2. Description of the Related Art In recent years, a laser pointer is a light spot (spot light) at a desired position such as a sentence or figure projected (or imaged) on a screen or the like by a presenter or presenter at a conference or lecture. A laser pointer that is pointed at is used. In addition, the following is disclosed as an improvement of the conventional spot pointer type laser pointer. Japanese Utility Model Laid-Open No. 61-140315 discloses a laser pointer which can point a desired position on a screen or the like with a light spot of a laser beam made into a parallel light flux. In Japanese Utility Model Laid-Open No. 3-125318, a light spot of a laser beam formed into a parallel light beam indicates a desired position such as a screen, or at least one of a visible light semiconductor laser and a collimator lens is in a plane orthogonal to an optical axis. There is disclosed a laser pointer capable of displaying an underline, a circle, a number, etc. by vibrating a light spot in the horizontal and vertical directions by vibrating at. In Japanese Utility Model Laid-Open No. 125319/1993, a light spot of a laser beam formed into a parallel light beam indicates a desired position on a screen or the like, or a scanning mirror rotatably supported on the optical axis of a visible light semiconductor laser is used. There is disclosed a laser pointer capable of scanning and moving a light spot in the left-right direction to display an underline or the like.

[0003]

However, the above-mentioned conventional structure has the following problems. That is, the light spot of the parallelized laser beam and the underline obtained by scanning in the left / right and up / down directions are excellent for instructing the text projected on the screen, but detailed explanation of the plant diagram and It is impossible to indicate the repair position of the factory equipment concretely and accurately, and there is a problem that it is lacking in convenience and reliability. When marking the reference point on the base of the wall when performing centering, etc. between the walls that are erected relative to each other during construction work, first perform centering with a single laser light spot. However, it is difficult to perform the work with high precision and efficiency, and there is a problem that the workability is poor. Even during nighttime work or in the daytime, in a dark factory or a ship under construction, the instructor must instruct the instructed person with a flashlight and a laser pointer in both hands, which is difficult to explain, lacks safety, and is accurate. However, there is a problem in that it is inconvenient because various instructions cannot be given.

The present invention solves the above-mentioned problems of the prior art, is light and compact, and can irradiate a point mark consisting of an accurate character according to the work, which can be easily and accurately instructed by the instructed person, and is reliable. Providing a laser pointer with excellent operability and workability, and even at night, the instructor can easily point with one hand while irradiating a point mark consisting of an accurate character according to the instruction content, etc., lightweight, compact and convenient The purpose is to provide a flashlight that doubles as a laser pointer and has excellent properties.

m, and more preferably 630 to 640 nm. Particularly, it is preferable that the wavelength of red light with high visual sensitivity is around 635 nm. As the wavelength of the laser light becomes longer than 640 nm, the pattern tends to become darker when the irradiation target is irradiated, and as the wavelength of the laser light becomes shorter than 630 nm, the color of the pattern becomes yellow when the irradiation target is irradiated. Both of these are not preferable, because the point effect tends to be weakened as the wavelength approaches the wavelength of light. The radiation level of the visible light semiconductor laser is preferably class 2 (1 × 10 ⁻³ W) or less in consideration of the effects on the living body such as visual damage and skin damage. The cylindrical lens holder and the cylindrical light projecting portion of the point mark projecting portion increase the light intensity of the laser light that has passed through the aspherical lens, depending on the type of the aspherical lens, and the light emitting portion of the visible light semiconductor laser and the aspherical surface.

You can give explanations and instructions by irradiating various point marks,
That is, an arrow or a finger mark can be used not only to indicate a desired position of a sentence, a figure, or the like projected on a screen or the like in a meeting or the like, but also to emphasize an important point or to explain a charge charging direction such as a charge direction. Can be explained clearly, and the repair position can be clearly indicated in the repair work of various plant equipment, etc. and particularly important points can be emphasized and instructions can be given. The direction of flow of gas etc. can be indicated, and the cross-shaped can clearly indicate the core position and the installation core position in centering work such as civil engineering and construction work, so that the worker can quickly and accurately aim the core position aiming at the intersection. Can be marked, the construction can proceed with high accuracy, and the core position and installation core position can be clearly indicated by the centering work and positioning work such as installation work of various equipment such as transport rolls. The work order can be clearly specified and instructed in various types of work, for example, when each work is performed step by step in various plant equipment, etc. It is possible to improve the workability and reliability, and realize a low-cost laser pointer. Further, the laser pointer / flashlight of the present invention has the following excellent effects. (3) A housing for accommodating batteries and the like, a visible light semiconductor laser provided in a lamp mounting portion of the housing, a projector holding case rotatably mounted in the lamp mounting portion of the housing, A lamp holder formed in the projector holding case; and at least one or more point mark projectors mounted around the lamp holder of the projector holding case facing the visible light semiconductor laser. Since the battery, the visible light semiconductor laser, and the connecting portion for electrically connecting the lamp holder are provided, a point mark projection having a point mark composed of various characters such as arrows, finger marks, cross characters, one character, and numbers With multiple parts, it can be lightweight and compact, and the instructor, instructor, etc. can irradiate accurate point marks at any time according to various tasks to give explanations and instructions. In addition, the explained person and the designated person can instruct the instruction transmission condition without mistake, and can perform prompt and accurate work, improve convenience, workability, reliability, and low cost laser. A flashlight that doubles as a pointer can be realized.
