Description

  The present invention relates to a recording apparatus represented by a facsimile, a printer, and the like.

  Among printers, there is a so-called serial type in which printing is completed by alternately executing a sheet conveying operation of a predetermined amount and a recording operation accompanying the movement of a carriage having a recording head in the sheet width direction. . Further, in the ink jet type printer, there is a type in which the carriage is provided with the ink cartridge, and a type in which the ink cartridge is provided independently from the carriage and the ink cartridge and the carriage are connected by the ink tube. In any type of serial printer, recording is performed as the carriage reciprocates in a predetermined range.

  In recent years, there has been a demand for further miniaturization of printers. In the case of mobile type printers in particular where it is assumed that the user carries the printer, further miniaturization is required.

Here, focusing on the width dimension of the printer, the width dimension is generally determined by the width of the moving area of the carriage and the size and arrangement position of the components provided outside the moving area. Since the movement area of the carriage is determined by the sheet width and can not be made small, it is necessary to reduce the occupied space of the components provided outside the carriage movement area in order to reduce the width dimension.
Patent Document 1 discloses, as an example, a configuration in which an encoder scale is provided outside the carriage movement area.

  By the way, in the printer, in addition to the width dimension, it is also required to reduce the height dimension of the apparatus. However, if the height dimension of the apparatus is reduced, the volume of the carriage is reduced, and especially in the type where the carriage is provided with the ink cartridge, the ink cartridge has to be designed smaller. Therefore, in order to secure the carriage volume while reducing the height dimension of the device, it is necessary to increase the width of the carriage, and the width dimension of the device becomes large. That is, the carriage volume, that is, the capacity of the ink cartridge and the width dimension of the apparatus are in a trade-off relationship.

  Therefore, the present invention has been made in view of such a situation, and an object thereof is to provide a recording apparatus in which the width dimension of the apparatus is suppressed while securing the volume of the carriage.

The carriage in the state of being positioned at the end in the second direction, a support means for supporting the carriage, and a power transmission mechanism for transmitting the power of the drive source to the conveyance means for conveying the medium. Below, at least a part of the power transmission mechanism is located.

  According to this aspect, at least a portion of the power transmission mechanism is located below the carriage in the state of being moved to the end in the second direction, so that the motive power is within the area necessary for the carriage movement. The transmission mechanism is configured to be inserted, whereby the width dimension of the apparatus can be suppressed and the volume of the carriage can be secured.

  According to a second aspect of the present invention, in the first aspect, the carriage includes a protrusion projecting in the second direction, and the center of the supported region supported by the support means in the movement direction is the above-mentioned center. At least a part of the power transmission mechanism is located below the projection of the carriage in an asymmetric shape in the movement direction and in the state of movement to the end of the second direction. .

  According to this aspect, since the carriage includes the protrusion projecting in the second direction, the volume of the carriage can be secured by the protrusion and the carriage is moved to the end in the second direction. Since at least a part of the power transmission mechanism is located below the projection of the carriage, it is possible to suppress an increase in the lateral width dimension and the increase in the height dimension of the device.

  According to a third aspect of the present invention, in the second aspect, the carriage detachably includes an ink cartridge containing ink, and the ink cartridge occupies a space including the protrusion in the carriage. I assume.

  According to this aspect, since the ink cartridge containing the ink occupies the space including the projecting portion in the carriage, it is possible to secure the ink capacity in the ink cartridge.

  According to a fourth aspect of the present invention, in any one of the first to third aspects, the transport means is a first roller provided on the upstream side with respect to the recording head in the medium transport path, and the recording head A second roller provided on the downstream side, and the power transmission mechanism includes a first roller drive gear provided at an axial end of the first roller, and the first roller drive gear A rotary scale, which constitutes a rotation detection means for transmitting power to the second roller and detecting rotation of the first roller, is provided on the side of the first roller drive gear in the first direction It is characterized by

  According to this aspect, since the rotary scale is provided on the side of the first direction with respect to the first roller drive gear, the detection unit reading the rotary scale is the outermost side of the apparatus body (carriage movement It is possible to avoid the arrangement in the outside (in the direction), and to suppress the increase in the size of the apparatus body (the dimension in the carriage movement direction).

