Embodiment Construction

[0043] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0044] exist figure 1 A schematic perspective view of the laser pointer according to the present embodiment is shown in figure 2 The exploded perspective view of its main parts is shown in . In these figures, the laser pointer 10 is configured to include: a housing main body 11, a semiconductor laser device 12 accommodated in the housing main body 11, a holding member 13 located on the outer peripheral side of the laser device 12, and the holding member 13. 13 supports the lens holder 15 and the rotating member 16, and the linkage mechanism 17 arranged between the rotating member 16 and the lens holder 15.

[0045] The casing main body 11 is formed in an elongated cylindrical shape (for example, about ten millimeters in diameter). In the case body 11 of the figure 1 On the middle right end side, that is, on the rear end side, a tail plug 20 having a ring ...

Abstract

A laser pointer capable of miniaturization is provided. A laser pointer (10) accommodates a semiconductor laser device (12) in a casing body (11), and can project laser light emitted from the laser device (12) from a projection unit (58) to form predetermined indication marks. The laser pointer (10) includes a lens holder (15) mounted with multiple lenses (46, 47), and the lens holder (15) is arranged between the laser device (12) and the projection part (58). A central axis (L) of laser light emitted from a light emitting surface (12A) of a laser device (12) is set to coincide with a central axis of a housing main body (11). The projecting part (58) is provided at the rotation center position of the rotation member (16) mounted on the housing main body (12), and the rotation center of the rotation member (16) is set to coincide with the central axis (L) .

Description

technical field [0001] The present invention relates to a laser pointer, and more specifically, to a laser pointer capable of displaying various indication marks with laser light. Background technique [0002] In academic conferences, briefing sessions, etc., projection of materials, etc. is performed on a screen set at a position away from a lecturer, etc., and a laser pointer for indicating a corresponding position on the screen is used. [0003] A well-known laser pointer has a structure in which a semiconductor laser device and a battery are housed in a case extending in the longitudinal direction, and laser light is emitted from a projection part provided on one end of the case by operating a switch provided on the outer side of the case. . A laser pointer is known (for example, refer to Patent Document 1) in which various marks such as arrows are used as index marks in addition to dots, and these marks can be switched as necessary. [0004] Patent Document 1: Japanes...
