Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper cutter mechanism in a printer device.

Conventionally, the paper cutter mechanism of printer devices has been installed near the printing section in the frame, and each time the paper is set to remove the paper, the paper must be set through the paper cutter mechanism, and the paper The replacement operation was complicated.

The present invention has been made to solve these problems, and an object of the present invention is to provide a paper tension mechanism that has a simple mechanism and facilitates paper exchange operations.

Embodiments of the invention will be described below with reference to the drawings.

1 and 2 schematically show the printer device, in which 1 is a printer section, 2 is a keyboard section, 3 is a frame,
Reference numeral 4 denotes a lid, and the lid 4 is provided so as to be openable and closable with respect to the frame for purposes such as paper exchange.

As shown in detail in FIG. 3, the lid 4 is integrally formed with a paper tension vine portion 5, and the rotation center shaft 6 integrally provided with the lid 4 is connected to a rectangular support fitting 7 provided on the frame. Since it is movably engaged with the mating hole 8 and the rotation center shaft 6 is biased in the direction of arrow A by a spring 9 whose one end is fixed to the frame, the roller 10 provided at the rear end of the lid 4 is pressed into engagement with an inclined stopper 11 provided on the frame and moved upward along the inclined stopper 11, so that the rotation center shaft 6 is engaged with the upper right end of the play hole 8 of the support fitting 7 as shown in the figure. While being held, the inner front end of the lid 4 engages with a stopper 12 provided on the frame, and the lid 4 is locked in a closed state with respect to the frame.

When the lid 4 is in the closed state, the paper tension vine portion 5 and the frame 3
By creating a gap a between the stay 13 and the stay 13 provided inside the platen 1 of the printer section, the printing paper 15 sent by the rotation of the pin feed wheel 140 is
6 and the head 17, and can be led to the upper surface of the frame through the gap a.

18 is a roll of printing paper.

When cutting the printing paper 15, lightly press the lid 4 in the direction of arrow B to push down the paper force vine portion 5 against the bias of the spring 9 to press it against the printing paper 15, and then push it out onto the top surface of the frame by hand. It can be easily cut by pulling the printed paper.

Further, since the lid 4 is locked to the frame by the spring 9, the support fitting 7, the stopper 12, the tilt stopper 11, etc., the lid 4 will not open even if the printer is tilted when the printer is carried. There isn't.

When replacing paper, use a force slightly stronger than the tension of spring 9 to close lid 4.
By rotating the front end of the paper in the direction of arrow C, the lid 4 can be opened easily around the central axis of rotation 6. At this time, the paper clipping section also moves together with the lid 4, so the paper clipping section will not become an obstacle. Paper can be easily replaced without any problems.

[Brief explanation of the drawing]

The figures show an embodiment of the paper force vine mechanism in a printer device according to the present invention. FIG. 1 is a plan view of the entire printer device, FIG. 2 is a side view thereof, and FIG. 3 is a front view of main parts. be. In the figure, 3 is a frame, 4 is a lid, 5 is a paper tension vine part, 6 is a rotation center axis, 7 is a support bracket, 8 is a square play hole, 9 is a spring, 10 is a roller, 11 is an inclined stopper, 12 1 is a stopper, 13 is a stay, and 15 is printing paper.

Claims (1)

[Claims] 1. In a printer device having a lid that can be opened and closed with respect to a frame, a rotation center shaft is integrally provided at the rear end of the lid, and the rotation center shaft can be moved into a rectangular play hole of a support fitting provided on the frame. A roller is provided at the rear end of the lid, and a spring is provided between the frame and the rotation center shaft to bias the rotation center rearward; A stopper engages with the inner side of the front end of the biased lid to lock the lid in the closed state, and a stopper engages with the front roller biased by the spring so that the central axis of rotation moves the roller into the loose position. an inclined stopper that moves upward until it engages with the rear upper end of the hole;
A stay is provided along the lower side of the print-completed paper path, and the lid is further provided with a stay that faces the stay and the print-completed paper path and presses the lid downward to move it against the biasing force of the spring. 1. A paper cutter mechanism in a printer device, characterized in that a paper cutter portion is provided which presses the paper against the stay when the paper is pressed against the stay.
