SHEET CONVEYING DEVICE, AND IMAGE FORMING DEVICE HAVING THE SAME

摘要

PROBLEM TO BE SOLVED: To add and exchange only a required function when a structure of an image forming device is changed, to avoid cost rising by using the conventionally provided structure as it is, and to facilitate the change of a system. SOLUTION: The sheet conveying device comprises a delivery roller pair 23 to which rotation force in a constant direction is transmitted and a gear for transmitting the rotation force to the delivery roller pair 23. A motor unit 40 capable of normally or reversely rotating the delivery roller pair 23 can be exchanged with the gear.
