As shown in fig. 1 and 2, the printer 1 according to the embodiment is a so-called large format printer, and can mount a large-sized printing medium N. The printer 1 has a liquid ejecting head 34 capable of ejecting ink as one example of liquid, and has a printing function of printing an image on a printing medium N illustrated by a two-dot chain line in the drawing by ejecting ink from the liquid ejecting head 34. The printer 1 includes a Contact Image Sensor (CIS) module 60 capable of reading an image of the document medium M indicated by a two-dot chain line in the drawing, and the CIS module 60 has a scanner function of reading an image formed on the document medium M.

In addition, the liquid ejection head 34 is an example of a liquid ejection section in the present application. The CIS module 60 is an example of a reading section in the present application.

The printer 1 includes a leg portion 11 and a frame portion 12 supported by the leg portion 11. The housing portion 12 has a scanner cover 15 that becomes the front surface of the housing portion 12, an insertion port 16 into which the document medium M is inserted, and a discharge port 17 from which the document medium M is discharged, on the apparatus front surface side (+ Y direction side).

The scanner cover 15 constitutes a front surface of the housing 12, and is rotatable about a cover shaft 18 (see fig. 3 and 4) extending in the X-axis direction between a closed position P1 shown in fig. 1 and an open position P2 shown in fig. 2. That is, the printer 1 according to the present embodiment includes the scanner cover 15, and the scanner cover 15 constitutes the front surface of the housing portion 12 and is rotatable about the cover shaft 18 between an open position P2 at which the CIS module 60 is opened and a closed position P1 at which the CIS module 60 is covered.

Since the hood axis 18 extends in the X-axis direction, the hood axis 18 direction is parallel to the X-axis direction. Therefore, the axial direction of the cover shaft in the present application is the X-axis direction in the present embodiment.

A CIS module 60 is provided on the scanner cover 15, and the CIS module 60 reads a document medium M conveyed in a conveyance direction TD (see fig. 4). The CIS module 60 is rotatable together with the scanner housing 15.

The CIS modules 60 are arranged in plural along the X axis direction. By arranging the plurality of CIS modules 60 along the X-axis direction, the CIS modules 60 can collectively read images of the document medium M conveyed from the insertion port 16 toward the discharge port 17.

When the scanner cover 15 is disposed at the covering position P1 as shown in fig. 1, the CIS module 60 is covered by the scanner cover 15, and external light does not enter the CIS module 60. The document medium M is in Contact with a Contact glass (Contact glass)61 (see fig. 4) of the CIS module 60, and the CIS module 60 can read an image of the document medium M.

In this manner, when the scanner cover 15 is disposed at the closed position P1, the CIS module 60 can read an image of the document medium M.

When the scanner cover 15 is disposed at the open position P2 as shown in fig. 2, the CIS module 60 is exposed, and the user can perform maintenance work on the CIS module 60.

In detail, as described later, in fig. 4, components arranged on the left side (+ Y direction side) with respect to an arrow mark (conveyance direction TD) of a thick broken line are provided on the scanner cover 15 and are rotatable together with the scanner cover 15. When the scanner cover 15 is disposed at the open position P2, the user can contact the CIS module 60 from the outside (from the upper side), and the user can perform maintenance work on the CIS module 60. That is, the state in which the CIS module 60 is exposed means a state in which the user can contact the CIS module 60 from the outside.

For example, when foreign matter (e.g., paper dust) or dirt adheres to the contact glass 61 of the CIS module 60, the user can place the scanner cover 15 at the open position P2 and perform maintenance work for removing the foreign matter or dirt from the contact glass 61.

In the present embodiment, the CIS module 60 is provided on the scanner cover 15, but the configuration is not limited to the configuration in which the CIS module 60 is provided on the scanner cover 15, and the configuration in which the CIS module 60 is provided on a component other than the scanner cover 15 may be employed.

For example, the CIS module 60 may be provided on the fixing portion 14 (see fig. 3 and 4) disposed to face the scanner cover 15 in a state where the scanner cover 15 is disposed at the closed position P1.

