Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer with a cutter for cutting a part of recording paper, and more particularly to a printer having a chip storage portion for storing cut chips.

[0002]

2. Description of the Related Art A color thermal printer is known in which a thermal head is used to heat a color thermal recording paper to record a full-color image in a three-color frame sequence. In the color thermal printer, the color thermal recording paper is reciprocated while being nipped by the conveying rollers. The thermal head is arranged at a position close to the transport roller, but it is not possible to record an image on a portion corresponding to the distance between the transport roller and the thermal head. Further, the thermal head nips the color thermosensitive recording paper with the platen roller, but when the platen roller is heated by the part of the thermal head protruding from the color thermosensitive recording paper, the platen roller is thermally deformed, The service life may deteriorate. Therefore, a margin is left on the edge of the color thermosensitive recording paper, and an image is recorded inside the margin. For these reasons, a margin is formed at the end of the printed color thermosensitive recording paper.

Recently, since the number of users who desire a print without a margin is increasing, for example, Japanese Patent Laid-Open No. 2000-16287 is used.
A printer with a cutter, such as the printer described in Japanese Patent Publication No. 7, which has a cutter for cutting a margin of a printed color thermosensitive recording paper is well known. In the printer with a cutter, a scrap box is provided below the cutter as a chip storage unit for storing cut chips (margins). This prevents chips from scattering in the printer. When chips are accumulated in the waste box, the waste box is removed from the printer body and the chips are discarded.

[0004]

However, in the waste box, since the places where the dropped chips are accumulated are concentrated at a specific position, the waste box has a portion where the chips are accumulated and an empty portion. There was a problem that it was divided and storage efficiency was poor. If the storage efficiency is poor, the waste box maintenance work is frequently performed, such as discarding the chips in the waste box or leveling the chips accumulated in the waste box even though the number of prints is small. The need arises.

The printer with a cutter according to the present invention has been made in consideration of the above problems, and an object thereof is to improve the storage efficiency of the chip storage portion.

[0006]

In order to achieve the above object, a printer with a cutter according to the present invention is a printer with a cutter provided with a cutter for cutting a part of a recording paper, in which chips cut by the cutter are removed. A chip accommodating part for accommodating, a chip conveying means arranged below the cutter, for conveying the fallen chips to the chip accommodating part, and a part of the chip accumulated on a specific portion in the chip accommodating part by the conveying. A chip pushing means for pushing the chip into an empty space in the chip storage portion is provided.

As the chip conveying means and the chip pushing means, a belt mechanism is provided between the cutter and a chip accommodating portion arranged below the cutter, and the belt mechanism is a first mechanism for conveying the dropped chips. A belt having a surface and a second surface that faces the opening of the chip storage portion and presses a part of the chip into the empty space by contacting the chip accumulated in the specific portion, and the belt. By disposing each of the drive rollers so that the first surface and the second surface form a substantially V-shape, a chip is scraped from the first surface. While tilting from the falling position toward the chip storage part, on the other hand,
The second surface is brought close to the specific portion in the chip storage unit.

A blower fan is provided for sending air from the cutter to the chip conveying means so that the chips cut by the cutter are directed to the chip conveying means.

A scrap amount detecting means for detecting that the scrap storage portion is full is provided. The waste amount detecting means includes, for example, a switch or a sensor that transmits a detection signal to the controller, and a switching member for operating the switch or the sensor, and at least a part of the switching member is the chip storage. It is arranged so as to be located inside the unit, and when the chip storage unit is full, it is displaced by the pressure from the chips to operate the switch or sensor.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 and 2, a recording paper roll 11 is set in a color thermal printer 10 in a paper feed magazine 12. The recording paper roll 11 is formed by winding a long color thermosensitive recording paper 13 into a roll shape. The color thermosensitive recording paper 13 is a well-known color thermosensitive recording paper composed of three thermosensitive coloring layers of cyan, magenta and yellow, and has an emission peak wavelength of 420 nm.
By irradiating the fixing light for yellow in the vicinity, the coloring ability of the yellow thermosensitive coloring layer disappears, and the emission peak wavelength is 365n.
By irradiating the magenta fixing light near m, the coloring ability of the magenta thermosensitive coloring layer disappears.

