The present invention relates to a tape recorder that enables the auditory to confirm that a fast transfer or rewind operation is in progress.

In the conventional tape recorder, when the fast feed operation member and the rewind operation member are operated alone, the reproducing head is configured to be separated from the tape.

Therefore, in order to confirm that the fast transfer or rewind operation is in progress, it is necessary to visually check the fast transfer operation member or the rewind operation member or visually check the reel rotation state.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a tape recorder capable of confirming through hearing that a fast transfer or rewind operation is in progress.

In order to achieve the above object, the tape recorder of the present invention includes a head moving mechanism for moving a tape from a non-operational position separated from the tape to a predetermined tape regeneration position by a regeneration operation, and a constant speed transfer by a regeneration operation. A tape recorder comprising: a constant speed feed mechanism; and a high speed feed mechanism for fast feeding the tape by a fast feed or rewind operation; wherein the magnetic head is moved in the non-operation position by the fast feed or rewind operation. And a fast forward / rewind operation head moving mechanism for moving to a tape mirror contact position between the position and the tape regeneration position.

When the fast forwarding or rewinding operation is performed, the playhead is in light contact with the tape to generate sound, so that it can be confirmed by hearing that the fast forwarding or rewinding operation is in progress.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

1 is a plan view of the tape recorder of the present invention, FIG. 2 is a bottom view of the tape recorder, and FIG. 3 is a perspective view of the bottom view of the tape recorder. In each drawing, 1 is a substrate, and a pair of reel shafts 2, 3, and one The capstan 4 and one pinch roller 5 in contact with the capstan 4 were disposed to rotate. This pinch roller 5 was rotatably mounted on the pinch roller arm 6, and this pinch roller arm 6 was rotatably mounted on the upper surface of the board | substrate 1. As shown in FIG. The pinch roller arm 6 is supported by the engagement spring (torsion spring) 7 at the position where the pinch roller 5 is separated from the capstan 4, ie, the position rotated counterclockwise in FIG.

On the upper surface of the board | substrate 1, the head mounting plate 8 is attached in the direction of arrow A, B in FIG. 1 freely. On the upper surface of the head mounting plate 8, a magnetic head 9 for recording and reproducing is mounted. This magnetic head 9 is reciprocated integrally with the head mounting plate 8, and is folded to the tape in the tape cassette not shown. The head mounting plate 8 is a direction in which the magnetic head 9 is separated from the tape by the engagement spring 7 'of the pinch roller arm 6 and an integral return spring 7' (in the direction of arrow A in FIG. 1). In addition to. The head mounting plate 8 is interlocked with the regeneration operation member 10. That is, by pressing this regeneration operation member 10 in the direction of arrow B, the press piece 10a shown in FIG. 2 presses the to-be-pressed part 24b of the moving plate 24 mentioned later, and this moving plate ( 24 moves in the direction of arrow B to move the head mounting plate 8 in the direction of arrow B via the connecting spring 25, and when the magnetic head 9 reaches the regeneration position, the position at which the magnetic head 9 is in contact with the tape, playback is performed. The operation member 10 is held at the operation position by a locking member not shown.

The head moving mechanism is constituted by the head mounting plate 8, the regeneration operation member 10, the moving plate 24, and the connecting spring 25, and the magnetic head 9 is predetermined at the non-operation position by the regeneration operation. To move the tape playback position. As the head mounting plate 8 moves to the regeneration position, the pinch roller arm 6 is pushed by the engagement spring 7 and rotated clockwise in FIG. 1 to press the pinch roller 5 to the capstan 4. Moreover, as the head mounting plate 8 moves to the regeneration position, the constant speed gear 12 in which the rotating plate 11 is rotatably supported in FIG. 1 around the capstan 4 is one side (right in FIG. 1). The gear 13 of the reel shaft (3). The constant speed gear 12 is always meshed with a small-diameter gear (not shown) which rotates integrally with the capstan 4. Then, the rotational force of the motor (not shown) is transmitted to one of the reel shafts 3 via the capstan 4 constant speed gear 12 and the gear 13, and the reel shafts 3 are fixed in the counterclockwise direction in FIG. The tape is rotated so as to run at a constant speed from the other reel shaft 2 side to the one reel shaft 3 side. That is, the capstan 4, the pinch roller 5, the constant speed gear 12, and the gear 13 comprise the constant speed feed mechanism.

