As shown in FIGS. 7 and 15, the front side surface 403 is perpendicular to the bottom surface 131 of the main body case (an example of a predetermined surface). Further, the pair of vertical rear side surfaces 405 and the pair of inclined rear side surfaces 407 are provided so as to sandwich the hook receiving side surface 419 from both sides and connect to the left side surface 409 or the right side surface 411.
As described above, since the pair of front sleeve surface 503 is perpendicular to the surface 557, the pair of front sleeve surfaces 503, which is the reference surface in the longitudinal direction of the battery 501, is brought into contact with the front side surface 403. The battery 501 can be accurately and easily accommodated in the battery accommodating portion 401.
The front side surface 403 does not have to be perpendicular to the bottom surface 131 of the main body case. Even in that case, by adjusting the inclination angle of the pair of front sleeve surface 503 with respect to the surface 557 according to the front side surface 403, the battery accommodating portion 401 can be configured to accommodate the battery 501 in the same posture. ..

The vertical rear side surface 405 and the inclined rear side surface 407 on each side are connected to each other. The vertical rear side surface 405 on each side is substantially perpendicular to the bottom surface 131 of the main body case. The inclined rear side surface 407 on each side is inclined about 10 degrees toward the front as it approaches the back side surface 413.
The hook receiving side surface 419 is a plane protruding forward with respect to the vertical rear side surface 405 and the inclined rear side surface 407, and is substantially parallel to the inclined rear side surface 407.
The left side surface 409 and the right side surface 411 are substantially perpendicular to the bottom surface 131 of the main body case. The back side surface 413 is substantially parallel to the bottom surface 131 of the main body case.

The front ridge portion 415 (corresponding to the "first ridge portion" of the present invention) protrudes rearward at the central portion (the portion excluding the vicinity of both ends) of the boundary between the bottom surface 131 of the main body case and the front side surface 403. As shown in FIG. 13, it has a surface that constitutes a part of the bottom surface 131 of the main body case. Further, the width and position of the front ridge portion 415 in the front-rear direction, the vertical direction, and the lateral direction are determined so that the front engagement groove 511 of the battery 501 engages when the battery 501 is housed in the battery housing portion 401.

The faces facing each other are determined to be in contact with the pair of hook shoulders 529 of the battery 501, respectively.

Therefore, in the direction along the boundary between the back side surface 413 and the front side surface 403, the range where the front side ridge portion 415 is located and the range where the pair of rear side ridge portions 417 are located are partially different.
The finger recess 421 is provided in the rear center portion of the battery accommodating portion 401 of the bottom surface 131 of the main body case.

The depth, width and position of the finger recess 421 in the anteroposterior and lateral directions are such that when the battery 501 is housed in the battery housing section 401, the front edge of the finger recess 421 is located on the back surface of the hook top 535 of the battery 501. (A surface facing the same direction as the back surface 555) is in contact with the finger, and at that time, it is determined that a human finger can be inserted into the finger recess 421.
A terminal recess 471 is provided near the center of the back side surface 413 in the width direction toward the front.
In the terminal recess 471, the negative terminal installation portion 461, the control signal terminal installation portion 465, and the positive terminal installation portion 463 are arranged in this order from the left.
A plurality of negative terminals 441 are provided in the negative terminal installation portion 461.
The control signal terminal installation unit 465 is provided with a plurality of control signal terminals 449.
A plurality of positive terminals 445 are provided in the positive terminal installation portion 463.

As shown in FIGS. 7 and 21, each of the plurality of negative terminals 441, the plurality of control signal terminals 449, and the plurality of positive terminals 445 (hereinafter referred to as “each terminal 441, 449, 445”) is bent in a chevron shape. It has the shape of a pin. The chevron shape is raised along the front-rear direction so as to have tops 443, 451 and 447 facing from the back side surface 413 toward the bottom surface 131 of the main body case. Further, the chevron shape has an inclined portion that approaches the back side surface 413 toward the rear end portion (the end portion on the second side surface side) from the top portions 443, 451 and 447.

The terminals 441, 449, and 445 are provided so that the top portions 443, 451 and 447 do not protrude toward the opening 423 side (main body case bottom surface 131 side) from the back side surface 413. Therefore, as will be described later, when the battery 501 is accommodated in the battery accommodating portion 401, when the pair of edge portions 561 of the battery 501 translate while contacting the back side surface 413, the pair of edge portions of the battery 501 are moved. It is avoided that the portion 561 and the terminals 441, 449, and 445 come into contact with each other. When the battery 501 is housed in the battery accommodating portion 401, the edge portion 562 is separated from the back side surface 413, so that the edge portion 562 also comes into contact with the terminals 441, 449, and 445. It is avoided to end up.

Each negative terminal 441 is arranged in front of each control signal terminal 449 and each positive terminal 445. Therefore, on the back side surface 413, the distance from the front side surface 403 to each minus terminal 441 is shorter than the distance from the front side surface 403 to each control signal terminal 449 and each plus terminal 445.

