Abstract

PURPOSE:To obtain a good linearity of the cutting section even through a medium having a low rigidity in the direction square to the medium surface is cut. CONSTITUTION:By moving a round edge (movable edge) 35 along a fixed edge 36 to cut a medium 22, a bearing 44 moving together with the round edge 35 is engaged with a presser member interlock plate 38 to press down the interlock plate 38, and a presser member 37 is lowered together with a bracket 18, so as to squeeze and fix the medium 22 near the cutting position. Since the medium 22 is cut by moving the round edge 35 under such a condition, the cutting section is made in a good linearity even though a medium with a low rigidity in the direction square to the medium surface (the up and down direction) is cut. When the round edge 35 does not cut, the bearing 44 is engaged to the position lower than the step 38c of the presser member interlock plate 38, so as to make the presser member 37 in a refuge position.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting medium such as a printing medium such as a long paper, a cloth, a label, etc. on which printing is continuously performed in a strip shape (hereinafter simply referred to as "medium" in this specification). Relates to a cutter device that cuts a sheet to a predetermined length with a movable blade and a fixed blade, and particularly to a cutter device suitable for cutting a medium having low rigidity in a direction (out-of-plane direction) orthogonal to the medium surface.

[0002]

2. Description of the Related Art Conventionally, a circular blade (moving blade) that moves in this way
As a cutter device for sequentially cutting a strip-shaped continuous medium into a predetermined length by means of a fixed blade and a fixed blade, for example, as shown in a simplified form in FIG. The medium 2 to be cut stopped at the cutting position,
One side end 2 in the direction of arrow B orthogonal to the transport direction of the medium 2
There is one that cuts with a round blade 3 cut from the a side and a fixed blade 4 fixed to one end of the guide plate 1 along the moving direction of the round blade 3.

Further, as shown in FIG. 21, a fixed blade 8 swingably supported by a shaft 7 is pressed against a rotary blade 6 which is rotated by a motor 5 in an arrow direction by a biasing force of a spring 9, There is also one that cuts to a predetermined length while pressing a strip-shaped cutting medium inserted between the rotary blade 6 and the fixed blade 8.

[0004]

However, in the case of a cutter device which cuts by cutting the above-mentioned round blade from one side end side of the band-shaped cutting medium so as to traverse the medium,
When the medium to be cut is a thin paper, a cloth label, or the like, the resistance at the time of cutting generated between the round blade 3 and the medium 2 to be cut as shown in FIG. Deformation in the direction (out-of-plane deformation) occurs and the cutting medium is easily twisted and cut.

As a result, the cut surface of the cut medium becomes poor in linearity, and it is difficult to obtain a clean cut surface. Further, in the case of the guillotine type cutter device as shown in FIG. 21, the linearity of the cutting surface is easily obtained as compared with the round blade type cutter device, but when the medium is cut, the round blade type cutter device is used. Since a large cutting resistance is generated compared to the above, in order to be able to repeatedly cut at a sufficient speed, it is necessary to have a drive source with a large capacity commensurate with it, which makes the cutter device large. However, there is a problem in that the power consumption is increased as well as the power consumption.

Therefore, as an example of an attempt to improve the linearity of the cut surface of a medium to be cut in a cutter device using a round blade and a fixed blade, the present applicant has previously filed Japanese Patent Application No. 3-2881.
In the application of No. 47 (stacker device), a pressing roller is shown.

A cutter device provided in a printing device having this stacker device rotates a round blade 3 as shown in FIG. 22 (the parts corresponding to those in FIG. 20 are designated by the same reference numerals). On a carriage 15 which is freely supported and reciprocates in the direction of arrow C, presser rollers 13 and 13 are rotatably provided at the open lower ends of a presser arm 12 which is swingably supported at a fulcrum 11, respectively. 3 is moved to the right in the figure (the same applies when returning from right to left), and the fixed blade 4 and the medium 2
At the time of cutting, the medium 2 is pressed by the pressing rollers 13 and 13 so as not to escape so that the medium 2 is not deformed even if a cutting resistance occurs.

However, even with this cutter device, the pressing roller 13 rolls in the direction of the force that causes the medium to be cut to deform in the Z direction (deformation in the out-of-plane direction) as shown in FIG. Since the direction of the frictional resistance generated at the time coincides, it was not sufficient to suppress the deformation at the time of cutting the medium and obtain the linearity of the cut surface.

