Description

[Detailed Description of the Invention] The present invention relates to an electric opening device equipped with a cutter for opening an object to be cut, such as an envelope.

As shown in FIGS. 5 and 6, this type of conventional electric unsealing device has a main body case 21a that constitutes a main body 21 and a main body cover 21b that have approximately the same width, and has a A chassis 25 is equipped with a pair of upper and lower cutters 22, 23 for opening an object to be cut, such as an envelope, a switch lever 24, etc., which is operated when the object to be cut is inserted, and the chassis 25 is equipped with a pair of upper and lower cutters 22, 23 for opening an object to be cut, such as an envelope, and a switch lever 24, which is operated when the object to be cut is inserted. One end of the table 26 on which the object to be cut is placed is attached, and the other end of the table 26 projects outward from an opening 27 provided between the main body case 21a and the main body cover 21b. Due to the heat, the width of the entire electric unsealing device has to be increased in order to secure the 26 table surfaces to a predetermined size, which not only takes up space on the desk when in use, but also increases the volume of the package when packed. The problem is that the larger the size, the higher the packaging and transportation costs, resulting in higher costs.

In view of the above-mentioned conventional drawbacks, the present invention aims to increase the table surface on which an object to be cut, such as an envelope, is placed, and to reduce the size of the entire electric opening device.

The basic structure of the present invention to achieve the above object is that, of the main body consisting of a main body case and a main body cover, the width of a part of the main body cover is made sufficiently smaller than the width of the main body case, and the width of a part of the main body cover is made to be biased to one side. At the same time, the table is attached to the main body case so that an opening is formed through which the object to be cut, such as an envelope, passes, and the guide portion of the table on which the object to be cut, such as an envelope, is placed is located in a part of the main body cover. It is fixed on top.

By adopting the above structure of the present invention, it is possible to secure the table surface to a predetermined size, and the end surface of the table does not protrude outward from the main body case, so the width of the entire electric opening device is reduced. The width of the electric unsealing device does not exceed the width of the main body case, and as a result, the overall shape of the electric unsealing device can be reduced, thereby reducing packaging and transportation costs.

An embodiment of the present invention will be described below with reference to the accompanying drawings. Fig. 1 shows a perspective view of the electric unsealing device, and 1 is the electric unsealing device main body. The main body cover 1b is detachably attached above the case 1a. 3 is a table, this table 3
This is for placing an object 4 to be cut such as an envelope, and a guide portion 3a for guiding the insertion of the object 4 to be cut is integrally bent at a substantially right angle at the rear. 5 is an upper cutter, 6 is a lower cutter, and 7 is a switch lever.

FIG. 2 shows a cross-sectional view of the electric unsealing device. Reference numeral 8 denotes a chassis mounted between the main body case 1a and the main body cover 1b, and this chassis 8 has a plurality of boss parts. 9 are integrally formed. Reference numeral 10 denotes an electric motor attached to and supported by the plurality of boss portions 9 with screws 11;
3, 14, 15 are transmission gears, and 16, 17 are upper cutter shafts and lower cutter shafts that transmit the power of the electric motor 10 to the upper cutter 5 and lower cutter 6 via transmission gears 12, 13, 14, 15, respectively. be. Further, a switch 18 operated by a switch lever 8 is fixed to the chassis 8, as shown in FIGS. 3 and 4, and this switch 18 is electrically connected to the electric motor 10.

In addition, in FIGS. 1 and 2, the main body cover 1b is installed so that the width of a part thereof is sufficiently smaller than the width of the main body case 1a and is offset to one side, and the switch lever 7, the upper and lower cutters 5 . Further, the table 3 is fixed on the main body case 1a such that the guide portion 3a of the table 3 is located in a part of the main body cover 1b. In this case, the guide portion 3a of the table 3 and the front surface 8a of the chassis 8 are arranged to be substantially on the same plane.

In the above configuration, when opening an object to be cut such as an envelope, the end surface of the object to be cut 4 is moved along the guide portion 3a on the table 3 from the left toward the opening 20. Due to this movement, the front end surface of the workpiece 4 pushes the switch lever 7 and
Rotate counterclockwise. This rotation causes the pressing member 7a of the switch lever 7 to press the knob 18a of the switch 18 in FIG. 4, thereby closing the switch 18 and energizing the electric motor 10. This electric motor 10
The upper cutter 5 and lower cutter 6 are rotated via transmission gears 12, 13, 14, and 15, and these upper cutter 5 and lower cutter 6 cut the object to be cut, such as an envelope that has passed through the switch lever 7. 4 is cut, unsealed, and transported. When the rear end surface of the object 4 to be cut, such as an envelope, passes, the pressing member 7a of the switch lever 7 is pushed back by the restoring force of the knob 18a of the switch 18, and the switch 18 is opened. As a result, the power supply to the electric motor 10 is stopped, and the rotation of the upper and lower cutters 5 and 6 is also stopped.

As described above, the electric unsealing device of the present invention has a main body consisting of a main body case and a main body cover, and the width of a part of the main body cover is made sufficiently smaller than the width of the main body case, and it is installed offset to one side. , an opening is formed through which the object to be cut such as an envelope passes, and the table is fixed on the main body case so that the guide part of the table is located in a part of the main body cover, so the table surface can be cut to a predetermined size. Not only can it be ensured that the electric opening Since the overall shape of the unsealing device can be reduced in size, packaging costs and transportation costs can be reduced.
