When the pedal solenoid automatically returns from the operating state to the non-operating state, a loud impact noise is generated when the pedal solenoid rapidly returns to the non-operating state.
There is a fulllli. Therefore, the present invention outputs aftertouch data smaller than the solenoid holding data to the solenoid drive means for a predetermined period of time from when the pedal should be in the non-operated state, thereby returning the pedal to the non-operating state. The kll prephonic interval mt-resolved which occurs when An embodiment of the present invention will be described below with reference to the drawings.
Ru. FIG. 1 is a block diagram showing a pedal solenoid drive circuit to which the method according to the present invention is applied. In this figure, when the pedal data generating circuit 1 is supplied with the pedal control signal C shown in Figure 1 (A), the wrinkles in the circuit 1 as shown in Figure 1 (B) and ■ are gradually reduced over time. Data PD[- that changes T is created and supplied to the drive signal generation circuit 2 (solenoid drive means). Incidentally, time t1 in IIJIiI3 (a) is the timing when the pedal 8 is in the operated state, and time t is the timing when the pedal is in the non-operated state. The drive signal generation circuit 2 generates a solenoid drive signal with a constant period having a pulse width T corresponding to the length of the data PD supplied from the pedal data generation circuit 1, and outputs it to the solenoid 4. As a result, the solenoid 6 is driven and the pedal 8 is brought into operation. Here, the above-mentioned pedal data generation circuit 1 will be described in further detail. First, time 1. When the pedal control signal C is supplied at 82rlJ (b), the T attack data PD is displayed. is output for a time T1. Here, attack data PD
, is the data of the Solenoid Society's plunger escaping from the static stage. Next, touch data PD! is output for a time T. This touch data FIX is data for bringing the plunger of solenoid 6 into a completely protruding state, and its value is smaller than attack data PD. Next, solenoid holding data FD, ) output ■
Ru. This solenoid holding data PDs is Q] data in order to hold the plunger of the solenoid & in its protruding state in its downward motion, and the whale is the touch data PD. It is smaller. Thereafter, this solenoid holding data PDsft is continuously output until the pedal control signal C is turned off. Then, when the pedal control signal C turns off at time t, the aftertouch data a P D4E l5l

When a solenoid drive signal having a pulse width corresponding to T is supplied to the solenoid 1, the plunger of the solenoid gradually returns from its extended state, and as a result, the pedal 8 gradually returns to its non-operated state. In addition, the above-mentioned data PD1 to PD, and time T
INT is determined by the characteristics of the solenoid number and the pitch of the pedal 8.As explained above, according to this method, the predetermined weight aftertouch data [solenoid Since the output T is output to the drive means (drive signal generation circuit 2), the pedal can be gradually returned from the operating state to the non-operating state.