A lid 17 is provided on the front surface of the main body 16 of the color thermal printer 10 so as to be openable and closable at a lower portion thereof. The paper feed magazine 12 is set by opening the lid 17. A paper feed roller 18 is provided in the paper feed magazine 12, and the color thermosensitive recording paper 13 is pulled out onto the transport path by the paper feed roller 18. The color thermal printer 10 prints an image on the color thermal recording paper 13 that has been pulled out, and after printing, cuts a marginal portion at the tip of the color thermal recording paper 13 to print a so-called borderless print 2.
2 is ejected.

A front opening 23 is formed in the center of the front surface of the main body 16. The front opening 23 is a guide member 24.
Is divided into an upper part and a lower part. Guide member 24
Is for guiding the print 22, and the print 22 is discharged from above the guide member 24. A waste box storage space 26 is provided below the guide member 24. The waste box 27 is a chip accommodating portion for accommodating the cut chips 28, and is detachably set in the waste box accommodation space 26. When discarding the chips 28, the scrap box 27 is pulled out. A handle 27a is provided on the front surface of the waste box 27 so that it can be easily pulled out. This handle 27a is
It also functions as a guide plate for guiding the discharged print 22.

An operation panel 31 is provided on the main body 16 above the front opening 23. Operation panel 31
Inside, a power switch, a print start button, etc. are arranged. In addition to the power lamp, the operation panel 31 is provided with various warning lamps 31a. These warning lamps 31a include a lamp for notifying that the paper is out, a lamp for notifying that a paper jam has occurred, and a lamp for notifying that the chips 28 in the waste box 27 are full.

A print space accommodating space 35 in the main body 16
On the conveyance path, a pair of conveyance rollers 36 for conveying the color thermosensitive recording paper 13, a thermal head 37, and optical fixing devices 38, 39 for yellow and magenta are arranged. The thermal recording and optical fixing of the color thermosensitive recording paper 13 are performed while being reciprocally conveyed by each conveying roller pair 36.

As is well known, the thermal head 37 is provided with a heating element array in which a large number of heating elements are arranged in the main scanning direction. The heating element array is pressed against the color thermosensitive recording paper 13 to perform thermal recording. A platen roller 41 that supports the color thermosensitive recording paper 13 from the back side is arranged at a position facing the thermal head 37.

The yellow optical fixing device 38 irradiates the color thermosensitive recording paper 13 after the yellow image is thermally recorded on the yellow thermosensitive coloring layer with 420 nm yellow fixing light to develop the yellow thermosensitive coloring layer. Ability is lost. In addition, the magenta optical fixing device 39 is a color thermosensitive recording paper 1 after thermal recording of a magenta image on the magenta thermosensitive coloring layer.
3 is irradiated with a fixing light for magenta of 365 nm to eliminate the coloring ability of the magenta thermosensitive coloring layer.

The cutter 21 includes a movable blade 21a and a fixed blade 21.
A shearing cutter composed of b and the longitudinal direction thereof is arranged along the width direction of the color thermosensitive recording paper 13. The cutter 21 cuts off the marginal portion at the tip of the color thermosensitive recording paper 13 on which printing has been stopped. afterwards,
The color thermosensitive recording paper 13 is conveyed by a predetermined amount, and the recorded portion is cut into a sheet in a state where the leading end thereof is nipped by the paper discharge roller pair 43. The paper discharge roller pair 43 discharges the cut sheet as a print 22 from the front opening 23.

