  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a configuration block diagram of a data recording device (duplicator) 1 in the present embodiment. Conventionally, a plurality of recording media are mounted on the main board, or an expansion board is connected to the main board, and a plurality of recording media are mounted on the expansion board. A board 10, a subunit board 12, and a slot board 14 are provided.

  The main board 10 is a circuit board that controls the entire apparatus, and the data recorded on the copy source recording medium regardless of the type of the copy source recording medium, the copy destination recording medium, or the type of data to be copied. And a signal processing circuit for generating data to be recorded on the copy destination recording medium. The signal processing circuit includes a ROM 10c in which a program (firmware) for processing data is stored, a RAM 10b as a working memory, and a CPU 10a. The CPU 10a, RAM 10b, and ROM 10c are each connected to a CPU bus. The signal processing circuit includes a connector 10d. The connector 10d is a connector for connecting to a subunit board 12 described later, and is connected to the CPU bus.

  The copy source data is supplied to the CPU 10 a of the main board 10. The CPU 10a appropriately performs signal processing according to the firmware stored in the ROM 10c, and outputs it to the subunit board 12 described later via the connector 10d. The copy source data is read from a recording medium mounted in a copy source recording medium slot provided in the duplicator 1. The copy source data may be supplied from the outside. For example, a personal computer may be connected to the duplicator 1, and data recorded in a storage device of the personal computer, for example, an HDD may be supplied to the main board 10 as copy source data.

  The type of copy source data is arbitrary, and may be any of text data, audio data, image data, moving image data, program data, and the like. However, the main board 10 processes the copy source data as an image file in order to speed up the processing.

  Also, the type of the copy source recording medium is arbitrary, but basically, the type of the copy source recording medium and the copy destination recording medium are preferably the same. For example, both the copy source recording medium and the copy destination recording medium are USB memories. However, the present embodiment is not limited to this, and the types of the copy source recording medium and the copy destination recording medium may be different. For example, the copy source recording medium is a USB memory, and the copy destination recording medium is an SD memory or the like.

  The sub unit board 12 is detachably connected to the main board 10 and includes a signal processing circuit for performing signal processing in accordance with the type of the copy destination recording medium. The signal processing circuit includes a FIFO memory 12d, serial / parallel conversion circuits (S / P circuits) 12e and 12f, and connectors 12g, 12h, and 12i in addition to an FPGA (Field Programmable Gate Array) 12a, a RAM 12b, and a ROM 12c.

  The FPGA 12a performs signal processing according to the type of the recording medium of the copy destination based on the operation content defined by the CPU 10a of the main board 10. For example, when the copy destination recording medium is a USB memory, a command according to the USB memory standard transmitted from the CPU 10a of the main board 10 is interpreted and executed. Note that the FPGA 12a may be replaced with a CPU, and the signal processing circuit on the subunit board 12 may be controlled in accordance with the firmware stored in the ROM 12c.

  The FIFO memory 12d stores the copy source data transmitted from the main board 10 and buffers it based on the principle of pre-read-first-out.

  Serial / parallel conversion circuits (S / P circuits) 12e and 12f convert the parallel copy source data into serial data and output the serial data.

  The connector 12g is connected to the connector 10d of the main board 10. The connectors 12f and 12i are connected to connectors of a slot board 14 described later.

  In this embodiment, the serial data output from the serial / parallel conversion circuit (S / P circuit) 12e is supplied from the subunit board 12 to the slot board 14 via the connector 12h, and the serial / parallel conversion circuit (S / P). The serial data output from the circuit) 12f is supplied from the subunit board 12 to the slot board 14 via the connector 12i, which is divided into two in consideration of the number of slots mounted on the slot board 14. There may be only one serial / parallel conversion circuit (S / P circuit) and connector, or three or more.

  The slot board 14 is detachably connected to the subunit board 12, and connects the plurality of slots 14c and connectors 14a and 14b for mounting the copy destination recording medium and the slots 14c and the connectors 14a and 14b. Signal lines.

  The connector 14a is connected to the connector 12h of the subunit board 12, and the connector 14b is connected to the connector 12i of the subunit board 12. The copy source data from the main board 10 is converted into serial data by the serial / parallel conversion circuits (S / P) 12e and 12f of the sub-unit board 12, and the slot is formed through the connector 12h and the connector 14a, and the connector 12i and the connector 14b. It is supplied to each slot 14 c of the board 14. Copy source data is supplied in parallel to each slot 14c via connectors 12h, 12i, 14a, and 14b.

  The slot 14c is a slot having a shape corresponding to the type of the recording medium. For example, a recording medium such as a USB memory or an SD memory is attached to the slot 14c. The number of the slots 14c is arbitrary, but can be 10 for example.

