Image reading apparatus and image forming apparatus having a guide member
An image reading apparatus includes a movable body supported so as to be movable along a support table, the movable body supporting at least a light source; a controller that controls the light source; a connection member that electrically connects the movable body and the controller together, the connection member formed into a strip shape whose longitudinal direction extends in a direction in which the movable body moves and whose lateral direction extends in a widthwise direction, the connection member including a folded-back portion that is folded back in a direction opposite to the direction in which the movable body moves; and a guide member disposed along the connection member, the guide member having a high flexural rigidity in a portion that extends along the direction in which the movable body moves, the guide member having a low flexural rigidity in a portion corresponding to the folded-back portion.
1. An image reading apparatus, comprising:
a movable body supported so as to be movable along a support table on which an original document is supported, the movable body supporting at least a light source;
a controller that controls the light source;
a connection member that electrically connects the movable body and the controller together, the connection member formed into a strip shape whose longitudinal direction extends in a direction in which the movable body moves and whose lateral direction extends in a widthwise direction that crosses the direction in which the movable body moves, the connection member including a folded-back portion that is folded back in a direction substantially opposite to the direction in which the movable body moves; and
a guide member disposed along the connection member, the guide member having a high flexural rigidity in a portion that extends along the direction in which the movable body moves, the guide member having a low flexural rigidity in a portion corresponding to the folded-back portion of the connection member,
wherein the guide member includes a narrow portion disposed corresponding to the folded-back portion of the connection member when the movable body is located at a predetermined stand-by position, the narrow portion having a smaller width than other portions of the guide member.
2. An image reading apparatus, comprising:
a movable body supported so as to be movable along a support table on which an original document is supported, the movable body supporting at least a light source;
a controller that controls the light source;
a connection member that electrically connects the movable body and the controller together, the connection member formed into a strip shape whose longitudinal direction extends in a direction in which the movable body moves and whose lateral direction extends in a widthwise direction that crosses the direction in which the movable body moves, the connection member including a folded-back portion that is folded back in a direction opposite to the direction in which the movable body moves; and
a guide member disposed along the connection member, a portion of the guide member being bent with respect to the widthwise direction, the bent portion of the guide member being elastically deformable so as to be flattened in the widthwise direction in a portion corresponding to the folded-back portion of the connection member,
wherein the guide member includes a narrow portion disposed corresponding to the folded-back portion of the connection member When the movable body is located at a predetermined stand-by position, the narrow portion having a smaller width than other portions of the guide member.
3. The image reading apparatus according to claim 1 , wherein the guide member is electrically grounded and electrically conductive.
4. The image reading apparatus according to claim 2 , wherein the guide member is electrically grounded and electrically conductive.
5. An image forming apparatus, comprising:
the image reading apparatus according to claim 1 that reads an image on an original document; and
an image recording unit that records an image on a medium on the basis of the image read by the image reading apparatus.
