Summary of the invention

The object of the invention provides a kind of high-density drawing-type CD cassette, and its volume is little, more saves material, and the CD of unit volume storage is more.

Technical scheme of the present invention is: a kind of high-density drawing-type CD cassette, comprise the cassette box of an end opening and be slidingly connected to the interior some optical disc trays of cassette box, described each optical disc tray is provided with at least one pull tongue in the front end of extracting direction out, the setting of staggering in the horizontal direction of the pull tongue of described some optical disc trays.

When original mechanical arm is taken out dish device extraction optical disc tray, the position difference only is the thickness of an optical disc tray between the pull tongue of adjacent two optical disc trays, in order to make mechanical arm take out the extracting objects optical disc tray that the dish device can be correct, the accuracy requirement of mechanical arm assembly is just than higher; And the present invention has converted the demanding little spatial vertical of original degree of accuracy location the mechanical positioning than large space of horizontal direction to, and the accuracy requirement reduction to mechanical arm assembly has reduced processing cost.Simultaneously because the pull tongue has moved on to the front end of optical disc tray from the side of original optical disc tray, therefore mechanical arm is taken out the dish device when front end pull optical disc tray, the stressed direction of optical disc tray is better, and optical disc tray is not yielding, and that therefore optical disc tray can be done is thinner.Thereby reduced the material use cost, simultaneously also attenuate the thickness of CD cassette.

Further, in the above-specified high density drawing-type CD cassette, described each optical disc tray front end is provided with two pull tongues of horizontally separated setting, and the level interval on described each optical disc tray between two pull tongues equates.Mechanical arm is taken out on the dish device and also is provided with two pull pawls accordingly with two pull tongues, and is separately stressed, and making mechanical arm take out the dish device can extract optical disc tray or push out very stably.

Further, in the above-specified high density drawing-type CD cassette, described pull tongue is provided with the pull hole of taking out dish device pull for mechanical arm.The pull pawl that mechanical arm is taken out the dish device at first stretches in the pull hole, optical disc tray is extracted out again.

Further, in the above-specified high density drawing-type CD cassette, described optical disc tray is the plane in the rear end of extracting direction out, and the described cassette box rear end relative with opening is provided with the rear end cap parallel with opening.Because optical disc tray of the present invention is thinner than common optical disc tray, the number of the optical disc tray that is provided with in each CD cassette of the present invention simultaneously also lacks than the general optical disk casket, such as ten, so the thickness of CD cassette of the present invention is thinner than the CD cassette of prior art, therefore the very convenient user's grasping of this thickness does not need to be provided with in cassette box back to hold handle again again, thereby makes the length of cassette box of the present invention shorten yet, further, the length of optical disc tray has also shortened.Thereby reduced the use of material, further reduced the volume of CD cassette simultaneously, improved the storage density of unit volume CD.

Further, in the above-specified high density drawing-type CD cassette, the rear end of described optical disc tray is provided with latch hook, and described cassette box rear portion is provided with can be with respect to the slip buckle of cassette box slip, and described slip buckle is provided with the sticking department that cooperates snap close with latch hook.When CD cassette takes out from CD server, then promoting the slip buckle makes sticking department and the latch hook on the optical disc tray on it lock, this moment, all optical disc trays all can't be again slide with respect to the cassette box, and optical disc tray is deviate from and caused the CD of the inside to drop when avoiding picking and placeing CD cassette.

Advantage of the present invention is:

1, the present invention moves on to the front end of optical disc tray with the pull tongue from the side of optical disc tray, corrected by force direction when making the pull optical disc tray, thus optical disc tray can be done thinner, reduced the volume of CD cassette.

2, the cassette box of the present invention optical disc tray that can hold is less, and optical disc tray of the present invention is thinner simultaneously, so the thin thickness of cassette box, making things convenient for the user to hold picks and places, therefore do not need to be provided with to hold handle, simplified the design of cassette box, shortened the length of cassette box and optical disc tray simultaneously.
