[Problems to be solved by the invention]
By the way, among the above-mentioned prior arts, the cutter device described in Japanese Patent Application Laid-Open No. 2002-127081 (Patent Literature 1) is configured such that the cutter device has a round blade from a fixed position for performing full cut on a sheet to be cut. The printer is fixed to the inside of the printer apparatus by being shifted by a predetermined distance in the cutting movement direction, so that the round blade switches to the return stroke before finishing the entire width of the roll paper. However, in the case of this cutter device, since a space for mounting the printer at a shifted position is required inside the printer device, there is a problem that the width of the printer device is correspondingly widened. It becomes a problem when it is used by being incorporated in another device.
[0005]
Further, a cutter device described in Japanese Patent Application Laid-Open No. 2002-127080 (Patent Document 2) is provided with a U-shaped groove on a side surface of a moving blade carrier holding a round blade, and a carrier feeding belt is provided. The fixed carrier connecting member is slidably engaged with the U-shaped groove so that it cannot enter from a predetermined position in one direction by a restricting member, and the carrier is fed at the time of full cut and partial cut. The direction of rotation of the belt is reversed, so that the carrier connecting member stays in the groove on the cutting standby position side during the full cut, and the carrier connecting member moves to the groove on the cutting moving direction side during the partial cut, so that the U-shaped groove is formed. The switch between full cut and partial cut is made using the distance between the left and right grooves, and the final user can freely select both by the control means. It has become what it can be. However, many complicated parts are required, the structure of the entire apparatus becomes complicated, and noise may be generated due to contact between the parts.
[0006]
Next, a cutter device described in Japanese Patent Application Laid-Open No. 2002-219688 (Patent Document 3) has a rotary drive belt that has a tooth profile on an inner peripheral surface, is wound around two pulleys, and rotates in only one direction. Using the notch gear which is held in the cutting blade holder and is located in the middle of the upper and lower rotary drive belts and has a notch tooth part in which some teeth are missing, the notch part of the notch gear faces upward In this case, the teeth of the missing tooth gear mesh with the lower belt, and as a result, the round blade is moved in the same direction as the movement direction of the lower belt. Conversely, when the missing tooth portion of the missing tooth gear faces downward, the missing tooth is formed. The teeth of the gear mesh with the upper belt, thereby moving the round blade in the same direction as the movement direction of the upper belt. Greater than or equal to When a rolling force is applied, the missing tooth gear rotates half and the meshing between the rotary drive belt and the missing tooth gear is turned upside down, so that the moving direction of the round blade is switched, and the position of the stopper member is changed. This makes it possible to select between full cut and partial cut. However, also in this case, the number of components increases, and furthermore, the possibility that noise is generated cannot be denied. In addition, an excessive load is applied to the drive belt and the pulley shaft, and it is necessary to take measures such as making the pulley shaft thicker.
[0007]
The present invention is directed to a printer device in which the width of the printer device is increased in the conventional cutter device as described above, or a printer device in which the end user can freely select between full cut and partial cut. For this reason, a complicated mechanism is used to increase the weight of the cutter device or increase the cost of the cutter device more than necessary, or in a small printer device for receipts or the like. The function that allows the end user to freely switch between full cut and partial cut is not necessarily required, and it is made in view of the reason that the printer is often assembled exclusively for full cut or partial cut at the shipping stage of the printer. First, the structure is almost the same as that of a simple full-cut cutter device. The first objective is to provide a cutter device dedicated to partial cuts that can perform partial cuts until then, and it is easy to switch between partial cuts and full cuts not only at the shipping stage but also by the end user using the same cutter device. It is a second object of the present invention to provide a cutter device that can perform the above operations.
[0008]
[Means for Solving the Problems]
SUMMARY OF THE INVENTION The present invention has been made to achieve the above-described object, and a first invention is a flat plate-shaped plate having a cutter frame and a top plate fixed to the cutter frame and having an upper surface also serving as a receiving plate for a sheet to be cut. A fixed blade, a round blade holder that reciprocates in the longitudinal direction of the fixed blade along a moving path provided in the cutter frame so as to be parallel to the fixed blade, and rotatably held by the round blade holder A fixed blade, the cutting edge of the fixed moving blade being pressed against the cutting edge of the fixed blade, and a driving means for reciprocating the round blade holder. In the cutter device for cutting a sheet to be cut in the width direction by the cutting edge of the fixed blade, a cutting device is provided with a cutout portion at the cutting edge on the cutting end side of the fixed blade.
[0009]
According to a second aspect of the present invention, in the above-described cutter device, the fixed blade can be slid by a predetermined distance in the longitudinal direction of the cutter frame, and the fixed blade can be fixed at at least two positions of the cutter frame. And
[0010]
According to the cutter device of the present invention, a lightweight and inexpensive cutter device dedicated to partial cutting can be obtained by a simple mechanism, and the partial blade can be easily slid by allowing the fixed blade to slide with respect to the cutter frame. It is also possible to obtain a cutter device capable of switching between cutting and full cutting.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to FIGS. FIG. 1 is a front view showing an embodiment of a sheet cutting device according to the present invention, and FIG. 2 is a front view when a front frame cover 50 is removed. FIG. 3 is a plan view of FIG. In the figure, a fixed blade 1 made of a thin steel plate is fixed to an upper portion of a cutter frame 3 by a fixing means such as an adhesive, spot welding, or a screw, and the upper surface of the fixed blade 1 is Since it also serves as the receiving plate, the length of the fixed blade 1 is longer on both sides than the width W of the sheet P to be cut.
