Claim Text:
1. A screen printing apparatus, comprising: a print executing part placed between a substrate loading position and a substrate unloading position aligned in a specific direction, the printing executing part being configured to perform screen printing on a substrate using a screen mask; a transferring and holding device configured to receive a substrate at a specific position that is defined at a standby space defined at a substrate loading position side which is closer to the substrate loading position than a print executing position at which the print executing part enables printing on the substrate, the transferring and holding device being configured to transfer the substrate to the print executing position, and the transferring and holding device being further configured to hold the substrate during the printing; a transferring device configured to transfer the substrate loaded from the substrate loading position to the specific position and causing the substrate to standby, the transferring device also being configured to receive a printed substrate from the transferring and holding device, and the transferring device being further configured to transfer the printed substrate to the substrate unloading position; a substrate imaging device being configured to image the substrate held by the transferring and holding device before printing is performed by the print executing part; and a control unit configured to control the transferring and holding device and the transferring device, the transferring and holding device being configured to receive the substrate at the specific position, and the transferring and holding device being configured to transfer the substrate from the specific position to the print executing position upon holding the substrate in advance in a state such that the substrate is printable by the print executing part, the substrate imaging device being disposed at a position where the substrate imaging device enables imaging of the substrate in the course of the transfer of the substrate from the specific position to the print executing position by the transferring and holding device, and the control unit controlling the transferring and holding device so that the transferring and holding device moves to the specific position and the transferring and holding device holds a subsequent substrate after the transferring and holding device delivers a printed preceding substrate to the transferring device, and the transferring and holding device transferring the subsequent substrate to the print executing position, and the control unit also controlling the transferring device so that the subsequent substrate reaches the specific position after the delivery of the preceding substrate and before the transferring and holding device reaches the specific position, and the control unit further controlling the transferring device so that the preceding substrate is transferred more downstream than the print executing position before the subsequent substrate is transferred by the transferring and holding device and reaches the print executing position.
