するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the invention of a fast forward/rewind operation mechanism for a tape player, which reduces the operating force for fast forward/rewind in a tape player, simplifies the mechanism, and improves operability with a small size and light weight. The purpose is to provide an excellent tape player at relatively low cost.

力が相当に重くならざるを得ない不利がある。 For tape players, it is essential to perform fast forward and rewind operations, and various types of such fast forward and rewind mechanisms have been proposed and put into practical use. However, in such a conventional tape player with a fast-forward/rewind mechanism, when performing fast-forward/rewind, the pinch roller, idler, head, etc. are automatically compressed by spring force when the cassette is inserted. In the case of a wire, it is necessary to release the pressure of the pinch roller, idler, head, etc. against the springing force, which has the disadvantage that the operating force is considerably heavy.

ものを必要とする不利を伴う。 In addition, some proposals have been made regarding the use of electromagnetic plungers in order to reduce such operating force, but it is possible to instantly remove the pinch rollers, idlers, heads, and other members mentioned above from the crimped state. In order to perform the release operation and release the locked state, a considerably strong plunger operating force is required, and the operating stroke must also be large, so a correspondingly large electromagnetic plunger is required. It also has the disadvantage of requiring a large capacity circuit configuration.

を有している。 Furthermore, when fast forwarding or rewinding as described above is performed, the respective fast forwarding or rewinding state must be canceled after the fast forwarding or rewinding is completed, and for this reason, during such fast forwarding or rewinding, it is necessary to wait until the operation is completed. This has the disadvantage that the release operation must be performed first before the release operation or the subsequent start of use.

も平易化するようにしたものである。 The present invention was devised after repeated studies in view of the above-mentioned actual situation, and uses an intermittent gear driven by a motor to control the crimping and release of each member such as the above-mentioned pinch roller,
activating the control member against the biasing force in the direction of releasing the spring, locking it by respective locking means, and releasing the locking means by a control member interlocked with the fast forward/rewind operation; By calling in the intermittent gear mentioned above in response to the tape end detection signal in the fast forward/rewind state and releasing the lock on the fast forward or rewind lever, the disadvantages described above can be appropriately resolved, the operability is excellent, and the mechanism is improved. The device is designed to be simple, small and lightweight, and to reduce costs.Furthermore, an electromagnetic plunger is used as the locking means, and a sensing member is actuated during a fast forward/rewind operation, so that the electromagnetic plunger is energized accordingly. The unlocking operation of the locking means is also simplified by turning it off using the sensing member.

