Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a punching machine for punching a necessary hole in a document for filing a document or the like in a binder, and more particularly to a punching machine capable of easily positioning a punching position.

[0002]

2. Description of the Related Art Conventionally, in this type of punching machine, two methods are largely adopted as a method of determining a punching position. One is a method of installing a guide indicating the edge of the paper, and the other is a method of installing a guide indicating the center of the paper.

[0003]

However, in the punching machine adopting the former method of installing the guide indicating the edge of the paper, it is simple and easy to use, but at least the size from the punching position to the edge of the paper is small. Will be needed. Therefore, miniaturization is difficult, and it was used only in a stationary drilling machine.

Further, the latter punching machine adopting the method of installing the guide showing the center of the paper is often used for the handy type punching machine because it is easy to downsize, but it is difficult to find the center of the document. Generally, a document is folded in half and the crease is attached to the center as a guide. Others use a mirror to find the center (see, for example, Japanese Patent Laid-Open No. 2001-157995). But,
The method of folding a document in half and using the crease at the center as a guide requires an extra step and has the problem of leaving unnecessary creases on the paper. , Folding itself is difficult. Also,
The method of finding the center using a mirror has a problem that the operation is troublesome.

An object of the present invention is to provide a punching machine which is compact and can be easily positioned by mounting a distance meter for measuring the amount of paper feed on the punching machine for documents.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. (Embodiment 1) FIGS. 1 and 2 show Embodiment 1, in which a punching machine 1 includes a base 2, a handle 3, cylindrical blades 4, 4 and a bracket 5 for supporting a handle 3.
5, a distance meter 6, a positioning display lamp 7, a paper changeover switch 8 and a reset switch 9. The base 2 is provided with receiving holes 10 and 10 corresponding to the cylindrical blades 4 and 4, and the cylindrical blades 4 and 4 move up and down with the rotation of the handle 3 to receive the receiving holes 10 and 10. The paper is punched in cooperation with. 11 is a receiving hole 10, 10
When the paper 12 is inserted from the direction of arrow 13, for example, the paper is punched at a position equidistant from the center line 11.

The distance meter 6 is for measuring the insertion distance of the paper 12, and for example, an optical distance meter is used. FIG. 5 shows an outline of distance measurement by the range finder 6 using an optical movement measuring chip used in an optical mouse or the like. The distance meter 6 includes a light emitting diode (LED) 14, an incident light condensing lens 15, a reflected light condensing lens 16, an image sensor 17, a signal processor 18, and an up / down counter 19. The image sensor 17 and the signal processor 18 are integrated into a chip, and the light emitting diode (LED) 14,
There are commercially available products that include the incident light condenser lens 15, the reflected light condenser lens 16, and the like. The incident light 22 from the LED 14 is
The surface of the paper 12 is illuminated to become reflected light 23. Reflected light 23
Is condensed by the reflected light condensing lens 16 and forms a grayscale image on the image sensor 17.
Since the incident light is radiated obliquely, the obtained image has a pattern with light and dark depending on the place even if it is a white paper due to the fine unevenness of the paper surface of the paper 12. The light-dark pattern moves on the image sensor 17 as the paper 12 moves. The signal processor 18 generates two rectangular pulses, which are so-called A phase and B phase, which are 90 degrees out of phase, in order to distinguish the advance / return according to the movement amount. With a commercially available optical movement measurement chip,
The two pulses are output for each of the two directions on the plane, x and y. In the distance meter used in the present invention, it is sufficient to use only one direction that matches the paper feeding direction. The up / down counter 19 counts up and down by two pulse outputs of the A phase and the B phase from the signal processor 18. As a result, the cumulative pulse count value from the zero-reset location, that is, the count value corresponding to the distance is obtained.

Using this, the drilling position is presented to the operator as follows. In the punching position setting device 21, a pulse count value is set according to the distance from the sheet edge to the punching position and the offset where the distance meter 6 is installed and the position of the cylindrical blade 4 for punching. . When the value set in the punching position setting device 21 in the comparator 20 and the value in the up / down counter 19 are compared and coincide with each other, it is determined that the cylindrical blade 4 is at the drilling position, and the positioning display lamp 7 is turned on. In an actual device, since the resolution is extremely high at 400 pulses / inch and 800 pulses / inch, the positioning indicator lamp 7 lights up only for a moment. This makes it difficult for a general operator to use, and in order to avoid it, it is sufficient to give a wide range to the determination of the coincidence within a practically allowable error range.

