It is inserted into the portion 36. Further, the tape core 32 of the cassette 30 is engaged with the tape core engaging shaft 22, and the ink ribbon winding core 35 is further engaged with the ink ribbon winding drive shaft 23.

When a printing instruction is input to the printing apparatus 1, the printing medium M is fed out from the tape core 32 by the rotation of the platen roller 21. At this time, the ink ribbon winding drive shaft 23 rotates in synchronization with the platen roller 21, so that the ink ribbon IR is fed out from the ink ribbon supply core 34 together with the print medium M. As a result, the print medium M and the ink ribbon IR are conveyed in an overlapping state. Then, when the ink ribbon IR is heated by the thermal head 10 when passing between the thermal head 10 and the platen roller 21, the ink is transferred to the printing medium M, and an image based on the print data is printed.

It includes a roller drive motor 43, a discharge motor drive circuit 44, and an encoder 49. The control device 5, ROM 6, and RAM 7 are examples of the computer of the printing device 1.

The control device 5 includes, for example, a processor 5a which is a CPU (Central Processing Unit). The control device 5 controls the operation of each part of the printing device 1 by expanding and executing the program stored in the ROM 6 in the RAM 7.

The control device 5 supplies, for example, control signals (strobe signal, latch signal, clock signal) and print data to the head drive circuit 9, and controls the thermal head 10 via the head drive circuit 9. Further, the control device 5 is a motor (stepping motor 12, cutter motor 15, discharge roller drive motor 43) via a motor drive circuit (conveyor motor drive circuit 11, cutter motor drive circuit 14, discharge motor drive circuit 44). To control.

As will be described in detail later, the control device 5 acquires information on the rotation angle of the drive discharge roller 41 from the encoder 49, except when the printed matter M1 separated from the print medium M is discharged (for example, the transfer of the print medium M). At the time), the discharge roller drive motor so that the non-contact region 41b shown in FIG. 10 of the drive discharge roller 41 faces the printed medium M so that the drive discharge roller 41 does not contact the printed medium M. Control 43. Further, the control device 5 controls the discharge roller drive motor 43 so that the drive discharge roller 41 rotates while contacting the printed matter M1 in the contact region 41a shown in FIG. 11 to discharge the printed matter M1 to the outside.

The ROM 6 stores a print program for printing on the print medium M and various data (for example, fonts and the like) necessary for executing the print program. The ROM 6 also functions as a storage medium in which a program readable by the control device 5 is stored.

The RAM 7 functions as a data memory for storing print data and information about printing.
The communication interface 8 exchanges data with an external device such as the print control device 80 by wired communication or wireless communication.

The thermal head 10 has a plurality of heat generating elements 10a arranged in the Y direction, which is the width direction (main scanning direction) of the print medium M. During the energization control period of the strobe signal supplied from the control device 5, the head drive circuit 9 selectively energizes the current supplied to the heat generating element 10a according to the print data, so that the heat generating element 10a generates heat. The ink ribbon IR is heated. As a result, the thermal head 10 prints one print line at a time on the print medium M by thermal transfer.

The transport motor drive circuit 11 drives the stepping motor 12. The stepping motor 12 is an example of a transport drive unit for transporting the print medium M, and rotates the platen roller 21. The platen roller 21 is rotated by the power of the stepping motor 12 to convey the print medium M in the X direction, which is the long direction (sub-scanning direction) of the print medium M.

The control device 83 has, for example, a processor 83a which is a CPU, and controls the operation of each part of the print control device 80.

The print data stored in the RAM 7 of the printing device 1 is input by, for example, the user performing an input operation of the print content on the input device 82 while looking at the print content input screen displayed on the display device 81. It is generated by the control device 83 based on the operation. Further, the generated print data is sent from the communication interface 87 of the print control device 80 to the communication interface 8 of the printing device 1 and stored in the RAM 7. When the printing device 1 has a display device or an input device, the control device 5 of the printing device 1 may generate print data based on a user's input operation. Alternatively, the printing device 1 may acquire print data from the storage medium inserted into the above-mentioned storage medium insertion slot provided in the device housing 2.

