Description

Laser indicator

The present invention relates to a laser pointer that illuminates an arbitrary position by laser light.

Various laser indexers have been developed in the past, and are used at the time of presentation or conference, and are illuminated by laser light, for example, by a projector or an (OHP) overhead projector. As such a laser indexer, although it has been frequently used to illuminate a red laser, the most recent type of attention is that the relative visual sensitivity is higher than that of a red laser, even for a person who does not easily recognize the color. An easily identifiable type of illuminated green laser.

In addition, it has also developed a laser indexer that not only illuminates laser light but also communicates with infrared rays in accordance with a predetermined operation of the user, and can change the display screen and can be remotely operated, thereby making the laser indexer more Multi-functional. (For example, refer to Non-Patent Document 1)

[Non-Patent Document 1] "KOKUYO Office Supplies Album 2005", KOKUYOS & T Co., Ltd., etc., issued in December 2004, various laser indicators displayed in the upper and middle sections of p.246

The laser indexing device is usually provided with a single substrate in which the circuit is mounted inside the casing, and in order to realize the above multifunction, the circuit for illuminating the laser must be used and used for reservation. The circuit of the electronic device communication is mounted on a single substrate, and as a result, in order to secure an effective mountable area, the size of the substrate itself must be increased. On the other hand, from the viewpoints of portability, operability, etc., it is desirable that the casing has a vertically long pen-type structure, and in order to cope with such a demand, it is necessary to set the long side dimension of the substrate to be large. The substrate is mounted to implement a multi-functional circuit. However, if the length of the long side of the substrate is increased, it is of course necessary to set the long side dimension of the casing itself to be large, and as a result, there is a possibility that the size of the laser pointer itself cannot be reduced.

If the circuit for transmitting light and the circuit for communication are mounted on a single substrate, even if only one of the circuits is changed to a standard, the substrate must be changed to a circuit with other specifications. Other substrates have the disadvantage that the specifications cannot be easily changed. Even if only one of the circuits fails, the substrate on which the other circuit is mounted must be made into another substrate. Such a method of mounting a circuit for performing various functions on a single substrate is not appropriate from the viewpoint of facilitating the product and facilitating repair.

The present invention has been made in view of such a problem, and it is necessary to provide a laser indexer whose main purpose is to achieve miniaturization and to flexibly respond to changes in specifications.

The laser pointer of the present invention is a laser pointer that is irradiated with an arbitrary position by laser light, and includes a housing that is formed into a pen shape, and a housing that is installed inside the housing and that is equipped with a circuit. a plurality of substrates; and the plurality of substrates are formed in a stacked shape.

The "pen type" as used herein refers to a vertically elongated structure including a shape of a slightly cylindrical shape or a slightly polygonal cylinder, or a shape in which a concave portion or a curved portion is formed along a part of the longitudinal direction, and the like. The concept of various shapes that can be held.

According to this configuration, since the circuits necessary for realizing the multi-function can be separately mounted on a plurality of substrates, compared with the manner in which all the circuits are mounted on a single substrate, the circuit of one substrate is compared. The mounting area becomes smaller, and the long side size of each substrate can be set smaller. As a result, the long side size of the casing can also be set small, and the laser indexer can be miniaturized. In the case where the circuit is classified into, for example, the state of each circuit that exhibits a specific function, and the circuit is mounted on each of the substrates, when the specifications are changed, the substrate on which the circuit to be changed is mounted is replaced, and the circuit is replaced. Other substrates can be used in accordance with circuits of other specifications, and the specifications can be easily changed. When a circuit for one of the functions is malfunctioning, it is only necessary to replace the substrate on which the circuit of the one function is mounted, and the replacement work can be smoothly performed, and the cost required for the replacement work can be suppressed.

By forming a plurality of substrates in a stacked shape, and by setting the long side dimension of each substrate to be small, the deformation of each substrate can be suppressed, and among the substrates, one of the substrates can also be used as a structural member. Function. By using one of the substrates not only as a function of the substrate, but also actively using it as a structural member, it is not necessary to additionally use other dedicated members which are only functions of the structural member, and the configuration can be simplified and the number of parts can be reduced.

By mounting the switch directly or indirectly pressed by the user during operation on one of the above substrates, it is possible to easily prevent the substrate from being generated when the downward pressure acts on the switch mounted on the substrate. Flexural deformation.

When the user presses the switch, in order to prevent the operation force from causing the substrate to be flexed and deformed and the relative displacement with respect to the housing, in order to prevent the occurrence of an erroneous action, the housing is provided to limit the one substrate. The movement restriction means for moving in the thickness direction may be used.

