Abstract: PROBLEM TO BE SOLVED: To perform a high-speed operation without damaging a tape-shaped recording medium. SOLUTION: A tape drive unit 1 in which a tape-shaped recording medium 102 is pulled out from the inside of the case body 101 of a tape cassette 100 and run by using a loading mechanism, is provided with a drum 17 around which the tape-shaped recording medium pulled out from the case inside of the body is wound and slide-contacted, and a tension detection mechanism which gives constant tension to the tape-shaped recording medium in the state where the tape-shaped recording medium is pulled out and a tape path is formed. The setting of the high-speed operation mode during non-winding for performing the high-speed operation is enabled while the tension detection mechanism gives the constant tension to the tape-shaped recording medium in the state where the tape-shaped recording medium is not wound around the drum.

Abstract: PROBLEM TO BE SOLVED: To enhance durability by preventing deformation of a connector in moving the connector into a position to be in contact with contact terminals when an end part on the side of the contact terminals of an auxiliary storage device of a tape cartridge is lowered to a loading completion position. SOLUTION: In the video tape recorder 60 concerned, a movable connector holder 72 for movably supporting the connector 71 is driven by a connector holder driving mechanism 73. The tape cartridge 1 mounted with the auxiliary storage device 50 to be connected with the contact terminals 53 is loaded into this recorder 60. At this time, the connector 71 is moved to escape into a position not in contact with the cartridge 1 by the mechanism 73 until the end part on the side of the terminals 53 is lowered to the loading completion position. Then, after the end part of the terminals 53 is lowered, a spring terminal 101 of the connector 71 is moved into a position to be in contact with the terminals 53 by the mechanism 73, so as to read out storage information of the device 50. Consequently, the connector is prevented from flawing, and the durability is enhanced.

Abstract: PURPOSE: To ensure insertion of a tape cassette by using a space in the height direction of a top cover and giving an erroneous insertion preventive function to a tape cassette push-out mechanism. CONSTITUTION: A tape cassette push-out mechanism 20 engages a cassette holder lock arm 2 with an abutting piece 6A of a slide drive plate 6b at the time of ejecting operation, and maintains an ejection state of a cassette holder 1. When the tape cassette 3 is inserted erroneously, a recessed part of a slide lock groove 22a of a push lever 22 is engaged with a slide pin 21B of a left X lever 21, and a lock state is maintained, and loading operation is prohibited. Further, when the tape cassette 3 is inserted normally, the holder 1 presses the lever 21 uniformly, and the pin 21B slides on the recessed part, and the loading operation is performed without engaging. Thus, even in a cassette compartment of e.g. 3.5 inch standard height, the insertion of the tape cassette is ensured.

Abstract: PURPOSE: To detect tension in plural modes by arranging a freely rotatable guide roller in slidable contact with a tape as a tension arm on one end side and regulating a space with a rotary shaft. CONSTITUTION: An output voltage from a Hall element 15 for tension is so small as about 0.65(V) in a range of tension of 11-20(g). At the time of calculating tension as a load on the tape by using this output voltage curve, a tension amt. can accurately be detected by utilizing a linearlike tendency of this curve. A linear output voltage characteristic is shown enough even in a region of low tension of 6-8. Consequently, accurate tension can thus be detected in a tension detecting rage of 7-20(g).

Abstract: PURPOSE:To perform the locking of a cassette holder by a work part by providing the work part on a transmission wheel arranged in the driving mechanism for moving a cassette holder and pressing the cassette holder by the work part with the transmission wheel being rotated when moved to a cassette holder loading position. CONSTITUTION:When a cassette holder is moved to its descent position, the work part 57 of a worm gear 35 presses an arm 56 to be pressed provided on a segment gear 39 and the rotation of a pressing gear is checked. The cassette holder is thus locked by a work part 57 via the pressing gear the need for an exclusive locking mechanism is eliminated, the number of parts is reduced and the mechanism can be simplified as well.

Abstract: PURPOSE:To check the movement of a cassette holder to its loading position by providing a locking means so as to check the movement of the cassette holder and effecting locking motion with the locking means being engaged with the cassette holder in two stages. CONSTITUTION:The pins 17, 18 formed on both side plates of a cassette holder 16 are made to fit to these guide grooves 13, 15 and the front loading of a tape cassette is thus enabled. A lock lever 20 is fitted to the right side frame 11 and made to engage with the part to be locked of the cassette holder 16. Two step parts 21, 22 are formed on the right side side-late of the cassette holder 16, forming the part to be locked. The lock lever 20 is made to engage with the step parts 21, 22 of the cassette holder 16 and the cassette holder 16 being moved to loading position in the state of holding no tape cassette 60 is thus prevented.
