A reflector for a vehicle can include a plurality of retroreflective elements configured to retroreflect incident light incident parallel to a horizontally-arranged reference axis, obliquely upward at a prescribed angle with respect to the reference axis. The plurality of retroreflective elements can each include: a first reflection surface inclined at an angle ANG1 to the reference axis; a second reflection surface inclined at an angle ANG2 to the reference axis, and formed in a position reached after the second reflection surface is rotated from the first reflection surface through an angle ROT1 around the reference axis as a center; and a third reflection surface inclined at an angle ANG3 to the reference axis and formed in a position reached after the third reflection surface is rotated from the first reflection surface through an angle ROT2 around the reference axis as a center in a direction opposite to the second reflection surface, the first to third reflection surfaces arranged so as to form corners of a substantial cube, wherein a condition of following expressions is satisfied: ANG2>ANG3; ANG2>ANG1; and ROT1>ROT2>120 degrees.

Disclosed is an image forming apparatus (1) in which a sheet (P) is fed through a conveyance passage from one wall (2a) to the other wall (2b) of a box-shaped housing (2), and the sheet (P) reversed in a reversing passage (28) near the other wall (2b) is discharged in a discharge section of a top wall (2c), and the other wall (2b) near which the reversing passage (28) is provided includes an upper portion projecting outward in the top wall (2c) and a lower portion receding inward in a bottom wall (2d) so that an area of the bottom wall (2d) is smaller than that of the top wall (2c). Therefore, a space for an installation can be reduced when the image forming apparatus (1) is disposed on a desk (40) and the like.

An object is to provide a milk foamer capable of smoothly and securely managing hygiene of a suction tube which sucks milk from a milk storage section. The milk foamer sucks the milk from a milk pack via the suction tube and mixes the milk and air with the milker to produce milk foam. The milk foamer includes a control unit which controls the production of the milk foam, and a cleaning unit which executes a cleaning operation of a route extending from the suction tube to the milker. The control unit prohibits the production of the milk foam and instructs the cleaning unit to execute the cleaning operation, in a case where a predetermined time elapses from the previous production of the milk foam.

There is provided a liquid containing bag capable of supplying mixture directly to a cooling cylinder from the bag without depending on gravity and without moving the mixture into a hopper. A liquid containing bag 5 comprises a bag main body 21 containing a liquid and having flexibility, and an outer layer member 23 disposed outside the bag main body 21, capable of forming a sealed space between the outer layer member and the bag main body 21, and having flexibility. Therefore, for example, when compressed air is sealed between the outer layer member 23 and the bag main body 21, an volume of the sealed space between them is enlarged, and the liquid cooled in the bag main body 21 can be pushed to the outside.
