Only the photoresist 30 covering the core 12 remains after the development. The light reflecting body 11 of aluminum is then stuck by vapor deposition, sputtering method, etc., over the entire surface of the light incident port side end face 10a. The photoresist 30 covering the core 12 is finally removed together with the aluminum 11 stuck thereon, by which the optical waveguide array 10 formed with the reflecting surface in the part exclusive of the core 12 part is obtd. The exact incidence of the light on the inside of the core 12 of the optical waveguide array 10 is thus possible.

IPC: B65B43/18
Filed: 1991-10-25
Abstract: PURPOSE:To provide a bag supply device that allows bag supply work to be performed always properly, by furnishing the device with a sensor which identifies whether a bag in a bag container is normal or reverse position in the longitudinal direction and with a rotating mechanism which rotates by a predetermined angle suckers which suck and lift the bag, and by controlling the rotating mechanism based on an identification mark for the sensor. CONSTITUTION:When bag supplying action is started, suckers 9a and 9b descend, touch the uppermost bag (a) of those laid in a bag container, sick the bag securely, and lift the bag slightly. At this time, a photoelectric sensor 11 identifies a pattern or a color marked on the surface of the bag (a) to determine whether the bag is in the normal or reverse direction. If the bag (a) is judged to be in the reverse direction, a signal is sent to drive a rotating cylinder 12. The rotating cylinder 12 rotates the bag (a) by 180 degrees by means of the suckers 9a and 9b to the normal direction, then delivers the bag (a) to a grasping mechanism 10. Therefore, if bags are different in thickness between both sides in the longitudinal direction, they may be laid in opposite directions one after another or at an interval of a predetermined number of bags. This allows to increase the maximum number of bags that can be stored and to maintain the upper surface of the uppermost bag approximately horizontally.
