Description

[Detailed description of the invention] This invention relates to an electric stapler.

Conventionally, electric staplers have been proposed and implemented in which a solenoid drives a stable driving driver, but this type of stapler requires a relatively large amount of electricity to drive the driving driver, so it cannot be used indoors. There were disadvantages such as dim lighting, loud noises, and the time it took to store electricity in the capacitor, making it difficult to use it continuously.

This invention was developed in view of the above circumstances, and in particular, by using an electric motor, it is possible to drive quietly and smoothly even with a small amount of electric power. The purpose of this invention is to propose an electric stapler that can continuously form and punch out stable materials connected to the .

An example of implementing the present invention will be described below with reference to the drawings.

Figures 1 and 2 show the main parts of an electric stapler. A stable material accommodating section 4 capable of accommodating sheet-like stables (hereinafter simply referred to as staple materials) 3 formed in a sheet shape by connecting them with an adhesive in a multi-layered state; A feed passage 5 is formed at the front and introduces the lowest stage staple material 3a in the storage section 4 from the rear end and guides it to the front end; a feeding device for feeding the staple material 3 forward of the feeding path 5, a forming means 6 for sequentially forming the stable material of the staple material 3 into a U-shaped stable, and a forming means 6 for forming the stable material formed by the forming means 6 into a paper. The base 1 is provided with a drive device for driving the feeding device, the forming device 6, and the drive device 7 by an electric motor 9, and a drive device for driving the feeding device, the forming device 6, and the drive device 7 by an electric motor 9. A control means for controlling the drive in a single cycle is provided.

Next, the structure and operation of each member of the electric stapler will be explained in detail.

First, as shown in FIG. 2, the magazine member 2 is connected to the base 1 via a connecting shaft 10 so as to be able to swing within a certain range, and is normally biased in one direction by a spring 11. .

A stable material accommodating portion 4 is provided in the magazine member 2''. This staple material storage section 4 has a storage space that can store staple materials 3.3.3 * a in a multi-stage stacked state, and only the lowest stage staple material 3a is exposed to the outside at the lower end of the front wall. A lead-out outlet 13 is formed. Furthermore, a strip-shaped opening 14 is formed in the bottom of the staple material storage portion 4 in the front-rear direction. The central part of the lower surface of the lowest staple material 3a is the opening 14.
exposed downwards.

Further, a suppressing member 15 is provided above the uppermost staple material 3n in the staple material storage section 4, and the staple material 3 is always pressed downward by this pressing member 15 to maintain an appropriate posture. . In addition, the stable material storage section 4
When loading the staple material 3 into the staple material storage section 4, it is preferable that a cassette containing a large number of staple materials be installed in the staple material storage section 4 in advance.

A feed passage 5 for guiding the movement of the staple material 3 is formed in front of the stable material accommodating portion 4 . The rear end of this feed passage 5 opens into an outlet 13 of the stable material storage section 4 . Then, the staple material 3a at the lowest stage in the stable material storage section 4 is fed into the feeding path 5 by the feeding device.

The feeding device is composed of a feeding belt 16 provided facing the bottom opening 14 of the staple material storage section 4 and a magnet 17 provided on the back side of the feeding belt 16. The feed belt 16 is stretched around a pair of pulleys 18,19. One pulley 18 is provided near the rear end of the feed passage 5 of the magazine member 2, and the other pulley 19 is provided on the connecting shaft 10 that connects the magazine member 2 to the base l. This pulley 18,19 is also linked via a drive belt 20 to a drive device to be described below. The magnet) 17 uses a permanent magnet or the like and is provided below the bottom opening 14 of the stable with the feed belt 16 in between. Note that, as will be described later, since the drive device is driven for a certain period of time when driving the stable, the feed belt 16 also rotates for that period of time accordingly.

With the feeding device configured as described above, the staple material 3a at the lowest stage in the staple material storage section 4 is strongly attracted onto the feeding bell 16 by the magnetic force of the magnet 17. In this state, when the pulleys 18 and 19 are driven, the feed belt 16
Since the frictional resistance between the staple material 3a and the lowermost stable material 3a is very large, the staple material 3a moves following the movement of the feed belt 16, and is fed into the feed passage 5 from the outlet 13. When the rear end portion of the staple material 3a is fed out from the outlet 13 of the staple material accommodating portion 4, the next stage staple material 3b pushed down by the pressing member 15 descends to the lowest stage and is fed in the same manner as described above. It is fed out by the device into the feeding path 5 and connected to the rear end of the previous staple material 3a. Thereafter, the staple materials in the staple material accommodating portion 4 are sequentially fed into the feeding path 5 by the feeding device.