Further, in a printing device such as a thermal printer which is generally provided with such a cutter device, when a cloth label or the like is used as a printing medium,
The medium is likely to be charged with static electricity in the process of bringing the medium and the ink ribbon into close contact with each other for heating and printing by the thermal head, the process of peeling the ribbon by the ribbon peeling plate, and the like.

And, such a cloth label is shown in FIG.
Since the rigidity in the direction orthogonal to the medium surface indicated by arrow Z is low, it is likely to be deformed in the process of conveyance, so that the escape by the upper and lower guide plates (the upper guide plate is omitted in FIG. 20) is suppressed. It was easy to deform at the part where the forced force was released (breaks in the guide plate, etc.) and hinder transportation.

The present invention has been made in view of the above problems, and even if a medium having a low rigidity in a direction orthogonal to the medium surface (out-of-plane direction) is cut, a good linearity is obtained at the cut end. The purpose is to be able to. Further, even if the medium to be cut is charged with static electricity at the stage of transportation, it is also an object to remove the static electricity immediately so that problems such as defective transportation due to static electricity do not occur.

[0012]

SUMMARY OF THE INVENTION To achieve the above object, the present invention is a cutter device as described above, wherein a medium to be cut is pressed and fixed in the vicinity of a cutting position by a movable blade and a fixed blade. The member and the pressing member are retracted to the retracted position when the medium is conveyed to the cutting position, and the pressing member is moved to the position where the medium is pressed and fixed when the medium is conveyed to the cutting position and is cut. The holding member moving means is provided.

In the cutter device, the pressing member moving means integrally fixes the pressing member and the engaging member that is moved in the cutting direction together with the moving blade when the moving blade is moved to cut the medium. Then, when the medium is cut, it is engaged with the engaging member and is moved in conjunction with the cutting operation by the moving blade,
Engage the presser member interlocking member that moves the presser member to the position where it presses and fixes the medium, and the presser member interlocking member so that the presser member is in the retracted position when the moving blade is stopped and the medium is not cut. A biasing member that biases the member in a direction of contacting the member may be provided.

Further, in the cutter device, it is effective to make the engaging member movable to a position where it engages with the holding member interlocking member and a position where it does not engage. In the above cutter device, the pressing member moving means includes a drive source that is driven at an instructed timing, and moves the pressing member to a position for pressing and fixing the medium near the cutting position and a retracting position. It is preferable to have control means for driving the drive source of the moving means in conjunction with the cutting operation of the medium by the moving blade to move the holding member from the retracted position to the position for holding and fixing the medium.

Furthermore, in the above cutter device,
When the medium to be cut is conveyed to the cutting position by the movable blade and the fixed blade, the medium is advanced between the holding member and the medium so that the medium does not come into contact with the holding member and the holding member is separated from the medium. It is advisable to provide an isolation guide member that guides the medium in the transport direction, and when the medium is transported to the cutting position and is cut, retreats in conjunction with the cutting operation by the moving blade to release the isolation of the pressing member.

Further, in the above cutter device, it is preferable to provide a pressing pressure adjusting mechanism for adjusting the pressing pressure with which the pressing member presses and fixes the medium. Further, in the above cutter device, it is effective to form at least a portion of the pressing member that is in contact with the medium with a conductive elastic material such as felt, urethane foam, rubber or sponge having conductivity.

[0017]

According to the cutter device thus constructed, when the medium conveyed to the cutting position is cut, the holding member moving means moves the holding member to hold the medium near the cutting position and fix it. Even when cutting a medium having low rigidity in the direction orthogonal to the medium surface (out-of-plane direction), good linearity can be obtained at the cut end. Further, when the medium is conveyed to the cutting position, the pressing member moving means retracts the pressing member to the retracted position, so that there is no hindrance to the conveyance of the medium.

If the pressing member moving means is provided with the above-mentioned engaging member, pressing member interlocking member and urging member, the moving blade is moved to cut the medium. , The engaging member also moves along with the movement of the movable blade, which engages with the holding member interlocking member and moves the holding member interlocking member to the position where the holding member presses and fixes the medium. The movement of the pressing member can be interlocked with the movement of the movable blade without providing a control system for moving the member along with the movement of the movable blade.

