Title: Method and device for identifying recording medium
Inventor: TAKAHASHI HIROHITO
IPC: G11B19/12
Filed: 1997-07-08
Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for identifying recording mediums which allow the installment of many sensors that generate no faulty contact even when the varieties of recording mediums increase. SOLUTION: This method allows to identify the variety of a recording medium 31 from a mark section 33 formed on the cartridge 30 of the recording medium 31. This time, identifying marks are formed as segments of reflector 34 and those of non-reflector 35 on the external surface of the cartridge 30. Under the condition that the cartridge 30 is loaded in a removal disk device 10, reflection type photo interrupters (22a,...22d) which receive and reflect the light installed on the positions that oppose all the marks formed on the cartridge 30 are used to detect the arrangement of the marks of reflectors 34 and non- reflectors 35 of the loaded cartridges to identify the varieties of the recording mediums 31.

Title: Image forming device
Inventor: TODA KUNIO
IPC: G03G15/08
Filed: 1988-07-20
Abstract: PURPOSE:To obtain an image of high quality without unevenness in density or fogging by eliminating the density gradient in the direction of a developing sleeve axis generated in a carrying path of each developing device by making the carrying direction of developer in the carrying paths adjacent to developing sleeves counter each other in a first developing device and a second developing device. CONSTITUTION:In the first developing device 1, the developer in the carrying path 7 is carried from the backside to the fore side in the direction of an arrow P1 by a packet roller 13, and in the fore side edge part it is fed through a passage 9b in the direction of an arrow P2 to the carrying path 8. Then the developer in the carrying path 8 is fed from the fore side to the back in the direction of an arrow P3 by a screw 17, and in the edge part in the back side fed from the passage 9a to the carrying path 7 in the direction of an arrow P4. On the other hand, in the second developing device 2, the developing material in a carrying path 37 is carried to the backside Q1 by the packet roller, fed to the carrying path 38 from an arrow Q2 through a passage 39a. The developer in the carrying path 38 is carried to the direction of an arrow Q3 to the fore side by a screw 47, and fed to the carrying path 37 in the direction of an arrow Q4 through a passage 39b in the edge part in the fore side. Thus the developer is carried in counter directions in the developing device 1 and 2.

Title: Guide line for unmanned carrier
Inventor: MIURA TOKUNORI
IPC: G06F19/00
Filed: 1985-08-19
Abstract: PURPOSE:To cope with the change of the drive route of an unmanned carried without changing the position of a sign body, by forming the boundary lines continuous between adjacent sign bodies and non-sign bodies into a lattice and setting a guide line on the road surface along the boundary line. CONSTITUTION:The magnetic sign bodies 1 and floor tiles 2 are set alternately in a lattice form on a plane. While the detecting elements 4a and 4b of a magnetic sensor 4 set on an unmanned carrier 3 are set so that they are fixed at the symmetrical positions centering on a guide line (boundary line) when the position shift of the carrier 3 is equal to zero. The sum (Va+Vb) of the outputs of both elements 4a and 4b has such output characteristics as shown in the diagram against the shift of the carrier 3 from the guide line. Thus the carrier 3 detects the direction and amount of its position shift from the output signals of the elements 4a and 4b and at the same time performs the steering for its automatic drive. The relation of values between both outputs Va and Vb is reversed in case the sensor 4 covers both areas A and B. Therefore it is possible to detect the shift of an area, i.e., the pass through an intersecting point on the guide line from the difference between both values Va and Vb. In addition, the sloping degrees are different between both areas A and B for the sensor output (Va+Vb) against the position shift. Even in such a case, it is possible to detected and correct the present area.

Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To enable even a user to easily exchange a belt by constituting an image forming device so that tension of the belt may be enhanced by action associated with attachment of a belt unit to the image forming device. SOLUTION: The transfer belt unit 1 is inserted and attached to an image forming device main body in the carrying direction of the belt 2, that is, in the direction going toward a driving roller 8 from a fixed roller 3. The shaft of the roller 8 moves in a slot and its distance from the roller 3 is gradually made longer as it advances along a 2nd guiding groove 120. Namely, the belt 2 is gradually tensioned. When the shaft of the roller 3 reaches the edge of a 1st guiding groove 130 and the shaft of the roller 8 reaches the edge of the groove 120, the belt 2 is properly tensioned, and a part of the belt 2 laid between the rollers 3 and 8 reaches an attaching position where it comes in contact with photoreceptor drums 31C to 31BK arranged on a line.

Title: Document copying machine
Inventor: ROBAATO PII SHIIGERU
IPC: H04N1/193
Filed: 1991-07-23
Abstract: PURPOSE: To accurately copy a document end by measuring a distance between an image of an original and a platen surface, obtaining a value indicating a focusing loss of image data from the platen surface based on the distance, and revising and correcting the image data based on the value. CONSTITUTION: In the case of the document copy mode, a height sensor 24 is operated to measure a distance ΔZ (distance between a platen surface 13 and pages of a book) of an object caused by the presence of a filing area 60 apart from an image of a book. In the correction of the image, a correction distance of an image segment in the scanning direction is expressed as Δx/cosθ, based on information from a height profile map, in which Δx is a projected distance of the image segment and θ is a local gradation. Thus, the image of a curved object, while being extended in the scanning direction, is projected on the flat platen surface. The correction such as above is attained by programming properly a processor to apply a correction factor to electric image data from a CCD 22.

For instance, the level ''1'' corresponds to the opening degree of 1-2.5, the level ''2'' the opening degree of 2.5-5, the level ''3'' the opening degree of 5-7, and the level ''4'' the opening degree of 7 or more. As a result, the engine is controlled in an optimal manner at its acceleration.

Abstract: PURPOSE:To accomplish direct overwrite by measuring the moving quantity of an objective lens which is driven by following up the face wobbling of a magneto-optical disk and controlling a magnetic head so that a certain distance is kept between the magneto-optical disk and the magnetic head. CONSTITUTION:Currents whose directions are reverse to each other are applied to two coils 6 and 7 so as to move a movable magnet 1 up and down with the neutral pint as center, and a focusing control current is applied to the coil so as to allow the objective lens 4 to follow up the face wobbling of the magneto-optical disk 10. The moving quantity is obtained by measuring the magnetic field intensity of the movable magnetic field intensity of the movable magnetic by a Hall element 9. The moving quantity of a magnetic head 11 for modulating magnetic field is detected by the same means as the element 9. A control signal generated by taking the position of the objective lens as a reference signal and the position of the magnetic head as a feedback signal is used to drive a magnetic head actuator and the impressed magnetic field intensity on a recording film is kept constant, so that the magnetic field intensity at the position of a laser beam spot is made constant and the direct overwrite and high transfer rate are obtained.
