Similarly, the third transport unit 143 includes a third stepping motor 143M and a third transport roller 143R that is rotationally driven by the third stepping motor 143M.

  Note that at least the first stepping motor 141M and the second stepping motor 142M rotate forward (forward rotation) in accordance with a forward rotation instruction from the control unit 10. In response to this, the first transport roller 141R and the second transport roller 142R rotate forward (forward rotation). Then, the sheet S is pulled out from the sheet roll accommodated in the sheet supply unit 17, and the sheet S is conveyed (forward direction conveyance) toward the discharge port 191 of the discharge unit 19. In addition, at least the second stepping motor 142M and the third stepping motor 143M rotate in reverse according to the reverse rotation instruction from the control unit 10. In response to this, the second conveyance roller 142R and the third conveyance roller 143R rotate in reverse. Then, the cut sheet CS is drawn and conveyed (reverse direction conveyance) from the discharge port 191.

  Further, as shown in FIG. 2, the first flapper 145 rotates to the first position (home position) and stops in accordance with a positioning instruction to the first position from the control unit 10.

  The recording unit 15 prints the predetermined information on the sheet S by heat or ink based on an instruction to record the predetermined information from the control unit 10. The cutter 16 cuts the sheet S conveyed between the first conveyance unit 141 and the second conveyance unit 142 at the timing of the cut instruction of the control unit 10.

  For example, the sheet supply unit 17 holds the sheet roll and supplies the sheet S. That is, the sheet S drawn from the sheet roll is supplied by the forward conveyance of the first conveyance unit 141 and the second conveyance unit 142.

  The sheet storage unit 18 includes a looping space 181 (first space) and a capture space 182 (second space). Hereinafter, the normal transfer mode, the looping transfer mode using the looping space 181 and the capture transfer mode using the capture space 182 will be described.

(Normal transport mode)
FIG. 6 is a flowchart illustrating an example of a normal transport mode of the printer according to the embodiment.

  The control unit 10 controls the cut length (cut timing) of the sheet S in accordance with the amount of information to be printed, but selects the normal conveyance mode when discharging the sheet CS cut to the first length or less ( ACT11). For example, when the control unit 10 prints the first information (when the cut length of the sheet S is controlled to be equal to or less than the first length), the normal conveyance mode is selected.

  The control unit 10 that has selected the normal conveyance mode outputs a positioning instruction to the first position to the first flapper 145 and outputs a positioning instruction to the fourth position to the second flapper 146. As a result, the first flapper 145 and the second flapper 146 are set to the home position (ACT 12). That is, as shown in FIG. 2, the first flapper 145 rotates to the first position (home position) and stops according to the positioning instruction from the control unit 10 to the first position. Further, the second flapper 146 rotates and stops at the fourth position (home position) in accordance with the positioning instruction to the second position from the control unit 10.

  Further, the control unit 10 (pulse oscillator of the control unit 10) outputs a pulse signal to the first stepping motor 141M and the second stepping motor 142M, and forward rotation, first speed, and first rotation angle (first rotation). (First rotation angle corresponding to one transport distance). The first stepping motor 141M and the second stepping motor 142M rotate forward by the first rotation angle at the first speed based on the pulse signal from the control unit 10. Correspondingly, the first transport unit 141 and the second transport unit 142 transport the sheet S in the forward direction at the first speed (normal speed) by the first transport distance (ACT 13).

In addition to the above conveyance control, the control unit 10 instructs the recording unit 15 to print the first information, and the recording unit 15 prints the first information on the conveyed sheet S (ACT 14). Further, the control unit 10 instructs cutting at the timing when the sheet S is conveyed by the first conveying distance, and the cutter 16 cuts the sheet S based on the cutting instruction (ACT 15). Thereby, the sheet | seat S is cut below to 1st length. The cut sheet is discharged from the discharge port 191 (ACT 16).
The first length is shorter than the length from the cutting position of the sheet S by the cutter 16 to the discharge port 191. As a result, the leading edge of the cut sheet CS reaches the discharge port 191. When the leading edge of the sheet is pulled by the user, printing by the recording unit 15 has already been completed and cutting by the cutter 16 has also been completed. For this reason, even if the front end of the sheet CS is pulled by the user, there is no problem in printing and cutting.

(Looping transfer mode)
FIG. 7 is a flowchart illustrating an example of a looping conveyance mode of the printer according to the embodiment.