  As described above, the duplicator 1 of the present embodiment divides the function into three instead of the conventional single main board, and divides the function into three, the main board 10, the subunit board 12, and the slot board 14. It can be said that each is detachably connected. The slot board 14 is basically mounted with only the slot 14c corresponding to the recording medium. Even if an abnormality or failure occurs in the slot 14c, it is not necessary to replace the main board 10, and the slot board 14 It is only necessary to replace the slot board 14 by disconnecting it from the subunit board 12 at the connector portion.

  Further, when changing the type of the recording medium of the copy source, for example, when changing from the USB memory to the SD memory, the subunit board 12 and the slot board 14 are separated from the main board 10 at the connector portion, and the type of the recording medium is respectively set. What is necessary is just to replace | exchange for the subunit board 12 and the slot board 14 according to. For example, when the copy destination recording medium is changed from USB memory to SD memory, the subunit board 12 is changed from USB to SD memory, and the slot board 14 is changed from USB memory to SD memory. is there. In this embodiment, even when the type of the copy destination recording medium is changed, the main board 10 does not need to be changed and can continue to be used as it is.

  The replacement of the subunit board 12 is performed with the power of the duplicator 1 turned off. After the subunit board 12 is replaced, the CPU 10a of the main board 10 acquires information on the type of the subunit board 12, and the subunit board 12 is replaced. Processing according to the 12 types is executed. That is, the CPU 10a of the main board 10 executes data processing and commands defined in the USB memory standard if the subunit board 12 is for USB, and the SD memory standard if the subunit board 12 is for SD memory. Executes data processing and commands specified in. The CPU 10a of the main board 10 acquires information about the type of the subunit board 12 each time in the startup process after the duplicator is powered on. The duplicator 1 may be provided with a dip switch for manually setting the type of recording medium to be copied. When the subunit board 12 is a composite board corresponding to a plurality of types of recording media, the type of the replaced slot board 14 is detected electrically or mechanically, and the data processing and commands to be executed are switched. . In the case of a composite board, since a plurality of connectors corresponding to the type of recording medium are mounted on the subunit board 12, a connector connected to the slot board 14 is detected from the plurality of types of connectors (for example, the connector By detecting conduction / non-conduction, the type of the slot board 14 can be electrically detected. Of course, an identifier may be provided on the slot board 14, and the type of the slot board 14 may be detected by reading it with a sensor or by mechanically switching it by providing a dip switch or a detection switch. It is not limited.

  FIG. 2 shows an external perspective view of the duplicator 1. Various operation panels 15 and a power switch are arranged on the front surface of the duplicator 1, and a slot 16 for mounting a copy source recording medium and a slot board 14 and a slot 14c for mounting a copy destination recording medium are provided. Be placed. A plurality of slot boards 14 in the vertical direction in the figure, and five in the figure are installed in parallel. When the number of slot boards 14 to be installed is four or less, a dummy panel is installed on the front surface of the empty space (in front of the duplicator 1), thereby closing the empty space. In each slot board 14 to be installed, a plurality of, in the figure, ten slots 14c are arranged in the horizontal direction. Therefore, in the duplicator 1 in the present embodiment, up to 50 slots 14c can be arranged, and a recording medium can be mounted in each of the 50 slots 14c. As described above, the copy source data is supplied in parallel to the recording medium mounted in the slot 14c, and the copy is executed in parallel. Then, copy verification is performed for each recording medium, and the verification result is displayed for each recording medium. For example, a USB memory is installed in the slot 16 as a copy source recording medium, and for example, a USB memory is installed in each slot 14c as a copy destination recording medium.

  When a USB memory is installed as a copy source recording medium in the slot 16, the CPU 10a of the main board 10 reads data stored in the copy source USB memory and stores it in the RAM 10b. Then, the data is supplied to the subunit board 12 as copy source data (copy data) via the connectors 10d and 12g. The copy data is stored in the FIFO memory 12d of the subunit board 12, sequentially read out, converted into serial data by the serial / parallel conversion circuits 12e and 12f, and the data of the slot board 14 via the connectors 12h, 12i, 14a and 14b. Supplied to each slot 14c and recorded in a USB memory attached to each slot 14c. Copying is executed in parallel for each slot 14c. When the copy of the copy data is completed, the CPU 10a of the main board 10 next executes a verification process on the USB memory mounted in each slot 14c. This verification process is also executed in parallel for each USB memory in each slot 14c. If the result of the verification is normal, it is determined that the copy has been completed normally, and if it is abnormal, it is determined that the copy has not been completed normally. When completed normally, the LED 17 provided in the vicinity of the slot is lit in green. On the other hand, if it is not completed normally, the LED 17 is lit red. Therefore, by visually recognizing the color of the LED 17, the user can easily confirm the slot that has been normally copied and the slot that has not been normally completed.

