A printing apparatus includes a rotating shaft that is displaceable in an axial direction and feeds a recording medium by rotating, a print head that prints on the recording medium that is fed from the rotating shaft, a support member that supports the recording medium between the rotating shaft and the print head, a process execution unit that performs a front surface modifying process on the recording medium supported by the support member, and a displacement mechanism that displaces the support member according to displacement of the rotating shaft.

Printing apparatus and printing method

A developer cartridge, including: a container for containing developer; a shutter that is supported so that the shutter can linearly move relative to the container, and that opens and closes by moving linearly; a handle member that is supported so that the handle member can rotationally move relative to the container, and that includes a handle; and a conversion mechanism by which rotational-movement force that rotationally moves the handle member is converted into linear-movement force that linearly moves the shutter.

Developer cartridge, image forming apparatus, and shutter device

There are provided a platen on which an original is mounted, a line sensor that performs photoelectric conversion on light from the original on the platen, a first carriage that moves along the platen and guides the light from the original to the line sensor, a first housing that stores and supports the first carriage to be movable along the platen, first driving means for moving the first carriage, a second carriage provided with a plurality of rod-shaped light-source lamps that applies light to the original, a second housing that stores and supports the second carriage to be movable along the platen and covers the platen, second driving means for moving the second carriage, and control means for controlling the first driving means, the second driving means and lighting of the plurality of light-source lamps.

Image reading apparatus

Film scanner

An image reader is provided with a transparent member which is placed in an optical path from the surface of an original document bed on the side of a carriage to a condensing lens, whereby when the transparent member exists at a predetermined position, the condensing lens can be focused on a translucent original existing at a position above the position of a reflection original. When the transparent member is at a second predetermined position, the condensing lens can be focused on the reflection original. The condensing lens can be focused on more than one position simply by placing the transparent member in the optical path, so that the structure is simple and the manufacturing costs can be reduced.

Image reader and image reading method

There are provided an image reading apparatus and a focus adjusting method thereof in which focusing can be accurately conducted by a simple moving mechanism. A condenser lens and line sensor can be moved being integrated with each other. When output values obtained when a document on AF line is read by a line sensor are represented by LS , LS , LS , . . . , and when a broken line graph is considered on which the horizontal axis represents a reading position in the horizontal scanning direction and the vertical axis represents an intensity of an output signal, it is judged that the larger the total distance LM &plus;LM &plus; . . . of the broken lines is, the more accurately the image is in focus. A square root of the sum of the square of a distance between the adjacent reading positions and the square of a difference of intensities of the signals which have been read, is calculated, and it is judged that the larger the sum is, the more accurately the focus is adjusted.
