3 to 5 are diagrams for explaining driving mechanisms of the conveying means, the recording section 20, and the cutting section 30 of the printer 1 according to the embodiment.

The main motor 5 transmits drive to the supply roller 2a, the platen roller 3, the conveying roller 4, and the reel shaft 45 via idler gears (not described). The relation of the conveying speed in each part is as follows: supply roller 2a<platen roller 3=conveying roller 4<reel shaft 45. FIG.

Back tension is applied to the ink ribbon in the ink ribbon cassette 8 to apply a load in the direction opposite to the conveying direction, and the ink ribbon is taken up by rotating the reel shaft 45 . Since the reel shaft 45 has a torque limiter inside, the ink ribbon can be wound with the ink ribbon always stretched.

FIG. 9 is a diagram illustrating a mechanism for supporting the cutting section 30 and the recording head 6 in the printer 1 according to the embodiment.

The recording head 6 is fixed to a recording head supporting member 49 having a head cam follower 43 shown in FIG. 9, and has a predetermined number of heating elements arranged in the Z direction of FIG.

Positional movement of the recording head 6 will be described with reference to FIGS. 3 and 4. FIG.

FIG. 3 is a diagram showing a nip position (hereinafter referred to as first position) where the recording head 6 contacts the platen roller 3 to form a nip in the printer 1 according to the embodiment.

Also, FIG. 4 is a diagram showing a retracted position (hereinafter referred to as a second position) where the recording head 6 is separated from the platen roller 3 and the nip is released in the printer 1 according to the embodiment.

The sub-motor 9 transmits drive to the head cam 42 via an idler gear (not described). As a result, the head cam 42 rotates, and the recording head support member 49 is moved by changing the position of the head cam follower 44 according to the rotation angle. The recording head support member 49 is always urged substantially upward along the Y-axis by the head spring 47 , and the head cam follower 44 is always urged in the direction of coming into contact with the head cam 42 . At the first position, as shown in FIG. 3, the recording head 6 is in contact with the platen roller 3 and the recording head supporting member 49 is stopped. In this state, the head cam follower 44 cannot follow the cam curved surface of the head cam 42 and the load of the head spring 47 can be transmitted to the platen roller 3 via the recording head 6 . As a result, the recording head 6 can contact the ink ribbon and transfer the ink to the recording medium. At the second position, the head cam follower 44 is pushed down by the cam surface of the head cam 42 as shown in FIG.

FIG. 10 is a diagram for explaining the head cam 42 that vertically moves the recording head support member 49 to control the movement of the recording head 6, as shown in FIGS.

Movement to the first position shown in FIG. 3 is performed by detecting a flag 51b formed on the head cam 42 shown in FIG. The sub-motor 9 is pulse-driven and controlled to stop.

In the movement to the second position shown in FIG. 4, similarly to the movement to the first position, the transmissive cam sensor 50 detects the flag 51a formed on the head cam 42 (light shielding→transmission). It is controlled by pulse-driving the sub-motor 9 and stopping it.

Next, the cutting portion 30 will be described with reference to FIG.

A cutter cam 41 that is coaxially coupled with the head cam 42 and rotates in the same direction contacts a cutter cam follower 43 of the cutting section 30 to move the cutting section 30 up and down. The cutting section 30 includes a cutter blade 48. When the driving of the sub-motor 9 is transmitted to the cutting section 30 and the cutting section 30 moves vertically (in the Y-axis direction), the cutter blade 48 comes into contact with the cutter blade receiving member 46 and cuts the tube. and labels are cut.

FIG. 11 is a perspective view of the cutter blade receiving member 46 of the cutting section 30 of the printer 1 according to the embodiment.

The cutter blade receiving member 46 has two surfaces, a full cut surface 46a which is a smooth surface and a half cut surface 46b which is a surface having a small concave shape in part. Half cutting or full cutting is possible by switching between these two surfaces during the cutting process. In the embodiment, the cutter blade receiving member 46 is covered with the thin plate 52 made of SUS material in order to form the half-cut surface 46b.

In the half-cutting operation, the half-cutting surface 46b of the cutter blade receiving member 46 is in a posture parallel to the X-axis direction by a mechanism (not described), and the cutter cam 41 is rotated in the CW (clockwise) direction as shown in FIG. By rotating, as shown in FIG. 7, the printing unit 30 is moved upward along the Y axis. The amount of movement of the cutting portion 30 is controlled such that the transmission type cam sensor 50 detects the flag 51b (FIG. 10) (light shielding→transmission), and after that detection, the sub motor 9 is pulse-driven for a predetermined number of times and stopped. . In this way, the recording medium is cut in half by the cutter blade 48 coming into contact with the half-cut surface 46b.

