Abstract

PURPOSE:To obtain a tape recorder being compact and inexpensive but offering the sense of high-class device by devising the titled device that an operating member is fixed by the drive of a torque delivery member, the fixing is released at a prescribed position for the torque delivery member and moved while being traced with the movement of a mobile support member thereby switching a switch intermittently. CONSTITUTION:When a tape pack 1 is loaded and goes to ejecting, operation the tape pack 1 is driven by the torque of a motor M, a torque delivery member 10 drives a moving support member 2 to eject the tape pack 1. The operating member 30 is fixed because the torque drive member 10 is driven, but when the torque delivery member 10 returns to a home position, the fixing to the operation member 30 is released. Thus, the operation member 30 is moved in following to the moving support member 2 moved to eject the tape pack 1 and the switch 32 is turned off. Thus, one switch 32 switches the power to the motor M by the loading of the tape pack and the power supply is shut off after the ejection of the tape pack is finished by the motor torque.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an ejecting device for ejecting a tape pack from a tape recorder.

[Conventional technology]

Some tape recorders are equipped with a mechanism called an eject mechanism, which ejects a pack of cassette tapes from within the tape recorder using built-in power.

An example of a conventional ejecting device is shown in the side view of FIG. The state indicated by the solid line in the same figure is the state before the tape pack 1 is inserted (the state after it is ejected). When the tape pack 1 is manually pushed in, the link plate 2 is moved around the shaft 2a.
rotates to the position indicated by the chain line, and the tape pack 1 enters the play state as indicated by the chain line. At this time, the protrusion 5 attached to the link plate 2 pushes the switch operation plate 6 in the direction of the arrow.
The first switch 6 is turned on. still.

If either the first switch 6 or the second switch 13, which will be explained later, is on, the main motor M of the tape recorder is rotating. Performance can continue in this state.

When the performance is finished, proceed to the eject operation. Normally, the eject operation starts when the eject button is pressed, the solenoid is sucked, and this acts as a trigger. That is, as shown in FIG. 3, the pin 19 fixed to the plunger of the solenoid rotates the lever 20 counterclockwise, and the gear 22 is connected to the main motor M and rotated by the gear 23. Meshing, motor M → gear 23 → gear 2
The rotational drive is transmitted in the order of 2→gear 24→cam gear 15. The rotation of the cam gear 15 causes the cam 16 to push the roller 17.

As shown in the side view of FIG. 4, the roller 17 is pivotally supported by the eject lever 10, and the eject lever 10 reciprocates as shown by the arrow. The tip 10a of the eject lever 10 pushes the roller 12 that is pivotally supported on the link plate 2,
The link plate 2 rotates about the shaft 2a from the position shown by the chain line to the position shown by the solid line. The eject lever 10 is pulled back by the spring 14, but a stopper (not shown) engages the link plate 2, and this state (the state after being ejected) is maintained. At this time, the first switch 7 is turned off by the rotation of the link plate 2. However, the second switch 13 is once turned on by the forward movement of the ejector lever IO, and turned off by the backward movement. That is, the main motor M continues to rotate until the ejecting operation is completely completed, and then stops.

[Problem that the invention seeks to solve]

In conventional tape recorder eject operations, once the main motor (built-in power) stops rotating midway through the operation, there are mechanisms that use spring force to eject the tape, but the operation is rapid and lacks a sense of luxury. In order to create a sense of luxury, it is preferable to use the main motor to drive the device until the end of the ejecting operation, which necessitates the provision of multiple switches as described above, which hinders efforts to save on the number of parts and reduce costs.

The present invention has been made to solve these problems, and provides an ejecting device for obtaining a tape recorder that is compact, inexpensive, and yet has a high-class feel.

[Means for solving problems]

The configuration of an ejecting device for a tape recorder to which the present invention is applied in order to solve the above problems will be explained with reference to FIG. 1 corresponding to an embodiment.

As shown in the figure, the tape recorder eject operation device to which the present invention is applied includes a movable support member 2 that holds a tape pack 1, and a movable support that engages with the movable support member 2 and is driven by the power of an electric motor M. Drive transmission member l that moves member 2
O, one switch 32 that turns on and off the power to the electric motor M, and an operating member 30 that engages with an on/off switching section 32a of the switch 32. The operating member 30 is connected to the drive transmission member 1
The drive transmission member 10 is fixed by the above-mentioned driven movement of the movable support member 2, and the drive transmission member 10 is released from its fixation at the fixed position and moves to be able to follow the movement of the movable support member 2, thereby switching the switch 32 on and off.

