Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to tape drives, and more particularly to tape drives that simultaneously move multiple tapes by the same amount.

[Prior art]

Ganto Kagawa had previously developed a so-called flat type tape drive system with a special input capacity as an input device that could extremely quickly change the input items displayed on the keyboard (see Japanese Patent Application No. 124877/1983). ). According to the flat type tape drive system, as shown in FIG.
A tape 2 on which a large number of input items are written in a vertical and horizontal matrix is wound from one end of the tape 2, and these tapes are wrapped together from the other end of the tape around a second roller 6 arranged parallel to the first roller. Either the first roller 1 ft is simultaneously rotated by the same amount in the same direction by an appropriate means such as a belt drive or the like, and the plurality of tapes 2 are simultaneously wound by the same amount onto the first roller, or the second roller 6 is rotationally driven to wind the plurality of tapes 2 by the same amount. It has a structure in which the same amount of the same amount is wound onto the second roller 3 at the same time. When such a tape drive system is used to change the input items on the keyboard, it is very convenient because the display of the input items on the keyboard can be quickly changed (page change) by simply moving the tape one row of the matrix. Satisfactory results can be obtained, and there is also the advantage of dramatically increasing the number of available input items. However, if the number of first rollers increases considerably, the amount 4 of the tape wound around the second roller 6 will increase, so there is a risk that errors in tape movement will occur due to tape thickness.

[Purpose of the invention]

An object of the present invention is to provide a tape drive device that does not cause any errors in tape movement as described above.

[Structure of the invention]

According to the present invention, a slide par is provided in place of the second roller, the other ends of the plurality of tapes are fixed together to the slide par, and the slide par is slidably driven, so that each first roller The structure is such that the corresponding tapes are unwound in the same amount at the same time.

〔Example〕

To explain the present invention using figures, as shown in Fig. 2,
In principle, the tape drive device 10 of the present invention has a central axis 15t located in a common plane P, is arranged parallel to each other, and has a regular polygonal or circular cross section (the one shown is a regular pentagonal cross section). (example) a plurality of first rollers 11, a plurality of tapes 12 corresponding to each first roller, and a fixed rotating guide roller 13.

The tape 12 is wound from one end around the corresponding first roller 11, guided around a guide roller 16, and the other end 16 of the tape is brought together and fixed to the slide par 14. Become. By moving the slider 14 in the direction in which the tape 12 is pulled out from the guide roller 16 (preferably in the direction of the horizontal arrow A), the same amount of tape can be unwound from each first roller 11 at the same time. Therefore, when the slider 14 has a regular pentagonal cross section as shown in FIG. 11l of each of the four first rollers 11 that have been present in the input item display plane P'
Instead of the 11th side S, the side SI on the left (for each first roller) is simultaneously positioned on the plane P', and the input items written on the tape section above the side S are newly displayed (1 page change). If you move the slide par N steps.

- You can change 8 pages at a time.

On the other hand, if the first roller 11 is simultaneously rotated counterclockwise by 72c' (Fig. 2), the side surface S2 on the right side is positioned on the plane P', and writing is performed on the tape portion located above these side surfaces S2. Manpower items are displayed in new format.

A left rotation of 72°×M of the first roller 11 corresponds to a negative page change of M. Any suitable known means can be used for the movement of the slide, the driving means, and the simultaneous rotation driving means for the first roller, and a suitable example thereof will be described later in connection with the description of the embodiments in FIGS. 3 to 6. .

It consists of a roller 26 and an elongated slider 26 located between guide rollers 25 and 26 and capable of reciprocating horizontally in the direction of arrow B and extending parallel to the 10L channel. tape 2
2 is wrapped around the corresponding first roller 21 from one end thereof, and the other end 62 of the tape is held together and fixed to the slider 26. Also, the tape 22 starts from each first roller 21, gathers together, passes around the fixed guide roller 24, and then passes through the OT moving guide roller 26.
It passes around another fixed guide roller 25 and extends to the slide par 26. In order to avoid contact between the tape bundles 22' passing around the guide rollers, in the preferred embodiment shown, the guide rollers 24.2
The central axes 28, 29 of the rollers 6 are located on the same horizontal plane, and the other guide roller 25 has a smaller diameter than the guide rollers 24, 26 of the pond, and its central axis 61 is located above the horizontal plane.

