摘要： A light scanning device includes: a first semiconductor laser 44a that emits a light beam L1; a polygonal mirror 42 that deflects the light beam L1; a reflective mirror 64a that reflects the light beam L1 deflected by the polygonal mirror 42 and causes the light beam L1 to enter a photosensitive drum 13; and a BD sensor 72 that detects the light beam L1 deflected by the polygonal mirror 42. The light scanning device scans the photosensitive drum 13 with the light beam L1 and set scanning timing of the photosensitive drum 13 using the light beam L1 based on detection timing of the light beam L1 using the BD sensor 72. The BD sensor 72 is arranged in the position farther from the polygonal mirror 42 than the last reflective mirror 64a that reflects the light beam L1 immediately before entering the photosensitive drum 13 and arranged inside a scanning angle range α of the light beam L1 corresponding to an effective scan area of the photosensitive drum 13.

摘要： An image reading device includes a first image reading portion, a cooling portion, a second image reading portion, and a notification processing portion. The first image reading portion reads an image of a document sheet at a first reading position. The cooling portion cools the document sheet at a cooling position downstream in a feeding direction of the document sheet with respect to the first reading position. The second image reading portion reads an image of the document sheet at a second reading position downstream in the feeding direction with respect to the cooling position. In a case where a difference image different from a first image read by the first image reading portion, the difference image being included in a second image read by the second image reading portion has been detected, the notification processing portion provides a notification that the difference image has been detected.

摘要： A hand-held scanning system and method thereof are described. A look-up table is created to generate a mapping relation between a plurality of reference amplitudes and a plurality of corresponding sampled positions. An analog-to-digital converter samples an analog signal and converts it into a digital signal. The digital signal represents a mapping relation between the sampled positions of the movement distance and the corresponding scanning amplitudes of the signal intensity. The hand-held scanning system ascertains the sampled positions corresponding to a former scanning amplitudes and a present scanning amplitudes according to the look-up table during the scanning stage for detecting the position variation status to determine whether the trigger signal is activated for image scanning or not.

摘要： An optical scanning apparatus includes a housing, light source, deflector, imaging lens, reflective mirrors, a synchronization detector and synchronization detection mirror. The housing has a plate to partition the housing. The deflector deflects a light beam emitted from the light source. The imaging lens converts the deflected light beam into a constant speed scanning light beam. The reflective mirrors reflect the constant speed scanning light beam to a photoreceptor. The synchronization detector detects timing for starting scanning of the photoreceptor. The synchronization detection mirror reflects the light beam to the synchronization detector. At least one of the reflective mirrors is disposed midway in a synchronization detection light path extending from the deflector to the synchronization detection mirror. The light beam reflected by the synchronization detection mirror is reflected again by at least one of the reflective mirrors, such that the light beam is guided to the synchronization detector.