Further, if the engaging member can be moved to a position where it engages with the pressing member interlocking member and a position where it does not engage, it has high rigidity and it is necessary to press and fix the medium at the time of cutting. In the case of cutting a medium that does not have a holding member, the engaging member can be moved to a position where it does not engage with the holding member interlocking member.

Further, the holding member moving means moves the holding member to a position for holding and fixing the medium near the cutting position and a retracted position, and the holding member for holding and fixing the medium from the retracted position. And a control means for moving the medium to a position where the medium is cut, the driving source of the moving means is selectively driven according to the type of the medium to be cut, and the pressing member is fixed from the retracted position by pressing the medium. It can be moved arbitrarily.

Further, according to the cutter device provided with the separating guide member, even if the charged medium is conveyed to a position where the holding member is present, the separating guide member separates the holding member and the medium when the medium is conveyed to the cutting position. The pressing member separates from the medium by advancing during the period and guides the medium in the conveyance direction, so that the pressing member may be electrostatically attached to the pressing member even when the conveyed medium is charged. Can be prevented.

Further, if a pressing pressure adjusting mechanism for adjusting the pressing pressure for pressing and fixing the medium by the pressing member is provided, the pressing pressure can be adjusted according to the type of medium used by the mechanism. It is possible to prevent problems such as contamination of the medium that are likely to occur when an excessive pressing pressure is applied to the medium.

Further, at least the portion of the pressing member which is in contact with the medium has a conductive felt, urethane foam,
If it is made of a conductive elastic material such as rubber or sponge, even if the medium is charged, static electricity can be removed by contacting it with the holding member, so it is possible to prevent the medium from adsorbing to the transport surface such as the guide plate. And can be transported smoothly.

Therefore, the cutter device 21 for cutting the medium 22 to be cut such as a continuous strip of paper located between them is provided.

In the cutter device 21, the medium 22 to be cut into a predetermined length after printing has a rigidity in the Z direction (out-of-plane direction), which is relatively orthogonal to the medium surface of thin paper, cloth label or the like. Even in the case of a low medium, the medium 22 to be cut is located near the cutting position by the round blade 35 and the fixed blade 36 (the position shown in FIG. 2B) so that the cutting can be performed accurately with good linearity. A pressing member 37 for pressing and fixing is provided.

In the cutter device 21, the pressing member 37 is interlocked with the movement of the round blade 35 of the cutter device 21 to press the medium 22 near the cutting position, the round blade 35 and the fixed blade 36.

On the right side), there is provided a conveying roller pair 23 in which the rollers rotate in pressure contact with each other, and a thermal head 24 for printing on the medium 22 is arranged on the upstream side of the conveying. The thermal head 24 is a line type thermal head, is fixed to the lower surface of the thermal head plate 25, and is pressed against the platen roller 27 by a pressure member (not shown) attached to the head frame 26. There is.

Then, the medium 22 for printing is sandwiched between the thermal head 24 and the platen roller 27 via a thermal transfer ribbon 28, and the platen roller 27 is indicated by the arrow E while the thermal head 24 selectively heats and prints.
By rotating in the direction, predetermined printing is performed on the medium 22 to be printed.

When the medium 22 is conveyed by the platen roller 27, the thermal transfer ribbon 28 is unwound from the supply ribbon shaft 29 side and printed by the thermal head 24 via the guide shaft 30 so that the thermal transfer ribbon 28 is brought into close contact with the upper surface of the medium 22. 3, tension applied to the portion used for printing by the winding shaft 31 rotating in the arrow F direction and FIG.
The ribbon peeling plate 32 separates the medium 22 from the medium 22 by the tension applied to the medium 22 by the conveying force of the conveying roller pair 23 that rotates in the arrow direction, and is wound around the winding shaft 31 via the winding guide shaft 33.

On the other hand, the printed medium 22 is sent to the cutter device 21 by the conveying roller pair 23, and the transmission or reflection type sensor (not shown) mounted on the conveying path detects the medium 22. The round blade of the cutter device 21 for each cutting timing corresponding to the cutting length of the medium 22 that is instructed based on the output signal or the data of the rotation amount of the platen roller 27 corresponding to the conveyance amount of the medium 22. The carriage 34, which rotatably holds 35 via a shaft 43, is alternately moved from the front side to the back side and from the back side to the front side in FIG. The fixed blade 36 is cut into a predetermined length.

