Abstract: PURPOSE:To exactly detect leak water in a much earier stage by a vary simple constitution in which a leak water sensing section is provided in contact with a water-using apparatus and the floor on which the apparatus is set. CONSTITUTION:When the leakage of water from a water-using apparatus 17 occurs, the water is directed by its own osmotic pressure to the apparatus 17 and a floor 18 on which the apparatus 17 is set. A leak water sensing section 11 set between the apparatus 17 and the floor 18 can respond to the occurrence of water leak immediately, and the leak water is imbibed by the blotting paper 14 of the sensing section 11. Electrodes 12a and 12b embedded in the section 11 in a lattice-like form is normally insulated. When the blotting paper 14 having electrodes 12a and 12b contains sufficient moisture, the electrodes 12a and 12b become conductive through the resistance of water. Therefore, by applying differently polar voltages between the electrodes 12a and 12b through a lead wire 13 from a leak water sensor main unit 15, the leakage of water can be made possible.

Abstract: PURPOSE:To ensure the assured recording and reading with a simple constitution, by shifting a head with the rotary driving power of a disk recording medium and at the same time setting an optical reflecting surface and a nonreflecting surface to a driving power transmission member to set them opposite to the head position. CONSTITUTION:The rotary driving power of a driving motor which turns a direct-coupled disk is transmitted via a gear 39, a gear 40 unified with the gear 39, a gear 41, a gear 42 unified with the gear 41 and having a noninterference part 52, a fan-shaped gear 43, etc. Thus a head arm 45 rocks to move a head 44 to  the radius direction of the disk. When the disk has a turn, the engagement between the gears 42 and 43 is released by the part 52. Then the arm 45 is reset to  its home position by the elastic force of a spring. At the same time, both an  optical reflecting part and a nonreflecting part are formed to a sheet 65 unified  with the gear 41 to be opposite to the position of the head 44. Thus the arrival  of the head 44 to both the home position and to the reading end position is detected sufficiently by a photoelectric transducer 64. In such way, both the recording and reading can be performed assuredly with a simple constitution.