In a specific embodiment, the casing is formed in a substantially cylindrical shape, and the movement restricting means is a pair of grooves formed along the longitudinal direction of the inner circumference of the casing.

When a circuit for emitting laser light and a circuit for communicating with a predetermined electronic device are mounted on different substrates, the specifications can be easily changed by appropriately changing the circuits of the respective substrates. It can flexibly respond to small quantities of various types of production.

According to the present invention as described above, the necessary circuits for exerting various functions are appropriately mounted separately on a plurality of substrates, so that compared with a method of mounting all circuits on a single substrate, one substrate is used. The mounting area of the circuit becomes smaller, and the long side size of each substrate can be set smaller. Thereby, the long side size of the casing can be set small, and the laser indexer can be miniaturized.

The terminal member 32 is formed with a male screw portion 32a that can be screwed to the female screw portion 17 formed on the inner circumferential surface of the base end portion of the casing 1.

The internal mounting unit 4, as shown in Fig. 5, is mainly provided integrally with a first substrate 5 on which a circuit for communicating with a predetermined electronic device (not shown) is mounted, and is used to make red A second substrate 6 of a light-emitting laser (hereinafter referred to as "laser" for short) is used, and a wavelength conversion module 7 for converting a red laser into a green laser.

A circuit for communicating with the electronic device is mounted on the first substrate. Specifically, in the first substrate 5, the components of the return page number switch 52, the next page number switch 53, and the mouse switch 54 are sequentially mounted from the base end side, and the respective switches 52, When the downward pressure is applied to 53 and 54, the predetermined signal corresponding to each of the switches 52, 53, 54 will be switched, that is, the screen displayed on the display screen not shown will be switched to the return of the previous screen. a screen signal, a screen feed 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, using Electromagnetic waves are sent to the receiver connected to the above electronic device or built-in.

The second substrate 6 has a width dimension and a long side dimension which are set smaller than the first substrate, and a circuit for causing the red laser to emit light is mounted on the second substrate 6. Whether or not the laser light is controlled is performed by applying a downward pressure to the laser switch 51 mounted on the first substrate 5. On the first substrate 5, an illuminator 55 that is turned on in conjunction with the light emission of the laser light is mounted. In the present embodiment, the illuminator 55 is mounted on the front end side of the mounting portion of the mouse switch 54.

The first substrate 5 and the second substrate 6 having such a configuration are stacked in a state in which the central axes along the respective longitudinal directions are aligned, and are stacked in a predetermined distance in the thickness direction. The first substrate 5 and the second substrate 6 are connected to each other via a connection member R provided on the proximal end side and the distal end side, and are connected to each other on the first substrate 5 by the connection member R. The mounted circuit and the circuit mounted on the second substrate 6 are electrically connected to each other.

At the base end portion of the first substrate 5, a partition member 8 made of, for example, a synthetic resin material, and a spring member 9 serving as a terminal of the battery B are integrally attached by appropriate mounting means.

The wavelength conversion module 7 is provided at the front end portion of the first substrate 5, and inside the module main body 71, a 808 nm red laser that emits light, for example, a semiconductor laser light-emitting element (not shown) is converted into 1064 nm. When the laser beam is crystallized by wavelength conversion (not shown), a green laser beam converted to a wavelength of 532 nm is irradiated, and the green laser beam is irradiated through the lens unit 72. In order to efficiently radiate heat generated when a 1064 nm laser is converted into a 532 nm green laser, the output of the green laser is stabilized, and the module main body 71 is made of brass.

Antenna A of part A1. The antenna A is electrically connected to a circuit (see FIG. 3) mounted on the first substrate 5 by a substantially linear portion A2 provided on one end side thereof, and the coil portion A1 is used. Therefore, the light-emitting path of the green laser beam irradiated from the irradiation unit can be ensured, and the distance between the laser pointer P and the electronic device connected to or including the above-mentioned receiver can be effectively ensured.

Next, the assembly procedure of the laser pointer P composed of each component will be described.

