Abstract
PURPOSE: To detect and watch the damages of a typeprinting hammer, inferiority in the operational period of the typeprinting hammer or the like, by directly detecting the operation of the typeprinting hammer with a detector which detects impacts by the operation of the typeprinting hammer.
CONSTITUTION: When a typeprinting hammer 1 is driven by a typeprinting command, the projecting side surface 13 of a hammer head comes in contact with a buffer 91 and compresses the buffer 91 against a couple of opposite electrodes 94, 95. An electric circuit shown as the dotted line C is constructed through the part of the hammer head 11, and a closed circuit including a power source 97, a lead 96, a resistor R, the individual electrode 95, the direction-Z electric circuit of an elastic member 91 (which has an electric conductivity along said direction only), the hammer 1, the elastic member 91, a common electrode 94 and the power source 97 is formed. As a result, a potential-difference voltage is generated between the two ends of the resistor R.
