The two second contact parts 72 are provided, respectively, on the left side and the right side of the casing 11. Since the second contact parts 72 are not present in the vicinity of the center in the left-right direction of the casing 11, and thus in a case that the second contact parts 72 are rotated, the second contact parts 72 do not make contact with the plurality of spur rollers 54, the plurality of discharging rollers 55 and the cutter unit 6.

Two pieces of the rotation shaft 71 are provided on the inside of the casing 11. The two rotation shafts 71 are provided, respectively, on the left side and the right side of the casing 11. The rotation shafts 71 are not present in the vicinity of the center in the left-right direction of the casing 11. In a case that the cover 12 is moved to (positioned at) the first position, the shielding part 70 is arranged at a location above the first contact parts 14.

Accompanying with the first action of the cover 12, the shielding part 70 makes contact with the first contact parts 14 and rotates, and thereby moves from a contact position at which the shielding part 70 is capable of making contact with the first contact parts 14 to a shielding position at which the shielding part 70 shields at least a part of the cutter unit 6 from the outside of the casing 11. In this situation, the second contact parts 72 also rotate accompanying with the rotation of the shielding part 70. Specifically, each of the shielding part 70 and the second contact parts 72 moves from a position thereof depicted in FIGS. 1 and 2 to a position depicted in FIGS. 3 and 4.

The contact position is a position of the shielding part 70 as depicted in FIGS. 1 and 2, and the shielding position is a position of the shielding part 70 as depicted in FIGS. 3 and 4. In a case that the shielding part 70 is positioned at the shielding position, the cover 12 is positioned at the second position, and the shielding part 70 shield at least a part of the cutter unit 6 from the outside of the casing 11. In a case that the cover 12 is positioned at the second position, the shielding part 70 is arranged at the location above the cutter unit 6, and the second contact parts 72 are arranged at the location below the first contact parts 14. As depicted in FIG. 4, for example, the shielding part 70 shields the blades 62 and 63 as seen thereabove and covers the part of the cutter carriage 61.

In the case that the user moves the cover 12 from the first position to the second position and exchanges a cartridge 46, the cartridge 46 is exposed from the opening 15 formed in the casing 11. In this case, there is provided a state that at least the part of the cutter unit 6 is shielded, by the shielding part 70, from the outside of the casing 11.

In the case that the cover 12 is positioned at the second position at which the cover 12 releases the opening 15, the shielding part 70 shields at least the part of the cutter unit 6 from the outside of the casing 11. Accordingly, in the case that the cartridge 46 is to be exchanged, it is possible to prevent, by the shielding part 70, any access to the cutter unit 6. Further, with a simple configuration that the shielding part 70 is arranged to be rotatable in the inside of the casing 11, it is possible to provide the state, in the case that the cover 12 is opened, that the shielding part 70 shields at least the part of the cutter unit 6.

Accompanying with a second action in which the cover 12 is moved from the second position to the first position, the second contact parts 72 make contact with the first contact parts 14 and rotate, thereby causing the shielding part 70 to move from the shielding position to the contact position. Specifically, each of the shielding part 70 and the second contact parts 72 moves from the position thereof depicted in FIGS. 3 and 4 to the position thereof depicted in FIGS. 1 and 2. The second action is an action (operation) by which the cover 12 is closed.

Accompanying with the action by which the cover 12 is closed, the shielding part 70 returns from the shielding position to the contact position. Accordingly, in a case that the cover 12 is opened again, the shielding part 70 moves from the contact position to the shielding position, thereby making it possible to provide the state that the shielding part 70 covers at least the part of the cutter unit 6. Namely, accompanying with the opening/closing action of the cover 12, the shielding part 70 is capable of repeating the movement between the contact position and the shielding position.

As described above, the shielding part 70 moves, accompanying with the first action in which the cover 12 moves from the first position to the second position, so that the shielding part 70 shields at least the part of the cutter unit 6 from the outside of the casing 11.

Accompanying with the first action of the cover 12, the shielding part 70 moves so that the shielding part 70 shields at least the part of the cutter unit 6 from the outside of the casing 11. Accordingly, in a case that the cover 12 is opened, there is provided a state that at least the part of the cutter unit 6 is shielded by the shielding part 70. Therefore, in the case that the cover 12 is opened and the cartridge 46 is to be exchanged, it is possible to prevent, by the shielding part 70, any access to the cutter unit 6.

