Description

[Detailed Description of the Invention] The present invention relates to a journal and continuous form processing mechanism that is capable of printing and transporting only continuous forms set over journal paper to the same platen.

2. Description of the Related Art Conventionally, printing devices have been generally used that print by setting journal paper or continuous forms on the same platen. In this case, it is possible to print by setting the journal paper or continuous form alone, but once the journal paper has been set, it is possible to set the continuous form on top of it without removing it and print on this continuous form. This was difficult because it caused the journal paper to move around.

This invention is intended to solve the above problems.
It is an object of the present invention to provide a journal and continuous form processing mechanism that enables printing on continuous forms stacked on journal paper.

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

Fig. 1 is a front view showing an overview of the journal and continuous form processing mechanism according to the present invention, and Fig. 2 is a detailed view of the same main parts. In the figure, 1 is a platen, 2 is a supply shaft, 3 is a take-up shaft, 4 is a tractor,
5 is the feed roller, 6 is the push plate, 7
is a brake retainer, and 8 is a solenoid.

A feed roller 5 is provided along the journal paper path between the platen 1 and the supply shaft 2.

The push plate 6 is swingably provided opposite the feed roller 5 across the journal paper path, and is pressed against the feed roller 5 by a spring (not shown).

The brake holder 7 is swingably supported by the support shaft of the feed roller 5, and has a brake member 9 attached to its tip. This brake holder 7 is connected to a solenoid 8 via a connecting member 10.

A pulley 11 provided on the drive shaft of the tractor 4,
12, and a pulley 13 coaxial with the feed roller 5.
A belt 15 is passed around the idle pulley 14 and a pulley 16 coaxial with the feed roller 5.
and pulley 1 fixed to take-up shaft 3
7 and a belt 18 is passed between them. That is, the feed roller 5 is driven by the drive shaft of the tractor 4 via the belt 15, and the take-up shaft 3 is driven by the drive shaft of the tractor 4 via the belt 15.
5, it is adapted to be driven via a feed roller 5 and a belt 18.

The journal paper 30 is wound around a supply shaft 2, and is fed out from the supply shaft 2 through a feed roller 5 and a push plate 6.
The continuous form 40 is taken up by the take-up shaft 3 via the platen 1, fed out between the guide plates 19 and 20, passed between the push plate 6 and the guide plate 20, passed through the platen 1, and transported by the tractor 4. Ru.

When setting the journal paper 30 or the continuous form 40 alone for printing, the solenoid 8 is not activated and the push plate 6 and brake holder 7 are
is located at the solid line in FIG. In this case, the journal paper 30 is fed out by the feed roller 5 driven by the drive shaft of the tractor 4, and is taken up by the take-up shaft 3 driven by the drive shaft, and the continuous form 40 is transported by the tractor 4, Continuous printing is possible for each.

When the continuous form 40 is set on top of the journal paper 30 as shown in the figure and the continuous form 40 is to be printed, the solenoid 8 is activated. When the solenoid 8 is actuated, the brake holder 7 is driven by the solenoid 8 via the connecting member 10 which is moved in the direction of the arrow in FIG.
Rotating counterclockwise in the figure, the brake member 9 presses the push plate 6 through the journal paper 30, swinging the push plate 6 to the position indicated by the chain line in FIG. In this state, journal paper 30
As it separates from the feed roller 5, it is pressed by the push plate 6 and the brake member 9 and braked. Note that the supply shaft 2 is formed in a driven type and rotates only when the journal paper 30 is fed out, but if the brake member 9 applies the brake, the journal paper 30 is not fed out and the supply shaft 2 does not rotate. When the continuous form 40 is transported (line feed, ejected, etc.) by the tractor 4 in this state, since the journal paper 30 is braked as described above, the belt 18 slips and causes the journal paper 30 to slip.
0 is not wound up, and the journal paper 30 is not rotated with the continuous form 40.

As described above, according to the present invention, when printing continuous forms by stacking them on journal paper, the brake member is advanced by a solenoid, etc., and the push plate is separated from the feed roller while the journal paper is being printed. Since the brake member and the push plate apply pressure to the journal paper, the journal paper does not move when transferring the continuous forms that have been printed, and printing on the continuous forms can be performed smoothly. is possible.

[Brief explanation of the drawing]

Fig. 1 is a front view showing an overview of an embodiment of the journal and continuous form processing mechanism according to the present invention, and Fig. 2 is a detailed view of the same main parts, in which 1 is a platen, 2 is a supply shaft, and 3 is a take-up. 4 is a tractor (transfer means), 5 is a feed roller, 6 is a push plate, 7 is a brake holder, 8 is a solenoid, 9 is a brake member, 15 and 18 are belts, 30 is journal paper, 40 is a continuous It is a form.

Claims (1)

[Scope of utility model registration request] In a journal and continuous form processing mechanism that processes journal paper that is fed onto a platen from a supply shaft and wound onto a take-up shaft after printing is completed, and continuous forms that are fed out onto the platen and transferred by a transfer means after printing is completed. , between the supply shaft and the platen, a feed roller and a push plate which is in pressure contact with the feed roller via a journal paper and is movable in a direction away from the feed roller are provided to face each other, and the take-up shaft is connected to the transfer means. The drive shaft is configured to be driven by a belt through the feed roller, and a brake member that faces the push plate and the journal paper and can move forward and backward is provided to print continuous forms set overlappingly on the journal paper. A journal, characterized in that when performing this, the brake member is moved forward to sandwich and press the journal paper between the brake and the push plate, and at the same time displace the push plate in a direction away from the feed roller. Continuous form processing mechanism.