[Effect]

When the tape pack 1 is ejected (FIG. 1), the drive transmission member 10 is in the normal position and is not fixed to the operating member 30. Therefore, when the tape pack 1 is inserted and the movable support member 2 moves, the operating member 30 moves following the movement, and the switch 32 is switched to continue.

When the tape pack 1 is inserted into the ejecting state (FIG. 2), the drive transmission member 10 is driven by the power of the electric motor M and moves the movable support member 2 to eject the tape pack 1.
discharge. The operating member 30 is fixed because the drive transmitting member 10 is driven, but when the drive transmitting member 10 returns to the normal position, the fixing to the operating member 30 is released. Therefore, as the movable support member 2 moves to eject the tape pack l, the operating member 30 moves,
Switch 32 is turned off.

In this way, with one switch 32, the power to the motor M can be continued during the tape pack insertion operation, and the power can be cut off after the tape pack ejection operation using the power of the motor is completed.

Embodiments of an ejecting device for a tape recorder to which the present invention is applied will be described in detail below.

FIG. 1 is a side view of a main part of an ejecting device for a tape recorder according to the present invention in a stopped state.

FIG. 2 shows its operating state diagram. In the device shown in these figures, 1 is a tape pack, 2 is a link plate which is a movable support member, 2a is its rotation axis, 31 and 32 are pack holders,
10 is an eject lever which is a drive transmission member, 12 is a roller, 14 is a spring, 15 is a cam gear, 15a is its rotating shaft, 16 is a cam, and 17 is a roller. 30 again
3 is a switch operation plate which is an operation member; 30a and 30b are concave portions thereof; 31 is a rotation stopper; 31a is a rotation shaft thereof;
2 is a power switch for the main motor M, which is an electric motor; 32
A indicates a lever which is an on/off switching section.

The tape recorder ejecting device shown in FIGS. 1 and 2 operates as follows.

When the tape pack l is manually pushed into the repack holders 31 and 32 from the state shown in Fig. ff11, the link plate 2
rotates from the position shown by the chain line in Figure 2 to the position shown by the solid line,
Tape pack 1 enters the playing state shown by the chain line. At this time, the roller 12 attached to the link plate 2 pushes the switch operation plate 30 in the direction of the arrow, and the lever 32a moves into the recessed part 3.
When pressed to 0a, the switch 32 is turned on. This causes the main motor M of the tape recorder to rotate, and the performance continues in this state.

In this performance state (shown by solid lines in Figure 2), the switch operation board 3
The concave portion 30b of 0 is located above the rotation (S)-/P. Further, the tip end 10a of the ejector 10 is slightly separated from the roller 12. When the performance is finished, move on to the eject operation. When an eject button (not shown) is pressed, the solenoid is suctioned, which triggers the mechanism shown in FIG. 3 to start the operation. Since this mechanism has already been explained, further explanation will be omitted.

As shown in FIG. 2, the roller 17 pushed by the cam 16 pushes the eject lever 10.
When the is moved, the rotation stopper 31 rotates along the upper surface 10b and engages with the recess 30b of the switch operation plate 30 (
(shown by chain lines), thereby the switch operation plate 30 is fixed. Further, the eject lever 10 moves and the tip 10a hits and pushes the roller 12 of the link plate 2, and the link plate 2 is moved to the shaft 2.
It rotates around a from the position shown by the solid line to the position shown by the chain line. A stopper (not shown) engages the link plate 2 to maintain this state (the state after being ejected).

Thereafter, since the drive by the cam 16 is no longer performed, the eject lever 10 is pulled back by the spring 14. Then the top surface f
The push-up by ob is no longer performed, the rotation stopper 31 returns to the position indicated by the solid line, and the fixation to the switch operation plate 30 is released. The switch operation plate 30 that has been released from the fixation is attached to the spring 3
3, it moves to follow the link board 2 and hits the roller 12. This movement of the switch operation plate 30 turns off the switch 32. That is, the main motor M continues to rotate until the ejecting operation is completely completed, and then stops.

〔Effect of the invention〕

As explained above, in the tape recorder eject operation device to which the present invention is applied, the drive of the electric motor (built-in power) does not stop during the eject operation, and the tape pack is ejected by driving the electric motor until the end. Therefore, it has a more luxurious feel compared to the operation of a mechanism that uses spring force to discharge the liquid from the middle of the operation. Furthermore, only one switch is required to prevent the power to the motor from being turned off until the ejection operation is completed.

Therefore, the number of parts can be reduced, and a tape recorder that is compact, inexpensive, and yet has a high-class feel can be obtained.
