    • A coin acceptor produces an output or operates a switch or vending mechanism when a coin acceptor slide reaches a certain point of advance relative to a housing. The slide receives coins or tokens tendered by a customer (“coins”) and carries the coins into a discriminator responsive to size, shape or the like. The discriminator can have feeler levers, a limited passage size or similar features that permit the slide to advance if all the correct coins are present, or obstruct movement of the slide if coins are missing or are the wrong type. The discriminator is breakable with sufficient force, which could break away the feeler levers or other test structures the obstruct movement unless the correct coins are in place, which would permit the slide to be operated repeatedly without the correct coins. According to an inventive aspect, a latch mechanism engages if the slide is forced beyond its normal operating span, for example because it is forced, and locks the slide in an advanced position where it remains until serviced. The limit of the normal operating span can be defined by a frangible abutment that breaks away under moderate force. In any event, the slide locks in an advanced position and cannot be operated repeatedly without the correct coinage.
    • 当硬币接收器滑块相对于壳体达到某个提前点时,硬币接收器产生输出或操作开关或自动售货机构。 幻灯片接收客户投标的硬币或令牌(“硬币”),并根据尺寸,形状等将硬币运送到鉴别器中。 鉴别器可以具有触觉杠杆,有限的通道尺寸或类似的特征,如果所有正确的硬币存在,允许滑块前进,或者如果硬币丢失或错误的类型,则妨碍滑块的移动。 鉴别器具有足够的力可破坏,这可以将探测器杆或其他测试结构的阻挡运动分开,除非正确的硬币就位,这将允许滑块在没有正确硬币的情况下重复操作。 根据本发明的一个方面,如果滑块被迫超过其正常操作跨度,例如由于其被迫而将滑块锁定在其保持的前进位置直到被维修,则闩锁机构接合。 正常操作范围的极限可以由在中等强度下分解的易碎基台定义。 无论如何,滑块锁定在高级位置,不能在没有正确造币的情况下重复操作。