In this case, a part on the lower side with respect to the opening 15 in the front wall 111 shields at least the part of the cutter unit 6 from the outside of the casing 111. The part on the lower side with respect to the opening 15 in the front wall 111 is a part of the front wall 111 and an example of the shielding part.

Since at least the part of the cutter unit 6 can be shielded by the shielding part which is a part of the front wall 111 of the casing 11, there is no need to newly provide a member configured to shield the cuter unit 6. Accordingly, the manufacturing cost of the ink-jet printer 1 can be reduced.

Fourth Modification

An ink-jet printer 1A according to a fourth modification will be explained, with reference to FIGS. 5 and 6. As compared with the ink-jet printer 1, the ink-jet printer 1A is different from the ink-jet printer 1 in view of a point that the ink-jet printer 1A is not provided with the first contacting parts 14, the spur rollers 54, the discharging rollers 55, the shielding part 70, the rotation shafts 71 and the second contact parts 72.

Further, as compared with the ink-jet printer 1, the ink-jet printer 1A is different from the ink-jet printer 1 in view of a point that the cover 12 is changed to the cover 12A and the cutter unit 6 is changed to a cutter unit 6A.

As depicted in FIG. 6, accompanying with the first action of the cover 12A, the flat parts 121A rotate with respect to the casing 11, and the connecting member 73 rotates with respect to the flat parts 121A. With this, the blade 63 and the cutter supporting pert 64A move so as to fall rearward. By the rotation of the connecting member 73, the relative position of the connecting member 73 with respect to the support shaft 76 is changed.

Further, by the movement of each of the blade 63 and the cutter supporting part 64A, the blade 63 is shielded by the shielding part 70A. The shielding part 70A is provided on the rear side with respect to the discharge tray 22 and extends in the up-down direction. In such a manner, the blade 63 and the cutter supporting part 64A of the cutter unit 6A move, accompanying with the first action in which the cover 12A moves from the first position to the second position, so that the shielding part 70A shields at least the part of the cutter unit 6A from the outside of the casing 11.

Accordingly, in the case that the cover 12A is opened, there is provided a state that at least the part of the cutter unit 6A is shielded by the shielding part 70A. Accordingly, in the case that the cover 12A is opened and the cartridge 46 is to be exchanged, it is possible to prevent, by the shielding part 70A, any access to the cutter unit 6A.

Fifth Modification

An ink-jet printer 1B according to a fifth modification will be explained, with reference to FIGS. 7 to 9.

As depicted in FIGS. 7 to 9, as compared with the ink-jet printer 1, the ink-jet printer 1B is different from the ink-jet printer 1 in view of a point that the ink-jet printer 1B is not provided with the first contacting parts 14, the spur rollers 54, the discharging rollers 55, the shielding part 70, the rotation shafts 71 and the second contact parts 72. Note that in FIGS. 7 to 9, the discharge tray 22 is omitted. As depicted in FIG. 7, an opening 701B is formed (defined) in a shielding part 70B, and in a state that a cover 12B is closed, a sheet P is arranged in the inside of the opening 701B.

Further, as compared with the ink-jet printer 1, the ink-jet printer 1B is different from the ink-jet printer 1 in view of a point that the cover 12 is changed to the cover 12B, and a point that the rotation shaft 13 is changed to a rotation shaft 13A. Further, as compared with the ink-jet printer 1, the ink-jet printer 1B is different from the ink-jet printer 1 in view of a point that the ink-jet printer 1B is provided with the shielding part 70B and gears 131A and 131B.

As depicted in FIG. 8, the shielding part 70B is provided to extend in the left-right direction. Two pieces of the rotation shaft 13A are provided on the inside of the casing 11. The two rotation shafts 13A are provided, respectively, on the left side and the right side of the inside of the casing 11. The rotation shafts 13A are not present in the vicinity of the center in the left-right direction of the casing 11.

Two pieces of the gear 131A are provided on the inside of the casing 11. The two gears 131A are provided, respectively, on the left side and the right side of the inside of the casing 11. The gears 131A are not present in the vicinity of the center in the left-right direction of the casing 11. Two pieces of the gear 132A are provided on the inside of the casing 11. The two gears 132A are provided, respectively, on the left side and the right side of the inside of the casing 11. The gears 132A are not present in the vicinity of the center in the left-right direction of the casing 11.

As depicted in FIG. 9, the rotation shafts 13A rotate accompanying with the first action of the cover 12B, which in turn causes the gears 131A to also rotate accompanying with the rotation of the rotation shafts 13A, thereby causing the gears 132A to also rotate accompanying with the rotation of the gears 131A. With this, the shielding part 70B moves upward accompanying with the rotation of the gears 132A, while making contact with the gears 132A. By the upward movement of the shielding part 70B, the blades 62 and 63 and the cutter supporting part 64 are shielded by the shielding part 70B.

