This paper deals with the basic experimental results on the mechanical signal generator, which is applicable as the signal source in the push-button telephone set or the end apparatus of data transmission.　As the signal source of the equipment shown in this paper, the tuning forks are used, and the reed vibrators can be also used.　The largest problem in the equipment using the mechanical vibrator is the rise and fall time of signal. The equipment described here has the quick rise time by giving an initial displacement to the mechanical vibrator.　When the signal generator is set into operation, the magnetic binding force to the vibrator disappears and then the vibrator begins to vibrate in the free damped vibration. The signal generated with the free damped vibration is picked up piezo-electrically or magnetically.　Two kinds of the construction of the signal generator are described in this paper, one is the electromagnetic drive and piezo-electric pick up type, and the other is the electromagnetic drive and electromagnetic pich up one.　This equipment has wide application and will be used widely.
