In the booklet fixed number reversing and accumulating device in which a predetermined number of bookbinding groups are lifted up and transferred to the delivery table by dropping and supplying them onto the group, the left and right sides of the turntable (46) Is cut into a bowstring shape to form a symmetric cut surface in the left-right direction, and a large number of rollers (47a) are arranged at appropriate intervals in the diameter direction of the turntable (46) parallel to the cut surface. Parallel 2 installed in parallel The transport section (47) is provided, and the set number of booklets (21) dropped and supplied are transferred to the outside of the turntable (46) in the concave groove (48) provided between the both transport sections (47). The pusher (25) is provided movably, and the left and right parts on the front and rear surfaces of the turntable (46) are fitted to the four corners of the bookbinding (21) supplied on the turntable (46), In addition, the vertical frame rod (50) having the frame piece (50a) capable of rotating and returning is disposed at the loading position at the loading position at symmetrical positions in front of and behind the turntable (46). Horizontal frame rods (51), which are staggered and opposed to each other, are attached to both frame rods (50) on the same side of the groove (48), and the upper frame rods (51) are connected. The rack teeth (52) are formed on the lower surface, and the rack teeth (52) are formed on the upper surface of the lower connecting rod (51), which is opposite to the side where the rack teeth (52) are formed. Respectively scale (53) provided on the surface, the rack teeth (5 of both continuous rod (51)
A pinion (54) which meshes in common with 2) is provided so as to be movable and fixed in the middle of both the frame rods (50) and in the direction orthogonal to the longitudinal direction of the connecting rod (51). With