According to a fifth aspect of the present invention, in the fourth aspect, the diameter of the rotary scale is smaller than the diameter of the first roller drive gear.
According to this aspect, since the diameter of the rotary scale is smaller than the diameter of the first roller drive gear, the rotary scale can be protected from the external pressure from the upper side of the device.

  According to a sixth aspect of the present invention, in the fourth or fifth aspect, a frame supporting the first roller is provided, and the frame conforms to the outer shape of the rotary scale and is larger than the diameter of the rotary scale A convex portion forming an arc shape of a diameter is formed.

  According to this aspect, since the convex portion formed on the frame forms an arc shape along the outer shape of the rotary scale and having a diameter larger than the diameter of the rotary scale, the convex portion shields against the rotary scale It functions as a wall and suppresses the adhesion of ink mist to the rotary scale.

  According to a seventh aspect of the present invention, in the sixth aspect, the carriage is formed with a recess for avoiding the projection when the carriage is moved to the end in the second direction. I assume.

  According to this aspect, the carriage is formed with the concave portion for avoiding the convex portion formed on the frame when the carriage is positioned at the end in the second direction. It is not necessary to set the position of the frame to the outside (to prevent interference between the carriage and the frame) in order to ensure that the lateral dimension of the apparatus can be increased.

The endless belt 48 is stretched over the entire carriage movement area, operates with the power of the motor 47 (FIGS. 2 and 3), and moves the carriage 17.

  Next, the gear group 33 as a power transmission mechanism for transmitting the power of the motor 32 (FIGS. 15 and 16) to the conveyance drive roller 16 and the discharge drive roller 25 constituting the conveyance means for conveying the sheet P will be described. . The motor 32 is provided on the rear side in the apparatus longitudinal direction, and the gear group 33 includes the conveyance drive roller 16 located at the center in the apparatus longitudinal direction, and the discharge drive roller 25 located on the front side in the apparatus longitudinal direction A plurality of gears are provided to transmit power to the shaft 25a).

  Each gear which comprises the gear group 33 is provided in the side frame 10, and, in more detail, is provided in the outer side (apparatus outer side) of the side frame 10. As shown in FIG. The gear group 33 includes the gears 34, 35, 36, 37, 38, 39, 40, 41 in this order from the motor 32 side as shown in FIGS. The gear 34 is a gear provided on the rotation shaft of the motor 32, and the gear 37 is a gear (first roller drive gear) provided on the shaft end of the conveyance drive roller 16 as a first roller. These are gears (second roller drive gear) provided at the shaft end of the discharge drive roller 25 (the rotation shaft 25a thereof) as the second roller. The gear group 33 transmits power to the discharge drive roller 25 (its rotation shaft 25 a) via the gear 37.

  In addition to the gear 37, a rotary scale 45 is provided at the axial end of the conveyance drive roller 16 (FIGS. 13 and 14). The rotary scale 45 constitutes a rotation detection means 43 for detecting the rotation of the conveyance drive roller 16, and a detection unit 44 (FIG. 16) for detecting the rotation of the rotary scale 45 sandwiches the outer peripheral portion of the rotary scale 45. It is provided. The rotary scale 45 and the detection unit 44 constitute the rotation detection means 43, and the control unit (not shown) of the printer 1 rotates the conveyance drive roller 16 and the discharge drive roller 25 based on the detection signal from the rotation detection means 43. We can grasp quantity, direction of rotation.

In the above configuration, FIGS. 12 and 16 show the state where the carriage 17 is located at the end in the second direction. As illustrated, among the gears constituting the gear group 33, in the present embodiment, the gears 38 and 39 are generally located below the carriage 17, and a part of the gears 37 and 40 are below the carriage 17. Located in
Since at least a part of the gear group 33 is positioned under the carriage 17 in the state of being moved to the end in the second direction in this manner, the gear group 33 is inserted into the area necessary for the carriage 17 movement. It becomes a form and can restrain the width dimension of a device by this. In addition, since the width of the apparatus can be reduced even if the width of the carriage 17 is secured, the volume of the carriage 17, that is, the volumes of the ink cartridges 20A and 20B can be secured.