According to the above-mentioned feeding device, it goes without saying that the amount of movement of the feeding belt 16 is more than the width of one staple material. The rear end of the previous stable material already in the feed channel 5 can be pressed. Therefore, even if a gap occurs between the rear end of the previous staple material in the feed passage 5 and the front end of the subsequent stable material for some reason, the subsequent staple material will be immediately moved to the front end by the drive of the feeding device. Connect to the rear end of the staple material and press the previous staple material forward. For this reason, both staple materials do not wobble or play within the feeding path 5, and are fed while always maintaining an aligned state, so that stable forming is performed in the next stage.

On the other hand, some stapler feeding devices that use a long, continuous coiled staple material are configured to sequentially engage and feed out the staple material one by one using a feeding claw and a non-return claw. However, when this type of feeding device is used as a feeding device for a series of sheet-like stable materials, for example, when feeding out the next staple material after the previous staple material, the feeding claw may fail to engage even once. Therefore, when empty feeding occurs, a gap for one staple is created between the front and rear staple materials. If a gap is created between the front and rear staple materials in this way, the staple materials are bonded to each other at the driving part, so each time a staple of the previous staple material is driven, that staple 1
Because it moved forward by the length of the wood, the front and rear stable members moved by the same amount at the same time, and for this reason, once a gap was created between the front and back, this gap was never clogged.

Therefore, this gap part becomes a blank drive when driving,
This will impair office efficiency. In addition, the front stable material moves forward even without a pushing force from behind, but if there is no pushing force, it will tilt in the feed path 5, shift its position from side to side, and wobble, so-called "playing". This causes spelling errors. Furthermore, if the above-mentioned feed claw is to be provided at the output port 13 of the stable material with the feed accuracy of one staple material, the accuracy of the installation position will be strictly required, and realistically, extremely difficult.

As described above, the stable materials 3 in the staple material accommodating portion 4 are sent out from the rear end opening of the feed passage 5 to the front end opening in order from the lowest one by the feeding device. The fed-out stable material 3 is sequentially formed into a U-shape starting from the staple material at the front end, and is then driven in.

Next, the forming and driving structure of the staple material 3 and its operation will be explained in detail with reference to FIGS. 3 to 12.

As shown in FIGS. 3 and 4, a stopper convex portion 21 is formed on the upper surface of the front end opening of the feed passage 5, and an anvil 22 is formed on the lower surface, and staple butchers 23 are provided on both sides of the anvil 22 with springs. 24, and a face plate 2 is provided in front of the feed passage 5.
5 is provided. This face plate 25 is formed into a U-shape, is attached to the magazine member 2, has an opening 26 in the upper center part, and has a front end opening of the feed passage 5 on the back side of the front wall part 25a, which is about the same as the stable material. They face each other with an interval of one tree length. Furthermore, a holder 27 is held inside the face plate 25 so as to be movable up and down.
This holder 27 includes a forming means 6 for forming the staple material into a U-shape on the anvil 22, a table presser 28 for pressing and holding the staple material at the rear of the staple material to be formed during forming, and a pusher 23. A drive means 7 for punching out the extruded and molded stable is held.

The holder 27 is made up of a U-shaped front wall 27a and side walls 27b, 27b, with a bottom plate 27C provided at the bottom of the front wall 27a, and side walls 27b, 27b. The guide groove 31 is shaped, and
A spring holder 32 is provided between both side walls 27b, 27b. The drive rod 29 is connected to a drive device which will be described later. Furthermore, a cylindrical holding protrusion 33 and an opening 34 are formed in the front wall 27a. A leaf spring 35 is fixed to the bottom plate 27c, and a tapered tip 35 of the leaf spring 35 is fixed to the bottom plate 27c.
a projects forward from the front wall opening 34. The stay mold presser 28 is formed into a plate shape, and the upper end is provided with a piece 36, 36 for a spring receiver that protrudes rearward, and a long hole 37 is provided in the center.
is formed. The forming means 6 is formed into a plate shape, and a holding protrusion 33 of the holder 27 is provided at the center of the forming means 6.
A holding hole 39 is formed in the lower part of the long hole 38 to fit and hold the tip of the leaf spring 35, and a leg part 40 is provided on both sides of the lower end, and a leg part 40 is provided in the center part. Four portions 41 each having a shape corresponding to the continuous cross-sectional shape of the stopper convex portion 21 and the anvil 22 at the front end of the opening of the feed passage 5 are formed. Furthermore, the drive means 7 is formed in a plate shape, and the holding holes 4 are tightly fitted into the holding protrusions 33 of the holder 27.
2 is formed, and an escape hole 43 larger than the tip of the leaf spring 35 is formed in the lower part thereof. Note that the lower end surface of the stall mold presser 28 is about three times the width of one stable material, and the thickness of the forming means 6 and drive means 7 is about the same width as the width of one stable material. It is formed like this. Incidentally, the wall pressure of the staple mold presser 28 may also be approximately the same as the wall thickness of the forming means 6 and the drive means 7.

