Prior art shown in 80692 and the like is known. According to this prior art, a punching unit (a punching unit) having a punch is provided between a feeding mechanism for feeding out a material roll of a tape-like material and a winding mechanism for winding the tape-like material, and a tension device for holding the tape-like material in tension. This is a basic configuration provided with a tension mechanism for applying a predetermined length of the tape-shaped material in a X-axis direction by a pinch roller while punching a hole with a required punching pattern by a punch. Then, the tape-shaped material is Y-shaped due to friction with the punch or the like.
An edge that detects parallel movement of the tape-like object due to parallel movement in the axial direction, or similarly due to a slight difference in frictional resistance between a pair of upper and lower feed rollers, a feeding mechanism (feeding roll), and a winding mechanism (winding roll). Detecting means are arranged on both sides (above both longitudinal edges of the tape-shaped material), and the output mechanism of the edge detecting means controls the feeding mechanism (feeding roll) and the winding mechanism (winding roll) in the plus or minus direction (Y (In the axial direction) at the same time, and corrects it.

However, controlling the feeding mechanism (feeding roll) and the winding mechanism (winding roll) themselves requires a driving source, requires a large scale of equipment, and raises equipment costs. Further, the pair of feed rollers,
It is made of rubber and has a property of easily causing slip with the tape. Therefore, in actuality, the roller is actually operated by increasing the contact pressure so that the entire length in the longitudinal direction of the roller is in strong contact with the entire length in the width direction of the tape-shaped material, and printing is performed on the surface of the tape-shaped material. In such a case, there is a risk of damaging the print.

The rotating roller 45 is coaxially mounted on a plurality of shafts, and a plurality of the rotating rollers 45 are opposed to each other at a plurality of intervals in a tape-like material B as one unit.
The number of bearings and the distance between the bearings are arbitrary. For example, as in the embodiment shown in FIG. 4, one longitudinal edge of the tape-shaped material B can be brought into contact with the inner surface 25a. When the flat rectangular portion 5 'is provided over the entire area of the tape guide portion 5, a window hole (not shown) is formed in the upper plate portion of the flat rectangular portion 5'.
And the rotation roller 45 may be devised so as to contact the upper surface of the tape-shaped material B from the window hole in the same manner as in the case of the feed roller 6 on the upper side. Further, it is naturally preferable that the shift portion 35 and the rotating roller 45 are also provided in the tape guide portion 5 on the downstream side of the perforated portion 4, so that the tape guides on the upstream side and the downstream side of the perforated portion 4 are provided. Using the inner surface 25a of the surrounding portion 25 on the same side of the portion 4 as a guide surface, it is ensured that the tape-shaped material B is fed into the perforated portion 4.

As described above, the present invention has the following advantages. (Claim 1) A tape-shaped object in the Y-axis direction only by being installed on a machine of a punching device without causing a large increase in equipment cost as in a conventional system in which a feeding mechanism and a winding mechanism are controlled and driven by a drive source. A very convenient and simple structure perforating unit for preventing the displacement (Y-axis direction) can be newly provided. (Claim 2) In addition, since there is no slip, the quantitative intermittent feeding of the tape-like material to the perforated portion is not only highly accurate, but also the printing is not damaged, and the required perforating process is maintained at a high quality. Can be done with (Claim 3) The tape guide portion is extended not only on the upstream side but also on the downstream side of the perforated portion, so that the displacement of the tape-like material in the Y-axis direction can be prevented more accurately. (Claim 4) In addition, the feedback of the centering data,
A constant amount of quantitative feed in the direction of the X-axis to the perforated portion of the tape-shaped material with a pair of feed rollers is always maintained with high precision. Even if the feed amount by the feed roller gradually decreases, there is no fear that a drilling error occurs. (Claim 5) When the tape guide portion is formed in a flat rectangular shape having both ends opened, with at least a portion approaching the perforated portion as a tape guide space inside, the tape-like material entering the perforated portion is formed. Dancing upward can be prevented, and accurate drilling can be performed. (Claim 6) In addition, the tape guide portion includes a shift portion for abutting against the longitudinal edge of the tape-shaped object and slightly pressing the tape-shaped object in the width direction at one of the portions enclosing the longitudinal edge of the tape-shaped object. If so, the shift portion slightly pushes the longitudinal edge of the opposing tape-shaped object in the width direction to bring the opposite longitudinal edge into contact with the inner surface of the opposite surrounding portion, and the opposite side With the inner surface of the surrounding portion as a guide surface, the tape-like material is fed into the perforated portion without swinging in the Y-axis direction (without meandering) without being influenced by the clearance of the tape guiding portion. Convenient for good drilling. (Claim 7) The tape guide portion includes a rotation roller on one side portion which is inclined outwardly in a plan view with respect to the feeding direction of the tape-shaped material, and the rotation roller is provided near the longitudinal edge of the tape-shaped material. The same effect as in claim 6 can be expected also in the case of a configuration in which the upper surface is brought into contact with the upper surface and driven to rotate by the abutting force, and the shaft can be axially attached to the upper surface of one of the surrounding portions from above. However, the structure is simple.
