Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram illustrating a configuration of a printing system 100 according to the present embodiment.
The printing system 100 includes a host computer 102 serving as a host device, and a printer 101 connected to the host computer 102 via a communication cable 103. This printing system 100 can be suitably used for issuing receipts and coupons in a POS system installed in a retail store such as a supermarket or a restaurant.

The host computer 102 transmits print data and control data to the printer 101 via the communication cable 103, and controls the printer 101 to print an image on a recording medium. When the printing system 100 is used in a POS system, print data including settlement information such as a purchased product name and a purchase price is transmitted from the host computer 102 to the printer 101.
The host computer 102 is configured by a computer system including a display 102a (display screen) for displaying various images and videos, a keyboard 102b operated by a user, and the like.
The printer 101 uses, for example, a roll paper 7 in which a label paper without a mount (release paper) is wound in a roll shape as a recording medium, and heat is applied to the printing surface of the roll paper 7 by a thermal head 8 (FIG. 3). It is configured as a so-called roll paper printer for printing.

  As shown in FIG. 1, the printer 101 has a substantially box-shaped exterior configured by assembling a roll paper cover 2 (lid) and a cutter cover 3 to the main case 1, and the upper surface of the printer 101 has a roll paper after printing. 7 is formed. The paper discharge port 16 is provided with a manual cutter 4 having a cutting blade. The roll paper 7 is pressed against the cutting blade of the manual cutter 4 and can be cut by hand. Further, on the front surface of the printer 101, various switches such as a power button and operation switches and various indicators are provided.

FIG. 2 is a perspective view showing a frame configuration of the printer 101.
The printer 101 includes a base frame 24 formed in a box shape as a main body frame 20 </ b> A, and a left side frame 21 and a right side frame 22 disposed on the base frame 24 so as to face each other. A roll paper holder 26 that holds the roll paper 7 in a rollable state is disposed at the rear part of the left side frame 21 and the right side frame 22. Above the roll paper holder 26, the roll paper cover described above is provided. A roll paper cover frame 25 for fixing 2 is provided. The roll paper cover 2 is configured so as to be able to be opened and closed together with the roll paper cover frame 25 with the hinge 27 as a fulcrum. When the roll paper cover 2 is opened, the roll paper holder 26 is opened and the roll paper 7 is set. It becomes possible. On the other hand, an auto cutter unit 9 as a cutter mechanism is disposed in front of the left side frame 21 and the right side frame 22.

FIG. 3 is a cross-sectional view of the printer 101.
The printer 101 includes a head frame 80 spanned between the left side frame 21 and the right side frame 22, and the thermal head 8 is disposed on the head frame 80. The thermal head 8 includes a large number of heating elements (not shown) arranged in the longitudinal direction (width direction of the roll paper 7), and heats the roll paper 7 in contact with the printing surface of the roll paper 7, thereby An image containing is recorded. A main board 10 which is a control board for controlling the entire printer 101 is disposed on the base frame 24 in a state of being sandwiched between the front board cover 12 and the rear board cover 13. The main board 10 is connected to an interface board 11 that enables various devices to be connected.

  A platen 5, which is a round platen, is disposed at a position facing the thermal head 8, and this platen 5 also serves as a transport mechanism for the roll paper 7. That is, the platen 5 is urged toward the thermal head 8 and is rotatably provided by a paper feed motor 48 (FIG. 4). The platen 5 and the thermal head 8 are drawn from the roll paper holder 26. The leading end of the roll paper 7 is sandwiched. As the platen 5 rotates, the roll paper 7 is sequentially pulled out from the roll paper holder 26 along the transport path S, printed by the thermal head 8 and discharged from the paper discharge port 16. The auto cutter unit 9 is disposed at the paper discharge port 16. When driven by a drive motor (not shown), the auto cutter unit 9 includes a movable blade 94 and a fixed blade 95 disposed with the conveyance path S interposed between the movable blade 94 and moves the movable blade 94. Thus, the roll paper 7 discharged from the paper discharge port 16 is cut. The cut and printed roll paper 7 is issued as a receipt or a coupon.

