An optical device includes: a lens member including a plurality of lenses arranged such that optical axes of the lenses are substantially parallel to one another; and a plurality of column parts that are each provided along the optical axis of each lens among the plurality of lenses and each allow light to pass through inside, each column part having an outer periphery through which light is less likely to pass from inside to outside the column part than through an end portion of the column part in a direction along the optical axis, the plurality of column parts being integrally formed and disposed to face the lens member.

Optical device, image reading device, and image forming apparatus

An optical device includes: a lens body having multiple lenses arranged such that optical axes thereof are parallel to one another; a light-shielding wall that is disposed for the lens body and blocks, in an optical axis direction, portion of light directed to the multiple lenses; and a sheet member that covers a surface of the light-shielding wall, the surface being perpendicular to the optical axes, and allows light to pass therethrough.

Optical device, image reading device, and imaging forming apparatus

An image processing device includes a reception unit and a setting unit. The reception unit receives an input image signal, and a synchronization signal used to generate an output image signal on a basis of the input image signal. The setting unit sets, after the reception unit receives the synchronization signal, a reception prohibition period that prohibits reception of a different synchronization signal by the reception unit.

An image processing device includes a reception unit that receives an input image signal, and a synchronization signal used to generate an output image signal on a basis of the input image signal. In a case in which, after receiving the synchronization signal, the reception unit does not receive a next synchronization signal within a predetermined reception period, the reception unit conducts an automatic reception process that treats the next synchronization signal as being received.

Image processing device and non-transitory computer-readable medium

An image processing device includes a reception unit and a generation unit. The reception unit receives an input image signal, and a synchronization signal used to generate an output image signal on a basis of the input image signal. The generation unit generates, in a case in which the reception unit receives an initial synchronization signal of a unit of image reading, a synchronization signal for a subsequent input image signal. The reception unit receives the synchronization signal generated by the generation unit.

Image processing device and non-transitory recording medium

An image processing device includes a reception unit and a recognition unit. The reception unit receives an input image signal and a synchronization signal including a signal pattern. In a case in which the signal pattern corresponds to a predetermined prescribed pattern, the recognition unit recognizes the synchronization signal as a genuine synchronization signal to be used to generate an output image signal on a basis of the input image signal.

A noise suppressing device includes a first circuit board not being grounded; a second circuit board connected to the first circuit board through a transmission line including a signal line that transmits a high-frequency signal and a ground line, the second circuit board including a ground layer being grounded; and a high-frequency reducing element that is arranged between the ground layer of the second circuit board and the ground line of the transmission line and that reduces a high-frequency signal excited at the ground line of the transmission line.
