Abstract: A color image reading apparatus having a color sensor with plural sensor groups, the color sensor for separating an objective image into plural color components and for converting the plural color components into plural color component signals, and a shading corrector for performing shading correction for the plural color component signals. The shading corrector causes the plural sensor groups to substantially simultaneously read a reference plate and automatically corrects a shading correction state for each of the plural color component signals in accordance with data obtained from the plural sensor groups.

Abstract: A halftone image recording apparatus includes means for recording an image on a recording medium, inputting an image signal representative of an image which includes a plurality of density levels, generating a plurality of pulsed periodic signals having different widths of one period of the image signal, selecting at least one periodic signal with a preselected pulse width among a plurality of the periodic signals, combining the selected periodic signal with the image signal, and applying the combined signal to the recording means.

Abstract: An image processing apparatus receives color data and includes a masking processing circuit for modifying the colors represented by the color data by processing each of the different color data received. The colors are modified according to other color data associated with each of the colors represented by the color data. The masking processing circuit includes a first memory for storing data representing each color and a second memory for storing data from the data derived after masking processing the data stored in the first memory. The color data and the other color data are used as addresses in the first and second memory. The number of bits of each color data used as an address for each respective color is larger than the number of bits for each of the other color data received at that portion of the memory.

Abstract: An apparatus and method for stabilizing an output of a D.C. power source by using a micro-computer to regulate an input voltage to provide an output voltage according to a controlling signal. The invention further utilizes a periodic interruption process in the program sequence which moniters the output voltage, compares it to a predetermined level and regulates the output voltage in accordance with the monitered voltage.

Abstract: A method of manufacturing a fan guard from a plate member wherein inward slits, each having at least a radial slit section are formed in a first section of the plate member located between a central section and a ring-like section radially outwardly spaced therefrom of the plate member such that the radial slit sections extend from the central section to the ring-like section in circumferentially spaced relation to each other. Radially outward slits, each having at least an arcuate slit section, are formed in a second section of the plate member located between the ring-like section and an outer peripheral section of the plate member such that the arcuate slit sections extend from the ring-like section to the outer peripheral section in circumferentially spaced relation to other. Portions each extending between the adjacent two radial slit sections are bent to form louvers.

Abstract: An air conditioner including a room temperature detector, a room temperature adjuster and a controller is disclosed which is provided with a photodetector, and in which the temperature set in the room temperature adjuster is changed on the basis of the illuminance detected by the photodetector, and a signal for controlling a compressor is generated by the controller in accordance with the temperature thus changed.

Abstract: In an electrophotographic copying machine of the type using a slit exposure optical system with reciprocating carriages, movement of these carriages at the time a transfer medium is being processed in the usual fixing device often causes a jittering of the apparatus which adversely affects the quality of the image being fixed. The method according to the present invention avoids this problem by assuring that there is no movement, particularly no return movement of the carriages from the time the transfer medium enters the fixing device until it is discharged therefrom.

Abstract: During original document scanning, the forward clutch effects scanning travel of the optics unit in a copying machine having user selectable modes for magnification copying and is normally disengaged by detection of the trailing edge of a transfer sheet being transported through the machine; the return clutch for reverse optics unit travel is simultaneously actuated by detection of the sheet's trailing edge to return the optics unit to its original position. In the event that the trailing edge is not detected before expiration of a predetermined time period corresponding to maximum permissable forward travel of the optics unit for the selected magnification mode, the forward clutch is immediately disengaged, although the return clutch is not engaged until the sheet's trailing edge is subsequently detected.

Abstract: In an optical scanning system for a copying apparatus, it is known to reciprocate the equipment so that an image to be scanned is applied, for example, to a photosensitive drum, developed, and eventually applied to a recording medium. It is essential for each scanning cycle that the scanning function restart at the proper starting position. This objective is attained by the present invention which first moves the scanning equipment back to a position spaced from the initial starting position and only then completes the movement to the initial starting position. Strains on the equipment involved in an immediate forcible return to the initial starting position are thereby avoided.

Abstract: An apparatus for detecting a residual quantity of toner remaining in the supply hopper of a copying machine includes a piezoelectric vibrating element disposed in a wall of the hopper and having a surface normally positioned in contact with toner in the hopper, and an electronic circuit for causing vibration of the element at a predetermined frequency and for detecting changes in operating characteristics of the element as representative of a decrease in the amount of toner in the hopper to operate a warning device.

Abstract: Apparatus for separating sheets from a belt driven photosensitive surface in which a pair of rollers are disposed on opposite sides of the photosensitive surface downstream of the transfer paper feed point. One of the rollers is movable from a position spaced from the photosensitive surface to a position in which it contacts the sheet carried by the photosensitive surface and cooperates with the other roller to separate the sheet from the photosensitive surface. A sensor is provided to detect the absence of a sheet and to prevent the movable roller from contacting the photosensitive surface in the absence of a transfer sheet.
