A document reading apparatus comprising a document table, a reading section disposed above the document table for reading a document placed on the document table. The reading section includes a sensor for detecting variations of brightness within a selected reading area of the document which is designated by light beams prior to a reading operation. This apparatus further comprises a display device for displaying the image of the selected reading area.

A device for adjusting the amount of exposure for use in copying machines or in the original reading device of facsimile systems comprises an illumination system having a first illumination optical path and a second illumination optical path through which the light from a light source is concentrated on the surface of an original for illumination. The amounts of light through both the first and second optical paths are controllable to provide an adjusted uniform amount of exposure without impairing the balance between the two paths in the amount of light. A single light blocking member disposed at the intersection of the first and second optical paths and movable into the paths regulates the amounts of light through the two paths. The device is therefore simple in construction and inexpensive.

An actuator included in a head substrate of an ink-jet head receives, with an electrode on the surface of the actuator, power fed from the wiring of a wiring substrate arranged opposite the head substrate. A first electrode of the wiring substrate is electrically connected to the wiring, and protrudes to the side of the head substrate. A second electrode is electrically connected to the electrode on the surface of the actuator, protrudes to the side of the wiring substrate and is electrically connected to the first electrode. The head substrate and the wiring substrate are adhered to each other through an adhesive layer such that a space to which the first electrode and the second electrode are exposed is hermetically sealed. The hermetically sealed space is in a vacuum state or is filled with a gas containing a predetermined amount of water or less.

A medical bag formed of a flexible material includes a front bag part and a rear bag part joined together to form a bag body. A closable liquid inlet port is provided in an upper part of the bag body. The medical bag further includes a deformable elongated member provided in the vicinity of the liquid inlet port on at least one of the front and rear bag parts. The elongated member is deformable so as to retain the liquid inlet port in an open configuration when the elongated member is in a deformed state.

A first frame has a U-shaped cross section and includes first and second bent portions, and an X-axis actuator is mounted at a specified position of the outer surface of the first bent portion. A second frame has a U-shaped cross section and includes first and second bent portions, and a Y-axis actuator is mounted at a specified position of the outer surface of the first bent portion. A Z-axis actuator is mounted at a suitable position of one end surface of an image pickup unit with respect to X-axis direction. The second frame is disposed between the first and second bent portions of the first frame, and the image pickup unit is disposed between the first and second bent portions of the second frame. The image pickup unit is made movable along three axial directions by the respective actuators. There can be provided a dust removing device and a photographing apparatus with which a clear image having no or little influence of dust can be obtained even if the dust is attached to an image pickup unit and the like.

摘要:
The present invention is an actuator using a piezoelectric element as a displacement element, wherein a drive signal voltage and current are reduced, and power consumption is reduced, while output is increased. A structure comprising two displacement units of laminate-type piezoelectric elements 10 and 10′ and elastic elements 25 and 25′ resonated by the piezoelectric elements are arranged so as to mutually intersect, and a tip 20 provided at the intersection point of the elastic members 25 and 25′ describes a circular path or elliptical path, and moves a rotor 40. The oscillation of the piezoelectric elements 10 and 10′ is suppressed by the elastic members 25 and 25′, so as to set the phase of the electromotive force produced by the voltage effect of the piezoelectric elements 10 and 10′ themselves to the opposite of the phase of the drive signal, thereby reducing current consumption. Making the spring constant of the elastic members 25 and 25′ smaller than the spring constant of the piezoelectric elements 10 and 10′ expands the displacement of the elastic members 25 and 25′ greater than the displacement of the piezoelectric elements 10 and 10′.

A driving apparatus that improves the precision of driving control for a driven member by reliably ensuring the desired motion of the tip member. Regulating members, which hold a piezoelectric actuator at positions opposite a rotor R, are located at positions separated from the piezoelectric actuator by a distance L that equals or exceeds the amplitude of the oscillation generated in the piezoelectric actuator.

High resolution composite images and ultra wide composite images are produced in a digital camera which combines a plurality of images to form a composite image on a single sheet. An image sensing unit includes a movable image sensing optical unit having a first and second focal lengths and a two-dimensional image sensing device. The image sensing unit is driven to control the optical axis of the image sensing optical unit so as to capture a plurality of images via the two-dimensional image sensing device. The plurality of images are combined to produce a composite image. An ultra wide composite image at standard resolution is produced by setting the focal length of the image sensing optical unit at a first focal length on the wide angle side, and a high resolution composite image is produced by setting the focal length of the image sensing optical unit at a second focal length on the telephoto side.
