Abstract

PURPOSE:To obtain a device which can transfer without hindrance even if an endless tape is used as a mother tape, by providing a means for giving tension of equal magnitude and opposite directions to each other before and after a transferring drum on the mother tape. CONSTITUTION:A mother tape 9 stored in a tape pool 18 is wound around a transferring drum 5, a slave tape is press-stuck on the mother tape, a transfer magnetic field is given from a magnetic head 11, the tapes 9 and 1 are moved in a press-stuck state and the information of the mother tape 9 is transferred to the slave tape 1. In this case, capstans 12 and 15 and pinch rollers 13 and 16 grip the mother tape, allowing to provide inverse and equal tension at a carrying-in and -out path to the drum 5. Thus, both the tapes 9 and 1 are run at the same speed and phase, allowing the eliminate the shift of transfer.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a so-called transfer device that transfers recorded information on a mother tape to a slave tape, and is particularly designed to perform transfer without transfer deviation even when an endless tape is used as the mother tape. @A general transfer device employs a configuration in which both a mother tape and a slave tape are wound around a supply reel and a defeat reel. In this way, the transport of the mother tape and the slave tape is ensured, and there is a strong possibility that misalignment will occur between them. By the way, in such a configuration, when the mother tape has been transferred from the leading edge to the trailing edge, it is necessary to rewind the mother tape in preparation for the next transfer. Extra time was required for return.

Therefore, since the mother tape is wound on a supply reel and a take-up reel, it is desirable to use an endless tape. However, since the endless tape is pulled under no tension, it has been difficult to transport the mother tape and slave tape together without causing them to collapse.

The present invention has been made in consideration of these circumstances, and particularly aims to provide a transfer device that can perform transfer without any trouble even when an endless tape is used as a mother tape.

Hereinafter, an embodiment in which the present invention is applied to a magnetic transfer device will be described with reference to the drawings.
indicates a dangerous slave tape with recorded information signals,
This slave tape (1) is fed from both ends of the supply reel (
2) and the take-up reel (3). This slave tape (1) is guided (
4) Arrange the transfer drum (5) and guide (6) and determine the transport path for the slave tape (1). There is a capstan (7) between the transfer drum (5) and the guy P (6).
) and a pinch roller (8) to connect the slave tape (
1) so that it is conveyed in the direction of the arrow & O. The transfer drum (5) K also winds the mother tape (9) on which information signals are recorded. 0 This mother tape (9) is The tape is made up of stones. Then, this mother tape (9) is arranged between the transfer drum (5) and the slave tape (1), and
The magnetic layer of the mother tape (9) and the magnetic layer of the slave tape (1) are brought into contact with each other. The mother tape (9) and slave tape (11) thus laminated are pressed together on the transfer drum (5) with a pressure roller α and pressed with a magnetic spatula PI. In this case, the capstan (7) is driven When the tape tape (1) is conveyed in the direction of the arrow 1, the master tape (9) is fed in the direction of the arrow Ki' due to frictional force.

A capstan a and a pinch roller αJ are provided in the conveyance path of the mother tape (9) from the transfer drum (5).
K is applied to apply tension in the direction of the arrow.This tension is then detected by detector I.

A similar capstan a9, a pinch roller αe, and a pinch detector αη are also provided in the conveyance path of the mother tape (9) to the transfer drum (5). However, tension is generated in the carry-in path in the opposite direction to the carry-out path, that is, in the direction of arrow C.

Here, each detection output of the detectors I and aη is controlled by a control i! (not shown). The tape is supplied to one section, and this control section increases the tension on the carry-in path and the transport system. Note that α8 in the figure is a tape reservoir.

In such a configuration, when the slave tape (1) is stopped, the mother tape (9) is at rest because the tension in the direction of the arrow ti and the direction of the arrow C are balanced. ), when the slave tape (1) runs in the direction of the arrow layer, the slave tape (
Due to the frictional force between the mother tape (1) and the mother tape (9), the mother tape (9) runs together with the slave tape (1). The tension in the direction of the arrow C is balanced 0. This is because when the tension in the direction of the arrow C tries to increase due to frictional force, the detectors αJ and Qη detect this and the control unit (not shown) activates the capstan a3. ．． This is because α9 is controlled. As a result, the mother tape (9) stably follows the slave tape (1) K and runs at the same speed and phase.

When the mother tape (9) and the slave tape (1) are transported as described above, if a transfer magnetic field is formed by the magnetic head ri1)K, the mother tape (9) will move at the same speed and phase as the slave tape (1). Because it is running at
Transcription can be performed without incurring time-based costs.

As described above, according to the transfer device of the present invention, the tension in the transport path of the mother tape (9) to the transfer drum (5) and the tension in the transport path from the transfer drum (5) are balanced. Then, the mother tape (9) is conveyed together with the slave tape (1) by friction force. Therefore, the mother tape (9) #:t runs at the same speed and phase as the slave tape (1).・For this reason, even if the mother tape (9) is an embossed tape, reliable force transfer can be performed. ・The present invention is not limited to the above-mentioned embodiments,
Of course, various configurations may be made within the scope of the invention.