The full cutting operation will be described, for example, in a case where it is performed from the recordable state shown in FIG. Rotate to the cam 41 position. While the cutter cam 41 is rotating in the CCW direction, the cutter blade receiving member 46 assumes a posture in which the entire cut surface 46a is parallel to the X-axis direction by a mechanism (not described). Furthermore, after that, the recording unit 30 is moved upward along the Y axis. The amount of movement of the cutting portion 30 is controlled such that the transmission type cam sensor 50 detects the flag 51a (transmission→light shielding), and after that detection, the sub motor 9 is pulse-driven for a predetermined number of times and stopped. The cutter blade 48 completely cuts the recording medium by coming into contact with the full cut surface 46a.

Here, the operation during recording of the printer 1 according to the embodiment will be described with reference to FIGS. 5 to 10. FIG.

FIG. 5 is a diagram showing a state in which the recording head 6 is at the second position and the cutting section 30 is at the retracted position in the printer 1 according to the embodiment. In the printer 1 according to the embodiment, this is the state when the power is turned off/on, or when the recording medium is ejected. At this time, the latch member 60 attached to the recording head support member 49 is engaged with the reel shaft 45 . Here, a torque limiter (FIG. 17) is provided inside the reel shaft 45, and the rotational drive of the main motor 5 is transmitted through the drive transmission gear (FIG. 17) and the torque limiter (FIG. 17) to the reel shaft. 45 to take up the ink ribbon. Therefore, when the main motor 5 is driven to rotate in the state shown in FIG. However, since the reel shaft 45 of the ink ribbon take-up reel is engaged with the latch member 60 attached to the recording head support member 49, the rotation of the reel shaft 45 is restricted and does not rotate. As a result, the recording medium can be conveyed while the ribbon winding drive is stopped.

Next, the recording operation and cutting operation will be described. As shown in FIG. 5, the sub-motor 9 is driven so that the head cam 42 rotates in the CW direction. After that, when the flag 51 of the head cam 42 is detected by the cam sensor 50 (FIG. 9), the sub motor 9 is pulse-driven a predetermined number of times and then stopped. As a result, the state shown in FIG. 6 is obtained.

FIG. 6 is a diagram showing a state where the recording head 6 is at the nip position (first position) and the cutting section 30 is at the retracted position. In this state, recording is performed while the recording medium is transported by transport means to which the rotational drive of the main motor 5 is transmitted.

In this way, when the recording medium on which one page has been recorded reaches the recording medium cut position from the recording position shown in FIG. 2, the half-cutting operation is performed for each recorded page to manufacture a product.

Then, for the final page, the cutting section 30 performs the above-described full cutting operation. At this time, when the recording medium is conveyed to the cut position after the last page has been recorded, the recording head 6 is controlled to move to the retracted position (second position) as shown in FIG. As described above, when the main motor 5 is driven in the state shown in FIG. 5, the drive is transmitted to the platen roller 3 and the transport roller 4. It will be in a state of meshing with. Therefore, the recording medium is conveyed while the ink ribbon winding drive is stopped. As a result, it is possible to prevent the ink ribbon from being excessively wound up, thereby reducing waste of the ink ribbon.

FIG. 12 is a block diagram illustrating the configuration of the controller 1200 of the printer 1 according to the embodiment.

The control unit 1200 is connected to the main motor 5 , the sub motor 9 , the cam sensor 50 , the tube detection sensors 1205 , the operation unit 13 and the display unit 14 , and controls the main motor 5 and the sub motor based on the inputs from the sensors and the input unit 13 . 9 and the display unit 14 are controlled. The control unit 1200 includes a ROM 1202 that stores a print control program and the like executed by the CPU 1201 and a RAM 1203 that stores various data and the like input by the input unit 13 . The RAM 1203 includes a print data storage area for storing print data, a setting information area for storing various setting information such as print medium type, size, print density, and cut information, and a data expansion area for expanding print data. , and other areas. An external terminal such as a personal computer (not shown) can be connected to the printer 1 via the USB I/F 1204, and print data from the external terminal can be printed by the printer 1. FIG.

FIG. 13 is a flowchart for explaining recording (printing) processing by the printer 1 according to the embodiment. The processing shown in this flowchart is implemented by the CPU 1201 executing a program stored in the ROM 1202 .

First, in S 1301 , the CPU 1201 rotates the sub motor 9 to rotate the head cam 42 to move the recording head support member 49 to the first position where the recording head 6 contacts the platen roller 3 . As a result, the recording head 6 comes into contact with the ink ribbon so that the ink can be transferred to the recording medium. Next, in S1302, the CPU 1201 drives the main motor 5 to convey the print medium, and in S1303 drives the print head 6 according to the print data to print. Then, in S1304, the CPU 1201 determines whether or not there is print data. In S1304, the CPU 1201 proceeds to S1305 when there is no next print data.

In S<b>1305 , the CPU 1201 rotates the sub motor 9 to rotate the head cam 42 to move the recording head support member 49 to the second position where the recording head 6 is separated from the platen roller 3 . Then, the CPU 1201 advances to S1306 and causes the printed printing medium to be conveyed. In S1307, when the printed recording medium reaches the cutting section 30, the rotation of the main motor 5 is stopped and the rotation of the conveying roller is stopped. Then, the cutting unit 30 is driven to cut and discharge the recording medium.