Below the cutter 21, a frame member 46 is arranged. The frame member 46 is formed with a drop opening 46a through which the cut chips 28 fall. This drop port 4
A belt mechanism 47 is arranged between the 6a and the waste box 27. The belt mechanism 47 collects the dropped chips 28 from the waste box 2
Transport to 7. The waste box storage space 26 is separated from the print section storage space 35 including the transport path by the frame member 46 and the partition plate 52. This prevents the chips 28 from accidentally flowing into the space 35.

Above the cutter 21, a drop port 46 is provided.
A blower fan 53 that sends the wind toward the belt mechanism 47 through a is provided. As a result, the cut chips 28 are pushed by the wind from the blower fan 53, so that they are surely dropped onto the belt mechanism 47. Further, this air flow also functions as an air curtain that prevents dust and the like generated during cutting from flowing into the print unit accommodation space 35. Further, a partition plate 56 is also provided beside the blower fan 53. The partition plate 56 prevents the wind from the blower fan 53 from flowing into the print unit accommodation space 35.

As shown in FIG. 3, the belt mechanism 47 includes three belts 61 arranged side by side in the width direction of the color thermosensitive recording paper 13 and three belts 61 for driving the belts 61.
It consists of book drive rollers 62a, 62b, 62c. Each drive roller 62a, 62b, 62c has its longitudinal direction arranged along the width direction, and supports three belts 61 arranged in parallel. Drive rollers 62a, 62
b and 62c are driven by a belt drive motor 64, and rotate the belt 61 counterclockwise (see the arrow in the figure).

Each drive roller 62a, 62b, 62c is
The belts 61 are arranged so that their cross sections are triangular. As a result, each drive roller 62 is attached to the belt 61.
First to third surfaces 61a, 61 between a, 62b, 62c
b, 61c are formed.

The first surface 61a carries the dropped chips 28 to the waste box 27. As a result, the dropped chips 28 are retracted from the position below the cutter 21, so that the chips 28 do not accumulate under the cutter 21 and jamming occurs. Further, the first surface 61a is provided with the chips 28.
Are arranged so as to be lowered in accordance with the transport direction of.
By doing so, the chips 28 are surely inserted in the waste box 27. Chips 28 conveyed by the first surface 61a
Are dropped and accumulated in the front of the waste box 27 (left side in FIG. 2).

The second surface 61b of each belt 61 has a waste box 2
7 is disposed at a position facing the opening 27b and covers a part of the opening 27b. The second surface 61b is
By contacting with the vicinity of the top of the pile of chips 28 accumulated in the waste box 27, a part thereof is pushed into an empty space in the waste box 27, that is, rearward (right side in FIG. 2) in the waste box 27. As a result, the chips 28 are not concentrated on a specific portion in the waste box 27, and the chips 28 are leveled in each part, so that the storage efficiency of the waste box 27 is improved.

The second surface 61b moves from the front of the waste box 27 toward the rear thereof. The second surface 61b is inclined so that its position becomes lower in the moving direction. In other words, the position facing the rear of the waste box 27 where the empty space is formed is lower than the position facing the front of the waste box 27 where the chips 28 accumulate. By doing so, the second surface 61b can be brought closer to the chips 28 accumulated in the waste box 27, and the second surface 61b and the chips 2 can be made closer to each other.
The number of parts in contact with 8 increases. That is, the pile of the accumulated chips 28 draws a ridge line such that the top thereof is located in front of the waste box 27 and becomes lower toward the rear thereof. Second side 6
By arranging 1b so as to be inclined along this ridgeline, the portion in contact with the chips 28 increases.

Further, since the second surface 61b is arranged so as to cover a part of the opening 27b of the waste box 27, it is possible to hold down the chips 28 which are likely to overflow from the opening 27b. As a result, the chips 28 in the waste box 27 are compressed and the storage efficiency is further improved.

