Abstract

PURPOSE:To aurally confirm that a tape recorder is in the midst of fast forwarding or rewinding action by moving a magnetic head from a non-acting position to a position lying between the non-acting position and a reproducing position where the head slightly contacts a tape. CONSTITUTION:By pushing a fast forwarding operation member14 or a rewinding operation member 15 in a direction shown by an arrow B from a stopping state, a pressing piece 14a or 15a moves by as long as a gap G to press a pat to be pressed 22a and an interlocking plate 22 moves in the direction shown by the arrow B. Then, a pressing piece 22b presses a part to be pressed 24a and a moving plate 24 moves in the direction shown by the arrow B. A head mounting plate 8 moves in the direction shown by the arrow B and the magnetic head 9 slightly comes in contact with a tape. When the pressing projection 26 of the interlocking plate 22 presses a part to be pressed 6a, a pinch roller arm 6 turns and a pinch roller 5 separates from a capstan 4 to be in a state where a reproduced sound is generated. Thus, it can be aurally confirmed that the tape recorder is in the midst of the fast forwarding or rewinding action.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a tape recorder that allows a listener to confirm whether fast-forwarding or rewinding is in progress.

(Prior Art) In a conventional tape recorder, the playback head is separated from the tape when the fast-forward operation member and the rewind operation member are operated independently.

(Problem to be Solved by the Invention) Therefore, in order to confirm that fast forwarding or rewinding is in progress, it is necessary to visually check whether the fast forwarding or rewinding operation is in progress, by looking at the fast forwarding operating member or rewinding operating member, or by observing the rotating state of the reel. I have to check.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a tape recorder in which it is possible to audibly confirm whether fast-forwarding or rewinding is in progress.

(Means for Solving the Problems) In order to achieve the above object, the tape recorder of the present invention includes a head moving mechanism that moves the magnetic head from a non-operating position away from the tape to a predetermined tape playback position by a playback operation, and a playback In a tape recorder, the tape recorder is equipped with a constant speed feed mechanism that feeds the tape at a constant speed when operated, and a high speed feed mechanism that feeds the tape at high speed when the fast forward or rewind operation is performed. The present invention is characterized in that a head moving mechanism for fast forwarding/rewinding operations is provided for moving the head from the position to a tape light contact position located between the non-operating position and the tape reproducing position.

(Function) When a fast-forward or rewind operation is performed, the playback head makes light contact with the tape and generates a sound, so that it can be audibly confirmed that the fast-forward or rewind operation is in progress.

(Example) Hereinafter, one example of the present invention will be described based on the drawings. 1st

A pair of reel shafts 2 and 3, a capstan 4, and a pinch roller 5 that contacts the capstan 4 are rotatably disposed on its upper surface. This pinch roller 5 is rotatably mounted on the pinch roller arm 6]
The pinch roller arm 6 is rotatably mounted on the upper surface of the substrate 1. Pinch roller arm 6
is held by an engagement spring (torsion spring) 7 at a position where the pinch roller 5 is separated from the cab stun 4, that is, at a position rotated counterclockwise in the M1 direction in FIG.

On the top surface of the board 1, a head access plate 8 is provided as indicated by arrows A and B in FIG.
It is mounted so that it can move freely in both directions. A magnetic head 9 for recording and reproduction is attached to the upper surface of the head mounting plate 8. The magnetic head 9 moves toward and away from a tape in a tape cassette (not shown) by reciprocating together with the head mounting plate 8. The head retainer 4 = J plate 8 is operated in the direction in which the magnetic head 9 is separated from the tape (
It is observed in the eight directions of arrows in Figure 1). The head mounting plate 8 is interlocked with the reproduction operation member 10. That is, by pushing the regeneration operation member 10 in the direction of arrow B, the suppressing piece 10a shown in FIG. Connect the head mounting plate 8 via the connecting spring 25 in the direction of arrow B.
When the magnetic head 9 reaches the playback position where the magnetic head 9 contacts the tape, the playback operation member 10 is held at the operation position by a locking member (not shown). The head mounting plate 8, playback operation member 10, moving plate 24, and connection spring 25 constitute a head movement mechanism, and the magnetic head 9 is moved from a non-operating position to a predetermined tape playback position by a playback operation. There is. Head mounting plate 8

The pinch roller 5 is brought into pressure contact with the capstan 4.

