摘要:
A display for a copying apparatus includes a display element for indicating the operating conditions of the copying apparatus. The display has a number of detectors for detecting each of a group of operating conditions and an energizer for energizing the display element in response to the outputs from the detectors. The display element operates with a predetermined on-period and a predetermined off-period for each corresponding detector. The display is capable of displaying a group of operating conditions by a single display element through a group of display conditions such as being on, being off and blinking.

An electrostatic copying apparatus comprising a lower supporting frame, an upper supporting frame mounted on the lower supporting frame for pivotal movement between an open position and a closed position, a document placing means having a transparent plate for placing a document to be copied thereon, an optical unit and a driving source. Either the document placing means or at least a part of the optical unit is mounted reciprocally on the upper supporting frame and drivingly coupled to the driving source via a power transmission mechanism. The apparatus further includes an automatic locking means for automatically locking the document placing means or at least a part of the optical unit and cancelling the locking according to an operation of moving the upper supporting frame to an open or closed position or an operation incident to this moving operation.

An image forming apparatus includes an imaging assembly capable of forming an image on a copy sheet; a sheet inverting path disposed downstream of the image assembly and capable of transporting the copy sheet in a first direction; an intermediate tray unit arranged downstream of the sheet inverting path and capable of receiving the copy sheet transferred from the sheet inverting path and stacking a plurality of the copy sheets thereon; and a refeed unit capable of feeding copy sheets stacked on the intermediate tray unit in a second direction opposite to the first direction.
摘要:
A versatile electrostatic copying machine which can provide not only ordinary black-and-white and monochromatic copies and ordinary multi-colored copies but also artificial monochromatic and multi-colored copies of desired optional colors differing from colors of originals conveniently with ease without such troubles as color mingling and paper jamming is disclosed, said copying machine comprising an original-light exposing zone for irradiating an original to be copied in the stationary or moving state by a light source, a photosensitive layer-light exposing zone for light-exposing imagewise a statically charged photosensitive layer, an optical system for optically connecting said original-light exposing zone to the photosensitive layer-light exposing zone and projecting an image of the original on the photosensitive layer and a development mechanism for developing an electrostatic latent image formed on the photosensitive layer directly or after it has been transferred onto a transfer paper, wherein said optical system comprises a light-selecting mechansim for selecting an optional light from white light and color-separated lights and exposing the photosensitive layer to said selected light and an exposure light quantity-adjusting mechanism for adjusting the exposure light quantity to an optimum quantity with respect to each of a plurality of said lights, the development mechanism comprises a development operation-selecting mechanism for selecting an optional development operation among a plurality of development operations differing in the toner hue, and said light-selecting mechanism and development operation-selecting mechanism are actuated independently or in the state interlocked with each other so that a copy having a desired coloring effect can be obtained.
摘要:
Several embodiments of accelerating fuel systems and methods for delivering accelerating fuel to an internal combustion engine over an extended time period. In each embodiment, the accelerating pump delivers a portion of its discharge fuel to a storage chamber and the storage chamber redelivers the fuel to the engine after the completion of the pumping stroke of the accelerating pump. In some embodiments of the invention, the stored fuel is returned to the engine by gravity. In some embodiments, the stored fuel is delivered to the engine at a different rate than the rate at which it is stored. In some embodiments, the return rate is dependent upon the change of speed of the engine and in other embodiments, the return rate is responsive to the acceleration of the vehicle powered to the engine.
摘要:
An intake gas distributor extending from one carburetor to a pair of two-cycle internal combustion cylinders. The cylinders are horizontal and arranged one above the other. The distributor is bifurcated, and its branches are proportioned and arranged so that air/fuel mixture in substantially equal quantity and density flows to both cylinders, despite the inherent tendency of fuel to settle out of the mixture, especially at low load conditions.
