Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording device using a pencil pen, and more particularly, when a pencil lead related to recording of the pencil pen is worn out, a new pencil is newly added. The present invention relates to a recording device using a pencil pen of a type having a lead supplying device for supplying a lead. 2. Description of the Related Art Conventionally, there have been two types of conventional core feeding devices for recording apparatuses of this type. The first type uses a pencil pen provided with a lead storage container as a lead tank on the upper portion of the pencil pen and a lead chuck mechanism provided between the lead tank and the tip of the pencil pen. is there. It has been attempted to feed a plurality of pencil leads held in a lead tank to the tip of a pencil pen one by one by causing the lead chuck mechanism to perform a gripping and releasing operation so as to perform continuous recording. (For example, JP-A-3-114797
In the second method, the pencil pen to be refilled is positioned immediately below the lead storage container, and a lead drop mechanism for dropping or not dropping the pencil lead to the lead storage container is provided. As a result, a new pencil lead is dropped and fed into the pencil pen to be fed. (Japanese Patent Application Laid-Open No. 64-78899) [Problems to be Solved by the Invention] The conventional apparatus has the above-mentioned methods, each of which has its own characteristics. There are some points left to be improved. That is, in the case of the first method, when a plurality of pencil leads in the lead tank of the pencil pen itself are used up, the lead supplying device is not particularly provided, so the user can manually I needed to replenish it. In general, at most, several tens of pencil leads can be held in the lead tank of the pencil pen itself, which is insufficient in some cases. Further, one type of the second system is one provided with a lead chuck mechanism for holding and releasing the pencil lead in a lead storage container holding a plurality of pencil leads which are separate from the pencil pen. there were. When the lead chuck mechanism incorporated in the lead storage container is opened, the pencil lead held by the lead storage container is naturally dropped and supplied into the pencil pen to be fed. In this device, in which the pencil lead is naturally dropped to supply the pencil lead, it is necessary to provide a relatively complicated mechanism for controlling the fall of the pencil lead. That is, in the above example, simply opening the lead chuck mechanism for holding the lead lead causes a plurality of pencil leads held in the lead storage container to drop one after another. It is necessary to control whether to stop the fall of the pencil lead at that point. For this reason, in such a device, a drop opening prevention device for dropping or not dropping the pencil lead is provided. Ordinary pencil lead is 0.2mm or
It is extremely thin, such as 3 mm, and it was necessary to have an extremely advanced technique to construct a mechanism for preventing such a pencil lead from dropping when it falls. Therefore, the present invention has been made in view of these points, and an object thereof is to provide an apparatus which is relatively simple in structure and which can supply a pencil lead into a pencil pen from the outside. Therefore, according to the present invention, a lead chuck mechanism is provided in the lead storage container, and the lead chuck mechanism is made to perform a gripping and releasing operation one after another. The pencil lead is gradually fed out, and the lead opening of the pencil pen to be fed can be positioned close to the lead outlet of the lead storage container. The pencil pen to be cored is positioned at the core position.
The lead opening of the pencil pen is arranged close to the lead outlet of the lead storage container. In this state, the lead chuck member built in the lead storage container is grasped and released. A pencil lead can be supplied by repeating this several times. This pencil lead supply operation requires a relatively large number of gripping and releasing operations of the lead chuck member, but is configured to be performed while the pen block of the apparatus is performing a recording operation by another pencil pen or recording pen. By doing so, it can be implemented without any problems. 1 to 4 respectively illustrate a recording device using a pencil pen according to an embodiment of the present invention. FIG. 1 shows this recording device including a pencil lead supplying device. 2 is an explanatory view for schematically explaining a mechanism for removing unnecessary cores of this apparatus, FIG. 3 is an explanatory view for schematically explaining a core supply mechanism of this apparatus, and FIG. It is explanatory drawing which illustrates a completion detection method typically. First, with reference to FIG. 1, the overall structure and operation of the apparatus of this embodiment will be described. The apparatus shown in FIG. 1 includes a pen block 1 for holding a pencil pen 7 in a moving part pen holder 11 and moving it on a medium (not shown) in a predetermined direction, and a moving part pen holder 11 of the pen block 1. A storage pen holder 2 capable of mutually holding a large number of recording pens including the pencil pen in cooperation with each other, and a motor 3 for rotating the storage pen holder 2 in a predetermined direction,
A core-feeding carriage 41 that has a core-holder 42 that can hold the pencil pens in cooperation with the storage pen holder 2 and that can move along a rail 43.
