As a result, the deflection correction member 234 applies a force to the FFC 233 in the first direction different from the moving direction of the carriage 232 in response to the movement of the carriage 232.

Here, the force in the first direction may be a force in any direction as long as the deformation of the FFC 233 can be suppressed. The force in the first direction includes, for example, a force in a direction opposite to the moving direction of the carriage 232, in which case the force in the first direction may further include a force in another direction, or another force. It does not have to include directional forces.

The configuration in which the deflection correction member 234 applies a force to the FFC 233 in the first direction different from the moving direction of the carriage 232 in response to the movement of the carriage 232 is, for example, when the carriage 232 moves from left to right. , When the carriage 232 moves from right to left, and may be applied to any one or both.

It may be applied to a part of the range or to the whole range.

In the example of FIG. 5, the carriage 232 is located near the left end of the carriage path. In this state, the deflection correction member 234 is located at a predetermined position on the left side of the right end of the FFC 233 while the FFC 233 extends from the left to the right.
The example of FIG. 6 shows a state in which the carriage 232 is located in the middle between the left end and the right end of the carriage path and in the vicinity of the deflection correction member 234. In this state, the deflection correction member 234 starts to move to the right.

Further, the first carriage mechanism 301, the first carriage 332, the first FFC 333, the first roller 334, the first hole portion 451 and the first movement restricting portion 351 the first elastic member 352, the first rotating portion 353, and the first protruding portion. 411 and the first shaft portion 431 are an example of a carriage mechanism, an example of a carriage, an example of an FFC, an example of a roller, an example of a hole portion, an example of a movement restricting portion, an example of an elastic member, an example of a rotating portion, and a protrusion. It is an example of a part and an example of a shaft part.
Further, the first roller 334 is an example of a bending straightening member.

In the example of FIGS. 8 and 9, the first carriage 332 reciprocates in the main scanning direction corresponding to the left-right direction along the carriage path extending in the left-right direction.
In the example of FIG. 8, the first carriage 332 is located on the left side as compared with the example of FIG. That is, when the first carriage 332 moves from left to right, it shifts from the state shown in FIG. 8 to the state shown in FIG. On the contrary, when the first carriage 332 moves from right to left, it shifts from the state shown in FIG. 9 to the state shown in FIG.

Here, the operation of transporting the paper and the configuration and operation of the writing unit having the head and the first carriage 332 are the same as those of FIGS. 5 to 7.
Further, the shape of the first FFC333 is the same as the example of FIGS. 5 to 7.
One end of the first FFC333 in the longitudinal direction is fixed below the first carriage 332, and the other end of the first FFC333 in the longitudinal direction is fixed to a predetermined portion provided near the middle of the carriage path. The first FFC333 is connected to a control unit or the like (not shown in FIGS. 8 to 13) via the predetermined unit.
The first FFC 333 extends to the left from the first carriage 332, is then inverted to the right, and extends to the predetermined portion.

The first roller 334 is movably arranged on the left side of the predetermined portion in the middle of the carriage path. Then, the first roller 334 comes into contact with the first FFC 333 at a predetermined position while the first FFC 333 extends from the left to the right. By this contact, the first roller 334 gives a force to press the first FFC333 from top to bottom to the extent that the first FFC333 can move, and the first FFC333 is in contact with the left side of the first roller 334. Sometimes it can give drag to the first FFC333.
Further, the first roller 334 is configured to move from left to right in response to the movement of the first carriage 332 when the first carriage 332 moves from left to right. That is, the predetermined position where the first roller 334 applies a force to the first FFC 333 moves in accordance with the movement of the first carriage 332.
As a result, the first roller 334 applies a force to the first FFC 333 in the first direction different from the moving direction of the first carriage 332 in response to the movement of the first carriage 332.

Here, the force in the first direction may be a force in any direction as long as the deformation of the first FFC333 can be suppressed. The force in the first direction includes, for example, a force in a direction opposite to the moving direction of the first carriage 332, and in this case, the force in the first direction may further include a force in another direction, or It does not have to include forces in other directions.

The first roller 334 is arranged so as not to come into contact with the first carriage 332 when the first carriage 332 moves, and is provided so as to be able to move the corresponding path in the middle of the carriage path.
The first roller 334 has a first shaft portion 431. The first roller 334 can rotate and move within a range in the left-right direction corresponding to a part of the range of the carriage path in the left-right direction with the first shaft portion 431 as the central axis.

The first movement restricting unit 351 restricts the movement of the first roller 334 to a range in the left-right direction corresponding to a part of the range of the carriage path.
Specifically, the first movement restricting unit 351 has a shape that surrounds the front side and the rear side of the first roller 334. The first movement restricting portion 351 is provided with a first hole portion 451 arranged so as to face each of the front side and the rear side with respect to the first roller 334. The first hole portion 451 is arranged along a range in the left-right direction corresponding to a part of the range of the carriage path, and is arranged on the left side of a predetermined portion to which the first FFC 333 is fixed.
Both ends of the first shaft portion 431 of the first roller 334 are passed through the first hole portion 451 of the first movement restricting portion 351. As a result, the first roller 334 can move along the carriage path within the range of the first hole portion 451 of the first movement restricting portion 351.
The first movement control unit 351 may be called, for example, a holder or the like.