A mounting rod 44 passes through the guide groove 31 of the holder 27, and both ends of the penetrating rod 44 pass through the mounting holes 2c of the side walls 2a, 2a of the magazine 2 member 2 and are fixed thereto. This allows the holder 27 to move up and down by the length of the guide groove 31 while being held by the face plate 25. Further, a spring 45 is interposed between the bottom plate 27c of the holder 27 and the upper surface of the staple material feeding passage 5, so that the holder 27 is always urged upward. next,
A stapler presser 28, forming means 6, and drive means 7 are held on the front wall of the holder 27 between it and the face plate 25. That is, the stay mold presser 28 has a spring holder on the piece 36, and the spring holder on the holder 27 has a rod 32.
By interposing a spring 46 between the forming means 6 and the forming means 6, the forming means 6 is always held in a downwardly biased state, and the tip end 35a of the leaf spring 35 fixed to the holder 27 is fitted into the holding hole 39 of the forming means 6. Furthermore, the drive means 7 is held by fitting the holding convex portions 33 of the holder 27, which pass through the respective elongated holes 37, 38 of the staple presser 28 and the forming means 6, into the holding holes 42 of the drive means 7. There is. The stamol presser 28 and the forming means 6 are connected to the anvil 22 by straddling the stopper protrusion 21 that protrudes forward from the opening of the feed passage 5.
Facing the top surface, the drive means 7 is provided so as to face the staple driving gap formed between the anvil 22 and the face plate 25. The stable driving gap is defined by two guide protrusions 47, 47 (eighth
Figure) is formed between.

Next, the functions of the above-mentioned stapler presser 28, forming means 6, and drive means 7 will be explained.

As described above, when the stable material 3 is sent out from the front end opening of the feeding passage 5 by the feeding device, the front end of the stable material 3 touches the protrusion 47 of the face plate 25, as shown in FIGS. 5 to 8. It hits .47 and stops on anvil 22.

Next, when the drive rod 29 provided on the holder 27 is driven downward by the drive device, the holder 27 moves downward, and the staple presser foot 28, forming means 6 and drive means 7 follow this. Move down. Then, as shown in FIG. 5(a), the forming means 6, which has moved downward, uses its legs 40, 40 to fix the staple material 3.
Push down both sides of the staple material pi at the front end of the staple material pi, and push down the tapered surface 23a on the upper part of the front wall of the stable butcher 23 as shown in FIGS. 6(a) and 6(b).
Move 3 back. The stable material p1, whose both sides have been pushed down, is further pushed down into the recess 4 of the forming means 6.
1, it is bent and formed into a U-shaped stable q.

On the other hand, the staple presser foot 28 holds the staple materials p2, p3, and p4 of the three staple materials p2, p3, and p4 from the second from the front among the staple materials 3.
These staple materials p2, p3, p4 are moved upward to the anvil 22 by the pulling force of the spring 46.
Keep suppressed on top.

When the front end staple material p1 is bent and formed by the forming means 6, it is separated from the second staple material p2. In this case, when the staple material is in the form of a sheet, the second staple material p2 is connected to the third and subsequent staple materials p3, p4, etc., so that its posture can be maintained. If the staple material is consumed and the second staple material p2 is at or near the rear end of the sheet, this staple material and the following staple material will not be sufficiently connected and maintained. , when the pressing force of the forming means 6 is applied and the bond with the front end stable material p1 is broken, there is a possibility that it will tilt as shown in FIG. If the staple material p2 is tilted in this way, good molding cannot be obtained. However, when the front end staple material p1 is formed by the forming means 6, the staple presser foot 28 descends onto the staple p2 and is further biased by the spring 46, so that the second staple material p2 is pressed and held on the anvil 22. Therefore, the tilting can be effectively prevented.

