Description

The present invention relates to a cutter mechanism for cutting a member to be cut (tape member), a cutter device, and a tape printing apparatus including the cutter device.

Conventionally, a tape printing apparatus has a tape-like member (tape member) having release paper and an adhesive.
Tape member (so-called label) that has been printed by the user and cut to the desired length
Can be created. Then, the release paper is peeled off from the created label and attached to the object intended by the user, thereby displaying the object. Label display
Compared with display by handwritten characters, etc., it has a better appearance, and it is not necessary to apply glue, so that the display operation can be performed quickly without getting the hands dirty. Such tape printers with high convenience are widely used from office use to home use.

The label produced by the tape printer has a rectangular outer shape, and the four corners of the label end are cut at substantially right angles. For this reason, the appearance quality (softness, etc.) of the label can be improved by chamfering (cutting at a fixed inclination angle) or R-cutting (cutting with a curved shape such as an arc) at the corner of the label. To improve,
Prevents peeling of labels from corners.

Patent Document 1 discloses a cutter mechanism that performs chamfering and R-cutting on a corner of a tape member, and a cutter mechanism that performs cutting into a shape that is changed with respect to an end portion other than the corner.

Japanese Patent No. 3482765

The cutter mechanism of Patent Document 1 is a chamfering or R-cut for a tape member having a specific (one type) tape width, with two corners at the end portion set according to the tape width. However, chamfering or R-cutting to a size corresponding to the tape width could not be performed on tape members having different tape widths. As a result, when a tape member having a tape width narrower than a specific tape width is cut (chamfered or R-cut) by the cutter mechanism in Patent Document 1, the cut is larger than the tape width. Similarly, when a tape member having a tape width wider than a specific tape width is cut by the cutter mechanism in Patent Document 1, the cut is smaller than the tape width. In particular, when a tape member having a tape width having a large difference from a specific tape width is cut, the appearance (appearance quality) may be deteriorated.
Therefore, there has been a demand for a cutter mechanism, a cutter device, and a tape printing device that can be chamfered or R-cut in sizes corresponding to different tape widths and can be reduced in size.

SUMMARY An advantage of some aspects of the invention is to solve at least a part of the problems described above, and the invention can be implemented as the following forms or application examples.

[Application Example 1] A cutter mechanism according to this application example is formed of a flat plate member, and has a plurality of blade parts configured by a fixed blade and a movable blade that are opposed to each other on a plane and cut a member to be cut. The blade portion is formed in a shape corresponding to a different width of the member to be cut.

According to such a cutter mechanism, since it has the some blade part formed in the shape according to different to-be-cut member width (width of a to-be-cut member), for example, a tape member differs as a to-be-cut member. When having a tape width, for example, a corner can be cut into a set shape by using a blade portion (a fixed blade and a movable blade) having a shape corresponding to the tape width. Therefore, the corner can be chamfered or R-cut with a size corresponding to a different tape width.

Application Example 2 In the cutter mechanism according to the application example described above, the cutter unit is formed at a part of a connection part that integrally connects the blade part in a loop shape and a part of the connection part that allows the movable blade to move relative to the fixed blade. Each of the pair of blades, each of which has a pair, each of which has a shape set for each pair, and the distance corresponding to the width of the member to be cut is set as shortest as possible. It is preferable that a pair of blade portions whose distance is set longer in the direction is formed sequentially, and the connecting portions are respectively disposed on both sides of the outermost pair of blade portions.

According to such a cutter mechanism, for example, even when the tape member as the member to be cut has a different tape width, a pair is formed with a separation distance corresponding to the tape width, and the shape is set for each pair. Using the blade, for example, two corners can be cut in a set shape. In addition, a pair of blade portions whose separation distance is set to be long is formed sequentially in both sides of the pair of blade portions whose separation distance is set to be the shortest, and the connecting portions are both sides of the outermost pair of blade portions. Since the movable blades connected to the fixed blade and the flexible part are integrally connected in a loop shape, the constituent parts of the cutter mechanism are arranged efficiently and a cutter mechanism that can be downsized is realized. To do.

Application Example 3 In the cutter mechanism according to the application example, along the insertion direction of the member to be cut,
It is preferable that a pair of blade portions whose distance is set to be short is disposed sequentially.

