, in the heat transfer portion 11E, the first deformed portion 53 and the second deformed portion 54 are positioned vertically separated from each other, and the third deformed portion 67 and the fourth deformed portion 68 are separated from each other to the left and right. Therefore, it is difficult to apply a load from the first deformed portion 53, the second deformed portion 54, the third deformed portion 67, and the fourth deformed portion 68 to the display panel 32 in a biased direction, and the display panel 32 Can be moved with respect to the heat radiating unit 90 in a stable state.

In the above description, the configuration in which the number of heat transfer paths from the display panel 32 to the heat radiation unit 90 is four or less has been described, but in the finder 6, the number of heat transfer paths is five or more due to the configuration of the heat transfer unit. May be good. Further, the heat transfer unit 11 (including the heat transfer unit 11A to the heat transfer unit 11E) has a configuration in which two deformed portions located between the first connection portion 52 and the second connection portion 55 are located on the left and right. It may be set to.
