    摘要: The invention aims to reduce an error occurring due to the mounting condition of an acceleration sensor. In the case of a two-axis sensor, an angle θ is calculated from outputs (x′, y′) that the acceleration sensor produces when known accelerations (x, y) are applied, and the angle θ is stored in a storage device contained in a casing in which the acceleration sensor is housed. In the case of a one-axis sensor, the ratio of the magnitudes of accelerations is stored. The acceleration detected by the acceleration sensor is compensated by using the value stored in the storage device.

    摘要: A movable code plate for an optical encoder is given a light path changing function by forming a series of indentations in one or more portions of one surface of the plate. Since these indentation are sufficiently shallow with respect to the thickness of the movable code plate, sufficient strength of the movable plate is maintained. These indentations can be formed on the surface of the movable code plate without a high accuracy. These indentations may be V-shaped grooves or matted surfaces.

    摘要: An optical rotary encoder simple in construction and capable of easily securing an aligned state of a code plate with a rotating shaft A disk DS and an attachment portion DM of a code plate (6) are formed of an integrated plastic molded product, so that the assembly work for the code plate (6) itself is unnecessary. A lens group is formed in a predetermined region of the disk DS. When a fitting portion RE of a shaft member (20) is press fitted into an insertion hole DE, alignment holding portions (J1 to J3) are deformed plastically to thereby achieve the alignment. The attachment portion DM and the shaft member (20) are fixed to each other by engaging a fixing bolt BL with threaded holes DH and RH. A plurality of alignment holding portions (K1 to K3) may be provided at the outer peripheral surface of the attachment portion DM. In this case, the alignment is achieved by press fitting the attachment portion DM into a fitted portion RF and plastically deforming the alignment holding portions (K1 to K3). The alignment holding portions may be provided so as to be deformed elastically in the radial direction. Also, a tapered fitting structure may be adopted.

    摘要: A mobile code plate manufactured, such as by plastic injection molding, encodes input light by the light path alteration function of a first optical bending portion. This is converted into a first output optical flux by perpendicular incidence and optical transmission at the position of input of a first input optical flux and is then input to a first photodetector element. Since the first optical bending portion arrives at the input position of a second input optical flux, a bent second output optical flux is generated and is likewise input to the first photodetector element. As the mobile code plate rotates, a second optical bending portion arrives at the input position of the first input optical flux. When the first optical bending portion leaves the input position of the second input optical flux, third and fourth output optical fluxes are input to a second photodetector element with the result that an inverted signal is obtained.

    摘要: An optical encoder with a high utilization efficiency of light and easy to manufacture. The optical encoder comprises a conversion device formed in such a manner that lens elements are arranged periodically with a reference pitch IP for converting a beam L emitted from a light source into a plurality of shifting beams MF. The beam L is contracted to a half of the reference pitch IP by the conversion device and goes out as a parallel beam, to impinge on a light receiving section. On a board of the light receiving section there are arranged light receiving elements with a pitch of IP/2. When an object connected to the conversion device is rotated or translated, the position of each lens element changes synchronously and the shifting beam MF scans an arrangement of the light receiving elements. As a result, a ratio of a light amount reaching the light receiving element changes periodically. The resultant electrical signal is processed by a well-known processing circuit.
