However, when the transfer of the print medium is performed by the DC motor, the transfer of the print medium cannot be stopped immediately, and the inertial transfer of the print medium may occur. Therefore, if the stop process is performed during the print process, the print process is interrupted, and then the print process is restarted, a gap is generated in the print result due to the inertial transfer of the printed medium generated during the stop process.

Hereinafter, a heat-sensitive label printer using the heat-sensitive tape 21 will be described as an example, but a heat-transfer type label printer using an ink ribbon may be used. The printing device 1 acquires print data such as a print pattern from the computer 100. The computer 100 creates a print pattern for printing on the thermal tape 21 based on the user's operation.

As shown in FIG. 1, the printing apparatus 1 includes an apparatus housing 2, an openable / closable lid 3, and a window 4. The device housing 2 is formed with a discharge port 2a for discharging the heat-sensitive tape 21 to the outside of the device housing 2. Further, the device housing 2 is provided with a power cord connection terminal, an external device connection terminal functioning as an interface unit 11 (see FIG. 3), a storage medium insertion port, and the like.

The lid 3 is arranged on the side of the device housing 2. The user can open the lid 3 as shown in FIG. 2 by pressing the button 3a to release the lock mechanism. A window 4 is formed on the lid 3 so that it can be visually confirmed whether or not the heat-sensitive tape 21 is housed in the printing apparatus 1 even when the lid 3 is closed.

As shown in FIG. 2, the device housing 2 includes a medium adapter accommodating portion 2b, a platen roller 5, and a thermal head 6. The medium adapter 20 is accommodated in the medium adapter accommodating portion 2b. Further, the apparatus housing 2 includes a full cutter 7, a half cutter 8, and a photo sensor 9 between the discharge port 2a from which the heat-sensitive tape 21 is discharged and the thermal head 6. The half cutter 8, the full cutter 7, and the photo sensor 9 are arranged in this order from the discharge port 2a side.

The medium adapter 20 accommodates the thermal tape 21. The heat-sensitive tape 21 housed in the medium adapter 20 is housed in a state of being wound in the longitudinal direction and having a cylindrical shape, for example. The medium adapter 20 is designed according to the tape width of the thermal tape 21. In this example, the medium adapter 20 is a medium adapter for a tape having a tape width of 6 mm.

In the printing apparatus 1, the medium adapter 20 accommodating the thermal tape 21 is accommodated in the printing apparatus 1, so that the thermal tape 21 is accommodated in the printing apparatus 1. The printing apparatus 1 can accommodate media adapters corresponding to different tape widths. Specifically, the printing apparatus 1 can accommodate, for example, a medium adapter 20 for 6 mm tape, a medium adapter for 12 mm tape, a medium adapter for 18 mm tape, and the like, in addition to the medium adapter 20 for 6 mm tape shown in FIG. ..

The heat-sensitive tape 21 has, for example, a five-layer structure in which a separator, an adhesive layer, a base material, a coloring layer, and a protective layer are laminated in this order from the lower layer. The separator is detachably attached to the substrate so as to cover the adhesive layer. The material of the separator is, for example, paper, but the material is not limited to paper, and PET (polyethylene terephthalate) may be used. The adhesive layer is an adhesive material applied to the base material. The material of the base material is, for example, colored PET. The color-developing layer is a heat-sensitive color-developing layer that develops color by heating with heat energy. The material of the protective layer is, for example, transparent PET. The structure of the heat-sensitive tape 21 is not limited to such a five-layer structure. For example, the heat-sensitive tape 21 may have no protective layer and the color-developing layer may be exposed.

The platen roller 5 is a transport unit for transporting the heat-sensitive tape 21. The platen roller 5 is rotated by the rotation of the transport motor 32 (see FIG. 3). The platen roller 5 conveys the heat-sensitive tape 21 in the transport direction by rotating the heat-sensitive tape 21 unwound from the medium adapter 20 while holding it between the thermal head 6 and the thermal head 6.

The thermal head 6 is a printing unit that prints on the thermal tape 21. The thermal head 6 has a plurality of heat generating elements 6a (see FIG. 3) arranged in the main scanning direction orthogonal to the transport direction of the heat sensitive tape 21, and by heating the heat sensitive tape 21 by the heat generation element 6a, one line at a time.