According to such a cutter mechanism, for example, even when the tape member as the member to be cut has a different tape width, the pair of blade portions are sequentially reduced in the separation distance along the insertion direction of the member to be cut. Therefore, for example, a tape member having a wide tape width is cut by a pair of blade portions arranged on the front side in the insertion direction, and a tape member having a narrower tape width is a tape having a wide tape width. It can cut | disconnect with the pair of blade part arrange | positioned rather than the pair of blade part which cut | disconnects a member in the back side along an insertion direction. Thereby, when a tape member with a wide tape width is inserted and cut, the blade portion for cutting the tape member with a narrow tape width can be prevented from interfering with the tape member with a wide tape width. Moreover, even if the blade portion for cutting the tape member having the narrow tape width performs the cutting operation, the influence of damaging the end portion of the tape member having the wide tape width can be prevented.

Application Example 4 In the cutter mechanism according to the application example described above, it is preferable that the blade portion is disposed substantially symmetrically with respect to the central axis along the insertion direction of the member to be cut.

According to such a cutter mechanism, a more efficient and balanced arrangement can be achieved, and a cutter mechanism that can be further reduced in size can be realized. In addition, not only the positions of the fixed blade, the movable blade, the connecting portion, etc., but also the shape of the cutter mechanism is arranged substantially symmetrically with respect to the central axis, the design efficiency of the cutter mechanism can be improved.

Application Example 5 A cutter apparatus according to the application example described above is installed in any one of the above-described cutter mechanisms, a drive unit serving as a base for driving the movable blade to be movable, and driving of the drive unit. And a drive transmission unit that transmits force to the movable blade.

According to such a cutter device, the driving force of the drive unit is efficiently transmitted to the movable blade by the drive transmission unit installed in the connecting portion, and the movable blade having a shape set corresponding to the tape width is moved. enable. Thereby, even when the tape members have different tape widths, a cutter device that can cut a corner with a movable blade having a shape set corresponding to the tape width is realized.

Application Example 6 In the cutter device according to the application example, the drive transmission unit is connected to the connection unit.
It is preferable that it is installed in the site | part facing the substantially center site | part of a pair of blade part.

According to such a cutter device, the drive transmission unit is installed at a portion of the coupling portion that is opposed to the substantially central portion of the pair of blade portions, so that the drive transmission unit is efficiently balanced.
The driving force can be transmitted to the connecting portion and the flexible portion, and a plurality of pairs of movable blades corresponding to the plurality of pairs of fixed blades can be driven (moved). In addition, a driving force can be transmitted by one drive transmission unit, and a cutter device that can be reduced in size is realized.

Application Example 7 In the cutter device according to the application example described above, the cutter device includes a storage case that stores the cutter mechanism, and the storage case includes an insertion guide portion that guides the member to be cut and inserts the member into the cutter mechanism. Preferably, the portion has a guide groove, and the guide groove is formed corresponding to the separation distance, and the groove is formed deeper as the separation distance becomes shorter.

According to such a cutter device, the guide groove of the insertion guide portion is formed corresponding to the separation distance, and the guide groove is formed deeper as the separation distance becomes shorter. Thereby, for example, even when the tape width of the tape member as the member to be cut is different, the tape width (separation distance) is formed by forming the guide grooves deeply in the order of decreasing the tape width (separation distance).
It is possible to form insertion guide portions each having a guide groove adapted to the above. Therefore, tape members having different tape widths can be stably guided along the guide groove of the insertion guide portion corresponding to the tape width, and can be properly inserted into the corresponding blade portion of the cutter mechanism.

Application Example 8 A tape printer according to the application example includes any one of the above-described cutter devices,
A mounting section for mounting a tape cartridge for winding and housing a tape member having release paper and an adhesive, a printing section for mounting the tape cartridge to print on the tape member, and a tape member for printing by the printing section A cutting portion that forms a member to be cut by cutting, inserts the member to be cut into a cutter device, and cuts a corner at an end of the inserted member to be cut.

According to such a tape printer, the tape cartridge is mounted on the mounting portion, and printing is performed on the tape member by the printing portion. Further, the member to be cut is formed by cutting the printed tape member at the cutting portion. Then, the member to be cut is inserted into the cutter device to cut the corner at the end of the member to be cut. Thereby, the tape printer which can cut | disconnect a corner with the shape set with respect to different tape width is realizable. Further, this tape printer can improve the appearance quality as a label for tape members having different tape widths.
