A master disk which simulates a tire and is used at the time of confirmation or correction of measurement accuracy of a geometry measuring device for measuring the surface shape of a tire, of a tire testing machine, includes: a simulated tire section simulating a tire; a lower tubular section having a cylindrical shape, in which the tip side thereof is connected to the lower end side of the simulated tire section so as to be coaxial with the simulated tire section and a guide surface inclined in a tapered shape so as to have a larger diameter toward the base end side is formed on the base end side of an inner peripheral surface; and a neck section and a flange section which are provided on the upper end side of the simulated tire section and detachably engaged with test rim moving and exchanging means of a tire holding device of the tire testing machine.

Master disk, master disk mounting method, and master disk removal method

A tire inspection device according to the present invention includes a support portion which supports a tire such that a center axis of the tire is positioned along a vertical direction, a lifting and lowering portion which moves the tire and a rim relative to each other in the vertical direction to fit the rim to the tire, a position detection unit which detects a position of a surface of the tire in the vertical direction at three or more detection points, and a posture detection unit which detects posture information of the tire based on position information detected by the position detection unit.

Tire inspection device and tire posture detection method

This tire marking apparatus is a tire marking apparatus for performing marking in a tire. The tire marking apparatus includes a disk part having a central axis that is adjusted substantially perpendicularly to a printing surface of the tire; a plurality of printing parts that are provided in the disk part so as to be capable of moving forward and backward with respect to the printing surface and are arranged around the central axis; and a printing driving unit that moves at least one printing part arranged at a printing position that faces the printing surface of the tire forward.

Tire marking apparatus

This printing device includes a first supply roller and a second supply roller that supply the pair of ink ribbons; a first winding roller and a second winding roller that are pulled out from the first supply roller and the second supply roller and wind the pair of ink ribbons passing through a printing position; and a roller driving unit that rotates the first winding roller and the second winding roller. The roller driving unit includes one rotational driving device in which a rotating shaft is rotatable in a normal direction and a reverse direction, a first transmission mechanism that transmits only the rotation of the rotating shaft in the normal direction to the first winding roller, and a second transmission mechanism that transmits only the rotation of the rotating shaft in the reverse direction to the second winding roller.