First, the laser switch hole 11, the return page number switch hole 12, the next page number switch hole 13, and the mouse switch hole 14 formed in the casing 1 are respectively attached: a laser switch case C1. Returns the page number switch housing C2, the next page number switch housing C3, and the mouse switch housing C4. Each of the switch housings C1, C2, C3, and C4 integrally includes a stopper portion C11, C21, C31, and C41 that can abut against the inner peripheral surface of the casing 1, by the inner peripheral surface of the casing 1. The switch housings C1, C2, C3, and C4 are attached to the side, and the stopper portions C11, C21, C31, and C41 are brought into contact with the inner peripheral surface of the casing 1 to prevent the respective switch housings C1, C2, C3, and C4 from coming off. It goes out to the outside of the casing 1. In the present embodiment, in order to easily recognize the return page number switch case C2 and the next page number switch case C3 having similar shapes, the protrusion C32 is provided at the upper end portion of the next page number switch case C3. Next, the inner mounting unit 4 is inserted from the front end side of the casing 1. At this time, each of the switches 52, 53, 54 which are mounted on the first substrate 5, and the respective hole portions formed in the casing 1 (the laser switch hole 11, the return page number switch hole 12, the second) The page number switch hole 13 and the mouse switch hole 14) are oriented in the same direction, and the internal mounting unit 4 is inserted into the casing 1 from the spring member 9 for the battery terminal, and both sides of the first substrate 5 are placed. The end portion is fitted to the support groove 18 provided in the inner peripheral surface of the casing 1 while guiding the side edge portion along the longitudinal direction of the first substrate 5 along the support groove 18 The inner mounting unit 4 is slid toward the longitudinal direction of the casing 1. The pair of support grooves 18 serve as guides for guiding the mounting position of the first substrate 5 with respect to the casing 1, and further guiding the mounting position of the inner mounting unit 4. When the inner mounting unit 4 is slid to a point where the front end portion of the casing 1 slightly coincides with the starting portion of the coil portion A1 of the antenna A, the respective switch housings C1, C2, C3, C4, and these switches The switches 51, 52, 53, 54 corresponding to the casings C1, C2, C3, and C4 are in a state of slight contact with each other, and the illuminator 55 and the lens body 16 provided in the window portion 15 of the casing 1 are along the basket. The body 1 has the same diameter direction. The front end portion of the mouse switch 54 is in a state of being housed in the internal space of the mouse switch case C4. In this mounted state, the antenna A is exposed from the front end of the casing 1, and the front end side cover member 2 is attached to the front end side of the casing 1. Specifically, it is performed by pressing the front end cover member 2 into the inner peripheral surface of the casing 1. In this mounted state, the coil portion A1 of the antenna A is covered by the front end side cover member 2. Next, the battery B is inserted from the proximal end side of the casing 1 (two fourth batteries in the present embodiment), and finally the male screw portion formed by the terminal member 32 of the proximal end side cover member 3 is screwed to the basket. The female screw portion 17 formed at the proximal end portion of the body 1 is attached to the proximal end portion of the casing 1 with the proximal end side cover member 3. As a result, the battery B is in contact with the terminal member 32 and the spring member 9 for the battery terminal, respectively, and is in a state in which the battery can be energized.

In the laser pointer unit P assembled in the above order, the user applies the downward pressure to the laser switch 51 by pressing the laser switch housing C1, and then irradiates the lens portion 72 of the wavelength conversion module 7 with the lens portion 72, and By indicating the green laser beam passing through the through hole 22 formed at the front end portion of the front end side cover member 2, it is possible to illuminate an arbitrary position. During the illumination of the green laser, the illuminator 55 is turned on, and the lighting state can be visually confirmed by the window portion 15 of the casing 1 and the lens body 16. The user returns to the page number switch housing C2, the next page number switch housing C3, and the mouse switch housing C4 by pressing, and applies the downward pressure to the corresponding switches 52, 53, 54 to use the electric waves. The respective signals corresponding to the switches 52, 53, 54 are sent to an electronic device connected or built into the receiver. In this case, the metal casing 1 appropriately shields unnecessary radiation (electric wave noise) of the circuit mounted on the first substrate 5, and can effectively prevent interference of radio waves caused by the unnecessary radiation. . In addition, since the periphery of the coil-shaped portion A1 of the antenna A is covered by the distal end side cover member 2 made of synthetic resin (non-metallic), the radio wave radiated from the antenna A is not attenuated. Thus, the communication distance with the electronic device can be sufficiently ensured. The first substrate 5 is mounted: each of the switches 51, 52, 53, 54 that indirectly receives the downward pressure applied by the user via the respective switch housings C1, C2, C3, and C4, by being along the first The side edge portions on both sides in the longitudinal direction of the substrate 5 are supported by the support grooves 18 of the casing 1. Therefore, when the downward pressure is applied to the switches 51, 52, 53, and 54, the downward pressure can be restricted. The first substrate 5 is moved toward the thickness direction, and the positional displacement of the first substrate 5 with respect to the casing 1 is prevented, and the occurrence of a malfunction can be suppressed. The pair of support grooves 18 provided in the casing 1 function as a movement restricting means for restricting the movement of the first substrate 5 in the thickness direction.

