JPS5812156A - Lock releasing mechanism for quick forward and rewind of auto-reverse cassette car stereo reproducer - Google Patents

Abstract

PURPOSE:To release lock only with no change of a program although a program switch is pushed, by pushing the program switch to actuates plunger and then actuating a lock lever to release the lock. CONSTITUTION:A quick forward lever or a rewind lever is pushed up to make the hook part of a lock lever 13 separate from the pawl of a ratchet 1. Thus a current flows to an energizing coil 12 of a plunger 8 to suck the plunger 8, and the ratchet 1 is kept at rest. A pinch roller 26 or 27 have an alternate contact with a forward rotary shaft 24 or a rewind rotary shaft 25 by pushing the quick forward lever or the rewind lever. Thus a cassette tape is quickly forwarded or rewound to switch the program and to lead out the head of the tape. The power supply current is supplied to the coil 12 by means of a program switch 9 after switching the desired program. Thus the plunger 8 is sucked to reset the quick forward lever or the rewind lever.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an auto reverse Φ cassette car stereo 0J.
At the II raw value position, if you press the program switch while the tape is in fast-forward mode, the Goo/Tsum will not change, and the fast-forward 9 machine 111 mode will release the 1IjlR mechanism O lock. Regarding the mechanism that causes

The plunger lever works, moves the switching cam, switches the pinch roller, and sends the cassette tape in the opposite direction, which changes the position of the cassette tape.For this reason, if you do not press the Pgram switch again, the force will remain the same. It was not possible to adjust the tape by simply pressing the 1vA7'W rubber switch. Before I could stop the cassette tape, I had to press the fast forward switch or the rewind switch.

Tei Ji @'s objective, auto reverse cassette car stereo OJI! On the recording device, tape O fast forward or *
There is a reproducing device 1m in which, even if the program switch is pressed during the operation of ST, the program does not change and the same program can be reproduced by unlocking only the fast forward or rewind mechanism.

Another object of the present invention is that when the second or reverse side of a cassette tape is being played, if it is necessary to play Oth track after that or 0IIlli1 after some number of tracks, the fast forward lever or @jIL lever can be pressed. Operate, fast forward the cassette tape, and rewind it nine times.

The break in the bell sound of the cassette tape is detected by a detection mechanism such as a contact ball or contact piece, and the detected signal is used to operate the plunger lever by passing an electric current through the plunger coil to activate the fast forward P lever or reverse return lever OEI. Remove the ivy.

There is K, which makes it possible to carry out the necessary cocoon selection and regeneration and provides a nine-density extraction mechanism.

The present invention uses a fast-forwarding spooler and a rewind lever.

Program a plunger lever that engages with or separates from the pawl of the mold wheel to rotate the mold wheel and stop the cassette wheel, which has a cam that switches between the pinch 4 roller for forward feeding of the cassette tape and the pinch low 2 t for reverse feed 9. The electric S is operated by the excitation coil of the plunger, which is opened and closed by a switch, and the fast-forward lever is locked by pressing the rewind lever and locked by the lock lever. 111 from the model car's claw by the plunger lever engaged with the claw of
1 Remove the tape, stop it at the original position without rotating the model wheel, perform the switching operation of the binterotsu, perform fast forwarding or rewinding of the cassette tape O, and then remove the cassette tape O.
By pressing the program switch during the operation of *St, the excitation coil of the Shipzunger is excited to operate the Granger, and at the same time, the four levers are operated and the fast-forward p lever is activated. This auto-reverse cassette car stereo playback device has a fast forward/rewind oa mixer mechanism to unlock and play the original program.

Other objects, configurations, functions, and effects will be explained with reference to the drawings of the embodiments.

98 claws 2 are formed on the front side by dividing them at equal angles,
The four long aSSs on the back 11 and the shank part 6 on the fourth side are connected to the claw 2.
Similarly, cams 7 are formed which are divided at equal angles and arranged alternately in correspondence with the respective claws 2. 8 is set by program switch 9 to p car battery 10km.
A granger 13 is connected to the granger 8 by a bottle 14, and has a hook portion at the tip that engages and separates from the claw 2 of the mold wheel l. 15 with 9 levers, 16
is pivoted to the machine frame 3 through a bin 17, the tip of which is connected to the plunger 8, which engages with the ninth bin 111, and the other end of which is connected to the rapid-forwarding siller 1.

3 about the bottle 14 in the counterclockwise direction, the hook 15 is removed from the pawl 3 of the mold wheel 2, and the mold wheel 2t7 is rotated. Reference numeral 23 indicates a plunger lever 13 and a return spring 1M of the plunger 13 stretched over the machine frame 3, which is a cassette tape feed lever.

Nine plunger levers 13, 1-shaped part 2! ! is pushed counterclockwise in FIG. 2, centering on the bottle 14, against the tension of the spring n, thereby separating the hook portion 15 from the pawl 2 of the mold wheel l. Therefore, even if a current flows through the excitation coil 12 of the plunger 8 and attracts the plunger 8, and the plunger 8 is moved to the left in FIG. Car l remains stationary. The front of the fast forward p lever 19 is the rewind reno (-20), as in the conventional way, the pinch roller gst9 is rotated to switch to fast forward or rewind. A cassette tape (not shown) is alternately contacted with the rotating shaft 25.
t-Fast-forward like nine is IIjI, change the program and cue it, then switch the desired program and place it at the end of the tape (according to the nine idiomatic fragments) to the t-playback head. Detecting this, the program switch 9 connects the power supply at to the P excitation coil 12 and pulls the plunger 8. Therefore, the tip of the lock lever 16 is pulled by the pin 18 of the plunger 8 and rotates counterclockwise in FIG. 113.

When the lock lever 16 is locked to the bottle 21 at the base of the lever 16, the fast forward lever 19 and the lever 19 and 20 are rolled up and the engaging part 19at or 20& of the lever 20 separates from the bottle 21, causing premature death (due to a spring (not shown) Return lever 19 or return lever 20 to its original position.
jl.

As described above, the present invention is advantageous in that when switching the program of a cassette tape, when the fast-forward lever or the rewind lever is pushed up, the fast-forward P lever or the rewind lever is engaged with the hook of the plunger lever and the pawl of the mold wheel. You can release the cassette tape to fast-forward the cassette tape and perform the first rewind operation, and even if you press the program switch and operate the plunger after pressing the program switch, the hook of the plunger lever will not work. Since it does not engage the pawl of the mold wheel and only performs air feed p, the program does not change and the rapid feed p lever or Ijl
There are effects such as being able to rotate the lever.
