Description

Switch devices for loading cassette tape players for cars

The present invention relates to a deck of a cassette tape player for an automobile, and in particular, the cassette tape is automatically loaded when the cassette tape is inserted to a certain depth rather than the artificial force of inserting and removing the cassette tape. It is intended to be discharged.

In general, a conventional cassette tape player for automobiles is loaded by inserting the cassette tape, but it must be pushed by artificial force until the cassette tape is completely inserted, and when ejecting, the eject knob is pushed by force until the cassette tape is ejected. It must be pressed.

SUMMARY OF THE INVENTION The present invention has been made to improve the above-mentioned conventional problems. The main object of the present invention is to enable the motor of the loading apparatus to be driven by contact of the tip when the cassette tape is pushed in to load the cassette tape. The simpler structure is intended to contribute to productivity and cost reduction.

A characteristic means for this is a loading actuating member having a main frame with a side support, a power transmission extension on a suspension positioned inside the side support of the main body frame, and reciprocating the loading actuating member before and after. A reduction gear set including a connecting gear, a loading mechanism comprising a driving motor, a driven lever pinched above the side support of the main frame, and a rotation of the driven lever, By a rear end of the driven lever which is attached to an entrance / exit mechanism formed of a hook member consisting of a hook member and a support piece connected to the front end of the driven lever and the driven lever and the side support part of the main body frame. One micro switch to drive one motor, allowing cassette tape to be inserted immediately The loading motor is to be driven.

Hereinafter, a detailed configuration and its operation will be described according to the accompanying drawings.

As shown in Fig. 1 to Fig. 1, the configuration of the present invention is largely divided into a loading mechanism 1 for seating in a play position when the cassette tape is fully inserted, and an entry mechanism 2 for drawing or ejecting the cassette tape inwards. Can be.

First, the loading mechanism 1 includes a loading operation member 12, a rotation member 13, an elevating member 14, and a connecting tooth 33. In this case, the main frame 11 has a side support. Since not only has 11a but also has bottom 11b, various components can be installed and fixed.

In addition, the loading operation member 12 is located just inside the side support portion 11a, which has respective lifting grooves in the front and rear portions thereof, and in the middle of the suspension, the elongated hole 12c is formed while being bent horizontally. It has a piece 12d.

Then, the upper projection pin 33a of the connecting tooth 33 is fitted into this long hole 12c, and the connecting tooth 33 is rotated by the reduction gear set 32 driven by the motor 31. .

Meanwhile, the entry / exit mechanism 2 includes a hook member 21, a driven lever 22, and a driving lever 23, and the hook member 21 has a rotating member having the horizontal portion 21a. (13) is inserted into the sliding incision groove (13c) for hooks and movable in the forward and rearward direction, and extends forward from the horizontal portion (21a), and the hook 21b having a locking jaw below, and the horizontal portion It has a support piece 21c extending downward from 21a.

The driven lever 22 contracts the hinge point 22 in the shaft at a portion extending from the side support portion 11a, and the tip end 22b forms a sliding hole 22c to protrude 21d of the hook member 21. ), And the rear end 22d is operable to operate the micro switch 5 fixed to the side support part 11a, and the driving lever condensed with the hinge point 22 described above. 23, the extension protrusion 23a can rotate and pull the driven lever 22, and the projection 12e of the loading operation member 12 can be interlocked with the recess 23b on the opposite side.

In addition, a micro switch 5 is attached to the side support part 11a so that it can be turned on by the rear end 22d of the driven lever 22 described above.

The following describes the operating state of the present invention configured as described above.

First, as shown in the operating state for loading, as shown in Figure 3 and 4 when the cassette tape (T) is pushed into the deck, the end surface of the cassette tape (T) is the supporting piece (21c) of the hook member 21 ), And at the same time, the hook 21b of the hook member 21 is caught by the inner circumferential portion of the reel r of the cassette tape T. In this state, the hook member 21 is further applied. Since is slightly reversed, the driven lever 22 is rotated a little.

As shown in FIG. 3, when the driven lever 22 is slightly rotated, the rear end 22d turns on the micro switch 5, so that the motor 31 is driven.

When the motor 31 is driven, the connecting gear 33 rotates through the plurality of reduction gear sets 32, and when the connecting gear 33 rotates, the protruding pin 33a on the upper surface of the loading operation member 12 Since the loading operation member 12 is moved in the advancing direction (rightward direction in the drawing) because it is fitted in the extension piece 12d of the long hole 12c, the rotating member 13 and the elevating member 14 As shown in FIG. 5, the cassette tape T is loaded.

Advancing of the loading actuating member 12 is stopped when the omission 33c of the connecting gear 33 is located on the deceleration tooth set 32, which is the point at which the advancement of the loading actuating member 12 is completed. do.

When the cassette tape is pushed into the deck, the present invention as described in detail above does not use a separate sensor or a separate device to induce the operation of the loading mechanism (1), but for the extraction of the cassette tape. Since the micro switch 5 is turned on by the driven lever 22 of the already configured entry / exit mechanism 2, the structure is simple and the production cost is low.
