摘要： PURPOSE:To securely detect an operator by directly finding a distance from the device to an object to be detected, then deciding the presence or absence of the object, and providing the device with plural distance-detecting means. CONSTITUTION:The originating means 520, 620, and 720 of the device for detecting a business machine operator transmit a distance measuring medium towards the operator when he operates the business machine; and receiving means 530, 630, and 730 receive reflection from the reflecting object. Based on the characteristic that the medium is transmitted into air, measuring means 510, 610, and 710 measure a distance from the device to the reflecting object in the manner which is unaffected by the level of the reflection which the receiving means 530, 630, and 730 receive. The measuring means 510, 610, and 710 independently measure it; when one measured result out of plural obtained measured values is within the prescribed range, the information processing means 400 judges that the operator exists. Thus, the operator can be accurately detected.

摘要： PURPOSE:To record additional information at an optional position and to suppress an increase in size by projecting a light image on a photosensitive body by exposing and scanning a document, and thus recording an image different from an analog image in a specific area additionally. CONSTITUTION:A CPU 90 sends area data for erasing unnecessary charges on a photosensitive body at the peripheral part of transfer paper according to data on the size of set transfer paper and data in an area set as an overlay area to a controller 10, and starts a recording process to form an electrostatic latent image of the document placed on an original platen. Then, process of development, transfer, separation, and fixation are carried out in order and a transfer paper conveyance path is controlled to guide a fixed recording image to a paper refeeding tray in a state where an image can be formed on the same surface. The CPU 90 sends the area data, overlay data, and its top-bottom data to a write controller 101 so that blank data is written in an area other than the overlay area and specified overlay data is written in the specified overlay area. Consequently, the additional information can be recorded at an optional position and the device never increases in size.

摘要： PURPOSE:To prevent a color shift by driving directly plural photosensitive drums by step-motors being independent and having an equal step angle, respectively, and allowing the switching timing of a driving pulse of the step-motors to coincide. CONSTITUTION:From a pulse generator OSC for determining the rotational speed of each step-motor 16 (16B, 16y, 16m and 16C), a common signal is inputted to driving pulse generators 17 (17B, 17y, 17m and 17C), and each generator 17 generates a driving pulse so as to be given to the winding of each phase of each motor 16, based on an inputted pulse. The driving pulse of each phase is inputted to power drivers (18B, 18y, 17m and 18C), a current is allowed to flow to the winding of the motor 16. In such case, each motor 16 rotates and allows the current to flow to the winding of drums 1 (1B, 1y, 1m and 1C). As a result, each motor 16 is rotated, and allows to rotate the drums 1. In such way, the color shift can be prevented.

摘要： PURPOSE:To make an invariably optimum density adjustment corresponding to editing functions by detecting the density of an original image in a necessary area. CONSTITUTION:A phototransistor PH1 is applied with a specific voltage Vcc from a photosense amplifier 1 through a screened cable and generates a collector current corresponding to the intensity of photodetected light, so the intensity of the original reflected light is detected as the voltage across a resistance R1. An operational amplifier OP and a resistance R2 constitute an amplifying circuit with high input impedance to amplify the voltage across the R1. Its output has its high frequency component removed by a resistance R3 and a capacitor C1 and is outputted to an A/D converter. The A/D converter inputs the outputs of sensors 1-3 at the same time and selects one of them according to a selection signal from a CPU to output digitally-converted original density data.

摘要： PURPOSE:To prevent an erroneans operation of an operator from giving an influence to a device and to enhance an operability by synthesizing and storing an erasing area by a setting erasing area and erasing area except an original setting means and erasing an sensitive electric charge of the area. CONSTITUTION:An image forming light is received by a sensor 37 at a position conjugating with a sensitive drum 9 on which an original image by an exposure lamp 3 is formed and an area except the original is detected and a CPU sets an erasing area except the original. In accordance with an designated coordinates through a keyboard, the CPU calculates a setting erasing area synthesizes it with a setting erasing area except the original and stores the synthesized erasing area in an incorporated RAM. Based on this memory content, through an eraser 24, an electric charge of the sensitive body 9 is erased. In these manners, an area having no meaning in a copy is not automatically developed but the erroneans operation of an operator is prevented from giving an influence to a copying machine having an editing function. An erasing area information is stored and during using the same data, a key operation is not needed and an operability can be enhanced.

摘要： PURPOSE:To prevent the erroneous operation of an operator by detecting the condition of a partial deletion mode completion and returning automatically to a standard mode by doing this. CONSTITUTION:IC1-IC19 successively shift an S-IN signal, a latch signal is inputted by the number M of a clock, and then, the signal is latched as parallel data, transferred to a LED driver, and a LED78 is energized/non-energized for control. Thus, a CPU80, in a timing T3, energizes and controls the LED78 between 0-S1, P1-P2 and S2-M of an eraser 24. When a designated area is erased at a timing T2, the area is returned to a usual side erasing. At such a case, for example, a count register of the counter 0 of a P timer 94 is set to M, the count register of a counter 1 of the P timer 94 is set to 1, and the H output which continues until the count register is latched to an out 1 of the counter 1 of a P timer 94, appear.
