A sheet collection apparatus has a stacking portion to stack mails in the standing position, a back-up plate in contact with one end of stacked mails in the stacked direction, and take-in rollers arranged at the positions contacting the other end of stacked mails. On detection of one-click rotation of the jog dial by one click at step S2 and on detection of the pushing of the jog dial at step S3, the operating mode is switched to an operating mode in meeting with the operation on the jog dial. A biasing means is operably interconnected to the reform rollers, such that the reform rollers extend to contact the inner surface of the bottom portion of the container when contacted by the bottom portion of the container. Importantly, the tiltable sheet feeding apparatus includes an overtilt safety sensor device mounted within the trail edge elevator slots and connected to the controller, for sensing overtilt of the trail edge of the sheet support tray, and for preventing resulting damage to the tiltable sheet feeding apparatus. This invention thus relates to the seeds of soybean variety XB15W06, to the plants of soybean XB15W06 to plant parts of soybean variety XB15W06 and to methods for producing a soybean plant produced by crossing plants of the soybean variety XB15W06 with another soybean plant, using XB15W06 as either the male or the female parent. The antimicrobial composite materials may include combinations of activated carbon and a biguanide hydrate.
