Description

[Detailed description of the invention] This invention relates to a cutting device, and more specifically, the cutting blade is moved diagonally up and down in conjunction with the vertical movement of the operating handle, and the lowered position of the cutting blade is illuminated by light from a light source. The present invention relates to a cutting machine that makes it easy to cut a large number of paper sheets by using a beam to display information on the base plate or on the paper on the base plate, and to accurately register the intended cutting position.

In a commonly used office cutting machine, one end of the cutting blade is pivoted to a base plate on which the paper sheets to be cut are placed, and the cutting blade is moved from the pivot point by a handle attached to the other end. When it is rotated around a fulcrum, it cuts paper sheets between it and a fixed blade attached to the side of the base plate,
Since the cutting blade does not move diagonally up and down like a large commercial cutting machine, it is impossible due to its mechanism to cut many sheets at once, but if you cut a little more paper sheets, it will cut cleanly. The drawback was that I couldn't do it. Furthermore, the above-mentioned commercial cutter has a disadvantage in that it is large in size and is not suitable for office use.

In order to eliminate these defects, a cutting machine equipped with a so-called hoisting mechanism that moves the cutting blade diagonally up and down has been proposed, but the mechanism for moving the cutting blade up and down is complicated, and the base plate There was a drawback in that it was difficult to visually estimate the so-called register cutting position of the paper sheets placed on top.

This invention aims to eliminate the above-mentioned drawbacks and is characterized by a handle that is pivoted between a pair of supports mounted on the base plate and fixed to the end of the pivot. A strong frame member that is rolled, a roller that is pivotally supported by the frame member and is in contact with the ridge of the cutting blade that is always supported under tension upwardly by an elastic member, and a roller that is pressed down by the roller when the frame member is rolled. A guide pulley is attached to the cutting blade to be inserted into an inclined hole made in a guide plate installed between the supports, and as the cutting blade moves upward, the guide pulley constantly applies downward pressing force with an elastic member. A paper press plate is attached to the cutting blade so as to be moved upward against the pressure, and a paper press plate is attached to one side of the cutting blade through a long and narrow gap provided between the cutting blade and the paper press plate in the center of the frame member. a light source that linearly irradiates a light beam onto paper sheets placed on a base plate; register point display means for irradiating a cutting line on the paper to be cut on the base plate; and a switch for the light source. The present invention provides a cutting device characterized in that it is equipped with a light source switch mechanism that closes the light source switch mechanism.
An embodiment of this invention shown in the drawings will be described in detail below.

Bar springs 25a and 25b are attached to the paper press plate 18 and bias the paper press plate 18 downward.

As shown in FIGS. 1 and 2, the base plate 1 has a positioning member 26 that determines the cutting dimensions of the paper sheets to be cut and the placement of the paper sheets on the base plate relative to the cutting blade.
An elongated hole 27 is formed in the area where the cutting blade 13 comes into contact, and a blade receiving material 29 made of synthetic rubber or the like is inserted into this elongated hole and a groove in a receiving material 28 attached below the elongated hole. Incidentally, an installation leg 2 is provided in the vicinity directly below the receiving material 28.

Furthermore, the paper sheet placed on the base plate 1 is illuminated with a light beam along one side of the cutting blade 13 through a gap 30 of approximately 0.3 to 0.7 mm provided between the cutting blade 13 and the holding plate 18 in the center of the frame member 4. A light source 31 that irradiates the sheet is provided so that the position where the cutting blade hits the sheet can be easily seen even if there is a cutter cover 33 attached to cover the cutting blade attachment mechanism as described later. be.

The flashing switch 32 for this light source is shown in Fig. 3a and b.
The wires are connected as shown.

The cutting machine of this invention is constructed as described above, and the operation of each part when cutting paper sheets using this cutting machine will be explained next.

In the state shown in FIGS. 1 and 2, the cutting blade 13 and the paper pressing plate 18 are connected to the coil springs 22a and 2.
2b has finished rising due to the elasticity of the paper sheet 2b. In this state, a stack of about 200 paper sheets a to be cut is placed on the base plate 1, and the cutting position is adjusted to another position using the well-known positioning member 26. Make the switch 32 perpendicular to the side and put it in standby mode.
When the light source 31 is turned on by closing the door, as described above, from the gap 30 between the cutting blade 13 and the holding plate 18,
Since the light from the light source illuminates the paper sheet a with a thin strip-shaped light beam, the registration area to be cut can be aligned with this light beam line, so it can be rotated by tilting the handle 6 toward you. When the frame member 4 falls counterclockwise as shown in FIGS. 5 to 10 with the rotation of the shaft 5, the rollers 7a and 7b, which are supported by the support shaft 8, move against the upper edge of the cutting blade 13. in contact with
The cutting blade 13 is connected to coil springs 22a, 22.
If you push down against the elasticity of b, the guide pulleys 14a,
14b is inserted into the inclined holes 12a, 12b, so it moves leftward and descends, and before the tip of the cutting blade comes into contact with the paper sheet a and cutting begins, the bar spring 25a is activated as the cutting blade 13 descends. , 25b begin to act, and the paper pressing plate 18 has already finished descending onto the paper sheets a, and presses and fixes them.

The operation handle 6 is further removed from the state where the cutting edge of the cutting blade 13 is in contact with the paper sheet a shown in FIGS.
When the cutting blade 13 is tilted forward, the cutting edge of the cutting blade 13 tilts further and moves downward to cut into the paper sheet a, as shown in FIGS.
When the cutting edge of the cutting blade 13 comes into contact with the paper sheet a, if the operating handle 6 is raised upward, the paper sheet a has been neatly cut at the desired cutting position.

The operating handle 6 is equipped with a coil spring 22a,
When the cutting blade 13 returns upward due to the elasticity of the member 22b, the frame member 4 returns together until it comes into contact with the stop rod 9.
The state returns to the state shown in FIGS. 1 and 2 again, and the next cutting can be performed.

As described above, this invention consists of a strong frame member that is pivotally mounted between a pair of supports mounted on a base plate and rotated by a handle fixed to the end of the pivot, and a strong frame member that is pivotably supported on the frame member. A guide plate attached between a roller that is in contact with the ridge of the cutting blade, which is always supported under tension upward by an elastic member, and a guide plate attached to the cutting blade that is pressed down by the roller when the frame member rolls. A guide pulley is attached to the cutting blade to be inserted into the inclined hole, and attached to the cutting blade so that as the cutting blade moves upward, the guide pulley constantly moves downward against the pressing force of the elastic member. A light beam is emitted along one side of the cutting blade from a long and narrow gap provided between the paper holding plate and the paper holding plate placed in the center of the frame member in a straight line onto the paper sheets placed on the base plate. The system is equipped with a light source that illuminates the paper to be cut, a registration point indicating means that illuminates the cutting line on the paper to be cut on the base plate, and a light source switch mechanism that closes the switch of the light source. In addition to being able to easily and neatly mark leaves accurately and having a simple mechanism, the handle is located off the base plate, allowing the use of as much space on the base plate as possible. As a result, the cutting operation can be performed more easily and accurately.
