Abstract: A printer having an opening provided on an accommodating portion for a recording rolled paper, wherein the opening is covered by first and second swing covers which pivot in opposite directions when moving from a closed position in which they are relatively close to each other. The first swing cover has a first guide member, and the second swing cover has a second guide member. After loading the recording rolled paper into the accommodating portion, the first swing cover is firstly closed. Then, the second swing cover is closed so that the label sheet is automatically arranged to curve by passing around the first guide member and the second guide member.

Abstract: A printer having an opening (6) provided on an accommodating portion (4) for a recording rolled paper, wherein the opening (6) is covered by first and second swing covers (11) and (12) which pivot in opposite directions when moving from a closed position in which they are relatively close to each other. The first swing cover (11) has a first guide member (31), and the second swing cover (12) has a second guide member (32). After loading the recording rolled paper (3) into the accommodating portion (4), the first swing cover (11) is firstly closed.

Abstract: A thermal printer for printing on a recording medium adapted to travel along a path through the thermal printer includes a frame and a thermal print head supported by the frame, the thermal print head carrying printing elements. A cover hinged to the frame is movable between an open position and a closed position. An elastomeric platen roller is rotatably supported by the cover, the thermal print head and the platen roller being relatively resiliently biased toward each other to urge the printing elements carried by the thermal print head into contact with a recording medium disposed between the thermal print head and the platen roller when the cover is in the closed position.

Abstract: A paper termination detecting apparatus for detecting an amount of a paper roll that is below a predetermined amount of paper, having: a detecting lever including a detecting piece being movable within a space of a core part of the paper roll, and a protruding piece spaced a predetermined distance apart from the detecting piece, the protruding piece being allowed to come in contact with a side of the paper roll; and a detecting switch for converting a motion of the detecting lever into an electrical signal when the detecting piece moves into the space of the core part of the paper roll.

Abstract: A printer comprising a cutting device for cutting the recording paper with a clean, straight edge is achieved. The printer comprises a pair of separable cutting blades, a fixed blade 14 and a movable blade 9, disposed with the cutting edges thereof mutually opposed in a substantially facing relationship on opposite sides of the paper exit 15 from which the recording paper is ejected. The movable blade 9 contacts fixed blade 14 at a point, and is driven with a scissors-like sliding action across fixed blade 14 by means of movable blade drive 10. Fixed blade 14 is supported on an openable cover frame 8 by support member 16 with a certain amount of play. Movable blade 9 is housed inside cutter unit frame 11. The cover frame supporting the fixed blade can be displaced between a cutting position wherein the fixed blade and the movable blade are disposed in an adjacent, substantially facing relationship and a non-cutting position wherein the fixed blade and movable blade are disposed at a distance from one another.

Abstract: A thermal line printer includes a frame. The head holding member is rotatably mounted on the frame and holds a thermal head therein. The thermal head holding member is biased towards the platen by a spring. A first level cooperates with a head holding member to separate the thermal head from the platen. A second lever member cooperates with an auxiliary member to rotate the auxiliary member through a large angle. The head holding member engages the auxiliary member and further rotates through a large angle to move the thermal head further away from the platen.
