Further, the mounting member 2 is provided with an electrostatic adsorption plate 24 that is an adsorption member for adsorbing and holding the member to be cut 23 placed thereon. This electrostatic adsorption plate 24 is activated by pressing the 6g switch 25 provided on the mounting member 2 with a corresponding pressing member 1d provided on the frame 1.

Reference numerals 26, 27, and 27' designate a first aligner and a second near liner, which are positioning members that respectively position the cut member 23 placed on the electrostatic adsorption plate 24 in the length direction and width direction. Among these, the above-mentioned near liner 27, 27' is configured to be movable in the directions of arrows T and J in FIG. 2, as will be described later.

28, 28' are mounting plates 29°2 fixed to the mounting member 2.
A gear 30.30' is rotatably mounted around this shaft 28.28'.

The long grooves 31b, 31b' engage with guide pins 29a, 29a' erected on the mounting plate 29, 29' as indicated by arrow T.

It is configured to be movable in the J direction. The slide gear 31.31' has spring hooks erected on the mounting plate 29.29' with pins 29b, 29b' and spring hooks vertically attached on the slide gear 31.31' with portions 31c, 31c'. The cut groove portion 2 formed in the mounting plate 29, 29' is biased in the direction of arrow T by a spring 32 hung between the grooves 29 and 29'.

Next, the configuration of the canter 6a+ is shown in FIG. 9(a) [
This will be explained with reference to

The cutter 6a+ is attached to a shaft 6b+ whose both ends are held by a cutter holder 7a. cutter 6a,
Rubber rollers 6b2. A cutter holding member 6bs is provided. A compression coil spring 6b4 is provided between the cutter holding member 6bs and the inner wall of the cutter holder 7a+ via a washer 6bs, and this compression coil spring 6ba causes the cutter 6a1. Rubber roller 6b2. The cutter holding member 6bs is integrally urged in the thrust direction (left side in FIG. 9(a)). A washer 6bi is provided between the rubber roller 6bt and the inner wall of the cutter holder 7a. For this reason, as shown in Figure 9(b), the force,
The target 6a+ is a guide plate 22 attached to the mounting member 2.
a, is in contact with the end portions 22a,' of.

Next, a cutting operation when cutting a member to be cut using the above-mentioned cutting device will be explained.

First, as shown in FIG. 3, a member to be cut 2 such as paper to be cut is cut.
3 is placed on the electrostatic adsorption plate 24 of the mounting member 2. At this time, the ends of the member to be cut 23 are brought into contact with the first aligner 26 and the second near liners 27 and 27' to perform positioning in the longitudinal direction and the width direction.

After placing the member 23 to be cut, the power switch 25 is pressed to activate the electrostatic adsorption plate 24 to attract and fix the member 23 to be cut. In this state, frame 1
Grip the handle 5 and rotate it in the direction of arrow A shown in FIG. 3 about the rotation axis 3.

At this time, the frame 1 is moved by the arrow B in Fig. 3 by the spring 4.
The pin 1b is biased in the direction and stopped by engaging the stopper 2b. Therefore, a certain amount of force is required to rotate the frame 1 in the direction of arrow A, but once the frame 1 rotates to a certain extent, the biasing force of the spring 4 acts in the direction of arrow A, so there is no problem. That is, the spring 4 is used as a clink spring.

When the frame 1 is retracted around the rotation axis 3 as described above, the cutter 5a+ installed on the frame 1 side,
6az and 6ax similarly rotate and descend onto the mounting member 2.

As mentioned above, a hole 1c is bored in the frame 1,
As shown in FIG. 4, pins 2 erected on the mounting member 2
The pin 2d also positions the frame 1 in the height direction with its shoulder 2dZ, and the elastic member attached to the shoulder 2dx positions the frame 1. 1 absorbs the shock when it descends.

Further, while the frame 1 is in the upper position, a safety bar 14 is arranged under the blade surface of the cutter 68g in the center to prevent the operator from touching the cutter 6at carelessly. Further, the cutting edges of the cutters 6a+ and 6as on both sides are attached to a cutter holder 78+, as shown in FIG.
It is protected by a safety plate 36, 36', which is a movement prevention member held at 7a.

While the frame 1 is lowering, the safety bar 14 is
As shown in FIG. 6(a), torsion coil springs 18, 1
8' is biased by the stopper part 15a of the safety bar holding plate 15 through the holding members 17 and 17', so that the cutting edge of the canter 6ax is covered.

