Abstract

PURPOSE:To prevent a recording sheet from dropping off a transport device by providing a sheet holding device for preventing a cut recording sheet from dropping off the transport device. CONSTITUTION:It is interpreted whether a recording sheet should be cut, and if the sheet 1 is not to be cut, data is recorded in a following line, and if the sheet 1 is to be cut, the recording sheet 1 is held so that it does not drop off a pair of feed rollers 3a1, 3a2. That is, a cutter 6 is driven toe cut the recording sheet 1 after a feed clutch 3e is switched ON. If the feed clutch 3e is switched ON, the rotating load of the feed rollers 3a1, 3a2 becomes heavy. For this reason, the sheet 1 is securely held by the paired feed rollers 3a1, 3a2 and therefore, never drops off, even if a downward reaction/occur on the sheet 1 when it is cut.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a recording apparatus that prevents a recording sheet from falling off a conveying means due to reaction when cutting the recording sheet.

<Prior Art> Today, printers, facsimile machines, and the like are widely used in offices and the like, and various recording devices for outputting input information have also been developed. Among such recording devices, some use a so-called roll sheet in which a long recording sheet is wound into a roll.

For example, as shown in FIG. 12, the recording device transports a rolled sheet 50 by sandwiching it between a pair of feeding rollers 51 and a pair of conveying rollers 52, performs a predetermined recording using a recording means 53, and then cuts the sheet from the trailing edge of the image using a cutter 54. 50 is generally cut and discharged by a pair of discharge rollers 55.

<Problems to be Solved by the Invention> However, when the cutter 54 cuts the sheet, the recording sheet 50 is in a state of being discharged by the pair of discharge rollers, so that tension is applied to the sheet. When the force cutter 54 is driven to cut the recording sheet 50 in this state, a downward reaction occurs in the recording sheet 50. At this time, if a sheet with a slippery surface or a heavy sheet is used as the recording sheet 50, the reaction may cause the recording sheet 50 to
It is conceivable that the 0 may fall off from the pair of feeding rollers 51 and fall down.

If the recording sheet 50 falls off the pair of feeding rollers 51, the sheet 50 cannot be conveyed during the next recording.

In order to prevent the above-mentioned falling off, the pressure contact force of the pair of feed rollers 51 may be set strong, but if this pressure contact force is set strong, the rotational load of the pair of feed rollers 51 becomes large, and the recording sheet 50 may slip when the sheet is conveyed. , or the motor for rotating the pair of feed rollers 51 must be made larger.The object of the present invention is to solve the above-mentioned conventional problems and to securely hold a sheet when cutting the sheet. In this way, it is an object of the present invention to provide a recording device that can prevent recording sheets from falling off from conveyance means.

<Means for solving the problems> Representative means according to the present invention for solving the above problems are as follows:
A sheet conveying means for conveying a recording sheet, a recording means for recording on the recording sheet, a cutting means for cutting the recording sheet, and the recording sheet cut by the cutting means falls off from the conveying means. The present invention is characterized in that it is provided with a sheet holding means for preventing the sheet from being damaged.

<Operation> In the above means, when cutting a sheet, the cutting means is driven while the recording sheet is held by the sheet holding means. Therefore, even if a reaction force is applied to the recording sheet during sheet cutting, the sheet will not fall off from the conveyance means.

<Embodiment> Next, an embodiment of the present invention in which the above means is applied to a serial type recording device will be described.

[First example]

FIG. 1 is an overall schematic explanatory diagram of the recording apparatus, and FIG. 2 is a perspective explanatory diagram of the main parts of the recording apparatus.

(Overall Wi-Fi) First, to explain the overall configuration of the device, a long recording sheet 1 is wound into a roll, and a roll holder 2
is housed in. The recording sheet 1 is configured to be conveyed upward by a sheet conveying means 3.

