A prewhirl type inlet casing for inducing a spiral stream in fluid has a suction passage arranged on an upstream side, being orthogonal to a rotary shaft of fluid machinery, and an internal passage connected to the suction passage, the internal passage being formed in a spiral shape so as to induce a swirl stream orthogonal to the rotary shaft in the fluid. A guide vane provided in the fluid passage in the inlet casing has a rectifying function capable of distributing flow rates in the swirl stream of the fluid in the internal passage between the swirl center side and the swirl outer peripheral side, and causing the fluid to deflect into the swirling direction of the swirl stream induced by the internal passage.

A prewhirl type inlet casing for inducing a spiral stream in fluid comprising a suction passage arranged on an upstream side, being orthogonal to a rotary shaft of fluid machinery, and an internal passage connected to the suction passage, the internal passage being formed in a spiral shape so as to induce a swirl stream orthogonal to the rotary shaft in the fluid. A guide vane is provided in the fluid passage in the inlet casing. The guide vane has a rectifying function capable of distributing flow rates in the swirl stream of the fluid in the internal passage between the swirl center side and the swirl outer peripheral side and has a rectifying function capable of causing the fluid to deflect into the swirling direction of the swirl stream induced by the internal passage. With these rectifying functions, a rectified swirl stream can be easily created in the in internal passage so as to prevent occurrence of a deviation of a cavitations inducing zone. With this configuration, it is possible to effectively prevent occurrence of the deviation of the cavitations inducing zone in order to aim at simplifying the configuration of the internal passage.

A transport device includes a set section, a sheet sensor, and a feeding member. When a detection member does not retract, the sheet sensor outputs an OFF-detection signal. The feeding member is displaced between a feed position and a non-feed position on the basis of the detection signal. At the feed position, the feeding member comes in contact with the sheet set in the set section from above and feeds the sheet toward the downstream side on a transport path. At the non-feed position, the feeding member is separated upward from the feed position. A method, which detects a sheet in the transport device, includes displacing the feeding member from the non-feed position to the feed position, and detecting that the sheet does not exist in the set section when an OFF-detection signal is output from the sheet sensor while the feeding member is positioned at the feed position.

A plate-shaped main body, has a first face formed with a recess portion defined by a bottom face and side walls and a second face which is opposite to the first face. The plate-shaped main body is formed with a through hole connecting the bottom face and the second face. An overhanging portion, is provided on at least one of the side walls in the vicinity of the first face, and is located so as to at least partially hang over the through hole.

A printing apparatus that is a vertical installation type apparatus having a height direction dimension that is larger than at least one of a width direction dimension and a length direction dimension when the printing apparatus is installed, includes an ink cartridge that can be attached to and detached from a printing apparatus body, and an attachment section to which the ink cartridge is attached. The ink cartridge can be attached to and detached from the attachment section from a top surface side of the printing apparatus. The thus-structured printing apparatus allows a user to easily reach the attachment section for the ink cartridge regardless of which face of the printing apparatus is facing the user.
