[Conventional technology]

As a kind of color dot recorder, the applicant of this invention filed a patent application in 1983-39248. There is a ``color recording device'' filed as a patent application. 3 and 5 are diagrams schematically illustrating the configuration of such a color recording apparatus. this In the figures, 10 is a platen around which a recording paper 20 is wound, for example, a step It is rotated at a predetermined speed by a motor and gears. 30 is the recording head, e.g. For example, movement constituted by a step motor 11, a pulley 12, and a reeling line 13. The recording paper 20 is moved back and forth by a mechanism in a direction perpendicular to the feeding direction of the recording paper 20.

0003 FIG. 4 is an explanatory diagram showing a main part of a specific example of such a recording head 30. As shown in FIG. Note that the recording head 30 is formed of a main body and a cover, but these are shown in FIG. It is shown by a two-dot chain line as being superimposed and integrated. In Figure 4, the main body A bearing 31 is provided near one end, and a coil spring 32 is connected to the bearing 31. A wire hammer 33 is inserted so as to be vertically displaceable, and a yoke 34 is provided near the other end. At the same time, a coil 35 and an armature 36 are stacked on the yoke 34. The layers are arranged to form a magnetic circuit. 37 is attached to the inner surface of the cover. - A leaf spring that acts as a spring for the armature 36, and the free end is the armature. It is attached to the end surface of the yoke 34 via a yoke 36 so as to be substantially opposed to it. The armature 36 has a middle part on the inner surface of the cover. It fits into a guide 38 formed to be vertically displaceable and has one end. The end of the wire hammer 33 is pressed, and the other end is pressed by the leaf spring 37 to release the yoke 3. 4 and the coil 35. And the leaf spring of the cover A protrusion 39 is provided on the inner surface near the leaf spring 37 so as to protrude beyond the free end of the leaf spring 37. At the same time, a projection 39 is provided near the end of the armature 36 on the leaf spring 37 side. A fitting hole 40 is provided, and the cover has a plate spring 37 and an armature 36. It can be attached by stacking it on the main body with the attached. This results in The recording head 30 is configured as shown in FIG. 4, and the armature 36 is The contact part with the yoke 34 and the leaf spring 37 is rotated depending on whether the coil 35 is excited or not. The wire hammer 33 is rotated and displaced around the center, and the wire hammer 33 is selectively displaced in a substantially vertical direction. It turns out. Note that 41 indicates the direction in which the recording head 30 is perpendicular to the feeding direction of the recording paper 20. This is a guide shaft that guides the user in the direction of the object.

Again in FIGS. 3 and 5, reference numeral 50 denotes an endless color ink ribbon that is dyed in multiple colors C ₁ to C ₆ in the width direction, and is inked at a constant rate while facing the effective recording width of the recording paper 20 . The ink ribbon is housed in an ink ribbon cassette 51 so as to be movable in this direction. The ink ribbon cassette 51 is attached to a cassette holder 52 which is swingably attached to the upper part between the left and right side plates 61 and 62 on the front surface of the apparatus main body via mounting shafts 63 and 64, and is attached to the front surface of the apparatus main body via a leaf spring 53. It is removably attached. This cassette holder 52 is rotationally driven in a reciprocating direction by, for example, a motor 65 and a sector gear 66. As a result, the ink ribbon 50 is swung about the mounting shafts 63 and 64 of the cassette holder 52 along the feeding direction of the recording paper 20. Furthermore, an ink ribbon winding mechanism consisting of a motor 54 and a gear train 55 for winding up the color ink ribbon 50 is attached to the back of the cassette holder 52.

[0005] The recording operation of the apparatus configured as described above will be explained. First, by turning on the power, the recording head 30 is temporarily moved to the 0% side (toward the left). A reference position signal generator that moves and is composed of, for example, a lever 56 and a photosensor 57. The mechanism is driven to generate a reference position signal and to stop at the reference position. on the other hand, The cassette holder 52 is also rotated to the reference position, for example, the lever 58 and the photo sensor 5 When a reference position signal is generated by driving the reference position signal generation mechanism consisting of Both stop at the reference position. As a result, the recording head 30 and the ink ribbon 5 Initialization to 0 will be performed.

