Description

  The present invention relates to a printer, and more particularly to a printer capable of continuing sheet-fed paper issuance even when a cutting unit for separating a printed paper part from continuous paper does not operate due to a failure or the like.

  The mountless label printer uses a label roll in which the mountless label paper is wound in a roll shape, and pulls out the mountless label paper by the operation of the platen roller (paper feeding part) that constitutes the printing unit. A predetermined item is printed by a print head (thermal head) sandwiching the mountless label paper on the sheet, and after the printing is finished, the mountless label paper is moved toward the label issuing port by the operation of the platen roller, and slightly from the print unit. A position slightly upstream from the printed label portion is cut by a cutting portion arranged on the downstream side, and the label is sent out of the apparatus through a label issuing port. Then, the leading edge of the mountless label sheet from which the print label has been separated by the cutting unit is back-fed to a position near the downstream of the printing unit in preparation for the next label printing issue (see, for example, Patent Document 1).

However, even if the cutting unit becomes inoperable due to a failure of the motor that moves the blade body, damage to the electrical system, or the like, the printing unit operates, so that the predetermined printing is not performed on the mountless label paper. Although it is possible, since the cutting section is inoperable, the printed label that has been printed cannot be separated from the mountless label sheet. Accordingly, when the cutting unit becomes inoperable, a problem arises in that the printer cannot be used (label issuance) until the failure is resolved by having a service engineer look at the cause of the failure.
If the cutting unit is inoperable, it may be possible to print a predetermined item on the mountless label paper by operating the printing unit normally. In this case, the printed label portion is sent out of the apparatus. In order to do this, the platen roller that feeds out the mountless label paper must be actuated (rotated) differently from the normal label issuance, and before and after the print label to cut it manually outside the device. As a result, a large number of blank portions are provided, a poor-looking label is issued, and the amount of waste of label paper increases.

JP 2010-5943 A

  The present invention has been made in view of the above-described problems of the prior art, and even when a cutting unit that cuts off a printed paper portion becomes inoperable or has poor sharpness, a sheet-like paper that is normally issued (for example, Another object of the present invention is to provide a printer capable of continuously issuing sheet-like paper (for example, a label or a receipt) that is not different from a label or a receipt.

In order to solve the above-mentioned problems, the printer of the present invention prints a predetermined item on the continuous paper drawn from the roll paper by the operation of the paper feeding means at the printing unit, and the printed paper part is separated from the continuous paper by the cutting means. a printer for output feeding the paper sheet form, said cutting means, detachably to the first cutting portion attached, disposed on the upstream side feed paper than the first cutting unit to the printer main body portion A second cutting unit that is exposed when the first cutting unit is detached from the printer main body unit, and a receiving unit that receives a print instruction from the printing unit, the first cutting unit, or the first cutting unit. two display means for displaying the options to use one of the cutting portion, wherein the when the use of the first cutting portion is selected by the display means, substantially print position the continuous paper In a first backward feed control to wait, when the use of the second cutting unit is selected by the display unit, the second back to wait at substantially the printing position of the continuous paper and accepts print instruction by the receiving unit further comprising wherein the Rukoto control unit which performs feed control, the.

The sheet feeding means is generally a platen roller that constitutes a printing unit, but is not limited thereto, and a dedicated roller member that feeds the sheet may be provided separately from the platen roller.
The first cutting part may be of any cutting method, structure, such as a shearing type cutting blade composed of a fixed blade and a movable blade, or a rotary cutting blade. In addition, the first cutting unit is a unit, and is a detachable type that is detachably attached in the case downstream of the printing unit or outside the case, or a fixed type that is integrally assembled in a case having an issue port. Any of them may be used.
Cutting margin following the printed portion to be sent to the issuing extraoral is not particularly limited length of (non-printing portion for disconnecting), for example, in a typical first issue mode, blank space between the sheet issuing direction printing paper one another The dimensions are mentioned.
Examples of the continuous paper include a mountless label paper in which an adhesive layer is formed on the surface opposite to the printing surface, or a roll paper for receipt in which the adhesive layer is not formed on the surface opposite to the printing surface.

