Thereby, an occupation area of a battery pack 5 inside the laser marking device 1 is restricted from increasing in size, and a degree of freedom of arrangement for each component inside the laser marking device 1 is restricted from decreasing. Further, the laser marking device 1 having a constitution in which the pack mounting part 7 can fit a battery pack 5 that is capable of being charged and discharged, reduces waste of resources compared to when a primary battery (such as a dry battery) is used, since the battery pack 5 can be repeatedly used by being charged.SELECTED DRAWING: Figure 2

Description

  The present invention relates to a laser marking device that is used in civil engineering, construction work, and the like and projects a reference line by laser light onto an object.

  As a laser marking device used for civil engineering and construction work, one using a dry cell as a power source is known. This laser marking device generates laser light by supplying electric power from a dry battery, and projects a reference line by the laser light onto an object.

  When a dry battery is used as a power source, the dry battery is a primary battery and cannot be charged. Therefore, when the dry battery is discharged with the use of the laser marking device, it is necessary to replace it with a new dry battery. When such replacement is repeated, the number of dry batteries to be discarded increases, and there is a risk that waste of resources may be promoted.

  On the other hand, a laser marking device using a battery pack as a rechargeable secondary battery instead of a dry battery has been proposed (Patent Document 1). Such a chargeable / dischargeable battery pack can be reused by charging even when it is discharged due to the use of the laser marking device and power supply becomes impossible. In other words, by using a chargeable / dischargeable battery pack as a power source, it is possible to reuse by charging, so that waste of resources can be reduced compared to the case of using a primary battery (dry battery).

  The laser marking device described in Patent Document 1 is a method for attaching and detaching a battery pack by moving the battery pack in a direction perpendicular to the outer surface of the laser marking device (hereinafter also referred to as an insertion method). Is adopted.

US Pat. No. 6,915,583

  However, when the “plug-in method” is adopted as the battery pack attachment / detachment method, the area occupied by the battery pack inside the laser marking device becomes large, and the arrangement area of each component (laser light generation unit, etc.) housed inside Becomes relatively small. For this reason, there exists a problem that the freedom degree of arrangement | positioning of each component within a laser marking device falls.

  Therefore, an object of the present invention is to provide a laser marking device in which waste of resources is reduced and the degree of freedom of arrangement in each component housed therein is difficult to be lowered.

  A laser marking device according to one aspect of the present invention is a laser marking device that projects a reference line by a laser beam onto an object, and includes a laser beam generation unit, a housing, and a pack mounting unit. ing.

  The laser light generation unit generates laser light. The housing is formed in a columnar shape extending in the axial direction with the central axis extending in the vertical direction as a center, and houses a laser light generation unit inside and a laser light passage unit that allows laser light to pass from the inside toward the outside. Prepare.

The pack mounting unit is configured to mount a battery pack that is a battery pack for supplying power to the laser light generation unit and that can be charged and discharged.
The pack mounting portion is formed on the side surface of the housing and includes a slide rail formed in parallel to the side surface. The pack mounting portion is configured to attach and detach the battery pack by sliding the battery pack along the slide rail.

  As described above, the method of attaching / detaching the battery pack by sliding the battery pack parallel to the side surface of the housing is compared with the method of attaching / detaching the battery pack by moving the battery pack in the direction perpendicular to the outer surface of the housing (insertion method). Thus, the battery pack can be arranged in a region away from the center position of the housing.

  Thereby, the influence of the arrangement region of the battery pack on the arrangement region of the laser light generation unit in the inner region of the housing can be reduced. In other words, it is possible to suppress an increase in the area occupied by the battery pack inside the laser marking device, and to suppress a reduction in the degree of freedom of arrangement of each component inside the laser marking device.

  And since this laser marking device has a configuration in which the pack mounting part can be mounted with a chargeable / dischargeable battery pack, since the battery pack can be used repeatedly by charging, compared to the case of using a primary battery (dry cell or the like). , Resource waste can be reduced.

Therefore, according to this laser marking device, it is possible to provide a laser marking device in which waste of resources is reduced and the degree of freedom of arrangement in each component housed in the inside is difficult to decrease.
In addition, when the laser marking device having such a configuration is realized by changing the design based on the existing laser marking device, the arrangement area of each component (laser light generation unit, etc.) accommodated therein is arranged. The battery pack can be attached without significantly changing the battery pack.

  Next, in the above-described laser marking device, the battery pack may have a shape in which the maximum vertical dimension is smaller than the maximum horizontal dimension when mounted on the pack mounting portion.

  The battery pack having such a shape has a smaller vertical dimension (height dimension) when mounted on the pack mounting portion than a battery pack having a maximum vertical dimension larger than the horizontal maximum dimension. Can do.

Thereby, it can suppress that a vertical direction dimension (height dimension) becomes large as the whole laser marking device, and the risk of the fall accompanying the increase in a height dimension can be reduced.
Next, in the laser marking device described above, the pack mounting portion may have a slide rail formed parallel to the horizontal direction.

  By providing such a slide rail, the movement direction of the battery pack when the battery pack is attached / detached is a horizontal direction, and the movement in the vertical direction is eliminated. In this case, when the battery pack is attached / detached, it is possible to suppress the upper region and the lower region of the outer surface of the housing from interfering with the battery pack, and it is possible to suppress the occurrence of damage due to the interference.

  In particular, in the configuration in which the laser beam passage portion is arranged in the upper region or the lower region of the pack mounting portion, the laser beam passage portion can be prevented from being damaged, and therefore the laser beam can be appropriately projected onto the object.

  When the battery pack is mounted on the pack mounting portion, the maximum vertical dimension is smaller than the maximum horizontal dimension, and the slide rail is formed in parallel to the horizontal direction in the pack mounting portion. It is good also as the structure of having. By adopting such a configuration, the distance between the slide rails can be reduced, and an increase in the height of the laser marking device can be suppressed.

Next, in the laser marking device described above, the housing may include a base portion and a rotating portion, and the pack mounting portion may be formed on a side surface of the rotating portion.
The base part comes into contact with the installation place of the laser marking device. The rotating unit accommodates the laser beam generating unit therein, includes a laser beam passing unit, and is fixed to the upper side of the base unit so as to be rotatable about a central axis extending in the vertical direction.

As described above, since the housing includes the base portion and the rotation portion, the projection direction of the laser light can be easily adjusted by the rotation of the rotation portion.
Further, by adopting a configuration in which the pack mounting part is formed on the side surface of the rotating part, it is not necessary to arrange the energization path from the battery pack to the laser light generating part so as to straddle both the base part and the rotating part. Thereby, it is not necessary to provide an energization path at a location where the relative position changes due to rotation, and the energization path can be prevented from becoming complicated.

Alternatively, in the above-described laser marking device, the housing may include a base portion and a rotating portion, and the pack mounting portion may be formed on the side surface of the base portion.
The base part comes into contact with the installation place of the laser marking device. The rotating unit includes a laser beam passage unit and is fixed to the upper side of the base unit so as to be rotatable about a central axis extending in the vertical direction.

As described above, since the housing includes the base portion and the rotation portion, the projection direction of the laser light can be easily adjusted by the rotation of the rotation portion.
In addition, by adopting a structure in which the pack mounting part is formed on the side surface of the base part, the installation position of the relatively heavy battery pack among the components of the laser marking device is lowered, and the center of gravity of the laser marking device is reduced. Can reduce the risk of falls.

  The laser light generation unit may be entirely accommodated in the rotation unit, or a part of the laser light generation unit may be accommodated in the rotation unit and the other may be accommodated in the base unit. There may be.

  Next, in the laser marking device having a configuration in which the pack mounting portion is formed on the side surface of the base portion, the housing includes a signal receiving unit that receives a command signal by radio from the outside, A configuration may be adopted in which the lowermost part of itself is higher than the uppermost part of the signal receiving unit.

Thereby, it can suppress that the command signal by the radio | wireless from the outside is interrupted | blocked by a battery pack, and a command signal can be received appropriately in a signal receiving part.
The command signal includes, for example, a command signal including command information regarding the laser light emission state (laser brightness, emission direction, etc.). Examples of the wireless command signal include a signal used for infrared communication and a signal used for BlueTooth (registered trademark) communication.

