Description

The present invention relates to a stapler. More specifically, the present invention relates to a stapler capable of preventing the stapler from being idle by sensuously notifying the operator that the remaining amount of staples filled in the stapler has decreased.

A stapler is widely used as an instrument for easily binding various types of paper materials. The basic structure of this stapler is an integrated handle, base, magazine that is filled with a large number of staples loosely joined, and a driver that has protrusions that eject the staples that are filled in the magazine. Each of them has a structure in which the stapler is rotatably attached to the rear end portion.

By the way, in the conventional stapler, there is no means for notifying the operator of this state when all the staples filled in the magazine portion are used up. Therefore, when the operator tries to launch the staples by operating the stapler, he / she is first noticed that there is no staple to be launched in a so-called blank shot state.

The work by the stapler involves the work of aligning the paper documents to be bound as the preparatory work, and it is expected that the worker will concentrate the work considerably on the work. If the stapler is left blank after the work is performed, the stapler is temporarily suspended for the stapler replenishment work, and then the paper documents are aligned again to remove the stapler. Since it is necessary to operate it, the work becomes inefficient, and the worker feels psychologically discouraged and laborious because it is after the work with a focus on consciousness.

In response to the above problems, for example, in Patent Document 1, the staple located at the end of a series of loosely joined staples is colored in a color different from that of other staples to give a difference in appearance. The staples are disclosed. According to Patent Document 1, the worker can easily determine whether or not the stamped staple is the last one by checking the color of the stamped staple. ..

Further, in Patent Document 2, the remaining amount of staples is displayed by an LED, and when the remaining amount of staples reaches a predetermined amount, the lighting pattern of the LED is changed, so that the remaining amount of staples is given to the operator. A stapler is disclosed that informs that the number of LEDs has decreased.

However, in the staples according to Patent Document 1, when the staples are replenished to the stapler, it is necessary to always arrange the colored staples at the end, which may complicate the replenishment work. In addition, the worker must always check the color of the staples that have been stamped out after working with the stapler. For example, when binding a large number of documents in an assembly line, the staples that have been stamped out are always stamped out. Having to confirm the above has hindered the efficiency of work.

Further, also in the stapler according to Patent Document 2, the operator must always pay attention to the LED display when performing the work, but as described above, when performing the work of binding a large number of documents, it is not always necessary. The operator does not work while looking at the vicinity of the hand where the stapler is operated, and there is a risk that the LED display may be overlooked. Further, in order to display the LED, a drive power supply and wiring are also required, and the stapler mechanism itself is complicated, which is not feasible.

The present invention was devised in view of the above points, and by sensuously notifying the operator that the remaining amount of staples filled in the stapler has decreased, the staples are struck blank. It is an object of the present invention to provide a stapler capable of preventing the above.

In order to achieve the above object, the stapler according to the present invention has a handle portion in which a through hole is formed at a predetermined position, an accommodating portion in which a concave groove for accommodating staples is formed, and a front end of the accommodating portion. The staples housed in the accommodating portion, including the outlet for punching the staples toward the binding paper, and the fitting recess formed in the same direction as the opening direction of the concave groove, are inserted into the outlet. A magazine portion having a pusher that presses toward the outlet, a base portion having a clincher that bends and forms a leg portion of the staple ejected from the outlet, and the staple accommodated in the accommodating portion toward the outlet. A driver portion having a piece to be punched out, a main body portion, a fitting convex portion that can be fitted into the fitting concave portion when the pusher is placed at a predetermined position on one end of the main body portion, and the other end of the main body portion. Provided with a staple remaining amount display mechanism having a protrusion that can partially protrude toward the through hole in a state where the fitting protrusion is fitted in the fitting recess.

Here, by providing the handle portion in which the through hole is formed at a predetermined position, it is possible to project a part of the protrusion portion of the staple remaining amount display mechanism from the through hole, as will be described later. Therefore, when the operator grips the handle portion and works, the remaining amount of staples can be sensuously sensed depending on the presence or absence of the protrusion portion.

