As shown in FIG. 5B, the base portion 51A has a substantially rectangular upper end surface extending in the front-rear direction 8 and the left-right direction 9. The upper end surface of the base portion 51A is located to the left of the first guide rail 81A, and has substantially the same vertical position as the upper end portion of the cover 90 and the lower end portion of the first guide rail 81A.

The first fixing member 82A, the guide lever support 83A, the guide lever 84A, and the guide lever stopper 86A are located on the upper end surface of the base portion 51A.

As shown in FIG. 5B, the first fixing member 82A is located substantially in the center of the peripheral edge portion 35A of the right surface 35 and the front end portion 81F of the first guide rail 81A in the front-rear direction 8. The first fixing member 82A is located slightly to the left of the first guide rail 81A in the left-right direction 9. From such a position, the first fixing member 82A projects upward from the base portion 51A (see FIG. 5A). One end of the lever spring 85A is locked to the upper end of the first fixing member 82A, and the lever spring 85A is fixed.

The guide lever support 83A is shown in FIG. 5B and has a cylindrical shape. The guide lever support 83A is separated forward from the first fixing member 82A in the front-rear direction 8, and has substantially the same position as the rear end portion of the peripheral edge portion 35A. The guide lever support 83A is slightly displaced to the left from the first fixing member 82A in the left-right direction 9. From such a position, the guide lever support 83A projects upward.

As shown in FIG. 5A, the guide lever stopper 86A has a rectangular parallelepiped shape protruding upward from the upper end surface of the base portion 51A, and has a front surface and a right surface. As shown in FIG. 5B, the front surface and the right surface of the guide lever stopper 86A are orthogonal to each other in the front-rear direction 8 and the left-right direction 9, and are located apart from the left side of the guide lever support 83A.

As shown in FIG. 5, the guide lever 84A has a thin plate-like shape in the vertical direction 7, and has an upper surface and a lower surface parallel to each other. As shown in FIG. 5B, the guide lever 84A is formed with a through hole 84T that penetrates in the vertical direction 7 and through which the guide lever support 83A is inserted. The through hole 84T has an oval shape in a plan view. Specifically, the width of the through hole 84T is substantially the same as the outer diameter of the guide lever support 83A, and the length thereof is slightly longer than the outer diameter of the guide lever support 83A. The guide lever 84A rotates about the axis of the guide lever support 83A on the upper end surface of the base 51A while the cover 90 slides between the closed position (see FIG. 1) and the open position (see FIG. 2). It is rotatable in direction 5 (see FIGS. 5 (B) to 7 (B)). Hereinafter, in the rotation direction 5, the clockwise and counterclockwise directions in a plan view are also referred to as "forward direction 5A" and "reverse direction 5B". Further, the rotation direction 5, the forward direction 5A, and the reverse direction 5B are also used when explaining the rotation directions around the other axial centers along the vertical direction 7.

An L-shaped notch 811 is formed on the peripheral edge of the guide lever 84A in a plan view. Specifically, the planar shape of the notch 811 generally corresponds to the planar shape of the front surface and the right surface of the guide lever stopper 86A. The notch 811 rotates about the axis of the guide lever support 83A between the separation position (see FIG. 5B) and the contact position (see FIGS. 6B and 7B). It is rotatable to 5. The separation position is a position separated from the guide lever stopper 86A in the reverse direction 5B when the cover 90 is in the closed position. The contact position is a position where the notch 811 comes into contact with the front surface and the right surface of the guide lever stopper 86A.

That is, in the second posture, the first guide pin 88A is farther from the spindle 19 than the right surface in the left-right direction 9.

The guide lever 84A takes the third posture while changing the posture from the first posture to the second posture. In the third posture, as shown in FIG. 6B, the rotation center of the guide lever 84A (that is, the guide lever support 83A) is aligned with one end and the other end of the lever spring 85A in a straight line.

The guide lever support 83A rotates the guide lever 84A so that the posture changes between the first posture (see FIG. 5B) and the second posture (see FIG. 7B) of the guide lever 84A. It is rotatably supported by 5. Further, the rotation center of the guide lever 84A is located between the virtual straight line 4A and the right surface 35 when the cover 90 is in the open position and the guide lever 84A is in the second posture (see FIG. 7B). .. The virtual straight line 4A is a straight line connecting the first fixing member 82A and the second fixing member 89A. The center of rotation of the guide lever 84A in the guide lever support 83A is on the right side 35 of the virtual straight line 4A when the cover 90 is in the closed position and the guide lever 84A is in the first posture (see FIG. 5B). It is in a close position. When the guide lever 84A is in the third posture, the guide lever support 83A is located on a virtual straight line 4A connecting the first fixing member 82A and the second fixing member 89A in a plan view from above.

