    摘要： For an image sensor that is elongated in a main scanning direction, an image sensor mounting bracket is obtained that suppresses a warp of the image sensor due to the weight thereof. The image sensor mounting bracket includes a fastening element to be fastened to a lateral surface of the image sensor and a fastening element to be fastened to an attachment target object, the fastening element intersecting the image sensor-side fastening element. The fastening element has an image sensor fastening surface abutting the image sensor and having positioning pins, and the attachment target object fastening element has an attachment target object fastening surface abutting the attachment target object and having elongated through holes that elongate in a sub-scanning direction and are arranged in the main scanning direction and the sub-scanning direction.

    摘要： There are provided a line sensor (110) including two first sensor pixel rows (111a, 111b) and a second sensor pixel row (112a); an image obtaining unit (140) to obtain, from electrical signals obtained by scanning an original in a sub-scanning direction with the two first sensor pixel rows (111a, 111b), two first read image data items, and obtain, from electrical signals obtained by scanning the original in the sub-scanning direction with the second sensor pixel row (112a), a second read image data item; and an image processor (150) to incorporate one or more pixel data items of one or more pixels included in an interval between the two first sensor pixel rows (111a, 111b) out of the second read image data item into the two first read image data items, thereby generating a line image data item in which the one or more pixels in the interval are not vacant.

    摘要： An image capturing device (1) includes: a microlens array (33) including a plurality of micro condenser lenses (34) arranged at a focal position of an imaging optical system for forming a plurality of erect equal-magnification images; and an imaging unit (31) including light-sensitive pixels (32x) provided at positions corresponding to the micro condenser lenses 34. Micro condenser lenses (34) have refractive powers to condense, among light rays incident from the imaging optical system, light rays incident at an incident angle within a predetermined limited angle range, onto positions different from positions on which light rays incident at an incident angle outside the limited angle range are incident. Effective light-sensitive regions of the light-sensitive pixels (32x) receive only light rays incident at an incident angle within the limited angle range among light rays entered micro condenser lenses (32).

    摘要： An image reading device includes a lens array including lenses arranged in a main scanning direction and forming an erect unmagnified optical system to converge light from a reading target, a holder holding the lens array, a light receiver to receive the light converged by the lenses, and slit units. Each slit unit includes three or more light shielding plates each separating an optical path of one lens from an optical path of another lens between the lens array and the light receiver, and side plates disposed on two sides of the light shielding plates in a direction intersecting the main scanning direction and connecting two adjacent light shielding plates. The slit units are arranged in the main scanning direction, and each two adjacent slit units are arranged with a space therebetween for one optical path of one lens.
