摘要： PROBLEM TO BE SOLVED: To provide a lens barrel capable of achieving highly precise position detection.
SOLUTION: The zoom lens barrel 1 includes: a cylindrical main body frame 18; a cam frame 15 where a first cam groove 45 and a groove for a sensor 56 are formed; a first cam pin 42; a second lens group 21 which can not be turned with respect to the first cam pin 42; a pin for a sensor 55; and a sensor 54 for detecting the displacement amount of the pin for the sensor 55. The first cam pin 42 and the pin for the sensor 55 are engaged with the first cam groove 45 and the groove for the sensor 56 respectively in a freely slidable manner. By relatively turning the cam frame 15 to the main body frame 18, the pin for the sensor 55 is interlocked with the first cam pin 42 and the second lens group 21 and displaced in an optical axis direction A with respect to the cam frame 15.

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： PURPOSE:To reduce the size and thickness of the rotary head drum device without impairing the out of roundness of a stationary drum by providing a tape guide part with an inclined lead for guiding the bottom end of a tape. CONSTITUTION:An inclined level difference is constituted by providing a relief part 23 having the diameter D3 nearly equal to the diameter D1 of the tape guide part 19 of the stationary drum 20 and forming the outer peripheral part 21 of diameter D2 larger than D1, D3 to a band shape, by which the bottom end face of the magnetic tape 16 is regulated. As a result, the thickness on the outer periphery of the stationary drum is uniformalized and the out of roundness of the tape guide part is assured. In addition, the formation of the thinner stationary drum is possible.

摘要： PURPOSE:To realize a thin motor part with less parts by providing a spacer means between a magnetic flux concentration means and a magnet supporting means, constituting the outer periphery of a preload means as a guide and abutting the edge surface part of the spacer means on the magnet supporting means so as to obtain a prescribed clearance. CONSTITUTION:Ball bearings 14 for supporting a shaft 12, fixed transformers 18 for transmitting a signal from a magnetic head 16, a stator 20 for rotating a motor are fixed to a lower drum 10 for guiding a magnetic tape. The winding wire of the transformers 18 is relayed to a flexible substrate 24 and is connected to the rotation part of a mainbody. On the other hand, a rotary drum 30 where the magnetic head 16 is provided for the disk 26 fixed to the shaft 12 is fixed to a rotation-side, and a preload is given to the shaft 12 by a preload boss 32 and a vis 32. The sub-rotor 54 of a magnetic material plate and a ring resin spacer 50 are provided at the outer-side of the boss 32. Thus, the edge surface part 58 of the spacer 50 is abutted on a magnet 52 and the clearance between a rotor magnet 56 and the sub-rotor 54 is maintained constant.

摘要： PURPOSE:To independently and compactly adjust the relative height of a head chip by providing a thin wall part whose thickness is thinned so as to be orthogonal to the projecting direction of a holding piece, on a root part of the holding piece. CONSTITUTION:In a body part of a head chip holding member 9, a groove 10 is provided on a root part of two holding pieces 9A, 9B projected so as to be adjacent to each other, so that both end parts of the body part of the head chip holding member 9 are installed to a rotary cylinder 6. By installing the body part of the head chip holding member 9 to the rotary cylinder 6, and pressing the points of length of about 1/2 of projected length of two holding pieces, respectively, with an adjusting screw 7 provided on its rotary cylinder 6, the relative height of a head chip 2 provided on the holding pieces 9A, 9B can be adjusted independently. In such a way, a magnetic head device which can adjust easily height of the head chip can be realized by a compact shape.
