Description

  The present invention relates to a magazine for storing a large number of driving tools in an air-driven driving tool called a pin tucker used for, for example, a flooring fixing work in a building site of a house.

In many cases, this type of driving tool includes a tool body with a piston that operates using compressed air as a drive source, and a driver guide that forms a driving path is provided at the tip of the tool body. The front end side of the magazine driving direction is connected to the driver guide. In the magazine, a plurality of thin driving tools (pins) are adhesively bonded in parallel to each other, and a connecting driving tool having a thin plate shape is stored.
The magazine has a magazine main body for storing the connected driving tool and a lid that is normally slidable, and the cover is provided with a pusher member that pushes the stored driving tool to the side of the passage. When the connection driving tool is set in the storage portion and the lid is closed, the stored connection driving tool is loaded in a state of being pushed toward the driving passage. For this reason, when one driving tool is driven out by the driving operation of the tool body, the connecting driving tool is pushed by the pusher member, so that it moves by one driving tool, and thereby the next driving tool is inserted into the driving passage. Is supplied.
Also, this type of magazine is provided with a so-called idle driving prevention mechanism. This blanking prevention mechanism prohibits the blanking operation on the tool body side when the number of the remaining hammering tools in the magazine is reduced, and prevents the blanking operation that causes damage to the workpiece. have. In addition, by operating the idle driving prevention mechanism, the user can recognize that the driving tool needs to be replenished.
In order to refill the driving tool, the lid is retracted in the opening direction to open the driving tool housing portion, the connecting driving tool to be refilled is set in the driving tool housing portion, and then the lid is advanced in the sliding direction and closed. In this case, the replenished connecting driving tool is loaded in a state of being pushed in the feeding direction by the pusher member.

However, in the above-described conventional magazine, when the head side on the leading end side in the feeding direction of the replenished connecting driving tool is warped in the lifting direction from the set surface of the magazine body, if the lid is closed as it is, this replenished connecting The driving tool is pushed in the feed direction by the pusher member, and the tip head portion (lifting portion) is caught by the driver guide wall portion without passing through the entrance (driving tool supply port) to the driving path, and the lid is closed. It becomes impossible. For this reason, there is a problem that the user needs to close the lid again while correcting the posture (lifting) of the connected driving tool that has been reopened and replenished.
The longer the stored connected driving tool is lifted from the set surface, the easier it is to generate. For example, in particular, a long driving tool having a length of 50 mm or more tends to have a large float and easily cause the above problem.
The present invention provides a magazine that is a long driving tool (a connecting driving tool), and can be smoothly closed even when a lift from the set surface occurs, for example, at the head in the feed direction. For the purpose.

Said subject is solved by each following invention.
A first invention is a magazine for supplying driving tools one by one into a driving path of a driver guide provided in a tool body, and driving for loading a connecting driving tool in which a number of driving tools are connected in parallel. A magazine body having a tool storage portion, and a slide lid provided on the magazine main body so as to be slidable to open and close the driving tool storage portion, the tip of the magazine body being coupled to a driver guide, A floating correction unit that is connected to the driving passage through the driving tool supply port and corrects the rising from the set surface of the driving tool receiving portion of the connecting driving tool above the driving tool supply port in the plate thickness direction of the connecting driving tool. Is a magazine with
According to the first invention , when setting the connecting driving tool in the driving tool receiving portion of the magazine body, the leading end in the feed direction is set in a state where the lifting from the set surface is regulated (corrected) by the lifting correction portion. Therefore, the slide lid can be smoothly closed thereafter.
A second invention is the magazine according to the first invention, wherein the magazine is provided with a correction part that rises from the center in the longitudinal direction of the longest driving tool that can be stored in the driving tool storage part.
According to the second aspect of the present invention, it is possible to efficiently control the lifting of a long driving tool that tends to be lifted from the set surface.
A third aspect of the invention is the magazine according to the second aspect of the present invention, wherein the floating correction part is provided integrally with the side part of the driver guide so as to protrude toward the rear side in the driving tool feeding direction.
According to the third aspect of the present invention , it is possible to achieve the strength of the lift correction part and the prevention of the position shift with a simple configuration.