Next, in the above-described laser marking device, the laser beam generating unit includes a laser beam emitting unit and an emission control unit, and the laser marking unit is arranged in a virtual plane parallel to the slide rail and including the central axis. A configuration in which at least a part of the injection control unit is arranged in the second area when the dispenser is divided into a first area including the pack mounting part and a second area not including the pack mounting part. It may be.

The laser light emitting unit emits laser light. The emission control unit controls the emission state of the laser beam at the laser beam emitting unit.
Further, since the first region is provided with the pack mounting portion, the battery pack is arranged. The battery pack is a relatively heavy component among the components of the laser marking device, and is disposed in the first region.

  In this way, by arranging at least a part of the injection control unit in a region different from the pack mounting unit (battery pack) in the two regions (first region and second region) divided by the virtual plane, The center of gravity of the laser marking device can be brought closer to the central axis as compared with the case where the entire pack mounting part (battery pack) and the injection control part are arranged in the same region.

Thereby, it can suppress that the gravity center in a laser marking device deviates to the battery pack side, and can suppress the risk of a fall.
In addition, the injection | emission control part can take the form with which not only the form with which it is provided as one member but is distributed and provided with a some member. When the injection control unit is provided as one member, the injection control unit is arranged in a state straddling the first region and the second region, so that at least a part of the injection control unit is the second. It can be in a state of being arranged in a region. Further, in the case where the injection control unit is distributed and provided in a plurality of members, at least one of the plurality of members is arranged in the second region, so that at least one of the injection control units is arranged. The part can be in a state of being arranged in the second region.

  Furthermore, the above-described laser marking device may be configured such that the entire ejection control unit is arranged in the second region instead of a part of the ejection control unit. With this configuration, even when a heavier battery pack is used, the center of gravity of the laser marking device can be prevented from being biased toward the battery pack, and the risk of falling can be suppressed.

Next, the above-described laser marking device may include an external power supply connection unit that is connected to an external power supply that supplies power to the laser light generation unit.
By providing such an external power supply connection unit, the laser marking device can receive power from an external power supply different from the battery pack. As a result, the laser marking device can emit laser light by supplying power from an external power source even when the state of the battery pack is “the remaining charge amount is zero” or “the failure state”. .

  Next, in a laser marking device including an external power supply connection unit, the external power supply connection unit is configured to be connected as an external power supply to an external power supply whose output voltage is in the range of 4.5 to 5.5V. May be.

  External power supplies configured so that the output voltage falls within the above range are widely distributed as general-purpose products, and such external power supplies are easily available. Thereby, even when the state of the battery pack becomes “the remaining charge amount is zero” or “the failure state”, the laser light can be emitted by the power supply from the external power source.

  Next, the laser marking device including the external power supply connection unit described above includes a pack voltage conversion unit that converts a voltage received from the battery pack into a voltage value suitable for the laser light generation unit, and an external power supply unit from the external power supply. An external voltage conversion unit that converts the received voltage into a voltage value suitable for the laser light generation unit.

  By thus performing voltage conversion by including the pack voltage conversion unit and the external voltage conversion unit, laser irradiation can be realized using power from various battery packs and various external power sources.

Next, in the above-described laser marking device, the laser light generation unit may generate green laser light as the laser light.
The laser light generator that generates a green laser consumes more power than the laser light generator (laser element) that generates red laser light, which has been widely used in the past. Will cause the power to discharge.

For this reason, wasteful use of resources can be further suppressed by using a chargeable / dischargeable battery pack as a power source, compared to the case of using a primary battery (dry battery).
By the way, the battery pack becomes heavier as the rated capacity increases. In the above-described laser marking device, as the weight of the battery pack attached to the pack attachment portion increases, the center of gravity is biased toward the battery pack, and there is a possibility of falling depending on the situation (tilt or the like) of the installation location.

  Therefore, the above-described laser marking device may include a leg portion and an auxiliary support portion. The leg portion is provided at the bottom of the housing so as to abut the installation place of the laser marking device. The auxiliary support part is extended from the housing.

  The auxiliary support portion includes a grounding portion at the tip of the auxiliary support portion when viewed from above the central axis of the housing, and a virtual line segment connecting at least a part of the grounding portion and the central axis is the pack mounting portion. The grounding portion is arranged so as to intersect.

The grounding portion of the auxiliary support portion is disposed in a region lower than the pack mounting portion, and is disposed via a gap with respect to the virtual ground contacting the leg portion.
Even if the center of gravity of the laser marking device equipped with such an auxiliary support portion is biased toward the battery pack due to the weight of the battery pack attached to the pack attachment portion, the auxiliary support portion is brought to the ground before it completely falls. It can abut and support the laser marking device.

Therefore, according to this laser marking device, by providing the auxiliary support portion, it is possible to suppress the overturn even when a heavy battery pack is attached.
The “virtual ground contacting the leg” is a virtual ground obtained by extending the ground contacted by the leg when the laser marking device is installed at the installation location. Further, a plurality of leg portions may be provided and each may be configured to be extendable / contractible. In this case, the virtual ground may be determined based on the ground on which the leg set in the shortest state comes into contact.

Next, in the laser marking device including the leg portion and the auxiliary support portion, the auxiliary support portion may be provided in a region below the pack mounting portion.
The auxiliary support portion having such a configuration has its own length dimension (in other words, from the grounding portion to the housing, compared to a configuration in which at least a part of the auxiliary support portion is also disposed in the region above the pack mounting portion. The dimension to the connection end can be shortened. For this reason, while being able to reduce the material cost of an auxiliary | assistant support part, the raise of the manufacturing cost of a laser marking device can be suppressed.

  Further, since the auxiliary support portion having such a configuration is not disposed in the region having the same height as the pack mounting portion or in the region above the pack mounting portion, there is no interference with the battery pack when the battery pack is attached or detached. It is difficult to produce.

Next, in the laser marking device including the leg portion and the auxiliary support portion, the auxiliary support portion may be attached to the housing in a form that can be moved by rotation or sliding. And the auxiliary support part is fixed at a predetermined support position within its movable range, so that the grounding part is arranged so that the virtual line segment intersects the pack mounting part, and the grounding part is The structure arrange | positioned through a clearance gap with respect to virtual ground in the area | region lower than a pack mounting part may be sufficient.

  By providing the auxiliary support portion having such a configuration, it is possible to switch between the case where the auxiliary support portion is fixed at the support position and the case where the auxiliary support portion is not fixed, depending on the use state of the laser marking device. For example, when the laser marking device is used, the auxiliary support portion is fixed at the supporting position, and when the laser marking device is not used (during transportation or storage), the auxiliary supporting portion is located at a position different from the supporting position (for example, , Transport position, storage position, etc.). Alternatively, when the laser marking device is not used, the auxiliary support portion may be freely movable.

Next, in the above-described laser marking device including a movable auxiliary support portion, the auxiliary support portion may include a handle portion for the user to grasp.
Thus, since the auxiliary support portion includes the handle portion, it is not necessary to separately provide the auxiliary support portion and the handle portion, and an increase in the number of parts constituting the laser marking device can be suppressed.

  Next, in the above laser marking device including the movable auxiliary support portion, the auxiliary support portion is configured such that the grounding portion is movable to a region higher than the upper end of the housing, and the grounding portion and the handle portion. May be the same site.

As described above, since the grounding portion and the handle portion are the same portion, the auxiliary support portion can be prevented from being enlarged compared to the case where the ground support portion and the handle portion are formed in different portions in the auxiliary support portion.
Next, in the above-described laser marking device including the movable auxiliary support portion, the auxiliary support portion is attached to the side surface of the housing via the two connecting portions and can be rotated around the two connecting portions. May be configured.

  The auxiliary support portion includes two extending portions extending from each of the two connecting portions toward the grounding portion. The position of the two connecting portions in the housing in plan view from the upper side of the central axis is such that when the auxiliary support portion is fixed at the support position, the grounding portion and the two extending portions are at least mounted on the side surface of the housing. This is a position that surrounds the formation area of the part.

  Such a laser marking device has a configuration in which the auxiliary support portion is attached to the side surface of the housing via the two connecting portions, so that the laser marking device can be compared with a configuration that is attached via one connecting portion. Even when the weight increases, the auxiliary support portion can be used to lift the weight. Thereby, even if it is a heavy laser marking device, the user can grasp the handle part of an auxiliary support part, and can convey this laser marking device stably.

