Abstract

PURPOSE:To prevent the sticked state because of the contact of heads at both sides even in the head loading state, when no disc is loaded to a floppy disc device. CONSTITUTION:The floppy disc device has heads 4 and 6 at both sides of a disc 8, and the head 4 is interlocked with a head arm 5 and a paddle 3 and moved up and down. A head stick preventing plate 9 is slidable left and right, and in loading the disc 8, the head stick preventing plate 9 is slid right, and the head 4 descends. When the disc 8 is not loaded, since the head stick preventing plate 9 is placed under the paddle 3, the head 4 does not descend. Thus, even if the head loading state takes place when no disc is loaded, there is a gap between both heads, allowing to avoid the sticking due to contact.

Side with conventional double-sided type 70 nobby disc device】@
To the head arm with the head attached? One of the methods for moving to the unloaded position and unheaded loaded position is as follows. That is, the paddle was moved to 10 in conjunction with a lever mechanism for manually opening/closing a door or manually moving a floppy disk clamp mechanism, and this paddle moved the head arm from top to bottom. A spring force is always applied to the head arm, which causes the head arm to constantly move to the V (head load position). When the paddle is raised, the head arm resists the spring force and reaches the unhead load position. When lowered, the head load position was reached by spring force.In such a floppy disk device, when a floppy disk is not inserted into the device, 1. Close the door or turn the lever to move the head arm to the head load position. When the head on side 111!l comes into contact with the head on side 0, they become stuck.After that, as soon as the door is opened or the lever is turned to move the head arm to the unhead load position, This has the disadvantage that excessive force is applied to both throats, damaging the head.

An object of the present invention is to provide a mechanism that prevents the head on side 0 and the head on side l from coming into contact with each other and becoming attracted even if the head is loaded when no floppy disk is inserted into the device. 1. [Embodiment of the Invention] An embodiment of the present invention will be described in detail below with reference to FIGS. 1 to 3. (]) A lever installed near the floppy disk insertion slot of the 11th floppy disk 11.
The lever (2) attached next to this lever (1) rotates at the same time. A clamping mechanism for clamping all spindles of the floppy disk is linked to the rotation of the shaft (2), but is not directly related to the present invention and is therefore not shown.

The operation when the floppy disk (8) is inserted into the device will be explained with reference to FIG. 1 [7]. When the floppy disk (8) is inserted, the head adsorption prevention plate (9) is pushed by the floppy disk (8) and moves to a predetermined position and remains stationary. When the lever (1) is rotated to clamp the floppy disk (8) on a spindle that is not shown in the figure by 1 degree, the shaft (2) rotates and the paddle (3) is lowered. When the handle (3) is lowered, the head arm (5) is loaded onto the head adsorption prevention plate.
