Issues a move command that functions as an instruction. When a normal reception response is obtained from the director side for the move command, the host computer transfers a data byte (command parameter) as medium transport information.

This data byte includes the source address and destination address of the cartridge, and is stored in the queuing table of the accessor controller 228. The accessor controller 228 includes the accessor unit 7

A CE panel 96 having a display unit 298 and a floppy disk select switch 2100 and a floppy disk device 2104 are connected to the interface control unit 2.
It is connected to the CPU 270 via 94 and 2102. FIG. 46 is a diagram illustrating an example of a hardware configuration of a machine controller. In FIG. 46, CPU 400
Is the program storage area 4 via the common bus 401
24 and a work area 426 are connected to the RAM 416 and the nonvolatile memory 420. RAM 416 is
Through a bus switching circuit 418, they are commonly connected to an accessor controller 228. In the program storage area of the RAM 416, an operation control program is installed from the floppy disk device 2104 of the accessor controller 228 via the bus switching circuit 418. The accessor controller 228 connects a signal line for outputting a bus switching signal to the bus switching circuit 418 and a signal line for outputting data and address to the bus switching circuit 418.

The CPU 400 includes an interface unit 422
Through the interface section 156 of the drum control section. CPU 400 communicates information with CPU 150 via these interface units 422 and 156. The interface unit 422 is connected to the port 290-1 of the machine controller interface control unit 288 of the accessor controller 228.

The CPU 400 receives the detection output of the reflection type photoelectric sensor 362 provided at the tip of the hand assembly 16. The CPU 400 is connected to drive circuits 402, 406, and 414 for driving the X-axis motor 42, the Y-axis motor 46, and the θ rotation motor 25 of the accessor 14. CPU 400 has a hard counter 410 for counting the output of encoder 404 attached to X-axis motor 42 and a hard counter 412 for counting the output of encoder 408 attached to Y-axis motor 46.
Hard counter 4 that can read and reset the value of
10, 412.

Next, the operation of correcting the position of the accessor 14 as a carriage will be described. FIG. 47 shows the accessor 14
FIG. 4 is a diagram for explaining a sensor provided in the apparatus. FIG.
(A) shows a sensor 362 mounted on the hand assembly 16 and a sensor 365 mounted on the rail base 32 for detecting a position along the X direction. FIG.
(B) shows a sensor 367 for detecting the position of the base 27 with respect to the base 24 of the hand assembly 16.

The positioning of the accessor 14 in the X-axis direction is as follows.
Origin flag 365 provided in accessor unit 9
Is performed on the basis of The origin flag 365 is detected by the sensor 363. However, the distance between the attachment position of the sensor 363 on the rail base 32 and the center position of the hand of the hand assembly 330 may not be assembled as specified. Therefore,
Even if the X-axis motor 42 is driven based on the output of the sensor 363, the gripping center position of the hand may be shifted in the X direction. The hand assembly 16 reciprocates along the vertical column 18 in the Y-axis direction. However, the vertical column 18 is
The column 18
In addition to the displacement in the Y direction between the lower position and the upper position, the displacement in the X direction occurs. Further, if the sensor 367 and the detection position of the sensor flag 341 are mounted so as to be shifted from each other in the rotation direction, the hand unit 33
0 grips the cartridge diagonally. If such a displacement occurs, not only can the cartridge contained in the cell not be accurately grasped, but also it becomes impossible to push the cartridge into the cell or the accessor mount cell. Therefore, in the case of using the accessor 14 which does not perform such displacement correction, the cell pitch cannot be reduced, and it becomes difficult to increase the capacity of the cartridge in the library device.

FIGS. 48 to 51 are operation flowcharts for explaining the position correcting operation of the accessor serving as the carriage. This operation flowchart will be described together with the position correction operation explanatory diagram of the accessor shown in FIGS. 52 to 53.

(1) Steps S101 to S102: CP
U400 moves the X-axis, the Y-axis, and the Z-axis to the respective home positions in step S101. That is, the CPU 400
The X-axis motor 42 is driven via the motor drive circuit 402 to position the photoelectric sensor 363 at a position where the edge of the origin flag 365 is detected. Further, the CPU 400 drives the Y-axis motor 46 via the motor drive circuit 406, and moves the hand assembly 16 to a height at which the photoelectric sensor 362 can detect the position correction flags 910 and 920. Then, the CPU 400 rotates the motor 25 so that the photoelectric sensor 367 is located at the detection position where the origin position of the sensor flag 341 is detected. The origin position of the sensor flag 341 is determined by the sensor 362 and the position correction flag 910 or 9.
20 is assembled at a position different from the position directly opposite to 20.
Then, the base 28 of the hand assembly 16 is
7, the tilt angle of the hand assembly is-
It is set to 12 degrees. Then, in step S102, the CPU 400 clears the contents of the carriage position correction table. Also, the hard counters 410, 412, 41
The value of 3 is reset.

