The tension adjusting unit 15 continues to apply a predetermined constant tension to the magnetic tape 60 as the dancer roller 26 moves in a direction toward or away from the second and fourth guide rollers 25 and 27. The roller 24 is a measuring roller.

  The cleaner unit 16 is arranged on the downstream side of the tension adjusting unit 15 in the running direction of the magnetic tape 60, and has a first cleaner unit 28 and a second cleaner unit 29 for cleaning both the front and back surfaces of the magnetic tape 60 facing each other. is doing.

  The first cleaner section 28 includes a main roller 30, guide rollers 31 and 32, a cleaning tape feed reel 34, and a cleaning tape take-up reel 33, and a cleaning tape 35 is wound around the first cleaner section 28. In the first cleaner section 28, the cleaning tape take-up reel 33 and the cleaning tape delivery reel 34 are synchronously rotated by a drive motor (not shown), so that the cleaning tape 35 stretched around the main roller 30 is kept at a constant speed. The cleaning tape 35 is pressed against the magnetic tape 60 and the dirt adhering to the surface of the magnetic tape 60 is wiped off.

  The second cleaner section 29 includes a main roller 36, a guide roller 37, a cleaning tape feed reel 39, and a cleaning tape take-up reel 38, and a cleaning tape 40 is wound around the second cleaner section 29. In the second cleaner section 29, the cleaning tape take-up reel 39 and the cleaning tape delivery reel 38 are rotated synchronously by a drive motor (not shown), so that the cleaning tape 40 stretched over the main roller 36 is kept at a constant speed. The cleaning tape 40 is pressed against the magnetic tape 60 on the downstream side of the first cleaner unit 28 to wipe off the dirt adhering to the surface of the magnetic tape 60.

  Here, as the cleaning tapes 35 and 40, a nonwoven fabric mainly composed of polyester, rayon, nylon, cotton, or a cloth manufactured using Japanese paper or the like can be used.

  The tape drive capstan unit 17 is disposed downstream of the cleaner unit 16 in the tape traveling direction, and includes a capstan roller 41 and a pressure roller 42. In the capstan unit 17, a drive motor (not shown) coupled to the capstan roller 41 is connected to the tape drive unit 14, and the magnetic tape 60 stretched over the capstan roller 41 is pressed by the pressure roller 42. Driven in close contact with the capstan roller 41 without slipping. In this way, the capstan unit 17 moves the magnetic tape 60 toward the winding side rotating unit 13 in accordance with a predetermined signal given from the control unit 19 together with the feeding side rotating unit 12 and the winding side rotating unit 13. Drive at a constant speed. A winding side rotating part 13 is arranged downstream of the capstan part 17.

  The operation unit 18 includes a manual mode / automatic mode switch, a start switch and a stop switch in the automatic mode, and a tape start switch / tape stop switch and a blower 21 for starting and stopping the tape drive unit 14 in the manual mode. Is a control panel having a blower start switch, a blower stop switch, and the like for starting and stopping the printer, and gives control signals to the tape drive unit 14 and the blower 21 through the electrically connected control unit 19.

  The control unit 19 includes an electronic circuit in which a control element such as a CPU is incorporated. When a start signal is input by operating the operation unit 18, the control unit 19 supplies driving power to the tape drive unit 14 and the blower 21 based on the logic of the built-in logic circuit. Further, when a stop signal is given by the operation of the operation unit 18, the control unit 19 stops the power supply to the tape drive unit 14 and the power supply to the blower 21 based on the logic of the logic circuit.

The casing 20 is provided so as to cover the cleaner unit 16 and the tape drive capstan unit 17 that generate a large amount of dust. For example, the casing 20 has a box shape having two pairs of side plates 43, 44, 45, 46 and a top plate 47. Is formed. In the present embodiment, in the casing 20, the long side plates 43 and 44 have a length of 500 mm, for example, and the short side plates 45 and 46 have a length of 400 mm and have a height. However, it has a length of, for example, 150 mm, and the inner volume of the casing 20 is about 3000 cm ³ . The outer shape of the cleaner 16 and the capstan 17 is fixed to the base 11. A slit-shaped tape inlet 48 is formed in the side plate 45 in the vicinity of the tension adjusting unit 15 arranged on the upstream side in the magnetic tape running direction, and the side plate 43 in the vicinity of the winding side rotating unit 13 on the downstream side. The tape outlet 49 is formed.
The tape carry-out port 49 is formed in a slit shape having a tapered shape in which the opening area increases from the inside to the outside of the casing 20, and the blower suction port 50 is formed in the side plate 44 disposed on the opposite side of the side plate 43. Has been. The blower suction port 50 has an inner diameter of φ30 mm, for example.

  The tape carry-in port 48 is disposed between the fourth guide roller 27 of the tension adjusting unit 15 and the guide roller 31 of the cleaner unit 16, and the magnetic tape 60 delivered from the fourth guide roller 27 is accommodated in the casing 20. Take it straight in. The tape carry-in port 48 also functions as an intake port that takes in fresh (less dust) air into the casing 20 while the blower 21 is operating.