Next, the medium 22 to be cut is set to a round blade 35.
The pressing member 37 is retracted to the retracted position when the medium 22 is conveyed to the cutting position by the fixed blade 36, and the medium 22 is pressed to the position where the medium 22 is fixed when the medium 22 is conveyed to the cutting position and cut. The pressing member moving means for moving the will be described in detail mainly with reference to FIGS. 1 (a) and 1 (b) and FIGS. 2 (a) and 2 (b).

Pressing member 37 constituting pressing member moving means
Is fixed to the lower surface of the bracket 18, and the bracket 18 has mounting surfaces having elongated holes 18a and 18b formed at both ends as shown in FIGS. 1 (a) and 1 (b), respectively. It is held by fixing screws (stepped screws) 40, 40 which are inserted into the holes 18a, 18b and fixed to the left and right spring receiving frames 47, 47 and the cutter frame 55 (see also FIG. 2). 40 in the long hole 18a,
It is movable only in the vertical direction within a range where the upper and lower hole ends of 18b abut.

The left and right spring receiving frames 47, 47
Has the lower side fastened and fixed to the cutter frame 55 by screws 53, 53. The bracket 18 is
1A, which is the moving direction of the circular blade 35, extends in the left-right direction, and a pressing member interlocking plate 38, which is a pressing member interlocking member, is integrally formed on the upper surface at a symmetrical position with respect to the center in the longitudinal direction. It is fixed to.

Further, between the left and right mounting surfaces of the bracket 18 and the cutter frame 55, the above-mentioned spring receiving frames 47, 47 are provided fixed to the cutter frame 55, respectively. Four
The compression coil springs 39, 39 are mounted between the upper surface of 7 and the lower surface near both ends of the bracket 18, respectively, and the urging force of the compression coil springs 39 pushes the bracket 18 up in a normal state (a state where no external force acts on the pressing side). Long hole 1
The lower end side of each of 8a and 18b abuts on the fixing screw 40 at the position shown in FIG.

Therefore, in this state, as shown in FIG. 2A, the pair of conveying rollers 23 conveys into the gap between the pressing member 37 and the fixed blade 36, which are in the position pushed up together with the bracket 18. The medium 22 guided by the lower guide plate 41 can be conveyed. The round blade 35 is rotatably attached to the shaft 43 via a bearing 52, and the shaft 43 is fixed to the carriage 34.

The carriage 34 plays a role of holding the circular blade 35 so as to maintain the positional relationship suitable for cutting the medium 22 with respect to the fixed blade 36, and the timing belt 42 is provided so as to penetrate both side surfaces thereof. The timing belt 42 is fixed as shown in FIGS.
Is rotated in both forward and reverse directions by a drive source (not shown), so that the circular blade 35 moves together with the carriage 34 into the fixed blade 3.
It reciprocates in the left-right direction in FIG.

The shaft 43 to which the round blade 35 is fixed is attached to the round blade 35.
A bearing 44 that is an engaging member that is moved in the cutting direction together with the round blade 35 when the medium 22 is moved to cut the medium 22.
Is rotatably attached to the pressing member interlocking plate 38, and when the round blade 35 is moved to the cutting side as shown in FIG. 1B, the lower part of the peripheral surface of the bearing 44 is a pressing member. A stepped portion 38 that is raised by one step in the central portion of the interlocking plate 38
The pressing member 37 fixed to the lower surface of the pressing member interlocking plate 38 is pressed down by contacting with c, and presses and fixes the medium 22 to be cut near the cutting position.

Therefore, the holding member interlocking plate 38 is engaged with the bearing 44 when the medium 22 is cut and is moved in association with the cutting operation by the round blade 35, so that the holding member 37 is moved to the medium 2.
Press 2 and move it to the position where it is fixed.

Further, the pressing member interlocking plate 38 is the round blade 3
When the member 5 is stopped at any position shown by a solid line and an imaginary line in FIG. 1A and does not cut the medium 22, the pressing member 37 is moved to the retracted position (the position shown in the same figure). The upper surface is urged by springs 39, 39, which are urging members, in a direction (upward) in contact with the bearing 44.

