Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tape storage case for paper tape used as a data recording medium.

Paper tape is currently widely used as a recording medium for manual data in relatively small-scale computers, particularly as a recording medium for command data for numerical control.

As computers have become more popular for processing data, it has become more common for a relatively small amount of original commands to be applied to the computer, and the computer to process the command data to generate a large amount of data.

For example, APT (au-to-atisfaction) in numerical control
In an automatic programming system called Cally Programmed Tool, if relatively short and simple data that describes the definition of a shape and how to trace the shape is input into the system using a language similar to English, it generally produces a three-dimensional image. Even in the case of a three-dimensional object with a complex shape, it is generated as an output.

The amount of numerical control command data has become large, and when paper tape is used as a recording medium, the length of the numerical control command data is often several hundreds of meters.

Conventionally, when using long-duration tape in paper tape leaders, tape winders have often been used.

The function of the winding machine is to have a supply side re-rail and a storage-side reel.A paper tape with a length of several tens of meters to 150 meters is wound on the supply side reel. In order to read the recorded information, the tape is run in one direction according to instructions from a computer or other control circuit, and as shown in Figure 1, the reel 1 on the supply side unwinds the paper tape 2 and moves it toward the guide post. The tape 2 is supplied to the leader head 3 through the reel 7, and the reel 4 on the storage side
It operates as if winding up 5 tapes that have been fed out.

Since the operation of the reader head 3 normally involves repeating the start and stop of running the tape, a mechanism for starting and stopping the reel 1 on the supply side as well as the reel 4 on the storage side is required.

Generally, the tape reader device 6 is standardized, and there are restrictions on the dimensions of the supply reel 1 and storage reel 4, making it difficult to increase the reel diameter. It cannot be processed.

The purpose of this invention is to solve the problems of the conventional technology, namely, the increase in the size of the tape leader device due to the increase in the size of paper tape supply and take-up reels caused by the use of ultra-long tapes, and as a result, the start and stop problems. It is an object of the present invention to provide a novel tape storage case capable of solving the drawback that the paper tape feeding mechanism becomes complicated due to the increased load due to its enlargement.

According to the storage case of the present invention, it is possible to use ultra-long tapes that are 20 times longer than conventional tapes.

Next, the present invention will be described in detail with reference to the drawings.

FIG. 2 shows a tape reader device that employs a tape storage case according to the present invention. In the figure, a cassette-type tape storage case 9 stores a paper tape 8 with processed fold lines.
The receiver is engaged with the stand 10 and serves as a tape storage case on the supply side.

An end 11 (hereinafter referred to as a start point) of the tape 8 is taken out and engaged with a feed mechanism 13 provided on a reader head 12, and the paper tape 11 is started and stopped for reading.

A tape guide 20 fitted and fixed by spring actions 18 and 19 into a guide pole 16 and a guide post 17 disposed on the tape reader device 15 is located approximately at the center of the entrance of the tape storage case 21. The lower receiver is guided by the tape storage case 21 for storing paper tapes hooked to the stand 10, and is allowed to fall naturally into the case 21 according to the fold lines 22 of the pre-processed paper tape. They are sequentially folded and stacked for storage.

FIG. 3 shows a perspective view of the tape storage cases 9 and 21 of the present invention, and FIGS. 4 and 5 are partially detailed views.

In FIG. 3, the lid 23 constituting the bottom surface of the main body of the tape storage cases 9 and 21 has a leaf spring 30 on its inner surface, the paper tape holder is engaged with a plate 25, and is rotated on a hinge 24. Accordingly, one end face of the tape storage cases 9 and 21 becomes an opening window 26, forming an entrance and exit for the paper tape.

A paper tape tray 25 is engaged with the lid 23, and the paper tape tray 25 has a convex shape with a chevron-shaped central portion, and the paper tape that falls naturally from the opening window 26 due to gravity falls onto the top surface of the tray 25, and the tray 25 is engaged with the tray 25. Following the inclined surface 27, the paper tapes reach the corners 28 of the main bodies of the tape storage cases 9 and 21, are folded back at the fold line of the paper tapes, and are successively folded and stacked.

As a result, the paper tape may bend in the middle, resulting in irregularities.
It can be stored neatly without causing problems.

In order to take out the paper tape stored in the tape storage case in the above-mentioned manner through the opening window 26 provided at the top of the tape storage case 21 in the stacking direction 31 for the purpose of engaging the reader head 12 shown in FIG. In order to pull up the paper tape stored in the tray 25 in the stacking direction 31, the tape tray slides the handle 29 provided on the tray 25 in the slit 32 and pulls the paper tape through the opening window 26. It is made so that it can be pulled out.

This is shown in FIG. Further, the tape storage cases 9 and 21 according to the present invention can be turned 180 degrees, that is, turned upside down, so that the leading and trailing ends of the stored tape can be reversed and the direction of tape withdrawal can be changed.

In normal use, it is necessary to resupply the reader head 3 when the supply of stored paper tape is completed and becomes empty.

Conventionally, in the case of a tape reader device 6 having a tape reel 1 shown in FIG. 1, it was usually necessary to rewind the paper tape when resupplying the paper tape.

However, by turning the tape storage cases 9 and 21 of the present invention by 180 degrees, and changing the position of the receiver from left to right using the stand 10, i.e., changing the tape storage case 9 on the storage side filled with paper tape to the tape storage case 9 on the supply side. By changing the position to 21,
Transfer the paper tape to the reader head 12 without rewinding.
resupply is possible.

When converting the tape storage case 21 filled with paper tape, it is necessary to close the tape storage opening window 26 in advance, so it is necessary to close the opening window by rotating the lid 23. It won't happen.

As a result, it is necessary for the tape receiver to engage the plate 25 and the lid 23, and the tape receiver is characterized in that the lid 23 can be opened and closed by engaging them with each other using a telescopic leaf spring 30.

In the storage case of this invention, in order to have the reader head read the paper tape filled in the tape storage case,
In the process of engaging the paper tape with the reader head, pull up the tray for the folded, stacked and stored paper tape together with the paper tape toward the opening window provided on the top surface of the tape storage case, and then pull the paper tape's tip up. can be easily taken out.

In FIG. 5, when the tray 25 is pulled up in the direction 31 of the opening window, the tray 25 storing the paper tape must not be tilted.

In the unlikely event that the tape storage case is tilted, the side of the tape storage case and the receiver will pass through the gap 34 caused by the tilting of the tray.
7. There is a risk of falling.

Therefore, the tray is characterized in that it satisfies the above-mentioned function by providing anti-tilting guides 33 and 35 to keep the stacked paper tapes horizontal.
