On the other hand, the occasion that stops when motor 13, make paper feed roller 7 rotations if twitch cylinder paper 2 with hand this moment, then because of engaging tooth 31b deviates from from recess 32b under the elastic reaction of its elasticity wrist 31a, from the rotation of paper feed roller 7 not to ratchet 32 side transmission.That is, this rotation is not passed to motor 13, so the influence of the stop moment that has when not stopped by motor 13, thereby, can make paper feed roller 7 rotations simply.For this reason, even when switching on, can manually easily not extract cylinder paper 2 out yet.
In the present embodiment, as shown in Figure 4, one-way clutch 17 is set at from motor 13 nearest motor 13 sides in the gear train to paper feed roller 7.Therefore, when manual operation, because of the speedup to one-way clutch 17 is subjected to big moment of torsion from paper feed roller 7, and when motor 13 drives on the one-way clutch 17 suffered moment of torsion reduce, thereby can adopt the little one-way clutch of endurance 17.
In addition, as shown in Figure 3, the gear train of reducing gear 14 is pressed transversely arranged setting.Thus, can prevent that cap 6 is too high.
And, be provided with the paper knife 18 that is used for the cylinder paper 2 that severing sends at the other end 5 of cap 6.This paper knife 18 is made by rubber.Thereby, can utilize paper knife 18 easily with 2 severings of cylinder paper.
In addition, take in the control part 19 that drive division 8 is controlled in the cap 6.Control part 19 as shown in Figure 5, has: quantity is no less than 2 the 1st, the 2nd switch 21,22; To the 1st timing circuit 23 and the 2nd timing circuit of setting the actuation time of carrying out action because of arbitrary switch open in the 1st, the 2nd switch 21,22 24 as timer; 1st, the AND gate circuit 25 of both actions when opening simultaneously of the 2nd switch 21,22; According to the control circuit 26 of output signal to controlling as the drive motor 13 of drive division 8 from the 1st, the 2nd timing circuit 23,24 or AND gate circuit 25.When opening separately, the 1st switch 21 sends the cylinder paper 2 of specific length, cylinder paper 2 when when the 2nd switch 22 is opened separately, sending length and being different from the 1st switch 21 and opening, in the present embodiment, send short cylinder paper 2, when the 1st, the 2nd switch 21,22 is opened, send above-mentioned length length in addition.In the present embodiment, at the 1st switch 21 and the 2nd switch 22 while open period, cylinder paper 2 is sent continuously.In addition, also possesses the voltage constant circuit 27 that 12 voltage supplied of power supply are controlled on the control part 19.
And then, as shown in Figure 3, be provided with on cap 6 that the 1st static is removed parts 28 and the 2nd static is removed parts 29.The 1st static is removed parts 28, is used to prevent that the static by the operator causes from producing harmful effect to control circuit, or is used to prevent static to the GND of circuit discharge, is made of the wire spring of the sidepiece of being located at the 1st switch 21 and the 2nd switch 22.The 2nd static is removed parts 29, is used to prevent that the static by cylinder paper 2 takes place from producing harmful effect to control circuit, or is used to prevent static to the GND of circuit discharge, constitutes towards the wire spring that cylinder paper 2 is provided with by being positioned at cap 6 bottoms.These static are removed parts 28,29, and the GND of the wiring board by directly being arranged at control part 19 or power supply 12 goes up and ground connection.These static are removed parts 28,29 for the static because of operator or 2 generations of cylinder paper, play the effect of lightning rod, can prevent the misoperation of control circuit 26.
Above each switch 21,22, as shown in Figure 9, be provided with diaphragm 136.Diaphragm 136 is resinous film.The user presses from diaphragm 136 tops and makes it distortion (the figure, double dot dash line), can press each switch 21,22.The 1st static is removed parts 28 and is arranged to a little more than each switch 21,22.Thus, when pressing diaphragm 136, can under the situation of the operation sense of not damaging switch, contact the 1st static and remove parts 28.Static flows to the 1st little static of resistance value from the user and removes parts 28, the 1 static and remove parts 28 and play the effect of lightning rod for the static from the operator, can prevent to cause control part 19 misoperations because of static.