Further, a suction means 4 is disposed on one side of the transport path of the recording sheet 1, and a recording means 5 is disposed on the other side so as to face the suction means 4. The recording sheet 1 thus conveyed is sucked by the suction means 4, and is conveyed while being spaced from the recording means 5 at a constant distance. Then, in synchronization with this conveyance, the recording means 5 is driven to perform predetermined recording, and the image is cut from the trailing edge by a cutter 6 serving as a sheet cutting means, and is ejected from the apparatus from an ejection lower. .

Furthermore, in this embodiment, by increasing the rotational load of the conveying means 3 as a sheet holding means only when cutting the sheet,
It is configured to hold a recording sheet 1.

Next, the configuration of each part will be specifically explained.

(Sheet conveyance means) The sheet conveyance means 3 is for conveying the recording sheet 1, and in this embodiment, as shown in FIG. Roller pairs 3b+, 3bz and discharge roller pairs 3c, 3c
The structure is such that it is transported in two steps.

The feeding roller pair 3a+, 3a+ is composed of a driving roller 3a and a driven roller 3az that is pressed against the driving roller 3a by a spring or the like (not shown) and rotates as a result.

A feed motor 3d is connected to the drive roller 3a+ via a feed latch 3e. The feeding latch 3e connects the feeding motor 3d and the drive roller 3a+ when it is in the on state, and releases the connection when it is in the off state. Therefore, the feed motor 3d is driven and the clutch 3e is
When turned on, the drive roller 3a+ rotates and feeds the recording sheet 1 upward in FIG.

Further, registration roller pairs sbl, 3bZ and discharge roller pairs 3cl, 3c2 are arranged at a predetermined distance apart, and like the feeding roller pair, these also come into pressure contact with drive rollers 3b+, 3c+, respectively. It is composed of pinch rollers 3bz and 3c2, which are driven to rotate by the pinch rollers 3bz and 3c2. A registration motor 3f is connected to the drive roller 3b+ via a registration clutch 3g.

The registration clutch 3g connects the registration motor 3f and the drive roller 3b when it is in an on state, and releases the connection when it is in an off state. As a result, when the registration motor 3f is driven and the clutch 3g is turned on,
The drive roller 3b+ is driven and rotated to convey the recording sheet 1 to the recording position.

The driving force is transmitted to the pair of discharge rollers by connecting the registration motor 3f directly to the drive roller 3c+.
The drive roller 3c is configured to be driven and rotated by the drive of the drive roller 3c.

Therefore, each motor 3d, 3f and clutch 3e, 3g
By driving and controlling the recording sheet 1, the recording sheet 1 is transferred to the feeding roller pair 3''l+3az, the registration roller pair 3b, .
3bz and a pair of discharge rollers 3cl and 3cz.

As shown in FIG. 1, a registration sensor 3h is provided immediately before the pair of registration rollers 3b+, 3bz in the sheet conveyance direction, and a pair of discharge rollers 3c.

A discharge sensor 31 is provided immediately after 3Cz.

The sensors 3h and 3i are composed of reflective sensors, etc., and are turned on when the recording sheet 1 is detected, and turned off when not detected, and are sensors that detect whether or not the leading edge of the recording sheet 1 has passed the sensor position. It is something to detect.

(Sheet suction means) The sheet suction means 4 is for suctioning the recording sheet 1 conveyed by the conveyance means 3, and maintains a constant distance between the recording means 5 and the recording sheet 1.

This suction means 4 has a box-shaped suction platen 4a located at a position facing the recording means 5 across the conveyance path of the recording sheet 1.
is provided, and a large number of suction holes 4b are bored in the sheet facing surface of the platen 4a. The platen 4a communicates with a suction pump 4d via a suction pipe 4c.

Therefore, when the pump motor (not shown) is driven and the suction pump 4d is activated, negative pressure is generated within the platen 4a.
This negative pressure causes the recording sheet 1 to be sucked through the suction hole 4b.

The suction force of the recording sheet 1 is such that the sheet 1 is not lifted off the platen 4a, and the pressure is such that the sheet conveyance is not overloaded.