(2) Steps S104 to S106: CP
U400 sets the sensor 362 to the position correction flag 910.
First, the motor 25 is driven to face (flag A). Then, the sensor 362 sets the position correction flag 91
The base 27 is positioned at an angle assumed to face 0. Further, the CPU 400 drives the X-axis motor 42. That is, the CPU 400 drives the X-axis motor 42 by the standard value XNA. This standard value is the origin flag 3
Given as a distance from 65. And the sensor 36
X which is assumed to face the position correction flag 910
The rail base 32 is positioned at the position in the direction. In this state, the CPU 400 drives only the motor 42 to reciprocate. The optical axis of the sensor 362 is the position detection flag 91.
Reciprocating scanning is performed on the zero along the X direction. This sensor 36
When the detection output of the sensor 362 is turned on during the reciprocal scanning of the optical axis No. 2, the CPU 400
Read the value of 10. Then, CPU 400 stores this value in work area 426 of memory 416. CP
The values stored in work area 426 by U400 are shown in FIG.
The measured value XAA shown in FIG.

(3) Steps S108 to S110: CP
U400 sets the sensor 362 to the position correction flag 920.
The motor 25 is driven to face (flag B). Then, the base 27 is positioned at an angle at which the sensor 362 is assumed to face the position correction flag 920. Next, in this state, the CPU 400
Only the reciprocating drive is performed. The optical axis of the sensor 362 is reciprocally scanned on the position detection flag 910 along the X direction.
During the reciprocal scanning of the optical axis of the sensor 362, the sensor 362
When the detection output is turned on, the CPU 400 reads the value of the hard counter 410. And CPU4
00 stores this value in the work area 426 of the memory 416. The value stored in the work area 426 by the CPU 400 is the measured value XNB shown in FIG.

(4) Steps S112 to S116: CP
U400 is an average value XH of the measured value XNA and the measured value XNB.
Ask for. Next, a difference value between the standard value XNA and the average value XH is obtained. This difference value is added to the standard value XNA. This addition result is set as a new X target value. CP
U400 drives the X-axis motor 42 to position it at the new X target value. Thus, the position correction value in the X direction is obtained, and the position correction value in the X direction
Are stored in the correction value table.

(5) Steps S118 to S122: CP
U400 drives motor 25 so that sensor 362 faces position correction flag 910. Sensor 362
The base 27 is positioned at an angle that is assumed to face the position correction flag 910. That is, the CPU 40
A value of 0 drives the motor 25 by the standard value ZNA. The standard value ZNA is given by the rotation angle after the sensor 367 detects the sensor flag 341. After this, CPU4
00 drives only the motor 25 to reciprocate. The optical axis of the sensor 362 reciprocally scans the position detection flag 910 in the X direction. During the reciprocal scanning of the optical axis of the sensor 362,
When the detection output of the sensor 362 is turned on, the CPU
400 reads the value of the hard counter 413. Then, the CPU 400 stores the measured value ZAA in the memory 416.
Is stored in the work area 426. Further, the CPU 400
Calculates a difference value between the standard value ZNA and the actually measured value ZAA,
It is stored in the work area 426 as the correction value ZHA.
Thus, the correction value of the Z position on the surface on which the position correction flag 910 is provided is obtained. The first correction value in the Z direction is stored in a correction value table in the work area.

(6) Steps S124 to S126: CP
U400 drives motor 25 so that sensor 362 faces position correction flag 920. Sensor 362
Is positioned at an angle which is assumed to face the position correction flag 920. That is, the CPU 40
A value of 0 drives the motor 25 by the standard value ZNB. Thereafter, the CPU 400 drives only the motor 25 to reciprocate. The optical axis of the sensor 362 reciprocally scans the position detection flag 920 in the X direction. During the reciprocal scanning of the optical axis of the sensor 362, when the detection output of the sensor 362 is turned on, the CPU 400 reads the value of the hard counter 413. Then, CPU 400 stores this measured value ZAB in work area 426 of memory 416. Furthermore,
The CPU 400 calculates a difference value between the standard value ZNB and the actually measured value ZAB, and sets the difference value as the correction value ZHB in the work area 426.
To be stored. Thus, the position correction flag 910
The correction value of the Z position on the surface where is provided is obtained.
The second correction value in the Z direction is stored in a correction value table in the work area.

