Paper sheet processing device

A paper sheet processing device comprising:

• an accommodating part that accommodates a paper sheet;
• and
• a sliding stage part that is accommodated within the accommodating part and supports the paper sheet accommodated within the accommodating part, a movable portion of the sliding stage part sliding in a first direction with respect to the accommodating part to cause the movable portion of the sliding stage part to protrude to outside of the accommodating part, the sliding stage part sliding in the first direction with respect to the accommodating part to push the paper sheet to the outside of the accommodating part and cause a leading end of the paper sheet to protrude to the outside of the accommodating part, the sliding stage part sliding in a second direction with respect to the accommodating part and being housed within the accommodating part after the sliding stage part slides in the first direction, the second direction being opposite to the first direction,
• wherein the accommodating part includes:
• an upper surface that supports a side of the paper sheet, a position of the upper surface being maintained when the sliding stage part slides in the first direction and in the second direction;
• and
• a high friction member that is fixed to the upper surface, is in contact with the side of the paper sheet, and has a higher friction coefficient than that of the upper surface, and
• wherein the high friction member maintains a position of the paper sheet when the sliding stage part slides in the second direction, to cause the leading end of the paper sheet to be maintained to be protruded to the outside of the accommodating part.