[0006] Next, the color band of the first channel of the ink ribbon 50 directly faces the wire hammer 33. The cassette holder 52 is rotated by a predetermined angle from the reference position so as to rotate. this After rotating the cassette holder 52 by a predetermined angle from the reference position in this manner, the recording Move the recording head 30 from the reference position (0%) toward the 100% side at a constant speed. let Then, the recording head 30 reaches the recording position of the first channel during the movement. As a result, the recording head 30 is stopped, and the coil 35 is selectively energized, causing the recording head to stop. A dot recording operation by the hammer 33 is performed. As a result, the recording paper 30 has the first The magnitude of the measurement signal of the first channel is displayed in the predetermined color assigned to the channel. will be recorded as a cut. When the dot recording is finished, the recording head 30 is at the 100% position. Move to and stop. With the recording head 30 stopped at the 100% position, so that the color band of the second channel of the ink ribbon 50 directly faces the wire hammer 33. The cassette holder 52 is rotated through a predetermined angle from the position of the first channel. child Rotate the cassette holder 52 at a predetermined angle from the first channel position as shown below. After moving, move the recording head 30 from the 100% position toward the 0% side at a constant speed. move it. Then, while the recording head 30 is moving, the recording position of the second channel is The recording head 30 stops by reaching the point, and the coil 35 is selectively energized. Then, the wire hammer 33 performs a dot recording operation. As a result, the recording paper 20 indicates the magnitude of the measurement signal of the second channel with a predetermined color assigned to the second channel. The dots will be recorded. When the RBI recording is finished, the recording head 30 is at 0%. Move to the position and stop. After that, repeat the same operation as many times as the number of color bands on the ink ribbon 50 to create multiple channels. A dot pattern of a predetermined color assigned to each channel record in analog mode.

[0007] By the way, in such a conventional configuration, the motor 5 is mounted on the back of the cassette holder 52. 4 and a gear train 55, which is equipped with an ink ribbon winding mechanism. The load on the mechanism that swings the cassette holder 52 becomes heavy, and the motor 65 has a high torque. I had to use one from Luxury, and it ended up being large. In addition, when the cassette holder 52 swings, an ink ribbon winding mechanism is also used. Because they oscillate at the same time, additional oscillating space is required, making the entire device smaller. become an obstacle for

[0008] Therefore, in order to solve such problems, the applicant of the present invention filed Utility Application No. 62-92358. The ink ribbon winding mechanism and cassette holder swinging mechanism are driven by a common motor. We are applying for a device that is designed to operate. Figure 6 explains the principle of the main parts of such a prior application. 5, the same parts as in FIG. 5 are given the same reference numerals. In the figure, 81 is in This is a bracket to which the ribbon winding mechanism is attached, and the cassette holder 5 It is attached to the back of 2. 82 rotates in conjunction with the rotation of the sector gear 66. This gear is attached to one end of the shaft 83. The shaft 83 is attached to the bracket 81 It is rotatably attached, and a bevel gear 84 is attached to the other end. There is. This bevel gear 84 is attached to one end of a shaft 85 that passes through the bracket 81. It is meshed with a bevel gear 86 attached thereto. The middle part of the shaft 85 can be rotated. A plate 87 is loosely fitted to the other end, and a gear 89 is connected to the other end via a compression spring 88. installed. A gear 90 that meshes with a gear 89 is rotatable on the plate 87. This gear 90 functions as a planet gear. gear 91 is attached to one end of a shaft (not shown) passing through the bracket 81 and the cassette holder 52. The other end of this shaft is connected to the ink ribbon take-up shaft of the ink ribbon cassette 51. connected. Gears 92 and 93 are meshed with this gear 91, A gear 94 is meshed with the gear 93. These gears 92 to 94 are It is rotatably attached to the port 81.

