Such a convex portion forming recess 475 may be divided into a plurality of portions with gaps therebetween. In such a case, the waterproof annular projection 473 is also divided into a plurality of parts with gaps therebetween.

[0052] As shown in FIG. 13, when the battery 501 is housed in the battery housing portion 401, The front projection 415 engages with the front engagement groove 511 (see FIG. 9), and the pair of rear projections The surface of the rib portion 417 facing the rear side surface 413 is connected to a pair of hook shoulders 529 (see FIG. 8), the battery 501 will not jump out of the battery storage section 401. It is prevented.

[0053] 14, when the battery 501 is housed in the battery housing 401, In this case, the height of the surface 557 of the battery 501 is the same as the height of the bottom surface 131 of the main body case. The height of the battery 501 and the depth of the battery storage section 401 are adjusted to each other so that In this case, the surface 557 of the battery 501 and the bottom surface 131 of the main body case are flush with each other. Therefore, the surface 557 of the battery 501 accommodated in the battery accommodating portion 401 is an exposed surface. This forms a part of the bottom surface 131 of the main body case. Therefore, a cover for covering the battery 501 housed in the battery compartment 1 is not required.

[0054] (5) Operation when inserting the battery into the battery compartment Next, referring to FIGS. 15 to 20, the battery 501 is accommodated in the battery accommodating portion 401. This section explains the operation when

[0055] When the battery 501 is housed in the battery housing portion 401, the battery 501 is housed in the battery housing portion 401 as shown in FIGS. Therefore, the printer 1 is placed on a table or the like with the bottom surface 131 of the main body case facing upward. do.

[0056] First, as shown in FIG. 15, the vicinity of the edge portion 561 of the battery 501 is The front side of the battery 501 is inserted into the battery storage section 401 until it abuts against the rear side surface 413 of the battery storage section 401. At this time, the rear side of the battery 501 is inserted into the battery storage section 401. It is angled to prevent insertion.

[0057] Next, as shown in FIG. 16, the rear side of the battery 501 is The peripheral edge 563 of the battery accommodating portion 401 is formed by a pair of vertical rear side surfaces 405 (or a pair of inclined rear side surfaces 405). When lowered, the battery 501 is lowered until it abuts the edge 523. 61 moves toward the front side surface 403 while remaining in contact with the rear side surface 413 .

[0058] Next, as shown in FIGS. 17, 18 and 19, a pair of peripheral edges 56 of the battery 501 are The pair of inclined rear side surfaces 523 are the pair of inclined rear side surfaces 407 of the battery storage section 401 or The battery 501 is dropped onto the pair of vertical rear side surfaces 405 with or without contact. The rear portion is lowered. When lowered, the edge 561 of the battery 501 is While in contact with surface 413, it gradually moves toward front side surface 403.

[0059] Therefore, when the rear side portion of the battery 501 is lowered, the peripheral portion 5 The translational movement along the rear side surface 413 of the battery 61 and the battery movement with the edge portion 561 of the battery 501 as the fulcrum. The battery 501 moves in a manner that includes rotational movement of the battery 501 .

[0060] During this downward movement, the hook body 537 contacts the rear protrusion 417 of the battery storage section 401. Due to the contact, the hook portion 527 is bent toward the main body of the battery 501. The hook body 537 is shown as 527R, and the hook part after bending is shown as 527. After passing through the ridge portion 417, the hook shoulder lower inclined surface 533 abuts against the rear protrusion portion 417. , the deflection of the hook portion 527 increases rapidly.

[0061] As shown in FIG. 20, the entire back surface 555 of the battery 501 is located at the rear side of the battery storage section 401. When the battery 501 comes into contact with the surface 413, the battery 501 stops moving and, as shown in FIG. The battery 501 is housed in the battery housing portion 401 .

[0062] At this time, the hook shoulder lower inclined surface 533 has climbed over the rear protruding portion 417, In this way, the surfaces of the pair of rear protrusions 417 facing the inner side surface 413 of the battery 501 are It abuts against the hook shoulder 529 .

[0063] In addition, the battery 501 is attached to a rib 404 provided on the front side surface 403 of the battery storage section 401. The front beams 507 of the battery holder 401 abut against the pair of vertical rear side surfaces 405 of the battery holder 401. The pair of vertical rear side surfaces 521 of the battery storage section 401 abut against each other, and the pair of inclined rear side surfaces 4 The pair of inclined rear side surfaces 523 of the battery 501 abuts against the left side of the battery storage section 401. The left side surface 551 of the battery 501 abuts against the surface 409, and the right side surface 41 of the battery storage portion 401 abuts against the surface 409. When the right side surface 553 of the battery 501 abuts against the battery holder 401, Thus, the battery 501 is housed so as not to be able to move in the forward / backward and left / right directions.