  Further, this laser marking device rotates the auxiliary support portion so that the grounding portion moves to a lower area than the pack mounting portion by determining the positions of the two connecting portions in the housing as described above. Thus, it is easy to arrange the grounding portion so that the predetermined condition is satisfied. The predetermined condition is that the grounding portion is disposed so that the virtual line segment intersects the pack mounting portion, and that the grounding portion is disposed at a position with a gap with respect to the virtual ground in a region lower than the pack mounting portion. It is. By arranging the grounding portion of the auxiliary support portion at such a position, the laser marking device can be prevented from falling.

Next, in the above-described laser marking device provided with the auxiliary support portion that rotates around the two connecting portions, one of the two extending portions is a soft extending portion formed of an elastically deformable soft material. The other may be a hard extending portion made of a hard material that is harder and not elastically deformed than the soft extending portion.

  The soft extension part is arranged at a position where the movement locus of the auxiliary support part when the auxiliary support part rotates overlaps the movement region when the battery pack is attached / detached, and the hard extension part moves by itself when the auxiliary support part rotates. The locus is arranged at a position where it does not overlap the movement area when the battery pack is attached / detached.

  In this laser marking device, since the soft extension portion can be elastically deformed, even if the soft extension portion and the battery pack interfere when the battery pack is attached or detached, the soft extension portion is elastically deformed. Thus, the battery pack can be attached and detached continuously.

  Next, in the above-mentioned laser marking device including a movable auxiliary support portion, the auxiliary support portion is attached to the side surface of the housing via one connection portion and is configured to be rotatable about the connection portion. May be. The auxiliary support portion includes an extending portion that extends from the connecting portion toward the grounding portion. The position of the connecting portion in the housing is a position where the moving region of the grounding portion and the extending portion when the auxiliary support portion rotates does not overlap the moving region of the battery pack during the attachment / detachment work to the pack mounting portion.

  In such a laser marking device, the auxiliary support portion is configured to be attached to the side surface of the housing via one connecting portion, so that the auxiliary support portion has a structure that is compared to a configuration that is attached via two connecting portions. The moving area of the grounding portion and the extending portion during rotation is reduced. For this reason, in determining the position of the connecting portion in the housing, the degree of freedom of the position of the connecting portion is expanded while preventing the moving region of the grounding portion and the extending portion from overlapping the moving region of the battery pack.

  Next, in the laser marking device including the movable auxiliary support portion, the auxiliary support portion is attached to the side surface of the housing via the two connecting portions and is slidable along the two connecting portions. May be configured. The grounding portion is formed at a position lower than the connecting portion in the auxiliary support portion. A handle part is formed in a position higher than a connection part among auxiliary support parts.

  By providing the above-described auxiliary support portion, the laser marking device can realize a configuration that can be easily carried by the handle portion in addition to preventing the grounding portion from falling. Since the auxiliary support part is configured to be moved by sliding and the grounding part and the handle part are provided in different parts, the auxiliary support part is moved (for example, moved from the support position to another position). Can be executed easily.

Next, in the above-described laser marking device including the coupling portion and the handle portion, the coupling portion may be formed at a position higher than the center of gravity of the laser marking device in the housing.
In this laser marking device, when the user grabs the handle and lifts the laser marking device, the center of gravity is lower than the connecting portion. The removed main body is in a stable state. For this reason, when the laser marking device is lifted by grasping the handle portion, the housing can be prevented from rotating or sliding and turning upside down, and the laser marking device can be carried in a stable state.

Next, in the above-described laser marking device including the auxiliary support portion, the grounding portion of the auxiliary support portion may be configured such that its surface is made of an elastic material.
By providing the auxiliary support portion having such a configuration, when the laser marking device is tilted and the grounding portion hits the ground, the portion of the grounding portion formed of an elastic material exhibits a non-slip function. , Laser marking device will be more difficult to fall. Further, in a configuration in which the grounding portion and the handle portion are the same part, the surface of the handle portion (in other words, the grounding portion) is formed of an elastic material so that the user can grasp the handle portion and laser It is possible to prevent the laser marking device from falling due to slipping of the handle when transporting the marking device.

  According to the laser marking device of the present invention, it is possible to provide a laser marking device in which waste of resources is reduced and the degree of freedom of arrangement in each component housed in the interior is unlikely to decrease.

  The operation switch 51 includes a pack-side switch unit 51a and an external power supply-side switch unit 51b, and is configured to be able to switch the state (ON state or OFF state) of each switch unit by a user operation.

  As shown in FIG. 7, the pack mounting part 7 (specifically, the electrode terminal 45) is connected via the operation switch 51 (specifically, the pack side switch part 51a), the pack side transformer circuit 61, and the changeover switch 65. The laser beam generator 9 is configured to be electrically connectable. The pack side transformer circuit 61 converts the output voltage (for example, 12.0V) of the battery pack 5 mounted on the pack mounting unit 7 to a voltage (for example, 7.0V) suitable for driving the laser light generating unit 9. It is a circuit for conversion (step-down).

  The external power supply connection unit 53 is configured to be electrically connectable to the laser light generation unit 9 via the operation switch 51 (specifically, the external power supply side switch unit 51b), the external power supply side transformer circuit 63, and the changeover switch 65. Has been. The external power supply side transformer circuit 63 uses the output voltage (for example, 5.0 V) of the AC adapter 71 connected to the external power supply connection unit 53 as a voltage (for example, 7.0 V) suitable for driving the laser light generation unit 9. This is a circuit for voltage conversion (step-up).

The external power supply connection unit 53 includes a connection detection unit 53a, and the connection detection unit 53a detects whether or not an external power supply (such as the AC adapter 71) is connected. The detection result in the connection detection unit 53a is used for setting the switching state of the selector switch 65. That is, when the connection detection unit 53a does not detect the connection of the external power supply, the changeover switch 65 is set to a state in which the contact a and the contact c are connected, so that the pack side transformer circuit 61 and the laser are switched. The state in which the light generation unit 9 is connected is set. Further, when the connection detection unit 53a detects the connection of the external power supply, the changeover switch 65 is set to a state in which the contact b and the contact c are connected, so that the external power supply side transformer circuit 63 and the laser are switched. The state in which the light generation unit 9 is connected is set.

  When the operation switch 51 is in the ON state and the external power source (AC adapter 71) is connected to the external power source connection unit 53, the laser light generation unit 9 is connected to the external power source (AC adapter 71). In contrast, power is supplied.

  Furthermore, when the operation switch 51 is in the OFF state, the power supply to the laser light generation unit 9 is stopped regardless of whether or not the external power supply (AC adapter 71) is connected to the external power supply connection unit 53.

[1-3. Battery pack and pack mounting part]
As shown in FIG. 3, the battery pack 5 is configured such that the vertical maximum dimension H1 is smaller than the horizontal maximum dimension W1 (H1 <W1) when mounted on the pack mounting part 7. .

  The battery pack 5 having such a shape has a pack mounting portion as compared with a battery pack having a shape (H1> W1) in which the vertical maximum dimension H1 when mounted on the pack mounting section 7 is larger than the horizontal maximum dimension W1. 7 can be reduced in the vertical maximum dimension H1 (height dimension H1).

Thereby, it can suppress that the vertical direction dimension (height dimension) becomes large as the whole laser marking device 1, and the fall risk of the laser marking device 1 accompanying the increase in height dimension can be reduced.
As described above, in the pack mounting portion 7, the two slide rails 43 are parallel to the side surface of the rotating portion 11 (in other words, parallel to the tangential direction of the virtual circle centered on the central axis L 1). It is comprised so that it may be formed. Here, the direction parallel to the side surface of the rotating unit 11 includes both the horizontal direction and the vertical direction. In the present embodiment, the slide rail 43 is formed in parallel to the horizontal direction.

  By providing such a slide rail 43, the moving direction of the battery pack 5 when attaching / detaching the battery pack 5 is the horizontal direction, and there is no movement in the vertical direction. In this case, when the battery pack 5 is attached / detached, it is possible to prevent the upper region and the lower region of the outer surface of the housing 3 from interfering with the battery pack 5 from being interfered with the battery pack 5, and damage due to the interference occurs. Can be suppressed.

