Abstract

PURPOSE: To reduce the time loss due to the erroneous insertion of the medium by detecting the erroneous insertion when the medium is set in the floppy disk device member in the stage of insertion.
CONSTITUTION: This device is constructed by a door at a medium inserting port in the front of the device, a control circuit 7 receiving a signal from a detector 5 provided to the device, a display lamp 9 and a buzzer 10 for informing of the erroneous insertion by the signal from the control circuit 7. In the case when a jacket 2 is inserted under the condition as shown in the figure, the detector 5 senses a reflecting tape 3' on a surface of the jacket and feeds an erroneous insertion detecting signal to a control circuit 7. The control circuit 7 receives this signal to light the display lamp 9 and ring the alarm buzzer 10 and inform it to the operator. Accordingly, the erroneous insertion of the floppy desk medium can be instantaneously informed to the operator and the time loss is limited to the minimum.