Therefore, in this embodiment, the bracket 18, the pressing member interlocking plate 38, the bearing 44 attached to the shaft 43, and the two springs 39, 39 serve to move the medium by the movable blade and the fixed blade. It corresponds to a pressing member moving means that moves the pressing member to the retracted position when it is conveyed to the cutting position, and moves the pressing member to a position that presses and fixes the medium when the medium is conveyed to the cutting position and cut. .

When the cutter device 21 sequentially cuts the medium 22 conveyed to the cutting position into a predetermined length,
By rotating a cutter motor (not shown), the timing belt 42 is rotated and the carriage 34 is rotated.
Is moved from the position shown by the solid line in FIG. 1A to the position shown by the phantom line (or vice versa) along the blade edge extending in the cutting direction of the fixed blade 36.

By the movement of the carriage 34, the bearing 44, which is rotatably attached to the shaft 43 fixed thereto, moves to the inclined surface portion 38a of the pressing member interlocking plate 38.
When it reaches, the pressing member interlocking plate 38 is pressed down by the bearing 44 rollingly contacted therewith, and the pressing member 37 fixed to the lower surface of the pressing member interlocking plate 38 is pressed down.

Therefore, the medium 22 which has been conveyed to the cutting position and is about to be cut is fixed by the pressing member 37 near the cutting position as shown in FIG. It is pressed against the upper surface of the blade 36 and is cut between the fixed blade 36 and the circular blade 35 which moves leftward in FIG. 1B.

Then, the medium 22 by the pressing member 37
The pressing is performed until the bearing 44 passes through the inclined surface 38b of the pressing member interlocking plate 38 as shown by the phantom line in FIG.

As described above, when the medium 22 is cut by the round blade 35 and the fixed blade 36, the cutter device 21 presses the medium 22 to be cut by the pressing member 37 in the vicinity of the cutting position and fixes it. Since the cutting is carried out while the cutting is performed, a force for deforming the medium 22 in the Z direction (out-of-plane direction) shown by the arrow in FIG. Even if is applied, the deformation can be suppressed.

Therefore, the cutting line of the medium 22 cut by the cutter device 21 has a good linearity. By the way, when a cloth label or the like is used as the medium 22 to be printed, the thermal transfer ribbon 28 adheres to the medium 22 when the medium 22 is heated under pressure by the thermal head 24 in the printing process, and then the thermal transfer is performed. The medium 22 is often charged with static electricity when the ribbon 28 is peeled off by the ribbon peeling plate 32.

Since the medium to be printed such as the cloth label has a relatively low rigidity in the direction orthogonal to the medium surface (Z direction shown by the arrow in FIG. 3), the medium as shown in FIG. It is good when the deformation of the medium 22 in the above-described rigidity direction is suppressed by guiding with the guide plate 45 and the lower guide plate 41, but when the medium 22 passes through the upper guide plate 45, the deformation cannot be suppressed. Thus, as shown in the figure, the portion of the upper guide plate 45 on the tip side is easily deformed.

In this case, when the medium 22 comes into contact with the pressing member 37 or a member in the vicinity thereof, the contact surface of the pressing member 37 or the like is formed of a material which is relatively easily adhered by static electricity. When it is being used, it will come into close contact therewith, which will hinder the transportation.

Therefore, the contact portion of the holding member 37 or a member located near the holding member 37 that may come into contact with the medium 22 with the medium 22 is made of a conductive material such as felt, urethane foam, rubber or sponge. If you use elastic material alone or combine two or more kinds of these materials and body-ground it to the body made of conductor,
Even if the medium 22 is charged as described above, the static electricity can be removed when the medium 22 comes into contact with the conductive elastic material such as the pressing member 37, so that the medium 22 can always be smoothly transported.

Further, a self-discharge type static eliminator 54 such as a static eliminator brush as shown in FIG. 5 is provided on the upstream side of the pressing member 37 in the medium conveyance, and the longitudinal direction thereof is shown by an arrow A as shown in FIG. When the medium 22 conveyed in a direction orthogonal to the conveying direction (in the front and rear directions in the figure) is conveyed, the medium 22 conveyed in a charged state is more effective because its static elimination brush removes static electricity. .

