Description

DETAILED DESCRIPTION OF THE INVENTION [Utilization in Business] The present invention relates to a disk file device, and more particularly to a disk file device equipped with a stocker for storing a large number of cartridges.

[Conventional technology]

5 and 6 show a conventional disk file device disclosed in, for example, Japanese Utility Model Application No. 61-170157. In FIG. 5, a cartridge (1) containing a disk serving as an information recording medium is shown. , stocker (2) K are stacked on a shelf and arranged in a horizontal direction. The recording and reproducing device (3) reads and writes information on the disc in the cartridge (1). The insertion/removal mechanism (4) is rotatably provided by a rotation mechanism attached to a horizontal movement table (5) provided on a carriage (6) that moves up and down, and
2) or recording/reproducing device ft (cartridge (1) in 31)
This is a mechanism for inserting and withdrawing. Rail (7
) are in the shape of round rods, and the left and right sides are provided in parallel, and are slidably fitted into the slider (8) attached to the carriage (6) to guide the elevation and descent of the carriage (6). The belt (9) is connected to the carriage (6) and the balancer (11) and transmits the power of the lifting motor (10).

The specific configuration of the stocker (2) will be explained with reference to FIG. The stocker (2) consists of a horizontally long box (91) with an opening (90) on the side, and a cartridge (91) inside.
1) has side plates (92
a1. (A groove (93) with a width approximately corresponding to the thickness of the cartridge (1) is formed in 92b'j.
3), the central part has a width that approximately corresponds to the thickness of the cartridge (1), and a tapered surface (94) is formed on the opening (90) side so that the width dimension is I118,
The plurality of partition walls (95) that partition these grooves (93) are also spaced so that the interval on the opening (90) side is 1@order.
Tapered surfaces (96) are formed on both sides thereof. In this way, the vertical and horizontal dimensions of the opening (90'M) of the groove (93) are formed so that they gradually become larger from the center, so that the cartridge insertion/removal mechanism (4) can be attached to the stocker (2). When inserting or removing the cartridge (1), even if the cartridge (1) is displaced with respect to the groove (93), both tapered surfaces (94), (96') K
Therefore, the amount of displacement can be absorbed and the operation can be performed smoothly.

d, near the innermost part of the box (91) of the bulkhead (95).
The retaining spring (87), which is bent into a letter shape, is the partition wall (95).
It is locked. This holding spring (87) is attached to the stocker (
2) The front and back surfaces of the cartridge (X) housed inside are elastically clamped from both sides by the expanding action of the spring to restrict movement in the front and back direction.

With the above configuration, the cartridge (1) stored in the stocker (2) can be selectively taken out and pushed into the recording/reproducing device #(3), or vice versa.
) is returned to its original position. - For example, when supplying the cartridge (1a) shown in Figure @5 to the recording/reproducing device (3a'), first remove the cartridge (1a) and insert it into the recording/reproducing device. A command is given to this device to insert it into (3a).

Then, the controller built into this device (not shown)
Therefore, the motor (10) that raises and lowers the carriage (6)
) and the horizontal moving table (5) in the horizontal direction to move the stocker (2)
Move the insertion/removal mechanism (4) until it faces and aligns with the cartridge (1a) inside. A gripping mechanism (not shown) provided in the insertion/removal mechanism (4) grips the cartridge (1a) and pulls it into the insertion/removal mechanism (4). When this retraction is completed, the lifting motor (1o) and the lateral movement motor (not shown) are driven, and the insertion port (3b) of the recording/reproducing device (3a) is driven.
Move the insertion/removal mechanism (4) until the end. Next, the sword trille (1a) is inserted into the recording/reproducing device (3a). The inserted cartridge (1a) is further pulled into the recording/reproducing device (3a) by a retracting means (not shown) provided in the recording/reproducing device (3a) to a position where information can be recorded and reproduced. . When recording and reproduction are completed, the cartridge (la) is returned to its original position in the stocker (2). In that case, the operation is the opposite of the operation described above.