The full cut is an operation of cutting all the layers constituting the heat-sensitive tape 21 along the width direction of the heat-sensitive tape 21.

The half cutter 8 is a second cutting device that cuts the heat-sensitive tape 21, and cuts the heat-sensitive tape 21 by half-cutting the heat-sensitive tape 21. The half-cut is an operation of cutting the layers of the heat-sensitive tape 21 other than the separator along the width direction.

The photo sensor 9 is a sensor arranged on the transport path of the heat-sensitive tape 21 in order to detect the tip of the heat-sensitive tape 21. The photo sensor 9 includes, for example, a light emitting element and a light receiving element. The light emitting element is, for example, a light emitting diode, and the light receiving element is, for example, a photodiode. The photo sensor 9 detects the reflected light of the light emitted from the light emitting element by the light receiving element, and outputs a signal to the control circuit 10 (see FIG. 3) described later. The control circuit 10 detects the tip of the heat-sensitive tape 21 based on, for example, a change in the amount of reflected light detected by the light receiving element. The photo sensor 9 is not limited to the photo reflector that detects the reflected light of the light emitted from the light emitting element. The photo sensor 9 may be a photo interrupter in which a light emitting element and a light receiving element are arranged so as to face each other.

FIG. 3 is a block diagram showing a hardware structure of the printing apparatus 1. In addition to the above-mentioned components, the printing device 1 includes a control circuit 10, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a head drive circuit 14, a thermista 15, and a transfer, as shown in FIG. It includes a motor drive circuit 31, a transfer motor 32, an encoder 33, a cutter motor drive circuit 34, a cutter motor 35, and a tape width detection switch 36.

The control circuit 10 is a control unit including a processor such as a CPU (Central Processing Unit). The control circuit 10 controls each part of the printing apparatus 1 (for example, the platen roller 5 and the thermal head 6) by expanding and executing the program stored in the ROM 12 in the RAM 13.

The ROM 12 stores a program for performing the process shown in FIG. 4 described later, and various data necessary for executing the program (for example, a font, an inertial transport amount table described later, and the like). The RAM 13 is a work memory used for executing a program. The computer-readable recording medium that stores the programs and data used for processing in the printing apparatus 1 includes physical (non-temporary) recording media such as ROM 12 and RAM 13.

The head drive circuit 14 controls the energization of the heat generating element 6a of the thermal head 6 based on the print data and the control signal under the control of the control circuit 10. The thermal head 6 has a plurality of heat-generating elements 6a arranged in the main scanning direction, and by heating the heat-sensitive tape 21 with the heat-generating elements 6a, printing is performed on the heat-sensitive tape 21 line by line. That is, in the printing device 1, the control circuit 10 is a control unit that controls the thermal head 6 by controlling the energization of the heat generating element 6a via the head drive circuit 14.

The thermistor 15 is embedded in the thermal head 6. The thermistor 15 is a temperature detection unit that detects the temperature of the thermal head 6.

The transport motor drive circuit 31 drives the transport motor 32 under the control of the control circuit 10. The transport motor 32 is a DC motor. The transport motor 32 rotates the platen roller 5.

The platen roller 5 is a transport unit that is rotated by the driving force of the transport motor 32 and transports the heat-sensitive tape 21 along the longitudinal direction (sub-scanning direction, transport direction) of the heat-sensitive tape 21. The platen roller 5 pays out the heat-sensitive tape 21 from the medium adapter 20 and conveys the heat-sensitive tape 21.

That is, in the printing device 1, the control circuit 10 is a control unit that controls the platen roller 5 by controlling the transfer motor 32 via the transfer motor drive circuit 31.

The encoder 33 outputs a signal corresponding to the drive amount (rotation amount) of the transfer motor 32 or the platen roller 5 to the control circuit 10. The encoder 33 may be provided on the rotating shaft of the transport motor 32, or may be provided on the rotating shaft of the platen roller 5. The control circuit 10 can specify the transfer amount of the heat-sensitive tape 21 based on the signal from the encoder 33, and can also measure the transfer speed of the heat-sensitive tape 21.

The cutter motor drive circuit 34 drives the cutter motor 35 under the control of the control circuit 10. The full cutter 7 is operated by the power of the cutter motor 35 to cut all the layers of the thermal tape 21 to create a tape piece. The half cutter 8 is operated by the power of the cutter motor 35 and cuts layers other than the separator in the thermal tape 21.

