Abstract: In an image forming apparatus, plural LED light sources are provided for emitting lights of respectively different wavelengths, and, in reading an illuminated image with a reading sensor, a lighting mode setting register selects a first mode for reading the image with a single color or a second mode for reading the image with plural colors. The light emitting time of these light sources are set by a light emitting time control register, a light emitting time counter and an automatic light emitting time adjustment circuit, and the currents supplied to the light sources are set by a lighting current control circuit. A CPU controls these circuits according to the selected mode.

More specifically, the image processing apparatus has a print emulation command set for controlling the printer unit from the external information processing terminal, and a command set for controlling the data processing unit from the external information processing terminal. The print emulation command set is used when the printer unit is controlled, and the designated command set is used when the data processing unit is controlled.

Abstract: An inexpensive image communication apparatus allows an external information processing terminal to be connected thereto, and uses an interface capable of high-speed data transfer for communication with the PC. The image communication apparatus receives an instruction from the external information processing terminal through an interface control unit in a state in which reception can be performed. When an instruction from the information processing terminal is received while communication is preformed by a communication unit and an instruction from an operation panel is received, the image communication apparatus outputs information indicating that the instruction cannot be executed, in a state in which the interface control unit can perform transmission.

Abstract: There is disclosed an image processing apparatus which decodes code data to generate pixel data and prints an image on the basis of the pixel data by using a page printer, such as a laser beam printer, which prints an image on sheets of paper.

Abstract: An apparatus stores image data sent as a facsimile signal through a line in an image memory (103) and records the image data on a recording medium upon reducing the data. The apparatus further includes an interface for connection with an external information processing unit such as a personal computer so that image data input from the external information processing unit through the interface can be stored in the image memory (103) and recorded on a recording medium. Designation of image data in the image memory (103) is allowed from the external information processing unit. The designated image data is retained after a recording operation. In addition, a reducing/recording operation is inhibited when the designated image data is to be recorded.

Abstract: In a facsimile system received data is initially stored in an internal storage device, and subsequently is stored in an external storage device (hard disk drive or floppy disk drive) by a transfer process. The facsimile system stores the received data from a transmitting party in the internal storage device and determines a state of availability of the external storage device. When the external storage deice is available, the received data is transferred to the external storage device, and if not available, transfer is delayed until it becomes available.

Abstract: When image information is received, a main controller investigates the blank memory capacity of a floppy disk, after which the main controller executes processing for storing the received image information in an image-information semiconductor memory while confirming that sufficient blank memory remains in the image-information memory. If, during execution of the processing for storing the image information, the blank memory area of the image-information memory runs out so that no further image information can be stored there, or the quantity of image information to be stored in the image-information memory becomes greater than the blank memory capacity of the floppy disk, an error warning is issued, the processing for storing the image information is suspended and processing for interrupting communication is executed.

Abstract: A wafer cleaning method and apparatus in which a cleaning solution is caused to evaporate at a temperature below its boiling point, and cleaning vapor thus produced is applied at a temperature above its dew point to a wafer such as a semiconductor wafer. The wafer is cleaned without formation of colloidal silica in the absence of aerosol, or etched uniformly free of impurities. The wafer cleaning apparatus comprises a cleaning solution storage, a vapor generating section, a wafer supporting position of a wafer supporting device and a vapor supply section. These components are arranged in a housing to overlap one another in plan view and to lie vertically close to one another. The apparatus has a compact overall construction with simplified seals for preventing leakage of the cleaning vapor.

Abstract: An image communication apparatus stores received image data in a first memory, such as its hard disk drive, and transfers the image data stored in the first memory to a second, unloadable memory, such as a floppy disk, that may be unloaded to or unloaded from the apparatus. The load/unload status of the floppy disk is detected, indicating whether it is loaded to or unloaded from the apparatus, and the controller controls the transfer of the image data from the hard disk to the floppy disk in accordance with this detection. Specifically, the controller interrupts the transfer of the image data when the unload status is detected during transfer of image data, and resumes the interrupted transfer when the load status is detected after the interruption. An alarm may be sounded when the transfer of the image data is interrupted to indicate to an operator that a floppy disk should be loaded.
