Further, when the staple juxtaposed body 2 is removed, the return slide blocking portion 4 is pushed in and elastically deformed to release contact with the rear end portion of the staple juxtaposed body 2, and in this state, the staple juxtaposed body 2 is released. Then, the staple juxtaposed body 2 can be removed from the opening 1a and opened by passing the engaging portion 3 through the recess 2c.
本実施例は上述のように構成したから、本実施例の製造に際して、ステープル並設体２の整列並設部２ａにステープル50を並設し、この状態でステープル並設体２を本体10の裏面側に設けられた凹部１に嵌合装着し、凹部１の開口部１ａを閉塞する（図４，５，６参照）。
Since the present embodiment is configured as described above, when manufacturing the present embodiment, the staples 50 are juxtaposed in the aligned juxtaposed portion 2a of the staple juxtaposed body 2, and the staple juxtaposed body 2 is attached to the main body 10 in this state. The concave portion 1 provided on the back side is fitted and mounted to close the opening 1a of the concave portion 1 (see FIGS. 4, 5, and 6).
この際、例えばステープル50の配設状況が劣悪であると確認された場合、ステープル並設体２を取り外してステープル50を適正な状態に直すことができる。
At this time, for example, when it is confirmed that the arrangement state of the staple 50 is inferior, the staple juxtaposed body 2 can be removed to restore the staple 50 to an appropriate state.
また、本実施例は、凹部１の開口縁には係止部３が設けられ、また、ステープル並設体２の基板縁には係止部３と係止して該ステープル並設体２により凹部１を閉塞する被係止部２ｂが設けられているから、凹部１を閉塞するステープル並設体２を確実に保持することができ、しかも、簡易構造故に製造コストが安くなる。
Further, in this embodiment, a locking portion 3 is provided at the opening edge of the concave portion 1, and the locking edge 3 is locked to the substrate edge of the staple juxtaposed body 2 by the staple juxtaposing body 2. Since the locked portion 2b that closes the recess 1 is provided, the staple juxtaposed body 2 that closes the recess 1 can be reliably held, and the manufacturing cost is reduced because of the simple structure.
また、本実施例は、被係止部２ｂと係止部３との係止は、ステープル並設体２を本体10に対して前方へスライドさせることにより係止するものであるから、組み立てが簡易に行われる。
Further, in this embodiment, the locked portion 2b and the locking portion 3 are locked by sliding the staple juxtaposed body 2 forward relative to the main body 10, so that the assembly is possible. It is done simply.
また、本実施例は、被係止部２ｂと係止部３との係止により、ステープル並設体２が凹部１の開口部１ａを閉塞した場合において、ステープル並設体２の後端部に当接して該ステープル並設体２が戻り方向へスライドすることを阻止する戻りスライド阻止部４が凹部１に設けられているから、この点においても組み立てが簡易に行われる。
Further, in this embodiment, when the staple juxtaposed body 2 closes the opening 1a of the concave portion 1 by the latching between the latched portion 2b and the latching portion 3, the rear end portion of the staple juxtaposed body 2 is provided. Since the concave slide 1 is provided with the return slide blocking portion 4 that contacts the tape and prevents the staple juxtaposed body 2 from sliding in the return direction, the assembly can be easily performed also in this respect.
また、本実施例は、戻りスライド阻止部４は、弾性変形した後に復帰動してステープル並設体２の基端部を押圧するように構成されているから、ステープル並設体２の開閉が極めて簡易且つ迅速に行えることになる。
Further, in this embodiment, the return slide preventing portion 4 is configured to return after elastic deformation and press the proximal end portion of the staple juxtaposed body 2, so that the staple juxtaposed body 2 can be opened and closed. This is extremely simple and quick.
尚、本発明は、本実施例に限られるものではなく、各構成要件の具体的構成は適宜設計し得るものである。
Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
