摘要： PURPOSE:To improve and uniformize the image quality by adjusting an extent of projection of a magnetic head chip with a high precision without damaging or deforming an upper cylinder. CONSTITUTION:When a stepping motor 25 is rotated to move a pressing block 20, a projecting part 29 is brought into contact with a through hole 9, and a gap delta is just zero. When the pressing block 20 is moved furthermore hereafter, a head base 3 is pushed out by a contacting part 10 of a lever pin 8 in accordance with the part 29 as the fulcrum. When the gap delta is zero, a force is applied to a pressing pin 21, and a distortion detection signal exceeding a discrimination threshold is generated suddenly. Meanwhile, a television camera 27 and a image processor 32 recognize the front end position of a magnetic gead chip 2 in the initial state and input it to a microprocessor 30, and the microprocessor operates an extent of adjustment by which the magnetic head chip 2 should be moved.

摘要： PURPOSE:To position a magnetic head to a head base highly precisely and in addition, in a short time, and to stick it by the pressing force of a constant value by detecting and adjusting a target position at which the magnetic head is to be stuck, the set position of the magnetic head, and the pressing force. CONSTITUTION:At a stage that the head base 2 and magnetic heads 1, 1' are positioned and set, the target position at which the magnetic heads 1, 1' are to be stuck and the set position of the magnetic heads 1, 1' are detected, and the correction quantity of the magnetic heads 1, 1' to the target position is measured. Then, they are positioned on the basis of the correction quantity. Accordingly, the magnetic heads 1, 1' can be positioned to the head base 2 highly precisely and in a short time. Further, the pressing force is detected, and the magnetic heads 1, 1' are stuck to the head base 2 while this pressing force being held so as to be the constant value. Accordingly, the dispersion of the finished size of the magnetic head can be absorbed, and the magnetic head can be stuck under constant sticking pressure.

摘要： PURPOSE:To achieve a handy detection of poor insertion without damaging a part to be detected, by using a contact pin with a flat tip in stead of direct contact of lead of an electronic component or providing a post for preventing pressurization by the dead weight of a contact pin. CONSTITUTION:Contact pins 4a and 4b are formed at position corresponding to leads 2a and 2b of an electronic component 1 as supported with a guide 24. An electrode plate 8, a piezoelectric rubber 9 and an electrode plate 10 are set in contact with the guide 24. The electrode plates 8 and 10 employ a flexible printed circuit board forming electrodes 6 and 11 at positions corresponding to the leads while a post 7 is provided for preventing pressurization by the dead weight of the contact pin 4. When a pressing force is applied to the contact pin 4, the electrode plate 8, the piezoelectric rubber 9 and the electrode plate 10 form a conducting circuit to detect poor insertion. This enables detection of poor insertion without any damage to a part to be detected with a small and handy construction.

摘要： PURPOSE:To accurately position a magnetic head to the center of rotation of a rotary cylinder even if there is an error in machining by measuring the center position of the bearing part of the rotary cylinder and the inclination of its center axis, and adjusting the position of the magnetic head according to a calculated correcting quantity. CONSTITUTION:Two noncontact displacement gauges 22 are inserted into the bearing part of the rotary cylinder 1 from above and below and the distances between the two displacement gauges 22 and 22 and the bearing part of the rotary cylinder 1 are measured over the entire circumference. Then the inclination of the bearing part center shaft of the rotary cylinder 1 to the rotary center shaft of a rotary mounting table 9 is calculated from variation in distance above and below the bearing part of the rotary cylinder 1, and the magnetic head 2 is shifted in position by the correcting quantity corresponding to the inclination of the shaft, thereby adjusting the magnetic head 2 to an accurate position according to the bearing part of the rotary cylinder 1 even if there is error in the machining as to the bearing part and outward shape of the rotary cylinder 1.