In the printer 1 according to the present embodiment, since the CIS module 60 is provided on the scanner cover 15, the scanner cover 15 is rotated forward (+ Y direction) or backward (-Y direction), whereby switching between a state in which the CIS module 60 can read an image of the document medium M and a state in which maintenance of the CIS module 60 can be performed.

The liquid container 70 includes a main body 72 for containing ink, an inlet port 71 through which ink can be injected from a refill container 80 (see fig. 5), and a lid member 73. The cover member 73 can rotate one end as a rotation axis and the other end with respect to the body portion 72. The lid member 73 seals the injection port 71, thereby suppressing drying of the ink stored in the main body 72. As described above, the printer 1 according to the present embodiment includes the liquid container 70 provided with the inlet 71 for ink.

The inlet 71 of the liquid container 70 is disposed on the right side with respect to the scanner cover 15. That is, the present embodiment has a structure in which the scanner cover 15 and the inlet 71 of the liquid container 70 are located at different positions in the X-axis direction.

The inlet 71 of the liquid container 70 is disposed below (in the (-Z direction) of the scanner cover 15. In other words, the scanner cover 15 is disposed above (in the + Z direction) the inlet 71 of the liquid container 70.

The housing 12 houses: a placement unit 25 for placing a roll body R formed by winding a long print medium N into a roll shape; a printing unit 30 (liquid ejection head 34) that prints an image on a printing medium N; a scanner unit 50 that reads an image formed on the original medium M; a control unit (20); and a liquid supply mechanism 40.

As described above, the printer 1 according to the present embodiment includes the housing 12 in which the liquid storage container 70 is mounted and which stores the liquid ejecting head 34 and the liquid supply mechanism 40.

The placement portion 25 is disposed at the upper rear portion in the drawing, and has a support portion 26 that supports the roll body R. The roll R rotates counterclockwise, and the printing medium N is unwound from the setting portion 25.

The control unit 20 is arranged at the upper right in the drawing. The control unit 20 includes a CPU (not shown) for controlling each unit of the printer 1, a memory (not shown) such as a RAM and a ROM, and the like. The memory stores programs run by the CPU, calculation results of the CPU, and the like. The control unit 20 controls each unit of the printer 1. For example, the control unit 20 controls the CIS module 60 and the roller pairs 51 and 56 (see fig. 4) described later.

The liquid supply mechanism 40 is disposed rearward with respect to the liquid container 70, and includes a liquid feed pump (not shown). The liquid feeding pump of the liquid supply mechanism 40 is constituted by a tube pump, a diaphragm pump, or the like.

The liquid supply mechanism 40 is connected to the liquid storage container 70 via an ink tube (not shown), and is connected to the liquid ejecting head 34 via an ink tube 41. The ink stored in the liquid storage container 70 is pressurized by the liquid feeding pump of the liquid supply mechanism 40 and is supplied to the liquid ejecting head 34.

As described above, the printer 1 according to the present embodiment includes the liquid supply mechanism 40, and the liquid supply mechanism 40 is configured to supply the ink stored in the liquid storage container 70 to the liquid ejecting head 34.

As shown in fig. 3 and 4, the printing unit 30 includes a printing transport unit 36 and a printing unit 31, the printing transport unit 36 transports the printing medium N fed out from the setting unit 25 to the printing unit 31, and the printing unit 31 forms an image on the printing medium N.

The printing transport unit 36 includes a printing transport roller 37 and a printing transport motor (not shown) that drives the printing transport roller 37. The printing transport unit 36 transports the printing medium N unwound from the setting unit 25 toward the liquid ejecting head 34. Further, a portion of the printing medium N disposed to face the liquid ejecting head 34 is conveyed in the + Y direction by the printing conveying unit 36.

The printing unit 31 includes: a guide shaft 32 extending in the X-axis direction; a carriage 33 supported by the guide shaft 32; a printing motor (not shown) that reciprocates the carriage 33 along the guide shaft 32; and a liquid ejecting head 34 that ejects ink to the printing medium N.

The carriage 33 is supported by the guide shaft 32 and is movable in the X-axis direction. The liquid ejecting head 34 is mounted on the carriage 33 and is movable in the X-axis direction together with the carriage 33.