Three drive rollers 62a, 62b, 62c
By arranging so that the first surface 61a and the second surface 61b of the belt 61 form a substantially V shape.
The above-mentioned inclination is given to each of a and 61b. In this way, one belt mechanism 47 realizes two functions, that is, a function of transporting the dropped chips to the waste box 27 and a function of pushing in the chips 28 accumulated in the waste box 27. The configuration is simplified as compared with the case where each function is realized by a separate mechanism. Further, as compared with the case where each mechanism is provided separately, the number of parts can be reduced, so that not only the increase in manufacturing cost can be suppressed but also the installation space is reduced, which contributes to downsizing of the printer.

The third surface 61c of the belt 61 faces the partition plate 52 located behind the waste box 27. Third
Since the surface 61c of the chip moves upward, if the chip 28 is sandwiched between the chip 28 and the partition plate 52, the chip 2
There is a fear that 8 flows backward toward the first surface 61a. Therefore, the third surface 61c and the partition plate 52 are arranged with a predetermined gap therebetween, so that the chips 28 are not sandwiched between them.

The partition plate 52 has chips 28 in the waste box 27.
A scrap amount detection sensor 66 for detecting the amount of the waste is provided.
As the waste amount detection sensor 66, for example, a reflection type photo sensor is used. A light projecting / receiving window 67 is formed on the back surface of the waste box 27 at a position facing the waste amount detecting sensor 66. The light emitted by the waste amount detection sensor 66 passes through the light projecting / receiving window 67 and enters the waste box 27. The entering light is reflected by the chips 28 in the waste box 27. Then, the light projecting / receiving window 67
The scrap amount detection sensor 66 receives the reflected light collected from the. The waste amount detection sensor 66 sends a signal according to the light amount level to the system controller 71 (see FIG. 4).

Since the chips 28 are accumulated from the front of the chip box 27, when the amount of the chips 28 is small, the optical path length is long and the scattering of light is large, so that the amount of light received is small. On the other hand, when the amount of the chips 28 increases, the chips 28 are accumulated even behind the waste box 27, so that the chips 28 and the light projecting / receiving window 67 approach each other.
For this reason, the optical path length is shortened and the light scattering is also reduced, so that the amount of received light increases. When the level of the amount of received light exceeds a predetermined value, the system controller 71 determines that the waste box 27 is full, turns on the warning lamp 31a, and prohibits the print processing from the next time.

FIG. 4 shows the electrical configuration of the printer. The system controller 71 controls each unit of the printer. To the system controller 71, an operation panel 31, a print unit 72, a waste amount detection sensor 66, a cutter drive unit 73, and a motor driver 74 are connected. The printing unit 72 includes a feed motor that drives the feed roller 18 and the feed roller pairs 36, a thermal head 37, and yellow and magenta optical fixing devices 38 and 39. The cutter driving unit 72 drives the cutter 21. Motor driver 74
Drives the drive motor 64.

Next, the operation of the above configuration will be described. When printing a full-color image with the color thermal printer 10, first, after the power is turned on, a print instruction is given from the operation panel 31. The paper feed roller 18 rotates, and the color thermosensitive recording paper 13 is pulled out from the recording paper roll 11 to the conveyance path. While the color thermal recording paper 13 is reciprocally moved by the pair of conveying rollers 36, the thermal head 37 and the optical fixing devices 38 and 39 for yellow and magenta perform thermal recording and optical fixing of the image of each color.

When printing is completed, the color thermosensitive recording paper 13 is sent to the cutter 21. The tip is the cutter 21
The color thermosensitive recording paper 13 is once stopped after passing. The margin is cut during this stop. The cut chips 28 pass through the drop port 46a and drop onto the first surface 61a of the belt 61. Since the blower fan 53 blows air from the cutter 21 toward the first surface 61a, the chips 28 ride on the air flow and reliably drop onto the first surface 61a.