However, it goes without saying that the invention is not limited to this example.

Preferably, the slider 23 and the movable guide roller 26 move as one, and an example of their driving is shown in FIG. 4. The moving part in FIG. 4, the IH device 60, is a lightweight concave carriage 6.
2, the shaft 29 of the movable guide roller 26 is pivotally supported on both side walls 66 of this carriage, and both ends of the slider are fixed. The carriage 32 can reciprocate horizontally in the direction of arrow B (FIG. 3) by a guide bracket 65 that engages with a pair of guides 11134 provided on the tape drive device 20, and the carriage 62 can move to the right (FIG. 3). The movement is
This is done by winding a wire 661 fixed to the carriage 62 around a fixed rotary pulley 67 driven by a step motor or pulse motor 68.

The carriage 62 is guided by a guide wheel 41 pivotally supported on the carriage side wall 36 as shown in FIG. 4A instead of the guide bar 341 and guide bracket 35 shown in FIG.
and the guideway 4 of the device 20 that engages these wheels.

Finally, in order to remove any slack that may occur in the tape 22 between each of the first rollers 21 (FIG. 3) and the slider 26, a tension roller or the like (not shown) is preferably used to remove each tape. The tape may be maintained under tension, or each first roller may be biased in a counterclockwise (FIG. 3) direction by any suitable known biasing means such as spring means or elastomers to apply pack tension to the tape.

To explain the operation of the tape drive device 20 shown in FIGS. 3 to 6,
Its operating method is almost the same as that in Figure 2, but the
The case shown in the figure differs from that shown in Fig. 2 in that when the slider is moved by the same amount, twice the amount of tape is unwound from the first roller compared to the case shown in Fig. 2. Therefore, if the length of the stroke S of the slider is set to the same value, in the -g device shown in Figure 3, approximately twice the amount of tape can be wrapped around each first roller compared to the device shown in Figure 2. The amount of information written to or to be stored on tape is thereby approximately doubled.

Now, the operation of the tape drive device 20 as applied to a keyboard input device will be explained. In this case, keyboard input items can be quickly changed.

That is, in the rest position shown in Figure 1 (Figure 3), the input items written on the tape portion on the upper surface S of each first roller 21 located on the display plane P' are displayed on the IJ rack-shaped keyboard. Displayed. If the item you wish to input is displayed on the keyboard, when you press the switch corresponding to the desired item among the switches (not shown) arranged in a matrix corresponding to the input item, the Outputs corresponding to desired items are output from the keyboard, depending on the address, memory, control section, etc. On the other hand, if the item you wish to input is not displayed on the plane P', press the start button (not shown) to activate the motor 38, and move the carriage 32 (therefore) until the desired item is positioned on the plane P'. , slide par 2

Allow the first roller to rotate freely. Tape 2 is used to position the new desired input item on the plane P'.
2 must be wound around the first roller 21, the clutch 69 of the carriage drive means is used. Along with separating, the fifth.
All the first rollers 21 are rotated to the left (FIG. 3) by a roller driving means as shown in FIG. 6 until the desired item is positioned on the plane P'. The entire stroke S between the rest position and the maximum stroke position (chain line position) of the slide par 26
The length of the tape 22 is set so that all input items are selectively displayed while moving.

Note that the number of fixed guide rollers 24, 25 and movable guide rollers 26 is not limited to the number shown in FIG. 3. for example,
Fixed guide rollers 51.52.53 as shown in FIG.
and moving guide rollers 54, 55 and slide par 23
may be placed. In this case, compared to the one in Figure 2,
With the same amount of slide bar movement, four times as much tape is unwound from the first roller.

Although the present invention has been described in detail as applied to a keyboard input device, the tape drive device of the present invention is not limited to a keyboard. For example, if the tape is a magnetic tape and the
If one or more magnetic heads are provided corresponding to the surface S of a 0-year old, it can be applied to a magnetic recording/reproducing device, and if the tape is used as a microfilm and a microfilm reader is provided at the appropriate location, it can be used as a microfilm retrieval device. It can also be applied to various other applications such as idle talkers, telephone exchanges, and inputs for centralized information management and processing systems.
