Title: Paper sheet delivering stack device
Inventor: TAKEMOTO TAKATOSHI
IPC: B65H1/26
Filed: 1989-12-21
Abstract: PURPOSE:To observe a paper sheet motion from the outside by installing a removable upper cover member which covers the front surface of a shake-down means, and disposing a removable transparent lower cover member which makes visible recognition of a falling paper sheet possible from the front surface. CONSTITUTION:In the receiving part 20 of a stack device, a paper sheet M is delivered in a long sideways posture, and dropped downward in a longitudinal posture by a shake-down means 22. The dropped paper sheet M is delivered to a separating means on a downstream side through paper sheet guides 25a, 25b installed in a shallow and smooth curve so that curl or crimp of the paper sheet may not be generated. A transparent lower cover member 28 which covers a downward front surface from the shake-down means 22 where the paper sheet is dropped is constituted by a transparent unit. It is thus possible to observe a falling paper sheet from the outside sufficiently, and the paper sheet rotates and falls smoothly without paper sheets side edges' coming into contact with a wall at the time of turning from the long sideways posture to the longitudinal posture because an expanding part of round sectional shape is formed.
