Substantially formed in plan view in the spring member 54 of M shapes by bending wire, and be provided with four fulcrum portion 55 and a biased sections 56.Four fulcrum portion 55 are set as resting upon the side band part 22 of the both sides of base component 2 Inner surface on.In this condition, the angle of elevation θ and length L of biased sections 56 are set such that the bias of spring member 54 Part 56 will be in contact with the bottom surface of supporting member 51, so as to upward (towards the rear side of base body 21) biasing support component 51 Another side portion.

When assembling binder 1, first bend the side band part 22 half of base component 2.In this condition, will switch Control unit 4 is inserted and is arranged on base component 2 from the rear side of base body 21.Next, by the right side, left support component 51, 52 configurations in the rear side of base body 21, make positioned at the side portion of right, left support component 51,52 inner side lap each other Covering.That is, configured in the tab 51b of supporting member 51 on tab receptacle 52c in supporting member 52 and supporting member 52 Tab 52b configure on the tab receptacle 51c of supporting member 51 in the state of, supporting member 51,52 is able to configure in base The rear side of portion's body 21.So, half ring element 31,32 for being attached to supporting member 51,52 is directed into base portion by slit 28 The top of body 21.Then, in this condition, the side band part 22 of base component 2 bends.Then, by across in side band Spring member 54 is installed between part 22.Thereby, it is possible to assemble the binder 1 shown in Fig. 1.

Next, the operation detail by multiple parts during the ring 3 for describing opening and closing binder 1.Figure 21 and figure 23 show the state of critical piece when ring 3 is in open mode, and when Figure 22 and Figure 24 show that ring 3 is in closure state Critical piece state.According to present embodiment, supporting member 51,52 is always by spring member 54 along making the first semi-ring structure The direction that part 31 and the second half ring elements 32 are separated from each other biases.

First, the operation that makes ring 3 be switched to from open mode closure state will be described.As shown in Fig. 1 and Fig. 3 to Fig. 4, When ring 3 is in open mode, the end section 30 of the first half ring elements 31 and the second half ring elements 32 is separated from each other.

When ring 3 is in open mode, switch control unit 4 is maintained at the second state, and as shown in Figure 21, second The abutting end 421 of control unit 42 is held against the bottom land 23a of the second groove part 232.When supporting for the second control unit 42 Connect end 421 against the second groove part 232 bottom land 23a when, rotation of the switch control unit 4 along second direction D2 is limited System.

In addition, in this condition, the first cam portion 432a of cam body 43 keep keeping out of the way be arranged at supporting member 51, Keeping out of the way in hole 53 in 52, and thus keep separating with supporting member 51,52 (abutment portion 51d, 52d).In addition, in the state Under, the second cam portion 432b of cam body 43 is against inclined surface 51f, 52f.Therefore, when the second cam part of cam body 43 When point 432b is biased via supporting member 51,52 by spring member 54, tend to rotate switch control unit 4 along second direction D2 Power act on switch control unit 4.This makes it possible to suppress the not inadvertently D1 rotations along a first direction of switch control unit 4 Turn, and switch control unit 4 is maintained at the second state.So, due to the second control unit 42 abutting end 421 against The bottom land 23a of second groove part 232, waved so can suitably suppress switch control unit 4.

Further, since the second control unit 42 abuts end 421 and the second groove part 232 in base component 2 Bottom land 23a is flat surfaces, so can be in the state of abutting end 421 and being configured to contact with bottom land 23a generations surface, will Switch control unit 4 is maintained at the second state.This causes switch control unit 4 to be maintained at the second shape in switch control unit 4 More it is difficult to wave during state.Specifically, according to present embodiment, when switch control unit 4 is in the second state, the second control The lateral end of unit 42 processed is supported by being contained in the second groove part 232.This to make even in torsion etc. When firmly not inadvertently acting on switch control unit 4, can also suppress cam body 43 camshaft 431 be applied in it is excessive Active force, suitably suppress camshaft 431 and sustain damage, and switch control unit 4 is more difficult to wave.