(7) Step S128: CPU 400
Calculates the new target value by adding the correction value ZHA to the standard value ZNA. Then, CPU 400 positions sensor 362 at position correction flag 910 based on the new target value. (8) Steps S130 to S136: Next, the CPU 40
A value of 0 determines the correction value of the detection sensitivity of the sensor 362 in the X and Y directions when the tilt angle of the hand assembly 16 is -12 degrees. Further, the CPU 400 obtains a correction value of the detection sensitivity of the sensor 362 in the Y direction when the inclination angle of the hand assembly 16 is -5.5 degrees. A method for obtaining these detection sensitivity corrections will be described later. The sensor 362 is
When the hand assembly 16 faces the position correction flag 910 at an inclination angle of −12 degrees, the optical axis of the sensor 362 coincides with the horizontal plane. Therefore, when the inclination angle of the hand assembly is -5.5 degrees, the optical axis of the sensor 362 is shifted from the horizontal plane, and thus the detection sensitivity needs to be corrected.

(9) Step S138: CPU 400
Calculates the new target value by adding the correction value ZHB to the standard value ZNB. Then, CPU 400 positions sensor 362 at position correction flag 920 based on the new target value. (10) Steps S140 to S150: Next, the CPU 4
00 returns the tilt angle of the hand assembly 16 to the state of −12 degrees. Then, the CPU 400 obtains a correction value of the detection sensitivity of the sensor 362 in the X direction and the Y direction. Further, C
PU 400 sets the inclination angle of the hand assembly 16 to −
Set to 5.5 degrees. Then, the CPU 400 obtains a correction value of the detection sensitivity of the sensor 362 in the Y direction at the inclination angle. A method for obtaining these detection sensitivity corrections will be described later. After determining the correction value of the detection sensitivity, the CPU 4
00 returns the tilt angle to the state of -12 degrees.

(11) Steps S152 to S158: Next, the CPU 400 detects the inclination angle of the vertical column 18 and obtains a correction value thereof. First, the CPU 400
Positions the sensor 362 at a position facing the position correction flag 910. Next, the CPU 400 sets the sensor 36
2 is positioned on the position correction flag 930. And C
The PU 400 reciprocally scans the position correction flag 930 along the X direction with the sensor 362 while holding the Y position. During the reciprocal scanning of the optical axis of the sensor 362, the sensor 3
At the time point when the detection output of 62 is turned on, the CPU 400
Reads the value of the hard counter 410. And C
The PU 400 obtains the difference between the expected value of the position correction flag 930 in the X direction position and the measured value, and recognizes the difference as the positional deviation difference between the upper position and the lower position of the Y position. This difference value is stored in the correction value table in the work area 426.

(12) Step S120: CPU 400
Stores the values stored in the correction value table in the nonvolatile memory 420
And the position measurement processing operation ends. Next, the sensor sensitivity correction operation will be described. FIG.
9 is a diagram showing the relationship between the position correction flags 910, 920, 930 and the sensor 362. FIG. 56 is an explanatory diagram of the sensor sensitivity correction operation.

This target position is set within the area of the black portion 952c. Then, the CPU 400 moves the sensor 362 to the target position.

(4) Steps S216 to S226: CP
U400 moves sensor 362 in the scanning direction in the Y direction (see FIG. 56) while holding the Y position. And
It is determined whether or not the output of the sensor 362 has been turned on.

CPU 400 positions sensor 362 at this target position.

(2) Steps S238 to S246: CP

FIG. 66 is a diagram for explaining the coordinate system of the reference cells of the drum unit on which the DEE magazine is mounted. In FIG. 66, the coordinate system of the reference cell will be described by taking one of the seven segments of the magazine drum 175 in the drum unit 169 as an example.
The drum unit 169 stores the magazine 20 in each of the magazine mounting shelves 184a to 184d of the magazine drum 175.

so. The lower right end 17 of the drum unit 169
0a is used as a reference point for coupling with another unit. Then, the reference cell 254m of the drum unit 169
Are expressed in an orthogonal coordinate system having the frame reference origin Fso as the origin. The coordinate value of the reference cell 254m is represented by the coordinate value (Xs, Ys) of the center position of the reference cell 254m. Reference cell 25 of each magazine 200s to 200v
The coordinate value (Xs, Ys) at the center position of 4 m is represented by a coordinate value in an orthogonal coordinate system having the frame reference origin Fso as the origin. As described above, the magazines 200s to 200v are:
Guide plates 186a, 187a, 188a, 189

To 214d and the positioning hole 201 of the magazine 200
a, 201b, the drum unit 169 is positioned substantially accurately with respect to the reference point 169a.

