  • Publication number: 20190296044
    Abstract: According to an embodiment, a semiconductor memory device includes a substrate, a stacked body and a columnar portion. The columnar portion is provided inside the stacked body and includes a semiconductor portion extending in a first direction. The columnar portion has widths having mutually-different sizes in a second direction perpendicular to the first direction. The widths include first and second widths. The first width is a width of the columnar portion positioned inside a first electrode film of lowermost layer of the electrode films. The first width is substantially the same width at positions in the first direction of the columnar portion. The second width is a width of the columnar portion positioned inside a second electrode film of the electrode films. The second width is substantially the same width at positions in the first direction of the columnar portion. The first width is smaller than the second width.

  • Patent number: 9725265
    Abstract: Provided are a floating restricting member restricting the floating position of a bundle of sheets; and a holding mechanism holding the floating restricting member relative to a side fence. The floating restricting member includes a sheet contact section being brought into contact with the sheets from above; and a sheet-floating restricting section restricting the floating position of the floating sheet that is floated while air is blown thereto. The holding mechanism sets the floating restricting member in the initial state where the sheet-floating restricting section restricts the floating position of the sheet, in the sheet-placing time retracted state where the sheets are pushed against the sheet contact section so that the floating restricting member is retracted, and in the sheet-ejecting time retracted state where, when the sheets are to be removed, the sheet is pushed against the sheet contact section from below so that the floating restricting member is retracted.
