摘要:
An electronic circuit having an electronic component mounted on a substrate, a light source device having the electronic circuit, and a method of manufacturing the electronic circuit on which the electronic component is mounted on the substrate are described. The electronic component has a plurality of lead pins to be electrically connected to wirings on the substrate. The substrate is formed with a hole having a larger dimension than a maximum distance between at least two lead pins of the lead pins. The lead pins are inserted into the hole from sides of tips of the lead pins while being bent at a plurality of bending portions, and fixed to the substrate by a solder.

An optical scanning device includes a light source emitting light to form an image by optical scanning; and a control section generating a control signal, which is for turning on and off the light source, based on an image signal. Further, the control section generates a pulse signal having a redetermined time width when the image signal indicates that the light source is to be turned off.

A scanner includes: an acquiring unit that acquires determination result information based on a determination result of whether a target dot of a target pixel of a plurality of pixels constituting image data is a first dot or a second dot; a light source control unit that, if the target dot is the first dot, causes a light source to emit a light beam during a corrected lighting time with a light source characteristic time based on a characteristic of the light source being added to a predetermined lighting time that is preliminarily determined with respect to the target dot, and if the target dot is the second dot, causes the light source to emit a light beam during the predetermined lighting time; and a deflecting unit that deflects the light beam in the main scanning direction.

An image forming apparatus includes a photoconductor, a light source, an optical scanning device, an image bearer, an image density sensor, an image processing circuit, and a light source driver. The plurality of images are formed with a plurality of light intensities and a plurality of image area rates on the image bearer. The image density sensor detects a plurality of image densities of the plurality of images at a plurality of positions in a main scanning direction. The image processing circuit determines a light intensity correction value to correct an image density of a target image in the main scanning direction based on the plurality of light intensities, image area rates, image densities, and positions, and the image area rate of the target image, and outputs a control signal to adjust a light intensity. The light source driver adjusts the light intensity based on the control signal.
