<Operation>
The printing operation of the printing apparatus 100 will be described. The image data transferred to the printing apparatus 100 is converted by the transfer control unit 21 into print data for printing. At the time of transfer of 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 on the heated ink sheet 9 is sublimated and transferred to the printing paper 8. The transfer operation of Y, M, C, and OP is repeated for one screen of the printing paper 8 to form a print. At this time, the printing paper 8 is pressed between the grip roller 7a and the pinch roller 7b under the control of the printing paper transport control unit 23, and is transported using a stepping motor (not shown) as a drive source. The ink sheet 9 is wound by a predetermined tension by driving an ink winding motor (not shown) by the ink sheet transport control unit 22 via the ink winding reel 10a. The ink unwinding 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 the cutting operation of the cutter 11 of the printing apparatus 100. FIG. 6 is a flowchart illustrating the operation of the printing apparatus 100.

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

  Next, as a result of the conveyance in step ST2, it is determined whether or not the leading end of the printing paper 8 is closer to the outlet 12 by the length of the cutting waste 14 (ie, a predetermined cutting width) from the cutting position of the cutter 11. (Step ST3 in FIG. 6). Here, it is assumed that the cutting width of the cutting waste 14 is stored in advance in, for example, the printing paper transport control unit 23. When the leading end of the printing paper 8 is conveyed from the cutting position of the cutter 11 to 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. The cutting generates cutting chips 14 having a predetermined cutting width. The cutting waste 14 includes a print margin portion 8b to which no transfer is performed and a part of an end of the print portion 8a. The cutting is performed so as to include a part of the printing portion 8a in order to obtain a printed material without a border. The cutting waste 14 falls and is stored in the cutting waste storage box 15.

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

  Further, the print paper transport control unit 23 controls the print paper transport mechanism 7c to transport the print paper 8 until the broken line position B of the print paper 8 reaches the cutting position of the cutter 11 (step ST6 in FIG. 6). Then, the cutter controller 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 discharged from the discharge port 12 as a print.

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

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

  The accumulation amount determination unit 27 determines whether the amount of the cutting waste 14 accumulated in the cutting waste storage box 15 has reached a predetermined threshold (step ST8 in FIG. 6).

  If it is determined in step ST8 that the accumulation amount of the cutting waste 14 exceeds the threshold value, the notification unit 30 outputs a sound to urge 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. In addition, the notification unit 30 may cause the LED to blink, display a character urging 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 the cutting wastes 14 to zero.

  The cutting waste 14 may be generated even after the OP transfer. If the OP is not transferred to the print, the printing paper 8 is conveyed at a predetermined pulse up to the cutter 11 after the C transfer, and even when cutting is performed, the accumulation amount detection unit 26 removes the cutting waste 14. Count.

  If the printing is not completed and the printing is completed halfway, the printing apparatus 100 discards the printed portion in the cutting waste storage box 15 without discharging the printed portion from the discharge port 12. In this case, the operation of transporting and cutting the printing paper 8 from the sensor (not shown) that detects the leading end of the printing paper 8 to the cutter 11 with a predetermined pulse corresponding to the cutting width of the cutting waste 14 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 cutting that is separated from the printing paper 8 by the cutting performed by the cutter 11.

  Therefore, the printing apparatus 100 according to the first embodiment detects the amount of the cutting chips 14 accumulated in the cutting chip storage box 15 based on the operation of the cutter 11. Therefore, it is not necessary to provide additional components such as a rotary wing for detecting the amount of cutting waste 14, a motor for driving the rotary wing, and a transmission gear as in the conventional case. 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 reduction in the number of parts can reduce the size of the printing apparatus 100 and the manufacturing cost.

  According to the printing apparatus 100 of the first embodiment, when the accumulation amount of the cutting wastes 14 reaches the predetermined threshold, the notification unit 30 outputs sound or displays images or characters. Thereby, it is possible to prompt the user to discard the cutting waste 14 and to suppress 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 the cutting waste 14 is predetermined, and the accumulation amount detection unit 26 counts the number of the cutting waste 14 cut by the cutter 11, The amount of the cutting chips 14 accumulated in the cutting chip storage box 15 is calculated based on the cutting width per piece of the cutting chips 14 and the counted number.

  Therefore, the accumulation amount detection unit 26 counts the number of the cutting chips 14 cut by the cutter 11, and based on the counted number and the cutting width per one of the cutting chips 14, the number of the cutting chips 14 is stored in the cutting chip storage box 15. It is possible to calculate the amount of the accumulated cutting waste 14.