[Details to be Solved by the Invention 1 #'i1 Since the conventional disk file device is configured as described above, the retaining blade attached to the innermost part of the stocker only holds the front and back surfaces of the cartridge. Therefore, the cartridge is likely to be misaligned, and there is a risk that the cartridge may pop out toward the opening side of the stocker due to vibration or the like. Furthermore, if the clamping force of the retaining spring is increased to eliminate positional displacement, there is a problem in that it is necessary to increase the main force of the motor for inserting and removing the cartridge.

This invention was made to solve the above-mentioned problem, and it is an object of the present invention to provide a disk file device in which the position of the cartridge does not easily shift after the cartridge is stored in a stocker, and the cartridge does not easily move due to vibration or the like. [Means for solving the problem] The belt is tensioned, and this belt is driven by a drive motor in the vertical direction of the carriage of the cartridge, and a part of the belt is cut and connected to a U-shaped connecting fitting. The connecting portion and the cartridge gripping opening of the insertion/removal mechanism are at the same height.

- Because the belt is stretched close to the front end of the belt, when the cartridge in the stocker tries to jump out of the stocker due to vibration, impact, etc., the front end of the cartridge comes into contact with the belt, causing the belt to come into contact with the belt. Most cartridges do not pop out. Furthermore, since the connecting fitting is U-shaped, the clamper does not come into contact with the connecting fitting when the insertion/removal mechanism grips the cartridge.

〔Example〕

FIGS. 1 to 4 show an embodiment of the present invention, and in the figures, a recording/reproducing device (3) is attached to a pedestal (54) on the top surface of a base (55). Further, the stocker (2) is attached to the upper part of the pedestal (54).

Note that the upper part of the stocker (2) has a supply/discharge device fl (s6) that takes in the cartridge (13) from the outside of the main snow storage, but its 7 details are omitted.Insertion and removal of the cartridge (1) The mechanism (4) is mainly composed of a rotatable C-frame shaped holder (28).The holder (2B) consists of a supporting member (28c) for reversing and a pair of C-frames. members (28a) and (28b), the open end of which faces the cartridge (1), and the closed end of which faces the lateral movement table (5).

The cut end of the restraining belt (71') is fastened by the U-shaped connecting fitting (75) and the fastening fitting (76). Further, the vertical length of the concave portion of the U-shaped connecting fitting (75) is slightly larger than the thickness of the cartridge (1).

The stocker (2) and the playback device f (31 are each provided in two rows, this is to record and play back more information faster. Therefore, the insertion/removal mechanism (4) needs to be moved laterally. The lateral movement motor (13) is attached directly to one end of the carriage (6), and is rotatably attached to the pulley (18) attached to the end of the motor shaft and the other end of the carriage (6). A lateral movement table (5) is connected to a belt (19) connected to a pulley (63) and rotated, and the lateral movement table (5) is moved laterally.The lateral movement table (5)
A main shaft (not shown) and a gear (26) necessary for reversing the insertion/removal mechanism (4) are fixed to the central part of.

The main shaft is connected to the closed end member (28G) forming a C frame-shaped holder (2B) via a cross roller bearing.
) is reversibly supported. Further, a motor (23) necessary for reversing is attached to the member (28c), and a pinion (23) that meshes with the gear [26] is attached to the shaft end of the motor (23).
25) is installed. Therefore, the motor (23
) will revolve around the gear (26) while rotating.

Next, a method of moving the gripping mechanism will be explained.

The gripping mechanism consists of a moving body (29) K, a C frame-shaped holder (28), and a motor (31) directly attached to the closed end side of a thin plate member (28a) forming the holder (2B). , a pulley (
60) and a boot IJ (61) K which is rotatably attached to the open end of the thin plate member (28a) (a bell which is connected and rotates)

Move it back and forth. In addition, a slider (51) is sloped on the support base (63) as shown in FIG.
The slider (51) is a member (28b) of the holding body (28).
It moves along the rail (50) attached to the. A sensor (1) attached to the moving body (29) detects the front side of the cartridge (1).

