Abstract

PURPOSE:To facilitate taking-out of a core and stabilize payoff operation of roll paper by furnishing a moving force control means to give or release a resistance in accordance with the direction in which the rail is slided. CONSTITUTION:Core 22 of roll paper 21 is fitted on a pin 16 of a holder body 12. This holder body 12 is sunk into the apparatus casing 13 by the weight of the roll paper 21 and stopped when the bottom surface of the body 12 runs against the oversurface of bottom plate 14a of a base frame 14. Meantime, the sinking speed of the holder body 12 is controlled to a proper value by resistance of a one-way rotary damper 19 to be set still in a specified position. When the roll paper 21 is used out, the holder body 12 is pulled up from an upper opening 13a. The holder body 12 is pulled up lightly without encountering the resistance of said one-way rotary damper 19.

Description

[Detailed description of the invention] [Technical field of invention] The present invention relates to a roll paper holder.

[Technical background of the invention]

For example, in receipt issuing machines used at expressway toll gates, the installation space is narrow, so roll paper is loaded through the upper opening of the device housing.

FIG. 2 shows a roll paper holder 1 employed in such equipment. This roll paper holder 1 is
Two side plates 3゜3 are erected on the base frame 2, U-shaped notches 4, 4 are formed in the upper end surfaces of these side plates 3, 3, and a pin 5 is engaged between the notches 4, 4. The pin 5 is inserted into the core 7 of the roll paper 6, and both ends of the pin are placed in the notches 4.4 to load the roll paper 6.

[Problems with background technology]

By the way, in the above-mentioned receipt issuing machine, the area of the upper opening of the device housing in which the roll paper 6 is stored is small, and the roll paper holder 1 is installed in the lower part of the interior, so the loading work of the roll paper 6 and the roll core 7 are difficult. Also, the work to take out the pin 5 was extremely complicated. That is, when loading the roll paper 6,
You must be careful not to drop the pin 5 from the roll core 7 when loading it into the notch 4゜4.If you fail to remove the roll cores 7 and 5 after use, remove your hand from the upper opening. It must be inserted into the equipment housing.

In addition, in the roll paper holder 1 of the above-mentioned receipt issuing machine, there is a risk that the pin 5 may come off from the notches 4, 4 while the roll paper 6 is being used, and in such a case, the roll paper 6 may not be able to be fed out. turn into.

[Purpose of the invention]

In view of the above-mentioned problems, an object of the present invention is to provide a roll paper holder that makes it easy to load roll paper and take out the core after use, and also ensures stable feeding of the roll paper. -There it is.

[Summary of the invention]

Therefore, in the present invention, a holder body having a pin into which a roll core is inserted is fixedly installed on a rail inside the equipment housing (the holder body can be slid freely), and the holder body can be slid in the direction of the base of the rail. A moving force control means is provided to apply resistance when sliding the holder body, and to release the resistance when sliding the holder body toward the free end of the rail, thereby achieving the above objective. The holder is pulled up from inside the equipment casing to the upper opening, one pin supports the roll paper, and the holder body is lowered to set the roll paper at a predetermined position inside the equipment casing. This prevents the holder main body from falling and colliding, and also allows the holder main body to be pulled up smoothly.

[Embodiments of the invention]

The present invention will be described below with reference to embodiments shown in the drawings.

FIG. 1 shows a roll paper holder according to the present invention.

This roll paper holder [1 includes a base frame 14 for supporting a holder main body 12 within a device housing 13. This base frame 14 is formed in an L-shape, and a rail 15 is erected on the bottom plate 14 a j of the base frame 14 . The holder main body 12 can be slid freely on the rail 15 ζ
This is installed. A pin 16 is implanted on one side 12a4 of the holder body 12, and a handle 17 is implanted on the upper surface 12b. Additionally, a rack 18 is formed on the other side surface 12C of the holder main body 12. On the other hand, a pinion is supported on the side plate 14b of the base frame 14 via a one-way rotary damper 19, and this pinion is engaged with the rack 18.

The one-way rotary damper 19 has a pinion-applied shaft 20.
It consists of a one-way clutch fitted with an inner race and a friction ring that applies rotational resistance to the outer race of the one-way clutch.When the pinion is applied and rotates in the direction of the arrow, the one-way clutch is locked and the one-way clutch is closed. The outer race of the pinion is rotated while being subjected to resistance by the friction ring, and when the pinion is rotated in the opposite direction to the arrow for applying the pinion, the one-way clutch is unlocked and the pinion field is rotated without being subjected to resistance by the friction ring.

The roll paper holder 11 configured in this way is
The base frame 14 is installed in the equipment housing 13 by fixing the bottom plate 14a of the base frame 14 to the internal bottom surface f of the equipment housing 13. Roll paper holder 1 installed in this way
1, the upper end of the holder main body is located directly below the upper opening 13a of the device housing 13.

The operation of the roll paper holder 11 will be explained below.

Insert your hand into the device housing 13 through the upper opening 13a and remove the handle 1.
7 and pull up the holder body 12. Then, the upper half of the holder body 12 is pulled out of the device housing 13 as shown in FIG. Then, the core n of the roll paper 21 is fitted into the pin 16f of the holder main body 12. Then, the holder body 12 descends into the device housing 13 due to the gravity of the roll paper 21, and the lower end surface of the holder body 12 hits the upper surface of the bottom plate L4a of the base frame 14 and is stopped. During this time, the descending speed of the holder main body 12 is appropriately suppressed to f by the resistance of the one-way low and tally damper 19, and the predetermined position t is quietly set.

When the roll paper is used up, the operator puts his hand into the device housing 13 through the upper opening 13a again, hooks his finger on the handle 17, and pulls up the holder main body 12. Then, the holder main body 12 becomes
It can be easily pulled up without receiving any resistance from the one-way rotary damper 19. Then, the core n is removed from the pin 16, and a new roll paper 21 is fitted onto the pin 16f.

In the above embodiment, the moving force control means for the holder body 12 is formed in the rack 18, the pinion (9) meshed with the rack 18, and the one-way mechanism in which the pinion I is supported on the base frame 14. However, in the present invention, without being limited to such a structure, for example, a friction member may be attached to the free end of the lever, and the friction member may be attached to the holder body 12. When the holder body 12 moves toward the base of the rail 15, the friction member comes into contact with the holder body vertices, and the holder body 12 comes into contact with the free surface of the rail 15. The friction member may be configured to escape when moving toward the end.

〔Effect of the invention〕

As described above, in the roll paper holder of the present invention, the holder body can be pulled out from the equipment housing, so the roll paper can be easily replaced, and the holder body can be dropped at a low speed along the rail E. As a result, the roll paper can be quietly loaded into a predetermined position within the device housing, which simplifies the operation and ensures stable feeding of the roll paper.