6 and 7 are perspective views showing the discharge roller unit 56.
8 and 9 are perspective views of the discharge roller unit 56 in which the discharge roller cover 55 is not shown.

10 and 11 are perspective views showing the drive discharge roller 41 and the driven discharge roller 42.
FIG. 12 is a plan view showing the drive discharge roller 41, and FIG. 13 is a plan view showing the drive discharge roller 61 in the modified example.

14 and 15 are schematic views for explaining the driven discharge roller 42.
The discharge roller unit 56 shown in FIGS. 6 and 7 includes, for example, four drive discharge rollers 41, for example, four driven discharge rollers 42, a discharge roller drive motor 43, a frame 48, an encoder 49, a gear train 50, a bearing 53, and a compression spring. 54, a discharge roller cover 55 and the like are provided.

As shown in FIGS. 8 to 11, each drive discharge roller 41 is spaced in the Y direction by being integrally molded with, for example, a single central shaft 45 extending in the Y direction, which is the width direction of the print medium M. Are connected to each other by a distance.
The central shaft 45 has a tubular shape, and a rotating shaft (first shaft) 46, which is the center of rotation of the drive discharge roller 41, is fitted therein. The rotation shaft 46 is provided along the Y direction, which is the width direction of the print medium M. As a result, the central shaft 45 and each drive discharge roller 41 rotate integrally with the rotation shaft 46 in the rotation direction D, which is clockwise in FIGS. 10 to 12.

As shown in FIGS. 10 to 12, the drive discharge roller 41 faces the contact region 41a provided on the outer peripheral surface of the drive discharge roller 41 so as to come into contact with the printed matter M1 when the printed matter M1 is discharged, and is separated from the printed medium M. The drive discharge roller 41 has a non-contact region 41b provided so as to be non-contact with the printed medium M. It is desirable that one contact region 41a and one non-contact region 41b are provided in the rotation direction D of the drive discharge roller 41. The non-contact region 41b is in non-contact with the print medium M over the entire width direction of the print medium M in the Y direction.

The drive discharge roller 41 exhibits, for example, a fan shape surrounding the central axis 45 in a plan view (that is, when viewed from above in the Y direction). In FIG. 12 (and FIG. 13 of a modified example described later), a two-dot chain line (imaginary line) indicates a circumferential portion having the same diameter as the contact region 41a (contact region 61a).

Here, the position of the drive discharge roller 41 in the rotation direction D when the non-contact region 41b faces the printed medium M (the driven discharge roller 42) and the drive discharge roller 41 is not in contact with the print medium M is set. The non-contact position P1 shown in FIG. 10 is used.

After the printed matter M1 is separated from the print medium M, the contact region 41a rotates while contacting the printed matter M1, so that the drive discharge roller 41 discharges the printed matter M1 to the outside. The position of the drive discharge roller 41 in the rotation direction D when the contact region 41a comes into contact with the printed matter M1 is defined as the contact position P2 shown in FIG.

As shown in FIGS. 10 to 12, the tip portion of the contact region 41a in the rotation direction D of the drive discharge roller 41 is, for example, a curved portion 41c that is chamfered into a curved surface and curved into a curved surface. This is because if the tip portion is an angular portion, the torque required to rotate the drive discharge roller 41 when the contact region 41a of the drive discharge roller 41 starts contacting the printed matter M1 is temporarily large. Therefore, this increase in torque is suppressed, and the rotation of the drive discharge roller 41 is smoothed.

The drive discharge roller 41 is continuously provided in a region where the non-contact region 41b in the rotation direction D has an angle θ with respect to the rotation center R of the rotation shaft 46, for example, 180 degrees or more. As a result, even if the position of the drive discharge roller 41 in the rotation direction D cannot be controlled accurately, the contact region 41a is prevented from unintentionally coming into contact with the print medium M.

