FIG. 1 is a perspective view of a stapler according to the present embodiment, FIGS. 2A and 2B are a side view and a rear view, respectively, and FIG. 3 is a cross-sectional view showing a schematic configuration thereof. In this stapler, a magazine portion 3 that accommodates a large number of staples and a staple (not shown) that is accommodated in the magazine portion 3 are ejected toward a binding sheet on a support shaft 2 at the rear end portion of the base 1. A handle portion 5 having a driver plate 4 is rotatably supported.

  A clincher groove 6 for bending the leg portion of the staple punched out from the magazine portion 3 is formed at the distal end portion of the base 1, and a support wall 7 is formed upright at the base portion. Also, a remover 8 is formed at the rear end of the base 1 so as to protrude from a thin plate shape with a thin tip used for removing staples on which sheets to be bound are bound.

  The magazine section 3 is loaded with a plurality of staples, and a punching section 10 for punching the leading staple is formed at the leading end. A pusher 11 is engaged with the rear end of the loaded staple, and the pusher 11 is urged by a spring 12 so as to always move the staple to the firing unit 10 side.

  The magazine portion 3 is urged by a leaf spring 13 provided at the base portion of the base 1 so that a constant interval is always maintained with respect to the base 1.

  The handle portion 5 is formed in a U shape whose cross section is open downward, and a driver plate 4 is formed at the inner tip. A staple presser 15 is integrally provided at the lower portion of the handle portion 5. The base of the staple retainer 15 is engaged with the support shaft 2, the tip is slidably held in the height direction of the driver plate 4, and the magazine 3 side is attached by a spring plate 16 attached to the upper bottom of the handle 5. It is urged to rotate.

  With the above configuration, the staple paper P is sandwiched between the base 1 and the magazine section 3 loaded with a plurality of staples, and the handle section 5 is pressed against the magazine section 3 side. The staples can be ejected from the launching portion 10 to penetrate the paper to be bound, and the leg portions of the penetrated staples can be bent by the clincher grooves 6 of the base 1 and bound.

  Resin covers 17 and 18 made of synthetic resin are fixed to the handle portion 5 and the tip of the base 1. A recess portion 19 is formed in the resin cover 17 of the handle portion 5.

  The magazine portion 3 is disposed inside the support wall 7 of the base 1 and the handle portion 5 is disposed outside the support wall 7, and is rotatably supported by a common support shaft 2. Both ends of the support shaft 2 are exposed on both side surfaces of the handle portion 5.

  By the way, the above-mentioned stapler is covered with a protective cover 14 made of synthetic resin on the upper surface of the base portion of the handle portion 5. This protective cover 14 is softer than metal.

  The protective cover 14 is formed in a U-shaped cross section downward from an upper surface portion 14a and both side portions 14b. The distance between the side portions 14b is formed to be substantially the same as the width of the handle portion 5. That is, it is formed so as to be fitted to the base portion of the handle portion 5, the upper surface portion 14a of the protective cover 14 covers the upper surface of the handle portion 5, the side portions 14b cover the side surfaces of the handle portion 5, and the upper end of the upper surface portion 14a is It is flat. 4A and 4B, a protrusion 20 is formed on the back surface of the upper surface portion 14a of the protective cover 14, and a locking protrusion 21 is formed on the inner surface of both side portions 14b. Then, the protective cover 14 locks the locking protrusions 21 of the both side portions 14b with respect to the handle portion 5 in locking holes 22 formed on the side surfaces of the handle portion 5, and the protrusion 20 on the upper surface of the handle portion 5. It is attached by penetrating through the formed attachment hole 23.

  Both side portions 14 b of the protective cover 14 cover both ends of the support shaft 2 of the base 1.

  As well shown in FIG. 1, a recess 24 is formed in the upper surface portion 14 a of the protective cover 14. The recess 24 has a shape that fits the thumb 30 when the stapler is reversed as shown in FIG. Further, the recess 24 is formed on the right side and the left side of the upper surface of the protective cover 14. However, as shown in FIG. 7, the recess 24 may be formed at the center of the protective cover 14. Moreover, you may make it form the slip prevention 24a in the said hollow part 24 or its vicinity. The anti-slip material may be uneven or may not be slippery.

  Next, as shown in FIGS. 4A and 6A and 6B, a storage groove 25 is formed on the upper surface of the handle portion 5 on the back side of the base end portion of the hollow portion 24. Yes. The storage groove 25 is opened in the extending direction of the handle portion 5, and when the handle portion 5 is opened and deployed so as to be straight with respect to the base 1, the remover 8 protruding from the base portion of the base 1 is removed. It is formed so that it can be stored.

