Time indicating apparatus

Claim 2

A time-indicating apparatus comprising at least one timeindicating body, said timE-indicating body comprising chamberlike illumination cells having front surfaces, said cells being arranged for displaying the time by displaying the hour and minute of the day, said hour and minute being displayed by successively controlled electric signals supplied to the respective illumination bodies of said illumination cells, the front surfaces of the illumination cells being provided with crystal-like cut patterns, the electric signals supplied to the illumination bodies of illumination cells illuminating the hour indication for the duration of an entire hour and successively changing to the next hour indication, the electric signal supply to the illumination bodies of the illumination cells illuminating the minute indication cumulatively with illuminating successive minute indications until a change in the hour indication occurs.

Claim 3

A time-indicating apparatus as set forth in claim 1 wherein the front surfaces of said illumination cells with said crystal-like cut patterns are interchangeable.

Claim 4

A time-indicating apparatus as set forth in claim 1 wherein said chamber-like illumination cells are provided with different colors for said front surfaces to facilitate viewability of said apparatus to determine the time.

Claim 5

A time-indicating apparatus as set forth in claim 1, comprising a fixed disc, a plate composed of a plurality of insulator boards and a plurality of good conductor boards, said plurality of insulator boards and said plurality of conductor boards being multiples of ten and being placed on the circumference of said fixed disc, a rotary disc located opposite said fixed disc, said rotary disc having first and second contact pieces, said contact pieces being good conductors, said contact pieces being separated by a distance equal to the sum of the widths of pairs of insulator boards, a plurality of rotary shafts corresponding to the hour minute and second of the day, said rotary disc being connected to any of said plurality of rotary shafts, and a switch located between said fixed and rotary discs.

Claim 6

A time-indicating apparatus as set forth in claim 1 comprising a rotatable gear for hour-indicating having a number of teeth equal to a multiple of 12, a gear for minute indicting engageable with said gear for hour indicating, said gear for minute indicating having a number of teeth equal to the multiple of twelve of the number of teeth on said hour-indicating gear.

Claim 7

A time-indicating apparatus as set forth in claim 1, wherein a multi-contact point switch having a ratchet wheel with 12 teeth is threaded to one end of a drum, said teeth being rotatable by means of a feed pawl secured to a driving lever driven by an attraction piece intermitently attracted by a manget, a stepped plate having 12 steps being secured to the surface of said drum, 12 switching arms being disposed in contact with the surface of the drum. each of said 12 switching arms corresponding to a respective step of said stepped plate, a common contact piece being disposed in a position to make contact with said switching arms when said switching arms are pushed by said stepped plate, a pawl-shaped cam being threaded at the other end of said drum, said ratchet wheel being arranged so that it makes one twelfth of a revolution for each revolution of said cam, and a rotary contact piece for contacting said 12 contact points, said rotary contact piece being secured to the shaft of said ratchet wheel.

Claim 8

A time-indicating apparatus as set forth in claim 1, comprising a time-indicating board wherein transparent electrodes are placed at both sides of an electroluminous substance layer, a first electroluminscence panel, a second electroluminescence panel, said first and second panels covering the periphery of said transparent electrodes and being respectively disposed at the hour and minute indicating areas, time being indicated by the illumination of electroluminescence panels in the hour and minute indicating areas by illuminating the electrolumiNous substance with a pulse voltage being applied to each electroluminescence panel.

Claim 9

A time-indicating apparatus as set forth in claim 1, comprising an oscillator circuit having a plurality of frequency generating means, an adder connected to receive at least a plurality of input signals of different frequencies, a band-pass filter connected to said adder to allow only signals having a predetermined frequency to pass therethrough, and an amplitude regulating circuit connected to the output of said band-pass filter.

Claim 10

A time-indicating apparatus as set forth in claim 1 comprising a time-indicating board having a plurality of hour-indicating sections, each of the hour-indicating sections, each of the hour-indicating sections having the same color as each of the corresponding minute-indicating sections, each of the hour-indicating sections having different colors from the other of the hour-indicating sections, said time-indicating board being provided with crystal-like cut patterns, said cut patterns being located on the coloar transparent surface thereof.

Claim 11

A time-indicating apparatus as set forth in claim 1, wherein said time-indicating body comprises two sections, a first of said two sections displaying the hour of the day and the second of said two sections displaying the minute of a day, said sections being linearly displayed.

Claim 12

A time-indicating apparatus as set forth in claim 1 wherein said time-indicating body comprises two sections, a first of said two sections displaying the hour of the day and the second of the two sections displaying the minute of the day. said two sections being co-axial with said hour display being located within said minute display.