[0012]
On the other hand, a moving path 5 is provided in the cutter frame 3, and the moving path 5 serves as a guide when the round blade holder 4 holding the round blade 2 reciprocates in the left and right direction of the cutter frame 3. . The fixed blade 1 is fixed to the upper portion of the cutter frame 3 so that the moving path 5 and the cutting edge 11 of the fixed blade 1 are parallel.
[0013]
The round blade holder 4 is located above the fixed blade 1 and rotatably holds the round blade 2. The round blade case 41 is located under the fixed blade 1 and slides along the moving path 5. The round blade case portion 41 and the sliding holding portion 42 are integrally connected by a connecting portion 43 straddling the cutting edge 11 of the fixed blade.
[0014]
Pulleys 8, 8 are rotatably supported near the left and right ends of the cutter frame 3 by pulley shafts 7, 7, and the pulleys 8, 8 have a motor 6, a driving gear 13 and a driven gear. The wire 9 is engaged with the sliding holding portion 42 so that the wire 9 which is alternately switched in the left-right direction is driven by the driving means 14 and the like, and is pulled by the wire 9 so that the round blade holding table 4 reciprocates. Has been stopped.
[0015]
The round blade 2 is rotatably supported on the round blade case 41 by a pin shaft 15, and the cutting edge in the cutting movement direction X side of the round blade 2 is a fixed blade by a biasing means incorporated on the side surface of the round blade 2. It is constantly pressed against the cutting edge 11. The paper P to be cut is cut in the width direction when the round blade holder 4 moves in the cutting movement direction X. At this time, the round blade holding table 4 is moved by a distance exceeding the width of the cut paper P when the cutting point S of the cutting edge S of the round blade 2 enters the width direction of the cut paper P sent to the upper surface of the fixed blade 1. The driving means is controlled by a separately provided control means (not shown) so as to be reciprocated by the wire 9.
[0016]
On the other hand, a notch 12 is provided at the cutting edge of the fixed blade 1 at the cutting end, and the cut-end side end of the sheet P to be cut sent to the upper surface of the fixed blade 1 has a predetermined amount in the width direction. R is cut out so as to pass over the notch 12. The press-contact between the cutting edge 11 of the fixed blade and the cutting point S of the round blade 2 is released by the notch 12 of the cutting edge, so that the cut sheet P is not cut at the notch 12 and the cut sheet P is not cut. An uncut portion is formed at the end of cutting, and a partial cut is obtained. In addition, even if the notch 12 is provided in the fixed blade 1, the entire length of the fixed blade 1 does not change, so that the function as the receiving plate of the sheet P to be cut is maintained as it is.
[0017]
Next, FIG. 4 shows a cutter device in which the fixed blade 1 provided with the notch portion 12 is slidable by a predetermined distance Y in the longitudinal direction of the cutter frame 3 in the cutting movement direction X of the round blade 2. A plurality of stop pins 21 provided on the upper surface of the cutter frame 3 and a deformable slot 22 and a slot 23 provided on the fixed blade 1 so as to match the stop pins 21 are slidable. The fixed blade 1 is locked by the stopper pin 21 at a predetermined position of the odd-shaped slot 23.
[0018]
The distance Y at which the fixed blade 1 can slide with respect to the cutter frame 3 is determined such that the notch 12 extends from the cut end side edge of the cut paper P sent to the upper surface of the fixed blade 1 in the width direction of the cut paper P. This is the distance traveled until it is slightly separated. As a result, the press-contact state between the cutting edge 11 of the fixed blade and the cutting point S of the round blade 2 is maintained until the cutting edge of the cutting target paper P passes beyond the cutting end side, so that the cutting target paper P is cut over the entire width. A full cut is obtained. The value of the moving distance Y is such that the fixed blade 1 does not protrude in the length direction of the cutter frame 3 even when the fixed blade 1 is slid with respect to the cutter frame 3.
[0019]
In addition, other fixing means such as a screw can be adopted in place of the above-mentioned locking pin 21, and the screw is used to fix the fixing blade 1 in the length range (Y) of the long hole provided in the fixed blade 1. Since the fixing position of the blade 1 can be changed, the width of the uncut portion of the sheet P to be cut at the time of partial cutting can be adjusted.
[0020]
In FIG. 4, the fixed blade 1 having the modified elongated hole 22 and the modified slot 23 has been described. However, the fixed blade 1 having the modified elongated hole 22 on both sides may be used. Reference numeral 24 denotes a moving knob formed by bending the end of the fixed blade 1.
[0021]