(Recording means) The recording means 5 records an ink image on the recording sheet conveyed by the conveying means, and in this embodiment, it is disposed between the registration roller pair 3b, 3bt and the ejection roller pair 3c1, 3C2. There is. As the recording means in this apparatus, an inkjet recording method is suitably used.

The inkjet recording method includes a liquid ejection port for ejecting recording ink liquid as flying droplets, a liquid flow path communicating with the ejection port, and a part of this liquid flow path. and ejection energy generating means for providing ejection energy for causing the ink liquid to fly. The ejection energy generating means is then driven in accordance with the image signal to eject ink droplets and record an image.

As the ejection energy generation means, for example, a method using a pressure energy generation means such as an electromechanical transducer such as a piezo element, or a method in which an am wave such as a laser is irradiated and absorbed by the ink liquid to generate heat, and the ink is heated by the action of the heat generation. There is a method using a 1:1 magnetic energy generating means for ejecting the ink, or a method using a thermal energy generating means for ejecting the ink by heating the ink liquid with an electrothermal converter. Among these methods, the method of ejecting ink using a thermal energy generating means such as an electrothermal converter is capable of high-resolution printing because liquid ejection ports can be arranged in a high density, and the print head is compact. It is suitable because it can also be

In this embodiment, a serial bubble jet recording method, which is one of the inkjet recording methods described above, is used as a recording means.

Its structure is such that a guide rail 5a is attached parallel to the platen 4a across the sheet conveyance path, and a carriage 5b is slidably attached to be guided by the guide rail 5a. A timing belt 5f stretched between a driving pulley 5d and a driven pulley 5e connected to a carriage motor 5C is connected to the carriage 5b.

Therefore, the carriage 5b reciprocates in the width direction of the recording sheet 1 by rotating the carriage motor 5C in forward and reverse directions.

Further, a recording head 5g is mounted on the carriage 5b. This recording head 5g is a bubble jet head, and its structure is as shown in FIG.

In the exploded explanatory diagram of Fig. 3, 5g+ is a heater board, and an electrothermal converter (discharge heater) 5 is mounted on a silicon substrate.
g2, 5g of electrodes such as aluminum to supply power to this
x is formed and arranged.

For this heater board 5g+, the recording liquid liquid path (
Nozzle) Top plate 5gs with a partition wall to partition 5g4
It is constructed by gluing. Further, an ink cartridge for supplying ink to the recording head 5g is replaceably attached to a predetermined position of the apparatus.

The ink supplied from the ink cartridge through the conduit is filled into a common liquid chamber 5g+ in the recording head 5g through a supply port 5g6 provided on the top plate 5gs, and is introduced into each nozzle 5ga from this common liquid chamber 5g7. It will be destroyed. Ink ejection ports 5ge are formed in these nozzles 5gn,
Further, the ejection ports 5ge are formed at a predetermined pitch in the sea 1-Jll feeding direction, facing the recording sheet of the recording head 5g.

In this embodiment, recording is performed by ejecting and flying ink from the recording head 5g in synchronization with the movement of the carriage 5b.

Regarding the principle of ink flight in the bubble jet recording method, a typical principle is, for example, US Pat. No. 47
It is disclosed in the specification No. 23129 and the specification No. 4740796.

To briefly explain this with reference to FIGS. 4(a) to (g), in a steady state, as shown in FIG. 4(a), the nozzle 5
The surface tension and external pressure of the ink 8 filled in g< are balanced on the ejection port surface. When the ink 8 is to be ejected in this state, the electrothermal converter 5gz in the nozzle 5g4 is energized to cause the ink in the nozzle 5g4 to undergo a rapid temperature rise exceeding nucleate boiling.

Then, as shown in FIG. 4 0:l), the electrothermal converter 5
The ink adjacent to 8t is heated and forms microbubbles.
The ink in the heated area is vaporized and film boiling occurs.
As shown in FIG. 4(C), the bubbles 9 grow rapidly.

