Abstract

PURPOSE:To manufacture the titled device, which can fix the movement of a slip on a printing on, the slip, by bringing a carrier near an end section, separating a slip hold-down arm from a guide plate and bringing the slip into contact with the guide plate by pressure by the slip hold-down arm on the printing. CONSTITUTION:The projecting secton 25 of a slip hold-down arm 20 is brought into contact with a guide plate 7 in a resilient manner by a spring, and mounted rotatably. When a carrier 6 is moved to the end section of a platen 2, pins 28 push an inclined plane 27 to turn the arm 20, and the projecting section 25 is separated from the guide plate 7. A slip 13 can be inserted toward a slip receiver 14. When the carrier 6 is moved for printing and the pins 28 are separated from the inclined plane 27, the slip holding arm 20 is rotated by the force of the spring, and the slip 13 is pushed against the guide plate 7 by the projecting section 25. The slip 13 does not move along the platen 2 even when it is contact with a dot pin at the nose of a printing head 5, and the slip can be printed distinctly.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a slip holding device for a printer at a register.

Technical background of the invention and its problems First, FIG. 1 shows a conventional example of a printer used for a register. A frame (1) holds a platen (2) and guide shafts (3) (4), and a carrier (6) holding a print head (5) can freely slide onto these guide shafts (3) (4). is held in The lower part of the guide plate (7) located on the front extended surface of the platen (2) faces another guide plate (8), and the receipt paper (9) is placed between these guide plates (7) and (8). ) and journal paper α0) are provided. still.

At the bottom of the platen (2), there is provided a slip holder α which supports the lower end of the slip α→. Furthermore, a stamp pad 0Q is attached to the mounting hole 0→ formed on both sides of the frame (1).
is a stamp α for stamping on the receipt paper (9).
The solenoid α that drives the motor is held.

Therefore, receipt paper (9) and journal paper αQ
The printing head (5) is held between two rollers (6) and is intermittently fed in the row direction while the carrier (6) is in operation.
) is printed.

Print in the same way when printing on slip Q1.

In the case of slip a→, since it is not held by the feed roller α force α■, when the print head (5) moves along the platen (2), it touches the print head (5) and moves.

Platen (2) as print head (5) as shown
If a dot printer head with a small gap between the dot printer head and the dot printer head is used, the slip Q3 has the disadvantage that it is more likely to move.

Purpose of the Invention The present invention has been made in view of the above points, and provides a slip holding device for a printer in a register that can fix the movement of the slip when printing on the slip.

SUMMARY OF THE INVENTION This invention brings a slip holding arm into elastic contact with a guide plate, positions a carrier at the end of a platen when printing on a slip, and at this time presses a slip holding arm provided on the carrier or print head. The slip holding arm is separated from the guide plate and the slip is inserted into the front of the platen, and the slip holding arm remains in place during the printing operation.

Embodiment of the Invention An embodiment of the invention will be described with reference to FIGS. 2 to 5. Components that are the same as those described in FIG. 1 are designated by the same reference numerals, and description thereof will be omitted. Bent pieces (one piece) are formed on both sides of the stamp pad 0Q, and slip holding arms (goods) are formed on these bent pieces α in the slip holding direction (
It is rotatably attached by a pin (c) while being biased in the counterclockwise direction. A protrusion (C) that contacts the guide plate (7) on the outside of the receipt paper (9) and journal paper 00 is formed on the bar (C) that connects the side piece (C) of the slip holding arm. The bending piece (C) that bends inward from the lower end of (C) is formed with a slope that approaches the platen (2) toward the center. And career (6)
A pair of left and right presser pins (A) are erected at the tip of the holder.

In such a configuration, the protrusion (c) of the slip holding arm (a) resiliently contacts the guide plate (7), but does not move the carrier (6) to one end or the other end of the platen (2). As the pin (c) pushes against the slope (goods) and gradually increases the pressure, the slip holding arm (a) rotates against the force of the spring Q■, and the protrusion (c) pushes against the guide plate (7). ) to move away from Therefore, the slip α1 can be inserted toward the slip receiver α→. The carrier (6) is moved for printing, but when the pin (goods) leaves the slope (b), the slip holding arm (a) is rotated by the force of the spring (c) and holds the protrusion (c). Press the slip α1 against the guide plate (7). Therefore, even if the slip α1 touches the dot pin at the tip of the print head (5), it will not move along the platen (2). This allows for clear printing.

In addition, if slip α→ is not used, the protrusion (c)
is located outside of the receipt paper (9) and journal paper αO, so even if the carrier (6) is positioned at any position, the receipt paper (9) and journal paper 01 can be sent between the protrusions (c). be able to. Therefore, the slip holding arm (1) does not get in the way and can be kept attached at all times.

Effects of the Invention Since the present invention is configured as described above, when printing using a slip, the carrier can be moved to the end and the slip can be pushed, and the tip arm can be moved away from the guide plate to set the slip. The slip holding arm can press the slip against the guide plate to fix the movement of the slip, and therefore has the effect of making clear printing possible.
