Akai GX-747 ... One of the most remembered and sought-after reel-to-reel recorder although, arguably, not the "best" - we could name the Technics RS-1500U series ...

First take out the battery. Then start unscrewing the outside panels to take it apart. Basically any screw you find, take off. The easiest way not to loose them is by sticking them into the side of a box. After you get the camera panels off, you should be able to carefully get inside and dislodge anything that may be in the way. Once you are able to dislodge the cord or whatever is causing this problem. Try inserting the battery and ejecting the tape. Let me know if you are having any trouble with this or have any other questions and I would be glad to help.

Good luck

sir,
If any of your electronics system not using for long period, remember this things( detach the battery or power source , take out cassette or memory card, if the unit use in built chargeable battery, charge it occasionally.
just connect to the power, you don"t power on your camera, the charging light will flicker then push the eject button, remember do not on the power of your cam, hop that this will solve your problem.

How to unlock your RR/L322 with dead battery

http://www.rangerovers.net/forum/6-range-rover-mark-iii-l322/38786-how-unlock-your-rr-l322-dead-battery.html

I found this on the range rover site.... hopefuly this helps with your model. You just have to pop one of the lights off to get to the postive wire then strips some of the wire and use a battery pack to send enough power to open the doors.
Hopefuly that helps

Tape is jummed inside,don't force to opened take to the repair shop

Follow this procedure to troubleshoot if the cassette compartment will not open or the tape is stuck and will not eject.
IMPORTANT: If your camcorder model has a RESET button, first try pressing this button. If there is no RESET button, or pressing the button does not resolve the issue, continue with the troubleshooting steps below.

1. Turn off the camcorder.
2. Remove the battery from the camera.
3. Remove the AC power supply from the camera.
4. Slide the power switch on the camera to the VTR , VCR or CAMERA mode for 15 seconds.
5. Slide the power switch back to the OFF position.
6. Connect the AC power supply to the camera.
7. Attempt to open the cassette compartment.

NOTE: If the issue is still unresolved after completing all of the troubleshooting steps, service may be required .

I had the same problem. I hope you have a battery charger. The many older batteries I have needed charging, but they wouldn't hold a charge when I tried to charge them with the battery charger. My batteries were the kind that had a memory, and I guess that the battery memories are dead. So, I saw that I had a double ended power cord that came with my camera. I took the battery out of the camera and saw a power-in hole. I just tried connecting the double ended power cord to the camera and to a power hole I found on the battery charger. It worked and gave power to the camera. It did not explode. I could not find a manual on any of the many websites. I think that the camera I bought (Panasonic Palmcorder IQ PV-IQ403) doesn't exist in the available manuals. Maybe you can find a double ended power cord and a battery charger on line or in a store.

The following information might be useful to others. The camera cassette door will not open without having the power on to the camera. The camera connects to a TV with RCA cords.

My camera power switch has 2 settings. Use the camera setting to use the camera to record and see what you are recording displayed on the TV. You must change the power switch to the VCR setting in order to play back the recording and see it on the TV. Change the switch back again to use the camera. (You can also see the playback through the viewfinder.)

My camera has a remote control which is stored in a slot. I found that the battery is in a tiny sliding door. I had to use a screwdriver to gently dislodge it from the case, my fingernail was not strong enough. The movable tab had to be pushed inward to release the catch. The coin battery was not corroded.

In order to play a VHS-C tape, you must have a VHS PlayPak. The cassette door will not open unless you have a battery loaded into the cassette. When the door opens, you can insert the VHS-C tape into the opening. The VHS PlayPak holder is the same size as a regular VHS tape. It can be found on-line.

look for a tiny pinhole and insert a pin while powered up to reset the device

The most frequent cause of this type situation is not having a power source attached, or a depleted battery pack. Once the power source is available, some models require manually unlatching and opening the cassette compartment cover. When the cover is fully open, the videocassette will eject automatically. Please try the following procedures. 1. Attach the power source to the camcorder correctly or use a fully-charged battery pack. 2. Fully-open the cassette compartment cover until it stops while sliding and holding the OPEN/EJECT switch. The videocassette will eject automatically after a few seconds. If the videocassette still will not eject, seek assistance from a Canon Service Facility.