  According to the above means, in addition to the first issuing mode (automatic label issuing mode) in which the printing paper is automatically cut and issued from the continuous paper by the operation of the cutting unit, the printing paper portion is connected to the continuous paper while being connected to the continuous paper. Because it has a second issue mode (manual label issue mode) that sends the cutting allowance (non-printing part for separation) following the to the outside of the issuing port, for example, the cutting part failed and became inoperable In this case, even when the cutting unit operates but the sharpness is deteriorated, the printing can be continuously issued by setting the second issue mode. The length of the cutting allowance (the non-printing portion for separation) following the paper portion that is sent out to cut the printing paper portion from the continuous paper out of the issuing port is controlled to a constant length. Without wasting, it is possible to issue a good-looking paper that is almost the same as the paper issued in the first issue mode. The continuous paper feeding length by the operation of the paper feeding unit in the second issue mode is longer than the continuous paper feeding length by the operation of the paper feeding unit in the first issue mode.

As a method for setting the paper issue mode to the second issue mode, for example, an operation unit for setting the second issue mode is provided, and manual switching is performed by switching the operation unit by an operator. Specifically, when the operator determines that a failure (inoperable) is observed by looking at the operation of the cutting unit, or when the non-operation (inoperable) of the cutting unit is detected by a detection unit (sensor or the like), For example, when non-operation is detected, the operation unit is operated in accordance with the notification (or display).
As the detection unit, for example, a sensor is provided in the movable range (protrusion range) of the movable blade constituting the cutting unit, and whether or not the movable blade is detected by the sensor within a predetermined time during which the movable blade operates. If it is determined and not detected, it is determined that the cutting section is inoperative (inoperable), and is notified or displayed.
Examples of the operation unit include a push button for switching to the manual label issue mode, a “manual label issue mode” selection switch displayed on the display unit (touch panel), and the like.

According to the above means, the control unit sends a signal from the operation unit via the operator's operation based on the operator's own visual judgment or the detection information by the detection unit (sensor) that the cutting unit is inoperable. When receiving, the control unit switches the operation of the sheet feeding unit from the first issue mode to the second issue mode.
That is, during normal operation (first issue mode) in which the cutting unit operates normally, the sheet feeding unit removes a continuous sheet on which predetermined items have been printed slightly from the rear end of the printed sheet (printed area) in the upstream direction. The control unit is operated so that the position where the cutting allowance of the dimension is moved is positioned on the line of the cutting unit. The cutting portion (the non-printing portion for separation) following the paper portion is operated to be sent out of the issuing port while the paper portion on which the predetermined matter is printed is connected to the continuous paper. As a result, the cutting allowance (the non-printing portion for separation) following the printing paper sent out of the issuing port can be separated from the continuous paper by the scissors or the cutter. The length of the cutting allowance (the non-printing portion for separation) is controlled by the control portion so that the operation of the paper feeding portion is controlled, so that it is possible to prevent the margin portions existing before and after the printing area from becoming unnecessarily long. It is possible to issue a paper that is almost the same as the paper that is normally issued.

In addition, when the control unit receives a signal by pushing the operation unit, the printing unit prints a predetermined matter on the continuous paper, and then the predetermined distance in the upstream direction from the rear end of the printed region along the paper issuing direction. It is also possible to control so as to print a cut mark on the cutting margin portion, and to control the operation of the sheet feeding portion so that the cut mark is sent out of the issuing port.
When the issuance port is formed in a cutter unit that is detachably attached to the main body case, the issuance port when the cutter unit is removed due to failure or the like and the paper is cut and issued in the second issuance mode, The position of the issuing port when the cutter unit is attached, or the vicinity of the downstream side of the contact position between the print head and the platen roller of the printing unit exposed by the removal of the cutter unit is the issuing port.

Also, the paper on which the predetermined printing has been performed is sent out of the issuing port by the operation of the paper feeding section, and the printing paper portion is cut into a sheet by manual operation with a hook or a cutter. In order to be able to do easily without using a cutter or a cutter, a manual separation unit for separating the printing paper from the continuous paper may be provided at the issuing port.
Examples of the manual separation unit include a cutting blade (a jagged blade) provided in a tape cutter or the like. The cutting blade may be fixed so as to face the issuing port, or may be movable so as to face the issuing port at the time of cutting.

  In the printer according to the present invention, even when the cutting unit cannot be separated due to a failure or the like, the sheet feeding unit that feeds the continuous sheet has a cutting margin portion that follows the portion on which the continuous sheet is printed. Since it is controlled so that it is sent out of the issue port, paper (for example, labels and receipts) can be continuously issued without wastefully providing a blank portion in the front-rear direction of the print area and without deteriorating the appearance. it can.