Further, in the present embodiment, since the carriage 17 is provided with the projecting portion 18f projecting in the second direction, the volume of the carriage 17 can be secured by the projecting portion 18f, and the carriage 17 is moved to the end in the second direction. Since at least a portion of the gear group 33 is located below the protrusion 18 f of the carriage 17, an increase in the width dimension of the device can be suppressed. Further, since the carriage volume can be secured without enlarging the carriage main body 18 in the height direction, an increase in the apparatus height dimension can also be suppressed.
Since the ink cartridge 20B occupies a space including the protrusion 18f in the carriage 17, the ink capacity in the ink cartridge 20B can be secured.

  Further, in the present embodiment, the rotary scale 45 constituting the rotation detection means 43 for detecting the rotation of the conveyance drive roller 16 as the first roller is the side in the first direction with respect to the gear 37 as the first roller drive gear ( It is provided on the side frame 10 side). Therefore, a detection unit 44 that reads the rotary scale 45 is also disposed between the gear group 33 and the side frame 10. Therefore, the detection unit 44 can be prevented from being disposed at the outermost side (outside in the carriage movement direction) of the apparatus body, and the increase in the size of the apparatus body (carriage movement direction size) can be suppressed.

  In addition, the rotary scale 45 is weak in strength, and a slight distortion easily reduces the detection accuracy, which tends to lead to the deterioration of the recording quality. However, in the present embodiment, since the rotary scale 45 is provided on the side in the first direction (the side of the side frame 10) with respect to the gear 37 as the first roller drive gear, the external pressure from the side of the device The scale 45 and the detection unit 44 can be protected.

  In addition, as shown in FIG. 13, the side frame 10 supporting the transport driving roller 16 is formed with a convex portion 10 a which follows the outer shape of the rotary scale 45 and forms an arc shape having a diameter larger than the diameter of the rotary scale 45. Accordingly, the convex portion 10 a functions as a shielding wall with respect to the rotary scale 45, and the adhesion of the ink mist to the rotary scale 45 can be suppressed.

  The carriage main body 18 is formed with a recess 18j which avoids the projection 10a when the carriage 17 is positioned at the end in the second direction (FIG. 11). That is, when the carriage 17 is positioned at the end in the second direction (the state of FIG. 12), the convex portion 10a enters the concave portion 18j. As a result, there is no need to set the position of the side frame 10 outside (to prevent interference between the carriage main body 18 and the side frame 10) in order to secure the movement area of the carriage 17 and to suppress the increase in the width of the apparatus. be able to.

  It goes without saying that the embodiment described above is an example, and the present invention is not limited to the above embodiment. For example, FIG. 17A is a view schematically showing the embodiment described above, and when the carriage body 18 is moved in the arrow direction from the position shown by the two-dot chain line, the gear 37 is at the most end. It enters completely below the carriage body 18 in the carriage movement direction (x direction). However, the present invention is not limited to such a configuration, and as shown in FIG. 17B, it is configured such that a part of the gear (37 ') enters the lower side of the carriage body 18 in the carriage movement direction (x direction). Also good. The broken line indicated by reference symbol Ln is the position of the left side surface of the carriage main body 18. Further, reference numeral 18m is a concave portion formed on the lower left side of the carriage body 18. The recess 18 m is a recess formed below the protrusion 18 f by the protrusion 18 f described above.

  Further, the carriage body 18 ′ shown in FIG. 18 has a symmetrical shape in the carriage movement direction (x direction) unlike the embodiment described above. That is, the recess 18 m and the recess 18 n on the opposite side are formed in the same size. When the carriage main body 18 'having such a shape is located at the end in the moving direction, the gear 37 may be configured to enter the recess 18m.
