This turntable design has a direct drive system instead of belt drive (two types). If this unit has been in storage for some time, it has most likely been at hot or cold tempuratures - not good for any electronic/mechanical system. 
My guess is that the direct drive motor needs to be rebuilt - internal friction is probably keeping it from operating at proper speed. Best to consult with a repair shop that can handle direct drive turntables - several on the internet, if you cannot find one locally.

BTW: You can find a manual for this at :

Belt fell off

There are two main types of phonograph turntable drives still being manufactured today, the belt-drive and direct-drive systems; the names are based upon the type of motor system found in each.
In a belt drive turntable the motor is located under and to the side of the platter and is connected to the platter by an elastomeric belt.
The design of the belt drive turntable allows the use of a less expensive motor than the direct-drive turntable. Also, the elastomeric belt absorbs motor vibrations which would otherwise be picked up by the stylus.

Running VERY slowly

The thing to do is to check the belt first, then look at things like is there a build up of grease dirt anywhere. Clean up the platter make certain no grease or dirt is the works causing it to slow down.
See also that the motor that drives the belt can turn freely and very easy by hand.

My drive belt came off i do not know how to put it back on please help! I have a Denon - Fully Automatic Turntable System - DP-29F It doesn't give me much help in the instructions on how to put it back on.

1. Remove the rubber disc from the metal platter.
2. Remove the metal platter by pulling straight up.
3. Ignore the player for the moment; focus on the platter.
4. On the underside of the platter is a circle about 2 inches smaller than the platter; stretch the belt around that inner circle. Make sure it is not twisted.
5. Put the platter back on the player. Rotate the platter so that one of the rectangular holes reveals the drive wheel.
6. Stretch the belt so that it goes around the drive wheel (I used a pencil but tweezers would likely work well).
7. Replace the rubber disc.

I just bought a used DP26F and see that under the platter the belt goes around only a spinning thing (sorry) near the front, but nothing else. Something must be connected to whatever it is that spins the...

This picture is from the manual for a DP-29F, a similar belt-drive turntable:


The view is through the rectangular hole in the platter you see with the turntable mat removed. This picture is from the setup section for a new turntable, so the ribbon tape won't be on your belt. But it shows how the belt should go around the drive roller (it's the shaft of the drive motor underneath). Other than the routing of the belt over the roller, there's nothing else to connect. If the belt is working correctly (hasn't stretched so it's too loose), the roller drives the belt which in turn spins the platter. If your turntable isn't turning, either the belt is too loose to transmit the motion, the drive motor isn't spinning, or something is binding and preventing the platter from turning.

Platter won't turn

Souds like the belt has snapped or slipped off. Lift the platter off the table. On the inside of the platter you will notice a second ring, or rim. the belt should be put on the outside of the second rim while the platter is still in your hands. Next, slide back the platter and look for the spindle running the platter through one of the big holes in the platter. Slip the belt onto the spindle and turn with your hand to make sure it runs freely. Hope this helpsmicmor100.jpg

Denon DP-29F belt is loose

please not this is when first set up but may help

The drive belt is fitted under the platter. When assembling the
player, please handle the drive belt with care.
• Remove all packing materials attached to the tone arm, except
that on the stylus, and then open the dust cover and assemble.
Remove the stylus cover after assembling.
Hold the platter by the holes at its outer surface, and
then carefully lower the platter so that the center
spindle enters the center hole.
Rotate the platter until one of its outer openings is
aligned with the driving roller. (Refer to illustration.)
Gently grasp and pull at the ribbon tape of the drive
belt that is would under the turntable, and then
extend the belt around the driving roller. (After
attaching, remove the ribbon tape.)
In order to make sure that the drive belt has been
correctly fitted, slowly rotate the platter 3 or 4 turns.
Place the rubber mat on the platter.
IMPORTANT! Please Check.
Check that the drive belt and ribbon tape have been attached
under the platter. Grasp the ribbon tape as shown in the
illustration to the left, and extend it onto the driving roller.

Help~~ the belt fall off

Most turntables have the belt wrapped around the bottom of the turntable platter, and then around the motor. You'll have to remove the rubber mat, to expose some holes on the platter, where you can squeeze your fingers in to pinch/wrap the belt around the motor shaft - generally on the lower left side. You can't miss it. Also, for future reference, here is the operating manual for your unit, and it has instructions on replacement the belt - it is on page 6:
