AUTOMATIC KEYBOARD INSPECTION INSTRUMENT

摘要

PROBLEM TO BE SOLVED: To shorten an inspection term by inspecting plural inspection items with one inspection instrument by discriminating the propriety of whether the depressing shallowness/depth of a depressed key is settled within a set range or not and displaying the propriety discriminated result for each key on a keyboard to be inspected. SOLUTION: A resistance value measuring part 10 measures the resistance value of the contact of a switch caused by the key depressed by the key depressing means of a keyboard 30 to be inspected and discriminates whether the value is settled within a resistance value range set in advance or not. A depth measuring part 15 for key depression discriminates the propriety of whether the depressing operation stroke of the key depressed by the key depressing means is settled within the depression shallowness/depth inside the set range set in advance or not while controlling the depressing load of the key by a current solenoid load control part 18. Then, the propriety discriminated results of the resistance value measuring part 10 and the depth measuring part 15 for key depression are displayed on a display part 33 by the respective keys on the keyboard 30 to be inspected.