The drive discharge roller 41 is not limited to the one having the above-mentioned fan shape, and has, for example, as shown in FIG. 13, a non-contact region 61b in which a part of the outer circular arc is notched in a plane. A drive discharge roller 61 or the like may be used. The drive discharge roller 61 may also have a curved portion 61c in which the tip portion of the contact region 61a in the rotation direction D is chamfered in a curved surface shape and curved in a curved surface shape, for example. The non-contact region 61b of the drive discharge roller 61 is continuously provided in a region where the angle θ of the rotation shaft 46 with respect to the rotation center R in the rotation direction D is less than 180 degrees.

As shown in FIGS. 8 and 9, the rotating shaft 46 of the drive discharge roller 41 penetrates the motor support portion 48a of the frame 48 on which the discharge roller drive motor 43 is mounted in the vicinity of the lower end. Further, the rotary shaft 46 is rotatably supported by the motor support portion 48a. The upper end of the rotating shaft 46 is also rotatably supported by the frame 48.

A friction spring 47 whose one end is fixed to the motor support portion 48a is wound around the central shaft 45, and the friction spring 47 imparts resistance to the rotation of the central shaft 45, that is, the rotation of the drive discharge roller 41. As a result, it is possible to suppress the drive discharge roller 41 from rotating due to inertia and improve the position accuracy of the drive discharge roller 41 in the rotation direction D.

The frame 48 has a motor support portion 48a and a spring receiving portion 48b, and is fixed to, for example, the device housing 2 shown in FIG. 4 or the like. As described above, the discharge roller drive motor 43 is mounted on the motor support portion 48a.

The discharge roller drive motor 43 is, for example, a DC motor. The output shaft 43a projecting downward from the discharge roller drive motor 43 penetrates the motor support portion 48a. Further, the output shaft 43a is provided with a gear 43b, and the gear 43b meshes with one of the gear trains 50 including the gear 50a provided on the rotating shaft 46 of the drive discharge roller 41. As a result, the power of the discharge roller drive motor 43 is transmitted to the rotating shaft 46 via the gear 43b and the gear train 50.

As shown in FIGS. 6 to 9, an encoder 49 is provided near the lower end of the rotating shaft 46. The encoder 49 has a slit disk 49a on which the slits 49a-1 shown in FIGS. 10 and 11 are formed, and a photo sensor 49b for detecting the slits 49a-1.

The slit disk 49a is arranged so as to rotate integrally with the rotating shaft 46, that is, integrally with the drive discharge roller 41. The photo sensor 49b detects the rotational position of the drive discharge roller 41 by detecting the slit 49a-1.

As shown in FIGS. 8 to 11, each driven discharge roller 42 is spaced in the Y direction, for example, by being integrally molded with a single central shaft 51 extending in the Y direction, which is the width direction of the print medium M. Are connected to each other by a distance. Further, each driven discharge roller 42 is positioned so as to face each drive discharge roller 41, and as the drive discharge roller 41 rotates in the rotation direction D, the contact region 41a of the drive discharge roller 41 or the sandwiched printed matter is sandwiched. Upon contact with M1, the drive discharge roller 41 rotates in the direction opposite to the rotation direction D (counterclockwise in FIGS. 10 and 11).

The central shaft 51 of the driven discharge roller 42 has a tubular shape, and a rotating shaft (second shaft) 52, which is the center of rotation of the driven discharge roller 42, is fitted inside. The rotation shaft 52 is provided along the Y direction, which is the width direction of the print medium M. As a result, the central shaft 51 and the rotating shaft 52 rotate integrally with the driven discharge roller 42.

As shown in FIGS. 8 and 9, the rotary shaft 52 is rotatably supported by a bearing 53 at the upper end and the lower end.
The bearing 53 includes an upper arm 53a that rotatably supports the upper end of the rotary shaft 52, a lower arm 53b that rotatably supports the lower end of the rotary shaft 52, and a spring recess 53c to which one end of the compression spring 54 is fixed. , Have. The other end of the compression spring 54 is fixed to the spring receiving portion 48b of the frame 48.

