3 to 8, the power supply wire 13 according to the first embodiment is configured by bending a conductive metal wire. The power supply wire 13 has a power supply connection portion 31. The power supply connection part 31 has a string-like connection coil 31a in which a wire is wound spirally. The connection coil 31a is coupled to a terminal (not shown) of the power supply unit 10. From one end of the connection coil 31a, a lower end portion 31b supported by the lower guide 12a, an oblique portion 31c supported by the support groove 12b2 of the oblique guide portion 12b, a longitudinal lower portion 31d supported by the lower portion of the longitudinal guide 12c, and the longitudinal guide 12c. A vertical upper part 31e supported on the upper part is continuously formed. A fixed arm 31f extending along the support surface 16 is continuously formed at the upper end of the vertical upper portion 31e. The fixed arm 31f is supported by the support surface 16 as shown in FIG. 5B, and is supported by the left stopper wall 23 as shown in FIG. 5C and the like.

A coil spring 32 as an example of a supported portion is provided at the upper end of the fixed arm 31f. That is, one end of the coil spring 32 is connected to the power supply connection portion 31. In addition, the coil spring 32 is formed in a string winding shape in which a wire is wound spirally, and is configured to be elastically deformable. The coil spring 32 is supported in such a manner that the coil support portion 17 fits in the center of the coil. The other end of the coil spring 32 is connected to a power supply coil 34 as an example of a power supply unit via a connection arm 33 as an example of a connection unit extending rearward to the right.
The power supply coil 34 is formed in a string winding shape in which a wire is wound spirally. The power feeding coil 34 is configured to be able to contact the power supplied plate 1. At the other end of the power feeding coil 34, a retaining connection portion 36 as an example of a second connection portion is formed.

(Operation of Example 1)
In the printer U according to the first embodiment having the above-described configuration, when the process unit PU is mounted, the coil spring 32 is elastically deformed and the feeding coil 34 is moved to the right as shown by the solid line in FIGS. 5 and 8B. The feed coil 34 contacts the fed plate 1 with a preset pressure.
When the process unit PU is removed, the power supply coil 34 is separated from the power-supplied plate 1. Therefore, the coil spring 32 is elastically restored, and the stopper 37 comes into contact with the left stopper wall 19 and stops in a state indicated by a broken line in FIGS. 6 and 8B.

  Further, when the upper part of the power supply wire 13 of the first embodiment tries to come out of the wire guide 12 due to vibrations or the like, the stopper 37 is stopped by the upper stopper wall 22 and the feed coil is turned off. 34 is stopped at the buttocks 24. Further, even if the power supply wire 13 is about to come off to the left, the fixed arm 31 f is stopped by the left stopper wall 19. Further, the stopper 37 is stopped at the right stopper wall 19 even if the feeding wire 13 is about to come off to the right. Further, the coil spring 32 and the fixed arm 31 f are stopped at the support surface 16 even if the power supply wire 13 is about to be pulled downward. Therefore, the position difference of the power supply wire 13 of the first embodiment is suppressed with respect to the wire guide 12, and the position of the power supply coil 34 is stabilized. Therefore, the contact between the power supply coil 34 and the power-supplied plate 1 is easily stabilized. Further, the power supply wire 13 according to the first embodiment is prevented from dropping from the wire guide 12.

FIG. 9 is an explanatory view of a power feeding member in the prior art.
In FIG. 9, in the technique described in Patent Document 1, a portion 01 corresponding to the retaining connection portion 36 and the stopper 37 of the first embodiment extends in the rearward direction in the first embodiment. That is, the parts 01 and 03 that are fixed so that the power feeding unit 02 is movable project from the power feeding unit 02 to the front and rear sides. In such a configuration, it is necessary to secure a space corresponding to a movable range and a movable locus in which the protruding portion 01 moves when the power feeding unit 02 contacts and separates from the power supplied unit of the process unit. However, with the recent miniaturization of the image forming apparatus, there are problems that the space for fixing the power supply wire is small or the space corresponding to the movable range cannot be secured.
In contrast, in the first embodiment, the stopper 37 extends toward the coil spring 32. Therefore, compared with the configuration shown in Patent Document 1 and FIG. 9, the space in which the feeding wire 13 is installed can be reduced in size. Therefore, it is possible to contribute to downsizing of the printer U.

Further, in the power supply wire 13 of the first embodiment, the power supply coil 34 is formed in a coil shape. Therefore, the position in contact with the power supplied plate 1 is formed on the curved surface. Therefore, compared with the case where the part of the feeding coil 34 is formed in a sharp shape, the non-feeding coil 34 and the fed plate 1 are reduced from being scraped or worn. Therefore, it is possible to extend the life of the feeder wire 13.
Furthermore, the power supply wire 13 according to the first embodiment is configured by bending one wire. Therefore, compared with the case where a plurality of members are combined or joined, the number of parts is reduced, and manufacturing costs and assembly costs are reduced.

  Further, in the first embodiment, the fixed arm 31f is supported in a state of being in contact with the support surface 16. Therefore, as compared with the case where it floats from the support surface 16, even if the coil spring 32 is elastically deformed and a force acts on the fixed arm 31f, the fixed arm 31f is less likely to swing. Therefore, adverse effects such as the position of the power feeding coil 34 being displaced or the contact pressure fluctuating due to the swinging of the fixed arm 31f and the contact between the power feeding coil 34 and the power supplied plate 1 becoming unstable can be suppressed.
