[Industrial applications]

 The present invention relates to an improvement of a cartridge mounting device that attaches and detaches a disc cartridge such as a mini disc cartridge and a floppy disc cartridge to a drive unit for recording / reproducing the cartridge.

[0002]

[Prior art]

 In recent years, a disc cartridge (hereinafter referred to as "cartridge") in which an information recording disc is housed in a protective cartridge case has been proposed. For example, FIG. 2 shows an example of this type of cartridge, and is a plan view of a magneto-optical recording type mini disk cartridge (hereinafter referred to as "MD"). As shown in FIG. 2, the MD includes a cartridge case 1, an information recording disk 2 housed in the case 1, a disk access hole 3 provided in the case 1, and a slide for opening and closing the access hole 3. A shutter 4 and a spindle hole 5 for rotating the disk 2 are provided. In such an MD, the shutter 4 closes the access hole 3 except when it is used, so that the disk 2 inside the case 1 is protected from the external environment and is excellent in practicality and durability.

As a device for recording / reproducing such a cartridge, a disc device that accommodates a plurality of cartridges at the same time can be considered. Here, FIG. 3 is a cross-sectional view of an example of this type of disk device applied to the MD, taken along a vertical cross section in the front-rear direction. As shown in FIG. 3, this disk device includes a case 11, a cartridge insertion opening 12 provided on the front surface of the case 11 for inserting an MD, and a plurality of MDs provided behind the case 11 and stacked together. And a cartridge stocker 13 for storing the same. The stocker 13 is formed by stacking four cartridge storage portions 131 each storing one MD.

A drive unit 14 for recording / reproducing an MD is provided at the lowermost front portion inside the housing 11. As shown in FIG. 4 (enlarged side view of the drive unit 14), a disc-shaped turntable 141 that rotationally drives the disc 2 in the MD is provided on the upper surface side of the drive unit 14. Since the turntable 141 is formed to have the same thickness as the depth of the spindle hole 5 of the MD, the lower surface position of the turntable 141 is a mounting surface 142 for mounting the MD. In addition, a support portion 143 that supports the holder H and the MD is provided on the upper surface of the drive unit 14 so that the top of the support portion that supports the MD constitutes a mounting surface 142 together with the lower surface of the turntable 141. (Figure 1).

Further, the MD is held upward in the direction of the mounting surface 142 of the drive unit 14 (FIG. 3), and the MD is moved forward and backward with respect to the drive unit 14 and conveyed between the insertion opening 12, each storage unit 131, and the drive unit 14. A cartridge holder H is provided. As shown in FIG. 5 (left side view of the holder H), the holder H includes a chassis 21, a guide 22 that holds the MD slidably in the front and rear, and a MD attached to the chassis 21 so that the MD can be placed inside and outside the holder H. And a roller 23 for conveying.

Of these, the guide 22 is formed with a holding surface 221 that holds the lower surface of the MD, which is the side surface on the drive unit 14 side. Further, as shown in FIG. 5, the roller 23 is attached to two roller shafts 24 rotatably provided on the chassis 21 so as to rotate integrally with the roller shafts 24. Since both ends of the roller shaft 24 are supported by the tip of the support arm 25 having the rotation fulcrum 27 on the chassis 21, the roller shaft 24 is vertically movable on the chassis 21. Further, since the support arm 25 supporting the roller shaft 24 is biased downward by the spring 26, the roller 23 attached to the roller shaft 24 biases the MD downward in the holding surface 222 direction. is doing.

The holder H moves up and down with respect to the drive unit 14 by moving up and down, and the MD is attached to and detached from the mounting surface. The drive unit 14 and the holder H constitute a cartridge mounting device for mounting and dismounting the MD on the drive unit 14.

According to the disk device having the above-described configuration, the holder H holds the MD and conveys it between the insertion opening 12, each storage portion 131, and the drive unit 14, so that the holder H is firstly inserted from the insertion opening 12. It is possible to store a plurality of MDs that have been sequentially inserted in the stocker 13 and carry one of the desired MDs by the holder H to the drive unit 14 for recording / playback. At this time, the cartridge mounting apparatus sets the MD in the drive unit 14 while holding the MD in the holder H.

[Problems to be solved by the device]

 However, in the conventional cartridge loading device, when the drive unit of the cartridge is loaded, the holding surface 221 of the guide is configured to be located on the same surface as the loading surface 142 of the drive unit. In order to stabilize the cartridge, there is a problem that a pressure contact mechanism for pressing the cartridge onto the drive is especially required. For this reason, the structure of the cartridge mounting device is complicated and the number of parts is increased.

