ある。2. Description of the Related Art A diopter adjusting mechanism provided in a viewfinder device of a camera moves an eyepiece in the optical axis direction via a cam by a movement of an operating member which moves linearly, or a dial type operation. Generally, the rotation of the member is converted into a linear motion by a cam to move the eyepiece in the optical axis direction. In such a diopter adjustment mechanism, if the operation member moves undesirably due to camera vibration or the like after the diopter adjustment, the lens moves in conjunction with that and the diopter changes, so that the operation member frictionally slides. The operation member is prevented from being undesirably moved by providing a property or providing a ratchet mechanism. However, if a large-scale mechanism such as a ratchet mechanism is provided, there is a problem that the number of parts is increased and the assembling work is complicated, resulting in an increase in cost.

装されている。The eyepiece 17 is held by a holding frame 26 and is movable in the optical axis direction for adjusting diopter.
A diopter dial 24 is supported below the eyepiece 17 so as to be rotatable about the axis 3a.
The diopter is adjusted by operating. The diopter dial 24 has an operation unit 24A on the right side in the figure and a cam unit 2 on the left side.
4B are integrally formed, and a non-slip knurl 24a is formed on the outer peripheral surface of the operation portion 24A. A part of the knurled part is exposed to the outside from the camera body 2 and is used for user operation. The cam portion 24B has a cam surface 24c as shown in FIG. 4 and a projection 24b for regulating the rotation of the diopter dial 24. Between the diopter dial 24 and the receiving surface 3e of the housing 3, a friction member 25 made of an annular silicon rubber or the like for preventing undesired rotation of the diopter dial 24 is interposed.

当接する。FIG. 2 is an enlarged view showing a moving mechanism of the eyepiece 17, showing a state in which the diopter dial 24 and its holding portion have been removed. A tube 26a is integrally formed with the holding frame 26 of the eyepiece 17, and the tube 26a is slidably held in the optical axis direction by a guide rod 28 held by the holding portions 3c and 3d of the housing 3. ing. A cam interlocking portion 26b extending downward in the front of the figure is provided on the tube portion 26a.
Which comes into contact with the cam surface 24c of the diopter dial 24.

ズ１７が振動等で不所望に移動することが防止される。A compression coil spring 27 for loosening is interposed between the holding frame 26 and the housing 3, and the spring 27 urges the holding frame 26 leftward in the drawing to form a cam interlocking portion 26b.
Is always in pressure contact with the cam surface 24c of the diopter dial 24. Therefore, the cam interlocking portion 26b reliably follows the movement of the cam surface 24c due to the rotation of the diopter dial 24, and drives the holding frame 26, that is, the eyepiece 17, in the optical axis direction to adjust the diopter. Also, the urging force of the spring 27 prevents the eyepiece 17 from moving undesirably due to vibration or the like.

７の不所望な移動による視度の変化が防止される。The urging force of the spring 27 also presses the diopter dial 24 against the friction member 25 via the cam interlocking portion 26b and the cam surface 24c. As a result, the friction member 25 is pinched between the diopter dial 24 and the receiving surface 3 e of the housing 3, and generates an appropriate frictional force against the rotation of the diopter dial 24. Therefore, the diopter dial 24 does not move due to camera vibration or the like, and the eyepiece 1
The change in diopter due to the undesired movement of No. 7 is prevented.

により約３００度の角度範囲で回転可能とされる。FIG. 3 is a view seen from the right side of FIG. 2 and shows a state where the diopter dial 24 is attached. The rotation of the diopter dial 24 is restricted by the protrusion 24b formed on the cam portion 24B abutting on the restricting portion 3b of the housing 3, whereby the diopter dial 24 can be rotated within an angle range of about 300 degrees.

合である。As described above, in the present embodiment, the diopter dial 24 is pressed against the friction member 25 by the backlash spring 27 of the eyepiece 17 to increase the frictional force. Since the movement is prevented, there is no need to provide both a backlash spring and a spring for increasing the frictional force, and much less a large device such as a ratchet mechanism is required. Further, the biasing force of the spring 27 also functions as a stopper for the diopter dial 24, and once assembled, the diopter dial 24 is prevented from falling off, which is convenient from the viewpoint of assembly.

The interlocking portions 26b constitute cam followers, respectively.

In this case, the diopter dial 24 slightly vibrates in the axial direction with rotation due to the unevenness, and the eyepiece 17 also moves along the optical axis while finely vibrating. Although the finder image may be shaken, there is an effect that the number of parts can be further reduced.

The same components as those in FIGS. 1 to 4 are denoted by the same reference numerals. The operation member 34 includes an operation section 34a and a cam section 34.
b and a flange portion 34c, and the operation portion 34a is exposed to the outside from the slit 2a of the camera body 2. By sliding the operation portion 34a along the slit 2a, the operation member 34 can be moved in the vertical direction in FIG. 6 (in FIG. 5, the direction orthogonal to the paper). Flange part 34
A friction member 35 made of silicon rubber or the like is provided between the camera body 2 and the camera body 2, and the friction member 35 is arranged so as to be in contact with the entire outer edge of the flange portion 34c as can be seen from both figures.

Is constantly pressed into contact with the cam surface 34d. Therefore, the cam interlocking portion 36d reliably follows the movement of the cam surface 34d due to the sliding operation of the operation member 34, and adjusts the diopter by driving the holding frame 36, that is, the eyepiece 17, in the optical axis direction.
Also, the urging force of the spring 37 prevents the eyepiece 17 from undesirably moving due to vibration or the like.

As a result, the friction member 35 is pinched between the flange portion 34c and the camera body 2 and generates an appropriate friction force opposing the operation of the operation member 24. Therefore, the operation member 34 does not move due to vibration of the camera or the like, and the eyepiece 1
The change in diopter due to the undesired movement of No. 7 is prevented.