Next, a different embodiment of the cutter device according to the present invention will be described with reference to FIGS. 7 is a perspective view showing the cutter device, FIG. 8 is a schematic view showing a state in which the holding member is separated from the medium by the separating guide plate which is a characteristic part of the cutter device, and FIG. 9 is a view showing the holding member by the separating guide plate. 10 and 11 are side views showing the state before and during cutting of the medium by the cutter device, respectively, and FIG. 12 is a control system of a printing device equipped with the cutter device. 3 is a schematic block diagram showing only a main part of FIG.

The isolation guide plate 46 is used for the medium 2 to be cut.
When the sheet 2 is conveyed to the cutting position by the round blade 35 and the fixed blade 36, the medium 22 is advanced between the holding member 37 and the medium 22 so that the medium 22 does not contact the holding member 37.
7 is separated from the medium 22 to guide the medium 22 in the conveying direction, and when the medium 22 is conveyed to the cutting position and is cut, it is retracted in association with the cutting operation by the movement of the round blade 35 and the pressing member. Release the isolation of 37.

As shown in FIG. 7, the isolation guide plate 46 is made of a plate material extending along the bracket 58 in substantially the same length, and the spring receivers 46a and 46b are provided at both ends on the downstream side of the conveyance. The spring receiver 46a.
And 46b, a separating plate portion 46c for separating the pressing member 37 from the medium 22 is formed.

At both ends of the flat guide surface of the isolation guide plate 46, elongated holes 46 are formed along the medium transport direction.
d and 46e are formed, and screws (stepped screws) 5 are inserted in each long hole.
9, 59 (not shown on the side of the long hole 46d) are inserted, and the respective screws 59 are fastened and fixed to the lower guide plate 41 (FIG. 10), and the isolation guide plate 46 moves in the left-right direction in FIG. To the holding member 3
7 and the medium 22 to move the holding member 37 into the medium 22.
It is made movable to a position where the medium 22 is isolated from the position where the medium 22 is guided in the transport direction indicated by the arrow A, and a position where the medium 22 is retracted to release the separation of the pressing member 37 as shown in FIG.

As shown in FIG. 7, the isolation guide plate 46 is always in the direction of arrow A by the urging force of the compression coil springs 61, 61 mounted between the spring receivers 46a, 46b on both sides and the fixed portion of the apparatus. Further, compression coil springs 60, 60 are similarly mounted between both ends of the upper surface of the bracket 58 between the bracket 58 and the fixing portion of the apparatus.

Therefore, the isolation guide plate 46 has spring supports 46 on both sides at the rotating position of the cam 49 shown in FIG.
The left side of a and 46b in the same figure presses against the cams 49 and 49, respectively, and the bracket 58 also presses against the cams 49 and 49 on the undersides of both ends of the plane fixing the pressing member 37. As shown in FIG. 7, one end of the arm 57 is fixed to one end of the shaft 48 to which the cam 49 is fixed, and the other end is connected to the movable shaft 50a of the solenoid 50 via the tension coil spring 56. It is connected.

The separating plate portion 46c enters between the lower guide surface 71 and the pressing member 37 to shield the pressing member 37, and between the lower guide surface 71 and the separating guide plate 46 also serving as the upper guide surface. The medium 22 cut into pieces is smoothly conveyed.

When the medium 22 is cut, the solenoid 50 shown in FIG. 7 is operated (turned on) to rotate the arm 57 in the clockwise direction in the figure, and the cams 49, 49 on both sides are moved via the shaft 48. Rotate to the position shown in FIG. Then,
The bracket 58 is pressed downward by the biasing force of the compression coil springs 60, 60, and the pressing member 37 fixed to the lower surface presses the medium 22 conveyed to a predetermined cutting position on the lower guide surface 71. , Fix it temporarily.

Further, the spring receiver 46 of the isolation guide plate 46
Since the large eccentric portions 49a of the cams 49, 49 come into contact with the left surfaces of the a, 46b, respectively, the isolation guide plate 46 is moved to the right in FIG. 9 against the biasing force of the compression coil springs 61, 61. The tip end side separating plate portion 46c is pulled out from between the lower guide surface 71 and the pressing member 37 to release the blocking of the pressing member 37. Therefore, the descending pressing member 37 and the separating plate portion 46c do not interfere with each other.

