By opening the opening / closing lid 4, a new spare paper roll R can be stored in the spare roll space V2, and the tubular core R1 can be easily removed from the tubular core receiver 12. .

Here, the operation of the cam portion 62 of the paper guide 6 and the first and second cam surfaces S1, S2 of the mandrel 5 will be described.

First, as shown in FIG. 20, when the preliminary roll supporting portion 60 of the paper guide 6 is at the upper position B1, as shown in FIGS. 23 (a) and 23 (b),
The first cam 62c of the paper guide 6 is the cylindrical portion 5 of the mandrel 5.
1c, and the second cam 62d of the paper guide 6 is near the first cam surface S1 below the mandrel 5 on the driven portion 51 side. In this case, the mandrel 5 has a support protrusion 5
Since a moment acts such that the supporting portion 50 rotates downward by its own weight around the center 2, this mandrel 5 is
The rotation due to its own weight is regulated by the first cam 62c, and the support portion 50 is positioned in a horizontal state protruding into the holder main body 2.

Next, as shown in FIG. 21, when the paper guide 6 rotates to some extent about the center line M, as shown in FIGS. 23 (c) and (d), the first cam 62 is rotated.
c rises and escapes to the spherical surface side of the cylindrical portion 51c of the second cam surface S2, and the second cam 62d rises while sliding on the first cam surface S1 to raise the first cam surface S1 upward. Push up. For this reason, the support part 50 of the mandrel 5 rotates downward by a predetermined angle, and becomes in an oblique state. In this case, the above-described state is promoted by the moment of the mandrel 5 due to its own weight.

Next, as shown in FIG. 22, when the preliminary roll supporting portion 60 of the paper guide 6 is lowered to the lower position B2, as shown in FIGS. In the first cam surface S2, the second cam 62d moves upward while sliding on the first cam surface S1, while the second cam 62d slides over the first cam surface S1. The cam surface S1 is further pushed upward. Therefore, the support portion 50 of the mandrel 5 is in a substantially vertical state, and is in a state of being immersed in the opening 22 d of the holder main body 2. In this case, also in this case, the moment due to its own weight promotes the above state.

Next, when the preliminary roll supporting portion 60 of the paper guide 6 rotates from the lower position B2 to the upper position B1, the first cam 62c descends and the second cam 62d escapes downward. The support portion 50 of the mandrel 5 is moved from a vertical state to a horizontal state, and projects into the holder main body 2.

As described above, in the toilet paper holder 1, the first and second cams 62 of the paper guide 6 are provided.
By sliding the mandrel c and 62d on the first and second cam surfaces S1 and S2 of the mandrel 5, the mandrel 5 is rotated in a smooth motion. The roll R can be moved in and out of the cylindrical core R1. Therefore, the slider 10 can be moved up and down with a relatively small force via the paper guide 6, so that the operation of the lever portion 101 of the slider 10 can be performed with a small force. On the other hand, since the slider 10 can move up and down with a relatively small force, the spring force of the slider spring 11 for raising the slider 10 can be reduced accordingly, and the elastic force of the slider spring 11 can be reduced as in this embodiment. When operating the lever portion 101 while opposing it, the operation of the lever portion 101 can be performed with a small force as much as the spring force of the slider spring 11 is further reduced.

When the preliminary roll supporting portion 60 of the paper guide 6 is at the upper position B1, the first cam 62c of the paper guide 6 for restricting the rotation of the mandrel 5 and the second cam 62 of the mandrel 5 are controlled.
Since the cam surface S2 is in contact with the cam surface S2 in a substantially horizontal state (FIG. 23)
(B)), even if the weight of the paper roll R is applied to the support portion 50 side of the mandrel 5, this load can be applied to the paper guide 6.
It does not act in the direction in which is turned. Therefore, when the preliminary roll support portion 60 is located at the upper position B1, the slider spring 11 only needs to have a spring force enough to support the weight of the slider 10 and the cylindrical core receiver 12, and the like. When the portion 60 reaches the lower position B2, the spring force of the slider spring 11 can be reduced,
Accordingly, the force applied to the lever portion 101 can be reduced.