A waterproof annular convex portion 473 is provided in the outer adjacent region of the terminal recess 471. The waterproof annular convex portion 473 is provided so as to come into contact with the waterproof annular packing portion 589 when the battery 501 is housed in the battery accommodating portion 401. As a result, waterproofness can be ensured in the area surrounded by the waterproof annular convex portion 473 and the waterproof annular packing portion 589 (the area sandwiched between the surface of the terminal recess 471 and the surface of the electrode convex portion 587). can.

Around the waterproof annular convex portion 473, a convex portion forming concave portion 475 is formed so that a waterproof annular convex portion 473 is formed between the terminal concave portion 471 and the convex portion forming concave portion 475. .. Therefore, the convex portion forming concave portion 475 is formed on the outer peripheral portion of the waterproof annular convex portion 473. Such a concave portion 475 for forming a convex portion may be divided into a plurality of portions with a gap in between. In such a case, the waterproof annular convex portion 473 is also divided into a plurality of portions with a gap in between.

As shown in FIG. 13, when the battery 501 is housed in the battery housing section 401, the front ridge portion 415 engages the front engagement groove 511 (see FIG. 9), and the pair of rear side bumps also. Since the surface of the strip 417 facing the inner side surface 413 abuts on the pair of hook shoulder portions 529 (see FIG. 8) of the battery 501, the battery 501 is prevented from popping out from the battery accommodating portion 401.

Further, as shown in FIG. 14, when the battery 501 is housed in the battery accommodating portion 401, the height of the battery 501 is such that the height of the surface 557 of the battery 501 matches the height of the bottom surface 131 of the main body case. And the depth of the battery housing 401 is adjusted between each other. At such times, the surface 557 of the battery 501 and the bottom surface 131 of the main body case are on the same plane. Therefore, the surface 557 of the battery 501 housed in the battery accommodating portion 401 becomes an exposed surface and constitutes a part of the bottom surface 131 of the main body case. Therefore, a cover for covering the battery 501 housed in the battery housing section 401 becomes unnecessary.

(5) Operation when accommodating a battery in the battery accommodating portion Next, an operation when accommodating the battery 501 in the battery accommodating portion 401 will be described with reference to FIGS. 15 to 20.

When the battery 501 is housed in the battery housing section 401, the printer 1 is placed on a table or the like so that the bottom surface 131 of the main body case faces upward as shown in FIGS. 15 to 20.

First, as shown in FIG. 15, the front surface side of the battery 501 is inserted into the battery accommodating portion 401 until the vicinity of the peripheral portion 561 of the battery 501 abuts on the inner side surface 413 of the battery accommodating portion 401. At this time, the battery 501 is inclined so that the rear surface side of the battery 501 is not inserted into the battery accommodating portion 401.

Next, as shown in FIG. 16, in the rear surface side portion of the battery 501, a pair of edge portions 563 of the battery 501 are formed on a pair of vertical rear side surfaces 405 (or a pair of inclined rear surface surfaces 523) of the battery accommodating portion 401. It can be lowered until it touches. When lowered, the edge 561 of the battery 501 moves toward the front side surface 403 while still in contact with the back side surface 413.

Next, as shown in FIGS. 17, 18 and 19, a pair of edge portions 563 or a pair of tilted rear side surfaces 523 of the battery 501 is a pair of tilted rear side surfaces 407 or a pair of vertical rear side surfaces of the battery accommodating portion 401. The rear portion of the battery 501 is lowered so that it falls in contact or non-contact with respect to 405. When lowered, the edge 561 of the battery 501 gradually moves toward the front side surface 403 while still in contact with the back side surface 413.

Therefore, when the rear surface side portion of the battery 501 is lowered, the translational motion along the inner side surface 413 of the peripheral portion 561 of the battery 501 and the rotational motion of the battery 501 with the peripheral portion 561 of the battery 501 as a fulcrum are included. Battery 501 is in motion.

During this descent period, the hook body 537 abuts on the rear ridge 417 of the battery housing 401, so that the hook 527 bends toward the body of the battery 501. The hook portion before bending is indicated by 527R, and the hook portion after bending is indicated by 527. Further, after the hook body portion 537 passes through the rear side ridge portion 417, the hook shoulder lower inclined surface 533 abuts on the rear side ridge portion 417, so that the bending of the hook portion 527 rapidly increases.

As shown in FIG. 20, the movement of the battery 501 is terminated when the entire back surface 555 of the battery 501 abuts on the inner side surface 413 of the battery accommodating portion 401, and as shown in FIG. 13, the battery 501 is attached to the battery accommodating portion 401. It will be in a housed state.

At this time, the hook under-shoulder inclined surface 533 rides over the rear ridge portion 417, and as described above, the surface facing the back side surface 413 of the pair of rear ridge portions 417 is a pair of hooks of the battery 501. It is in contact with the shoulder portion 529.

Further, the front beam portion 507 of the battery 501 abuts on the rib 404 provided on the front side surface 403 of the battery accommodating portion 401, and the pair of vertical rear side surfaces 521 of the battery 501 are attached to the pair of vertical rear side surfaces 405 of the battery accommodating portion 401. The pair of inclined rear side surfaces 407 of the battery 501 are in contact with each other, the pair of inclined rear side surfaces 523 of the battery 501 are in contact with each other, and the left side surface 551 of the battery 501 is in contact with the left side surface 409 of the battery accommodation unit 401. When the right side surface 553 of the battery 501 abuts on the right side surface 411 of the 401, the battery 501 is accommodated in the battery accommodating portion 401 so as not to move in the front-rear direction and the left-right direction.