On the board | substrate 1, the fast-feeding operation member 14 and the rewinding operation member 15 are arrange | positioned so that a movement can be carried out in the same direction as the head mounting plate 8. The quick feed (high speed) gear 16 meshes with the gear 13 of one reel shaft 3 via the intermediate gear 17 by pressing the quick feed operation member 14 in the arrow B direction. The quick feed gear 16 was rotatably supported by the pivoting arm 18 pivotally mounted on the lower surface of the substrate 1. The quick transfer gear 16 is connected to the pleats 19 which are integrally rotated coaxially and the pleats 21 which are integrally rotated coaxially with the capstan 4 via the endless belt 20.

The rotation of the motor is transmitted to the fast transfer gear 16 via the capstan 4, the fleece 21, the endless belt 20, and the fleece 19. Then, when the quick feed operation member 14 is press-fitted in the direction of arrow B, the quick feed gear 16 meshes with the gear 13 of one reel shaft 3 via the intermediate gear 17, and the reel shaft ( 3) is rotated at a high speed in the counterclockwise direction in FIG. 1, so that the tape travels at high speed (fast transfer) from the other reel shaft 2 side to the one reel shaft 3 side.

In addition, when the rewinding operation member 15 is press-fitted in the direction of arrow B, the fast transfer gear 16 meshes with the gear 23 of the other reel shaft 2 so that the reel shaft 2 is clockwise in the first direction. By rotating at high speed, the tape is driven (rewinded) at high speed from one reel shaft 3 side to the other reel shaft 2 side.

In this way, the fast transfer gear 16, the intermediate gear 17, the pivot arm 18, the pulley 19, and the endless belt 20 constitute a high speed transfer mechanism.

On the lower surface of the board | substrate 1, the interlocking plate 22 which cooperates with the quick feed operation member 14 and the rewinding operation member 15 is provided reciprocally in the same direction as the head mounting plate 8. The fast feed operation member 14 and the rewind operation member 15 are reciprocally provided in the same direction as the eighth. The pressing pieces 14a and 15a were bent on the quick feed operation member 14 and the rewind operation member 15 as shown in FIG. Then, when the fast-feeding operation member 14 and the rewinding operation member 15 are press-fitted in the direction of arrow B, the pressing members 14a and 15a are moved by the gap G, and then the pressure-pressed portion of the linkage plate 22 is pressed. By pressing 22a, this interlocking plate 22 drifts to arrow B direction. On the lower surface of the board | substrate 1, the moving plate 24 which cooperates with the interlocking plate 22 is provided reciprocally in the same direction as the head mounting plate 8. The movable plate 24 is connected to the head mounting plate 8 via a connecting spring 25. And when the interlocking plate 22 moves to arrow B direction, the press piece 22b presses the to-be-pressed part 24a of the moving plate 24, and this moving plate 24 will move to arrow B direction, With this, the head mounting plate 8 moves in the direction of arrow B, and the magnetic head 9 contacts the tape. That is, the quick transfer / rewind operation head moving mechanism is constituted by the quick transfer operation member 14, the rewind operation member 15, the interlocking plate 22, and the moving plate 24, and the pressing pieces 14a, ( Due to the presence of the gap G between the 15a) and the to-be-pressed part 22a, the position of the magnetic head 9 at the time of the fast feeding or rewinding operation is determined by moving the magnetic head 9 between the non-operating position and the tape regeneration position. It was set to be in light contact with the tape.

Further, as shown in FIG. 1, the pressing protrusions 26 provided on the pressing protrusions 22 provided on the interlocking plate 22 move upward through the inside of the through hole 27 of the substrate 1 to the upper surface side. Expressed.

Then, the head mounting plate 8 moves in the direction of arrow B through the interlocking plate 22 and the moving plate 24 by press-fitting the fast moving operation member 14 and the rewinding operation member 15 in the arrow B direction. When the pressing projection 26 of the linkage plate 22 presses the press part 6a of the pinch roller arm 6, the pinch roller arm 6 rotates in the counterclockwise direction in FIG. The pinch rollers 5 are spaced apart from the capstan 4.

Moreover, in the drawing, 28 is a recording operation member, 29 is a stop operation member, 300 is a pause operation member, 31 is a return spring of the regeneration operation member 10, 32 is a quick feed operation member 14 and a rewind operation member 15. A return spring for dual use, 33 is a return spring for both the stop operating member 29 and the pause operating member 30, 34 is a return spring for the recording operation member 28, 35 is a fly foil mounted on the capstan 4 , 36 is an erasing head, 37 is a motor switch, and 38 is a return lever for pulling out and returning the head mounting plate during the operation of revue / cue.

The following describes the operation of the tape recorder having the above configuration.

