Abstract

In compact card-like equipment having an IC chip and a power source cell, an equipment case has a multilayered structure of a pair of upper and lower sheets and a pair of upper and lower panels laminated on a frame, respectively. A flexible substrate and a paper-like cell as a primary cell are provided in the equipment case. The paper-like cell has a pair of positive and negative electrode sheets and a power generating unit interposed therebetween. A sealing member seals the peripheries of the electrode sheets of the paper-like cell. The paper-like cell is received in a receptacle space formed in the frame. The flexible substrate is received in another receptacle space formed in the frame. The electrode sheets of the paper-like cell are electrically connected to terminals of the flexible substrate by means of a film-like connecting member. This compact card-like electronic equipment such as a calculator is thin and compact in size.

Claims

1. A compact electronic device, comprising:

upper case means;

lower case means having an area substantially corresponding with that of said upper case means;

frame means interposed between said upper and lower case means and having a cut-out section and a shape substantially corresponding to peripheral edges of said upper and lower case means, said frame means and said upper and lower case means together defining first and second receptacle spaces, said cut-out section also defining an opening which communicates with said second receptacle space and which is open to an outside of said lower case means;

an electronic component arranged to be located in said first receptacle space;

a battery cell having upper and lower electrodes, said upper and lower electrodes being substantially flat;

a cell receiving member having a thin frame portion which is shaped substantially corresponding to the peripheral edge of said battery cell, said cell receiving member with said battery cell fitted therein being adapted to be detachably mounted in said second receptable space through and cut-out section;

conductive lead means for electrically connecting said upper and lower electrodes of said battery cell to said electronic component; and

fixing means for fixing said upper and lower case means together with said frame means with said frame means being interposed between said upper and lower case means.

2. The compact electronic device of claim 1, wherein said frame portion has a recess in said second receptacle space, and said cell receiving member has a projection which is engaged with said recess.

3. A compact electronic device, comprising:

upper case means;

lower case means having an area substantially corresponding with that of said upper case means;

frame means interposed between said upper and lower case means and having a cut-out section and a shape substantially corresponding to peripheral edges of said upper and lower case means, said frame means and said upper and lower case means together defining first and second receptacle spaces, said cut-out section also defining an opening which communicates with said second receptacle space and which is open to an outside of said lower case means;

an electronic component arranged to be located in said first receptacle space;

a battery cell having upper and lower electrodes, said upper and said lower electrodes being substantially flat;

a cell receiving member for receiving said battery cell and being adapted to be detachably mounted in said second receptacle space with said battery cell fitted therein through said cut-out section;

conductive lead means for electrically connecting said upper and lower electrodes of said battery cell to said electronic component; and

adhesive means for adhering the peripheries of said upper and lower case means together with said frame means with said frame means being interposed between said upper and lower case means.

4. The compact electronic device of claim 3, wherein said electronic component is adhered to one of said upper and lower case means.

5. The compact electronic device of claim 3, wherein said frame means and said cell receiving member each include an engaging section, respectively, for engaging each other when said cell receiving member is mounted in said second receptacle space.

6. The compact electronic device of claim 5, wherein said cell receiving member has substantially the same thickness as said frame means.

7. The compact electronic device of claim 6, wherein said cell receiving member includes a frame portion, and a bottom plate mounted below said frame portion.

8. The compact electronic device of claim 7, wherein said cell receiving member has a conductor on said bottom plate for contacting one of said upper and lower electrodes of said battery cell.

9. A compact electronic device, comprising:

an electronic component;

a battery cell having upper and lower electrodes, said upper and lower electrodes being substantially flat;

a cell receiving member having at least a frame portion which is shaped substantially corresponding to the peripheral edge of said battery cell for receiving said battery cell, said cell receiving member having an engaging section;

a first case means;

a second case means having an area substantially corresponding with that of said first case means, said first and second case means each defining a receptacle space which is formed by surrounding peripheral edges thereof for receiving and storing said electronic component and said cell receiving member, said second case means having an opening which communicates with said receptacle space and which is open to an outside of said second case means through one of said peripheral edges, and engaging means for engaging said engaging section of said cell receiving member when said cell receiving member is mounted in said receptacle space;

conductive lead means for electrically connecting said upper and lower electrodes of said battery cell to said electronic component; and

fixing means for fixing the peripheries of said first and second case means relative to one another.

10. The compact electronic device of claim 9, wherein said fixing means is an adhesive.

11. The compact electronic device of claim 10, wherein said electronic component is adhered to one of said first and second case means.

12. The compact electronic device of claim 9, wherein said cell receiving member includes a bottom plate mounted below said frame portion.

13. The compact electronic device of claim 12, wherein said cell receiving member includes a conductor on said bottom plate for contacting one of said upper and lower electrodes of said battery cell.

14. The compact electronic device of claim 9, wherein said fixing means fixes said first and second case means with said first and second case means superposed on one another.
