摘要： A recording element unit includes a support member, a recording element provided on the support member and having a wiring layer for supplying electrical signals, and a bump-shaped electrode connected to the wiring layer so as to be raised therefrom. The bump-shaped electrode includes a plurality of raised portions. Such a bump-shaped electrode is also included in a recording element driving unit, an ink jet unit, and an ink jet driving unit. This arrangement solves the problem of the low reliability of the electrical connection between a recording element substrate, on which the electrode is positioned, and a driving element substrate, for driving the recording element. The unit also includes first and second protective layers with the second protective layer having a thickness greater than that of the first. This feature provides structural strength to the support member in order to prevent warping.

摘要： A color copier scans an original carrying a multi-color image in one direction to form toner images of different color components thereof on respective photosensitive drums while moving a transfer sheet in the opposite direction to transfer in registration thereon the several toner images and thereby form a composite color image of the original without reversing the rotational direction of the drums. After the latent image on a given drum is developed with a toner of a respective color, the drum is quenched to remove residual charge by irradiating it with light of a color which is not significantly absorbed by the toner on the drum. The quenching light color differs as between different drums, and for a given drum the quenching light color differs from the color of the light used to form the latent image on that drum.

摘要： An amplitude equalizer is provided for equalizing amplitude distorted signals within a predetermined frequency band. The amplitude equalizer comprises first means for splitting signals into first and second split signals. A first delay device receives one of the two split signals, and a second signal splitter splits the output of the first delay device into third and fourth split signals, the third split signal being applied to a second delay device having a delay equal to the delay of the first delay device. The output of the second delay device is combined with the second output from the first signal splitter in a first signal combiner, the output of which is applied to a circuit for adjusting the polarity and gain of the signal applied thereto. The output of the polarity and gain adjusting circuit is applied to a second signal combiner which combines the adjusted signal with the fourth output from the second signal splitter to thereby provide equalized signals. As organized above, the equalizer can provide for arbitrary selection of the desired frequency regions and maximium equalized amplitude by simply varying either the amplitude or attenuation factor, and by properly choosing the delay time. Further, equalization of secondary and higher order distortion can be achieved by virtue of constant delay over the entire frequency region.

摘要： In successively copying a plurality of continuous pages of a book original by means of a copying apparatus adapted to print images of the pages on opposite surfaces of each copy sheet, a printing operation is controlled in such a manner that a series of processes including, illumination of the pages, charging and exposing of a photosensitive drum, developing, fixing and transfer printing of visible images, and ejection of printed copy sheets is automatically performed, if the book original is opened at desired pages and placed on an original placing glass plate of the copying apparatus in a normal condition in which the top of the book original is remote from the operator. With the operator merely turning the pages, the control method enables the production of a bundle or bundles of duplicate copies of the pages of the same order and arrangement as the book original, regardless of whether the book original is bound on the left side or on the right side and whether the first and last pages to be copied have even numbers or odd numbers. In copying the adjacent two pages, two pages can be copied in separate copying processes or in a single continuous copying process for the two pages.

摘要： An enlarged electrostatic image of an original document such as a microfilm frame is formed on a photoconductive belt and is developed by means of a toner substance to produce a visible image. The belt is then moved to a viewing position where it serves as a screen for displaying the visible image. The belt is discharged and the toner substance removed therefrom after the display in preparation for displaying the image of another microfilm frame on the belt.

摘要： First and second rollers extend perpendicular to the direction of reciprocation of the scanning head and are disposed on opposite sides of the scanning head in said direction. First and second curtains are fixed at first ends to the first and second rollers respectively and at second ends to the scanning head. The curtains are rolled around the respective rollers. First and second pulleys are fixed for rotation with the first and second rollers. A tensioned wire is fixed at its opposite ends to the first and second pulleys and rolled around the first and second pulleys in directions opposite to directions in which the first and second curtains are rolled around the first and second rollers respectively. As the scanning head is moved thereby unrolling one of the curtains, the pulleys and wire rotate the other roller so as to roll the other curtain thereonto.