The printing unit 30 alternately repeats an operation of ejecting ink onto the printing medium N while moving the liquid ejecting head 34 in the X-axis direction and an operation of conveying a portion of the printing medium N disposed opposite the liquid ejecting head 34 in the + Y direction by the printing conveying unit 36, thereby forming an image on the printing medium N.

The printing medium N on which the image is formed is discharged from a discharge port 39 arranged in the + Y direction with respect to the liquid ejecting head 34 to the outside of the housing portion 12.

An insertion port 16 into which the document medium M is inserted is provided at an upper front portion of the frame portion 12, and a discharge port 17 from which the document medium M is discharged is provided at a lower front portion of the frame portion 12.

The original medium M inserted from the insertion port 16 passes through a conveyance path of the original medium M formed in the housing 12 and is discharged from the discharge port 17. Then, in the conveyance path of the original medium M formed in the frame portion 12, the direction from the insertion port 16 toward the discharge port 17 is the conveyance direction in which the original medium M is conveyed.

The conveyance direction in which the original medium M is conveyed is an example of the conveyance direction in the present application, and is hereinafter referred to as a conveyance direction TD. In fig. 4, the conveyance direction TD is indicated by a thick broken arrow.

The housing 12 has a fixing portion 14, and the fixing portion 14 is disposed to face the scanner cover 15 in a state where the scanner cover 15 is located at the covering position P1. The fixing portion 14 has a baffle plate 13 disposed below.

The scanner unit 50 has: a first roller pair 51 disposed on the upstream side in the conveyance direction TD; a second roller pair 56 disposed downstream in the conveyance direction TD; and a CIS module 60 disposed between the first roller pair 51 and the second roller pair 56. In this way, the printer 1 includes the second roller pair 56, and the second roller pair 56 is disposed on the downstream side in the transport direction TD from the CIS module 60.

In addition, the second roller pair 56 is an example of a roller pair in the present application.

In a state where the scanner cover 15 is located at the covering position P1, the surface on the-Y direction side of the scanner cover 15 is the inner surface 15a of the scanner cover 15, and the surface on the + Y direction side of the fixing portion 14 is the inner surface 14a of the fixing portion 14. The inner surface 15a of the scanner cover 15 and the inner surface 14a of the fixing portion 14 are disposed to face each other, and a gap (space) through which the document medium M can be conveyed is formed between the inner surface 15a of the scanner cover 15 and the inner surface 14a of the fixing portion 14. The original medium M passes through a space between the inner surface 15a of the scanner cover 15 and the inner surface 14a of the fixed portion 14, and is conveyed in a direction from the insertion port 16 toward the discharge port 17. That is, a space between the inner surface 15a of the scanner cover 15 and the inner surface 14a of the fixing portion 14 forms a conveyance path of the document medium M.

In this manner, the inner surface 15a of the scanner cover 15 forms the conveyance path of the document medium M in a state where the scanner cover 15 is located at the closed position P1. Further, since the scanner cover 15 is disposed above (in the + Z direction) the inlet port 71 of the liquid container 70, the inner surface 15a of the scanner cover 15 constituting the conveyance path is located above (in the + Z direction) the inlet port 71 of the liquid container 70 in a state where the scanner cover 15 is located at the open position P2. That is, in the present embodiment, in a state where the scanner cover 15 is located at the open position P2, the inner surface 15a of the scanner cover 15 constituting the conveyance path is located above the inlet port 71 of the liquid storage container 70.

The first roller pair 51 is disposed near the insertion port 16, and conveys the document medium M inserted into the housing 12 from the insertion port 16 toward the CIS module 60.

The first roller pair 51 has a first driving roller 52, a first driven roller 53, and a second driven roller 54. The first driving roller 52 rotates with a shaft 52a extending in the X-axis direction as a rotation shaft. The first driven roller 53 rotates with a shaft 53a extending in the X-axis direction as a rotation axis. The second driven roller 54 rotates with a shaft 54a extending in the X-axis direction as a rotation axis.