In the toilet paper holder 1, the paper guide 6 is formed with the preliminary roll support portion 60 which reciprocates between the upper position B1 and the lower position B2. Tube core R1
When moving outside, the spare paper roll R moved to the use position C2 side can be temporarily temporarily held by the spare roll support portion 60 easily. In this case, the auxiliary roll support unit 60 at the upper position B1 also serves as a storage for the auxiliary paper roll R, and when the auxiliary roll support unit 60 moves from the upper position B1 to the lower position B2, the auxiliary roll support unit 60 Since the paper roll R is dropped downward, the storage of the preliminary paper roll R and the movement (fall) to the lower position C2 are performed by the preliminary roll support portion 60.
It can be done easily and with good timing.

Further, the toilet paper holder 1
Then, the first cam surface S1 and the second cam surface S2 are formed on the lower surface side and the upper surface side of the driven portion 51 of the mandrel 5, respectively, and the first cam 62c and the second cam 62d of the paper guide 6 form the first and second cam surfaces S1 and S2. Since the driven portion 51 is sandwiched, the mandrel 5 can be surely rotated even when a cam mechanism is used. Therefore, even if dirt or the like gets stuck around the support projection 52 of the mandrel 5, the support portion 50 can be reliably moved into and out of the cylindrical core R1 of the paper roll R, and the mandrel 5 is unstablely rotated to the side without the cam. There is no need to move it.

Further, in the toilet paper holder 1, when the spare paper roll R is dropped from the reserve position C1 to the use position C2, the cut portion of the paper cutter 8 is prevented so as not to hinder the fall of the paper roll R. Since the separation mechanism is provided to separate the cutting portion 80 from the mandrel 5 (paper roll R), the spring force of the cutter spring 9 that presses the cut portion 80 toward the paper roll R can be sufficiently increased. For this reason, the paper cutter 8
Even if the paper is cut with one hand without holding down, the paper cutter 8 can be prevented from rattling and the paper can be cut with one hand.

Further, the toilet paper holder 1
Then, by moving the cylinder core receiver 12 forward with the rotation of the paper guide 6, the cylinder core receiver 12
Since the falling tube core R1 is caught, the tube core receiver 12 is not rotated before the paper guide 6 that does not need to catch the tube core R1, that is, before the lever cap 13 is operated. Can be positioned on the mounting surface side of the toilet paper holder 1 without interfering with the use of the paper roll R. In this case, the cylindrical core receiver 12 may move (rotate) relatively to the paper guide 6.

In the toilet paper holder 1, the tube core receiver 12 is attached to the lower end side of the paper guide 6 so as not to move relative to the paper guide 6, and when the tube core R1 is to be caught, the core receiver is used. Since the portion 121 is positioned in an oblique state in which it protrudes forward, even if the drop position of the tube core R1 is deviated or the tube core R1 falls obliquely so as to be slightly forward, the tube core receiver 12 can be used. Thereby, the cylinder core R1 can be reliably caught. Therefore, it is not necessary to increase the size of the core receiving portion 121 side of the cylindrical core receiver 12, and the size of the cylindrical core receiver 12 can be reduced. Further, the cylindrical core receiver 12 does not rattle when the paper guide 6 rotates, and does not hit the mounting surface side of the toilet paper holder 1. Needless to say, the tube core receiver 12 is easily attached to and detached from the paper guide 6, and thus may be removed if unnecessary.

In the toilet paper holder 1, the spare roll supporting portion 60 of the paper guide 6 at the upper position B1 has a function as a storage tray for the spare paper roll R. The auxiliary paper roll R may be dropped from the storage table to the use position C2 side in accordance with the timing at which the auxiliary roll support unit 60 moves to the lower position B2. in this case,
Many paper rolls can be stored on this storage table.

Next, the toilet paper holder 1
Will be described. This lock mechanism allows the slider 10 to move up and down via the lever portion 101 when the opening / closing lid 4 is open, but when the opening / closing lid 4 is closed, the cut portion 80 of the paper cutter 8 The slider 10 cannot be moved up and down via the lever 101 unless the paper roll R has sufficiently moved to the tube core R1 side.

The lock mechanism includes first and second lock bars 14 and 15 and first and second lock springs 16 and 17.
, A projection 41 of the opening / closing lid 4, a lock projection 103c of the slider 10, and the like.

As shown in FIG. 16, the first lock bar 14 has an upper arm 141
And the lower arm portion 142 are formed so as to extend in a straight line, and the support portion 140 is formed on the pedestal portion 26 of the holder body 2.
a is rotatably attached to a through a fixing screw 18B. At the upper end of the upper arm portion 141, the second
A projection 141a to be inserted into the lock hole 22f is formed, and a second lock bar 15
Projection 142 inserted into guide hole 153a (described later) of
a is formed. Further, a spring receiver 142b is formed on the lower arm portion 142, and the first lock bar 14 is formed by the first lock spring 16 attached to the spring receiver 142b and the spring receiver 27b of the holder body 2 as shown in FIG.
The middle portion is biased in a counterclockwise direction around the fixing screw 18B.

