Abstract: A heating cooker includes a cooking chamber accommodating an object to be cooked, a hot air generator and a blower. Hot air generated by the generator impinges as a high-speed impinging jet on the object from a nozzle hole located in a ceiling plate. The hot air having impinged on the object is drawn our through hot-air suction openings located in lower parts of right and left sidewalls of the chamber by the blower. A shelf plate is located in the chamber so that the object is placed on it. The shelf plate has openings on right and left sides. Hot air is caused to impinge on the object through the nozzle hole. The shelf has a convex portion formed on a face on which the object is to be placed which supports the object from below.

Abstract: A sampling apparatus automatically samples a small number of printed sheets from a conveyance path which is formed by two opposed conveyance members constituting the conveyance path and through which folded printed sheets are conveyed in a line and overlap each other at a certain pitch. The sampled printed sheets are taken out from the conveyance path through an opening portion formed in one of the conveyance members. The apparatus includes a sample plate. The sampling plate reciprocates linearly between a wait position and an advanced position. When the sampling plate is advanced, the sampling plate traverse a conveyance path zone corresponding to the opening portion and reaches the opening portion, while maintaining a posture in which the sampling plate is substantially parallel to the printed sheets line.
