Abstract: A data eraser for erasing data recorded on a data recording medium, where data recorded on the recording medium can be erased in a short time period. Data produced in the CPU of the controller is stored in the memory as a random unit data; the unit data are repeatedly and continuously written in the memory to constitute record data for erasing purpose; the thus produced recording data for erasing are written on the hard disc to erase the data memorized in the hard disc. Since the time for producing random data, which normally takes time, is shortened, the time for proceeding as a whole can be shortened.

Abstract: An image data control apparatus includes a memory for storing image data and a reader for reading the image data from the memory. The reader can operate in a first mode for erasing the image data in association with the reading of the image data from the memory and can operate in a second mode for restoring the read image data in the storage means in association with the reading of the image data from the memory.

Abstract: A server which smoothly transmits/receives a moving image from image sensing device via the Internet. The server comprises a camera which converts an object image into an image signal, a camera controller which controls the camera, and a camera driver. When the image signal converted by the camera is transferred as still-image data on the Internet, the data is transferred by the HTML or HTTP protocol, on the other hand, when the image signal is transferred as moving-image data, the data is transferred by another protocol.

Abstract: An image-sensing server performs moving-image transfer service by sequentially transferring live video images obtained by a video camera via a general network such as the Internet. When live video images are requested from an external device as a client on the network, a system controller controls data-transfer amount per unit time of an image obtained by image sensing by the video camera, in accordance with traffic status on the network, and transfers the image data to the external device.

Abstract: A battery tray made of a composite FRP member having a structure such that reinforcing fibers are disposed on the two vertical ends of a balsa member and composite-molded with resin by press molding, and having a bottom floor portion, wall portions and a pair of flange portions, wherein the balsa member is disposed in the bottom floor portion.

Abstract: There is provided an information processing apparatus having a detachable first ROM cartridge in which a control program and other information are stored; an instructing device to instruct whether the control program stored in the ROM cartridge is to be executed or not when the ROM cartridge is attached; a control circuit to control operation in response to an instruction of the instructing device; a second ROM cartridge which is provided in the apparatus and in which a control program is stored; and a detector to detect whether the first ROM cartridge is attached or not. When the instructing device instructs not to execute the control program stored in the first ROM cartridge, the control circuit allows the control program stored in the second ROM cartridge to be executed. With this apparatus, when the detachable ROM cartridge is attached, the information other than the control program can be read out of this ROM cartridge and can be used for various processes.

Abstract: A recording apparatus such as a laser beam printer has a laser beam unit for forming an image, a cassette for automatically feeding paper sheets, a manual insertion port for allowing manual insertion of paper sheets, a switch to allow selection of the cassette sheet feed or manual insertion sheet feed at the side of the printer, a timer to count a predetermined period of time, and a CPU for switching from the manual insertion sheet feed mode to the cassette sheet feed mode when no paper sheet is manually inserted in the manual insertion sheet feed mode after the time in the timer has elapsed. Undesired accumulation of data designating printing in the cassette sheet feed mode is prevented.

Abstract: An output apparatus includes a storage device for storing font information; a unit for generating a predetermined pattern in accordance with the font information stored in the storage device; a unit for instructing to output a font list of the font information; and an output unit responsive to an instruction from the instructing unit for outputting a font list having a desired resolution.

Abstract: A printing system which controls whether to print on a manually-inserted sheet or a sheet fed from within a sheet cassette. Data received from a data source includes both print data and instruction data which indicates whether to print on a manually-inserted sheet or a sheet from within the sheet cassette. The received data is discriminated to determine whether it is instruction data or print data, and the instruction data is discriminated to determine whether it indicates to print on a manually-inserted sheet or a sheet from within the sheet cassette. The printer is thereafter controlled so as to print an image corresponding to the print data on a sheet fed in accordance with the discrimination of the instruction data.

Abstract: A control apparatus and method, in which a format for a particular instance of recording is designated or set, as by instructions from a host computer, or from an operator via a keyboard, and that desired format is used or not, according to whether the necessary information for that format is present in a memory (preferably non-volatile). If the necessary format information is present in the memory, the desired format is used for recording, while otherwise, a default format is used instead or the information for the desired format is supplied to the memory.

Abstract: In the disclosed recording apparatus, the printing condition of a format, for example of a business form, can be suitably modified by an instruction from a host computer. The modified format is then stored in a non-volatile memory, so that it need not be readjusted repeatedly for repeated printing operation.

Abstract: A multi-color image forming apparatus includes a first memory for storing a plurality of image data together with corresponding color data. An output device is provided for outputting image data onto an output medium. A designation device is provided for designating desired ones of the plurality of image data stored in the first memory and positions on the output medium at which the designated image data are to be output. A plurality of second memories are provided, each storing designated image data for a different color. Control circuitry controls the output device and the plurality of second memories to output the designated image data at their respective positions and in their separate colors on the output medium.

Abstract: An image output apparatus for the composite printing of images in at least two colors includes an internal memory for storing plural items of form information along with output-color information peculiar to each item of form information. When character symbol information inputted from an external unit is printed out after one item of form information is selected, a form pattern expressed by the selected form information is printed out in an output color of its own.

Abstract: There is a recording apparatus such as a laser beam printer comprising: a host computer as an external unit for inputting data to be recorded and control command to process the recording data; a recorder to record onto a recording medium in accordance with the input data; an error detector to detect errors in the input control commands; a data generator to generate an error code indicative of the occurrence of the error when the error is detected by the error detector; and a controller to control the recorder so as to record the error code onto the recording medium together with the input data. The error code is recorded as an error pattern of a visible image to the end portion of the recording medium such as a cut sheet paper. With the apparatus, the operator can easily know of the occurrence of the error in the input data and the kind and position of the error without interrupting the recording operation. The recording efficiency is improved.