In the laser pointer P of the present embodiment, the first substrate 5 and the second substrate 6 are formed in a two-layer structure along the diameter direction of the housing 1 of the pen type, so that all the circuits are mounted in a single unit. The mounting area of the circuits of the substrates 5 and 6 is made smaller than that of the substrate, and the long side dimensions of the substrates 5 and 6 can be set small. As a result, the length of the long side of the casing 1 can be set small, and the size of the laser pointer P can be easily reduced, and the portability, the accommodation property, and the operability are excellent.

Since the long side dimension of each of the substrates 5 and 6 can be set small, even when the switches 52, 53, 54 which indirectly apply the downward pressure are mounted on the first substrate 5 when the user operates, The deflection deformation of the first substrate 5 caused by the downward pressure is suppressed. The first substrate 5 functions not only as a printed circuit board but also as a support member for supporting the switches 51, 52, 53, 54 and having strength that is not deformed by the downward pressure, and is therefore provided separately. Compared with the manner of supporting the members, the number of parts can be effectively reduced and the structure can be simplified. In addition, the first substrate 5 functions as a connecting member for connecting the spring member 9 for the battery terminal and the wavelength conversion module 7, whereby the inside of the casing 1 can be mounted. Each of the members is assembled into the inner mounting unit 4, so that the assembly work can be simplified, and the convenience of the process of attaching to the front stage of the casing 1 can be facilitated. On the other hand, the first substrate 5 can be actively utilized as a supporting member and a structural member as a function of the connecting member, and the number of parts can be effectively reduced.

Since the housing 1 is provided with a pair of support grooves 18 for restricting the movement of the first substrate 5 toward the thickness direction as a movement restricting means, when the user presses the switches 51, 52, 53, At the time of 540, it is possible to prevent the first substrate 5 from being flexibly deformed in the thickness direction and being displaced from the position of the casing 1 by the simple operation, and it is possible to ensure reliable operability.

In addition, a circuit for causing laser light emission is mounted on the first substrate 5, and a circuit for communicating with a predetermined receiver is mounted on the second substrate 6, so when the specifications are changed, The first substrate 5 or the second substrate 6 of the circuit to be changed is mounted, and other substrates corresponding to circuits of other specifications can be replaced, and the product can be easily developed, and various types can be flexibly adapted. Small production. When a circuit relating to one of the functions causes a failure, it is only necessary to replace either one of the first substrate 5 or the second substrate 6 in which the circuit for the one function is mounted, and the manner in which the two substrates 5 and 6 have to be replaced. In comparison with the smooth repair (replacement) operation, the cost required for repair (replacement) can be suppressed.

The present invention is not limited to the embodiments described in detail above.

For example, in the above embodiment, a two-layer structure is formed by two substrates, and the present invention is not limited thereto, and a method of stacking three or more substrates may be employed.

The housing may be a long pen-shaped structure that can be gripped by a user, and may be a polygonal tube shape in addition to the cylindrical shape, or may have a concave portion or a protrusion formed in a portion along the longitudinal direction. The shape of the bend.

In the above-described embodiment, each of the switches indirectly receives the operating force (downforce) of the user via the outer casing, and may be a type that directly receives the operating force (downforce) of the user without providing the outer casing. In this case, since the outer casing is not required, the number of parts can be reduced. In addition to the above-described switches, various switches such as switches that function to correspond to the left and right buttons of the mouse can be mounted on the first substrate.

As the movement restricting means, in addition to the above-described support groove, it is also possible to protrude from the inner circumference of the casing in the radial direction and to support the projecting portion of the side edge portion of the substrate. In this case, the protrusion may be provided at a position where the substrate may be sandwiched in the thickness direction, or the protrusion may be provided only at a position on the back surface of the support substrate. Even in the latter manner, when the switch is depressed, it can be appropriately prevented because the downward pressure causes the substrate to move toward the thickness direction thereof. Further, it is preferable that the support grooves and the projections are continuously provided along the longitudinal direction of the casing, and may be intermittently provided along the longitudinal direction of the casing. Further, if the casing is in the shape of a polygonal cylinder such as a rectangular tube shape, the both side edges of the substrate may be supported by the opposite corner portions or the arbitrarily selected corner portions, and the corner portion may be used as a movement restricting means. Function.

The circuit on which the first substrate is mounted for illuminating the laser light may be mounted on the second substrate for communication with a predetermined electronic device. In addition to the RF method, a communication method using electromagnetic waves other than the 2.45 GHz band, such as infrared rays, may be used as the communication method.

It is also possible to use a laser pointer that illuminates a red laser without a green laser.
