[0003] [Patent Document 1] Japanese Patent Publication No. 2022-10621 Summary of the Invention [Problem to be solved by the invention]
[0004] To simplify the assembly process, the lighting fixture is not fastened with screws, but is instead held in place within the tool body by, for example, a rib on the housing or a separately provided holder. This disclosure enables various interior parts, including the lighting fixture, to be efficiently assembled within the housing. [Means for solving the problem]
[0005] According to one aspect of the present disclosure, a driving tool has a main housing including, for example, a first housing and a second housing stacked on top of each other. For example, an electric motor is housed between the first housing and the second housing. For example, a driving mechanism operated by the electric motor is housed between the first housing and the second housing. For example, a magazine that houses driving tools is attached to the main housing. For example, an internal component provided in the first housing is held from the second housing side by a holder. For example, the holder has a wire holding portion that holds electrical wires on the second housing side.
[0006] Therefore, the interior part is held from the second housing side by the holder, which improves the ease of assembly of the interior part to the first housing. Also, the wire holding portion of the holder improves the ease of assembly of the electric wires to the main housing. [Brief explanation of the drawings]

[0008] In one or more embodiments, the interior component is, for example, a lighting fixture. Therefore, the lighting fixture is held by the holder and assembled to the first housing. This simplifies the assembly process of the lighting fixture to the housing.
[0009] In one or more embodiments, a controller that controls the operation of, for example, an electric motor is housed in the main body housing. For example, one side of the electrical wiring is connected to the controller. For example, the other side of the electrical wiring is connected to an electrical component disposed in the magazine. This allows the electrical wiring to be routed compactly between the controller and the magazine side via the holder.
[0010] In one or more embodiments, a sensor for detecting the remaining number of driving tools is provided in the magazine. For example, the other side of the electrical wiring is connected to the sensor. This allows for compact wiring between the controller and the sensor via the holder.
[0011] In one or more embodiments, for example, the wire holding portion of the holder has a first opening for receiving the electric wire and a second opening that is narrower than the first opening and is located closer to the magazine than the first opening. For example, the electric wire is guided from the first opening to the second opening. This allows the electric wire to be routed compactly through the holder, and speeds up the assembly work of the electric wire.
[0012] In one or more embodiments, a wire holder for holding the electrical wires is provided, for example, on the magazine, thereby facilitating the wiring work of the electrical wires on the magazine side.
[0013] In one or more embodiments, for example, the wire holder on the magazine side has a first opening for receiving the electrical wire and a second opening that is wider than the first opening and is located closer to the main body housing than the first opening. For example, the electrical wire is guided from the first opening toward the second opening. Therefore, the electrical wire can be quickly routed from the magazine side toward the main body housing side.
[0014] In one or more embodiments, for example, the wire holding portion of the holder has a first opening through which a first portion of the electrical wire on the controller side passes and a second opening through which a second portion of the electrical wire on the magazine side passes. The second opening is located closer to the second housing than the first opening. Therefore, the electrical wire is routed three-dimensionally from the first housing side to the second housing side through the first opening and the second opening.
[0015] In one or more embodiments, the driving mechanism includes, for example, a compression spring, a driver that drives the driving tool by using the biasing force of the compression spring, and a lift mechanism that moves the driver using an electric motor to compress the compression spring. Therefore, in a mechanical spring driving tool such as a tacker, the work of assembling interior components such as lighting fixtures and wiring electrical wiring to prevent blank driving is improved. [Example]
[0016] 1 to 3, in this embodiment, a mechanical spring type tacker that uses the biasing force of a compression coil spring as a striking force (driving force) is exemplified as the driving tool 1. The exemplified tacker is a rechargeable tacker that can be equipped with a rechargeable battery as a power source. The driving tool 1 drives a U-shaped driving tool T, called a staple, into a workpiece W to be driven.
[0017] The driving tool 1 comprises a tool body 10, a motor housing 12 housing an electric motor 13 as a drive source, a grip 16 held by the user, a magazine 19 for loading a large number of driving tools T, and a power supply 20. The tool body 10 comprises a main body housing 11 housing a lift mechanism 30, a driving mechanism 40, and a recoil absorption mechanism 50. In the following description, the driving direction of the driving tool T is referred to as the front side, and the opposite direction as the rear side. The user is positioned behind the driving tool 1 and holds the grip 16. The up-down and left-right directions are used as a reference for the user.