A sensor (65) provided at the rear of the stocker (2) detects the rear surface of the cartridge (1). Retention spring (87)
are provided on both sides of each column of the stocker (2) to stably hold the cartridge (1) within the stocker (2). Regarding the gripping mechanism, (44) is a swing motor, a link is connected to the motor shaft, and the link is connected to the clamper (
40), and opens and closes the clamper (40) by the swing of the swing motor (i4). The width of the U-shaped connecting fitting (75) is smaller than the gap between the cartridges (1) attached to the left and right stockers (2), and the convex part is placed on the stocker side within this gap. . Further, the width of the restraining bell (71') is larger than the above-mentioned gap, and is stretched with a slight gap from the front end of the cartridge (1) stored in the stocker (2)K.

Next, the operation will be explained. - As an example, in order to take out the cartridge (1a '>' shown in cause 4 and insert it into the recording/playback device 1 (3a), first take out the cartridge (1a) and insert it into the playback mount (3a). A command is input to this device.The controller built into this device (not shown) drives the lifting motor (10) and the lateral movement motor (13), and the cartridge gripping opening of the insertion/removal mechanism (4) is driven. Insert/remove mechanism (4) until it aligns with the center of the front of cartridge (1a) in stocker (2).
) is moved. At this time, since the belt (71) is also driven in the same direction and at the same speed, the U-shaped connection fitting (75)
+J remains at the same height as the gripping opening.Next, the swing motor (44) of the gripping mechanism provided on the movable body (29) is activated, and the clamper (40) is opened. At the same time, the motor (31) is driven, and the moving body (
29) moves forward toward the cartridge (1a) K, and when the senna (64) detects the front of the cartridge (1a),
Forward movement is stopped. The swing motor (44) is de-energized, and the force of the mainspring spring inside the swing motor causes the clamper (
40) is closed and engages with the engaging parts provided on both sides of the cartridge (1a), and holds both front side surfaces of the cartridge (1a). In this way, use the U-shaped connection fitting (7
Since the convex portion 5) faces the stocker (2) side, the clamper (40) does not come into contact with the U-shaped connection fitting (75). Next, when the closed state of the clamper (4o) is confirmed by a sensor (not shown), the motor (31) rotates in the reverse direction [
, from the open end of the holder (28) to the closed end, and then pull in the cartridge (la). When the cartridge (la) is retracted to the position shown by the 24-dash line in Fig. 2, the motor (
10) and the support stand (63) are driven to move the cartridge gripping opening of the insertion/removal mechanism (4) to the center position of the insertion opening of the reproducing device (3). During this movement, a command is given to select the front and back sides of the cartridge (1a), and if necessary, the motor (23) is driven and the insertion/removal mechanism (4)

When all the movements are completed, the motor (31) is driven to advance the cartridge (1a). As the cartridge (1a) moves forward and is inserted into the playback device (3), a sensor (not shown) provided in the playback device (3)
is activated, and the driving of the motor (31) is stopped. At the same time, the swing motor (44) is energized and the clamper (40
) opens. , At this time, use the clamper (4) in the same manner as above.
0) will not hit the U-shaped connection fitting (75)K. When the expansion of the clamper (40) is completed, the motor (31) is reversed to retract the gripping mechanism. Next, the swing motor (
44) is de-energized to close the clamper (40) and enter a standby state.

When the recording or reproduction of the reproduction device ff (3) is completed, a command is issued to return the cartridge (1a) to its original position in the stocker (2). The operation at this time is the opposite of the operation described above. However, the difference is Rikiichi Toritsuji (1a
) is inserted into the stocker (2)K, the sensor (65) provided at the rear of the stocker (2) detects the cartridge (la).
) is detected and the driving of the 'C% motor (31) is stopped.

The cartridge (1) is held in its position by a retaining spring (87) provided on the stocker (2), and when vibrations, shocks, etc. exceeding the retaining force of this spring are applied, the cartridge (1) ), but at this time, the cartridge (
With the exception of 1), the other cartridges (1) do not pop out because their front ends touch the restraining belt (71). In addition, the cartridge (IHC) near the U-shaped connection fitting (75)
Even if the U-shaped connecting fitting (75) is located outside the opening surface of the stocker (2), there is no problem, and even when the insertion/removal mechanism (4) is moving up and down, the cartridge I) is not attached to the restraining belt (
71) The possibility of it flying out without hitting is very small.

〔Effect of the invention〕