Next, an embodiment of the present invention will be described with reference to FIGS. FIG.1 and FIG.2 has shown the driving tool 1 provided with the magazine 20 which concerns on this embodiment demonstrated below. In the embodiment described below, as an example of the driving tool 1, a so-called finishing nailing machine (so-called pin tacker) using compressed air as a drive source is illustrated. The present invention is characterized by the magazine 20, and the tool body 2 may be the same as the conventional configuration, and no particular changes are required in the embodiments described below. Therefore, the tool body 2 will be briefly described.
The tool body 2 includes a piston that reciprocates with compressed air. A handle portion 3 is provided so as to protrude sideways from the side of the tool body 2. A connection port 3 a for connecting an air hose for supplying compressed air is provided at the tip of the handle portion 3. The supplied compressed air is accumulated in the handle portion 3.
A trigger-type switch lever 4 is provided at the base of the handle portion 3. When the switch lever 4 is pulled with a fingertip, compressed air is supplied to the tool body 2 and the piston moves downward. A driver for hitting the driving tool is attached to the center of the lower surface of the piston.
From the lower part of the tool main body 2, the driver guide 10 is provided in a state extending downward. When the driver moves down the driving passage 10a in the driver guide 10, one driving tool n is driven out from the lower end portion (injection port 10b) of the driver guide 10.
The driver guide 10 includes a fixed plate 11 and an auxiliary plate 12 fixed to the tool main body 2 side, and a first movable plate 13 and a second movable plate 14 supported so as to be vertically displaceable within a certain range with respect to the fixed plate 11. It has. The fixed plate 11 and the auxiliary plate 12 are fixed in parallel to each other at a constant interval in the plate thickness direction. The fixed plate 11 extends longer than the auxiliary plate 12. The upper side of the second movable plate 14 is supported between the fixed plate 11 and the auxiliary plate 12 so as to be movable up and down without rattling in the plate thickness direction. The first movable plate 13 is fixed in a state of being superimposed on the lower side of the second movable plate 14. For this reason, the first movable plate 13 moves up and down integrally with the second movable plate 14. One continuous driving passage 10 a is formed between the second movable plate 14 and the auxiliary plate 12 and between the second movable plate 14 and the first movable plate 13. The lower end of this driving passage 10a becomes the injection port 10b.

The first and second movable plates 13 and 14 supported integrally with the tool main body 2 so as to be movable up and down are linked to the switch lever 4 via a lever (not shown). When the user presses the driving tool 1 against the workpiece and the first and second movable plates 13 and 14 move up relatively, the pulling operation of the switch lever 4 becomes effective and the driving operation is performed. The When the driving tool 1 is not pressed against the workpiece, and therefore the first and second movable plates 13 and 14 are not moved up relative to the fixed plate 11, the pulling operation of the switch lever 4 is invalid. The driving operation is not performed. Therefore, the first and second movable plates 13 and 14 have a function of forming the driving passage 10a therebetween and a function of preventing an erroneous operation of switching between valid and invalid for the pulling operation of the switch lever 4.
One driving tool is supplied from the magazine 20 to the driving passage 10a of the driver guide 10 one by one. A front end portion (left end portion in FIG. 1) of the magazine 20 in the driving tool feeding direction is supported by the driver guide 10. On the other hand, the rear end side (right end side in FIG. 1) of the magazine 2 in the driving tool feeding direction is supported near the front end portion of the handle portion 3 via the bracket portion 20a.

