Abstract
Abstract A thermal printing apparatus has a pair of transporting rollers for transporting a medium to be printed, a head angle member which holds a thermal head at right angles to a direction of transporting the medium transported by the pair of transporting rollers and which is pivotally supported at one end thereof, and a device for pivoting the head angle member so as to move the thermal head towards and away from the medium. The apparatus further has a shaft moving device which moves a shaft for mounting thereon the head angle member depending on a thickness of the medium.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
106 words
A thermal printing apparatus having: a pair of transporting rollers for transporting a medium to be printed; a head angle member that holds a thermal head at a right angle to a plane in which the medium transported by said pair of transporting rollers lies and that is pivotally supported at one end thereof; and a head angle member pivoting means that pivots said head angle member so as to move said thermal head toward and away from the medium; wherein said apparatus further comprises shaft moving means for moving a shaft for mounting thereon said head angle member depending on a thickness of the medium.
Claim 2
Dependent Claim
106 words
A thermal printing apparatus having: a pair of transporting rollers for transporting a medium to be printed; a head angle member that holds a thermal head at a right angle to a plane in which the medium transported by said pair of transporting rollers lies and that is pivotally supported at one end thereof; and a head angle member pivoting means that pivots said head angle member so as to move said thermal head toward and away from the medium; wherein said apparatus further comprises shaft moving means for moving a shaft for mounting thereon said head angle member depending on a thickness of the medium.
Claim 3
Dependent Claim
47 words
A thermal printing apparatus according to claim 1 , wherein said pair of transporting rollers comprise a driving roller and a driven roller, and wherein said shaft moving means moves said driven roller towards and away from said driving roller depending on the thickness of the medium.
Claim 4
Dependent Claim
49 words
A thermal printing apparatus according to claim 2 , wherein the driven roller is a cleaning roller disposed opposite the transporting rollers and makes a mating pair with at least one transporting roller and serves to remove dirt and foreign matter away from a printing surface of the medium.
Claim 5
Dependent Claim
44 words
A thermal printing apparatus according to claim 1 , further comprising head pressure adjusting means that adjusts a head pressure of said thermal head based on an operation of said shaft moving means that moves the shaft depending on the thickness of the medium.
Claim 6
Dependent Claim
21 words
A thermal printing apparatus according to claim 1 , wherein said shaft moving means moves the shaft relative to the medium.
Claim 7
Dependent Claim
23 words
A thermal printing apparatus according to claim 5 , wherein said shaft moving means moves the shaft toward and away from the medium.
Claim 8
Dependent Claim
22 words
A thermal printing apparatus according to claim 6 , wherein said shaft moving means moves the shaft perpendicular relative to the medium.
Claim 9
Dependent Claim
56 words
A thermal printing apparatus according to claim 1 , wherein the head angle member maintains the position of the thermal head at a non-zero angle relative to a plane in which the medium is transported when the thickness of the medium changes, by means of a shaft that is movable toward and away from the medium.
Claim 10
Dependent Claim
53 words
A thermal printing apparatus according to claim 8 , wherein the thermal head angle member maintains the thermal head at a right angle to a plane in which the medium is transported when the thickness of the medium changes, by means of the shaft which is movable toward and away from the medium.
