Description

The present invention relates to a receiver mechanism of, for example, a 3.5-inch floppy disk drive.

(Prior Art) Conventionally, for example, a floppy disk drive of 3.5 inches or the like uses a recording medium housed in a hard case, and when this recording medium is inserted into the apparatus main body, it is chucked by a spindle mechanism. You. In this case, as shown in FIG. 4, the recording medium is held by the receiver 10 provided in the apparatus main body, and is chucked by the spindle mechanism by the downward movement of the receiver 10. By operating the eject button 11, the receiver 10 moves upward in conjunction with the eject mechanism to detach the recording medium from the spindle mechanism. The detached recording medium is ejected from inside the apparatus main body by being pushed out of the receiver 10 by the ejection mechanism.

The receiver 10 is a frame having a flat portion corresponding to the upper surface of the hard case storing the recording medium and side portions for supporting both sides of the hard case. Conventionally, the size of the receiver 10 in the width direction is larger than the width of the hard case, and is formed so that the hard case can be easily put in and out. That is, when the hard case is held by the receiver 10, a slight gap is formed between the side surface of the receiver 10 and the side surface of the hard case. For this reason, the hard case is easily ejected from the receiver 10 at the time of ejection, but the hard case may be ejected too much at the time of ejection due to manufacturing variations of the ejection mechanism.

(Problems to be Solved by the Invention) Conventionally, in a floppy disk device having a receiver 10, a recording medium (stored in a hard case) held by the receiver 10 may be ejected from the receiver 10 too much when ejected. Things can happen. For this reason, there is a problem that the recording medium jumps out of the apparatus main body at the time of the ejection and falls down to the floor, for example, and the recording medium is damaged.

SUMMARY OF THE INVENTION An object of the present invention is to provide a receiver mechanism of a floppy disk drive capable of stably ejecting a recording medium by limiting the amount of ejection of the recording medium from the receiver at the time of ejection.

[Structure of the Invention] (Means and Action for Solving the Problems) The present invention utilizes a frictional force with a side portion of a receiver when a recording medium held by the receiver is ejected in a floppy disk drive. Thus, the receiver mechanism is configured to limit the amount of ejection of the recording medium. As a specific means, there is provided a spring mechanism which is attached to the side surface of the receiver and contacts the side surface of the recording medium and presses the recording medium against one of the side surfaces of the receiver at least at the time of ejection.

Further, a member is provided which is attached to the side surface of the receiver and which generates a predetermined contact frictional force on each side surface of the recording medium and the receiver at least at the time of ejection by contacting the side surface of the recording medium.

With such a mechanism, it is possible to limit the amount of ejection of the recording medium at the time of ejection by using the frictional force between the receiver and the recording medium, and realize an appropriate ejection operation.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. First
FIG. 2 is a plan view showing the configuration of the first embodiment of the present invention, and FIG. 2 is a side view. As shown in FIG. 1, an ejector 13, a receiver 14, a carriage 15, a stepping motor 16 for driving the carriage 15 and a shutter opener mechanism 17 are provided on a frame 12 in the floppy disk device main body. The ejector 13 is a member constituting an ejection mechanism, and has a mechanism for moving the receiver 14 up and down. The receiver 14 is formed of a frame that holds a recording medium (stored in a hard case) inserted into the apparatus main body in the direction of arrow A, and moves downward to move the recording medium to a spindle mechanism (not shown). Is a member for chucking. A carp-shaped spring member 18 is attached to the upper surface of the receiver 14 of the embodiment. As shown in FIG. 2, the spring member 18 comes into contact with the recording medium 21 held by the receiver 14 through a notch 19 formed in the side surface of the receiver 14, (In the direction of arrow B in FIG. 1).

The carriage 15 is moved in the radial direction of the recording medium by the driving force of the stepping motor 16, and positions each magnetic head (each of the magnetic heads S0 and S1 (not shown)) on a predetermined track. Further, the shutter opener mechanism 17 opens a shutter provided in the hard case, and brings the recording medium 21 held by the receiver 14 into contact with each magnetic head held by the carriage 15. Also, a shutter opener mechanism
17 rotates in the direction of arrow C in FIG. 1 upon ejection,
A push pin 22 for pushing the recording medium held by the receiver 14 is provided.

Next, the operation and effect of the first embodiment will be described. First, when the recording medium 21 accommodated in the hard case is inserted from the direction of arrow A in FIG. 1, the recording medium 21 is held by the receiver 14. That is, as shown in FIG. 2, the recording medium 21 is held by the receiver 14. At this time, the recording medium 21 is inserted in the depth direction of the receiver 14 while the side surface of the recording medium 21 is in contact with the distal end portion 20 of the spring member 18. When the insertion of the recording medium 21 is completed, the receiver 14 moves downward and chucks the recording medium 21 by the spindle mechanism. As a result, the recording medium 21 is driven to rotate by the spindle mechanism and comes into contact with each magnetic head mounted on the carriage 15.

Next, when the eject button 11 is operated, the ejector 13 moves in the depth direction of the apparatus main body, and moves the receiver 14 upward. That is, the receiver 14 is lifted to the eject position. When the receiver 14 rises to a predetermined position, the push-out pin 22 of the shutter opener 17 rotates in the direction of arrow C, and the recording medium 21 held by the receiver 14
It works to push out. At this time, the recording medium 21 held by the receiver 14 is in contact with the distal end portion 20 of the spring member 18 and is pressed toward the opposite side surface of the receiver 14. Therefore, the recording medium 21 is pushed out from the receiver 14 while being pressed against the side surface of the receiver 14. As a result, the amount of protrusion of the recording medium 21 when the recording medium 21 is pushed out of the receiver 14 is relatively limited due to the frictional force with the side surface of the receiver 14.

In this way, the recording medium is
When the recording medium is extruded from, the recording medium is constantly pressed against the side surface of the receiver by the spring member.
Therefore, a relatively large frictional force acts between the recording medium and the receiver 14, and the amount of the recording medium ejected from the receiver 14 is restricted. As a result, the ejection amount of the recording medium during ejection increases,
For example, it is possible to prevent a situation such that the recording medium is damaged by dropping to the floor.

FIG. 3 is a plan view according to a second embodiment of the present invention. In the second embodiment, the side surface of the receiver 14 is cut out.
19 is provided with an elastic member 23 made of, for example, a rubber material. The elastic member 23 comes into contact with the side surface of the recording medium held by the receiver 14, and generates a frictional force with the recording medium at the time of ejection. Therefore, when the recording medium is ejected from the receiver 14 at the time of ejection, the amount of the recording medium ejected from the receiver 14 is limited by the frictional force with the elastic member 23. As a result, similarly to the first embodiment, it is possible to prevent the recording medium from jumping out at the time of ejecting and to prevent the recording medium from falling to the floor and being damaged.

The other configuration and operation and effect are the same as those of the first embodiment, and the description is omitted.

[Effects of the Invention] As described above in detail, according to the present invention, in a floppy disk device having a receiver, when the recording medium is pushed out of the receiver at the time of ejection, the amount of ejection of the recording medium is relatively limited, and As a result, it is possible to prevent the situation from jumping out too much. Therefore, a stable ejection operation can always be realized, and for example, it is possible to reliably prevent a situation where the ejected recording medium jumps out of the apparatus main body, falls to the floor, and is damaged. .
