This invention relates to an automatic toilet paper feeder. A toilet paper driving motor (19) is actuated by a detection signal from a non-contact sensor (34) for a period set by a timer (33) to deliver a predetermined length of toilet paper, and when this paper is cut by cutters (24, 24'), one operation cycle is completed to prepare for the next cycle. A safety circuit (S) of a cutter motor (28) is provided so that when foreign matters exceeding the cutting power of the cutters (24, 24') are clamped between them, a cutter motor (28) is rotated reversely and the cutters (24, 24') are returned to the original operation start position. Toilet paper driving rollers (10, 11) are made of non-metallic flexible members (10b, 11b) divided into a plurality of segments in order to prevent the toilet paper, which is easily chargeable, from being entangled due to electrostatic suction and a contact portion (31b) having a small area is provided on a guide plate (31) below the cutters (24, 24'). The movable blades (24b, 24b') of the cutters (24, 24') are brought into pressure contact with fixed blades (24a, 24a') by a spring (26) so as to cut sharply the soft and flexible toilet paper (5). A receiving portion (32) is formed in an L-shape so that the toilet paper (5) delivered in the predermined length can be folded into a predetermined width and supplied irrespective of its delivered length. The receiving portion is also adjustable in a vertical direction. An openable cover (1a) is disposed on the front surface of the case (1) so that when any paper or foreign matter is clamped in the toilet paper driving rollers (10, 11) or the cutters (24, 24'), it can be removed easily by opening the cover (1a). When this cover (1a) is opened, the power switch is turned off so that the clamped matter can be removed safely. |
