The finished OK product and the NG product that has not been engraved can be discharged separately, and an arrangement that is advantageous in terms of space can be achieved.

  In other words, even if the engraved OK product needs to be accommodated more than the NG product which has an error and has not been engraved, the OK tray 39 has a relatively larger vertical width than the stacker slide 39, and the image engraving unit The OK product and the NG product can be reasonably accommodated on the lower side of 7 without increasing the space.

  The discharge guide 35 is arranged along the vertical direction, the upper and lower ends are curved, the upper end cooperates with the image engraving unit 7, and the sheet engraving medium can be received from the image engraving unit 7, and the lower end is A main panel 217 made of a panel constituting the first discharge path A and a curved panel which is disposed to face the upper end of the main guide 217 and can receive a sheet-shaped engraving medium from the image engraving unit 7 in cooperation with the image engraving unit 7. And an inlet guide 219 made of a panel and a branch guide 223 made of a panel which is arranged to be branched into the upper and lower intermediate portions of the main guide 217 and constitutes the second discharge path B.

  Accordingly, the sheet-shaped engraving medium discharged from the image engraving unit 7 is received between the curve of the upper end of the main guide 217 and the curve of the entrance guide 219, and is guided between the main guide 219 and the intermediate guide 221 and passes through the flag 225. The guide of the sheet-shaped engraving medium guided by the main guide is then selectively returned to the second discharge path B side by the branch guide 223 or as it is guided to the first discharge path A side. It is possible to ensure that this is performed along a panel such as 217.

[Others]
The sheet-like medium discharge device according to the embodiment of the present invention is not limited to that used in the automatic continuous image engraving device 1. Accordingly, any processing unit that processes a sheet-like medium and carries it out in the surface direction can be applied not only to the image engraving unit 7 but also to a processing unit that performs printing, transfer, laser processing, and the like.

  The vertical direction for guiding the sheet-like medium is not limited to the vertical direction, and includes the vertical direction in the inclined direction.

  As a form for processing the sheet-like medium and carrying it out in the surface direction, a sheet-like engraving medium of A4 size or the like is carried out and carried in the long direction, but it can also be carried out and carried out in the short direction. .

  An OK product storage unit such as an OK tray 37 may be connected to the first discharge path A, and an NG product storage unit may be connected to the second discharge path B.

  The OK product storage unit and the NG product storage unit need only be arranged vertically, and the vertical arrangement of the OK tray 37 and the stacker slide 39 can be reversed.

  It is also possible to connect the lower end of the main guide 217 to a processing unit such as the image engraving unit 7 and connect the upper end to the stacker slide 39 or the OK tray 37 to discharge the sheet-like medium upward.

  The main guide 217 and the like are only required to be able to guide a sheet-like medium, and are not limited to being made of a panel, and may be constituted by a hollow guide body.
