Abstract

PURPOSE:To record/reproduce stable audio signals by providing the magnetic recording/reproducing device with a pad for pressing and sticking a magnetic recording medium fast to an audio head. CONSTITUTION:The pad assembly 1 is arranged oppositely to the audio head through a tape 14. When the tape 14 is loaded, the pad assembly 1 is rotated in the clockwise direction through a rotary spindle and the tape 14 is pressed and stuck fast to the head 2. Consequently, an audio signal can stably be recorded and reproduced without mixing noise generated due to the oscillation of the tape 14.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a magnetic recording and reproducing device configured to record and reproduce audio signals on a recording medium, such as a video tape recorder. .

[Prior Art] Fig. 3 is a schematic diagram showing a tape reproducing state of a conventional magnetic recording/reproducing device. (0 is a capstan shaft that rotates to run the tape (14), (3) is a capstan shaft with the tape (14) sandwiched between it and the capstan shaft (4). This is a pinch roller that transmits the rotational force of the stun shaft (4) to the tape (10).

(5) is a tension control bin for adjusting the tension when rewinding the tape, (6) is a video cassette that stores the tape (14), and the supply reel (15) and take-up reel ( 16). (7) is a tension control pin that adjusts the tension when feeding the tape, (8)
is an inopedance roller to absorb tape vibration,
(8) is a rotating drum on which a rotating head (not shown) such as a video head and a high-fidelity head is mounted.

Next, the operation of the above configuration will be explained.

Video power M! -/ The tape (14) pulled out from the gate (8) is run at a constant speed by the capstan shaft (0) and the pinch roller (3). At this time.

A constant tension is applied to the drum (Ill) and the audio head (2) by a tension control pin (7). Information is recorded and played back from the drum (8) to the ten-go (14) via the video head and hi-fi head, and the audio head (2) records audio signals on the tape (14) and records the above-mentioned signals. read out.

In addition, during fast forwarding or winding, the capstan shaft (4) and pinch roller (3) are separated and the tape is rolled at high speed.
14) runs. During fast forwarding, the tension control bin (
7) works, and the tension control bin (
5) comes into play.

[Problems to be Solved by the Invention] Since the conventional magnetic recording and reproducing apparatus is configured as described above, vibrations are applied to the tape through the drum rotating at high speed during recording and reproducing.

There have been problems in that the audio head does not make stable contact with the tape, and noise in the 0T listening frequency band is mixed into the audio signal, making it impossible to perform stable recording and playback.

This invention was made in order to solve the above-mentioned problems.It is an object of the present invention to stably keep the tape in close contact with the audio head during tape running, and to stably record and reproduce a predetermined audio signal without introducing noise. The purpose of the present invention is to provide a magnetic recording/reproducing device that can perform the following functions.

[Means for Solving the Problems] A magnetic recording and reproducing device according to the present invention is characterized in that it includes a pad that presses a tape into close contact with an audio head.

[Function] According to this invention, it is possible to press the tape to the audio pad through the pad and bring it into stable contact with the pad during recording and playback, so that the audio signal is not mixed in with noise due to tape vibration. can be recorded and played back stably.

[Embodiment of the Invention] Hereinafter, an embodiment of the present invention will be described based on the drawings.

FIG. 1 is a schematic diagram showing a tape reproducing state of a magnetic recording and reproducing apparatus according to an embodiment of the present invention.
2) to (8) and (E4) to (18) are the same as the conventional example shown in 3rd FgJ, so the same reference numerals are given to the corresponding parts and detailed explanation thereof will be omitted.

In Fig. 1, (1) is a pad assembly, and an audio head (2) is placed across the running path of the tape (14).
is placed opposite.

FIG. 2 is a perspective view showing the detailed structure of the pad assembly (1). In the same figure, (11) is a part holder, and (12) is a pad holder (11) that is rotated clockwise (arrow X). and a rotating shaft for rotating approximately 90 degrees counterclockwise (arrow y), (13) is a tape (14
) is an example of a pad for pressing the audio head (2) into close contact with the pad holder (1).
1) is attached.

Next, the operation of the above configuration will be explained.

When the tape (14) is loaded as shown in FIG. 1, the pad assembly (1) is rotated clockwise (x) via the rotating shaft (12), as shown in FIG. 2(a). Then, the tape (14) is pressed against the audio head (2) by the felt (13) and brought into close contact with the audio head (2). When the tape (14) is run in this state, even if vibrations are applied to the tape (14) via the rotating drum (9), the tape (14) will not be able to move between the audio head (2) and the pad assembly. Since the tape is sandwiched between the felt (13) of (1) and does not generate vibrations, in other words, the tape stably contacts the audio tape (2), stable audio signal recording and playback is possible. Can be done. In addition, the contact between the tape (14) and the audio head (2) can be maintained stably even if the tape tension is weakened by the tension control pin (5), C7), resulting in stable recording and playback of audio signals. There is little deterioration.

Also, when fast forwarding or winding the tape (14) into the video cassette (6), as shown in FIG. 2(b),
The pad assembly (1) is rotated counterclockwise via the rotating shaft (12) to free the tape (10°).
Allows for smooth fast forwarding and winding.

In addition, in the above embodiment, the pad assembly (1) was configured to be rotated via the rotation shaft (12), but the felt (13) of the pad assembly (1) was rotated using the plunger. It may be configured to be pressed.

In addition, in the above embodiment, felt was used as the pad, but if it has elasticity and does not interfere with the tape (14),
Pads made of other constituent materials may be used.No. [Effects of the Invention] As described above, according to the present invention, since the tape is always pressed and attached to the audio head,
In addition to being able to record and play stable audio signals without being affected by tape vibration,
Since the tape tension can be weakened, tape damage can be reduced.
