摘要： PURPOSE:To scan a head in parallel with high accuracy without the need for special adjustment, by providing a buffer cylinder between the head and an auxiliary shaft and absorbing an error of fitting between a head main shaft and the auxiliary shaft by means of the piston movement of the buffer cylinder. CONSTITUTION:The main shaft 13 and the auxiliary shaft 14 are fixed to bases 11, 12 with screws and the error buffer cylinder 20 absorbing mounting error between the shafts 13 and 14 and a slide bush 24 are provided between the head 15 and the auxiliary axis 14. The buffer cylinder 20 is accommodated in a hole 23 so as to be in piston movement toward the arrow (a). Through this constitution, the horizontal mounting error of the auxiliary shaft toward the arrow (b), i.e., a distance change between the shafts 13 and 14 is absorbed with the piston movement of the buffer cylinder 20. Thus, the head 15 is scanned in parallel with high accuracy without the need for special adjustment of the mounting of the shafts.

摘要： PURPOSE:To improve the positioning accuracy of a magnetic head by providing a means to adjust a fitting angle of a stepping motor in the straight line movement direction, and eliminating a clearance between a pulley and a steel belt at the time of assembling. CONSTITUTION:An adjusting screw 12 to correct a clearance between a pulley 2 and a steel belt 3 of a stepping motor 1 by pushing the stepping motor 1 from a chassis 11 is installed. When the stepping motor 1 is fitted to the chassis 11, the falling of the motor 1 occurs due to the gap of the tightening force of the screw for fitting, the variance, etc., of a processing accuracy of respective parts, and the pulley 2 and the steel belt 3 are not right-angled, and the clearance will occur. The falling of the stepping motor 1 is corrected by tightening the adjusting screw 12, and adjusted so that the clearance between the pulley 2 and the steel belt 3 can be eliminated. Thus, the positioning accuracy of the head can be improved.

摘要： PURPOSE:To simplify the structure, and to reduce the cost and to increase the accuracy of positioning at the time of head driving by providing a groove on a part of magnetic head carriage, giving elasticity to its edge and using it as tension application part. CONSTITUTION:A groove 1'c is made on a carriage 1' which mounts the magnetic head not shown in the figure, and when a steel belt 3a-3c (transmission means) are attached to carriage 1' and a pulley 2, the edge part 1'd (tension application part) of the carriage 1' moves slightly in the arrow C direction, and it pulls the steel belt 3b through the steel belts 3a, 3c and the pulley 2. Therefore, the belt 3a-3c is stretched straightly without sag. Since there is no necessity to attach other materials such as plate spring to the carriage, it is possible to obtain accurate positioning when the head drives.
摘要翻译：目的：为了简化结构，降低成本，并通过在磁头托架的一部分设置凹槽来提高头部驱动时的定位精度，使其边缘具有弹性并将其用作张力应用部件。构成：在安装图中未示出的磁头的滑架1'上形成有槽1'c，当钢带3a-3c（传动装置）安装在滑架1'和滑轮2上时，边缘滑架1'的第1部分（张力施加部）沿箭头C方向稍微移动，并且通过钢带3a，3c和滑轮2拉动钢带3b。因此，带3a-3c被拉伸没有下垂。由于不需要将诸如板簧的其他材料附接到滑架上，所以当磁头驱动时可以获得准确的定位。
