In the columns (a) to (e) of Fig. 22 and Fig. 23, the case where the first weir 100a is attached to the seat portion 200 is shown in stages. In addition, in FIGS. 22 and 23, the illustration of the first side wall portion 204 of the holder portion 200 is omitted for the sake of convenience. In addition, in FIGS. 22 and 23, an arrow CP indicating the position at which the holder portion 200 comes into contact with the first weir 100a is appropriately illustrated. In addition, the mounting process of attaching the second weir 100b to the seat portion 200 is substantially the same as that of the first weir 100a, and therefore the illustration and description thereof are omitted.

In the first stage (column (a) of FIG. 22), the first side 100a approaches the holder portion 200 in a state where the third wall portion 103 side is inclined downward. Then, the upper end portion of the third wall portion 103 is in contact with the upper end portion of the rear wall portion 203 of the holder portion 200, and the fifth wall portion 105 and the sixth wall portion 106 are The lower end of the first rib 141 at the rear end portion is in contact with the upper end portion of the first sub-wall portion 221 .

In the second stage (column (b) of FIG. 22), the first 匣100a is a contact point between the upper end portion of the rear wall portion 203 of the seat portion 200 and the upper end portion of the third wall portion 103 of the first cymbal 100a. As a fulcrum, move backwards (arrow RD). At this time, the lower end of the first rib 141 moves while sliding on the upper surface of the inclined portion 225 of the first sub-wall portion 221 . Further, the lower end of the second rib 142 is in contact with the upper end of the notch portion 226 of the first sub-wall portion 221 .

In the third stage (column (c) of FIG. 23), the main engaging portion 120 of the first weir 100a is in contact with the crossbar portion 230 of the seat portion 200. More specifically, the first side wall portion 125 of the main engagement portion 120 and the end surface 127 on the front side of the second side wall portion 126 are in surface contact with the end surface 237 of the flat plate portion 236 of the bridge portion 232 of the crossbar portion 230. Further, a plurality of projections 114 provided at the lower end of the third wall portion 103 of the first weir 100a are inserted into the corresponding fitting holes 227 of the holder portion 200. Thereafter, the first weir 100a is rotationally moved with the contact point of the projection 114 and the fitting hole 227 as a fulcrum.

In the fourth stage (column (d) of FIG. 23), the main engagement portion 120 is moved downward by the rotation of the first cymbal 100a. The crossbar portion 230 is pressed by the first side wall portion 125 and the second side wall portion 126 of the main engagement portion 120, and is rotated forward toward the direction away from the main engagement portion 120 (arrow SD). In addition, in the present specification, when referring to "moving in the direction of leaving", it includes not only the case of moving away from the object actually, but also the state of being oriented toward the object while maintaining the distance from the object. The situation in which the object moves in the opposite direction.

In the first step 100a of the present embodiment, since the crossbar portion 230 is swung by the pressing of the main engaging portion 120, the rotational movement operation of the crossbar portion 230 by the user's fingertip can be omitted. In particular, in the present embodiment, the crossbar portion 230 is pressed by the first side wall portion 125 of the main engagement portion 120 and the second side wall portion 126 at two points spaced apart in the direction of the arrow X. Therefore, the crossbar portion 230 can stably perform the rotational movement in a state where the inclination with respect to the direction of the arrow X is suppressed.

Further, in the fourth stage, the contact portion CP (FIG. 17) of each of the terminals 151 to 159 in the terminal portion 131 of the circuit board 130 of the first electrode 100a and the device-side terminal portion 250 of the holder portion 200 are each Terminals 261~269 (Fig. 9) are in contact. With the downward movement of the first crucible 100a, the surfaces of the contact portions CP of the terminals 151 to 159 of the circuit board 130 of the first crucible 100a are slidably rubbed by the respective terminals 261 to 269 of the holder portion 200. By "sliding friction" is meant relatively moving in the direction in which friction occurs.

By the sliding friction, the deposits on the surfaces of the terminals CP 151 to 159 of the circuit board 130 and the terminals 261 to 269 of the device-side terminal portion 250 can be removed, so that the terminals can be improved. Contactability. In particular, in the present embodiment, each of the terminals 261 to 269 of the device-side terminal portion 250 is in contact with the contact portion CP of each of the terminals 151 to 159 of the circuit board 130, so that it can be improved with respect to the circuit board 130. The sliding friction force of the contact portion CP of each of the terminals 151 to 159.

In the fifth stage (column (e) of FIG. 23), the rotational movement of the first weir 100a is completed, and the first wall portion 101 is supported by the bottom wall portion 201 of the seat portion 200. At this time, the lower end of the second rib 142 reaches the lower end of the notch portion 226 of the first sub-wall portion 221 and is fixed in position. The plurality of projections 114 provided at the lower end of the third wall portion 103 of the first crucible 100a are in a state of being inserted into the corresponding fitting holes 227 of the holder portion 200, and the first crucible 100a is locked to the holder. The engaging portion of the unit 200 functions.

