Abstract

An information processing apparatus includes a memory that stores object information and spatial information. The object information is information on an object to move in a space. The spatial information is information on the space and includes at least three-dimensional information of the space. The information processing apparatus includes an input device that receives movement condition information indicating a condition for movement of the object. The movement condition information includes at least information on a start point and an end point of the movement of the object. The information processing apparatus includes an information processor that generates route-related information including information on the movement of the object in the space based on the object information, the spatial information, and the movement condition information.

Abstract

A heating device includes a rotator, a heater, a holder, a temperature sensor, and a thermal conductor. The heater faces an inner face of the rotator, extends in a longitudinal direction, and includes a base and a heat generator having a main heat generation region. The temperature sensor inside the rotator faces one end of the main heat generation region and includes a terminal. The thermal conductor on the heater extends in the longitudinal direction, has a high thermal conductivity, and includes a main portion having a first cross-sectional area, an arm having a second cross-sectional area smaller than the first cross-sectional area, and a projection. The arm extends from one end of the main portion closer to the temperature sensor than another end of the main portion. The projection projects from one end of the arm and is separated from the terminal by an insulation distance or more.
