PURPOSE: To simply perform the work detaching the surface of a letterpress stamp from a wood base and the work attaching the same to the wood base in a stamp forming unit capable of forming a desired letterpress stamp by exposing and curing a plate-shaped photosensitive resin. CONSTITUTION: A stamp forming unit 1 is constituted of a printing member 3 equipped with a photosensitive resin plate 33 and a wood base 2 and the printing member 3 and the wood base 2 are connected by magnetic attraction force. A pair of positioning circular holes 34, 35 are formed to the attaching surface of the printing member 3 and a pair of the positioning circular projections 24, 25 capable of being inserted in the circular holes 34, 35 are formed to the wood base 2 and the printing member 3 can be simply separated from the wood base 2. When the corresponding projections and holes are matched at the time of connection, the printing member and the wood base are automatically connected in an aligned state by the magnetic force generated therebetween. As a result, the attaching work of the wood base and the printing member becomes extremely simple. |