A first rotating portion 353 is provided on the front side with respect to the first roller 334 and the first movement restricting portion 351.
The first rotating portion 353 has a shape similar to an L-shape, and hereinafter, for convenience of explanation, this shape will be referred to as an L-shape.
A hole is provided in the L-shaped bent portion of the first rotating portion 353. Then, the first shaft portion 431 of the first roller 334 is passed through the hole. As a result, the first rotating portion 353 moves left and right together with the first roller 334 when the first roller 334 moves left and right.

A first protrusion 411 is provided on the front side of the first carriage 332. The shape of the first projecting portion 411 may be arbitrary, and may be, for example, a rod shape projecting to the front side of the first carriage 332.
When the first carriage 332 moves from left to right, the first protruding portion 411 collides with one of the two L-shaped sides of the first rotating portion 353 from the left side, and vice versa. When the first carriage 332 moves from right to left, it is arranged so as to collide with the other side of the two L-shaped sides of the first rotating portion 353 from the right side.
The first protruding portion 411 may be referred to as, for example, a protruding portion or the like.

When the first rotating portion 353 is located at the left end within the range of the first hole portion 451 in the left-right direction of the first movement restricting portion 351, one side of the two L-shaped sides of the first rotating portion 353. Is arranged to extend in the vertical direction, and the other side is arranged to extend in the left-right direction on the left side of one side. Then, the first carriage 332 moves from left to right, and the first protruding portion 411 of the first carriage 332 collides with the first rotating portion 353, so that the first rotating portion 353 rotates in the clockwise direction. .. As a result, when the first rotating portion 353 rotates 90 ° clockwise, one of the two L-shaped sides of the first rotating portion 353 extends in the left-right direction, and is left side of the other side. The other side is arranged to extend in the vertical direction. Further, at this time, the first rotating portion 353 is moved to the right end.

When the first rotating portion 353 is located at the right end within the range of the first hole portion 451 in the left-right direction of the first movement restricting portion 351, the first carriage 332 moves from right to left, and the first carriage 332 is the first. When the 1 protruding portion 411 collides with the first rotating portion 353, the first rotating portion 353 rotates in the counterclockwise direction. As a result, when the first rotating portion 353 rotates 90 ° counterclockwise, one side of the two L-shaped sides of the first rotating portion 353 extends in the vertical direction, and the left side of the one side. The other side is arranged to extend in the left-right direction. Further, at this time, the first rotating portion 353 is moved to the left end.

In this way, the first roller 334 and the first rotating portion 353 are moved in the left-right direction within the range of the first hole portion 451 in the left-right direction of the first movement restricting portion 351. Further, the first roller 334 and the first rotating portion 353 are in the same posture when they are in the same position within the range of the first hole portion 451 in the left-right direction of the first movement restricting portion 351.

Further, one end of the first elastic member 352 is fixed near the tip of one of the two L-shaped sides of the first rotating portion 353. Further, the other end of the first elastic member 352 is connected to the vicinity of the center in the left-right direction of the first movement restricting portion 351 and below the first hole portion 451. As a result, the first elastic member 352 applies a drag force to the rotation of the first rotating portion 353.
Further, the first elastic member 352 rotates with the rotation of the first rotating portion 353 as a fulcrum at the connection point with the first movement restricting portion 351 by applying a force exceeding the drag force. That is, the first elastic member 352 rotates clockwise when the first rotating portion 353 rotates clockwise, and rotates counterclockwise when the first rotating portion 353 rotates counterclockwise.

Here, in the present embodiment, the first elastic member 352 is a twisted spring, but as another configuration example, it may be another type of spring.
In the present embodiment, the position of the first roller 334 is regulated by the first movement restricting portion 351 while the first roller 334 is urged by the first elastic member 352 which is a twisting spring via the first rotating portion 353. .. In the present embodiment, the first elastic member 352, which is a twisted spring, has a two-stable configuration.

In the example of FIG. 8, the first carriage 332 is located near the left end of the first hole portion 451 in the left-right direction of the first movement restricting portion 351. In this state, the first roller 334 is located at a predetermined position on the left side of the right end of the first FFC333 while the first FFC333 extends from the left to the right.
In the example of FIG. 9, the first carriage 332 is located near the right end of the carriage path. In this state, the first roller 334 is located near the right end of the first FFC333 while the first FFC333 extends from left to right.

Further, in a state where the first carriage 332 is located at the first moving end 491 on the left side of the carriage path, the first carriage 332 may not necessarily be in contact with the first moving end 491 on the left side of the carriage path. That is, in the present embodiment, when the first carriage 332 is located at the first moving end 491 on the left side of the carriage path, the first carriage 332 is located at the left end of the carriage path, but it is not necessarily physically the first carriage 332. And the first moving end 491 on the left side of the carriage path may not be in contact with each other.

