Title:
LIFT DEVICE, SHEET FEEDER, AND IMAGE FORMING DEVICE
Document Type and Number:
Japanese Patent JP2022129589
Kind Code:
A
Abstract:
To prevent a resetting operation with a simple structure when an output pulse of a rotary encoder is used for determining the state of a lift member.SOLUTION: An encoder rotor 17 has a plurality of count targets 170 rotated in linkage with a coupling member 15 and arrayed in a peripheral direction. Each of the count targets 170 includes a plurality of detected parts 17a spaced apart from each other in the peripheral direction. A detection sensor 160 detects the detected parts 17a at detection positions, and outputs a pulse signal. A tail detected part 172 located at a rearmost part in a main rotational direction among the detected parts 17a is formed longer in the peripheral direction than the other detected parts 17a. A count unit 8e resets the count number of pulse signals when a pulse signal having a width exceeding a reset width is output during execution of a main driving operation by a driving device 14.SELECTED DRAWING: Figure 5