In particular, the laser marking device 1 of the present embodiment has a configuration in which the horizontal laser light passage portion 21 and the vertical laser light passage portion 23 are arranged in the upper region of the pack mounting portion 7, so When the moving direction is the vertical direction, the horizontal laser beam passage 21 and the vertical laser beam passage 23 may be damaged due to interference with the battery pack 5. On the other hand, in this embodiment, the moving direction of the battery pack 5 at the time of attachment / detachment is the horizontal direction, and the horizontal laser light passage portion 21 and the vertical laser light passage portion 23 are scratched due to interference with the battery pack 5. Therefore, the laser beam can be appropriately projected onto the object.

  In the laser marking device 1 of the present embodiment, the battery pack 5 has a shape in which the vertical maximum dimension H1 when mounted on the pack mounting part 7 is smaller than the horizontal maximum dimension W1, and the pack is mounted. In the part 7, the slide rail 43 is formed in parallel to the horizontal direction. The laser marking device 1 having such a configuration can reduce the distance between the two slide rails 43, and can suppress an increase in the height of the laser marking device 1.

[1-4. Laser light generator]
As described above, the laser light generation unit 9 includes the laser light emission unit 25 and the emission control unit 27.

Here, the arrangement position of the injection control unit 27 in the laser marking device 1 will be described.
As shown in FIG. 6, when assuming a virtual plane VF that is parallel to the slide rail 43 of the pack mounting portion 7 and includes the central axis L1, the internal region of the laser marking device 1 divided by the virtual plane VF is: It is divided into a first area C1 in which the pack mounting part 7 is included and a second area C2 in which the pack mounting part 7 is not included.

The ejection control unit 27 is disposed in the second region C2 of the two regions (the first region C1 and the second region C2) in the laser marking device 1.
In addition, since the pack mounting part 7 is provided in the first region C1, the battery pack 5 is disposed. The battery pack 5 is a relatively heavy component among the components of the laser marking device 1, and is disposed in the first region C1.

  In other words, the injection control unit 27 in the first region C1 in which the pack mounting unit 7 (battery pack 5) is arranged among the two regions (first region C1 and second region C2) divided by the virtual plane VF. Instead, it is arranged in a second region C2 different from the first region C1.

  As described above, in the two regions (first region C1 and second region C2) divided by the virtual plane VF, the pack mounting portion 7 (battery pack 5) and the injection control unit 27 are arranged in different regions. Compared with the case where the pack mounting part 7 (battery pack 5) and the injection control part 27 are arranged in the same region, the center of gravity of the laser marking device 1 can be brought closer to the central axis L1.

Thereby, it can suppress that the gravity center in the laser marking device 1 deviates to the battery pack side, and can suppress the risk of falling.
As shown in FIGS. 5 and 6, an adjustment weight 57 for adjusting the position of the center of gravity of the laser marking device 1 is arranged in the second region C2. The adjustment weight 57 is provided in the laser marking device 1 when the center of gravity of the laser marking device 1 is biased toward the battery pack only with other components in the laser marking device 1 and the laser marking device 1 may fall over.

  As shown in FIG. 6, the weight and arrangement position of the adjustment weight 57 are such that when the laser marking device 1 is viewed in plan, the center of gravity of the laser marking device 1 has three legs 33 (specifically, a grounding portion). It is adjusted (set) so that it is included in the triangular area with the apex. In the present embodiment, the adjustment weight 57 is disposed at a position where at least a part of the second region C2 intersects a plane that passes through the central axis L1 and is perpendicular to the virtual plane VF. Further, as shown in FIG. 5, the adjustment weight 57 is arranged such that its lower end is lower than the lower end of the battery pack 5 in the vertical direction (height direction).

[1-5. External power receiving unit]
As described above, the laser marking device 1 includes the external power supply connection portion 53 on the side surface of the rotating portion 11 of the housing 3, and the external power supply connection portion 53 can be electrically connected to an external power supply (AC adapter 71). It is configured.

  By providing such an external power supply connection unit 53, the laser marking device 1 can receive power from an external power supply different from the battery pack 5. As a result, the laser marking device 1 can emit laser light by supplying power from an external power source even when the state of the battery pack 5 is “the remaining charge amount is zero” or “failure state”. It becomes.

  The AC adapter 71 is an external power source whose output voltage is in the range of 4.5 to 5.5V. That is, the external power supply connection unit 53 is configured to be connected to an external power supply whose output voltage is in the range of 4.5 to 5.5V. An external power supply (AC adapter 71) configured so that the output voltage falls within the above range is widely distributed as a general-purpose product, and such an external power supply is easily available.

  As a result, even when the state of the battery pack 5 is “a state where the remaining charge amount is zero” or a “failure state”, the laser marking device 1 is supplied with power from the external power source (AC adapter 71). Light can be emitted.

[1-6. effect]
As described above, in the laser marking device 1 of the present embodiment, the pack mounting portion 7 is formed on the side surface of the housing 3, and the pack mounting portion 7 is parallel to the side surface of the rotating portion 11 (in other words, In this case, two slide rails 43 formed in parallel to the tangential direction of the virtual circle centered on the central axis L1 are provided. That is, the pack mounting portion 7 is configured to attach and detach the battery pack 5 by sliding the battery pack 5 along the slide rail 43.

  As described above, the method of detaching the battery pack 5 by sliding the battery pack 5 parallel to the side surface of the housing 3 is a method of moving the battery pack in a direction perpendicular to the outer surface of the housing 3 (insertion). The battery pack 5 can be arranged in a region away from the center position (center axis L1) of the housing 3 as compared with the method.

  Thereby, the influence of the arrangement region of the battery pack 5 on the arrangement region of the laser light generation unit 9 in the inner region of the housing 3 can be reduced. That is, it is possible to suppress an increase in the area occupied by the battery pack 5 inside the laser marking device 1, and it is possible to suppress a reduction in the degree of freedom of arrangement of each component inside the laser marking device 1.

  Since the laser marking device 1 has a configuration in which the pack mounting unit 7 can mount the chargeable / dischargeable battery pack 5, the battery pack 5 can be repeatedly used by charging, and therefore a primary battery (dry cell or the like) is used. Compared with, resource waste can be reduced.

Therefore, according to the laser marking device 1, it is possible to provide a laser marking device in which waste of resources is reduced and the degree of freedom of arrangement in each component housed therein is difficult to decrease.
In addition, when the laser marking device 1 is realized by changing the design based on the existing laser marking device, the arrangement area of each component (laser light generation unit, etc.) accommodated in the laser marking device is significantly changed. The battery pack 5 can be mounted without doing so.

Next, as described above, when the battery pack 5 is mounted on the pack mounting portion 7,
The vertical maximum dimension H1 is configured to be smaller than the horizontal maximum dimension W1 (H1 <W1). Thereby, it can suppress that the vertical direction dimension (height dimension) becomes large as the whole laser marking device 1, and the fall risk of the laser marking device 1 accompanying the increase in height dimension can be reduced.

  Next, as described above, in the pack mounting portion 7, the two slide rails 43 are parallel to the side surface of the rotating portion 11 (in other words, with respect to the tangential direction of the virtual circle centered on the central axis L1). Parallel) and formed in parallel to the horizontal direction.

  By providing such a slide rail 43, the moving direction of the battery pack 5 when attaching / detaching the battery pack 5 is the horizontal direction, and there is no movement in the vertical direction. In this case, when the battery pack 5 is attached / detached, it is possible to prevent the upper region and the lower region of the outer surface of the housing 3 from interfering with the battery pack 5 from being interfered with the battery pack 5, and damage due to the interference occurs. Can be suppressed.

Next, in the laser marking device 1, the housing 3 includes a base portion 13 and a rotating portion 11, and the pack mounting portion 7 is formed on the side surface of the rotating portion 11.
As described above, since the housing 3 includes the base portion 13 and the rotating portion 11, the projection direction of the laser light can be easily adjusted by the rotation of the rotating portion 11.

  In addition, by adopting a configuration in which the pack mounting portion 7 is formed on the side surface of the rotating portion 11, the energization path from the battery pack 5 to the laser light generating portion 9 extends over both the base portion 13 and the rotating portion 11. There is no need to place them. Thereby, this laser marking device 1 does not need to provide an energization path at a location where the relative position changes due to rotation, and can suppress the complication of the energization path.

  Next, in the laser marking device 1, the ejection control unit 27 includes the pack mounting unit 7 (battery pack 5) among the two regions (the first region C 1 and the second region C 2) in the laser marking device 1. It is arranged not in the first area C1 to be arranged but in the second area C2 different from the first area C1.

