And an interlocking drive mechanism 88 that drives the shutter plate 29 from the open position to the close position in conjunction with the pressing operation. The interlock drive mechanism 88 is provided between the operation member 41 and the shutter plate 29. Provided.

この実施の形態で前記連動駆動機構８８は、前記操作部材４１に一体に設けられる押圧部４５に前記操作部材４１の他端側（カバー部材３１とは反対側）に臨むようにして形成される押圧カム面８９と、前記シャッター板２９に一体に設けられる受圧部５０に前記押圧カム面８９に対向するようにして形成される受圧カム面９０とで構成される。   In this embodiment, the interlock driving mechanism 88 is formed by a pressing cam 45 formed integrally with the operating member 41 so as to face the other end side (opposite to the cover member 31) of the operating member 41. And a pressure receiving cam surface 90 formed so as to face the pressing cam surface 89 in a pressure receiving portion 50 provided integrally with the shutter plate 29.

前記押圧カム面８９は、前記シャッター板２９の回動方向３２で閉じ位置側に進むにつれて前記操作部材４１の一端側（カバー部材３１側）に位置するようにして螺旋状に形成されるものであり、前記受圧カム面９０も前記押圧カム面８９に対応して螺旋状に形成され、前記シャッター板２９が前記開き位置にある状態では、図９で示すように前記押圧カム面８９および前記受圧カム面９０は相互に当接もしくは近接対向している。   The pressing cam surface 89 is formed in a spiral shape so as to be positioned at one end side (the cover member 31 side) of the operation member 41 as the shutter plate 29 moves toward the closed position side in the rotation direction 32. The pressure receiving cam surface 90 is also formed in a spiral shape corresponding to the pressing cam surface 89, and in the state where the shutter plate 29 is in the open position, as shown in FIG. The cam surfaces 90 are in contact with or in close proximity to each other.

このような連動駆動機構８８では、シャッター板２９が開き位置にある状態で前記操作部材４１を押圧操作するのに応じて、図１０で示すように、前記押圧カム面８９からの押圧力が前記受圧カム面５０に作用して前記シャッター板２９が閉じ位置側に回動駆動されることになる。   In such an interlocking drive mechanism 88, as shown in FIG. 10, the pressing force from the pressing cam surface 89 is applied to the operating member 41 in a state where the shutter plate 29 is in the open position. Acting on the pressure receiving cam surface 50, the shutter plate 29 is rotationally driven to the closed position side.

ところで前記シャッター板２９が前記開き位置から前記閉じ位置に回動する際に、前記シャッター板２９の前記突部２９ｃは、規制位置側に向けて第３ばね５７で付勢された前記規制部材５６の規制突部５６ｄを乗り越えるものであり、その際の乗り越え作動を円滑とするために、前記規制突部５６ｄの前記カバー部材３１側に臨む面の前記回動方向３２に沿う少なくとも開き位置側の部分には、前記開き位置側に向かうにつれて前記カバー部材３１から遠くなるように傾斜した傾斜面９１が形成され、前記突部２９ｃの前記カバー部材３１とは反対側に臨む面には、前記傾斜面９１に対応して前記開き位置側に向かうにつれて前記カバー部材３１から遠くなるように傾斜した傾斜面９２が形成される。   By the way, when the shutter plate 29 rotates from the open position to the closed position, the protrusion 29c of the shutter plate 29 is urged by the third spring 57 toward the restriction position side. In order to make the climbing operation smooth at that time, at least the opening position side along the rotation direction 32 of the surface facing the cover member 31 side of the regulation projection 56d. In the portion, an inclined surface 91 is formed so as to be farther from the cover member 31 toward the opening position side, and the inclined surface 91 is formed on a surface facing the opposite side of the cover member 31 of the protrusion 29c. An inclined surface 92 is formed so as to be farther from the cover member 31 toward the opening position corresponding to the surface 91.

次にこの実施の形態の作用について説明すると、メカニカルキー挿入孔２７へのメカニカルキー１４の挿入方向と平行な方向に押圧操作することを可能とした操作部材４１が、少なくともシャッター板２９を開き位置とした状態、この実施の形態では前記シャッター板２９の作動位置にかかわらずでケーシング２８におけるカバー部材３１の外面から前記操作部材４１の一端部を突出させるようにして前記ケーシング２８に支承され、前記シャッター板２９を前記操作部材４１の前記押圧操作に連動させて前記開き位置から前記閉じ位置に駆動する連動駆動機構８８が、前記操作部材４１および前記シャッター板２９間に設けられるので、開き位置に在る前記シャッター板２９を閉じ位置側に動かすときには、ケーシング２８の外面から一端部を突出させている操作部材４１を押し込み操作すればよく、ケーシング２８に、従来のような円弧状の開口部を設ける必要がなく、ケーシング２８のデザイン上の自由度が増大し、しかも操作部材４１の外周およびケーシング２８間のシールだけを考慮すればよいので防塵、防水構造上も有利となる。   Next, the operation of this embodiment will be described. An operation member 41 that can be pressed in a direction parallel to the insertion direction of the mechanical key 14 into the mechanical key insertion hole 27 opens at least the shutter plate 29. In this embodiment, regardless of the operating position of the shutter plate 29, the operation member 41 is supported by the casing 28 so that one end of the operation member 41 protrudes from the outer surface of the cover member 31 in the casing 28. Since an interlocking drive mechanism 88 that drives the shutter plate 29 from the open position to the closed position in conjunction with the pressing operation of the operation member 41 is provided between the operation member 41 and the shutter plate 29, the shutter plate 29 is in the open position. When the existing shutter plate 29 is moved to the closed position side, one end from the outer surface of the casing 28 is It is only necessary to push in the operating member 41 that protrudes, and it is not necessary to provide the casing 28 with an arcuate opening as in the conventional case, the degree of freedom in design of the casing 28 increases, and the operating member 41 Since only the seal between the outer periphery and the casing 28 has to be taken into consideration, it is advantageous in terms of dust and water resistance.