Then, in this embodiment, the medium 2 to be cut is used.
The pressing member moving means for pressing 2 near the cutting position at the time of cutting is provided with a solenoid 50 which is a drive source driven at an instructed timing, and a position for fixing the pressing member 37 by pressing the medium near the cutting position. It has a moving means for moving it to the retracted position, and the moving means includes the solenoid 50, the cam 49, the bracket 58, and the compression coil spring 6.
It consists of 0 mag.

Further, the pressing member moving means presses the medium 50 from the retracted position by driving the solenoid 50 of the moving means in association with the cutting operation of the medium 22 by the round blade 35 which is the moving blade. Main control unit 8 shown in FIG. 12 functioning as a control means for moving to a fixed position.
It also has 0.

The main controller 80 is composed of a microcomputer, and the sensors 81 and 82 (both are transmission type photosensors) whose detectors are turned on and off by the movement of the carriage 34 shown in FIG. A selection signal to be used when selecting whether to input a detection signal from the control panel, which is provided on an operation panel (not shown), and which presses the medium according to the type of the medium to be used by operating the solenoid 50. From the key,
When it is pressed, it inputs the solenoid drive selection signal.

The main controller 80 sends and receives signals to and from the print controller 83, and the print controller 8
3 outputs to the thermal head driver section 84 a signal for printing based on the print information sent from the main control section 80.

The main controller 80 also sends and receives signals to and from the cutter controller 85, and the cutter controller 85 sends a signal for driving the cutter motor 86 for moving the carriage 34 of the cutter device to the cutter motor driver. It is output to the section 87.

Further, the main control unit 80 also sends and receives signals to and from the transport control unit 88 which drives and controls various transport systems of the printing apparatus, and the transport control unit 88 operates the transport motor 89. The signal is output to the carry motor driver unit 91 to drive the carry motor 89.

Then, when the main controller 80 inputs a detection signal for detecting the carriage 34 from the sensor 81 while inputting the solenoid drive selection signal described above, it turns on the solenoid 50 to the solenoid driver 92. When the detection signal for detecting the carriage 34 is input from the sensor 82, the control for turning off the solenoid 50 is performed.

The solenoid 50 is turned on in conjunction with the cutting operation of the medium by the round blade 35 to move the holding member 37 from the retracted position to the position for holding and fixing the medium 22, and after cutting the medium 22, the solenoid is cut off. To control the pressing member 37 to be returned to the retracted position by turning off 50, for example, the sensor 81 is set to the slope 3 of the pressing member interlocking plate 38 shown in FIG.
8a is arranged at a position where the carriage 34 can be detected when the bearing 44 reaches the position corresponding to 8a.
Is arranged at a position where the carriage 34 can be detected when the bearing 44 reaches the position corresponding to the slope 38b of the pressing member interlocking plate 38, and the carriage 34 together with the round blade 35 has a home position on the left side in FIG. The main controller 80 controls so that the solenoid 50 is turned on when the sensor 81 first detects the carriage 34 after moving in the cutting direction, and the solenoid 50 is turned off when the sensor 82 next detects the carriage 34. Can be done by doing.

According to this embodiment, the on / off operation of the solenoid 50 can be selectively performed depending on the type of the medium to be cut, so that the medium to be cut is in the direction perpendicular to the medium surface (see FIG. 3). When it is not necessary to press and fix it near the cutting position at the time of cutting, such as when the rigidity in the Z direction) is high, the medium is cut without turning on the solenoid 50. The pressing operation of the medium can be selectively performed according to the type of the medium.

Further, when the medium 22 is conveyed to the cutting position, the separating plate portion 46c of the separating guide plate 46 enters between the lower guide surface 71 and the pressing member 37 as shown in FIG. Since it is in the shielded state, even if the medium 22 sent to the cutter device after being printed is charged, it is possible to reliably prevent the medium 22 from sticking to the pressing member 37, so that it can be smoothed. Can be transported to.