Therefore, the reference cell 254 of the magazine 200
The coordinate value (Xs, Ys) of the center point of the actual position of m is a coordinate value based on the frame reference origin Fso, which is the positioning reference point 169a. FIG. 67 is a diagram showing the relationship between the actual position center of the reference cell and the standard position center. In FIG. 67, the coordinate value (X

Is a position separated from the coordinate value (Xm, Ym) by a distance Lx in the X direction and a distance Ly in the Y direction. These dimensions Lx,
Ly is stored in a part of the cell address map 432 described above. That is, the position correction mark 190a is
Since it is accurately attached to the frame 180, the coordinate value (Xm, Y
m) is a coordinate value based on the frame reference origin Fso. The actual position center point Pp of the reference cell 254m is the reference cell 254 when the reference origin Fso of the frame is set as the origin.
m is offset from the standard position center point Ph in the X direction and the Y direction, respectively. The coordinates of the standard position center point Ph of the reference cell 254m are represented by coordinate values (Xh, Yh). The standard position center point Ph of the reference cell 254m is a point where the center point of the reference cell 254m in the standard orthogonal coordinate system having the position flag 365 of the accessor unit 9 as an origin should exist. The library device 2 includes a plurality of units 7,
9, 9, 10a and 10b are combined and assembled, so that an offset is generated between the actual position center point Pp of the reference cell 254m and the standard position center point Ph. The value of this offset is measured using the position correction mark 190a.

FIG. 69 is a block diagram of the machine controller 232-1.
3 is a flowchart for explaining the operation of FIG. In the figure, first, C
After the power is turned on, the PU 400 performs an initialization operation in step S200. During this initialization operation, the CPU 400
Are connected to the motor 4 via the drive circuits 402, 406, and 412.
2, 46 and 25 are driven to position the accessor 14 at the reference position set in the accessor unit 7. C
The PU 400 drives each of the motors 42, 46, and 25 of the accessor 14 to a position where the sensor 363 detects the position flag 365 and the sensor 362 of the hand assembly 16 detects the position flag 365.

Next, the CPU 400 proceeds to step S21.
At 0, it is checked whether or not a position correction value is stored in the X position and Y position correction value table 448 in the nonvolatile memory 420. If the position correction value has not been stored, the CPU 400 proceeds to step S220 for executing the operation of measuring the position correction value. Upon completion of the processing in step S220, the CPU 400 proceeds to step S212.

On the other hand, if the position correction value has been stored, the CPU 400 shifts to step S212 to confirm the presence or absence of an operation command. The CPU 400 determines in step S
If an operation command is received at 212 through the interface unit 422, the process proceeds to step 214. CP
U400 determines in step S214 whether the type of the operation command is a magazine presence / absence check operation instruction command. If the command is a magazine presence check operation instruction command, the CPU 400 moves to step S216 and executes a magazine presence check operation. If another command is received in step S214, the CPU 400 executes the processing of that command in step S218. After the completion of processing of the magazine presence / absence check operation command or other commands, the process returns to step S212.

FIG. 70 to FIG. 72 are flowcharts showing the operation of measuring the position correction value. Steps S240 to S244: In step S240, the CPU 400 loads the address (frame number and surface number) of the unit of the drum unit 169 to be measured for the position correction value into the designated address table 436. Assuming that the drum unit 169 is the drum unit 10b shown in FIG. 62, the address of the drum unit 169 has a frame number of Frame = 2.
Then, the surface number becomes Z = 0. Next, in step S242, the CPU 400 takes in the address of the reference cell 254m. As the address of the reference cell 254m, the coordinate value of the cell in the drum unit shown in FIG. 63 is set.
The reference cell 254m is at the lower right of each of the magazines 200s to 200v. X of reference cell 254m of magazine 200s
The address is “04” and its Y address is “0”.
4 ".

The X addresses of the magazines 200t to 200v are the same as the X address of the reference cell 254m of the magazine 200s, and are all "04". On the other hand, the Y address of the magazine 200t is “0D”, the Y address of the magazine 200u is “16”, and the
The Y address of 00v is “1F”. These X address and Y address are represented by hexadecimal numbers.

