To remove the cassette from the playing position, move the head chassis backwards,
It is necessary to move the cassette lever and cassette holder from the playing position to the insertion and pop-out position, and to flip out the cassette. The conventional method of performing these operations manually has the disadvantage that the button for ejecting the cassette must be pressed with a relatively large force and with a relatively large stroke.

歯車列が必須である。 Recently, a system that uses the power of a performance motor to eject a cassette has appeared.
(For example, JP-A-57-123562 or JP-A-59
(Refer to Publication No. 82656) In these systems, the actuating lever that drives the cassette ejecting mechanism member is driven by a performance motor to cause the cassette to eject. In order to prevent the driving force from being transmitted to the operating lever, a gear train that constitutes the clutch mechanism and the reduction mechanism is essential.

Since the gear train of the clutch mechanism was constructed in the low-speed part after deceleration, the force required to engage and disengage was large, and it could become inoperable unless a high-torque motor was used, which led to the need for a larger motor. However, this has led to problems such as high manufacturing costs.

し位置に保持される。 Next, a cassette ejecting lever 12 and an upper ejecting lever 13 that rotates in the same manner as the cassette ejecting lever 12 are integrally provided on the long shaft 07 provided on the chassis 1, and the tip 121 of the cassette ejecting lever 12 is locked. a pop-out locking lever 14 for releasing the cassette, and a cassette locking lever 15 for keeping the cassette lever 2 in the pop-out insertion position.
They are provided on the fixed shafts 0 8 and 0 9 of the chassis 1, respectively.
Also, one end 12 3 of this cassette ejection lever 12,
Connect the upper end 83 of clutch lever 8 with link 33. In the above condition, press the cassette eject button 11 provided outside the tape player with the spring 21.
When the other end 10 2 of the clutch lock lever 10 is pushed by the link 31 by about 3 mm against the force of about 100 g, the tip 8 of the clutch lever 8 of the tip 10 1 of the clutch lever 10 is pushed. 1 is unlocked and the clutch lever 8 rotates clockwise by the force of the spring 21, so the small gear 92 of the second reduction gear 9 meshes with the large gear 61 of the first reduction gear 6. ,
Therefore, the operating lever 5, which is integrated with the large gear 51 that is constantly meshing with the small gear 62 of the first reduction gear 6, is its fulcrum.
02 begins to rotate counterclockwise, and while its protrusion 52 slides on the horizontal surface 41 of the headshaft 4, the headshaft 4 resists the force of a spring (not shown) and locks the topmost lock. After the protrusion 52 is lifted to the position, the protrusion 52 is moved to the inclined cam 42 of the head chassis 4, and since this angle of inclination is made to match the direction of rotation of the protrusion 52 , the head chassis 4 is hardly lifted and this By time mentioned link 3
The play in the cassette lever 2 has also disappeared, and the rear lower end 22 of the cassette lever 2 is then pulled by the link 32, and the cassette lever 2 and therefore the cassette holder 3 are
holds the cassette C horizontally and lifts it upward, and when it reaches the top step, the rear lower end 22 of the cassette lever 2 pops out and jumps over the tip 141 of the locking lever 14, so that the tip 121 of the cassette lever 12 jumps. When the lock is released, during this time the tension spring 22 connecting the lower left end 53 of the operating lever 5 and the middle 122 of the cassette ejection lever 12 is pulled from the beginning of the rotation of the operating lever 5, and the stored force is generated. As a result, the cassette ejecting lever 12 rotates counterclockwise, and the cassette C is moved to the right by the claw 131 set at the tip of the upper ejecting lever 13, which is integrated with the cassette ejecting lever 12 . When the cassette lever 2 is ejected, the rear lower end 2 2 of the cassette lever 2 is locked to the tip 15 1 of the cassette lock lever 15 , and the cassette lever 2 and therefore the cassette holder 3 are locked.
is held at the insertion/extraction position of the cassette C against the force of the spring 23.

2 3 pulls the upper end 8 3 of the clutch lever 8 by the link 33 against the force of the spring 21, so the clutch lever 8 rotates counterclockwise and the second reduction gear 9
The small gear 92 and the large gear 61 of the first reduction gear 6 are disengaged, the operating lever 5 stops rotating, and the power is also turned off (not shown). A series of cassette ejection operations is completed.

演奏位置にもたらされる。 Next, when you want to start playing, insert the cassette C into the cassette holder 3 from the right side, the claw 131 at the tip of the upper pop-out lever 13 will be pushed, and the cassette pop-out lever 122 , which is integrated with this, will move clockwise. the middle surface 12 of the cassette ejecting lever 12.
kicks the tip 151 of the cassette lock lever 15, so the cassette lever 2 and therefore the cassette holder 3 are rotated downward by the force of the compression spring 23 provided between the chassis 1 and the rear lower end 22 of the cassette lever 2. When the cassette C is brought to the playing position, the operating lever 5, which had been free, is brought back to its initial position and the power is turned on, and the head chassis 4 is also unlocked and released by the force of a spring (not shown). is brought to the playing position.

る。(Effects of the Invention) As described above, the present invention allows the removal of a cassette to be
Using an extremely simple and rational mechanism, this operation is performed using the power of the cassette playing motor, so the operating force for the cassette eject button can be reduced to, for example,
It can be made extremely small, weighing less than 100 grams and with a stroke of less than 3 mm. In particular, in the present invention, the cassette ejecting operation part, that is, the action part of the clutch mechanism, is performed at a high speed, ie, low torque part, so that the engagement and disengagement of the gears can be carried out lightly and without strain. In particular, it does not require a high-torque motor and has the advantage of low manufacturing costs.

テーププレイヤーのカセツト跳出し機構。1. A cassette lever and a cassette holder are provided on the chassis so as to be rotatable between the playing position and the insertion/jumping position, and a head chassis is provided so as to be movable forward and backward with respect to the cassette in the playing position, and an operating lever for operating the cassette lever and the head chassis is provided. , a first reduction gear that is rotatably mounted on a fixed shaft of the chassis, and has a large gear centered on its rotation fulcrum on one side of the operating lever, and a small gear and a large gear that are constantly meshed with the large gear. The gear is installed on the fixed shaft of the chassis, and the pulley installed on the fixed shaft of the chassis is always driven by the motor and belt during performance, and the clutch lever is rotated on the same extension axis as the pulley shaft. A second reduction gear is provided on the shaft attached to the clutch lever, and the large gear of the second reduction gear is always in mesh with the small gear integrated with the pulley. A clutch lock lever is provided on the fixed shaft of the chassis for biasing the small gear of the second reduction gear in a direction in which it meshes with the large gear of the first reduction gear and for preventing movement of the clutch lever in the biasing direction, and is provided with a protrusion, and the head chassis is provided with a horizontal part on which this protrusion comes into contact and moves, and a cam part that is tilted in the direction of movement of the protrusion. The lower end is connected with a link with some play, and the head chassis is brought to the retracted position by the rotation of the operating lever.
A cassette ejecting lever is rotatably provided which operates in a direction to eject the cassette due to the bias of a spring when the cassette lever is lifted to the cassette ejecting insertion position, and between the cassette ejecting lever and the clutch lever. A cassette type tape player, characterized in that a link is connected for rotating the clutch lever in conjunction with the operation of the cassette ejecting lever to disengage the first reduction gear and the second reduction gear. Cassette ejection mechanism.
