Abstract:
1. A processing apparatus including a processing unit which processes an object, the apparatus comprising: a first conveyer configured to hold the object with a first hand included therein and to perform conveyance of the object between the processing unit and a station arranged between an external apparatus, which is separate from the processing apparatus, and the processing unit, the external apparatus including: (a) a second conveyer configured to hold the object with a second hand included therein and to perform conveyance of the object to the station or from the station, and (b) a second controller configured to control the conveyance by the second conveyer; and a first controller configured to output a request signal and a stop instruction signal to the second controller, wherein the request signal is a signal for requesting the external apparatus to perform the conveyance by the second conveyer, and is output before the first hand reaches a first position, where a collision of the first hand or the object held by the first hand with the second hand or the object held by the second hand can be avoided, from a second position where the collision cannot be avoided, the processing apparatus comprising an interface via which a preset time is changeable, the first controller outputting the request signal at the preset time before an estimated time for the first hand to reach the first position, and wherein the stop instruction signal is a signal which instructs the external apparatus to stop the second hand, the first controller being configured to output the stop instruction signal, if it is determined, based on a state of the processing apparatus after an output of the request signal, that the collision may occur because the first hand is at the second position.