In a case that the shielding part 70B moves upward, the shielding part 70B passes through an opening 221 formed in the discharge tray 22 and moves up to a position at which the shielding part 70B shields the blades 62 and 63 and the cutter supporting part 64. In this case, a hatched part in the shielding part 70B is inserted into the opening 221.

Sixth Modification

An ink-jet printer 1C according to a sixth modification will be explained, with reference to FIGS. 10A to 10C.

As compared with the ink-jet printer 1, an ink-jet printer according to the sixth modification is different from the ink-jet printer 1 in view of a point that the ink-jet printer is not provided with the first contacting parts 14, the shielding part 70, the rotation shafts 71 and the second contact parts 72. Further, as compared with the ink-jet printer 1, the ink-jet printer according to the sixth modification is different from the ink jet printer 1 in view of a point that the cutter unit 6 is changed to a cutter unit 6B and a point that the ink-jet printer is provided with a shielding part 70C.

As depicted in FIG. 10A, the cutter unit 6B is provided with a cutter carriage 611, blades 62B and 63B, a supporting member 65B and an electric motor 66B. The cutter carriage 611 is constructed of an upper part 61B and a lower part 64B. The upper part 61B rotatably supports the blade 62B, and the lower part 64B rotatably supports the blade 63B. Each of the blades 62B and 63B is, for example, a round blade. The supporting member 65B is a member configured to movably support the cutter carriage 611 and is provided to extend in the left-right direction.

The cutter unit 6B has an endless driving belt (not depicted in the drawings) which is wound around non-illustrated two pulleys. The cutter carriage 611 is connected to the driving belt. One of the two pulleys is connected to the electric motor 66B. In a case that the electric motor 66B is driven, the pulley connected to the electric motor 66B is thereby rotated, which in turn rotates also the driving belt. With this, the cutter carriage 611 reciprocally moves in the left-right direction along the supporting member 65B, thereby allowing the cutter unit 6B to cut the sheet P with the blades 62B and 63B.

A recessed part 611B is formed, in a surface on the front side in the upper part 61B, so that the recessed part 611B extends in the left-right direction. As depicted in FIG. 10C, a projected part 701C provided on a surface on the rear side in the shielding part 70C fits into the recessed part 611B such that the projected part 701C is caught in the recessed part 611B.

A projected part 703C and a projected part 73C are formed in a surface on the front side in the shielding part 70C. A projected part 702C and an electric actuator 71C are provided on a surface on the front side in the upper part 61B. The projected part 702C and the projected part 703C are connected via an elastic member 72C. The elastic member 72C is, for example, a spring or rubber.

The ink-jet printer according to the sixth modification is provided with a non-illustrated cover sensor which is attached to an inner wall of the casing 11 and which is configured to detect opening and closing of the cover 12. In a case that the cover sensor detects that the cover 12 is opened, the electric actuator 71C moves the projected part 74C rightward, thereby causing the projected part 73C to move rightward while causing the projected part 74C to make contact with the projected part 73C. With this, the shielding part 70C moves rightward and at least a part of each of the blades 62C and 63B is shielded by the shielding part 70C.

Further, in a case that the cover sensor detects that the cover 12 is closed, the electric actuator 71C moves the projected part 74C leftward. With this, the elastic member 72C is contracted to thereby pulls the projected part 703C to approach closer to the projected part 702C, which in turn causes the shielding part 70C to move leftward and to return to an original position.

Note that the electric actuator 71C may be provided on the supporting member 65B. In this case, in a case that the cutter carriage 611 is at a standby position, the electric actuator 71C is capable of causing the projected part 74C to make contact with the projected part 73C. The standby position is a position at which the sheet P has not reached the cutter unit 6B yet, or a position at which the cutter unit 6B stands by in a case that cutting of the sheet P by the cutter unit 6B has completed.

Second Embodiment

A second embodiment of the present disclosure will be explained below, with reference to FIG. 11. Note that for the sake of convenience of explanation, same reference numerals are affixed to members, of the second embodiment, which have the same functions as those of the members explained in the first embodiment, and the explanation therefor will not be repeated.

