An image projector projects images according to inputted image data. A light source unit has at least a plurality of LED light sources configured as a single unit for emitting an illumination. A space modulation element is modulated according to inputted image data. An illumination optical unit leads the illumination light emitted from the light source unit, and illuminates the space modulation element. A projection optical unit projects an image illuminated by the illumination optical unit and modulated by the space modulation element. The light source unit is configured removably from the image projector.

In discharge recovery processing, a continuous sheetis moved from a facing position facing a head portionto a first position (in the down direction in the drawing) as an evacuating position in the discharge recovery processing, thereafter, a discharge recovery processing unitin the standby mode at a second position (in the up direction in the drawing) different from the facing position is moved to the facing position, and the discharge recovery processing is performed. In the discharge recovery processing, the head unitis not moved and therefore the preferable positional reproducibility is obtained after ending the discharge recovery processing.

Image forming apparatus

An illumination apparatus comprises a plurality of luminous bodies as light sources, luminous body drive portions configured to drive to light each of the plurality of luminous bodies, an optical member configured to lead and apply light exiting from a luminous body lighted by the luminous body drive portion to an illumination target area, a light control member configured to perform change of a light path of the light exiting from the luminous body with which the illumination target area is illuminated and/or movement of the luminous body, a movable portion configured to operably drive the light control member, and a light selection portion configured to control the movable portion and/or the luminous body drive portion in such a manner that light with which the illumination target area is selected from light exiting from the plurality of luminous bodies.

A projector comprises a light source, an optical system for illumination, a reflective light modulating device having a plurality of reflective elements arranged in matrix form to be illuminated by the light emitted from the optical system for illumination, and an optical system for projection. The optical system for projection includes a reflective surface configured to bend a projection chief ray reflected at the center of the reflective light modulating device among projection chief rays in the optical system for projection. The reflective surface has a predetermined angle to the ray which is emitted from the optical system for illumination and which strikes the center of the reflective light modulating device, and includes a P shaft parallel to one of an X axis and a Y axis along which the plurality of reflective elements is arranged.

A printer system includes a host computer, K, C, M, and Y printer elements for four colors, a paper feeding section, and a head cleaning section. The printer elements each include a head controller and print head groups. The head controllers are connected to the host computer via SCSI interfaces in a daisy chain. When printing, the host computer transfers information, such as an image-printing region, image-printing data, to the head controllers via the SCSI interfaces, thereby executing image printing. The printer system can control a large number of print heads with a simple configuration and also can perform high-accuracy image printing.

Printer system which uses a plurality of print heads and which controls the print heads with a simple configuration to achieve high accuracy image printing

An apparatus comprises first and second levers supported to be rotatable on a holder which holds a disc cartridge. The first lever has one end provided with a abutting pin which abuts the shutter to open the window of the cartridge, and other end connected to a shutter-closing spring to rotate the first lever to close the window and eject the cartridge from the holder. The second lever has one end coupled to the shutter-closing spring and other end provided with a push pin and connected to a break spring to make the push pin apply a force to the side of the cartridge. When the cartridge is inserted into the holder, the shutter-closing spring decreases the bias of the brake spring whereby decreasing the force with which the push pin pushes the side of the cartridge.