5. During molding, the forming means 6 is held by the leaf spring 35 of the holder 27, so its movement amount is the same as that of the holder 27, but the anvil 22 is moved further than the lowest point at which the forming means 6 can move. It is located slightly above. Therefore, when the holder 27 reaches the lowest point shown in FIG. 6(b) from the initial position shown in FIG. Because I can't do it,
The leaf spring 35 is bent, and the forming means 6 is urged downward by the spring pressure. When the forming means 6 reaches the actual lowest point shown in FIG. 5(b) from the initial position shown in FIG. 5(a), the staple material is formed into a U-shape. Forming is ensured by the additional compression force. On the other hand, when such surplus force is not applied, the molding pressure is not sufficient, and when the pressure is released, the stable material to be molded returns to its original shape slightly, causing its crown to become rounded. Otherwise, the legs may become hooked, which may cause poor driving. The effect of the suppressing surplus force as described in item 2 is particularly remarkable when the forming means 6 is configured to rise immediately after reaching the lowest point.

The drive rod 29 is then driven upwards by the drive device,
The repulsive force of the spring at the bottom of the holder 27 is also added to this, causing the holder 27, the staple presser 28 held therein, the forming means 6, and the drive means 7 to move upward, and the pressure on the staple material 3 is released. When the drive means 7 moves upward, the formed staple material pi and the subsequent staple material p2 are partially bonded, so that
The subsequent staple material p2 also attempts to follow the upward movement of the forming means 6, but the upward movement of the staple material p2 is blocked by the stopper convex portion 21. When the pressing force on the staple material 3 is released, the backward holding force on the stable button 23 is also released, so that the staple material 3a is moved by the pressing force of the stable button 283 and the feed pressing force of the feeding device. The stable material pushed forward and formed into a predetermined U-shaped staple q1 is fed into the driving gap between the parallel protrusions 47 and 47 of the face plate 25 shown in FIG. It is held between the back surface of the staple button 25a and the staple button 23.

Furthermore, when the holder 27, the staple presser 28, the forming means 6, and the drive means 7 are moved downward again by the drive device, the staple q in the driving gap is driven out by the drive means 7. At this time, since the staple q is held between the front wall 25a of the face plate 25 and the staple button 23, the staple q is stably and reliably driven into the binding material 8 without being tilted. and a stable material p2 that is connected to the staple material p1,
p3: The fist is formed in the same manner as described above, and thereafter the staple materials are sequentially formed and punched in the same manner.

Next, the above-mentioned staple material feeding device and the driving device for driving the holder 27 will be explained. As shown in FIGS. 9 and 10, this drive device transfers the rotational force of the drive motor 9 to a rotation shaft 9a of the drive motor 9.
After being decelerated by the reduction gears 48, 49, 50 meshing with the gears 48, 49, 50, the transmission is transmitted to the pulleys 18, 19 of the two-stage feed device and to the link mechanism linked to the drive rod 29 provided on the holder 27.

First, a pulley 59 is fixed to the central drive shaft 51 of the last reduction gear 50, and a drive belt 20 is stretched between this pulley 59 and one pulley 19 of the feeding device. As a result, when the drive motor 9 rotates, its rotational force is transmitted to the pulleys 18 and 19 of the feeding device via the drive shaft 51 and the drive belt 20, and the feeding operation of the staple material 3 is started.

Further, cams 52 are fixed to both ends of the drive shaft 51,
This cam 52 is linked to a link mechanism. The link mechanism includes a pair of L-shaped links 54.54 linked to both ends of the drive rod 29 provided on the holder 27 via connection links 53.53, and the cam 5 described above.
2 and a motor link 55 connected thereto. The central part of each rim-shaped link 54.54 is pivotally connected to the side plate 56 of the base l, and one end thereof is linked to the connecting link 53.53, and the other end is connected to the connecting link 57.
connected by. The motor link 55 is formed in a U-shape, and both ends thereof are linked to the cam 52 of the drive shaft 51. Therefore, when the drive motor 9 rotates,
The rotational force is transmitted to the drive shaft 51, the cam 52 rotates, the motor link 55 reciprocates in the front and back direction, and the L
Since the shaped link 54 swings around the pivot shaft 58, this swinging motion is converted into a reciprocating motion at the connecting link 53, which causes the drive rod 2 provided on the holder 27 to
9 reciprocates up and down, and the holder 27, the stapler presser 28, the forming means 6, and the drive means 7 are driven up and down in a two-way manner. When the drive shaft 51 rotates 11 times, the holder 27 reciprocates up and down once.