When the bubble 9 grows to the maximum as shown in FIG. 4(d), an ink droplet is pushed out from the ejection opening in the nozzle 5ga. Then, when the electricity to the electrothermal converter 5gz is finished,
As shown in FIG. 4(e), the grown bubble 9 is transferred to the nozzle S.
The bubbles are cooled and contracted by the ink 8 in the ga, and as a result of the growth and contraction of the bubbles, ink droplets fly from the ejection ports.

Furthermore, as shown in FIG. 4(f), the ink comes into contact with the electrothermal transducer 5gz surface and is rapidly cooled, and the bubbles 9 disappear or shrink to an almost negligible volume. When the bubble 9 contracts, the nozzle 5 as shown in FIG.
Ink is supplied into g4 from the common liquid chamber 51h by capillary action in preparation for the next energization.

Therefore, while reciprocating the carriage 5b, the electrothermal transducer 5g is synchronized with this movement in accordance with the image signal.
An ink image is recorded on the recording sheet by energizing z.

Incidentally, in the inkjet recording method, it is preferable to provide a recovery means at the end of the movement range of the carriage.

The recovery means has the function of covering the ink ejection surface of the print head 5g during non-printing, thereby preventing the ink near the ejection ports of the print head 5g from drying up and solidifying accordingly. In addition, a pump is connected to the second recovery means, and the pump is driven to prevent ink discharge failure, removal, or the like, and the recovery process is performed by suctioning ink from the discharge port using its suction force.

(Cutter) The cutter 6 cuts the recording sheet 1 from the trailing edge of the image, and in this embodiment, the cutter 6 cuts the recording sheet 1 from the trailing edge of the image.
3az and a pair of registration rollers 3bl and 3b2.

As shown in FIG. 5, the configuration is such that a slit 6a having a length greater than the width of the recording sheet 1 is formed in the canter unit, and a round blade 6b is movably attached along the slit 6a. Specifically, a guide rail 6C is attached parallel to the slit 6a, and this rail 6C
A carriage 6d to which a round blade 6b is attached is movably attached along. A heald 6f stretched between a drive pulley 6e and a driven pulley 6f attached to both ends of the guide rail 6C is connected to the carriage 6d, and the round blade is driven by a cutter motor 6h connected to the drive pulley 6d. 6b moves along the slintro a.

Therefore, when the cutter 6 is installed so that the slit 6a is located on the conveyance path of the recording sheet 1, and the canter motor 6h is driven with the recording sheet 1 inserted through the slit 6a, the recording sheet 1 is cut by the round blade 6b. It is something that will be done.

(Sheet holding means) The sheet holding means holds the recording sheet 1 when the cutter 6 cuts the sheet. In this embodiment, the free rotation of the feeding roller pair 3a and 3a2 is restricted when cutting the sheet, so that the recording sheet 1 is transferred to the feeding roller pair 3a.
I try to keep it at 1, 3 az.

That is, the drive roller 3a+ is in a free rotation state when the feed latch 3e is off, but when the clutch 3e is turned on, the drive roller 3a+ and the feed motor 3d are rotated.
are connected, and the rotational load increases compared to the free rotation state. Therefore, when the clutch 3e is turned on with the recording sheet 1 being held between the pair of feeding rollers 3a+ and 3az, even if a downward reaction occurs in FIG. 1 against the recording sheet 1 when the sheet is cut, the feeding roller vs. 3a+, 3az
The recording sheet 1 is held securely, and there is no possibility that the sheet 1 will fall off from the feeding roller pair 3 a + + 3 a z.

(Control Means) Next, a control system for controlling the drive of each of the above-mentioned members will be explained.

In FIG. 6, numeral 10 represents a control unit, including CPU10a,
It consists of a ROM 10b, a RAM 10c, etc.

