Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tape drive device, and more particularly, to a tape drive device for transporting a desired tape among a plurality of tapes to a desired position and for calling a desired tape portion of the desired tape to a predetermined position. The present invention relates to a device for selectively driving tape.

For example, in order to eliminate the drawbacks of the conventional tape selection drive device for recalling a desired input item to a predetermined position in a multi-item information input device, the present inventor first developed a first roller and a first roller. It consists of a plurality of second rollers arranged in a ring around the center, a tape is wound around each second roller from one end, these tapes are gathered together from the other end and wound around the first roller, and the first and We have developed a tape drive device that retrieves a desired tape and a desired tape portion of the tape to a predetermined position by selectively rotating the second roller and turning the second roller (Japanese Patent Application No. 136538/1982). Calligraphy [JP-A-59-
(Refer to Publication No. 27371). Although this tape drive device consists of a ring gear for rotating the roller and a crown gear for rotating the second roller, the inventors of the present invention
A more efficient and compact tape drive was created.

According to the present invention, the tape drive device includes one first roller, a plurality of second rollers arranged annularly around the first roller, and a plurality of second rollers that are wound around the second roller from one end and from the other end. a plurality of tapes wrapped together around a first roller, a first ring gear that engages with gears provided on each of the second rollers, and a second ring gear that interlocks with the gears provided on the first roller; and a rotary plate rotatably mounted with first and second rollers.

To explain using the drawings, the tape drive device 1 of the present invention includes one first roller 2 and a plurality of second rollers 3 arranged annularly around this roller 2.
and a plurality of tapes 4 that are wound around each second roller 3 from one end and then wrapped together around the first roller 2 from the other end. In the present invention, the second roller 3 is rotatably mounted via a shaft 7 to a rotary disc 6 which is rotatably mounted on the shaft 5 of the first roller 2 . The shaft 5 of the first roller 2 is rotatably supported on a fixed frame 8 of the device 1 .

The tape drive device 1 further includes a first internal gear, that is, a first ring gear 10 that meshes with a gear 9 fixed to the shaft 7 of the second roller 3, and a second ring gear 12 that meshes with an idler gear 11 supported on the rotating disk 6. The floating gear 11 is connected to the shaft 5 of the first roller 2.
It meshes with gear 13 which is fixed to. The ring gears 10 and 12 are rotatably held by a known method, such as a method of slidably supporting the ring gears (not shown), so as not to move laterally.

The ring gear 10 has ratchet teeth 1 on its outer peripheral surface.
4 (FIG. 2), and the ratchet pawl 15 can selectively engage with the ratchet teeth 14 to prevent rotation of the ring gear 10 in one direction. When the ratchet pawls 15 are not engaged with the ratchet teeth 14, the ring gear 10 is free to rotate. Similarly, the ring gear 12 is also provided with ratchet teeth 16 (FIG. 3) on its outer peripheral surface, and a ratchet pawl 17 selectively engages with the ratchet teeth 16 to rotate the ring gear 12.
rotation in one direction can be prevented. When the ratchet pawl 17 is not engaged with the ratchet tooth 16, the ring gear 12 can rotate freely.

A roller assembly 20 consisting of a first roller 2, a second roller 3, a tape 4 and a rotating disk 6 is mounted on a shaft 5.
For example, a drive gear 19 that can freely rotate on the shaft 5 of the first roller and meshes with a gear 18 provided integrally with the rotary disk 6 is supported on the fixed frame 8, and a step motor or By rotating the drive gear 19 by the pulse motor 21, the gear 18 and the disc 6 integral therewith are rotated step by step, and thus the roller assembly 20 is rotated step by step.

