Title:
MEDIUM CARRIER DEVICE
Document Type and Number:
Japanese Patent JP2018184284
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a medium carrier device capable of preventing a sensor's erroneous detection due to external light for a plurality of transport-medium detection sensors.SOLUTION: A medium carrier device is constituted of a housing having a medium taking port, transport means for transporting a medium taken from the medium taking port, and a light emitter and light receiver, and comprises a plurality of transport-medium detection sensors that are provided in a transport direction due to the transport means, a light-emitter-turning-on/off control unit that controls turning on and off of the light emitter, an external-light determination processing unit that determines whether or not the incident external light on the medium taking port is being incident on the light emitter on the basis of a result of an output signal of the light receiver upon turning-off of the light emitter, and a control unit that controls a detection control way of the transport-medium detection sensors on the basis of a determination result of the external-light determination processing unit. When it is determined that external light is being incident by the external-light determination processing unit and a change condition is satisfied, the detection control way of the transport-medium detection sensors is changed.SELECTED DRAWING: Figure 8
