Filed: 1998-05-25
Abstract: PROBLEM TO BE SOLVED: To improve the strength of a folding mechanism and holding force by thickening an opening/closing claw to be inserted between the surface paper of a paper cylinder and a surface side folding flap. SOLUTION: The back side folding flap 1A of a paper cylinder 1 is held by a catching claw 5 fitted to a bottom folding drum 4, and only the flap 1A is folded to the surface paper side of the paper cylinder 1. In this operation, although surface and back side folding flaps 1A, 1B to be held by the catching claw 5 are developed flatly along the periphery of the drum 4, most of the residual paper cylinder 1 falls into the caved part 73 of the drum 4 by its own weight so that a wide space is formed between the surface paper of the paper cylinder 1 and the surface side folding flap 1A. Therefore, an opening/closing claw 90 which folds the flap 1A by being inserted between the surface paper of the paper cylinder 1 and the flap 1A can be thickened, and the draw-out of the flap 1A from the claw 90 can be prevented.

Abstract: PURPOSE:To expand the dynamic range of automatic gain control (AGC) by controlling a program variable attenuator inputting an electric signal converted from an inputted optical signal by a signal obtained by digitizing DC voltage corresponding to the input optical signal level. CONSTITUTION:An optical signal inputted to a photoelectric conversion circuit 1 is converted into an electric signal and the electric signal is amplified by a signal amplifier 2 and inputted to the program variable attenuator 3.

The variable attenuator 3 is controlled by the digital signal from the converter 5 to keep the signal level from the amplifier 2 at a prescribed constant level and transfer its output from an output terminal 4 to the succeeding circuit. Since the attenuator 3 is controlled by the digital signal, the AGC operates in a wide dynamic range.