  As described above, in the two regions (first region C1 and second region C2) divided by the virtual plane VF, the pack mounting portion 7 (battery pack 5) and the injection control unit 27 are arranged in different regions. Compared with the case where the pack mounting part 7 (battery pack 5) and the injection control part 27 are arranged in the same region, the center of gravity of the laser marking device 1 can be brought closer to the central axis L1.

Thereby, it can suppress that the gravity center in the laser marking device 1 deviates to the battery pack side, and can suppress the risk of falling.
Next, the laser marking device 1 includes an external power supply connection unit 53 connected to an external power supply (AC adapter 71) that supplies power to the laser light generation unit 9. Therefore, the laser marking device 1 can receive power from an external power source (AC adapter 71) different from the battery pack 5.

  Therefore, the laser marking device 1 can emit laser light by supplying power from the external power source even when the state of the battery pack 5 is “the remaining charge amount is zero” or “the failure state”. Become.

The AC adapter 71 is an external power source whose output voltage is in the range of 4.5 to 5.5 V, and the external power source configured so that the output voltage is in the above range is widely distributed as a general-purpose product. Such an external power source is readily available.

  Therefore, even when the state of the battery pack 5 is “a state where the remaining charge amount is zero” or “a failure state”, the laser marking device 1 is supplied with power from the external power source (AC adapter 71). Can be injected.

Next, the laser marking device 1 includes a pack side transformer circuit 61 and an external power source side transformer circuit 63.
Thus, the pack side transformer circuit 61 and the external power source side transformer circuit 63 are provided, and the output voltage of the battery pack 5 and the external power source (AC adapter 71) is converted into a voltage suitable for driving the laser light generation unit 9 (transformation). ), Laser irradiation can be realized using power from various battery packs and various external power sources.

Next, in the laser marking device 1, the laser light generation unit 9 is configured to generate green laser light as the laser light.
The laser light generation unit 9 that generates a green laser has a larger power consumption than a laser light generation unit (laser element) that generates a red laser beam that has been widely used in the past, and thus is shorter than the conventional one. Power will be discharged over time.

  On the other hand, since the laser marking device 1 is configured to use the chargeable / dischargeable battery pack 5 as a power source, the waste of resources can be further suppressed as compared with the case of using a primary battery (dry cell). .

[3-1. overall structure]
Next, as a third embodiment, a third laser marking device 201 including an auxiliary support part for suppressing the overturn will be described.

  The third laser marking device 201 is configured by attaching an auxiliary support portion 211 to the laser marking device 1 of the first embodiment described above. The third laser marking device 201 includes a large battery pack 105 having a larger rated capacity than the battery pack 5 of the first embodiment. Therefore, in the following description, the third laser marking device 201 will be described focusing on the differences from the first embodiment. Moreover, about the structure similar to 1st Embodiment among the structures of 3rd Embodiment, the same code | symbol as 1st Embodiment is attached | subjected and description is abbreviate | omitted.

As shown in FIGS. 11 to 14, the third laser marking device 201 includes an auxiliary support portion 211.
The large battery pack 105 has a larger rated capacity than the battery pack 5 of the first embodiment. For this reason, the large battery pack 105 is larger in volume and heavier than the battery pack 5.

  The auxiliary support portion 211 is a U-shaped member with a sharp corner as a general shape, and includes a grounding portion 213 and two extending portions 215. The grounding portion 213 constitutes a portion corresponding to a U-shaped bottom portion, and the two extending portions 215 constitute portions corresponding to two U-shaped side portions, respectively. The auxiliary support portion 211 has two end portions on the U-shaped opening side (in other words, an end portion of the two extending portions 215 opposite to the grounding portion 213) via the connecting portion 217. It is attached to be able to rotate.

  The grounding portion 213 is formed in a long shape that connects the end portions of the two extending portions 215, and the length dimension thereof is a dimension that can be grasped by the user. The grounding portion 213 includes an inner member (not shown) as a skeleton and a covering member surrounding the inner member. The inner member is made of a hard resin material (for example, ABS resin) and has rigidity sufficient to withstand the weight of the third laser marking device 201. The covering material is made of an elastic material (for example, rubber, low-resilience urethane, low-resilience sponge, etc.) and can absorb the impact when it collides with the ground, etc., and has a non-slip function when placed on the ground. Can demonstrate. That is, the grounding portion 213 has its own surface made of an elastic material.

  The two extending portions 215 are formed so as to extend from the two connecting portions 217 to the grounding portion 213, respectively. Each of the two extending portions 215 is made of a hard resin material (for example, ABS resin) and has rigidity sufficient to withstand the weight of the third laser marking device 201.

  Each of the two connecting portions 217 includes an annular portion 217a and a male screw 217b. The connecting portion 217 is configured to fix the male screw 217b to the housing 3 while inserting the male screw 217b through a hole provided in the annular portion 217a. Thereby, the two connection parts 217 have connected the auxiliary support part 211 with the housing 3 in the form which can be rotated.

The rotation axis L2 (see FIG. 13) of the auxiliary support portion 211 by the two connecting portions 217 is set in the horizontal direction and parallel to the slide rail 43 (see FIG. 2) of the pack mounting portion 7. The position of the two connecting portions 217 in the housing 3 when viewed in plan from above the central axis L1 (in other words, the formation position of the female screw (not shown) to which the male screw 217b is fixed) is determined by the auxiliary support portion 211. When fixed to the position shown in FIG. 12 (hereinafter also referred to as a support position), the grounding portion 213 and the two extending portions 215 are in a state of surrounding at least the formation region of the pack mounting portion 7 on the side surface of the housing 3. Position (see FIG. 13).

  When the two connecting portions 217 are viewed from above the central axis L1 of the housing 3, the rotation axis L2 is disposed in a region of the housing 3 closer to the pack mounting portion 7 than the central axis L1 (see FIG. The formation position in the housing 3 is defined. Further, the two connecting portions 217 are arranged such that the rotation axis L2 is arranged at a position higher than the center of gravity GC (see FIG. 12) of the third laser marking device 201 in the housing 3 when viewed from the side. The formation position in the housing 3 is determined.

  As shown in FIG. 14, the auxiliary support portion 211 rotates around the connecting portion 217 (the rotation axis L2), so that the grounding portion 213 is at least the lowest position (a position indicated by a dotted line in the figure, support). It corresponds to a position) and is configured to be able to move in a range from a highest position in the drawing (a position indicated by a solid line) to a predetermined position (not shown) on the front side of the housing 3.

  The auxiliary support portion 211 is configured to be temporarily fixed (positioned) at least at a support position within a rotatable range by a positioning portion (not shown) provided in advance. The positioning portion is, for example, at a predetermined position in the circumferential direction centered on the rotation axis L2 in a portion where the auxiliary support portion 211 (specifically, the annular portion 217a) and the housing 3 are in contact with (opposed to) each other. Alternatively, a convex portion having rounded corners may be formed, and a concave portion that can be fitted to the convex portion may be formed on the other side. Even if the convex portion and the concave portion are fitted to each other, movement of the auxiliary support portion 211 relative to the housing 3 in the rotational direction is restricted, and the auxiliary support portion 211 can be temporarily fixed (positioned) at the support position. Good. The convex portion may be in a fixed form in which the protruding dimension is constant, or may be in a form in which the protruding dimension is variable by a spring or the like.

  When the auxiliary support portion 211 is disposed (temporarily fixed) at the support position, the grounding portion 213 is disposed in a region lower than the pack mounting portion 7 and has a gap with respect to the ground GND in contact with the three leg portions 33. It is configured to be arranged via G1 (see FIG. 12).

  Each of the three leg portions 33 is provided at the bottom of the housing 3 (plate portion 31) so as to abut the installation place of the third laser marking device 201, and the length dimension can be independently changed. (It can be expanded and contracted). Thereby, even when there is an inclination or a step in the installation place of the third laser marking device 201, the length of the three leg portions 33 is adjusted so that the central axis L1 is in the vertical direction. The posture of the 3 laser marking device 201 can be adjusted. FIG. 12 shows the third laser marking device 201 when each of the three leg portions 33 is in the shortest state.