  A plurality of duplicators 1 can be cascade-connected as necessary. Therefore, for example, when copying to 100 USB memories, another duplicator is connected to the duplicator 1, and copy data is supplied in parallel to each slot 14c (100 slots in total).

  FIG. 3 shows an external perspective view of the slot board 14 removed from the subunit board 12 of the duplicator 1. FIGS. 4A, 4B, and 5 are external perspective views of the duplicator 1 with the top cover removed. The main board 10 is erected and fixed to a predetermined position (substantially intermediate position) in the depth direction inside the housing through the bracket 11 so that the longitudinal direction is the lateral direction. The main board 10 is fixed to the back side of the bracket 11. The bracket 11 is fixed between both side walls of the housing so as to bisect the space inside the housing in the depth direction. The bracket 11 is formed with an opening into which the connector 10d of the main board 10 is inserted. The connector 10d of the main board 10 protrudes from the opening toward the front when the main board 10 is fixed to the bracket 11. To do. A cooling fan 60 is provided on the rear surface of the housing, and cools the main board 10 by exhausting air inside the housing to the outside of the housing. The back wall 50 is fixed inside the housing on the front side with respect to the main board 10, and the subunit board 12 is disposed between the main board 10 and the back wall 50. That is, the connector 12 g of the subunit board 12 is connected to the connector 10 d of the main board 10, and the opposite surface of the subunit board 12 is inserted into the opening 51 formed in the back wall 50. FIG. 4B shows a perspective view of the back wall 50. As illustrated, the back wall 50 is formed with an opening 51 corresponding to each of the plurality of subunit boards 12 into which the subunit boards 12 are inserted. The said surface of the subunit board 12 inserted in the opening part 51 of the back wall 50 is further fastened and fixed to a housing | casing by the bracket 18 shown by FIG. A pair of openings are provided in the central portion of the bracket 18, and the two connectors 12 h and 12 i of the subunit board 12 are respectively inserted into the openings and project from the openings toward the front. The opening 51 of the back wall 50 is closed by the bracket 18 that fixes the subunit board 12 to the housing of the duplicator 1. When the number of subunit boards 12 is four or less, the opening 51 of the back wall 50 to which the subunit board 12 is not attached is closed by the dummy bracket 18 (no opening). The slot board 14 is mounted in a storage chamber 52 as an independent space provided inside the housing. The back side (back side) of the storage chamber 52 is formed by a back wall 50. Since the two connectors 12h and 12i of the subunit board 12 protrude toward the front side from the opening of the bracket 18, the connectors 14a and 14b of the slot board 14 are connected to the connectors 12h and 12i of the subunit 12, respectively. Then, the slot board 14 is mounted. In the present embodiment, as described above, the main board 10 is cooled by exhausting the air inside the casing to the outside of the casing by the cooling fan 60. At this time, the bracket 18 serves as a kind of barrier and dust. Can be prevented from being sucked into the housing from the outside and adhering to the slot 14c of the slot board 14. It is preferable that the bracket 18 for fixing the subunit board 12 to the housing completely isolates the space of the slot board 14 from the inside of the housing and is in a sealed state. Since the bracket 18 is an instrument for fixing the subunit board 12 to the housing, the subunit board 12 is configured to be detachable, and the slot board 14 is configured to be detachable from the subunit board 12 so that the It becomes possible to provide a barrier between the unit board 12 and the slot board 14, and thus it can be said that the abnormality and failure of the slot due to the dust adhering to the slot board 14 due to the suction air of the cooling fan can be prevented.

  FIG. 6 is a perspective view of the main board 10, the subunit board 12, and the slot board 14 in the mounted state inside the casing of the duplicator 1. FIG. 7 shows a plan view of the main board 10, the subunit board 12, and the slot board 14 in the mounted state.

  As described above, the main board 10 is erected and arranged so that the longitudinal direction thereof is the horizontal direction in the housing. The connector 10d protrudes from the board surface of the main board 10 in the front direction. The sub unit board 12 is attached to the standing main board 10 via connectors 10d and 12g so as to be substantially perpendicular to the board surface of the main board 10. The slot board 14 is mounted via the connectors 12h, 12i, 14a, and 14b so as to be substantially flush with the subunit board 12. Since the connector 12h and the connector 14a and the connector 12i and the connector 14b are connected to each other, the distance between the connector 12h and the connector 12i is set to be equal to the distance between the connector 14a and the connector 14b.

