摘要： PURPOSE:To prevent the deformation of a tape to be wound in a pressing condi tion. CONSTITUTION:The tip part of a tape T is fixed to a tape clamping section 13, a tape hub 10 winding the tape in the direction of a hub circumference surface is formed in an almost cylinderical shape so that it is provided with a slit 14a in a cylindrical longitudinal direction and a hub ring 14 having elasticity in a radial direction is mounted on the circumference surface of the hub, as well. The clamp-fixed tape T is led out to the circumfernece surface of the hub ring 14 from the slit 14a and wound on the peripheral surface of the hub ring 14.

摘要： PURPOSE:To prevent a generation of a trace of splicing tape by forming the length of splicing tape to the length to meet the circumferential length of a cassette hub. CONSTITUTION:A magnetic tape 7 is wound around the cassette hubs 2, 3 through a leader tape 5 and splicing tape 6. At this time, the length of splicing tape 6 is formed to the length to meet the circumferential length of cassette hubs 2, 3 so that both ends of the tape 6 are not overlapped each other and closely positioned each other, when the splicing tape 6 is wound around the cassette hubs 2, 3. A step part caused by overlapping the tapes is thereby not produced, and the generation of so-called trace of splicing tape can be prevented.

摘要： PURPOSE:To prevent dropout of a magnetic tape caused from the deformation by substantially eliminating the deformation (deformation due to a pressing under the mattress) of edges at both sides of the magnetic tape due to the pressure at the time when the magnetic tape is wound around a reel hub. CONSTITUTION:The splicing tape is constituted of a film 3a, the width of which is nearly equivalent to or wider than those of the connected magnetic tape 1 and leader tape 2, and an adhesive layer 3b formed on the film 3a with the width narrower than those of the magnetic tape 1 and leader tape 2 on the film 3a.

摘要： PURPOSE:To obtain a measuring apparatus which can measure the circumferential deviation of a roller used as a drive roller or a corner roller, etc., of a data cartridge easily in the state similar to that under an actual service condition. CONSTITUTION:A pin 2 is inserted into a shaft hole 102 of a roller 101 as an object to be measured. The roller 101 is pressed to a measuring reference position of the circumferential surface of the pin 2. The deviation of the circumferential surface of the roller 101 is measured by an indicator 4 as the roller 101 is rotated.

摘要： PURPOSE:To prevent an elastic deformation part from cracking without directly giving stress to the elastic deformation part by providing a pressure releasing groove in an area where a tensile force applied from a disk part to a hub directly works on each elastic deformation part. CONSTITUTION:Plural releasing grooves 7 are formed in the neighborhood of a spindle hole 6, and plural elastic deformation parts 8 are comprised between the spindle hole 6. Also, the pressure releasing grooves 9 are formed at three places at the outer periphery of the hub 3, and they are provided in an inter- auxiliary line area drawn from the approximate center part of the deformation part 8 so as to pass the contact point of the hole 7 and spindle hole 6. Thereby, when the hub 3 shrinks more to a position shown by a virtual line inside than a hub hole 4a shown by a solid line, the tensile force works on the hub 4 from the disk part 4 in a radial direction as shown by arrows. The tensile force working on the inner groove 9 is not transmitted to the inside of the groove 9. Therefore, no tensile force from the disk part 4 is directly applied on the deformation part 8.

摘要： PURPOSE:To make a pawl part engage deeply into a guide groove and to improve the strength of attaching by setting a shutter in a case, pressing the connection part to the same level as the surface of the shutter and engaging to insert the pawl part into the guide groove. CONSTITUTION:In case of attaching the shutter 12 in the case 20 the shutter 12 is set in the case 20 in a state that the connection parts 29A and 29B between the pawl parts 28A and 28B of the shutter 12 and the plate shape part 26 are raised. And the connection parts 29A and 29B are pressed and the pawl parts 28A and 28B are engaged and inserted into the guide groove 13. At the time of setting the shutter 12 in the case 20, since the pawl parts 28A and 28B are not caught by an edge part 31, the length of the pawl parts 28A and 28B can be made long, so that the pawl parts 28A and 28B are deeply engaged into the guide groove 13 to improve the strength of mounting.

摘要： PURPOSE:To prevent a tape winding from loosening by pressing a leader tape to the outside of a reel hub. CONSTITUTION:An elastic plate 12 is provided on the outer periphery of reel hub 3, then the leader tape is elastically pressed to the outward direction of reel hub 3 and made tense. By this procedure, the loose winding of magnetic tape 4 caused from vibration, etc., can be eliminated. Consequently, erroneous loading of tape cassette and tape damages such as a jamming, etc., can be prevented beforehand.
