Abstract: An image processing apparatus which is equipped with card slots can cope with plural kinds of memory cards acting as media, and a recording apparatus does not occur a malfunction in its card reader due to a lack of a current to be supplied to the medium even when the plural media are respectively inserted in the card reader. To do so, when the media are initially inserted in the plural card slots, the slot in which the medium is first inserted is set to be available, and the remaining slots are set to be unavailable. Besides, power is not supplied to the slots which have been set to be unavailable.

Abstract: An image processing apparatus or a facsimile apparatus or the like is constructed by an input unit for inputting image data, a data conversion unit for converting density characteristics of image data inputted by the input unit, and an output unit such as ink jet printer, laser beam printer, or the like for outputting the image data at a predetermined resolution. The data conversion unit converts density characteristics so as to almost equalize densities even when a resolution of the image data that is outputted by the output unit differs. The data conversion unit converts the density characteristics of the input image data on the basis of a luminance/density conversion table formed every resolution of the image data that is outputted by the output unit. The resolution of the output image data is higher than the resolution of the input image data.

Abstract: A connector is provided with a first housing and a cover. The first housing has a terminal receiving chamber in which a first terminal is received, and is fitted to a second housing.

Therefore, the bus bar can be elastically deformed and flexed about the retaining member in a retracting direction of the terminal portion.

Abstract: An injector insulating cover includes a circumferential engagement portion in an inner wall portion. The circumferential engagement portion is engaged in a circumferential direction with respective apexes of a nut portion disposed in a head portion of an injector. When the insulating cover is attached so as to cover the head portion of the injector, the insulating cover cannot relatively rotate about the axis of the injector. Thus, the insulating cover can surely hold electric wires connected to terminals of the injector, so that electric wires elongate in a desired direction, and disadvantages such as that the electric wires come in contact with peripheral components and their insulating sheaths are damaged can be prevented from being produced.
