照）。The operation button 32 is formed by a pair of leaf spring portions 44 and 45 which extend substantially parallel to the short side of the operated surface 32e (direction substantially orthogonal to the longitudinal direction) and contact the bottom surface 32f.
The operated surface 32e is pressed in a direction of protruding from the camera body 11. The leaf spring portions 44 and 45 have a substantially symmetrical shape with the switch pressing protrusion 32b interposed therebetween.
45, a continuous portion with the frame portion 41 serving as each fulcrum, the leaf spring portion 4
Contact portions (points of action / points of force) where 4, 45 act on the bottom surface 32f of the operation button 32 are also formed substantially symmetrically with the switch pressing protrusion 32b interposed therebetween (see FIG. 1). The operation button 32 is attached to the free end of each of the leaf springs 44 and 45.
Is bent in a protruding direction, and engaging portions 44a and 45a are formed to prevent the tilting or shifting of the operation button 32 by engaging the side surface of the flange portion 32a (see FIGS. 2 and 4).

The escape grooves 32c and 32d become deeper toward the connecting direction of the frame portions 41 of the leaf spring portions 44 and 45 from the approximate center of the bottom surface 32f of the operation button 32, the position intersecting with the center line c in FIGS. The plate spring portions 44 and 45 are inclined and formed so as not to come into contact with each other. By these escape grooves 32c and 32d,
Since the leaf spring portions 44 and 45 make line contact with the bottom surface 32f of the operation button 32, the ridge line that is the boundary between the escape grooves 32c and 32d and the bottom surface 32f, and the longitudinal direction of the operation button 32 at the center line c position, The fluctuation of the contact position and the fluctuation of the action direction are reduced.

The flange portion 32a is pressed against the small-diameter edge portion 152a of the button guide hole 152 by the biasing forces of Nos. 4 and 45, and is held in this state. In this standby state, the leaf springs 44 and 45 are each about 1 / th of the width direction of the bottom surface 32f of the operation button 32.
Since it is in contact with the area of No. 2, the operation button 32 can be stably held in the standby state.

While being bent, the tip end of the switch pressing protrusion 32b contacts the switch contact piece 23, and the switch contact piece 23 is short-circuited to turn on the switch (FIGS. 3 and 5). When the operation button 32 is moved, the escape grooves 32c and 32d and the bottom surface 32f are provided.
Since the leaf spring portions 44 and 45 come into contact with the boundary edge portion of the operation button 32, the operation button 32 is biased by the leaf spring portions 44 and 45 substantially in the center line c direction, and moves in parallel to the center line c direction. Operation button 32
When the external force for pressing is removed, the operation button 32
The elastic restoring forces of 4 and 45 push in the protruding direction parallel to the center line c, and the flange portion 32a is pressed and held in a standby state in which the flange portion 32a is in contact with the small diameter edge portion 152a.

る。As described above, when the operation button 32 is pushed and protruded, the leaf spring portions 44 and 45 are provided with the escape grooves 32c and
Since the ridge line that serves as the boundary between 32d and the flat bottom surface 32f makes contact, even if the operation button 32 moves in the direction of the center line c, the action directions of the leaf spring portions 44 and 45 remain substantially parallel to the center line c. Since the operation button 32 is maintained, the operation button 32 hardly moves and tilts during the movement, and the operation button 32 can be stably moved and a reliable switch operation can be performed.