The 2nd static is removed parts 29, as shown in figure 10, possesses the contact sites of giving prominence to towards cylinder paper 2 133 and reaches the connecting portion 134 that is connected with the GND of control part 19.Contact site 133 is outstanding to cylinder paper 2, is in the state partly accepting and partly rejecting with cylinder paper 2.Contact site 133 is enclosed the flank 135 on the inner casing that is formed at cap 6.Thus, can prevent that contact site 133 is hooked in cylinder paper 2 and deforms.Static flows to the 2nd static from cylinder paper 2 and removes parts 29, the 2 static and remove parts 29 and play the effect of lightning rod for the static from cylinder paper 2, can prevent to cause control part 19 misoperations because of static.
Below, 1 example of the action of above-mentioned rolled paper feeding device 1 is described.
For example, the user opens the 1st switch 21.Thus, as shown in Figure 5, the action of the 1st timing circuit 23, only drive motor 13 (with reference to Fig. 7, long-time pattern) at the appointed time.In addition, when the user opened the 2nd switch 22,24 actions of the 2nd timing circuit had been shorter than the stipulated time internal driving electric machine 13 of the 1st timing circuit 23 (with reference to Fig. 7, the short time pattern).In this long-time pattern and the short time pattern, open because of switch 21,22 both one unlatchings make the 1st timing circuit the 23, the 2nd timing circuit 24, thereby even cut- off switch 21,22, motor 13 also can drive at the appointed time.
In addition,, then enter continuous mode if the user opens two switches 21,22 simultaneously, switch be pressed during in motor 13 is driven.At this moment, the user pressed two switches at 21,22 o'clock, the moment that both switches 21,22 are pressed be difficult to accomplish real synchronously.That is, at first, a certain side among both is pressed earlier, another switch is pressed after the extremely short time difference.For this reason, control circuit at first begins action with the pattern corresponding with the switch of pressing earlier.Subsequently,, two switches 21,22 send the signal of the actuation time of the action that removing carrying out to the 1st timing circuit the 23, the 2nd timing circuit 24, the timer function of stopping using from AND gate circuit 25 because of all being unlocked.And in the present embodiment, then previous pattern is reseted and be transformed into continuous mode.Thus, can prevent that preceding mode from continuing to wait the generation of misoperation.In the continuous mode, the 1st timing circuit the 23, the 2nd timing circuit 24 is failure to actuate, as long as arbitrary switch disconnection promptly stopping motor 13 drives in the switch 21,22.
In addition, in the present embodiment, set the 1st switch, the 2nd switch and both for long-time pattern, short time pattern and continuous mode respectively, but be not limited thereto, for example also the 2nd switch can be set at continuous mode.In addition, the type for pattern also can adopt long-time pattern, short time pattern and continuous mode pattern in addition.
The rotation of motor 13 is passed to paper feed roller 7 by one-way clutch 17 and reducing gear 14.Be subjected to the pressure of cap 6 deadweights on the paper feed roller 7, rely on this pressure can cylinder paper 2 not taken place to rotate slidably, carry.
When cylinder paper 2 rotated, friction took place and produces static in 2 on the housing of containing box casing 3 and cap 6 and cylinder paper.This electrostatic current is removed the contact site 133 of parts 29 to the 2nd static.Thereby, can prevent to cause control part 19 misoperations by static.
In long-time pattern or the short time pattern action of the 1st timing circuit the 23, the 2nd timing circuit 24 at the end, or when switch 21,22 disconnected in the continuous mode, motor 13 stopped operating, the supply of cylinder paper 2 stops.The hand-held cylinder paper of sending 2 of user with it in paper knife 18 places severing.At this moment, because the weight abundance of cap 6, also can be even pin cap 6 with 2 severings of cylinder paper without hand.
On the other hand, when cutting off, just in case when breaking down as power supply 12, or the cylinder paper 2 of specific length still want to extract out after sending a little etc. situation, sometimes need be with manual extraction cylinder paper 2 when motor 13 is in halted state.When the motor 13 of this situation stops, twitching cylinder paper 2 downwards with hand, paper feed roller 7 rotates, reducing gear 14 actions.And one-way clutch 17 idle running, motor 13 break away from from gear train, thereby, not influenced with light and handy power by the stop moment of motor 13 with 2 extractions of cylinder paper.
Present embodiment is sent cylinder paper 2 continuously by opening two switches 21,22, can at random carry out trickle adjustment to sending length.Thereby, can improve the operation conveniency.
In addition, because of carrying out 3 kinds of actions by two switches 21,22, the increase of number of switches is controlled, thereby the cost increase can be reduced to minimum.And just the quantity because of the switch that is provided with is few, and correspondingly switch 21,22 can adopt bigger size, thereby improves the operation conveniency.