The first driving roller 52 is provided on the fixing portion 14. The first driven roller 53 and the second driven roller 54 are provided on the scanner cover 15 and are rotatable together with the scanner cover 15.

The driven rollers 53 and 54 are pressed against the first driving roller 52 via the document medium M and driven to rotate. The first driving roller 52 nips the document medium M between the driven rollers 53 and 54. The first driving roller 52 is rotationally driven, and the original medium M is fed out to a conveyance path formed by the inner surface 15a of the scanner cover 15 and the inner surface 14a of the fixing portion 14.

The document medium M fed by the first roller pair 51 is conveyed in the conveyance direction TD along a conveyance path formed by the inner surface 15a of the scanner cover 15 and the inner surface 14a of the fixing portion 14, and is guided to the CIS module 60.

In fig. 4, components arranged on the left side (+ Y direction side) with respect to the conveyance direction TD indicated by a thick broken line arrow in the drawing are provided on the scanner cover 15 and are rotatable together with the scanner cover 15. For example, in addition to the first driven roller 53, the second driven roller 54, and the CIS module 60 described above, the third driven roller 58 is provided on the scanner cover 15 and is rotatable together with the scanner cover 15.

In fig. 4, components arranged on the right side (on the side of the (-Y direction) with respect to the conveyance direction TD indicated by a thick broken line arrow in the figure are provided in the fixed portion 14.

The CIS module 60 is disposed on the downstream side of the first roller pair 51 in the transport direction TD. The CIS module 60 includes: a contact glass 61 which is brought into contact with the original medium M; a light source (not shown) such as an LED for irradiating the document medium M with light; and a light receiving element (not shown) such as a CMOS sensor that receives the reflected light from the document medium M.

In a state where the scanner cover 15 is located at the closing position P1, the document medium M conveyed in the conveyance direction TD by the first roller pair 51 is conveyed to the second roller pair 56 disposed on the downstream side in the conveyance direction TD of the CIS module 60 after the image is read by the CIS module 60.

The second roller pair 56 has a second driving roller 57 and a third driven roller 58. The second driving roller 57 rotates with a shaft 57a extending in the X-axis direction as a rotation shaft. The third driven roller 58 rotates with a shaft 58a extending in the X-axis direction as a rotation axis. The second driving roller 57 is provided on the fixing portion 14. The third driven roller 58 is provided on the scanner cover 15 and is capable of rotating together with the scanner cover 15.

Further, since the shafts 57a, 58a of the rollers 57, 58 constituting the second roller pair 56 extend in the X-axis direction, the shafts 57a, 58a of the second roller pair 56 are parallel to the X-axis direction. Therefore, the axial direction of the roller pair in the present application is the X-axis direction in the present embodiment.

The third driven roller 58 is pressed against the second driving roller 57 via the document medium M and is driven to rotate. When the second driving roller 57 rotates, the third driven roller 58 is driven to rotate, and the document medium M is conveyed in the conveyance direction TD. When the rotation of the second driving roller 57 is stopped, the document medium M is sandwiched between the second driving roller 57 and the third driven roller 58. The document medium M nipped by the second driving roller 57 and the third driven roller 58 is held by the second roller pair 56. In this way, the second roller pair 56 has a holding function of holding the document medium M on which the image is read by the CIS module 60.

Further, in the X-axis direction, a nip position where the document medium M is nipped by the second driving roller 57 and the third driven roller 58, that is, a nip position where the document medium M is nipped by the second roller pair 56 is located at a position different from the inlet port 71 of the liquid container 70.

The document medium M conveyed by the second roller pair 56 is guided by the flapper 13 disposed in the-Z direction with respect to the second roller pair 56. The end portion of the document medium M on the downstream side in the conveyance direction TD abuts on the guide surface 13a of the flapper 13 and travels along the guide surface 13a of the flapper 13. As a result, the conveyance direction TD of the document medium M changes from the-Z direction (gravity direction) to the direction toward the discharge port 17 (+ Y direction).

Then, the document medium M on which the image is read by the CIS module 60 is discharged from the discharge port 17 to the outside of the housing portion 12.