[0018] The tool body 10, motor accommodating section 12, grip section 16, and power supply section 20 form a single main body housing 11. The main body housing 11 has a left-right half structure with a first housing 11L on the left side and a second housing 11R on the right side stacked on top of each other. When the first housing 11L and the second housing 11R are separated from each other, the interior of the tool body 10, motor accommodating section 12, grip section 16, and power supply section 20 are exposed.
[0019] The front part of the tool body 10 has a driving nose part 2 that guides a driver 3 for striking the driving tool in the driving direction. The driver 3 advances through the driving passage of the driving nose part 2, striking the driving tool T and driving it out from the ejection port 2a at the front end part. One driving tool T ejected from the ejection port 2a is driven into the workpiece W to be driven.
[0020] A contact arm 4 is provided on the driving nose 2. The contact arm 4 extends back and forth along the driving nose 2. The contact arm 4 is supported so that it can move back and forth relative to the driving nose 2. The front end of the contact arm 4 is located forward of the front end (injection port 2a) of the driving nose 2. The contact arm 4 is biased relatively forward by a compression spring 5 interposed between the contact arm 4 and the driving nose 2.
[0021] By pressing down the driving tool 1 with the front end of the contact arm 4 in contact with the workpiece W, the contact arm 4 is retracted relative to the driving nose 2 against the compression spring 5. The driving operation is performed when the contact arm 4 is moved to the retracted position (ON operation).
[0022] The retracted position of the contact arm 4 is detected by a contact arm sensor 6 located on the front side of the driving mechanism 40. A single microswitch is used for the contact arm sensor 6. A detection arm portion 4a is integrally formed with the contact arm 4. When the contact arm 4 is retracted, the proximity of the detection arm portion 4a turns on the contact arm sensor 6. A detection signal from the contact arm sensor 6 is input to a controller 23, which will be described later. The driving operation is controlled by the controller 23.
[0023] The motor housing 12 and the grip portion 16 extend downward from the bottom of the tool body 10. The motor housing 12 is on the front side, and the grip portion 16 is on the rear side, extending substantially parallel to each other. The front motor housing 12 houses the electric motor 13, which is the drive source for the lift mechanism 30. As shown in Figure 3, the motor axis M of the electric motor 13 extends vertically in a direction that intersects (is perpendicular to) the driving direction (front-rear direction).
[0024] A magazine 19 is connected to the driving nose 2. The magazine 19 extends downward from the underside of the driving nose 2 along the front side of the motor housing 12. The magazine 19 is loaded with connected driving tools, which are U-shaped driving tools T called staples, temporarily fastened together in parallel. Details of the magazine 19 will be described later.
[0025] A space is provided between the motor housing 12 on the front side and the grip portion 16 on the rear side for the user to insert one of their hands. The grip portion 16 can be grasped with the hand inserted into this space. A trigger 17 is provided on the top of the grip portion 16, which the user pulls (turns on) with their fingertip. A trigger sensor 18 is installed behind the trigger 17. When the trigger 17 is pulled rearward, the trigger sensor 18 turns on. The electric motor 13 starts when the trigger sensor 18 is turned on as one of the conditions.
[0026] A power supply unit 20 is provided across the motor housing unit 12 and the lower part of the grip unit 16. A battery attachment unit 21 is provided on the underside of the power supply unit 20. One battery pack 22 can be attached to the battery attachment unit 21. Electricity from the attached battery pack 22 is mainly supplied as power for the electric motor 13.
[0027] The battery pack 22 is a generally rectangular parallelepiped, slide-mounted lithium-ion battery that can be removed from the battery mounting portion 21 and charged with a separately provided charger for repeated use. The battery pack 22 is also a highly versatile battery pack that can be used as a power source for other power tools, such as rechargeable screwdrivers and cutting tools. The battery pack 22 is attached to the battery mounting portion 21 by sliding it from rear to front. The battery mounting portion 21 has a rail receiver for slide attachment.
[0028] The battery mounting portion 21 accommodates a controller 23 that houses a control circuit board and a power supply circuit board for controlling the operation of the electric motor 13 .
[0029] 3 and 4, the driving mechanism 40 includes a driver base 41 that supports the driver 3, a mechanism frame 46 that supports the driver base 41 so that it can move back and forth, and a compression spring 42 that urges the driver base 41 in the driving direction. The urging force of the compression spring 42 serves as the impact force that strikes the driving tool T.
