An image reading apparatus includes a first image reading unit, a second image reading unit provided on a side opposite from the first image reading unit with respect to a sheet feeding passage, a first guiding member, a second guiding member, a first unit holding the first image reading unit and the second guiding member, and a second unit holding the second image reading unit and the first guiding member. One of the first unit and the second unit is movable relative to the other unit so as to open the sheet feeding passage.

An image-reading apparatus includes: a light-receiving unit that receives reflected light from a recording medium; a substrate that supports the light-receiving unit; an optical member that is located at a position different from a position of the substrate in a substrate thickness direction corresponding to a thickness direction of the substrate and that guides the reflected light from the recording medium to the light-receiving unit; and a supply unit that supplies cooling gas that is used to cool the substrate to the substrate. The cooling gas that is supplied to the substrate flows along the substrate.

An environment management apparatus for inside of a machine includes an estimator and a generator. The estimator estimates an environment state in the machine in a case of executing a process under a predetermined control condition, from process execution data for instructing execution of the process. The generator generates, for the environment state estimated by the estimator, a time-series scheme for environment control during the execution of the process from a calculation result obtained by calculating a control condition which maintains the environment state to be less than or equal to a predetermined target value.

An image reading apparatus includes: a light emission section including a light emitting element, and a light guiding member configured to irradiate a sheet with light emitted from the light emitting element; a reading section configured to read an image formed on the sheet; a heat dissipation section configured to dissipate heat of the light emitting element; and a cooling section configured to cool the heat dissipation section, in which the light emitting element and the heat dissipation section are disposed at positions outside a sheet passing region of the sheet in the width direction.

Provided is a photoelectric conversion device including: a photoelectric conversion element row including photoelectric conversion elements arranged in one direction which faces from one end to the other end; a substrate to which the photoelectric conversion element row is attached; a processing circuit attached to the substrate on an outer side than the one end of the photoelectric conversion element row in the one direction and configured to perform a process on output signals output from photoelectric conversion elements disposed on the one end side in the photoelectric conversion element row; and another processing circuit attached to the substrate on an outer side than the other end of the photoelectric conversion element row in the one direction and configured to perform a process on another output signals output from photoelectric conversion elements disposed on the other end side in the photoelectric conversion element row.

A digital video camera, including a heat management system, which includes at least one inlet and at least one outlet in the housing to enable air to flow through the housing. The heat management system also includes a first heat sink thermally connected to an image sensor(s), and a second heat sink thermally connected to a data processing unit(s), and a centrifugal fan. The centrifugal fan is configured to draw air into the front of the fan in an axial direction and push air radially out in a sideways direction, whereby air travels through the inlet(s) over the first heat sink and then over the second heat sink to the outlet(s).

An image forming apparatus includes an image forming unit, one or more processors, and memory storing instructions that, when executed by the one or more processors, cause the image forming apparatus to perform operations. The image forming unit forms an image on a sheet. The operations include controlling execution of dew condensation elimination processing that is processing for eliminating dew condensation having occurred in the image forming unit. The operations additionally include receiving image data to be printed and restricting, based on a type of a job executed using the received image data, image forming by the image forming unit, in a case where the dew condensation elimination processing is in execution.

An image reading device includes a light applying unit that applies light from a light source to a recording medium, a detecting unit that detects the light reflected by the recording medium, a holding member that is movable in a first scanning direction of the light applying unit and holds a calibration member to which the light from the light applying unit is applied, a shaft member that extends in the first scanning direction through the holding member and guides the movement of the holding member in the first scanning direction, and a restricting member that extends in the first scanning direction and restricts rotation of the holding member about the shaft member.

An image reading apparatus includes: a light emission section including a light emitting element, and a light guiding member configured to irradiate a sheet with light emitted from the light emitting element; a reading section configured to read an image formed on the sheet; a heat dissipation section configured to dissipate heat of the light emitting element; and a cooling section configured to cool the heat dissipation section, in which the light emitting element and the heat dissipation section are disposed at positions outside a sheet passing region of the sheet in the width direction.
