[0039] The battery housing 401 has a front side surface 403 located at the front and a pair of vertical rear side surfaces 40 at the rear. 5. A pair of inclined rear side surfaces 407 and hook receiving side surfaces 419 (corresponding to the "surface-shaped protrusion" of the present invention) (To be done.) Left side 409 on the left, right side 411 on the right, rear side 413 on the back It is surrounded by a battery enclosure surface that includes [the battery].

[0040] Here, the front side surface 403 corresponds to the "first side surface" as referred to in this invention. Also, a pair of vertical rear The entirety or part of side 405, the pair of inclined rear side 407 and hook receiving side 419 is this This corresponds to the "second side" as referred to in the invention. Furthermore, the hook receiving side 419 corresponds to the " This corresponds to the "protrusion on the surface". Furthermore, the battery housing 401 is open to the bottom surface 131 of the main body case (main body case (The bottom surface 131 has an opening 423.)

[0041] As shown in Figures 7 and 15, the front side surface 403 is the bottom surface 131 of the main body case (a predetermined surface) It is perpendicular to (an example of). Also, a pair of vertical rear sides 405 and a pair of inclined rear sides 4 07 connects to the left side 409 or right side 411 by sandwiching the hook receiving side 419 from both sides. It is designed to allow this to happen. As mentioned above, since the pair of front sleeve surfaces 503 are perpendicular to the surface 557, The pair of front sleeve surfaces 503, which are the longitudinal reference surfaces of the Teri 501, are brought into contact with the front side surface 403. This allows for accurate and easy placement of the battery 501 in the battery housing 401. It is possible. Note that the front side 403 does not need to be perpendicular to the bottom surface 131 of the main case. However, the inclination angle of the pair of front sleeve surfaces 503 with respect to the surface 557 is adjusted according to the front side surface 403. By doing so, the battery 501 is housed in the battery housing 401 in the same orientation. It can be configured.

[0042] The vertical rear side 405 and the inclined rear side 407 on each side are connected. The vertical rear side 405 of each side is almost perpendicular to the bottom surface 131 of the main case. The inclined rear side 407 is inclined at an angle of about 10 degrees so as it approaches the rear side 413, so as it moves forward. It is. The hook receiving side surface 419 protrudes forward relative to the vertical rear side surface 405 and the inclined rear side surface 407. This is the resulting plane, which is almost parallel to the inclined side surface 407. The left side 409 and the right side 411 are almost perpendicular to the bottom surface 131 of the main case. The rear side 413 is almost parallel to the bottom surface 131 of the main case.

[0043] The front protrusion 415 (corresponding to the "first protrusion" of the present invention) is located on the bottom surface 13 of the main body case. It protrudes backward at the central part of the boundary between 1 and the front side 403 (excluding the parts near both ends). It is provided in such a manner, and as shown in Figure 13, it constitutes a part of the bottom surface 131 of the main case. It has such a surface. Also, the width of the front projection 415 in the front-rear direction, up-down direction and lateral direction The position is such that when the battery 501 is housed in the battery housing 401, the battery 501 The front engagement groove 511 is designed to engage.

[0044] As shown in Figures 13 and 7, a pair of rear protrusions 417 (the "second protrusion" of the present invention) Corresponding to: ) are the boundary edges of the main case bottom surface 131 and the pair of vertical rear sides 405, respectively. It is provided so as to protrude forward from a position adjacent to the hook receiving side surface 419, It has a surface that forms part of the bottom surface 131 of the main case. Also, a pair of rear protrusions 41 The width and position of 7 in the front-to-back, up-to-down, and side-to-side directions are such that the battery 501 is housed in the battery enclosure. When housed in section 401, the surfaces of the pair of rear protrusions 417 facing the rear side surface 413 are Each is positioned to contact a pair of hook shoulder portions 529 of the battery 501.

[0045] Therefore, in the direction along the boundary between the rear side surface 413 and the front side surface 403, the front protruding portion 41 The area where part 5 is located and the area where the pair of rear protrusions 417 are located differ in some respects. The finger recess 421 is located in the rear center of the battery housing 401 on the bottom surface 131 of the main case. It is being done.