The CPU 10a is a central processing unit, and the ROM (described later)

The control unit 10 receives an image signal from an external device 11 and an instruction signal from an operation panel 13 via an interface 12.
Alternatively, input signals from the registration sensor 3h and discharge sensor 3i, and operate the feed motor 3d, registration motor 4c, carriage motor 5c, and cutter motor 6h.
Or a pump motor 14 that operates the suction pump 5d.
Respective motor drivers for driving 15.16
．． 17. Outputs a drive signal on 18.19, also outputs an on/off signal to the feed latch 3e and registration clutch 3g, and further outputs a drive signal to the head driver 20 for driving the recording head 5g. It's very powerful.

Next, the sheet conveyance and recording cutting procedures based on signals from the control section 10 will be explained with reference to the flowchart of FIG.

When a recording start signal is input in step S1, step 32. Proceeding to S3, the feed motor 3d is turned on, and the feed latch 3e is also turned on, and the feed roller pair 3 al+ is turned on.
382, the recording sheet 1 is conveyed upward in FIG. Then, the process moves to steps S4 to S7, and after the registration sensor 3h detects the leading edge of the sheet, the feeding motor 3d and the feeding latch 3e are turned off after a predetermined period of time has elapsed.

During the predetermined time, the leading edge of the sheet is in the position of the registration roller pair 3b+;
3. The time is long enough for the recording sheet 1 to contact the nip portion of the recording sheet 1 and form a loop.
skewness is corrected.

Next, the process moves to step 58 to Sll, where the registration motor 3r and the registration clutch 3g are turned on to transfer the recording sheet to the registration roller pairs 3b+, 3bz and the ejection roller pair 3.
c+, 3cz, and after the discharge sensor 31 detects the leading edge of the sheet, the sheet is transported by a predetermined amount, and the registration motor 3f and the registration club 3g are turned off. This allows the recording sheet 1 to be located.

Next, the process moves to step S14, and 1 is written for each recording sheet 1.
Perform line recording. This recording operation is performed by the pump motor 14.
is driven to attract the recording sheet 1 to the platen 5a, and in this state, the carriage motor 5C is driven to move the carriage 5.
While moving b, the recording head 5g is moved in synchronization with this.
This is an operation for recording an ink image on the recording sheet 1 by driving the ink according to an image signal.

When one line recording is completed as described above, step S15
The process moves to step S16 to determine whether or not the recording has ended, and if the next line is recorded, the process moves to step S16 and the registration motor 3f is activated.
is driven, and the recording sheet 1 is conveyed one line by the discharge roller pair 3c+3cz. Note that the sheet 1 is conveyed with some tension applied thereto.

Next, in step S17, it is determined whether or not to cut the recording sheet 1. If the recording sheet 1 is not to be cut, the process returns to step 7 314 to record the next line, and if it is to be cut, step 31
Move to 8.

Steps 318 to S20 are sheet cutting operations, in which the recording sheet l is transferred to the feeding roller pair 3aI+38z
Hold it so that it does not fall off. That is, step S18
After turning on the feeding latch 3e, step S1
At step 9, the canter motor 6g is driven to cutter 6.
is driven to cut the recording sheet 1. When the feed latch 3e is turned on, the feed roller pair 3a+,
Even if a downward reaction as shown in FIG. 1 occurs in the sheet 1 when cutting the sheet due to the increased rotational load of the sheet 3az, the sheet 1 is reliably held by the pair of feeding rollers 3a+ and 3az and will not fall off. Never.

After cutting the sheet as described above, the feed roller pair 3
Even if the sheet holding force at al+ 38z is weak, the recording sheet l will not fall off from the feeding roller pair 3a+, 3az, so the process moves to step S20 and the feeding latch 3e
is turned off, and the process returns to step S14 to execute recording of the next line and subsequent lines.

When the recording is completed, the process moves from step S15 to step S21, and the registration motor 3f is driven by a predetermined amount to discharge the recording sheet 1 on which the image has been recorded from the discharge lower.

As mentioned above, when cutting the sheet, the feeding roller pair 3a1゜3a,
By increasing the sheet holding force of the recording sheet 1, the recording sheet 1 is prevented from falling off during sheet cutting.