As shown in FIG. 14, the compression spring 54 attaches the driven discharge roller 42 via the bearing 53 in the direction in which the driven discharge roller 42 approaches the drive discharge roller 41 (Z direction, which is the thickness direction of the printed matter M1). Momentum. The driven discharge roller 42 is arranged so as to interfere with the drive discharge roller 41 at the contact position P2, that is, the contact region 41a when the compression spring 54 has a free length. However, the driven discharge roller 42 is in close contact with the drive discharge roller 41 and is pushed back by the drive discharge roller 41 to slightly compress the compression spring 54 against the urging force of the compression spring 54.

As shown in FIG. 15, when the printed matter M1 is sandwiched between the drive discharge roller 41 and the driven discharge roller 42 at the time of discharge, the driven discharge roller 42 is separated from the drive discharge roller 41 according to the thickness of the printed matter M1. It is pressed by the printed matter M1 in the (Z direction). As a result, the compression spring 54 is compressed. In this way, the bearing 53 and the compression spring 54 can adjust the gap between the driven discharge roller 42 and the drive discharge roller 41 according to the thickness of the printed matter M1.

As shown in FIGS. 6 and 7, the discharge roller cover 55 has a drive roller side facing surface 55a and a driven roller side facing surface 55b facing each other. The gap between the drive roller side facing surface 55a and the driven roller side facing surface 55b is a discharge path DP from which the printed matter M1 is discharged. The discharge roller cover 55 is fixed to, for example, a frame 48. The discharge roller cover 55 covers a part of the drive discharge roller 41 and forms a part of the discharge path DP for discharging the printed matter M1 cut by the full-cut device 16 to the outside. Further, the discharge roller cover 55 also functions as a driven roller cover by having the driven roller side facing surface 55b. The driven roller cover covers a part of the driven discharge roller 42 to form a part of the discharge path DP.

On the drive roller side facing surface 55a, an opening region 55c in which at least a part of the contact region 41a of each drive discharge roller 41 projects toward the discharge path DP side is aligned in the Y direction, which is the width direction of the print medium M, and is driven. The same number as the discharge rollers 41 are provided, and four are provided here. The non-contact region 41b does not protrude from the opening region 55c. Further, on the driven roller side facing surface 55b, an opening region 55d in which a part of the outer peripheral surface of each driven roller 42 projects toward the discharge path DP side is arranged in the Y direction, which is the width direction of the printed medium M, and is driven. The same number as the discharge rollers 42 are provided, and four are provided here.

Here, as shown in FIG. 6, in the Y direction, which is the width direction of the print medium M, the width of the drive discharge roller 41 is adjacent to the roller width L1, the width of the drive roller side facing surface 55a is adjacent to the opening area width L2. The gap between the two opening regions 55c and 55c is defined as the opening region spacing L3, and the gap between the two adjacent drive discharge rollers 41 and 41 is defined as the roller spacing L4. The sum of the roller width L1 and the roller spacing L4 coincides with the sum of the opening region width L2 and the opening region spacing L3.

The width of the print medium M used in the printing device 1 in the width direction (Y direction) is larger than the roller spacing L4 so that the printed matter M1 comes into contact with any of the drive discharge rollers 41. Further, the width of the print medium M is preferably larger than the opening region width L2 from the viewpoint of making it difficult for the curled print medium M to enter the opening region 55c. That is, the roller spacing L4 is set to a value smaller than the minimum value of the width of the print medium M used in the printing device 1. Further, the opening area width L2 is preferably set to a value smaller than the minimum value of the width of the print medium M used in the printing apparatus 1.

The width L1 and the interval L4 of the drive discharge roller 41 in the Y direction are the same as the width and the interval of the driven discharge roller 42 in the Y direction, and the opening region 55c of the drive roller side facing surface 55a. , The width L2 and the spacing L3 in the Y direction are the same as the width and spacing of the opening region 55d in the Y direction of the driven roller side facing surface 55b. That is, the roller width L1 of the drive discharge roller 41 is equal to the width of the driven discharge roller 42, the opening region width L2 of the opening region 55c is equal to the width of the opening region 55d, and the distance between the opening regions of the two adjacent opening regions 55c and 55c. L3 is equal to the distance between the two adjacent opening regions 55d and 55d, and the roller distance L4 between the two adjacent drive discharge rollers 41 and 41 is equal to the distance between the two adjacent driven discharge rollers 42 and 42.