When the cutting of the margin is completed, the color thermosensitive recording paper 13 is fed by a predetermined amount and then stopped again. During this stop, the cutter 21 separates the recorded portion into sheets. The separated sheet is ejected as a borderless print 22.

When the above print processing is repeated,
The chips 28 are accumulated in the front of the waste box 27. Chips 28
As the deposits are accumulated, the vicinity of the top of the mountain comes into contact with the second surface 61b of the belt 61. The second surface 61b is the waste box 2
Since it moves toward the rear of the chip 7, a part of the chip 28 is pushed into an empty space (rear inside the scrap box 27). Further, when the chips 28 are accumulated, the chips 28 are likely to overflow from the scrap box 27. However, the chips 28 are not pressed by the second surface 61b and do not overflow from the chip box 27.

Due to the action of the second surface 61b, the waste box 2
Chips 28 also accumulate in the rear of the inside of 7. Eventually, the light projecting / receiving window 67 is covered with the chips 28. As a result, the level of the amount of light received by the waste amount detection sensor 66 increases. When the signal level of the waste amount detection sensor 66 exceeds a predetermined value, the system controller 71 determines that the waste amount is full,
The warning lamp 31a is turned on and the printing process from the next time is prohibited.

By turning on the warning lamp 31a, the waste box 27
The user is notified that the is full. The user pulls out the waste box 27 and discards the chips 28. Since the storage efficiency of the waste box 27 is improved by the action of the belt mechanism 47, the number of times of this discarding work can be reduced as compared with the conventional example.

In the above embodiment, the third surface of the belt,
A space is provided between the partition plate and the chips to prevent the chips from flowing back to the first surface. However, as shown in FIG.
A tongue piece 81a protruding between the belts 61 may be provided in a part of the belt 1, and the backflow of the chips 28 may be prevented by the tongue piece 81a. By doing so, the space between the belt 61 and the partition plate 52 can be narrowed, so that the waste box housing space 2
The depth of 6 can be shortened. The same members as those in the above embodiment are designated by the same reference numerals.

Further, in this embodiment, the scrap box is provided with the backflow preventing tongues, but the partition plate is provided with the tongues protruding in the horizontal direction and arranged between the belts. Thus, backflow of chips may be prevented.

Further, like the belt mechanism 83 shown in FIG. 6, in addition to the three driving rollers 62a, 62b and 62c, a driving roller 62d is added so that the portion where the belt 61 and the partition plate 52 face each other. You may make it protrude forward and make a space | interval with the partition plate 52.

Further, in the above embodiment, the chips are conveyed and the chips are pushed in using the two surfaces of one belt. However, like the belt mechanism 86 shown in FIG. Belt 87 and belt 88 for pushing chips
May be provided respectively. The belts 87, 88 are alternately arranged, and the three drive rollers 62a, 62b,
It is supported by 62c. In this embodiment, the upper surface of the chip conveying belt 87 is the first surface, and the lower surface of the chip pushing belt 88 is the second surface. Even in this case, the number of belts is increased by just a few, and therefore the component cost is not significantly increased.

Further, in the above-described embodiment, an example in which a plurality of belts having a width narrower than that of the color thermosensitive recording paper is used is explained. However, a belt having a width approximately the same as the width of the color thermosensitive recording paper is used. May be used. Also, although an example using three or four drive rollers in the belt mechanism has been described,
The number of drive rollers may be more than this.

Further, in the above-described embodiment, the reflection type photosensor is used as the dust amount detecting means to irradiate the inside of the dust box with light, and the dust box is full based on the light amount level of the reflected light. However, there are various other methods for detecting the amount of waste, and any method may be used.

FIG. 8 shows another example of the method for detecting the amount of waste. The waste amount detecting means includes a switching member 91 and a photo interrupter 92. Switching member 91
Has a substantially fan shape, and is arranged behind the second surface 61 b of the belt 61. The switching member 91 includes the shaft 9
3 is provided so as to be swingable, and swings between a first position (initial position) shown by a solid line in FIG. 8 and a second position shown by a dotted line.

