  • Patent number: 9188946
    Abstract: The image forming apparatus includes an image forming section; a conveyance path to convey a recording medium to the image forming section; a drawer unit including the conveyance path and configured to be pulled out relative to the apparatus; an electrical cable to electrically connect the drawer unit and an interior of the apparatus even when the drawer unit is pulled out from the apparatus; and a cable holder (a first regulating member) to ensure that that the cable is securely prevented from protruding from the drawer unit. According to the present invention, the electric cable is prevented from running off from the drawer unit due to the folding of the cable caused by the regulating member, so that the electric cable is prevented from getting hung up on the parts disposed in the body.

  • Patent number: 9176462
    Abstract: An image forming apparatus having a drawer unit that includes therein a paper-feeding conveying path for conveying a recording medium conveyed from a paper feeding unit on which the recording media are stacked to an image forming unit and/or a discharge conveying path for conveying the recording medium on which an image has been formed to a discharging unit, and be drawn out from an apparatus main body; a lock unit that locks the drawer unit to the apparatus main body; a straddle detecting unit that detects whether the recording medium straddles a conveying path in the apparatus main body and a conveying path in the drawer unit; and a controller that controls the lock unit to lock the drawer unit to the apparatus main body when the straddle detecting unit detects the straddle.
