Abstract

PURPOSE:To take up a tape with proper length for a short time and to take up a magnetic tape with proper length on a tape hub independently of the length by forming a magnetic erase head on a soft tape winding process for take-up in a short time and erasing a Cue signal for take-up of proper length. CONSTITUTION:An interface 24 detects the timing passing erase starting point 29 and an erase end point 30 through a magnetic erase head 25 on the basis of the timing passing the Cue signal through the magnetic head 8, the rotational frequency of an encoder 11 and the interval between the magnetic head 8 and the magnetic erase head 25, and the interface 24 outputs an erase signal to the magnetic erase head 25 during the period from the time passing the erase starting point 29 through the magnetic erase head 25 to the time passing the erase end point 30 through the magnetic erase head 25 to erase the Cue signal 26 recorded in a magnetic tape completely. Subsequently, the interface 24 sends a stop signal to a magnetic tape winding motor driving device 18.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to an RFI winder control system.

Conventional structure and its problems In recent years, the production of soft tapes on which music, English conversation, etc. are recorded has increased in the magnetic chip industry, so the winding speed from the soft tape supply unit to the cassette winding tape hub has increased. 141%T, a tape winder is required. However, when the tape fed from the supply section is cut off at the magnetic chip winder stop F signal (hereinafter referred to as "Cue I") recorded on the tape and then turned to the chip hub, , the (ue times signal position may shift and be quamped. If such a soft tape is played with 71J!1 mi, the cue signal may be reproduced, so the Round winding 1
A magnetic tape winder with good heat resistance and its nitric tape winder control device have been attracting attention.

The conventional example will be described in more detail as shown in FIGS. 1 to 3. In other words, 1 is a magnetic tape pancake on which a soft signal is recorded, 2.3 is a guide bin, and 4 is a magnetic tape pancake.

．． 14 is a tape cutter, 16 is a fixed part that holds the tape clamper driving part 12.15 and the tape cutters 13 and 14, 17 is a microcomputer connected to the interface 10, and 18 is something connected to the interface 10. 20 is a tape hub attached to the cassette half 19, 21 is a magnetic tape take-up motor 11, 22 is a tape recorder's (UNN)

First, the magnetic tape 7 is moved from the pancake l to the guide bin 2.
3 and is wound around the tape hub 6 during winding of the magnetic tape. At this time, the signal recorded on the magnetic tape 7 is detected by the MiQ head 8, and from this signal, only the cue signal is detected by the Bandhus filter 9, and the cue signal is transmitted to the interface 10. On the other hand, the encoder 11 for measuring the winding length of the magnetic data 170

The number of rotations is counted from after C1 until the magnetic tape winder stops, and the number of rotations is transmitted to the interface 10.

The microcomputer 17 determines the appropriate range, whether it is large or small, and whether the winding length is appropriate. If the winding length is large, the magnetic tube winding number motor drive device 18

If the number of rotations of the encoder is less than the appropriate range of 1, a winding signal υ is sent to the magnetic chive winding motor drive device 18, and winding is performed until the number of rotations of the encoder falls within the proper range. These series of operations are as shown in the flowchart in Figure 3.4-In this way, by winding the 4ikl E tape to an appropriate length around the tape hub 6, the part where the cue signal is recorded will be cut by the tape cutter. Make it between 13 and 14. Next, tape clamper driving part 1
By moving the fixed part 16 from which the tape cutter 13.15 and the tape cutter 13.14 have been removed to the right side with respect to the plane of the paper, the magnetic chia is pressed against the chigatsu tab 4.5, and the tape clamper driving part 12.15 is pressed. Flang it with this, and at the same time cut the 7 high air tape with tape cutter 13°14. As a result, the tape hubs 5.6 are paired together to form a tape hub 20.23 for cassette tape. After taking out the tape hub 5-6, the tape hub 4 on which the magnetic Qiagua is flung is moved to the position where the tape hub 6 was located, and the magnetic tape is wound onto the tape hub 4.

Here, the number of rotations of the encoder 11 is particularly controlled by the interface 10 and the microcomputer 17, and the part where the cue signal is recorded is cut by the tape cutter 13.
．． The reason why it is set to be in the middle of 14 is as follows. That is, in the cassette tape shown in FIG. 2, when the magnetic tape is completely wound around the tape hub 23, the recorded portion of the cue signal is This is because if you do this, even if you play this cassette tape with a tape recorder, the cue (if number) will not be played. In order to record the Cue number recording part up to the point where the recorder's head contacts, it is necessary to control the rotational speed of the encoder so that it falls within an appropriate range.

However, in the first formation such as rliJ Kawami,
After winding the tape once, check again depending on whether the encoder rotation speed is within the appropriate range. If
Since it is necessary to perform winding (% CC chip winding #) or unwinding, there is a problem in that it takes a lot of time to properly wind the magnetic tape around the tape hub.

Structure of the Invention The present invention provides a magnetic tape winding machine for winding a soft tape 0 one turn at a time from a soft tape supply section to a tape hub, in which a number of turns of soft signal are separated by a magnetic tape winder stop signal. In addition to installing a magnetic winder stop signal detection device in the soft tape feeding portion, Ml air winding is performed after detecting the magnetic winder stop signal until the direct winder stops. This system is equipped with a 7υEQ tape winder stop signal erasing device to eliminate the stop multiplier υ.As a result, it is no longer necessary to strictly control the entire encoder rotation speed as in the conventional example. Moreover, it is possible to wind up the magnetic tape by an appropriate amount in a short time.

This (ue signal is transmitted to the interface 24, and the timing when the erase start point 29 and the erase end point 30 shown in FIG. 5 pass through the magnetic erase head 25, the timing when the cue signal passes through the magnetic head 8, and the encoder) 11 and the distance between the magnetic head 8 and the magnetic erasing head 25, the interface 24 detects the erasing end point from the time when the erasing start point 29 passes the magnetic erasing head 25).

A stop signal is sent from the interface 24 to the magnetic tape take-up motor drive device 18 so that the hkl 'Ai tag take-up motor stops at the timing when the part where No. After that, as in the conventional example, drive the tape clamper into the tape hubs 4 and 5 and cut the magnetic tape to create a pair of cassette tape hubs.Furthermore, take out this pair of tape hubs and start winding the tape. .Thus, the conventional Glf
By installing a magnetic erasing head on the %DAG winding machine and erasing only the CLE signal, it is possible to erase the bale of magnetic tape once wound onto the tape hub as in the past.
