A non-transitory, computer-readable recording medium having stored therein a program for causing a computer to execute a process that includes: obtaining a heat generation amount of a component via an interface; calculating a unit heat-generation amount using the heat-generation amount of a component, and a unit size that is one of a volume of the component and a surface area of the component, the unit heat-generation amount being the heat-generation amount per the unit size; determining whether the unit heat-generation amount is greater than a threshold value; and causing an output device to output a signal for indicating that consideration of heat dissipation measures is desired for the component for which the unit heat-generation amount is determined to be greater than the threshold value.

An image pickup apparatus with forced air-cooling structure, which is capable of improving heat radiating efficiency. The image pickup apparatus comprises a fan, an inlet, an outlet, and a duct, which has an inhaling part interconnecting with the inlet, a discharging part interconnecting with the outlet, and a cooling part connected to each of the inhaling part and the discharging part. Each of the inhaling part and the discharging part is connected to the cooling part in a direction intersecting with the cooling part.

An image reading apparatus capable of detecting correct color tones of an image printed on a sheet is described. The image reading apparatus includes a scanner 100, a colorimeter 103, a cooling device 145, a temperature control unit 111, and an image correction unit 113. While an image correction process is not performed, the temperature control unit 111 controls the cooling temperature to a first temperature for shifting the cooling device 145 to a predetermined cooled state. While the image correction process is performed, the temperature control unit 111 controls the cooling temperature to a second temperature for making the temperature of the sheet uniform. The image correction unit 113 obtains, while the temperature control unit 111 controls the cooling temperature to the second temperature, the correction amount of the image based on the colorimetric measurement result of the colorimeter 103 and the reading result of the scanner 100.

A blast mechanism in an image reading apparatus reliably cools heat generated in boards by a blast path with high cooling action among a plurality of boards disposed inside a casing. A partition plate is disposed between a plurality of boards disposed at a distance away in a layered shape, a first blast path is formed between a top of the casing and a first board, a second blast path is formed between the first board and the partition plate, a third blast path is formed between the partition plate and a second board, and a flow of cooling air is formed in each blast path with a blast fan. A blast mechanism for sending cooling air includes the casing, first and second boards disposed vertically inside the casing, the partition plate disposed between the first board and the second board, and fans for sending cooling air.

The scanning optical device (6) includes a light source, a deflector (30) configured to rotate on a horizontal surface around a rotating shaft extending in a vertical direction and an optical box (50) in which the light source, the deflector (30), and the optical components groups (40) are housed and supported by the frame (60). A heat sink (36) is disposed between the deflector (30) and the frame (60). A first protrusion (37) extending on an extension line of the rotating shaft of the deflector (30) is formed in the heat sink (36). A first engaging hole (61) with which the first protrusion (37) engages is formed in the frame (60).
