The present application is based on, and claims priority from JP Application Serial Number 2022-126866, filed Aug. 9, 2022, the disclosure of which is hereby incorporated by reference herein in its entirety.
The present disclosure relates to a printing apparatus.
Hitherto, various types of printing apparatuses have been used. Of these, some printing apparatuses perform printing while a medium is nipped between a roller pair and transported. For example, JP-A-2018-103476 discloses a printing apparatus that includes a roller pair for nipping and transporting a sheet and that includes, at an end thereof, a lever for switching a nipping state of the sheet between the roller pair.
However, in the printing apparatus of JP-A-2018-103476, the lever for switching the nipping state of the sheet between the roller pair is provided at the end in a width direction, and hence the lever is away from a position of a user when the sheet is set in the printing apparatus. Thus, in some cases, it is difficult for a user to set the sheet alone while the user presses the sheet. In particular, when the sheet is set in the printing apparatus, an end of the sheet in a width direction is easily bent. In a case in which a user in the vicinity of the end sets the sheet in the printing apparatus so as to avoid bending of the end, when the lever is provided at the end on the side opposite to the position of the user, it is particularly difficult for the user to set the sheet alone while the user presses the sheet. Therefore, in the related-art printing apparatus that performs printing while the medium is nipped between the roller pair and transported, operability for setting the medium is not always satisfactory.
In order to solve the above-mentioned problem, a printing apparatus according to the present disclosure includes an insertion port that is provided in a transport path of a medium and through which the medium is to be inserted, a roller pair configured to nip and transport the medium inserted through the insertion port, in the transport path, the roller pair comprises rollers facing each other, a printing unit configured to perform printing on the medium transported in the transport path by the roller pair, and a lever configured to switch a position of at least one roller of the roller pair between a nipping position where the roller pair is configured to nip the medium and a separation position where the roller pair does not nip the medium, in which a first lever as the lever is arranged within a range in which the medium transported by the roller pair is present, in a width direction intersecting with a transport direction of the medium.

With reference to the drawings, exemplary embodiments of the present disclosure are specifically described below. First, with reference to
As the printing apparatus 1, a printing apparatus 1A of the present exemplary embodiment includes a main body unit 2. Legs 13 are attached to both the end parts of the main body unit 2 in the X-axis direction. Further, the printing apparatus 1A of the present exemplary embodiment includes the holding unit 3 that holds the roll body R1 obtained by winding the medium M into a roll shape on a side in the −Y direction, which corresponds to the rear side of the main body unit 2. The holding unit 3 functions as a feeding unit that feeds the medium M being the roll body R1 to the main body unit 2, and is provided to an arm 14 attached to a pipe (not illustrated) for coupling the legs 13 on both sides in the X-axis direction to each other.
Further, in the printing apparatus 1A of the present exemplary embodiment, when the medium M is transported in a first direction A1 being a transport direction, the holding unit 3 including the rotation shaft along the X-axis direction rotates in a rotation direction C. Further, when the medium M is transported in a second direction A2 being a direction opposite to the first direction A1, the holding unit 3 including the rotation shaft along the X-axis direction rotates in a direction opposite to the rotation direction C. Note that, in the present exemplary embodiment, there is used the roll body R1 wound so that a printing surface on which an image is formed faces outward. When the roll body R1 wound so that the printing surface faces inward is used, the holding unit 3 can rotate in the direction opposite to the rotation direction C to feed the medium M from the roll body R1.
Further, the printing apparatus 1A of the present exemplary embodiment includes a transport path of the medium M. The transport path includes a medium support unit 4, a medium support unit 10, and a medium support unit 11 that support the medium M, and the like. Further, the printing apparatus 1A includes a roller pair 7 including a driving roller 5 and driven rollers 6 in the transport path, as a transport unit that transports the medium M in the first direction A1 and the second direction A2. Note that, in the printing apparatus 1A of the present exemplary embodiment, the driving roller 5 is configured as a roller extending in a width direction B intersecting with the first direction A1 and the second direction A2. The driven rollers 6 are a plurality of rollers that are provided and arrayed in the width direction B with respect to the driving roller 5 at positions facing the driving roller 5. However, the configuration of the transport unit is not limited thereto.
Further, the printing apparatus 1A of the present exemplary embodiment includes a head and a carriage 9 at a position facing the medium support unit 10. The head 8 is a printing unit that is provided with a plurality of nozzles and forms an image by ejecting ink from the nozzles. The carriage 9 is mounted with the head 8, and is reciprocally movable in the width direction B. The main body unit 2 including the head 8 is provided with a housing, which is omitted in
With the configuration described above, the head 8 is capable of forming an image by ejecting ink from the nozzles (not illustrated) onto the medium transported, while the head 8 reciprocates in the width direction B being a direction intersecting with the first direction A1 and the second direction A2. The printing apparatus 1A of the present exemplary embodiment is capable of forming a desired image on the medium M by repeating transport of the medium M by a predetermined transport amount in the first direction A1 and ejection of ink in a state in which the medium M is stopped while the head 8 moves in the width direction B. However, in place of the head thus configured, there may be adopted a configuration in which a so-called line head is included. In the line head, nozzles for ejecting ink are provided throughout in the X-axis direction.
Further, a holding unit 12 is provided downstream of the medium support unit 11 in the first direction A1. The holding unit 12 is a winding unit that winds the medium M transported in the first direction A1 into a roll shape to obtain a roll body R2. Note that, in the printing apparatus 1A of the present exemplary embodiment, the holding unit 3 and the holding unit 12 include similar configurations, and are configured to support paper tubes being rotation centers of the roll body R1 and the roll body R2 to rotate the paper tubes in the rotation direction C. The holding unit 12 is provided to an arm 15 attached to the pipe (not illustrated) for coupling the legs 13 on both sides in the X-axis direction.
