摘要： A light modulation type photointerrupter includes: a light source that emits a light pulse to a transit area where an object transits; a driving circuit that drives the light source to emit the light pulse; a photoreceptor that converts the light pulse from the transit area into a pulse current and outputs the pulse current; an integrating circuit that integrates a pulse signal resulting from the pulse current and outputs a result of the integration, the integrating circuit having different time constants at a rise and at a fall of the pulse signal; and a detecting circuit that detects, based upon the output from the integrating circuit, presence or absence of the object in the transit area. The light source is driven to emit a pulse, which reduces the loss of power in the light emitter and the consumption of the current.

摘要： Originals are fed onto a platen glass one by one by an automatic original feeder to be read out by a reading system. The originals are converted into digital image data. The image data is transferred to a memory unit. The memory unit is controlled by a CPU. The memory unit is configured of an image memory, a sentence direction recognizing portion, an RAM producing a management table, an original direction (top and bottom direction) recognizing portion, a rotation processing portion, a sign memory and the like. Based on top and bottom directions of original images and directions in which sentences run included in the images, arrangement of images in a 2in1 or 4in1 mode is determined.

摘要： In an image forming apparatus for reading a document image and forming the document image on a paper, document image data are divided into a plurality of blocks and the document image data are compressed in the unit of block to be stored in a first memory device. The data read from the first memory device are expanded in the unit of block to be stored in a second memory device. Compression time and expansion time are estimated and image output start time for a printer is set based on the compression and expansion times before expansion of all the blocks is completed. In a different way, the start time is set to read data from a second memory device by a printer for printing, after estimation based on expansion time on data not yet expanded by an expansion device. In a still different way, predetermined form data such as page number are superposed with image data. The form data is drawn first in a page memory device and expanded image data are superposed next in the page memory device. Print is started by taking drawing time of the form data into account.

摘要： A digital copying machine as an example of an image forming apparatus sets a copying operation time period per sheet based on the size of a copying sheet. If the remaining number of sheets corresponding to an expendable in the digital copying machine decreases, time at which this expandable runs out is displayed, and time at which a discharge tray is filled is displayed if the number of sheets to be discharged onto the discharge tray is expected to exceed a fixed value. As a result, an image forming apparatus permitting an operator to smoothly perform processings with the apparatus if a copying operation to a set of documents formed of a plurality of sheets cannot be completed.

摘要： A dc-stabilized power circuit which has a PNP-type output transistor that is connected between input and output terminals, a base-driving circuit for controlling the driving current of the base of the output transistor in response to the difference between a voltage obtained by voltage-dividing the output voltage from the output terminal and a reference voltage that has been preliminarily determined, and a driving-current suppressing circuit for detecting a voltage between the input and output terminals and for suppressing a driving current released by the driving-current supplying means based upon the result of the detection. The greater the input-output voltage, the further the driving-current suppressing circuit suppresses the driving current from the base-driving circuit to the output transistor, thereby suppressing the output current. Thus, in a dc-stabilized power circuit of a low-loss type which has no current-detecting resistor connected in the output line and which is provided with a control circuit that is constructed as an integrated circuit and that supplies a driving current to the base of the output transistor in response to the output voltage, the power loss due to the output transistor is suppressed to not more than a predetermined level; therefore, it is possible to prevent damage to the output transistor beforehand.
