PURPOSE:To improve efficiency, workability and reliability by semiautomatically measuring and inspecting physical characteristics of the head of VTR at a time. CONSTITUTION:Sample 1 in sample supply carrier 12 is carried to a measurement position under microscope 10 by mechanism part 8 and the track width of sample 1 is expanded and projected upon monitor TV3, which generates electron line 3a on the screen on TV control part 4 movably, through microscope 10 and TV camera 9. When line 3a is positioned at the track width position, control part 4 converts the interval of line 3a into the distance of the image of microspcope 10, which is displayed on panel 5. Inductance, insulating resistance and conduction resistance are measured by measuring instrument 6 with measurement part 13 brought into contact with terminals 1d and 1e of sample 1 and then displayed on panel 5. Microcomputer 14 in box 11 makes a decision between acceptance and rejection as a result of the inspection; and a rejected sample is carried out by mechanism part 8 and accepted one is stored in carrier 15.