  The tape carry-out port 49 is arranged between the capstan roller 41 of the tape drive capstan unit 17 and the shaft 23 of the winding side rotation unit 13, and the magnetic tape sent from the tape drive capstan unit 17. 60 is sent out linearly toward the shaft 23 of the winding side rotation unit 13. Further, the tape carry-out port 49 also functions as an intake port that takes in fresh air into the casing 20 while the blower 21 is operating. And since the tape carry-out port 49 has a tapered shape that gradually becomes wider toward the downstream side in the running direction of the magnetic tape 60, when the magnetic tape 60 runs and is carried out of the casing 20, The fresh air outside the casing 20 is blown against the surface of the magnetic tape 60 in the direction opposite to the direction of movement of the accompanying air on the surface of the magnetic tape 60 (the conveying direction of the magnetic tape). It is reliably prevented from being carried out of the casing 20 as it is along the magnetic tape 60. Further, by arranging the tape unloading direction of the tape unloading port 49 and the direction of air suction by the blower 21 so as to be substantially coaxial and opposite to each other, the suction efficiency is increased, and the accompanying air is transferred to the magnetic tape 60. The effect of peeling from the surface can be increased.

The blower 21 is a suction machine that generates a suction force exceeding 2 kPa at its operation, for example, at 0.45 m ³ / min, and the blower body 51 is installed separately from the tape traveling device 10. One end of the duct 52 communicated with the blower main body 51 is connected to and connected to the blower suction port 50 of the casing 20, and the other end of the duct 52 communicates with the blower main body 51 outside through the outer plate 53. Connected. In the blower 21, the blower body 51 starts suction by the control signal given from the control unit 19, and the blower sucks the dust generated from the cleaner unit 16 and the tape drive capstan unit 17 and scattered in the casing 20. The dust is sucked from the mouth 50 and the dust is carried out of the casing 20. A pressure gauge 54 for measuring the suction pressure by the blower 21 is disposed inside the duct 52.

  In such a tape traveling device 10, the pancake is attached to the delivery-side rotating unit 12, and the tape driving unit 14 is driven by a predetermined control signal given from the control unit 19, whereby the tape driving capstan unit Together with the 17 capstan rollers 41, the magnetic tape 60 starts to travel at a constant speed between the feed-side rotating unit 12 and the winding-side rotating unit 13. The magnetic tape 60 that has started running is fed into the casing 20 from the tape carry-in port 48 of the casing 20 while the tension is adjusted by the tension adjusting section 15, and the cleaning tape 35, 40, the dirt on the front and back surfaces of the magnetic tape 60 is wiped off. Then, it is sent out from the tape carry-out port 49 of the casing 20 via the tape drive capstan part 17 and taken up at the take-up side rotating part 13.

  In the above operation, when the magnetic tape 60 starts running, dust is generated in the cleaner unit 16 and the tape drive capstan unit 17 to start the operation of the blower 21 based on the logic of the logic circuit in the control unit 19. The dust scattered in the casing 20 is forcibly removed by suction. At that time, since the blower suction port 50 is disposed on the downstream side of the traveling path of the magnetic tape 60 and facing the tape carry-out port 49 of the casing 20, the magnetic tape 60 cleaned in the cleaner unit 16 is disposed. The dust moving along with the magnetic tape 60 on the accompanying air moving along the traveling direction of the magnetic tape 60 can be removed from the surface of the magnetic tape 60 to efficiently collect the dust. As a result, the magnetic tape 60 that has been subjected to the cleaning process can be wound up without adhering dust, and the quality of the magnetic tape 60 can be improved.

Next, operation start control by the first tape cleaning method using the tape traveling device 10 will be described with reference to FIG. FIG. 2 is a flowchart for explaining the operation start control of the first tape cleaning method using the tape running device shown in FIG.
In the first tape cleaning method using the tape traveling device 10, the operation of the magnetic tape 60 is started after the logic circuit logic by the control unit 19 starts air suction by the blower 21 at the start of operation. It is set.

  When the start switch of the operation unit 18 is pressed (S11), first, the blower 21 is activated and air is sucked from the casing 20 (S12). Then, the suction pressure by the blower 21 is measured by the pressure gauge 54, and when it is confirmed that the difference from the atmospheric pressure exceeds 2 kPa (S13), the tape drive is turned on by turning on the drive of the tape drive unit 14. Start (S14).

  In this tape cleaning method, since the air suction by the blower 21 is started before the running of the magnetic tape 60 is started, the blower 21 exhibits a stable suction capability in a steady state, so that the inside of the casing 20 After the air flow is stabilized, the generated dust can be collected efficiently.