Other optical rangefinders use a speckle pattern. In this device, when laser light is applied to an object having unevenness, a light-dark pattern of light corresponding to the unevenness is obtained due to interference. This is called a speckle pattern, and the rangefinder 6 is configured by performing the same processing as the rangefinder using the optical movement measuring chip used in the optical mouse or the like on the bright-dark pattern. be able to.

In the first embodiment, the rangefinder 6
Is provided in the center of the punch, that is, in the center of the cylindrical blades 4, 4 and the receiving holes 10, 10. The paper changeover switch 8 sets the size and direction (vertical / horizontal) of various papers 12 to be punched, and the reset switch 9 resets the distance meter 6 to zero.

To punch the sheet 12, the reset switch 9 is pressed to reset the distance meter 6 to zero, and the sheet size and direction (vertical / horizontal) are set by the sheet changeover switch 8.
Check if the settings are correct, and if they are different, set them correctly. Then, the paper 12 is inserted from the direction of the arrow 13 and scanned by the distance meter 6. For example, the display lamp 7 lights up when the insertion of the distance of 1/2 of the paper size is measured with the center line 11 as the starting point. At this time, when the handle 3 is pushed down, the cylindrical blades 4 and 4 descend and punch at two points equidistant from the center of the paper 12. So without inserting a mark on the paper, simply insert the paper,
It is possible to punch at an appropriate position by a simple operation of pushing down the handle 3 at a position where the positioning display lamp 7 is turned on.

Further, in the punching machine of the type in which the paper 12 is inserted from both directions, the feeding distance from one direction is 1/2.
In this case, the positioning indicator lamp 7 may be lit up even at a distance of -1/2 so that the positive and negative signs of the forward and backward distances are automatically determined.
The example of FIGS. 1 and 2 is for a standard two-hole type, but since only the center position of the paper is detected using a range finder, various types of punching machines such as three-hole type punchers are used. Is applicable to.

(Embodiment 2) In FIG. 3, the distance meter 6 is moved from the center 11 of the drilling machine by a distance L1 (L1 is a positive value) and the arrow 1
It shows a punching machine that is installed in three different directions,
Other configurations are similar to those of the first embodiment. In this case, the positioning display lamp 7 is turned on when (1 / 2-L1) feed of the size of the paper 12 is detected. On the contrary, when the distance meter 6 is installed so as to be displaced from the center 11 of the punching machine by the distance L1 (L1 is a positive value) in the direction opposite to the arrow 13 direction, the size of the paper 12 is (1/2 + L1). The positioning display lamp 7 may be turned on when the feed is detected. Further, the insertion direction of the paper is not limited to the direction of the arrow 13, and it is possible to insert it from the opposite side. In the case of the distance meter arrangement shown in FIG. (1 / 2−L1) should be set. Further, when the arrangement of the rangefinder is reversed, the positioning display lamp 7 may be turned on when the feed of-(1/2 + L1) is detected. From these facts, it can be seen that the distance meter 6 may be installed outside the drilling position.

