The structure of the optical print head includes a flat mount having a recessed portion opening upward and forward on its upper surface, and a block fitted into the recessed portion of the mount, and the LED unit is placed in the recessed portion of the mount. At the same time as being attached to the bottom surface, the focusing rod lens array is attached in close contact with the front inner wall and the opposing side wall of the recess, and the rear end surface of the block is in close contact with the focusing rod lens array, The structure of the optical print head is characterized in that the block is fitted into the recess of the mount so that the output pattern of the circuit board is pressed into contact with the input pattern of the LED unit, thereby sealing the recess. (2) The utility model registered in claim 1 is characterized in that the joint portions of the mount and the block, the mount and the convergent rod lens array, and the block and the convergent rod lens array are sealed. structure of optical print head.
