Abstract:
An exposing unit includes a holding member, an abutting pin protruding on both sides in the vertical direction at the rear side of the holding member, a second support portion provided further to the rear side than the holding member, and a movement mechanism that causes the holding member to move between an exposure position and a retracted position. The second support portion has a gap formed where the rear side of the holding member moves in the vertical direction, and this gap restricts movement of the holding member in the left-and-right direction. The holding member that is moved from the retracted position toward the exposure position by the movement mechanism is guided by the gap formed in the second support portion so that the abutting pin abuts a fitting portion.

Claim (Index 1):
An image forming apparatus having a drum unit rotatably supporting a photosensitive drum, the image forming apparatus comprising:\n an optical print head configured to expose the photosensitive drum; a movement mechanism configured to reciprocally move the optical print head between an exposure position where the photosensitive drum is exposed, and a retracted position that is further retracted from the drum unit than the exposure position; an abutting pin that is formed protruding from one end side of the optical print head in the longitudinal direction of the optical print head, in a direction toward the drum unit side in the direction of the reciprocal movement and a direction opposite to the drum unit side, and that is configured to abut an abutting portion formed on one end side of the drum unit in the longitudinal direction and to position the optical print head at the exposure position; a first facing portion that is provided facing both sides of the abutting pin in a perpendicular direction perpendicular to both the longitudinal direction and direction of reciprocal movement, at the opposite side of the optical print head as to the side where the drum unit is disposed, and that is configured to come into contact with the abutting pin in the perpendicular direction, to restrict movement of the abutting pin in the perpendicular direction; and a second facing portion that is provided facing both sides of the optical print head in the perpendicular direction, and that comes into contact with the optical print head in the perpendicular direction, to restrict movement of the optical print head moving from the retracted position toward the exposure position and also to move the optical print head in the direction of reciprocal movement, wherein the abutting pin is guided to move toward the abutting portion by the first facing portion and the second facing portion, due to movement of the abutting pin in the perpendicular direction being restricted by the first facing portion and movement of the optical print head in the perpendicular direction being restricted by the second facing portion, and the optical print head being moved from the retracted position toward the exposure position by the movement mechanism is positioned at the exposure position.