The lever spring 85A is a coil spring. The lever spring 85A urges the guide lever 84A in the direction toward the first posture (that is, the reverse direction 5B) until the posture of the guide lever 84A changes from the first posture to the third posture. The lever spring 85A urges the guide lever 84A in the direction toward the second posture (that is, the forward direction 5A) until the posture of the guide lever 84A changes from the third posture to the second posture. As the lever spring 85A, a spring having another shape such as a torsion coil spring may be used instead of the coil spring.

As shown in FIG. 5A, the main body frame 50 further has a base portion 51B having a shape symmetrical with the base portion 51A in the vertical direction 7 with respect to the first reference surface 4. The first reference surface 4 is a virtual surface that includes the center of the cover 90 in the vertical direction 7 and extends along the front-rear direction 8 and the left-right direction 9.

[Structure of cover 90]
As shown in FIG. 5A, the cover 90 has a cover right surface 91R having a substantially rectangular shape when viewed from the right. The dimensions of the cover right surface 91R in the vertical direction 7 correspond to the distance between the first guide rails 81A and 81B, and the dimensions in the front-rear direction 8 correspond to the distance between the peripheral portions 35A of the right surface 35 as shown in FIG. It is slightly longer than the distance to the rear end of the body 14.

As shown in FIG. 6B, on the right side surface 91R of the cover, the front end portion 91F has a shape thinner in the left-right direction 9 than the other portions. Further, the peripheral edge portion 35A of the right surface 35 is displaced to the left by an amount corresponding to the thickness of the front end portion 91F in the left-right direction 9 from the portion of the right surface 35 excluding the peripheral edge portion 35A. When the cover 90 is in the closed position, the protrusion 91B (see FIGS. 6 (B) and 8) provided on the left surface of the front end 91F is formed in the peripheral edge 35A of the right surface 35 (FIG. 6). 6 (B), see FIG. 8). The protrusion 91B is an example of an engaging member. As a result, the cover 90 in the closed position does not shift in the left-right direction 9, and the right side surface 91R of the cover maintains a flat state with respect to the right side surface 35. Further, when the cover 90 is in the closed position, the cover left surface 91L opposite to the cover right surface 91R is located closer to the spindle 19 than the right surface 35 in the left-right direction 9.

As shown in FIG. 5, the cover 90 has a cylindrical second guide pin 93A, a second guide rail 94A, and a handle mechanism 38.

The second guide pin 93A is provided at a position close to the rear end of the upper end surface of the cover 90. Specifically, the second guide pin 93A is provided at a position substantially in contact with the rear end position Py2 of the first guide path 87A when the cover 90 is in the closed position. At such a position, the second guide pin 93A projects upward and fits into the first guide path 87A. As shown in FIG. 7B, the second guide pin 93A is located slightly behind the front end position Py1 of the first guide path 87A when the cover 90 is in the open position. The second guide pin 93A is an example of the second fitting portion. Further, when the cover 90 is in the open position, the left side surface 91L of the cover is farther from the spindle 19 than the right side surface 35 in the left-right direction 9.

As shown in FIGS. 5 to 7, the second guide rail 94A is located at the upper end of the cover 90. A first guide pin 88A (see FIG. 5) is fitted to the second guide rail 94A, and a second guide path 95A for guiding the sliding of the first guide pin 88A is formed. As shown in FIGS. 6B and 7B, the second guideway 95A is a bottomed groove extending in the front-rear direction 8 and opening upward. The width of the second guide path 95A is substantially the same as the outer diameter of the first guide pin 88A, and the first guide pin 88A fits into the second guide path 95A. The length of the second guideway 95A is, for example, greater than or equal to the front-rear distance between the front end position Py1 and the rear end position Py2 of the first guideway 87A.

The handle mechanism 38 has an arm 39 and a handle 310, as shown in FIGS. 5 and 8. The arm 39 is an example of an arm. The arm 39 and the handle 310 are housed in the recess 92 when not operated by the user.

[Operation of transport device 10]
Hereinafter, the image recording operation by the transfer device 10 will be described.
The transport device 10 that has received the print data controls a motor (not shown) to rotate the spindle 19, the feed roller 20, the first transport roller 60, and the second transport roller 62. As a result, the tip of the sheet of the roll body 11 is sent out below the print head 24. In the sheet of the roll body 11 that has been sent out, the sheet surface of the roll body 11 that faces outward in the radial direction faces the print head 24. Then, the transport device 10 discharges ink from the print head 24 toward the sheet based on the print data while rotating each roller.

