JPH0493272A - Mechanism for changing over a plurality of continuous forms in printer - Google Patents

Abstract

PURPOSE:To easily conduct a form change-over in performing a plural types of work by a method wherein one is selected out of a plurality of preset continuous forms only by an instruction from a user, and a printable state is automatically made. CONSTITUTION:With the input of a change-over instruction, a lift mechanism 17 is moved upward, and a connection support mechanism 2 is connected to a change-over drive mechanism 13. On the other hand, during a normal printing, a tractor drive transmission mechanism 14 is connected to a tractor drive mechanism 15, whereby a drive force is transmitted to a tractor in to feed a form. However, during a form change-over, said mechanisms are separated from each other. At the time of a form change-over, the connection support mechanism 2 is moved in parallel by the rotation of the change-over drive mechanism 13 until a predetermined position is detected by a position detecting mechanism 16. Then, the lift mechanism 17 is moved downward, and the connection support mechanism 2 and the change-over drive mechanism 13 are separated from each other. A tractor drive transmission mechanism 14 of a newly selected tractor 1n is connected to the tractor drive mechanism 15, and a new form can be printed.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to form printing by a printer, and more particularly to a multiple continuous form switching mechanism for a printer that switches between unique forms in a plurality of specific tasks without user intervention. .

[Conventional technology]

Conventionally, this type of printer has been able to hold only one type of form at all times, and if the form differs depending on a specific job, the form has to be changed manually using an operator.

[Problem to be solved by the invention]

The above-mentioned continuous printing of multiple forms by the conventional printer requires manual switching of forms by an operator depending on each specific job, which has the disadvantage of complicating and delaying the work.

SUMMARY OF THE INVENTION In view of the above-mentioned points, an object of the present invention is to provide a plurality of consecutive forms switching mechanism for a printer, which allows a plurality of forms to be centrally managed and operated on the printer side without any special operation by an operator.

[Means to solve the problem]

The multiple continuous form switching machine of the printer of the present invention includes a paper feeding tractor that supplies continuous forms, a paper feeding mechanism including a platen and a sheet guide that transports the continuous forms, and a continuous form that is transferred to the paper feeding mechanism. A printer comprising a print head that prints on a plurality of continuous slips, and a connecting support that supports a plurality of paper feeding tractors corresponding to each of the plurality of types of continuous slips and switches for each of the continuous slips to prepare for supplying a specified continuous slip. and a cutter that cuts the continuous slips before switching the continuous slips.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is an explanatory blade showing the configuration of an embodiment of the present invention.

The printer that implements the multiple continuous switching mechanism of this example is as follows:
A tractor 1n that holds the form, a continuous support mechanism 2 that switches the tractor arbitrarily, a cutter 3 that cuts the form, a platen 4 that sends the form, a sheet guide 5 that eliminates the curling of the form, and a veil that presses the form against the platen. roller 6
, a sheet guide 7 that correctly feeds the form for printing, a print head 8 that prints characters on the form, a sheet guide 9 that supports the pressure of the head, a guide roller 10 that feeds the form, and a sheet guide 11 that correctly feeds the form when switching. It consists of

Further, referring to FIG. 2, it is a schematic diagram of a mechanism for switching the tractor according to the target form. This mechanism consists of a tractor 1n that holds paper, a continuous support mechanism 2 that supports and switches multiple tractors, a switching drive mechanism 13 that drives the continuous support mechanism when switching, and a tractor that transmits driving force to the tractor during printing. A drive transmission mechanism 14, a tractor drive mechanism 5 that provides tractor drive power, and a position detection mechanism 16 that detects the position of the tractor when switching between tractors.
and an elevating mechanism 17 that performs elevating, lowering, and supporting during switching.

All the forms to be used are set in each tractor in advance, and the position of the tractor corresponds to the type of the set forms.According to the user's instructions, the tractor 1n holding any form can be set. The document is moved to a specified printing position, and the document is sent to the printing section by the tractor 1n to enable printing.

The form switching mechanism will be explained with reference to FIG. 2. When a switching instruction is input, the elevator mechanism 17 is raised, and the continuous instruction mechanism 2 and the switching drive mechanism 3 are connected. on the other hand,
In the tractor 1n, during normal printing, the tractor drive transmission mechanism 14 and the tractor drive machine $1115 are connected to transmit driving force to the tractor 1n, and the form is sent, but when the form is switched, they are separated. At the time of document switching, the continuous support mechanism 2 moves in parallel due to the rotation of the switching drive mechanism 13, and when a predetermined position is detected by the position/side ratio mechanism 16, the movement stops, the elevating mechanism 17 descends, and the connection support mechanism 2
and the switching drive mechanism 13 are separated. Then, the tractor drive transmission mechanism 14 of the newly selected tractor 1n,
It is connected to the tractor drive mechanism 15 and can be printed as a new form.

To explain the movement of the form at the time of switching with reference to Figure 1,
At the time of switching, the paper is fed to a predetermined position, and the cutter 3 cuts the form at the predetermined position. The cut form is discharged by driving the platen 4 and the kite roller 10.

When the ejection is completed, the bail roller 6, print head 8, and force roller 10 are evacuated in preparation for the next set of forms.On the other hand, the forms left on the tractor side are fed in the opposite direction to a predetermined position. Make sure that there are no obstacles at the time of switching.When the tractor switching is completed, the tractor 1n feeds the paper and it is sent along the sheet guide 15.The bail roller 6, print head 8, and The guide roller 10 is set in a printable state.

〔Effect of the invention〕

As explained above, the present invention selects a plurality of pre-loaded continuous forms simply by instructions from the user,
By automatically setting the printable state, it is possible to easily switch between forms for multiple tasks.