A notch 94a is formed on the back surface of the waste box 94. One end surface 91a of the switching member 91
When the scrap box 94 is set, the scrap box enters the scrap box 94 through the notch 94 and is located at the rear portion thereof. A tongue piece 96 is provided on the other end surface 91b. This tongue 96
Is projected from the opening 95a formed in the partition plate 95 to the rear of the partition plate 95, and functions as an operating piece that operates the photo interrupter 92 arranged behind the partition plate 95.

The second surface 61b allows the chips 28 to move into the scrap box 94.
When pushed into the rear portion of the, the chip 28 pushes the end surface 91b of the switching member 91 to swing the switching member 91 toward the second position. Scrap box 94
When the chips are full of chips 28, the switching member 91 reaches the second position, and the tongue piece 96 enters between the light projecting portion and the light receiving portion of the photo interrupter 92. When the tongue piece 96 blocks the optical path between the light projecting unit and the light receiving unit, the photo interrupter 92 operates and sends a detection signal to the system controller 71. The system controller 71 determines that the waste box 94 is full based on this detection signal.

In this example, a substantially fan-shaped member is used as the switching member, but of course other shapes may be used. For example, a pressed portion that receives pressure from chips,
The photo interrupter may be configured separately from the actuation unit for actuating the photo interrupter, and may be interlocked with each other. Further, in this example, the photo interrupter is used, but a micro switch may be provided instead and the switching member may be operated.

Further, in this example, a shutter 98 is provided above the frame member 46. The shutter 98 is for preventing jamming of the color thermosensitive recording paper 13. That is, the color thermosensitive recording paper 13 pulled out from the recording paper roll 11 has a curl. Since the drop port 46a is located in the vicinity of the passage of the color thermosensitive recording paper 13, the leading end of the recorded portion to be the print 22 does not go to the paper discharge roller pair 43 but accidentally enters the drop port 46a. There is a risk.

The shutter 98 is swingably provided between a closed position for closing the drop port 46a and an open position for opening the drop port 46a. The shutter 98 moves to the open position when cutting a margin, and moves to the closed position when cutting a recorded portion into a sheet. As a result, the drop port 46a is covered to prevent jamming.

Although an example of a printer using a recording paper roll has been described, a printer having a cutter that cuts a margin of the recording paper by using the recording paper that has been cut into a predetermined size may be used.

Further, as the cutter for cutting the margin, the so-called guillotine cutter, which is composed of the fixed blade and the movable blade and lowers the movable blade to cut the recording paper, has been described as an example. For example, a cutter including a fixed blade extending in the width direction of the recording paper and a disc blade that reciprocates along the fixed blade between an initial position and a cutting end position may be used.

In the above embodiment, a color thermal printer is shown as an example, but of course, any type of printer having a cutter for cutting a margin, for example, a thermal transfer printer,
It is also applicable to inkjet printers, laser printers, and the like. The cutter may cut off not only the margin at the front end of the recording paper but also the margin at the rear end together with the margin at the front end. Furthermore, the present invention can be applied not only to the margin but also to cutting off a part of the recording paper.

[0052]

As described in detail above, the present invention is
The printer with a cutter includes a chip storage unit that stores chips cut by the cutter, a chip transport unit that is disposed below the cutter and that transports the dropped chips to the chip storage unit, and the inside of the chip storage unit by the transport. Since the chip pushing-in means for pushing a part of the chips accumulated in the specific portion of the chip into the empty space in the chip storing portion is provided, the efficiency of storing the chips can be improved. As a result, the number of maintenance work such as discarding chips is reduced and the work load is reduced.

Further, since the belt mechanism is used as the chip conveying means and the chip pushing means, the structure can be simplified.

Further, since the blower fan for blowing air from the cutter toward the chip conveying means is provided, the chips can be surely dropped.