[0030] The rear of the driver 3 is connected to the top of the driver base 41 via a connecting pin 3a. The driver 3 is a long, thin plate that reciprocates back and forth within the driving passage of the driving nose 2. The front of the mechanism frame 46 has an elastic member 44 to absorb impacts when the driver base 41 is at the forward end position.
[0031] The driver 3 is returned to the rear end position by a lift mechanism 30 driven by an electric motor 13. The rotational output of the electric motor 13 is reduced in speed by a reduction gear box 14 incorporating a planetary gear train 14a and output to an output gear 15. The output gear 15 is meshed with an idle gear 31.
[0032] The idle gear 31 is meshed with one lift gear 32. The idle gear 31 and the lift gear 32 are each rotatably supported on the upper surface of a mechanism base 33. A first engagement portion 34 and a second engagement portion 35 are provided on the upper surface of the lift gear 32. The first engagement portion 34 and the second engagement portion 35 are cylindrical protrusions of approximately the same diameter, and are each provided to protrude upward. The amount of upward protrusion of the first engagement portion 34 is smaller than that of the second engagement portion 35.
[0033] A first engagement receiving portion 43 and a second engagement receiving portion 47 are integrally provided on the lower surface of the driver base portion 41. The first engagement receiving portion 43 and the second engagement receiving portion 47 are each provided to protrude downward from the lower surface of the driver base portion 41. The amount of downward protrusion of the first engagement receiving portion 43 on the rear side is greater than that of the second engagement receiving portion 47 on the front side.
[0034] By rotating the lift gear 32 once, the first engaging portion 34 is engaged with the front surface of the first engaging receiving portion 43 (the state shown in FIG. 3) and the second engaging portion 35 is engaged with the front surface of the second engaging receiving portion 47 are successively achieved. This causes the driver base 41 to return from the forward end position to the backward end position. By returning the driver base 41 to the rear, the compression spring 42 is compressed and the impact force is increased.
[0035] The standby position (initial position) of the driver 3 is set to a position just before the retracted end position. The state in which the driver 3 is positioned at the standby position corresponds to the initial state of the driving tool 1.
[0036] In the initial state of the driving tool 1, the driving operation starts on the condition that the contact arm 4 is retracted (contact arm sensor 6 is turned on) and the trigger 17 is pulled (trigger sensor 18 is turned on). When the contact arm sensor 6 is turned on and the trigger sensor 18 is turned on, power supply to the electric motor 13 is started and the electric motor 13 is started. When the electric motor 13 is started with the driver 3 in the standby position, the rotation of the lift gear 32 causes the driver 3 to reach the retracted end.
[0037] The retraction end position of the driver 3 is detected by a retraction end sensor 7. The retraction end sensor 7 is disposed on the rear side of the driving mechanism 40. A microswitch is used for the retraction end sensor 7. The retraction end position of the driver 3 is detected when the first engagement receiving portion 43 approaches the retraction end sensor 7.
[0038] When the retraction end sensor 7 turns on, a start timer that manages the start time of the electric motor 13 is activated. The start time (stop timing) of the electric motor 13 is set to the time it takes for the driver 3 to move from the retraction end position detected by the retraction end sensor 7, pass through the forward end position (driving position), and return to a standby position just before the retraction end position. The start time of the electric motor 13 is managed by the start timer, so that the driver 3 is returned from the forward end position after driving to the standby position (initial position) at the rear.
[0039] Immediately after the driver 3 reaches the retracted end position, the lift gear 32 further rotates, causing the second engagement portion 35 to disengage from the second engagement receiving portion 47. As a result, the driver base portion 41 moves forward due to the biasing force of the compression spring 42, and the driver 3 drives the bolt into the drive hole.
[0040] After the driving operation, the electric motor 13 continues to operate. This causes the lift gear 32 to continue to rotate, and the driver base 41 is returned rearward from the forward end position. When the driver 3 is returned to the standby position, the electric motor 13 is stopped by a timer function, and the lift mechanism 30 is stopped. This completes one driving operation.
[0041] A pair of left and right recoil absorbing mechanisms 50 are arranged along the lower side of the driving mechanism 40. The recoil absorbing mechanisms 50 absorb the recoil during impact. Each of the left and right recoil absorbing mechanisms 50 has a counterweight 51 and a recoil absorbing spring 52 that urges the counterweight 51 rearward (in the direction opposite to the driving direction). The counterweight 51 moves synchronously with the driver 3 in the opposite direction via meshing between the rack gear and the synchronous gear. The left and right counterweights 51 move synchronously with the driver 3 in the direction opposite to the driving direction during driving, thereby absorbing the recoil during driving. This improves the operability and ease of use of the driving tool 1.
