ABSTRACT:
A tape loading device for a recording and/or reproducing apparatus, comprises a loading mechanism for drawing out a tape from a tape cassette which has supply and take-up reels, and for loading the tape unto a predetermined tape path, brakes for respectively braking reel discs which rotate the reels, tension controllers for respectively controlling tensions in the tape which is drawn out from the reels, a detector for detecting an arrival of the loading mechanism to an intermediate position, and a control circuit. The control circuit makes one brake operative and the other brake inoperative during a first half of an operation stage in which the tape is drawn around the periphery of a guide drum, and makes both brakes inoperative and both tension controllers operative during a latter half of the operation stage. The first half of the operation stage continues until the detector detects the arrival of the loading mechanism to the intermediate position, and the latter half of the operation stage continues until the tape loading operation is completed. The one brake brakes one reel disc which rotates one reel from which a certain tape path extends, which certain tape path increases its length as the tape loading operation progresses and is one of a pair of tape paths which are formed as the tape is drawn out from each of the reels.