Further, when the magazine portion has an accommodating portion in which a concave groove for accommodating the staple is formed, the staple can be filled in the concave groove.

Further, when a punching hole for punching the staples toward the binding paper is formed at the front end of the accommodating portion, the staples can be sequentially punched from the punching port toward the binding paper.

Further, when the magazine portion has a pusher that presses the staples housed in the accommodating portion toward the outlet, the staples accommodated in the accommodating portion can be sequentially sent out toward the outlet by the pusher.

Further, when the pusher includes a fitting recess formed with an opening in the same direction as the opening direction of the concave groove, as will be described later, when the remaining amount of staples becomes less than a predetermined amount, the remaining amount of staples remains. The fitting convex portion of the mechanism can be fitted into the fitting concave portion, and the protrusion can be projected from the handle portion by the reaction thereof.

Further, the main body, the fitting convex portion that can be fitted into the fitting concave portion when the pusher is at a predetermined position at one end of the main body portion, and the fitting convex portion that fits into the fitting concave portion at the other end of the main body portion. By providing a staple remaining amount display mechanism having a protrusion that can partially protrude toward the through hole in the fitted state, the fitting convex portion becomes the fitting concave portion when the remaining amount of staple becomes less than a predetermined value. Since the protrusion can be projected from the through hole of the handle portion by the reaction caused by being fitted to the operator, it is possible to intuitively notify the operator that the remaining amount of staples is low. ..

Further, the protrusion is always urged by the urging member in the substantially launching direction of the staple, and when the fitting convex portion is fitted into the fitting recess, the urging member resists the urging force. When it is configured to protrude from the through hole, the protrusion is urged by an urging member in a normal state where the remaining amount of staples is sufficient, so that the staple may be inadvertently projected from the through hole. Can be prevented.

On the other hand, when the remaining amount of staples becomes less than a predetermined value and the pusher moves to a predetermined position and the fitting convex portion is fitted into the fitting concave portion, a vertically upward force that opposes the urging force on the protruding portion is triggered. Can cause the protrusion to protrude from the through hole by the action of.

Further, when the last one staple accommodated in the accommodating portion is launched by the driver portion and the fitting convex portion is fitted into the fitting concave portion, when the remaining amount of the staple becomes zero. The fitting protrusion can be fitted into the fitting recess, and the protrusion can be projected from the through hole of the handle portion. That is, when the operator starts the next work, when the handle portion is gripped, the protrusion protruding from the through hole is perceived as a sense of discomfort, and it is possible to grasp that the staples in the accommodating portion have disappeared. It is possible to prevent the staples from being hit in the work.

A long hole is formed at the other end of the main body of the staple remaining amount display mechanism, and when the protrusion is slidably supported along the long hole, the movable range of the protrusion can be expanded. , When the fitting convex portion is fitted into the fitting concave portion, the movement of the protruding portion becomes smoother.

Further, when the substantially central portion of the main body portion of the staple remaining amount display mechanism in the longitudinal direction is pivotally supported at a predetermined position of the driver, the main body portion can be held more stably.

The stapler according to the present invention can prevent the staples from being idle by sensuously notifying the operator that the remaining amount of staples filled in the stapler is low. ..

It is an exploded perspective view of the stapler which concerns on embodiment to which this invention was applied. It is a completed perspective view of the stapler which concerns on embodiment to which this invention is applied. It is a partially broken side view of the stapler which concerns on embodiment to which this invention is applied, (a) is a plan view, and shows the state in which staples decrease in order of (b)-(f).

Hereinafter, embodiments of the present invention will be described with reference to the drawings for the purpose of understanding the present invention. In the following description, the front-rear direction is defined as the front side of the ejection port 41 where the staple S is launched, and the rotation axis side of each member is defined as the rear side. Further, the vertical direction is defined as the handle portion 2 side being upward and the base portion 5 side being downward when the base portion 5 of the stapler 1 is installed on the mounting surface.