The tape width detection switch 36 is a switch for detecting the width of the heat-sensitive tape 21 accommodated in the medium adapter 20 based on the shape of the medium adapter 20, and is provided in the medium adapter accommodating portion 2b. A plurality of tape width detection switches 36 are provided in the medium adapter accommodating portion 2b. The media adapter 20 corresponding to different tape widths is configured to press the plurality of tape width detection switches 36 in different combinations. As a result, the control circuit 10 identifies the type of the medium adapter 20 from the combination of the pressed tape width detection switch 36, and detects the width (tape width) of the heat-sensitive tape 21 housed in the medium adapter 20.

In the printing apparatus 1 configured as described above, the platen roller 5 is provided so as to stop the transfer of the thermal tape 21 when the temperature of the thermal head 6 rises to the first temperature or higher during the printing process. The thermal head 6 is controlled so as to continue printing on the heat-sensitive tape 21 during the period from the start of the control to the actual stop of the transfer of the heat-sensitive tape 21 (the period during which the heat-sensitive tape 21 is coasted). The printing process is temporarily interrupted by a stop process such as controlling the printing process. After that, when the temperature of the thermal head 6 drops to less than the second temperature (<first temperature), the interrupted printing process is restarted. As a result, printing can be performed even during the period when the heat-sensitive tape 21 is inertially conveyed, so that a printing result without printing omission can be obtained. The reason why such inertial transfer of the heat-sensitive tape 21 occurs is that when the transfer of the heat-sensitive tape 21 is performed by the DC motor which is the transfer motor 32, the transfer of the heat-sensitive tape 21 is controlled to be stopped. However, it is not possible to immediately stop the transport of the heat-sensitive tape 21. Such a print control process will be specifically described with reference to FIGS. 4 to 7.

FIG. 4 is a flowchart showing an example of print control processing, and also shows a printing method. FIG. 5 is a flowchart showing an example of the stop process. FIG. 6 is a diagram showing an example of an inertial transport amount table. FIG. 7 is a diagram showing an example of printing results by this method and the conventional method. The processes shown in FIGS. 4 and 5 are processes performed by the control circuit 10 when the processor executes the program stored in the ROM 12. The print control process shown in FIG. 4 starts, for example, when the printing apparatus 1 acquires a print instruction from the computer 100 together with print data such as a print pattern.

When the print control process shown in FIG. 4 is started, the control circuit 10 first starts the print process (step S11). Here, the control circuit 10 controls the platen roller and the thermal head 6 based on the print data, and starts a process of printing the print pattern on the thermal tape 21 line by line.

Next, the control circuit 10 acquires the temperature of the thermal head 6 (step S12). Here, the control circuit 10 acquires the temperature of the thermal head 6 detected by the thermistor 15.

Next, the control circuit 10 determines whether or not the temperature of the thermal head 6 acquired in step S12 is lower than the first temperature (step S13). Here, the first temperature is a temperature determined based on the upper limit of the guaranteed operating temperature of the thermal head 6, and the temperature of the thermal head 6 also rises due to the temperature rise due to printing during the stop processing of step S15 described later. The temperature should not exceed the upper limit of the guaranteed operating temperature. For example, if it is assumed that the upper limit of the guaranteed operating temperature of the thermal head 6 is 65 ° C. and the maximum temperature rise due to printing during the stop processing is 2 ° C., the first temperature is 63 ° C. (65 ° C.). ℃ -2 ℃). As a result, the temperature of the thermal head 6 can be prevented from exceeding the upper limit of the guaranteed operating temperature.

If the determination result in step S13 is YES, then the control circuit 10 determines whether or not the printing process is completed (step S14). Here, the control circuit 10 determines whether or not the printing process started in step S11 has been performed to the end.

If the determination result in step S14 is YES, the print control process ends. In this case, although not shown, the heat-sensitive tape 21 is cut by the full cutter 7 or the half cutter 8. On the other hand, if the determination result in step S14 is NO, the process returns to S12 and the printing process is continued.