The details of the magazine 20 according to this embodiment are shown alone in FIG. The magazine 20 includes a magazine main body 21 having a substantially flat plate shape and a slide door 22 for opening and closing the magazine main body 21. The front end side of the magazine main body 21 in the driving tool feeding direction is fixed to the back surface (the side opposite to the driving passage 10a) of the fixing plate 11 of the driver guide 10. On the inner surface side (upper surface side in FIG. 4) of the magazine main body 21, a driving tool storage portion 21 a for storing a number of driving tools n to n is provided. The driving tool accommodating portion 21a can be loaded with a driving tool connecting plate N having a single flat plate shape by bonding a large number of elongated driving tools n to n in parallel to each other. In the case of this embodiment, about the length of each driving tool n, seven types of driving tool connection plates N of, for example, 50 mm, 45 mm, 40 mm, 35 mm, 30 mm, 25 mm, and 18 mm can be loaded. In this specification, the driving tool feeding direction refers to the direction in which the driving tool connecting plate N (the driving tools n to n) is sent toward the driving passage 10a. Accordingly, in FIGS. 2 to 4, the driving tool connecting plate N (the driving tools n to n) is sent from right to left.
A pusher plate 31 that pushes the loaded driving tool connecting plate N in the driving tool feeding direction is provided on a set surface 21d (a bottom surface that receives the driving tool connecting plate) of the driving tool receiving portion 21a. As shown in FIG. 6, the pusher plate 31 is supported so as to be movable in the driving tool feeding direction by inserting a guide bar 32 into a cylindrical support portion 31a provided on the lower surface side. As shown in FIG. 4, the guide bar 32 is provided in a state of being stretched from the front end to the rear end of the magazine body 21 in the driving tool feeding direction. The pusher plate 31 is biased by the compression spring 24 in the driving tool feeding direction. When the driving tool connecting plate N is pushed in the driving tool feeding direction by the pusher plate 31, the driving tools n are fed into the driving passage 10a of the driver guide 10 one by one. However, the urging force by the compression spring 24 acts when the slide door 22 is closed, and does not act when the slide door 22 is opened. For this reason, in a state where the slide door 22 is opened, the driving tool connecting plate N can be easily loaded into and removed from the driving tool housing portion 21a. When the sliding door 22 is closed, the urging force of the compression spring 24 acts on the pusher plate 31, thereby pushing the driving tool connecting plate N in the driving tool feeding direction.
The front end side of the driving tool receiving portion 21a in the driving tool feeding direction communicates with the driving path 10a of the driver guide 10.
A driving tool guide groove 21c for restricting the position of the stored driving tool connecting plate N in the driving tool length direction is provided along the driving tool feeding direction on the lower end side in FIG. ing. By making the leading end side of the driving tool connecting plate N enter the driving tool guide groove 21c, the driving tool connecting plate N is positioned at a reference position in the driving tool length direction. Regardless of the length of the loaded driving tool connecting plate N, the tip thereof is always stored in the reference position that is abutted against the bottom of the driving tool guide groove 21c. For this reason, the position of the head differs depending on the length of the stored driving tool connecting plate N.

A slide door 22 is supported on the magazine main body 21 so as to be slidable along the driving tool feeding direction. As shown in FIG. 6, a pair of guide rail portions 21b, 21b having a U-shaped cross section are provided on the left and right sides of the magazine main body 21 in the feeding tool feeding direction so as to face each other. On the other hand, guide edge portions 22a and 22a are provided on the left and right side portions of the slide door 22 in the driving tool feeding direction. The guide edge portions 22a and 22a are respectively held in the guide rail portion 21b, and the slide door 22 is supported so as to be able to advance (close operation) and retreat (open operation) along the driving tool feeding direction.
The sliding door 22 is closed when it is slid leftward in FIGS. 2 to 4 and is opened when it is slid rightward. 2 and 4 show a state where the slide door 22 is slightly opened, and FIG. 3 shows a state where the slide door 22 is closed. When the slide door 22 is opened, the driving tool accommodating portion 21a is opened, and the driving tool connecting plate N can be loaded. The driving operation of the tool body 2 is performed with the slide door 22 closed.
A guide member 25 is provided on the inner surface of the slide door 22 for regulating the posture of the driving tool connecting plate N (driving tools n to n) housed in the driving tool housing portion 21a. The guide member 25 has an elongated flat plate shape. In this embodiment, the seven guide members 25 to 25 correspond to the seven types of driving tools n with respect to the length that can be loaded. Is provided.
Each guide member 25 has a driving tool feeding direction (leftward in FIGS. 2 to 4), an anti-driving tool feeding direction (rightward in FIGS. 2 to 4), and a driving tool connecting plate with respect to the inner surface of the slide door 22, respectively. N is supported so as to be displaceable in the plate thickness direction (vertical direction in FIG. 4).
The front side of each guide member 25 in the driving tool feeding direction is supported by the slide door 22 via the guide holder 28, and the rear side is directly supported by a support wall portion 29 provided on the inner surface of the slide door 22. Independently of each other, they are supported so as to be movable along the driving tool feeding direction and displaceable in the vertical direction (direction approaching and separating from the driving tool connecting plate N).

