Abstract: An image position detecting device includes a light irradiating unit and a photodetector. The light irradiating unit is disposed so as to face a movable body which is being moved in a certain direction. The light irradiating unit irradiates any of marks formed on the movable body with light having a wavelength in an ultraviolet range at a time. The marks are formed of color components, respectively. The photodetector is provided separately from the light irradiating unit to face the movable body. The photodetector detects light having a wavelength in the ultraviolet range from light regularly reflected by the irradiated mark.

Abstract: The present invention provides a cooling system including: a cold air generator which supplies cold air into a case of an apparatus; a wireless temperature sensor which is provided near at least one module constituting the apparatus and sends temperature data as a radio signal; a transmitter/receiver which sends a radio signal having a predetermined frequency to the temperature sensor and receives a radio signal from the temperature sensor; and a controller which controls an operation of the cold air generator on the basis of a radio signal received by the transmitter/receiver.
