And the 2nd fork is divided 120 front ends, is the past terminal number the 3rd to the 5th rod type lens array 6c...... that is configured in the stick shape lens array primitive plate 8 on the off-position is pushed towards worktable 92.By such structure, carry out from stick shape lens array primitive plate 8 cut-out/separation rod type lens arrays 6, even if under the state of only surplus latter two rod type lens array 6 on the stick shape lens array primitive plate 8, also stick shape lens array primitive plate 8 is flatly remained on the given position in the same old way, can cut off exactly.

The following describes the action of stick shape lens array primitive plate shearing device.Put stick shape lens array primitive plate 8, make cylinder 102 work, send stick shape lens array primitive plate 8 to, be connected to positioning element 112 up to its front end to cut-out portion 88.When by sensor 114 positioning element 112 that detected stick shape lens array primitive plate 8 front end butts, cylinder 102 is stopped work, and the position of releasing parts 96 is locked.

Then, upper cutter 110 moves to the approximated position near lower cutter 108, thereby the rod-shaped lens part of exposing between the rod type lens array 6a of stick shape lens array primitive plate 8a front end and the 2nd the rod type lens array 6b 1 ' is cut off.Fallen down by the foremost rod type lens array 6a that gets off from stick shape lens array primitive plate 8a cutting, be housed in the recoverer (omitting among the figure) that is configured in the below.

Then,, make cylinder 102 work again, send stick shape lens array primitive plate 8 to, be connected to positioning element 112 up to its front end when upper cutter 110 leaves lower cutter 108 and arrives when leaving the position.By carrying out above-mentioned action repeatedly, the operation of cutting off rod type lens array 6 from stick shape lens array primitive plate 8 continues to carry out.In the present embodiment, be to utilize mechanical arm to supply with stick shape lens array primitive plate 8 to worktable 92.But, also can lean on other feed mechanisms or operator to supply with.

According to said structure, because pushing the back timber 98 of stick shape lens array primitive plate 8 is that bar 100 swingingly connects relatively, when so even stick shape lens array primitive plate 8 tiltedly has been placed on the worktable 92, can not occur single state of pressing a side yet, stick shape lens array primitive plate 8 can be pressed assigned direction and release.

Also have, when cutting off rod-shaped lens part 1 ', because of the retroaction to the cut-out of cutting knife 108 and 110, rod-shaped lens 1 is understood in arrow L direction and is moved.But, because the fitting 104 that is imposed elastic force by spring 106 is installed on the back timber 98 of pushing stick shape lens array primitive plate 8 rear ends, so the motion of stick shape lens array primitive plate 8 is absorbed by spring 106.And the impact of stick shape lens array primitive plate 8 front ends during with positioning element 112 butts also absorbed (buffering) by this spring.Therefore, can suppress the position deviation of stick shape lens array primitive plate 8 because of the retroaction of cutting off is produced.

Also have, because positioning element 112 is configured to: the upper section of butt stick shape lens array primitive plate 8 front ends is the front of substrate 2 (4) of upside of the rod type lens array 6a of front, even so last time cut rod-shaped lens part 1 ' front end outstanding from stick shape lens array primitive plate 8 front ends, also can position exactly, not influenced by it.

About the shape of pressing plate, be not limited only to shape described in the foregoing description, so long as possess can push at least in the stick shape lens array primitive plate before the getting final product of several the 2nd these effects of rod type lens array.

Also have, the shape of the cutting knife that is used to cut off also is not limited only to embodiment and was described.

The present invention is not limited only to the foregoing description, in the scope of the item that claim of the present invention is put down in writing all changes, distortion can be arranged.
