Abstract
When an electronic card is inserted into the device, a first reject plate is pressed to elongate first and second coil springs to anchor the card. When no writing or reading ROM and RAM of the card, electric current instantaneously flows through a solenoid to cause a stopper stopping a second reject plate to rotate through a slight angle so as to disengage the stopper from a front end of the second reject plate. As a result, the second reject plate is depressed by the second coil spring. At the same time, a reject arm provided on the second reject plate moves a reject oblique surface of a card latch to move the card latch through a slight angle to lower a card guide, so that the card is pushed by the first coil spring out of the device. In this manner, the card is not pushed out during writing or reading and hence contents of the card are not damaged. A solenoid requires only a force for moving the stopper through a small distance. The small solenoid and a little power are sufficient to operate the device. As the card is pushed out by the first coil a sufficient pushing device is obtained, so that the device can be used for many years without fatigue of the device.