Next, the operation of the tape drive device of the present invention will be explained. Referring to FIG. 4, for example, when it is desired to position the tape portion 4b of the tape 4a associated with the second roller 3a in the field of view VF of the operator, the second roller 3a is rotated to the position of the field of view VF (in the case of FIG. teeth
It is necessary to rotate the tape 4a counterclockwise through an angle of 90° and wind the tape 4a onto the second roller in order to convey the tape portion 4b to the guide plate 22. In this case, the ratchet pawl 17 associated with the second ring gear 12 is released from the corresponding ratchet tooth 16, leaving the second ring gear 12 in a free rotation state and thus the first roller 2 in a free rotation state. On the other hand, the ratchet pawls 15 are kept engaged with the corresponding ratchet pawls 14 of the first ring gear 17 to restrict the rotation of the first ring gear 10. In this state, the motor 21 moves the rotary disk 6 through the gears 19 and 18.
If the second roller 3a is rotated counterclockwise by an angle of 90 degrees (FIGS. 2 and 4), the second roller 3a will revolve and be transported to the field of view VF. While the second roller revolves counterclockwise, the gears 9 fixed to the second roller 3 also revolve counterclockwise.
Since the gear 9 itself (therefore, the second roller 3 itself) rotates clockwise, the tape 4 is wound onto the corresponding second roller 3. It turns out. tape 4
If the ratchet pawl 15 is released from the ratchet teeth 14 when the desired tape portion 4b of A comes onto the guide plate 22, the first ring gear 10 will revolve together with the gear 9, so the tape portion 4b will be placed on the guide plate 22.
2 and remain held on top. If the desired tape portion is located on the corresponding guide plate from the beginning, the claws 15, 17 are moved to the corresponding teeth 14, 1.
The roller assembly 2 is moved by the motor 21 while being released from the roller assembly 6.
0 to bring the desired second roller to the visual field VF. In addition, if the desired tape portion has not yet reached the guide plate when the desired second roller comes to the field of view VF, the second roller is further revolved in the manner described above, and the desired tape portion is placed on the guide plate. When reaching the top, pull the pawl 15 away from the teeth 14 and move the second
It is sufficient to stop the rotation of the roller and, in this state, transport the desired second roller to the visual field VF. Next, when positioning a desired tape portion existing within the tape portion wrapped around the second roller 3 on the guide plate and transporting the corresponding second roller to the field of view VF, the ratchet pawl 15 is released from the teeth 14. The first ring gear 10 is brought into a free rotation state and the second roller 3 is allowed to rotate freely. On the other hand, the pawl 17 is engaged with the teeth 16 to keep the second ring gear 12 in a fixed state.
In this state, when the rotating disk 6 is rotated counterclockwise (Fig. 3) by the motor 21 via the gears 19 and 18, the floating gear 11 attached to the rotating disk rotates counterclockwise (Fig. 3). It rotates clockwise (due to engagement with the second ring gear 12) while rotating the gear 13 of the first roller 2 counterclockwise (due to engagement with the second ring gear 12).
(Figure 4). Therefore, the first roller 2 also rotates counterclockwise to wind up the tape 4 together, and the second roller 2 rotates counterclockwise.
Tape 4 is unwound from roller 3. If the ratchet pawl 17 is separated from the teeth 16 when the desired tape portion is on the corresponding guide plate, the roller assembly 20 rotates while the desired tape portion is positioned on the guide plate. Related controls for positioning the desired tape portion on the guide plate and positioning the desired second roller in the field of view VF may be performed in the same manner as described above. The amount of movement of the tape may be sensed by any known means, such as a series of perforations wound around the edge of the tape and a photoelectric element for sensing these, and engagement and release control of the pawls 15 and 17 may be performed by any known means. This may be done by any suitable known means. To prevent errors due to twisting of the shaft 5, the gears 18, 19 and the motor 21 may be associated with the disk 6 on the left side (FIG. 1). Also, the rotation of rollers 2 and 3 is controlled by ring gear 1.
This may be done by directly driving the gears 0 or 12 to rotate (for example, using a normal tooth arrangement instead of the ratchet teeth and rotating them with respective gears and motors). Other suitable driving methods can be used.

Due to the above configuration, the present invention can be applied to various applications. For example, it can be used in various applications such as a multi-item information input device, a magnetic recording and reproducing device, a microfilm search device, a camera film drive device, an atlas, a memory device, a telephone exchange system, a library system, and a telephone set.

Next, by displaying personal names, company names, etc. as items on the tape, storing a corresponding telephone number, and controlling the call with a suitable electronic device, the input device of the telephone is assigned a substitute for dialing or pushing a telephone. Another embodiment of the present invention applied as a part of the present invention will be briefly described. Parts similar to those of the previous embodiments are provided with the same reference numerals.
