Abstract

PURPOSE:To attractively and cleanly cut the cut end of the paper by providing a holder holding a cutter edge and slid along the opening of a bracket and a spring exciting the cutter edge put in contact with the paper to the paper side. CONSTITUTION:When the paper is to be cut, the knob section 4e of a holder 4 is pushed down, and a cap 4d is thrust to a sliding member 5. A cutter edge 10 is brought into contact with the paper on a lower paper guide 2 and set at the cutting position. The pressure with the proper value for cutting is applied to the cutter edge 10 by a spring 7. When the holder 4 is moved under this condition, the sliding member 5 is slid on a bracket 3, the support shaft 4c of the holder 4 passes an opening 3a, the cutter edge 10 is moved while being kept in contact and thrust to the paper, thereby the paper is cut.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a manual cutter for a paper delivery device, and more particularly to a manual cutter used in a paper delivery device such as a facsimile machine and similar devices.

[Prior Art] Conventionally, facsimile machines and similar devices used as paper sending devices have been equipped with a manual cutter for manually cutting the paper being sent out. This manual cutter has a part with a saw blade attached along the lJ force direction of the paper to be delivered,
The delivered paper was turned over and brought into contact with this saw blade to cut the paper.

[Problems to be Solved by the Invention] However, with the above-mentioned conventional manual cutter, the cutting is done by hand using a part with a saw blade, so the cut ends inevitably have a saw blade shape, resulting in poor appearance. There is a drawback that cutting errors are likely to occur.

Therefore, an object of the present invention is to make it possible to cut paper reliably and with good appearance.

[Means for Solving the Problems] The technical means of the present invention to solve such problems is that in a manual cutter for a paper feeding device that is installed in a paper feeding device and cuts the paper to be fed out, A pair of upper and lower plate-shaped paper guides that form a path for paper to pass through, a bracket provided on the upper paper guide and having an opening along the width direction of the paper, and a cutter blade that comes into contact with the paper on the lower paper guide. The apparatus includes a holder that holds the cutter blade and slides along the opening of the bracket, and a spring that biases the cutter blade in contact with the paper toward the desk.

[Embodiment] Hereinafter, a manual cutter for a paper feeding device according to an embodiment of the present invention will be described based on the accompanying drawings.

As shown in FIGS. 1 to 3, the manual cutter according to the embodiment is attached to a paper feeding device such as a facsimile machine or a similar device. This includes a pair of upper and lower plate-shaped paper guides 1 and 2 that form a path through which the paper sent from the paper feeding device passes. The upper paper guide 1 has an opening 1a formed along the 111 direction of the paper (direction perpendicular to the feeding direction). Further, a bracket 3 having a substantially U-shaped cross section is fixed to the upper paper guide 1 so as to straddle the opening 1a. In the earthen wall of the bracket 3, a long hole-shaped opening 3a extending in the [11] direction of the paper is opened, corresponding to the opening 1a.

Furthermore, in the opening la of the upper paper guide)<1, there is a cutting position A (a second
(Fig. 1) and separation position B (Fig. 1) where the paper is moved back and away from the paper.
A cutter blade 10 that can be moved to two positions is provided. This cutter blade lO is connected to the opening 3a of the bracket 3.
The cutter blade 10 is held in a holding body 4 inserted through the cutter blade 10 so as to be able to move forward and backward. The holder 4 includes a fixed plate 4a to which the cutter blade 10 is fixed, a support plate 4b that supports the fixed plate 4a via a spring 7, and a support that supports the support plate 4b and is inserted into the opening 3a. A shaft 4c, a cap portion 4d crowned on the upper end of the support shaft 4c, and a U-shaped knob portion 4 protruding from the cap portion 4d.
It is composed of e. In addition, the fixed plate 4a and the support plate 4
At the cutting position A where the cutter blade 10 is in contact with the paper, the spring 7 between the cutter blade 10 and the cutter blade 10b urges the cutter blade 10 toward the desk side and provides the necessary pressing force for cutting.

Further, on the bracket 3, there is a support shaft 4c of the holder 4.
A sliding member 5 is provided through which the holding body 4 is slid along the opening 3a.

Furthermore, a splinter is provided between the sliding member 5 and the cap portion 4d of the holding body 4 to support the holding body 4 with respect to the sliding member 5 and to urge the cutter blade 10 to the above-mentioned separated position fiB. 6 is interposed.

Therefore, according to the manual cutter for a paper feeding device according to this embodiment, the holding body 4 is normally lifted upward by the urging force of the splinter 6, as shown in FIG. is set at M open position B.

Next, when cutting paper, as shown in FIG. 2, the grip part 4e of the holder 4 is pushed down and the cap part 4d is brought into contact with the sliding member 5. As a result, the cutter blade 10 comes into contact with the paper on the lower paper guide and is set at the cutting position A. At this time, the spring 7 applies pressure to the cutter blade 10 at an appropriate value for cutting.

When the holder 4 is moved in the direction of the arrow in FIG. 3 in this state, the sliding member 5 slides on the bracket 3 and the support shaft 4c of the holder 4 passes through the opening 3a, so that the cutter blade 10 It moves while being pressed against the paper, and as a result, the paper is cut. In this case, since the paper is cut by the cutter blade 10, the cut end looks good, and since the paper is pressed against the lower paper guide 2 and does not move, cutting errors are prevented.

When cutting is completed and the grip portion 4e of the holding body 4 is released to make it free, the cutter blade lO is pushed up via the holding body 4 by the biasing force of the spring 6 and separated from the lower vapor guide 2. As a result, the paper is separated and taken out.

[Effects of the Invention] As explained above, according to the manual cutter for a paper feeding device of the present invention, cutting can be performed by moving the cutter blade while holding it with a spring biased against the holder, so it is easy to see the cut end of the paper. The paper can be cut neatly and beautifully, and since the paper is pressed against the lower vapor guide and does not move, it has the effect of preventing cutting errors.