  As shown in FIG. 12, in the third embodiment, the auxiliary support portion 211 is configured such that the ground GND (virtual ground) when the three leg portions 33 are in the shortest state and the third laser marking device 201 are tilted. Is set within a predetermined range (for example, within a range of 10 to 20 degrees), between the ground contact surface (the virtual surface in contact with the tip of the leg 33 and the tip of the auxiliary support 211). ing. The third laser marking device 201 is tilted by controlling the laser output to blink when the tilt angle of the third laser marking device 201 is equal to or greater than a predetermined notification angle θth (for example, 2 to 3 degrees). It has a function to notify the user of this.

That is, in the third laser marking device 201, the shape of the grounding portion 213 and the shape of the extending portion 215 in the auxiliary support portion 211 are determined so that the auxiliary angle θ1 is larger than the notification angle θth. Accordingly, when the third laser marking device 201 is supported by the auxiliary support portion 211, the laser output is always controlled to blink, and as a result, the third laser marking device 201 is sure to be in a tilted state. The user can be notified.

  Further, in the third embodiment, the auxiliary support portion 211 is configured so that the gap G1 with respect to the ground GND (virtual ground) when the three leg portions 33 are in the shortest state has a size that allows the user's hand to enter. The shape of 213 and the shape of the extending portion 215 are determined.

  Next, as shown in FIG. 15, when the auxiliary support portion 211 is disposed (temporarily fixed) at the support position, at least one of the grounding portions 213 in a plan view from the upper side of the central axis L <b> 1 of the housing 3. The grounding portion 213 is arranged such that a virtual line segment L3 connecting the portion and the central axis L1 intersects the pack mounting portion 7. In addition, in FIG. 15, the arrangement | positioning area | region of the earthing | grounding part 213 and the formation area of the pack mounting part 7 are each represented by the mesh pattern. In FIG. 15, a line segment connecting the part 213a and the central axis L1 in the grounding portion 213 is described as an example of the virtual line segment L3. The virtual line segment L3 is a virtual line segment that passes through at least a part of the grounding portion 213, and is a line segment that can be assumed at an arbitrary position in the range C3 illustrated in FIG. As shown in FIG. 15, in the third laser marking device 201, the auxiliary support portion 211 is configured such that the virtual line segment L <b> 3 always intersects the formation region of the pack mounting portion 7.

  That is, the auxiliary support portion 211 is configured to be rotatable, and when temporarily fixed at a support position within the rotatable range, the grounding portion 213 is arranged so that the virtual line segment L3 intersects the pack mounting portion 7. In addition, the grounding portion 213 is configured to be disposed through the gap G1 with respect to the ground GND (virtual ground) in a region lower than the pack mounting portion 7.

  Further, the auxiliary support portion 211 is configured to be usable as a handle portion for the user to grasp the grounding portion 213 when the grounding portion 213 is disposed above the housing 3 in the rotatable range. Yes. That is, the third laser marking device 201 is configured to be transportable by the user using the grounding portion 213 as a handle portion.

  As described above, the grounding portion 213 of the auxiliary support portion 211 exhibits a function of suppressing a fall by being fixed at a support position, and is also disposed above the housing 3 as a handle portion. It is configured to demonstrate.

[3-2. effect]
As described above, in the third laser marking device 201 of the third embodiment, the auxiliary support portion 211 is attached to the housing 3 in a form that can be moved by rotation.

  The auxiliary support part 211 is temporarily fixed (positioned) at a predetermined support position within its movable range, so that the grounding part 213 is arranged so that the virtual line segment L3 intersects the pack mounting part 7. In addition, the grounding portion 213 is arranged with respect to the ground GND (virtual ground) through the gap G1 in a region lower than the pack mounting portion 7.

  Even if the center of gravity of the third laser marking device 201 including such an auxiliary support portion 211 is biased toward the large battery pack 105 due to the weight of the large battery pack 105 mounted on the pack mounting portion 7, the third laser marking device 201 is completely overturned. Before, the auxiliary support part 211 (specifically, the grounding part 213) can contact the ground GND to support the third laser marking device 201.

Therefore, according to the 3rd laser marking device 201, by providing the auxiliary support part 211, even if it is a case where the large sized battery pack 105 with heavy weight is mounted | worn, a fall can be suppressed.
In addition, the third laser marking device 201 includes the auxiliary support portion 211 configured to be rotatable, so that the case where the auxiliary support portion 211 is fixed at the support position and the case where the auxiliary support portion 211 is not fixed are determined depending on the use situation. It is configured to be switchable. For example, when the third laser marking device 201 is used, the auxiliary support portion 211 is fixed at the support position, so that the fall can be suppressed. Alternatively, when the third laser marking device 201 is not used (during transportation and storage), the auxiliary support part 211 is freely movable (rotatable) at a position different from the support position. It can be used in a state suitable for transportation or storage.

  Next, in the 3rd laser marking device 201, the auxiliary | assistant support part 211 is equipped with the earthing | grounding part 213 which can be utilized as a handle part for a user to hold. As described above, the auxiliary support portion 211 includes the grounding portion 213 that can be used as a handle portion, so that the auxiliary support portion (a member for suppressing the fall) and the handle portion (a member for the user to grasp) are provided. It is not necessary to provide them separately, and an increase in the number of parts constituting the third laser marking device 201 can be suppressed.

  In particular, the auxiliary support portion 211 is configured so that the grounding portion 213 can move to a region higher than the upper end of the housing, and “a member that comes into contact with the ground to prevent toppling” and “a handle portion (grasped by the user). For example) ”is constituted by the same portion (grounding portion 213). By adopting such a configuration, compared to the case where the “member that comes into contact with the ground to prevent toppling” and the “grip part (member for gripping by the user)” are formed in different parts, auxiliary support is provided. The enlargement of the part 211 can be suppressed.

  Next, in the third laser marking device 201, the auxiliary support portion 211 is attached to the side surface of the housing 3 via the two connecting portions 217 (the annular portion 217a and the male screw 217b) and the two connecting portions 217. It is comprised so that rotation is possible centering on. The position of the two connecting portions 217 in the housing 3 when viewed from above the central axis L1 is such that the grounding portion 213 and the two extending portions 215 are located in the housing 3 when the auxiliary support portion 211 is fixed at the support position. It is the position which will be in the state which surrounds the formation area of the pack mounting part 7 at least among the side surfaces.

  Such a third laser marking device 201 has a configuration in which the auxiliary support portion 211 is attached to the side surface of the housing 3 through the two connecting portions 217, and therefore, compared to a configuration in which the auxiliary support portion 211 is attached through one connecting portion. Even when the weight of the third laser marking device 201 becomes heavy, it can be lifted using the auxiliary support portion 211. As a result, even if the third laser marking device 201 is heavy, the user grasps the grounding portion 213 (which corresponds to the handle portion at this time) of the auxiliary support portion 211 to grasp the third laser marking device 201. The container 201 can be transported stably.

  Further, the third laser marking device 201 assists the grounding portion 213 to move to a region lower than the pack mounting portion 7 by determining the positions of the two connecting portions 217 in the housing 3 as described above. By rotating the support portion 211, it is possible to easily realize the placement of the grounding portion 213 so that a predetermined condition is satisfied. The predetermined condition is that the grounding portion 213 is arranged so that the virtual line segment L3 intersects the pack mounting portion 7, and that the gap G1 is set to the ground GND (virtual ground) in a region lower than the pack mounting portion 7. In other words, the grounding portion 213 is disposed at a position interposed between them. By arranging the grounding portion 213 of the auxiliary support portion 211 at such a position, the third laser marking device 201 can be prevented from falling.

  Next, in the third laser marking device 201, the connecting portion 217 (rotating shaft L2) is formed at a position higher than the center of gravity GC of the third laser marking device 201 in the housing 3 (FIG. 12). reference).

In such a third laser marking device 201, when the user lifts the third laser marking device 201 by holding the grounding portion 213 (corresponding to the handle portion), the center of gravity GC is connected to the connecting portion 217. Therefore, the main body portion of the third laser marking device 201 excluding the auxiliary support portion 211 is in a stable state. For this reason, when the third laser marking device 201 is lifted by grasping the grounding portion 213, the main body portion excluding the auxiliary support portion 211 can be prevented from turning upside down, and the third portion in a stable state. The laser marking device 201 can be carried around.