It is a schematic diagram which shows an example of the implementation which provided the manual separation part in the issue port, (a) is a front view, (b) is a side view. The flowchart figure which shows the flow of the label issuing in the case of performing automatically the non-operation (inoperability) of a cutting part by a detection part (sensor). The flowchart figure in the case of performing non-operation of a cutting part by input operation of the operation part by an operator. (A) is a schematic diagram showing the delivery of the mountless label paper when the cutting unit operates normally, and (b) is a schematic diagram of a state in which the mountless label paper is back-fed after the operation of the cutting unit.

Hereinafter, an example of an embodiment of a printer according to the present invention will be described with reference to the drawings for a mountless label printer.
FIG. 1 schematically shows the configuration of a mountless label printer A. Reference numeral 1 denotes a label roll (roll paper) in which a long strip of mountless label paper (continuous paper) 1a is wound in a roll shape. A printing unit 3 including a print head 3a and a platen roller 3b (paper feeding unit) is disposed on the downstream side in the pulling direction of the mountless label paper 1a. A cutter 4 (cutting portion) is arranged near the downstream side, and a label receiver 5 is sequentially arranged near the outside (downstream side) of the label issuing port (issuing port) 10 opened in the case 9 downstream of the cutter 4. Yes.
In addition, a sensor 6 (detection unit) that detects whether or not the cutter 4 is operating normally is disposed within the operating range of the cutter 4. Further, a mount-less label sheet 1a fed on the label receiver 5 (or a cut sheet-like sheet) is disposed at a position almost directly above the rear end side of the label receiver 5 (opposite to the label paper feeding direction). A label detector 7 for detecting the presence or absence of the mountless label 20) is disposed.

  In the label roll 1, a long strip-like mountless label paper 1a having a printing surface on one side (upper surface) and an adhesive surface coated with an adhesive on the other side (lower surface) is subjected to a peeling process on the printing surface. It is wound in a roll shape and is rotatably supported by the roll loading unit 2. Then, the mountless label paper 1a pulled out from the label roll 1 is supplied between the print head 3a and the platen roller 3b of the print unit 3 via the guide roller 8, and the mountless paper is removed by the driving rotation of the platen roller 3b. The label paper 1a is pulled out.

  The print head 3a of the printing unit 3 is constituted by a thermal head, and printing is performed on the printing surface of the mountless label paper 1a which is transferred by selectively generating heat from the heating element of the print head 3a. Further, the platen roller 3b for attaching the mountless label paper 1a with the print head 3a is coated with a release agent on the surface, and is applied to the adhesive surface opposite to the print surface of the mountless label paper 1a. The adhesive that has been applied is prevented from adhering, so that the mountless label paper 1a is smoothly fed out. The configuration in which the adhesive applied to the adhesive surface of the mountless label paper 1a is less likely to adhere to the platen roller 3b is not limited to the above configuration, and the platen roller 3b itself or the outermost layer portion of the platen roller 3b is easily peeled off. You may comprise by the member of property. The platen roller 3b is driven and rotated by a drive motor (stepping motor) 15.

The cutter 4 for cutting the mountless label paper 1a on which the data for one label is printed by the printing unit 3 is composed of a pair of upper and lower belt blades for cutting the mountless label paper 1a by a shearing action. . Specifically, the fixed blade 4a disposed on the lower side of the mountless label paper 1a that is sent out linearly, and the movable that is disposed on the upper side of the mountless label paper 1a and moves forward and backward toward the fixed blade 4a. The movable blade 4b is configured to be driven by a motor (stepping motor) 16.
The cutter 4 is disposed on the downstream side of the printing unit 3 and close to the platen roller 3b. The cutter 4 (cutting unit) may be unitized and detachably disposed at a position near the downstream of the printing unit 3. In this case, the label issuing port (issuing port) 10 is formed in the case of the cutter unit. When the cutter unit is removed due to malfunction or the like, the print head 3a and the platen roller 3b of the exposed printing unit 3 are exposed. The downstream side part from the contact position with is the issuing port.

