BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laser pointer used for presentation and the like and pointing to a desired location by laser light.

In a presentation made at a conventional meeting or the like, in order to indicate a desired location of a display screen, a laser pointer which can easily point to a place far away from the user by a laser beam is used in place of the indicator rod previously used. . Among them, pen-type laser pointers are particularly used because they are easy to carry and easy to handle. In addition, the laser pointer is not only a function of pointing a laser, but also a function of a pointing device of a personal computer, for example, by scrolling a presentation screen in order to be able to preferably perform a presentation using a personal computer which is becoming a mainstream. It has also been proposed to provide a function of wirelessly operating a personal computer, for example (see Kokuyo 2005 Office Supply, Kokuyo Co., December 16, p.317).

As shown in Fig. 8, the pen-type laser pointer P1 has a function of operating an irradiation unit for emitting laser light inside the pen-shaped case 100, an operation for emitting a laser, a personal computer, or the like. The board | substrate 500 equipped with the operating part X which is operated manually, such as an electronic component and buttons, a dial, and the like, and the power source, such as a single battery, is built. And the board | substrate 100 is the case 100 in the state supported by the resin part J as a special member so that the board | substrate 100 may not bend through the operation part X by manual operation, as shown in the said figure. It is attached to).

Here, if such a special member is not present and the substrate is not sufficiently supported by the case, the electronic component mounted on the substrate may come into contact with another part in the case.

Moreover, by supporting a board | substrate in the resin part which is a special member, also about the assembly process of a laser pointer, two processes of inserting a resin part into a case after making the resin part support the board | substrate become an essential process. have. Such a special member and the two processes mentioned above occupy a part of manufacturing cost of a laser pointer both in terms of component cost and assembly cost.

SUMMARY OF THE INVENTION The present invention focuses on such inadequacies and provides a laser pointer that can effectively suppress manufacturing costs while ensuring good operation.

In order to achieve the above object, the present invention seeks the following means. That is, the laser pointer according to the present invention includes a pen-shaped case, an operation unit for manually operating from the outside of the case, and a substrate supporting the operation unit in such a manner that the operation force acts in the thickness direction when the operation unit is operated. A laser pointer, which is provided, is integrally provided with a regulating means for restricting the movement of both side edges of the substrate in the circumferential direction.

Here, the form of the restricting means may be a groove or a spring formed in the inner surface of the case, and a granularity formed in the inner surface of the case. In addition, "regulating" the movement in the thickness direction is not limited to the one configured to be unable to move in the thickness direction, and is a concept including only controlling movement of the substrate when pressing the operation button. In addition, the operation portion is not limited to being operated in direct contact with the user's finger. For example, the operation force of the user may be transmitted through the case such that the operation force is indirectly applied through the separate cover, or the part is flexibly configured.

In such a case, since there is no need to provide a special member for fixing the substrate inside the case, the number of parts constituting the laser pointer can be effectively reduced. In addition, since the movement in the thickness direction of both side edges of the substrate is regulated by the restricting means, for example, the electronic circuit mounted on the substrate can be effectively prevented from moving.

In particular, in order to provide a function as a guide guide when mounting the substrate to the regulating means so as to further simplify the assembling process of the laser pointer, it is preferable to provide the regulating means from the insertion start position to the insertion end position to insert the substrate. .

Here, the regulating means may be provided continuously from the insertion end of the substrate to the insertion end, or may be provided intermittently.

Moreover, in order to reliably position in the thickness direction of a board | substrate, it is preferable to comprise the control means so that movement in the thickness direction of a board | substrate is impossible.

As a specific structure of the regulation means for improving the design freedom in arranging a board | substrate, it is preferable to comprise the regulation means by the groove | channel or groove formed by changing the thickness of a case. The grooves may be grooves formed by thinning the case according to the thickness of the substrate, or may be grooves formed between the springs by forming two springs to restrict the substrate from both sides. And if the case is made into a cylindrical shape, the case strength can be set high.

Moreover, as another structure which can implement | regulate a regulation means, if effectively avoiding performing special processing for providing a regulation means, the form which has a pair of opposing standing angles formed in the inner surface of a case as a regulation means can be mentioned. .

A pair of support grooves 18 and 18, which are the restricting means Z, are formed from the front end of the case 1 to the base end. The pair of supporting grooves 18, 18 are formed at positions facing each other, that is, at a position where the case 1 can be divided into two in the radial direction, and the separation distance between the supporting grooves 18 between the cases It is made to be slightly larger than the inner diameter of (1). In addition, a pair of grooves 19 opposed to each other on a straight line that can be substantially orthogonal to the virtual straight line connecting the pair of support grooves 18 and 18 are formed in the long axis direction of the case 1. These grooves 19 are conveniently formed at the time of forming the case 1 (during drawing process), and do not serve to support the first substrate 5. In this embodiment, approximately one center of the groove | channel 19 which does not serve to support the 1st board | substrate 5, and each center of the said hole 11, 12, 13, 14 and the window part 15 correspond substantially. I'm making it.

