Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
211 words
A reminder comprising: a tape recoder capable of recording therein a tape recording of which something to be done at some time is reserved; a clock electrically connected to said tape recoder, capable of time setting and adapted to be electrically connected to a power supply; an alarming unit having an alarming circuit and a buzzing speaker and electrically connected to said clock so that said speaker can buzz when said time at which it is set in said clock arrives; and two interlinking switches one of which is electrically connected to said alarming circuit which is energized and de-energized by said power supply respectively when said one switch is switched on and off respectively, and the other of which is kept switched off and on respectively when said one switch is switched on and off respectively, and electrically connected to said tape recorder which can be energized and de-energized respectively, when said the other switch is kept switched on and off respectively whereby said speaker will buzz when said time set in said clock arrives and when said one switch is switched off and said the other switch is switched on and thus said tape recorder will play to reproduce said tape recording to remind one to do said something.
Claim 2
Dependent Claim
211 words
A reminder comprising: a tape recoder capable of recording therein a tape recording of which something to be done at some time is reserved; a clock electrically connected to said tape recoder, capable of time setting and adapted to be electrically connected to a power supply; an alarming unit having an alarming circuit and a buzzing speaker and electrically connected to said clock so that said speaker can buzz when said time at which it is set in said clock arrives; and two interlinking switches one of which is electrically connected to said alarming circuit which is energized and de-energized by said power supply respectively when said one switch is switched on and off respectively, and the other of which is kept switched off and on respectively when said one switch is switched on and off respectively, and electrically connected to said tape recorder which can be energized and de-energized respectively, when said the other switch is kept switched on and off respectively whereby said speaker will buzz when said time set in said clock arrives and when said one switch is switched off and said the other switch is switched on and thus said tape recorder will play to reproduce said tape recording to remind one to do said something.
Claim 3
Dependent Claim
17 words
A reminder according to claim 1 wherein said buzzing speaker is capable of volume and tone adjusting.
Claim 4
Dependent Claim
62 words
A reminder according to claim 2, further comprising a transfer switch to which said clock, said tape recorder and said power supply are electrically connected and when switched in a first position said clock and said tape recorder are electrically connected to each other and when switched in a second position said clock and said tape recorder are in an electrical interruption.
Claim 5
Dependent Claim
49 words
A reminder according to claim 3 wherein the tape of said tape recorder is a loop tape and said tape recorder further electrically connects a first delay circuit which enables said tape recorder to erase said tape recording at a later time after said tape recording has been played.
Claim 6
Dependent Claim
37 words
A reminder according to claim 4 wherein said clock is an electronic clock having light emitting diodes (LEDs) set for time indication and an integrated circuit (IC) for clock use being electrically connected to said tape recorder.
Claim 7
Dependent Claim
42 words
A reminder according to claim 5 wherein said tape recorder further electrically connects to a second delay circuit which enables said tape recorder to repetitiously reproduce said tape recording at a later time after said the other switch has been switched on.
Claim 8
Dependent Claim
17 words
A reminder according to claim 6 wherein said power supply is an automatic AC/DC switching power supply.
