Abstract

PURPOSE:To assure the operation of a disk cartridge loading device with no contact nor collision between a cartridge and a magnetic head, by permitting the ejection of the cartridge only when the cartridge is detached from the magnetic head in an ejection scan mode of the cartridge. CONSTITUTION:When an ejection operation button 18 is pushed, a holder 12 is set at the 3rd position higher than the initial 1st position and a cartridge 17 is separated completely from a magnetic head 1a. In this case, an arm 14 is also set at the 3rd position turned counterclockwise more than the 1st position. An extended part of 14b of the arm 14 holds up an end part 21b of a cartridge hook member attached to the holder 12, and a cartridge hook member 21 is rocked counterclockwise with a slot 12b of the holder 12 used as a fulcrum. Thus the hook is released between a positioning hole 17b of the cartridge and a projection 21a of the member 21. Then the left-right shift limitation of the cartridge is released and a support member 13 is energized left by a support member spring 15. Thus a bent part 13b of the member 13 moves to the left while ejecting the cartridge 17 to the left side and is reset back to the 1st position where the part 13b can hold a holder pin 12a.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a diskcar I-Ridge station name device that can be used in a floppy disk drive 6 using a diskcar I-Ridge.

-3- Problems with the conventional configuration and B In recent years, floppy disk drives have been used in many ways as information recording means. There are floppy disk devices on the market that use cartridges (hereinafter referred to as blade-1 to cartridge) as recording media. It is necessary to ensure that the cartridge is installed without colliding with the recording/reproducing magnetic head in the device, and that the magnetic head finally comes into contact with the magnetic disk in the cartridge through the head window installed in the cartridge. For this reason, generally, the cartridge is once fed into a predetermined position in the device in one direction, and then
By moving the cartridge from that position substantially perpendicular to the direction of insertion of the cartridges, the above requirement is achieved. When the cartridge is ejected from the device, the opposite operation is performed. Such an operation is a one-touch operation ('lni'), such as simply pressing one operation button provided on the device.

Hereinafter, with reference to the drawings, an example of a conventional cartridge loading device will be described. 1+ 1 figure is C(

The hole 7C is a head window that is opened for contact with the magnetic head 1a and other magnetic disks in the cartridge 7, and 8 is an ejection operation button fixed to the front end of the sliding plate 4 in the cartridge insertion direction. . In addition, head positioning v! Since A structure 1f is not directly related to the present invention, its explanation will be omitted below.

Although the chassis 1 is not shown in FIG. 2, the sliding plate 4 slides on the upper surface of the chassis, and the support member 3 slides on the upper surface of the sliding plate 4. In addition, the four holder bins 28 attached to the side of the holder 2 are attached to the side of the holder 2.
R) Hi 101n Y Me(,, rl, When the car 1 of the holder 2 is regulated in the insertion direction of the ridge, the sliding plate 4 that can move in the car 1 to the ridge insertion direction
The holder 2 is fitted into the inclined notch /'la to restrict the downward direction of the holder 2.

The operation of (J configuration (\reI, - force - tridge station name) J3 in the f position is explained below in 1. The state before the ridge is installed is shown in Figure 2. According to △, 1. The holder pin 2a is fitted into the inclined notch 4a of the plate 4, which is a circle Φ) which is biased by the sliding plate biasing spring 6 in the direction Ij opposite to the insertion direction of the slide plate.

7- When the cartridge is turned, the tip of the cartridge comes into contact with the bent portion 3b of the support member 3, and the support member 3 moves in the car 1-ridge insertion direction. Therefore, the support part 3a supporting the holder pin 2a
escapes from the holder pin 2a, and the holder pin 2a moves toward the inclined plate biasing spring 6 in the opposite direction to the cartridge insertion direction.
It moves downward along the inclined notch 4a of the sliding plate 4, which is biased by , and along the curve iff 1 e of the chassis 1.

FIG. 2B shows the state when the car 1 is attached to the heli- zage, and the holder 2 is attached to the magnetic head 1a from the first position.
It moves vertically in the direction of and reaches the second position. In this second position, as shown in FIG. 3B, the cartridge 7 is moved in the height direction and in the vertical direction in FIG. ) and in the front-back direction (left-right direction in FIG. 3), the disk in the cartridge 7 and the magnetic head 1a come into contact through the head window 7G of the cartridge 7, and information in the disk is read and written. . During the ejecting operation, press the ejector f1 button 8, and as shown in Fig. 2C, the sliding plate 4 moves the holder bin 2a to the holder bin 2a by the slope of the inclined notch 4. From position 2 to the first (to the hair device): Insert the hair from position 1 to the ridge, facing right in Figure 2 C)
Slide to. Roughly speaking, 1) By pushing in the 1-out operation bokun 8, the holder 2 is moved up to the 10th neck via the porgoo pin 2a, and the cartridge 7 escapes from the cartridge support pin 1h and moves forward and backward (see Fig. 2). The restriction in the horizontal direction) is released, and the support member 3 is pulled back by the support member spring 5, causing the ridge 7 to extend to the car 1 at its bent portion 31), -], and at the same time, the boulder pin 2a is supported by the support part 3a and returned to the initial first position.

However, in the IF configuration as shown in L, there are many sliding parts, so K also lacks the flexibility of the jJ11 output operation, and the operating force for the ejection button 8 is large. 1+=, J shown in FIG. , due to an external force that pulls out the cartridge 7, such as gravity when the disk device is installed in a forward-down position, the cartridge 7 moves to the support member before it completely ascends to the first position. There is a possibility that the cartridge 7 is ejected in a state where the holder pin 3 does not support the holder pin 2a. In this state, since the holder 2 is located closer to the magnetic head 1a than the first position of the cartridge mounting surface, there is a possibility that the cartridge 7 will come into contact with or collide with the magnetic head 1a as shown in FIG. Even if the holder bin 2a is ejected without colliding with the magnetic head 1a, the holder 2 moves to the second position again because the supporting member 3 does not support the holder bin 2a, and when the cartridge 7 is reinserted, the holder bin 2a is ejected. The problem was that the cartridge 7 collided with the air head 1a, making it impossible to mount it.

OBJECTS OF THE INVENTION An object of the present invention is to have a simple structure, and to enable the cartridge to be ejected only when the cartridge is separated from the magnetic head during cartridge ejection scanning, so that the cartridge and the magnetic head come into contact or collide.

It is limited to the configuration of car 1-.
In the process of the t7171 ejecting operation of the cartridge 11, if the cartridge 1-ridge 17 has not sufficiently escaped from the magnetic head 11a, the locking member provided on the holder 12 locks the cartridge. Anything is good as long as it has the ability to do this.For example, by using a 1/1 bullet such as A11 as the locking member and making contact with the car 1~ridge, the gap between the elastic body and the cartridge is 4. It is possible to use a structure in which the car 1 to the ridge are locked by frictional force.

From the effect of the invention)-It is obvious that J: '), the wooden structure is simpler than the previous example, and the structure of the car 1~ritsuji and the center hub. Pressure is applied, and a cartridge locking/disengaging mechanism is attached to the holder that holds Car 1 to Car 1. When the cartridge is ejected, the cartridge can be moved up to 1 m without the possibility of contacting or colliding with the magnetic head. At this point, the cartridge locking/unlocking mechanism releases the cartridge.

The cartridge is configured to be able to eject the cartridge 111, and when there is a possibility that the cartridge and the magnetic head come into contact with each other during the ejection operation, ejection of the cartridge is prevented and the cart 20 is - An excellent effect can be obtained in that the ridge is prevented from damaging the magnetic head and causing damage to the magnetic head.