The mountless label paper 1a on which data for one label is printed is sent to the downstream side between the fixed blade 4a and the movable blade 4b of the cutter 4, and the supplied paperless label paper is sent out. A label receiver 5 that supports the portion 1a in a substantially horizontal shape is disposed in the vicinity of the downstream side of the label issuing port 10 of the case 9.
The label receiver 5 supports and supports the rotating cylinder 5a whose outer peripheral surface is easily peeled off and both widthwise sides of the mountless label sheet 1a that is sent downstream from the rotating cylinder 5a (left side in the drawing). The surface of the support plate 5b that is in contact with the adhesive surface of the mountless label paper 1a is formed of an easily peelable treatment or an easily peelable member. As a result, the mountless label paper 1a to be printed out is supported substantially horizontally by the label receiver 5, and the cutting operation by the cutter 4 is stably performed. Further, the mountless label 20 cut into a sheet of a predetermined length by the cutter 4 is adsorbed by an adsorbing means (applicator) in the case of automatic application by a machine until it is removed by an operator in the case of manual application. Until it is held in a substantially horizontal state. The form of the label receiver 5 is not limited to the example shown in the figure, and the board-less label paper 1a to be sent or the sheet-like board-less label 20 to be cut and issued is held substantially horizontally until the next operation is performed. Any configuration that does not hinder removal of the mountless label can be used.

The sensor (detection unit) 6 detects whether or not the cutter 4 is operating normally. Specifically, the sensor 6 is disposed in a movable range of the movable blade 4b constituting the cutter 4. Then, it is determined whether or not the movable blade 4b is detected by the sensor 6 within a predetermined time during which the movable blade 4b operates. If not, the cutter 4 (cutting portion) is determined to be inactive (inoperable). A signal is output to a control unit (CPU) described later.
In addition to the automatic detection by the sensor (detection unit) 6, the inoperability of the cutter 4 is instructed by the operator visually judging (detecting) the cutting state of the mountless label paper 1 a or the operation of the cutter 4. It is also possible to set. Specifically, when an operator visually determines (detects) an abnormality (failure or the like) of the cutter 4, a means for inputting the fact to the control unit (CPU) may be provided. As the input means, a dedicated push button (second issue mode selection button) operated when the cutter 4 is abnormal (failure) or “second issue mode” is selected from the display / operation unit 14 described later. The method of operation etc. are mentioned.

The label detection unit 7 is composed of a reflection type optical sensor, and the mountless label sheet 1a on the label receiver 5 or the cut and issued sheetless mountless label 20 on the label receiver 5 due to a change (difference) in the level of reflected light to be received. Presence or absence is detected.
The detection timing of the label detection unit 7 is controlled so as to be performed after the rotation of the platen roller 3b for sending the mountless label paper 1a from the position of the print head 3a toward the label receiver 5.

  FIG. 2 is a block diagram showing an electrical configuration of a control unit (microcomputer) that controls the operation of the mountless label printer A shown in FIG. 1, and includes a CPU 11, a flash memory 12, a RAM 13, a display / operation unit. 14, an interface circuit 15, a driving motor (stepping motor) 16 that rotates the platen roller 3 b, a thermal head (printing head) 3 a, a cutter driving motor 17, a sensor (detection unit) 6, and a label detection unit 7.

The CPU 11 is a central processing unit that executes a program stored in the flash memory 12 and supervises the operation of the mount-less label printer A.
The flash memory 12 is a read-only memory that stores a control program for the mountless label printer A, control data, and the like.
The RAM 13 has a work area for temporarily calling and processing data. Among them, a dot development area for developing print data into dot data, and a call for calling and storing one format data from a label format file. There are a format area, a call product area for calling and storing product data and the like. Further, the RAM 13 stores a label format file in which a label printing format is set, a product file in which various product data for label printing are set, and the file is held even when the power is turned off. The battery is backed up.

