Next, the structure of the changeover switch 32c will be described in detail.

FIG. 7 is a drawing that best illustrates the characteristics of the changeover switch 32c. In this figure, reference numeral 101 denotes an operation member, which the user slides to operate when switching modes. Reference numeral 102 denotes a hole from which the unlocking pressing member projects. Reference numeral 103 (in the above description, 43 (FIG. 6)) is a lower cover of the camera, 104 is a pressing portion for unlocking, 105 is a claw portion for locking, and 106 is a pressing portion 1.
04 and a plate spring portion that supports the claw portion 105. In this embodiment, the pressing portion 104, the claw portion 105, and the plate spring portion 106 are AB.
It is unitized by integral molding with a material such as S resin.
This is referred to as a slide lock member 107. Further, the member 107 is connected to the operation member 101 via the lower cover 103.
The operation member 101 is prevented from coming off by fitting the claw leg 112 into the notch 113.

Reference numeral 108 denotes an engagement portion of the slide switch knob 110, which is also integrated with 107. 109
Is a slide switch body. Reference numeral 111 denotes a lock groove with which the locking claw 105 is engaged.

Next, the operation of the mode change switch will be described. FIGS. 8A, 8B, and 8C are detailed longitudinal sectional views of the mechanism in each mode.

FIG. 8A shows a state in which the mode is the OFF mode in FIG. 7, and the leaf spring portion 106 is in an initial state. At this time, the claw portion 105 is engaged with the lock groove 111. FIG. 7B shows the unlocking pressing portion 104.
5 shows a state in which the operation member 101 is pressed left without pressing the button downward. FIG. 9 shows the relationship between the reaction forces at this time.
(A) and (b), where P is a force pressing the operation member 101;
R1 is the reaction force that the claw portion 105 receives from the side wall of the lock groove 111 by pressing the operation member 101, R1x is the horizontal component of R1, R1y is the vertical component of R1, and this vertical component is Let it go. M1 is a bending moment generated at the fixed end of the leaf spring portion 106.

In the state shown in FIGS. 9A and 9B, the hole 1
02, there is a gap S between the pressing portion 104 and the reaction force, because the width n of the pressing portion 104 is much shorter than the length of the leaf spring portion 106, the thickness h of the leaf spring portion 106 is small. ,
Assuming that the width b, the length 1, the longitudinal section modulus is E, and the amount of deflection at the free end is δ1,

[0044]

[Outside 1] M ₁ = R _1y · l...

When the operating member 101 is pushed in the direction shown in FIG. 8B, the reaction force R1 increases and R1y also increases. In the equation, since all except for the deflection δ1 are constants, δ1 increases as R1y increases,
The lock claws 105 come off the lock grooves 111. This causes a problem that the power switch is inadvertently turned on in a bag or the like, and the battery power is reduced at the time of the most important shooting, for example. If the spring pressure is strengthened to prevent this, the force for pressing the pressing portion at the time of unlocking increases, and the usability deteriorates. In addition, since the leaf spring of the mold has a low allowable stress, simply increasing the spring pressure causes problems such as settling and breakage.

Accordingly, the present embodiment is different from the embodiment shown in FIGS.
As described above, the reaction force R3 is generated by causing the side wall of the pressing portion 104 to hit the side wall of the hole 102 before the lock claw portion 105 comes off. At this time, R2
Is a reaction force that the claw portion 105 receives from the side wall of the lock groove 111 by pressing the operation member 101, R2x is a horizontal component of R2, and R2y is a vertical component of R2. R3 is a reaction force that the pressing portion 104 receives from the side wall of the hole portion 102, R3x is a horizontal component, and R3y is a vertical component. M2 is a bending moment generated at the fixed end of the leaf spring portion 106. Considering the above, the relationship of the reaction force is as follows: R2y = R3y... Here, as can be seen from FIGS. 9 (c) and 9 (d), since l1> l2..., R2y · l1−R3y · l2 <0, the claw portion 105 is prevented from coming off the lock groove 111. it can.

FIG. 8C shows a state in which the mode lock is released. At this time, when the leaf spring portion 106 presses the pressing portion 104, as shown in FIG. 8C, a substantially S-shaped deformation occurs, whereby the claw portion 105 comes off the lock groove 111, and the lock is released. Is done. When the slide is performed while the release state is maintained, the engagement portion 108 presses the slide switch knob 110 to switch the mode.

Next, FIG. 10 shows a state in which the operating member 101 is pushed in the opposite direction to the above-mentioned example, that is, rightward without releasing the lock.

R4 is a reaction force that the claw portion 105 receives from the side wall of the lock groove 111 when the operation member 101 is pressed. P4 is the force by which the retaining leg 112 pushes the slide lock member 107 when the user pushes the operation member 101 rightward. R4 is the reaction force generated by this,
M4 is a bending moment generated at the fixed end of the leaf spring portion 106. Therefore, in this state, no vertical component is generated in R4, and the leaf spring portion 106 does not bend. Therefore, the lock does not come off. When the lock release operation is officially performed, the lock is released in the same state as in FIG. 8C, and the mode is switched by pushing the operation member 101 rightward.

In the above embodiment, a lock is provided at the center. Other embodiments include (1) a lock that can be operated only when pressed in one direction, (2) a two-mode switching only, It can also be applied to In the case of (1), as shown in FIG. 11, one side of the claw portion 134 is inclined so that the claw escapes, so that only one side is locked. In the case of (2), this is made possible by eliminating one of the grooves for moving the slide member in the previous embodiment.

As described above, before the locking claw is disengaged from the locking groove, the locking release member or a part of the locking claw abuts against the operating member. By using a structure in which the locked state is maintained by using a force, it is possible to provide a switching mechanism with reduced manufacturing cost and occupied space without losing the reliability of the lock.