[0064] Next, the battery 501 is in a negative state in the vicinity of the inclined position shown in FIG. The electrode surfaces 591 of the battery electrodes 581 and the corresponding multiple masks of the battery housing 401 are The top 443 of the inertial terminal 441 and the electrode surface of the plurality of control signal electrodes 585 of the battery 501 The tops of the control signal terminals 449 of the battery accommodating portion 401 and the corresponding surfaces 591 are The electrode surface 591 of the positive electrode 583 of the battery 501 and the The tops 447 of the corresponding positive terminals 445 of the battery holder 401 are as shown in FIG. Sometimes they have a similar arrangement.

[0065] In FIG. 21, the position of the top 443 of each negative terminal 441 in the front-rear direction is defined as y1. The tops 447 and 451 of the plus terminals 445 and the control signal terminals 449 are The position in the FR-RR direction is defined as y2.

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

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

[0068] Similarly, the height z2 of the electrode surface 591 of the control signal electrode 585 at the position y2 is The lower side (LO side) (in FIG. 21) of the surface of the top 451 of the control signal terminal 449 is Since the control signal electrodes 585 are located on the upper side, they do not come into contact with the control signal terminals 449 .

[0069] That is, when the battery 501 has a specific tilted posture as shown in FIGS. In this case, the negative electrode 581 contacts each negative terminal 441, but the positive electrode 583 , the control signal electrodes 585 are not in contact with the positive terminals 445, and the control signal electrodes 585 are not in contact with the control signal terminals 449. Do not touch.

[0070] In the process of accommodating the battery 501 in the battery accommodating section 401, the battery 501 Before taking the above posture, the battery 501 is tilted further when viewed from the side (back). In this case, the negative electrode 5 81 also does not contact the respective negative terminals 441.

[0071] In addition, in the process of accommodating the battery 501 in the battery accommodating section 401, After the battery 501 has taken the above posture, the inclination of the battery 501 becomes even less when viewed from the side. Although the inclination of the rear surface 555 relative to the rear surface 413 becomes smaller, From the angle of inclination, the negative electrode 581 not only contacts each negative terminal 441 but also , the positive electrode 583 contacts each positive terminal 445, and the control signal electrode 585 contacts each control It comes into contact with the signal terminal 449 .

[0072] Therefore, in the entire process of accommodating the battery 501 in the battery accommodating section 401, First, the negative electrode 581 contacts each negative terminal 441, and then the positive electrode 583 and each positive terminal 445 come into contact, and at the same time, the control signal electrode 585 and each control Contact of the control signal terminal 449 occurs.

[0073] After the positive electrode 583 and each positive terminal 445 come into contact, the negative electrode 581 and each The contact sequence that causes the negative terminal 441 to contact may cause damage to the printer circuit. According to the combination of the battery 501 and the battery storage section 401 of this embodiment, Being avoided.

[0074] After the control signal electrode 585 and each control signal terminal 449 come into contact with each other, The contact order in which the pole 581 and each negative terminal 441 come into contact with each other may also cause damage to the printer circuit. This may cause damage to the battery 501. If so, this is avoided.

[0075] The battery 501 is placed in the battery storage section 401 with the top and bottom of the battery 501 turned upside down. When this is done, the peripheral portion 567 ( 8) interferes with the pair of rear protrusions 417, making it impossible to accommodate the battery 501. cannot be done.

[0076] In addition, the battery 501 is placed in the battery storage section 401 with the front and rear directions reversed. When attempting to store the battery, the peripheral portion 561 interferes with the pair of rear protrusions 417, Teri 501 cannot be accommodated.

[0077] Furthermore, the battery 501 is placed in the battery storage container with the top and bottom directions and the front and back directions of the battery 501 reversed. When the container 401 is to be accommodated, the surface 557 and the pair of front sleeve surfaces 503 are in contact with each other near the boundary. A pair of edge portions 565 (see FIG. 9) interfere with a pair of rear protrusions 417, Teri 501 cannot be accommodated. In other words, the battery 501 can only be installed in the correct orientation both vertically and longitudinally. The battery can be housed in the battery housing 401.

[0078] To remove the battery 501 housed in the battery housing 401, the user , insert a finger into the finger recess 421, bend the hook top 535 toward the main body, and then insert the finger into the finger recess 421. Insert your finger between the hook 21 and the hook top 535 to lift the hook top 535. Then, for example, pinch the left side surface 551 and the right side surface 553 of the battery 501. Then, the battery 501 is lifted up.
