Abstract: To ensure that a biodegradable medical implement dissolves in vivo at an appropriate dissolution rate. The biodegradable medical implement of the present invention is formed of a magnesium material, and, at least in one transverse section, a layer of magnesium crystal grains in which a (0001) plane in a hexagonal crystal structure is oriented toward a surface side is continuous over an entire circumference.

Abstract: An image reading apparatus includes a scanner unit configured to read a document, a document feed unit provided above the scanner unit and configured to feed the document and read the fed document, a first substrate configured to control an operation of the scanner unit, and a second substrate configured to control an operation of the document feed unit, wherein the first substrate and the second substrate are provided in a substrate placement section of the document feed unit.

Abstract: A printing apparatus includes an apparatus main body that houses the printing unit therein, and that includes a paper feeding port provided on the upper surface; an upper feeding path configured to guide the medium fed from the paper feeding port and including a first curved portion in a middle portion thereof for inverting the medium; a medium housing portion configured to house the medium; and a lower feeding path configured to guide the medium from the medium housing portion and including a second curved portion in a middle portion thereof for inverting the medium in a course of the guidance, in which an innermost portion of the first curved portion overlaps the second curved portion in a depth direction from the front surface toward a rear surface, which is on a side opposite to the front surface, of the apparatus main body when viewed from the upper surface.

Abstract: A printing apparatus includes a printing unit that performs printing on a medium, an apparatus main body that houses the printing unit therein and that has outer surfaces including an upper surface and a front surface that adjoiningly intersects the upper surface, a paper feed port that is provided on the upper surface of the apparatus main body and that enables the medium to be fed into the apparatus main body, a feed path that is guiding the medium fed from the paper feed port toward the printing unit and that has a curved portion for inverting the medium during the guiding, a pair of rollers that are provided at the upstream of the curved portion and that feed the medium toward the printing unit via the feed path by rotating while nipping the medium fed from the paper feed port from both front and rear sides.

Abstract: A printing device includes a print section. A main unit, which has a supply port via which the medium is to be inserted on its upper surface. The medium inserted via the supply port is to be guided to the print section along an upper feeding route. This upper feeding route has a first curve at its midway point. Positioned below the main unit is a medium storage section that accommodates a medium. The medium accommodated in the medium storage section is to be guided to the print section along a lower feeding route. This lower feeding route has a second curve at its midway point, where the medium is to be turned around. The main unit includes: a first cover that allows the upper feeding route to be exposed; and a second cover that allows the lower feeding route to be exposed.