A leaf spring 27 is interposed between the guide holder 28 and the vicinity of the tip of each guide member 25. The leaf spring 27 biases each guide member 25 mainly in a direction in which its tip end side is elastically pressed against the driving tool connecting plate N, or in a direction in which the guide member 25 enters a relief groove provided on the set surface 21d of the driving tool receiving portion 21a. (Hereinafter simply referred to as a direction in contact with the set surface 21d). Of the seven guide members 25 to 25, the five guide members 25 to 25 pressed against the driving tool connecting plate N are lifted from the set surface 21 d of the driving tool housing portion 21 a of the driving tool connecting plate N ( In FIG. 4, each of the driving tool connecting plates N is driven by one guide member 25 that is displaced in the length direction of the driving tool connecting plate N and is in contact with the set surface 21d. The axial displacement of the tool n (displacement upward in FIG. 3) is restricted.
The number of guide members 25 that are pressed against the driving tool connecting plate N and the number of guide members 25 that are released in the length direction and are not pressed against the driving tool connecting plate N are determined by the length of the loaded driving tool connecting plate N (the driving tool). n length). In the present embodiment, as shown in FIGS. 3 and 6, of the seven guide members 25 to 25, the upper two guide members 25 and 25 are released in the length direction and pressed against the driving tool connecting plate N. Since the lower five guide members 25 to 25 are pressed against the driving tool connecting plate N, the driving tool housing portion 21a is loaded with the driving tool connecting plate N having a length of 45 mm. It is shown in the state.
A first spring 26 is interposed between the rear end portion of each guide member 25 and the inner surface rear portion of the slide door 22. In the present embodiment, a compression coil spring is used for the first spring 26. Each guide member 25 is urged forward by the first spring 26 in the driving tool feeding direction.
The guide holder 28 is supported so as to be movable within a certain range in the driving tool feeding direction with respect to the slide door 22. A second spring 35 is interposed between the guide holder 28 and the vicinity of the central portion in the longitudinal direction of each guide member 25. Each second spring 35 is a compression coil spring. By the second spring 35, the guide holder 28 is urged to the front side in the driving tool feeding direction with respect to each guide member 25. The total biasing force of all the second springs 35 to 35 with respect to the guide holder 28 is set to be weaker than the total biasing force of the first spring 26 that biases the guide members 25 to 25 respectively. For this reason, the guide holder 28 is supported so as to be displaceable rearward in the driving tool feeding direction with respect to the guide members 25 to 25 against the total biasing force of the second springs 35 to 35.
As shown in FIG. 5, an upper insertion window portion 28a and a lower insertion window portion 28b are provided on the front side of the guide holder 28 in the driving tool feeding direction. A restriction wall portion 28c is provided between the upper and lower two insertion window portions 28a and 28b.