[0046] The depth, width in the front-to-back and left-to-right directions, and position of the finger recess 421 are determined by the battery 501 When the battery is placed in the battery housing 401, the front edge of the finger recess 421 is where the battery 50 The back surface of the top of hook 1 535 (the surface facing the same direction as the back surface 555) comes into contact, and further, The finger recess 421 is designed to accommodate a person's finger. A terminal recess 471 is provided near the center in the width direction towards the front of the rear side surface 413. Yes, they are. The terminal recess 471 includes a negative terminal installation section 461, a control signal terminal installation section 465, and The positive terminal mounting sections 463 are arranged in this order from left to right. Multiple negative terminals 441 are provided in the negative terminal installation section 461. Multiple control signal terminals 449 are provided in the control signal terminal installation section 465. Multiple positive terminals 445 are provided in the positive terminal installation section 463.

[0047] As shown in Figures 7 and 21, there are multiple negative terminals 441 and multiple control signal terminals 44 9 and each of the multiple positive terminals 445 (hereinafter referred to as "each terminal 441, 449, 445") The pin has a V-shape. This V-shape extends from the rear side 413 to the main body. The case has tops 443, 451, and 447 that face towards the bottom surface 131 of the case, along the front-to-back direction. It is a raised structure. Also, the mountain shape extends from the tops 443, 451, and 447 to the rear end. It has an inclined portion that approaches the rear side surface 413 as it moves towards the second side end. .

[0048] Each terminal 441, 449, and 445 has its tops 443, 451, and 447 further than its rear side 413. It is designed so as not to protrude from the opening 423 side (the bottom surface 131 side of the main case). As will be described later, when housing the battery 501 in the battery housing 401, the battery 5 When the pair of edges 561 of 01 move in translation while in contact with the rear side surface 413, the battery Avoid contact between the pair of edges 561 of 501 and each terminal 441, 449, and 445. It is being removed. Furthermore, when housing the battery 501 in the battery housing 401, the edge portion 5 Since 62 is spaced apart from the rear side surface 413, this also allows the edge portion 562 to be positioned at each terminal 4 Contact with 41, 449, and 445 is avoided.

[0049] Each negative terminal 441 is positioned in front of each control signal terminal 449 and each positive terminal 445. It is positioned as follows: Therefore, on the rear side 413, each negative terminal 4 is located from the front side 403. The distance to 41 is from the front side 403 to each control signal terminal 449 and each positive terminal 445. It's shorter than the distance at [location].

[0050] A waterproof annular projection 473 is provided in the area adjacent to the terminal recess 471 on the outside. The annular projection 473 is for waterproofing when the battery 501 is housed in the battery housing 401. It is positioned to contact the annular packing portion 589. This allows the waterproof annular protrusion 4 to contact the packing portion 589. The area surrounded by 73 and the waterproof annular packing portion 589 (the surface of the terminal recess 471 and Waterproofing can be ensured in the region sandwiched between the surfaces of the electrode protrusion 587.

[0051] Furthermore, around the waterproof annular projection 473, there are terminal recesses 471 and projection-forming recesses 475. A recess 475 for forming a protrusion is formed so that a waterproof annular protrusion 473 is formed in between. Therefore, the recess 475 for forming the protrusion is formed on the outer peripheral portion of the waterproof annular protrusion 473. This is how it works. The recess 475 for forming the protrusion may be divided into multiple parts with gaps in between. In such cases, the waterproof annular projection 473 will also be divided into multiple parts separated by gaps.

[0052] As shown in Figure 13, when the battery 501 is housed in the battery housing 401 Then, the front projection 415 engages with the front engagement groove 511 (see Figure 9), and a pair of rear projections The surface facing the rear side surface 413 of the strip 417 is the pair of hook shoulder portions 529 of the battery 501 (Figure (See 8) Because it comes into contact with the battery, the battery 501 does not pop out of the battery housing 401. It will be prevented.

[0053] Also, as shown in Figure 14, the battery 501 is housed in the battery housing 401. In this configuration, the height of the surface 557 of the battery 501 matches the height of the bottom surface 131 of the main body case. The height of the battery 501 and the depth of the battery housing 401 are adjusted relative to each other. In such a case, the surface 557 of the battery 501 and the bottom surface 131 of the main case are on the same plane. Yes. Therefore, the surface 557 of the battery 501 housed in the battery housing 401 is an exposed surface. This will form part of the bottom surface 131 of the main case. Therefore, the battery housing 40 A cover is no longer needed to enclose the battery 501 housed in 1.

[0054] (5) Operation when the battery is installed in the battery compartment Next, referring to Figures 15 to 20, the battery 501 is housed in the battery housing 401. I will explain the actions involved.

