PURPOSE:To make possible high-density printing by connecting an LED array element to a driver for driving the element in a simple process to realize their high-density packing design at an LED printer head. CONSTITUTION:LED array elements 5 and drivers for driving the elements 4 are mounted on a mount board 6, and a lens array for optical condensation 1 is arranged. The same number of metal patterns 3 as that of electrodes for the LED array elements 5 and drivers 4 are formed on the lens array frame 2 of the lens array 1, and the lens array frame is pressed so that the metal pattern is positioned between both electrodes. Thus both electrodes are electrically connected. |