By the way, when the drive means 7 is operated by a normal link mechanism, its stroke amount is constant, but on the other hand, the thickness of the binding material 8 varies depending on, for example, the number of sheets of paper to be bound. The stroke amount of the means 7 must also vary according to this thickness, and if this is fixed, spelling errors will occur. Similarly, if an unexpected abnormal load is applied to the drive means 7, such as when the drive means 7 is driven when a steel member is caught on top of the binding board 12 for some reason, the motor may lock. There is. Further, in the case of a link mechanism, the phase of the stroke of the drive means 7 is likely to be erroneous with respect to the design due to the link length, dimensions, gaps, etc. between the link and the pin, which may cause spelling errors. Therefore, it is necessary to adjust the phase of the stroke by the amount of error. Therefore, in this stapler 2, as shown in FIGS. 9 to 11, the connecting link 57
and the motor link 55 are connected by a connecting bolt 60, and the connecting port 60 is provided with two receiving plates 61 and 62 between the connecting link 57 and the motor link 55. A compression spring 63 is interposed between the plate 61 and the other receiving plate 62, and a spring pressure adjusting nut 64 and a phase adjusting nut 65 are screwed between the plate 61 and the other receiving plate 62.

” - According to the notation structure, the motor link 55 and the connecting link 5
Since a compression spring 63 is provided between the link mechanism and the link mechanism 7, a part of the stroke amount obtained by the link mechanism can be absorbed by the compression spring 63. in this way,
Since the difference in thickness of the binding material 8 is absorbed by the compression spring 63, the stroke amount of the drive means 7 is automatically adjusted, and good binding can always be obtained. Note that the torque of the drive motor 9 is set to an extent that can withstand the load applied in the event of an abnormality, and the spring pressure of the compression spring 63 is set so that at least the maximum amount of deflection is obtained when the motor torque reaches the maximum. I'll keep it. This spring pressure can be easily adjusted by turning the spring pressure adjustment nut 64, and by setting it as described above, the drive motor 9 will be locked even if an unexpected load is applied to the drive means 7. Never happened.

Also, if you turn the phase adjustment screw 65, the motor link 55
Since the distance between the connecting link 57 and the connecting link 57 can be adjusted, the stroke phase of the drive means 7 can be adjusted. That is, as shown in FIG. 12, if the distance between the motor link 55 and the connecting link 57 is increased, the L-shaped link 54 will rotate by that amount, and the phase of the stroke will be adjusted by h, thereby changing the position of the holder 27. goes down. On the other hand, if the above-mentioned interval is made smaller, the position of the holder 27 is raised, so the phase of the stroke of the drive means 7 can be easily adjusted, thereby adjusting errors in member dimensions, etc., and 4. Always maintaining good spelling performance. It is possible to keep it.

The drive device described above is driven and controlled in a single cycle by a control device including the following three switches shown in FIG.

The switch swl has an actuator 70 on the side of the binding table 12.
It is located with. This actuator 70 is pressed by the binding material 8 when the binding material 8 is set on the binding base 12 and is activated, turning on the switch swl. The switch sw2 is provided opposite to a cam 71 attached to the drive shaft 51 of the drive device, and contacts and separates from the cam 71 every time the drive shaft 51 rotates once, turning it on and off instantaneously. The switch sw3 is provided in contact with one end 72a of the stable material detection member 72. This detection member 72 is connected to the connecting shaft l.
The free end portion 72b thereof is provided facing the opening of the staple material accommodating portion 4. When there is no stable material 3 in the storage section 4, the stable material detection member 7
The free end 72b of 2 is inserted into the housing part 4, and the detection member 72
As the switch rotates, the one end 5 portion 72a is separated from the switch sw3, thereby turning on the switch sw3.

