There is. When a conductor is wound around a cylindrical ferrite core, it is difficult to stabilize the winding position of the conductor.

Therefore, when arranging another conductor (second conductor) in the vicinity of the conductor (first conductor) wound around the ferrite core, it is necessary to keep the distance between the ferrite core and the second conductor. This is to prevent the first conductor and the ferrite core from coming into contact with the second conductor regardless of the winding position of the first conductor on the ferrite core. However, increasing the distance between the ferrite core and the second conductor causes an increase in the size of the device.

In view of the above problems, the present invention protects the first conductor and the ferrite core without separating the ferrite core around which the first conductor is wound from the second conductor, and protects the first conductor and the ferrite core. It is an object of the present invention to provide a structure capable of preventing contact between the conductor and the second conductor.

The present invention is a conductor holding unit that holds a first conductor and a second conductor, and has a first guide member that guides the first conductor and a second guide member that guides the second conductor. The first guide member is composed of a guide member, and the first guide member has a storage portion for accommodating a ferrite core around which the first conducting wire is wound, and the second guide member is a closing portion that closes the storage portion. The conductor holding unit is characterized in that the first conductor, the ferrite core, and the second conductor are partitioned by the closing portion so as not to come into contact with each other.

According to the present invention, the first conductor, the ferrite core, and the second conductor can be provided while protecting the first conductor and the ferrite core without separating the ferrite core around which the first conductor is wound and the second conductor. It becomes possible to prevent the contact of.

The recording medium sent to the recording unit 5 is held on the platen 51, and an image is recorded by ejecting ink from the recording head 52. The recording head 52 is detachably attached to the carriage 53. The carriage 53 is movably supported by the chassis 54 in the main scanning direction (arrow B direction) intersecting (in this example, orthogonal) with the seat transport direction (arrow A direction). The driving force generated by the carriage drive motor (hereinafter referred to as CR motor) 55 is transmitted to the carriage 53 by a transmission belt (not shown), so that the carriage 53 is reciprocated in the main scanning direction. The recording operation in which the recording head 52 is ejected while moving in the main scanning direction (arrow B direction) together with the carriage 53 and the conveying operation in which a predetermined amount of the recording medium is conveyed in the sub scanning direction (arrow A direction) are repeatedly performed. The image is recorded on the recording medium.

The recording medium on which the image is recorded is sent to the discharge unit 4, and is discharged to the outside of the recording device 1 by the roller 41 and the spur 42. A maintenance unit 6 is provided on one end side of the moving region of the carriage 53 to restore the ink ejection performance of the recording head 52 by cleaning the ink ejection portion. The maintenance unit 6 also has a cap mechanism for capping the surface on which the ink ejection units of the recording head 52 are arranged.

The recording medium is supplied and the maintenance unit 6 is driven by a motor (hereinafter referred to as an AP motor) 24 shared with the maintenance unit 6 provided in the supply unit 2. The transport unit 3 and the discharge unit 4 are driven by a line feed motor (hereinafter referred to as an LF motor) 33.

<About the conductor holding unit>
5 to 7 are explanatory views of a conductor holding unit that holds a plurality of conductors, specifically, an AP motor driving conductor 25 and an AP motor control signal wire 26. Specifically, FIG. 5 is a cross-sectional view of the conductor holding unit, FIG. 6 is a perspective view of the conductor holding unit, and FIG. 7 is an exploded perspective view of the conductor holding unit. As shown in FIGS. 5 to 7, the conductor holding unit includes a first guide member 28 that guides the AP motor driving conductor 25 and a second guide member 29 that guides the AP motor control signal line 26. It is composed by combining. Further, as shown in FIG. 6, the AP motor driving conductor 25 and the AP motor control signal line 26 are at least connected by the retaining claws provided on the first guide member 28, the second guide member 29, and the like. Some are arranged so that they are almost parallel.

As shown in FIGS. 5 and 7, the AP motor driving conductor 25 is wound around a cylindrical ferrite core 27 for the purpose of noise suppression. The ferrite core 27 is housed in a box-shaped (pocket-shaped) core storage portion 281 provided in the first guide member 28 and having an open upper portion. As shown in FIGS. 5 and 6, when the first guide member 28 and the second guide member 29 are combined, the open upper portion of the core storage portion 281 is a cover portion provided on the second guide member 29. It is closed by 291 (also called a closed portion). As a result, the ferrite core 27 and the AP motor driving conductor 25 wound around the ferrite core 27 are held by the first guide member 28 and the second guide member 29 while being protected from the outside.

As shown in FIG. 6, the AP motor control signal line 26 extending from the relay board in parallel with the AP motor drive lead wire 25 passes over the first guide member 28 and guides through the upper surface of the cover portion 291. And connected to the control unit 7. At this time, the AP motor control signal line 26 and the AP motor drive lead wire 25 and the ferrite core 27 are separated by a cover portion 291 that functions as a partition portion. Therefore, the AP motor control signal line 26 does not come into contact with the AP motor drive lead wire 25 or the ferrite core 27. Therefore, when the AP motor driving conductor 25 is wound around the ferrite core 27, it is not necessary to consider the height of the conductors in the stacking direction and the winding position, so that it is possible to prevent a decrease in work efficiency during assembly.

As shown in FIGS. 6 and 7, the position of the cover portion 291 is positioned by the positioning portion 282 provided on the first guide member 28. Therefore, even when a force is applied to the guide member by the conducting wire or an external force is applied during transportation of the recording device 1, the relative position of the cover portion 291 with respect to the core accommodating portion 281 can be maintained. This reliably protects the ferrite core 27 and the AP motor drive lead wire 25 in the core housing 281 while preventing contact between the ferrite core 27 and the AP motor drive lead wire 25 and the AP motor control signal line 26. It becomes possible to do.

Further, as shown in FIGS. 5 and 7, the AP motor control signal line 26 is guided on the cover portion 291 by the guide portion 292 provided on the second guide member 29. At this time, the guide unit 292 guides the AP motor control signal line 26, which extends substantially in parallel with the AP motor drive lead wire 25, so as to extend in a direction away from the core storage unit 281. As a result, the AP motor control signal line 26 is prevented from entering the core accommodating portion 281 beyond the cover portion 291.