[Other Embodiments] Next, other embodiments of each part of the recording apparatus described above will be described.

(Sheet holding means) In the embodiment described above, when cutting the sheet, the feeding latch 3e is turned on and the recording sheet 1 is transferred to the feeding roller pair 3a 1+3.
However, a feed motor 3d that can be locked electrically or mechanically is used, and the feed motor 3d is locked to hold the recording sheet 1 as shown in the flowchart of Fig. 8. You may also do this.

In the flowchart of FIG. 8, steps 31 to S17
Since the steps up to this point are the same as those of the embodiment described above, the explanation will be omitted. In this embodiment, when cutting the sheet, the feed motor 3d is increased by 0.7 in step S18, and step S19
At this point, the feed lunch 3e is turned on. As a result, the feeding roller pair 3a+, 3az no longer rotates. Therefore, when recording sheet 1 is cut in step S20, sheet 1
Even if a reaction occurs on the
It will not fall off from az.

After cutting the sheet as described above, step 321;
At 322, the feed latch 3e is turned off, the feed motor 3d is unlocked, and the process returns to step S14.

By locking the feed motor 3d and cutting the sheet in this way, it is possible to more reliably prevent the sheet from falling off.

Further, as another example of the sheet holding means, FIG. 9(a),
As shown in (b), the recording sheet l may be held by a sheet pressing member 21.

In this embodiment, feeding roller pair 3 al+3
A sheet pressing member 21 and a sheet pressing plate 22 sandwich the sheet Ill feeding path between aZ and the cutter 6.
and a solenoid 2 is provided on the sheet pressing member 21.
Connect 3. When the solenoid 23 is turned on, the sheet pressing member 21 presses the pressing plate 22 as shown in FIG. 9(b), and when the solenoid 23 is turned off, the pressing member 21 is separated from the recording sheet 1 as shown in FIG. 9(a). It is composed of

Therefore, when cutting the recording sheet 1, the solenoid 23 is turned on and the recording sheet 1 is held by the sheet pressing member 21 and the pressing plate 22, and even if the solenoid 23 is turned off after cutting the sheet, it is not possible to use the above-described embodiment. A similar effect can be obtained.

Further, as another embodiment of the sheet holding means, it may be constructed as shown in FIG. This is because a sheet sensor 24 is installed just before the cutter 6 in the sheet conveyance direction, and when the recording sheet 1 falls downward due to the reaction of cutting the sheet,
This is detected by the sensor 24 and the feeding motor 3d is driven. In this embodiment, the sheet sensor 24 is turned on when it detects the recording sheet 1, and turned off when it is not detected.

Specifically, control is performed as shown in the flowchart of FIG. In the flowchart of FIG. 1I, steps S1 to
The steps up to S17 are the same as those in the embodiment described above, so the explanation will be omitted. In this embodiment, when the recording sheet 1 is cut in step 318 and the sheet 1 falls due to the reaction, the sheet sensor 24 is turned off. Therefore, if the sheet sensor 24 is turned off in step S19, the feeding motor 3d and the feeding latch 3e are turned on in steps S20 and S21, and the feeding roller pair 3a is turned on.
+, 3az to convey the falling sheet 1 upward.

Then, the process moves to steps 322 to S24, where the leading edge of the sheet is fed to the position of the sheet sensor 24, and when the sensor 24 is turned on, the motor 3d and clutch 3e are turned off.

The sheet 1 falls, and its tip reaches the feeding roller pair 3a+
, 3az, the sheet 1
Since the sensor 24 detects the falling of the recording sheet 1 and drives the feeding motor 3d at a sufficiently fast speed, the recording sheet 1 does not fall from the nip portion and the feeding roller pair 3al, 3 is moved.
It will be held at az.

(Sheet Conveying Means) In the above-mentioned embodiment, an example was shown in which the sheet conveying means 3 was composed of a pair of rollers, and the recording sheet 1 was conveyed by rotating this pair of rollers. It is not necessary to limit the recording sheet 1 to a roller-like one, for example, and the recording sheet 1 may be conveyed by a rotating heald or the like.