The display / operation unit 14 is an input device for operating the mount-less label printer A. The display / operation unit 14 is a touch panel integrated with the display unit, and is a liquid crystal display that displays various menu screens and data. is there.
A driving motor (stepping motor) 16 that drives and rotates the platen roller 3b, a thermal head (printing head) 3a, and a cutter driving motor 17 constitute a printing unit of a label issuing unit, and mountless label paper based on a command from the CPU 11 A product name, a price, a unit price, a barcode, and the like are printed on 1a, and the mountless label paper 1a printed is cut into sheets by a cutter 4 and a mountless label 20 is issued.
The sensor (detection unit) 6 monitors the operation of the movable blade 4b in the cutter 4, and if the operation of the movable blade 4b within the predetermined time (protrusion movement toward the fixed blade) is not confirmed, the cutter 4 is not activated. It is determined that the operation is impossible, and a signal indicating that the cutter 4 is inactive is transmitted to the CPU 11. The non-operation (inoperable) of the cutter 4 is set not only by an output signal from the sensor (abnormality detection unit) 6 but also by a signal output by a push button by an operator or an operation of the display / operation unit 14. Is possible.
The label detection unit (sensor) 7 detects the presence or absence of the mountless label sheet 1a or the mountless label 20 on the label receiver 5, and the operation (drive / stop) of the printing unit 3 is controlled based on the detection result. The

  FIG. 3 shows an example in which the label issuing port 10 is provided with a manual separation unit 19 for separating the print label portion connected to the mountless label paper 1a sent out of the label issuing port 10 from the mountless label paper 1a. A cutting blade 19 (manual cutting portion) having a jagged blade portion formed at the upper opening edge of the mouth 10 is fixed. As a result, the mounted paper-less label paper 1a sent out of the label issuing port 10 is pulled up in the direction of the upper edge of the label issuing port 10 and pressed against the cutting blade 19, thereby separating the printed paper-less label paper. it can.

Next, the flow of cutting and sending the printed label will be described based on the flowchart of FIG. The print label cutting and sending flow shown below is a flow that starts when a necessary operation is performed from the display / operation unit and an instruction to issue a label is issued, and the sensor (detection unit) 6 cuts the cutter. 4 shows the case of automatic detection in which the operation 4 is monitored.
(ST1) ... It is determined whether there is an instruction to issue a label from the display / operation unit 14, and if there is an instruction (YES), the process proceeds to ST2, and if there is no instruction (NO), the above determination is repeated.
(ST2) ... It is determined whether or not there is an abnormality (failure) in the operation of the cutter 4, and if an abnormal non-operation is detected (YES), the process proceeds to ST3, and if there is no abnormality and normal (NO), ST10 Proceed to

(ST4) ... The print data of the corresponding product is read from the product file stored in the RAM 13.
(ST5)... The print head (thermal head) 3a and the platen roller 3b of the printing unit 3 are actuated to start printing the print data on the mountless label paper 1a.
(ST6) ... Printing of predetermined print data is terminated.

(ST7)... After the printing is finished, the platen roller 3b of the printing unit 3 is driven and rotated to send the printing area 20 ′ and the subsequent cutting margin (non-printing part for separation) L out of the label issuing port 10. To do. In label issuance in the first issuance mode, the platen roller 3b (paper feeding portion) is set so that the cutting position X, which is a predetermined distance (cutting margin L) from the rear end of the print area 20 ′ in the label issuance direction, is positioned on the line of the cutter 4. The drive rotation is controlled. However, when the cutter 4 is not operated, the print label is separated from the mountless label paper 1a outside the label issuing port 10. Therefore, until the cutting position X, which is a predetermined distance (cutting allowance L) from the rear end of the printing area 20 ′ in the mountless label paper 1 a that has finished printing predetermined printing data, is sent out of the label issuing port 10. The platen roller 3b is driven to rotate (see FIG. 1A). In the drive control of the platen roller 3b (paper feeding portion), the label length along the label issuing direction (print area + distance between the blank areas before and after) is determined by the amount of print data of the label to be printed and issued, and The distance between the printing unit 3 (contact point between the print head 3a and the platen roller 3b) and the cutter 4, the distance from the cutter 4 to the label issuing port 10, the rotational speed of the platen roller 3b, and the like are known at the time of designing the apparatus. Therefore, by controlling the driving rotation of the platen roller 3b, the cutting position X can be fed out to a predetermined position outside the label issuing port 10 (a position at a predetermined distance from the label issuing port 10 toward the label issuing direction). it can.
(ST8)... The printed label sent out of the label issuing port 10 is manually cut within the range of the cutting allowance L by a bag or a cutting blade 19 (manual cutting part) fixed to the label issuing port 10. When the cutting blade 19 fixed to the label issuing port 10 is used for cutting, the platen roller 3b (paper feeding portion) is driven so that the cutting position X (cutting allowance) is located almost directly below the cutting blade 19. To control the delivery of the mountless label paper 1a. The cut print label is removed from the label receiver 5 and attached to the object.

