Abstract: In an exemplary embodiment, a blade portion 41 is formed by a plurality of blades 42 being arrayed on a front surface of a main body at an even interval while forming blade striation portions 43 between adjacent blades 42. Each blade 42 is cut into a circular-arc shape. A pitch between the blades 42 is in a range of 1 to 3 mm. A recess-portion apex composed of a cut surface of each blade 42 has a rounded shape with a radius of 1.0 to 3.0 mm. A protrusion-portion apex of the blade striation portion 43 has a rounded shape with a radius of 0.1 to 0.5 mm. A tip of the blade 42 formed by the blade striation portion 43 has a rounded shape with a radius of 0.1 to 0.5 mm.

Abstract: In an embodiment, a peeling device includes: a vertical rotation disk 110 provided in a rotation shaft that extends horizontally; a plurality of fruit and vegetable holders 131 rotatably provided around a rotation axis of the vertical rotation disk 110, each supporting a fruit or vegetable K in a support portion 131C that extends from a disk surface 110A of the vertical rotation disk 110; and a peeler main body 202 that moves along an axial direction of the fruit or vegetable K in a state in which a peeler blade 202A is pressed against the fruit or vegetable K. At a peeling position, the fruit or vegetable K is rotated by the fruit and vegetable holder 131 being rotated, and full-periphery peeling by the peeler blade 202A is performed by the peeler main body 202 moving along the axial direction of the fruit or vegetable K.

Abstract: An ink ribbon cassette to be used in wire dot printer has an ink supply to lengthen a life cycle thereof. An ink ribbon is held between a drive gear and an idle gear and is delivered thereby. The ink supply contacts the idle gear so that ink is supplied from the idle gear to the ink ribbon. The teeth of the idle gear are specifically shaped such that the bottom of the teeth are formed in the shape of a circular arc so that the ink is uniformly supplied to the ink ribbon.