  Further, the roll paper holder 26 is provided with a near-end detector 17 that detects that the remaining amount of roll paper 7 is low, and a detection signal of the near-end detector 17 is input to the main board 10. The near-end detector 17 includes a limit switch (not shown) that is turned on according to the height position of the roll core of the roll paper 7 in the roll paper holder 26. This limit switch is set to turn on when the height of the core is lowered to a predetermined position as the roll paper 7 is consumed, that is, when the remaining amount of the roll paper 7 reaches a predetermined amount. The limit switch detection signal is input to the main board 10. Further, the remaining amount of the roll paper 7 detected as the near end can be varied by adjusting the height position of the winding core at which the limit switch is turned on.

FIG. 4 is a block diagram illustrating a functional configuration of the printing system 100.
The printer 101 includes a control unit 40 configured by providing a CPU, ROM, and RAM on the main board 10. Print data or the like is supplied from the host computer 102 to the control unit 40 via the interface 42. The near end detector 17 is connected to the input side of the control unit 40, and the control unit 40 detects the near end of the roll paper 7 based on the input signal from the near end detector 17. The control unit 40 is connected to a nonvolatile memory 43 that stores firmware 44 as a control program. The thermal head 8, the paper feed motor 48, and the auto cutter unit 9 are connected to the output side of the control unit 40 via a head driver 45, a motor driver 46, and an auto cutter driver 47, respectively.

The control unit 40 centrally controls the printing operation on the roll paper 7, and includes a roll paper remaining amount monitoring unit 51 and a near-end print control unit 53.
The roll paper remaining amount monitoring unit 51 monitors the amount of paper feed of the roll paper 7 after the near end is detected by the near end detector 17, and includes a paper feed counter 61. The paper feed counter 61 monitors the total amount of paper feed of the roll paper 7 by counting the steps for controlling the drive of the paper feed motor 48 in the feed direction and calculating the total number of steps (cumulative value).

  When the near end is detected by the near end detector 17, the near end print control unit 53 controls to print a near end pattern 65 as a mark indicating the near end near the cutting position of the roll paper 7 to be printed thereafter. And includes a pattern changing unit 63. The pattern changing unit 63 changes the image when the near end pattern 65 (FIG. 6) is printed based on the remaining amount of the roll paper 7, and thereby the remaining amount of the roll paper 7 is changed from the near end pattern 65. The user can grasp it.

In the printing system 100, when the printed material is a predetermined printed material such as a coupon, for example, it can be set to prohibit printing of the near-end pattern 65 on the printed material. More specifically, setting data 67 including a printed matter that prohibits printing of the near-end pattern 65 as a setting value is stored in the host computer 102. When the host computer 102 prints the printed matter specified by the setting data 67, the host computer 102 includes prohibition information indicating prohibition of printing of the near-end pattern 65 in the print data and transmits it to the printer 101. When the prohibition information is included in the print data, the control unit 40 prohibits printing of the near-end pattern 65 even when the near-end detector 17 detects the near-end. Thus, for example, when the printed material is a normal receipt, the near-end pattern 65 is printed, and when the printed material is a specific printed material such as a value-added coupon, the near-end pattern 65 is not printed. .
The host computer 102 is configured to store the setting data 67 in which the printed matter that prohibits printing of the near-end pattern 65 is stored. However, the present invention is not limited to this, and may be configured to be stored in advance in the RAM of the printer 101.

Next, the printing operation of the printer 101 will be described with reference to FIG.
When the power is turned on, the control unit 40 enters a standby state (step S1), and waits until print data is received from the host computer 102 (step S2: No). When print data is received from the host computer 102 during the standby state (step S2: Yes), the control unit 40 performs printing on the roll paper 7 based on character data and image data to be printed included in the print data. (Step S3). Then, the controller 40 determines whether or not the near end of the roll paper 7 has been detected by the near end detector 17 before feeding the paper for paper discharge (step S4).