  The control unit 10 controls the cut length (cut timing) of the sheet S according to the amount of information to be printed. The control unit 10 selects the looping conveyance mode when discharging the sheet CS cut to a second length (for example, the second length is twice the first length) longer than the first length. (ACT21). Alternatively, the looping conveyance mode is selected by the initial setting. For example, when the second information is printed (when the cut length of the sheet S is controlled to be equal to or longer than the second length), the control unit 10 selects the looping conveyance mode.

  The control unit 10 that has selected the looping conveyance mode first sets the first flapper 145 and the second flapper 146 to the home position until the leading edge of the sheet S reaches the second conveyance roller 142R of the second conveyance unit 142. . Then, the first transport unit 141 transports the sheet S. The leading edge of the sheet S reaches the second conveyance roller 142R of the second conveyance unit 142 by the control of the first stepping motor 141M. When this is detected, the control unit 10 that has selected the looping conveyance mode outputs a positioning instruction to the second position to the first flapper 145. Further, the control unit 10 outputs a positioning instruction to the fourth position to the second flapper 146. Furthermore, the control unit 10 sets the first flapper 145 to the looping conveyance position. Further, the control unit 10 sets the second flapper 146 to the home position (ACT 22). That is, as shown in FIG. 3, the first flapper 145 rotates to the second position (looping conveyance position) and stops according to the positioning instruction from the control unit 10 to the second position. Further, the second flapper 146 rotates to the fourth position (home position) and stops according to the positioning instruction from the control unit 10 to the fourth position. Accordingly, the first flapper 145 and the second flapper 146 provide (release) a discharge path through which the sheet S conveyed from the looping space 181 is conveyed, and distributes the sheet S toward the discharge port 191. Further, the second flapper 146 closes the collection path for collecting the sheet CS cut from the discharge port 191 toward the capture space 182.

  Further, the control unit 10 (pulse oscillator of the control unit 10) outputs a pulse signal to the first stepping motor 141M, and corresponds to the forward rotation, the first speed, and the second rotation angle (the second transport distance). (Second rotation angle). Further, the control unit 10 outputs a pulse signal to the second stepping motor 142M, forward rotation, a second speed lower than the first speed (for example, the second speed is 1/2 of the first speed), And the third rotation angle (a third rotation angle corresponding to the third transport distance (for example, the third rotation angle is 1/2 of the second rotation angle)). The first stepping motor 141M rotates forward by the second rotation angle at the first speed based on the pulse signal from the control unit 10. The second stepping motor 142M rotates forward by the third rotation angle at the second speed based on the pulse signal from the control unit 10. Correspondingly, the first transport unit 141 transports the sheet S in the forward direction at the first speed (normal speed) by the second transport distance. The second transport unit 142 transports the sheet S in the forward direction by the third transport distance at the second speed (low speed) (ACT 23).

  Further, the control unit 10 instructs the recording unit 15 to print the second information together with the conveyance control, and the recording unit 15 prints the second information on the conveyed sheet S (ACT 24).

  Execution of the looping conveyance mode causes a difference in conveyance speed between the first conveyance unit 141 and the second conveyance unit 142, and the sheet S between the first conveyance unit 141 and the second conveyance unit 142 is loosened. The looping space 181 accommodates the slack of the sheet S (slack of the loop-shaped sheet S) between the first transport unit 141 and the second transport unit 142 caused by the looping transport mode (ACT 25).

  According to the execution instruction of the looping conveyance mode from the control unit 10, the first conveyance unit 141 conveys the sheet S at the first speed in the forward direction, and the second conveyance unit 142 stops conveyance of the sheet S. It may be. Also in this case, the sheet S between the first conveyance unit 141 and the second conveyance unit 142 is loosened. In any case, the looping space 181 accommodates the slack of the looped sheet S that is pushed by the forward conveyance of the sheet S by the first conveyance unit 141. For example, the looping space 181 is provided below the conveyance path formed by the first conveyance unit 141 and the second conveyance unit 142 in order to accommodate the slack that falls due to the weight of the sheet S. If the accommodation space is provided above the conveyance path and the slack of the pushed up sheet S is accommodated, it is considered that the slack of the looped sheet S falls to the left and right and causes jamming. Since the looping space 181 of the present embodiment is provided below the conveyance path and accommodates the slack that falls due to the weight of the sheet S, jamming as described above can be reduced.

