A reel holder for use in a tape winding apparatus comprises a cylindrical drum unit which is rotated by the tape winding apparatus. A plurality of lock pins are radially movably mounted in a peripheral portion of the drum unit. Each each lock pin is axially movable between a projected position wherein an outer end thereof is projected outwardly from a cylindrical outer wall of the drum unit and a retracted position wherein the outer end thereof is retracted into the drum unit. First and second buttons are mounted on an axial end of the drum unit. Each button is movable in parallel with the axis of the drum unit between raised and depressed positions with respect to the axial end of the drum unit. A transmission device is installed in the drum unit and operated in such a manner as to move the lock pins to the projected position when the first button is moved to the depressed position and permit the lock pins to return to the retracted position when the second button is moved to the depressed position.

Reel holder for use in tape winding apparatus

A tape winding apparatus, in which a tape drawn from a pancake reel and loaded onto a reel base is wound and accommodated within a cassette, includes a pancake reel exchanging apparatus, wherein at least two pancake reels coaxially disposed with respect to the axial direction of the reel base are loaded onto the reel base. Therefore, a plurality of pancake reels can be loaded onto this tape winding apparatus and the tape winding apparatus can be made comparatively small in size.

A linear scale features a removable scale channel and adjustable head assembly for easy, accurate, permanent positioning on a machine tool bed or other mobile device. The scale channel, and a matching positioning tool, has balls at opposite ends engaging a socketed mounting bracket. When in use, the flexible socket coupling is clamped into immobility by removable covers over open faces of the mounting brackets. During installation, the mounting brackets engage the positioning tool rather than the scale channel and with the flexible-socket couplings free to gimbal. The mounting brackets are fixed to the machine tool at a fixed axial spacing determined by the length of the positioning tool but at whatever angular attitude best suits the supporting surface of the machine tool. The positioning tool is then removed and replaced by the scale channel. The head assembly is fixed to a stationary stand opposite the scale channel. An adjustable mechanism allows the sliding head of the head assembly to move perpendicular to the axial direction relative to a base fixed to the stand.
