engagement pin

34,35 is arranged on apparatus main body 12, and lever arm 61 is along with moving the operation of operation knob 62, thus both ends (65a, the 67) engaging that supplies lever arm 61.

Operation knob 62 is arranged on the central authorities of the length direction of lever arm 61.And along with the operation of operation knob 62, lever arm 61 moves along its length.

Fig. 7 is the exploded perspective view of lever arm 61, operation panel 63 and operation knob 62, and Fig. 8 is its assembly drawing.

In Fig. 7 and Fig. 8, lever arm 61 has: the rectangular box-like frame 65 with first end 65a; Below (Z direction) with respect to this frame 65 Fig. 7 has the flat part 66 that stage portion is also flatly extended; And the second end 67 that has small stage portion and flatly extend from the top (Z direction) of this flat part 66 to figure.

Like this, when 22 pairs of battery chambers 26 of battery cover were sealed, lever arm 61 moved to Fig. 7 right-hand (directions X), and first end 65a engages with the engagement pin 35 of apparatus main body 12, and simultaneously, the second end 67 engages with engagement pin 34.

In addition, erect at the flat part 66 of lever arm 61 and be provided with operative pin 68.On the other hand, on operation panel 63, be formed with through hole 69.Operation panel 63 is installed on the operative pin 68 of lever arm 61 through this through hole 69.

This through hole 69 forms eccentric with respect to the center of operation panel 63.Therefore, the operative pin 68 of intercalation in this through hole 69 also installed with respect to the center of operation panel 63 prejudicially.Thus, when making operation knob 62 rotations, lever arm 61 moves along its length.

In addition, on operation panel 63, except through hole 69, also be formed with a plurality of (being 4 among the figure) through hole 70.Operation panel 63 utilizes this through hole 70 to combine with operation knob 62, is mounted with non-rotary mode.

Lever arm 61 is retained as and can moves with respect to battery cover 22 broad wayss (directions X of Fig. 5 and Fig. 6).But lever arm 61 can not move along thickness direction (the Z direction of Fig. 5) with respect to battery cover 22.Like this, when operation knob 62 was rotated, lever arm 61 moved along its length and engages with

engagement pin

34,35.

In addition, anti-deformation metalwork 58 shown in Figure 8 is the metalworks that are used to prevent that the second end 67 of lever arm 61 from deforming because of fatigue etc.This is to be out of shape because of the second end 67 that external force acts on lever arm 61 through long-term use in order to prevent.

In addition, in this execution mode, the situation that covers distolateral (the second end 67) of lever arm 61 through anti-deformation metalwork 58 is illustrated, but is not limited thereto.For example, also can cover the both end sides (first end 65a and the second end 67) of lever arm 61 through same metalwork.

Thus, can prevent to act on the first end 65a of lever arm 61 respectively and the second end 67 makes lever arm 61 each end distortion because of external force.

Fig. 9 is the vertical view when inner surface side is observed battery cover 22.

In Fig. 9, when the arrow B direction was carried out rotating operation, lever arm 61 moved along the arrow C direction to operation knob 62.Thus, the first end 65a of lever arm 61 and the second end 67 with engagement pin 34,35 (with reference to Fig. 3) thus engage the locking battery cover 22.

In addition, when operation knob 62 was carried out rotating operation round about, lever arm 61 moved to the direction opposite with arrow C, and the locking of battery cover 22 is disengaged.

Figure 10 A and Figure 10 B are the figure of the operate condition of expression lever arm 61.

Figure 10 A representes the latch-release state of lever arm 61 with respect to engagement pin 34,35 (with reference to Fig. 3), and Figure 10 B representes the lock-out state of lever arm 61 with respect to

engagement pin

34,35.

Shown in Figure 10 A, under the latch-release state of lever arm 61, lever arm 61 does not engage with

engagement pin

34,35.

That is, under this state, the first end 65a of lever arm 61 and the second end 67 are positioned at respect to engagement pin 34,35 (directions X) position of leaving along its length.This is the only state of the peristome 26a of clad battery chamber 26 of battery cover 22, and not locking.

Then, shown in Figure 10 B, when operation knob 62 is rotated, through operation panel 63 and operative pin 68 make lever arm 61 along its length (arrow C direction) move.

In addition, the rotation of this operation knob 62 is actually operation knob 62 is rotated.

