Each of the cylindrical portions 15A, 15B, 15C has a length substantially equal to the length of the battery 4, and an inner shape is a size that allows the battery 4 to be inserted substantially inwardly or with a slight gap, and is open at both ends. The one end opening forms a positive electrode side opening 17 and the other end opening forms a negative electrode side opening 18. Further, the cylindrical portions 15A, 15B, 15C are not symmetrical with respect to the longitudinal center line, and are oriented so as to correspond to the plus contacts 6A, 6B, 6C and the minus contacts 7A, 7B, 7C. Are alternately arranged in opposite directions. A locking portion 20 that prevents the battery 4 from coming off by locking the positive electrode side end surface 40 of the battery body 4A of the battery 4 is integrally formed in the positive electrode side opening 17 of each of the cylinder portions 15A, 15B, and 15C. Is provided. On the other hand, the negative electrode side opening 18 is not provided with a locking portion in order to function as an insertion port / outlet of the battery 4 and has the same size as the cross-sectional shape of the cylindrical portions 15A, 15B, 15C. An opening is formed.

Further, the front plate 21 of each of the cylindrical portions 15A, 15B, 15C is provided with a pressing portion 23 that presses the battery 4 against the inner bottom surface 22 of the battery housing hole 16, and the positive electrode 8 and the negative electrode 9 of the battery 4 are provided. A “+” mark M ₁ and a “−” mark M ₂ are displayed. The pressing portion 23 is a long and narrow rectangular tongue in which both sides in the longitudinal direction and one side edge on the short side are separated from the surface plate 21 by forming slits 24 that are substantially U-shaped in the longitudinal direction of the surface plate 21. A protrusion 26 having a V-shaped cross section is integrally provided on the back surface of the tip. At the center of the short side slit portion 24a of the slit 24, a rectangular concave portion 28 is continuously provided, whereby the overall shape of the slit 24 is made to be approximately the same shape (elongated convex shape) as the battery 4, and the mark Together with M ₁ and M ₂ , a storage direction display portion indicating the storage direction of the battery 4 in the battery storage hole 16 is formed.

The mark M ₁ is displayed near the positive electrode side opening 17 on the surface of the surface plate 21, and the mark M ₂ is displayed near the negative electrode side opening 18.

  Further, rectangular recesses 29 and 30 are formed at both ends of the surface plate 21 to allow the belly portion of the fingertip to escape when the battery 4 is stored and taken out. The concave portion 29 allows the belly portion of the fingertip to escape when the positive electrode 8 of the battery 4 is pushed in with a finger during removal. The recess 30 allows the belly portion of the fingertip to escape when the battery 4 is pushed into the battery storage hole 16 during storage.

  In the housing structure of the electronic device having such a structure, when the battery 4 is mounted in the battery housing recess 3 of the housing 1, each battery 4 is placed in each battery housing hole 16 of the battery case 2. 4 is confirmed, and the positive electrode 8 is inserted from the negative electrode side opening 18 with the positive electrode 8 as the insertion side. When the battery 4 is pushed in a certain amount, the protruding portion 26 of the pressing portion 23 hits the outer peripheral surface of the battery 4 and elastically deforms outward, and the battery 4 is pressed against the inner bottom surface 22 of the battery housing hole 16 by its elastic force. Further, when the battery 4 is pushed in, the positive electrode side end surface 40 of the battery 4 comes into contact with the inner surface of the locking portion 20, and the storage of the battery 4 in the battery storage hole 16 is finished. In this stored state, the positive electrode 8 of the battery 4 protrudes from the positive electrode side opening 17, and the negative electrode 9 forms substantially the same plane as the opening surface of the negative electrode side opening 18.

  Next, the battery case 2 is loaded into the battery housing recess 3 of the housing 1. When loading, the battery storage portion 12 is placed in the battery storage recess 3 so that the positive electrode 8 and the negative electrode 9 of the battery 4 are aligned with the positive contacts 6A, 6B, 6C and the negative contacts 7A, 7B, 7C, respectively. The lid 11 is pushed into close contact with the surface of the battery case mounting portion 5. Each battery 4 is inserted between the positive contacts 6A, 6B, 6C and the connecting ends 6a, 6b, 6c and 7a, 7b, 7c of the negative contacts 7A, 7B, 7C by pushing in the battery storage portion 12, respectively. It is pushed and elastically pinched. That is, the connecting ends 6a, 6b, 6c, 7a, 7b, 7c of the plus contacts 6A, 6B, 6C and the minus contacts 7A, 7B, 7C are elastic in the direction away from the battery 4 when the battery 4 is loaded. The battery is deformed and the positive electrode 8 and the negative electrode 9 of the battery 4 are pressed and clamped by the elastic force to obtain a good electrical connection. Then, the two set screws 44 are inserted into the screw attachment holes 13 and screwed into the screw holes 10, thereby completing the attachment of the battery case 2 to the housing 1.

