FIG. 3 is a functional block diagram showing an example of the electrical configuration of the printing apparatus 100 which is the mountless label printer shown in FIG.
As shown in FIG. 3, the printing apparatus 100 includes a control unit 9 (CPU), a flash memory 10, a RAM 11, a display / operation unit 12, an interface circuit 13, a stepping motor 14 that rotates the platen roller 3b, a thermal head (printing). A head 3a), a cutter driving motor 15, a paper detection sensor 6, a label detection sensor 7 as a label detection means, and a reader / writer 16 as a non-contact wireless tag communication unit.

  The control unit 9 (CPU) is a central processing unit that executes a program stored in a storage unit such as the flash memory 10 or the RAM 11 and controls the operation of the printing apparatus 100 such as a mountless label printer.

The flash memory 10 and the RAM 11 as storage units store control programs, data, and the like.
The flash memory 10 is a read-only memory that stores a control program of the printing apparatus 100, control data, and the like.

  The RAM 11 has a work area for temporarily calling and processing data. The work area includes a dot development area for developing print data into dot data, a call format area for calling and storing one format data from the label format file shown in FIG. 4, and a product data shown in FIG. It has a call product area to be stored.

  The RAM 11 includes 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 like based on the detection result of the label detection sensor 7. A file or the like in which the determination contents are set is stored, and is backed up by a battery so that the file is retained even when the power is turned off.

  As shown in FIG. 4, the determination file based on the detection result of the label detection unit 7 is a mountless label sheet if the detection data of the label detection unit 7 is the presence / absence detection of the mountless label sheet 1a before the cutter 4 is operated. If it is determined whether or not 1a is wound around the platen roller 3b and the detection data of the label detection means 7 is detection of the presence or absence of the mountless label L after the operation of the cutter 4, the mountless label L sent to the label receiver 5 is detected. The presence / absence of removal of the label is detected, and it is determined whether or not the next label is issued.

  More specifically, when the presence / absence detection of the mountless label paper 1a of the label detecting means 7 before the cutter 4 is operated is “◯ (Yes)”, the printed mountless label paper 1a is normally placed on the label receiver 5. In the case of “× (none)”, it is determined that the printed mountless label paper 1a has not been sent onto the label receiver 5, that is, has been wound around the platen roller 3b.

  The display / operation unit 12 is an input device for operating the printing apparatus 100 (mountless label printer), and is a touch panel integrated with the display unit, and displays various menu screens and data. It is a liquid crystal display.

A stepping motor 14 that drives and rotates the platen roller 3b, a thermal head (printing head 3a), and a cutter driving motor 15 constitute a printing unit of a label issuing unit, and a mountless label based on a command from the control unit 9 (CPU) A product name, a price, a unit price, a barcode, and the like are printed on the paper 1a, and the printed paperless label paper 1a is cut into sheets by a cutter 4 to issue a paperless label L.
Note that the control unit 9 may count the number of rotations of the platen roller 3b that has been driven and rotated by an encoder or the like, calculate a distance based on the count value, and use it as a travel distance. When a stepping motor is employed as the drive source for the platen roller 3b, the control unit 9 may calculate a distance based on the number of stepping motors and use it as a travel distance.
Further, the control unit 9 can determine whether or not the calculated travel distance is correct by comparing the travel distance calculated in the current label issuance with the label length of the print image printed this time.
When a paper jam or the like occurs during the label issuance, the control unit 9 performs a comparison determination similar to the above to determine the travel distance up to the current time when the error has occurred, and determines whether or not the current travel distance is correct. If there is a difference in length in the determination result, the control unit 9 adopts the travel distance calculated based on the rotational speed of the platen roller 3b that has been driven and rotated as the travel distance up to the present time. By doing so, the control unit 9 can acquire a value close to the correct travel distance (calculated travel distance).

  The paper detection sensor 6 detects the presence or absence of the mountless label paper 1a supplied to the printing unit 3, and the drive of the print head (thermal head) 3a and the platen roller 3b is controlled by the output signal.

  The label detection sensor 7 (label detection means) detects the presence or absence of the mountless label paper 1a or the mountless label L on the label receiver 5, and the control unit 9 drives and stops the printing unit 3 based on the detection result. To control the operation.

