<Operation>
A printing operation of the printing apparatus 100 will be described. The image data transferred to the printing apparatus 100 is converted into print data for printing by the transfer control unit 21. At the time of transferring each color dye, the thermal head 2 is pressed against the platen roller 6 and applies a heat amount corresponding to the print data to the ink sheet 9 and the printing paper 8. The dye of the heated ink sheet 9 is sublimated and transferred to the printing paper 8. Y, M, C, and OP transfer operations are repeated on one screen of the printing paper 8 to form a printed matter. At this time, the printing paper 8 is pressure-bonded between the grip roller 7a and the pinch roller 7b under the control of the printing paper conveyance control unit 23, and is conveyed using a stepping motor (not shown) as a drive source. The ink sheet 9 is taken up with a predetermined tension by an ink take-up motor (not shown) driven by the ink sheet conveyance control unit 22 via the ink take-up reel 10a. The ink supply reel 10b is also directly connected to a torque limiter (not shown) so that the ink sheet 9 has a predetermined tension.

  FIG. 5 is a diagram illustrating a cutting operation of the cutter 11 of the printing apparatus 100. FIG. 6 is a flowchart showing the operation of the printing apparatus 100.

  As shown in FIG. 5, the transfer operation of each color of Y, M, C, and OP is completed on the printing paper 8, and the printing portion 8a is formed (step ST1 in FIG. 6). Next, the printing paper conveyance control unit 23 controls the printing paper conveyance mechanism 7 c to convey the printing paper 8 on which the printing unit 8 a is formed until the broken line position A of the printing paper 8 reaches the cutting position of the cutter 11. (Step ST2 in FIG. 6). The printing paper 8 is transported by driving a predetermined pulse by a stepping motor (not shown).

  Next, as a result of the conveyance in step ST2, it is determined whether or not the leading edge of the printing paper 8 is on the discharge port 12 side from the cutting position of the cutter 11 by the length of the cutting waste 14 (ie, a predetermined cutting width). (Step ST3 in FIG. 6). Here, it is assumed that the cutting width of the cutting waste 14 is stored in advance in the printing paper transport control unit 23, for example. When the leading edge of the printing paper 8 is conveyed from the cutting position of the cutter 11 toward the discharge port 12 by the length of the cutting waste 14, the cutter control unit 25 controls the cutter 11 to cut the printing paper 8. (Step ST4 in FIG. 6). That is, the cutter 11 cuts the printing paper 8 at the broken line position A in FIG. By cutting, cutting waste 14 having a predetermined cutting width is generated. The cutting waste 14 includes a print blank portion 8b that is not transferred and a part of the end of the print portion 8a. The reason for cutting so as to include a part of the print portion 8a is to obtain a print product without borders. The cutting waste 14 falls and is stored in the cutting waste storage box 15.

  When cutting is performed in step ST4, the accumulation amount detection unit 26 counts the number of pieces 14 (step ST5 in FIG. 6). That is, the accumulation amount detection unit 26 adds 1 to the total number of cutting scraps 14 counted so far.

  Further, the printing paper conveyance control unit 23 controls the printing paper conveyance mechanism 7c to convey the printing paper 8 until the broken line position B of the printing paper 8 reaches the cutting position of the cutter 11 (step ST6 in FIG. 6). Then, the cutter control unit 25 controls the cutter 11 to cut the printing paper 8 (step ST7 in FIG. 6). That is, the cutter 11 cuts the printing paper 8 at the broken line position B in FIG. By this cutting, the printing paper 8 is separated from the printing paper roll 81 and is discharged from the discharge port 12 as a printed matter.

  The accumulation amount determination unit 27 stores a threshold value in advance. Here, the threshold is the amount of cutting waste 14 that can be stored in the cutting waste storage box 15. The threshold value is set as, for example, the total length of the cutting scraps 14. For example, when the threshold is 100 cm and the cutting width of the cutting waste 14 is 1 cm, 100 pieces of cutting waste 14 can be stored in the cutting waste storage box 15.

  The accumulation amount detection unit 26 detects the amount of cutting waste 14 accumulated in the cutting waste storage box 15 based on the counted number of cutting wastes 14 and the cutting width of the cutting waste 14. For example, the accumulation amount detection unit 26 calculates the amount of the cutting waste 14 accumulated in the cutting waste storage box 15 by multiplying the number of the cutting wastes 14 by the cutting width of the cutting waste 14.

  The accumulation amount determination unit 27 determines whether or not the amount of cutting waste 14 accumulated in the cutting waste storage box 15 has reached a predetermined threshold (step ST8 in FIG. 6).

  When it is determined in step ST8 that the accumulated amount of the cutting waste 14 exceeds the threshold value, the notification unit 30 outputs an audio to prompt the user to discard the cutting waste 14 accumulated in the cutting waste storage box 15. Alternatively, an image or a character is displayed (ST9 in FIG. 6). For example, the notification unit 30 outputs a warning sound from a speaker. Further, the notification unit 30 may cause the LED to blink, display a character prompting disposal on the display, or the like. Here, the display may be a screen of a PC (Personal Computer) connected to the printing apparatus 100.

