Description

DETAILED DESCRIPTION OF THE INVENTION [Outline] The present invention is a printer in which a casing is supported so that a single-cut guide is positioned at a horizontal position and an inclined position. The purpose is to enable setting, and an inverted V-shaped groove cam is provided on the housing side, and the groove cam allows positioning of the single-cut guide at each position to achieve the purpose.

[Industrial application field]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer provided with a cut sheet guide positioned at a horizontal position and an inclined position, and more particularly to a support mechanism for the cut sheet guide.

In this type of printer, the single-cut guide is supported by the housing, and when using the continuous form, the paper that is positioned in the horizontal position and that is fed into the printer is separated from the paper that is ejected from the printer to guide the cut-sheet use. At times, they are positioned at inclined positions and play the role of guiding the single form.

[Conventional technology]

FIG. 4 shows a conventional printer which is equipped with such a cut sheet guide and which is also used for continuous printing.

In FIG. 4, 1 is a single-cut guide, and the single-cut guide is
It is rotatably supported by the housing 2 of the printer with a base as a fulcrum, and is positioned at an illustrated inclined position for guiding a single-cut sheet and a horizontal position for guiding a continuous ledger. In the horizontal position, the cut-sheet guide 1 is locked and positioned on the housing 2 to guide the continuous ledger. That is, the single-cut guide 1 in this state
Separates and guides a sheet that is supplied from the outside through the lower side of the cut sheet guide 1 toward the printing portion on the platen and a sheet that is discharged after passing the upper side of the cut sheet guide 1 after printing. Further, during the processing of the single-cut, the single-cut guide 1 positioned at the inclined position plays a role of a guide when setting the single-cut, and also a role of holding the single-cut printed with line feed in a state where the print content is easy to see. Fulfill As a means for supporting the single-cut guide 1 at an inclined position, conventionally, as shown in FIG. 5, a hook 3 having elasticity is provided on the housing side, and the single-cut guide 1 is shown by a solid line in FIG. It is adapted to be engaged with the hook 3 and supported in an inclined position. When it is desired to position the single-cut guide 1 at the horizontal position as shown by the chain line in FIG. 5 during the continuous book processing, the hook 3 is detached from the single-cut guide 1 by utilizing its elasticity, and the single-cut guide 1 is moved backward. Can be rotated toward the horizontal position.

[Problems to be solved by the invention]

However, in such a conventional support mechanism for a single-cut guide, if the single-cut guide is pushed backward when setting the single-cut, the single-cut guide may fall backward.

[Means for solving problems]

The present invention provides a support mechanism for a single-cut guide that can solve the above problems, and FIG. 1 is a principle diagram thereof.

In FIG. 1, 11 is a cut sheet guide, and 15 is a printer casing.

First and second pins 13 and 14 are projectingly provided on both side surfaces of the base of the single-cut guide 11.

The housing 15 is provided with an inverted V-shaped groove cam 12 that engages with the first and second pins 13 and 14, respectively, at a position facing each side surface of the cut sheet guide 11.

The inverted V-shaped groove cam 12 has the first and second pins 13, so that the single-cut guide 11 is positioned at the inclined position (second position) shown by the solid line in FIG.
A first pin 13 in a first groove 16 that engages 14
Second groove for engaging the bottom of the groove 16 and engaging the second pin 14 with the bottom to position the single-cut guide 11 at the horizontal position (first position) indicated by the diagonal lines in FIG. 17 is connected in an inverted V shape.

[Action]

The single-cut guide 11 is in a horizontal position when the first and second pins 13 and 14 engage with the first and second grooves 16 and 17, and the first and second pins 13 and 14 are first. By engaging with the groove 16 of each of them, they are surely supported in the inclined position.

Therefore, even if the cut-sheet guide 11 supported at the inclined position is pushed, it does not fall backward. Further, since the cut sheet guide 11 is positioned at the horizontal position by the engagement of the pins 13 and 14 and the grooves 16 and 17, no special means for locking the cut sheet guide at the horizontal position is required.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3.

FIG. 2 is a perspective view showing a support mechanism for a single-cut guide according to the present invention, in which 11 is a single-cut guide and 12 is an inverted V-shaped groove cam.

The single-cut guide 11 includes a first pin 13 and a second pin 14 that project from both side surfaces of the base.

The inverted V-shaped groove cams 12 are respectively formed at positions opposite to both side surfaces of the single-cut sheet guide 11 of the printer housing 15, and connect the first groove 16 and the second groove 17 in an inverted V-shape. Is configured.

The outline of the configuration of the present invention is as described above. Next, its operation will be described.

The first groove 16 is engageable with the pins 13, 14 and is shown in FIG.
As shown in (a), when the pins 13 and 14 are engaged with the groove 16, the single-cut sheet guide 11 is securely held at the inclined position (second position). Therefore, even if the single-cut guide 11 is pushed in this state when setting the single-cut, the single-cut guide 11 does not fall backward.

Also, the bottom portions 16a, 17a of the first and second grooves 16, 17 are
Has a spacing similar to the spacing of pins 13 and 14,
As shown in FIG. 3 (b), the pins 13 and 14 are provided with grooves 16 and
In the state of being engaged with the bottom portions 16a and 17a of the sheet, the cut sheet guide 11 is reliably held at the horizontal position (first position).

[Effect of device]

Since the present invention has the above-mentioned configuration and operation, it is possible to achieve the following various excellent effects.

(1) Since the single-cut guide is securely held in the inclined position by the engagement of each pin and the first groove, it is possible to eliminate the backward tilt of the single-cut guide, which has been a problem in the past. You can

(2) With the first pin engaged with the first groove and the second pin engaged with the second groove, the cut-sheet guide is positioned at a horizontal position. No special means for positioning the guide in a horizontal position is required.