The control unit 20 controls the first roller pair 51, the second roller pair 56, and the CIS module 60 such that the document medium M on which an image is read by the CIS module 60 is held by the second roller pair 56. That is, the control unit 20 holds the document medium M whose reading by the CIS module 60 is completed by the second roller pair 56. The second roller pair 56 holds the document medium M when the second roller pair 56 holds the document medium M and stops the rotation of the second roller pair 56.

In this way, the document medium M whose reading is completed by the CIS module 60 is not discharged from the discharge port 17 to the outside of the housing 12 and falls in the gravity direction (-Z direction), but is held by the second roller pair 56.

If a contamination source (for example, contamination of the floor surface) is present in the gravity direction with respect to the discharge port 17, when the original document medium M whose reading by the CIS module 60 is completed falls in the gravity direction, there is a possibility that the original document medium M is contaminated by the contamination source. In the present embodiment, since the document medium M whose reading by the CIS module 60 is completed is held by the second roller pair 56, even if a contamination source is present in the gravity direction with respect to the discharge port 17, the document medium M is less likely to be contaminated by the contamination source.

1.2 ink injection method

Next, an ink injection method according to the present embodiment will be described with reference to fig. 5.

In the printer 1 according to the present embodiment, since the scanner cover 15 provided with the CIS module 60 and the liquid storage container 70 provided with the inlet port 71 are provided in front of the apparatus, the user performs maintenance work of the CIS module 60 and injection work of ink into the liquid storage container 70 from the front of the apparatus.

When the user injects ink into the liquid container 70, the cover member 75 is opened from the front of the apparatus and the liquid container 70 is attached to the housing portion 12. Specifically, as shown in fig. 5, the liquid container 70 is attached to the housing portion 12 such that the inlet 71 of the liquid container 70 is positioned outside the housing portion 12 and the inlet 71 of the liquid container 70 is positioned at a position different from the scanner cover 15 (see fig. 1 and 2) in the X-axis direction.

The injection port 71 of the liquid container 70 is located outside the housing portion 12, which means that the user can inject ink through the injection port 71 of the liquid container 70 in a state where the liquid container 70 is attached to the housing portion 12.

As described above, when the liquid container 70 is mounted on the housing 12, the inner surface 15a of the scanner cover 15 constituting the conveyance path is located above the inlet port 71 of the liquid container 70 in a state where the scanner cover 15 is located at the open position P2.

When the liquid container 70 is mounted on the housing 12, the nipping position at which the document medium M is nipped by the second roller pair 56 is arranged on the left side with respect to the inlet 71 of the liquid container 70 in the X-axis direction, and is located at a position different from the inlet 71 of the liquid container 70.

In a state where the liquid container 70 is attached to the housing portion 12, the user turns the lid member 73 so that the injection port 71 is opened from a state where the injection port 71 is sealed. Next, the user moves the distal end of the refill container 80 to the vicinity of the inlet port 71 of the liquid container 70, and injects the ink from the refill container 80 into the liquid container 70. When the injection of the ink into the liquid container 70 is completed, the user pulls the distal end of the refill container 80 away from the injection port 71 of the liquid container 70. Finally, the user turns the lid member 73, and the injection port 71 is sealed from a state in which the injection port 71 is opened.

As described above, in the ink injection method according to the present embodiment, the liquid container 70 is attached to the housing portion 12 such that the injection port 71 is located outside the housing portion 12 and the injection port 71 is located at a position different from the scanner cover 15 in the X-axis direction, and the ink is injected into the liquid container 70 through the injection port 71.

As described above, when foreign matter such as paper dust or dirt adheres to the contact glass 61 of the CIS module 60 and the CIS module 60 cannot properly read the image of the document medium M, the user performs maintenance work for returning the CIS module 60 to a normal state from the front of the apparatus.

Specifically, when the CIS module 60 cannot properly acquire an image of the document medium M, the user rotates the scanner cover 15 from the cover position P1 to the open position P2, and exposes the contact glass 61 of the CIS module 60. The user removes foreign substances or dirt attached to the contact glass 61 using an air gun, a wiper, or the like. Finally, the user rotates the scanner cover 15 from the open position P2 to the closed position P1, and returns the CIS module 60 to a state in which the image of the document medium M can be properly read.

