Abstract: PURPOSE: To accurately position tape guides always at the time of completion of loading by constituting so that protruding parts for contact are brought into contact with a chassis at the different protruding part respectively at the time during the loading operation and at the time of completion of the loading operation. CONSTITUTION: A guide base 10 and a guide roller 14 are positioned in such a manner that the protruding parts 28, 28 for contact of the front side formed at the rear surface of a guide base 10 are slid in contact with the chassis 30 by a slide member 8 of the loading mechanism at the time of loading and unloading operations, and the protruding parts 29, 29 for contact of the back side formed at the rear surface of the guide base 10 are brought into contact with the chassis 30 in the state the loading is completed. Consequently, the protruding parts 29, 29 for contact are not worn even the running operation of the slide member 8 is repeated, then the guide roller is always accurately positioned at the time of completion of loading.

Abstract: PURPOSE:To prevent a tape from flawing even when the tape is given excessive tape tension when a tape drawing guide is guided by a can means by providing a stopper mechanism on the inner side of the guide. CONSTITUTION:A lock mechanism is released, so that a guide supporting part suppressing member 11 is rotated in the direction of S. According to the rotation of the member 11, a gear 11b is also rotated to drive a gear 14a of a mode slider 14, so that the slider 14 is moved in the direction of an arrow U. By this movement, a cam groove 14b provided in the slider 14 is also moved to the right, and when a cam pin 12b of a stopper 12 reaches an area having a broad width of the can groove 14b, the stopper 12 is rotated around its rotary axis 12a in the direction of an arrow V. In the drawing and loading state, even when a tape drawing guide supporting body 1 is drawn to the inner side by working tape tension on its tape drawing guide 1a, the body 1 is positioned by the stopper 12, and is not brought further to the inner side.

Abstract: PURPOSE:To obtain a cassette loading device for a recording/reproducing device capable of eliminating incompatibility in design and use of a cassette insertion window part and its limit and eliminating a limit in terms of designing. CONSTITUTION:Difference level parts 4c and 4c for guiding the insertion of a small cassette 27 on a cassette component door 4, a part of the cassette component door 4 is to be of a dividing system and large cassette detection doors 13a and 13b for detecting a large cassette are provided. Then, by door stoppers 20 and 21 linked with the large cassette detection doors 13a and 13b, the rotational limit angle of the cassette component door 4 is changed in accordance with the size of the cassette.

Abstract: PURPOSE:To reduce the size, weight and cost of the device by enabling indirect driving to rotate reel bases with existing motors, such as capstan motors, without using the motors to be exclusively used for the reel bases. CONSTITUTION:This recording and reproducing device is mountable with two tape cassettes of different sizes respectively varying in the spacings between two tape reels fixed respectively separately with both ends of magnetic tape and wound with these tapes and is constituted to move the two reel bases respectively separately engaging with the two tape reels described above in two positions. These reel bases 16, 16' are so constituted that the reel bases are turnable around fulcra 16a, 16'a supported on a mechanical chassis 17 so as to make the reel bases movable respectively to the two positions. A driving gear 39 which is supported on an oscillating arm 38 and is driven by the capstan motor 29 is meshed with one of the driven gears 19, 19' disposed on the two reel bases described above. The reel bases are rotated by this driving gear.

Abstract: PURPOSE:To eliminate complicated operation and to release the lock with a simple mechanism by providing a lock lever freely turnably locking one reel base and a pulley releasing the lock of the lock lever. CONSTITUTION:When the disabled ejection is detected by a sensor, a capstan motor not used for the loading is driven and a pulley 11 is driven clockwise via a gear and a timing belt 13. A projection 12 is driven clockwise by the drive of the pulley 11 to push the turning piece 22 of the lock lever 20 in the direction of arrow (e) thereby driving the lock lever 20 in the direction of arrow (e) and releasing the lock of the lock lever 20. When the lock of the lock lever is released, the reel base 2 is driven and the tape required for the loading is drawn from the reel loaded to the reel base 2.

Abstract: PURPOSE:To take up easily and securely a tape in any case by driving momentarily a rotating drum to rotate in the take-up direction when the part of a tape at the take-up side is peeled off from the outer circumferential surface of the rotating drum after the take-up operation starts. CONSTITUTION:Upper and lower loading rings 67 and 68 are rotated clockwise and counterclockwise to start taking up the tape. As the take-up operation advances, the majority of the take-up side separates from the outer circumferential surface of the drum although the other side is wound around the outer circumferential surface of the head drum 57. When the take-up operation further advances to some extent, the upper drum 63 of the drum 57 is rotated in the take-up direction only momentarily. This rotation is performed preferably when the majority of the take-up side of the tape 12 separates from the drum 57 as shown by a two alternate long and short dashes line. When the upper drum 63 is rotated in the tape take-up direction, the other side of the tape 12 other than the take-up side is peeled off from the outer circumferential surface of the head drum 57 by momentary tension caused by the rotation of the upper drum 63 and is taken up around a tape reel 14 as it is.