On the other hand, when the determination result in step S13 is NO (that is, when the temperature of the thermal head is equal to or higher than the first temperature), the control circuit 10 then performs a stop process (step S15). In the stop process of step S15, as shown in FIG. 5, the control circuit 10 first determines the inertial transport amount (step S21). The inertial transfer amount is the inertial transfer of the heat-sensitive tape 21 assumed during the stop process (more specifically, the period from the start of the transfer stop control in step S22 described later to the actual stop of the transfer of the heat-sensitive tape 21). The quantity. Here, the control circuit 10 derives the inertial transfer amount with reference to the inertial transfer amount table stored in the ROM 12. As shown in FIG. 6, the inertial transfer amount table stores the inertial transfer amount corresponding to the tape width of the heat-sensitive tape 21, and the control circuit 10 derives the inertial transfer amount according to the corresponding tape width. .. For example, when the tape width of the heat-sensitive tape 21 housed in the printing apparatus 1 is 6 mm, 6 lines are derived as the inertial transport amount. Thereby, the inertial transport amount can be determined in consideration of the tape width of the heat-sensitive tape 21.

Next, the control circuit 10 performs transport stop control (step S22). Here, the control circuit 10 controls the platen roller 5 so as to stop the transfer of the thermal tape 21. In this case, a control signal for stopping the DC motor is input to the DC motor which is the transport motor 32.

Next, the control circuit 10 prints the amount of inertial transport determined in step S21 (step S23). Here, the control circuit 10 controls the thermal head 6 so as to perform printing corresponding to the amount of inertial transport thereof. The energization time to the heat generating element 6a at this time is based on the transport speed of the heat-sensitive tape 21 before starting the transport stop control in step S22, or based on the assumed inertial transport speed of the heat-sensitive tape 21. , May be decided. When printing for the amount of inertial transport in step S23 is completed, the stop process is completed.

When the stop process of step S15 in FIG. 4 is completed in this way, the control circuit 10 then acquires the temperature of the thermal head 6 in the same manner as in step S12 (step S16).

Next, the control circuit 10 determines whether or not the temperature of the thermal head 6 acquired in step S16 is lower than the second temperature (step S17). Here, the second temperature is a temperature lower than the first temperature and is a temperature at which the printing process can be restarted. For example, the second temperature is 60 ° C. when the first temperature is 63 ° C.

If the determination result in step S17 is NO, the process returns to step S16. After the stop process of step S15 is completed, the print process is interrupted while the determination result of step S13 repeats NO.

On the other hand, if the determination result in S17 is YES, the control circuit 10 restarts the interrupted printing process (step S18), and the process returns to step S14. In the restart of the printing process in step S18, the control circuit 10 controls the platen roller 5 so as to restart the transfer of the heat-sensitive tape 21, and controls the thermal head 6 so as to restart printing on the heat-sensitive tape 21. do.

According to the print control process described above, the stop process is temporarily interrupted due to the temperature rise of the thermal head 6 during the print process, and then the print process is restarted due to the temperature drop of the thermal head 6. In this case, since printing is performed even while the heat-sensitive tape 21 is coasted during the stop processing, it is possible to obtain a printing result without printing omission. The printing result at this time will be described in comparison with the conventional method by giving a specific example. As shown in FIG. 7, in the conventional method, printing and transfer of the thermal tape 21a are stopped immediately when the stop processing is started. Since the control for printing is performed, printing is not performed during the coastal transfer of the thermal tape 21a, and as a result, there is a gap between the stop processing start position and the printing processing restart position where printing is not performed, and there is printing omission. The print result has been obtained. On the other hand, in this method (method by the print control process of FIG. 4), printing is performed even during the coastal transfer of the heat-sensitive tape 21 during the stop process (that is, the inertial transfer of the heat-sensitive tape 21 is taken into consideration. Since the printing control is performed), printing can be performed between the stop processing start position and the printing processing restart position, and a printing result without printing omission can be obtained.

<Modification example>
In the above-described embodiment, the stop process shown in FIG. 5 is performed as the stop process of step S15 in FIG. 4, but the stop process shown in FIG. 8 may be performed. FIG. 8 is a flowchart showing a modified example of the stop processing. The stop process shown in FIG. 8 is obtained by adding a process (step S31 to step S33) such as reducing the transport speed of the heat-sensitive tape 21 before the process from step S21 to step S23 in the stop process shown in FIG. Is. As a result, the amount of inertial transport of the heat-sensitive tape 21 during the stop processing can be reduced, and the variation in the amount of inertial transport thereof can also be reduced.

