JPS6083252A - Disk presence and absence detector of automatic player - Google Patents

Abstract

PURPOSE:To confirm whether a disk is present or not where the disk is returned to a stocker by utilizing the generation of the difference in the stroke of an arm according to whether the disk is present or not. CONSTITUTION:A shaft 48 fixed to a rotating arm 52 is fitted to a presence and absence detection arm 34. The rotating arm 52 is rotatable around the center of the 2nd shaft 53. Further, a trigger lever 40 is arranged thereunder and rotatable while fitted to the 2nd shaft 53, so the trigger lever is normally pressed against the rotating arm 52 by a torsion spring 51. When there is no disk where detection is performed, the shield part 41 of the presence and absence detection arm 34 enters the gap of a transmission type photosensor 44, so the output of the photosensor 44 is OFF, but when there is a disk, on the other hand, a front end part 56 abuts on the end surface of the disk to inhibit the subsequent rotation, so the output is still ON. Thus, whether there is the disk or not is detected.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an automatic performance device that takes out a target disc from a stocker in which a plurality of discs are stored and performs the performance. Mind regarding the bi-detecting device.

[Background of the invention]

When the target disc is taken out from the conventional stocker that stores mantissa discs, played, and taken out again When it is taken out.

If another disk is inserted from outside by the user,
Alternatively, if for some reason the ejector is moved to a different location from where it was ejected, the disc in the ejector may be pushed into a location where a disc is already in, resulting in damage to the disc.

[Purpose of the invention]

The object of the present invention is to remove the disk from the force of the stone, and when trying to return the disk to the stocker again.
An object of the present invention is to provide a detection device for confirming the presence or absence of an rK disk.

[Summary of the invention]

Before inserting a disc into the stocker, extend the stocker arm from the ejector.

If there is a Tinuku at that location, the arm will hit the end of the disc, and if there is no Tinuku, it will not hit, so by detecting the difference in stroke, it is possible to confirm the presence or absence of a disc.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 to 9.

FIG. 1 is an external view of an embodiment of C1) autochanger. 7 is a decorative front panel molded from a synthetic resin case or die-casting, 3 is an operation knob for operating the device, 4 is a display section that shows the operating status of the device, and 5 is a power source.

This is a power switch that turns off. Further, 1 is a door for taking in and taking out a stocker, which will be described later, and 2 is a manual stocker, which will be described later.

FIG. 2 is a perspective view of the mechanism. Reference numeral 8 denotes a stocker, which has an oil-shaped shape with an opening at the bottom, and stores 30 disks at regular intervals so that the recording area and label surface face each other. FIG. 6 shows a sectional view of the stocker 8. Arrow A indicates the aforementioned opening 64, and one stopper 11 is attached to every 74,721 disks at ① to prevent the disk 10 from falling from the opening. There is a slit 33i under the stopper.

A perspective view of the sheet is shown in FIG. 4, and one hole corresponding to each of the 74,721 sheets has been cut out. Also.

There is a handle 9 on the first side of the stocker 8, and by holding the handle 9 and pulling the force 8 out of the device, the stocker 8 can be operated for 4 hours and 7 hours.

You can also replace the stocker with another stocker.

In FIG. 2, a manual stocker 2 is provided next to the stocker 8. The manual stocker 2 has a structure similar to that of the stocker 8, which is combined with the part 14 and separated from one disc, and has a stopper 11 and a sulin) 3.
3' Momo. 14 is fixed to the jersey, or the manual stocker 2 is slid on the rail 22 [7
;C is on, and a spring gives it a knife to try to come out to the 70-nod panel side, but the a-lock lever 16 prevents it from jumping out. Operation control +6 k From this point, the manual stocker 2 is moved up to '1ila [-N, so the solenoid 15 pulls up the a lever 16, and the manual stocker 2 jumps out with the force of by.
8 With this, 747 other than those in stocker 8
By inserting and pushing the 21 sheets through the opening on the top surface of the manual stocker 2, the disks can be rearranged in the same shape as the disks in the stocker 8. A carrier 17 is rearranged under the stocker 8 for loading and unloading a target disc from the stocker 8 or the manual stocker 2, and for loading and unloading a disc onto a transport player by the player 211.

The carrier 17 is fixed to a part of the belt 20 hung on the pulleys 19-1, 19-2, and when the motor 18 rotates the goo 919-1, the belt 20 rotates and the carrier 17 moves around the kite. Rail 13-1.13-
2.Slide on top.

Next, the operation of this actual flow 0 will be explained with reference to FIGS. 2 and 5. FIG. 5 is a sectional view of the stone force 8 and the carrier 12. In fig.

In the normal state, the carrier 17 is in contact with the player 21. When the motor 18 rotates, the carrier 17 slides on the kite rail 13-1.13-2. that time,
As shown in FIG. 5, nine photosensors 28 attached to the carrier 17 detect and count the slits 33 of the machining machine 8, so that the carrier 8 detects the target disc and stops below it. Next, when the second motor 31 rotates and the °C worm 62 rotates via the second belt 69,
The worm wheel 29 now fitted therewith rotates counterclockwise. As a result, the arm 27, which was initially in the position indicating the winning position, rises to the position indicated as the central position as the bin 30 provided on the worm wheel 29 traces the inside of the kite groove 35 of the arm 27. The disk 10 in the stocker 8 is lifted by the arm 27 and moved in the direction of the arrow by the protrusion 36 in the stocker 8, and the disk 10 leaves the stopper 11. Although the bottle 60 continues to rotate, the arm 27 remains stationary because the kite groove 35 is aligned with the rotation trajectory of the bottle 300 during θ in the figure. During this time, the second solenoid 26
As a result, the shaft 24 is pulled down via the lever 25, and the stopper release lever 23 fixed to the shaft 24 rotates the stopper 11 to the position shown by the solid line. When the bin 30 continues to rotate in this state and passes through the interval θ, the arm 27 descends, and the disk 10 is also supported by this.