When the frame 1 further descends, the holding member 17.
The cam portions 17a, 17a' of 17' abut against the inclined surfaces of the guide cams 2e, 2e' provided on the mounting member 2, and resist the biasing force of the torsion coil springs 18, 18'. and rotate in the direction of the arrow around pins 16 and 16'. As a result, the cutting edge of the cutter 6a2 at the center is exposed and the member 23 to be cut can be cut. At this time, the near liner 27, 27' retreats in the direction of arrow J in FIG. 2, which will be described later.

Further, when the frame 1 is lowered, the bending members 20a+, 20a, 20a3, and 20

21az, 21a, and 21a,', 21a,
′, 21a, presser plate 19al+1 held by ′
9az and 19a are also lowered to loosely press the member to be cut 23.

In this state, the operator pushes the bush holder 10 in the direction of the arrow R shown in FIG.
+, 7az, 7ai are also pushed and the member to be cut 23
can perform cutting operations.

Next, referring to Fig. 8, cutter holder 781゜7a
The operation of h 7 as will be explained.

The position of the snake in the figure indicates the initial position (cutting start position in the ■→■ direction and cutting end position in the ■→■ direction), and indicates the F
The position G indicates the position during cutting, and the position G indicates the cutting end position (cutting end position in the ■→■ direction and cutting start position in the ■→■ direction).

The above cutter holders 7a+, 7az, 7as
This will be explained with reference to a state in which, at the time of cutting, they are not lined up in a straight line in a direction perpendicular to the direction of movement, but are in the position shown at F in the figure.

The apparatus shown in this embodiment is for cutting both side edges and the center of a member to be cut 23. On both side edges of the member to be cut 23, unnecessary portions (chips) 23a during cutting escape in the directions of ■ and ■ as the cutters 6a+ and 6as advance in the direction from ■ to ■. In the central part, even if the canter 6a2 moves in the ■→■ direction, the cut member 23 is held down by the rubber roller 6b and the pressing plate 19az during cutting, so that the cut member 2
There were cases where the cut end of No. 3 could not escape in the ■ and ■ directions, and the cut end became rough or could not be cut properly. In particular, when the cutters 6a+, 6az, 6a3 are lined up horizontally, the cutting operation is likely to be extremely inconvenient.

Therefore, in this embodiment, cutters 681° 6a on both sides
The above problem is solved by allowing the canter 6a in the center to advance further than x. That is, inside the bush holder 10, there are cutter holders 7a+, 1a.
Hollow portions 10a, 10a to cover t, 1as
x, 10an are provided. Among these, the longitudinal dimension fz of the hollow portions 10a1 and 10ax on both the left and right end sides is the longitudinal dimension of the canter holders 7a+ and 7ai! .

It has almost the same dimensions. On the other hand, the longitudinal dimension N of the central cavity 10a* is the cutter holder 7a.
Longitudinal dimension of 2! It is configured larger than 3.

Therefore, when the operator moves the bushing holder 10 from the position shown in FIG. contact surface 10a,
The force center holder 7a2 does not move until it comes into contact with the contact surface 7a2' of the canter holder 7az, so that the force center holder 7a2 can be moved later than the canter holder 781.7a3. Also, bush holder 1
Similarly, when moving the cutter holder 7az in the ■→■ direction, the cutter holder 7az can be moved later than the cutter holders 7a+ and 7az.

Next, at the position of line I in FIG.
8++ Rubber roller 6c, held at 7as.

6c4 strongly presses the holding plates 19a+ and 19as,
The pressing plates 19a1 and 19as press the member to be cut 23, thereby preventing the member to be cut 23 from shifting during cutting.

On the other hand, at the position of line H, the holding plate 19a+
, 19a:+ loosely presses the member to be cut 23, so the cutter 6a held by the cutter holder 7az
When z cuts the center part of the member to be cut 23, the presser plate 1
Since the part marked ``■'' of the member 23 to be cut, which 9a2 faces, can escape a little in the direction ``black'', smooth cutting can be achieved.

Then, when the operator moves the bushing holder 10 further in the ■→■ direction and reaches position G shown in FIG.
The cutting operation ends. When the cutting is completed, the operator raises the frame 1 and removes the cut member 23.
or move the bushing holder 10 from position G to position E! After moving the frame 1 in the ■→■ direction, the frame 1 may be raised and the cut member 23 may be removed.