Additionally, as the head pickup plate 8 moves to the playback position,
A rotary plate l1 rotates counterclockwise in FIG. 1 around the capstan 4, and a constant speed gear 12 rotatably supported by the rotary plate 11 rotates on one side (right side in FIG. 1). It meshes with the gal 13 of the reel shaft 3. The constant speed gear 12 is constantly engaged with a small diameter gear (not shown) that rotates integrally with the capstan 4.

The rotational force of the motor (not shown) is applied to the capstan 4,
The force is transmitted to one reel shaft 3 via constant speed gals 12 and 13, and this reel shaft 3 is rotated at a constant speed in the counterclockwise direction in FIG. The reel is run at a constant speed on the reel shaft 3 side.

That is, capstan 4, pinch roller 5, constant speed gal 12
and gal 13 constitute a constant speed feeding mechanism.

A fast forward operation member 14 and a rewind operation member l5 are disposed on the substrate 1 so as to be movable in the same direction as the head mounting plate 8. By pushing the fast-feeding operation member 14 in the direction of arrow B, the fast-feeding (high-speed) gal l6 meshes with the gal l3 of one reel shaft 3 via the intermediate gal l7. The fast-forwarding gear 16 is rotatably supported by a rotating arm 18 rotatably attached to the lower surface of the substrate 1. fast forward gya 1

Then, when the fast forward operation member 14 and the rewind operation member 15 are pushed in the direction of arrow B, these pressing pieces 14a and 15a move by the gap G, and then press the pressed portion 22a of the interlocking plate 22, thereby causing this interlocking operation. The plate 22 moves forward in the direction of arrow B.

A moving plate 24 that interlocks with the interlocking plate 22 is provided on the lower surface of the substrate 1 so as to be able to reciprocate in the same direction as the head mounting plate 8. This moving plate 24 is connected to the head holding plate 8 via a connecting spring 25. Then, when the interlocking plate 22 moves in the direction of arrow B, the pressing piece 22b moves against the moving plate 22.
By pressing the pressed portion 24a of the moving plate 2

(Fast forward or rewind operation) Also, when the fast forward operation member 14 or the rewind operation member 15 is pushed in the direction of arrow B against the biasing force of the return spring 32 from a stopped state, the pressing pieces 14a or 15a are pushed into the gap. After moving by G, the pressed portion 2 of the interlocking plate 22
In order to press 2a, this interlocking plate 22 moves in the direction of arrow B. As the interlocking plate 22 moves, the suppression piece 22
b presses the pressed portion 24a of the movable plate 24, so the movable plate 24 moves in the direction of arrow B. As the moving plate 24 moves, the head mounting plate 8, which is connected to the moving plate 24 via the connecting spring 25, moves in the direction of arrow B against the urging force of the return springs 7' and 31, and the magnetic The head 9 makes light contact with the tape. Further, as the pressing protrusion 26 of the interlocking plate 22 presses the pressed portion 6a of the pinch roller arm 6, the pinch roller arm 6 rotates counterclockwise in FIG. distance from. Therefore,
The tape is fast-forwarded or rewinded while the playback sound is being generated, and by listening to the playback sound, it can be audibly confirmed that the fast-forwarding or rewinding operation is in progress.

In this embodiment, the head moving mechanism for fast forwarding/rewinding operation is constituted by the fast forwarding operation member 14, the rewinding operation member 15, the interlocking plate 22, and the moving plate 24, but the present invention is not limited to this. Instead, the fast-forward operation member 14 and the rewind operation member 15 directly press the head removal {= J plate to limit the amount of movement of the magnetic head 9 slightly more than during playback operation, and bring the magnetic head 9 into light contact with the tape. It may be configured to move to a certain position.

In addition, the present invention does not allow recording, so-called 4. It is also applicable to raw-only machines. Furthermore, it is also applicable to a device in which the magnetic head is moved using electrical power without manually pushing the operating member.