[0042] 1 and 2, one lighting device 55 is provided on the front surface of the tool body 10. The lighting device 55 is provided on the front surface of the first housing 11L on the left side. Therefore, the lighting device 55 is positioned offset to the left side with respect to the magazine 19. This allows the lighting device 55 to brightly illuminate the driving area without being shaded by the magazine 19.
[0043] The lighting device 55 uses one or more light-emitting diodes (LEDs) mounted on a board. As shown in Fig. 6, the lighting device 55 is held by a rectangular rib-shaped interior part holder 11a provided on the inner surface of the first housing 11L on the left side. The interior part holder 11a holds the lighting device 55 so that it cannot move mainly in the inner surface direction of the first housing 11L (in the up-down and front-rear directions).
[0044] The holder 56 is inserted into the interior component holding portion 11a and assembled. The holder 56 is inserted from the second housing 11R side (right side). This presses the lighting device 55 toward the second housing 11R from the interior component holding portion 11a so that it cannot be removed. Therefore, by assembling the holder 56, the lighting device 55 is held in the interior component holding portion 11a of the first housing 11L so that it cannot move in any direction.
[0045] 8 to 10 show the holder 56 alone before being assembled to the interior component holding portion 11a. The holder 56 has a generally rectangular tubular body that is open on the top and right sides. The holder 56 has a front wall 56a, a rear wall 56b, a left wall 56c, and a bottom 56d.
[0046] A first opening 56g is defined between the right edge of the front wall 56a and the right edge of the rear wall 56b, allowing a first portion 60a of the electrical wiring 60 to pass through. A groove-shaped second opening 56e that opens at the upper end is provided in the front wall 56a. The second opening 56e extends vertically. The second opening 56e extends to about the middle of the height of the front wall 56a. The second opening 56e has a narrower opening width than the first opening 56g. A second portion 60b of the electrical wiring 60 passes through the second opening 56e. The second opening 56e mainly functions as a wiring holding portion for holding the electrical wiring 60.
[0047] A guide wall 56f is provided on the right edge of the rear wall 56b. The guide wall 56f is provided in a region below the rear wall 56b in the height direction. The guide wall 56f protrudes in a direction inclined diagonally rearward and to the right. The guide wall 56f serves to guide the electrical wiring 60 into the first opening 56g.
[0048] A positioning wall 56h is provided on the left edge of the rear wall 56b. The positioning wall 56h is provided in a region below the rear wall 56b in the height direction. The positioning wall 56h has approximately the same height as the guide wall 56f. The positioning wall 56h protrudes rearward. The positioning wall 56h protrudes flush with the left wall 56c. The positioning wall 56h positions the holder 56 in the front-rear and left-right directions relative to the interior component holding portion 11a.
[0049] A pressing portion 56i is provided on the underside of the bottom portion 56d. As shown in Fig. 6, the lighting fixture 55 is pressed down by the pressing portion 56i. During the assembly process, the bottom portion 56d of the holder 56 is inserted into the interior part holding portion 11a holding the lighting fixture 55, thereby holding the lighting fixture 55 in the interior part holding portion 11a. In this way, the lighting fixture 55 is assembled to the inner surface of the first housing 11L.
[0050] As shown in Figure 5, a pusher 19c biased in the feed direction by a compression spring 19b is provided inside the magazine 19. The loaded connecting driving tools are pitch-fed by the pusher 19c toward the driving nose 2 in conjunction with the driving operation of the tool body 10. This allows the driving tools T to be supplied one by one into the driving passage.
[0051] Therefore, as the number of driving tools T remaining in the magazine 19 decreases as they are consumed, the pusher 19c moves toward the driving nose 2. A detection unit 19d is integrally formed with the pusher 19c. As shown in FIG. 3, a magazine sensor 19e is disposed above the detection unit 19d (forward in the feed direction). Like the contact arm sensor 6 and the retraction end sensor 7, the magazine sensor 19e also uses a microswitch. The magazine sensor 19e detects the number of driving tools T remaining in the magazine 19 (for example, zero in this embodiment).