Therefore, the operation of the above-mentioned switch and drive motor 9 will be shown together with a timing chart in FIG. 14. First, when the binding material 8 is set on the binding table 12, the actuator 7
0 is activated, switch swl is turned on, rectified into a rectangular wave by the one-shot circuit, and turned off (waveform diagram of A)
. The drive motor 9 rotates simultaneously when the switch swl is turned on, and continues to rotate even when the switch swl is turned off. When the drive motor 9 rotates and the drive shaft 51 rotates once, the cam 72 turns on and off the switch sw2, and the drive motor 9 stops at the same time as the switch sw2 is turned on (waveform diagram B). Next, when the switch sw3 is turned on while the drive motor 9 is rotating, the drive motor 9 does not stop rotating until the switch sw2 is turned on, but does not start even after the switch swl is turned on (waveform diagram C).

A control device operating as described above can be obtained, for example, by the circuit configuration shown in FIG. 615. Therefore, the operation of the above-mentioned control device will be explained with reference to the same figure.
First, the worker sets the binding material and the switch Swl is turned on (closed state in the figure).
One input terminal of the NANO gate N, which is connected to the power supply 73 and has been at Low (O level) until then, becomes the positive voltage gh (t level) of the power supply 73. On the other hand, since the stable material detection switch sw3 is in the OFF state while the stable material is present in the storage section 4, the inverter I connected to it is in the Log (0 level) input state, Its output is in the old gh (lebel) state. As a result, both of the two input terminals of the above-mentioned HAND gate N1 become the old gh, and their output becomes Low. This is inverted by the next stage inverter I2 and input to the one-shot multivibrator MV. The other input terminal (reset terminal) of this one-shot multi-by-break MV is connected to switch S%T2. This switch sw2 is configured to be turned on by the cam 71 of the drive shaft 51 at the end of driving the stable, and until then it is in the off state and the Lo
This is an input state of w (O level). Therefore, when the binding material is set by the operator, only the switch SW1 is turned on in the normal state, and the old gh (i level) signal is applied to the set input of the one-shot multi-by-break MV. As a result, predetermined output signals are generated at Ql, Ql, and ℃2 of the one-shot multivibrator MV, respectively, and the above-mentioned The output signal is supplied, and the output of the NOR gate NR becomes Low (O level). As a result, the drive motor 9
Darlington connected transistor TR connected in series with
Since the base input of o becomes LOV, the transistor TR
D is turned on. At the same time, this Low signal is inverted by the inverter I3 and becomes a High signal. This old g
Since the h signal is supplied to the PNP transistor TR, this transistor TRP is turned off, and the subsequent NPN transistor TRN connected to it is turned off.

To further summarize the above operation, the operator switches the
When l is turned on, one-shot multivibrator MV
enters the operating state. As a result, the NOR gate NR,
The output signal becomes Low, and the drive motor 9 and power supply 73
The Darlington connection transistor ↑Ro connected in series between is turned on, and a voltage is applied to the drive motor 9 from the power supply 73. At the same time, the above-mentioned Low signal is inverted and applied to the transistor TRy connected in parallel to the drive motor 9, so that the transistor TR,
+ is off. Therefore, after the drive motor 9 starts rotating, it continues to rotate until the switch sw2 is turned on again. Next, when the cam 71 turns on the switch sw2, the old gh signal is supplied to the reset terminal of the one-shot multivibrator MV. This inverts the output signal state of the one-shot multivibrator MV.

As a result, the output 9 of the IOR gate) NR becomes the old gh, and the transistor TRIJ connected in parallel with the drive motor 9 is turned on. That is, the power supply voltage applied to the drive motor 9 is no longer applied because a short circuit is formed by turning on this transistor, and the drive motor 9 rapidly stops. This returns the one-shot multivibrator MV to its initial state.

By setting the binding material again and turning on the switch swl, the above-described series of stable driving operations are performed and the sequence is controlled so that the original state is returned.

Next, the operation when there is a shortage of stable material in the storage section will be explained. That is, the above-mentioned shortage condition generally occurs when the switch swl is on and the drive motor 9 is rotating, and the switch sw2 is off. In this case, the switch sw3 is turned on and the High signal is output to the inverter 11.
, NAND gate N, and inverter Iz, this one-0 shot multivibrator MV maintains an activated state for a certain period of time due to its inherent characteristics by turning on the switch swl. , the driving operation of the staple material is continued. However, once the switch sw2 is turned on and the staple driving operation is completed, the switch sw3 is kept on mechanically, so one input signal of the HAND game (N+) is always Low, so the switch sw3 is kept on mechanically. Even if swl becomes the old gh, its output will always be the old gh, and the one-shot multivibrator MV will not change its state. That is, this stopped state is maintained until new stable material is replenished, so even if the binding material is set, the stable driving operation is not started.