Next, the battery 501 has, in the vicinity of the inclined posture shown in FIG. 18, the electrode surface 591 of the negative electrode 581 of the battery 501, the top 443 of the plurality of negative terminals 441 of the battery accommodating portion 401 corresponding thereto, and the plurality of batteries 501. 591 of the electrode surface of the control signal electrode 585 and the top 451 of the plurality of control signal terminals 449 of the battery accommodating portion 401 corresponding thereto, and the electrode surface 591 of the positive electrode 583 of the battery 501 and the corresponding battery accommodating portion 401. The tops 447 of the plurality of positive terminals 445 may have an arrangement relationship as shown in FIG.

In FIG. 21, the position in the front-rear direction of the top 443 of each minus terminal 441 is y1, and the position of the tops 447 and 451 of each plus terminal 445 and each control signal terminal 449 in the front-back direction (FR-RR direction) is y2. ..

Since the height z1 at the position y1 of the electrode surface 591 of the negative electrode 581 coincides with the height z1 of the surface of the top 443 of each negative terminal 441, the negative electrode 581 contacts each negative terminal 441.

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

Similarly, the height z2 at the position y2 of the electrode surface 591 of the control signal electrode 585 is lower (LO side) with respect to the surface height z1 of the top 451 of each control signal terminal 449 (upper side in FIG. 21). Therefore, the control signal electrode 585 does not come into contact with each control signal terminal 449.

That is, when the battery 501 has a specific tilted posture as shown in FIGS. 18 and 21, the negative electrode 581 contacts each negative terminal 441, but the positive electrode 583 does not contact each positive terminal 445. The control signal electrode 585 also does not come into contact with each control signal terminal 449.

In the process of accommodating the battery 501 in the battery accommodating portion 401, before the battery 501 takes the above posture, the battery 501 is further inclined when viewed from the side surface (the back surface 555 is further inclined with respect to the back side surface 413). However, at this time, the negative electrode 581 is also not in contact with each negative terminal 441.

Further, in the process of accommodating the battery 501 in the battery accommodating portion 401, after the battery 501 takes the above posture, the inclination of the battery 501 is further reduced when viewed from the side surface (back side surface 413 of the back surface 555). From a certain tilt angle, 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. The 585 comes into contact with each control signal terminal 449.

Therefore, in the entire process of accommodating the battery 501 in the battery accommodating portion 401, first, the negative electrode 581 and each negative terminal 441 come into contact with each other, and then the positive electrode 583 and each positive terminal 445 come into contact with each other. At the same time, contact between the control signal electrode 585 and each control signal terminal 449 occurs.

A contact sequence in which the positive electrode 583 and each positive terminal 445 come into contact with each other and then the negative electrode 581 and each negative terminal 441 come into contact causes destruction of the printer circuit. According to the combination of the battery 501 and the battery accommodating portion 401 of the present embodiment, this is avoided.

Further, a contact order in which the negative electrode 581 and each negative terminal 441 come into contact after the control signal electrode 585 and each control signal terminal 449 come into contact with each other also causes the printer circuit to be destroyed. According to the combination of the battery 501 and the battery accommodating portion 401 of the present embodiment, this is avoided.

When the battery 501 is to be accommodated in the battery accommodating portion 401 by reversing the vertical direction of the battery 501, a pair of edge portions 567 (see FIG. 8) located near the boundary between the surface 557 and the pair of vertical rear side surfaces 521 are paired. It interferes with the rear ridge 417 and cannot accommodate the battery 501.

Further, when the battery 501 is to be accommodated in the battery accommodating portion 401 by reversing the front-rear direction of the battery 501, the edge portion 561 interferes with the pair of rear ridge portions 417, and the battery 501 is accommodated. Can't.

Further, when the battery 501 is to be accommodated in the battery accommodating portion 401 by reversing the vertical direction and the front-rear direction of the battery 501, the surface 557, the pair of front sleeve surface portions 503, and the pair of edge portions 565 located near the boundary thereof. (See FIG. 9) interferes with the pair of rear ridges 417 and cannot accommodate the battery 501.
That is, the battery 501 can be accommodated in the battery accommodating portion 401 only in the correct orientation in both the vertical and front-back directions.

In order to remove the battery 501 housed in the battery accommodating portion 401, the user inserts a finger into the finger recess 421, bends the hook top 535 toward the main body, and then bends the finger recess 421 and the hook top. Insert your finger between the 535s and lift the hook top 535 first. Then, for example, the left side surface 551 and the right side surface 553 of the battery 501 are pinched to lift the battery 501.

In the above embodiment, the battery accommodating portion provided in the printer and the battery accommodated therein have been described as an example, but such a battery accommodating portion and the battery accommodated therein are applied to other electronic devices. You may.
