  • Patent number: 8996253
    Abstract: A movable carriage having front wheels and rear wheels includes, a detection unit detecting a direction caused by the operator pushing or pulling a grip unit, a rear-wheel steering angle changing unit changing a steering angle to cause a phase of the rear wheel to be the same as or opposite to the phase of the front wheel according to whether an angle between the detected direction and a center axis of the movable carriage is a predetermined angle or smaller, and a front-wheel steering angle changing unit changing a steering angle to cause a phase of the front wheel to be the same as or opposite to the detected direction according to whether the detected direction is a direction in which the movable carriage is pushed or pulled, when the angle between the detected direction and the center axis of the carriage exceeds the predetermined angle.

  • Patent number: 8456714
    Abstract: An image forming apparatus includes a printing section, a flatbed scanner section configured to read an original on a reading surface, and a moving mechanism configured to change the angle of the reading surface relative to an installation plane on which the apparatus is installed. The scanner section is capable of performing reading in each of a first mode where the angle of the reading surface is a first angle (vertical) and a second mode where the angle of the reading surface is a second angle (horizontal) different from the first angle.

  • Patent number: 7391541
    Abstract: It is an object of the present invention to provide an excellent image reading apparatus that realizes miniaturization and reduces a total reading time at the time of reading a transparent original and, in addition, improves operability. In order to attain this object, since the image reading apparatus has a configuration in which a light source driving circuit section is disposed to overlap in the upward direction separating from an original mounting surface of a surface light emitting section, an area occupied by the light source driving circuit section and the surface light emitting section on a horizontal surface becomes small and miniaturization can be realized. In addition, since the light source driving circuit section and the surface light emitting section can be disposed in a position close to a hinge section altogether, the center of gravity of an FAU is moved to the hinge section side, and rotatability of the hinge section becomes easy and is improved.