The reader / writer 16 is a contactless wireless tag communication unit, and performs data communication with the contactless wireless tag 18 under the control of the control unit 9. Specifically, the reader / writer 16 writes and reads data to and from the non-contact wireless tag 18 provided in the hollow tube 1p of the paper roll 1 (label roll) set in the roll loading unit 2. .
Data to be written includes lot number (manufactured lot number of linerless label roll), printer information (printing device model number, identification information, etc.), issuance date (date of printing), operator information (operation that performed the operation) Identification information, name, etc.), issuance data (printing instruction data, etc.), format information (format identification number, etc.), error information (error details data including error number, etc.), information related to issuance (number of issued sheets (10 Sheet / 10 sheets), the length in the label issuing direction based on the print data, the travel distance to the current time on the label roll, and the like.
Based on an instruction to issue 10 sheets, the number of issued sheets is 10/10 sheets when 10 sheets are correctly issued, and 3/10 sheets when only 3 sheets can be printed.

The control unit 9 performs a process of writing this data (printing information) to the non-contact wireless tag 18 via the reader / writer 16 every time a sheet-like sheet (linerless label) is issued.
Further, the controller 9 can read the latest print information (issue information) from the non-contact wireless tag 18 by the reader / writer 16 before performing new printing, and can correctly print the print data to be issued next. For example, when there is a history in which an error has occurred in the most recent printing in the printing apparatus 100, it is possible to issue a linerless label based on the error information. It is determined whether or not.

  Further, the non-contact wireless tag 18 stores the travel distance of the label roll to which the non-contact wireless tag 18 is attached. For this reason, the control unit 9 determines that the value obtained by subtracting the travel distance of the label roll from the basic total length of the linerless label roll stored in the non-contact wireless tag 18 or the printing apparatus (printer) is the remaining label roll. It is determined whether or not it is equal to or longer than the length in the issuance direction of print data to be printed. The control unit 9 determines that printing is possible if the remaining amount of the calculation result is greater than or equal to the length in the print data issuance direction, and cannot be issued if the remaining amount of the calculation result is less than the length of the print data issuance direction. Printing is prohibited, and a notification is made via notification means (display / operation unit, etc.) that the paper roll 1 (linerless label roll), which is a printing medium, needs to be replaced. In addition, when writing is performed including the remaining amount of the label roll in the issuance information (history information), the remaining amount of the label roll in the issuance information (history information) read from the non-contact wireless tag 18 will be printed. Whether or not printing is possible is determined based on whether or not the print data is longer than the length in the issuance direction. Further, when the value obtained by subtracting the travel distance in the label roll from the basic total length of the label roll is approximate or equal to the remaining amount of the label roll in the issuance information (history information), The remaining amount of the label roll in the issue information (history information) may be determined to be a correct value, and may be determined to be incorrect in other cases.

  The control unit 9 stores the latest print information (history information) read from the non-contact wireless tag 18 provided on the paper roll 1 via the reader / writer 16 as error information (unique ID information of each printing apparatus and the like). If the unique ID information of the current printing apparatus 100 in which the paper roll 1 is set is different from the unique ID information of the printing apparatus included in the error information, it is based on the read print information. The label that could not be printed is printed.

The printing apparatus 100 according to the embodiment of the present invention is based on all print information read from the non-contact wireless tag 18 attached to the hollow tubular body 1p by the control unit 9 via the reader / writer 16. The data can be organized for each error type, and the print history tabulation can be displayed on the display / operation unit 12 of the printing apparatus 100.
Thereby, the printing error in the paper roll 1 (linerless label roll) can be easily grasped. In addition, it is easy to determine whether there is a problem in the operation settings of the operator, a problem in the printing apparatus 100 itself, or a problem in the paper roll, and the cause can be properly grasped. For this reason, problems such as errors can be solved early.

  In step ST20, the control unit 9 performs processing for generating print data based on the print instruction information.

  In step ST30, the control unit 9 determines the travel distance in the label roll from the basic total length of the paper roll 1 (linerless label roll) stored in the non-contact wireless tag 18 based on the travel distance in the label roll in the history information. Is subtracted to obtain the remaining amount of the label roll. Note that the basic total length of the paper roll 1 (linerless label roll) is not limited to being stored in the non-contact wireless tag 18, but the basic length for each type of the paper roll 1 (linerless label roll) on the printing device (printer) side. The total length may be stored.

  In step ST40, the control unit 9 determines whether or not the obtained remaining amount is equal to or longer than the length in the issuance direction of print data to be printed (whether or not it is a printable remaining amount). The control unit 9 proceeds to the process of step ST50 when the obtained remaining amount is equal to or longer than the length in the print data issuance direction, and proceeds to step ST70 when the remaining amount is less than the length in the print data issuance direction. Proceed to

  In step ST50, the control unit 9 performs printing by the printing unit 3 based on the print data, and when the printing is completed, the process proceeds to step ST60.