Since the above-described protective cover 14 is attached to the base portion of the handle portion 5 of the stapler, the following operational effects can be obtained.
(1) As shown in FIG. 5, when the stapler is used while being held upside down, the protective cover 14 having the recessed portion 24 is attached to the upper surface portion 14a of the portion that contacts the thumb 30, so that it is less slippery than metal. It has a good feel and is easy to hold. Further, since both side portions 14b of the protective cover 14 cover the end portion of the support shaft 2 of the base 1, there is no pain even if a force is applied during the spelling operation, so that the operation feeling is good and the workability is also good.
(2) A recess 24 is formed in the protective cover 14. Normally, when the stapler is held upside down, the thumb 30 hits the corner of the base of the handle portion 5, and this portion is shaped to fit the thumb 30. As described above, since the recessed portion 24 is formed in the portion that becomes the fulcrum when the thumb 30 is applied and the reverse holding operation is performed, the spelling operation can be stably performed.
(3) If the said recessed part 24 is formed in the right side and the left side, it can respond even if it is right-handed or left-handed. Of course, even if the depression 24 is formed in the center of the protective cover 14, it can be right-handed and left-handed.
(4) Since the protective cover 14 is formed in a U-shaped cross section and the support shaft 2 of the base 1 is covered by the both side portions 14b, not only is the safety as described above, but the support shaft 2 is external. The overall appearance is improved because it is not exposed.
(5) Since the side surface portion of the handle portion 5 and both side portions 14b of the protective cover 14 and the bottom surface portion of the handle portion 5 and the upper portion of the protective cover 14 are engaged with each other, a separate pin or the like It can be mounted without the need for engaging parts.
(6) If the recess 24 is formed with a non-slip, the thumb is difficult to slip. Therefore, the thumb is hard to come off from the fit shape part even when working with the stapler reversed. Good operability and operability.
(7) The tacking operation for driving the staple into the object is performed by opening the handle portion 5 so as to be straight with respect to the base 1, but it protrudes from the base portion of the base 1 during expansion. Since the remover 8 that has reached the upper surface of the base portion of the handle portion 5 is stored in the storage groove 25 of the protective cover 14, a finger is pinched between the handle portion 5 and the remover 8, and the player is injured by hitting it. It is possible to ensure safety during operation.
(8) A circular portion is formed in a portion corresponding to the support shaft 2 of the both side portions 14b. Since this circular portion is reminiscent of the center of rotation, a natural appearance can be obtained.
(9) Since the protective cover 14 is provided separately from the resin cover 17 at the tip of the handle portion, the cost can be reduced by covering only the necessary portions.

  In addition, the shape of the site | part which hangs a thumb should just be effective as a finger hook, and does not necessarily need to be a hollow. It may be formed in a protruding shape. For example, the upper surface portion 14a in FIG. 1 has a protruding shape between the left and right hollow portions 24, and constitutes a protruding portion, but when held in reverse, the holdability when the thumb is put on the protruding portion 14a is improved. Well, the thumb is hard to come off even when working with force when using the stapler upside down, so that the workability and operability are good and the spelling operation can be performed stably.

  Similarly, FIG. 8 shows a case in which a protrusion 26 having an elliptical shape around the center and a gently raised center is formed at the center of the protective cover 14 at the base of the handle portion 5. The thumb is hard to come off when it is held upside down, which is effective as a finger hook. If the projecting portion 26 is configured to be elastic, it does not hurt very much because there is elasticity even if the grip when the stapler is reversely held is strengthened.

  There is no particular limitation on the position or shape of the protrusion. As in the case shown in FIG. 1, the protective cover 14 may be formed on the left and right sides, or may be rectangular as a whole. Similarly, the shape of the dent portion 24 is not limited as long as it fits to such an extent that the thumb does not move during work, and may have an oval shape like the dent portion 24 shown in FIG. 9.

  Further, a resin cover and a protective cover at the tip of the handle portion may be provided integrally. For example, FIG. 10 shows an example in which the resin cover 17 and the protective cover 4 are integrally provided via the connecting cover 27. The resin cover 17 and the protective cover 14 at the tip are formed with recessed portions 19 and 24, respectively. . FIG. 11 also shows an example in which the resin cover 17 and the protective cover 14 are integrally provided via a connection cover 27. The connection cover 27 covers the outer surface of the handle portion 5, and the recess 19 is formed in the resin cover 17 at the tip. A protrusion 26 is formed on the upper surface of the protective cover 14, and its upper end is formed flat. A small protrusion 28 for preventing slipping is formed inside the recess 19.

  As described above, according to the configuration in which the resin cover 17 at the distal end of the handle portion and the protective cover 14 are provided integrally, a sense of unity and unity can be expressed in the overall design.