  Of course, this is only an example of mounting, and as shown in FIGS. 8 and 9, for example, the main board 10, the subunit board 12, and the slot board 14 are mounted to each other with connectors so that they are substantially in the same plane. May be. 8 is a perspective view, and FIG. 9 is a plan view. However, in order to connect the plurality of subunit boards 12 to the main board 10, the main board 10 is erected as shown in FIG. 6, and the plurality of subunit boards 12 are parallel to each other with respect to the main board 10. In addition, it is desirable that the connection is made substantially perpendicular to the substrate surface of the main board 10.

  Thus, in this embodiment, the main board 10, the subunit board 12 and the slot board 14 are provided, and only the slot board 14 is replaced or only the slot board 14 and the subunit board 12 are replaced. Can be used as they are, so that it is possible to quickly and inexpensively replace the copy destination recording medium at the time of abnormality or failure of the slot 14c.

  In this embodiment, the slot board 14 and the subunit board 12 are exchanged when exchanging the type of recording medium at the copy destination, but at the time of exchanging the type of recording medium as in the case of a slot abnormality or failure. Alternatively, it is possible to adopt a configuration in which only the slot board 14 is replaced.

  10 and 11 show the configuration in this case. The main board 10 and the subunit board 12 are integrated. The integrated board 13 includes a USB signal processing circuit and connectors 12h and 12i, and an SD memory signal processing circuit and connector 20. Assuming that the connectors on both the left and right sides are USB memory connectors 12h and 12i and the center connector is an SD memory connector 20, if the copy destination recording medium is a USB memory, as shown in the perspective view of FIG. The connectors 14a and 14b of the slot board 14 having the USB memory slot 14c are attached to the left and right connectors 12h and 12i of the integrated board 13, respectively.

  On the other hand, when the copy destination recording medium is an SD memory, the connector 22 of the slot board 14 having the slot 14c for the SD memory is connected to the connector 20 at the center of the integrated board 13 as shown in the perspective view of FIG. Attach to. As a result, not only an abnormality or failure of the slot 14c but also a change in the type of the recording medium can be handled by replacing only the slot board 14 while using the integrated board 13 as it is.

  Further, the main board 10 and the subunit board 12 are not integrated to form the board 13, but the configuration in which the main board 10 and the subunit board 12 are functionally separated as shown in FIG. 1 is maintained. However, the subunit board 12 may be provided with a USB signal processing circuit and connectors 12h and 12i and an SD memory signal processing circuit and connector 20. A conversion circuit and connectors 12h, 12i, and 20 may be provided. 12 and 13 show the configuration in this case. The sub unit board 12 includes a signal processing circuit and connectors 12h and 12i for USB and a signal processing circuit and connector 20 for SD memory. If the connectors at the left and right ends are USB memory connectors 12h and 12i and the center connector is an SD memory connector 20, when the copy destination recording medium is a USB memory, as shown in the perspective view of FIG. The connectors 14a and 14b of the slot board 14 having the USB memory slot 14c are attached to the left and right connectors 12h and 12i of the subunit board 12, respectively.

  On the other hand, when the copy destination recording medium is an SD memory, as shown in the perspective view of FIG. 13, the connector 22 of the slot board 14 having the slot 14c for the SD memory is connected to the connector 20 at the center of the subunit board 12. Attach to. When the conversion circuit is configured on the subunit board 12, it can easily be applied to recording media other than the USB memory and the SD memory.

  Further, in this embodiment, the slot 16 (see FIG. 2) for mounting the copy source recording medium is not particularly mentioned, but the slot 16 is also connected to the integrated board in the same manner as the slot 14c. It is good also as a structure mounted in the detachable slot board via a connector. As described above, the copy source recording medium and the copy destination recording medium are preferably of the same type. However, when both the copy source and the copy destination are changed from the USB memory to the SD memory, the slot in which the slot 16 is mounted. This can be dealt with by simply changing the board from the USB memory to the SD memory and changing the slot board 14 from the USB memory to the SD memory.

  Note that the abnormality or failure of the recording medium and the abnormality or failure of the slot 14c in which the recording medium is mounted may be identified as follows. That is, it is assumed that after data is copied to a plurality of recording media, the LED is lit red in a specific slot 14c, and copying is not normally completed. In this case, next, the recording medium is mounted in another slot 14c and copying is performed again. If the slot 14c in which the recording medium is mounted again lights in red and copying is not normally completed, it can be determined that there is a high possibility that there is an abnormality or failure in the recording medium, not the slot 14c. On the other hand, if the copying is normally completed by replacing the slot 14c, it is determined that there is a high possibility that the original slot 14c has an abnormality or a failure, and the slot board 14c may be replaced.

In the above embodiment, the USB memory and the SD memory are exemplified as the recording medium, but it goes without saying that the present invention can also be applied to other arbitrary recording media.