13 to 15 show an embodiment of a cutter device provided with a mechanism for moving the separating guide plate to the position for separating the pressing member and the position for releasing the separation by interlocking with the movement of the round blade. The same reference numerals are given to portions corresponding to those in FIGS. In this cutter device, the separating guide plate 46 'has an upper flat surface portion 46f having a substantially U-shaped side surface with respect to the separating guide plate 46 according to the embodiment shown in FIG.

2 is a schematic view showing a state in which the switching mechanism is set on the operation side for pressing the medium, and FIG. 19 is a schematic view showing a state in which the mechanism is set on the release side. Is attached.

In contrast to the embodiment shown in FIGS. 1 and 2, this embodiment has a switching mechanism in which the bearing 44 is movable between a position where it engages with the holding member interlocking plate 38 and a position where it does not engage. However, the only difference is that the bearing 44 mounted on the shaft 43 supporting the round blade 35 can be changed in position along the axial direction.

That is, as shown in FIG. 17, a bearing 44 is fitted on a shaft 43 so as to be movable in the axial direction of arrow K, and a through hole 43a is formed in the shaft 43 in the radial direction. A ball plunger 73 is fitted in and fixed therein, and a ball 73a at its tip is projected from the outer peripheral surface of the shaft 43.

As shown by the solid line of the bearing 44 in the figure, it is the ball 73a of the ball plunger 73.
In the figure, a retaining ring 72 is fitted in the annular groove at the tip of the shaft 43 so that the retaining ring 72 is positioned so as to be in contact with or close to the right side.

Further, from that position, the bearing 44 is shown in FIG.

If it is set to a position that does not engage with the pressing member interlocking plate 38 as shown in FIG. 19 when it is set to the position indicated by the phantom line in FIG. 7, by selectively selecting the position of the bearing 44, It is possible to perform the operation of pressing the medium 22 near the cutting position by the pressing member 37 in conjunction with the cutting operation of the medium by the round blade 35, or to cancel the interlocking operation.

In each of the above embodiments, the case where the movable blade is a rotating round blade has been described, but a sharp blade is moved along the fixed blade at an angle inclined with respect to the surface of the medium to be cut. The present invention can be similarly applied to a cutter device including a non-rotating movable blade that cuts and cuts.

[0094]

As described above, the cutter device according to the present invention has the following effects. According to the cutter device of claim 1, even when the moving blade is about to deform the medium in the direction orthogonal to the medium surface due to the cutting resistance when the medium is cut, the holding member is cut when the medium is cut. Since the deformation is regulated by pressing and fixing the medium near the cutting position, even when cutting a medium with low rigidity that easily deforms in the above direction, the cut has excellent linearity. Good cutting can be performed.

According to the cutter device of the second aspect, the pressing operation of the medium by the pressing member can be linked with the cutting operation by the moving blade, so that the control system of the apparatus can newly set the timing of the cutting operation of the pressing member. Since it is not necessary to add a control system for moving together, or an actuator for moving the pressing member, it is possible to make the control system simple and inexpensive because the actuator is unnecessary.

According to the cutter device of the third aspect, the pressing operation of the pressing member can be selectively performed according to the type of the medium by a simple operation of changing the position of the engaging member. When using a medium having high rigidity that does not need to be fixed by the holding member, it is possible to freely select an operation suitable for the type of medium used, such as not operating the holding member.

According to the cutter device of the fourth aspect, the drive source of the moving means is driven in conjunction with the cutting operation of the medium by the moving blade to move the holding member from the retracted position to the position where the medium is pressed and fixed. Since the operation can be selectively performed according to the type of medium to be cut, in the case of a medium that does not need to be fixed at the time of cutting, do not operate the drive source, and perform an operation that is suitable for the medium to be used. You can

According to the cutter device of claim 5, sticking of the charged medium to the pressing member due to static electricity can be prevented, so that the medium after printing can be conveyed smoothly.

According to the cutter device of claim 6, by adjusting the pressing pressure of the pressing member to the medium, the pressing pressure can be set to the optimum pressing pressure according to the type of the medium to be used. It is possible to eliminate problems such as stains on the medium caused by the above.

According to the cutter device of claim 7, it is possible to efficiently remove static electricity from the charged medium, prevent problems such as sticking to the transport surface due to static electricity of the medium, and perform smooth transport. it can.