As shown in FIG. 1 and FIG. 2, the tip side cap member 2 is formed in the outline cylinder shape opened only to one direction side, and is comprised so that fitting to the tip part of the case 1 on the open end side is possible. Moreover, the through-hole 22 for laser beam irradiation is formed in the front-end | tip part of the front-end | tip cap member 2. As shown in FIG.

It is equipped with. The inner circumferential surface of the terminal member 32 is configured to be screwable to the base end of the case 1.

As shown in Fig. 4, the internal installation unit 4 mainly includes a first substrate 5 which is a substrate on which a circuit for communicating with a predetermined receiver is provided, and a second substrate on which a circuit for emitting red laser light is provided ( 6) and the wavelength conversion module 7 which converts a red laser into a green laser are provided integrally. Specifically, a spacer 8 made of, for example, a synthetic resin material and a spring member 9 functioning as a terminal of the battery B are integrally formed at the proximal end of the first substrate 5 by appropriate mounting means, respectively. I attach it. Moreover, the wavelength conversion module 7 (and irradiation part) is provided in the front-end | tip part of the 1st board | substrate 5. As shown in FIG.

The first substrate 5 is a schematic plate whose dimensions between both side edge portions 5a and 5a approximately coincide with the separation distance of the pair of supporting grooves 18 and 18 formed in the inner peripheral surface of the case 1. It is in shape. The first substrate 5 is a receiver connected to an information processing device such as a personal computer (not shown), in addition to the laser switch 51 for operating laser light emission (a receiver for receiving electromagnetic waves in the 2.45 GHz frequency band in this embodiment). ) Is installed to communicate with. Specifically, the components of the page back switch 52, the page next switch 53, and the mouse switch 54 are provided on the first substrate 5 in this order from the proximal side, and the switches 52, 53, When a pressing force is applied to 54, a predetermined signal corresponding to each of these switches 52, 53, and 54, that is, a screen displayed on a display image (not shown) is returned to the previous screen. A screen return signal for switching, a screen turning signal for switching the screen displayed on the display screen to the next screen, and a mouse pointer movement signal for moving the mouse pointer displayed on the display screen in a predetermined direction. Is transmitted to the receiver using electromagnetic waves. In this embodiment, as a communication method, an RF (Radio Frequency) method using electromagnetic waves in the 2.45 GHz frequency band is adopted, and communication is possible between the receiver and the receiver within approximately 10 meters.

Here, in this embodiment, the laser switch 51, the page back switch 52, the page next switch 53, and the mouse switch 54 each independently form an operation unit according to the present invention.

The 2nd board | substrate 6 sets width | variety dimension and long-axis dimension smaller than the 1st board | substrate 5, and the circuit for emitting a red laser is provided in this 2nd board | substrate 6. As shown in FIG. Further, control of whether or not the laser is emitted is performed by whether or not a reduction force is applied to the laser switch 51 provided on the first substrate 5. Moreover, the light-emitting body 55 which lights up in association with the light emission of a laser beam is provided in the 1st board | substrate 5. In this embodiment, the light emitting body 55 is provided at the front end side more than the installation location of the mouse switch 54. In addition, the 2nd board | substrate 6 and the 1st board | substrate 5 mentioned above are laminated | stacked in the state which separated predetermined distance in the thickness direction in the state which made the center axis | shaft along each long-axis direction coincide, and are electrically connected.

The wavelength conversion module 7 converts the 808 nm red laser emitted by a semiconductor laser light emitting device (not shown) into 1064 nm, and passes the laser through a wavelength conversion crystal (not shown) to a wavelength of 532 nm. It is irradiating the converted green laser.

Next, the assembly procedure of the laser pointer P which consists of such components is demonstrated using FIG. 2, FIG. 4, and FIG.

First, the laser switch cover C1 in the laser switch hole 11, the page back switch hole 12, the page next switch hole 13, and the mouse switch hole 14 formed in the case 1, respectively. , Page back switch cover (C2), page next switch cover (C3), and mouse switch cover (C4) are attached. In addition, in FIG. 5, illustration of each switch cover C1, C2, C3, C4 and the lens body 16 which are attached to each hole 11, 12, 13, 14 and the window part 15 is abbreviate | omitted. .

