A portable copier system including an upper panel having a device groove and a camera slot, an object sensor for measuring an object size and detecting presence or absence of an object, a lower panel fitted with a plurality of guides, wherein each of the plurality of guides is attached with an object sensor, an adjustment mechanism comprising a plurality of extendible rods, wherein each of the plurality of extendible rods is connected to the upper panel and supported by the lower panel, an image capture device mounted on the device groove, and a controller that controls the adjustment mechanism based on data from the object sensor data and sends signal to the image capture device.

An image reading apparatus includes an image reading part that reads an image formed on a recording medium, an accommodating unit that accommodates the image reading part and supports the image reading part in such a manner that the image reading part is capable of being displaced toward a side on which the recording medium is to be disposed, and an urging member that urges, in the accommodating unit, the image reading part toward the side on which the recording medium is to be disposed. The accommodating unit includes an urging-member-mounting portion in which the urging member is mounted, and at least one window is formed in the urging-member-mounting portion on a side opposite to a side on which the image reading part is disposed.

A reading device includes: a light source to emit light to a subject; an imaging device to receive light reflected from the subject and generate an image; a first inclination correction device to mechanically correct an inclination of the subject; a second inclination correction device to electronically correct an inclination of the image obtained at the imaging device; and circuitry to: switch to use between the first inclination correction device and the second inclination correction device. In a case where the subject includes subjects of a single size but does not include subjects of multiple sizes, the circuitry switches to use the first inclination correction device, and in a case where the subject includes subjects of multiple sizes, the circuitry switches to use the second inclination correction device.
