In recent years, in response to demands for production adjustment of semiconductor packages and high-mix low-volume production, resin encapsulation devices that can be increased or decreased by modularizing a press section have been developed and put into practical use. For this reason, when increasing the production amount of the semiconductor package, the loader 10 is supplied from the molded article supply section.
7, there is a demand for a loading operation for loading a substrate or a resin tablet into the press unit 108 at high speed. Therefore, it is necessary to quickly supply the substrate and the resin tablet to the loader 107.

In the case of the resin tablet supply device shown in FIG. 6, the resin tablets t supplied from the tablet delivery section 102 are once held by the hands P and Q, respectively, until they are loaded into the holding holes 105 of the tablet holder 104. Therefore, it takes time to supply the resin tablet t because the holding operation by a plurality of hands is involved. Further, if the transfer path of the resin tablet t is changed by changing the apparatus layout, a complicated operation is required for the hand, and it takes time. In addition, while the tablet holder 104 transfers the resin tablet t to the loader 107, the feeding operation of the resin tablet t is stopped from the tablet sending unit 102, so that a waiting time is generated and the efficient supply of the resin tablet t is performed. Can not do. Further, an inspection stage 103 is provided to inspect the quality / defectiveness of the resin tablet t, and if the resin tablet t is defective, it is held by the hand Q and discharged to the tablet discharge unit 106.
The tablet transfer operation takes time because the transfer path is different depending on the defect. When the press unit 108 is increased from one press to two presses, the delivery cycle T of the resin tablet t shown in FIG. 7 is appropriately adjusted to T → T ′ (T <T ′) to supply the resin tablet t. If the number of pots is small, the operation can be completed in a short time. However, when the press unit 108 is additionally provided with three presses or four presses, the value of the delivery cycle T becomes short, and the supply of the resin tablet t follows. Press part 1 due to machine cycle delay
08 will be difficult to increase.