  In step ST60, the control unit 9 performs a process of writing issue information (history information) to the non-contact wireless tag 18 via the reader / writer 16, and ends a series of processes. The issuance information (history information) to be written is written including the travel distance of the label roll including the currently printed label length, but the label roll used for the current issuance from the remaining amount of the label roll obtained in step ST30. May be further subtracted, and the remaining amount of the label roll at the present time may be included in issuance information (history information) and written.

  In step ST70, the control unit 9 prohibits the printing process by the printing unit 3 because it cannot be issued, and notifies the fact that the paper roll 1 (linerless label roll) needs to be replaced via a notification unit such as the display / operation unit 12. The notification process is performed, and the series of processes ends.

  As described above, the paper roll 1 (linerless label roll) as a printing medium according to the embodiment of the present invention is a print formed by winding a belt-like paper around a hollow tube used in the printing apparatus 100. When a non-contact readable / writable non-contact wireless tag 18 is attached to the hollow tube 1p as a medium, and when the wound belt-like sheet is issued by the printing apparatus 100 as a sheet-like sheet Is issued or read by the reader / writer 16 which is a non-contact wireless tag communication unit of the printing apparatus 100.

Based on the obtained remaining amount, it is determined whether or not to issue a sheet of paper to be issued next. If the determination result indicates that the sheet roll cannot be issued, a notification that the paper roll needs to be replaced is displayed / operated unit 12 or the like. This is done through the notification means.
For this reason, it is possible to provide a print medium capable of grasping an accurate remaining amount for each paper roll and detecting an issuance history in the paper roll from the non-contact wireless tag 18 provided on the paper roll. it can. Moreover, the printing apparatus 100 using the printing medium (paper roll 1 such as a linerless label roll) can be provided.

  Further, even when the paper roll 1 that is a consumable mounted on the printing apparatus 100 is replaced with another paper roll, it is based on the issuance history recorded on the non-contact wireless tag 18 of the paper roll. , Accurately grasp the remaining amount of paper roll, and notify the replacement of consumables at an appropriate timing when the remaining amount of paper roll is insufficient compared to the sheet of paper to be issued next Can do.

Further, the control unit 9 reads the issuance history recorded in the non-contact wireless tag 18 via the reader / writer 16 as the non-contact wireless tag communication unit, and based on the issuance history, at the time of printing by the paper roll Defects can be grasped for each issue.
For this reason, it is possible to easily understand whether the operator has made an error in operation settings, a consumable lot defect, or an error in the printing apparatus, and investigate the cause. That is, it is possible to provide a printing medium that can easily perform work improvement, countermeasures, and countermeasures, and a printing apparatus 100 using the printing medium.

Specifically, the storage unit of the non-contact wireless tag 18 provided in each paper roll 1 stores the tag ID information unique to the non-contact wireless tag 18 and is loaded in the roll loading unit 2 of the printing apparatus 100. In this case, ID information unique to the printing apparatus 100 and issuance information including issuance error information and issuance history are stored in association with each other.
For example, the paper roll 1 is set in the first printing apparatus 100A, and a printing error such as paper clogging or uneven printing occurs during printing. Next, the paper roll 1 is set in the second printing apparatus 100B and printed. When a printing error such as a similar paper or printing unevenness sometimes occurs, the control unit 9 of the second printing apparatus 100B can determine that the error is in the paper roll 1 itself.
Specifically, the control unit 9 of the first printing apparatus 100A on which the paper roll 1 is set sends the print error information and the unique ID information of the printing apparatus 100A to the contactless wireless of the paper roll 1 when a printing error occurs. It is stored in association with the tag 18. The storage unit of the non-contact wireless tag 18 stores print error information, unique ID information of the printing apparatus 100A, and tag ID information in association with each other.
When the paper roll 1 is set in the second printing apparatus 100B, the control unit 9 of the second printing apparatus 100B reads the printing error information and the printing apparatus read from the storage unit of the non-contact wireless tag 18 when a printing error occurs. If it is determined that the number of occurrences of a similar printing error (for example, paper jam) is greater than the prescribed number based on the unique ID information of 100A and the tag ID information, the paper roll 1 itself may be defective. It is determined that there is a characteristic, and a notification to that effect is given to the operator.
When the paper roll 1 is set in the second printing apparatus 100B and printing processing is performed and no printing error occurs, the control unit 9 of the second printing apparatus 100B reads from the storage unit of the non-contact wireless tag 18 Based on the read print error information, the unique ID information of the printing apparatus 100A, and the tag ID information, it is determined that there is a high possibility of a printing error in the printing unit 3 of the printing apparatus 100A, and notification means for this For example, the operator is notified.