First, the overall configuration of the stapler 1 according to the embodiment of the present invention will be described with reference to FIGS. 1 and 2. The stapler 1 is mainly used as a stationery for binding paper, and includes a handle portion 2, a driver portion 3, a magazine portion 4, and a base portion 5, and a staple remaining amount display is provided between the handle portion 2 and the driver portion 3. It has a mechanism 6. Of these, the handle portion 2 and the base portion 5 are integrally attached to the rear end side via the rotation shaft 54, and each member can rotate independently about the rotation shaft 54. ..

Here, it is not always necessary that the stapler 1 is mainly composed of the handle portion 2, the driver portion 3, the magazine portion 4, and the base portion 5. Other parts may be included in the structure of the stapler 1.

The handle portion 2 is a portion that is mainly grasped by the thumb of the worker's dominant hand and applies a force in the vertical downward direction when the operator uses the stapler 1 to drive the staple S into the binding paper. A through hole 21 is formed on the front side along a predetermined longitudinal direction of the portion 2 and at a substantially central portion in the lateral direction so that a part of the protrusion 63, which will be described later, can protrude. There is.

Here, the position of the through hole 21 formed on the handle portion 2 does not necessarily have to be the above-mentioned position. The position of the through hole 21 can be appropriately changed so that the position is generally gripped by the thumb when the operator works with the stapler 1.

The driver unit 3 has, for example, a function for embossing staples S on a spelling paper to be spelled. At the front end of the driver unit 3, a substantially rectangular plate-shaped punching piece 31 for launching the staple S from the punching port 41 toward the binding paper projects downward.

Here, the punched piece 31 does not necessarily have to have a substantially rectangular plate shape. The shape of the embossed piece 31 may be any shape as long as the staple S can be embossed on the binding paper.

The magazine section 4 mainly has a function of filling the staple S. At the front end of the magazine portion 4, a punching outlet 41 is formed so that the punching piece 31 can penetrate and the staple S is sequentially punched into the binding paper.

From the front to the rear of the magazine portion 4, there is an accommodating portion 42 for filling the staple S. In the accommodating portion 42, concave grooves having a width substantially matching the width direction of the staples S are formed so as to face upward, and a plurality of staples S connected in a bundle in the concave grooves are bundled into one mass. It is possible to accommodate as.

Further, the magazine portion 4 has a pusher 43 for sequentially pushing out the staples S accommodated in the accommodating portion 42 toward the ejection port 41. The front surface of the pusher 43 comes into contact with the staple S located at the rearmost of the staples S housed in the accommodating portion 42. Further, the rear surface side is always urged to the front side via the urging member 44, and is attached so as to be slidable in the accommodating portion 42. Further, on the upper surface of the pusher 43, a fitting recess 45 into which the fitting convex portion 62, which is a part of the staple remaining amount display mechanism 6 described later, can be fitted is formed as an opening upward.

Here, the fitting recess 45 does not necessarily have to be formed at the position shown in FIG. The fitting recess 45 may be formed at any position of the pusher 43 as long as it is formed upward.

The base portion 5 is composed of a substantially rectangular bottom surface portion 51 and a side wall portion 52. On the front side of the bottom surface portion 51, there is a clincher 53 in which a recess for bending the leg portion of the staple S launched from the ejection port 41 is formed. Further, the side wall portion 52 is erected so as to face each other in the vertically upward direction, and the rear end of the side wall portion 52 has a rotating shaft 54 through which the shaft pin 55 is inserted, and the handle portion 2 Is independently rotatable with the rotation shaft 54 as the base end.

Next, the staple remaining amount display mechanism 6 according to the embodiment of the present invention will be described. The staple remaining amount display mechanism 6 is mainly composed of a main body portion 61, a fitting convex portion 62, and a protruding portion 63, and a substantially central portion of the main body portion 61 with respect to the driver portion 3 via a shaft pin 64. It is pivotally supported so that it can rotate.

Here, the staple remaining amount display mechanism 6 does not necessarily have to be pivotally supported by the driver unit 3. However, since the main body 61 is pivotally supported by the driver 3, the main body 61 can be held more stably.

As described above, the main body 61 is formed with a through hole 68 into which the shaft pin 64 can be inserted, and the shaft pin 64 is inserted into the through hole 68 to rotate at a predetermined position of the driver portion 3. It is freely pivotally supported.