[0009] In such a configuration, the cassette holder 52 can be swung in the direction A1. The gear 89 rotates in the direction B1, and the plate 87 is rotated by the flick of the spring 88. rotationally moves upward as indicated by C1. As a result, gear 90 becomes gear 9 4, and the gear 91 is driven to rotate in the same direction as the gear 89. On the other hand, As the cassette holder 52 is swung in the direction of A2, the gear 89 is moved in the direction of B2. The plate 87 rotates downward as shown by C2 due to the friction of the spring 88. Rotate and move in the direction. As a result, the gear 90 meshes with the gear 92, and the gear 91 meshes with the gear 92. 89. As a result, the ink ribbon take-up shaft of the ink ribbon cassette 51 is moved to the cassette holder. Regardless of the direction in which the rotor 52 swings, it is always rotated in a constant direction.

[Problem that the idea aims to solve]

0010 However, when focusing on the rotational momentum transmitted from gear 82 to gear 91, gear 8 2 is transmitted to gear 89 via bevel gear 84 and bevel gear 86. , the rotation of this gear 89 provides friction that rotates the plate 87. The rotation that is finally transmitted to gear 91 is transmitted to gear 91 by The amount of momentum will be considerably smaller. In addition, regardless of the direction in which the cassette holder 52 swings, the winding direction of the ink ribbon can be adjusted. The vertical movement of the plate 87 in the same direction is the deceleration rotation output of the bevel gear 86. This is done by the friction of the spring 88 that is generated based on the When the direction is switched, the winding operation of the ink ribbon is temporarily stopped. For these reasons, according to the conventional configuration, the amount of feed of the ink ribbon 50 becomes small. The wire hammer 33 may hit adjacent parts of the ink ribbon 50 continuously. The number of ink ribbons is 50, especially when recording patterns such as character symbols. There is a problem that the lifespan is shortened. This invention focuses on these problems, and its purpose is to develop an ink ribbon. The goal is to realize a color dot recorder that can take up a relatively large amount of winding material. Ru.

[0011]

[Means to solve the problem]

The present invention that achieves these objectives is An endless ink ribbon dyed in multiple colors in the width direction makes effective recording on the recording paper. The ink ribbon cassette is stored in a stretched state facing the recording width. If you swing the cassette holder to be removed back and forth along the recording paper feeding direction, The ink ribbon is wound in a fixed direction and moved along the width of the recording paper. Color dot recorder that records color dots using wire hammers that are arranged so that -In Da, A motor that can rotate in any direction, a swinging mechanism that swings the cassette holder according to the rotation of the motor; It is set so that the load is greater than this swing mechanism, and one of the motors a winding mechanism that winds up the ink ribbon according to the rotation in the direction; A brake that engages a part of the swinging mechanism to prevent swinging during the ink ribbon winding operation. -Ki mechanism, It is characterized by being composed of.

0012

[Effect]

When the swing mechanism is not braked, the ink ribbon winding mechanism is Since the load is larger than the load on the swing mechanism, the swing of the cassette holder is caused by the rotation of the motor. This is done depending on the direction of rotation. When winding the ink ribbon, a brake is temporarily applied to the swing mechanism. The load on the swing mechanism is temporarily larger than the load on the ink ribbon winding mechanism. By doing so, the ribbon winding mechanism is rotationally driven. This allows the ink ribbon feed amount to be set arbitrarily.

