DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The figures show a preferred embodiment of a device 1 in accordance with the present invention for controlling the emission of a laser beam in a large laser-carving machine 2.
Referring to FIG. 1 and 2, the device 1 includes a portable controller 11 and a cable 12. The portable controller 11, preferably having a handy shape like a pen, is formed with a switch 13 and that is a button switch.
The cable 12 extends between the portable controller 11 and a main unit 21 of the large laser-carving machine 2, as shown in FIG. 4 and 5, and electrically connects the switch 13 of the portable controller 11 with the main unit 21 in such a way that the switch 13 may turn on/off a laser tube provided in the main unit 21. As an important feature of the present invention, the cable 12 should have a length long enough to allow a user holding the portable controller 11 to walk about the main unit 21 of the large laser-carving machine 2.
During adjusting the focus of the laser beam, as shown in FIG. 3 to 5, the user can hold the portable controller 11 with one hand. He/she may press the switch 13 immediately after adjusting the orientation of a reflector situated at one side of the main unit 21 for turning on the laser tube so as to examine whether the beam emitted from the laser tube is focused at a correct position. If it is not, the user may press the switch 13 again after adjusting the orientation of the reflector once more.
From the foregoing, it is apparent that the present invention is advantageous in that:
- 1. It allows the user to turn on the laser tube immediately after adjusting the orientation of the reflector without the need to walk to and from the control panel of the laser-carving machine. It can not only save time but also improve the accuracy of the adjustment; and
- 2. It also allows the user to turn on the laser tube at everywhere around the main unit of the machine.
Although the embodiment together with structures and functions of the present invention has been described in detail, many modifications and variations may be made from the teachings disclosed hereinabove. Therefore, it should be understood by those skilled in the art that any modification and variation equivalent to the spirit of the present invention should be regarded to fall into the scope defined by the appended claims.