At a point where the upper end of the disk 10 has become almost as straight as the stopper, the solenoid 260' is turned off, and the stop flange release lever 26 and the stopper 11 return to the positions indicated by bw. The arm 27 stops at the position indicated by the dotted line, and the disk 10 is placed in the carrier 17 i'13.

Then, the motor 18 in FIG. 2 rotates, the carrier 17 moves to the player 21, and the disc 10 is moved to the player 21
It is based on and is hilarious. After playing, the carrier 17 moves and stops at the position l from which the disc 10 was taken out. Without stopping, the existence detecting arm 64 shown in FIG. 5 confirms that there is no disk in the place where the disk 1o7a' is about to be inserted. The operation of this presence/absence detection arm will be described later. After confirmation, the second motor rotates in the opposite direction to that when the disk 10 was taken out, and the worm wheel 29 rotates clockwise. As a result, the bin 60 also rotates and the arm 27 causes the disk 10 to rise. Disc top edge or stopper 11
Solenoid 26 is turned on at the point where the height is similar to that of a pigeon.
The stopper 11 is at the position shown by the solid line. Further, when the arm 11 rises and the bin 60 enters the section θ, and the solenoid 26 is set to 0FF-3- at Ibj where the arm 11 is stopped, the stopper 11 is at the position shown by the dotted line, and the disk 1
0 is prevented from falling, the disk is stopped at the stocker 8FrJ (t), and the disk 77 is stopped at the position shown by the dotted line. This completes the operation of one disk, and the carrier 17 moves to the next instructed disk and performs the same operation.
The disc placed in the manual stocker 2E shown in Fig. 2 is also operated in the same manner.

The structure and operation of the presence/absence detection arm will be explained with reference to FIGS. 6 to 9. This is because the disk is taken out from the stocker 8 or manual stocker 2 shown in Figure 2 and the carrier 17
When it is contained within.

If another disc is inserted by the user - or if for some reason the carrier 17 is placed in a different location than the one from which it was taken out - PJ'rVc
When trying to record to a JTiC disk.

Carrier 17 is placed in I9r where the disc is already stored.
This detection is performed to prevent the disc from being damaged when trying to insert it into the disc.

FIG. 6 is a top view of the one-twin self-black detection system, and FIGS. 7 to 9 are front views. First, the structure of the presence/absence detection mechanism will be explained with reference to FIGS. 6 and 7. Reference numeral 46 corresponds to the opening of the disk storage section in the carrier 17 through which the disk passes when transferring the disk to the carrier 17, the stocker 8, or the manual stocker 2. The presence/absence detection arm 64 is attached to a shaft 48 fixed to the rotating arm 52.

The rotating arm 52 rotates around the second shaft 53.
'rib. There is a tri-force lever 40 below the lever, which is held by a second shaft 53 and can be rotated; however, in a normal state, it is pressed against a rotating arm 52 by a torsion claw 51. Let me briefly explain the operation. In the normal state, the presence/absence detection arm is in the state shown by the dotted line because the rotating arm 52 is pulled by the spring 54.

When the wire 39 is pulled through the lever 38 by the solenoid 67.

IJ Force L/Bar 40 is L] ff1L,) - Rotating arm 52 is pressed 7' from spring 51Vc
Since the presence detection arm 34 rotates in the direction of the arrow in FIG. 6, the presence detection arm 34 will either rotate in the direction of the arrow in FIG. When the wire 39 is pulled further, the tri-force lever 40 rotates away from the rotating arm 52, and the protrusion 46 of the tri-force lever 40 pushes the part 55 of the presence detection arm 34, as shown in FIG. As a result, the presence/absence detection arm 34 rotates around the shaft 48, and the tip end 56 rises.If there is no disk at ffr when detection is performed first, the presence/absence detection arm 34 will move up to the position +1 shown in FIG. Rotating shielding part 41 is transparent type)
Since the photo sensor 44 enters the gap, the output of the photo sensor 44 is turned OFF, but if there is a disk, the tip of the presence/absence detection arm 34 5 as shown in FIG.
6 hits the end surface of the disk and further rotation is prevented, so the shielding part 41 does not enter the gap of the transmission type photosensor 44 and the output is 07V - 1'-f. As a result, the presence or absence of the disk is detected, and then when the solenoid 37 turns OF1', the presence/absence detection arm 34 returns to the position indicated by the dotted line in FIG.

45 in Figure 9 and 46 in Figure 10 are actually rfed on the same axis of @49, but they are divided into two diagrams for explanation. The first cam 45 in FIG. 9 is for detecting the stop position of the arm, and there is a dent in a part of the outer circumference of the first cam 45, which is detected at the point where the first microphone 47 freezes. A 427 shown in FIG. 5 is at the position indicated by the dotted line. Sweet. In Fig. 10, yI#, 2 cam 46 turns ON the solenoid 26 of supply 5〆1, 01? This is to detect the F timing, and the part indicated by 50 of the second cam 46 or the second

〔Effect of the invention〕

From the above, according to the present invention, f'L, when a disk is removed from the carrier to the stocker and the disk at the location where it is to be returned is detected, another disk is inserted. This prevents the disk from being pushed into the area where it is placed, causing the disk to become cluttered.