The discharge roller cover 55 is formed with a lower end inclined surface 55e at the lower end of the discharge path DP, which is a gap between the drive roller side facing surface 55a and the driven roller side facing surface 55b. At the upstream end of the lower end inclined surface 55e in the X direction, the position in the Y direction is the same as the lower ends of the lowermost opening regions 55c and 55d. Further, the lower end inclined surface 55e is inclined so that the position in the Y direction is lowered toward the downstream side in the X direction.

The drive discharge roller 41 and the driven discharge roller 42 are arranged unevenly toward the lower end side in the discharge path DP, and the printed matter M1 shown in FIG. 15 is arranged in the Y direction from the vicinity of the center to the vicinity of the lower end in the Y direction of the discharge path DP. It is discharged while being sandwiched between the drive discharge roller 41 and the driven discharge roller 42. The number of the drive discharge roller 41 and the driven discharge roller 42 is not particularly limited, but may be one, for example. In that case, the single drive discharge roller 41 and the single driven discharge roller 42 may also be arranged unevenly toward the lower end side in the discharge path DP. Further, when the printed matter M1 (printed medium M) is centered in the Y direction and discharged (conveyed), the printed matter M1 (printed medium M) is centered in the drive discharge roller 41 and the driven discharge roller 42. It is preferable that the arrangement is biased toward the lower end side from the center position in the Y direction. This is because the printed matter M1 separated from the print medium M falls in the discharge path DP due to its own weight.

FIG. 16 is a flowchart for explaining the ejection operation of the printed matter M1.
17 to 19 are plan views of the internal structure of the printing apparatus 1 for explaining the ejection operation of the printed matter M1.

First, the control device 5 shown in FIG. 5 controls the stepping motor 12 via the transport motor drive circuit 11 to cause the platen roller 21 to transport the print medium M via the head drive circuit 9. By controlling the thermal head 10, the thermal head 10 is made to print the printing medium M. Further, the control device 5 controls the cutter motor 15 via the cutter motor drive circuit 14, so that the full-cut device 16 or the half-cut device 17 performs full-cut or half-cut of the print medium M.

As shown in FIG. 17, the control device 5 is a full-cut device in order to discharge the printed printed matter M1 separated from the printed medium M to the outside after the printed medium M is cut by the full-cut device 16. While the movable blade 16a of 16 is in the cutting position, the discharge roller drive roller 43 is controlled so as to rotate the drive discharge roller 41 in the rotation direction D by, for example, one rotation as shown in FIG. 18 (step S1 in FIG. 16). ..

The control device 5 sets the non-contact position P1 (see FIG. 10) of the drive discharge roller 41 when the slit 49a-1 of the slit disk 49a is detected by the photosensor 49b of the encoder 49 as the initial position, and prints the printed matter. The discharge roller drive motor 43 is controlled so that the drive discharge roller 41 is rotated once and returned to the initial position when the M1 is discharged.

That is, in the control device 5, the non-contact region 41b faces the printed medium M during the transfer of the printed medium M by the platen roller 21, so that the drive discharge roller 41 is not in contact with the printed medium M. In addition, the discharge roller drive motor 43 is controlled. When the power supply is suddenly stopped while the drive discharge roller 41 is in contact with the printed matter M1 at the contact position P2, the control device 5 determines whether the drive discharge roller 41 is in the initial position at the next start-up. If the detection is performed using the encoder 49 and the drive discharge roller 41 is not in the initial position, the discharge roller drive motor 43 may be controlled so as to rotate the drive discharge roller 41 to the initial position.

As shown in FIG. 18, in the X direction, the printed matter M1 having a length L5 or less between the contact position of the drive discharge roller 41 with the printed matter M1 and the cutting position by the full cutting device 16 is the drive discharge roller 41. Cannot be discharged. Therefore, it is desirable that the minimum length of the printed matter M1 that can be set in the printing apparatus 1 in the X direction is longer than the length L5.

