摘要： An image reading apparatus has a light source unit for illuminating an object to be illuminated, a reading unit for reading the object illuminated by the light source unit, a reflective unit, having at least a first reflection mirror, for reflecting reading light reflected by the object toward the reading unit, and a first light blocking portion for partially blocking light except the reading light. The first reflection mirror has a reflecting surface for reflecting the reading light, and an end surface substantially orthogonal to the reflecting surface. The first light blocking portion extends in a longitudinal direction of the first reflection mirror toward the end surface of the first reflection mirror, with a tip end of the first light blocking portion being opposed to the end surface of the first reflection mirror with a gap therebetween.

摘要： An image forming apparatus includes an image reading unit, an image forming unit, a discharge unit, and a discharge tray. The image reading unit is configured to read a document placed on a document placement table by moving and scanning of a scanning body in a sub-scanning direction. The image forming unit is configured to form an image read by the image reading unit on a paper sheet. The discharge unit is configured to discharge the paper sheet on which an image is formed by the image forming unit to a direction perpendicular to the sub-scanning direction. The discharge tray is on which the paper sheet from the discharge unit is to be placed with a space portion at a lower side of the image reading unit. A bottom surface of a housing of the image reading unit facing the discharge tray is constituted of a first surface and a second surface. The first surface is a surface at a front side of the discharge unit in a discharging direction and high with respect to the discharge tray. The second surface is a surface at a back side of the discharge unit in the discharging direction lower than the first surface with respect to the discharge tray. A pulling member and/or a movable wiring are/is arranged at an upper side of the second surface inside the housing. The pulling member is configured to move the scanning body back and forth in the sub-scanning direction. One end portion of the movable wiring is secured to the scanning body.

摘要： An image reading apparatus includes an image scanning unit that is provided with a holding portion holding a flexible flat cable. The holding portion is protruded toward an upstream side in a sub scanning direction, and provided with a second wall part. The flexible flat cable that is extended from a connector is brought into contact with the second wall part. As for the flexible flat cable, a downward movement is regulated by a lower holding portion and an upward movement is regulated by an upper holding portion. Accordingly, the flexible flat cable does not rise.

摘要： An illumination device includes a light guide member having a bar-like shape and a light source disposed so as to face an end surface of the light guide member. The illumination device guides light from the light source in the light guide member and emits the light from a light emission surface of the light guide member formed in a longitudinal direction of the light guide member. The light emission surface includes a first light diffusing portion that is formed in a first portion near the light source and that has a protruding/recessed shape, and a second light diffusing portion that is formed in a second portion adjacent to an end of the first light diffusing portion, the end being away from the light source. The second light diffusing portion has a protruding/recessed shape and has lower light diffusivity than the first light diffusing portion.

摘要： A driving device is used in an image reading apparatus, and reciprocates a scanning unit for reading an image on an original. The driving device comprises a pull member, a driving pulley which transmits driving force to the pull member, a following pulley which applies tension to the pull member and a pulley holder having a pulley axis which holds the following pulley rotatably. Then, the pulley axis has a lock pawl capable of locking an upper end portion of the following pulley and canceling engagement with the following pulley by being tilted toward a side of an axial center by elastic deformation. Furthermore, the lock pawl is arranged at a side of a tension acting direction from the pull member to the following pulley except the farthest position from the driving pulley among positions in a circumferential direction of the pulley axis. It is possible to attach and detach the following pulley easily at a time of maintenance or the like.