[0052] When the last driving tool T supplied to the driving passage of the driving nose section 2 is driven in, the pusher 19c moves to the uppermost position (the frontmost position in the feed direction). This causes the magazine sensor 19e to be pressed by the detection section 19d and turn on. When the magazine sensor 19e turns on, it is determined that there are no more driving tools T remaining in the magazine 19, and subsequent driving operations are restricted. This prevents empty driving. Preventing empty driving prevents damage to the material being driven in advance. When the magazine 19 is replenished with driving tools T, the pusher 19c moves back downward (rearward in the feed direction), allowing the driving operation to be resumed.
[0053] A regulating lever 19a for adjusting the driving depth is provided at the front of the magazine 19. The position of the regulating lever 19a can be adjusted forward or backward by rotating an adjustment dial 19f. This makes it possible to adjust the driving depth of the driving tool T into the workpiece W. The contact arm 4 is retracted by pushing down the driving tool 1 until the regulating lever 19a abuts against the workpiece W.
[0054] 3 and 7, the other side of the electrical wiring 60 is connected to the magazine sensor 19e. One side of the electrical wiring 60 is connected to the controller 23. The electrical wiring 60 electrically connecting the magazine sensor 19e to the controller 23 uses, for example, two lead wires. The controller 23 has a generally flat plate shape, with a control board 23b housed in a shallow rectangular case 23a that is open at the top and insulated with a resin mold. The controller 23 is disposed within the power supply unit 20 and above the battery mounting unit 21.
[0055] A detection signal from the magazine sensor 19e is input to the controller 23 via an electrical wiring 60. The driving operation is controlled based on the input detection signal from the magazine sensor 19e. The electrical wiring 60 is routed along the right side surface of the magazine 19 and the inside of the motor housing portion 12. The electrical wiring 60 is connected to one another by a connector 61 at one location. The connector 61 is elastically sandwiched between a first rib 61a and a second rib 61b provided on the right side of the magazine 19. This prevents the connector 61 from falling off from the right side of the magazine 19.
[0056] A wiring holding portion 62 is provided on the right side of the magazine 19. The wiring holding portion 62 of the magazine 19 is provided on the controller 23 side (downstream in the transmission direction of the detection signal) with respect to the connector 61. The wiring holding portion 62 has a first opening 62a and a second opening 62b. The first opening 62a is provided in a third rib 62c extending in the front-rear direction. The first opening 62a has a groove shape that is cut leftward from the right edge of the third rib 62c. The opening width of the first opening 62a is formed narrow enough to allow the electrical wiring 60 to be pushed in and elastically held.
[0057] The second opening 62b is disposed downstream of the first opening 62a (toward the motor accommodating portion 12). The second opening 62b is provided between the fourth rib 62d and the fifth rib 62e. The upper fourth rib 62d extends in the front-to-rear direction. The lower fifth rib 62e is provided along an inclined direction that shifts upward toward the rear. The second opening 62b is formed between the rear portion of the upper fourth rib 62d and the rear portion of the lower fifth rib 62e. The opening width of the second opening 62b is wider than that of the first opening 62a. The inclined lower fifth rib 62e guides the electrical wiring 60 toward the second opening 62b.
[0058] The holder 56 attached to the first housing 11L is located behind the second opening 62b. The second opening 56e of the holder 56 faces the second opening 62b on the magazine 19 side at approximately the same height (same position in the left-right direction). Therefore, the electrical wiring 60 passing through the second opening 62b is guided directly into the second opening 56e of the holder 56. The second portion 60b of the electrical wiring 60 is guided into the second opening 56e.
[0059] The electrical wiring 60 that passes through the second opening 56e is routed to the right within the holder 56. As a result, the electrical wiring 60 is drawn out from the right side of the first opening 56g (the bottom 56d side). In this way, the wiring path of the electrical wiring 60 is changed in the left-right direction (the longitudinal direction of the holder 56) between the first opening 56g and the second opening 56e of the holder 56. As a result, the electrical wiring 60 is routed three-dimensionally by the holder 56.
[0060] The electrical wiring 60 drawn out from the first opening 56g of the holder 56 is routed along the inside of the front part of the motor accommodating portion 12 and connected to the control board 23b of the controller 23.
