Image control board

A board providing precise registration and alignment of a plurality of planar work pieces each having a plurality or registration holes therein comprising:

• a. a planar board;
• b. a plurality of self-contained spring biased retractable pins mounted on said board, said pins adapted to be received within the registration holes of the work pieces, wherein each of said pins includes a barrel having an end aperture, wherein said pin exhibits a non-circular shape when viewed end-on along said pin axis, and wherein each of said pins is mounted in said barrel to project through said end aperture yet permit non-rotational movement of said pin in said barrel and in the plane of the board;
• and
• c. means for rigidly securing each barrel to said board.

A board providing precise registration and alignment of a plurality of planar work pieces each having a plurality of registration holes therein comprising:

• a. a first planar member;
• b. a second planar member adhered to said first planar member, said first and second planar members each having a plurality of aligned holes;
• and
• c. a plurality of retractable pins mounted within aligned holes of said first and second planar members, each of said pins projecting through an aperture of a barrel and adapted to be received within an aligned hole pair in said first and second planar members and having a barrel diameter substantially the same as the diameter of said aligned hole pair, a radially extending flange fixed to said barrel and a diameter of said flange being greater than the diameter of said aligned hole pair and said flange being sandwiched between said first and second planar members, wherein ones of said pins exhibit a non-circular shape when viewed end-on along a pin axis perpendicular to said first and second planar members, and wherein said non-circular pins are mounted in said barrel to permit non-rotational movement of said non-circular pins said barrel in the plane of the board.

A board providing precise registration and alignment of planar work pieces, each work piece having a plurality of registration holes therein, comprising:

• a. first and second substantially rigid board members adhered together and having a plurality of aligned holes;
• b. a plurality of pins mounted on said board members and received within said holes and projecting from said board members along a pin axis perpendicular to said board members, said pins adapted to be received within the registration holes of the work pieces;
• and
• c. mounting means for securing at least one of said pins for multidirectional movement in the plane of the board members while retaining said pin axis perpendicular to said board members to ensure registration and alignment of the multiple work pieces with respect to each other, wherein a barrel having an end aperture is rigidly secured to said board members, wherein said pin exhibits a non-circular shape when viewed end-on along the pin axis, and wherein said pin is mounted in said barrel to project through said end aperture yet permit non-rotational movement of said pin in the plane of the board.

A floating pin adapted to be mounted on a board in a manner to permit multidirectional movement of the pin in the plane of the board comprising:

• a. a barrel having an end aperture;
• b. a sleeve having an end aperture;
• c. a pin member slidably received within said sleeve and projecting from said sleeve and barrel;
• d. spring means for urging said pin member into an extended position projecting through the end apertures of said sleeve and barrel;
• e. means for retaining said spring means and said projecting pin member in said sleeve and said sleeve within said barrel;
• and
• f. wherein said pin member is non-rotationally movable in the end aperture of the barrel in the plane of the board.