The scanner unit 16 is provided on the upper wall 112 of the casing 11A. The scanner unit 16 is provided to be movable to a first position at which the scanner unit 16 covers the opening 15B, and to a second position at which the scanner unit 16 releases or opens the opening 15B. Specifically, the scanner unit 16 is provided to be rotatable with respect to the upper wall 112 via the rotation shaft 17. The scanner unit 16 is an example of the “opening/closing part”. Note that it is allowable that the cover 12 depicted in FIG. 1 is provided on the upper wall 112, rather than the scanner unit 16.

The opening 15B is formed at a position at which the opening 15B is capable of releasing a location above the installment part 44A in a case that the scanner unit 16 is at the second position. The scanner unit 16 reads an image printed on a manuscript (original) placed on a light transmittable (optically transparent) member such as a glass plate, etc., by a reading part which is, for example, a CIS (Contact Image Sensor), etc., and converts the read image into image data.

As compared with the printing part 4, the printing part 4A is different from the printing part 4 in view of a point that the head carriage 40 is changed to a head carriage 40A, a point that the installment part 44 is changed to an installment part 44A and a point that the printing part 4A is provided with a liquid discharging head 41. In a case that a driving force of a non-illustrated head carriage motor is transmitted to the head carriage 40A, the head carriage 40A moves reciprocally in the left-right direction along the supporting frame 80A. The supporting frame 80A is provided to extend in the left-right direction and movably supports the head carriage 40A. Two pieces of the supporting frame 80 are provided.

The installment part 44A is provided on the upper side with respect to the head carriage 40A. The installment part 44A is a part which is between the head carriage 40A and the cartridge 46A in a case that the cartridge 46A is installed in the installment part 44A. The cartridge 46A is installable in the installment part 44A from the opening 15B.

The cartridge 46A is configured to be used in a printing by the printing part 4A. The cartridge 46A has a liquid storing part 45A. The liquid discharging head 41 is provided on the head carriage 40A.

Note that it is allowable that the liquid discharging head 41 is provided on the cartridge 46A. In this case, the printing part 4 does not have the liquid discharging head 41. Further, the cartridge 46A may be a cartridge in which a cartridge body having the liquid storing part 45A and the liquid discharging head 41 are integrally formed, or the cartridge 46A may be a cartridge wherein the liquid discharging head 41 is a separate body and separable with respect to the cartridge body.

The holder 70D is an example of the “shielding part” and holds spur rollers 52 and 54. A recessed part 71D is formed in a lower surface of the holder 70D, and a cutter carriage 61 is arranged in a space surrounded by the recessed part 71D. The spur rollers 52 and 54 are each an example of a “guide member” which guides, in the conveying direction R1, a sheet P having an image recorded thereon by the printing part 4A.

Further, the holder 70D shields at least a part of the cutter unit 6 from the outside of the casing 11A. For example, the holder 70D may cover a location above the cutter unit 6. The holder 70D provides both of a function of holding the spur rollers 52 and 54 and a function of shielding at least the part of the cutter unit 6 from the outside of the casing 11A.

It is possible to shield at least the part of the cutter unit 6 by the holder 70D configured to hold the spur rollers 52 and 54 which guide the sheet P to the conveying direction R1, and thus there is no need to newly provide a member configured to shield the cutter unit 6. Accordingly, the manufacturing cost of the ink-jet printer 1C can be reduced.

By normal rotation of each of the spur rollers 54 and the discharging rollers 55, the sheet P is discharged to the discharge tray 22, while being pinched or held by the spur rollers 54 and the discharging rollers 55. In this situation, the sheet P is discharged to the discharge tray 22 from an opening 15C formed in a front wall 111 of the casing 11A.

Seventh Modification

An ink-jet printer 1D according to a seventh modification of the present disclosure will be explained, with reference to FIG. 12. As depicted in FIG. 12, as compared with the ink-jet printer 1C, the ink-jet printer 1D is different from the ink-jet printer 1C in view of a point that among the two supporting frames 80A, a supporting frame 80A on the front side is changed to a supporting frame 70E, and a point that the ink-jet printer 1D is not provided with the holder 70D.

The supporting frame 70E extends in the front-rear direction to a great extent, as compared with the supporting frame 80A, and shields at least a part of the cutter unit 6 from the outside of the casing 11A. The supporting frame 70E is an example of the “shielding part”. The supporting frame 70E may cover a location above the cutter unit 6. The supporting frame 70E is provided to extend in the left-right direction, and movably supports a head carriage 40A.

