ABSTRACT:
An original or a photosensitive film is held by a sheet holder and the sheet holder is fixed to the drum of an image reading scanner or an image recording scanner by a row of hooks planted on the drum. A row of holes corresponding to the row of hooks are formed at each of the opposing ends of the sheet holder. A hook is composed of: a stem, a lever rotatably attached with a pin to the stem, and a plate urged upward by a spring against the bottom of the lever. A plane is formed at a side of the bottom of the lever. First the levers of the hooks are raised upright and the holes of an end of the sheet holder are engaged with the hooks. After surrounding the drum with the sheet holder, the holes at the other end of the sheet holder are engaged with the hooks and the levers are turned to a lying position, where the levers are stable because the plate is urged upward against the side plane of the lever.
