A drive unit includes a drive source and a driving force transmitter that includes a plurality of rotators, an endless belt stretched by the plurality of rotators, a pressing member to press the endless belt, a first support shaft, a first link member to hold the pressing member, a second support shaft, a second link member to press the first link member, a biasing member to bias the second link member. A relation of L1 to L2 satisfies L1>L2, where L1 denotes a distance between the second support shaft and a biasing position and L2 denotes a distance between the second support shaft and a first pressing position. A relation of L3 to L4 satisfies L3>L4, where L3 denotes a distance between the first support shaft and the pressing position and L4 denotes a distance between the first support shaft and a second pressing position.

In one example, a conveyance module to advance a belt toward a print station comprises a support structure to support a belt and to permit advance of the belt in a belt-advance direction toward a print station and a pair of guides. In this example, each guide is attached to the support structure and is to engage a portion of a belt. A first guide in the pair is attached to the support structure by a substantially rigid fastener to hold the first guide in a substantially fixed position relative to the support structure. A second guide in the pair is attached to the support structure by a resiliently deformable element to hold the second guide in a movable position relative to the support structure.

A feeding portion includes a pickup member and a feeding member. A first sheet sensor that is arranged on an upstream side in a sheet conveyance direction with respect to a conveying member, detects a sheet conveyed along a conveyance path. A second sheet sensor detects the sheet at a position between the pickup member and the feeding member. A control portion causes the feeding portion to start feeding of a subsequent sheet when the subsequent sheet is detected by the second sheet sensor at a first timing after detection of a preceding sheet by the first sheet sensor. Furthermore, the control portion causes the feeding portion to start feeding of the subsequent sheet at a second timing later than the first timing, when the subsequent sheet is detected by the second sheet sensor at the first timing.

A belt driving device includes: an endless belt; a stretch roller to engage the endless belt, the stretch roller including a rotary shaft; a steering roller spaced apart from the stretch roller within the endless belt; an adjustment member located along the rotary shaft of the stretch roller, the adjustment member movable along the rotary shaft; and linking mechanism to couple the adjustment member to the steering roller, the linking mechanism to engage a contact surface of the adjustment member. The contact surface includes contact points positioned at different distances from the rotary shaft to raise the linking mechanism during movement of the adjustment member, to cause the steering roller to tilt at an angle, and to maintain an alignment of the endless belt.

A sheet conveying apparatus for conveying a sheet in a conveying direction includes a pair of conveying rollers receiving and conveying a sheet; an endless conveying belt conveying the sheet; a plurality of balls to be rotatable in any direction while nipping the sheet with the conveying surface; a pair of regulating guides disposed on both sides of the conveying belt; a guide moving unit that moves the pair of regulating guides; and a roller moving unit that moves at least one of the pair of conveying rollers to a nip position and a nip release position. Before a rear end of the sheet passes the pair of conveying rollers, the pair of conveying rollers is moved to the nip release position by the roller moving unit, and then, the guide moving unit makes each of the pair of regulating guides reach the guide position from the retracting position.

A sheet conveyance apparatus includes a conveyance rotating member pair configured to convey a sheet in a sheet conveyance direction, a skew correction portion including a first abutment portion, and a second abutment portion that is disposed at a position different from the first abutment portion in a width direction orthogonal to the sheet conveyance direction, and a guide portion. The guide portion includes a guide surface that is disposed between the first abutment portion and the second abutment portion in the width direction and forms a conveyance path, a first recess portion that is recessed to an opposite side to the conveyance path with respect to the guide surface, and a second recess portion that is recessed to the opposite side to the conveyance path with respect to the guide surface.

An image forming apparatus includes a first roller having a first portion between tapered portions, which are at each end of the first portion. An outer diameter of each tapered portion decreases with distance from the first portion along a width direction of the first roller. A second roller has a second portion facing the first portion of the first roller and third portions, which are at each end of the second portion. The third portions face the tapered portions of the first roller. A belt of the image forming apparatus has an inner surface contacting the first portion of the first roller and an outer surface forming a nip with the second portion of the second roller. The belt has a protruding portion on the inner surface at each end of the belt in the width direction. The protruding portions face the tapered portions of the first roller.

A sheet transportation device includes a first transport roller that transports a sheet member toward a first direction, a second transport roller that is arranged on a downstream side of the first transport roller in a transport direction of the sheet member and transports the sheet member in a second direction different from the first direction, and a guide portion that guides the sheet member by coming into contact with a leading end of the sheet member in a region on a second transport roller side with respect to a first line extending from a part of the first transport roller, in which the sheet member is pinched, in the first direction and on an opposite side to a first transport roller side with respect to a second line extending from a part of the second transport roller, in which the sheet member is pinched, in the second direction.

A flexible touch panel including a flexible substrate bent in a first direction, and a touch sensor unit disposed on the flexible substrate, the touch sensor unit including a bridge extending in a second direction intersecting the first direction.

A conveyance device includes a first temperature detector and a second temperature detector that detect a temperature of a heater. A recording medium detector detects a recording medium. The first temperature detector is separated from a center position of an elastic layer of a pressure rotator farther than the second temperature detector is in an orthogonal direction perpendicular to a recording medium conveyance direction. The first temperature detector is separated from the center position for a first length and disposed in a first span defined by the center position in the orthogonal direction. The recording medium detector is disposed in a second span opposite to the first span, separated from the center position for a second length smaller than the first length, and disposed in a minimum recording medium conveyance span where the recording medium having a minimum width in the orthogonal direction is conveyed.