Subsequently, as shown in FIG. 5 (a), the side edge portion 5 a of the first substrate 5 is inserted into the support groove 18 provided in the inner circumferential surface portion of the case 1 to be mounted inside. The unit 4 is inserted from the insertion start position Z1 on the front end side of the case 1. And as shown in FIG. 5 (b), the inner mounting unit 4 is moved to the case 1, guiding the side edge part 5a along the longitudinal direction of the 1st board | substrate 5 along the support groove 18. As shown in FIG. Slide in the long axis direction. In this embodiment, as shown to FIG. 5 (c), when the front-end | tip part of the case 1 and the start-end part of the coil-shaped part of the antenna A are set to the predetermined position which is substantially corresponded, the side edge of the 1st board | substrate 5 The position in the support groove 18 which is in contact with the position biased toward the most proximal end of the portion 5a is set as the insertion end position Z2.

In addition, although the switch cover C1, C2, C3, C4 and the lens body 16 were abbreviate | omitted in FIG. 5 as mentioned above, as shown in FIG. 2, an internal mounting unit to insertion end position Z2 is shown. In the state in which the slide 4 is moved, each switch cover C1, C2, C3, C4 and each switch 51, 52, 53, 54 corresponding to each switch cover C1, C2, C3, C4 Are brought into light contact with each other, and the light emitting body 55 and the lens body 16 provided on the window 15 of the case 1 coincide along the radial direction of the case 1. In addition, the distal end of the mouse switch 54 is in a state accommodated in the internal space of the mouse switch cover C4. And in this installation state, the antenna A is exposed in the state which protruded from the front end of the case 1, and the said tip side cap member 2 is attached to the front end side of the case 1. As shown in FIG. Specifically, the tip side cap member 2 is press-fitted into the inner circumferential surface portion of the case 1. In this installation state, the antenna A is covered by the tip side cap member 2. Subsequently, the battery B (two single-cell batteries in this embodiment) is inserted from the proximal end of the case 1, and finally the male screw formed on the terminal member 32 of the proximal end cap member 3 is inserted. By screwing into the base end of the case 1, the base end side cap member 3 is attached to the base end of the case 1. As a result, the battery B comes into contact with the terminal member 32 and the spring member 9 for the battery terminal, respectively.

The laser pointer P, which is assembled in the above-described order, is provided with its pressing force with respect to the laser switch 51 by the user pressing down the laser switch cover C1, and the lens portion 72 of the wavelength conversion module 7 is provided. An arbitrary position can be irradiated and pointed by the green laser which irradiated through and passed through the through-hole 22 formed in the front-end | tip part of the front-end cap member 2. During the emission of the green laser, the light emitter 55 is turned on, and the lighting state can be visually confirmed by the window portion 15 and the lens body 16 of the case 1. Further, when the user pushes down the page back switch cover C2, the page next switch cover C3, or the mouse switch cover C4, the pressing force is applied to the corresponding switches 52, 53, and 54. The signals corresponding to the switches 52, 53, and 54 may be transmitted toward the receiver using radio waves. In this case, since the metal case 1 appropriately blocks unwanted radiation (radio noise) of the first substrate 5, interference of radio waves due to unnecessary radiation can be effectively prevented. In addition, since the periphery of the antenna A is covered by the front end side cap member 2 made of synthetic resin (non-metallic), the radio waves radiated from the antenna A are not unnecessarily attenuated. Therefore, the communication distance with an electronic device can fully be ensured.

As mentioned above, the laser pointer P which concerns on this embodiment is an operation part which indirectly receives the pushing force from the outer side of the case 1 which a user gives, through each switch cover C1, C2, C3, C4. A laser switch 51, a page back switch 52, a page next switch 53, and a mouse switch 54 are provided on the first substrate 5, and both sides of the first substrate 5 along the long axis direction. The pair of supporting grooves 18 and 18 are supported by the pair of supporting grooves 18 and 18 formed in the case 1 so as to support the pair of supporting grooves 18 and 18 in the first substrate 5. It serves as a regulating means (Z) for regulating the movement in the thickness direction.

With such a configuration, when the pressing force is applied to each of the switches 51, 52, 53, and 54, the first substrate 5 moves in the thickness direction by the pressing force, in other words, the first The substrate 5 can be preferably regulated to rotate in the radial direction of the case 1 to be out of position. That is, since the movement in the thickness direction of both side edges 5a and 5a of the first substrate 5 is regulated by the regulating means Z, for example, the electronic circuit mounted on the first substrate 5 reduces the pressing force. It can effectively prevent being moved by. In addition, like the laser pointer P1 shown in FIG. 8 mentioned above, since a special member like resin part J for fixing the board | substrate 500 is not needed inside the case 100, a laser pointer ( The number of parts constituting P) is effectively reduced.

Moreover, since the regulating means Z is provided from the insertion start position Z1 into which the 1st board | substrate 5 is inserted from the insertion end position Z2, the restriction means Z is installed in the case 1 in the internal installation unit. (4) That is, the function as a guide guide at the time of mounting the 1st board | substrate 5 is also the same, and by such a structure, the assembly process of the laser pointer P is simplified compared with the conventional laser pointer P1. It is done.

