<p>A coin validator comprising a coin receiving slot (2) opening into a coin guide path (5), an obturator (11) downstream of the slot normally blocking the passage of all coins inserted therein until it is moved out of the coin path when coin validating means (9,10), preferably two pairs of orthogonally arranged coils, upstream of the obturator senses that the true coin has been received in the slot, the obturator being operable to return and represent all unacceptable coins at the coin receiving slot. Additional sensors such as photosensors (30, 31) may also be provided and operably linked with the obturator so that it is only moved out of the coin path when various signals generated thereby satisfy a pre-set security sequence. <IMAGE></p> |
