PURPOSE:To make inputs from an operation panel, which is not operated with an attendant, ineffective to secure safety of the attendant by using buttons and number display devices on operation panels for customer and attendant to assign test functions. CONSTITUTION:In case that a device is tested, key signals from a customer operation panel 1 and those from an attendant operation panel 2 are inputted to an arithmetic control circuit 36 through key signal encoder circuits 33 and 34 etc. In this case, keys of the same function are set to the same code to make it unnecessary that a program of the circuit 36 divides both of them to pay attentions to them. If a door is opened by a gate circuit 37 and a rear door opening/ closing detecting mechanism 7, inputs of the customer operation panel 1 are made ineffective and are stopped. Various push buttons and number display devices on the customer operation panel and the attendant operation panel are used to assign test functions in this manner, and thereby, inputs from the panel which is not operated by the attendant are made ineffective to secure safety of the attendant. |