Next, in the 3rd laser marking device 201, the earthing | grounding part 213 of the auxiliary | assistant support part 211 is a structure by which an own surface is formed with an elastic material.
By providing the auxiliary support portion 211 having such a configuration, when the third laser marking device 201 is tilted and the grounding portion 213 contacts the ground GND, the portion of the grounding portion 213 formed of an elastic material is Since the anti-slip function is exhibited, the third laser marking device 201 is more difficult to fall. When the grounding part 213 is used as a handle part, the surface of the grounding part 213 (in other words, the handle part) is formed of an elastic material, so that the user can connect the grounding part 213 (the handle part). When the third laser marking device 201 is transported by grasping the portion), the grounding portion 213 can be prevented from slipping and the third laser marking device 201 falling.

[3-3. Correspondence of wording]
Here, the correspondence between words will be described.
The third laser marking device 201 corresponds to an example of a laser marking device, the leg portion 33 corresponds to an example of a leg portion, the auxiliary support portion 211 corresponds to an example of an auxiliary support portion, and the grounding portion 213 is “identical”. The extended portion 215 corresponds to an example of the extended portion, and the connecting portion 217 corresponds to an example of the connecting portion.

[4. Fourth Embodiment]

The extension part 315 is formed thicker than the extension part 215, so that the load-bearing capacity is large. Even with a single extension part 315, the extension part 315 can be used for supporting the fourth laser marking device 301 to prevent overturning. The four-laser marking device 301 is configured to be usable for carrying it.

  The second auxiliary support portion 311 is rotatably attached to the housing 3 at the end portion of the extending portion 315 via a connecting portion 317 (annular portion 317a, male screw 317b (rotating shaft L2)). That is, the second auxiliary support portion 311 is attached to the housing 3 via the one connection portion 317 in a rotatable form.

  The second auxiliary support portion 311 rotates around the connecting portion 317 (rotation axis L2), so that the ground contact portion 313 is at least from the lowest position (position shown in FIG. 18; hereinafter also referred to as support position). A range up to a predetermined position (not shown) on the front side of the housing 3 can be moved via the highest position (position shown in FIG. 19).

  Similarly to the auxiliary support portion 211, the second auxiliary support portion 311 is configured to be temporarily fixed (positioned) at least at a support position within a rotatable range by a positioning portion (not shown) provided in advance. .

  When the second auxiliary support portion 311 is disposed (temporarily fixed) at the support position, the ground contact portion 313 is disposed in a region lower than the pack mounting portion 7 and is also against the ground GND that contacts the three leg portions 33.

The arrangement of the grounding portion 213, the pack mounting portion 7, the central axis L1, and the imaginary line segment L3 is the same as that shown in FIG.

  That is, the second auxiliary support portion 311 is configured to be rotatable, like the auxiliary support portion 211, and when temporarily fixed at the support position within the rotatable range, the virtual line segment L3 becomes the pack mounting portion. The grounding portion 313 is arranged so as to intersect with 7, and the grounding portion 313 is arranged with respect to the ground GND (virtual ground) via the gap G 1 in a region lower than the pack mounting portion 7. Yes.

  Next, as can be seen from FIG. 16, the position of the connecting portion 317 in the housing 3 depends on the movement area of the grounding portion 313 and the extending portion 315 when the second auxiliary support portion 311 is rotated. The position is set so as not to overlap the moving area of the large battery pack 105 during the detaching operation.

  Further, the second auxiliary support portion 311 is configured to be usable as a handle portion for the user to hold the grounding portion 313 when the grounding portion 313 is disposed above the housing 3 in the rotatable range. Has been. That is, the 4th laser marking device 301 is comprised so that a user can carry by using the grounding part 313 as a handle part.

  As described above, the grounding portion 313 of the second auxiliary support portion 311 exhibits a function of suppressing the fall by being fixed at the support position, and is disposed on the upper side of the housing 3 as a handle portion. It is comprised so that the function of may be demonstrated.

[4-2. effect]
As described above, in the fourth laser marking device 301 of the fourth embodiment, the second auxiliary support portion 311 is attached to the housing 3 in a form that can be moved by rotation.

  Similar to the third laser marking device 201, the fourth laser marking device 301 including the second auxiliary support portion 311 has a large-sized battery pack whose center of gravity depends on the weight of the large battery pack 105 mounted on the pack mounting portion 7. Even if it is inclined to the 105 side, the second auxiliary support part 311 (specifically, the grounding part 313) may contact the ground GND to support the fourth laser marking device 301 before it completely falls down. it can.

  In addition, the fourth laser marking device 301 includes the second auxiliary support portion 311 that is configured to be rotatable, so that the auxiliary support portion 211 is fixed at the support position or not depending on the use situation. And can be switched.

  Next, in the 4th laser marking device 301, the 2nd auxiliary | assistant support part 311 is provided with the earthing | grounding part 313 which can be utilized as a handle part for a user to hold. As described above, the second auxiliary support portion 311 includes the grounding portion 313 that can be used as a handle portion, so that the auxiliary support portion (a member for suppressing the fall) and the handle portion (a member for the user to grasp). Need not be separately provided, and an increase in the number of parts constituting the fourth laser marking device 301 can be suppressed.

It is configured to be rotatable about (rotating axis L2).

  The position of the connecting portion 317 in the housing 3 is determined by the movement region of the grounding portion 313 and the extending portion 315 when the second auxiliary support portion 311 is rotated, and the movement of the large battery pack 105 during the attaching / detaching operation to the pack attaching portion 7. It is a position that does not overlap the area.

  In such a 4th laser marking device 301, since the 2nd auxiliary support part 311 is the structure attached to the side surface of the housing 3 via one connection part 317, it is the structure attached via two connection parts. In comparison with this, the movement area of the grounding portion 313 and the extending portion 315 when the second auxiliary support portion 311 is rotated becomes smaller. Therefore, the position of the connecting portion 317 in the housing 3 (in other words, the female screw 317b to which the male screw 317b is fixed) is set so that the moving region of the grounding portion 313 and the extending portion 315 does not overlap the moving region of the large battery pack 105. In determining a screw (not shown), the degree of freedom in the position of the connecting portion 317 is increased.

The third auxiliary support part 411 is a U-shaped member with a sharp corner as a schematic shape, and includes a grounding part 413 and two extension parts (a hard extension part 415 and a soft extension part 416). In other words, the third auxiliary support portion 411 has a configuration in which a soft extending portion 416 is added to the second auxiliary support portion 311. That is, the grounding portion 413 corresponds to the grounding portion 313, and the extending portion 315 corresponds to the hard extending portion 415.

  The hard extending portion 415 and the soft extending portion 416 are formed so as to extend from different connecting portions 417 (annular portion 417a, male screw 417b (rotating shaft L2)) to the grounding portion 413, respectively. The hard extending portion 415 is made of a hard resin material (for example, ABS resin) that does not elastically deform, and has rigidity that can withstand the weight of the fifth laser marking device 401. The soft extension 416 is made of a soft material (for example, rubber) that can be elastically deformed. The soft extension part 416 is formed with a smaller thickness than the hard extension part 415 (see FIGS. 20 and 22). The width dimension is small (see FIG. 21).

  The soft extension portion 416 is disposed at a position where its own movement trajectory when the third auxiliary support portion 411 is rotated overlaps with the movement area when the large battery pack 105 is attached / detached, and the hard extension portion 415 is the third auxiliary support portion. The movement trajectory of the part 411 is arranged at a position where it does not overlap the movement area when the large battery pack 105 is attached / detached.

  When the third auxiliary support part 411 is arranged (temporarily fixed) at the support position (position shown in FIGS. 20 and 21), the grounding part 413 is arranged in a region lower than the pack mounting part 7 and three It is comprised so that it may arrange | position via the clearance gap G1 (refer FIG. 21) with respect to the ground GND which contact | abuts the leg part 33.

  Further, the third auxiliary support portion 411 is configured to be usable as a handle portion for the user to grasp the grounding portion 413 when the grounding portion 413 is disposed above the housing 3 in the rotatable range. (See FIG. 22).

[5-2. effect]
As described above, in the fifth laser marking device 401 of the fifth embodiment, the third auxiliary support portion 411 is attached to the housing 3 in a form that can be moved by rotation.

  Similar to the fourth laser marking device 301, the fifth laser marking device 401 including the third auxiliary support portion 411 has a center of gravity that is located on the battery pack side due to the weight of the large battery pack 105 mounted on the pack mounting portion 7. The third auxiliary support portion 411 (specifically, the grounding portion 413) can contact the ground GND and support the fifth laser marking device 401 before it completely falls down.