  If the near end is not detected (step S4: No), the remaining amount of the roll paper 7 is sufficient, and the near end pattern 65 is not printed on the roll paper 7 and is discharged as it is. That is, the control unit 40 drives the paper feed motor 48 to convey the roll paper 7. At this time, a position separated by a predetermined length from the position of the last line printed on the roll paper 7 is defined as the cutting position K, and the control unit 40 makes the cutting position K cut by the auto cutter unit 9. (Step S5), and the auto cutter unit 9 is driven to cut the roll paper 7 at the cutting position K (step S6). As a result, as shown in FIG. 6A, the roll paper 7 is cut at a cutting position K that is a predetermined distance away from the last line 75A of the print location 75 indicated by hatching, and the cut printed matter is issued as a receipt or a coupon, for example. Is done.

  On the other hand, when the near end is detected (step S4: Yes), the control unit 40 includes the prohibition information in the print data received from the host computer 102 as to whether printing of the near end pattern 65 is prohibited. Judgment is made based on whether or not (step S7). If printing of the near-end pattern 65 is prohibited (step S7: Yes), the control unit 40 advances the processing procedure to step S5, and performs normal printing without printing the near-end pattern 65.

  When the printing of the near end pattern 65 is not prohibited (step S7: No), the control unit 40 performs the following process to notify the user of the near end of the roll paper 7 by printing the near end pattern 65. That is, the controller 40 feeds the paper so that the cutting position K is positioned on the thermal head 8 in order to print the near-end pattern 65 in the vicinity of the cutting position K of the roll paper 7 after printing (step S8). Then, the pattern change unit 63 receives the detection value of the total amount of roll paper 7 (total amount of paper feed) printed after the near end is detected from the roll paper remaining amount monitoring unit 51, and printing should be performed based on this total amount. The near end pattern 65 is determined (step S9).

  More specifically, in the present embodiment, the remaining amount of the roll paper 7 when starting to be detected as a near end is set as an initial value, and the remaining amount up to, for example, 30% (70%) is “high” with respect to this initial value. The remaining amount from 30% (70%) to 70% (30%) of the initial value is classified as “Medium”, and the remaining amount from 70% (30%) to the initial value is used as “Low”. is doing. As shown in FIG. 6, different near-end patterns 65 are associated with each remaining amount category. In the example shown in the figure, the horizontal line 66 is used as the near-end pattern 65. As shown in FIGS. 6B to 6D, the smaller the remaining amount of the roll paper 7, the more the horizontal line 66 becomes. A near-end pattern 65 having a longer length is associated with each remaining amount category. The data of these near-end patterns 65 is stored in, for example, the RAM of the control unit 40 or included in the firmware 44 in advance.

In step S9, the pattern changing unit 63 is based on the total amount of roll paper 7 printed after the near end is detected and the remaining amount (initial value) of the roll paper 7 when the near end is detected. Then, it is specified whether the remaining amount of the roll paper 7 corresponds to “high”, “medium”, or “low”, and the near-end pattern 65 corresponding to the specified remaining amount is specified. Note that the remaining amount of the roll paper 7 when starting to be detected as the near end is preliminarily defined in advance based on the height position of the roll core of the roll paper 7 detected by the near end detector 17, and this prescribed value is , And used as an initial value of the remaining amount of the roll paper 7 when the near end is detected.
Next, the control unit 40 prints the near-end pattern 65 determined by the pattern changing unit 63 (step S10), and then proceeds to the above step S5 to feed and cut the roll paper 7.

  As a result of such processing, as shown in FIG. 6, when the near end is not detected, that is, when the remaining amount of the roll paper 7 is sufficient, the near end is set at the cutting position K of the roll paper 7 after printing. When the pattern 65 is not printed (FIG. 6A) and a near end is detected thereafter, a horizontal line 66 having a length corresponding to the remaining amount of the roll paper 7 at that time is cut as the near end pattern 65. It is printed at the position K (FIGS. 6B to 6D).

