Medium storing device

摘要

A temporary storage in a medium storing device carries out ON/OFF monitoring of a jam sensor between a winding start position of a drum and a clamp point of a delivering roller. Accordingly, when bills are rewound in the reset operation, even when a relationship between a pulse count and a bill position becomes different from actual one, it is possible to detect, without using a pulse count, a jam between the winding start position and the clamp point. It is possible to more securely detect the abnormality in bill storing in comparison with the prior art.

1. A medium storing device comprising:
a drum winding a medium and storing the medium around a circumference face of the drum; a delivering roller sending the medium coming from an inlet/outlet port for winding so as to send the medium to said drum, and returning the medium unwound from said drum to said inlet/outlet port for return; a monitor monitoring a conveying path for the medium between a winding start position of said drum and said delivering roller, said monitor monitoring the conveying path regardless of a rotation amount of said drum obtained in winding, said monitor including
a sensor, which has a light emitter emitting a light beam and an optical sensor receiving the light beam on an optical axis, anda controller, the optical axis being arranged across the conveying path, said sensor being rendered conductive or non-conductive in accordance with whether or not the optical axis is obstructed by the medium, said controller monitoring whether said sensor is conductive or non-conductive to thereby determine whether or not the medium on the conveying path is abnormal; and a guide guiding the medium from a vicinity of the inlet/outlet port to a vicinity of said drum, said delivering roller being arranged in a middle of said guide, the optical axis being arranged to pass a tip end of said guide near said drum.
