A lens apparatus includes an optical system having an aperture unit and a plurality of extender lenses that are selectively locatable in an optical axis. The lens apparatus is mountable on a camera having an image pickup element. To maintain the brightness of the image when changing the extender lens, the lens apparatus has a memory in which correction data associated with aperture values for each extender lens, and the aperture unit is driven using the correction data according to information on the extender lens.

The present invention provides a driving method using a liquid crystal light modulating device including transparent electrodes which each have a horizontally alignment film; and a liquid crystal composition which contains at least a chiral dopant, a dichroic dye and a host liquid crystal. The transparent electrodes face each other to have a cell gap having a width of 10 μm or less therebetween. The liquid crystal composition is filled into the cell gap, and has a positive dielectric constant anisotropy. The driving method attains display-switching by (a) applying a higher voltage than a threshold voltage of the liquid crystal composition into the device so as to be transparent and colorless, (b) applying a lower voltage than a threshold voltage so as to be light-scattered white, or (c) applying no voltage so as to be colored.

An electronic keyboard instrument in which the efficiency of sound emission is enhanced by preventing a soundboard portion having a large vibration amplitude from being hidden by a musical score plate to make sound emission of the soundboard to be hardly hindered by the musical score plate. A musical stand device is disposed rearward of a key-depression part of a keyboard and right above the soundboard, and has a musical score plate disposed close to and parallel to an upper surface of the soundboard when the musical score plate is in a fallen state. The soundboard is excited for sound production by transducers disposed on a lower surface of the soundboard. The transducers are disposed at positions where the transducers do not overlap, as viewed in plan, the musical score plate which is in the fallen state.

At least one exemplary embodiment is directed to a projection optical system that projects an image of a pattern of a first object onto a second object includes a first image forming optical system, a second image forming optical system, and a light-shielding member. The first image forming optical system forms an intermediate image of the pattern, and includes a concave mirror and a reflecting mirror. The concave mirror has a reflecting surface opposing the second object. The reflecting mirror directs light from the first object to the concave mirror. The second image forming optical system forms an image of the intermediate image onto the second object, and includes a lens. The light-shielding member is disposed between the concave mirror and the lens.

It is an object of the present invention, when using image scanner(s) to capture image(s) of original(s) and using printer(s) to print same, to enable four-sided borderless copying such that margin(s) do not appear on printout(s). An image scanner might capture an image corresponding to scan region 263 which might be somewhat larger than original 262. Image processing circuitry might then enlarge an image corresponding to scan region 266 (arrow 279), converting it into enlarged image 271. Within enlarged image 271, the image of original 262 might have been enlarged so as to become image 273, which might be somewhat larger than printing paper 274. This enlarged original image 273 which would be present within enlarged image 271 might then be printed by a printer.
