Abstract:
An electrophotographic printer which includes a developing device for developing an electrostatic latent image formed on the surface of a photoconductor by adhering a developer thereto, a cleaning device for collecting the developer which remains on the photoconductor for reuse after the transference of the developer, and a toner recycling route for flowing the collected developer from the cleaning device back to the developing device by gravity. The photoconductor is exposed to a light source prior to the developer being applied to the surface of the photoconductor.
Abstract:
A non-magnetic one-component developer suitable for use in a contact or non-contact development system. The developer comprises 100 parts by weight of colored fine particles, which comprises a binder resin and a colorant, and 0.3-10 parts by weight of at least one fine inorganic powder selected from (i) a fine inorganic powder (I) obtained by subjecting a fine inorganic powder having an average particle size of 0.1-10 .mu.m and a heating loss (under drying conditions of 150.degree. C. and 1 hour) of at most 1 wt.% to a hydrophobicity-imparting treatment with a silicone oil and (ii) a fine inorganic powder (II) obtained by subjecting a fine inorganic powder having an average particle size of 0.1-10 .mu.m to a two-step hydrophobicity-imparting treatment with at least one compound selected from silane coupling agents and silazane compounds and then further with a silicone oil.
Abstract:
An automatic renting apparatus is for automatically renting rental articles and restoring returned rental articles. The automatic renting apparatus stores information concerning rental articles that have been rented out, rental articles to supplement or replace the stock, and the scheduled date of replacement or supplement. When the patron subscribes in advance for a rental article, information is displayed on a display unit to enable the patron to select a desired rental article for which the patron desires to make advance subscription. Upon the selection of the desired rental article and a desired renting date by the patron, information concerning the desired rental article and the desired renting date is stored in a subscription information storage unit.
Abstract:
An electrophotographic recording apparatus records an image on a recording paper, either a cut recording sheet or a continuous recording paper, through steps of feeding the recording paper along a paper feed plane exclusively for the recording paper, stopping the recording paper upon the arrival of the same at a predetermined, exclusive starting position, forming an electrostatic latent image on a photoconductor by an exposure unit as the photoconductor is rotated at a fixed surface speed, developing the electrostatic latent image in a toner image by a developing unit by applying a toner charged in a polarity opposite that of the electrostatic latent image, restarting the feed of the recording paper at a feed seed corresponding to the surface speed of the photoconductor upon the arrival of the first line of the toner image formed on the surface of the photoconductor at a position which will coincide with a fixed recording position on the recording paper at a transfer position, transferring the toner image from the photoconductor to the recording paper, and fixing the transferred toner image to the recording paper by a fixing unit. When the toner image is thus formed on the continuous recording paper, a portion of the continuous recording paper carrying the toner image is cut off by a cutting unit, and then the continuous recording paper is retracted to the starting position.
Abstract:
In an apparatus for processing embossed characters on an embossed card, a sensing head has sensing wires extending generally parallel with each other in a first direction, the tips of the sensing wires disposed at different positions along a second direction orthogonal to the first direction. The sensing wires are repeatedly actuated toward their tips. Advancement of each sensing wire exceeding a predetermined distance is detected and electrical signals indicating the results of detection are produced. The embossed card is moved relative to the sensing head in a third direction orthogonal to the first and second directions, with the surface of the embossed card held parallel with the second and third directions, and close to the tips of the sensing wires. The sensing wire is repeatedly actuated toward the embossed card so that the tip of each sensing wire hits or does not hit the surface of the embossed card before exceeding the predetermined distance depending on whether or not the sensing wire is confronting an embossment or not.
Abstract:
The present invention relates to a multihead serial printer comprising a plurality of printing heads mounted on different carriages and having a high-speed printing mode in which a plurality of printing heads print different letters and a high-density printing mode in which a plurality of printing heads print different parts of one letter. These two printing modes can be changed over between each other. A plurality of carriages are independently supported by a common guide and the carriages are respectively movable in the line direction by different driving sources. At least one carriage comprises a shift mechanism for moving the printing head in the row direction along the surface of a platen.
Abstract:
A device for the pressure fixing of a toner image contains a pair of pressure fixing rolls arranged in parallel to each other. An image record carrier is fed in between said pressure fixing rolls which, for the pressure fixing of the toner image, are pressed against each other through a pressure bar by means of a plurality of pressure generators. Said pressure generators are positioned displaceably in the axial direction of said pressure fixing rolls to adjust a load distribution depending upon the width of said record carrier.
Abstract:
A high speed printer utilizing a rotating type wheel having a plurality of spokes with at least two type characters, an outer type character and an inner type character.The spokes extend from the center of the wheel and each type character is preferably supported on the face of a corresponding spoke or radial extension. During the rotation of the type wheel, the wheel is moved in a plane parallel to the path of line printing. An outer character is formed at a predetermined angle to an inner character at one extreme end of a spoke. With each predetermined angular rotation of the wheel, the desired character may be printed in a columnar print position on the printing line.