[0061] In the process of assembling the driving tool 1, the second housing 11R is placed on the first housing 11L and screwed together with the lighting device 55 held by the holder 56 and the electrical wiring 60 attached along the inner surface of the first housing 11L via the wiring holding portion of the holder 56. As shown in Fig. 6, the front portion of the second housing 11R is cut out in an area to the right of the lighting device 55 to provide a relief portion 11b. This allows the second housing 11R to be assembled to the first housing 11L while visually checking the state of the lighting device 55 attached to the holder 56 and the state of the electrical wiring 60 through the relief portion 11b.
[0062] A separately prepared holder cover 57 is attached to the right of the holder 56. The holder cover 57 is screwed to the second housing 11R with, for example, a fixing screw 58. This closes the relief portion 11b of the second housing 11R and holds the holder 56 so that it cannot move to the right (towards the second housing 11R). Since the holder 56 is held by the holder cover 57 so that it cannot move to the right, the lighting fixture 55 as an interior part is assembled inside the main housing 11 so that it cannot move.
[0063] According to the embodiment described above, the lighting fixture 55, which is an interior component, is held by the holder 56 from the second housing 11R side (right side). In addition, the electrical wiring 60 is held in the wiring holding portion (first opening 56g and second opening 56e) of the holder 56. The lighting fixture 55 is held in the first housing 11L via the holder 56, and the second housing 11R is coupled to the first housing 11L with the electrical wiring 60 held therein. This improves the ease of assembling the lighting fixture 55 and the electrical wiring 60 to the main housing 11.
[0064] According to this embodiment, the magazine sensor 19e, which detects the remaining number of driving tools T in the magazine 19, is connected to the controller 23 via the electrical wiring 60. This prevents the driving tool 1 from being driven empty. The electrical wiring 60, which is wired between the tool body 10 and the magazine 19, is quickly and compactly wired via the wiring holding portion of the holder 56 and the wiring holding portion 62 of the magazine 19.
[0065] According to the embodiment, the wire holding portion of the holder 56 has a first opening 56g and a second opening 56e. The second opening 56e is narrower than the first opening 56g and is located closer to the magazine 19 than the first opening 56g. The electrical wire 60 is wired across the first opening 56g and the second opening 56e. A first portion 60a of the electrical wire 60 on the controller side passes through the first opening 56g. A second portion 60b of the electrical wire 60 on the magazine 19 side passes through the second opening 56e. As a result, the electrical wire 60 is wired and held compactly through the holder 56, which speeds up the assembly work of the electrical wire 60.
[0066] According to the embodiment, the magazine 19 is provided with a wire holding portion 62 for holding the electrical wires 60. The wire holding portion 62 on the magazine 19 side has a first opening 62a and a second opening 62b. The second opening 62b is wider than the first opening 62a and is located closer to the main body housing 11 than the first opening 62a. The electrical wires 60 are guided from the first opening 62a toward the second opening 62b. Therefore, the electrical wires 60 can be quickly and compactly routed from the magazine 19 side toward the main body housing 11 side.
[0067] According to the embodiment, the second opening 56e of the holder 56 is located closer to the second housing 11R (on the right side) than the first opening 56g, so that the electrical wiring 60 is routed three-dimensionally from the first housing 11L side to the second housing 11R side through the first opening 56g and the second opening 56e.
[0068] According to the embodiment, the driving tool 1 is a mechanical spring type driving tool that uses the biasing force of the compression spring 42 as a driving force, and is a tacker that drives U-shaped staples. The driving tool 1 is also a rechargeable tacker that is powered by a rechargeable battery pack 22. According to the embodiment, the rechargeable tacker improves the workability of assembling the lighting device 55 and wiring the electrical wiring 60 that prevents blank driving.
[0069] Various modifications can be made to the above-described embodiment. For example, although the lighting fixture 55 is exemplified as an interior part, the holder 56 can be applied to the case where other interior parts are attached to the inner surface of the first housing 11L or the second housing 11R.
[0070] Although the configuration has been exemplified in which the electrical wiring 60 of the magazine sensor 19e, which detects the remaining amount of driving tool T, is held in the wiring holding portion (second opening 56e) of the holder 56, it is also possible to hold, for example, the electrical wiring of the contact arm sensor 6 or the lighting device 55 in a holder that holds interior parts.
[0071] The driving tool T may be a U-shaped staple as illustrated, or may be a rod-shaped nail (pin nail).
[0072] The illustrated holder 56 can be applied to a mechanical spring type driving tool 1 that uses the biasing force of the compression spring 42 as the driving force, as well as an air spring type driving tool that uses the reaction force of an air spring generated by retracting a piston using an electric motor as the driving source as the driving force.
