An apparatus for printing images on a booklet comprises, first and second paired pinch rollers for conveying pages of the opened booklet to a printing head, located between these paired pinch rollers, a rotatable platen opposed to the printing head and located between the paired pinch rollers, guide plate for guiding one page of the opened booklet to the platen, and a press member for fixing the free end of the one page to the platen. The second paired rollers hold the other page of the booklet but may slipe the page when the free end of the one page is fixed onto the platen thereby adding tension to the other page of the booklet as the platen is rotated. The layout of the recorded images are changed and then printed on the page.

An image forming apparatus includes an image carrier, a means for forming colorant holding regions on the image carrier, the colorant holding regions having better ink or developing agent holding properties than the image carrier, a means for supplying a colorant to the colorant holding regions, and a means for transferring the colorant, held in the colorant holding regions, onto a printing medium.

A manual window regulator in which a pinion rotatably carried by a window glass and driven by a manual handle is held in engagement with a rack which is fixed to extend in the direction of movement of the window glass, so that a manual rotation of the handle causes the pinion to roll along the rack in meshing engagement therewith so as to drive the window glass thereby opening and closing a window. The transmission of rotation from the handle to the pinion is effected through a tape stretched between a drive gear rotationally driven by the handle and driven gear coaxially fixed to the pinion. The rack and the pinion are usable also as the parts of a power window regulator. The manual window regulator therefore can be easily converted into a power window regulator by using an electric motor for driving the pinion in place of the unit including the handle, the drive gear and the tape.

The present invention is aimed at reading picture image information of an original by illuminating the original with light and by receiving the transmitted or reflected light from the original. The picture image reader in accordance with the present invention includes an optical sensor for reading picture image information by receiving light from the original that is illuminated by light, a moving mechanism for relatively moving the optical sensor and the original, an overlapping mechanism for overlapping a portion of the reading region for picture images, in the reading of picture images by the optical sensor, and a synthetic picture image formation circuit for synthesizing picture image of the overlapped portion so as to have the picture image coincident with the picture image in the original, based on each picture image information that are read in overlapped manner. The overlapping mechanism comprises a control unit for controlling the moving mechanism so as to let the optical sensor read a portion of the region of picture images and/or a rod array lens arranged so as to have the images of a portion of the picture image of the original imaged in overlapped manner on the optical sensor that are composed of at least two of line image sensors. In addition, the synthetic picture image formation circuit comprises at least two of coefficient circuits for multiplying each of the picture image information of the overlapped portion with predetermined coefficients in order to weight the picture image information, and an adder for summing the weighted picture image information from each of the coefficient circuits.

An ink-jet recording apparatus records an image onto a recording medium by flying an ink-droplet from an ink surface by a pressure of an ultrasonic beam. The apparatus including an ultrasonic generating element array having a plurality of ultrasonic elements arranged in an array for emitting ultrasonic beams, a driving device for applying a plurality of pulses having different phases from each other, and a converging device for converging the ultrasonic beams by interfering the ultrasonic beams with each other. The generating elements are simultaneously driven and sequentially shifted in an array direction, and the converging device converging the ultrasonic beams in a direction perpendicular to the array direction.

A color multi-function type copying machine is disclosed which includes an image input unit for optically sensing an input image and generating an image signal. A function memory stores an ink color used in a color frame to be written in the input image in order to designate its partial image region and a specific image edit function assigned to the ink color and desired to be executed by an operator so that the ink color and the specific image edit function can be rewritten. When a closed loop-like color frame of a selected color is written in the input image, a color frame region detecting unit detects a shape and a color of the color frame. In response to the detection result, the memory is accessed to determine an image edit function corresponding to a first selected ink color of the detected color frame. A color edit unit executes one or a plurality of image signal processing corresponding to the determined image edit function for the input image signal. The edited image signal is supplied to a color printing unit via a signal processing unit and is reproduced therein.