(Recording Means) In addition to the configuration of the above-mentioned combination of ejection ports, liquid paths, and electrothermal converters (linear liquid flow path or right-angled liquid flow path), the recording head 5g in the recording means has a U.S. Patent No. 4,558,333, in which the action part is arranged in a bent area
The structure disclosed in the specification of No. 459600 may be adopted. Furthermore, Japanese Patent Application Laid-Open No. 123670 of 1981 discloses a configuration in which a slit common to a plurality of electrothermal converters is used as a discharge part of the electrothermal converter, and a hole that absorbs pressure waves of thermal energy is used as a discharge part. A configuration based on Japanese Patent Application Laid-Open No. 138461 of 1983, which discloses a configuration corresponding to the above, may also be suitably adopted.

In addition, the above-mentioned recording means is an example of a recording gutter 5g that is attached to the carriage in advance, but this is attached to the carriage etc. to connect electrically with the main body of the apparatus and to supply ink from the main body of the apparatus. It is also possible to use a replaceable chip-type recording head that allows the recording head to be freely replaced, or a cartridge-type recording head provided in the recording head itself.

Furthermore, although the serial bubble jet recording method was illustrated in the above embodiment, it is also possible to perform so-called full line recording using a full line type recording head having a length corresponding to the width of the maximum recording sheet that can be recorded by the recording apparatus. You can also do it. As the full line type recording head,
A plurality of the recording heads described above may be combined to satisfy the length, or one integrally formed recording head may be used.

Furthermore, the recording mode of the recording device is not limited to a recording mode in which only the mainstream color such as black is used, but it is also possible to configure the recording head integrally or by combining a plurality of recording heads, but it is also possible to use a recording mode in which the recording head is configured integrally or by a combination of multiple colors. It may be provided with at least one full color.

Furthermore, in the above-mentioned embodiments, the ink was explained as a liquid, but it is an ink that solidifies at room temperature or lower, and is softened or liquid at room temperature, or in the above-mentioned inkjet, the ink itself is in a temperature range of 30°C or more and 70°C or less. Generally, the temperature is adjusted so that the viscosity of the ink is within a stable ejection range, so it is sufficient if the ink is in a liquid state when the drive signal is applied. In addition, should the temperature rise caused by thermal energy be actively prevented by using it as energy for changing the layer of the ink from a solid state to a liquid state, or should an ink that solidifies when left standing be used to prevent evaporation of the ink? In any case, the thermal energy may be applied in response to a recording signal to liquefy the ink and be ejected as liquid ink, or the ink may already begin to solidify by the time it reaches the recording sheet. It is also possible to use an ink that liquefies only when In the state of this embodiment as a solid object, it may be in a form that faces the electrothermal converter.

Incidentally, the most effective method of the present invention for each of the above-mentioned inks is one in which the above-mentioned film boiling method is executed.

Furthermore, the recording means of the present invention need not be limited to the bubble jet recording method described above. For example, a so-called thermal transfer recording method, in which an ink sheet coated with heat-melting ink is heated in accordance with an image signal and the melted ink is transferred to the recording sheet;
Various recording methods can be employed, such as a so-called thermal recording method in which a recording sheet that develops color with heat is heated in accordance with an image signal, and a so-called wire tod recording method in which recording is performed by striking an ink ribbon with a wire in accordance with an image signal. .

Therefore, the recording head is not limited to the above-mentioned bubble jet head; for example, a thermal head, a wire dot head, a daisy-wheel head, etc. can be used.

In addition to being used as a printer, which is an image output terminal for information processing equipment such as a computer, the above-mentioned recording device can also be used as a copying device combined with a reader, etc., and also as a facsimile device having a sending and receiving function. It will be done.

<Effects of the Invention> As described above, the present invention securely holds the recording sheet when cutting it, so even if a slippery sheet or a heavy sheet is used as the recording sheet,
This can prevent the sheet from falling off the conveyance means.
