Definitions

  • a pointer type timer comprises an hour pointer 1, a minute pointer 2 and a second pointer 4 which are respectively driven by an hour gear 11, a minute gear 28 and a second gear 41 through an hour shaft 18, a minute shaft 19 and a second shaft 42.
  • the hour shaft 18, minute shaft 19 and second shaft 42 are preferably co-axially arranged.
  • the second gear 41 is driven by a stepping motor 36 and the minute gear 28 and the hour gear 11 are mechanically connected to the second gear 41 with gear trains of specific gear ratios. This is well known to those skilled in the art and no detail will be necessary herein.
  • a manual button 61 is depressed and rotated to rotate the minute shaft 19 via a gear train constituted partly by the minute gear 191.
  • a micro-switch 62 is triggered to have the central processing unit 24 ready for time calibration and actuate the photo element 30 to monitor the counting disk 29.
  • the counting disk 29 should be reset first, namely the enlarged strip 291 in alignment with the photoelectric element 30.
  • the pointers 1, 2 and 4 and the counting disk 29 are manually rotated clockwise, the count recorded in the central processing unit 24 increases and when the pointers, together with the counting disk 29, is manually rotated counterclockwise, the count in the central processing unit 24 decreases.
  • the central processing unit 24 will then adjust the digital time signal thereof according to the change of the count.
  • a housing (not shown) to have the above-described members or elements disposed therein and a dial face to indicate the time when the pointers are in corresponding positions.
  • the emission of light from the photoelectric element 30 may be under the control of the central processing unit 24 and is conducted only at a short period, for example twenty seconds, before the counting disk 29 completes a turn.
  • a second embodiment of the present invention is shown.
  • the second embodiment is essentially the same as the first embodiment described previously with only the photo-detector and the light emitting device contained in the photoelectric element 30 spaced apart in this embodiment and disposed on the opposite sides of the counting disk 29 on which a plurality of angularly equally-spaced through slits are formed, instead of the attaching thereon the reflective strips, to allow light beams to pass therethrough.