[0055] When housing the battery 501 in the battery housing 401, as shown in Figures 15 to 20. The printer 1 is placed on a stand or similar surface so that the bottom surface 131 of the main case faces upwards. ru.

[0056] First, as shown in Figure 15, the area near the edge 561 of the battery 501 is the battery housing 40 The front side of the battery 501 is inserted into the battery housing 401 until it contacts the rear side surface 413 of 1. At this time, the rear side of the battery 501 is in contact with the battery housing 401. It is tilted to prevent insertion.

[0057] Next, as shown in Figure 16, the rear portion of the battery 501 is a pair of batteries 501. The edge portion 563 is a pair of vertical rear sides 405 (or a pair of inclined rear sides) of the battery housing portion 401 It is lowered until it contacts surface 523). When it is lowered, the edge of the battery 501 5 Unit 61 moves toward the front side 403 while remaining in contact with the rear side 413.

[0058] Next, as shown in Figures 17, 18, and 19, the pair of edges 56 of the battery 501 3 or a pair of inclined rear sides 523 are a pair of inclined rear sides 407 of the battery housing 401 or The battery 501 falls either in contact with or without contact with a pair of vertical rear sides 405. The rear portion can be lowered. When lowered, the edge portion 561 of the battery 501 is on the rear side. It gradually moves toward the front side surface 403 while remaining in contact with surface 413.

[0059] Therefore, when the rear portion of the battery 501 goes down, the edge portion of the battery 501 5 Translational motion along the rear side surface 413 of 61 and the battery 501 pivoting at its edge 561 Battery 501 moves in such a way that it includes rotational motion of TERI 501.

[0060] During this downward movement, the hook body 537 is positioned against the rear projection 417 of the battery housing 401. To make contact, the hook portion 527 bends toward the main body of the battery 501. Before bending, the hook portion The part indicated by 527R is shown, and the hook portion after bending is indicated by 527. Also, the hook body portion 537 is a rear side projection. After passing through the rib portion 417, the hook shoulder lower inclined surface 533 comes into contact with the rear protruding rib portion 417. The deflection of the hook portion 527 increases rapidly.

[0061] As shown in Figure 20, the entire back surface 555 of the battery 501 is on the back side of the battery housing 401 The movement of the battery 501 ends when it comes into contact with surface 413, as shown in Figure 13. The battery 501 is housed in the battery housing 401.

[0062] At this time, the inclined surface 533 below the hook shoulder has crossed over the rear projection 417, as described above. Thus, the surfaces facing the inner side surface 413 of the pair of rear protrusions 417 are the pair of battery 501 The hook is in contact with the shoulder portion 529.

[0063] Furthermore, the battery 501 is located on the rib 404 provided on the front side surface 403 of the battery housing 401. The front beam portion 507 abuts against the battery housing portion 401, and the battery is in contact with the pair of vertical rear side surfaces 405. A pair of vertical rear sides 521 of 501 abut against a pair of inclined rear sides 4 of the battery housing 401. A pair of inclined rear sides 523 of the battery 501 abut against 07, and the left side of the battery housing 401 The left side surface 551 of the battery 501 is in contact with surface 409, and the right side surface 41 of the battery housing 401 When the right side surface 553 of the battery 501 comes into contact with 1, the battery housing 401 The battery 501 is housed in such a way that it cannot move in the front-to-back or left-to-right directions.

[0064] Next, near the tilted position shown in Figure 18, the negative of battery 501 The electrode surface 591 of electrode 581 and the multiple corresponding surfaces of the battery housing 401 The top 443 of the INAS terminal 441, the electrode surface of the multiple control signal electrodes 585 of the battery 501 The tops of the surface 591 and the multiple control signal terminals 449 of the battery housing 401 corresponding thereto The electrode surface 591 of the positive electrode 583 of part 451 and the opposite of these The tops 447 of the multiple positive terminals 445 of the corresponding battery housing 401 are as shown in Figure 21. They sometimes have a similar arrangement.

[0065] In Figure 21, the position of the top 443 of each negative terminal 441 in the front-to-back direction is y1 and and the front-to-back direction of the tops 447 and 451 of each positive terminal 445 and each control signal terminal 449 ( Let y2 be the position in the FR-RR direction.

