Problems solved by technology

However, in this case, the clamping of the magnetic disk inside the casing becomes unstable, and when external vibration acts, the magnetic disk in the ejection completion position that should be stopped is likely to fall off.

Embodiment Construction

[0049] In the magnetic disk drive 1 according to the embodiment of the present invention, the Y1 direction is the loading direction (inner direction), the Y2 direction is the unloading direction (outer direction), the X1 direction is the left side, and the X2 direction is the right side. In addition, the Z1 direction is upward and the Z2 direction is downward.

[0050] figure 1 is a perspective view viewed from above, figure 2 with image 3 It is a plan view seen from above. Figure 4 with Figure 5 is the top view viewed from the underside, Figure 4 with Figure 5 The left and right direction (X1-X2 direction) and figure 2 as well as image 3 The left and right directions of are opposite. Figure 6 ~ Figure 8 The cross-sectional view of is shown with the Z1 direction directed upward in the figure. Image 6 The X1 direction in the middle is the right direction in the figure. Figure 7 The loading direction (Y1 direction) is the direction shown in the figure, Fig...

Abstract

The invention provides a disk device which is set to stably keep conveying completion gesture stop so as to increase the projection size of disk from insert / discharge opening. When the disk (D) discharged out from a housing stops in a discharge gesture, the rear end of the disk (D) is compressed and held in an inner side abutment portion (Ti) and an outer abutment portion (To) of a disk guide member (30) through a conveying pin roller (23). The height dimension (H2) from the upper surface of the disk guide member (30) (i.e., a support reference surface (A)) is set to be greater than the height dimension (H1) from the support reference surface (A) to the outer side abutment portion (To), and in this way, the disk (D) is corrected into the state that a projection side of the disk (D) face upward, and then the disk is difficult to fall under the action of external vibration.

Description

technical field [0001] The present invention relates to a magnetic disk device in which a magnetic disk is stably held in an ejection completion posture protruding from an insertion / ejection port during ejection of the magnetic disk. Background technique [0002] As described in Patent Document 1 and the like, in a magnetic disk device used as a vehicle, etc., a slit-shaped insertion / ejection port is formed on the front edge portion (corresponding to Japanese: ノーズ portion) of the front portion of the casing, and the magnetic disk moves along the The direction of this surface is inserted into the housing from the insertion / discharge port. In the housing, the magnetic disk is carried inward by a conveying mechanism having conveying rollers, and the center hole of the magnetic disk is clamped (corresponding to Japanese: cramp) on the turntable of the rotary drive unit. In addition, the magnetic disk is rotationally driven by the rotary drive unit, and information is read or wr...
