Noob, Cassette player ejecting blank tape.

[AutoLuxLexES]

Hello all,

I am working on an audio project with my cassette player from my factory automotive radio. I have been doing a lot of research on cassette players in general, but am still searching. What I do know is that there are many different ways that a cassette player will eject tapes. In my situation, I am wanting to know more information on how a cassette player ejects a blank tape?

Thanks
Charley

In my experience there is a mechanical tensioner sensor on the tape drive. When the transport senses End Of Tape (EOT), the tape tension increases on the drive reel and the capstan releases and the tape ejects. You might be able to wire in a manual eject if the sensor is electrical. If it is mechanical, and trips the eject linkage, you may have to live with it.

Pray tell, which model are we talking about? Pictures would help. Why do you want to learn about tape ejection? There are others here on this site with far more knowledge of tape transport mechanisms than I.

Are you trying to say that you put the tape in and it doesn't play and then ejects? If that is the problem then a belt is probably bad and needs to be replaced, or something else is broken.

If you mean that tape comes out of the cassette and gets around the parts and is mangled then you have to clean the tape path and likely demagnetize it as well. If you don't know what that needs to be done, ask a repairman or friend that knows how to do this. Car stereos need care just like home decks yet are routinely run without any for a long time...with proper care a car stereo can last the life of your car, unless you want to put a better one, with more or different features in perhaps. You have to care for them and fix them though.

Hello all,

This is a Pioneer deck with tape,cd, AM, and FM. From the research I've found, the tape player is model CX-529.

A little background about my project. Roughly 2 months ago, I successfully installed an Aux jack into the tape players output signals so that I can listen to my music from Iphone( important since I drive M-F 150+ miles a day for school). when testing to see if everything works, I used a gutted tape, but the player recognized it being empty and spit it out. So then I tried a blank tape, and BAM, it worked fine. But after 2 months, the aux cable(from Aux port to phone) is failing and starting to get annoying. I've seen my cousin use a similar Belkin(Quality) cable, and it still went bad through time. Not to mention the hassle with a cord laying around your car.
So About 1 week ago, I realized that I can install a bluetooth receiver for semi cheap. The plan is to remove as much mechanical parts, and use the structure of the tape player to setup my circuit for the bluetooth and extra USB for other gadgets. So here is a diagram of my circuit(ignore red circle)

So with just about everything ready for install, I am held up on how to trick the cassette player into thinking a tape is in there, when there really isn't any tape at all. I've already gutted a majority of what I think can safely be removed( and will post a pic up tomorrow).


As for the ejecting, it is not doing any of the issues described. Actually my tape player works perfectly fine, but what I am wanting to know is how does the tape player know when the cassette's internals have been removed? because blank tapes will play, but something in the player can sense when the tape has been gutted. the real estate of the tape player is prime in setting up my bluetooth receiver and an extra USB for phone charging.

Thanks
Charley

Is there anything in the gutted shell? Can you put a blank tape in and it works? It may sense there is no tape so it kicks it out. Just like if the tape breaks. That is the only thing I can think of.

Do you expect the cassette deck to still function correctly after your modification?

Pretty cool.

Or just adapt a cassette adapter.

Or just get an fm transmitter with a 1/8inch headphone jack, plug it into your phone and tune your radio to the appropriate fm frequency. The transmitters let you use a wide variety of fm frequencies and they retail for about $10 or so. I just bought a few last weekend at a closeout electronics store for $2.95 each. They run off of two AAA batteries and have a range of 3 to 10 meters.

Or you can get one at Amazon for $1.64 plus $2.98 shipping. It even comes with a remote.

The reason the gutted cassete fails is if you took the tape out the hubs in the deck no longer turn, and if you took the tape out and left the hubs in the cassette tape then one of the decks spindles turns way too fast and the other doesn't turn at all signalling to the deck that the tape has reached the end.
