2. Description of the Related Art In recent years, the processing speed of continuous forms has been increased. For example, in a printing operation using a non-impact printer, high-speed printing of 10,000 lines or more per minute is possible. It is progressing further. However, in order to take advantage of the reduction in processing time, the length of continuous forms must be sufficiently longer than before.
If this is short, the continuous form must be frequently re-set at a predetermined position, resulting in poor work efficiency. More specifically, a continuous report with a depth of 11 inches
The print processing time when stacked at a height of 0 cm is 12,
Although it takes about three minutes, the time required for resetting this takes a few minutes, and the resetting time in the entire printing work time is about 20%.

Although it is possible to lengthen one continuous unit of a continuous form, it is difficult to fold the extended continuous form and stack it in a high position at a predetermined position in a desired state where no bending occurs. There was a demand for the development of a continuous form installation member that makes this possible. In the past, as a solution to this demand, a Japanese Utility Model Application No. 61-7456 has already been proposed.
A long form storage box described in Japanese Patent Publication No. 1 has been proposed.