(Third Embodiment) FIG. 4 shows a single-hole punching machine as an example of a general-purpose punching machine. In this example, the cylindrical blade 4 and the receiving hole 10 are provided one by one, and the distance meter 6 is installed at the position 22 which is displaced from the drilling position 21 by the distance L2 in the direction opposite to the arrow 13 direction.
In this punching machine, the paper changeover switch 8 is configured so that not only the size and direction of the paper but also the position and number of punches and the like can be set according to the type of binder.
The deviation L2 between the punching position of the sheet and the position of the distance meter 6 and the position of the cylindrical blade 4 for punching is an offset, and as shown in FIG. The value read by the distance meter 6 when it coincides with the cylindrical blade 4 is the value (positive value). Contrary to FIG. 4, when the distance meter 6 is on the opposite side of the punching cylindrical blade 4, when the sheet is inserted from the side opposite to the arrow 13 direction, the sheet edge B on the opposite side is the punching cylindrical blade. The value read by the rangefinder when it matches 4 is that value (negative value). Using this offset value L2, the relationship between the punching position of the paper and the installation position of the distance meter 6 is generally as follows. First, the punching positions from the sheet edge A when inserted from the direction in which the reading of the distance meter increases (the case shown in FIG. 4) are P1, P2, ..., Pn (n is the number of holes). Then, the perforation position according to the reading of the rangefinder is (P1 + L2), (P2 + L
2) ,,, (Pn + L2). Next, when the distance meter is inserted from the decreasing direction (when it is inserted from the opposite direction to that shown in FIG. 4), the punching position from the sheet edge B is set to Q1, Q
2, ..., Qn (n is the number of holes). In this case, Q1, Q
2, ..., Qn are negative values. Then, the drilling position according to the reading of the rangefinder is (Q1 + L2)
(Q2 + L2), ..., (Qn + L2). In many cases, the holes are symmetric, so P1 = -Q1, P2 = -Q2, ...
There is a relationship of Pn = -Qn. Therefore, the punching position from the sheet edge B when the distance meter is inserted from the decreasing direction is −
(P1-L2),-(P2-L2), ...,-(Pn-L2).
Therefore, the size of the paper
By setting not only the direction (vertical / horizontal) but also the position / number of perforations according to the type of binder, it is possible to perforate flexibly according to the binder.

For example, letter size (the long side length of the paper is
The perforation position of the three-hole binder used for 11 inch ≈ 279.4 mm) is as follows: Punch position 1 (P1) = 1.25 inch ≈ 31.7 mm Punch position 2 (P2) = 5.5 inch ≈ 139.7 mm Punch position 3 (P3) = 9.75inch ≈ 247.6mm, and the reverse piercing position is piercing position 1 (Q1) ≈ -31.7mm, piercing position 2 (Q2) ≈ -139.7mm, and piercing position 3 (Q3) ≈ -247.6mm. Also, the two holes commonly used in Japan are
The spacing is 80 mm. Therefore, the long side of A4 paper (29
6 mm), the drilling position is 1 (P1) = 108 mm, 2 (P2) = 188 mm, and the reverse drilling position is 1 (Q1) =-108 mm 2 (Q2) ) =-188mm.

(Fourth Embodiment) In the first to third embodiments, the range finder 6 is an optical range finder.
Instead of this optical range finder, a known mechanical range finder using a disk or a rolling ball may be used. In this case, the disc or ball is rotated by contacting the sheet to be inserted, and the insertion distance of the sheet is measured from the number of rotations.

(Embodiment 5) If the size of the paper is not a prescribed size, the size of the paper cannot be specified by the paper changeover switch 8. Therefore, the paper to be punched is fed once in advance, the distance from the starting end to the end of the paper is measured by the distance meter 6, and this distance is input to the arithmetic unit 19 of the distance meter 6, and the A function of turning on the display lamp 7 when the sheet reaches the punching position by inserting the sheet is added. With this function, it becomes possible to punch a sheet of any size at an appropriate position with respect to the center line without setting by the sheet changeover switch.

(Embodiment 6) The method of presenting the positioning state is not limited to the method of turning on the display lamp described in the above embodiment, and various visual means can be used. Further, as a method of presenting the positioning state, not only visual means but also auditory means such as sound and tactile means such as vibration can be used.

(Embodiment 7) A driving mechanism such as a motor for driving a punching blade is provided, and when it is detected that the sheet has reached the punching position, not only the display but also automatic driving is performed. It is also possible to operate the blade for punching by a mechanism to punch the blade.

[0021]

According to the present invention, the following effects can be obtained. (1) It is possible to punch at a predetermined position without making a mark such as folding a document to be punched, and it is possible to downsize the punching machine. (2) The punching position can be visually, audibly or tactually displayed only by inserting the sheet to be punched into the punching machine, so that the punching operation can be simplified. Further, the paper can be inserted in either direction. (3) Paper size, direction (vertical / horizontal) or number of punches,
Since the punching position can be set, punching can be performed for various types of paper and binder. (4) Even if the paper size or the like is unknown, the document can be punched at a desired position by scanning the document once in advance.
