Claims
- 1. An electronic instrument, comprising:
- solar battery means for converting light energy into electric energy;
- display means for displaying information;
- an upper member having front and back sides, said upper member comprising a flexible sheet, said solar battery means and said display means being mounted in the region of said back side, said upper member further having a first portion permitting light to be incident on said solar battery means and a second portion permitting information displayed on said display means to be perceived from the exterior of said instrument, said upper member further comprising at least one key symbol;
- a circuit substrate having an area smaller than that of said upper member and comprising a circuit pattern including at least one fixed contact, corresponding to said at least one key symbol, used for key input;
- an integrated circuit element connected to said at least one fixed contact;
- movable contact means positioned between said upper member and said circuit substrate, a key input to said integrated circuit element being obtained by contact of said movable contact means with said at least one fixed contact;
- spacing means normally for maintaining said movable contact means spaced from said at least one fixed contact of said circuit substrate when said at least one key symbol of said upper member is not depressed and for permitting said movable contact means to contact said at least one fixed contact of said circuit substrate to produce a key input when said at least one key symbol is depressed;
- a lower member provided at a position to sandwich said circuit substrate between at least a portion of said lower member and at least a portion of said upper member, said lower member having a recessed area formed within the periphery thereof, said recessed area receiving said circuit substrate, said solar battery means, said display means and said spacing means within the height of said lower means; and
- means for adhesively securing said upper member to the periphery of said lower member.
- 2. An electronic instrument according to claim 1, wherein said movable contact means are mounted with said back side of said flexible sheet.
- 3. An electronic instrument according to claim 1 wherein said circuit substrate has contacts for establishing electrical connection to said solar battery means and said display means.
- 4. An electronic instrument according to claim 1, wherein said lower member comprises frame means having a recessed area for positioning said solar battery means and said display means, and reinforcing plate means fixed on one side of said frame means by the adhesion.
- 5. An electronic instrument comprising:
- solar battery means for converting light energy into electric energy;
- display means for displaying information;
- a first member having a front side and a back side, said first member comprising a flexible sheet, said solar battery means and said display means being mounted in the region of said back side, said first member further having a first portion permitting light to be incident on said solar battery means and a second portion permitting information displayed on said display means to be perceived from the exterior of said instrument, said first member further comprising at least one key symbol;
- a circuit substrate having an area smaller than that of said first member and comprising a circuit pattern including at least one fixed contact, corresponding to said at least one key symbol, used for key input;
- an integrated circuit element connected to said at least one fixed contact;
- movable contact means positioned between said first member and said circuit substrate, a key input to said integrated circuit element being obtained by contact of said movable contact means with said at least one fixed contact;
- spacing means normally for maintaining said movable contact means spaced from at least one said fixed contact of said circuit substrate when said at least one key symbol of said upper member is not depressed and permitting said movable contact means to contact said at least one fixed contact of said circuit substrate to produce a key input when said at least one key symbol is depressed;
- frame means formed so as to accommodate said solar battery means, said display means, said circuit substrate, and said spacing means within the height of said frame means, said solar battery means and said display means being located within an area surronded by said frame means;
- a second member provided at a position to sandwich said circuit substrate and said frame means between at least a portion of said second member and at least a portion of said first member;
- means for securing said first member to the periphery of said frame means; and
- means for securing said second member to the periphery of said frame means.
- 6. An electronic instrument according to claim 5, wherein said movable contact means are mounted with said back side of said first member.
- 7. An electronic instrument according to claim 5, wherein said circuit substrate has contacts for establishing electrical connection to said solar battery means and said display means.