In the flowchart of FIG. 13, the recording head remains at the first position when printing is started, and is moved to the second position away from the platen roller 3 when printing is finished. Therefore, during this period, the ink ribbon is transported and consumed as the recording medium is transported. Therefore, in order to further reduce the waste of the ink ribbon, the recording head may be moved to the second position away from the platen roller 3 when the blank area continues for a predetermined amount or more.

14 is an enlarged view of the latch member 60. FIG.

This latch member 60 is provided with a boss and an elongated hole for attachment to the recording head support member 49 .

15A and 15B are diagrams illustrating an assembly structure of the latch member 60 to the recording head support member 49. FIG.

The recording head support member 49 is also provided with bosses and elongated holes corresponding to the bosses and elongated holes of the latch member 60. These bosses and elongated holes are fitted with the bosses and elongated holes of the latch member 60, and are secured by E-rings. fixed. Here, the latch member 60 is urged by a spring in a direction to press the latch member 60 against a latch gear (FIG. 17), which will be described later, and is movable within the range of the elongated hole.

FIG. 16A is a diagram showing the position of the latch member when no pressing force is applied to the latch member 60. FIG.

FIG. 16(B) is a diagram showing a state in which the latch member 60 in the state of FIG. 16(A) is pressed upward. 16, the latch member 60 moves upward and stops at the position where the slot contacts the boss. When the upward bias is released from this state, the state shown in FIG. 16A is restored by the biasing force of the spring.

17A and 17B are diagrams for explaining the configuration of the reel shaft 45 for driving the reel on which the ink ribbon stored in the ink ribbon cassette 8 is wound in the printer 1 according to the embodiment.

FIG. 18 is a diagram showing the configuration of the ink ribbon cassette 8 according to the embodiment.

A ribbon reel on the sending side and a ribbon reel on the winding side are housed inside the ink ribbon cassette 8, and the ink ribbon sent from the ribbon reel on the sending side is wound on the ribbon reel on the winding side. The portion where the ink ribbon is exposed to the outside corresponds to the position of the recording section when the printer 1 is set.

When the ink ribbon cassette 8 is set in the printer 1, the reel shaft 45 shown in FIG. 17 fits into the hole provided in the center of the take-up ribbon reel. By rotating the reel shaft 45, the ink ribbon is taken up by the take-up ribbon reel and transported. Note that the ink ribbon advances only in one direction, and is not conveyed in the opposite direction. A ratchet mechanism may be provided on the reel in order to suppress the transport in the reverse direction.

In FIG. 17, the member of the reel shaft 45 that drives the take-up ribbon reel is provided with a latch gear that meshes with the latch member described above. Also, the reel shaft 45 receives driving force from a drive transmission gear via a torque limiter. Since the torque limiter is provided between the reel shafts 45 in this manner, the torque limiter rotates idle when the torque applied to the reel shaft 45 exceeds a predetermined value. This prevents the reel shaft 45 from being forced to rotate and cutting the ink ribbon.

FIG. 5 is a diagram showing a state when recording is not performed. When the recording head 6 pointed to the recording head supporting member 49 is set to the retracted position, the same recording head supporting member 49 is pointed. The latch member 60 is in a position to engage and mesh with the latch gear of the reel shaft 45 . When the main motor 5 is rotationally driven in this state, power is transmitted to the drive transmission gear while the rotation of the reel shaft 45 is stopped by the latch member 60, so that the torque limiter idles. Therefore, even if the recording medium is conveyed by driving the main motor 5 when recording is not performed (when the recording head 6 is at the retracted position (second position)), the reel shaft 45 cannot rotate. The ink ribbon is not wound up.

On the other hand, FIG. 6 shows the state during printing. When the printing head 6 is moved to the printing position, the latch member 60 is separated from the latch gear. When recording is performed while conveying the recording medium in this state, the reel shaft 45 receives power from the drive transmission gear and rotates to wind up the ink ribbon.

The reason why the latch member 60 can move by fitting the boss and the elongated hole is that when the latch member 60 and the latch gear are moved from the state in which the latch member 60 and the latch gear are separated to the state in which the latch member 60 and the latch gear are engaged, the latch gear Depending on the position (phase) of , there is a possibility that the ridges of the gear of the latch member 60 and the ridges of the latch gear come into contact with each other. In such a case, by configuring the latch member 60 to move away from the latch gear, excessive pressing force is not applied to the latch member 60 and the latch gear. When the ridges of the gears abut against each other, the latch gear rotates as the drive transmission gear rotates, and the urging force of the spring engages the ridges and troughs of the gears, causing the torque limiter to idle.

As described above, according to the embodiment, it is possible to reduce the waste of the ink ribbon without increasing the cost or increasing the size of the apparatus due to newly providing a motor, an actuator, or the like.
