also: パントグラフ
pantograph
Refers to the device on electric trains that collects power from overhead wires, or to a mechanical linkage used for copying drawings at scale.
When the train's pantograph separates from the overhead wire, sparks can sometimes fly.
I used a drafting pantograph to enlarge and copy the map.
The driver raised the pantograph before departure.
They lowered the pantograph for inspection.
The pantograph broke down due to strong winds, and the train stopped.