  When the user removes the cutting waste storage box 15 from the printing apparatus 100 in order to discard the cutting waste 14 accumulated in the cutting waste storage box 15, the cutting waste storage box detection sensor 40 detects the removal of the cutting waste storage box 15. . When the cutting waste storage box detection sensor 40 detects the removal of the cutting waste storage box 15, the accumulation amount detection unit 26 resets the counted number of cutting wastes 14 to zero.

  The cutting waste 14 may be generated even after the OP transfer. When the OP is not transferred to the printed matter, the print amount 8 is transported by a predetermined pulse up to the cutter 11 after the C transfer, and even when the cutting is performed, the accumulated amount detection unit 26 removes the cutting waste 14. Count.

  Further, when the printing is completed without being completed, the printing apparatus 100 discards the printing portion in the cutting waste storage box 15 without discharging the printing portion from the discharge port 12. In this case, the operation of conveying and cutting the printing paper 8 with a predetermined pulse corresponding to the cutting width of the cutting waste 14 from the sensor (not shown) that detects the leading edge of the printing paper 8 to the cutter 11 is repeated. Also in this case, the accumulation amount detection unit 26 counts the cutting waste 14.

<Effect>
The printing apparatus 100 according to the first embodiment includes a printing unit 10 that prints on the printing paper 8, a cutter 11 that cuts the printing paper 8 in the paper width direction, and a cut that is cut off from the printing paper 8 by cutting with the cutter 11. A cutting waste storage box 15 that stores the waste 14, a deposition amount detection unit 26 that detects the amount of the cutting waste 14 accumulated in the cutting waste storage box 15 based on the operation of the cutter 11, and a detection result of the deposition amount detection unit 26.

  Therefore, the printing apparatus 100 according to the first embodiment detects the amount of cutting waste 14 accumulated in the cutting waste storage box 15 based on the operation of the cutter 11. Therefore, there is no need to provide additional parts such as a rotating blade for detecting the amount of cutting waste 14, a motor for driving the rotating blade, and a transmission gear, as in the prior art. Therefore, it is possible to obtain the printing apparatus 100 that detects the accumulation amount of the cutting waste 14 with a simpler configuration. In addition, the size of the printing apparatus 100 can be reduced and the manufacturing cost can be reduced by reducing the number of parts.

  According to the printing apparatus 100 of the first embodiment, when the accumulated amount of the cutting waste 14 reaches a predetermined threshold value, the notification unit 30 outputs sound or displays images or characters. Thereby, it is possible to urge the user to discard the cutting waste 14 and to prevent the cutting waste 14 from overflowing from the cutting waste storage box 15 and causing a paper jam (jam).

  In the printing apparatus 100 according to the first embodiment, the cutting width per piece of cutting waste 14 is determined in advance, and the accumulation amount detection unit 26 counts the number of cutting pieces 14 cut by the cutter 11, Based on the cutting width per piece of cutting waste 14 and the counted number, the amount of cutting waste 14 accumulated in the cutting waste storage box 15 is calculated.

  Therefore, the accumulation amount detection unit 26 counts the number of cutting pieces 14 cut by the cutter 11, so that the number of cutting pieces 14 and the cutting width per piece of cutting pieces 14 are counted in the cutting piece storage box 15. It is possible to calculate the amount of accumulated cutting waste 14.

  The printing apparatus 100 according to the first embodiment further includes a cutting waste storage box detection sensor 40 that detects the removal of the cutting waste storage box 15, and the accumulation amount detection unit 26 stores the cutting waste storage box detection sensor 40. When the removal of the box 15 is detected, the count of the number of pieces 14 is reset.

  Therefore, when the user removes the cutting waste storage box 15 from the printing apparatus 100 in order to discard the cutting waste 14 accumulated in the cutting waste storage box 15, the count of the number of cutting wastes 14 is reset. This saves the user from having to reset the count, improving convenience.

<Embodiment 2>
FIG. 7 is a schematic cross-sectional view of the printing apparatus 200 according to the second embodiment. The printing apparatus 200 according to the second embodiment further includes a removal restricting mechanism 41 with respect to the printing apparatus 100. The removal restricting mechanism 41 restricts the removal of the cutting waste storage box 15 when the printing apparatus 200 is powered off. Since other configurations are the same as those of the printing apparatus 100, description thereof is omitted.

  The removal restricting mechanism 41 includes a shaft 41a and a lever 41b fixed to the shaft 41a. The shaft 41a is rotated by a motor (not shown). When the shaft 41a rotates, the state where the lever 41b is hooked on the cutting waste storage box 15 (FIG. 7) and the state where the hook is released are switched. When the power of the printing apparatus 200 is turned off, the shaft 41a rotates and the lever 41b is caught by the cutting waste storage box 15.

