摘要： PURPOSE:To prevent a recording paper sheet from removing from a separation pawl if a forward motion force is given to the recording paper sheet by impact or vibration at non-feeding time so as to apply a paper sheet feeder to portable printers or the like. CONSTITUTION:At other than sheet feeding time, a picking roller 13 is moved up to get apart from a recording paper sheet 2 in a paper sheet cassette 3. In up-motion of the picking roller 13, an arm 14 is oscillated to oscillate a lever 12 by an energization force of a twisted coil spring 17 corresponding to displacement of a suspension member 14a of the arm 14, and a front plate part 12b of the lever 12 is applied to an upper end surface of a front wall of the paper sheet cassette 3 at an up-motion position of the picking roller 13 by this oscillation action. In non-feeding time, therefore, the front plate part 12b of the lever 12 advances to the front of the recording paper sheet 2 in the paper sheet cassette 3, thereby if a moving force to the front is given to the recording paper sheet 2 by impact or vibration, the recording paper sheet 2 is not removed from a separation pawl 25.

摘要： PURPOSE:To set a separation pawl large for preventing removal of engagement of a recording sheet with the separation pawl by vibration or impact at other times than sheet feeding, without generating inconveniences such as paper jam is sheet feeding so as to apply a sheet feeder to portable printers or the like. CONSTITUTION:When a picking roller 16 is moved up at other than sheet feeding time, a separating pawl 12 is displaced inward in the width direction of a recording sheet 2 by an energization force of a plate spring 15 by up-motion of a cam shaft 25, a diameter-enlarged part 25a of the cam shaft 25 is applied to a protruding member 12d of the separation pawl 12 to give a pressure to the separation pawl 12 to the outer side in the width direction of the recording sheet 2 so as to displace the separation pawl 12 to the outer side in the width direction of the recording sheet 2 against the energization force of the plate spring 15. The separation pawl 12 is thus positioned at the outer side of the width of the recording sheet 2 in sheet feeding time than the position in non- feeding time, and if the separation pawl 12 is set large for preventing removal of engagement of the recording sheet 2 with the separation pawl 12 by vibration or impact in non-feeding, engagement condition of the recording sheet can be proper in sheet feeding.

摘要： PURPOSE: To operate a human body detector at all times without resting on an external power source by making up it with a generating set producing electric power with a water flow, a condensing set storing the generated electricity and a body detecting sensor detecting the presence of a user. CONSTITUTION: In order to store water in a water storage tank 2 again after flushing a toilet bowl, water is fed to the tank from a feed water pipe 2b. Then the water fed to an upper cover 2a of the tank 2 flows down toward an inner part of the tank 2 from a hole part 2c. Next, a water turbine 6a is rotated by dint of the fallen water and this rotation is transmitted to a first pulley 6b via a second pulley and a belt 6m, thereby rotating the turning shaft of a generator 6f. Thus this generator 6f operates for generation. In succession, electric power generated is stored in a condensing set 8 connected to this generator 6f. This condensing set 8 serves as a power source for a body detecting sensor 4, supplying electricity to this sensor 4. With this constitution, since a generating set is operated by way of utilizing the power of flushing water, electric charges are thus savable.

摘要： PURPOSE:To enable an ink residual amount to be certainly detected by a method wherein a pair of electrodes are conducted to each other through a one side foam material, ink existing in a pipe, and another side foam material. CONSTITUTION:Electrodes 10a, 10b are conducted to each other through a foam material 8a, ink in a pipe 9, and a foam material 8b. When the ink is consumed and the ink in the foam material 8a is gone, circulation of the ink via a pipe comes not to be performed, and a current between the electrodes 10a, 10b is intercepted by the pipe 9 having an insulating property. Said no conduction between the electrodes 10a, 10b is detected with a detection circuit, and the condition is regarded as 'no ink'. Since the ink remains yet in the foam material 8b, printing can be a little performed yet after display of 'no ink'. Further since how degree printing can be performed to is determined by a volume of a second chamber 6b, when a residual amount is required to be strictly detected, the second chamber 6b should preferably be made as small in volume as possible.