Further, in the fifth stage, the first engagement portion 120 is moved to the lowest position, and the first side wall portion 125 of the main engagement portion 120 and the bridge portion 232 of the second side wall portion 126 and the crossbar portion 230 are released. The card between them. Therefore, the crossbar portion 230 is returned to the initial position (arrow RVD) on the rear side by the push mechanism 239 (FIG. 8) at the lower end portion thereof, and the bridge portion 232 is moved to the respective trunk portions 121 of the main engaging portion 120. Above 123. Thereby, the upper surfaces of the respective dam portions 121 and 123 are in surface contact with the lower surface of the flat plate portion 236 of the crossbar portion 230, and the main engaging portion 120 is engaged with the crossbar portion 230. After the above stage, the first crucible 100a is attached to the holder portion 200.

[Installation status of each part on the support part]

FIG. 24 is a schematic view for explaining the electrical connection between the engagement of the crossbar portion 230 and the device-side terminal portion 250. FIG. 24 schematically illustrates that the first side is mounted on the seat portion 200. The crossbar portion 230 at 100a, the main engaging portion 120, and the device side terminal portion 250. In FIG. 24, for the convenience of the device-side terminal portion 250, the arrangement state of the terminals 261 to 269 of the terminal portion front surface 251 is indicated by a broken line. The following description using FIG. 24 also applies to the mounting state in which the second jaw 100b is attached to the holder portion 200.

In the crossbar portion 230, the first and second leg portions 231a and 231b are supported by the first and second leg portions 231a and 231b in the same manner, and when the swinging movement is performed, the bridge portion 232 can be restrained from tilting with respect to the direction of the arrow X. . Therefore, the posture of the first jaw 100a in which the main engagement portion 120 is engaged is stabilized by the bridge portion 232. In particular, in the present embodiment, the bridge portion 232 of the crossbar portion 230 extends in the direction of the arrow X throughout the main engaging portion 120, so that the card of the main engaging portion 120 of the crossbar portion 230 can be improved. It is compatible, and the posture of the first 匣100a can be stabilized.

Further, in a state in which the first weir 100a is attached to the seat portion 200, the center of the main engaging portion 120 in the direction of the arrow X is located at substantially the same position as the center of the crossbar portion 230 in the direction of the arrow X. Therefore, it is possible to suppress the deviation in the direction of the arrow X in which the engaging force of the crossbar portion 230 with respect to the main engaging portion 120 is generated, and the stability of the posture of the first weir 100a can be further improved.

The rotation axis RX of the crossbar portion 230 is located near the lower end of the device side terminal portion 250. The distance between the bridge portion 232 in the direction of the arrow Z and the rotation axis RX is sufficiently longer than the distance between the bridge portion 232 and the lower ends of the terminals 261 to 269 of the device-side terminal portion 250. As described above, in the crossbar portion 230 of the present embodiment, the radius of the swivel of the bridge portion 232 can be sufficiently ensured. Therefore, the force of the bridge portion 232 given by the spring pushing mechanism 239 (FIG. 7 and FIG. 8) toward the main engaging portion 120 (the opposite direction of the arrow Y) is increased (the principle of the lever), and the use of the crossbar portion 230 can be improved. The engagement of the main engagement portion 120. Further, it is possible to reduce the force given by the user in order to rotate the crossbar portion 230 when the first jaw 100a is attached or detached. Further, since the distance (stroke) of the pivotal movement of the bridge portion 232 of the crossbar portion 230 can be ensured, the operational feeling of the user can be improved.

In the crossbar portion 230 of the present embodiment, two of the bridge portions 232 in the direction of the arrow X The distance WE between the ends is wider than the interval WT in the direction of the arrow X of the first and second terminals 261 and 262 located at both ends of the device-side terminal portion 250. The interval WT in the direction of the arrow X of the first and second terminals 261, 262 means the distance between the respective center lines. As described above, since the interval between the first and second terminals 261 and 262 is narrow with respect to the width of the bridge portion 232, even if the bridge portion 232 is inclined, the respective terminals 261 to 269 of the device-side terminal portion 250 can be reduced from the predetermined position. Position offset. Thereby, the connectivity of each of the terminals 261 to 269 of the device-side terminal portion 250 to the contact portion CP of each of the terminals 151 to 159 of the circuit board 130 can be improved.

In the present embodiment, in the state in which the first weir 100a is attached to the holder portion 200, the center of the crossbar portion 230 in the direction of the arrow X and the first and second terminals of the device-side terminal portion 250 are provided. The central locations of 261 and 262 are the same. Thereby, the positional shift of each of the terminals 261 to 269 in the device-side terminal portion 250 accompanying the inclination of the bridge portion 232 can be further suppressed.