In this case, the power switch 25 of the electrostatic adsorption plate 24 is turned off because the pressing state by the pressing member 1d is released.
Thus, the adsorption of the member to be cut 23 is released. Press the power switch 25 once to turn it ON, press it again to turn it OFF.
This is a general momentary inch with F. The operator turns it on when cutting the workpiece 23, then lowers the frame 1 and presses the source inch 25 again with the pressing member 1d, but in this state. After cutting the workpiece 23, which is still in the ON state and does not affect the holding of the workpiece 23 during cutting, the frame 1
It is turned off only when the recording medium 23 is lifted, and the recording medium 23 is released from adsorption and can be easily taken out.

Therefore, the electrostatic adsorption plate 24 can prevent the member to be cut 23 from shifting when positioning and cutting the member to be cut.

Next, the operation of the cutter 6a+ during cutting is shown in FIG.
) This will be explained with reference to (b).

In FIG. 9(a), the rubber roller 6e is used during cutting.

In order to press the presser plate 19a+ against the guide member 22a, the member to be cut 23 placed on the guide plate 22a+ has the presser plate 19a and the guide member 22a.
1 and is firmly fixed.

Furthermore, since the end portion 36a of the safety plate 36 is inserted under the end portions 22a, ′ of the guide member 22a1 and the convex portion 2g of the mounting member 2 during cutting, it is difficult for the operator to raise the frame 1 during cutting. Even if the end 36a is the end 22
It is configured such that the frame 1 cannot be raised by being locked at the points a and '. Conversely, when the frame 1 is in a raised state, even if the frame 1 is lowered, the frame 1 cannot be lowered because the end portion 36a collides with the end portions 22a,'.

Therefore, if the safety plate 36 causes the cutter 6a to inadvertently raise the frame 1 while cutting the workpiece 23, the cutter 6a may fail to cut, and if the cutter 5a is stopped at the cutting position when not cutting, the frame 1 This prevents the machine from inadvertently lowering to the cutting position.

Further, as described above, at the cutting standby position of each cutter on the frame 1, there are cam members 13a+, 13az, 13a.
.

and 13a+', 13az', and 13an', and in the position shown in FIG.
a,, 13az, 13a3, and in the position shown in G, the cam members 13a,', 13az', 13a.

' are configured to engage with each other. As shown in FIG. 9(a), the cutter holder 7
a+ and 7az rotate in the direction of arrow M around guide rails 8a+ and 88z, and cutter holder 7a3 rotates in the direction of arrow N around guide rail 8as, resulting in the state shown in FIG. 11.

In this state, the end 36a of the safety plate 36 shown in FIG. 9(a) is prevented from interfering with the end 22a,' of the guide member 22a1, and the cutter 6a+ is protected.
It becomes possible to raise or lower the frame 1.

In this state, the elastic force of the compression coil spring 6el is received by the inner surface of the cutter holder 7a+ via the washer 6f1.

When the operator starts the cutting operation and moves the busher holder 10 in the direction ■→■ in FIG. 8, the cutter holders 7at, 7az, 7&S and the cam member 13a,
.

The bond with 13at and 13a□ is released. When the engagement is released, the cutter holder 7a+ rotates in the direction of the arrow N around the guide rail 8a+ due to the elastic force of the rubber roller 6c that was pressing the presser plate 19a, and the cutter 6a+ moves into the guide member. 22a, and the end surfaces 22a,' receive the elastic force of the compression coil spring 6e+ via the cutter 6a+.

Similarly, the canter 6az rotates the guide rail 8az in the direction of the arrow N, and the cutter 6a rotates in the direction of the arrow M around the guide rail 8a3, and the cutter 6az+
6aa is the guide member 22az, the end surface 22 of 22az

22as, it is clear that the member to be cut 23 cannot be easily cut, and it is necessary to press each cutter against the guide member with an appropriate force.

When the cutting of the member 23 to be cut is finished, the bush holder 10 reaches the position shown in FIG.
.

13az' and 13az', and the end portion 36 is engaged again.
Since the engagement with the end portion 22, + of a is released, the frame 1 can be raised to take out the cut member 23 after cutting.

In this embodiment, the cam members 13a1, 13az, 13a

When pressed against 228z' and 22a3', as shown in FIG. 9(b), the whole is pressed, so
Cutting can be performed well without causing damage to the cutting edge.

Next, the locking/unlocking mechanism of the bush holder 10 when the frame 1 is raised or lowered will be explained.

