Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a magnetic recording medium, that is, a hop-up device for diskettes, cassette tapes, and the like.

[Purpose of the invention] Various hop-up devices have been proposed up to now, but the purpose of the present invention is to provide a hop-up device that has a simple structure and is suitable for reducing the thickness of built-in devices. It is.

[Structure of the idea]

The present invention has been made to achieve the above object, and includes a U-shaped hop-up slider equipped with a protrusion for receiving a diskette on a shaft that rotates in conjunction with a hop-up lever, and a U-shaped hop-up slider is slidably attached to the shaft.
A stopper with a stepped portion on the rear surface is fixed to the shaft between the front and rear arms of the hop-up slider, a hop-up coil spring is attached to the shaft between the front arm of the hop-up slider and the stopper, and is always pressed in the direction of the shaft, and when inserting the diskette, the front end engages with the rear surface of the stopper, and then when the shaft rotates, the front end engages with the step, and when the diskette rotates, when the shaft rotates, the front end engages with the step. A latch spring is provided that allows the front end to come off the step.

〔Example〕

An embodiment in which the present invention is applied to diskette discharge will be described below with reference to the drawings.

FIG. 1 is a perspective view of the embodiment, and numeral 1 indicates a door lever that also serves as a hop-up lever. The door opening mechanism has been omitted as it is not relevant to the main project.

Reference numeral 2 denotes a shaft that rotates in conjunction with the door lever 1, and a U-shaped hop-up slider (hereinafter simply referred to as the slider) 3 made of a metal plate is slidably attached to the shaft, and a shaft is mounted on the rear surface between the front and rear arms 3a and 3b. A stopper 4 provided with a stepped portion 4a is fixed.

5 is a hop-up coil spring mounted on the shaft 2 between the front arm 3a and the stopper 4;
Reference numeral 6 denotes an L-shaped latch plate spring fixed to the rear arm 3b, the tip of which engages with the rear surface of the stopper 4, and the side surface of the spring 6 attached so as to always press in the direction of the shaft 2.

Note that 3c is the slider 3 that receives the desk D.
The protruding piece 7 provided at is a hop-up guide.

Next, its usage and operation will be explained with reference to the operation explanatory diagram illustrated in FIG.

Figure 2a shows the movement of the hop-up device, and b
The figure is a front view showing the movement of the lever 1.

Figure A in FIG. 2 shows an initial state in which the lever 1 is set horizontally, the door (not shown) is opened, and the diskette D is not yet inserted.

When the diskette D is inserted from the insertion opening (not shown) in this state, its rear edge first hits the protrusion 3c of the slider 3, and when it is further inserted against the repulsive force of the coil spring 5, the latch leaf spring is released together with the slider 3. 6 moves rearward, and the tip moves rearward from the rear end of the stopper 4. At the same time, the latch leaf spring 6, which had been in pressure contact with the side surface of the stopper, comes off the side surface of the stopper and engages with the rear surface of the stopper as shown in Fig. 3 is locked by a stopper 4 and a coil spring 5.

Next, when the lever 1 is rotated 90 degrees clockwise as shown in Figure B to close the door, the shaft 2 is rotated and the front end of the latch leaf spring 6 is moved to the step 4a as shown in Figure A.
engage with.

Next, when the lever 1 is rotated to the open state in order to take out the diskette b, the protrusion 4b formed at the rear of the stopper due to the step 4a pushes the latch plate spring 6 sideways, and the step 4a Remove the front end of the latch leaf spring 6 that was engaged with the latch leaf spring 6.

Therefore, the diskette D is ejected from the insertion opening via the slider 3 due to the repulsive force of the coil spring 5. Figure D shows the state immediately before the lever is opened, and Figure E shows the state when the hop-up operation of the slider 3 is completed.

[Effect of idea]

Conventional hop-up devices use a lever or the like as a release mechanism, which requires space and is not suitable for thin devices, but the present invention has a stopper 4 with a stepped portion 4a and a protrusion 4b at the rear. Since the latch leaf spring 6 is removed by rotating it,
It can be made thin and is suitable as a hop-up device for thin devices.

According to this mechanism, if a micro switch is mounted on the slider 3 and is operated by the movement of the latch plate spring 6, it is possible to detect the completion of setting the diskette D. This makes it possible to use space more effectively than installing a micro switch.