At one end of the main body 61, a fitting convex portion 62 that can be fitted into the fitting recess 45 formed in the pusher 43 is formed. A long hole 65 having a predetermined length is formed at the other end of the main body 61, and a protrusion 65 is formed via a shaft pin 69 so as to be slidable and rotatable in the long hole 65. The portion 63 is pivotally supported.

Here, the fitting convex portion 62 does not necessarily have to be integrally formed as a part of the main body portion 61 on one end side of the main body portion 61. For example, the fitting convex portion 62 may be prepared separately, and one end of the fitting convex portion 62 and the main body portion 61 may be fixed by a known fixing means.

Further, it is not always necessary that the elongated hole 65 is formed at the other end of the main body 61. However, since the elongated hole 65 is formed, a predetermined clearance can be secured, so that the rotational movement of the protrusion 63 can be made smoother.

The protrusion 63 is always urged downward by the urging member 66. A support leg 67 fixed to the protrusion 63 is inserted through the urging member 66, and the tip of the support leg 67 is penetratingly supported by a through hole 32 formed at a predetermined position of the driver portion 3.

In the above configuration, the function of the staple remaining amount display mechanism 6 will be described with reference to FIGS. 3A to 3F.

First, FIGS. 3 (a) and 3 (b) show the state of the staple remaining amount display mechanism 6 when the remaining amount of the staple S filled in the accommodating portion 42 of the magazine portion 4 is sufficient. When the remaining amount of the staple S is sufficient, the fitting convex portion 62 is in a state of being placed on the staple S, and at this time, the protrusion 63 is urged to the driver portion 3 side by the urging member 66. The state is maintained.

When the staple S continues to be used from the state of FIG. 3B, the pusher 43 moves forward accordingly. At this time, as shown in FIG. 3C, the relative distance between the fitting convex portion 62 and the pusher 43 becomes shorter, and the fitting convex portion 62 comes into contact with the vicinity of the front of the pusher 43.

Then, when the staples M in the accommodating portion 42 are further used and the remaining amount of staples M reaches a predetermined number (five in the figure), as shown in FIG. 3D, the pusher 43 is further accommodated. It moves forward in the portion 42, and at this time, the fitting convex portion 62 is fitted into the fitting concave portion 45.

When the fitting convex portion 62 is fitted into the fitting concave portion 45 of the pusher 43, an upward force acting on the protruding portion 63 in the direction opposite to the urging direction of the urging member 66 is applied by the reaction. At this time, the protrusion 63 moves upward against the urging force of the urging member 66, and a part thereof protrudes from the through hole 66.

In a state where a part of the protrusion 63 is projected from the through hole 21, when the operator tries to grasp and operate the handle 2 in order to start the next work with the stapler 1, the feeling of the protrusion 63 is felt. See it as a sense of discomfort. As a result, the worker can intuitively grasp that the remaining number of staples S has decreased, and can motivate the replenishment of the staples S into the accommodating portion 42.

When the work is continued and the staple S in the accommodating portion 42 disappears, as shown in FIG. 3 (f), the amount of protrusion of the protrusion 63 from the through hole 21 increases, and the operator becomes stronger through the feeling of the hand. Since it feels uncomfortable, it is possible to strongly encourage the worker to replenish the staples.

Here, it is not always necessary to put the fitting convex portion 62 and the fitting concave portion 45 in the mated state when the remaining number of staples S in the accommodating portion 42 is small. For example, when the staple S is completely eliminated, the fitting convex portion 62 and the fitting concave portion 45 may be in the fitted state, and the protruding portion 63 may be configured to protrude from the through hole 21.

In this way, since it is possible to notify the operator not only visually but also sensuously that the remaining number of staples has disappeared (or the remaining number has decreased), the worker can notify the remaining number of staples S. The chances of overlooking the loss (or loss) of numbers can be significantly reduced.

As described above, the stapler according to the present invention can prevent the staples from being idle by sensuously notifying the operator that the remaining amount of staples filled in the stapler is low. ing.
