US3884341A — Paper strip transport and printing mechanism havi…

Claim 1

Independent Claim 296 words

A paper strip transport and printing mechanism comprising: a supply source for supplying paper strip; take-up means for taking up the paper strip; feeding means for feeding forwardly the paper strip taken from said supply source, said feeding means including a feed-roller engaging the paper strip, and a feed-roller gear rigidly connected to said feed-roller; printing means positioned in front of said feeding means for printing on said paper strip; and, actuating means for actuating said feeding means, said printing means and said take-up means, said actuating means including: a single drive means, first transmission means for operatively connecting said drive means to said printing means to actuate said printing means, said first transmission means including ancillary transmission means for actuating said feeding means in a predetermined time relation to the actuation of said printing means, and, second transmission means for connecting said drive means with said take-up means to actuate said take-up means to take up the paper strip moved forward by said feeding means, said first transmission means including a first shaft keyed to said printing means, and cam-follower means operatively connecting said drive means to said first shaft for imparting thereto a reciprocative motion in response to a movement of said drive means; and, said ancillary transmission means comprising a ratchet wheel rotatively mounted on said first shaft so as to be freely rotative with respect thereto, said ratchet wheel being equipped with a gear wheel for engaging said feed-roller gear, and a pawl for coacting with said ratchet wheel, said pawl being operatively connected to said first shaft so as to be actuated by the reciprocative motion of said first shaft to turn said ratchet wheel in a direction for turning said feed-roller in a direction to feed the paper strip forward.

Claim 2

Dependent Claim 296 words

A paper strip transport and printing mechanism comprising: a supply source for supplying paper strip; take-up means for taking up the paper strip; feeding means for feeding forwardly the paper strip taken from said supply source, said feeding means including a feed-roller engaging the paper strip, and a feed-roller gear rigidly connected to said feed-roller; printing means positioned in front of said feeding means for printing on said paper strip; and, actuating means for actuating said feeding means, said printing means and said take-up means, said actuating means including: a single drive means, first transmission means for operatively connecting said drive means to said printing means to actuate said printing means, said first transmission means including ancillary transmission means for actuating said feeding means in a predetermined time relation to the actuation of said printing means, and, second transmission means for connecting said drive means with said take-up means to actuate said take-up means to take up the paper strip moved forward by said feeding means, said first transmission means including a first shaft keyed to said printing means, and cam-follower means operatively connecting said drive means to said first shaft for imparting thereto a reciprocative motion in response to a movement of said drive means; and, said ancillary transmission means comprising a ratchet wheel rotatively mounted on said first shaft so as to be freely rotative with respect thereto, said ratchet wheel being equipped with a gear wheel for engaging said feed-roller gear, and a pawl for coacting with said ratchet wheel, said pawl being operatively connected to said first shaft so as to be actuated by the reciprocative motion of said first shaft to turn said ratchet wheel in a direction for turning said feed-roller in a direction to feed the paper strip forward.

Claim 3

Dependent Claim 47 words

The mechanism of claim 1, said second transmission means including means for frictionally engaging said take-up means so as to cause said take-up means to take up the paper strip while simultaneously keeping the paper strip taut irrespective of the quantity of paper strip taken up thereby.

Claim 4

Dependent Claim 118 words

The mechanism of claim 1, said drive means comprising a rotatable drive shaft; said take-up means being a take-up roller for rolling up the paper strip fed by said feeding means whereby a paper-strip roll of changing diameter builds up on said take-up roller; and, said second transmission means comprising: a drive wheel connected to said drive shaft, a friction wheel, and a belt for connecting said drive wheel to said friction wheel for driving the said friction wheel, said friction wheel frictionally engaging said take-up roller so as to overdrive said take-up roller whereby the paper strip rolled onto said take-up roller is kept taut regardless of changes in the diameter of the paper-strip roll rolled thereon.

Claim 5

Dependent Claim 31 words

The mechanism of claim 3 comprising means for pressing said take-up roller against said friction wheel and for accommodating the take-up roller to facilitate the removal of a printed strip roll.

Claim 6

Dependent Claim 99 words

The mechanism of claim 3, wherein said reciprocative motion of said first shaft operates to move said printing means between first and second positions whereat said printing means prints on and is separated away from the paper strip respectively, said pawl engaging the teeth of said ratchet wheel during the movement Of the printing means from said first position to said second position whereby said feed-roller is actuated to move the paper strip forward in time sequence ahead of the movement of said printing means from said second position to said first position to print on the paper strip.

Claim 7

Dependent Claim 31 words

The mechanism of claim 5 comprising means for pressing said take-up roller against said friction wheel and for accommodating the take-up roller to facilitate the removal of a printed strip roll.

Claim 8

Dependent Claim 48 words

The mechanism of claim 1, said drive means comprising a rotatable drive shaft, a cam-disc mounted on said drive shaft, and a cam-follower connected to said first shaft whereby the reciprocative motion of said first shaft is produced in response to a unidirectional rotative motion of said cam-disc.

Claim 9

Dependent Claim 99 words

The mechanism of claim 1, wherein said reciprocative motion of said first shaft operates to move said printing means between first and second positions whereat said printing means prints on and is separated away from the paper strip respectively, said pawl engaging the teeth of said ratchet wheel during the movement of the printing means from said first position to said second position whereby said feed-roller is actuated to move the paper strip forward in time sequence ahead of the movement of said printing means from said second position to said first position to print on the paper strip.

Claim 10

Dependent Claim 48 words

The mechanism of claim 8, said drive means comprising a rotatable drive shaft, a cam-disc mounted on said drive shaft, and a cam-follower connected to said first shaft whereby the reciprocative motion of said first shaft is produced in response to a unidirectional rotative motion of siad cam-disc.
