Title:
FLOPPY DISK RECORDING AND REPRODUCING DEVICE
Document Type and Number:
Japanese Patent JPS592269
Kind Code:
A
Abstract:
PURPOSE:To prevent the injury on the recording surface of a floppy disk, by inhibiting the loading of the 2nd floppy disk cassette even though said floppy disk is loaded mistakenly, even the loading is possible for the 1st floppy disk, by providing a hook pin of a shutter open/close mechanism. CONSTITUTION:The 2nd cassette 41 loaded into a cassette holder 1 is guided A by a guide part 2. That is, a hook pin 13 is not put into a cut 46A but hits a shutter 47 since a hook part 49 of the shutter 47 is set at the right of a hook part 39 of the 1st cassette 31. When the cassette 41 pushed in further, the shutter 47 does not shift to the left and kept closed B although an arm 11 and an action lever 21 are turned like in the case of the cassette 31. Under such conditions, the lever 21 is not turned up to the position where a cassette loading mechanism is actuated by an action bar 24 as shown in D. Therefore the cassette 41 is not loaded to a single-face device.
