The invention relates to the security arrangements provided for the cash box for use in call coin box equipment and has particularly been designed for use in the new generation micro-processor controlled call coin box equipment. The cash box is provided with a lockable lid having a coin entry slot (4) and a coin entry shutter mechanism. The coin entry shutter mechanism co-operates with a pair of mounting pins (6A, 6B) in the coin box housing in such manner that removing the cash box from the mounting pins causes the shutter (3,4) to be automatically closed and locked over the coin entry slot (4). The authorised opening of the cash box primes the shutter mechanism ready for replacement on the mounting pins (6A, 6B) without opening the coin entry slot (4). Finally replacement of the cash box on the mounting pins causes the operating of the shutter mechanism to uncover the coin entry slot. |
