Abstract

PURPOSE:To attain effective ejecting operation in accordance with conditions by executing the ejecting operation automtically by an intermittent gear to be driven intermittently by a motor and by executing the ejecting operation properly also manually. CONSTITUTION:When electric power is supplied to a plunger 63, a stopper member 62 is actuated, the engagement of a projected part 1b of the intermittent gear 1 with a leading end part 62b is released, the intermittent gear 1 is rotated as shown by an arrow A by a gear 52, a follower 4 of a switching member 5 is presed in the direction of an arrow B by a cam part 2 of the intermittent gear 1, and a joiner 6b of an operation link 6 is rotated in the direction of an arrow C through the switching member 5. Under the condition that the other hand of an ejecting link 7 is pressed by a joiner 8b of a lock arm 8, the ejecting link 7 is pressed forward, and when the joiner 6b reaches the position shown by a false line, an ejecting lever 9 is forwarded as shown by an arrow D to execute the ejecting operation by an opertion part 9a. When a manual ejecting lever 16 is depressed, the ejecting lever 9 is pushed in through a locking part 16b to actuate the ejecting means.

Description

DETAILED DESCRIPTION OF THE INVENTION By inventing a manual and auto-eject mechanism in a tape bank, the present invention allows the automatic eject operation in the tape bank to be performed appropriately, and also allows the manual operation to be performed appropriately, thereby eliminating the need for an angular mechanism. This is what we are trying to provide.

Ejecting the tape bank is essential for its use, and it has become increasingly common to perform such ejecting automatically using the rotational force of a motor. It is becoming more and more popular.

In other words, instead of performing the operations using the conventional fingertip operation, each switching operation is performed using a light operation called a feather touch, which has the advantage of greatly simplifying the operation. .

By the way, even though automatic ejecting operation like this is advantageous in use, it is essential to be connected to a power source in order to obtain this operation, and there is no need to worry about inserting and removing tape punctures. It is preferable that this can be carried out appropriately even when the MIY source is not connected.

For example, when it is simply displayed in a store, or during the installation process at the central location in a car, or the installation is done later (V), the power supply is not connected when the car's engine key is turned off. It is necessary to consider and adjust the situation (or to replace or remove the tape bank that is still inserted. If the tape bank is automatically ejected as described above, it is necessary to There is a disadvantage in that it is difficult to operate at all, and automation at all costs is actually inconvenient.

The present invention has been researched and devised to eliminate the disadvantages of the conventional ones as described above, and to explain its practical aspect as shown in the attached drawings, the overall structure of the tape bank will be described. is as shown in FIG.

A Sunzi 13 is attached, and the Sunzi 13 is engaged with an L-shaped lock hole 14 drilled in the machine base 50, and the locking portion 12 of the long coupling L'-M2 as described in 1.
The free end side of the spring 11, which is an elastic switching member whose base end is locked to the head plate 10 and is attached by the shaft portion 10a, is shown in the space a. An eject operating portion 9a is formed on one side of the eject lever 9 as described above, and an extending portion 9b is formed on the other side. The locking part 16b formed at one end of the manual eject lever 16 is a joint part 9 of the eject lever 9.
c, and when the manual eject lever 16 is pressed, the eject lever 9 is also operated, but when the eject lever 9 is activated as described later, the manual eject lever 16 is maintained in an inoperative state. It is designed to be done. Each eject lever 9, 16 is provided with a return spring 20, and an eject operating portion 16a is formed on the other side of the manual eject lever 16 to face the operating portion 9a. To explain the operation of the device according to the present invention as described above, a power switch is provided facing the tape cutting/charging castle as is known in the art.
By inserting the cassette into the plano jar 63 and actuating the stopper member 62, one thread protrusion 1b and the tip end 62b are connected.
The locking of the cam part 20 is completely released, and the cam part 2 is moved by the pressing force of the spring acting on the switching member 5 of the follower 4 joined to the stepped part 2a of the cam part 20.
The intermittent gear 1 is rotated to engage the gear 52 driven by the motor, and the cam portion 2 is automatically rotated. By sliding the switching member 5 to the left in the figure, the sector member 2B is rotated to move the Sun Tzu 31 upward from the F ten of the inclined portion 24 where it had been engaged until then. By setting the state as shown in FIG. 1, the control piece 22 can be rotated clockwise, and the locking member 32 and the holding member 36 are moved to the right in the figure by the tensile force of the spring 41, and the holding plunger 40 is energized. is absorbed and retained. - The follower 4, which has once fallen into the bottom of the cam part 2 via the bulged part 2b, will reversely slide the switching member 5 to the right in the figure by two subsequent rotations of the cam part.
Thereby, the Sunzi 31 of the sector member 28 is moved downward and the inclined part 24 of the fljlJ piece 22 is pushed downward,
From the state in which the bottle 6T of the head plate 10 was in contact with the F end of the long hole 68, the head plate 10 is pushed downward until it touches the upper end of the long hole 68 as shown in FIG. Press them together to form a regenerated state. Note that the locking member 32 is rotated in the direction of the occlusal bar 1 when the Sun Tzu 34 is pushed by the inclined portion 25 against the spring 38, and the follower 4 remains locked even after the head plate 10 advances to the playback position as described above. , the control piece 22 is continuously pushed downward until it reaches the highest point of the fulcrum 23.
moves downward in the rectangular hole 21 against the tensile force of the spring 27 [7, the locking member 32 has its grandchild 34 disengaged above the inclined portion 25, and the lock member 32 moves to the locking stage as shown in the figure by the tensile force of the spring 38. 26
It is in a state where it is engaged. Furthermore, from this state, when the follower 4 exceeds the highest point of the cam portion 2, the intermittent gear 1
Under the condition that the plunger 630 is disengaged from the gear 2 at point a and the plunger 630 is de-energized, the tip 62b of the stopper part 62 is returned to the stop position by the spring 64, and the intermittent gear 10 rotations are adjusted to the correct gear. 52, it will be stopped at the opposite position j1, and -10,000 switching member 5 side 13 article 16
The follower 4 engages with the stepped portion 2a by being biased to the left in the drawing by the tensile force of In the released control piece 22, the inclined part 26 is connected to the locking part 320 and the locking part 34.
The spring 27 moves upward as shown in the figure until it comes into contact with the spring 27, and
This state is maintained by the holding force of the holding plunger 40 and the tensile force of the spring 38 as shown in FIG.

When the plunger 63 is further operated in the regenerating state shown in FIG. Rotate the connector 6b of the operating lever 6 in the direction of arrow C through the lever, and push the ejector T under the condition that the other side of the ejector 7 is held down by the connector 8b of the Ronfirm 8, When the connector 6b reaches the position shown by the imaginary line in FIG. 1, the eject lever 9 is moved to the first position.
The eject lever 9 is moved forward in the direction of the arrow shown in FIG. It is as follows.

The operational relationship when the manual eject mechanism 16 is pushed is as shown in FIG.
After the ejecting operation is completed, both ejecting levers 9.16 are ejected by the action of the springs 20, 20.

According to the present invention as described above, the ejecting operation can be performed automatically with a simple operation using the intermittent gear driven intermittently by the motor, and the ejecting operation can also be performed manually as appropriate. Even in such situations, effective ejection can be carried out in response to each situation, and such a tape player can be used and handled appropriately, so it is an industrially effective invention.
