PURPOSE:To make sure the lowering of the capacity of a battery and prevent false printing, etc. being accompanied by the lowering by putting a mark for confirming a waiting condition to a drive system turning during a printing cycle in a recording type electronic apparatus driven by means of the battery. CONSTITUTION:A body of revolution 10 is fixed to a shaft drawn from an output shaft of a gear group, which makes a turn during one printing cycle among the gear groups 2-6 of a printer 1, and a mark 11 is put on one section of the circumferential surface. The mark 11 is placed at the uppermost location when the body of revolution 10 turns and returns to a waiting condition, and can be confirmed with eyes from an opening section 13 of a case. When the capacity of a battery is within a proper range, the mark 11 can be observed from the opening section 13; when the capacity lowers, the mark 11 cannot be viewed because the body of revolution 10 cannot make a turn. When utilizing a drive system rotating by 1/n during the one printing cycle, n pieces of the marks may be put on a circumferential surface of the body of revolution at regular intervals. |