In the printing apparatus 1A of the present exemplary embodiment, when the medium M is set before printing, a user causes the holding unit 3 to hold the roll body R1, causes the medium M to pass through between the driving roller 5 and the driven rollers 6 of the roller pair 7 via the insertion port 19, and feeds the leading edge of the medium M to the medium support unit 11. In this state, the gap between the driving roller 5 and the driven rollers 6 of the roller pair 7 is temporarily expanded, the medium M passes through the expanded gap, the leading edge of the medium M is fed to the medium support unit 11, and then the gap is narrowed. With this, the medium M is nipped between the driving roller 5 and the driven rollers 6. Here, when a user takes the hand off from the medium M without narrowing the gap after the leading edge of the medium M is fed to the medium support unit 11, there may be a risk that the medium M fed to the medium support unit 11 falls down onto the medium support unit 4 due to its own weight. In view of this, for facilitating narrowing of the gap after the leading edge of the medium M is fed to the medium support unit 11, the printing apparatus 1A of the present exemplary embodiment includes a lever 16 to be described later in detail. With this configuration, a user can easily expand or narrow the gap by moving the lever 16. In view of this, with reference to
As described above, the printing apparatus 1A of the present exemplary embodiment includes the insertion port 19 that is provided in the transport path of the medium M, the insertion port 19 through which the medium M is to be inserted. Further, the printing apparatus 1A of the present exemplary embodiment includes the roller pair 7 that nips and transports the medium M inserted through the insertion port 19, in the transport path, and the head 8 that performs printing on the medium M transported in the transport path by the roller pair 7. Further, as illustrated in
Thus, with the printing apparatus 1A of the present exemplary embodiment, a user can set the medium M alone while the user presses the medium M, and operability for setting the medium can be improved. Further, the first lever 16A is provided in the part close to the center of the printing apparatus 1A in the width direction B. Thus, even when a user is on either one of the end sides of the medium M in the width direction B to suppress bending of the end of the medium M in the width direction B, the user can perform setting alone while the user presses the medium M. Note that, in the configuration in which the media M having a plurality of different widths can be used in the printing apparatus 1, the expression “within the range in which the medium M transported by the roller pair 7 is present” may indicate a range in which the medium M having the maximum width is present. However, the range may be a range in which the medium M having a minimum width is present.
Here, with reference to
Further, the first lever 16A includes a fan-shaped toothed gear portion 63 at the base portion 162. Further, the driven rollers 6 of the roller pair 7 are provided to one end of an arm-shaped member 61 including a fan-shaped toothed gear portion 62 meshed with the toothed gear portion 63. When a user lifts up the handle portion 161 of the first lever 16A in a direction D1, the toothed gear portion 63 rotates in a rotation direction D2, and the toothed gear portion 62 rotates in a rotation direction D3. Then, the driven rollers 6 are lifted up in a direction D4. Note that, when a user presses down the handle portion 161 of the first lever 16A in a direction opposite to the direction D1, the toothed gear portion 62 and the toothed gear portion 63 rotate in directions opposite to the above-mentioned directions, and the driven rollers 6 are pressed down in a direction opposite to the direction D4. However, the shape of the first lever 16A is not particularly limited.
Note that on a side close to the base portion 162 of the first lever 16A, a foreign matter capturing unit 17 is attached. To the foreign matter capturing unit 17, cloth 171 for adsorbing a foreign matter or the like is attached. When a user lifts up the handle portion 161 of the first lever 16A in the direction D1, the foreign matter capturing unit 17 is away from the transport path of the medium M. When a user presses down the handle portion 161 of the first lever 16A in the direction opposite to the direction D1, the foreign matter capturing unit 17 approaches the transport path of the medium M. A user can replace the cloth 171 for adsorbing a foreign matter at a position at which the foreign matter capturing unit 17 is away from the transport path of the medium M.
Further, in the printing apparatus 1A of the present exemplary embodiment, as illustrated in
Here, the height at which the insertion port 19 is arranged may be 1,000 mm or lower. This is because a user can easily insert the medium M through the insertion port 19 while the user squats down. Meanwhile, the height at which the insertion port 19 is arranged may be 300 mm or higher. When the height is lower than 300 mm, a user cannot easily insert the medium M through the insertion port 19 while the user squats down.
Further, the first lever 16A may be arranged at the center of the printing apparatus 1A in the width direction B, or at a position within 22 inches from the center. With this configuration, a user easily reaches the first lever 16A by hand. In particular, even when a user is on either one of the end sides of the medium M in the width direction B to suppress bending of the end of the medium M in the width direction B, the user can easily reach the first lever 16A by hand.
Note that the printing apparatus 1A of the present exemplary embodiment is configured so that the medium M measuring 44 inches or larger in the width direction B can be used. In general, in a configuration in which the medium M having a large width of 44 inches or larger in the width direction can be used, operability for setting the medium M is easily degraded. However, in the printing apparatus 1A of the present exemplary embodiment, even when the medium M measuring 44 inches or larger in the width direction is used, a user can easily reach the first lever 16A by hand, and operability for setting the medium M is improved.
Further, as illustrated in
Further, the first lever 16A is configured to switch the foreign matter capturing unit 17 between the foreign matter capturing position and the retracting position, in conjunction of displacement of the position of the driving roller 5 and the driven rollers 6 that are the facing rollers of the roller pair 7. With this configuration, switching of the foreign matter capturing unit 17 can be particularly facilitated.