As described above, since the non-contact position P1 of the drive discharge roller 41 when the slit 49a-1 of the slit disk 49a is detected by the photosensor 49b of the encoder 49 is set as the initial position, the drive discharge roller 41 rotates once. Then, when the slit 49a-1 of the slit disk 49a that rotates integrally with the drive discharge roller 41 is detected again by the photosensor 49b (step S2: YES), the control device 5 rotates the drive discharge roller 41. The discharge roller drive motor 43 is controlled so as to stop (step S3). As a result, as shown in FIG. 19, the printed matter M1 is discharged from the discharge port 2a of the device housing 2. After that, the control device 5 retracts the movable blade 16a of the full-cut device 16 from the cutting position.

Here, the rotation speed of the drive discharge roller 41 in the discharge operation is not limited to one rotation, and may be two or more rotations. When the printed matter M1 is discharged from the discharge port 2a of the apparatus housing 2 by its own weight when the printed matter M1 is separated from the printed medium M, the drive discharge roller 41 does not come into contact with the printed matter M1 and runs idle.

By the way, when the remaining amount of the print medium M becomes low, the terminal portion of the print medium M is not separated as the printed matter M1, but when it passes through the platen roller 21, it is not conveyed by the platen roller 21. Therefore, when the detection sensor for detecting the end of the printed matter M is arranged in the printing device 1, the control device 5 causes the drive discharge roller 41 to rotate at a higher speed (for example, one rotation) than when the printed matter M1 is discharged (for example, one rotation). For example, the discharge roller drive motor 43 may be controlled so as to rotate in 3 rotations). As a result, it is possible to prevent the end portion of the print medium M from being discharged by the drive discharge roller 41 and remaining in the vicinity of the full cut device 16. Therefore, when the printed medium M of the cassette 30 newly inserted into the cassette storage unit 19 is subsequently cut by the full-cut device 16, the terminal portions of the printed medium M remaining in the vicinity of the full-cut device 16 are together. It is also possible to prevent the strip-shaped dust from increasing due to being cut into pieces.

In the present embodiment described above, the printing apparatus 1 includes a thermal head 10 which is an example of a printing mechanism that prints on the printed medium M, and a printed printed medium on which printing is performed by the thermal head 10. It includes a full-cut device 16 which is an example of a cutting mechanism for cutting M, and a drive discharge roller 41 which discharges the printed matter M1 cut by the full-cut device 16 and separated from the print medium M to the outside. .. The drive discharge roller 41 is provided with a contact region 41a that can contact the printed matter M1 and a non-contact region 41b that does not contact the printed medium M on the outer peripheral surface thereof.

As a result, the non-contact region 41b faces the printed medium M except when the printed matter M1 is discharged, so that contact between the drive discharge roller 41 and the printed medium M or the driven discharge roller 42 can be avoided. it can. Since the contact between the drive discharge roller 41 and the printed medium M or the driven discharge roller 42 can be avoided in this way, at least of the drive discharge roller 41 and the driven discharge roller 42 other than when the printed matter M1 is discharged. Installation of a retracting mechanism for separating one from the other and bringing the printed matter M1 closer to the printed matter M1 can be omitted. As a result, it is possible to avoid complicated structure of the printing device 1, an increase in the number of parts, an increase in assembling man-hours, or an increase in the size of the printing device 1. Therefore, according to the present embodiment, the printed matter M1 separated from the print medium M can be discharged to the outside with a simple configuration.

Further, since the printed matter M1 can be forcibly discharged to the outside by the drive discharge roller 41, a structure such as the drive discharge roller 41 for forcibly discharging the printed matter M to the outside is not provided. In comparison with, for example, when the length of the printed matter M1 in the X direction is long, the tip of the printed matter M1 comes into contact with the installation surface of the printing device 1 and the printed matter M1 is not ejected by its own weight, so that the full-cut device 16 It is possible to prevent the printed matter M1 from remaining in the cut state. As a result, for example, when the printed matter M1 is created, when the printed matter M is half-cut by the half-cut device 17 through the cueing of the printed medium M, the remaining printed matter M1 is the printed medium M. It can also prevent half-cutting.