1. The core storage container holding portion 5 for holding a plurality of core storage containers (51 to 54) having the same structure arranged along the moving direction of 1, and the carriage 41 is also arranged along the moving path. It has a core removing mechanism 6 including a core removing rod 61 and a core removing section 62 for removing an unnecessary core of the pencil pen 7. Pencil pen 7 used in the apparatus of this embodiment
2 or 3, a so-called cartridge-type pencil pen in which a core passage for guiding the pencil lead 713 is formed in the central portion of the pencil pen 7 and an O-ring 711 is fitted near the tip thereof. It is of the form called. Therefore, in the pen block 1 of the apparatus shown in FIG. 1, when the pencil pen 7 is held and recording is performed, the pencil lead 713 of the held pencil pen 7 is gradually pushed out along with the recording (not shown). Have). The storage pen holder 2 is configured to be capable of holding a large number of recording pens including a plurality of pencil pens 7, and cooperates with the moving pen holder 11 of the pen block 1 to provide various pencil pens 7. It has a structure in which the recording pens can be exchanged and held with each other. Further, the storage pen holder 2 is connected to the motor 3 and is configured to be rotatable in a predetermined direction so that a specific recording pen can be selected from various pens. The core feeding carriage 41 is constructed so as to be movable on the rail 43, and the core feeding holder 42 cooperates with the storage pen holder 2 to exchange and hold the pencil pen 7. There is. Further, the core feeding carriage 41 is provided with an actuator (not shown) for moving the core feeding holder 42 up and down by a predetermined stroke, and the pencil pen held by the actuator can be moved up and down as necessary. Has been done. Further, the core feeding carriage 41 is controlled by a control means (not shown) of the apparatus so as to be able to take three positions of a pen replacement position, a core feeding position and, if necessary, a core discharging position. When 41 reaches the pen replacement position, its core holder 42
Has a structure in which the replacement operation is performed for a specific pencil pen 7 in cooperation with the storage pen holder 2. It should be noted that both the pen exchanging operation and the pen exchanging operation between the moving pen holder 11 of the pen block 1 and the storing pen holder 2 described above can be performed by using a well-known pen exchanging technique. When recording is performed by the pen block 1 and the pencil lead 713 related to the recording is consumed and the recording is no longer possible, it is necessary to supply a new pencil lead 713. Therefore, the unrecordable pencil pen 7 held in the pen block 1 is temporarily held in the storage pen holder 2 for core feeding. In the pen block 1, recording is continued using another pencil pen 7. The unrecordable pencil pen 7 held by the storage pen holder 2 is positioned at an exchange position between the core carriage 41 and the core holder 42 by rotation of the storage pen holder 2 at a predetermined angle. Then, it is held by the core holder 42 of the core carriage 41. At this time, in the case where there is an unnecessary lead 713, which is consumed by recording, with respect to the unrecordable pencil pen 7 held by the lead feeding carriage 41, it is first unnecessary before the feeding operation. The core 713 ejecting operation is performed. The core feed carriage 41 positions the pencil pen 7 it holds at the core discharge position. At this lead-out position, the lead-out rod 61 of the lead-out mechanism 6 corresponds to the lead-in port 71 of the pencil pen 7, and the lead-out removal section 62 is attached to the lead outlet (not shown) at the tip of the pencil pen 7. It is the corresponding position. The discharge rod 61 is lowered by a drive source (not shown), and the unnecessary lead 713 held by the pencil pen 7 is pushed out of the pencil pen 7,
The core removal unit 62 removes the unnecessary core 713. The pencil pen 7 from which the unnecessary lead 713 has been removed or the pencil pen 7 to be refilled that does not require the above-mentioned unnecessary lead removal operation is positioned at the refilling position. A wick storage container holding portion 5 is provided at this feeding position. In this embodiment, the lead storage container holding unit 5 includes four lead storage containers (5 that hold a plurality of pencil leads of different thicknesses).
1 to 54) are slidably held. Therefore, when the core feeding carriage 41 moves while holding the pencil pen 7 to be cored and reaches the core position, the core opening 714 of the specific pencil pen 7 to be held corresponds to the corresponding core storage container (51 to 51). 54 any one of) core delivery port (512-5)
42). At this stage, the feeding operation is started.
The core holder 42 is moved up and down by an actuator provided in the core carriage 41. Therefore, the pencil pen 7 held by the lead holder 41 moves up and down, and the corresponding lead storage containers (51 to 54) slide up and down. Each core storage container (51-54) is slid up and down, and thereby the core chuck mechanism (515) incorporated therein.
Up to 545), the grip release operation is performed. Therefore, a plurality of up and down movements of the above-mentioned actuator are performed via the pencil pen 7 to which the lead is to be fed.
4) make the slide operation, and hold the pencil lead 71.
3 is fed to this pencil pen 7 and supplied. By performing such an operation, the apparatus of this embodiment eliminates unnecessary pencil lead and supplies a new pencil lead, if necessary. Next, detailed operation of each of the above steps will be described with reference to FIGS. Figure 2
[Fig. 6] is a schematic diagram for explaining an operation of removing unnecessary cores.
When the unnecessary lead is removed, the lead holder 42 of the lead carriage 41 shown in FIG. 1 holds the pencil pen 7 having the unnecessary lead 713, and the pencil pen 7 is placed at the right end side discharge position. Position it. The ejector rod 61 of the ejector mechanism 6 is lowered by an actuator (not shown). The lead-out rod 61 is inserted into the pencil pen 7 through the lead-in port at the upper end of the pencil pen 7, and tries to push the unnecessary lead 713 out of the pencil pen 7 as shown in the drawing on the right side of FIG. As described above, the pencil pen 7 is a cartridge type that holds one pencil lead 713, and the pencil lead 713 is supported by the O-ring 711 at the lower end. Therefore, when the unnecessary core 713 is pushed out by the core exhaust rod 61 as it is, the core exhaust rod 6 is
1 may damage the O-ring 711. For this reason, in this device, as shown in the right end view of FIG. 2, the discharge core rod 61 is pushed to just above the O-ring 711 of the pencil pen 7. At this time, the unnecessary core 713 is in a state in which the tip thereof is sandwiched by the core removal section 62 made of a material having a relatively high friction coefficient such as rubber. The sensor 63 (this sensor 63
Is provided in the housing of the apparatus, and the core feeding carriage 41 is also provided.
