Abstract: An image reading apparatus is provided with an optical reading device for scanning a stationary original placed on a platen to read image on the original; a drive device for moving the optical reading device at the first moving speed and the second or slow moving speed; a detection device for determining a type of image data read by the optical reading device as either the first type, i.e. monotone data, or the second type, i.e. color data; and a scan control device for obtaining and storing image data while scanning a document at the first moving speed. A switching control device switches the drive device to the second moving speed when the detecting device determines the image data read at the first moving speed to be the second type.

Abstract: A controller moves a scanner at least to the farthest end portion of an original document placed on a platen in a forward moving action, and the original document is scanned in a reverse moving action of the scanner. In the case when an original document is fed by an original document feed device onto the platen, the scanner is started for a forward movement before the original document feeding operation is completed.

Abstract: An image reading device reads a document using a plurality of reading modes including a sheet-through reading mode for reading a document at a fixed reading position while the document is automatically fed. The image reading device includes a first resolution changing means, a second resolution changing means, and a resolution setting means. The first changing means changes one of a linear velocity at which the document is fed and a traveling speed of a reading carriage to change a resolution at which the document is read in a sub-scanning direction. The second changing means electrically interpolates image data output from the first changing means to change a resolution of the image data. The resolution setting means provides a plurality of combinations of resolution change rates between the first and second changing means as resolution change modes and sets the first and second changing means to one of the combinations.

Abstract: A light beam (L) modulated with image information has its optical axis moved in a given direction by a light beam moving unit (38), and reflected successively by a plurality of rotating reflecting mirrors (58, 60) of a spinner (40) to a photosensitive medium (S). The movement of the light beam (L) which is caused by the light beam moving unit (38) is controlled depending on the speed at which the reflecting mirrors (58, 60) move and the direction in which the reflecting mirrors (58, 60) move, so that the light beam (L) reflected by each of the reflecting mirrors (58, 60) can scan the photosensitive medium (S). An image represented by the image information can efficiently be recorded on the photosensitive medium (S).

Abstract: A laser beam (L) emitted from a laser beam generator (18) is modulated by a laser beam modulator (40) depending on an image to be recorded, and then converted into a linearly polarized light beam having a predetermined direction of polarization by a polarization switcher (42). The linearly polarized light beam is then converted into a circularly polarized light beam by a quarter-wave plate (44). The circularly polarized light beam is converted by a quarter-wave plate (20) of a rotatable unit (28) into a linearly polarized light beam, which is applied to a polarization beam splitter (22). If the linearly polarized light beam is an s-polarized light beam, then the laser beam (L) is reflected by the polarization beam splitter (22) toward a recording medium (F). If the linearly polarized light beam is a p-polarized light beam, then the laser beam (L) passes through the polarization beam splitter (22). The laser beam (L) passes through a quarter-wave plate (24) and is reflected by a convex mirror (26) and then by the polarization beam splitter (22) toward the recording medium (F). The laser beam (L) is thus applied substantially in its entirety to the recording medium (F) for thereby recording a two-dimensional image efficiently on the recording medium (F).