  When the inner volume of the casing 20 is small, the time from the suction start of the blower 21 to the stable state is short, so the logic of the logic circuit by the control unit 19 is set as the travel start timing of the magnetic tape 60. The air suction start timing by the blower 21 may be set at the same time. FIG. 3 shows a flowchart in this case. That is, when the start switch is pressed (S21), the suction by the blower 21 is turned on and the drive of the tape drive unit 14 is turned on (S22). Even with such control, the generated dust and the dust moving on the accompanying air can be reliably collected.

Next, operation stop control of the second tape cleaning method using the tape traveling device 10 will be described with reference to FIG. FIG. 4 is a flowchart for explaining the operation stop control of the second tape cleaning method using the tape running device shown in FIG.
In the second tape cleaning method using the tape traveling device 10, when the operation is stopped, the logic of the logic circuit by the control unit 19 stops the air suction by the blower 21 after stopping the traveling of the magnetic tape 60. It is set.

  When the stop switch of the operation unit 18 is pressed (S31), first, the drive of the tape drive unit 14 is turned off (S32). Then, it is confirmed that the tape running has been stopped by determining whether a predetermined time has elapsed after the drive is stopped (S33), and thereafter the suction of the blower 21 is stopped (S34).

  In the second tape cleaning method using the tape traveling device 10, after the traveling of the magnetic tape 60 is stopped, in order to stop the air suction by the blower 21, dust is collected together with the magnetic tape 60 carried out from the casing 20. It is possible to prevent going out of the casing 20 in advance.

  If the time constant of the control of the tape drive unit 14 is small, the time from the drive stop until the magnetic tape 60 actually stops running is very short. Therefore, the logic of the logic circuit by the control unit 19 is changed to the magnetic tape. The travel stop timing of 60 and the air suction stop timing by the blower 21 may be set simultaneously. FIG. 5 shows a flowchart in this case. That is, when the stop switch is pressed (S41), the drive of the tape drive unit 14 is turned off and the suction by the blower 21 is turned off (S42). Even with such control, the generated dust and the dust moving on the accompanying air can be reliably collected.

  According to the tape traveling device 10 described above, the cleaner unit 16 and the tape drive capstan unit 17 are covered by the casing 20, and the air in the casing 20 is sucked by the blower 21, so that the magnetic tape 60 is cleaned. Dust that is generated and scattered in the casing 20 is sucked by the blower 21. As a result, dust that has been generated does not adhere to the magnetic tape 60 that has been cleaned once, so that the quality of the magnetic tape 60 that has been cleaned can be improved.

Further, according to the tape traveling device 10, since the volume of the casing 20 is 2000 to 3000 cm ³ and the suction force of the blower 21 is 2 kPa or more, dust scattered in the casing 20 is efficiently removed. Can collect dust.

  Each tape cleaning method for operation start control using the tape traveling device 10 described above can be appropriately combined with each tape cleaning method for operation stop control.

Next, with reference to FIG. 6, the Example performed in order to confirm the effect of the tape traveling apparatus 10 which concerns on this invention, and the tape cleaning method using the same is demonstrated.
Here, a predetermined time (1 hour), definitive after a cleaning process by driving the tape running ^{device, 1ft 3 (0.3048 3 m 3} ≒ 0.02832m 3) per φ0.5μm more dust Investigated the total number of. The results are shown in Table 1 below.

  As shown in Table 1, in the conventional tape running device without a casing, 600,000 near the cleaner section 16, 140,000 near the tape drive capstan section 17, 300 near the operation section, In the vicinity of the winding side rotating part, 22,000 dusts were confirmed. Here, the dust generation source is mainly the cleaner unit 16 and then the tape drive capstan unit 17. Note that the operation unit 18 and the winding side rotating unit (winding unit) 13 have high values due to dust or the like mixed in the accompanying air on the surface of the magnetic tape.

  On the other hand, in the tape traveling device 10 of the present invention, 40,000 near the cleaner 16, 17,000 near the capstan 17, 30 near the operation unit 18, take-up side rotation In the vicinity of the portion 13, 2,600 dusts were confirmed. This is a result of demonstrating that the cleaner unit 16 and the capstan unit 17 are covered with the casing 20, and air containing dust in the casing 20 is sucked by the blower 21. As a result, the dust generated is no longer attached to the magnetic tape 60 that has been cleaned once, and the quality of the wound magnetic tape 60 after the cleaning processing can be improved.

Note that the tape running device of the present invention and the tape cleaning method using the same are not limited to the above-described embodiments, and can be appropriately modified and improved.
For example, the internal volume of the casing can be appropriately changed in consideration of the suction force of the blower, the inner diameter of the blower suction port, and the like. Further, the casing may be integrally formed on the base except for the top plate without being fixed on the base. Moreover, you may use other dust collection systems, such as electrostatic adsorption, or you may use together with another system.

  Moreover, the cleaner part may be single, or may be arrange | positioned three or more, without arrange | positioning in a pair.