And since the restricting means Z is comprised so that a movement to the thickness direction of the 1st board | substrate 5 is impossible, the positioning of the 1st board | substrate 5 can be reliably performed.

In addition, since the regulating means Z is comprised by the pair of support grooves 18 and 18 formed by changing the thickness of the case 1, the 1st board | substrate 5 is moved to a desired position by simple processing. The position can be determined. In detail, the case 1 is made into a cylindrical shape, and the pair of supporting grooves 18 and 18 which are the restricting means Z are set in a predetermined position while setting the shape of the case 1 to a high strength.

In addition, in this embodiment, unlike the laser pointer P1 which concerns on FIG. 8, the use of the resin part J is avoided, and the space below the 1st board | substrate 5 is effectively made especially as shown in FIG. The space which creates and accommodates the 2nd board | substrate 6 is effectively ensured. That is, it is comprised so that the space inside the case 1 can be utilized effectively. That is, by adopting the regulating means Z according to the present embodiment, the laser pointer P is incorporated by employing a substrate having a multiple structure of the first substrate 5 and the second substrate 6 and incorporating many electronic components. Various functions can be provided to the system. In other words, by effectively utilizing the space inside the case 1, it is possible to store it in the smaller case 1 and to miniaturize the laser pointer P. FIG.

And the restricting means Z which concerns on this embodiment reduces the thickness of the case 1 like the support groove 18 formed in the case 1, and can move the 1st board | substrate 5 which is a board | substrate in the thickness direction. It is not limited to the groove | channel formed impossible, It is good also as a form as shown to FIG. 6 and FIG. In addition, in the said figure, description of components other than the case 1 and the board | substrate 50 is abbreviate | omitted and shown typically.

Specifically, first, as shown in FIG. 6A, two protrusions 1t and 1t are formed on the inner surface of the case 1, and grooves 1s are formed between the protrusions 1t to form the substrate 50. ) May be inserted. In addition, the board | substrate 5 is not limited to the thing of two layers like the said embodiment, It may be made only one layer like the board | substrate 50 shown in the said figure. And when the protrusion 1t is employ | adopted as the said figure (a), the restricting means Z is not limited to being formed continuously, but is formed intermittently as shown to FIG. 6 (b). You may also The substrate 50 is not limited to the one in which the substrate 50 is not movable in the vertical direction. The substrate 50 is formed like the groove 1s shown in FIG. 6C and the projection 1t shown in FIG. 6D. What is necessary is just to be able to restrict | move the movement to the thickness direction of the board | substrate 50 by operation of an operation part, even if it incorporates another component etc., even if it is formed so that it cannot move to some extent in this up-down direction. With such a configuration, it is possible to appropriately set the position of the groove 1s and set the substrate at a desired position.

In addition, as shown in FIG. 7, the restricting means Z may be a pair of opposing elevations 1u and 1u formed on the inner surface of the case 1.

Specifically, as shown in Fig. 7 (a), a case 1 having a polygonal shape, that is, a hexagonal shape, is adopted as seen in the cross section, and the substrate 50 is disposed between the opposing mouth 1u and the mouth 1u. ) May be inserted. In addition, as shown in Fig. 7 (b), the substrate 50 is supported by using the case 1 having a partial circumferential shape in cross section and using a pair of facing angles 1u and 1u. It may be. Further, as shown in Fig. 7 (c), as the case 1 having a circular outer surface, if a pair of standing angles 1u and 1u are formed facing the inner surface by varying the thickness, the opposing faces By supporting the substrate 50 between a pair of standing angles 1u and 1u, it is possible to set the regulating means Z according to the present invention. In this way, by using the elevation 1u formed on the inner surface of the case 1, it is possible to effectively avoid performing special processing for installing the restricting means Z.

As mentioned above, although embodiment of this invention was described, the specific structure of each part is not limited only to embodiment mentioned above. For example, the one side side edge part of a board | substrate may be provided with the control means which supports by the groove and the other side is supported by the corner.

In addition, various modifications are possible in the range which does not deviate from the meaning of this invention.

According to the present invention, since it is not necessary to provide a special member for fixing the substrate inside the case, the number of parts constituting the laser pointer can be effectively reduced. In other words, it is possible to reduce both the assembly cost and the assembly cost by reducing the component cost and assembly process of the laser pointer by reducing the number of parts.

And even if it does not support a board | substrate using special members, such as a resin part, since the movement of the both sides of a board | substrate to the thickness direction is regulated by a control means, the possibility that the electronic circuit mounted in a board | substrate, for example, will move is effective. Can be excluded.
