Definitions

  • the present invention relates to a tape driver for use in a tape recorder or similar devices which use a data cartridge having a drive roller.
  • tape recorders and similar devices use a data cartridge which contains magnetic tape wound on a pair of reels.
  • the data cartridge provides a drive roller which is coupled to the reels by a drive belt.
  • a conventional tape driver includes a pulley mounted on the rotary shaft of a motor.
  • the motor is located under the data cartridge when the data cartridge is loaded into the tape recorder.
  • a conventional tape driver rotates the drive roller so as to turn the reels and run the magnetic tape as disclosed in Japanese Patent Application Examined Publication No. 14976/77.
  • the height of a tape recorder or similar device cannot be made less than the sum of the thickness of the data cartridge and the height of the motor in a conventional tape driver. Furthermore, the close proximity of the motor to the magnetic head adversely affects performance.
  • An object of the present invention is to reduce the minimum height of a tape recorder or similar device employing a tape driver and a data cartridge.
  • Another object of the present invention is to locate a tape driver in a tape recorder in a position lateral to the data cartridge such that combined height of the tape driver and data cartridge is reduced.
  • Another object of the present invention is to reduce the adverse effects of the motor on the magnetic head by increasing the separation of the motor and magnetic head.
  • a tape driver for engaging a drive roller provided in a data cartridge to rotate the drive roller to run magnetic tape contained in the data cartridge, comprising a motor unit laterally disposed relative to the data cartridge and an idler located between the motor unit and the drive roller, wherein the motor unit rotates the drive roller through the idler.
  • a tape driver for engaging a drive roller provided in a data cartridge to rotate the drive roller to run magnetic tape contained in the data cartridge, comprising a motor unit laterally disposed relative to the data cartridge and means rotatably driven by the motor unit for directly rotating the drive roller.
  • FIG. 1 is a plan view of a tape recorder employing a tape driver which is an embodiment of the present invention
  • FIG. 2 is a perspective view of a data cartridge to be loaded in the tape recorder
  • FIG. 3 is a perspective view of the front of the data cartridge
  • FIGS. 4A and 4B are schematic illustrations of the inside of the data cartridge
  • FIG. 5 is a side view of the tape driver
  • FIG. 6 shows the positional relationship between the tape driver and the data cartridge when the data cartridge is loaded in the tape recorder.
  • FIG. 1 shows a tape recorder 2 employing a tape driver 1 which is an embodiment of the present invention.
  • the components of the tape driver 1 are all disposed on the top of the chassis 38.
  • the tape recorder 2 includes in addition to tape driver 1, a magnetic head 3, and a data cartridge load/unload mechanism not shown in the drawings.
  • the magnetic head 3 attaches to a head holder 17 which is supported by pins 19 and 20 planted in a base 18.
  • the head holder 17 and base 18 can be moved up and down, but are urged by helical springs 21 and 22 such that magnetic head 3 is stably held once positioned.
  • a data cartridge 5 is removably loaded in the tape recorder 2 such that magnetic recording or reproduction is performed.
  • FIG. 2 shows the data cartridge 5.
  • the cassette-like body 6 has guide grooves 6a and 6b along the side and locking notches 7a and 7b towards the lower front.
  • the data cartridge 5 includes a rotatably attached door 8 on the front which is usually closed to prevent dust from entering into the body 6.
  • the end 8a of the door 8 is engaged with the guide rail 10b shown in FIG. 1, so that the door is opened to expose magnetic tape 11 as shown in FIG. 3.
  • the data cartridge 5 also incudes a drive roller 9 located at notch 6c on the front as shown in FIG. 3.
  • FIG. 4 shows the interior of the data cartridge 5 and a pair of reels 12 and 13 on which magnetic tape 11 is wound.
  • a drive belt 16 fits tightly on the drive roller 9 and guide rollers 14 and 15 and extends between the drive roller 9 and guide rollers 14 and 15 so as to contact the peripheral surfaces of magnetic tape windings 11a and 11b on the reels 12 and 13 respectively.
  • the drive belt 16 revolves around the drive roller 9 and guide rollers 14 and 15.
  • the drive belt 16 turns the magnetic tape windings 11a and 11b so that the reels 12 and 13 rotate and run the magnetic tape 11.
  • the tape driver 1 includes motor unit 23, base 24, torsion spring 25, and idler 26.
  • the motor unit 23 includes motor 27, rotary shaft 28, and pulley 29.
  • the motor 27 mounts on the base 24 which is pivotally coupled to pin 36 planted in chassis 38.
  • the torsion spring 25 fits onto the pin 36 and engages pin 37 on one end and the base 24 on the other end.
  • the torsion spring 25, thus urges the base 24 to turn clockwise about the pin 36.
  • a stopper mechanism provided under the motor unit 23, but not shown in the drawings, restricts the turn of the base 24 to the position of FIG. 1.
  • Pin 31 which is planted in one end of arm 30 rotatably supports idler 26.
  • Torsion spring 33 fits onto the pin 32 and engages the base 24 on one end and the arm 30 on the other end. The torsion spring 33, thus urges the arm 30 by a weak force to turn counterclockwise about the pin 32.
  • the idler 26 places the motor unit 23 lateral to the data cartridge 5 which is typically limited to a height no less than the sum of the thickness of the data cartridge and the height of the body of the motor.
  • the motor 27 is placed further away from the magnetic head 3.
  • Increased distance between the motor 27 and the magnetic head 3 diminishes the adverse influence of the motor on the magnetic head and facilitates shielding of the magnetic head.
  • the diameter of the pulley 29 may be increased to directly rotate the drive roller 9.
  • the idler 26 is provided to reduce the diameter of pulley 29 which rotates the drive roller 9 at high rotary power through the medium of idler 26.