Further, in the present embodiment, when the first crucible 100a is attached, the device-side terminal portion 250 is disposed at a position below the bridging portion 232. Therefore, when the crossbar portion 230 is engaged with the main engagement portion 120, the device side terminal portion 250 is pressed against the circuit board 130 from above. Therefore, the connection between the device-side terminal portion 250 and the circuit board 130 is improved by improving the engagement of the crossbar portion 230 with respect to the main engagement portion 120.

FIG. 25 is a schematic view for explaining the improvement of the space utilization efficiency by the crossbar portion 230. In FIG. 25, the state in which the crossbar portion 230 of the seat portion 200 and the main engaging portion 120 of the first weir 100a are engaged with each other is schematically illustrated by a side view. In addition, the following description using the first 匣100a of FIG. 25 is also applicable to the second 匣100b.

In the printing apparatus 10 of the present embodiment, the area EA occupied by the engaging mechanism including the crossbar portion 230 and the main engaging portion 120 and the area TA occupied by the electrical connection mechanism between the device side terminal portion 250 and the circuit board 130 are TA. It is approximately coincident in the height direction (the direction of the arrow Z). More specifically, the area EA occupied by the engaging mechanism includes the area TA occupied by the electrical connection mechanism. As described above, in the printing apparatus 10 of the present embodiment, the centralized arrangement is performed. The engagement mechanism and the electrical connection mechanism between the first jaw 100a and the holder unit 200 ensure a high utilization efficiency of the space in the printing apparatus 10.

Further, in order to obtain the effect based on the above-described lever principle in the crossbar portion 230, and also to secure the turning radius of the crossbar portion 230, it is not easy to reduce the range of the region EA occupied by the engaging mechanism in the height direction. Therefore, when the two regions EA and TA are configured to be separated in the height direction, the range occupied by the engagement mechanism and the electrical connection mechanism may increase, and the space efficiency may be lowered. In addition, the case where the two regions EA and TA are separated in the height direction includes a case where the two regions EA and TA overlap each other and are separated in the height direction. As described above, in the printing apparatus 10 of the present embodiment, the arrangement of the crossbar portion 230 and the device-side terminal portion 250 can improve the operability of the first crucible 100a and the utilization efficiency of the space in the device.

As described above, according to the holder portion 200 of the present embodiment, since the crossbar portion 230 is provided, the mountability of the first and second jaws 100a and 100b and the operability at the time of attachment and detachment thereof can be improved. Further, the space utilization efficiency of the mechanism for mounting the first and second cymbals 100a and 100b in the printing apparatus 10 can be improved.

B. Second embodiment:

The configuration of the crossbar portion 230s included in the holder portion 200s according to the second embodiment of the present invention will be described with reference to Figs. 26 to 28 . 26 to 28, a crossbar portion 230s which is attached to the front wall portion 202 of the holder portion 200s is illustrated. In Fig. 26, the crossbar portion 230s as viewed in the direction of the arrow Y is shown together with a portion of the front wall portion 202. In Fig. 27 and Fig. 28, a schematic cross section of the crossbar portion 230s or the front wall portion 202 when the C-C is cut and the D-D is cut as shown in Fig. 26 is shown. In Fig. 26, the attachment structure of the end portion of the second leg portion 231b of the crossbar portion 230s is selected in the nozzle. The holder portion 200s of the second embodiment is substantially the same as the configuration of the holder portion 200 of the first embodiment (FIGS. 4 to 6) except for the crossbar portion 230s. In the following description, the components that are the same as those in the first embodiment are denoted by the same reference numerals as those described in the first embodiment.

The crossbar portion 230s of the second embodiment has the first embodiment except that the first protruding portion 281a, the second protruding portion 281b, and the locking wall portion 285 are provided between the first and second leg portions 231a and 231b. The crossbar portion 230 of the form is substantially identical. The two protruding portions 281a and 281b are portions that protrude downward from the lower surface of the flat plate portion 236 of the bridge portion 232 (FIGS. 27 and 28). In the second embodiment, the two protruding portions 281a and 281b are configured as wall portions that extend at a uniform height in the direction of the arrow X.

The first protruding portion 281a and the second protruding portion 281b are provided apart from each other at both ends in the direction of the arrow X of the bridge portion 232, and are arranged on the same axis in the direction of the arrow X. The first protruding portion 281a is adjacent to the first leg portion 231a, and the second protruding portion 282b is adjacent to the second leg portion 231b. The first protruding portion 281a and the second protruding portion 281b are configured to be bilaterally symmetrical with respect to a center line in the direction of the arrow X of the crossbar portion 230s.

