Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is used by a presenter to guide a viewer's line of sight by indicating a specific position on a bulletin board with a laser beam when conducting a research presentation or performance in front of a large number of audiences. The present invention relates to a portable small laser beam pointer used.

2. Description of the Related Art As is well known, laser beams have directivity,
It has a very good degree of focusing and the property that light does not diffuse. In particular, the semiconductor laser oscillator is small in size and oscillates when a direct current is applied to the PN junction and consumes less power, so that it is easy to drive a battery. For this reason, a battery-driven pencil light type laser beam pointer using a semiconductor laser has been conventionally used.

[0003]

However, in the conventional laser beam pointer, the presenter always had to hold the pointer in order to index a specific portion on the bulletin board. That is, since the conventional laser beam pointer was a mere pencil light type columnar shape, for example, even if it is placed on the podium, if you release your hand, the laser beam will only go in the horizontal direction, and at a specific position on the bulletin board during the performance. I couldn't do that. Therefore, there is a drawback that it is not easy to use.

[0004]

A body for accommodating dry batteries is formed in a tubular shape having at least one side wall flat, and a semiconductor laser beam oscillator is connected to the tip of the body through a flexible tube. The battery power source lead wire of the laser beam oscillator is wired in the flexible tube.

[0005]

Since the body can be stably placed on the podium or the like, the laser beam can be placed in a desired direction by appropriately bending the flexible tube.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a laser beam pointer according to the present invention will be described with reference to the drawings. 1 is 2 AAA batteries
The main body 1 is a cylindrical body that can be housed in series, and the side wall 3 is flat and has a U-shaped cross section. Reference numeral 4 denotes a cap screwed to one end of the body 1 so that it can be opened and closed when the battery is replaced. Reference numeral 5 is a pin provided on the outer periphery of the body 1 for engaging with a pocket of clothes when carrying the battery. Also serves as a switch.

Reference numeral 6 is a semiconductor laser beam oscillator, and the laser beam oscillator 6 is connected to the tip of the body 1 with a flexible tube 7 interposed. The flexible pipe 7 is made of a bellows-shaped metal pipe, and is flexible so that the bent state is maintained when it is bent by a hand, and is a member that has been conventionally used for a tap outlet of tap water or the like.
Reference numeral 8 denotes a light emitting port of the laser beam oscillator 6, 9 denotes a power source terminal of the laser beam oscillator 6, and a lead wire 10 of a battery power source connected to the power source terminal 9 is wired in the flexible tube 7.

In the laser beam pointer constructed as described above, the body part 1 can be stably placed on a flat surface such as a podium by setting the one side wall 3 on the lower side. Therefore, the flexible tube 7 should be bent appropriately. Thus, the laser beam emitted from the light emitting port 8 of the laser beam oscillator 6 can be radiated to a desired portion on the bulletin board as shown in FIG.

[0009]

As described above, the laser beam pointer according to the present invention can be installed so that the laser beam is directed in a desired direction even if it is not held by hand.
There is a beneficial effect that it is easier to use and can be conveniently used.