Further, in the present embodiment, the printing apparatus 1 includes a platen roller 21 which is an example of a transport mechanism for transporting the print medium M, and the drive discharge roller 41 is in the Y direction which is the width direction of the print medium M. The drive discharge roller 41 is rotated around a rotation shaft 46 (an example of the first shaft) provided along the rotation shaft 46, and when the platen roller 21 conveys the print medium M, the non-contact region 41b is the print medium M. When the printed matter M1 is discharged to the outside, the printed matter M1 is rotated at least once with the rotation shaft 46 as the center of rotation, and the contact region 41a becomes the printed matter during the rotation. Contact M1. Further, in the present embodiment, the printing device 1 comprises a discharge roller drive motor 43, which is an example of a discharge roller drive unit that rotates the drive discharge roller 41, and a control device 5 that controls the discharge roller drive motor 43. The control device 5 is provided with a discharge roller drive motor so that the drive discharge roller 41 is located at a position where the non-contact area 41b is separated from the print medium M and faces the print medium M when the platen roller 21 conveys the print medium M. The rotation of the drive discharge roller 41 is controlled by the 43. Further, the control device 5 rotates the drive discharge roller 41 at least once around the rotation shaft 46 when the printed matter M1 is discharged to the outside, and discharges the printed matter M1 to the outside. The rotation of the drive discharge roller 41 is controlled by the 43.

As a result, when the printed medium M is conveyed, the non-contact region 41b faces the printed medium M, so that a jam is generated due to the contact between the printed medium M and the drive discharge roller 41 and the driven discharge roller 42. It can be avoided. Further, by interlocking the drive discharge roller 41 and the driven discharge roller 42 with the platen roller 21, the drive discharge roller 41 and the driven discharge roller 42 also convey the printed medium M together with the platen roller 21. It is possible to avoid the installation of a complicated structure for interlocking the roller 41 with the platen roller 21. Therefore, the printed matter M1 can be discharged to the outside with a simple structure.

Further, in the present embodiment, the drive discharge roller 41 rotates in the rotation direction D in which the printed matter M1 can be discharged to the outside in a state where the contact region 41a is in contact with the printed matter M1, and the drive discharge roller 41 is on the outer peripheral surface of the drive discharge roller 41. The tip portion of the contact region 41a in the rotation direction D is curved (curved portion 41c). Therefore, as compared with the embodiment in which the tip portion of the contact region 41a in the rotation direction D is an angular portion, the drive discharge roller 41 and the driven discharge roller 41 when the contact region 41a of the drive discharge roller 41 starts contacting the printed matter M1. It is possible to suppress an increase in the torque required to rotate the 42.

Further, in the present embodiment, the printing device 1 covers a part of the drive discharge roller 41 to form a part of the discharge path DP for discharging the printed matter M1 cut by the full cut device 16 to the outside. A discharge roller cover 55 is provided. The discharge roller cover 55 has at least one opening region 55c provided so that at least a part of the contact region 41a on the outer peripheral surface of the drive discharge roller 41 projects toward the discharge path DP side and the non-contact region 41b does not project. .. Further, in the present embodiment, the rotation shaft 52 (an example of the second axis) provided at a position facing the drive discharge roller 41 along the Y direction, which is the width direction of the print medium M, rotates as the rotation center. The driven discharge roller 42 is provided with at least one driven discharge roller 42, which is capable of sandwiching the printed matter M1 between the contact area 41a of the drive discharge roller 41 and the driven discharge roller 42, and is capable of driving and discharging. The roller 41 is provided at a position where it does not come into contact with the non-contact region 41b. Further, in the present embodiment, the driven discharge roller 42 is urged in the direction approaching the drive discharge roller 41 (Z direction), and can move along the direction facing the drive discharge roller 41 (Z direction). is there. Further, in the present embodiment, the printing apparatus 1 includes a driven roller cover (discharge roller cover 55) that covers a part of the driven discharge roller 42 to form a part of the discharge path DP, and the driven roller cover is provided. The driven discharge roller 42 has at least one opening region 55d provided so that a part of the outer peripheral surface thereof projects toward the discharge path DP side. With the above configuration, the printed matter M1 can be discharged to the outside with a simple configuration.
