A recording and/or reproducing apparatus for a disc shaped recording medium having a first recording region in which an information signal is recorded using pits and a second recording region in which an information signal is recorded using a magneto-optical method includes a rotational driving unit, a servo apparatus and a controller. A head moves between the first and second recording regions of the disc-shaped recording medium and records and reproduces information signals to and from the disc-shaped recording medium. The rotational driving unit rotates the disc-shaped recording medium at a constant linear velocity by using the output signal outputted from the head. The servo apparatus generates a servo signal according to an error signal generated using the output signal from the head and carries out servo control on the head and the rotational driving unit. The controller determines which of the first or second regions of the disc-shaped recording medium the head is in based on the output signal from the head and then uses this determination result to control the servo apparatus.

A developing device for an image forming apparatus and using a single component type developer, i.e., toner, has a developing roller, a doctor blade, and an elastic intermediae roller. The developing roller and intermediate roller contact each other and rotate in the same directions such that they move in opposite directions at the position where they contact each other. The developing roller is provide with a surface roughness of Rz 10 .mu.m or less in terms of ten-point mean value as prescribed by JIS (Japanese Industrial Standards) in order to deposit an adequate charge on toner.

A system for calculating a movement direction and position of a movable object such as an unmanned vehicle running within a factory and a method therefor are disclosed in which an image pick up camera such as a video camera photographs a background of the movable object to generate a background two-dimensional image. Positions of vanishing point and side ends of a passage on which the movable object is to move are derived from the background photographed two-dimensional image. The movement direction of the movable object is derived from the detected vanishing point. Distances of the movable object from both sides ends of the passage are derived on the basis of the detected vanishing point and positions of side ends of the passage. the movement direction and position of the movable object thus detected are used to control movement of the movable object. The vanishing point is detected on the basis of edge directions at all points constituting and edge on the background two-dimensional image.

The present invention relates to an optical reader for scanning a surface to be scanned by using information beam ray such as laser beam ray and optically reading a recorded information such as bar code recorded in the surface to be scanned. The optical reader is constituted such that optical beam emitted from a light source is reflected on a first rotary multiface mirror to scan on a surface to be scanned, and information beam reflected on the surface to be scanned is reflected on a second rotary multiface mirror to guide to an opto-electric transforming means. A scanning optical path for permitting the optical beam from the light source to pass therealong is formed independently from a reflecting optical path for permitting the information beam from the surface to be scanned to pass therealong. A condensing lens system including a bore diameter large enough to cover the scanning optical path and reflecting optical path as well as a single optical axis is disposed between the surface to be scanned and the first and second rotary multiface mirrors.

A cleaning member includes a core bar, an elastic coating layer, and high-friction coefficient parts provided on both ends of the cleaning member. The high-friction coefficient parts include an elastic material. Outer peripheries of the high-friction coefficient parts are inclined with respect to an axial direction of the core bar. The cleaning member is roller-shaped and is configured to clean a surface of a roller member to be cleaned in contact therewith. A charging device and a process cartridge also include the cleaning member.

A magnetic sensor is constituted using magnetic sensor chips mounted on stages supported by interconnecting members and a frame having leads in a lead frame. Herein, the stages are inclined upon plastic deformation of the interconnecting members. When the frame is held in a metal mold and the stages are pressed, the interconnecting members are elastically deformed, so that the magnetic sensor chips are bonded onto the stages placed substantially in the same plane and are then wired with the leads. Thereafter, the stages are released from pressure, so that the interconnecting members are restored from the elastically deformed states thereof. When the magnetic sensor chips are combined together to realize three sensing directions, it is possible to accurately measure three-dimensional bearings of magnetism, and the magnetic sensor can be reduced in dimensions and manufactured with a reduced cost thereof.

In recording materials of a video program or the like, the video materials are efficiently and optimally acquired so that processing steps in and after an editing step subsequent to a recording step can be reduced. A recording support information (metadata) on a schedule of and a performer for an imaging operation, and the like, which are determined in advance is recorded in a first recording medium 16 by a program constitution input device 100. The first recording medium 16 is inserted in to an imaging device 200, materials to be recorded are classified and confirmed based on the metadata, and the materials which can constitute a desirable program as potentially as possible are acquired in the recording operation.

A lead frame includes a frame body defining an internal region, a plurality of leads extending from the frame body, and first and second stages that are disposed in the internal region. The first and second stages are sloped and are parallel to a first line along which a primary stream of a molten resin runs, so that slope angles of the stages are not substantially changed by the injection of the molten resin into the cavity.

A physical quantity sensor includes a pair of physical quantity sensor chips that are inclined with respect to the bottom of an exterior mold package whose side surfaces are each inclined in a thickness direction by an angle ranging from 0° to 5° and are formed in proximity to the outer ends of the physical quantity sensor chips. It is possible to realize the inclination of stages without using molds, wherein absorption devices are used to absorb prescribed portions related to stages, which rotate about axial lines and are thus inclined with respect to a prescribed base. In manufacturing, a thin metal plate having a plurality of lead frames is placed on a base delimited by a clamp; then, intersecting points of intermediate portions formed between the lead frames are subjected to pressing so as to realize the inclination of stages.