It may be provided at a predetermined position. ) Is for detecting the discharge core. From this state, as shown in the central view of the figure, the core lead-out rod 61 is driven upward and pulled out from the pencil pen 7. Further, as shown in the left end view of the drawing, the pencil pen 7 is driven upward by the actuator of the lead carriage 41, and the unnecessary lead 713 held by the pencil pen 7 is taken out of the pencil pen 7. At this point, the removal of the unnecessary lead of the pencil pen 7 is completed, but it is necessary to process the unnecessary lead 713 piercing the lead removal section 62 for the next lead removal operation of the other pencil pens 7. There is. Therefore, the feeding carriage 41 moves a little and performs an operation of pushing the unnecessary lead 713 into the core removing portion 62 by the tip of the pencil pen 7 as shown in the left end view of FIG. In this way, all the unnecessary core removing operations are completed. FIG. 3 is a schematic diagram for explaining the core feeding operation for the pencil pen 7 to be core-filled. In the state shown in FIG. 3, the pencil pen to be fed is the lead feeding carriage 4 shown in FIG.
The pencil pen 7 is held by the first lead holder 42 and is positioned in the vicinity of the lead storage container 51 holding the pencil lead to be fed.
1 is slightly pushed up by the actuator of No. 1 and the core feeding port 714 of the pencil pen 7 is connected to the lead delivery port 51 of the lead storage container 51.
2 shows the state of being in contact with 2. In this state, the pencil pen 7 is vertically moved a plurality of times by the actuator of the core feeding carriage 41. When the pencil pen 7 is moved upward, the case 516 of the lead storage container 51 is pushed up. However, the wick tank 511 of the wick storage container 51 does not move because its upper end is in contact with the bent portion of the wick storage container holding portion 5 shown in FIG. Therefore, the lead chuck mechanism 515 supported below the lead storage container 51 is projected, and the lead chuck mechanism 515 is opened. When the lead chuck mechanism 515 is opened, the pencil lead 713 is fed out by a predetermined amount. When the pencil pen 7 is lowered by the action of the actuator of the lead carriage 41, the case 516 of the lead storage container 51 is also lowered correspondingly. Therefore, the lead chuck mechanism 515 is pulled back relatively upward to grip the pencil lead 713. In this way, by repeatedly moving the pencil pen 7 up and down by the actuator of the lead feeding carriage 41, a new pencil lead can be drawn out from the lead storage container 51. In the apparatus of this embodiment, as shown in FIG. 3, the tip of the drawn pencil lead 713 is supported by the O-ring 711 at the tip of the pencil pen 7 by the feeding operation of the pencil lead 713. Configured to do. Although not shown in FIG. 3, at this stage, the pencil lead 713 is configured to be slightly extended from the tip portion of the pencil pen 7, and a sensor is provided at a predetermined position of, for example, the lead feeding carriage 41, so that the sensor described above is used. It is possible to detect whether or not the pencil lead 713 supplied by the operation of has reached an appropriate position. FIG. 4 schematically shows another example of the method for monitoring the proper supply of the pencil lead 713.
The pencil pen 7 to which the pencil lead 713 has been supplied by the above operation
Is positioned at the core discharge position by the core supply carriage 41. As shown in the right end view of FIG. 4, the supplied pencil lead 713 is slightly pushed out by the discharge core rod 61, and the sensor 63
It is recognized that the proper supply is performed by considering the detection result of 1) and the amount of lowering of the core discharge rod 61 by the internal control means. Next, as shown in the left end diagram of the figure, the lead-out rod 61 is pulled out, and the lead-feeding carriage 41 is moved by a slight amount to push back the pencil lead 713 where the pencil pen 7 has come out to an appropriate position. . As described above, in the apparatus of this embodiment, when the pencil lead relating to recording is consumed and becomes an unnecessary lead, the unnecessary lead is removed and a new pencil lead 713 is added.
The operation of each of these elements is controlled by the control means of the apparatus. In the apparatus of this embodiment, a refilling carriage for moving a replacement position for holding the pencil pen 7 to be refilled and ejected, a refilling position for supplying a new pencil lead, and a refilling position for removing unnecessary lead. In the above example, a holder having only the core feeding element and a holder having only the core discharging element are provided at a predetermined position of the apparatus, and the core is directly fed and discharged from the pen block of the apparatus. The pencil pens 7 should be held in their respective holders to perform core feeding or core discharging operations as needed. As described above, according to the present invention, it is possible to realize a recording apparatus using a pencil pen which can reliably perform core feeding with a relatively simple structure.