On the other hand, two restricting arm portions 25a and 25b having different lengths are provided at the leading end portion of each guide member 25 in the driving tool feeding direction. In FIG. 3, the upper restriction arm portion 25a is shorter than the lower restriction arm portion 25b. The upper restriction arm portion 25a is inserted through the upper insertion window portion 28a of the guide holder 28, and the lower restriction arm portion 25b is inserted through the lower insertion window portion 28b. As shown in the drawing, the lower restricting arm portion 25b extends substantially straight to the front side in the driving tool feeding direction, but the tip end portion of the upper restricting arm portion 25a is bent downward in an L shape. Hereinafter, a portion of the upper restriction arm portion 25a that extends straight forward in the driving tool feeding direction is referred to as a lower displacement portion 25aa, and a portion that is a tip portion of the lower displacement portion 25aa and is bent downward is referred to as an upper portion. It is called the displacement part 25ab.
As shown in FIG. 5, when the slide door 22 is opened with respect to the magazine body 21, the guide holder 28 is displaced to the front side in the driving tool feeding direction with respect to the guide member 25 by the second spring 35. When the guide holder 28 is displaced to the front side in the driving tool feeding direction with respect to the guide member 25 by the second spring 35, the upper displacement portion 25ab of the guide member 25 gets on the restriction wall portion 28c of the guide holder 28. In this state, the front portion of the guide member 25 is displaced to the upper non-regulating position. When the front portion of the guide member 25 is displaced to the upper non-regulating position, the guide member 25 is lifted from the driving tool connecting plate N. In this state, the guide holder 28 is positioned on the front side in the driving tool feeding direction with respect to the front end portion of the slide door 22 and is positioned on the front side in the driving tool feeding direction with respect to the guide members 25, and (The lower regulating arm portion 25b) is held in a state where it is accommodated in the insertion window portion 28b (a state in which the lower regulating arm portion 25b does not protrude forward).
Further, the guide holder 28 is positioned in front of the pusher plate 31 in the driving tool feeding direction.
From the above, when closing the slide door 22, the guide member 25 located at the non-restricted position firstly interferes with the rear end of the driving tool connecting plate N at the front lower corner portion of the guide holder 28 in the driving tool feeding direction. Does not interfere.

In contrast, when the slide door 22 is closed with respect to the magazine body 21 as shown in FIGS. 7 and 8, the guide holder 28 comes into contact with the back surface of the fixed plate 11 constituting the driver guide 10 and is relatively moved. It is pushed backward in the driving tool feed direction. Since the total biasing force of the first springs 26 to 26 is set to be larger than the total biasing force of the second springs 35 to 35, the guide holder 28 resists the total biasing force of the second springs 35 to 35. 25 is displaced rearward relative to the driving tool feed direction. Then, the upper displacement portion 25ab of the guide member 25 is detached from the restriction wall portion 28c, and the lower displacement portion 25aa is put on the restriction wall portion 28c (FIG. 7) or slightly lifted (FIG. 8). . In this state, the guide member 25 is displaced to the lower restriction position. When the guide member 25 is displaced to the lower restriction position, the guide member 25 is in contact with the set surface 21d of the driving tool accommodating portion 21a (FIG. 7) or the guide member 25 is in contact with the driving tool connecting plate N (FIG. 8). )
The guide member 25 shown in FIG. 7 is a guide member that is located at a position away from the head of the driving tool connecting plate N in the driving tool length direction. For this reason, the guide member 25 shown in FIG. 7 is in a state of not contacting the driving tool connecting plate N but contacting the set surface 21d of the driving tool housing portion 21a. On the other hand, the guide member 25 shown in FIG. 8 shows a guide member positioned within the length range of the driving tool connecting plate N in the driving tool length direction. For this reason, the guide member 25 shown in FIG. 8 is in a state of being in contact with the driving tool connecting plate N.

When the slide door 22 is closed in this way, the guide holder 28 does not protrude from the front end portion of the slide door 22. In this state, the lower restricting arm portion 25b of the guide member 25 is protruded from the lower insertion window portion 28b of the guide holder 28 to the front side in the driving tool feeding direction, and the tip portion 25ba is the second to be driven next. To the position where the displacement of the driving tool n2 is restricted. The first driving tool n1 on the front side of the second driving tool n2 is located in the driving path 10a.
The regulation arm portion 25b on the lower side of each guide member 25 is not provided with a conventional inclined guide surface. In the present embodiment, normal R surfaces are merely chamfered at the upper corner portion and the lower corner portion in the width direction (vertical direction) of the restriction arm portion 25b. Conventionally, when closing the slide door, the guide member can be smoothly driven by avoiding catching between the lower corner portion of the regulating arm portion 25b and the rear end portion of the driving tool connecting plate N. However, in this embodiment, when the slide door 22 is closed, the guide members 25 are displaced to the non-regulatory position. Therefore, the inclined guide surface is not necessary.
In the present embodiment, as shown in FIG. 5, it is a front end corner portion of the guide holder 28 in the driving tool feeding direction, and is hooked to the lower corner portion of the driving tool connecting plate N side with respect to the rear end portion of the driving tool connecting plate N. A large R surface 28d is formed as an avoidance portion. By this R surface 28d, the guide holder 28 is prevented from being caught by the rear end portion of the driving tool connecting plate N when the slide door 22 is closed. Further, between the lower surface of the guide holder 28 and the set surface 21d of the driving tool accommodating portion 21a, a necessary and sufficient width for the thickness of the driving tool connecting plate N to be loaded (the thickness of the driving tool n) is sufficient. A gap is set.
As described above, in the present embodiment, the driving tool connecting plate N is provided on the lower regulating arm portion 25b of the guide member 25 that needs to reliably control the displacement of the second driving tool n2 mainly. For a guide holder 28 that does not have a hook avoidance portion (inclined guide surface, large R surface, etc.) with respect to the rear end portion and does not directly have such a positional deviation restriction function, a sufficiently large hook avoidance portion (R surface 28d) is provided, Engagement with the rear end portion of the driving tool connecting plate N when the sliding door is closed is reliably avoided.

