Problems solved by technology

Therefore, it has been considered, for example, to set a radiator with a large cooling fin, or to use a high-output fan to form a large amount of air flow to improve the heat dissipation effect. Larger size may lead to larger and higher cost of the exposure unit and pattern forming device, so it cannot be said to be the best strategy

Embodiment Construction

[0017] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] figure 1 is a perspective view showing the appearance of the image forming apparatus 1 of the present invention, figure 2 It is a sectional view showing the internal structure of the image forming apparatus 1 . refer to figure 1 and figure 2 , the configuration of the image forming apparatus 1 will be described. The image forming apparatus 1 is exemplified as a full-color copier. In addition, in the figure, in order to clarify the orientation relationship, the orientation of the image forming apparatus 1 is shown based on the standing position of the operator during use. Therefore, in the following description, the image forming apparatus 1 will be described based on this orientation.

[0019] The image forming apparatus 1 of the present embodiment includes an apparatus main body 2 . The device main body 2 has a substantially rec...

Abstract

An image forming device (1) includes an exposure device (an exposure unit (YM) and an exposure unit (CB)) configured to emit exposure light and an air flow generator (an air blowing fan (38)) configured to generate an air flow. The exposure device includes a heat source (a polygon motor (58) and / or a driver IC (59)) that generates heat and a heat sink (72) configured to dissipate the heat. The heat sink (72) includes a plurality of fins (74) located inside the air flow. The plurality of fins (74) extend in a direction parallel to a direction where the air flow flows and are arrayed in a direction orthogonal to the direction where the air flow flows. The plurality of fins (74) are formed so as to increase in height from an upstream side toward a downstream side in the direction where the air flow flows.

Description

technical field [0001] The present invention relates to an image forming apparatus such as a copying machine, a printer, a facsimile machine, or a multifunction machine thereof, and particularly to an image forming apparatus including an exposure device. Background technique [0002] An exposure unit (exposure device) is provided in an image forming apparatus such as a copier. The exposure unit irradiates laser light on the surface of the photosensitive drum to form an electrostatic latent image. The exposure unit includes optical components such as a light source for emitting laser light, a lens for forming an image of the emitted laser light, a polygon mirror for deflecting the laser light, a motor for rotating and driving the polygon mirror, and a case for accommodating these components. [0003] Since the motor (polygon mirror motor) becomes a heat source in the exposure unit, in order to continuously perform stable exposure, it is necessary to release the heat generate...
