Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for separating a desired portion of a record carrier from a series of record carriers sent out from a record carrier such as a desktop calculator, a data collection device, or a character image printing device. This invention relates to a record carrier cutting device.

Conventionally, as a means for separating a desired portion of record carriers from a series of record carriers sent out from a recording device, as shown in FIG. 2,
A method is known in which the cutting edge of one blade 3 is applied as shown by the dotted line 2' and cut.

However, if the angle θ between the blade 3 and the portion of the record carrier 2 that protrudes from the blade 3 when separating the record carrier 2 is increased, the record carrier 2 may not be able to be cut off. The cut end cannot be pulled straight.

Therefore, when separating the record carrier 2, if the angle θ between the part of the record carrier 2 protruding from the blade 3 and the blade 3 is made smaller, and the record carrier 2 is pulled,
The record carrier 2 can be easily cut off, but if the angle θ is made small, the directions in which the record carrier 2 can be cut off are limited, and the attachment position of the blade 3 to the recording device is restricted, so it is difficult to design the recording device. There was a problem that the degree of freedom of

Furthermore, since the fulcrum of the record carrier 2 when the record carrier 2 is pulled off is the platen 1, the force when the record carrier 2 is cut off is directly transmitted to the record carrier holding mechanism such as the platen 1, and the force is directly transmitted to the record carrier holding mechanism such as the platen 1. There was a problem with negative effects.

The present invention has been made in view of such problems, and embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 2 is a block diagram of an embodiment of the present invention, and FIG. 3 is a perspective view of a recording device equipped with an embodiment of the present invention. The same reference numerals as those in FIG. 1 indicate the same parts. 4 is a first blade having a blade formed at its tip for separating the record carrier 2; and 5 is a second blade having a blade formed at its tip for separating the record carrier 2. , first blade 4
The second blade 5 is inserted into the discharge port of the record carrier 2 of the recording device in such a way that the tip of the first blade 4, which is submerged under the second blade 5, is close to the lower surface of the second blade 5. It is set in.

In this embodiment configured as described above, the record carrier 2 on which characters, images, etc. are formed is transferred from the platen 1 to the space between the first blade 4 and the second blade 5 of the recording apparatus. sent outside.

Therefore, when the part of the record carrier 2 on which desired characters, images, etc. are formed is separated from the series of record carriers 2 by the second blade 5, the record carrier 2 is brought into contact with the cutting edge of the second blade 5. When pulled, the record carrier 2 is cut straight along the cutting edge of the second blade 5.

By the way, when the record carrier 2 is cut by applying it to the second blade 5, the record carrier 2 cannot be separated unless the record carrier 2 is bent by the second blade 5 by a certain angle or more. However,
The record carrier 2 is delivered by the guide member 4 in close proximity to the second blade 5, and the record carrier 2
When the record carrier 2 is separated, the second
The part of the record carrier 2 that protrudes upward from the blade 5 of
In other words, bend slightly to the left in the figure.
Even if the record carrier 2 is pulled up vertically in the figure,
The angle required to separate platens 1 and 2 is
This can always be obtained regardless of the mutual positional relationship with the blade 5.

Incidentally, since the first blade 4 is also formed with a blade for separating the record carrier 2, the first blade 4
can also be used like a conventional blade 3 (see FIG. 1) to separate the record carrier 2.

Furthermore, the shapes of the cutting edges of the first blade 4 and the second blade 5 may be serrated blades as shown in FIG. 4 instead of straight blades as shown in FIG. 3.

(Effects of the Invention) As explained above, according to the present invention, as shown in FIGS. 2 and 3, when the angle between the first blade and the second blade is large, the blade Since the part of the record carrier that protrudes upward can be separated by either the first blade or the second blade, the area in which the record carrier can be separated is very wide, and it can be cut in any direction. You will be able to perform the separation operation even from the front. As a result, the attachment position of the blade to the recording device becomes free, and there is an effect that the degree of freedom in designing the recording device can be increased.

Furthermore, even when separating the record carrier using only the second blade, simply pulling up the record carrier can separate the record carrier regardless of the positional relationship between the platen and the second blade.
Since the angle necessary for separating the record carrier is always obtained between the blade of the second blade and the record carrier, the record carrier can be easily separated from any direction. This has the effect of increasing the degree of freedom.

Furthermore, when separating the record carrier with the second blade, the fulcrum of the record carrier is the first blade, so the force when cutting off the record carrier is not directly transmitted to the record carrier holding mechanism such as the platen. As a result, there is an effect that the record carrier holding mechanism is not adversely affected.