Next, the fifth laser marking device 401 includes a third auxiliary support portion 411 having two extending portions (a hard extending portion 415 and a soft extending portion 416) formed of different materials.
The soft extending portion 416 is disposed at a position where its own movement trajectory when the third auxiliary support portion 411 is rotated overlaps with the moving region when the large battery pack 105 is attached / detached, and the hard extending portion 415 includes the third extending portion 415. The auxiliary support part 411 is arranged at a position where its own movement trajectory during rotation of the auxiliary support part 411 does not overlap with the movement area when the large battery pack 105 is attached / detached.

  In the fifth laser marking device 401, since the soft extending portion 416 can be elastically deformed, even when the large battery pack 105 is attached or detached, the soft extending portion 416 and the large battery pack 105 may interfere with each other. Since the soft extending portion 416 is elastically deformed, the attaching / detaching operation of the large battery pack 105 can be continued.

It is configured to be. In other words, the eighth laser marking device 701 is configured to be transportable by using the handle portion 714. At this time, the grounding unit 713 can support the large battery pack 105 by contacting the large battery pack 105.

  The slide type auxiliary support portion 711 configured in this manner is fixed at the support position, thereby exhibiting the function of suppressing the overturn by the grounding portion 713 and being disposed at the uppermost position in the slidable range. The handle portion 714 functions as a handle portion.

[8-2. effect]
As described above, in the eighth laser marking device 701 of the eighth embodiment, the slide type auxiliary support portion 711 is attached to the housing 3 in such a manner that it can be moved by sliding.

  The slidable auxiliary support portion 711 is temporarily fixed (positioned) at a predetermined support position within its movable range (slidable range), so that the virtual line segment L3 intersects with the pack mounting portion 7. Thus, the grounding portion 713 is disposed, and the grounding portion 713 is disposed with respect to the ground GND (virtual ground) via the gap G1 in a region lower than the pack mounting portion 7.

  Even if the center of gravity of the eighth laser marking device 701 including such a slide type auxiliary support portion 711 is biased toward the large battery pack 105 due to the weight of the large battery pack 105 mounted on the pack mounting portion 7, it is completely Before the tipping over, the slide type auxiliary support portion 711 (specifically, the grounding portion 713) can contact the ground GND to support the eighth laser marking device 701.

  Therefore, according to the eighth laser marking device 701, by providing the slide type auxiliary support portion 711, it is possible to suppress the fall even when the heavy battery pack 105 is attached.

  In addition, the eighth laser marking device 701 includes a slide-type auxiliary support portion 711 configured to be slidable, so that the slide-type auxiliary support portion 711 is fixed to the support position according to the use situation. It is configured so that it can be switched between when it does not. For example, when the eighth laser marking device 701 is used, it is possible to suppress the fall by fixing the slide type auxiliary support portion 711 to the support position. Alternatively, when the eighth laser marking device 701 is not used (during transportation), the slide type auxiliary support portion 711 is placed at the uppermost position, so that it can be used in a state suitable for transportation. Become.

  Next, in the eighth laser marking device 701, the slide type auxiliary support portion 711 includes a grounding portion 713 and a handle portion 714. By using the slide-type auxiliary support portion 711 having such a configuration, it is not necessary to separately provide an auxiliary support portion (a member for suppressing overturning) and a handle portion (a member for grasping by the user). An increase in the number of parts constituting the 8-laser marking device 701 can be suppressed.

Next, in the eighth laser marking device 701, the slide type auxiliary support portion 711 is configured to be moved by sliding and to be provided in different parts of the grounding portion 713 and the handle portion 714. Thereby, in the 8th laser marking device 701, the movement work of the slide type auxiliary support part 711 (for example, the work of moving from the support position to another position, etc.) can be easily performed, so that the state suitable for the overturning suppression is achieved. And switching to a state suitable for transportation becomes easy.

  Next, in the eighth laser marking device 701, the male screw 717b (base axis L4) of the connecting portion 717 is formed at a position higher than the center of gravity GC of the eighth laser marking device 701 in the housing 3 ( (See FIG. 29).

  In such an eighth laser marking device 701, when the user lifts the eighth laser marking device 701 by grasping the handle portion 714, the center of gravity GC is lower than the male screw 717b of the connecting portion 717. Therefore, the main body portion of the eighth laser marking device 701 excluding the slide type auxiliary support portion 711 is in a stable state. For this reason, when the handle portion 714 is grasped and the eighth laser marking device 701 is lifted, it is possible to suppress the main body portion excluding the slide type auxiliary support portion 711 from rotating upside down and being in a stable state. Then, the eighth laser marking device 701 can be carried.

  Next, in the eighth laser marking device 701, the grounding portion 713 and the handle portion 714 of the slide type auxiliary support portion 711 are each configured such that their surfaces are formed of an elastic material.

  By providing the slide type auxiliary support portion 711 having such a configuration, the eighth laser marking device 701 is formed of an elastic material in the grounding portion 713 when the grounding portion 713 contacts the ground GND by tilting. Since the portion exhibits the anti-slip function, the eighth laser marking device 701 is more difficult to fall. Further, since the surface of the handle portion 714 is formed of an elastic material, when the user grips the handle portion 714 and transports the eighth laser marking device 701, the handle portion 714 slips and becomes the eighth. It is possible to suppress the laser marking device 701 from falling.

  For example, in the above embodiment, the configuration using the AC adapter as the external power source connected to the external power source connection unit has been described. However, the external power source is not limited to the AC adapter, and other types such as a DC adapter are used. An external power supply may be used.

In the above embodiment, the configuration in which the output voltage of the AC adapter is 4.5 V to 5.5 V has been described, but the output voltage of the adapter is not limited to such a range. For example, a dedicated adapter instead of a general-purpose adapter may be prepared, and the output voltage may be equal to or lower than the battery pack voltage and higher than the voltage suitable for the laser light generation unit. In this case, in the block diagram of FIG. 7, the pack side switch unit 51a is directly connected to the contact point a of the changeover switch 65, the external power supply side switch unit 51b is directly connected to the contact point b of the changeover switch 65, and the contact point of the changeover switch 65. c
It is possible to adopt a configuration in which a pack side transformer circuit 61 is provided between the injection control unit 27 and the injection control unit 27. Thereby, the external power supply side transformer circuit 63 can be omitted, and the electrical configuration of the laser marking device can be simplified.

  Further, in the above-described embodiment, the configuration in which the voltage is stepped down by the pack side transformer circuit 61 and the voltage is stepped up by the external power source side transformer circuit 63 has been described, but a transformer circuit that can be stepped up and down may be used instead. Specifically, in the block diagram of FIG. 7, the pack-side switch unit 51a is directly connected to the contact a of the changeover switch 65, the external power supply side switch unit 51b is directly connected to the contact b of the changeover switch 65, and the changeover switch 65 is connected. A configuration may be adopted in which a transformer circuit capable of step-up / step-down is provided between the contact c and the injection control unit 27. This transformer circuit is configured to convert the input voltage into a voltage suitable for driving the laser light generation unit (step-down or step-up).

In the above-described embodiment, the configuration including the external power supply connection unit has been described. However, the configuration without the external power supply connection unit may be used.
Furthermore, the color of the emitted laser light is not limited to green, but may be other colors such as red.

Further, the external shape of the housing is not limited to the above shape, and may be, for example, a cylindrical shape or a polygonal prism shape.
In the above-described embodiment, a configuration including a mechanical gimbal mechanism has been described. However, a configuration including an electronic gimbal mechanism may be used.

  Furthermore, although the said embodiment demonstrated the structure provided with the mechanism in which the laser beam emission part 25 is set to either a fixed state or a rocking | fluctuation state by the stopper which operate | moves in conjunction with the operation switch 51, this was demonstrated. In addition to such a mechanism, a configuration including an operation unit that can set the laser light emitting unit 25 in a fixed state without depending on the state of the operation switch 51 may be employed.

  Furthermore, in the above-described embodiment, the configuration in which the sliding direction when the battery pack 5 is mounted is changed from the left direction to the right direction in FIG. 3 is described, but the sliding direction when the battery pack 5 is mounted is limited to such a direction. In other words, the battery pack 5 may be mounted by sliding from the right to the left.