Next, as shown in FIG. 9, a driving tool supply port 11 c is provided on the back surface of the fixed plate 11 to communicate the driving tool storage portion 21 a on the magazine 20 side with the driving passage 10 a on the driver guide 10 side. The driving tool n (the driving tool connecting plate N) is supplied from the magazine 20 to the driving path 10a through the driving tool supply port 11c. As shown in FIGS. 7 and 8, the driving tool supply port 11 c has relief passages 11 d to 11 d for allowing the lower side restricting arm portion 25 b of each guide member 25 to enter the front of the driving path 10 a. The supply port 11c is provided in a state where the supply port 11c is cut to the upper side in the figure at a constant height. As described above, the seven guide members 25 to 25 are provided on the slide door 22, and the escape passages 11 d to 11 d are provided corresponding to the seven guide members 25 to 25 along the longitudinal direction of the driving tool n. .
As shown in FIG. 9, on the head side (right end side in FIG. 9) of the driving tool n, between the second escape passage 11d and the third escape passage 11d from the right side of the drawing, 11 is provided with a lifting correction portion 40 for restricting lifting of the stored driving tool connecting plate N from the set surface 21d. A guide inclined surface 40a for guiding the distal end portion of the driving tool connecting plate N to the set surface 21d side of the driving tool accommodating portion 21a is provided on the distal end side of the lifting correction portion 40.
With respect to the longitudinal direction of the driving tool n, by providing the lifting correction unit 40 at the above position, the driving tool n (the driving connection plate N) having the longest length that can be loaded into the magazine 20 by the lifting correction unit 40. Further, the lifting of the head side from the center in the longitudinal direction is reliably and efficiently regulated.
Further, as shown in FIG. 10, the lifting correction portion 40 is integrally provided in a state of protruding from the back surface of the fixed plate 11 to the rear side in the driving tool feeding direction. The distance between the lift correction unit 40 and the set surface 21d of the driving tool storage unit 21a of the magazine 20 is set to be approximately the same as the height of the driving tool supply port 11c.
Corresponding to the lift correction part 40, an escape recess 28 e for accommodating the lift correction part 40 is provided on the front end surface of the guide holder 28 in the feeding direction. When the floating correction portion 40 is inserted into the escape recess 28e, the guide holder 28 is brought into contact with the back surface of the fixed plate 11 without any gap, and thus the slide door 22 can be completely closed. Yes.