Like this, lever arm 61 (directions X) along its length moves, and the upper surface of its first end 65a and the second end 67 (the A face of Figure 10 A, A ' face) enters into the downside (Z direction) of

engagement pin

34,35 and engages.Thus, lever arm 61 becomes lock-out state with

engagement pin

34,35.

Through this engaging, the peristome 26a of battery cover closing battery chambers 26 22 shown in Figure 4.In addition, the end of first end 65a and the second end 67 can form the conical surface, to engage with

engagement pin

34,35 easily.

In addition, in this execution mode, the first end 65a of lever arm 61 and the upper surface of the second end 67 (the A face of Figure 10 A, A ' face) are positioned at the position of leaning on top (the Z direction of Figure 10 A) than the lowest surface of

engagement pin

34,35 slightly.

Thus, under first end 65a and the second end 67 and state that

engagement pin

34,35 engages, lever arm 61 (and battery cover 22) because of the reaction force of

engagement pin

34,35 slightly downwards (arrow D direction) move.

Through moving of this lever arm 61 downwards (arrow D direction), the battery cover 22 that keeps this lever arm 61 is by in apparatus main body 12 side compressions.Thus, encapsulation part 48 be pressed in battery chamber 26 around wall 30 on and keep water resistance.Under this situation,, then can further improve water resistance if encapsulation part 48 has elasticity.

In addition, in this execution mode, used the rounded metallic rod in cross section as

engagement pin

34,35, but be not limited thereto, can also be polygon, ellipse or semicircle for for example cross section.Thus, when lever arm 61 engages with

engagement pin

34,35, lever arm 61 with the bight butt of

engagement pin

34,35 easily downwards (arrow D direction) move.

Like this, in this execution mode, the operation knob 62 of the central authorities through rotating battery cover 22 moves lever arm 61 along its length, thus can make this lever arm 61 and apparatus main body 12 Width about two

engagement pins

34,35 of holding engage.

In addition, in this execution mode, lever arm 61 can move and not be fixed on apparatus main body 12 or the battery cover 22.Therefore, even mistake such as falls at apparatus main body 12, also be difficult for lever arm 61 is directly impacted.Therefore, lever arm 61 keeps the lock-out state of battery cover 22 and can not be out of shape.Like this, owing to battery cover 22 can not break away from, so can keep the water-proof function of battery chamber 26 always.

In addition; Operation knob 62 is operated and lever arm 61 is moved; With state that two

engagement pins

34,35 of apparatus main body 12 engage under, the end of lever arm 61 (for example the second end 67) are covered by the anti-deformation metalwork that on stiffener 46, forms 58 and are protected.Thus, even long-term the use also can prevent the second end 67 distortion bending of apparatus main body 12 sides (for example to) of lever arm 61.

In addition, battery cover 22 is installed in 12 last times of apparatus main body, battery cover 22 is pasted the peristome 26a that is put in battery chamber 26, make the slid underneath of this battery cover 22 to length direction (the Y direction of Fig. 3).Like this, the

claw

40,41 with battery cover 22 is embedded in claw installation portion 36, after 37, operation knob 62 is operated.Thus, the peristome 26a of battery cover closing battery chambers 26 22, and, engage with the

engagement pin

34,35 of two positions and be locked.

In addition, at this moment, because the

projection

56,57 of stiffener 46 also is embedded in the wall 30 of peristome 26a, so the installation strength of battery cover 22 is enhanced.

According to this execution mode; Locking mechanism 60 has lever arm 61, operation knob 62 and is arranged on the

engagement pin

34,35 of apparatus main body 12; When lever arm 61 engages with

engagement pin

34,35; Because battery cover 22 is pressed to apparatus main body 12 thrusters by the reaction force from

engagement pin

34,35, so can guarantee the water proofing property of battery chamber 26.

In addition; According to this execution mode; Apparatus main body 12 is made up of the elastomeric material of synthetic resin etc. and since the encapsulation part 48 of battery cover 22 be connected to battery chamber 26 around wall 30 and be urged, so by the peristome 26a of closing battery chamber, battery cover 22 ground very close to each other 26.Thereby, can guarantee to encapsulate pressure to keep the water proofing property of battery chamber 26.

In addition, according to this execution mode, because lever arm 61 is not fixed on apparatus main body 12 or the battery cover 22, so even mistake such as falls at device, lever arm 61 self is not vulnerable to direct impact yet.Thus, lever arm 61 is difficult for removing with engaging of

engagement pin

34,35, and battery chamber 26 is protected and can not exposes.