Then, in step S244, CPU 400 sets relative position flag pointer RPF to “N =
1 ". The value of the pointer RPF is
0t to 200v are specified in order. Steps S246 to S252: Next, the CPU 400
Refers to the cell address map 432 based on the X address “04” of the reference cell 254m of the magazine 200s specified by the pointer RPF. The CPU 400 calculates the reference cell from the sum of the X coordinate value (Xs) from the frame reference origin Fso, the width of the drum unit, and the dimensional difference in the X direction from the position of the origin position flag 365 to the reference point 169a of the drum unit. Standard position center P of 254m
Obtain the X coordinate value Xh of h. And the CPU 400
Converts the X coordinate value Xh into an encoder (tachometer) 40
It is converted into a count number of 4 and stored in an internal register.
Further, the CPU 400 reads from the cell address map 432 a dimension Lx corresponding to a difference value between the X coordinate value of the expected point Pe and the X coordinate value of the standard position center point Ph, and S, the X coordinate value Xh
Subtract from Further, the CPU 400 includes the hand unit 3
The difference value in the X direction between the center line of 30 and the optical axis of the sensor 362 is subtracted from the X coordinate value Xh. X between the hand center line of the hand unit 330 and the optical axis of the sensor 362
The difference value in the direction is stored in the cell address map 432 described above. The CPU 400 calculates the calculation result as the expected point P
It is stored in the expected value table 440 as the X coordinate value of e.

Steps S254 to S260: Next,
The CPU 400 refers to the cell address map 432 based on the Y address “04” of the reference cell 254m of the magazine 200s specified by the pointer RPF. CPU
400 is a Y coordinate value (Y
s) and the dimensional difference in the Y direction from the position of the origin position flag 365 to the reference point 169a of the drum unit,
The Y coordinate value Yh of the standard position center Ph of the reference cell 254m is obtained. Then, the CPU 400 determines that the Y coordinate value Yh
Is converted into the count number of the encoder (tachometer) 408 and stored in the internal register. Further, the CPU 400
Reads the cell address map 432 for a dimension Ly corresponding to the difference between the Y coordinate value of the expected point Pe and the Y coordinate value of the standard position center point Ph, and subtracts it from the Y coordinate value Yh. Further C
The PU 400 subtracts a difference value in the Y direction between the center line of the hand unit 330 and the optical axis of the sensor 362 from the Y coordinate value Yh. The difference value in the Y direction between the hand center line of the hand unit 330 and the optical axis of the sensor 362 is stored in the cell address map 432 described above. CPU
400 stores the calculation result in the expected value table 440 as the Y coordinate value of the expected point Pe.

Steps S262 to S268: CPU
400 is for adding the difference value in the X direction between the measurement start point Pi and the expected point Pe stored in the cell position standard value table 434 to the X expected value stored in the expected value table 440 to position the sensor 362. The X coordinate of the target value is calculated. Next, the CPU 400 adds the difference value in the Y direction between the measurement start point Pi and the expected point Pe stored in the cell position standard value table 434 to the Y expected value stored in the expected value table 440, and the sensor 362 is added. Calculate the Y coordinate of the target value for positioning. The Z target value is a rotation angle of the motor 25 for positioning the hand assembly 16 at a position facing the cell. This value is obtained from the Z address (Z = 1 or 0) stored in the designated address table 436.
The CPU 400 calculates. The CPU 400 positions the accessor 14, which is a carriage for transferring the sensor 362 to the target position stored in the target value table 438. That is, the CPU 400 drives the motors 42, 46, and 25 to position the sensor 362 at the measurement start point Pi.
The CPU 400 resets the contents of the hard counters 410 and 412 before the movement of the sensor 362 starts.