As described above, according to this embodiment, when the near end of the roll paper 7 is detected by the near end detector 17, the mark indicating the near end at the cutting position K of the roll paper 7 after normal printing on the roll paper 7. The near-end pattern 65 is printed. With this configuration, the user of the printer 101 can grasp the near end of the roll paper 7 by the appearance of the near end pattern 65.
Furthermore, since the near end of the roll paper 7 is notified by printing the near end pattern 65, it is not necessary to previously mark the roll paper 7 with a mark indicating the near end in the manufacturing process as in the prior art. As a result, the productivity of the roll paper 7 is enhanced, and the label paper without a mount is difficult to pre-mark the mark indicating the near end because of low affinity with the conventional mark-applying paint indicating the near end. Even when the roll paper 7 is used, the user can be surely notified of the near end.

  In addition, according to this embodiment, since the position where the near end pattern 65 is printed is limited to the cutting position K of the roll paper 7, a mark indicating the near end is attached in advance along the edge of the roll paper 7. Thus, compared to the conventional method of notifying the near end, the near end pattern 65 which is a mark indicating the near end is not conspicuous, so that a third party can hardly feel the near end notification unpleasantly. Furthermore, when printing is performed over the entire width of the roll paper 7, if a mark indicating a near end is attached in advance along the edge of the roll paper 7, a situation may occur in which the printing overlaps with this mark. On the other hand, according to this embodiment, since the near end pattern 65 is printed at the cutting position K after printing on the roll paper 7, the near end pattern 65 is prevented from overlapping other prints, and the quality of the printed matter is improved. There is no loss.

  Further, according to the present embodiment, the pattern of the near-end pattern 65 is changed according to the remaining amount of the roll paper 7. With this configuration, the user can grasp the remaining amount of the roll paper 7 based on the pattern of the near end pattern 65 after the near end is detected. In addition, the user can replace the roll paper 7 with the timing when the roll paper 7 has been used up enough to prevent the roll paper 7 from being short of paper.

In addition, according to the present embodiment, it is possible to set whether to print the near-end pattern 65 according to the printed matter. With this configuration, it is possible to selectively use the near-end pattern 65 according to the printed material, such as printing / not printing the near-end pattern 65. For example, the near-end pattern 65 is printed only when printing a printed matter whose value may be lost (for example, a coupon) or a printed matter that feels troublesome when the near-end pattern 65 is printed together. It is easy to use such that the pattern 65 is not printed.
Note that whether or not to print the near-end pattern 65 may be set without being limited to the printed matter. According to this, it is possible to use such that the near-end pattern 65 is not always printed on the roll paper 7 for the reason of using, for example, roll paper with a pre-marked near-end mark.

  In addition, embodiment mentioned above shows the one aspect | mode of this invention to the last, and a deformation | transformation and application are arbitrarily possible within the scope of the present invention.

  For example, in the above-described embodiment, the configuration in which the near-end pattern 65 is printed at the cutting position K of the roll paper 7 is exemplified, but the present invention is not limited thereto. That is, the printing position of the near-end pattern 65 is arbitrary as long as it is behind the printing place 75 and in the vicinity of the cutting position K. For example, as shown in FIG. Alternatively, the near end pattern 65 may be printed. Further, the printing position of the near-end pattern 65 is not limited to the center of the roll paper 7 but may be near the edge of the roll paper 7 as shown in FIG.

  Further, as the near end pattern 65 which is a mark indicating the near end, an arbitrary image such as a figure, a symbol, or a character can be used. At this time, in addition to the configuration in which one figure such as the horizontal line 66 is used as the near end pattern 65, the near end pattern 65 may be configured by a combination of a plurality of figures as shown in FIG. 7C, for example. At this time, the number and type of combinations of figures constituting the near-end pattern 65 may be varied according to the remaining amount of the roll paper 7. For example, as shown in FIG. 7D, an arbitrary character string such as a print issuer may be used as the near-end pattern 65, for example.

  Further, the configuration is not limited to the configuration in which the near-end pattern 65 is printed between the printing location 75 and the cutting position K. For example, as shown in FIG. 7E, the roll paper 7 after the cutting position K, that is, after cutting. The near end pattern 65 may be printed at the head position L. At this time, the near-end pattern 65 is printed between the leading position L of the roll paper 7 and the leading line 75B of the print location 75.
