Abstract:
A multi-function peripheral includes an image forming unit having an image forming device, and an image reading unit having an image reading device and located above the image forming unit. The image forming device forms an image on a recording sheet with moving a carriage reciprocally in a predetermined horizontal direction. The image reading device reads an image of an object by moving an image capturing element in the predetermined horizontal direction when the image forming unit operates. Spring elements are provided between the image forming unit and the image reading unit to apply an urging force therebetween in a direction parallel to the predetermined horizontal direction. The spring elements satisfy the following condition: f f n > 2 , where, f and fn are characteristic frequencies of the image forming unit and the image reading unit, respectively, in the predetermined horizontal direction.