According to the magazine 20 of the present embodiment configured as described above, the lifting correction unit 40 lifts the driving tool n from the set surface 21d of the driving tool housing part 21a mainly on the head side of the driving tool supply port 11c. Regulated just before.
Here, since the remaining number of driving tool connecting plates N1 is reduced as shown in FIG. 10, when a new driving tool connecting plate N2 is replenished, the feeding direction front end side of the replenished driving tool connecting plate N2 is illustrated. In some cases, it may be warped in the direction of lifting from the set surface 21d of the driving tool storage portion 21a. In this case, if the slide door 22 is closed as it is, the lifted portion overlaps the rear portion of the remaining driving tool connecting plate N1, and as a result, the slide door 22 cannot be closed. In this case, it is necessary to open the slide door 22 again and close the slide door 22 slowly while holding the tip end side of the replenished driving tool connecting plate N2 with the fingertips so as not to overlap.
Further, when the remaining driving tool connecting plates N1 are replenished with a new driving tool connecting plate N2 when the remaining number is about two or three, the head side on the leading side in the feed direction is warped mainly in the direction of lifting. Since the tip floating portion does not smoothly enter the driving tool supply port 11c as it is, it is sandwiched between the slide door 22 and the fixed plate 11, and in this case, the slide door 22 is smoothly closed. It becomes impossible to do.
On the other hand, according to the lift correction unit 40 of the present embodiment, when the tip end side in the feeding direction of the replenished driving tool connecting plate N2 is lifted from the set surface 21d of the driving tool storage portion 21a, the tip side is Since the movement in the driving tool feeding direction is restricted by coming into contact with the lifting correction part 40, it is prevented from overlapping with the rear part of the remaining driving tool connecting plate N1. The tip lifted portion of the driving tool connecting plate N2 that is avoided from being overlapped is pressed against the set surface 21d by the R surface 28d of the guide holder 28, and the lift (warpage) is corrected. Can be closed.

Further, even when the remaining number of driving tool connecting plates N1 is about two or three and the replenished driving tool connecting plates N2 do not overlap, the tip lifted portion of the replenished driving tool connecting plate N2 does not overlap. Since it comes into contact with the lifting correction portion 40 and is then pressed against the set surface 21d by the R surface 28d of the guide holder 28, the lifting portion is not sandwiched between the fixed plate 11 and the guide holder 28. Thus, the sliding door 22 can be closed smoothly. The distal end portion of the driving tool connecting plate N2 pressed against the set surface 21d of the driving tool receiving portion 21a is pushed by the pusher member 31 to enter the lower side of the lifting correction portion 40, and after the remaining driving tool connecting device N1. It abuts (continues) the end.
Furthermore, according to the illustrated embodiment, with respect to the position in the length direction of the driving tool n, the second relief recess 11d and the third relief recess 11d on the head side (from the upper side in FIG. 9) A floating correction unit 40 is provided therebetween. This position is a position closer to the head than the center in the length direction of the driving tool n having the longest length (50 mm) that can be loaded in the magazine 20. In the case of a long driving tool connecting plate N having a length of the driving tool n of, for example, 45 mm or 50 mm, the head side is particularly likely to warp in the lifting direction. As a result of the lifting of the driving tool connecting plate N being restricted by the driving tool guide groove portion 21c, the longer the driving tool, the more easily the head side of the driving tool is connected to the set surface 21d. From this point of view, for the long driving tool n having a length of 45 mm or 50 mm, the floating correction unit 40 is disposed on the head side, thereby reliably and efficiently regulating the lifting of the loaded driving tool connecting plate N mainly on the head side. As a result, it is possible to ensure a good closing operability of the slide door 22.

Various modifications can be made to the embodiment described above. For example, with respect to the position in the length direction of the driving tool n, the configuration in which the lifting correction unit 40 is provided in one place on the head side is illustrated, but the configuration in which the lifting correction unit is provided in two or more locations may be employed. Therefore, it is good also as a structure which protrudes and provides the correction | amendment correction | amendment part along the feed direction back like a ridge along between two adjacent escape passages 11d and 11d.
Further, the guide member 25 is shifted in the thickness direction of the driving tool connecting plate N by moving the guide holder 28 back and forth in the feed direction, so that the driving tool connecting plate at the tip of the guide member 25 when the slide door 22 is closed. Although a configuration in which interference with the rear end portion of N is avoided and the position of the second driving tool n2 is regulated by the distal end portion of the guide member 25 in the closed state of the slide door 22 is illustrated, the magazine does not have such a configuration. The same effect can be obtained by applying the lifting correction unit 40.
Further, although the compressed air drive type nailing machine is exemplified as the driving tool, the present invention can be similarly applied to other types of driving tool magazines such as a pin tacker (electric tacker) using an electric motor as a driving source.
