Abstract

Abstract A reel table assembly for driving a tape reel (9) which has a center hole (10) and a plurality of equally spaced inwardly extending radial teeth (11) formed circumferentially thereof comprises a reel table (2) formed centrally with a reel shaft (3) for carrying thereon the tape reel (9) with the center hole (10), and a plurality of equally spaced drive pawls (4) which are provided circumferentially in the reel shaft (3) and project radially outwardly of the reel shaft (3) under a resilient force for mesh engagement with the radial teeth (11) of the tape reel (9). The drive pawls (4) are movable radially inwardly of the reel shaft (3) when the tape reel (9) is carried on the reel table (2) with the radial teeth (11) being in radial abutment on the drive pawls (4). A friction member (5) is provided on the reel table (2) for direct contact with the tape reel (9) to provide a high degree of friction between the reel table (2) and the tape reel (9) carried on the reel table (2). The reel table (2) also comprises a low-friction means (20) provided on the reel table (2) for direct contact with the tape reel (9) to maintain the tape reel (9) lifted off the friction member (5) only when the tape reel (9) is carried on the reel table (2) with the radial teeth (11) being in radial abutment with the drive pawls (4).

A reel table assembly for driving a tape reel
Claim 3
Dependent Claim 226 words
(9) having a center hole (10) formed therein and a plurality of inwardly extending radial teeth (11) formed circumferentially of the center hole (10), the reel table assembly comprising: a reel table (2) formed centrally with a reel shaft (3) for carrying thereon the tape reel (9) with the center hole (10); a friction member (5) provided on said reel table (2) for direct contact with the tape reel (9) to provide a high degree of friction with the tape reel (9) carried on said reel table (2); and a drive pawl means (4) provided circumferentially in said reel shaft .(3), said drive pawl means (4) projecting radially outwardly of said reel shaft (3) under a resilient force for mesh engagement with the radial teeth of the tape reel (11), said drive pawl means (4) being movable radially and inwardly of said reel shaft (3) when the tape reel (9) is carried on said reel table (2) with the radial teeth (10) being in radial abutment on said drive pawl means (4); characterized by low-friction means (20) provided on said reel table for direct contact with the tape reel (9) to maintain the tape reel (9) lifted thereoff only when the tape reel (9) is carried on said reel table (2) with the radial teeth (11) being in radial abutment with said drive pawl means (4).
Claim 4
Dependent Claim 226 words
(9) having a center hole (10) formed therein and a plurality of inwardly extending radial teeth (11) formed circumferentially of the center hole (10), the reel table assembly comprising: a reel table (2) formed centrally with a reel shaft (3) for carrying thereon the tape reel (9) with the center hole (10); a friction member (5) provided on said reel table (2) for direct contact with the tape reel (9) to provide a high degree of friction with the tape reel (9) carried on said reel table (2); and a drive pawl means (4) provided circumferentially in said reel shaft .(3), said drive pawl means (4) projecting radially outwardly of said reel shaft (3) under a resilient force for mesh engagement with the radial teeth of the tape reel (11), said drive pawl means (4) being movable radially and inwardly of said reel shaft (3) when the tape reel (9) is carried on said reel table (2) with the radial teeth (10) being in radial abutment on said drive pawl means (4); characterized by low-friction means (20) provided on said reel table for direct contact with the tape reel (9) to maintain the tape reel (9) lifted thereoff only when the tape reel (9) is carried on said reel table (2) with the radial teeth (11) being in radial abutment with said drive pawl means (4).
Claim 5
Dependent Claim 123 words
The reel table as claimed in claim 1, characterized in that said low-friction means (20) comprises at least one projection formed on said reel shaft (3) at a position spaced circumferentially from said drive pawl means (4), said projection having a width permitting mesh engagement of said projection with the radial teeth (11) when the tape reel (9) is carried on said reel table (2) with said drive pawl means (4) being in mesh engagement with the radial teeth (11), said projection (20) having a height lifting the tape reel (9) off said friction member (5) when the tape reel (9) is carried on said reel table (2) with the radial teeth (11) being in radial abutment with said drive pawl means (4).
Claim 6
Dependent Claim 29 words
The reel table as claimed in claim 2, characterized in that said low-friction means (20) comprises a plurality of equally spaced projections formed circumferentially on said reel shaft (3).
Claim 7
Dependent Claim 29 words
The reel table as claimed in anyone of claims 1 to 3, characterized in that said drive pawl means (4) comprises a plurality of equally spaced drive pawls (4).
Claim 8
Dependent Claim 28 words
The reel table as claimed in claim 4, characterized in that the number of said drive pawls (4) is divided that of the radial teeth (11) by integral.
Claim 9
Dependent Claim 111 words
The reel table as claimed in claim 1, characterized in that said low-friction means (20) comprises at least one projection formed on said reel table (2), said projection having a width permitting mesh engagement of said projection with the radial teeth (11) when the tape reel (9) is carried on said reel table (2) with said drive pawl means (4) being in mesh engagement with the radial teeth (11), said projection having a height lifting the tape reel (9) off said friction member (20) when the tape reel (9) is carried on said reel table (2) with the radial teeth (11) being in radial abutment with said drive pawl means (4).
Claim 10
Dependent Claim 33 words
The reel table as claimed in claim 6, characterized in that said low-friction means (20) comprises a plurality of equally spaced projections formed on said reel table (2) around said reel shaft (3).
