Abstract

PURPOSE:To effect any slip print while two types of slip sheets remains set by dividing a platen and a sheet feeding mechanism, bringing them into contact with each other, and independently driving platens by a changeover switch. CONSTITUTION:First and second platens 1, 2 are adjacently provided on the same line, the platen 1 is provided with a manual sheet feeding first regulating wheel 3 at the left side of a printer, and the platen 2 is provided with a manual sheet feeding second regulating wheel 4 at the right side of the printer. The platens 1, 2 are independently driven by a drive motor, and sheet feeding rollers capable of independently rotating are pressed on the backs of the platens. Accordingly, a first slip sheet 6 can be mounted on the platen 1, and a second slip sheet 7 can be mounted on the platen 2. Further, a wide sheet can be mounted over the platens 1 and 2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printer, and particularly to a roller-feed type printer that is connected to an information processing device and prints on different form sheets depending on output information.

[Conventional technology]

Conventionally, this type of printer performs printing by setting a predetermined form sheet according to output information.

[Problem to be solved by the invention]

The above-mentioned conventional printer has a drawback in that when printing on a different form paper from the previous form paper, it is necessary to set the form paper each time. Another disadvantage is that a plurality of dedicated printers must be installed in order to avoid the trouble of frequently replacing paper sheets.

[Means to solve the problem]

The printer of the present invention is a roller-feed type printer, and includes two platens of the same diameter that are arranged adjacent to each other on the same line and driven independently, and a paper-feed roller that is pressed against each of the two platens and rotates independently. and a changeover switch for specifying whether to drive either or both of the two platens, and a control unit that transmits the print type to the host computer and controls the printer drive unit according to the designation of the changeover switch. Consisted of.

〔Example〕

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

FIG. 1 is an external perspective view of one embodiment of the present invention, and FIG. 2 is a block diagram of the control section of FIG. 1. In FIG. 1, a first platen 1 and a second platen 2 are provided adjacently on the same line, and the first platen 1 is provided with a first adjustment wheel 3 for manually feeding paper on the left side of the printer, The second platen 2 is provided with a second adjustment wheel 4 for manually feeding paper on the right side of the printer. Further, the first platen 1 and the second platen 2 are each driven independently by a drive motor (not shown), and a paper feeding roller that can rotate independently is crimped onto the back of each platen. There is. Therefore, the first form paper 6 can be mounted on the first platen 1, and the second form paper 7 can be mounted on the second platen 2, and furthermore, the first form paper 6 can be mounted on the first platen 1 and the second form paper 7 can be mounted on the second platen 2. It can also be installed.

A changeover switch 5 provided on the side of the printer is a switch for driving either the first platen 1 or the second platen 2, or both platens, as shown in FIG. Each designation is given to the printer control circuit 11. The printer control circuit 11 transmits the printing format to the host computer according to this designation, and provides a driving signal to the printer driving section.

〔Effect of the invention〕

As explained above, in the present invention, the platen and the paper feed mechanism are separated and brought into close contact with each other, and each platen is driven independently by a changeover switch, so that printing of any form can be performed while two types of form paper are set. This has the effect of avoiding the trouble of resetting two types of form paper for each type of form, and allowing processing to be performed with one printer. Furthermore, since both platens can be driven simultaneously, it is possible to use the printer for wide paper sheets.

Claims (1)

[Claims] In a roller feed type printer, two platens of the same diameter are arranged adjacent to each other on the same line and driven independently, a paper feed roller is pressed onto each of these two platens and rotates independently, and the two platens are driven independently. 1. A printer comprising: a changeover switch for specifying whether to drive either or both of the changeover switches; and a control section that transmits a print type to a host computer according to the designation of the changeover switch and controls the printer drive section.
