Goodday to all, 
How to convert audio cassette to cd. I know there is a tutorial available on net. Sorry guys, I find my connection going wrong. Here’s rough sketch of device (back view).

thanx in adv.
on your pc,there is one microphone,one line out and one line in jack! Connect the line out from your recorder to the line in on your comp and use softwares that all recording through line-in!
P.S: I guess one of the microphone jacks (that you have marked as red on PC) is actually a line-in
On your audio cassette deck there should be Audio Out / Line out port. give its o/p 2 PC line In.
If you give speaker o/p to Pc your sound card will burn!
do you have a stereo to RCA cable ?

that should be used to connect the recording output to the line in ( blue ) connector
Thanks a lot all there. I will try these solution & let u know
and remember to select aux or line in as your recording input