  Further, the control unit 10 instructs cutting at a timing when the sheet S is transported by the second transport distance by the first transport unit 141, and the cutter 16 cuts the sheet S based on the cutting instruction (ACT26). Thereby, the sheet | seat S is cut more than 2nd length.

  The second length is longer than the length from the cutting position of the sheet S by the cutter 16 to the discharge port 191. However, when the leading edge of the sheet CS to be cut reaches the discharge port 191 and the leading edge of the sheet CS is pulled by the user by the above looping, printing by the recording unit 15 has already been completed and cutting by the cutter 16 has been completed. Yes. Therefore, even if the leading end of the sheet CS is pulled by the user, there is no problem in printing and cutting.

(Discharge mode)
FIG. 8 is a flowchart illustrating an example of a discharge mode of the printer according to the embodiment.

  When printing and cutting are completed in the looping conveyance mode, the control unit 10 selects the discharge mode.

  The control unit 10 (pulse oscillator of the control unit 10) outputs a pulse signal to the second stepping motor 142M. Accordingly, the second stepping motor 142M is rotated forward, the first speed or the third speed higher than the first speed, and the fourth rotation angle (the fourth rotation angle corresponding to the fourth transport distance (for example, the fourth rotation angle is The difference between the second rotation angle and the third rotation angle)) is controlled. The second stepping motor 142M rotates forward by the fourth rotation angle at the first speed or the third speed based on the pulse signal from the control unit 10. In response to this, the second transport unit 142 transports the cut sheet CS in the forward direction by the fourth transport distance at the first speed (normal speed) or the third speed (high speed) (ACT 31).

  By executing the discharge mode, the second information is printed and the cut sheet CS is discharged from the discharge port 191 (ACT32). As a result, the leading edge of the sheet CS reaches the discharge port 191. When the leading edge of the sheet CS is pulled by the user, printing by the recording unit 15 has already been completed and cutting by the cutter 16 has also been completed. Therefore, even if the leading end of the sheet CS is pulled by the user, there is no problem in printing and cutting.

(Capture transfer mode)
FIG. 9 is a flowchart illustrating an example of the capture conveyance mode of the printer according to the embodiment.

  As described above, the sheet CS cut to the second length is discharged from the discharge port 191 by executing the discharge mode. The sheet detection sensor 192 provided in the discharge port 191 detects the discharged sheet CS (ACT 41), and the forgetting timer 193 starts a timer count based on the detection of the discharged sheet CS by the sheet detection sensor 192. (ACT42). When the forgetting timer 193 counts a predetermined time (for example, a time set between 20 seconds and 3 minutes) (ACT43), the control unit 10 selects the capture conveyance mode (ACT44).

  The control unit 10 that has selected the capture conveyance mode outputs a positioning instruction to the third position to the first flapper 145 and outputs a positioning instruction to the fifth position to the second flapper 146. As a result, the first flapper 145 and the second flapper 146 are set to the capture position (ACT 45). That is, as shown in FIG. 4, the first flapper 145 rotates to the third position (capture position) and stops according to the positioning instruction from the control unit 10 to the third position. Further, the second flapper 146 rotates and stops at the fifth position (capture position) according to the positioning instruction from the control unit 10 to the fifth position. As a result, the first flapper 145 closes the backflow path from the discharge port 191 to the first transport unit 141. In addition, the second flapper 146 provides (releases) a collection path for collecting the cut sheet CS from the discharge port 191 toward the capture space 182, and the cut sheet CS is transferred from the discharge port 191 to the capture space 182. Sort towards.

  Further, the control unit 10 (pulse oscillator of the control unit 10) outputs a pulse signal to the second stepping motor 142M. The control unit 10 controls the second stepping motor 142M to reverse rotation, the second speed, and the second rotation angle. Further, the control unit 10 outputs a pulse signal to the third stepping motor 143M. The control unit 10 controls the third stepping motor 143M to perform reverse rotation, the first speed or the fourth speed higher than the first speed, and the fifth rotation angle larger than the second rotation angle. The second stepping motor 142M rotates backward by the second rotation angle at the second speed based on the pulse signal from the control unit 10. Further, the third stepping motor 143M rotates backward by the fifth rotation angle at the first speed or the fourth speed based on the pulse signal from the control unit 10. Correspondingly, the second transport unit 142 transports the sheet CS in the reverse direction by the second transport distance at the second speed (low speed). The third transport unit 143 transports the sheet CS in the reverse direction by the fifth transport distance at the first speed (normal speed) or the fourth speed (high speed) (ACT 46).

