摘要:
A sheet feeding device includes a feeding unit that feeds a sheet; a rolling member that rolls by having contact with the sheet being fed by the feeding unit; a supporting member that moves along with a behavior of the sheet with supporting the rolling member so that the rolling member rolls in a feeding direction of the sheet at a predetermined position on the sheet; an acceleration measuring unit that measures accelerations acting on the supporting member in three directions; and a detecting unit that detects a feed error of the sheet based on the accelerations measured by the acceleration measuring unit.

There is provided a paper feeding device including: a microphone which detects sound occurred on a paper conveying path; a pre-processing unit which performs pre-processing on a signal of the sound detected by the microphone; and a jam detection unit which detects a jam of paper based on the sound signal on which the pre-processing is performed, a reference value about intensity of the sound, and a reference value about a duration time of the sound.
摘要:
A medium supplying apparatus includes a separation mechanism that separates one medium at a time from a plurality of sheet-shaped media stacked in a loading rack and transports the medium, an irradiation unit that emits light onto a surface of the medium, and a light receiving unit that receives reflected light that is acquired by allowing the light emitted by the irradiation unit to be reflected from the surface and detects a reflected light intensity that is an intensity of the reflected light. The separating force of the separation mechanism that is used for separating a next medium is controlled based on the reflected light intensity detected by the light receiving unit.