Since at least the part of the cutter unit 6 can be shielded by the supporting frame 70E which movably supports the head carriage 40A, there is no need to newly provided a member configured to shield the cuter unit 6. Accordingly, the manufacturing cost of the ink-jet printer 1D can be reduced.

Eighth Modification

An ink-jet printer 1E according to an eighth modification of the present disclosure will be explained, with reference to FIGS. 13 and 14. Note that in FIG. 14, the discharge tray 22 is omitted. As depicted in FIG. 13, as compared with the ink-jet printer 1C, the ink-jet printer 1E is different from the ink-jet printer 1C in view of a point that the ink-jet printer 1E is not provided with the holder 70D and that the ink-jet printer 1E is provided with a partitioning part 70F.

The ink-jet printer 1E is provided with a connecting part 71F, a wiring 72F and a substrate 73F. The substrate 73F is configured to control the liquid discharging head 41 of the printing part 4 and is provided on the partitioning part 70F. The substrate 73F is electrically connected to the connecting part 71F by the wiring 72F.

The connecting part 71F is provided on a head carriage 40A, and electrically connects the wiring 72 and a liquid discharging head 41. The wiring 72F electrically connects the liquid discharging head 41 and the substrate 73. The wiring 72F is, for example, a flexible wiring such as a FPC (Flexible Printed Circuit), etc. As depicted in FIG. 14, the wiring 72F extends leftward from the substrate 73F, is folded back rightward at an intermediate location of the wiring 72F and is connected to the connecting part 71F.

The partitioning part 70F is configured to partition the wiring 72F and the cutter unit 6 from each other, and is an example of the “shielding part”. The partitioning part 70F is provided to extend in the front-rear direction and the left-right direction. The partitioning part 70F shields at least a part of the cutter unit 6 from the outside of the casing 11A. For example, the partitioning part 70F may cover a location above the cutter unit 6. Further, the partitioning part 70F supports the wiring 72.

It is possible to shield at least the part of the cutter unit 6 by the partitioning part 70F which partitions the cutter unit 6 from the wiring 72 electrically connecting the printing part 4A and the substrate 73F. Accordingly, there is no need to newly provide a member configured to shield the cutter unit 6. Thus, the manufacturing cost of the ink-jet printer 1E can be reduced. Further, since the partitioning part 70F supports the wiring 72F, the partitioning part 70F is capable of providing both of a function of partitioning the wiring 72F and the cutter unit 6 from each other and a function of supporting the wiring 72F.

Ninth Modification

An ink-jet printer 1F according to a ninth modification of the present disclosure will be explained, with reference to FIG. 15. As depicted in FIG. 15, as compared with the ink-jet printer 1C, the ink-jet printer 1F is different from the ink-jet printer 1C in view of a point that the ink-jet printer 1F is not provided with the holder 70D, a point that the casing 11A is changed to a casing 11B and a point that the ink-jet printer 1F is provided with a shielding part 70G.

As compared with the casing 11A, the casing 11B is different from the casing 11A in view of a point that an opening 15D, which is smaller than the opening 15B, is formed in the casing 11B. The opening 15D is formed at a location above the installment part 44A and in an upper wall 112 of the casing 11B. In a case that a shielding part 70F2, which is a part of the upper wall 112 of the casing 11B, is located at a second position at which the shielding part 70F2 releases the opening 15D of a scanner unit 16, the shielding part 70F2 shields at least a part of the cutter unit 6 from the outside of the casing 11B.

Since it is possible to shield at least the part of the cutter unit 6 by the shielding part 70F2 which is the part of the upper wall 112 of the casing 11B, there is no need to newly provide a member configured to shield the cuter unit 6. Accordingly, the manufacturing cost of the ink-jet printer 1F can be reduced.

Further, the shielding part 70G is provided on the shielding part 70F2 such that the shielding part 70G extends downward from an end part on the rear side in the shielding part 70F2. The shielding part 70G also shields at least the part of the cutter unit 6 from the outside of the casing 11B. Accordingly, in a case that the scanner unit 16 is opened and that the cartridge 46A is (to be) exchanged, it is possible to prevent any access to the cutter unit 6 by the shielding part 70G.

Tenth Modification

An ink-jet printer 1G according to a tenth modification of the present disclosure will be explained, with reference to FIG. 16.

As compared with the printing part 4A, the printing part 4B is different from the printing part 4A in view of a point that the head carriage 40 is changed to a head carriage 70H. A driving force of a non-illustrated head carriage motor is transmitted to the head carriage 70H, thereby causing the head carriage 70H to move reciprocally in the left-right direction along the supporting frames 80B, 80C and 80D.

