An object of the invention is to provide a control device for an internal combustion engine that regularly and forcefully removes deposit that is accumulated in cylinders and restrains consecutive occurrences of pre-ignition beforehand. The internal combustion engine has a low-speed pre-ignition region in which a possibility of occurrence of pre-ignition increases, in a low-rotation and high-load region. Ignition means (16) for igniting an air-fuel mixture taken into the cylinders is included. When an operation region is in a region other than the low-speed pre-ignition region and in a forceful knock enabling region with a load equivalent to or higher than a lower limit load at which knocking can be forcefully generated by advance of ignition timing, the ignition timing by the ignition means is forcefully advanced at a predetermined control interval, and a maximum in-cylinder pressure that is higher than at a time of ordinary combustion in the operation region and is lower than at a time of occurrence of pre-ignition is generated. The control interval is made longer as a load of the operation region is higher, and the control interval is made shorter as the load of the operation region is lower.

The invention relates to an orbital transferring mechanism for conveying a card reader holder. The orbital transferring mechanism comprises two conveying bands that are arranged along the same height and extended horizontally. The conveying bands are used for conveying the card reader holder along the same movement direction. Fixed baffle plates are arranged at two sides of the upper part of the conveying bands. The orbital transferring mechanism is characterized in that the rear end of one conveying band is overlapped with the head of the other conveying band along the movement direction. Movable baffle plates are arranged at the two sides of the upper part of only one conveying band. The baffle plate is capable of horizontally moving along the direction vertical to the movement direction of the conveying band. The orbital transferring mechanism disclosed by the invention is capable of transferring orbit of the card holders on the conveying bands that moves at a relatively high speed to convey the card holder to the other conveying band that moves at a relatively low speed, so that the card holder movement at variable speed is realized without influencing the running of the relatively high speed conveying band. Therefore, the moving speed of the card holder is relatively low when the card holder is conveyed to an operator and the operator is easy to keep pace with the operation.
