Abstract
In a recording apparatus comprising a recording head with a multiplicity of individually addressable and energizable point-like radiation sources arranged in staggered parallel rows for irradiating points across a moving photoreceptor, the driver circuits for the different rows of radiation sources are provided by identical chips. Each chip incorporates delay means capable of holding data-bit signals for a delay period before the signals are transmitted for energizing the associated radiation sources but is formed so that the delay means can be rendered inoperative by selecting one or other of different mode control voltage input points. The control chips for one row of the radiation sources are set in the delay-operative mode to compensate for the distance between the two rows of sources.
