摘要： PROBLEM TO BE SOLVED: To solve problems of a conventional art, in which charge voltage charged in a capacitor 1 is applied to a primary coil 3a until the next ignition operation and the primary coil 3a cannot be connected with a secondary coil 3b so that the number of connection terminals of an ignition coil 3 becomes large to increase a cost, and in which the charge voltage of the capacitor 1 is charged to the connection terminals of the primary coil 3a and a plate for indicating 'handle with care' is required to increase the cost.
SOLUTION: Since a switch means 4 for driving the ignition coil is disposed between the capacitor 1 and a primary high pressure side connection terminal 11, the charge voltage charged in the capacitor 1 is not applied to the primary high pressure side connection terminal 11 until the next ignition operation. Therefore, a low pressure side of the primary coil 3a can be connected with a low pressure side of the secondary coil 3b, and the number of the connection terminals of the ignition coil 3 is reduced to be two. The charge voltage is not applied to the primary high pressure side connection terminal 11 until the next ignition operation, the plate for indicating 'handle with care' can be eliminated.

摘要翻译：要解决的问题：为了解决现有技术中的问题，其中将充电在电容器1中的充电电压施加到初级线圈3a直到下一次点火操作并且初级线圈3a不能与次级线圈3b连接，点火线圈3的连接端子数量变大，成本增加，并且电容器1的充电电压被充电到初级线圈3a的连接端子，并且需要小心地指示“手柄”的板增加成本。解决方案：由于用于驱动点火线圈的开关装置4设置在电容器1和主高压侧连接端子11之间，所以将电容器1中充电的充电电压不施加到初级高压侧连接端子11直到下一个点火操作。因此，初级线圈3a的低压侧能够与次级线圈3b的低压侧连接，点火线圈3的连接端子的数量减少为2。直到下一个点火操作，充电电压不施加到主高压侧连接端子11，可以消除用于指示“小心处理”的板。
