PURPOSE:To eliminate an uneven reproduction which is caused by the number of sheets stacked, by applying the push-up force in accordance with the weight of the magnetic recording medium from the lower part of the recording medium of the lowest part. CONSTITUTION:In the automatic reproduction mode, the supply mode change-over switch 121 is switched to the automatic side with the sound recording/reproducing change-over switch 15 switched to the reproduction side. Furthermore the reset button 142 is pressed to reset the count display of the counter 141, and the sound volume is controlled to a proper level via the sound volume adjuster 131. Then several sheets of magnetic cards are cut like the playing cards to change properly the order of reproduction. These magnetic cards are inserted into the card storing chamber 21 through the card insertion inlet 111 until the tip of the card hits the stopper bar 225 at the vertical part of the guide 221. In this case, the rotating angle of the supporting plate 214 varies according to the weight of the magnetic cards, and the plate 214 is energized to the upper side by the force of the spring 216. In such way, the pressure contact force between the magnetic card on the highest surface and the supplying roller 31 can always be kept contact regardless of the number of the magnetic cards. |
