Description

The present invention relates to a device for storing discs of

  information storage comprising at least one mobile storage magazine of said disks, in particular in a system for reading and / or writing and / or storage of disks. Such a device allows quick access to the data contained in said disks.

  Prior Art: There are disk storage and reading devices in which the stored disks are arranged circularly about an axis. Each disc is held in this circular magazine by a lock. This lock is disabled or forced when inserting or ejecting a disk. Each disk storage and reading device has a device for reading and / or writing disks. Said member receives a disc or a disc is taken from said body by means of a gripping arm, such as a gripper arm used in some storage devices and reading discs. Once the disk is held by this arm, the arm moves the disk from its location to a desired area of the disk storage and reading device (either to the drive, to the magazine, or to the output area disks, either to the input area of the disks). The arm may have complex movements allowing the disks to be dropped or taken in multiple positions depending on the type of disk storage and reading device. Each disk, thus stored, has a specific place in the store to be identified by a control system composed in part of a microprocessor and a program adapted to manage the storage and reading device. discs. This control system will be named in the description of the invention, management system of the device for storing and reading discs.

  As previously explained, the storage and reading devices for circular magazine discs can not do without a transfer member and / or removal and / or taking discs to move and / or deposit and / or or take a disc to a desired area. This arm takes a significant part in the manufacture of this type of storage device and reading discs.

  Indeed, this arm obeys important manufacturing tolerances to ensure a precise displacement of the discs.

  In addition, the arm must embark a member intended for him, the setting and / or removal of the disc. This body must be able: At first, be fine enough to interpose between the disks stored in the store.

  Then, in a second time, this organ must deploy without touching the other disks stored in the store, in order to take and / or deposit the disk in the desired area.

  Thus, the fact that the current circular disk storage and reading devices can not operate without this arm, whose function is the displacement and / or the setting and / or the removal of disks, shows the importance of this organ. .

  But this: organ, on the one hand, complicates the entire device for storing and reading circular discs. On the other hand, this arm imposes a large total footprint on circular disk storage and reading devices. Finally, this arm has an unavoidable cost that is reflected in circular disk storage and reading devices.

  OBJECTS OF THE INVENTION The object of the invention is to remedy all or some of the above disadvantages, in particular, problems of simplification of the design, size and cost of manufacturing the arm.

  Fig. 8 is an isometric view describing through detail H the holding of a disc (701) by a separator (702). This separator (702) is composed of four lugs (704) and a retaining tab (703).

  With reference to these drawings, the invention is described as follows: The device Figure 1 provides a first member for inserting and / or extracting disks. This first element is called input / output element (100). The input / output member (100) in FIG. 2 allows the user to insert discs into the drum (205) of the magazine (200) or to eject discs from the drum (205) of the magazine (200) to the magazine (200). the user. This element (100) is provided with a disk gripping means composed of a conical roller (105) and a cylindrical roller (106) but also of an electric motor (101) rotating the rollers in order to introduce and / or eject said discs.

  This first organ therefore interacts with the magazine (200). This store (200) has three positions, shown in Figure 4, respectively named: position input / output named (A), allowing the insertion and / or extraction of disks, such as the disc (212) of the figure 5, at the input / output member, then the named selection position (B), for selecting disks and / or disk locations, and finally the named Read / Write position (C) for presenting and / or receiving disks, such as the disk (209), at the read / write device. The three aforementioned positions of the magazine (200) are made using a geared motor (201) whose function is the translation of the magazine (200). The selection of the disks of the magazine (200) is carried out by the motor (202) ensuring the rotations of direction (D) or (E) of the drum (205) of the magazine (200).

  The selection of disks is thus achieved by means of the electric motor (202) mounted with a pulley (203) on a belt (204). The geared motor (201), its own function to move the magazine (200) to the input / output member (100) and / or the read / write member (300).

  Keeping the discs in position in the drum (205) such as the disc (701) Figure 8 is done through the tongue (703) located on the side of the disc separator (702). Each disc separator, such as the separator (211) or the separator (213), is held in position by its four cylindrical ends (704) mounted in the holes of the drum (205) provided for this purpose. Each tongue, such as the tongue (703), exerts a force calculated to ensure that the disk (701) is held in the drum (205) of the magazine (200).

  This store (200) therefore interacts with the read / write device (300). This member (300) makes it possible to introduce and / or extract disks from the drum (205) of the magazine (200). But this member (300) also reads / writes discs from the drum (205). The read / write member (300) is used to insert disks from the drum (205) of the magazine (200) to the read / write device (300) or to eject disks from the read / write device. Writing (300) to said drum (205). This gripping function is provided by a conical roller (305) and a cylindrical roller (306) fixed in front of the reading / writing member (308). The electric motor (301) rotates said rollers.

