Abstract
An image head in which storage time is shortened to ease block selection. The image head is provided with means for preventing the influence of storage time. For instance, minority carriers in the switching transistors for driving image blocks are extracted by amplification circuits. Another method is to drive the switching transistors in the non-saturation region to prevent accumulation of minority carriers. The image head is provided with block selection circuit comprising a shift register and a clock counter. The datum is set in the head data set bit of the shift register at the time of resetting. Whenever the clock counter counts clock signals for one image block, the counter will shift the datum by one bit. This datum drives the image blocks.