The transport device 10 determines that printing based on the print data has been completed, and the sheet is drawn out from the roll body 11 until the printed portion comes out of the discharge port 13 to the outside of the housing 14. Then, a motor (not shown) is controlled to stop the rotation of the spindle 19, the feeding roller 20, the first transport roller 60, and the second transport roller 62.

[Opening and closing operation of cover 90]
When the sheet is used by printing and all the sheets are pulled out from the roll body 11 supported by the spindle 19, the roll body 11 is replaced by the user. In the replacement work of the roll body 11, the user slides the cover 90 in the closed position (see FIGS. 1 and 5) forward in the front-rear direction 8 to the open position (see FIGS. 2 and 7). .. The user may slide the cover 90 from the closed position to the open position even when the seat is clogged in the housing 14.

As shown in FIG. 5, when the cover 90 is in the closed position, the protrusion 91B (see FIG. 6B) of the cover 90 is fitted into the engagement hole 35H (see FIG. 6B) of the right surface 35. There is. The posture of the guide lever 84A is the first posture. The second guide pin 93A is located at the rear end position Py2 of the first guide path 87A. When the first guide pin 88A is located closer to the spindle 19 than the right surface 35 corresponding to the first posture, the front end portion of the second guide path 95A is in contact with the first guide pin 88A from the front. Therefore, the lever spring 85A applies an urging force of the reverse direction 5B to the guide lever 84A in the first posture, and the rotation of the first guide pin 88A to the forward direction 5A is restricted.

The user puts a finger on the rear end of the handle 310 and applies a forward force to slide the cover 90 from the closed position to the open position. As a result, the handle 310 is positioned with respect to the recess 92 in a state of protruding from the recess 92 after rotating in the positive direction 5A around the axis of the first rotation shaft 97 (see FIG. 8B). ). When the user begins to slide the cover 90 slightly forward from the closed position, the second guide pin 93A slightly to the right from the rear end position Py2 along the first guide path 87A, as shown in FIG. 6B. As it moves, the second guideway 95A also moves slightly to the right from the closed position. At this time, the guide lever 84A slightly moves to the right along the through hole 84T. That is, the cover 90 moves to the right to a position where it does not interfere with the right surface 35 in the left-right direction 9. Further, while the cover 90 starts to move from the closed position and the posture of the guide lever 84A changes from the first posture to the third posture, the guide lever 84A is urged in the reverse direction 5B by the lever spring 85A, while being urged in the reverse direction 5B. The force applied by the user causes the guide lever support 83A to rotate in the forward direction 5A around the guide lever support 83A. Therefore, the first guide pin 88A is driven by the guide lever 84A and rotates from the first posture to the third posture. If the user releases the handle 310 before the guide lever 84A changes its posture from the first posture to the third posture, the cover 90 is urged by the lever spring 85A in the opposite direction 5B to the lever spring 85A. Given, the cover 90 returns to the closed position.

When the posture of the guide lever 84A becomes the third posture due to the movement of the cover 90 (see FIG. 6B), the guide lever 84A starts to be urged to the forward direction 5A by the lever spring 85A. Further, the guide lever 84A rotates in the forward direction 5A around the guide lever support 83A by the urging force of the lever spring 85A and the force applied by the user. After that, as shown in FIG. 7B, the notch 811 comes into contact with the guide lever stopper 86A and then stops at the contact position. As a result, the guide lever 84A is in the second posture (see FIG. 7B), and as a result, the rotation of the first guide pin 88A is restricted and stopped.

After the cover 90 is in the state shown in FIG. 7B, the user slides the cover 90 to the open position to fully open the opening 18. Even if the user releases his / her hand from the handle 310 after the guide lever 84A changes its posture to the third posture, the cover 90 is given a positive 5A urging force to the lever spring 85A by the lever spring 85A. Therefore, the cover 90 moves to the open position. At this time, as shown in FIG. 7B, the second guide pin 93A is located immediately behind the front end position Py1 of the first guide path 87A. Further, the first guide pin 88A is in a position corresponding to the second posture, and the notch 811 is in a contact position.

With the cover 90 fully open, the user replaces the roll body 11 and clears the clogging of the sheet. After that, the user puts a finger on the front end portion of the handle 310 and applies a rearward force to slide the cover 90 from the open position to the closed position. As a result, the handle 310 is rotated about the second rotation shaft 98 in the opposite direction 5B, and then is positioned with respect to the recess 92 in a state of protruding from the recess 92 (see FIG. 8C). The user continues to apply a backward force to the handle 310 until the cover 90 reaches the closed position. When the cover 90 slides from the open position to the closed position, the slide mechanism 80 and the cover 90 only operate in the opposite direction to the above, and thus the description of each operation will be omitted.