  As illustrated in Figure 1, the Input / Output member (100), the magazine (200) and the read / write device (300) are aligned.

  The device according to the invention operates as follows when a user wants to introduce a disk in the present invention in order to read the information contained therein.

  In the most unfavorable case where the disk to be read comes from the zone furthest away from the read / write device (300), in this case at the input / output device (100), displacements are made only along two axes. A first translation axis makes it possible to move the magazine (200) from the position (A) to the position (C) and aimed and reversed, in order to move the disc. A second axis of rotation makes it possible to position the disk either in front of the input / output member (100) or in front of the reading / writing device (300). In this case, the first rotation will aim to position an empty disk housing in front of the input / output member (100). The second rotation will aim to present the user's disk (the disk slot occupied by the user's disk) in front of the read / write device (300). When inserting a disk, by the user, into the input / output device (100), the disk activates a sensor identical to the sensor (307) of FIG. 3 which informs a control system composed in part of a microprocessor and a program adapted for the disk storage and reading device.

  This management system then sets the motor (101) which drives the belt (102) and then the pulley (103), which in turn, drives the pinion (104) connected to the roller (105), I) as soon as the user contacts the disc with the pair of rollers (105) and (106), the disc is then driven by said pair of rollers (105) and (106) and the magazine (200), previously placed in the Input / Output (A) position, then presents an empty disk slot, composed of two separators, such as the disk separators (211) and (213), to receive the disk of the user such as the disk ( 212).

  Since it is established that the magazine (200) can contain several disks, it is then possible that there is a disk before and after the disk of the user, as respectively, disks (210) and (214) figure 5, and these discs (210) and (214) are then found on either side of the rollers (105) and (106) of the input / output member (100). Therefore, the size of the rollers (105) and (106) of the input / output member (100) is calculated to not touch any of the disks, such as disks (210) and (214), present in the drum (205) of the magazine (200).

  The sizing of the rollers (105) and (106) therefore allows a disc to be stored (undoubtedly inserting and / or extracting a disc in a disc housing) very tightly in the drum (205) allowing the drum (205) inserting the rollers (105) and (106) into a disk housing by not touching the disks on either side of the desired disk housing.

  Maintaining the user's disc such as the disc (212) in the drum housing (205) formed by two separators, such as the separators (211) and (213), is provided by a tongue, such as the tongue (703 ), located on the back of each separator. This tongue (703) exerts a force equal to or greater than several times the mass of said disk so as to ensure the maintenance of said disk.

  Once the disc of the user, such as the disc (212), inserted in the housing of the drum (205) formed by two separators, the geared motor (201) is then switched on by the management system of the device. storing and reading discs to move the magazine (200). The translation of the magazine (200) is made possible on the one hand, because the geared motor (201) being the stationary part of the magazine (200) can only move the moving part of the magazine (200). In addition, the geared motor (201) rotates the pinion (208) driving in translation the rack (207) itself connected to the movable portion of the magazine (200). The magazine (200) is found, therefore, therefore, driven in translation by the geared motor (200).

  Once said magazine (200) in the selection position (B), as shown in Figure 6, the management system gives the order to stop the geared motor (201). At this time, the management system gives the command to start the motor (202) to rotate the drum (205) and thus, therefore, position the user's disc in the axis and in front of it. of the reading / writing organ (300). As soon as the disk of the user is in the axis and in front of the read / write device (300), the management system gives the order to stop the motor (202).

  This rotation of the drum (205) is performed arbitrarily in the direction (D) or (E) of the drum (205). Indeed, the direction does not matter here, since the disk of the user is equidistant from the read / write member (300).

  The choice to rotate direction (D) or (E) only affects the travel time of the disc to the reading / writing member (300), when the selected disc, from the discs of the drum (205) , is located on either side of the translation axis of the magazine (200). In the case above, the rotation of direction (D) or (E) is determined according to the shortest distance to be traveled by the chosen disc.

  The disk of the user is found in the axis and in front of the reading / writing device (300). In order to be able to insert the user disk into the read / write device (300), the geared motor (201) is restarted by the management system in order to translate the magazine (200). During the translation of the magazine (200) direction (B) to (C), that is to say, from the magazine (200) to the reading / writing device (300), the disk of the user will be introduced into the pair of rollers (305) and (306) of the read / write member (300).

