Abstract
The invention relates to a coin validator comprising a string sensor, which is arranged in the area of the coin insertion channel, and comprising a coin validating device for controlling the acceptance or rejection of an inserted coin. The string sensor comprises a first tooth, which is placed on a stationary part of the coin insertion channel, a second tooth, which is placed on a pendulum and which is disengaged when a coin is inserted, and comprises a switching device, which is actively connected to the pendulum and which furnishes a signal to the coin validating device when a coin is inserted. The pendulum is a component of a coin insertion funnel that, as a wearing part, is detachably connected to the housing of the coin validator and forms a part of the coin insertion channel. The pivot point of the pendulum coupled to the remaining part of the coin insertion funnel is, when viewing the cross-section, laterally offset with regard to the first and second tooth in such a manner that when the second tooth moves, in the direction of insertion of the coin downward in an arc-like manner, it disengages from the first tooth or when the second tooth moves upward in an arc-like manner, it engages with the first tooth.
