An image measurement apparatus, which functions as a non-contact profile-measuring device, includes: an image sensor as an image pick-up device; a variable focal length lens (liquid lens unit) disposed on an optical axis extending from a workpiece to the image sensor; and a controller (image-pickup lens controller and image measurement processor) configured to control the variable focal length lens and process a detected image by the image sensor. The image measurement apparatus, which also functions as a non-contact displacement-detecting device, includes: an image sensor; a variable focal length lens (liquid lens unit) disposed on an optical axis extending from the workpiece to the image sensor; and a controller (displacement-detection lens controller and profile measurement processor) configured to control the variable focal length lens and a detected image by the image sensor.

A telecentric lens optical system includes: a front lens group; a rear lens group having a front focal point coinciding with a rear focal point of the front lens unit; and diaphragm mechanisms, each of which is disposed at a position where the rear focal point of the front lens unit and the front focal point of the rear lens unit coincide with each other. One of the front lens group and the rear lens group is provided by a plurality of variable magnification lens groups. The diaphragm mechanisms are provided corresponding to the variable magnification lens groups, respectively. A magnification switching mechanism is provided to selectively move a pair of one of the variable lens groups and one of the corresponding diaphragm mechanisms to be disposed on an optical axis of the other of the front lens group and the rear lens group.

Telecentric lens system and vision measuring instrument

A bright and dark field switching device, according to the present invention, comprises a glare-proof filter and a condenser lens for a dark field, a guide mechanism , and a switching mechanism . The glare-proof filter and the condenser lens for a dark field are arranged on both sides with an optical path L of an illuminating optical system interposed therebetween. The guide mechanism holds the glare-proof filter and the condenser lens for a dark field such that they can be moved to the optical path L and can be returned from the optical path L. The switching mechanism moves the glare-proof filter and the condenser lens for a dark field to the optical path L and returns them from the optical path L. Further, the switching mechanism moves the glare-proof filter together so as to position the same on the optical path L only when returning the condenser lens for a dark field from the optical path L.

It is provided an automatic MDF control system comprising: a plurality of matrix boards provided with openings in locations where a plurality of first wires and second wires cross without electrical connections; a robot which inserts electrically conductive connecting pins into the openings and connects the first wires with the second wires where the pins are inserted; a path data conversion unit converting connection requests from an operating terminal into path data having a plurality of addresses of the openings; a robot command conversion unit receiving the path data and converting the path data into robot commands for controlling activity of the robot as a distance moved by the robot moving between the plurality of addresses being reduced by a selected sequence of the converted path data; and a robot control unit controlling the activity of the robot based on the robot commands. In this way, when path data is converted into robot commands, the addresses of the openings of the matrix boards contained in the path data are re-listed as the distance moved by the robot is, for example, as short as possible and therefore wasteful movement by the robot is avoided.

Automatic main distributing frame control system

One matrix board aggregate accommodating two matrix boards is made one unit of a switch. Three of the matrix board aggregates are vertically located, groups of such three vertically-located matrix board aggregates are laterally located and robots are provided between the matrix board aggregates. By providing a number of robots, the switch operation speeds up. The robots are controlled by a control circuit/power supply RMC/POW. I/O cables for connecting an MDF apparatus to an exchange or to lines are provided at the back. In a three-stage switching configuration, by devising the location of primary, secondary and tertiary switches, interconnection between matrix board aggregates can be made using BWBs made of a printed wiring board.

Automatic MDF (main distribution frame) apparatus

A matrix-switch-board unit has two wiring-pattern arrays which are respectively formed in opposite sides of the unit so as to be electrically isolated from and to cross each other, respective through holes extending between and through the crossing portions of the wiring pattern arrays on the opposite sides of the unit. A connection pin inserting and extracting device automatically and selectively inserts a connection pin into a selected one of the through holes for interconnecting the corresponding opposed, crossing pattern portions and extracts a connection pin from a corresponding one of the through holes for disconnecting same. Pivotally mounted toggle arms of the device have respective ends with laterally extending hook portions in opposed relationship and are rotatable in a first sense to engage a pin between the hook portions and in an opposite sense to release a connection pin engaged thereby.

Automatic distribution equipment for connecting and disconnecting lines includes a frame body, a plurality of matrix-switch-board units arranged in the frame body in a stack formation, and a robot provided in a side of the frame body. Each of the matrix-switch-board units has two wiring-pattern arrays which are respectively formed in opposite sides of each of the units so as to be electrically isolated from each other and to cross each other, wherein when a connection pin is inserted into one of through holes formed at cross points of the two wiring-pattern arrays, respective wiring patterns of the two wiring-pattern arrays are connected to each other. The robot moves between two of the matrix-switch-board units, and inserts-and-extracts the connection pin into-and-from a designated through hole to connect-and-disconnect designated lines.
