摘要： PROBLEM TO BE SOLVED: To provide a highly reliable and compact mechanism having a small driving load applied during loading by preventing damage caused by unexpected interference generated during loading between a guide post mounted on a tape guide post transferring means and a rotary head cylinder regarding a mechanism used for a magnetic recording/ reproducing device. SOLUTION: The tip part of an inclined post 46 is provided with a tapered shape 46a in a direction where a diameter is reduced from the lower side of the upper end of a magnetic tape to the upper side of the upper end of the same. Thus, unexpected damage is prevented from being given to a rotary head drum or a head during loading without enlarging a mechanism or increasing a load during loading.

摘要： PROBLEM TO BE SOLVED: To solve a problem that a space occupied by a tensile spring over the entire operation becomes very large because the rotational range of a pinch arm is large and the tensile spring is stretched and contracted and moved left/right accompanying this movement over a wide range, thereby hindering the device from miniaturizing. SOLUTION: Even when a return spring 96 is extended accompanying the rotation of a pinch roller arm 90, actually, a winding angle on a pressure spring 100 is only increased, and a space occupied by the return spring 96 is very small. Thus, effects contributing to the miniaturization of the device are obtained. Additionally, since the outer periphery of the spring is generally smooth, and the outer periphery of the return spring 96 is always in contact with the crimping spring 100, sound generated during the sudden elongation/contraction of the spring is suppressed, and moving sound is quiet.

摘要： PROBLEM TO BE SOLVED: To provide a reel base which winds up a magnetic tape with uniform torque precisely in a magnetic tape recording and reproducing device, which allows precision tiny torque to be transferred, and which is strong to external force such as lateral pressure and is also inexpensive.
SOLUTION: A first rotary body and a second rotary body are made to contact through a friction member, and a force is applied to between a sliding section of a fixed cap bottom and the first rotary body by an elastic holding member. By making the second rotary body 2 and a fixed cap 5 screw together so as to adjust the spacing of the first rotary body and the fixed cap bottom and by rotating the fixed cap 5, the length of a wire spring 4 varied without going through steps, adjusts a transferred torque. This ensures the transmission of precision tiny torque.

摘要： PROBLEM TO BE SOLVED: To provide a magnetic recording/reproducing device wherein a structure is simple and the occurrence of tape damage is hardly caused. SOLUTION: Since a V groove 71 is formed to engage a T3 post arm 58 with the housing 72 of a capstan, no change occurs in a relative relation with a T post 60 even when the inclination of a capstan shaft 56 is adjusted, and tape damage is difficult to occur. Since the rotational center of the inclination adjustment is set near the height of the T3 post arm 58, the effect of preventing the generation of unnecessary force caused by the adjustment is obtained. Thus, a problem is solved, that when large tension is generated on a magnetic tape 12, the large force of an arrow direction F is generated in the T3 post, the T3 post arm is deformed, the position of the T3 post is shifted to become the situation of easily generating tape damage.

摘要： PROBLEM TO BE SOLVED: To obviate the infallibility of the exact detection of the beginning end and terminal end of a magnetic tape by the reflected light at an under-the- tape flange unless a prism is disposed with the conventional device which detects the beginning end and terminal ends of the magnetic tape of a DV mini-cassette by a difference in the transmittance of light, such as IR light. SOLUTION: The height of a light emitting source 2 is positioned upper by 1.5 mm from a standard center 7 of the DV mini-cassette and the height of a light receiving element 3 is positioned lower by 1.0 mm than the standard center 7 of the DV mini-cassette, by which the incidence of the reflected light at the under-the-tape flange 1 on the light receiving element 3 is averted and the beginning end and terminal end of the magnetic tape are exactly detected. As a result, the malfunction by the reflected light is eliminated.

摘要： PURPOSE:To release quickly the interruption of the brake lever after starting the DC motor and to brake instantaneously the reel stand by communicating the action of the thrust direction of the warm gear through a selecting lever and a kicking lever to a subrod. CONSTITUTION:When a DC motor 25 is rotated, rotation is transferred through a motor pulley 26 and a belt 27 to a worm gear 30 and the worm gear 30 is shifted in the A direction. A selecting lever 33 is guided to a shaft 35, shifted in the A direction, simultaneously, engaged to a slot 33a of a selecting lever 33, a shaft 38 caulked at a kicking lever 37 is shifted in the A direction and the kicking lever 37 is also shifted. As this result, the interruption of a subrod 42, in which the shifting in the B direction is interrupted, is released, the subrod is guided to a shaft 40 by the energizing force of a subrod spring 41, and shifted in the B direction until it contacts with a fixing stopper 52. The interruption of a main brake lever 43 is released, the main brake lever 43 is pulled to a brake spring 44 and a reel stand 45 is braked.