Next, the operation that makes ring 3 be switched to from open mode closure state will be described.As described above, in binder 1 In, the supporting member 51,52 of support ring 3 includes：Abutment portion 51d, 52d, it is in the first cam portion with cam body 43 Ring 3 is placed in closure state when 432a is abutted；With keep out of the way hole 53, its formed near abutment portion 51d, 52d, and suitable for First cam portion 432a keeps out of the way is placed in open mode when keeping out of the way in hole 53 by ring 3.

Lower thrust F1 is applied to the pressing surface 412 of the first control unit 41 of switch control unit 4 by user.This Sample, when lower thrust F1 exceedes the biasing force of spring member 54, the first cam portion 432a of cam body 43 departs from supporting member 51st, keep out of the way hole 53 in 52, and slided along inclined surface 51f, 52f (referring to Figure 22).Then, the first cam of cam body 43 Part 432a crosses inclined surface 51f, 52f, and the abutment portion 51d of the first cam portion 432a and supporting member 51,52, 52d is abutted.When abutment portion 51d, 52d of supporting member 51,52 abut with the first cam portion 432a, positioned at supporting member 51st, the lateral end of 52 inner side is pressed downwardly by the use of bent portion 29 as fulcrum.Thus, the first semi-ring structure of ring 3 The end section 30 of part 31 and the second half ring elements 32 is against each other, so as to which ring 3 is configured in closure state.So, due to moving back Keep away hole 53 to be arranged near abutment portion 51d, 52d of supporting member 51,52, therefore the first cam portion 432a can be rapidly Against abutment portion 51d, 52d.This operates the operational ton (first needed for switch control unit 4 when making it possible to reduce close ring 3 The volume under pressure of control unit 41).

Binder 1 is designed such as only when the first half ring elements 31 of ring 3 and the end section of the second half ring elements 32 30 by it is against each other to close when, the abutting end 411 of the first control unit 41 of switch control unit 4 will be with the first groove The bottom land 23a of part 231 is abutted.That is, in the bottom land for abutting the groove part 231 of end 411 and first of the first control unit 41 When 23a is abutted, switch control unit 4 is switched to first state and ring 3 is in closure state.

Here, the bottom land for abutting the first groove part 231 in end 411 and base component 2 of the first control unit 41 23a is flat surfaces.Therefore, it is configured to contact with bottom land 23a generations surface in the abutting end 411 of the first control unit 41 In the state of, switch control unit 4 can be maintained at first state.This makes it possible to be maintained at the first shape in switch control unit 4 Suitably suppress switch control unit 4 during state to wave.Specifically, for the binder 1 according to present embodiment, When switch control unit 4 is in first state, the lateral end of the first control unit 41 is contained in the first groove part 231 In, so as to by bottom land 23a and a pair of internal groove side wall 23b supports.This, which not inadvertently to act on even in active forces such as torsion, cuts When changing in control unit 4, the camshaft 431 that can also suppress cam body 43 is applied in excessive active force, and suitably presses down Camshaft 431 processed sustains damage.Waved furthermore it is possible to suitably suppress switch control unit 4.

Next, the operation that makes ring 3 be switched to from closure state open mode will be described.Cut when making ring 3 from closure state When changing to open mode, lower thrust F2 is applied to the pressing surface of the second control unit 42 of switch control unit 4 by user 422.Therefore, inclined surface 51f, 52f along supporting member 51,52 of the first cam portion 432a of cam body 43 slide and Keep out of the way in hole 53.Therefore, the abutting between the first cam portion 432a and abutment portion 51d, 52d is released, and The inner side edge of supporting member 51,52 is pressed upwards on by the biasing force of spring member 54.Thus, the first semi-ring structure of two rings 3 The associated end part 30 of part 31 and the second half ring elements 32 is separated from each other, so as to which ring 3 is configured in open mode.Here, by It is configured in abutment portion 51d, 52d of supporting member 51,52 close to keeping out of the way hole 53, therefore can rapidly discharges the first cam Part 432a and the abutting of abutment portion 51d, 52d.