When the respective cymbals 100a and 100b are attached to the pedestal portion 200s, each of the first protruding portion 281a and the second protruding portion 281b abuts against the upper surface of the main engaging portion 120 of each of the cymbals 100a and 100b. Details of the functions of the first protruding portion 281a and the second protruding portion 281b will be described below.

The locking wall portion 285 is configured to be located further downward than the first protruding portion 281a and the second protruding portion 281b in the direction of the arrow Y, and protrudes downward from the first protruding portion 281a and the second protruding portion 281b. Wall. The locking wall portion 285 is formed between the first and second leg portions 231a and 231b. The locking wall portion 285 functions as a rotation restricting portion that restricts the movement of the crossbar portion 230s in the direction of approaching the crucibles 100a and 100b in a state in which the crucibles 100a and 100b are attached to the holder portion 200s (details) It is described below).

The locking wall portion 285 has first and second end portions 286a and a central portion 287. Each of the first and second end portions 286a and 286b is a substantially quadrangular shape formed at a position adjacent to the first and second leg portions 231a and 231b. The central portion 287 is a portion formed between the first and second end portions 286a and 286b, and has a uniform height (width in the direction of the arrow Z) in the direction of the arrow X. The first and second end portions 286a and 286b are respectively located at the center The 287 protrudes further downwards. In the crossbar portion 230s, since the height of the central portion 287 of the locking wall portion 285 is small, it is possible to suppress interference with the device-side terminal portion 250 disposed below the bridge portion 232 when the rotational movement is performed.

Here, the swivel movement of the crossbar portion 230s of the second embodiment is realized by the same mechanism as the crossbar portion 230 of the first embodiment (FIG. 28). The front wall portion 202 of the seat portion 200s has a fitting groove 290 in which an opening is formed in the direction of the arrow X. The crossbar portion 230s is rotatably attached to the abutment portion 200s by fitting a fitting groove 290 which is a recess corresponding to the convex portion 235 provided at each lower end of the first and second leg portions 231a and 231b.

The lower end of the first and second leg portions 231a and 231b of the crossbar portion 230s is formed with an inner convex portion 235s that protrudes in a direction opposite to the convex portion 235 that functions as a rotation axis (in the nozzle of FIG. 28). . The torsion spring that constitutes the push mechanism 239 that pushes the crossbar portion 230s in the rotational direction is attached to the inner convex portion 235s.

A restricting wall 291 (FIG. 26) for restricting the rotation of the second leg portion 231b toward the side of the weir receiving chamber 210 is formed in the front wall portion 202 of the seat portion 200s. By the regulating wall 291, the crossbar portion 230s is fixed to the initial position in a state of being pushed by the pushing mechanism 239 toward the side of the weir receiving chamber 210.

FIG. 29 is a schematic view for explaining the functions of the first protruding portion 281a, the second protruding portion 281b, and the locking wall portion 285 of the crossbar portion 230s. FIG. 29 shows a state in which the first weir 100a is attached to the seat portion 200s and the main engaging portion 120 is locked by the crossbar portion 230s. The same applies to the case where the second cymbal 100b is attached to the pedestal portion 200s.

As described above, when the first weir 100a is attached to the seat portion 200s, the first projecting portion 281a and the second projecting portion 281b of the crossbar portion 230s abut against the upper surface of the main engaging portion 120, respectively. In the holder portion 200s of the second embodiment, the main engagement portion 120 is formed to be pressed from above at two points spaced apart in the direction of the arrow X. Therefore, it is possible to suppress the main engaging portion 120 from being biased by the direction of the arrow X. Thereby, it is possible to suppress the first ink cartridge 100a from being inclined in the direction of the arrow X, and to fix the first ink cartridge 100a in a specific mounting state.

When the first ink cartridge 100a is attached to the holder portion 200s, the locking wall portion 285 is engaged with the main cartridge The end faces on the front side of the first weir portion 121 and the second weir portion 123 of the portion 120 are in contact with each other or approach each other. Further, the end portions 286a and 286b of the locking wall portion 285 are in contact with or close to the end faces of the front side of the first side wall portion 125 and the second side wall portion 126. With this, for example, even when the external force is applied to the crossbar portion 230s in the opposite direction of the arrow Y, the crossbar portion 230s is locked by the main engagement portion 120, and the excess is prevented from approaching the first ink cartridge 100a. Rotate the movement. Thereby, it is possible to suppress problems such as damage to the front wall portion 202 of the rail portion 230s or the seat portion 200s caused by the excessive rotational movement of the crossbar portion 230s.

As described above, according to the seat portion 200s of the second embodiment, since the rail portion 230s has the first projecting portion 281a and the second projecting portion 281b, the mounting and fixing properties of the respective jaws 100a and 100b can be improved. Moreover, since the crossbar portion 230s has the locking wall portion 285, the protection of the seat portion 200s when the first and second jaws 100a and 100b are attached can be improved.
