The half.-ratescanning system shown includes mirrors 12, 13 and reciprocating carriages 21, 22. The photoreceptor 23 and the carriage assembly 21, 22 are driven from a motor 20 through an endless cable or chain which passes over a drive pulley 2 and a pulley 3 mounted for rotation with the photoreceptor. The photoreceptor is driven through the pulley 3 and carriage assembly is driven through a pawl mechanism 5. The pawl 5 is pivotally mounted on the full rate carriage 21 and is arranged to be engaged by detents 6 equally spaced