The tip of the mountless label sheet 1a from which the mountless label 20 has been separated is moved from the contact position between the print head 3a of the printing unit 3 and the platen roller 3b to the feeding direction (downstream side) of the mountless label sheet 1a. Back feed to a slightly moved position and wait for the next label issuance (see FIG. 1B). Also for the back feed of the mountless label paper 1a, the distance from the printing unit 3 (contact point between the print head 3a and the platen roller 3b) to the position where the tip of the mountless label paper 1a is stopped is set in advance, and Since the distance (fixed) from the label issuing port 10 where the cutting position X (cutting margin) of the mountless label paper 1a is located is also known, by controlling the reverse rotation amount of the platen roller 3b, the mountless label paper 1a is controlled. The leading edge of the label sheet 1a can be back-fed to a predetermined position.

(ST10) ... Since there is no abnormality (failure) in the operation of the cutter 4, the cutter 4 operates normally to cut and issue the mountless label 20 [label issue in first issue mode].
(ST11) ... The print data of the corresponding product is read from the product file stored in the RAM 13.
(ST12)... The print head (thermal head) 3a and the platen roller 3b of the printing unit 3 are actuated to start printing the print data on the mountless label paper 1a.
(ST13) ... Printing of predetermined print data is terminated.
(ST14)... After the printing is finished, the platen roller 3b of the printing unit 3 is driven and rotated to print a predetermined distance from the rear end of the printing area 20 ′ in the mountless label paper 1a that has finished printing predetermined printing data ( Cutting allowance L) The cutting position X placed is transferred to the line of the cutter 4, and the cutter 4 is driven to cut the print label portion from the mountless label paper 1a (see FIG. 6A). The cut mountless label 20 is removed from the label receiver 5 and attached to the object.
(ST15) ... The tip of the mountless label sheet 1a from which the mountless label 20 has been separated is moved from the contact position between the print head 3a of the printing unit 3 and the platen roller 3b to the feeding direction (downstream side) of the mountless label sheet 1a. Back feed to a slightly moved position and wait for the next label issuance (see FIG. 6B).
(ST16) ... It is determined whether or not there is an instruction to issue the next label. If there is an issuance instruction (YES), the process returns to ST2, and if there is no issuance instruction (NO), the label issuance is terminated.

In the cutting and sending of the mountless label 20 shown in FIG. 4, the non-operation of the cutter 4 is automatically detected by the sensor (detection unit) 6, and the [label issue in the second issue mode] and [label issue in the first issue mode] However, it is also possible for the operator to visually determine an abnormality (failure, etc.) of the cutter 4 and to cut and send the mountless label 20 as [label issue in second issue mode]. It is. Hereinafter, the flow of cutting and sending the mountless label 20 when the operator visually detects an abnormality (failure or the like) of the cutter 4 will be described with reference to FIG.

If the label issuing key has been operated (YES), the process proceeds to ST110. When the issue key is not operated (NO), the above determination is repeated.
(ST110) ... The dotted line position of the mountless label sheet 1a from which the mountless label 20 has been separated is moved out from the contact position between the print head 3a and the platen roller 3b of the printing unit 3 (downstream side). Is fed back to the position slightly moved to wait for the next label issuance (see FIG. 1B). In this example, the back feed of the mountless label paper 1a is performed immediately before based on the next label issue instruction. However, regardless of the presence or absence of the next label issue instruction, the mountless label 20 portion is changed. After cutting outside the label issuing port 10, ST110 (back feed) may be performed immediately.

