Embodiment Construction

[0033] Hereinafter, embodiments of a variable web printer to which the present invention is applied will be described with reference to the drawings.

[0034] (whole composition)

[0035] figure 1 is a perspective view showing the internal structure of the variable web printer according to this embodiment, figure 2 is an explanatory diagram showing a part of the transmission mechanism, image 3 It is a schematic cross-sectional view of the conveying mechanism partially cut by a vertical plane including the axis of the paper feed shaft, Figure 4 It is a partial rear perspective view in a state in which a part of the conveyance mechanism part is omitted.

[0036] Referring to these figures, the variable paper width printer 1 has a metal printer body frame 2, and a conveying mechanism 4 for conveying perforated paper 3 is assembled at the front end side of the printer body frame 2. The position on the side is assembled with a printing mechanism 5 for printing on the conveye...

Abstract

The invention provides a paper width variable printer, which can correspond to perforated paper of various widths. In the variable paper width printer (1), among the left and right sprockets for conveying the perforated paper (3), one is set as a moving side sprocket (9) that can move closer to and farther away from the other, The upper paper guide (15) is connected to the moving side sprocket (9), and the upper paper guide (15) is installed on the side of the press plate (17) of the main frame (2) of the printer. On the horizontal plate portion (17b), this upper paper guide (15) is locked by a locking mechanism (50). Unlock the locking mechanism (50), slide the upper paper guide (15) along the width direction of the printer, and slide the moving side sprocket (9) and the side paper guide (19) connected thereto , it can be moved to a position corresponding to the format of the perforated paper 3 .

Description

technical field [0001] The invention relates to a printer for printing on perforated paper, in particular to a variable paper width printer capable of printing on perforated paper of different widths with variable sprocket wheel for conveying perforated paper. Background technique [0002] As a printer, a form of printing on perforated paper with perforations formed at regular intervals along both edges is known. This type of printer has a pair of left and right sprockets for conveying punched paper, and the sprockets formed on the outer peripheral surfaces of these wheels are fitted into the left and right toothed holes of the punched paper to mount the punched paper. Therefore, printing cannot be performed using perforated paper having a width other than the perforation interval corresponding to the sprocket pitch. [0003] However, the specifications of perforated paper generally used are 76.2 mm (3 inches) and 88.9 mm (3.5 inches). In order to be able to use these two ...