  Since it is established that the magazine (200) can contain several disks, it is also possible, as in the case of the input / output device (100), that there is a disk before and after the disk of the disk. The user thus respectively disks (217) and (218) are then found on either side of the rollers (305) and (306) of the read / write member (300). Therefore, the size of the rolls (305) and (306) of the read / write member (300) is calculated to not touch any of the disks, as in the case of the rolls (105) and (106) of the input / output member (100).

  The sizing of the rollers (305) and (306), such as the rollers (105) and (106), therefore makes it possible to store discs (namely inserting and / or extracting discs in a disc housing) in a very tight manner in the drum (205) allowing it to introduce the rollers (305) and (306) into a disk housing by not touching the disks on either side of the desired disk housing.

  Once the magazine (200) has arrived in the read / write position (C), FIG. 7, allowing insertion of the user disk, such as the disk (209), into the read / write device (300). , the management system gives the order to stop the geared motor (201). In order to move the user's disk from the drum housing (205), formed by two separators, such as the separators (215) and (216), to the read / write member (300), the pair of rollers (305) and (306) are started with the motor (301) by the management system of the disk storage and reading device.

  The pair of rollers (305) and (306) making a sufficiently large pressure on the user's disk, such as the disc (209), makes it possible to extract, without any difficulty, the disc of the user maintained by a tongue, such as the tongue (703). The user's disk being driven by the pair of rollers (305) and (306), the disk of the user is therefore found in the reading / writing device (308).

  The user can thus have access to the information contained on his disk.

  The device according to the invention also functions as follows when a user wants to output a disk of the present invention without reading the data it contains: During this operation, the management system of the storage and reading device of disk uses the magazine (200) and the input / output device (100). Once the user's disk has been selected, the management system rotates the drum (205) and stops to place the user's disk in the axis and in front of the input member. / Output (100) then translates from (B) to (A) of the magazine (200) by means of the geared motor (201). Once the user's disk is in the rolls (105) and (106) of the input / output member (100), the rollers (105) and (106) are activated to extract the drum disk (205) of the magazine (200) to the user. The user can therefore recover the previously selected disk.

  Finally, the device according to the invention operates as follows when a user wants to store a disk in order to later retrieve the information contained in the disk.

  During this operation, the management system uses the store (200) and the input / output member (100). Once a disk slot for the user's disk is assigned by the management system, the management system gives the order to rotate the drum (205). This rotation makes it possible to present the chosen housing, for the disk of the user, in the axis and in front of the input / output member (100).

  As soon as the housing selected for the user's disk is in the axis and in front of the input / output member (100), the rotation is stopped by the management system which then gives the order of moving the magazine (200) to the input / output member (100). Once the magazine (200) is in the Entry / Exit (A) position, the user can then place his disk in the rollers (105) and (106) so that these rollers insert the user's disk into the housing chosen by the management system. Once the user's disk is placed in the drum (205) by the rollers (105) and (106) and held by the tongue, such as the tongue (703), the management system gives the order to move the magazine (200) to the selection position (B).

  When the user wants to recover his disk, the management system will then perform the above described output operation of a desired disk, to remove the disk requested by the user.

  As the above-mentioned elements demonstrate, the use of a pair of rollers as a plug and / or disk deposit used in the invention presented for the Input / Output (100) and Read / Write (300) functions. as well as the use of the magazine (200), make it possible to remedy all or part of the disadvantages of the previous disk storage and reading device management systems using an arm to carry out these same operations of taking and / or removing and moving disks.

  Indeed, the invention presented makes it possible to reduce the cost of manufacturing a storage device management system and disk reading thanks to the low cost of manufacturing and designing a system using rollers to replace the functions performed by the arm of the previous storage device management systems and disk reading.

  In addition, the invention presented also makes it possible to reduce the total size of a storage and reading system for circular magazine discs thanks to the small bulk of the rollers.

  Finally, the invention presented also makes it possible to reduce the time between the insertion moment and the reading / writing moment of the disc thanks to the alignment of the axes of the input / output member (100), the magazine ( 200) and the read / write device (300). This alignment makes it possible to perform the operations necessary to read and / or write a disk, after the insertion of a disk, faster than the previous storage device management and disk reading systems. The device according to the invention is particularly intended for storage and / or reading / writing of disks.

  Of course, the design of the management system of the storage device and disk reading that uses a microprocessor control system and whose creation is within the reach of the skilled person is not part of the invention.

  It is obvious that the invention described above is not specifically limited to the description described and shown but various modifications and changes can be made to this application without departing from the spirit and scope of the invention. .