せて中間位置に復帰させる。 The above-mentioned flywheel 1R and the other flywheel 1F installed opposite to it have opposite rotational directions, as is clear from the state in which the belt 4 is suspended from the motor pulley as shown in FIG.
First and second reel bases 25R and 25F are provided for these flywheels 1R and 1F, respectively, and a gear idler is provided between these reel bases 25R and 25F on the free end side of the interlocking member 36. 37 is located, and the idler 37 is moved to the flywheel 1 by the operation of the interlocking member 36.
R or 1F circumferential gear part 38 and reel base 25
R and 25F are simultaneously engaged and disengaged from the circumferential gears, thereby performing fast forwarding or rewinding operations, but the idler 37 is engaged with the flywheel and reel base first with a slight time difference. The peripheral speed gear portion 38 of the flywheel is engaged first, and then the reel base gear portion is engaged. That is, by doing this, the idler 37 first rotates, and under that rotation condition, it engages with the stopped reel base to perform accurate rotation, and the idler 37 and the reel base, which are still stopped, are rotated. This avoids the formation of a non-rotatable state between the tips of these gears. On the front of the deck 100, there are two operating levers 3 on both sides of the release lever 33 for fast forwarding or rewinding.
1 and 32 (these operation levers can be used for fast forwarding or rewinding depending on the running direction of the tape, and their display is generally just an arrow indicating the running direction), and these fast forwarding The rewinding levers 31 and 32 are each provided with a spring 40 and are always biased in the release direction, but each of the operating levers 31 and 32 has an operating section 31 inside thereof.
a, 32a are provided oppositely, and the operation parts 31a, 3
A swinging member 34 is rotatably provided between 2a with a pivot 34a, and the swinging member 34 has passive parts 34b and 34 for the operating parts 31a and 32a as described above.
b, 34c, and 34c are provided opposite to each other on the back side and the front side, respectively, and when either of the operation levers 31 or 32 is pushed forward, it acts on either of the passive parts 34b and causes the swinging member 34 to move. The swing member 34 is configured to swing and tilt, and its back movement acts on one of the passive parts 34c to restrict the swing member 34 from moving back to the neutral state shown in the figure. Swinging member 34 and the interlocking member 36
A U-shaped linear elastic member 41 is provided between the protrusion 34d provided on the tip side of the swinging member 34.
The elastic member 41 is attached in a clamping manner to the pivot 36a of the interlocking member 36 and the projection 36b provided on the distal end thereof, so that the swinging member 34 as described above cannot be swung. When moving, the interlocking member 3
6 is symmetrically tilted and moved back, but the tilting angle of the interlocking member 36 is limited by the locking claws 42a and 42b provided on both sides of the interlocking member 36, thereby preventing the above-mentioned idler gear 37 from locking. adapt to the situation. Note that these locking claws 42a, 42b are bent and adjusted as appropriate to adjust their restriction state appropriately. The linear elastic material 41 provides an appropriate cushioning effect when the idler gear 37 engages with each gear portion of the flywheel and reel base, that is, prevents damage to the gear tooth tips when engaged as a rigid body, and also The gears are engaged with an action force that suppresses vibrations caused by the rotational operation and overcomes the repulsive force when the rotated gears engage with each other, and when disengaging the engagement, the interlocking member 36 is interlocked with the swinging member 34, and the intermediate return to position.

When the operating end 5p of the intermittent gear 2 is engaged with the protrusion 17 of the intermittent gear 2 to stop its operation, the locking member 5 is moved to the operating section 5a by inserting a cassette, detecting the tape end, or switching a program. On the other hand, when the spring 5s is operated against the action of the spring 5s, the locking between the operating end 5p and the locking protrusion 17 is released. As a result of this unlocking, the force exerted by the spring 6 acts on the stepped portion 3a of the cam portion 3 via the latch 8 of the actuating member 7, so that the intermittent gear 2 is slightly rotated counterclockwise in FIG. The retainer 8 of 7 is dropped into the deepest part of the cam part 3 from the state where it is engaged with the intermediate part as shown. As shown in the figure, in the process in which the retainer 8 is dropped into the deepest part of the cam part 3, an arcuate part 3a' is formed between the intermediate part of the stepped part 3a and the deepest part of the cam part 3. , therefore the cam part 3 is the ninth
Even if it is rotated counterclockwise from the state shown in the figure, the pressing force of the retainer 8 (due to the spring 6) that acts in the horizontal direction in this diagram acts almost equally as a pressing rotational force on the step portion 3a (if the flat If the stepped portion 3a is such that the rotational force of the retainer 8 that presses the cam portion 3 is rapidly reduced by the rotation of the cam portion 3)
It can be in the state shown in the figure. In this way, the cam part 3

Therefore, the pin 10a of the cam switching member 10 reaches the bent corner of the J-shaped engagement hole 7e formed at the top of the actuating member 7, but in the state shown in FIGS. The stepped portion 12e is connected to the engagement hole 7.
Pin 10a covers the bent part of e.
is not dropped into the bent portion even by the action of the spring 10s, that is, when the control member 12 is retracted as shown in FIGS. The member 10 is the actuating member 7
It cannot be activated by. Furthermore, in the process from the state shown in FIG. 9 to the state shown in FIG.
b is in a state where it is detached from the passive edge 12e of the control member 12, and therefore, the actuating member 7 is further moved slightly forward by the cam portion 3 (the actuating member when the retainer 8 is dropped into the deepest part of the cam portion 3). The control member 12 is not actuated until the locking member 15b comes into contact with the passive edge 12e again (in the opposite direction to the sliding direction of the actuating member 7). There will be a slight delay.
