    Abstract: An encoder that can measure displacement with high accuracy by canceling out the effects of external noise is provided. The encoder includes a rotor, a stator and a calculation unit. The stator has an even number of detectors that read the graduations and output a signal. The calculation unit has a phase calculation unit that calculates the phase based on the signals output by the detectors, and an averaging unit that averages the phase calculated by the phase calculation unit. The even number of detectors are each located at a position displaced by an integer multiple of the period of the graduations along the measurement direction from the other adjacent detectors.
    The first signal output by half of the detectors and the second signal output by the other half of the detectors to have opposite polarity at the input to the phase calculation unit.

    Abstract: A method for specifying a position through touch input in a screen displayed on a touch panel display. The position is specified by acquiring an initial contact position with the touch panel display, displaying a position displaying cursor in a position according to the initial contact position, displaying the position displaying cursor in the position according to the initial contact position during the period for which the contact position sensing continues until the distance from the initial contact position to the contact position reaches a predetermined distance and terminating the display of the position displaying cursor where the contact position sensing is terminated before the distance reaches the predetermined distance, and displaying the position displaying cursor in such a way that the position displaying cursor follows movement of the contact position after the distance reaches the predetermined distance.

    Abstract: A surface texture measuring machine includes a display section, a touch panel arranged on the display section, a key group, a display control section that causes a first setting screen to be displayed on the display section, a setting section that creates a measurement condition in accordance with an input operation on the first setting screen through the touch panel, a storage that stores the measurement condition, and an input control section that switches a state of the touch panel between a disabled state and an enabled state. When the touch panel is in the disabled state, the display control section causes a second setting screen to be displayed on the display section in accordance with the input operation through the key group and the setting section reads the measurement condition from the storage in accordance with the input operation on the second setting screen through the key group.

    Abstract: A measuring device includes a rotary encoder having a rotary scale and a plurality of detection portions, and a control device. The rotary scale are arranged around a rotation axis and has a scale pattern in which a plurality of patterns are arranged along a circumferential direction. The plurality of detection portions are arranged around the rotation axis, and reads the plurality of patterns from the scale pattern. The control device causes one or some detection portions to perform a first reading of the plurality of patterns at a first timing, causes another or other detection portions different from the one or some detection portions to perform a second reading of the plurality of patterns at a second timing different from the first timing, and calculates a measurement result based on a first reading result of the first reading and a second reading result of the second reading.

    Abstract: An inductive type position encoder includes a scale, a detector portion and a signal processor. According to one aspect, field generating elements and sensing elements of the detector portion are provided on opposite sides of the scale such that at least part of the scale is between the field generating elements and the sensing elements (transmissive configuration). According to another aspect, the scale comprises a periodic scale pattern including signal modulating elements that are disposed along a scale direction, which is not parallel to a measuring axis direction of the encoder and is slanted at a scale angle relative to the measuring axis direction, such that there is a corresponding y-direction displacement for a given x-direction displacement of the encoder. These aspects of the disclosure make it possible to design a very compact inductive type position encoder, including one capable of indicating an absolute position along the scale.

    Abstract: A small-sized measuring device includes a position detector that is provided on a main body and detects the position of an object to be measured, a photosensor, and a central control unit that controls overall operation. The photosensor is configured to function at least as an input device configured to accept a base-point setting instruction from the user. The central control unit, when accepting the base-point setting instruction from the user through the non-contact input sensor, performs a base-point setting step of setting the position of the object to be measured detected by the position detector as a base point, and performs a measurement step of measuring the position of the object to be measured as a relative position from the base point.
