DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety device for a commonly used desk paper cutting machine.

[0002]

2. Description of the Related Art In a table paper cutting machine, the blade is covered with a cover plate at the time of a cutting operation so that a finger does not accidentally enter a position below the cutting blade.
No. 15696, No. 57-9496, No. 2
No. 82498 is known, and utility model registration No. 30142 which cannot be cut unless the blade pressing handle and the button of the safety device are operated at the same time when the blade is pressed.
No. 62 devices are also known.

However, in the structure of the above-mentioned conventional table paper cutting machine, the structure of the cutting machine itself is simple in the former, and the finger is erroneously cut during the cutting positioning operation of the cut paper in the latter. There was an accident in which the operator pulled the lock knob and continued the work without knowing that the locked state was released, causing the handle to malfunction and dropping the cutting blade.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a complete safety device which has eliminated the above-mentioned disadvantages.

[0005]

According to the present invention, there is provided a safety cover body having left and right frame portions which are vertically and horizontally opened and closed in contact with a front opening of a central cover body provided with a handle and a cutting blade body. A part of the safety cover body is provided with a frame window for a safety knob for fixing and releasing a handle provided on a front part of the center cover body.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Now, when using the present invention,
Before the start of use, the handle is fixed at the uppermost position because the lock knob is in, so after moving the paper hitting ruler along the guide plate and moving the scale to the position of the required cutting dimension, The safety cover is raised upright to open the opening of the central cover, from which the cut paper is inserted and placed on the scale, and abuts the guide plate and the paper setting ruler.

[0007] When the cut sheet is placed and set in this way, the safety cover body is again laid down horizontally, and then the safety knob is pulled forward. Then, the lock of the handle is released.

In such a state, if the handle is pressed down with the handle, the cutting blade body is lowered, and at the same time, the paper restraining plate is also lowered to cut while suppressing the paper to be cut. During this time, the safety cover body is horizontally laid down on the front side of the opening of the central cover body, and serves as a barrier to prevent fingers from entering inward.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 denotes a base. An extractor 2 is installed in one side of the base to accommodate tools and the like, and the extractor 2 and the opposite side are used for lifting the body. Handle parts 3 are provided.

Reference numeral 4 denotes a dimensional scale provided on the surface of the base 1. A guide plate 5 is provided at a side edge of the scale, and a paper contact ruler 6 which slides at a right angle is provided on the guide plate. .

Reference numeral 7 denotes a central cover body provided with a cutting blade body 8 and a mounting base end 9 'of a handle 9, and side cover bodies 10, 10 are screwed on both front and rear sides of the central cover body. It is mounted so that it can be opened and closed via knobs 11 and 11. The detachment and attachment of the side cover body by the screw picking are performed when the cutting blade body 8 is replaced.

Reference numeral 12 denotes a safety knob provided on a part of one side of the front portion of the central cover body 7. When the safety knob is pushed inward, the handle 9 remains locked. For this reason, the handle is held in a fixed state even when the handle is moved downward. When the safety knob 12 is pulled out, the internal member that has locked the handle comes off, and if the handle is moved down in this state, the cutting blade 8
Also move down at the same time.

Reference numeral 13 denotes an opening in the form of a gate in the front of the central cover 7, and the cutting blade 8 is provided at an upper portion inside the opening. The cut sheet a is inserted from the opening in the direction of the scale 4.

Reference numeral 14 denotes left and right frame portions 14 ', 1 provided with hinges 15, 15 at the lower end portion at the front portion of the central cover body 7 so as to be opened and closed vertically and horizontally through the hinges.
A safety cover body having a front U-shape having a 4 'is provided with a box-shaped window 16 having a frame formed around the safety knob 12 in a part of the safety cover body.

Reference numeral 17 denotes a magnet provided at the center of the front portion of the center cover body 7. The magnet is a member for abutting and fixing the safety cover body when the safety cover body stands upright in use. Therefore, the magnet 1
At least a part of the safety cover body 14 which comes into contact with 7 is made of metal.

[0016]

According to the present invention, when the paper cutting machine is used, the safety cover body is provided as a barrier so as to lie horizontally on the front surface of the cutting blade body in the opening so as to cover the opening. Thus, there is no possibility that the user touches the paper, and the work of supplying the paper to be cut and the work of cutting the paper can be always performed safely and safely.

Further, the upright state of the safety cover body can be securely fixed and held by the magnet.