[Playback Action]

In the state where the tape cassette (not shown) is attached to both reel shafts (2) and (3), the regeneration operation member 10 is pressed against the biasing force of the return springs 7 'and 31 in the direction of arrow B. Since the press piece 10a presses the to-be-pressed part 24b of the movable plate 24, the movable plate 24 moves in the direction of arrow B, and the head connected to this through the connecting spring 25 is used. The mounting plate 8 drifts in the direction of arrow B, the magnetic head 9 comes into contact with the tape, the motor switch 37 is turned on, and the motor is driven so that the capstan 4, the constant speed gear 12, and the quick feed gear (16) rotate each.

In addition, the pinch roller arm 6 is accompanied by the head mounting plate 8 to move in the direction of arrow B, and is pushed by the engagement spring 7 to rotate clockwise in FIG. 1, and the pinch roller 5 is moved to the capstan ( 4). In addition, as the head mounting plate 8 swings in the direction of arrow B, the rotating plate 11 rotates in the counterclockwise direction in FIG. 1, and the constant speed gear 12 reel shaft in one direction (right in FIG. 1). It meshes with the gear 13 of (3). As a result, one reel shaft 3 rotates at a constant speed, and the tape is driven at a constant speed from the other reel shaft 2 side to the one reel shaft 3 side, whereby a regeneration operation is performed.

[Review or Cue Action]

In such a regeneration operation state, the quick feed operation member 14 or the rewind operation member 15 is pressed against the biasing force of the return spring 32 in the direction of arrow B, so that the wax pieces 14a and 15a are pressed. The tip 38b of this return lever 38 is pressed and rotated clockwise in FIG. 3, and the pressing portion 38a pulls the head mounting plate 8 against the connecting spring 25 slightly in the A direction. Pull back. When the head mounting plate 8 is pulled back and retracted, the rotating plate 11 rotates clockwise in FIG. 1 so that the constant speed gear 12 is separated from the gear 13 of one reel shaft 3, The pinch roller arm 6 rotates in the counterclockwise direction in FIG. 1, the pinch roller 5 is separated from the capstan 4, the pivot arm 18 is rotated, and the quick feed gear 16 is rotated on one reel shaft ( The gear 13 of 3) or the gear 23 of the other reel shaft 2 is engaged, these reel shafts 2 or 3 are rotated at high speed, and the magnetic head 9 is in light contact with the tape. The tape is advanced at high speed so that the revue or cue operation is performed.

[Fast forward or rewind action]

Moreover, when the fast-feeding operation member 14 or the rewinding operation member 15 is press-fitted in the arrow B direction against the biasing force of the return spring 32 in the stationary state, the pressing pieces 14a or 15a are gaps. Since the to-be-pressed part 22a of the linkage board 22 is pressed after having moved for G minutes, this linkage board 22 moves to arrow B direction. Since the press piece 22b presses the to-be-pressed part 24a of the movable plate 24 with the movement of this interlocking plate 22, since this moving plate 24 presses the to-be-pressed part 24a, This copper plate 24 moves to arrow B direction. With the movement of this moving plate 24, the head mounting plate 8 connected to this through the connecting spring 25 is in the direction of arrow B against the force of the return springs 7 ', 31. The magnetic head 9 is brought into light contact with the tape. In addition, the pressing projection 26 of the interlocking plate 22 presses the press part 6a of the pinch roller arm 6 so that the pinch roller arm 6 rotates in the counterclockwise direction in FIG. The roller 5 is spaced apart from the capstan 4.

Therefore, since the fast forwarding operation or the rewinding operation of the tape is performed in the state where the playback is generated, the playback sound is heard, and it can be confirmed by hearing that the fast forwarding or rewinding operation is in progress.

Furthermore, in the present embodiment, the head moving mechanism for the fast feed / rewind operation is constituted by the fast feed operating member 14, the rewind operating member 15, the interlocking plate 22 and the moving plate 24. The head mounting plate is pressed directly by the fast-feeding operation member 14 and the rewinding operation member 15 to limit the amount of movement of the magnetic head 9 slightly more than the regeneration operation, and the magnetic head 9 is taped. It may be configured to allow movement to the mirror contact position.

The present invention is also applicable to a so-called reproducing machine that cannot record. Furthermore, the present invention can be applied to moving the magnetic head using electric power without pressing the operating member by hand.

As described above, the present invention provides a fast transfer / rewind operation head movement for moving the magnetic head from the non-operation position to the tape light contact position between the non-operation position and the tape playback position by a fast transfer or rewind operation. It is characterized by installing a mechanism.

Therefore, it can be confirmed by hearing that the fast forwarding or rewinding operation is in progress.
