To provide a tape cartridge capable of preventing an area near the posterior rim a tape winding layer from colliding with a casing wall to cause the tape edge to be damaged upon reception of dropping impact in the state where the upper and lower sides of the tape cartridge are reversed, so that the magnetic tape can constantly be maintained in an appropriate state. A pair of right and left hubs for taking up the magnetic tape, a hub locking structure are provided inside a main casing. The hub lo...

A tape feeder including an electronic component accommodating part installed at one side of a tape feeder main body to accommodate electronic components which are not picked up by a suction nozzle of an electronic component conveyance robot installed at an electronic component mounting device, thereby preventing the electronic components from clogging a carrier tape moving path, and storing the electronic components in the electronic component accommodating part. Therefore, it is possible to inc...

A tape dispenser includes a rotatable support for a tape roll, a rotatable applicator roll, and a swing gate for guiding tape to be dispensed from the tape roll to the applicator roll. The dispenser also includes a cutting element for severing predetermined lengths of tape from the tape roll. A locking element for releasably locking the applicator roll in a stationary position is selectively activated by a trigger to enable the dispensed tape to be firmly applied to a workpiece and to enable the...

The tape measure may consist of a relatively large tape blade. To accommodate a large blade the tape measure housing is formed as a hollow annulus having an open central core where the blade is wound about the core of the annular housing. Because the housing has a central opening it can be easily carried in one hand. The device also includes a locking mechanism for locking the tape in an extended position and a rewind mechanism for rewinding the tape back into the housing. The rewind mechanism m...

A tape measure comprises a housing having a tape outlet opening. A flexible measuring tape is movable between a retracted position in which the measuring tape is substantially disposed within the housing, and an extended position in which at least a portion of the measuring tape extends through the tape outlet opening and linearly outside the housing. The measuring tape has a free end and a pair of longitudinal edges, and the measuring tape has measuring indicia displayed thereon. A magnifying l...

A magnetic tape which is run at a speed of 4 m/sec. or higher and has recording tracks with a width of 21 .mu.m or less, and which includes a non-magnetic support, at least one magnetic layer formed on one surface of the non-magnetic support, and a backcoat layer formed on the other surface of the non-magnetic support, wherein servo signals for controlling tracking are recorded on the magnetic layer or the backcoat layer, the value of (.alpha./W).times.(V/f) is 10 [s.sup.-1] or less, and/or the ...

A method for avoiding tape stiction is provided with a tape drive with a pair of motors for driving a pair of tape reels for conveying data tape across one or more read/write heads. Tachometers measure rotation of the pair of tape reels. Motion of the tape is started and rotation of the tape reels is measured by the tachometers. The measurement of the rotation of the tape reels is compared to determine if there is enough slack associated with tape stiction. The location of tape stiction is store...

A TAB tape for a tape carrier package may have an opening formed in a shortest connection portion. The opening may be provided in the shortest connection portion and a portion of the corresponding second lead. The opening may be arranged near a boundary between the corresponding first lead and the shortest connection portion. The opening may be sized to reduce the change of the lead width from the first lead to the second lead.

A tape reel for a tape cassette includes stabilizing ribs positioned on opposite sides of a deposition rib. The stabilizing ribs are lower in height than the deposition rib and are provided with an abutment surface which extends parallel to the joining surfaces of the reel hub and reel flange. As the deposition rib is melted to join the reel hub and reel flange together, the melt distributes uniformly between the joining surfaces of the reel hub and reel flange, thereby preventing any deformatio...

A tape cartridge includes a reel and a data tape to store data. The data tape is wound on the reel and has side edges. The tape cartridge further comprises a leader tape, and a splicing tape to link the leader tape to the data tape. The splicing tape has an edge with a slanted portion that is slanted with respect to the side edges of the data tape.