  When the battery 4 is exhausted and replaced with a new one, after removing the set screw 44 and removing the battery case 2 from the housing 1, the positive electrodes 8 of the batteries 4 housed in the respective battery housing holes 16 are sequentially placed. A predetermined amount is pushed with a finger, and the negative side end of the battery 4 is protruded from the negative electrode side opening 18 by a predetermined amount. Then, the protruding end is grasped with a finger and pulled out from the battery housing hole 16, and a new battery is pushed in instead as described above, and then the battery case 2 is loaded again into the battery housing recess 3 of the housing 1. .

  In such a housing structure of an electronic device, it is only necessary to push the battery 4 into and out of the battery housing hole 16 of the battery case 2, so there is no need to hook the fingernail onto the battery 4 and vigorously. The battery 4 can be easily loaded, removed and replaced without fear of jumping out.

In addition, since the battery case 2 is provided with the slit 24 and the marks M ₁ and M ₂ as the storage direction display section for displaying the storage direction of the battery 4 on the surface of the battery storage section 12, the direction of the battery 4 is mistakenly reversed. Thus, it is possible to prevent a storage accident.

  Further, since the battery case 2 is lightly pressed against the inner bottom surface 22 of the battery housing hole 16 by lightly pressing the outer periphery of the battery 4 by the pressing portion 23, the battery 4 moves unnecessarily or from the negative electrode side opening 18. There is no such thing as dropping out.

3 is a perspective view of a main part of a battery case showing another embodiment of the present invention, FIG. 4 is a cross-sectional view of the main part of the housing structure, and FIG. 5 is a cross-sectional view of the main part showing a state when the battery is taken out. FIG.
In the present embodiment, the battery 4 is made of an elastically deformable conductive material as a locking portion provided in each positive electrode side opening 17 of the battery housing portion 12 of the battery case 2 to lock the insertion side end of the battery 4. The elastic piece 50 is used to press the positive electrode 8 toward the inside of the housing hole 16, in other words, toward the negative electrode 9. The elastic piece 50 includes a plate-like pressing piece 50A made of a rigid body, a thin C-shaped elastic deformation portion 50B integrally connected to the base end of the pressing piece 50A, and the elastic deformation portion 50B. The fixing piece 50C is integrally connected to the opposite end to the pressing piece 50A side end, and the fixing portion 50C is set on the surface of the surface plate 21 on the plus electrode side opening 17 side. The positive electrode side opening 17 is normally closed by the pressing piece 50A. Further, a convex portion 53 that presses the distal end surface of the positive electrode 8 of the battery 4 is integrally projected at the distal end portion of the inner surface of the pressing piece 50A, and a contact blocking member 54 made of an insulating material is fixed to the proximal end side. Has been. The contact blocking member 54 is for preventing the negative electrode 9 and the convex portion 53 of the pressing piece 50A from coming into contact with each other when the battery 4 is erroneously inserted into the battery housing hole 16 from the negative electrode 9 side. Is formed thicker than the protruding dimension of the convex portion 53. Since other structures are substantially the same as those of the above-described embodiment, the same components and parts are denoted by the same reference numerals, and description thereof is omitted.

  In such a housing structure of an electronic device, the battery 4 is stored in the battery storage hole 16 of the battery case 2, whereby the positive electrode 8 comes into contact with the convex portion 53 of the elastic piece 50 and stops. Can be confirmed to be normally stored in the battery storage hole 16. In this state, the positive electrode side end surface 40 of the battery 4 does not contact the contact blocking member 54.

  By attaching the battery case 2 to the battery housing recess 3 of the housing 1, the pressing piece 50A of the elastic piece 50 comes into contact with the connecting end 6a of the plus contact 6A, thereby the plus contact 6A and the plus electrode. 8 is electrically connected.

  When the battery case 2 is taken out from the battery housing hole 16 and the battery 4 is replaced with a new battery, the negative electrode 9 of the battery 4 is pressed and moved with a finger, or the positive of the new battery 4A as shown in FIG. The electrode 8A is pressed against the negative electrode 9 of the old battery 4 stored in the battery storage hole 16 and moved, and the positive electrode 8 is pressed against the convex portion 53 of the pressing piece 50A. When the plus electrode 8 presses the convex portion 53, the elastic piece 50 opens the plus electrode side opening 17 of the battery housing hole 16 by the elastic deformation portion 50B elastically deforming outward. Then, in this state, the positive electrode side end of the old battery 4 is grasped with a finger and pulled out from the battery housing hole 16, or the new battery 4A is pushed in as it is, and the old battery 4 is pushed out.

  Even in such a structure, it will be apparent that the electrode 4 can be easily stored, taken out and replaced in the same manner as in the above-described embodiment.
