Abstract: An image processing apparatus and control method are provided. An image processing apparatus including: a storage configured to store data which is divided into a plurality of units of code; a random access memory (RAM) configured to be loaded with the data; a central processing unit (CPU) configured to execute the data; and a storage controller configured to read a requested unit of code from the storage in response to receiving a request from the CPU for the unit of code to be currently executed, and load the read unit of code to the RAM so that the unit of code can be processed by the CPU, wherein the storage controller performs validation with regard to the unit of code when reading the unit of code from the storage, and loads the unit of code, when the validation passes, to the RAM.
Abstract: An image forming apparatus includes a scanning unit for reading image information, an image forming device for forming images corresponding to the image information, a memory for storing the image information read by the scanning unit, an identification device for identifying the users of the image forming apparatus, a setting device for setting the time period for maintaining the image information stored in the memory in accordance with the user of the image forming apparatus, and an erasing device for erasing the image information stored in the memory after the elapse of the time period set for each user by the setting device.
Abstract: A latent contact photographic copy of an original image is formed by apparatus comprising a translucent platen for supporting on one side thereof an assembly including an original image to be copied and an unexposed photographic film overlying the original image. Parallel connected lamps mounted on the opposite side of the platen are provided for irradiating the photographic film through the platen and original image. A cover is movable between an open position in which it uncovers the platen for receiving the assembly and a closed position in which it covers the platen and assembly. A circuit connected to the lamps includes a switch for selectively enabling the circuit to activate the lamps. The switch is mounted for contact with the cover when the cover is in the closed position. The switch is thus closed to effect exposure of the photographic film in response to pressure exerted on the cover when the cover is in the closed position.
Abstract: A contact printer for printing on photographic paper includes a generally pyramid-shaped lower housing having an exposure window with a transparent cover held by a generally rectangular peripheral frame for holding the transparent cover and a print mask over the exposure window with a light positioned at the apex of the lower housing and an upper housing encompassing the apex of the lower housing forming a chamber in which is disposed batteries and light control circuitry with an exposure activating switch and a light indicator positioned on top of the upper housing.
Abstract: A contact exposure unit having a transparent contact surface and a liquid development unit having means for preventing leakage of a developer are, respectively, constructed as independent units. The exposure unit and the development unit are adapted to be releasably combined with each other thereby to form a portable copier. Outer housings of the exposure and the development units constitute in combination the housing of the portable copier.

Abstract: An exposure system for a microfiche duplicating machine includes a mercury vapor light source and a light transparent platen disposed above the light source for supporting an original microfiche card and a duplicating film card for exposure by the light source. A shutter mechanism is interposed between the light source and the transparent platen to control the exposure of the duplicating film card, and a cover is disposed over the transparent platen to prevent the escape of light from the duplicating machine during the exposure. A mechanical linkage is provided for automatically opening a pair of shutters within the shutter mechanism upon the closing of the cover to initiate the exposure of the duplicating film card. Simultaneously, a timer is energized by the closing of the cover to initiate an exposure timing sequence.