  Note that a restriction release button 42 may be further provided in the printing apparatus 200. When the restriction release button 42 is pressed, the shaft 41a is rotated, and the hook of the lever 41b on the cutting waste storage box 15 is released. Preventing the user from accidentally removing the cutting waste storage box 15 by pressing the restriction release button 42 before the user removes the cutting waste storage box 15 while the power of the printing apparatus 200 is on. Is possible.

<Effect>
The printing apparatus 200 according to the second embodiment further includes a removal restriction mechanism 41 that regulates removal of the cutting waste storage box 15 when the power of the printing apparatus 200 is off.

  By restricting the removal of the cutting waste storage box 15 while the power of the printing apparatus 200 is turned off, the cutting waste storage box 15 is removed while the power is off to prevent the cutting waste 14 from being discarded. Is possible. Thereby, it is possible to prevent the count number of the accumulation amount detection unit 26 from being different from the number of the cutting waste 14 actually deposited in the cutting waste storage box 15.

<Embodiment 3>
FIG. 8 is a block diagram of the printing apparatus 300 according to the third embodiment. The printing apparatus 300 according to the third embodiment further includes a temperature sensor 31 and a humidity sensor 32 with respect to the printing apparatus 100. The temperature sensor 31 measures the temperature in the installation environment of the printing apparatus 300. The humidity sensor 32 measures the humidity in the installation environment of the printing apparatus 300. Since the other configuration is the same as that of the printing apparatus 300, description thereof is omitted.

  The control unit 20 (that is, the accumulation amount determination unit 27) changes the threshold based on the measurement results of the humidity sensor 32 and the temperature sensor 31. As described in the first embodiment, the threshold value is the amount of cutting waste 14 that can be stored in the cutting waste storage box 15. If the cutting waste 14 is left unattended depending on the ambient humidity and temperature environment, the curl (warpage) changes. In particular, strips such as cutting waste 14 are easily affected by humidity and temperature environment. For example, curl is likely to occur on the cutting waste 14 in a winter environment where the humidity is low. When curl is generated in the cutting waste 14, the cutting waste 14 is bulky, and the amount of cutting waste 14 that can be stored in the cutting waste storage box 15 is reduced.

  Therefore, for example, when the humidity is lower than a predetermined value for 24 hours, or when the temperature is lower than a predetermined value for 24 hours, the deposition amount determination unit 27 sets the threshold to a smaller threshold. change. The threshold changing condition based on humidity and temperature is not limited to this. Further, when the cutting waste storage box detection sensor 40 detects the removal of the cutting waste storage box 15, the threshold value may be returned to the initial set value.

  Further, in the third embodiment, the control unit 20 (that is, the accumulation amount determination unit 27) changes the cutting width per piece of cutting waste based on the measurement results of the humidity sensor 32 and the temperature sensor 31. Good.

  As described above, when curl is generated in the cutting waste 14, the cutting waste 14 is bulky, so that the amount of cutting waste 14 that can be stored in the cutting waste storage box 15 is reduced. Therefore, when curling is expected to occur in the cutting waste 14, the cutting width per cutting waste is reduced. Thereby, the bulk of the cutting waste 14 in the cutting waste storage box 15 can be suppressed. Specifically, for example, when the humidity is lower than a predetermined value for 24 hours, or when the temperature is lower than a predetermined value for 24 hours, the accumulation amount determination unit 27 determines the amount of cutting waste. The cutting width per piece is changed to half of the initial value. In addition, the change conditions of the cutting width based on humidity and temperature are not limited to this. Further, when the cutting waste storage box detection sensor 40 detects the removal of the cutting waste storage box 15, the cutting width may be returned to the initial set value.

<Effect>
The printing apparatus 300 according to the third embodiment further includes a humidity sensor 32 that measures humidity in the installation environment of the printing apparatus 300 or a temperature sensor 31 that measures temperature in the installation environment of the printing apparatus 300, and includes a control unit 20 ( That is, the accumulation amount determination unit 27) changes the threshold value based on the measurement result of the humidity sensor 32 or the temperature sensor 31.

  Therefore, when it is predicted that curl will occur in the cutting waste 14, the threshold value (that is, the amount of cutting waste 14 that can be stored in the cutting waste storage box 15) based on the measurement result of the humidity sensor 32 or the temperature sensor 31. By changing to a smaller threshold, paper jam can be suppressed even in an environment where the humidity and temperature change.

  The printing apparatus 300 according to the third embodiment further includes a humidity sensor 32 that measures humidity in the installation environment of the printing apparatus 300 or a temperature sensor 31 that measures temperature in the installation environment of the printing apparatus 300, and includes a control unit. 20 (that is, the accumulation amount determination unit 27) changes the cutting width per piece of the cutting waste 14 based on the measurement result of the humidity sensor 32 or the temperature sensor 31.

  Therefore, when it is predicted that curl will occur in the cutting waste 14, the humidity and temperature are changed by changing the cutting width of the cutting waste 14 to a smaller width based on the measurement result of the humidity sensor 32 or the temperature sensor 31. It is possible to suppress paper jams even in an environment where the temperature changes.
