When the engine is then started, the decompression cam 16 is rotated in interlocking with the rotation of the decompression arm 18 to resolve the decompressed state. At that time, the rotating range of the decompression arm 18 is regulated by stoppers 14d, 14e integrally formed with a gear 14.

Title: Automatic accompaniment device
Inventor: SATO ATSUSHI
IPC: G10H1/38
Filed: 1996-12-13
Abstract: PROBLEM TO BE SOLVED: To perform automatic accompaniment without causing jumping in a consecutive accompaniment sound. SOLUTION: Twelve sound pitches of each semitone from C to B are made to correspond to numerical values of 0 to 11 respectively. If a code 'F' is inputted to a route at the last time and a code 'G' is inputted to a route at this time, R=7 is obtained by means of a processing of E1, and D=7-5=2 (difference value) by means of a processing of E2. Since the absolute value of D does not exceed '6', the shift processing becomes NO at step E3 and the processing is performed at step E5 for becoming S=5+2=7 (shift value). Although a sign of D and S is the same, |D| does not exceed '3' and |S| does not exceed '9' either, therefore, the processing becomes NO at step E6 and goes to step E8.  Further, |S| does not exceed '12', the processing at E9 is not performed, therefore, a shift value becomes '7' in this case, and the code of accompaniment pattern data is shifted to the positive direction by 7 semitone in the root sound C.