When the jam of the document medium M occurs in the conveyance path, the user performs a maintenance operation for removing the jam of the document medium M from the front of the apparatus.

Specifically, when a jam of the document medium M occurs in the conveyance path, the user rotates the scanner cover 15 from the cover position P1 to the open position P2, and takes out the document medium M that has become a jam in the conveyance path. Finally, the user rotates the scanner cover 15 from the open position P2 to the closed position P1, and returns the document medium M to a state in which it can be conveyed toward the CIS module 60.

In this way, the ink injection operation for injecting ink into the liquid container 70 is performed from the front of the apparatus. Further, the maintenance work for returning the CIS module 60 to the normal state and the maintenance work for removing the jam of the document medium M in the conveyance path are performed from the front of the apparatus while opening and closing the scanner cover 15.

In the printer 1 according to the present embodiment, since the scanner cover 15 and the inlet 71 of the liquid container 70 are located at different positions in the X-axis direction, even if the ink injection operation and the maintenance operation requiring opening and closing of the scanner cover 15 are performed simultaneously, these operations do not interfere with each other, and the operability does not deteriorate.

Therefore, the printer 1 according to the present embodiment can simultaneously perform the ink injection operation and the maintenance operation without deteriorating the operability. Therefore, the user can select the case of performing only the maintenance operation or the case of performing both the maintenance operation and the ink injection operation by observing the load state of the apparatus or the load state of the service.

As a result, the maintenance work, the ink injection work, and other ancillary works can be efficiently performed, and the down time of the printer 1 can be shortened.

In the ink injection method according to the present embodiment, when the injection of the ink into the liquid container 70 is completed and the user pulls the distal end of the refill container 80 away from the injection port 71 of the liquid container 70, the ink may be scattered from the injection port 71.

For example, in the case where the maintenance work for the CIS module 60 and the ink injection work for injecting ink into the liquid storage container 70 are simultaneously performed in the state where the scanner cover 15 is located at the open position P2, in the present embodiment, in the state where the scanner cover 15 is located at the open position P2, since the inner surface 15a constituting the transport path in the scanner cover 15 is located above the injection port 71 of the liquid storage container 70, even if ink is scattered from the injection port 71, the scattered ink is less likely to adhere to the inner surface 15a of the scanner cover 15. Specifically, even if ink is scattered from the inlet port 71, the scattered ink tends to travel in the direction of gravity, and therefore, the ink is less likely to adhere to the inner surface 15a of the scanner cover 15 that is located in the direction opposite to the direction of gravity with respect to the inlet port 71.

Therefore, the conveyance path formed between the inner surface 15a of the scanner cover 15 and the inner surface 14a of the fixing portion 14 is not contaminated by ink, and thus, a state is maintained in which the original medium M is appropriately conveyed along the conveyance path formed between the inner surface 15a of the scanner cover 15 and the inner surface 14a of the fixing portion 14.

Further, in the case where the CIS module 60 is disposed on the inner surface 15a as in the present embodiment, even if the maintenance work for the CIS module 60 and the ink injection work for injecting ink into the liquid storage container 70 are simultaneously performed, the inner surface 15a of the scanner cover 15 is less likely to be contaminated with ink. As a result, the contact glass 61 disposed on the inner surface 15a of the scanner cover 15 is not contaminated by ink, and the CIS module 60 can appropriately read the image of the document medium M.

In the present embodiment, in a state where the liquid container 70 is attached to the frame portion 12, the nipping position at which the document medium M is nipped by the second roller pair 56 is arranged on the left side with respect to the inlet 71 of the liquid container 70 in the X-axis direction, and is located at a position different from the inlet 71 of the liquid container 70. That is, the document medium M held by the second roller pair 56 is disposed away from the inlet 71 of the liquid container 70.

According to such a configuration, even if the ink is replenished into the liquid container 70 in the state where the document medium M is held by the second roller pair 56, the document medium M is disposed so as to be separated from the inlet port 71, and therefore, the ink scattered from the inlet port 71 is less likely to adhere to the document medium M.