Specifically, in the stop process shown in FIG. 8, the control circuit 10 first performs the transfer speed reduction control (step S31). Here, the control circuit 10 controls the platen roller 5 so as to reduce the transfer speed of the heat-sensitive tape 21 stepwise or continuously. For example, the platen roller 5 is controlled so as to gradually or continuously reduce the transport speed from 20 mm / s to 10 mm / s.

Next, the control circuit 10 measures the transport speed (step S32). Here, the control circuit 10 measures the transport speed of the thermal tape 21 based on the signal from the encoder 33.

Next, the control circuit 10 determines the energization time (step S33). Here, the control circuit 10 determines the energization time to the heat generating element 6a in the printing performed in the later step S23 based on the transfer speed measured in the step S32. This makes it possible to prevent deterioration of the print quality in the printing performed in the subsequent step S23.

Then, the control circuit 10 starts the transfer speed reduction control in step S31, transfers a predetermined transfer amount of the heat-sensitive tape 21 (for example, a transfer amount for 32 lines), and then transfers the heat-sensitive tape 21 from step S21 to step S23. Processing is performed, and the stop processing shown in FIG. 8 is completed. However, the energizing time in printing performed in step S23 of FIG. 8 is the energizing time determined in step S33 as described above. In printing during the transfer of the predetermined transfer amount of the heat-sensitive tape 21 after the transfer speed reduction control in step S31 is started, the energization time to the heat generating element 6a may be longer than that before the start of the stop process.

Further, in the above-described embodiment, in step S21 of FIG. 5 (the same applies to step S21 of FIG. 8), the control circuit 10 determines the inertial transfer amount according to the tape width of the heat-sensitive tape 21, but the heat-sensitive tape 21 The inertial transport amount may be determined according to the tape width and the transport speed. In this case, the inertial transfer amount table storing the inertial transfer amount according to the combination of the tape width and the transfer speed of the heat-sensitive tape 21 is stored in the ROM 12, and the control circuit 10 inertially refers to the inertial transfer amount table. The transport amount may be derived. FIG. 9 is a diagram showing an example of such an inertial transport amount table. For example, when the tape width of the heat-sensitive tape 21 housed in the printing apparatus 1 is 6 mm and the transport speed at that time is the transport speed A, 6 lines are derived as the inertial transport amount. In this way, the inertial transport amount can be determined in consideration of the tape width and the transport speed of the heat-sensitive tape 21. Further, in the above-described embodiment, in printing for the inertial transport amount in step S23 of FIG. 5 (the same applies to step S23 in FIG. 8), the inertial transport amount determination process in step S21 is performed with the inertial transport amount as a fixed value. You may omit it. The inertial transfer amount stored in the inertial transfer amount table described above and the inertial transfer amount as the fixed value described above are learned based on the actual inertial transfer amount of the heat-sensitive tape 21 measured based on the signal from the encoder 33. It may be updated each time to the inertial transport amount.

Further, in the above-described embodiment, the first temperature used for the determination in step S13 of FIG. 4 is determined based on the upper limit of the guaranteed operation temperature of the thermal head 6 as described above, and the step. Even if printing is performed during the stop processing of S15, the temperature of the thermal head 6 is set to such a temperature that the upper limit of the guaranteed operation temperature is not exceeded. Such a first temperature determination may be made, for example, by the control circuit 10 with reference to the rising temperature table. FIG. 10 is a diagram showing an example of an ascending temperature table. As shown in FIG. 10, the ascending temperature table stores the expected maximum ascending temperature of the thermal head 6 according to the print data (for example, the amount of print data) expected to be printed during the stop processing. Has been done. The control circuit 10 may refer to such an ascending temperature table and derive a value obtained by subtracting the corresponding ascending temperature from the upper limit of the guaranteed operating temperature of the thermal head 6 as the first temperature. As a result, the first temperature can be set to a temperature corresponding to the print data expected to be printed during the stop processing. Alternatively, the ascending temperature table may store the expected maximum ascending temperature of the thermal head 6 according to the assumed transport speed of the thermal tape 21 during the stopping process, or is printed during the stopping process. The maximum expected temperature rise of the thermal head 6 may be stored according to the combination of the print data expected to be printed and the expected transfer speed of the thermal tape 21 during the stop processing. It should be noted that such an elevated temperature table is stored in, for example, the ROM 12.

The printing apparatus, printing method, and program can be variously modified and modified without departing from the description of the claims.