[0066] The height z1 at position y1 of the electrode surface 591 of the negative electrode 581 is the height of each negative terminal Since the height z1 of the top 443 of 441 coincides with the height z1 of the surface, the negative electrode 581 is each negative Contact terminal 441.

[0067] On the other hand, the height z2 at position y2 of the electrode surface 591 of the positive electrode 583 is, The lower side (LO side) (upper side in Figure 21) relative to the height z1 of the surface of the top 447 of terminal 445 Since it is located in ), the positive electrode 583 does not come into contact with each positive terminal 445.

[0068] Similarly, the height z2 of the electrode surface 591 of the control signal electrode 585 at position y2 is determined by each control The lower side (LO side) of the surface of the top 451 of the signal terminal 449 relative to the height z1 (Figure 21) Since it is located on the upper side, the control signal electrode 585 does not come into contact with each control signal terminal 449.

[0069] In other words, when the battery 501 has a specific tilted position as shown in Figures 18 and 21 In this configuration, the negative electrode 581 contacts each negative terminal 441, but the positive electrode 583 does not The positive terminals 445 do not make contact, and the control signal electrodes 585 do not make contact with the control signal terminals 449. Do not touch.

[0070] In the process of housing the battery 501 in the battery housing 401, the battery 501 Before assuming the above posture, the battery 501 is tilted even more when viewed from the side (back (Although surface 555 is further inclined with respect to the rear side surface 413), in this case, the negative electrode 5 81 is not in contact with any of the negative terminals 441.

[0071] Furthermore, in the process of housing the battery 501 in the battery housing 401, After 01 assumes the above posture, the tilt of battery 501 when viewed from the side becomes even less. It gets smaller (the inclination of the back surface 555 relative to the back side surface 413 decreases), From the angle of inclination, in addition to the negative electrode 581 contacting each negative terminal 441, The positive electrode 583 contacts each positive terminal 445, and the control signal electrode 585 contacts each control This will make contact with signal terminal 449.

[0072] Therefore, in the overall process of housing the battery 501 in the battery housing 401, First, contact is made between the negative electrode 581 and each negative terminal 441, and then the positive electrode... Contact is made between 583 and each positive terminal 445, and at the same time, the control signal electrode 585 and each control Contact occurs at signal terminal 449.

[0073] After contact is made between the positive electrode 583 and each positive terminal 445, the negative electrode 581 and each A contact sequence that causes contact with the negative terminal 441 can cause damage to the printer's circuitry. According to the combination of the battery 501 and the battery housing 401 of this embodiment, They are being avoided.

[0074] Furthermore, after contact is made between the control signal electrode 585 and each control signal terminal 449, the negative voltage A contact sequence that causes contact between pole 581 and each negative terminal 441 can also cause damage to the printer's circuitry. This can cause damage. The combination of the battery 501 and the battery housing 401 in this embodiment If so, this is avoided.

[0075] The battery 501 is placed in the battery housing 401 with its orientation reversed. If you try to do so, the edge portion 567 located near the boundary between the surface 557 and the pair of vertical rear side surfaces 521 ( (See Figure 8) This interferes with the pair of rear protrusions 417, making it difficult to house the battery 501. It's not possible.

[0076] Also, by reversing the front-to-back direction of the battery 501, the battery 501 is placed in the battery housing 401. When attempting to accommodate it, the edge portion 561 interferes with the pair of rear protrusions 417, and It is not possible to accommodate Terri 501.

[0077] Furthermore, the battery 501 is reversed in both the vertical and horizontal directions to store the battery 501. When attempting to accommodate it in the container 401, the surface 557 and the pair of front sleeve surfaces 503 near the boundary A pair of edge portions 565 (see Figure 9) interfere with a pair of rear protrusions 417, and It is not possible to accommodate Terri 501. In other words, the battery 501 should only be used in the correct orientation in both the vertical and horizontal directions. It can be stored in the battery storage section 401.

[0078] In order to remove the battery 501 housed in the battery compartment 401, the user must Insert your finger into the finger recess 421, bend the hook top 535 toward the main body, then insert your finger into the finger recess 4 Insert your finger between 21 and the top of the hook 535 and lift the top of the hook 535. First, do this. Then, for example, pinch the left side 551 and the right side 553 of the battery 501. Then, lift up the battery 501.

[0079] In the above embodiment, the battery housing section of the printer and the components housed therein I have explained using a battery as an example, but such a battery housing and the contents housed therein The battery may be applied to other electronic devices.