When the bush holder 10 is in the position shown in FIG. 8E, if the frame 7 is raised, it will slide down in the direction of the arrow P shown in FIG. 3, which will hinder the cutting operation in the ■→■ direction. Therefore, this embodiment is equipped with a locking mechanism described below.

Frame 1 has guide rails 8a+, 8az,
8a3 bearings 9a+, 9az, 9az and 9a
1', 9az', and 9a3+ are provided, respectively. On the other hand, on the bush holder 10, it is rotatably held by a lock arm 12.12' or a holding member 11.degree. 11'. The holding members 11, 11' are urged in the direction of the arrow Q shown in FIG. 4 by a spring (not shown), and are received by the upper surface of the push holder 10. The lock arm 12.12' also has a bearing 9a+' + provided with high friction members 12a, 12a'.
9as' to prevent movement of the bushing holder IO in the direction of arrow P.

When the frame 1 is rotated and lowered onto the mounting member 2 as shown in FIG. 2

+' and 9as', it is possible to prevent the bush holder 10 from slipping off in the direction of arrow P in FIG.

Next, regarding the operation of the 12th near liner 27 and 27',
(→°C) and FIG. 3 for explanation.

As described above, the operator positions the member to be cut 23 in contact with the first aligner 26 and the second near liner 27, 27', places it on the mounting member 2, and turns on the power switch 2.
Press 5 to turn the electrostatic adsorption plate 24 to ○N and attach the member to be cut 23.
is fixed by suction, and the frame 1 is rotated and lowered in the direction of arrow A shown in FIG. At this time, the slide plate 34 moves in the direction of arrow R in FIG.

When the slide plate 34 moves in the direction of arrow R, the rack 33 held by the slide plate 34 also moves in the direction of arrow R and meshes with the gear 30 during the movement. When the slide plate 34 further moves in the direction of arrow R, the gear 30 rotates due to the driving force transmitted from the rack 33, and the slide gear 31 meshing with the gear 30 moves against the elastic force of the spring 32 to rotate the gear 30.
Move in the direction of arrow J shown in Figure (a).

When frame 1 rotates further and reaches the state shown in Fig. 2, the first
As shown in Figure 2(a), the near liner 27°27'
(3), the rack 33 moves to the position (2).

As a result, as shown in Fig. 12 Φ), a space with a height of 0 width is created, but this is larger than the space shown with a height n and a width m shown in Fig. 9 (a). The canter 68 and the safety plate 36 can pass through the portion without any hindrance.

Conversely, when the frame 1 is rotated from the state shown in FIG. 4 in the direction of arrow B and raised to the state shown in FIG. 3
The meshing state between gear 3.33' and gear 30.30' is released, and slide gear 31.31', which is biased in the direction of arrow T by spring 32, has a bent end surface 31d.

31d' moves until it comes into contact with the cut grooves 29c, 29c' and then stops.

Therefore, when the frame 1 is in a lowered state as shown in FIG.
3 can be cut.

Next, a mechanism for moving the slide plate 34 as the frame 10 rotates will be explained with reference to FIG. 4.

As shown in FIG. 4, the bearings La, lag,
A rotating lever 35 is rotatably attached to the rotating shaft 3 of 1a. A pin 35a protruding from the tip of the rotary lever 35 is engaged with a cam groove 34a of the slide plate 34. Further, an elongated hole 34b is bored in a predetermined position of the slide plate 34, and a guide pin 2f provided upright on the mounting member 2 is engaged with this elongated hole 34b.

Therefore, in response to the rotational movement of the frame 1, the slide plate 34 is configured to move in the directions of arrows S and R via the rotation lever 35, as shown in FIG.

Further, the slide plate 34 is provided with elongated holes 34b at three locations, and since each elongated hole 34b moves while engaging with the guide pin 2f, the near liners 27, 27' are arranged as shown in FIG. Moves smoothly in the directions of arrows T and J without shaking.

As described above, the member to be cut 23 can be positioned in the length direction and the width direction by the first aligner 26 and the second near liner 27, and the member to be cut 23 can be cut in a short time and with good reproducibility.

<Effects of the Invention> As described above, the present invention cuts the workpiece placed on the placement member with a plurality of cutting members attached to the frame, so that accurate cutting operations can be performed in a short time. I can do it.

Further, by holding the holding member to the cam member in the cutting standby position, the blade surface of the cutting member can be separated from the guide plate to prevent interference and protect the cutting member.
