A mode control system is provided for a printer having an internal battery. The mode control system selects at least a charge operation for charging the battery and a printing operation for printing an image on a recording sheet fed into the printer. The mode control system also includes a manually operable member. A duration of an operation of the manually operable member is detected, and one of the charge operation and the print operation is selected in accordance with the duration of the operation of the manually operable member.

A thermal printer for forming an image on a sheet includes a thermal head having a plurality of linearly arranged thermal elements. A total number of thermal elements to be energized to form the line image is determined. A difference between the total thermal elements to be energized to form the line image, and previous number of the thermal elements that were energized to form a previous line image is calculated. The thermal elements are then driven for a period of time which is a function of the difference between the total number and the previous number that was calculated.

An apparatus for displaying a 3-D image has a projector, and a projection controller. The projector has a projection optical system, and projects a series of 2-D images on different projected-positions in a depth direction, in order, by using light passing through the projection optical system. Each 2-D image is formed on the basis of section-views of a 3-D object in the depth-direction. The projector repeatedly and successively projects the series of 2-D images so as to cause an afterimage-effect. In the present invention, the projection controller adjusts a projection-timing of the series of 2-D images, and controls the projection optical system in accordance with the projection-timing so as to focus each 2-D image and maintain a magnification of the series of 2-D images constant.

A micro-manipulator includes a gripping device having two gripping fingers for gripping a micro-material, and a gripping finger moving device for moving at least one of the gripping fingers of the gripping device. An exciting device vibrates the gripping fingers when the gripping fingers of the gripping device are opened to release the micro-material.

Disclosed is a focusing system for a scanner. The focusing system utilizes an imaging lens and a line image sensor of the scanner. The focusing system is further provided with a lens drive system, a contrast data detecting system that detects a contrast data representing brightness gradient with respect to a pixel located in a predetermined area on said line image sensor. Further, a lens position detecting system is provided. The lens position detecting system detects, among all lens positions, a position at which a brightness gradient of a certain pixel is greatest. Then, a controller controls the lens drive system to locate the lens to the detected lens position.

An ink transfer printer has an electrically-insulated base plate. An array of electric heater elements, aligned with each other, is provided on a surface of the base plate, the heater elements being selectively and electrically energized in accordance with a series of digital image-pixel signals. A frame member, having an opening, is securely provided on the base plate such that the array of elements is encompassed by the opening of the frame member. A sheet of film covers the frame member such that the opening of the frame member is defined as an ink space fillable with ink, and the film sheet has a plurality of fine pores arranged along the array, with at least one of the plurality of fine pores being allocated to each of the heater elements. A heat dissipating conductor is formed of a thermal conductive material, and is associated with the film sheet such that thermal energy, locally generated by an electrical energization of at least one of the electric heater elements, is promptly dissipated.

An image scanning device is provided that includes: an imaging lens; a linear image sensor; a rotating scanning system; and a shading correction system that corrects each pixel image signal for shading in accordance with image height and a magnification of the imaging lens. The magnification of the imaging lens changes according to the rotational position of the scanning system. The image scanning device may further include a color filter and a color correction system for correcting the pixel image signals for changes of wavelength transmittance of the color filter in accordance with image height and the magnification of the imaging lens.