As described above, according to the control device, the drive device is controlled so that the drive motor 9 stops every time the drive shaft rotates once, so the torque loss of the drive motor 9 is small. In addition, even if the stable material 3 runs out in the stable material accommodating portion 4, the drive device is controlled in a single cycle, so there is no chance of staple damage. Moreover, when the staple material runs out in this way, the drive device does not operate until the storage section 4 is filled with staple material again after one cycle, so the staple material in the feed passage 5 is stored by the feeding device. Since a pressing force is constantly applied from the rear due to the feeding of the stable material within the section 4, good spelling can be achieved. Since the cam 71 is operated simply by contacting and separating from the switch sw2, its shape is simple.

In contrast, the worker operates the switch on and off,
Once turned on, the drive motor is allowed to rotate continuously, but it is also conceivable to control the rotation of the motor using a mechanical brake and clutch for each cycle of the drive shaft. However, when controlling the rotation of the drive motor mechanically in this manner, not only does a loss occur in the motor torque, but also a clutch and a brake are provided, making the device complicated and large-scale. Furthermore, even if the rotation of the drive motor is stopped using the brake, overruns tend to occur, making it difficult to accurately synchronize the cycle of the drive shaft with the actual stopping and restarting. Furthermore, since the drive motor is switched off manually, it is difficult to synchronize with the cycle of the drive shaft, so it is almost impossible to accurately return the above-mentioned drive device and other devices and means to their initial states. .

As explained in detail above, the electric stapler according to the present invention has a staple material storage that can accommodate sheet-like staples formed by connecting a large number of wire staple materials with adhesive and stacked in multiple stages. a feed passage formed in front of the stable material storage section to introduce the sheet-shaped stable in the storage section from the rear end and simply guide it forward; and a feed path for feeding out the sheet-shaped stable from the stable storage section. 3. A device, a forming means for sequentially forming the staple material of the sheet-like staple sent forward of the feeding passage into a U-shaped staple, and a forming means for forming the staple material formed by the forming means into a binding material such as paper material. A driving device for driving the feeding device, the forming device, and the driving device by an electric motor, and a control device for driving and controlling the manual device in a single cycle. It is something. Therefore, since it uses a motor, it can operate with low electric power, has quiet operation noise, and can operate smoothly.

(3) Delete "This invention..." from line 4 to line 19 of page 2, and amend it as follows. "This invention relates to a stapler. Conventionally, an electric stapler in which a stable driving driver is driven by a solenoid has been proposed and implemented.
This type of stapler requires a relatively large amount of power to drive the driving driver, so it may cause problems such as dimming the indoor lighting, making loud noises, or taking a long time to store electricity in the capacitor, making it difficult to use continuously. There were drawbacks such as the inability to This invention was developed in view of the above circumstances, and in particular, even when an electric motor is used, the power consumption is low, the drive is quiet, and the drive can be performed smoothly. The purpose of this invention is to propose a stapler that can continuously form and punch stable materials connected in a shape. (4) From page 33, line 9 to page 34, line 10, ``I can explain in more detail.'' is deleted and amended as follows. "As explained in detail above, the stapler according to the present invention is a staple material that can accommodate sheet-like staples, which are formed by connecting a large number of straight stable materials with adhesive and are stacked in multiple stages. a storage section, a feed passage formed in front of the stable material storage section to guide the sheet-shaped stable in the storage section to the outside of the storage section, and send out the sheet-shaped stable from the stable storage section to the feeding path. a feeding device; a forming means for sequentially forming the stable material of the sheet-like stable sent forward of the feeding path into a U-shaped stable; and a forming means for forming the stable material formed by the forming means into a paper material or the like. Since it is equipped with a drive means for driving into the material, and a drive device for driving the above-mentioned feeding device, forming means, and drive means, it is possible to create a stable material in which straight unformed stable materials are connected in a sheet shape. Not only can it be hammered out after continuous forming, but if a motor is used to drive the rotational drive shaft, it can operate with less power than conventional solenoid drive systems, and its operation is quieter.
