Abstract:
1. A pattern forming device comprising: a mask holding part which holds a mask for forming a pattern; a table part on which a pattern forming specimen is placed, the table part being capable of moving the specimen upwardly and downwardly thus making the specimen approach or retract from the mask held by the mask holding portion; a paste discharge part having a discharge mechanism which forms a pattern made of a paste on the specimen placed on the table part through the mask; and a discharge mechanism drive part which moves the discharge mechanism of the paste discharge part back and forth along the mask, wherein the paste discharge part includes a pair of discharge mechanisms, the pair of discharge mechanisms is mounted in an oppositely facing manner, a concave portion is formed on the discharge mechanism on a side contributing to the formation of the pattern out of the pair of discharge mechanisms mounted in an oppositely facing manner in front of a position where the discharge mechanism is brought into contact with the mask when the pair of discharge mechanisms is brought into pressure contact with the mask in a moving direction at the time of forming the pattern, the concave portion is formed such that an edge portion of the concave portion on a side opposite to an edge portion of the concave portion which is brought into contact with the mask projects toward a side of the mask and a gap is formed between the edge portion and the mask, and the paste discharge part includes a paste supply mechanism for supplying the paste between the pair of discharge mechanisms.