With the above configuration, when the non-operation (failure, etc.) of the cutter 4 (cutting unit) is automatically detected by the sensor (detection unit) 6 and the non-operation of the cutter 4 (cutting unit) is detected, the second issue If the operation of the cutter 4 (cutting section) is not detected normally in [Label issue mode], the label is issued in [Label issue in first issue mode]. For example, the cutter 4 (cutting) Even if the operation of the second printing mode is detected, the label printing work is continuously performed by [label printing in the second printing mode] without stopping the label printing work until the cutter 4 (cutting section) abnormality is repaired. be able to.
Even when an abnormality (failure) of the cutter 4 (cutting part) is detected by the operator's visual observation, the operation is switched to [label issuance in the second issuance mode] by the operation of the push button or the display / operation part 14. As is the case, the label issuing operation can be continued.
In [Label issue in the second issue mode], after printing predetermined print data, the amount of the mountless label paper 1a to be sent out of the label issue port 10 is set to a fixed amount. The amount of the cutting allowance (non-printing portion for separation) L following the portion is always constant, and a label whose appearance does not substantially change from the label issued in the first issue mode can be issued.
In [Label Issue in Second Issue Mode], the mountless label 20 portion is manually separated from the mountless label paper 1a, but a mark (dotted line in the embodiment) is printed at the cutting allowance (cutting position X). When displayed, the mountless label 20 can be clearly separated.
Further, when the cutting blade for separating the mountless label 20 portion from the mountless label paper 1a is disposed and fixed at the label issuing port 10, the mountless label 20 portion is easily and linearly separated without preparing a ridge. be able to.

The printer of the present invention is not limited to the illustrated embodiment, and can be changed as appropriate without departing from the scope of the present invention.
(1) In the embodiment (FIG. 3) in which the non-operation of the cutting unit is automatically detected by the detection unit (FIG. 3), when the detection unit detects the non-operation of the cutting unit, the detection unit outputs a detection signal. Although the example of automatically switching the operation of the paper feeding unit to the second issue mode has been shown, the present invention is not limited to this. For example, when the detection unit detects the non-operation of the cutting unit, the cutting unit is not operated (failure, etc.) May be displayed (notified) on a display unit or the like, and an operator who has viewed the notification (display) may manually switch to the second issue mode by operating the operation unit.
(2) In the embodiment (FIG. 3) in which the non-operation of the cutting unit is automatically detected by the detection unit (FIG. 3), after the cutting margin portion following the printing area portion is cut off from the label issuing port, the mountless label paper is immediately back-fed. Although an example is shown, the present invention is not limited to this, and the backfeed of the mountless label paper may be backfeeded immediately before the next label issuance according to the next label issuance instruction.
(3) In the embodiment (FIG. 3) in which the non-operation of the cutting unit is automatically detected by the detection unit (FIG. 3), the cutting mark (for example, the dotted line) is not printed in the cutting allowance (cutting position X). The dotted line printing in ST106 shown in FIG. 4 may be performed.
(4) In the embodiment, an “issue” key for issuing the next label is used as a trigger to back-feed the mountless label paper for the next label issue after the mountless label portion is cut off the label issue port. An example of operation is shown. However, the present invention is not limited to this. For example, when a weighing instrument is connected to a printer so as to communicate with each other, a weight signal is placed on the weighing instrument and output from the weighing instrument. When the CPU of the mountless label printer determines that is stable, backfeed of the mountless label paper may be performed.
(5) In the embodiment, the example in which the sensor (detection unit) 6 for detecting the non-operation of the cutter 4 (cutting unit) is arranged between the cutter 4 and the case 9 is shown. 4 may be disposed between the printing unit 3 and the printing unit 3 as long as the cutter 4 (cutting unit) can be inactivated.
(6) In the embodiment, the switching operation to [second issue mode] by the operator has been described by taking as an example a case where an abnormality of the cutting part is visually detected. However, the present invention is not limited to this, and the cutting part is Even if the cutter operates normally but the cutter is not sharp and the cut surface is rough, the cutting section can be stopped and the print label can be manually separated with a scissors or the like.
(7) In the embodiment, the example of the mountless label printer using the mountless label paper as the continuous paper is shown. However, the present invention is not limited to this, and an adhesive layer is formed on the surface opposite to the print surface as the continuous paper. A receipt printer that prints and issues a receipt using unrolled roll paper may also be used. In addition, when using mountless label paper, any type of paper that has an adhesive layer on the back side of the paper or a type of mountless label paper that generates adhesiveness when heated by a thermal head, etc. It may be.
(8) When the cutter (cutting unit) is unitized and the cutter unit is detachably disposed in the vicinity of the printing unit downstream, the cutter unit becomes inoperable due to failure or the like, and the cutter unit is removed. However, in this case, the printing head is arranged so that the downstream side is the outlet from the contact point between the print head and the platen roller constituting the printing unit, and the cutting position X is positioned downstream from the position. .