  Then, the sheet rear end (cut end) starts to be conveyed toward the first conveyance unit 141 at the second speed (low speed), and the sheet rear end hangs down due to the weight of the sheet rear end. Alternatively, the sheet trailing edge comes into contact with the first flapper 145 at the third position, and the sheet trailing edge is pushed down. Further, when the sheet trailing edge is pushed down, the third conveyance unit 143 pulls the sheet trailing edge and feeds the sheet CS to the capture space at the first speed or the fourth speed. As a result, the capture of the forgotten sheet CS is completed (ACT 47). Then, the control unit 10 returns the second flapper 146 to the home position (ACT 48).

  A sensor 148 that detects the conveyed sheet CS is provided between the second conveying unit 142 and the third conveying unit 143, and the sensor 148 detects the conveyed sheet CS. When the passage of the sheet CS is detected by the detection signal from the sensor 148, the next mode, for example, the normal conveyance mode or the looping conveyance mode can be executed. That is, even if the sheet CS is not completely accommodated in the capture space and a part of the sheet CS remains in the middle of the third transport unit 143, the printing operation for the next sheet can be executed.

  In addition, when the third transport unit 143 transports the sheet CS at the fourth speed, the sheet CS starts to be collected at a low speed by the second transport unit 142 at first, but when the rear end of the sheet reaches the third transport unit 143. The sheet CS is collected at a high speed by the third conveyance unit 143. For example, the sheet pinch pressure by the third conveyance unit 143 is set higher than the sheet pinch pressure by the second conveyance unit 142. Thereby, even if the second conveyance unit 142 is low-speed conveyance, the high-speed conveyance of the third conveyance unit 143 works effectively, and the sheet CS slides on the second conveyance unit 142 and is conveyed at high speed by the third conveyance unit 143 and collected. Is done.

  In addition, the control unit 10 changes the transport speed of the second transport unit 142 from the second low speed to the second speed in accordance with the transport speed of the third transport unit 143 in the process in which the second stepping motor 142M rotates backward by the second rotation angle. The speed may be changed to 1 or the fourth speed. For example, in the process, the conveyance speed of the second conveyance unit 142 is changed from the second low speed at the timing of reverse rotation to a certain rotation angle (for example, the rotation angle corresponding to the conveyance distance arbitrarily set between 1 cm to 10 cm). You may make it change into 1st or 4th speed. Alternatively, in the process, the conveyance speed of the second conveyance unit 142 may be changed from the second low speed to the first or fourth speed at the timing when the sensor 148 detects the trailing edge (cut edge) of the sheet. .

  In addition, the control unit 10 performs the second flapper 146 at the timing when the second stepping motor 142M rotates backward to a certain rotation angle (for example, the rotation angle corresponding to the conveyance distance of 5 cm) in the process of reverse rotation by the second rotation angle. In response to this, a positioning instruction to the fourth position is output. That is, as shown in FIG. 5, the second flapper 146 rotates to the fourth position and stops according to the positioning instruction from the control unit 10 to the fourth position. At this time, the trailing end of the hung sheet is pressed down by the second flapper 146. Thereby, it is possible to more reliably prevent the captured sheet CS from being erroneously collected in the looping space. For example, one end of the second flapper 146 includes a semi-circular sheet pressing member 146a, and the trailing edge of the sheet hanging down by the sheet pressing member 146a is pressed down. The sheet pressing member 146a is configured by an elastic member such as rubber.

  In the present embodiment, the case where the printer 1 includes the capture space 182 and collects the sheet CS that has been forgotten to be captured in the capture space has been described. However, the present invention is not limited to this. The printer 1 is composed of a housing, and there is an empty space in the housing. For example, an empty space exists at the bottom of the housing. Instead of the capture space 182, the empty space may be used to collect the forgotten sheet CS.

  Note that all the procedures of the above-described processing (each mode) can be executed by software. For this reason, the above-described processing can be easily realized only by installing and executing this program on the printer 1 through a computer-readable storage medium storing a program for executing the above-described processing procedure.

  For example, the program can be read from a computer-readable storage medium via the input unit 11, the read program can be stored in the storage unit 12, and the installation of the program can be completed. Alternatively, the program can be downloaded via the communication unit 13, the downloaded program can be stored in the storage unit 12, and the installation of the program can be completed. Thereby, the control part 10 of the printer 1 can implement | achieve the said process easily based on the said installed program.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention.