Steps S268 to S276: After the sensor 362 is positioned at the measurement start point Pi, the CPU 4
00 drives only the motor 42 in order to move the rail base 32 along the X rail 20 with the driving of the motor 46 and the motor 25 stopped. That is, the sensor 362 is moved from the measurement start point Pi to the white portion 454 of the position measurement mark 190a along the X measurement direction. Then, the CPU 400 detects a point in time when the detection output of the sensor 362 is turned on while the sensor 362 is moving. The point in time when the sensor 362 reaches the white portion 454 is detected. The CPU 400 reads the value of the hard counter 410 that counts the output of the encoder 404 when the output of the sensor 362 is turned on. The value of the hard counter 410 is an X actual measurement value (Xm). X
The measured value Xm is stored in the position storage value table 444 as an X position storage value. During the position measurement operation, CP
U400 updates and holds the current position of sensor 362 in current value table 442 based on hardware counters 410 and 412. After the output of the sensor 362 is turned on, the CPU 400 stops driving the motor 42. Next, CPU 400 obtains a difference between the expected X value of expected value table 440 and the measured X value stored in stored position value table 444. This difference value is stored in the correction value table 446 as an X correction value. CPU400
Drives the motor 42 in the reverse direction and sets the sensor 362 to X
It is positioned at the position of the measured value Xm, and it is confirmed that there is reflection from the white portion 454.

Steps S280 to S292: CPU
400 positions the sensor 362 at the measurement start point Pi. After the sensor 362 is positioned at the measurement start point Pi, the CPU 400 drives only the motor 46 to move the base 27 along the rail guide 22 with the driving of the motor 42 and the motor 25 stopped. That is, when the sensor 362 moves along the Y measurement direction, the measurement start point P
It is moved from i toward the white portion 452 of the position measurement mark 190a.

Then, the CPU 400 detects a point when the detection output of the sensor 362 is turned on while the sensor 362 is moving. The point in time when the sensor 362 reaches the white portion 452 is detected. CPU 400 reads the value of hard counter 412 that counts the output of encoder 408 when the detection output of sensor 362 is turned on. The value of the hard counter 412 is a measured Y value (Ym). The measured Y value Ym is stored in the position storage value table 444 as a Y position storage value. After the output of the sensor 362 is turned on, the CPU 400 stops driving the motor 46.

Next, CPU 400 obtains the difference between the expected Y value of expected value table 440 and the measured Y value stored in stored position value table 444. This difference value is stored in the correction value table 446 as a Y correction value. CPU
400 drives the motor 46 in the reverse direction,
2 is positioned at the position of the Y actual measurement value Ym, and it is confirmed that there is reflection from the white portion 452.

Steps S296-S300: CPU
400 determines whether the value of the relative position flag pointer RPF is the maximum value after the process of step S292 is completed. That is, the CPU 400 determines whether or not the position measurement processing for the position correction mark 190d of the magazine 200v has been completed. Magazine drum 1 of drum unit 169
75, the number of mounting shelves 184a to 184d is
There are four. Therefore, the CPU 400 sets the pointer RPF
Is determined to be “N = 4”. If the value of the pointer RPF is not the maximum value, 1 is added to the value of the pointer RPF. Then, the CPU 400 proceeds to step S
Returning to 246, the position measurement operation for the next position correction mark is executed.

If the value of the pointer RPF matches the maximum value, the correction value for each of the position correction marks 190a to 190d stored in the correction value table 446 is changed to the X position / Y in the nonvolatile memory. It is stored in the position correction table 448. The CPU 400 ends the position measurement operation, and
It returns to the operation command reception waiting state of step S212 shown in FIG.

Although the position measuring operation is performed on the drum unit having the DEE magazine, it may be performed on the drum unit having no DEE door shown in FIGS. In this case, the position measurement mark 190a is arranged on the pillar 686a or the base 654a of the drum unit 650a. As described above, since the position measurement operation between the accessor unit 9 and the drum unit 10 is executed, the library device 2 can absorb an assembly error generated when the units are connected to each other. Therefore, the assembling accuracy of the library device 2 can be reduced, and the assembling time can be reduced.

In the present embodiment, only the example of the I3480 magnetic tape cartridge has been described as the cartridge for accommodating the storage medium, but the present invention is not limited to this. The present invention can be applied to a library apparatus having cells for storing other types of magnetic tape cartridges and optical disk cartridges.

In this embodiment, the accessor is an XY moving mechanism, but various modifications are possible. For example, the accessor may be a Y-θ moving mechanism. In this case, the accessor as the Y-θ moving mechanism is disposed inside the cylindrical cell drum.

[0190]

According to the present invention, the manufacturing time of the library device can be reduced. Also, the assembly time at the installation location of the library device can be reduced. Since the cell pitch can be reduced, a large number of cartridges can be accommodated.

Since the upper unit having the rotating drum can be attached, the capacity of the cartridge can be further increased. The reliability of the library device can be improved. Various combinations of cells can be created by combining the cell units of the cartridge storage shelf.

A system in which only drive units are already installed can easily be changed to a library device.
