Next, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows an outline of an image forming apparatus 10 that is one of electric devices according to an embodiment of the present invention. The image forming apparatus 10 includes an image forming apparatus main body 12, an image forming unit 14 is mounted in the image forming apparatus main body 12, and a discharge unit 16, which will be described later, is provided above the image forming apparatus main body 12. In addition, for example, a two-stage sheet feeding unit 18 is disposed below the image forming apparatus main body 12. Further, a plurality of paper feeding units can be optionally arranged below the image forming apparatus main body 12.

  Each paper feed unit 18 includes a paper feed unit main body 20 and a paper feed cassette 22 on which a recording medium such as a plurality of sheets can be stacked. A feeding member 24 is disposed in the upper part near the rear end of the sheet feeding cassette 22, and a separating roll 26 and a supply roll 28 are disposed behind the feeding member 24. The supply roll 28 is driven by a drive unit (not shown) and rotates so as to supply the recording medium toward a main conveyance path 32 described later. The separating roll 26 is in pressure contact with the supply roll 28 and is rotatable in accordance with the rotation of the supply roll 28, and supplies the recording medium one by one toward a main conveyance path 32 described later together with the supply roll 28. Rotate like so. For example, when a plurality of recording media are sandwiched between the supply roll 28 and the separating roll 26, the separating roll 26 causes a slip between the stacked recording media, and the recording in which the supply roll 28 is not in contact is performed. The medium is prevented from being conveyed, the recording medium is rolled, and only the uppermost recording medium is sent to the main conveying path 32.

The main conveyance path 32 is a recording medium path from the supply roll 28 to the discharge port 34, and the main conveyance path 32 is on the back side (right side in FIG. 1) of the image forming apparatus main body 12, and the lowermost supply path. A portion formed substantially vertically from the paper unit 18 to a fixing device 36 described later is included. A transfer device 42 and an image holding body 44 which will be described later are arranged on the upstream side of the fixing device 36 in the main transport path 32, and a registration roll 38 is arranged on the upstream side of the transfer device 42 and the image holding body 44. The registration roll 38 temporarily stops the recording medium supplied to the main conveyance path 32 and conveys the recording medium between the transfer device 42 and the image carrier 44 at a predetermined timing.
Further, a discharge roll 40 is disposed in the vicinity of the discharge port 34 of the main conveyance path 32.

  Accordingly, the recording medium fed from the paper feeding cassette 22 of the paper feeding unit 18 by the feeding member 24 is turned by the cooperation of the separating roll 26 and the supply roll 28 and only the uppermost recording medium is guided to the main transport path 32. The developer image is temporarily stopped by the resist roll 38, and a developer image is transferred between a transfer device 42 and an image holding member 44, which will be described later, and the transferred developer image is fixed by the fixing device 36. The paper is discharged from the discharge port 34 to the discharge unit 16 by the discharge roll 40.

  However, in the case of duplex printing, it is returned to the reverse path. That is, the front side of the discharge roll 40 in the main conveyance path 32 is divided into two forks, a switching device 46 is provided in the divided part, and a reverse path 48 is formed from the divided part to the registration roll 38. . The reversing path 48 is provided with transport rolls 50a to 50c. In the case of double-sided printing, the switching device 46 is switched to the side that opens the reversing path 48, and the discharge roll 40 is in front of the rear end of the recording medium. At that time, the discharge roll 40 is reversed, the recording medium is guided to the reverse path 48, and is discharged from the discharge port 34 to the discharge unit 16 through the registration roll 38, the transfer device 42, the image holding body 44 and the fixing device 36. It is.