[Action and effect of the embodiment]
According to the transport device 10, the cover 90 slides in the front-rear direction 8 between the closed position and the open position to open the opening 18 or close the opening 18. During this time, the cover 90 only moves to the right from the closed position to a position that does not interfere with the right surface 35 of the housing 14 in the left-right direction 9. Therefore, the space required on the right side of the transport device 10 is relatively small in order to slide the cover 90 to the open position when the roll body 11 is loaded on the spindle 19 or the sheet is jammed. When the guide lever 84A is in the first posture, the first guide pin 88A is located inside the right surface 35 of the housing 14. Therefore, when the cover 90 is in the closed position, the amount of the cover right surface 91R of the cover 90 protruding from the right surface 35 of the housing 14 is small.

Further, in the opening / closing operation of the cover 90, if the user releases the hand from the handle 310 before the guide lever 84A is in the third posture, the cover 90 is moved by the urging force of the reverse 5B by the lever spring 85A. Return to the closed position. That is, the transport device 10 has a function of keeping the cover 90 in the closed position. Further, even if the user releases his / her hand from the handle 310 after the guide lever 84A is in the third posture, the cover 90 moves to the open position due to the urging force of the lever spring 85A in the forward direction 5A. To do. Therefore, the user simply applies a force to the handle 310 from the first posture to the third posture of the guide lever 84A, and the cover 90 is opened. That is, the transport device 10 has a function of assisting the user in opening the cover 90.

On the contrary, the user simply applies a force to the handle 310 from the second posture to the third posture of the guide lever 84A, and the cover 90 is closed. That is, the transport device 10 has a function of assisting the user in opening the cover 90. When the handle is released from the second posture to the third posture of the guide lever 84A, the cover 90 returns to the open position. That is, the transport device 10 has a function of keeping the cover 90 in the open position.

As described above, according to the transport device 10, the user can easily open and close the cover 90, and the cover 90 is unlikely to remain open.

When the cover 90 is in the open position, the left side 91L of the cover is located closer to the spindle 19 than the right side 35. The left side surface 91L of the cover is located on the opposite side of the right side surface 91R of the cover 90. Therefore, when the cover 90 is in the closed position, the amount of the cover right surface 91R protruding from the right surface 35 of the housing 14 is small. When the cover 90 is in the open position, the left side 91L of the cover is farther from the spindle 19 than the right side 35.

Further, the cover 90 in the closed position is located on a virtual plane including the right side 35 of the housing 14. Therefore, since the cover 90 does not protrude to the left from the right surface 35, the set area of the transport device 10 is small. In addition, the appearance of the transport device 10 is good.

When the cover 90 is moved forward by the handle mechanism 38, the handle 310 rotates in the forward direction 5A around the first rotation shaft 97, and when the cover 90 is moved backward, the handle 310 is the first. 2 Rotates around the rotation shaft 98 in the opposite direction 5B. In this way, since the handle 310 rotates with respect to the cover 90 according to the moving direction of the cover 90, the user can easily operate the cover 90.

Further, since the opening 18 of the housing 14 does not expose the print head 24 to the outside, it is possible to prevent the user from inadvertently contacting the print head 24 through the opening 18.

Further, the open position of the cover 90 is downstream of the closed position in the transport direction. That is, the cover 90 is opened in the same direction as the sheet is discharged from the discharge port 13. Therefore, the user can easily operate the cover 90.

Further, in the above embodiment, the print head 24 that prints on the sheet by the inkjet method is used as the printing unit, but instead of this, an electrophotographic printing method or a thermal head is adopted. May be good. In that case, the heater 26 may be omitted if it is not necessary.

Further, in the above embodiment, the roll body 11 is supported by the spindle 19, but the rod-shaped support member that rotatably supports the roll body does not have to rotate like the spindle 19.

Further, the discharge port 13 does not necessarily have to be formed on the front surface 31 of the housing 14. For example, the discharge port 13 may be formed on the upper surface 33 of the housing 14, and the printed sheet passing through the discharge port 13 may be discharged diagonally upward or upward.

Further, the above-mentioned transport device 10 is used in a state where the front surface 31 and the rear surface 32 of the housing 14 are along the vertical direction 7 and the horizontal direction 9, but the usage posture of the transport device 10 is not limited to this.

Further, in the cover 90 in the closed position, the right surface 91R of the cover was flat with the right surface 35 without a step. However, not limited to this, the cover right surface 91R may be displaced to the left from the right surface 35 when the cover 90 is in the closed position.