【Example】

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a configuration explanatory diagram showing an embodiment of the present invention. In the figure, 101 is the side plate. cassette holder 102 is rotatably mounted via shaft 103 and , a motor 104 that can rotate in any direction is attached. This motor 104 The rotational output is attached to the shaft 103 via gears 105, 106, 107 attached to the side plate 101. The signal is transmitted to gear 108, which is turned off. The rotation of gear 108 is controlled by one side of cassette holder 102. It is transmitted to gear 111 via gears 109, 110 attached to the side. cassette phone The lower edge of one side of the slider 102 is formed in an arc shape, and the lower edge of the slider 102 swings along the arc near the outer periphery. A plurality of slits 112 are provided at equal intervals according to the pitch of the movement, and part of the side surface of this slit is Shutter of photosensor 113 attached to side plate 101 to control movement angle The arm 114, which functions as an L-shape, is bent. 115 is also a photo sensor and is attached to the side plate 101 so as to detect the slit 112. 116 is It is a brake disc and is attached to the shaft 103 together with the gear 108. 117 is a brake that selectively clamps both sides of the brake disc 116, for example, Driven by Noid 118. 119 is a strut that regulates the swing range of the cassette holder 102. and is attached to the side plate 102. 120 is the ink ribbon winding shaft and is attached to the cassette holder 102. FIG. 2 is an explanatory diagram of the configuration around the ink ribbon winding mechanism of FIG. 1. Axis 121 Gear 111 is attached to one end and bevel gear 122 is attached to the other end. . This bevel gear 122 is a bevel gear 123 attached to the end of the winding shaft 120. are interlocked with. The load on this ink ribbon winding mechanism is the rocker. The load is set higher than the load on the system.

[0014] The operation of the configuration shown in FIG. 1 will be explained. Since each gear is always meshed, the rotation of motor 104 is transmitted to gear 108. It is also transmitted to gear 111. Bevel gear 122 is attached to gear 111. This bevel gear 122 is attached to the ink ribbon take-up shaft 120. It is meshed with Belgia 123. Here, the cassette holder 102 is rotated. The load for this is when brake 117 is not holding brake disc 116. Gear 108 is designed to be smaller than the load for winding the ink ribbon. moves while meshing with the outer circumference of gear 109, and the cassette moves according to the rotation of motor 104. The holder 102 will start rotating.

[0015] For example, immediately after turning on the power, the cassette holder 102 rotates the motor 104 in the A direction. Rotate in the direction of rotation. Cassette holder 102 is arm 114 is photo sensor 113 After crossing over and detecting the origin position, it comes into contact with pin 119. Photo sensor 113 to a - Based on the output signal of photo sensor 115 at the time when the passing detection signal of frame 114 is output. Next, set the reference position of the slit 112, and then set the desired color of the ink ribbon 50. The output signal of photo sensor 115 when the corresponding number of slits is given as the target value. Control according to increase and decrease. Then, when the set angle is reached, solenoid 118 is actuated. The brake 117 is operated and the brake disc 116 is clamped to rotate the shaft 103. This prevents the cassette holder 102 from swinging. This allows the wire hammer to 33 faces the desired color of the ink ribbon 50.

[0016] In this way, with the shaft 103 prevented from rotating, the motor 104 is rotated to wind the ink ribbon. The rotation of gear 108 is transmitted to gear 111, and the incremental Rotate the ribbon winding shaft 120 in the direction of winding the ink ribbon. At this time, - The feeding amount of the ink ribbon 50 can be arbitrarily controlled by controlling the rotational speed of the printer 104. Can be set. After feeding the ink ribbon 50 by a predetermined amount, release the brake and reload the cassette. Rotate the cutter holder 102. Thereafter, similar operations are repeated.

[0017] With this configuration, the rotational speed of the motor 104 is increased to increase the rotation speed of the ink ribbon. By increasing the feed amount of 50, the frequency of consecutive dot recording can be reduced. Therefore, the life of the ink ribbon 50 can be extended. In addition, the color selection operation of the ink ribbon 50 by the swinging of the cassette holder 102 is Based on the output signal of the sensor 115, the movement can be quickly performed in the near direction of front and back. In addition, the home position detection operation is not limited to only when the power is turned on, but can be performed as necessary. This may be done as appropriate.

[0018]

[Effect of the idea]

As explained above, according to the present invention, a common motor is used to swing the cassette holder. and winding of the ink ribbon can be performed separately. A color dot recorder that can handle a relatively large amount of data can be realized.
