[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a magnetic recording / reproducing apparatus, and more particularly to a member for improving the contact of a tape with an audio control head in a tape running system.

[0002]

[Prior Art]

 FIG. 3 is a plan view showing a part of a running system of a conventional magnetic recording / reproducing apparatus. In the figure, 1 is a magnetic tape, 2 is a voice control head, 3 is a capstan, 4 is a drum, 5 is a pinch roller. , 6 is a fixed guide on the tension adjusting arm 6A, 7 is a fixed guide, 8 is a roller, 9 is a tape guide A, 9a is a roller fixed to the tape guide A9, 9b is a fixed guide fixed to the tape guide A9. 10 is a tape guide B, 10a is a roller fixed to the tape guide B10, 10b is a fixed guide fixed to the tape guide B10, 11 is a fixed guide, 12 is a roller fixed to the arm 12A, and 13 is a roller. is there.

FIG. 4 is a front view showing the audio control head 2 of FIG. 3, in which 14 is an audio signal recording / reproducing head, 15 is a control signal recording / reproducing head, 16 is an audio signal erasing head, and 17 is a control signal. It is an erasing head. The voice signal erasing head 16 and the control signal erasing head 17 may not be attached.

Next, the operation will be described. The magnetic tape 1 is wrapped around the drum 4 and the voice control head 2 and is sent in the direction of the arrow by the capstan 4 and the pinch roller 5 to run.

[0005]

[Problems to be solved by the device]

 Since the conventional magnetic recording / reproducing apparatus is configured as described above, a difference in the tension in the width direction of the magnetic tape 1 is caused due to an error in the accuracy of each roller in the running system and the fixed guide, and the slack in either the upper or lower direction. However, there is a problem in that the contact of the magnetic tape 1 with one of the audio signal recording / reproducing head 14 and the control signal recording / reproducing head 15 in the audio control head 2 becomes worse.

The present invention was made in order to solve the above-mentioned problems. Therefore, the contact of the magnetic tape to both the audio signal recording / reproducing head and the control signal recording / reproducing head of the audio control head can be made good. The purpose is to obtain a magnetic recording / reproducing apparatus.

[0007]

[Means for Solving the Problems]

 In the magnetic recording / reproducing apparatus according to the present invention, a member that comes into contact with the diamagnetic surface side of the magnetic tape is provided between the voice control head and the capstan.

[0008]

[Action]

 In this invention, the member in contact with the magnetic tape absorbs the difference in tension in the width direction of the magnetic tape to improve the contact of the tape with the voice control head.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. In FIG. 1, reference numeral 18 is a member provided between the voice control head 2 and the capstan 3 so as to come into contact with the diamagnetic surface side of the magnetic tape 1. In this embodiment, the member 18 comes into contact with the magnetic tape 1. Shows the shaft as. In FIG. 2, 19 is an arm for holding the shaft 18, 20 is a base, 21 is a pin for rotatably attaching the base 20 and the arm 19, 22 is a center line of the magnetic tape 1, and 23 is a shaft 18. This is a weight for keeping the shaft 18 substantially vertical without contacting the tape 1. In FIGS. 1 and 2, the same or corresponding parts as those of the conventional device are designated by the same reference numerals and the description thereof will be omitted.

In the running system of the magnetic recording / reproducing apparatus configured as described above, due to the difference in the tension in the width direction of the magnetic tape 1 caused by the error in the accuracy of each element of the running system, the magnetic tape 1 of the shaft 18 is changed. By changing the manner of contact with the magnetic tape 1, the difference in tension in the width direction is absorbed, and in particular, the contact of the magnetic tape 1 with the voice control head 2 is improved.

[0011]

[Effect of the device]

 As described above, according to the present invention, since the member contacting the diamagnetic surface side of the magnetic tape is provided between the voice control head and the capstan, the difference in tension in the width direction of the magnetic tape can be absorbed, and the voice can be absorbed. The effect is that good contact of the magnetic tape with the control head can be obtained.
