Abstract

This transfer tray is for the insertion and removal of a group of interchangeable keybutton caps which are separable from their associated key buttons and key stems. Transfer tray 1 is made of a nonmagnetic material. Tray 1 contains a plurality of recesses 2 arranged in matrix form and adapted to receive a corresponding plurality of keybutton caps 3. Each keybutton cap 3 has identifying indicia on it and is made of a magnetic material. Caps 3 are held in position in recesses 2 of tray 1 by the magnetic attraction of movable magnets 4. Tray 1, containing caps 3, is placed over an array of plastic keybuttons 5 each of which is fixedly mounted to a metallic key stem 6. Magnets 4 are then moved in the direction of arrow 7 reducing the attraction between magnets 4 and caps 3. Tray 1 can then be removed.

Transfer Tray for Separable Keybutton Caps

This transfer tray is for the insertion and removal of a group of interchangeable keybutton caps which are separable from their associated key buttons and key stems. Transfer tray 1 is made of a nonmagnetic material. Tray 1 contains a plurality of recesses 2 arranged in matrix form and adapted to receive a corresponding plurality of keybutton caps 3. Each keybutton cap 3 has identifying indicia on it and is made of a magnetic material. Caps 3 are held in position in recesses 2 of tray 1 by the magnetic attraction of movable magnets 4. Tray 1, containing caps 3, is placed over an array of plastic keybuttons 5 each of which is fixedly mounted to a metallic key stem 6. Magnets 4 are then moved in the direction of arrow 7 reducing the attraction between magnets 4 and caps 3. Tray 1 can then be removed. Caps 3 remain on keybuttons 5 because of the magnetic attraction between the magnetic key caps and their associated metallic key stems 6. Then the empty tray 1 can be placed over the keybuttons and magnets 4 moved into their pickup positions to effect removal of caps 3. Another group of key caps can then be deposited onto the keybuttons.