A recessed part 71H is formed in a lower surface of the head carriage 70H, and at least a part of a cutter carriage 61 is arranged in a space surrounded by the recessed part 71H. The head carriage 70H holds a liquid discharging head 41. The supporting frames 80B and 80D movably support the head carriage 70H. The supporting frame 80C is provided on the holder 56 and supports the holder 56. The supporting frame 80D is provided on the holder 57. The holder 57 holds a plurality of spur rollers 54.

The cutter unit 6 is arranged at a location below the head carriage 70H. By arranging the cutter unit 6 at the location below the head carriage 70H, it is possible to make the size in a horizontal direction of the ink-jet printing 1G to be small, as compared with a case that the cutter unit 6 and the head carriage 70H do not overlap with each other in the up-down direction.

Further, the head carriage 70H is an example of the “shielding part” which shields at least the part of the cutter unit 6 from the outside of the casing 11A, by covering a location above the cutter unit 6. By arranging the head carriage 70H at the location above the cutter unit 6, it is possible to shield the cutter unit 6 by the head carriage 70H. Thus, there is no need to newly provide a member configured to shield the cuter unit 6. Accordingly, the manufacturing cost of the ink-jet printer 1G can be reduced.

Since at least the part of the processing unit can be shielded by the holder configured to hold the guide member which guides the printing medium to the conveying direction, there is no need to newly provide a member configured to shield the processing unit. Accordingly, the manufacturing cost of the printing apparatus can be reduced.

In the printing apparatus according to the aspect of the present disclosure, it is allowable that the printing part is provided with a head carriage configured to hold a liquid discharging head having a nozzle from which a liquid is discharged; and that the shielding part is a supporting frame configured to movably support the head carriage. Since at least the part of the processing unit can be shielded by the supporting frame configured to movably support the head carriage, there is no need to newly provide a member configured to shield the processing unit. Accordingly, the manufacturing cost of the printing apparatus can be reduced.

The printing apparatus according to the aspect of the present disclosure may further include a substrate configured to control the printing part; it is allowable that the shielding part is a partitioning part configured to partition the processing unit from a wiring electrically connecting the printing part and the substrate. It is possible to shield at least the part of the processing unit by the partitioning part configured to partition the processing unit from the wiring electrically connecting the printing part and the substrate. Accordingly, there is no need to newly provide a member configured to shield the processing unit. Accordingly, the manufacturing cost of the printing apparatus can be reduced.

In the printing apparatus according to the aspect of the present disclosure, it is allowable that the partitioning part is configured to support the wiring. Since the partitioning part supports the wiring, the partitioning part is capable of providing both of a function of partitioning the wiring and the processing unit from each other and the function of supporting the wiring.

In the printing apparatus according to the aspect of the present disclosure, it is allowable that the opening is defined at a position at which the opening is capable of releasing, to the outside of the casing, the part of the installment part on the downstream side in the conveying direction and in a front wall on the downstream side in conveying direction of the casing; and that the shielding part is a part of the front wall on the downstream side in conveying direction of the casing. Since at least the part of the processing unit can be shielded by the part of the front wall of the casing, there is no need to newly provide a member configured to shield the processing unit. Accordingly, the manufacturing cost of the printing apparatus can be reduced.

In the printing apparatus according to the aspect of the present disclosure, it is allowable that the opening is defined at the location above the installment part and in an upper wall of the casing; and that the shielding part is a part of the upper wall of the casing. Since it is possible to shield at least the part of the processing unit by the part of the upper wall of the casing, there is no need to newly provide a member configured to shield the processing unit. Accordingly, the manufacturing cost of the printing apparatus can be reduced.

In the printing apparatus according to the aspect of the present disclosure, it is allowable that the printing part is provided with a head carriage configured to hold a liquid discharging head having a nozzle from which a liquid is discharged; and that the processing unit is arranged at a location below the head carriage. By arranging the processing unit at the location below the head carriage, it is possible to make the size, in a horizontal direction, of the printing apparatus to be small, as compared with a case wherein the processing unit and the head carriage do not overlap with each other in the up-down direction.

In the printing apparatus according to the aspect of the present disclosure, it is allowable that the shielding part is the head carriage configured to cover a location above the processing unit. By arranging the processing unit at the location above the processing unit, it is possible to shield at least a part of the processing unit by the head carriage. Thus, there is no need to newly provide a member configured to shield the processing unit. Accordingly, the manufacturing cost of the printing apparatus can be reduced.