The present invention has been proposed in order to solve the above-mentioned problems of the prior art, and an object thereof is to provide a cartridge mounting device that does not require the special pressure contact mechanism.

[0011]

[Means for Solving the Problems]

 To achieve the above object, the cartridge mounting apparatus of the present invention is the cartridge mounting apparatus having the structure as in the conventional example, wherein the holding surface of the guide is the drive unit of the drive unit when the drive unit of the cartridge is mounted. It is characterized in that the drive unit is located closer to the drive unit than the mounting surface.

[0012]

According to the present invention having the above-described structure, the holding surface of the guide is located closer to the drive unit than the mounting surface of the drive unit when the drive unit of the cartridge is mounted. Therefore, the cartridge, which is biased by the roller in the direction of the holding surface, is separated from the holding surface that was in pressure contact with the cartridge before mounting, and instead is pressed in contact with the mounting surface to be stable. The press contact mechanism is unnecessary.

[0013]

【Example】

 An embodiment in which the cartridge mounting device of the present invention is applied to an MD disc device will be specifically described below with reference to the drawings. The same members as those in the conventional example shown in FIGS. 2 to 5 are designated by the same reference numerals, and the description thereof will be omitted.

(1) Configuration of the Embodiment ... FIG. 1 The cartridge mounting device of the present embodiment is used in an MD having the same configuration as the conventional example, and has substantially the same configuration as the cartridge mounting device of the conventional example. However, when the MD drive unit 14 is mounted (FIG. 1), the holding surface 221 of the guide 22 is located closer to the drive unit 14 side than the mounting surface 142 of the drive unit 14.

Note that such positioning can be easily performed by changing the cam shape of the corresponding portion at the time of mounting when the holder H is moved up and down by the cam means (not shown).

(2) Actions and effects of the embodiment ... FIG. 1 In the present embodiment having the above-mentioned configuration, the MD is conveyed from the insertion opening 12 and the respective accommodating portions 131 onto the guide 22, or on the guide 22. When it is sent out from, the roller 23 rotates in the forward and reverse directions to drive the MD. Since the MD is urged downward by the drive roller 23, the lower surface of the MD is in pressure contact with the holding surface 221 of the guide 22 except when it is mounted (FIG. 5).

On the other hand, when mounting the MD on the drive unit 14, the holder H is lowered while holding the MD, and the MD is set on the drive unit 14. At this time, since the holding surface 221 of the guide 22 is located below the mounting surface 142 of the drive unit 14 on the drive unit 14 side, the MD urged downward by the roller 23 is as shown in FIG. In addition, since it is separated from the holding surface 221 that was press-contacted before mounting, and instead press-contacts the mounting surface 142 to be stable, no special press-contact mechanism is required. Therefore, it is possible to simplify the configuration of the cartridge mounting device and reduce the number of parts.

(3) Other Embodiments The present invention is not limited to the above embodiments, but includes the following other embodiments. For example, the holder in the present invention moves back and forth with respect to the drive unit, but this forward / backward movement is not limited to the absolute forward / backward movement of the holder, and the forward / backward movement of the drive unit relative to the holder causes the holder to move relative to the drive unit. Including the case of moving back and forth relatively. Therefore, the cartridge mounting apparatus of the present invention may be configured to raise the drive unit 14 as well as lower the holder H during the mounting.

Further, the cartridge mounting apparatus of the present invention may be provided with fixing means for fixing the holder H and the drive unit 14 at the time of mounting. That is, if the pin is provided on the side surface of the holder H and the drive unit 14 is provided with a hook that can be engaged with and disengaged from the pin, the stability of the entire holder H on the drive unit 14 is further improved. In addition, the cartridge mounting device of the present invention can be implemented such that the mounting surface is provided on the lower surface side of the drive unit and the cartridge holder is located below it.

Further, the present invention can be applied not only to the disk device configured as in the above embodiment, but also to the following disk devices. That is, the cartridge stocker is provided in the front of the housing, and the front surface of the housing is provided with a plurality of cartridge insertion openings for inserting the MDs into the respective cartridge storage portions of the cartridge stocker. Although a disk device provided at the rear is conceivable, the cartridge holder of the present invention can be used for such a disk device.