FIG. 10 shows a state in which the first carriage 332 is located at the position of the first moving end 491 on the left side of the carriage path.

Here, the operation of transporting the paper and the configuration and operation of the writing unit having the head and the second carriage 632 are the same as those of FIGS. 5 to 7.
Further, the shape of the second FFC633 is the same as the example of FIGS. 5 to 7.
One end in the longitudinal direction of the second FFC 633 is fixed below the second carriage 632, and the other end in the longitudinal direction of the second FFC 633 is fixed to a predetermined portion provided near the middle of the carriage path. The second FFC633 is connected to a control unit or the like (not shown in FIGS. 14 to 17) via the predetermined unit.
The second FFC 633 extends to the left from the second carriage 632, is then inverted to the right, and extends to the predetermined portion.

The second roller 634 is movably arranged on the left side of the predetermined portion in the middle of the carriage path. Then, the second roller 634 comes into contact with the second FFC 633 at a predetermined position while the second FFC 633 extends from the left to the right. By this contact, the second roller 634, for example, gives a force to press the second FFC 633 from top to bottom to the extent that the second FFC 633 can move, and the second FFC 633 is in contact with the left side of the second roller 634. Sometimes it can give drag to the second FFC633.

Both ends of the second shaft portion 731 of the second roller 634 are passed through the second hole portion 751 of the second movement restricting portion 651. As a result, the second roller 634 can move along the carriage path within the range of the second hole portion 751 of the second movement restricting portion 651.
The second movement control unit 651 may be called, for example, a holder or the like.

The second elastic member 652 is provided on the front side with respect to the second movement restricting portion 651.
The left end of the second elastic member 652 is fixed to a second connecting portion 692 provided at the second moving end 691 on the left side of the carriage path.
The second connecting portion 692 may be, for example, a frame, and the second elastic member 652 and the second connecting portion 692 are fixed by hooking the left end portion of the second elastic member 652 on the frame. May be good.
Here, the second moving end 691 and the second connecting portion 692 are an example of the moving end and an example of the connecting portion, respectively.

The right end of the second elastic member 652 is fixed to the second shaft portion 731 of the second roller 634. In the present embodiment, the second elastic member 652 and the second roller 634 are fixed by hooking the right end portion of the second elastic member 652 on the second shaft portion 731 of the second roller 634.
Specifically, the right end of the second elastic member 652 has a hooking portion formed so as to extend to the left in a U shape after extending to the right. Further, the second shaft portion 731 of the second roller 634 projects to the front side of the second movement restricting portion 651. Then, the second elastic member 652 and the second roller 634 are fixed by hooking the hooked portion on the right side of the second elastic member 652 to the second shaft portion 731 of the second roller 634.
Any method may be used as a method for fixing the second elastic member 652 and the second roller 634.

The second elastic member 652 applies a force for pulling the second roller 634 toward the left side to the second shaft portion 731 of the second roller 634.
In the present embodiment, the second elastic member 652 is a tension spring, but as another configuration example, it may be another type of spring. In the present embodiment, the position of the second roller 634 is regulated by the second movement restricting unit 651, while the second roller 634 is urged by the second elastic member 652 which is a tension spring.

In the example of FIG. 14, the second carriage 632 is located near the left end of the second hole portion 751 in the left-right direction of the second movement restricting portion 651. In this state, the second roller 634 is located at a predetermined position on the left side of the right end of the second FFC 633 while the second FFC 633 extends from the left to the right. In the example of FIG. 14, the predetermined portion is the left end portion of the second hole portion 751 in the left-right direction of the second movement restricting portion 651.
In the example of FIG. 15, the second carriage 632 is located near the right end of the carriage path. In this state, the second roller 634 is located near the right end of the second FFC 633 while the second FFC 633 extends from left to right.

Here, in the transition from the state shown in FIG. 14 to the state shown in FIG. 15, the second carriage 632 moves from left to right, and the second FFC 633 collides with the left side of the second roller 634. The 2FFC633 applies a force to the right side of the second roller 634, and the second roller 634 is moved to the right side. Here, the force applied to the second roller 634 by the second FFC 633 to the right is larger than the force applied to the second roller 634 by the second elastic member 652.

Further, in the transition from the state shown in FIG. 15 to the state shown in FIG. 14, the second carriage 632 moves from right to left, and the second FFC 633 applies a force to the right side to the second roller 634. It will be released. In this case, the second roller 634 moves to the left side until the second FFC 633 moves from the right end to the left end of the second hole portion 751 in the left-right direction of the second movement restricting portion 651 due to the pulling force of the second elastic member 652. Since it is limited by the second FFC633, the position of the second roller 634 is near the position of the second FFC633. After that, when the second FFC 633 moves to the left side of the left end of the second hole portion 751 in the left-right direction of the second movement restricting unit 651, the second FFC 633 separates from the second roller 634 and the second roller 634 is the second movement restricting unit.