  The printing apparatus 100 according to the first embodiment further includes a cutting chip storage box detection sensor 40 that detects removal of the cutting chip storage box 15. When the removal of the box 15 is detected, the count of the number of the cutting wastes 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 the cutting waste 14 is reset. This saves the user from having to reset the count, thereby improving convenience.

<Embodiment 2>
FIG. 7 is a schematic sectional view of a printing apparatus 200 according to the second embodiment. The printing apparatus 200 according to the second embodiment further includes a removal restriction mechanism 41 with respect to the printing apparatus 100. The removal control mechanism 41 controls removal of the cutting waste storage box 15 when the power of the printing apparatus 200 is off. The other configuration is the same as that of the printing apparatus 100, and the description 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). The rotation of the shaft 41a switches between a state in which the lever 41b is hooked on the cutting waste storage box 15 (FIG. 7) and a state in which the hook is released. When the power of the printing apparatus 200 is turned off, the shaft 41 a rotates and the lever 41 b is in a state of being caught by the cutting waste storage box 15.

  Note that a restriction release button 42 may be further provided on the printing apparatus 200. When the restriction release button 42 is pressed, the shaft 41a is rotated, and the lever 41b is released from being caught on 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 turned on, it is possible to prevent the user from accidentally removing the cutting waste storage box 15. Is possible.

<Effect>
The printing apparatus 200 according to the second embodiment further includes a removal control mechanism 41 that controls 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 when the power of the printing apparatus 200 is off, it is possible to prevent the cutting waste storage box 15 from being removed and the cutting waste 14 being discarded while the power is off. 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 chips 14 actually stacked in the cutting chip storage box 15.

<Embodiment 3>
FIG. 8 is a block diagram of a 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 a temperature in an environment where the printing apparatus 300 is installed. The humidity sensor 32 measures the humidity in the environment where the printing apparatus 300 is installed. The other configuration is the same as that of the printing apparatus 300, and the description 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 is the amount of the cutting waste 14 that can be stored in the cutting waste storage box 15. The curd (warpage) of the cutting waste 14 changes depending on the surrounding humidity and temperature environment. In particular, a strip-shaped material such as cutting waste 14 is easily affected by humidity and temperature environment. For example, curl is likely to occur in the cutting waste 14 in a low humidity environment in winter. When the cutting chips 14 are curled, the amount of cutting chips 14 that can be stored in the cutting chip storage box 15 decreases because the cutting chips 14 are bulky.

  Therefore, for example, when the humidity is lower than the predetermined value for 24 hours continuously, or when the temperature is lower than the predetermined value for 24 hours, the deposition amount determination unit 27 sets the threshold to a smaller threshold. change. Note that the threshold changing condition based on the humidity and the 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 chips based on the measurement results of the humidity sensor 32 and the temperature sensor 31. Good.

  As described above, when curling occurs in the cutting chips 14, the cutting chips 14 become bulky, and thus the amount of cutting chips 14 that can be stored in the cutting chip storage box 15 decreases. Therefore, if curling is expected to occur in the cutting chips 14, the cutting width per piece of cutting chips is reduced. This makes it possible to suppress the bulk of the cutting waste 14 in the cutting waste storage box 15. Specifically, for example, when the humidity is lower than a predetermined value for 24 hours continuously, or when the temperature is lower than a predetermined value for 24 hours continuously, the accumulation amount determination unit 27 sets Change the cutting width per piece to half of the initial value. The conditions for changing the cutting width based on the humidity and the temperature are not limited to these. 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 an environment where the printing apparatus 300 is installed, or a temperature sensor 31 that measures temperature in an environment where the printing apparatus 300 is installed. That is, the accumulation amount determination unit 27) changes the threshold based on the measurement result of the humidity sensor 32 or the temperature sensor 31.

  Therefore, when curling is predicted to occur in the cutting waste 14, a threshold value (that is, the amount of the cutting waste 14 that can be stored in the cutting waste storage box 15) is determined 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 humidity and temperature change.

  The printing apparatus 300 according to the third embodiment further includes a humidity sensor 32 that measures humidity in an environment where the printing apparatus 300 is installed, or a temperature sensor 31 that measures temperature in an environment where the printing apparatus 300 is installed. 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 curling is predicted to occur in the cutting waste 14, 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, the humidity and the temperature are reduced. It is possible to suppress paper jam even in an environment where fluctuates.
