  • Patent number: 11813848
    Abstract: A printer includes a printer body, a hopper, an open-and-close cover, a paper support, and a support holder. The hopper pushes paper up while supporting the paper. The open-and-close cover is able to be opened from and closed toward the printer body. The paper support is provided in such a way as to be able to be housed inside and drawn away from the open-and-close cover, and is configured to support the paper by being drawn out. The support holder supports the paper, together with the hopper and the paper support. The support holder switches between an upright orientation for being housed into the printer body and a tilted orientation for supporting the paper together with the hopper and the paper support by the opening and closing of the open-and-close cover.

  • Patent number: 11449721
    Abstract: An image forming apparatus includes a plurality of print heads, a sensor, a processor, and an image forming unit. The plurality of print heads are arranged in parallel. The sensor detects a color shift amount of each color to be printed by the plurality of print heads in a main scanning direction based on an output result of a test pattern by the plurality of print heads. The processor sets a color shift correction value for correcting the color shift amount on the basis of a color having a largest color shift amount. The processor controls light emission of the plurality of print heads based on the color shift correction value and image data. The image forming unit forms an image based on the image data on a sheet by light emission of the plurality of print heads.

  • Publication number: 20210295920
    Abstract: A semiconductor storage device according to the present embodiment includes a plurality of memory cell arrays, a plurality of block selectors, and a controller. The memory cell arrays each include a plurality of subblocks connected to each other via common word lines, and include memory cells at respective intersections between the word lines and bit lines provided in each subblock. The block selectors each include switching elements connected to bit lines in a corresponding one of the subblocks at one ends and to a corresponding sense amplifier at the other ends. The controller maintains, in a case where data is read out from one subblock in a same memory cell array and thereafter data is read out from another subblock in the same memory cell array, switching elements in a block selector corresponding to the one subblock in a conductive state.