As shown in FIG. 17, the second lock bar 15 has a support portion 151 formed at the lower end of a vertically extending main body 150 and a lock which engages with and disengages from the lock projection 103c of the slider 10 on the right side. A projection 152 is formed. A projection 153 having a guide hole 153a and a spring receiver 154 are formed on the rear surface of the main body 150, and a first lock hole 22e of the holder main body 2 is formed on the front of the main body 150. Extending rod part 155
Are formed. The second lock bar 15 is configured such that the support portion 151 is fixed to the pedestal portion 26 b of the holder body 2 by a fixing screw 18.
It is rotatably mounted via C. And
The second lock spring 17 is urged by the second lock spring 17 attached to the spring receiver 154 and the spring receiver 27c of the holder body 2 in the counterclockwise direction around the fixing screw 18C in FIG. ing.

Next, the operation of the lock mechanism will be described. First, as shown in FIG. 24, a case where the opening / closing lid 4 is open and the projection 41 of the opening / closing lid 4 is separated from the projection 141a of the first lock bar 14 will be described.
In this case, the first lock bar 14 is
The second lock bar 15 is pressed and urged counterclockwise around the fixing screw 18B by the action of the fixing screw 18B.
A force is applied clockwise around 8C. On the other hand, the second lock bar 15 is pressed and urged in the counterclockwise direction by the second lock spring 17, but since the spring force of the first lock spring 16 is stronger than the spring force of the second lock spring 17, the second lock bar 15 is pressed. The lock projection 15 of the second lock bar 15 is rotated slightly clockwise around the fixing screw 18C.
2 is a lock projection 1 formed on the back side of the slider 10
It is positioned at a position shifted to the right from immediately below 03c.

For this reason, the slider 10 can be lowered to the operating position A2 by pushing the lever portion 101 downward, and the setting work of the paper roll R and the like on the toilet paper holder 1 becomes possible.

Next, the case where the open / close lid 4 is closed as shown in FIG. 25 will be described. In this case, the protrusion 14
Since the projection 1a is pressed by the projection 41, the first lock bar 14 is slightly rotated clockwise while resisting the elastic force of the first lock spring 16. For this reason, the second lock bar 15 is also fixed by the fixing screw 1 by the action of the second lock spring 17.
It rotates counterclockwise around 8C until the projection 142a hits the edge of the guide hole 153a. As a result, the lock projection 152 of the second lock bar 15 is positioned immediately below the lock projection 103c of the slider 10, and
Even if the lever part 101 is pushed downward, the lock projection 103c
Hits the lock projection 152, the slider 10 cannot be lowered, and the setting operation of the paper roll R and the like on the toilet paper holder 1 cannot be performed.

On the other hand, as shown in FIG.
Is closed, but the case where the paper roll R in use is substantially only the cylindrical core R1 will be described. In this case, the support portion 81 of the paper cutter 8 pushes the rod portion 155 of the second lock bar 15 rightward by the action of the cutter spring 9, so that the second lock bar 15
7, while slightly rotating clockwise while resisting the elastic force of the lock 7, the lock protrusion 152 is displaced from the position of the lock protrusion 103c. Therefore, the slider 10 can be lowered to the operation position A2 by the lever portion 101, and the setting operation of the paper roll R and the like on the toilet paper holder 1 can be performed.

As shown in FIG. 19, when the slider 10 is moved to the lower operation position A2, the lock projection 152 of the slider 10 is positioned immediately below the lock projection 103c of the second lock bar 15. However, since the upper end of the lock projection 152 and the lower end of the lock projection 103c are separated by an inclined surface, the lever cap 1
By releasing the hand from 3, the slider 10 can return to the non-operation position A1.

As described above, since the toilet paper holder 1 prevents the slider 10 from descending when it is not necessary, the used paper roll R with the paper still remaining may be discharged. In addition, the paper roll R can be set at any time as long as the opening / closing lid 4 is opened, thereby facilitating use. If the opening / closing lid 4 can be opened / closed by using a key, it is not necessary to open the opening / closing lid 4 unnecessarily and move the slider 10 up and down.
